SUMMARY OF RISKS ASSOCIATED WITH OUR BUSINESS

Our business is subject to numerous material and other risks and uncertainties, including those described in “Item 3.D.—Risk Factors” in this annual report. The principal risks and uncertainties affecting our business include the following:

We are substantially dependent on the commercial success of the global Nefecon franchise. If we are unable to successfully commercialize Nefecon or experience significant delays in doing so, our business will be materially harmed.
If we are unable to successfully complete clinical development of, obtain regulatory approval for and successfully commercialize the global Nefecon franchise and our present or future product candidates, or experience significant delays in doing so, our business will be materially harmed.
The regulatory approval processes of the FDA, EC and comparable foreign regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain acceptance for filing and regulatory approval for any of our products or present or future product candidates, our business will be substantially harmed.
The use of proteinuria as a surrogate endpoint to support initial approvals of Nefecon is a novel approach in nephrology.
Our clinical trials may fail to adequately demonstrate the safety and efficacy of any of our product candidates, which would prevent or delay regulatory approval and commercialization.
The results of early-stage clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Initial success in a clinical trial may not be indicative of results obtained when these trials are completed or in later-stage trials.
Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may be impacted as additional patient data become available and are subject to audit and verification procedures that could result in material changes in the conclusions based on the final analysis of the complete data set.
The target patient population of Nefecon for the treatment of IgAN is small and has not been definitively determined, and if the number of treatable patients for Nefecon or our present or future product candidates is lower than expected, our potential product sales revenues and our ability to achieve profitability would be compromised.
We were not involved in the early development of setanaxib; therefore, we are dependent on third parties having properly conducted setanaxib’s preclinical research, manufacturing control and clinical development.
We face significant competition for our drug discovery, development and commercialization efforts, and if we do not compete effectively, our commercial opportunities will be reduced or eliminated.
If we fail to develop and commercialize other product candidates in addition to Nefecon, such as setanaxib, we may be unable to grow our business and our ability to achieve our strategic objectives would be impaired.
We have only recently begun commercialization of the global Nefecon franchise and we have never previously commercialized a product. We may lack the necessary expertise, personnel and resources to successfully commercialize Nefecon or any other approved products on our own or together with suitable partners.
We have incurred significant losses since our inception and anticipate that we will continue to incur operating losses for the near future.
We may need substantial additional funding in order to fund our operations. Failure to obtain this necessary capital at acceptable terms and when needed may force us to delay, limit or terminate certain or all of our operations and pursuit of our growth strategy.

4

Table of Contents

We have a limited operating history as a commercial company, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.
We have entered into agreements with third parties to develop and commercialize Nefecon in jurisdictions outside the United States, if approved in such jurisdictions, and we plan to enter into additional agreements in the future with respect to any of our present or future product candidates that receive approval. If we are unable to establish and maintain such collaborations, we may not be successful in our commercialization efforts. If our commercialization partners do not to satisfy their obligations or are unsuccessful, we could be adversely affected.
We expect to continue to expand our development, regulatory and sales and marketing capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.
Our business is subject to economic, political, regulatory and other risks associated with international operations.
We have identified material weaknesses in our internal control over financial reporting. If our remediation of these material weaknesses is not effective, or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations.
We are dependent on third parties to manufacture and distribute our products.
Healthcare reform initiatives, unfavorable pricing regulations, and changes in reimbursement practices of third-party payers or patients’ access to insurance coverage could affect the pricing of and demand for our products.
We may be unable to successfully integrate new products or businesses we may acquire.
We may become involved in litigation matters, which could result in substantial costs, divert management’s attention and otherwise have a material adverse effect on our business, operating results or financial condition.
We may not have sufficient insurance to cover our liability in any current or future litigation claims either due to coverage limits or as a result of insurance carriers seeking to deny coverage of such claims.

D.RISK FACTORS

Our business faces significant risks. You should carefully consider all of the information set forth in this annual report and in our other filings with the US Securities and Exchange Commission, or the SEC, including the following risk factors which we face and which are faced by our industry. Our business, financial condition or results of operations could be materially and adversely affected if any of these risks occurs. This report also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors including the risks described below and elsewhere in this annual report and our other SEC filings. See “Special Note Regarding Forward-Looking Statements” above.

Risks Related to the Development and Commercialization of Our Product Candidates

We are substantially dependent on the commercial success of the global Nefecon franchise. If we are unable to successfully commercialize Nefecon or experience significant delays in doing so, our business will be materially harmed.

We have sold Nefecon in the United States (marketed under the brand name TARPEYO) only since January 2022 and our commercial partner in Europe, STADA, launched Kinpeygo in Germany in October 2022 and in Greece under a Special Import License since June 2023. Our net sales for the year ended December 31, 2023 were SEK 1,206.9 million, of which TARPEYO net sales amounted to SEK 1,075.8 million. We do not know whether such revenue levels will increase or be maintained in the future. Other than Nefecon, which has been granted full approval in the United States, conditional marketing authorization in the EU and the UK, and conditional approval for sale in Macau in October 2023, China in November 2023 and Singapore in March 2024, we currently have no products approved for commercial sale. Our success as a company is substantially dependent on our ability to generate revenue from sales of the global Nefecon franchise, which will depend on many factors including, but not limited to, our ability to:

maintain full approval of TARPEYO in the US;
execute our sales and marketing strategies for TARPEYO;
maintain and manage the necessary sales, marketing and other capabilities and infrastructure that are required to continue to successfully commercialize TARPEYO in the US;

6

Table of Contents

achieve, maintain and grow market acceptance of the global Nefecon franchise and demand for TARPEYO;
establish or demonstrate in the medical community the safety and efficacy of Nefecon as compared to marketed products and product candidates currently in clinical development;
secure payor approval of TARPEYO for the patient population on acceptable terms;
offer TARPEYO at competitive prices as compared to alternative options, and our ability to achieve a suitable profit margin on our sales of TARPEYO;
adapt to additional changes to the label for TARPEYO in the US that could place restrictions on how we market and sell it, including as a result of adverse events observed in NefIgArd or other studies;
obtain and deliver adequate and timely supplies of Nefecon, which may in the future be adversely affected by factors relating to pandemics, geopolitical tension, global supply chain disruptions and other world events;
comply with applicable legal and regulatory requirements;
deliver Nefecon to our partners in a timely manner;
maintain necessary state pharmaceutical distribution licenses and permits required for the sale of TARPEYO and a pharmacovigilance system satisfying applicable legal and regulatory requirements;
maintain our arrangements with third party logistics providers and specialty pharmacies to distribute TARPEYO to customers and to provide related patient and administrative support services;
enforce our intellectual property rights in and to TARPEYO and the global Nefecon franchise; and
avoid third-party patent interference or intellectual property infringement claims.

If we do not achieve or maintain one or more of these factors, many of which are beyond our control, in a timely manner or at all, we may not be able to generate material and continuing revenue from sales of Nefecon, which may materially impact the success of our business.

If we are unable to successfully complete clinical development of, obtain regulatory approval for and successfully commercialize the global Nefecon franchise and our present or future product candidates or experience significant delays in doing so, our business will be materially harmed.

We have not completed the clinical development of any product candidates other than TARPEYO and Kinpeygo and we cannot guarantee that any present or future product candidates will ever become marketable drug products. We also must successfully complete clinical development of Nefecon in order to achieve full marketing approval in the EU and the UK.

Table of Contents

To date, we have invested our efforts and financial resources primarily in the research and development of the global Nefecon franchise, and to building marketing, sales, market access and medical affairs functions in the United States. Nefecon was granted accelerated approval by the FDA in December 2021 and received full approval in December 2023. In July 2022, Nefecon was granted conditional marketing authorization by the EC. In February 2023, the UK Medicines and Healthcare Products Regulatory Agency, or MHRA, also granted conditional marketing authorization for Nefecon. Our partner STADA has submitted requests to the EMA in September 2023 for the EU and to the MHRA in October 2023 for the UK to convert the current conditional marketing authorization for these territories into a full marketing authorization. We reported the full data from the Phase 3 NefIgArd clinical trial in August 2023. The trial met its primary endpoint with Nefecon demonstrating a highly statistically significant and clinically relevant benefit over placebo (p value < 0.0001) in eGFR over the two-year period of nine months of treatment with Nefecon or placebo and 15 months of follow-up off drug. The results indicate that Nefecon was generally well-tolerated, with the majority of treatment-emergent adverse events (TEAE) being mild or moderate, and with TEAEs leading to discontinuation of the study in less than 10% of patients. Although we believe that the data from the Phase 3 NefIgArd clinical trial supports our commercialization partners’ regulatory filings for full approval in the EU and the UK, we cannot guarantee that Nefecon will receive full regulatory approvals on the timelines we expect or at all.

We are also developing setanaxib for the treatment of primary biliary cholangitis, or PBC, a fibrotic orphan disease, for the treatment of squamous cell carcinoma of the head and neck, or SCCHN, and for the treatment of Alport syndrome. Setanaxib has shown clinically relevant anti-fibrotic activity in a Phase 2 clinical trial in PBC, despite not achieving its primary endpoint. We are currently evaluating setanaxib in the TRANSFORM study, a Phase 2b clinical trial, in which we randomized the first patient in February 2022. Setanaxib will be administered to approximately 70-80 patients with PBC and elevated liver stiffness as well as intolerance or inadequate response to ursodeoxycholic acid, a generic drug also known as ursodiol or UDCA in a global trial conducted in 80-130 investigational centers in North America, the EU, Israel, Australia and New Zealand. The primary endpoint is alkaline phosphatase (ALP) reduction, with key secondary endpoints including change in liver stiffness and effect on fatigue and pruritus (itching). Following favorable safety data from a Phase 1 study, this trial will evaluate two dosing regimens of 1200mg/daily and 1600mg/daily. We expect to read out data in the third quarter of 2024, and this analysis will determine which dose of setanaxib will be used for a future potential Phase 3 study. Setanaxib was granted fast track designation by the FDA in August 2021.We are also currently conducting a Phase 2, proof-of-concept trial of setanaxib in patients with SCCHN, which is evaluating administration of setanaxib in conjunction with immunotherapy targeting cancer-associated fibroblasts. The first patient was randomized in this trial in the second quarter of 2022 and we reported interim data in July 2023. The analysis reflected encouraging early clinical progression-free survival (PFS) results and was supportive of the presumed anti fibrotic mode of action of setanaxib. We expect to report a full data readout from this trial in the second quarter of 2024. We are also currently conducting a Phase 2 clinical trial of setanaxib in Alport syndrome, which we initiated in November 2023. Finally, setanaxib is being evaluated in an investigator-led Phase 2 study in idiopathic pulmonary fibrosis, with topline data readout expected in the fourth quarter of 2024.

Our near-term prospects, including our ability to finance our operations and generate revenue, will depend substantially on the successful development and commercialization of the global Nefecon franchise and, to a lesser degree, setanaxib. The clinical and commercial success of Nefecon, setanaxib and any other present or future product candidates will depend on a number of factors, including:

the timely completion of our planned and ongoing clinical trials;
our ability to demonstrate Nefecon’s and our present or future product candidates’ safety and efficacy to the satisfaction of the FDA, the EC or comparable foreign regulatory authorities based on the endpoints that we are evaluating in our planned and ongoing clinical trials;
our ability to comply with any requirements imposed by the FDA, the EC or comparable foreign regulatory authorities to conduct additional clinical trials in connection with approval to market Nefecon or our product candidates, including any additional testing following any accelerated approval or conditional authorization by such regulatory authorities;
our ability to obtain and maintain marketing approvals in the US, the EU, the UK or other jurisdictions;
our ability to obtain regulatory approval based on the data from the NefIgArd trial, to demonstrate safety and efficacy in our Phase 2b TRANSFORM trial evaluating setanaxib in PBC and to establish proof of concept in our Phase 2 trials of setanaxib in SCCHN and Alport syndrome;

Table of Contents

the prevalence and severity of adverse side effects of Nefecon and our present or future product candidates;
our ability to successfully commercialize TARPEYO and our present or future product candidates, if and when approved for marketing and sale by the FDA, the EC or comparable foreign regulatory authorities, whether alone or in collaboration with others;
our ability to develop, validate and maintain commercially viable manufacturing and testing processes and procedures that are compliant with current good manufacturing practices, or cGMP, and accepted by regulatory authorities;
the ability of our third-party manufacturers to manufacture quantities of Nefecon and our present or future product candidates using commercially sufficient processes complying with applicable regulatory requirements and practices at a scale sufficient to meet anticipated demand;
our success in educating physicians and patients about the benefits, risks, administration and use of Nefecon and our present or future product candidates;
achieving and maintaining compliance with all regulatory requirements applicable to Nefecon and our present or future product candidates;
acceptance of the Nefecon franchise and our present or future product candidates as safe and effective by patients and the medical community;
the availability, perceived advantages, relative cost, relative safety and relative efficacy of alternative and competing treatments;
our ability to obtain and sustain an adequate level of coverage and reimbursement for Nefecon and our present or future product candidates by third-party payors and patients’ willingness to pay out-of-pocket in the absence of such coverage and adequate reimbursement;
the effectiveness of our own or any future strategic collaborators’ marketing, sales and distribution strategy and operations;
our ability to obtain, maintain, protect and enforce our intellectual property rights in and to Nefecon and our present or future product candidates;
our ability to avoid and defend against third-party patent interference or patent infringement claims or other intellectual property related claims;
a continued acceptable safety profile of Nefecon and our present or future product candidates following approval; and
our ability to raise sufficient capital resources to fund the commercialization of our approved products.

Table of Contents

Many of these factors are beyond our control. If we are not successful with respect to one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize Nefecon or our present or future product candidates, which would materially harm our business. In addition, even if we were to obtain approval, regulatory authorities may approve our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge for our products, may grant approval contingent on the performance of costly post-marketing clinical trials, may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Third-party payors or insurers may also condition or limit reimbursement of our products. Any of the foregoing scenarios could materially harm the commercial prospects for Nefecon, setanaxib and any other product candidates we develop. If we are not successful in commercializing Nefecon or our present or future product candidates, or are significantly delayed in doing so, our business will be materially harmed.

The regulatory approval processes of the FDA, EC and comparable foreign regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain acceptance for filing and regulatory approval for any of our products or present or future product candidates, our business will be substantially harmed.

The time required to obtain approval by the FDA, EC and comparable foreign regulatory authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, laws or regulations or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. To date, Nefecon has received full approval from the FDA (under the brand name TARPEYO) and conditional marketing authorization in the EU and the UK (under the brand name Kinpeygo). Although our partner STADA has submitted requests to both the EMA, in September 2023, for the EU and to the MHRA, in October 2023, for the UK to convert the current conditional marketing authorization for these territories into a full marketing authorization, it is possible that we and our licensees may not be able to obtain full marketing approval in these jurisdictions. Our partner Everest Medicines II Limited, or Everest, has received conditional approval for Nefecon in Macau in October 2023, in Singapore (under the brand name NEFEGAN) in March 2024, and in China, with us as the marketing authorization holder in November 2023. It is possible that we and our licensee may not be able to obtain approval for Nefecon in additional jurisdictions, or approval for setanaxib or other product candidates we may seek to develop in the future.

Any of our product candidates, including setanaxib and Nefecon, could fail to receive regulatory approval for many reasons, including the following:

to the extent that we seek approval for any additional product candidates based on evaluation of a surrogate marker, including as we did for Nefecon, we may be unable to utilize the accelerated approval pathway under Subpart H of the FDA’s New Drug Application, or NDA, regulations and comparable regulations promulgated in the EU or elsewhere if the appropriate regulatory authorities do not accept the proposed surrogate marker as the basis for an accelerated/conditional approval;
the data collected from clinical trials of a product candidate may not be sufficient to support the submission of an NDA to the FDA or other submission or to obtain regulatory approval in the United States, the EU or elsewhere;
the scientific advice and regulatory feedback provided by the FDA, the EMA, or comparable foreign regulatory authorities, as applicable, during the drug development phase is not legally binding, and the FDA, the EMA may depart from such advice and feedback on the basis of justified grounds during assessment of future marketing authorization applications;
we may be unable to demonstrate to the satisfaction of the FDA, the EMA and the EC or comparable foreign regulatory authorities that a product candidate is safe or effective for its proposed indication;
the results of clinical trials may not be sufficiently statistically significant or clinically meaningful as required by the FDA, the EMA, the EC or comparable foreign regulatory authorities for approval;
we may be unable to demonstrate that the product candidate’s clinical and other benefits outweigh its safety risks;

10

Table of Contents

the FDA, the EMA, the EC or comparable foreign regulatory authorities may disagree with our interpretation of data from clinical trials;
the FDA, the EMA, the EC or comparable foreign regulatory authorities may find deficiencies with or fail to approve the manufacturing processes, quality control procedures or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and
the approval policies or regulations of the FDA, the EC, or comparable foreign regulatory authorities or the laws they enforce may significantly change in a manner rendering our clinical data insufficient for approval.

This lengthy process towards approval as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to market any of our product candidates, which would significantly harm our business, financial condition and results of operations. The FDA, EMA, EC and other comparable foreign regulatory authorities have substantial discretion in the approval process and determining when or whether regulatory approval will be obtained for any of our product candidates. Even if we believe the data collected from clinical trials of our product candidates are promising, such data may not be sufficient to support approval by the FDA, the EC or other comparable foreign regulatory authorities.

Additionally, disruptions at the FDA and other comparable foreign regulatory authorities and agencies may also lengthen the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which could adversely affect our business. For example, in 2018 and 2019, the US government shut down several times and certain regulatory agencies, such as the FDA and the SEC, had to furlough critical employees and stop critical activities. If a prolonged government shutdown occurs in the future, our ability to obtain approval of our product candidates from the FDA and comparable foreign regulatory authorities may be adversely impacted.

Accelerated approval by the FDA, and conditional approval by the EC, even if pursued for any future product candidates, may not lead to a faster development process or regulatory review and does not increase the likelihood that our product candidates will receive marketing approval. If we are not successful with this process, the development or commercialization of such product candidates could be delayed, abandoned or become significantly more costly.

In certain circumstances, the FDA selectively allows the use of surrogate endpoints to permit a faster development and an accelerated approval path.

As a condition of approval, regulatory agencies may impose specific obligations, including the requirement to perform adequate and well-controlled post-marketing clinical trials. These confirmatory trials must be completed with due diligence. The additional data generated through other post-marketing clinical trials may not confirm that the benefit-risk balance of a future product candidate is positive or the burden to further complete the post-approval obligations may become too high.

In the EU and UK, a conditional marketing authorization is valid for one year and must be renewed annually until all specific obligations have been fulfilled. Once all pending study results are provided, the conditional marketing authorization can be converted into a traditional marketing authorization. However, if the obligations are not fulfilled within the timeframe set by the EC, the marketing authorization will cease to be renewed. Complying with the conditions of the marketing authorization may require financial resources and time. STADA, our commercialization partner, may not be able to comply with all required conditions and may need to withdraw the marketing authorization. Although our partner STADA has submitted requests to both the EMA, in September 2023, for the EU and to the MHRA, in October 2023, for the UK to convert the current conditional marketing authorization for these territories into a full marketing authorization the EC or the MHRA may decide not to grant this request. An analysis of reimbursement decisions by the competent authorities of the individual EU Member States for conditionally authorized medicines in the EU has shown some delays in the timeline for reaching a positive health technology recommendation. If this happens for Kinpeygo or any other present or future product candidate, it may delay the timing and success of the commercialization of such product.

The use of proteinuria as a surrogate endpoint to support initial approvals of Nefecon is a novel approach in nephrology.

There can be no assurances that regulatory authorities in countries where we seek regulatory approval of Nefecon will ultimately accept the outcome of the NefIgArd trial with regards to proteinuria and eGFR for the approval of Nefecon. Regulatory authorities may require us to provide additional data to support our regulatory applications, which may increase the complexity, uncertainty and length of the regulatory approval process for Nefecon. The EC and comparable foreign regulatory authorities may also withdraw any conditional approval granted for Nefecon if Part B, the post-approval confirmatory phase of the NefIgArd trial, is not considered to have confirmed the positive clinical benefit-risk balance of Nefecon in the approved indication and the EC for the EU and to the MHRA for the UK may refuse the request to convert the current conditional marketing authorization for these territories into a full marketing authorization.

Clinical trials are difficult to design and implement, and they involve a lengthy and expensive process with uncertain outcomes. We may experience delays in completing, or ultimately be unable to complete, the development and commercialization of our current and future product candidates.

To obtain the requisite regulatory approvals to commercialize any present or future product candidates, we must demonstrate through extensive clinical trials that our product candidates are safe and effective in humans. Confirmatory clinical trials are required to maintain an accelerated approval in the US or a conditional authorization in the EU and the UK. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Successful completion of clinical trials is a prerequisite to submitting an NDA to the FDA, a Marketing Authorization Application, or MAA, to the EMA and similar marketing applications to comparable foreign regulatory authorities for each product candidate and, consequently, the ultimate approval and commercial marketing of any product candidates. Failure can occur at any time during the clinical trial process and our future clinical trial results may not be successful.

Differences in trial design between early-stage clinical trials and later-stage clinical trials make it difficult to extrapolate the results of earlier clinical trials to later clinical trials. Moreover, clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of their products. Where a randomized, placebo-controlled clinical trial is designed to allow enrolled subjects to cross-over from the placebo cohort to the treatment cohort, there may be a risk of inadvertent unblinding of subjects prior to cross-over, which may limit the clinical meaningfulness of those data and may require the conduct of additional clinical trials.

In addition, we may experience delays in initiating or completing clinical trials. We may also experience numerous unforeseen events during our clinical trials that could delay or prevent our ability to receive marketing approval or commercialize the product candidates we develop, including:

delays in or failure to obtain institutional review board, or IRB, or national competent authority approvals including positive ethics committee opinions for each site;
delays in or failure to recruit a sufficient number of suitable patients to participate in a trial;
failure to have patients complete a trial or return for post-treatment follow-up;
clinical sites deviating from trial protocol or dropping out of a trial;
failure to manufacture sufficient quantities of product candidate for use in clinical trials in a timely manner or shipping delays and interruptions;
safety or tolerability concerns that could cause us or our collaborators, as applicable, to suspend or terminate a trial if we or our collaborators find that the participants are being exposed to unacceptable health risks;
changes in regulatory requirements, policies and guidelines;

Table of Contents

failure of our third-party research contractors to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;
data which we have relied on produced previously by third parties turning out to be different than communicated, resulting in repositioning of the compound and the need for conducting additional trials and analysis;
delays in establishing the appropriate dosage levels in clinical trials; and
the quality or stability of the product candidate falling below acceptable standards.

We could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs or ethics committees of the institutions in which such trials are being conducted, or by the FDA or other comparable foreign regulatory authorities, or recommended for suspension or termination by the Data Review Committee, or DRC, or Data Safety Monitoring Board, or DSMB, for such trial. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other comparable foreign regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, including those relating to the class to which our product candidates belong, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

If we experience delays in the completion of, or if we terminate, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. From time to time, we may interact with regulatory agencies with the aim of facilitating the development of our product candidates by achieving alignment on an efficient trial design, a modest number of enrolled patients or a relatively expedient timeline. However, there can be no assurances that such alignment will be reached and, even if achieved, that we will realize the intended benefits from these interactions.

Moreover, if we make changes to our product candidates, we may need to conduct additional studies to bridge our modified product candidates to earlier versions, which could delay our clinical development plan or marketing approval for our product candidates. Significant clinical trial delays could also allow our competitors to bring products to market before we do or shorten any periods during which we have the exclusive right to commercialize our product candidates and impair our ability to commercialize our product candidates.

Any of these occurrences may harm our business, financial condition and results of operations significantly. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates or result in the cessation of development of our product candidates.

In addition, the policies of the FDA, the competent authorities of the EU Member States, the EMA, the EC and other comparable regulatory authorities with respect to clinical trials may change and additional government regulations may be enacted. For instance, the regulatory landscape related to clinical trials in the EU recently evolved. The EU Clinical Trials Regulation, or CTR, which was adopted in April 2014 and repeals the EU Clinical Trials Directive, became applicable on January 31, 2022. The CTR allows sponsors to make a single submission to both the competent authority and an ethics committee in each EU Member State, leading to a single decision for each EU Member State. The assessment procedure for the authorization of clinical trials has been harmonized as well, including a joint assessment by all EU Member States concerned, and a separate assessment by each EU Member State with respect to specific requirements related to its own territory, including ethics rules. Each EU Member State’s decision is communicated to the sponsor via the centralized EU portal. Once the clinical trial approved, clinical study development may proceed. The CTR foresees a three-year transition period. The extent to which ongoing and new clinical trials will be governed by the CTR varies. For clinical trials in relation to which application for approval was made on the basis of the Clinical Trials Directive before January 31, 2022, the Clinical Trials Directive will continue to apply on a transitional basis for three years until January 31, 2025. By that date, all ongoing trials will become subject to the provisions of the CTR. Compliance with the CTR requirements by us and our third-party service providers, such as CROs, may impact our developments plans.

It is currently unclear to what extent the UK will seek to align its regulations with the EU in the future. The UK regulatory framework in relation to clinical trials is derived from existing EU legislation (as implemented into UK law, through secondary legislation).

On January 17, 2022, the MHRA, launched an eight-week consultation on reframing the UK legislation for clinical trials. The consultation closed on March 14, 2022 and aims to streamline clinical trials approvals, enable innovation, enhance clinical trials transparency, enable greater risk proportionality, and promote patient and public involvement in clinical trials. A decision by the UK not to closely align its regulations with the new approach that will be adopted in the EU may have an effect on the cost of conducting clinical trials in the UK as opposed to other countries and/or make it harder to seek a marketing authorization in the EU for our product candidates on the basis of clinical trials conducted in the UK.

If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies governing clinical trials, our development plans may be impacted.

Our clinical trials may fail to adequately demonstrate the safety and efficacy of any of our product candidates, which would prevent or delay regulatory approval and commercialization.

Before obtaining regulatory approvals for the commercial sale of our products or present or future product candidates, we must demonstrate through lengthy, complex and expensive clinical trials that our products or product candidates are both safe and effective for use in each target indication. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process, and there is a high risk of failure and we may never succeed in developing marketable products.

Clinical trials that we conduct may not demonstrate the efficacy and safety necessary to obtain regulatory approval to market our products or product candidates. In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product or product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants. If the results of current or future clinical trials are inconclusive with respect to the efficacy of our products or product candidates, if we do not meet the clinical endpoints with statistical and clinically meaningful significance, or if there are safety concerns associated with our product candidates, we may be delayed in obtaining, or fail to obtain, marketing approval.

Even if the trials are successfully completed, clinical data are often susceptible to varying interpretations and analyses, and we cannot guarantee that the FDA, the EC, the EMA or other comparable foreign regulatory authorities will interpret the results as we do, and more trials could be required before we can successfully submit our product candidates for approval. We cannot guarantee that the FDA, the EC, the EMA, or other comparable foreign regulatory authorities will view our product candidates as having efficacy even if positive results are observed in clinical trials. To the extent that the results of the trials are not satisfactory to the FDA, the EMA, the EC or other comparable foreign regulatory authorities for support of a marketing application, approval of our product candidates may be significantly delayed, or we may be required to expend significant additional resources, which may not be available to us, to conduct additional trials in support of potential approval of our product candidates.

Some of our clinical trials for our product candidates have been conducted outside the United States, and we may in the future conduct clinical trials for our product candidates, outside the United States, and the FDA, EMA or comparable foreign regulatory authorities may not accept data from such trials.

Some of our clinical trials for our product candidates have been, and we may in the future choose to conduct one or more clinical trials, outside the United States, including in Europe. The acceptance of trial data from clinical trials conducted outside the United States or another jurisdiction by the FDA, EMA, EC, or comparable foreign regulatory authorities may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the US population and US medical practice; and (ii) the trials were performed by clinical investigators of recognized competence and pursuant to Good Clinical Practice, or GCP, regulations. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA, EMA, the EC, or any comparable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA, EMA, the EC, or any comparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may result in product candidates that we may develop not receiving approval for commercialization in the applicable jurisdiction.

The results of early-stage clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Initial success in a clinical trial may not be indicative of results obtained when these trials are completed or in later-stage trials.

Product candidates in later stages of clinical trials, including those with larger numbers of enrolled patients, may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. There can be no assurance that any of our clinical trials will ultimately be successful or support further clinical development of any of our product candidates. There is a high failure rate for drugs proceeding through clinical trials. A number of companies in the pharmaceutical industry have suffered significant setbacks in clinical development even after achieving promising results in earlier preclinical studies and clinical trials, and any such setbacks in our clinical development could have a material adverse effect on our business, financial condition and results of operations.

Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may be impacted as additional patient data become available and are subject to audit and verification procedures that could result in material changes in the conclusions based on the final analysis of the complete data set.

From time to time, we may publish interim, topline or preliminary data from our clinical trials. For example, in July 2023, we announced interim data from our Phase 2 clinical trial of setanaxib in SCCHN and we expect to report the full data readout in the second quarter of 2024. Conclusions or assumptions based on preliminary and interim data from our clinical trials may change as more patient data become available and further analyses are performed. Preliminary or interim data from our clinical trials are not necessarily predictive of final results. Preliminary and interim data are subject to the risk that one or more of the clinical outcomes reported may materially change as patient enrollment continues, more patient data become available, and we issue our final clinical trial report. Interim, topline and preliminary data also remain subject to audit and verification procedures that may result in the final outcomes or conclusions being materially different from those based on the preliminary data we previously published. As a result, preliminary, topline and interim data should be viewed with caution until the final analysis of the complete data set is available. Material adverse changes in the final data compared to the interim data could significantly harm our business prospects.

Our product candidates, including Nefecon, may have serious adverse, undesirable or unacceptable side effects which may delay or prevent marketing approval. If such side effects are identified during the development of one of our present or future product candidates or following approval we may need to abandon our development of such product candidate, the commercial profile of any approved label may be limited, or we may be subject to other significant negative consequences following marketing approval.

Undesirable side effects that may be caused by our product candidates, including Nefecon, could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, EC or other comparable foreign regulatory authorities. Budesonide, the active ingredient in Nefecon, is a corticosteroid, a class of drugs that is associated with high blood pressure, weight gain, diabetes, serious infections and osteoporosis. While budesonide has limited systemic availability due to high first pass metabolism and Nefecon is designed to leverage this inherent characteristic for local, rather than systemic effect, there can be no assurance we will avoid any or all of the side effects that may arise with corticosteroid treatment, whether local or systemic.

Although Nefecon has been generally well tolerated in previous clinical trials, the results from our ongoing or future trials may not replicate these observations. In our Phase 2b clinical trial of Nefecon, there were two drug-related serious adverse events, the first in a patient in the 16 mg treatment cohort who developed a deep venous thrombosis, which was classified by the investigator as possibly being treatment-related, and the second in a patient in the 8 mg treatment cohort who experienced aggravation of renal condition, which was classified by the investigator as possibly being treatment-related. In the placebo cohorts, three patients reported four serious adverse events (two events of proteinuria, sciatica and aggravated condition). Of these, two (proteinuria and aggravated condition) were classified by the investigator as possibly being treatment-related at the time when the safety results were blinded. We also observed adverse events that were generally consistent with those known to be associated with systemic corticosteroids like budesonide and a number of patient discontinuations due to mild to moderate adverse events, most frequently, acne and other transitory cosmetic side effects. In the full NefIgArd trial, we observed adverse events generally consistent with Part A; the most commonly reported TEAEs observed with an increased frequency compared to placebo were oedema peripheral, hypertension, muscle spasms and acne. The majority of TEAEs were of mild or moderate severity, and led to discontinuation of Nefecon in less than 10% of Nefecon-treated patients.

In completed studies of setanaxib (conducted in healthy volunteers or patients), the occurrence rates of TEAEs have been low and similar between setanaxib-treated and placebo-treated subjects. The most commonly reported TEAEs were headaches, upper respiratory tract infections, and common seasonal viral infections. These TEAEs occurred at similar rates in subjects treated with setanaxib in all dose groups and in subjects treated with placebo. The majority of TEAEs observed in subjects receiving setanaxib were mild or moderate in severity and transient. No treatment-related changes were observed in laboratory values, ECG evaluations, or vital signs. There have been no cases of allergy or hypersensitivity reactions.

There have been no fatal or life-threatening suspected unexpected serious adverse reactions (SUSARs) in the setanaxib clinical development program to date. The most commonly reported treatment-related serious adverse events (SAEs) were potential drug-induced liver injury (DILI) and hypothyroidism. It is important to note that these events have been reported from ongoing, blinded studies, so treatment attribution is not known. Hypothyroidism has only been reported in the ongoing study in head and neck cancer, and all five of the hypothyroidism events were considered to be related to pembrolizumab use (which all patients in the study receive). All four events of potential DILI have been reported in the ongoing study in PBC, where there is a potential confounding factor of the underlying disease, which may result in fluctuations in liver enzymes.

The results of any future clinical trials we conduct may show that our product candidates cause undesirable or unacceptable side effects. In such an event, our trials could be suspended, varied, or terminated and the FDA, the competent authorities of individual EU Member States, or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates or require postmarketing labeling changes for any or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and results of operations significantly.

Additionally, if Nefecon, setanaxib or any of our present or future product candidates receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by such products, a number of potentially significant negative consequences could result, including:

16

Table of Contents

regulatory authorities may suspend, vary, or withdraw approvals of such product and require us to take our approved product off the market;
regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field alerts to physicians and pharmacies;
regulatory authorities may require a medication guide outlining the risks of such side effects for distribution to patients, or that we implement a risk evaluation and mitigation strategy plan to ensure that the benefits of the product outweigh its risks;
we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product;
we may be subject to limitations on how we may promote the product;
sales of the product may decrease significantly;
we may be subject to litigation or product liability claims; and
our reputation may suffer.

Any of these events could prevent us, our collaborators or our potential future partners from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenue from the sale of our products.

We have and may in the future face challenges in enrollment of patients in our clinical trials given the relatively smaller patient population who have the diseases for which our product candidates are being developed. If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary marketing approvals could be delayed or prevented.

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA, the competent authorities of individual EU Member States or comparable foreign regulatory authorities. Patient enrollment is a significant factor in the timing of clinical trials. There can be no assurance that we will not experience enrollment challenges in future trials, particularly those for indications with relatively small patient populations. In addition, because we are initially focused on developing product candidates for orphan indications, we may encounter similar challenges for patient enrollment if and when we commence clinical programs for additional product candidates in the future.

Patient enrollment may be affected if our competitors have ongoing clinical trials for product candidates that are under development for the same indications as our product candidates, and patients who would otherwise be eligible for our clinical trial instead enroll in clinical trials of our competitors’ product candidates. Patient enrollment may also be affected by other factors, including:

size and nature of the patient population;
severity of the disease under investigation;
availability and efficacy of approved drugs for the disease under investigation;
patient eligibility and exclusion criteria for the trial in question;
patients’ and clinicians’ perceived risks and benefits of the product candidate under study;
competing clinical trials;

17

Table of Contents

efforts to facilitate timely enrollment in clinical trials;
patient referral practices of physicians;
the ability to monitor patients adequately during and after treatment;
proximity and availability of clinical trial sites for prospective patients; and
continued enrollment of prospective patients by clinical trial sites.

Our inability to enroll a sufficient number of patients for our clinical trials may result in significant delays or may require us to abandon such trial altogether. Even though we were able to enroll the planned number of patients in the NefIgArd clinical trial, there can be no assurance that we will successfully enroll the necessary number of patients in the TRANSFORM clinical trial or any additional clinical trials we may conduct. Enrollment into the TRANSFORM clinical trial was significantly slower than initially anticipated potentially due to the requirement for patients to have both elevated liver stiffness and elevated liver enzymes at the baseline assessment. Enrollment delays in our clinical trials may result in increased development costs for our product candidates, which would cause the value of our company to decline and limit our ability to obtain additional financing.

Changes in methods of product candidate formulation, manufacturing or testing may result in additional costs or delay.

As product candidates proceed through preclinical studies to late-stage clinical trials towards potential approval and commercialization, it is common that various aspects of the development program, such as formulation and manufacturing and testing methods, are altered along the way in an effort to optimize processes and results and comply with regulatory requirements or practices. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the materials manufactured using altered processes. Such changes may also require additional testing or notification to or approval by the FDA, the competent authorities of individual EU Member States, or comparable regulatory authorities. This could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability to commence sales and generate revenue. Product changes may also impact the scope of their intellectual property protection.

Nefecon and setanaxib have been granted orphan drug designation in a number of indications and we may seek orphan drug designation in other indications for future product candidates we develop. We may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation, including the potential for market exclusivity.

Nefecon has been granted orphan drug designation by the FDA, EC and MHRA for the treatment of IgAN and setanaxib has been granted orphan drug designation by the FDA and EC for the treatment of PBC, idiopathic pulmonary fibrosis and Alport syndrome. We may seek orphan drug designations for other indications and future product candidates. There can be no assurances that we will be able to obtain such designations.

Regulatory authorities in some jurisdictions, including the United States and the EU, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers.

18

Table of Contents

Similarly, in the EU, the EC grants orphan designation after receiving the opinion of the EMA Committee for Orphan Medicinal Products on an orphan designation application. Regulation (EC) No. 141/2000, as implemented by Regulation (EC) No. 847/2000 provides that a medicinal product can be designated as an orphan medicinal product by the EC if its sponsor can establish that: (1) the product is intended for the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions; (2) either (a) such conditions affect not more than 5 in 10,000 persons in the EU when the application is made, or (b) the product without the benefits derived from orphan status, would not generate sufficient return in the EU to justify the necessary investment in developing the medicinal product; and (3) there exists no satisfactory authorized method of diagnosis, prevention, or treatment of the condition that has been authorized in the EU, or even if such method exists, the product will be of significant benefit to those affected by that condition. Orphan medicinal product designation entitles an applicant to incentives such fee reductions or fee waivers, protocol assistance, and access to the centralized marketing authorization procedure.

Generally in the United States and the EU, if a drug with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which precludes the FDA or the EC, as applicable, from approving another marketing application for the same drug substance and indication in the United States or a similar drug for the same indication in the EU for that time period, except in limited circumstances. The applicable period is seven years in the United States and ten years in the EU. This ten-year period may be extended by two years for medicinal products in relation to which the marketing authorization holder has complied with a related agreed pediatric investigation plan. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications.

In the EU, the period of market exclusivity may, however, be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria on the basis of which it received orphan medicinal product destination, including where it can be demonstrated on the basis of available evidence that the original orphan medicinal product is sufficiently profitable not to justify maintenance of market exclusivity or where the prevalence of the condition has increased above the threshold. Additionally, a marketing authorization may be granted to a similar medicinal product with the same orphan indication during the 10 year period if: (i) if the applicant consents to a second original orphan medicinal product application, (ii) if the manufacturer of the original orphan medicinal product is unable to supply sufficient quantities; or (iii) if the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior to the original orphan medicinal product.

Orphan drug exclusivity may not effectively protect the product candidate from competition because different therapies can be approved for the same condition and the same therapies can be approved for different conditions but used off-label. Even after an orphan drug is approved, the FDA or comparable foreign regulatory authority can subsequently approve another drug for the same condition if the FDA or comparable foreign regulatory authority concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. In addition, a designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Moreover, orphan drug exclusive marketing rights in the United States may be lost if the FDA or comparable foreign regulatory authority later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. In the EU, the period of market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria on the basis of which it received orphan medicinal product destination, including where it can be demonstrated on the basis of available evidence that the original orphan medicinal product is sufficiently profitable not to justify maintenance of market exclusivity or where the prevalence of the condition has increased above the threshold. Additionally, a marketing authorization may be granted to a similar medicinal product with the same orphan indication during the 10 year period if: (i) if the applicant consents to a second original orphan medicinal product application; (ii) if the manufacturer of the original orphan medicinal product is unable to supply sufficient quantities; or (iii) if the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior to the original orphan medicinal product. A company may voluntarily remove a product from the register of orphan products.

Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. While we may seek orphan drug designation for other indications for our current and any future product candidates, we may never receive such designations. Further, even with respect to the indications for which we have received orphan designation, we may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated with developing pharmaceutical products, and thus, for example, approval of our product candidates could be blocked for seven years if another company previously obtained approval and orphan drug exclusivity in the United States for the same drug and same condition.

The target patient population of Nefecon for the treatment of IgAN is small and has not been definitively determined, and if the number of treatable patients for Nefecon or our present or future product candidates is lower than expected, our potential product sales revenues and our ability to achieve profitability would be compromised.

Our estimates of both the number of patients who have IgAN, as well as the subset of patients with this disease in a position to receive Nefecon, are based on our beliefs and estimates, and these estimates may prove to be incorrect. These estimates have been derived from a variety of sources, including scientific literature, input from physicians that treat patients with the diseases we are targeting, patient foundations and secondary market research databases. For example, our estimates of the prevalence of IgAN in certain geographies are based in part on the published prevalence of IgAN among patient populations in the United States split across ethnicities, and in part on our own analyses of prevalence in Europe, and on published disease incidence rates for certain geographies and estimated for the populations of such geographies. Further, new studies may change the estimated incidence or prevalence of IgAN, and any regulatory approvals that we may receive for Nefecon may include limitations for use or contraindications that decrease the addressable patient population. Accordingly, our target patient populations may turn out to be lower than expected, in which case the potential revenues from sales of Nefecon would be lower than expected.

We were not involved in the early development of setanaxib; therefore, we are dependent on third parties having properly conducted setanaxib’s preclinical research, manufacturing control and clinical development.

We had no involvement in or control over the preclinical and clinical development or manufacturing of setanaxib, which we acquired upon completion of our acquisition of Genkyotex S.A. We are dependent on third parties having conducted setanaxib research and development in accordance with legal, regulatory and scientific standards and the applicable protocols; having accurately reported the mode of action and results of all setanaxib preclinical studies and clinical trials; and having correctly collected and interpreted the data from these studies and trials. If these activities were not compliant, accurate or correct, the clinical development, regulatory approval or commercialization of setanaxib products, if pursued, could be adversely affected.

We face significant competition for our drug discovery, development and commercialization efforts, and if we do not compete effectively, our commercial opportunities will be reduced or eliminated.

The market for biopharmaceutical products is highly competitive. Our competitors include many established pharmaceutical companies, biotechnology companies, universities and other research or commercial institutions, many of which have substantially greater financial, research and development resources than us. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients and manufacturing pharmaceutical products. Smaller and early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, the development of our product candidates. The fields in which we operate are characterized by rapid technological change and innovation. See “Item 4.B.—Business Overview—Competition.”

We anticipate that we will continue to face intense and increasing competition as new treatments enter the market and advanced technologies become available. There can be no assurance that our competitors are not currently developing, or will not in the future develop, products that are equally or more effective or are more economically attractive than any of our current or future product candidates. Competing products may gain faster or greater market acceptance than our products and medical advances or rapid technological development by competitors may result in our product candidates becoming non-competitive or obsolete before we are able to recover our development and commercialization expenses. If we, our product candidates do not compete effectively, it may have a material adverse effect on our business, financial condition and results of operations.

Relevant regulatory exclusivities may not be granted or, if granted, may be limited.

The US, EU and UK provide opportunities for data and market exclusivity related to marketing authorizations. In the EU and UK, upon receiving a marketing authorization, innovative medicinal products are generally entitled to receive eight years of data exclusivity and 10 years of market exclusivity. Data exclusivity, if granted, prevents regulatory authorities in the EU and the UK from referencing the innovator’s data to assess a generic application or biosimilar application for eight years from the date of authorization of the innovative product, after which a generic or biosimilar marketing authorization application can be submitted, and the innovator’s data may be referenced. The market exclusivity period prevents a successful generic or biosimilar applicant from commercializing its product in the EU or UK until 10 years have elapsed from the initial marketing authorization of the reference product in the EU or UK. The overall ten-year period may, occasionally, be extended for a further year to a maximum of 11 years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. However, there is no guarantee that a product will be considered by the EU or UK regulatory authorities to be a new chemical/biological entity, and products may not qualify for data exclusivity.

In the US, market exclusivity can delay the submission or approval of certain marketing applications. The Federal Food, Drug and Cosmetic Act, or FDCA, provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to obtain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not approve or accept for review an abbreviated new drug application, or ANDA, or a Section 505(b) (2) NDA submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same indication as the original innovative drug or for another indication. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder. The FDCA also provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application. This three-year exclusivity covers only the conditions of use for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from accepting ANDAs or Section 505(b) (2) NDAs for drugs referencing the approved application for review.

If we fail to develop and commercialize other product candidates in addition to Nefecon, such as setanaxib, we may be unable to grow our business and our ability to achieve our strategic objectives would be impaired.

Although the development and commercialization of Nefecon for IgAN is our primary focus, we are currently evaluating setanaxib for the treatment of PBC, Alport syndrome, SCCHN and, through an investigator-led study, idiopathic pulmonary fibrosis. We also intend to evaluate additional potential indications for setanaxib, and we may choose to in-license or acquire other product candidates as well as commercial products to treat patients suffering from other diseases with significant unmet medical needs and limited treatment options, in particular orphan kidney and liver diseases.

Developing these other product candidates will require additional, time-consuming development efforts prior to commercial sale, including clinical trials and approval by the FDA, the EC and/or comparable foreign regulatory authorities. All present or future product candidates are prone to the risks of failure that are inherent in pharmaceutical product development, including the possibility that the product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities. In addition, we cannot assure that any such products that are approved will be manufactured or produced economically, successfully commercialized or widely accepted in the marketplace or be more effective than other commercially available alternatives. Our current strategy is to in-license or otherwise acquire product candidates for clinical development rather than discovering such candidates ourselves, and therefore our growth objectives are dependent on our ability to enter into in-licensing arrangements or acquisitions. For any such candidates for which we do not intend to conduct preclinical or early-stage clinical research, we may also become reliant on the research efforts of third parties. If we are unsuccessful in identifying and developing additional product candidates, our potential for growth and achieving our strategic objectives may be impaired.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and management resources, we focus on development programs and product candidates that we identify for specific indications. As such, we are currently primarily focused on completing development and continuing our commercialization of Nefecon and developing setanaxib, and we may forego or delay pursuit of opportunities with other product candidates or for other indications for Nefecon or our product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

We may be unable to successfully integrate new products or businesses we may acquire.

We may in the future expand our product pipeline by pursuing acquisition of new development programs, technology or product candidates. If an acquisition is consummated, the integration of the acquired business, product or other assets into our company may also be complex and time-consuming and, if such businesses, products and assets are not successfully integrated, we may not achieve the anticipated benefits, cost-savings or growth opportunities. Potential difficulties that may be encountered in the integration process include the following:

integrating personnel, operations and systems, while maintaining focus on developing and commercializing our existing product and product candidates;
coordinating geographically dispersed organizations;
distracting employees from operations; and
managing inefficiencies associated with integrating the operations of the acquired company or product into our own operations.

Furthermore, these acquisitions and other arrangements, even if successfully integrated, may fail to further our business strategy as anticipated, expose us to increased competition or challenges with respect to our products or geographic markets, and expose us to additional liabilities associated with an acquired business, product, technology or other asset or arrangement. Any one of these challenges or risks could impair our ability to realize any benefit from our acquisitions or arrangements after we have expended resources on them.

Even if our approved products or any future product candidate of ours receives regulatory approval, it may fail to achieve the degree of market acceptance among physicians, patients, third-party payors and the medical community necessary for commercial success.

Nefecon, which has received full approval in the US (under the brand name TARPEYO) and which has been granted conditional marketing authorization in the EU and the UK (under the brand name Kinpeygo), is our only approved product to date, but we and our commercialization partners may have other approved products in the future. These products and product candidates, if approved, may not achieve an adequate level of acceptance by physicians, patients, third-party payors and the medical community for commercial success. Despite the studies we have done on the IgAN commercial market opportunity and other pre-commercial activities that we have undertaken, there can be no assurance that we or our commercialization partners will be successful in marketing TARPEYO in the United States, Kinpeygo in the EU or the UK or, if approved, in other jurisdictions. In addition, efforts to educate the medical community and third-party payors on the benefits of Nefecon or other approved products may require significant resources and may not be successful or insufficiently successful to generate significant revenues or becoming profitable. While we believe that the US IgAN market could be adequately covered by a specialized salesforce of approximately 70 field representatives, we may underestimate the number of field representatives that we will actually require. While we believe physicians, patients and other members of the medical community may more readily accept and use Nefecon and our product candidates, if approved, as compared to entirely new chemical entities, Nefecon and our product candidates may nonetheless fail to gain sufficient market acceptance by physicians, patients, other healthcare providers and third-party payors. Market acceptance of our future products by physicians, patients and third-party payors will depend on a number of factors, many of which are beyond our control, including, but not limited to:

the clinical indications for which our existing or future product candidates are approved;
physicians, hospitals, treatment centers, and patients considering our existing or future product candidates as a safe and effective treatment;
the potential and perceived advantages of our product candidates over alternative treatments;
the prevalence and severity of any side effects;
product labeling or product insert requirements of the FDA, the EC or comparable foreign regulatory authorities;
limitations or warnings contained in the labeling approved by the FDA, the EC or comparable foreign regulatory authorities;
the timing of market introduction of our product candidates in relation to other potentially competitive products;
the cost of our product candidates in relation to alternative treatments;
the amount of upfront costs or training required for physicians to administer our product candidates;
the availability of coverage and adequate reimbursement from third-party payors and government; authorities;
the willingness of patients to pay out-of-pocket in the absence of comprehensive coverage and reimbursement by third-party payors and government authorities;
the relative convenience and ease of administration, including as compared to alternative treatments and competitive therapies;
the effectiveness of our sales and marketing efforts and distribution support; and
the presence or perceived risk of potential product liability claims.

Our efforts to educate physicians, patients, third-party payors and others in the medical community on the benefits and risks of our products, if approved, may require significant resources and may never be successful.

If our products fail to gain market acceptance, this will have a material adverse impact on our ability to generate revenues to provide a satisfactory, or any, return on our investments. Even if some products achieve market acceptance, the market may prove not to be large enough to allow us to generate significant revenues.

The successful commercialization of our products and present and future product candidates will depend in part on the extent to which governmental authorities and health insurers establish coverage and adequate reimbursement levels, as well as pricing policies. Failure to obtain or maintain adequate coverage and reimbursement for our product candidates, if approved, could limit our ability to market those products and decrease our ability to generate revenue.

The availability and adequacy of coverage and reimbursement by governmental healthcare programs such as Medicare and Medicaid in the US, comparable foreign programs, private health insurers and other third-party payors are essential for most patients to be able to afford Nefecon or any of our future product candidates, if approved. Our ability to achieve acceptable levels of coverage and reimbursement for our other products by governmental authorities, private health insurers and other organizations will have an effect on our ability to successfully commercialize and attract additional collaboration partners to invest in the development of, our product candidates, if approved. Assuming we obtain coverage for a given product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require patient out-of-pocket costs that patients find unacceptably high. We cannot be sure that coverage and reimbursement in the US, the EU or elsewhere will be available for any product that we may develop, and any reimbursement that may become available may be decreased or eliminated in the future.

Third-party payors increasingly are challenging prices charged for pharmaceutical products and services, and many third-party payors may refuse to provide coverage and reimbursement for particular drugs when an equivalent generic drug or a less expensive therapy is available or impose conditions or limitations on reimbursement, limiting the patient population that has access to the drugs. It is possible that a third-party payor may consider our products and other therapies as substitutable and only offer to reimburse patients for the less expensive product. Even if we show improved efficacy or improved convenience of administration with our products, pricing of existing drugs may limit the amount we will be able to charge for our products. These payors may deny or revoke the reimbursement status of a given drug product or establish prices for new or existing marketed products at levels that are too low to enable us to realize an appropriate return on our investment in product development. If reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize our product, and may not be able to obtain a satisfactory financial return on products that we may develop.

Government authorities and other third-party payors, such as private health insurers and health maintenance organizations, decide which drugs and treatments they will cover and the amount of reimbursement. Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that use of a product is:

a covered benefit under its health plan;
safe, effective and medically necessary;
appropriate for the specific patient;
cost-effective; and
neither experimental nor investigational.

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the US, third-party payors, including private and governmental payors, such as the Medicare and Medicaid programs, play an important role in determining the extent to which new drugs will be covered. The Medicare and Medicaid programs increasingly are used as models for how private payors and other governmental payors develop their coverage and reimbursement policies for drugs. Some third-party payors may require pre-approval or various pre-authorization steps for coverage for new or innovative drug therapies before they will reimburse health care providers who use such therapies. Increasingly, the third-party payors who reimburse patients or healthcare providers, such as government and private insurance plans, are seeking greater upfront discounts, additional rebates and other concessions to reduce the prices for therapeutics. If the price we are able to charge for any therapeutics we develop, the patient population we can successfully address, or the reimbursement provided for such therapeutics, is inadequate in light of our development and other costs, our return on investment could be adversely affected. It is difficult to predict at this time what third-party payors will decide with respect to the coverage and reimbursement for our product candidates.

Obtaining and maintaining reimbursement status is time-consuming and costly. No uniform policy for coverage and reimbursement for drug products exist among third-party payors in the US. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. Coverage policies and third-party payor reimbursement rates may change at any time. Therefore, even if favorable coverage and reimbursement status is attained, less favorable coverage policies and reimbursement rates may be implemented in the future. Furthermore, rules and regulations regarding reimbursement change frequently, in some cases at short notice, and we believe that changes in these rules and regulations are likely.

Outside the US, international operations are generally subject to extensive governmental price controls and other market regulations, and we believe the increasing emphasis on cost-containment initiatives in Europe, and other jurisdictions have and will continue to put pressure on the pricing and usage of our product candidates. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to fix their own prices for medical products but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates. Accordingly, in markets outside the US, the reimbursement for our products may be reduced compared with the US and may be insufficient to generate commercially reasonable revenue and profits.

The delivery of healthcare in the EU, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than EU, law and policy. National governments and health service providers have different priorities and approaches to the delivery of healthcare and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most EU Member States, have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Governments may support small scale pharmacy compounding (preparation of a drug in a pharmacy by a qualified pharmacist for an individual patient) of patented drugs as an alternative for expensive innovative drugs (forming a specific risk for orphan drugs with a small population) and may increasingly consider compulsory licensing of patented drugs to provide alternative options and control pharmaceutical prices. Coupled with EU and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to commercialize any products for which we obtain marketing approval.

Moreover, increasing efforts by governmental and third-party payors in the US, the EU and other jurisdictions to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product candidates. We may experience pricing pressures in connection with the sale of Nefecon or any of our product candidates that receive approval due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products, and government policies and efforts to contain costs could decrease the price we may receive for our approved products.

In addition, patients’ access to employer sponsored insurance coverage may be negatively impacted by economic factors that result in increased rates of unemployment. To the extent patients taking our current or future approved products become unemployed and experience a reduction to, or increased costs associated with, their insurance coverage, demand for our products could decline, which could have a material adverse effect on our sales and profitability, either as a result of decreased sales of our products and/or increased provision by us of free product to uninsured or commercially insured patients. The extent and duration of this potential impact on our business is currently unknown.

Recent federal legislation and actions by federal, state and local governments may permit reimportation of drugs from foreign countries into the US, including foreign countries where the drugs are sold at lower prices than in the US, which could materially adversely affect our operating results.

We may face competition in the US for our products and present or future product candidates, if approved, from therapies sourced from foreign countries that have placed price controls on pharmaceutical products.

In the US, the Medicare Modernization Act, or MMA, contains provisions that call for the promulgation of regulations that expand pharmacists’ and wholesalers’ ability to import cheaper versions of an approved drug and competing products from Canada, where there are government price controls. Further, the MMA provides that these changes to US importation laws will not take effect, unless and until the Secretary of the HHS certifies that the changes will pose no additional risk to the public’s health and safety and will result in a significant reduction in the cost of products to consumers. On September 23, 2020, the Secretary of the US Department of Health and Human Services, or HHS, made such certification to Congress, and on October 1, 2020, the FDA published a final rule that allows for the importation of certain prescription drugs from Canada. The FDA also issued additional guidance providing pathways for states to build and submit importation plans for drugs from Canada. Under the final rule, States and Indian Tribes, and in certain future circumstances pharmacists and wholesalers, may submit importation program proposals to the FDA for review and authorization. On September 25, 2020, CMS stated drugs imported by States under this rule will not be eligible for federal rebates under Section 1927 of the Social Security Act and manufacturers would not report these drugs for “best price” or Average Manufacturer Price purposes. Since these drugs are not considered covered outpatient drugs, CMS further stated it will not publish a National Average Drug Acquisition Cost for these drugs. Separately, the FDA also issued a final guidance document outlining a pathway for manufacturers to obtain an additional National Drug Code for an FDA-approved drug that was originally intended to be marketed in a foreign country and that was authorized for sale in that foreign country. On January 5, 2024, the FDA approved Florida’s Section 804 Importation Program (SIP) proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products covered by those programs.

Proponents of drug reimportation may attempt to pass legislation that would directly allow reimportation under certain circumstances, but Legislation, or regulation allowing the reimportation of drugs, if enacted, could decrease the price we receive for our products and adversely affect our future revenues and prospects for profitability.

We have only recently begun commercialization of the global Nefecon franchise and we have never previously commercialized a product. We may lack the necessary expertise, personnel and resources to successfully commercialize Nefecon or any other approved products on our own or together with suitable partners.

To achieve commercial success for any approved product, we must successfully develop or acquire a sales and marketing organization, outsource these functions to third parties or enter into partnerships. While we have built a sales and marketing infrastructure to commercialize TARPEYO, we did not previously have a sales and marketing infrastructure and have no prior experience in the sale or marketing of biopharmaceutical products. We have begun to commercialize TARPEYO in the United States independently, and first reported commercial availability of TARPEYO in January 2022.

There are risks involved in establishing our own sales and marketing capabilities. We may fail to continue to launch or market our products effectively, including launching in new jurisdictions in which Nefecon receives approval, because we have limited experience in the sales and marketing of biopharmaceutical products. In addition, recruiting and training a sales force is expensive and time consuming. Factors that may inhibit our efforts to commercialize our products on our own include:

our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;

26

Table of Contents

the inability of sales personnel to obtain access to or effectively educate adequate numbers of physicians to prescribe our products;
the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines;
reliance on third-party service providers for our field market access and reimbursement personnel and for the preparation of materials used in sales and market access materials;
unforeseen costs and expenses associated with recruiting, training, and retaining a sales and marketing organization; and
costs of marketing and promotion above those anticipated by us.

If we do not maintain sales and marketing capabilities successfully, we may not be successful in commercializing Nefecon and any other products that receive approval, which in turn would have a material adverse effect on our business, financial condition and results of operations.

Healthcare legislative reform measures may have a negative impact on our business and results of operations.

In the US and some foreign jurisdictions, there have been, and continue to be, legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell Nefecon and any product candidates for which we obtain marketing approval. Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements, (ii) additions or modifications to product labeling, (iii) the recall or discontinuation of our products or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect our business, financial condition and results of operations.

Among policy makers in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the US pharmaceutical industry. The ACA, among other things, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs, and creates a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

Since its enactment, there have been numerous judicial, administrative, executive, and legislative challenges to certain aspects of the ACA. On June 17, 2021, the US Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which, among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. Litigation and legislation related to the ACA are likely to continue, with unpredictable and uncertain results.

27

Table of Contents

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013, and due to subsequent legislative amendments to the statute, will remain in effect through 2032 unless additional Congressional action is taken. Additionally, on March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. The American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws and regulations may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.

There has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent US Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. At the federal level, in July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue to advance these principles. In addition, the IRA, among other things, (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs and biologics covered under Medicare Part B or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions take effect progressively starting in fiscal year 2023, although they may be subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. In response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the Centers for Medicare & Medicaid Services, (“CMS”), Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve the quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework. In addition, Congress has indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage bulk purchasing and importation from other countries, including Florida’s Section 804 Importation Program (“SIP”) proposal to import certain drugs from Canada for specific state healthcare programs.

We expect that these and other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved drug, which could have an adverse effect on customers for our product candidates. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.

On April 26, 2023, the EC adopted a proposal for a new Directive and Regulation to revise the existing pharmaceutical legislation. If adopted in the form proposed, the proposals to revise the existing EU laws governing authorization of medicinal products may result in a decrease in data and market exclusivity opportunities for our products in the EU and make them open to generic or biosimilar competition earlier than is currently the case with a related reduction in reimbursement status. In addition, many EU Member States periodically review their reimbursement procedures for medicinal products, which could have an adverse impact on reimbursement status. We expect that legislators, policymakers and healthcare insurance funds in the EU Member States will continue to propose and implement cost-containing measures, such as lower maximum prices, lower or lack of reimbursement coverage and incentives to use cheaper, usually generic, products as an alternative to branded products, and/or branded products available through parallel import to keep healthcare costs down. Moreover, in order to obtain reimbursement for our products in some European countries, including some EU Member States, we may be required to compile additional data comparing the cost-effectiveness of our products to other available therapies. Health Technology Assessment, or HTA, of medicinal products is becoming an increasingly common part of the pricing and reimbursement procedures In some EU Member States, including those representing the larger markets. The HTA process, which is currently governed by national laws in each EU Member State, is the procedure to assess therapeutic, economic and societal impact of a given medicinal product in the national healthcare systems of the individual country. The outcome of an HTA will often influence the pricing and reimbursement status granted to these medicinal products by the competent authorities of individual EU Member States. The extent to which pricing and reimbursement decisions are influenced by the HTA of the specific medicinal product currently varies between EU Member States.

On December 15, 2021, the Health Technology Regulation, or HTA Regulation, was adopted. The HTA Regulation is intended to boost cooperation among EU Member States in assessing health technologies, including new medicinal products, and providing the basis for cooperation at EU level for joint clinical assessments in these areas. When it enters into application in 2025, the HTA Regulation will be intended to harmonize the clinical benefit assessment of HTA across the EU. If we are unable to maintain favorable pricing and reimbursement status in EU Member States for product candidates that we may successfully develop and for which we may obtain regulatory approval, any anticipated revenue from and growth prospects for those products in the EU could be negatively affected.

Legislators, policymakers and healthcare insurance funds in the EU may continue to propose and implement cost-containing measures to keep healthcare costs down. These measures could include limitations on the prices we would be able to charge for product candidates that we may successfully develop and for which we may obtain regulatory approval or the level of reimbursement available for these products from governmental authorities or third-party payors. Further, an increasing number of EU and other foreign countries use prices for medicinal products established in other countries as “reference prices” to help determine the price of the product in their own territory. Consequently, a downward trend in prices of medicinal products in some countries could contribute to similar downward trends elsewhere.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action in the US or any other jurisdiction. There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect on anticipated revenue from Nefecon and other product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates.

The terms of approvals of our products and present or future product candidates and ongoing regulation of our products may limit how we manufacture and market our products, which could impair our ability to generate revenue.

Once regulatory approval has been granted, an approved product and its manufacturer and marketer are subject to ongoing review and extensive regulation.

We, and any future collaborators, must comply with requirements concerning advertising and promotion for Nefecon or any of our present or future product candidates, if approved. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved labeling. Thus, we and any future collaborators will not be able to promote Nefecon or any other products we develop for indications or uses for which they are not approved.

In addition, manufacturers of approved products and those manufacturers’ facilities are required to comply with extensive FDA or comparable foreign regulatory authority requirements, including ensuring that quality control and manufacturing procedures conform to current Good Manufacturing Practices, or cGMPs, which include requirements relating to quality control and quality assurance as well as the corresponding maintenance of records and documentation and reporting requirements. We, our contract manufacturers, any future collaborators and their contract manufacturers could be subject to periodic unannounced inspections by the FDA or other regulatory authorities, to monitor and ensure compliance with cGMPs. Despite our efforts to audit and verify regulatory compliance, one or more of our third-party manufacturing vendors may be found on regulatory inspection by the FDA or other comparable foreign regulatory authorities to be not in compliance with cGMP regulations, which may result in shutdown of the third-party vendor or invalidation of drug product lots or processes. In some cases, a product recall may be warranted or required, which would materially affect our ability to supply and market our drug products.

The marketing authorization holder is subject to extensive regulations in relation to the safety monitoring of its marketed products including good vigilance practices, or GVP, and will be subject to monitoring by the FDA, EMA, competent authorities of individual EU Member States, and other comparable foreign regulatory authorities involving inspections of pharmacovigilance systems. Non-compliance with GVP can result in inspection follow-up, actions on the marketing authorization (such as suspensions or restrictions), as well as administrative penalties and civil or criminal liabilities.

Failure to comply with US, EU, and other laws that apply to the conduct of clinical trials, manufacturing approval, marketing authorization of medicinal products and marketing of such products, both before and after grant of the marketing authorization, or with other applicable regulatory requirements may result in administrative, civil or criminal penalties. These penalties could include delays or refusal to authorize the conduct of clinical trials, or to grant marketing authorization, product withdrawals and recalls, product seizures, suspension, withdrawal or variation of the marketing authorization, total or partial suspension of production, distribution, manufacturing or clinical trials, operating restrictions, injunctions, suspension of licenses, fines and criminal penalties.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action in the US or any other jurisdiction.

Accordingly, assuming we, or any future collaborators, receive regulatory approval for one or more of our product candidates, we, and any future collaborators, and our and their contract manufacturers will continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance and quality control.

If we, and any future collaborators, are not able to comply with post-approval regulatory requirements, we, and any future collaborators, could have the regulatory approvals for our products varied, suspended, or withdrawn by regulatory authorities and our, or any future collaborators’, ability to market any future products could be limited, which could adversely affect our ability to achieve or sustain profitability. Failure to comply with any related obligations may also result in civil and/or criminal penalties. Further, the cost of compliance with post-approval regulations may have a negative effect on our operating results and financial condition.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not mean that we will be successful in obtaining marketing approval of our current and future product candidates in other jurisdictions.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain marketing approval in any other jurisdiction, while a failure or delay in obtaining marketing approval in one jurisdiction may have a negative effect on the marketing approval process in others. For example, the fact that we have received full approval for TARPEYO in the United States does not guarantee that we or our commercialization partners will receive full approval in other jurisdictions such as in the EU and UK. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the US, including additional preclinical studies or clinical trials as clinical studies conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the US, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

We may become exposed to costly and damaging liability claims, either when testing our product candidates in the clinic or at the commercial stage; and our product liability insurance may not cover all damages from such claims.

We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing and use of pharmaceutical products. The current and future use of our products or product candidates by us and our collaborators in clinical trials, and the sale of any approved products in the future, may expose us to liability claims. These claims might be made by patients who use the product, healthcare providers, our collaborators or others selling such products. Any claims against us, regardless of their merit, could be difficult and costly to defend and could materially adversely affect the market for our product candidates or any prospects for commercialization of our product candidates. Although the clinical trial process is designed to identify and assess potential side effects, it is always possible that a product, even after regulatory approval, may exhibit unforeseen side effects. If any of our products or product candidates were to cause adverse side effects during clinical trials or after approval of the product candidate, we may be exposed to substantial liabilities. Physicians and patients may not comply with any warnings that identify known potential adverse effects and patients who should not use our product candidates. Regardless of the merits or eventual outcome, liability claims may result in:

decreased demand for our products due to negative public perception;
injury to our reputation;
withdrawal of clinical trial participants or difficulties in recruiting new trial participants;
initiation of investigations by regulators;
costs to defend or settle the related litigation;
a diversion of management’s time and our resources;
substantial monetary awards to trial participants or patients;
product recalls, withdrawals or labeling, marketing or promotional restrictions;
loss of revenues from product sales; and
the inability to commercialize any of our product candidates, if approved.

Although we believe we maintain adequate product liability insurance for our product candidates, it is possible that our liabilities could exceed our insurance coverage. We have expanded our insurance coverage to include our sale of our approved products. However, we may not be able to maintain insurance coverage at a reasonable cost and we may not obtain insurance coverage that will cover claims arising from the activities of our commercial partners or be adequate to satisfy any liability that may arise. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to cover such claims and our business operations could be impaired.

Should any of the events described above occur, this could have a material adverse effect on our business, financial condition and results of operations.

Off-label use or misuse of our products may harm our reputation in the marketplace or result in injuries that lead to costly product liability suits.

We may only promote or market our approved products for their specifically approved indications. TARPEYO received full approval by the FDA to reduce the loss of kidney function in adults with primary IgAN. Kinpeygo currently has conditional approval by the EC and the MHRA only for the treatment of primary (IgAN in adults at risk of rapid disease progression with a UPCR ≥1.5 gram/gram. In China, Macao and Singapore, Nefecon (under the name NEFEGAN in Singapore) has conditional approval for the treatment of primary IgAN in adults at risk of rapid disease progression, generally with a UPCR ≥1.5 gram/gram. We have trained and will continue to train our marketing and sales force against promoting TARPEYO, or any product candidate approved in the future for uses outside of the approved indications for use, known as “off-label uses.” We cannot, however, prevent a physician from using our products off-label, when in the physician’s independent professional medical judgment he or she deems it appropriate. Furthermore, the use of our products for indications other than those approved by the FDA, the EC or comparable foreign regulatory authorities may not effectively treat such conditions, and may increase the adverse events when compared to use for its approved indication. Any such off-label use could harm our reputation in the marketplace among physicians and patients. There may also be increased risk of injury to patients if physicians attempt to use our products for these uses for which they are not approved, which could lead to product liability suits that that might require significant financial and management resources and that could harm our reputation.

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred significant losses since our inception and anticipate that we will continue to incur operating losses for the near future.

We are a commercial-stage pharmaceutical company with a limited operating history and only one recently approved product. Since our inception, we have incurred significant operating losses. We incurred total comprehensive losses of SEK 483.8 million and SEK 373.2 million for the years ended December 31, 2023 and December 31, 2022, respectively. As of December 31, 2023, we had an accumulated loss of SEK 2,305.6 million. Our losses resulted principally from costs incurred in clinical development of Nefecon and setanaxib, cost for sales and marketing activities in the US and from administrative costs associated with our operations. Any operating losses we incur, among other things, will cause our working capital and shareholders’ equity to decrease. We anticipate that our expenses will increase if and as we:

continue to develop and advance Nefecon, setanaxib and any other product candidates;
initiate and continue clinical development for Nefecon and setanaxib for PBC, head and neck cancer, Alport syndrome and other potential indications;
support our partners in pursuing regulatory approval for Nefecon in various jurisdictions;
seek regulatory approval for setanaxib and any other present and future product candidates that successfully complete clinical trials;
continue to build a sales, marketing and distribution infrastructure and scale-up external manufacturing to commercialize Nefecon and any other present or future product candidates that receive approval;
maintain, expand and protect our intellectual property portfolio, including litigation costs associated with defending against alleged patent infringement or invalidity claims and enforcing patents against third parties;
continue to add clinical, scientific, operational, financial and management information systems and personnel, including personnel to support our product development and commercialization efforts;
seek to expand development pipeline, including through potential in-licensing opportunities and strategic acquisitions;
expand our operations in the United States and Europe; and

32

Table of Contents

experience any delays or encounter any issues with regards to any of the above, including, but not limited to, failed studies, ambiguous trial results, safety issues or other regulatory challenges, including any unforeseen costs we may incur as a result of clinical trial or supply chain delays or other business interruptions due to health pandemics, geopolitical tensions or other world events.

To date, we have funded our operations through public and private placements of equity securities, proceeds from credit facilities, upfront and milestone payments and interest income from the investment of our cash and financial assets. We have also begun to fund our operations with the proceeds from sales of TARPEYO in the United States and royalties from the sales by our commercialization partners in the EU and China.

To become and remain profitable, we must succeed in developing and commercializing products and product candidates that generate significant revenue. This will require that we and our commercialization partners be successful in a range of challenging activities, including in-licensing and developing additional product candidates, obtaining regulatory approval for any product candidates that successfully complete clinical trials, including full regulatory approval for Kinpeygo in the EU and UK and for Nefecon in various jurisdictions, establishing marketing capabilities and ultimately selling any products which are approved. We are only in the preliminary stages of many of these activities. We may never succeed in these activities and, even if we do, may never generate revenue that is significant enough to achieve or maintain profitability. We anticipate incurring significant costs associated with commercializing our approved products. Our expenses could increase beyond our current expectations if we are required by the FDA, the EMA or comparable foreign regulatory authorities to perform clinical trials or studies in addition to those that we currently anticipate, including as a result of any post-approval commitments or trial requirements. Even though we have begun to generate revenue from the sale of approved products, we may not become profitable and may need to obtain additional funding to continue operations.

Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our common shares and American Depositary Shares (“ADSs”) and could impair our ability to raise capital, expand our business, maintain our research and development efforts or continue our operations. A decline in the value of our common shares or ADSs could also cause you to lose all or part of your investment.

We may need substantial additional funding in order to fund our operations. Failure to obtain this necessary capital at acceptable terms and when needed may force us to delay, limit or terminate certain or all of our operations and pursuit of our growth strategy.

Our operations have consumed substantial amounts of cash since inception. Unless and until we are able to successfully commercialize Nefecon and achieve significant revenue from sales, we will require substantial additional funding in the future to sufficiently finance our operations and advance the clinical development, seek regulatory approval for and potentially commercialize our approved products or product candidates, or potentially acquire or in-license additional product candidates.

As of December 31, 2023, we had SEK 973.7 million in cash. Based on our current operating plan, we expect that our existing cash will be sufficient to fund our planned operations and capital expenditure requirements until we become profitable, subject to continued revenue growth of the Nefecon franchise. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect and we may not achieve profitability on the timeline we expect or ever. Our future capital requirements will depend on many factors, including:

the initiation, progress, timing, costs and results of clinical trials for Nefecon, setanaxib and future product candidates;
the number of potential new product candidates and indications we identify and decide to develop, if any;
the time and costs involved in obtaining regulatory approval for Nefecon and any of our product candidates that successfully complete clinical development, and any delays we may encounter as a result of evolving regulatory requirements or adverse clinical trial results with respect to any of our product candidates;
the extent to which we develop, in-license or acquire other product candidates and technologies;
the costs involved in growing our organization to the size needed to allow for the development and commercialization of Nefecon and any future approved products;

33

Table of Contents

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending against any invalidity or infringement claims raised by third parties;
the costs related to our obligations under our existing collaboration and licensing agreements and the entry into new collaboration and licensing agreements;
the cost and timing of future pre-commercialization activities and, with respect to any products that receive regulatory approval, post-commercialization activities, and costs involved in maintaining and, if necessary, expanding an effective sales and marketing organization;
the revenue we receive either directly from commercial sales or in the form of royalty, upfront or milestone payments from future sales of Nefecon or future product candidates, if approved;
the cost and timing of completion of commercial-scale manufacturing activities;
the effects of competing technological and market developments; and
the costs of operating as a public company in both the United States and Sweden.

Until we can generate sufficient product revenue to finance our cash requirements, which we may never do, we expect to finance our future cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements.

Our ability to raise additional funds will depend on financial, economic and market conditions and other factors, over which we may have no or limited control. Market volatility resulting from pandemics, global armed conflicts, financial market disruption or other factors could also adversely impact our ability to access capital as necessary. If adequate funds are not available on commercially acceptable terms when needed, we may be forced to delay, reduce or terminate the development or commercialization of all or some of our product candidates or research programs or we may be unable to take advantage of future business opportunities.

Raising additional capital may cause dilution to holders of our common shares or ADSs, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Other than our term loan facility (the “Credit Agreement”) with Athyrium Capital Management, LP (“Athyrium”), we do not have any committed external source of funds or other support for our development efforts and we cannot be certain that additional external funding will be available on acceptable terms, or at all. Until we can generate substantial product revenues from sales of Nefecon or other approved products, if any, we expect to finance our operations predominantly through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements.

Table of Contents

Under the Credit Agreement, Athyrium made available to us 92 million Euros, which we fully drew down. We used part of the proceeds from the Credit Agreement to repay in full outstanding obligations under our loan agreement with Kreos Capital VI (UK) Limited and Kreos Capital 2020 Opportunity (UK) Limited. The Credit Agreement contains financial covenants to maintain minimum unrestricted cash (including cash equivalents) and achieve minimum net revenue targets with respect to Nefecon. The Credit Agreement contains affirmative and negative covenants customary for a senior secured loan. The negative covenants under the Credit Agreement limit the ability of us and our subsidiaries to, among other things, dispose of assets, engage in certain mergers, acquisitions, and similar transactions, incur additional indebtedness, grant liens, make investments, pay dividends or make distributions or certain other restricted payments in respect of equity, prepay other indebtedness, enter into restrictive agreements, undertake fundamental changes or amend certain material contracts, in each case subject to certain exceptions. The Credit Agreement also contains certain customary events of default, including, but not limited to, a failure to comply with the covenants in the Credit Agreement. If an event of default has occurred and continues beyond any applicable cure period, the administrative agent or the required lenders may accelerate all outstanding obligations under the Credit Agreement and/or exercise any other remedies provided under the loan documents. See Item 5.B., Liquidity and Capital Resources, for more details on the Credit Agreement.

If we undertake additional financing arrangements in the future, the terms of any such financing may adversely affect the holdings or the rights of holders of our common shares or ADSs and the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our common shares or ADSs to decline. The sale of additional equity or convertible securities would dilute all of our existing shareholders and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a holder of ADSs. The incurrence of indebtedness could result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. We could also be required to seek funds through arrangements with collaborators or others at an earlier stage than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, financial condition and results of operations. Further, any additional fundraising efforts may divert our management from its day-to-day activities, which may adversely affect our ability to develop and commercialize Nefecon and our product candidates.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of our development programs or the commercialization of Nefecon or any of our product candidates, if approved, or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially affect our business, financial condition and results of operations.

We have a limited operating history as a commercial company, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We began operations in 2004. Prior to our commercialization of TARPEYO, with commercial availability which began in January 2022, we had not obtained marketing approvals for any product candidates, manufactured products on a commercial scale, or arranged for a third party to do so on our behalf, or conducted sales and marketing activities necessary for successful commercialization. Consequently, predictions about our future success or viability may not be as accurate as they could be if we had a longer history of successfully developing and commercializing products. Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate activity or an acceptable safety profile, gain regulatory approval, secure market access and reimbursement and become commercially viable.

Given our limited operating history as a commercial company, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors in achieving our business objectives. Our financial condition and operating results may continue to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. We have transitioned from a company with solely a research and development focus to a company also capable of undertaking commercial activities. We may encounter unforeseen expenses, difficulties, complications and delays, and may not be successful in such a transition.

Risks Related to Our Dependence on Third Parties

We rely, and expect to continue to rely, on third parties, including independent clinical investigators and contract research organizations, or CROs, to conduct our clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.

We have relied upon, and plan to continue to rely upon third parties, including independent clinical investigators and third-party CROs, to conduct our clinical trials and to monitor and manage data for our clinical programs. We rely on these parties for execution of our clinical trials, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our trials is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on these third parties does not relieve us of our regulatory responsibilities. We and our third-party contractors and CROs are required to comply with GCP requirements, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for all of our products in clinical development. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we, our investigators or any of our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, the EC, the EMA, or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.

Further, these investigators and CROs are not our employees and we will not be able to control, other than by contract, the amount of resources, including time, which they devote to our product candidates and clinical trials. If independent investigators or CROs fail to devote sufficient resources to the development of our product candidates, or if their performance is substandard or not in conformity with our clinical trial protocols or GCP regulations, it may delay or compromise the prospects for approval and commercialization of any product candidates that we develop. In addition, the use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this information will be misappropriated.

Our CROs have the right to terminate their agreements with us in the event of an uncured material breach. In addition, some of our CROs have an ability to terminate their respective agreements with us if it can be reasonably demonstrated that the safety of the subjects participating in our clinical trials warrants such termination, if we make a general assignment for the benefit of our creditors or if we are liquidated.

Although we are not currently conducting any clinical trials in Ukraine, the Russia-Ukraine military conflict could cause disruption in the region which could affect our CRO’s operations, which in turn could impact our own clinical trials.

There is a limited number of third-party service providers that specialize or have the expertise required to achieve our business objectives. If any of our relationships with these third-party CROs or clinical investigators terminate, we may not be able to enter into arrangements with alternative CROs or investigators or to do so on commercially reasonable terms. If CROs or clinical investigators do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they cannot perform their contractual duties or obligations due to the impacts of the geopolitical tensions on their operations or at the sites they are overseeing, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.

Switching or adding additional CROs or investigators involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and results of operations.

36

Table of Contents

In addition, clinical investigators may serve as scientific advisors or consultants to us from time to time and may receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or the FDA or a comparable foreign regulatory authority concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated at the applicable clinical trial site may be questioned and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection by the FDA or a comparable foreign regulatory authority. Any such delay or rejection could prevent us from commercializing our clinical-stage product candidates or any future product candidates.

We are dependent on third parties to manufacture and distribute our products.

We have no manufacturing capabilities and rely on third-party manufacturers who are sole source suppliers for manufacturing of Nefecon. If our third-party manufacturers are unable to meet our demand, our ability to commercialize our products will be adversely impacted and could affect our ability to gain market acceptance for our products and negatively impact our revenues. Our dependence on third parties for the manufacture of our products may harm our profit margin on the sale of Nefecon and our ability to deliver Nefecon on a timely and competitive basis. Because we are ultimately responsible for ensuring supply of Nefecon to the market, it is critical that we maintain effective management practices and oversight with respect to our third-party manufacturers, including supply chain management.

We currently have no in-house distribution channels for Nefecon and we are dependent on third-party distributors to distribute such products. The outsourcing of our distribution function is complex, and we may experience difficulties that could reduce, delay or stop shipments of such products. If we encounter such distribution problems, and we are unable to quickly enter into a similar agreement with another distributor on substantially similar terms, distribution of Nefecon could become disrupted, resulting in lost revenues, provider dissatisfaction, and/or patient dissatisfaction.

Use of third parties to manufacture our products and product candidates may increase the risk that we will not have sufficient quantities of our product and product candidates or such quantities at an acceptable cost, and clinical development and commercialization of our product and product candidates could be delayed, prevented or impaired.

We do not own or operate manufacturing facilities for clinical or commercial production of our products or product candidates. We have limited personnel with experience in drug manufacturing and we lack the resources and the capabilities to manufacture any of our product candidates on a clinical or commercial scale. We outsource all manufacturing and packaging of our nonclinical, clinical, and commercial products to third parties. The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of pharmaceutical products often encounter difficulties in production, particularly in scaling up initial production and in maintaining required quality control. These problems include difficulties with production costs and yields and quality control, including stability of the product candidate.

We intend to rely on third-party manufacturers for the long-term commercial supply of Nefecon and for our development stage product candidates. We have a single CMO for each of Nefecon and setanaxib. We face risks inherent in relying on a single CMO, as any disruption, such as a fire, natural hazards, pandemic, epidemic, or outbreak of an infectious disease or vandalism at the CMO could significantly interrupt our manufacturing capability. We currently do not have alternative production plans in place or disaster-recovery facilities available. In case of a disruption, we will have to establish alternative manufacturing sources. This would require substantial capital on our part, which we may not be able to obtain on commercially acceptable terms or at all. Additionally, we would likely experience months of manufacturing delays as we build or locate replacement facilities and seek and obtain necessary regulatory approvals. If this occurs, we will be unable to satisfy manufacturing needs on a timely basis, if at all. Also, operating any new facilities may be more expensive than operating our current facility. Further, business interruption insurance may not adequately compensate us for any losses that may occur and we would have to bear the additional cost of any disruption. For these reasons, a significant disruptive event of the manufacturing facility could have drastic consequences, including placing our financial stability at risk.

Reliance on third-party manufacturers entails risks to which we may not be subject if we manufactured our product candidates or products ourselves, including:

reliance on the third party for regulatory compliance and quality assurance;

37

Table of Contents

limitations on supply availability resulting from capacity and scheduling constraints of the third parties;
less control over cost increases resulting from inflationary pressures affecting raw materials and other supply chain components;
impact on our reputation in the marketplace if manufacturers of our products fail to meet the demands of our customers;
the possible breach of the manufacturing agreement by the third party because of factors beyond our control; and
the possible termination or nonrenewal of the agreement by the third party, based on its own business priorities, at a time that is costly or inconvenient for us.

The failure of any of our contract manufacturers to maintain high manufacturing standards could result in injury or death of clinical trial participants or patients using our products. Such failure could also result in product liability claims, product recalls, product seizures or withdrawals, delays or failures in testing or delivery, cost overruns or other problems that could seriously harm our business or profitability.

Our contract manufacturers are required to adhere to FDA regulations setting forth cGMP and comparable foreign regulatory authority requirements. These regulations cover all aspects of the manufacturing, testing, quality control and recordkeeping relating to our product candidates and any products that we may commercialize. Our manufacturers may not be able to comply with cGMP regulations or similar regulatory requirements outside the United States. Our manufacturers are subject to unannounced inspections by the FDA, state regulators and similar regulators outside the United States to monitor and ensure compliance with cGMP. We are ultimately responsible for ensuring that our API and finished products are manufactured in accordance with cGMP regulations and similar regulatory requirements outside the United States, and it is therefore critical that we maintain effective management practices and oversight with respect to our third-party manufacturers, including routine auditing. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including shutdown of the third-party vendor or invalidation of drug product lots or processes, fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approval of our product candidates, delays, suspension, variation or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect regulatory approval and supplies of our product candidates.

Our product and any products that we may develop may compete with other product candidates and products for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations and that are both capable of manufacturing for us and willing to do so. A health epidemic or pandemic and associated vaccine or treatment development and manufacturing efforts may increase demand for the services supplied by many third-party manufacturers, including some of those that we utilize for our products and product candidates, which may result in decreased availability of manufacturing slots at many such facilities. If the third parties that we engage to manufacture products for our developmental or commercial products should halt or cease to continue to do so for any reason, we likely would experience interruptions in cash flows and/or delays in advancing our clinical trials while we identify and qualify replacement suppliers, and we may be unable to obtain replacement supplies on terms that are favorable to us. Later relocation to another manufacturer will also require notification, review and other regulatory approvals from the FDA and other regulators and will subject our production to further cost and instability in the availability of our product candidates. In addition, if we are not able to obtain adequate supplies of our products and product candidates, or the drug substances used to manufacture them, it will be more difficult for us to sell our products and to develop our product candidates. This could greatly reduce our competitiveness and negatively affect our results of operations.

Our current and anticipated future dependence upon others for the manufacture of our products and product candidates may adversely affect our future profit margins and our ability to develop product candidates and commercialize our marketed products and any other products that may obtain regulatory approval on a timely and competitive basis.

38

Table of Contents

Materials necessary to manufacture our products and product candidates may not be available on commercially reasonable terms, or at all, which may delay the development and commercialization of our products and product candidates.

We rely on the manufacturers of our products and product candidates to purchase from third-party suppliers the materials necessary to produce the compounds for our nonclinical and clinical studies and rely on these other manufacturers for commercial distribution if we obtain marketing approval for any of our product candidates. Suppliers may not sell these materials to our manufacturers at the time we need them or on commercially reasonable terms and all such prices are susceptible to fluctuations in price and availability due to transportation costs, government regulations, price controls, and changes in economic climate or other foreseen circumstances. We do not have any control over the process or timing of the acquisition of these materials by our manufacturers. In addition, inflation and global supply chain disruptions, as well as past disruptions related to COVID-19 and potential future disruptions related to a future health epidemic or pandemic, wars, armed conflicts, and global geopolitical tension, including between the U.S. and China, have had and may continue to have a negative impact on our manufacturers’ ability to acquire the materials necessary for our business. Moreover, we currently do not have any agreements for the commercial production of these materials. If our manufacturers are unable to obtain these materials for our nonclinical and clinical studies, product testing and potential regulatory approval of our product candidates would be delayed, significantly impacting our ability to develop our product candidates. If our manufacturers or we are unable to purchase these materials after regulatory approval has been obtained for our product candidates, the commercial launch of our product candidates would be delayed or there would be a shortage in supply, which would materially affect our ability to generate revenues from the sale of our product candidates.

We have entered into agreements with third parties to develop and commercialize Nefecon in jurisdictions outside the United States, if approved in such jurisdictions, and we plan to enter into additional agreements in the future with respect to any of our present or future product candidates that receive approval. If we are unable to establish and maintain such collaborations, we may not be successful in our commercialization efforts. If our commercialization partners do not to satisfy their obligations or are unsuccessful, we could be adversely affected.

We have arrangements with third parties to commercialize our products in territories outside of the US and may enter into additional agreements in the future. As a result, our product revenues or the profitability of these product revenues to us could be lower than if we were to market and sell the products that we develop ourselves. Such collaborative arrangements may result in the commercialization of our products being out of our control and would subject us to a number of risks including that we may not be able to control such as the amount or timing of resources that our commercialization partner devotes to our products and that our partner’s willingness or ability to optimally commercialize our products may be adversely affected by business combinations or significant changes in our collaborator’s business strategy. In addition, we may not be successful in entering into arrangements with additional third parties to sell and market our products or may be unable to do so on terms that are favorable to us. Acceptable third parties may fail to devote the necessary resources and attention to sell and market our products effectively.

Outside of the US, we intend to commercialize Nefecon through either regional partnerships or on a country-by-country basis. In Europe, we have entered into a commercialization agreement with STADA to commercialize Nefecon (approved under the name Kinpeygo) in the EU and the UK. STADA will also commercialize Nefecon in Switzerland, if approved in that jurisdiction. We have transferred the conditional marketing authorizations received from the EC and the MHRA to STADA. STADA has submitted requests to both the EMA and to the MHRA to convert the current conditional marketing authorizations for these territories into full marketing authorizations. In 2019, we granted a license to Everest, to develop and commercialize Nefecon for the treatment of IgAN and other potential indications in Greater China and Singapore and in March 2022, we expanded the territory covered by the agreement to include the Republic of Korea. We have also entered into a commercialization agreement with Viatris Pharmaceuticals Japan Inc., a subsidiary of Viatris Inc., or Viatris, to commercialize Nefecon for the treatment of IgAN in Japan.

Our existing collaborations and any future collaborations that we enter into may not be successful. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Collaborations are subject to numerous risks, including, for example, that the collaborators may not: adequately perform their obligations under the collaboration agreement; devote sufficient resources to the collaboration to ensure success; or agree with us on the strategy or tactical aspects of the collaboration.

To the extent that we depend on collaborators for sales and marketing activities, any revenues we receive will depend upon the success of those collaborators’ sales and marketing teams and the collaborators’ prioritization of our product and compliance with applicable regulatory requirements, and there can be no assurance that the collaborators’ efforts will be successful or that their compliance systems will be effective. If any existing or future collaborations do not result in the successful development and commercialization of product candidates, or if one of our collaborators terminates its agreement with us, we may not receive any future milestone or royalty payments under the collaboration. If we do not receive the funding we expect under these agreements, the development of our product candidates could be delayed and we may need additional resources to develop our product candidates. In addition, if one of our collaborators terminates its agreement with us, we may find it more difficult to attract new collaborators and the perception of us in the business and financial communities could be adversely affected. All of the risks relating to our product development, regulatory activities and commercialization apply to the activities of our existing and future collaborators.

If we are unable to enter into a collaboration for the commercialization of product candidates we develop, if approved, we may be forced to delay the commercialization of our product candidates or reduce the scope of our sales or marketing activities in such jurisdictions, which would have an adverse effect on our business, operating results and prospects.

In foreign countries, the pricing of drugs is generally subject to governmental control and other market regulations which could put pressure on the pricing and usage of our products and present or future product candidates. In these countries, pricing negotiations with governmental authorities can take considerable time after obtaining marketing approval of a product candidate. In addition, market acceptance and sales of our products and product candidates will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our product candidates and may be affected by existing and future healthcare reform measures. We will be dependent on the abilities and efforts of our commercialization partners to obtain optimal pricing and reimbursement status for our products and product candidates and, should our commercialization partners fail to do so, the amounts paid to us by commercialization partners and the value of our products could be adversely impacted.

Jurisdictions outside of the United States generally also have laws, regulations, or industry or professional codes of conduct concerning the provision of benefits or advantages to health care providers to prevent inducement or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products, anti-bribery laws, laws requiring the disclosure of benefits provided to healthcare professionals, healthcare organizations or patient organizations, or laws requiring prior notification and approval by the a health care provider’s employer, his or her competent professional organization and/or regulatory authorities. Should our commercialization partners fail to comply with these requirements, they could be subject to reputational risk, public reprimands, administrative penalties, fines or imprisonment, and the amounts paid to us by our commercialization partners and the value of products could be adversely impacted.

If our third-party providers, including our CMOs and CROs, fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could harm our business.

Our third-party manufacturers are subject to numerous environmental, health and safety laws and regulations, including those governing the handling, use, storage, treatment and disposal of hazardous materials and wastes. Although we believe that the safety procedures utilized by our third-party manufacturers for handling and disposing of these materials generally comply with the standards prescribed by these laws and regulations, we cannot guarantee that this is the case or eliminate the risk of accidental contamination or injury from these materials. In such an event, we may be held liable for any resulting damages and such liability could exceed our resources and state or federal or other applicable authorities may curtail our use of certain materials and/or interrupt our business operations.

Furthermore, environmental laws and regulations are complex, change frequently and have tended to become more stringent. We cannot predict the impact of such changes and cannot be certain of our future compliance. In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

Table of Contents

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries resulting from the use of hazardous materials or other work-related injuries, this insurance may not provide adequate coverage against potential liabilities. We do not carry specific biological waste or hazardous waste insurance coverage, workers compensation or property and casualty and general liability insurance policies that include coverage for damages and fines arising from biological or hazardous waste exposure or contamination.

Risks Related to Intellectual Property

We rely on patents and other intellectual property rights to protect Nefecon, setanaxib and our other product candidates, the enforcement, defense and maintenance of which may be challenging and costly. Failure to enforce or protect these rights adequately could harm our ability to compete and impair our business.

Our commercial success depends in part on obtaining and maintaining patents and other forms of intellectual property rights for Nefecon, setanaxib and our other present and future product candidates, methods used to manufacture those products and the methods for treating patients using those products, or on licensing in such rights. Patent law relating to the scope of claims in the fields in which we operate is complex and uncertain, and we cannot make any assurances that we will be able to obtain or maintain patent or other intellectual property rights, or that the patent and other intellectual property rights we may obtain will be valuable, provide an effective barrier to competitors or otherwise provide competitive advantages. For example, although we co-own a single patent family relating to the formulation of Nefecon, which expires in 2029, such rights may not provide adequate protection against competitors. In January 2024, the United States Patent and Trademark Office, or USPTO, issued a new patent to us relating to the method of treating IgA nephropathy which expires in 2043; such rights may not provide adequate protection against competitors. Failure to protect or to obtain, maintain or extend adequate patent and other intellectual property rights could materially adversely affect our ability to develop and market our products and product candidates. Patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from such applications, and then only to the extent the issued claims cover the technology at issue. We cannot be certain that patents will be issued or granted with respect to future patent applications, or that issued or granted patents will not later be found to be invalid or unenforceable, or that they will provide effective commercial protection to our products. The patent position of pharmaceutical companies is generally uncertain because it involves complex legal and factual considerations.

The standards applied by the USPTO, the European Patent Office or EPO, and foreign patent offices in granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in biopharmaceutical patents. Consequently, patents may not issue from future patent applications and the claim scope achieved may vary across territories.

The patent prosecution process is expensive and time-consuming, and we and our future licensors, licensees or collaboration partners may not be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we or our future licensors, licensees or collaboration partners will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Further, the issuance, scope, validity, enforceability and commercial value of our and our current or future licensors’, licensees’ or collaboration partners’ patent rights are highly uncertain. Our future patent applications may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. Moreover, in some circumstances, we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, covering technology that we license from or license to third parties and are reliant on our licensors, licensees or collaboration partners. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. If our current or future licensors, licensees or collaboration partners fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors, licensees or collaboration partners are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. The patent examination process may require us or our licensors, licensees or collaboration partners to narrow the scope of the claims of our or our licensors’, licensees’ or collaboration partners’ future patent applications, which may limit the scope of patent protection that may be obtained. We cannot assure you that all of the potentially relevant prior art relating to our patents and patent applications has been found. If such prior art exists, it can invalidate a patent or prevent a patent from issuing from a pending patent application.

Table of Contents

Even if patents do successfully issue, third parties may initiate an opposition, interference, re-examination, post-grant review, inter partes review, nullification or derivation action in court or before patent offices, or similar proceedings challenging the validity, enforceability or scope of such patents, which may result in the patent claims being narrowed or invalidated. For example, opposition proceedings at the EPO are increasingly common, and are costly and time consuming to defend. Furthermore, it is possible that we will need to defend other patents outside the EPO from challenges by others from time to time. It is possible that one or more of our US patents may be challenged by parties who file a request for post-grant review or inter partes review or ex parte reexamination.

Our patent rights may not be sufficient to provide us with a proprietary position in or competitive advantages in respect of our products or product candidates. We have been, and may in the future become, involved in post-grant proceedings in the US which are increasingly common and are costly to defend or prosecute. We may seek to modify or supplement relevant patent claims through reissuance proceedings, for example to submit prior art references not submitted during the prosecution of the US patent or to pursue additional claims within the scope of the originally issued claims but more tailored to our products or product candidates, in the course of which their patentability would be re-assessed, the legal scope of our patent protection may be limited or our application for a reissued patent may be refused. There can be no assurance that any or all of the originally issued claims will be reissued or that any or all of the additional claims that may be included in a petition will be granted in any such proceeding. In addition, we will be unable to enforce any such U.S. patent unless and until it is reissued. There can be no assurance that any such reissued US patent will not be challenged, invalidated or circumvented. Furthermore, even if the outcome of any reissuance proceeding is favorable to us, the enforcement of our intellectual property rights can be extremely expensive and time consuming.

Because patent applications are confidential for a period of time after filing, and some remain so until issued, we cannot be certain that we or our licensors were the first to file any patent application related to a product candidate. Furthermore, if third parties have filed such patent applications on or before March 15, 2013, an interference proceeding can be initiated by such third parties to determine who was the first to invent any of the subject matter covered by the patent claims of our applications. If third parties have filed such applications after March 15, 2013, a derivation proceeding can be initiated by such third parties to determine whether our invention was derived from theirs. Even where we have a valid and enforceable patent, we may not be able to exclude others from practicing our invention where the other party can show that they used the invention in commerce before our filing date or the other party benefits from a compulsory license.

Issued patents covering Nefecon, setanaxib or our present or future product candidates could be found invalid or unenforceable if challenged in court.

To protect our competitive position, we may from time to time need to resort to litigation in order to enforce or defend any patents or other intellectual property rights owned by or licensed to us, or to determine or challenge the scope or validity of patents or other intellectual property rights of third parties. Enforcement of intellectual property rights is difficult, unpredictable and expensive, and many of our or our licensors’ or collaboration partners’ adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we or our licensors or collaboration partners can. Accordingly, despite our or our licensors’ or collaboration partners’ efforts, we or our licensors or collaboration partners may not have sufficient resources or ability to prevent third parties from infringing upon or misappropriating intellectual property rights we own or control, particularly in countries where the laws may not protect those rights as fully as in the United States and Europe. We may fail in enforcing our rights, in which case our competitors may be permitted to use our technology without being required to pay us any license fees. In addition, litigation involving our patents carries the risk that one or more of our patents will be held invalid (in whole or in part, on a claim-by-claim basis) or held unenforceable. Such an adverse court ruling could allow third parties to commercialize our product candidates, and then compete directly with us, without payment to us.

If we were to initiate legal proceedings against a third party who we considered to be infringing a patent covering one of our products, the defendant could counterclaim that our patent is invalid or unenforceable. In patent litigation in the United States or in Europe, defendant counterclaims alleging invalidity or unenforceability are commonplace. A claim for a validity challenge may be based on failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. A claim for unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or the EPO or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on one or more of our product candidates. Such a loss of patent protection could have a material adverse impact on our business. Further, litigation could result in substantial costs and diversion of management resources, regardless of the outcome, and this could harm our business and financial results. Patents and other intellectual property rights also will not protect our technology if competitors design around our protected technology without infringing our patents or other intellectual property rights.

If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time consuming and could prevent or delay us from developing or commercializing our product candidates.

Our commercial success depends, in part, on our ability to develop, manufacture, market and sell Nefecon, setanaxib and our present or future product candidates without being sued for infringement of the intellectual property and other proprietary rights of third parties. However, our development and commercialization activities may be subject to claims that we infringe or otherwise violate patents or other intellectual property rights owned or controlled by third parties. Third parties may have US and non-US issued patents and pending patent applications relating to compounds, methods of manufacturing compounds and/or methods of use for the treatment of the disease indications for which we are developing our product candidates. If any third-party patents or patent applications are found to cover our product candidates or their methods of use or manufacture, we may not be free to manufacture or market our product candidates as planned without obtaining a license, which may not be available on commercially reasonable terms, or at all.

There is a substantial amount of intellectual property litigation in the biotechnology and pharmaceutical industries, and we may become party to, or threatened with, litigation or other adversarial proceedings regarding intellectual property rights with respect to our product and products candidates, including patent infringement lawsuits in Europe, United States or abroad, as well as interference, derivation, inter partes review, and post-grant proceedings before the USPTO and opposition or other proceedings before the EPO and other foreign patent offices. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the composition, use or manufacture of our products and product candidates. We cannot guarantee that any of our patent searches or analyses including, but not limited to, the identification of relevant patents, the scope of patent claims or the expiration of relevant patents are complete or thorough, nor can we be certain that we have identified each and every patent and pending application in the United States, Europe and other jurisdictions that is relevant to or necessary for the commercialization of our products and product candidates in any jurisdiction. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our products and product candidates may be accused of infringing. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Accordingly, third parties may assert infringement claims against us based on intellectual property rights that exist now or arise in the future. The outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance. The pharmaceutical and biotechnology industries have produced a significant number of patents, and it may not always be clear to industry participants, including us, which patents cover various types of products or methods of use or manufacture. The scope of protection afforded by a patent is subject to interpretation by the courts, and the interpretation is not always uniform. If we were sued for patent infringement, we would need to demonstrate that our product candidates, products or methods either do not infringe the patent claims of the relevant patent or that the patent claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents. Even if we are successful in these proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel could be diverted in pursuing these proceedings, which could significantly harm our business and operating results. In addition, parties making claims against us may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources, and we may not have sufficient resources to bring these actions to a successful conclusion.

If we are found to infringe a third party’s intellectual property rights, we could be forced, including by court order, to cease developing, manufacturing or commercializing the infringing product candidate or product. Alternatively, we may be required to obtain a license from such third party in order to use the infringing technology and continue developing, manufacturing or marketing the infringing product candidate or product. If we were required to obtain a license to continue to manufacture or market the affected product, we may be required to pay substantial royalties or grant cross-licenses to our patents. We cannot, however, be certain that any such license will be available on acceptable terms, if at all. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations as a result of claims of patent infringement or violation of other intellectual property rights. Further, the outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance, including the demeanor and credibility of witnesses and the identity of any adverse party. This is especially true in intellectual property cases that may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree. Furthermore, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us; alternatively, or additionally it could include terms that impede or destroy our ability to compete successfully in the commercial marketplace. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or administrative proceedings, there is a risk that some of our confidential information could be compromised by disclosure. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have material adverse effect on our ability to raise additional funds or otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property or claiming ownership of what we regard as our own intellectual property.

Our former, present and future employees may have had prior employment at universities or at other biotechnology or pharmaceutical companies. Some of these employees may have executed proprietary rights, non-disclosure, non-competition or other similar agreements, in connection with such previous employment. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed third-party intellectual property, including trade secrets or other proprietary information. Litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may sustain damages or lose key personnel, valuable intellectual property rights or the personnel’s work product, which could hamper or prevent commercialization of our technology, which could materially affect our commercial development efforts. Such intellectual property rights could be awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or products. Such a license may not be available on commercially reasonable terms or at all. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

In addition, while we typically require our employees, consultants and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own, which may result in claims by or against us related to the ownership of such intellectual property. If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our senior management and scientific personnel.

Table of Contents

We may become involved in lawsuits to protect or enforce our patent or other intellectual property, which could be expensive, time consuming and unsuccessful.

Competitors may infringe our patent, trademarks, copyrights or other intellectual property. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time consuming and divert the time and attention of our management and scientific personnel. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In any patent infringement proceeding, there is a risk that a court will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the court will construe the patent’s claims narrowly or decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our patent claims do not cover the invention. An adverse outcome in a litigation or proceeding involving our patent could limit our ability to assert those patents against those parties or other competitors and may curtail or preclude our ability to exclude third parties from making and selling similar or competitive products. Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party against whom we have asserted trademark infringement has superior rights to the trademarks in question. In this case, we could ultimately be forced to cease use of such trademarks.

Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could adversely affect the price of our common shares. Moreover, there can be no assurance that we will have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a result of the proceedings.

Additionally, for certain of our existing and future in-licensed patent rights, we may not have the right to bring suit for infringement and may have to rely on third parties to enforce these rights for us. If we cannot or choose not to take action against those we believe infringe our intellectual property rights, we may have difficulty competing in certain markets where such potential infringers conduct their business, and our commercialization efforts may suffer as a result.

Our ability to compete may be adversely affected if we are unsuccessful in defending against any claims by competitors or others that we are infringing upon their intellectual property rights.

The various markets in which we plan to operate are subject to frequent and extensive litigation regarding patents and other intellectual property rights. In addition, biopharmaceutical companies have employed intellectual property litigation as a means to gain an advantage over their competitors. As a result, we may be required to defend against claims of intellectual property infringement that may be asserted by our competitors against us and, if the outcome of any such litigation is adverse to us, it may affect our ability to compete effectively.

Our involvement in litigation, and in any interference, derivation, reexamination, inter partes review opposition or post-grant proceedings or other intellectual property proceedings inside and outside of the United States or Europe may divert management time from focusing on business operations, could cause us to spend significant amounts of money and may have no guarantee of success. Any current and potential intellectual property litigation also could force us to do one or more of the following:

stop selling, incorporating, manufacturing, or using our products in the US, Europe or other jurisdictions that use the subject intellectual property;
obtain from a third party asserting its intellectual property rights, a license to sell or use the relevant technology, which license may not be available on reasonable terms, or at all, or may be non-exclusive thereby giving our competitors access to the same technologies licensed to us;

45

Table of Contents

redesign those products or processes that use any allegedly infringing or misappropriated technology, which may result in significant cost or delay to us, or which redesign could be technically infeasible; or
pay damages, including the possibility of treble damages in a patent case if a court finds us to have willfully infringed certain intellectual property rights.

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, we could have a substantial adverse effect on our share price. Such litigation or proceedings could substantially increase our operating losses and reduce our resources available for development activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

We license intellectual property from third parties for Nefecon and may do so for certain of our present or future product candidates, and termination of any of these licenses could result in the loss of significant rights, which would substantially harm our business.

We have in-license rights with respect to a formulation patent for Nefecon and we may in-license additional intellectual property rights with respect to our present or future product candidates. Any termination of such licenses could result in the loss of significant rights and would cause material adverse harm to our ability to develop and commercialize any product or product candidate subject to such licenses.

Disputes may also arise between us and our licensors regarding intellectual property subject to a license agreement, including:

the scope of rights granted under the license agreement and other interpretation-related issues;
whether and the extent to which our technology and processes infringe intellectual property of the licensor that is not subject to the licensing agreement;
our right to sublicense patent and other rights to third parties under collaborative development relationships;
our diligence obligations with respect to the use of licensed technology in relation to our development and commercialization of our product candidates and what activities satisfy those diligence obligations; and
the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners.

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

We are generally also subject to all of the same risks with respect to protection of intellectual property that we own, as we are for intellectual property that we license, which are described below. If we or our licensors fail to adequately protect this intellectual property, our ability to commercialize products could materially suffer.

46

Table of Contents

We may not be successful in obtaining or maintaining necessary rights to our products or present or future product candidates through acquisitions and in-licenses.

Because our programs may require the use of proprietary rights held by third parties, the growth of our business will likely depend in part on our ability to acquire or in-license such proprietary rights. We may be unable to acquire or in-license any compositions, methods of use, processes, or other third-party intellectual property rights from third parties that we identify as necessary for our product candidates. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a number of more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size, cash resources and greater clinical development and commercialization capabilities.

In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment. If we are unable to successfully obtain a license to third-party intellectual property rights necessary for the development of a product candidate or program, we may have to abandon development of that product or product candidate or program and our business and financial condition could suffer.

If our trademarks and various brand elements are not adequately protected, then our business may be adversely affected in our markets of interest.

Our registered and unregistered trademarks, trade dress, get-up and trade names (collectively, brand elements) may be challenged, infringed, invalidated, declared generic or determined to be infringing on other registered or unregistered trademarks, unless adequate steps are taken to clear them before use, register them and then enforce them. It is vital that we are able to build brand recognition in these brand elements, to maximize the value to potential partners or customers in our markets of interest. Over the long term, if we are unable to establish brand recognition based on our various brand elements, then we may not be able to compete effectively, or indeed at all, and our business may be adversely affected.

If other entities use trademarks similar or identical to ours in different jurisdictions, or have senior rights to ours, we could be prevented from using our brand elements in certain jurisdictions, which may of course interfere with our use of our current trademarks throughout the world.

We enjoy only limited geographical protection with respect to certain patents and may face difficulties in certain jurisdictions, which may diminish the value of intellectual property rights in those jurisdictions.

We often file our first patent application (i.e., priority filing) with the USPTO, the EPO, or more typically, in the national office of a European country (e.g., in the UK or Sweden). International applications under the Patent Cooperation Treaty, or PCT, are filed within twelve months after the priority filing, with equivalent applications being filed simultaneously in territories not bound by the PCT, if any such territories are of sufficient commercial interest. From the PCT filing, we have the option to file national and regional patent applications in any of the 155 jurisdictions party to the PCT where we believe protection of our product candidates may be commercially valuable. We have filed for patent protection in territories that are of current commercial interest to us and have achieved grant in at least some of these territories. However, our commercial interests may extend beyond these territories meaning we may enter into markets in the future where we do not have patent protection or pending patent applications. In addition, we may decide to abandon national and regional patent applications before grant. Finally, the grant proceeding of each national/regional patent is an independent proceeding which may lead to situations in which applications might in some jurisdictions be refused by the relevant patent offices, while granted by others. It is also quite common that depending on the country, the scope of patent protection may vary for the same product or product candidate or technology.

Competitors may use our and our licensors’ or collaboration partners’ technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we and our licensors or collaboration partners have patent protection, but enforcement is not as strong as that in the United States and Europe. These products may compete with our products or product candidates, and our and our licensors’ or collaboration partners’ patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States and Europe, and companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we or our licensors encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished and we may face additional competition from others in those jurisdictions.

Some countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, some countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired and our business and results of operations may be adversely affected.

Proceedings to enforce our and our licensors’ or collaboration partners’ patent rights in foreign jurisdictions could result in substantial costs and divert our and our licensors’ or collaboration partners’ efforts and attention from other aspects of our business, could put our and our licensors’ or collaboration partners’ patents at risk of being invalidated or interpreted narrowly and our and our licensors’ or collaboration partners’ patent applications at risk of not issuing and could provoke third parties to assert claims against us or our licensors or collaboration partners. We or our licensors or collaboration partners may not prevail in any lawsuits that we or our licensors or collaboration partners initiate and the damages or other remedies awarded, if any, may not be commercially meaningful.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:

others may be able to make product candidates that are similar, but not identical, to our products or product candidates with workarounds such that the product is not covered by the claims of the patents that we own or have licensed;
the claims of our patents may not adequately cover our product, meaning others may be able to manufacture the same product and not infringe the claims of the patents that we own or have licensed;
the patents of third parties may have an adverse effect on our business;
we or our licensors or any current or future strategic partners might not have been the first to conceive or reduce to practice the inventions covered by the issued patent or pending patent application that we own or have exclusively licensed;
we or our licensors or any future strategic partners might not have been the first to file patent applications covering certain aspects of our inventions;
others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights;
it is possible that our pending patent applications will not lead to issued patents;
issued patents that we own or have exclusively licensed may not provide us with any competitive advantage, or may be held invalid or unenforceable, as a result of legal challenges by our competitors;
our competitors might conduct development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;
third parties performing manufacturing or testing for us using our products or technologies could use the intellectual property of others without obtaining a proper license; and
we may not develop additional technologies that are patentable.

Changes in patent laws or patent jurisprudence could diminish the value of patents in general, thereby impairing our ability to protect our products.

As is the case with other pharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the pharmaceutical industry involve both technological complexity and legal complexity. Therefore, obtaining and enforcing pharmaceutical patents is costly, time-consuming and inherently uncertain. In addition, the America Invents Act, or the AIA, has been enacted in the United States, resulting in significant changes to the US patent system.

An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” system for deciding which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention. A third party that files a patent application in the USPTO after that date but before us could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by the third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application, but circumstances could prevent us from promptly filing patent applications on our inventions.

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and providing opportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our US patents, even those issued before March 16, 2013. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in US federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. The AIA and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.

Additionally, the US Supreme Court and the Court of Appeals for the Federal Circuit have ruled on patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the US Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and protect other proprietary information.

We consider proprietary trade secrets, confidential know-how and unpatented know-how to be important to our business. We may rely on trade secrets or confidential know-how to protect our technology, especially where patent protection is believed to be of limited value. However, trade secrets and confidential know-how are difficult to maintain as confidential.

To protect this type of information against disclosure or appropriation by competitors, our policy is to require our employees, consultants, contractors, and advisors to enter into confidentiality agreements with us. However, current or former employees, consultants, contractors and advisers may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Enforcing a claim that a third party obtained illegally and is using trade secrets or confidential know-how is expensive, time consuming and unpredictable. The enforceability of confidentiality agreements may vary from jurisdiction to jurisdiction. Furthermore, if a competitor lawfully obtained or independently developed any of our trade secrets, we would have no right to prevent such competitor from using that technology or information to compete with us, which could harm our competitive position. Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating the trade secret.

Failure to obtain or maintain trade secrets or confidential know-how trade protection could adversely affect our competitive position. Moreover, our competitors may independently develop substantially equivalent proprietary information and may even apply for patent protection in respect of the same. If successful in obtaining such patent protection, our competitors could limit our use of our trade secrets or confidential know-how.

49

Table of Contents

Under certain circumstances, we may also decide to publish some know-how to attempt to prevent others from obtaining patent rights covering such know-how.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance and annuity fees on any issued patent are due to be paid to the USPTO, the EPO and national patent offices in several stages over the lifetime of the patent. The USPTO, the EPO and various foreign governmental patent offices require compliance with a number of procedural, documentaries, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our licensors or collaboration partners fail to maintain the patents and patent applications covering our product candidates, our competitors might be able to enter the market, which would have an adverse effect on our business.

Risks Related to Our Employee Matters, Managing Our Growth and Other Risks Relating to Our Operations

Our business and operations may be adversely affected by economic downturns, inflation, increases in interest rates, natural disasters, public health crises, political crises, geopolitical events or other macroeconomic conditions, which could negatively impact our business and financial performance.

The global economy, including credit and financial markets, has experienced extreme volatility and disruptions, including, among other things, severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, supply chain shortages, increases in inflation rates, higher interest rates and uncertainty about economic stability. The US Federal Reserve recently raised interest rates multiple times in response to concerns about inflation and it may raise them again. Higher interest rates, coupled with reduced government spending and volatility in financial markets may increase economic uncertainty and affect consumer spending. Any such volatility and disruptions may adversely affect our business or the third parties on whom we rely. If the equity and credit markets deteriorate, including as a result of political unrest or war, it may make any necessary debt or equity financing more costly or more dilutive or more difficult to obtain in a timely manner or on favorable terms, if at all. Increased inflation rates can adversely affect us by increasing our costs, including labor and employee benefit costs.

Our available cash and cash equivalents are held in accounts managed by third party financial institutions in the United States and in Europe and consist of cash in our operating accounts. At any point in time, the funds in our operating accounts at US financial institutions may exceed the Federal Deposit Insurance Corporation insurance limits. While we monitor the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail. We can provide no assurances that access to our operating cash or invested cash and cash equivalents will not be impacted by adverse conditions in the financial markets.

Terrorist attacks and international hostilities and instability in any region could adversely affect our business.

Terrorist attacks, the outbreak of war, or the existence of international hostilities could damage the world economy, adversely affect the global supply chain and adversely affect both our ability to sell our products to certain regions or purchase supplies from such regions. In particular, the warfare and political turmoil in Ukraine could adversely impact our financial condition, result of operations and cash flows. In February 2022, Russian troops invaded Ukraine. Although the severity and duration of the ongoing military action are highly unpredictable, the Russia-Ukraine military conflict could materially disrupt our operations in Europe and/or increase their costs. In addition, Russia’s prior annexation of Crimea, recent recognition of two separatist republics in the Donetsk and Luhansk regions of Ukraine and subsequent military interventions in Ukraine have led to sanctions being levied by the United States and other countries against Russia, Belarus and the two separatist republics in the Donetsk and Luhansk regions, with additional potential sanctions threatened and/or proposed. Russia’s military incursion and the resulting sanctions could adversely affect the global economy and financial markets and thus could affect our business, operations, operating results and financial condition as well as, potentially, the price of our common shares and ADSs.

50

Table of Contents

We also work with a global network of collaborators, suppliers, CROs and commercial partners, any of which may be directly or indirectly negatively impacted by the war in Ukraine and unrest in the region. Such negative impacts could indirectly affect our own business and operations. The extent and duration of the military action, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions caused by Russian military action or resulting sanctions may magnify the impact of other risks described in this annual report.

Our business depends on retaining our key personnel and recruiting additional qualified personnel.

Our success depends upon the continued contributions of our key management, scientific and technical personnel, who have been instrumental for us and have substantial experience with Nefecon and our other product candidates. The loss of key managers and senior scientists could delay our development activities, and we do not carry key person insurance. In addition, our ability to compete in the highly competitive biotechnology and pharmaceutical industries depends upon our ability to attract and retain highly qualified management, scientific and medical personnel. Many other biotechnology and pharmaceutical companies and academic institutions that we compete with for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. Therefore, we might not be able to attract new qualified personnel or retain our key persons on conditions that are economically acceptable. Furthermore, we will need to recruit new managers and qualified scientific personnel to develop our business if we expand into fields that will require additional skills. Our inability to attract qualified personnel and retain our key persons could prevent us from achieving our objectives and implementing our business strategy, which could have a material adverse effect on our business and prospects. Given the stage of our programs and our plans to expand operations, our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level and senior personnel across our organization.

We expect to continue to expand our development, regulatory and sales and marketing capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

We expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of drug development, manufacturing, regulatory affairs and sales and marketing. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

Our business is subject to economic, political, regulatory and other risks associated with international operations.

As a company incorporated and based in Sweden, our business is subject to risks associated with conducting business in Sweden, the US and internationally. Accordingly, our future results could be harmed by a variety of factors, including:

economic weakness, including inflation, or political instability in particular non-US economies and markets;
developments in the ongoing Russia-Ukraine military conflict;
differing regulatory requirements for product candidate approvals;
differing jurisdictions could present different issues for securing, maintaining or obtaining freedom to operate in such jurisdictions;
potentially reduced protection for intellectual property rights;
difficulties in compliance with different, complex and changing laws, regulations and court systems of multiple jurisdictions and compliance with a wide variety of foreign laws, treaties and regulations;
changes in non-US regulations and customs, tariffs and trade barriers;

differing reimbursement regimes and price controls in certain international markets;
negative consequences from changes in tax laws;
compliance with tax, employment, immigration and labor laws for employees living or traveling abroad, including, for example, the variable tax treatment in different jurisdictions of stock options granted under our employee stock plan or equity incentive plan;
workforce uncertainty in countries where labor unrest is more common than in the United States;
difficulties associated with staffing and managing international operations, including differing labor relations;
an outbreak of a contagious disease, such as coronavirus, which may cause us or our distributors, third party vendors and manufacturers and/or customers to temporarily suspend our or their respective operations in the affected city or country;
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires.

The UK’s withdrawal from the EU may have a negative effect on global economic conditions, financial markets and our business, which could reduce the price of our common shares.

The United Kingdom’s, or UK, withdrawal from the EU on January 31, 2020, commonly referred to as Brexit, has changed the regulatory relationship between the UK and the EU. The Medicines and Healthcare products Regulatory Agency, or MHRA, is now the UK’s standalone regulator for medicinal products and medical devices. Great Britain (England, Scotland and Wales) is now a third country to the EU. Northern Ireland will, with regard to EU regulations, continue to follow the EU regulatory rules for now.

Marketing authorizations in the UK are governed by the Human Medicines Regulations (SI 2012/1916), as amended. Since January 1, 2021, an applicant for the EU centralized procedure marketing authorization can no longer be established in the UK. As a result, since this date, companies established in the UK cannot use the EU centralized procedure and instead must follow one of the UK national authorization procedures or one of the remaining post-Brexit international cooperation procedures to obtain a marketing authorization to market products in the UK. All existing EU marketing authorizations for centrally authorized products were automatically converted or grandfathered into UK marketing authorization, effective in Great Britain only, free of charge on January 1, 2021, unless the marketing authorization holder opted-out of this possibility. Northern Ireland currently remains within the scope of EU authorizations in relation to centrally authorized medicinal products. Accordingly, until the Windsor Framework is implemented in Northern Ireland on January 1, 2025, products falling within the scope of the EU centralized procedure can only be authorized through UK national authorization procedures in Great Britain.

The MHRA has also introduced changes to national marketing authorization procedures. This includes introduction of procedures to prioritize access to new medicines that will benefit patients, including a 150-day assessment route, a rolling review procedure and the International Recognition Procedures which entered into application on January 1, 2024. Since January 1, 2024, the MHRA may also rely on the International Recognition Procedure, or IRP, when reviewing certain types of marketing authorization applications. This procedure is available for applicants for marketing authorization who have already received an authorization for the same product from a reference regulator. These include the FDA, the EMA, and national competent authorities of individual EEA countries. A positive opinion from the EMA and CHMP, or a positive end of procedure outcome from the mutual recognition or decentralized procedures are considered to be authorizations for the purposes of the IRP.

Table of Contents

There is no pre-marketing authorization orphan designation for medicinal products in the UK. Instead, the MHRA reviews applications for orphan designation in parallel to the corresponding marketing authorization application. The criteria are essentially the same as those in the EU, but have been tailored for the market. This includes the criterion that prevalence of the condition in Great Britain, rather than the EU, must not be more than five in 10,000. Upon the grant of a marketing authorization with orphan status, the medicinal product will benefit from up to 10 years of market exclusivity from similar products in the approved orphan indication. The start of this market exclusivity period will be set from the date of first approval of the product in Great Britain.

Since a significant proportion of the regulatory framework in the UK applicable to our business and our product candidates is derived from EU Directives and Regulations, Brexit could materially impact the regulatory regime with respect to the development, manufacture, importation, approval and commercialization of our product candidates in the UK or the EU, now that UK legislation has the potential to diverge from EU legislation. It is currently unclear to what extent the UK will seek to align its regulations with the EU in the future. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies governing clinical trials, our development plans may be impacted.

All of these changes could increase our costs and otherwise adversely affect our business. Any delay in obtaining, or an inability to obtain, any marketing approvals for our product candidates, as a result of Brexit or otherwise, would prevent us from commercializing our product candidates in the UK or the EU and restrict our ability to generate revenue and achieve and sustain profitability. In addition, we may be required to pay taxes or duties or be subjected to other hurdles in connection with the importation of our product candidates into the EU. If any of these outcomes occur, we may be forced to restrict or delay efforts to seek regulatory approval in the UK or the EU for our product candidates, or incur significant additional expenses to operate our business, which could significantly and materially harm or delay our ability to generate revenues or achieve profitability of our business. Any further changes in international trade, tariff and import/export regulations as a result of Brexit or otherwise may impose unexpected duty costs or other non-tariff barriers on us. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the UK.

Exchange rate fluctuations may materially affect our results of operations and financial condition.

Due to the international scope of our operations, our assets, earnings and cash flows are affected by fluctuations in the exchange rates of several currencies, particularly the Swedish Krona, the US dollar, the Swiss franc and the Euro. The functional currency of Calliditas Therapeutics AB and our consolidated subsidiaries is the Swedish Krona and a significant portion of our operating expenses are paid in US dollars, Swedish Krona and Swiss francs. The operating currency of our French and Swiss subsidiaries are the Euro and the Swiss franc, respectively.

Additionally, although we are based primarily in Sweden, we may receive payments from our business partners in US dollars and Euros, and we regularly acquire services, consumables and materials in US dollars and Euros. Further, potential future revenue may be derived from the United States, countries within the Euro zone and various other countries around the world. These future revenues may also be affected by fluctuations in foreign exchange rates which may, in turn, have a significant impact on our results of operations and cash flows from period to period. As a result, to the extent we continue our expansion on a global basis, we expect that increasing portions of our revenue, cost of revenue, assets and liabilities will be affected by fluctuations in currency valuations. We may, therefore, experience economic loss and a negative impact on earnings or net assets solely as a result of currency exchange rate fluctuations.

If our information technology systems, or those of third parties upon which we rely, or our data are or were compromised, we could experience adverse consequences resulting from such compromise, including but not limited to regulatory investigations or actions, litigation, fines and penalties, disruptions of our business operations, reputational harm, loss of revenue or profits, loss of customers or sales, and other adverse consequences.

In the ordinary course of our business, we, and the third parties upon which we rely, may collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (collectively, process) proprietary, confidential, and sensitive data, including personal data (such as health-related data), intellectual property, and trade secrets (collectively, sensitive information).

Cyberattacks, malicious internet-based activity, and online and offline fraud, and other similar activities threaten the confidentiality, integrity, and availability of our sensitive information and information technology systems, and those of the third parties upon which we rely. Such threats are prevalent and continue to rise, are increasingly difficult to detect and come from a variety of sources, including traditional computer “hackers,” threat actors, “hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated nation states, and nation-state-supported actors.

Some actors now engage and are expected to continue to engage in cyber-attacks, including without limitation nation-state actors for geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, we, the third parties upon which we rely, and our customers may be vulnerable to a heightened risk of these attacks, including retaliatory cyber-attacks, that could materially disrupt our systems and operations, supply chain, and ability to produce, sell and distribute our goods and services. For example, we have operations and third parties upon which we rely to support our business located in unstable regions and regions experiencing (or expected to experience) geopolitical or other conflicts.

We and the third parties upon which we rely may be subject to a variety of evolving threats, including but not limited to social-engineering attacks (including through deep fakes, which may be increasingly more difficult to identify as fake, and phishing attacks), malicious code (such as viruses and worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks, credential stuffing attacks, credential harvesting, personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or hardware failures, loss of data or other information technology assets, adware, and telecommunications failures, attacks enhanced or facilitated by AI, and other similar threats.

In particular, severe ransomware attacks, including by organized criminal threat actors, nation-states, and nation-state-supported actors, are becoming increasingly prevalent and can lead to significant interruptions in our operations, ability to provide our products or services, loss of sensitive data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments. Our partially remote workforce poses increased risks to our information technology systems and data, as more of our employees utilize network connections, computers and devices outside our premises or network, including working at home, while in transit and in public locations. Future or past business transactions (such as acquisitions or integrations) could expose us to additional cybersecurity risks and vulnerabilities, as our systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ systems and technologies. Furthermore, we may discover security issues that were not found during due diligence of such acquired or integrated entities, and it may be difficult to integrate companies into our information technology environment and security program.

We rely upon third-party service providers and technologies to operate critical business systems to process sensitive information in a variety of contexts, including, without limitation, cloud-based infrastructure, data center facilities, encryption and authentication technology, employee email, content delivery to customers, quality assurance, medical affairs and pharmaceutical promotion compliance tools and other functions. Our ability to monitor these third parties’ information security practices is limited, and these third parties may not have adequate information security measures in place. If our third-party service providers experience a security incident or other interruption, we could experience adverse consequences. While we may be entitled to damages if our third-party service providers fail to satisfy their privacy or security-related obligations to us, any award may be insufficient to cover our damages, or we may be unable to recover such award. In addition, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties’ infrastructure in our supply chain or our third-party partners’ supply chains have not been compromised. Similarly, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties and infrastructure in our supply chain or our third-party partners’ supply chains have not been compromised.

Any of the previously identified or similar threats could cause a security incident or other interruption that could result in unauthorized, unlawful, or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of, or access to our sensitive information. A security incident or other interruption could disrupt our ability (and that of the third parties upon whom we rely) to provide our products. interruptions in our operations, it could result in a material disruption of our development programs and our business operations. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third parties for the manufacture of our product candidates and to conduct clinical trials, and similar events relating to their information technology systems could also have a material adverse effect on our business. To the extent that any security incident or interruption were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development and commercialization of our future product candidates could be delayed.

Table of Contents

We may expend significant resources or modify our business activities (including our clinical trial activities) to try to protect against security incidents. Certain data privacy and security obligations may require us to implement and maintain specific security measures or industry-standard or reasonable security measures to protect our information technology systems and sensitive information. While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective. We may be unable in the future to detect vulnerabilities in our information technology systems because such threats and techniques change frequently, are often sophisticated in nature, and may not be detected until after a security incident has occurred. Despite our efforts to identify and address vulnerabilities, if any, in our information technology systems, our efforts may not be successful. Further, we may experience delays in developing and deploying remedial measures designed to address any such identified vulnerabilities.

Applicable data privacy and security obligations may require us to notify relevant stakeholders of security incidents, including affected individuals, customers, regulators, and investors, of security incidents. Such disclosures are costly, and the disclosure or the failure to comply with such requirements could lead to adverse consequences. If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security incident, we may experience adverse consequences, such as government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); additional reporting requirements and/or oversight; restrictions on processing sensitive information (including personal data); litigation (including class claims); indemnification obligations; negative publicity; reputational harm; monetary fund diversions; diversion of management attention; interruptions in our operations (including availability of data); financial loss; and other similar harms. Security incidents and attendant consequences may negatively impact our ability to grow and operate our business.

Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, damages, or claims related to our data privacy and security obligations. We cannot be sure that our insurance coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our privacy and security practices, that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.

We are subject to stringent and evolving US and foreign laws, regulations, rules, contractual obligations, industry standards, and other obligations related to data privacy and security. Our actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions, litigation (including class claims) and mass arbitration demands, fines and penalties, a disruption of our business operation, reputational harm, loss of revenue or profits, loss of customers or sales and other adverse business consequences.

In the ordinary course of our business, we process personal data and other sensitive information Our data processing activities subject us, and any potential collaborators, numerous data privacy and security obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and security policies, contracts, and other obligations that govern the processing of personal data by us and on our behalf.

In the United States, federal, state, and local governments have enacted numerous data privacy and security laws and regulations, including health information privacy laws, data breach notification laws, personal data privacy laws, and consumer protection laws, including Section 5 of the Federal Trade Commission Act could apply to our operations or the operations of our collaborators. For example, the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, imposes specific requirements relating to the privacy, security, and transmission of individually identifiable health information. We may obtain health information from third parties, including research institutions from which we obtain clinical trial data, that are subject to privacy and security requirements under HIPAA, as amended by HITECH. To the extent that we act as a business associate to a healthcare provider engaging in electronic transactions, we may also be subject to the privacy and security provisions of HIPAA, as amended by HITECH, which restricts the use and disclosure of protected health information, mandates the adoption of standards relating to the privacy and security of protected health information, and requires the reporting of certain security breaches to healthcare provider customers with respect to such information. Additionally, many states have enacted similar laws that may impose more stringent requirements on entities like ours. Depending on the facts and circumstances, we could be subject to significant civil, criminal, and administrative penalties if we violate HIPAA.

In the past few years, numerous U.S. states—including California, Virginia, Colorado, Connecticut, and Utah—have enacted comprehensive privacy laws that impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and affording residents with certain rights concerning their personal data. As applicable, such rights may include the right to access, correct, or delete certain personal data, and to opt-out of certain data processing activities, such as targeted advertising, profiling, and automated decision-making. The exercise of these rights may impact our business and ability to provide our products and services. Certain states also impose stricter requirements for processing certain personal data, including sensitive information, such as conducting data privacy impact assessments. These state laws allow for statutory fines for noncompliance. For example, the California Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020 or CPRA, (collectively, “CCPA”) applies to personal data of consumers, business representatives, and employees who are California residents, and requires businesses to provide specific disclosures in privacy notices and honor requests of such individuals to exercise certain privacy rights. The CCPA provides for fines of up to $7,500 per intentional violation and allows private litigants affected by certain data breaches to recover significant statutory damages. Although the CCPA exempts some data processed in the context of clinical trials, the CCPA increases compliance costs and potential liability with respect to other personal data we maintain about California residents. Similar laws are being considered in several other states, as well as at the federal and local levels, and we expect more states to pass similar laws in the future. While these states, like the CCPA, also exempt some data processed in the context of clinical trials, these developments further complicate compliance efforts, and increase legal risk and compliance costs for us, the third parties upon whom we rely, and our customers.

Outside the United States, an increasing number of laws, regulations, and industry standards govern data privacy and security. For example, the EU’s General Data Protection Regulation, or EU GDPR, and the United Kingdom’s GDPR, or UK GDPR, Brazil’s General Data Protection Law (Lei Geral de Proteção de Dados Pessoais, or LGPD) (Law No. 13,709/2018), and China’s Personal Information Protection Law or PIPL impose strict requirements for processing personal data. For example, under the GDPR, companies may face temporary or definitive bans on data processing and other corrective actions, fines of up to €20 million Euros under the EU GDPR, 17.5 million pounds sterling under the UK GDPR or, in each case, 4% of a company’s global annual revenues, whichever is greater, or private litigation related to processing of personal data brought by classes of data subjects, or consumer protection organizations authorized at law to represent their interests. There has been limited enforcement of the GDPR to date, particularly in pharmaceutical development, so we face uncertainty as to the exact interpretation of the new requirements on our trials and we may be unsuccessful in implementing all measures required by data protection authorities or courts in interpretation of the new law. The relationship between the UK and the EU in relation to certain aspects of data protection law remains unclear, and it is unclear how UK data protection laws and regulations will develop in the medium to longer term, and how data transfers to and from the UK will be regulated in the long term. These changes may lead to additional costs and increase our overall risk exposure.

In addition, we may be unable to transfer personal data from Europe and other jurisdictions to the United States or other countries due to data localization requirements or limitations on cross-border data flows. Europe and other jurisdiction have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries. In particular, the European Economic Area or EEA and the UK have significantly restricted the transfer of personal data to the United States and other countries whose privacy laws it generally believes are inadequate. Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross-border data transfer laws. Although there are currently various mechanisms that may be used to transfer personal data from the EEA and UK to the United States in compliance with law, such as the EEA standard contractual clauses, the UK’s International Data Transfer Agreement / Addendum, and the EU-U.S. Data Privacy Framework and the UK extension thereto (which allows for transfers to relevant U.S.-based organizations who self-certify compliance and participate in the Framework), these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States. Although there are currently various mechanisms that may be used to transfer personal data from the EEA and UK to the United States in compliance with law, such as the EEA standard contractual clauses, the UK’s International Data Transfer Agreement / Addendum, and the EU-U.S. Data Privacy Framework and the UK extension thereto (which allows for transfers to relevant U.S.-based organizations who self-certify compliance and participate in the Framework), these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States.

If there is no lawful manner for us to transfer personal data from the EEA, the UK or other jurisdictions to the United States, or if the requirements for a legally-compliant transfer are too onerous, we may face significant adverse consequences, including limiting our ability to conduct clinical trial activities in Europe and elsewhere, limiting our ability to collaborate with parties that are subject to such cross-border data transfer or localization laws, the interruption or degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions (such as Europe) at significant expense, increased exposure to regulatory actions, substantial penalties and fines, the inability to transfer data and work with partners, vendors, and other third parties, and injunctions against processing or transferring personal data necessary to operate our business. Additionally, companies that transfer personal data out of the EEA and UK to or other jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers out of Europe for allegedly violating the GDPR’s cross-border data transfer limitations.

Compliance with US and international data privacy and security obligations could require us to take on more onerous obligations in our contracts, restrict our ability to collect, use and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. Moreover, clinical trial subjects, employees and other individuals about whom we or our potential collaborators obtain personal data, as well as the providers who share this data with us, may limit our ability to collect, use and disclose the data. Claims that we have violated individuals’ privacy rights, failed to comply with data privacy and security laws, or breached our contractual obligations, even if we are not found liable, could be expensive and time-consuming to defend and could result in adverse publicity that could harm our business.

We are also bound by contractual obligations related to data privacy and security, and our efforts to comply with such obligations may not be successful. For example, certain privacy laws, such as the GDPR and the CCPA, require our customers to impose specific contractual restrictions on their service providers. We publish privacy policies, marketing materials and other statements, such as compliance with certain certifications or self-regulatory principles, regarding data privacy and security. If these policies, materials or statements are found to be deficient, lacking in transparency, deceptive, unfair, or misrepresentative of our practices, we may be subject to investigation, enforcement actions by regulators or other adverse consequences.

Obligations related to data privacy and security (and consumers’ data privacy expectations) are quickly changing, becoming increasingly stringent, and creating uncertainty. Additionally, these obligations may be subject to differing applications and interpretations, which may be inconsistent or conflict among jurisdictions. Preparing for and complying with these obligations requires significant resources and may necessitate changes to our information technologies, systems, and practices and to those of any third parties that process personal data on our behalf. We may at times fail (or be perceived to have failed) in our efforts to comply with our data privacy and security obligations. Moreover, despite our efforts, our personnel or third parties on whom we rely may fail to comply with such obligations, which could negatively impact our business operations.

If we or our third-party processors on which we rely fail, or are perceived to have failed. to address or to comply with applicable data privacy and security obligations, we could face significant consequences, including but are not limited to, government enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar); litigation (including class-action claims) and mass arbitration demands; additional reporting requirements and/or oversight; bans on processing personal data; and orders to destroy or not use personal data. In particular, plaintiffs have become increasingly more active in bringing privacy-related claims against companies, including class claims and mass arbitration demands. Some of these claims allow for the recovery of statutory damages on a per violation basis, and, if viable, carry the potential for monumental statutory damages, depending on the volume of data and the number of violations. Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers; interruptions or stoppages in our business operations (including, clinical trials); inability to process personal data or to operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or substantial changes to our business model or operations.

As a European public company with a registered office in Sweden, we will likely be subject to the sustainability disclosure requirements set out in the EU Corporate Sustainability Reporting Directive.

A growing number of investors, regulators, self-regulatory organizations and other stakeholders have expressed an interest in Environmental, Social and Corporate Governance (“ESG”) matters, and are requiring more robust ESG disclosures. The related legislative landscape in the EU has been evolving accordingly. For example, EU Directive No 2464/2022 on Corporate Sustainability Reporting (“CSRD”) was adopted and entered into force on January 5, 2023, amending the current EU Accounting Directive No 2013/34. The CSRD introduces new mandatory reporting obligations that will require the publication of audited sustainability information. The CSRD is supplemented by EU Delegated Regulation No 2023/2772 which establishes the first set of European Sustainability Reporting Standards (“ESRS”), which are applicable to in-scope EU entities. Further reporting standards are due to be adopted by June 2026, including for in-scope non-EU entities.

The CSRD and ESRS require certain mandatory disclosures, as well as disclosures of certain “material” sustainability matters in the company’s own operations, those of their subsidiaries and those of their value chain. The identification of material sustainability matters requires a “double materiality” assessment. This means that in-scope entities will have to assess both financial materiality (i.e., sustainability matters which generate risks or opportunities that affect, or could reasonably be expected to affect, the company’s financial position, financial performance, cash flows, access to finance or cost of capital over the short, medium or long term) and impact materiality (i.e., the company’s material actual or potential, positive or negative impacts on people or the environment over the short-, medium- and long-term.). Sustainability matters are material if they satisfy one or both of these materiality tests.

The CSRD applies to entities with securities admitted to trading on an EU regulated market, as well as large EU companies, EU parents of a “large group”, and to listed EU small or medium-sized enterprises, amongst others. It will also apply to non-EU companies that have a certain threshold of EU-generated turnover and an in-scope EU subsidiary or EU branch meeting the turnover thresholds. Companies subject to the CSRD are required to fulfil their reporting obligations in accordance with a staggered timeline depending on the category of company. The first reports are expected in 2025 for the 2024 financial year, predominantly for entities with securities admitted to trading on an EU regulated market, and in 2026 for the 2025 financial year for many other EU companies (including EU subsidiaries of non-EU parents) that are not listed on an EU regulated market but meet the relevant size thresholds.

In response to new ESG initiatives and regulations we may voluntarily elect, or be required, to adopt strategies, policies, or procedures related to ESG matters and report on these. Reporting on ESG goals and objectives may cause us to expend significant capital and human resources, and could divert management’s attention from central operational matters. Reports could also lead to the disclosure of information that which may have a negative impact on our operations and reputation which may lead to additional exposure. Failure to accurately comply with any ESG reporting obligations may result in enforcement actions, sanctions, reputational harm or private litigation.

The increasing use of social media platforms presents new risks and challenges.

Social media is increasingly being used to communicate about our clinical development programs and the diseases our therapeutics are being developed to treat, and we intend, in so far as is permitted by applicable laws, to utilize appropriate social media in connection with our commercialization efforts following approval of our product candidates, if any. Social media practices in the biotechnology and pharmaceutical industry continue to evolve and regulations and regulatory guidance relating to such use are evolving and not always clear. This evolution creates uncertainty and risk of noncompliance with regulations applicable to our business, resulting in potential regulatory actions against us, along with the potential for litigation related to off-label marketing or other prohibited activities and heightened scrutiny by the FDA, the SEC and other regulators, including equivalent foreign regulators. For example, patients may use social media channels to comment on their experience in an ongoing blinded clinical trial or to report an alleged adverse event. If such disclosures occur, there is a risk that trial enrollment may be adversely impacted, that we may fail to monitor and comply with applicable adverse event reporting obligations or that we may not be able to defend our business or the public’s legitimate interests in the face of the political and market pressures generated by social media due to restrictions on what we may say about our product candidates. There is also a risk of inappropriate disclosure of sensitive information or negative or inaccurate posts or comments about us on any social networking website. In addition, we may encounter attacks on social media regarding our company, management, product candidates or products. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur liability, face regulatory actions or incur other harm to our business.

Our business operations and current and future relationships with investigators, health care professionals, consultants, third-party payors and customers may be subject, directly or indirectly, to US federal and state, EU or foreign jurisdictions’ healthcare fraud and abuse laws, false claims laws, health information privacy and security laws, and other healthcare laws and regulations. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

Our current and future operations may be directly, or indirectly through our relationships with investigators, health care professionals, customers and third-party payors, subject to various US federal and state healthcare laws and regulations, including, without limitation, the US federal Anti-Kickback Statute. Healthcare providers, including physicians and others play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. These laws impact, among other things, our sales, marketing and education programs and constrain our business and financial arrangements and relationships with third-party payors, healthcare professionals and others who recommend, purchase, or provide our approved products, and other parties through which we research as well as market, sell and distribute our products for which we obtain marketing approval. In addition, we may be subject to patient data privacy and security regulation by both the US federal government and the states in which we conduct our business. Finally, our current and future operations are subject to additional healthcare-related statutory and regulatory requirements and enforcement by foreign regulatory authorities in jurisdictions in which we conduct our business. The laws that may affect our ability to operate include:

the US federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering, receiving or paying any remuneration (including any kickback, bribe, or certain rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, under US federal and state healthcare programs such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act, or FCA. The definition of the “remuneration” under the federal Anti-Kickback Statute has been interpreted to include anything of value. Further, courts have found that if “one purpose” of remuneration is to induce referrals, the federal Anti-Kickback Statute is violated. The Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers, and formulary managers on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution; but the exceptions and safe harbors are drawn narrowly and require strict compliance in order to offer protection. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances;

59

Table of Contents

federal civil and criminal false claims laws and civil monetary penalty laws, including the FCA, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, false or fraudulent claims for payment to, or approval by Medicare, Medicaid, or other federal healthcare programs, knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim or an obligation to pay or transmit money to the federal government, or knowingly concealing or knowingly and improperly avoiding or decreasing or concealing an obligation to pay money to the federal government. Manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to “cause” the submission of false or fraudulent claims. For example, manufacturers have been prosecuted for causing false claims to be submitted because of off-label promotion purportedly concealing price concessions in the pricing information submitted to the government for government price reporting purposes, and allegedly providing free product to customers with the expectation that the customers would bill federal healthcare programs for the product The FCA also permits a private individual acting as a “whistleblower” to bring actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery;
HIPAA, which created new federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity can be found guilty of violating HIPAA without actual knowledge of the statute or specific intent to violate it;
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their implementing regulations, and as amended again by the Final HIPAA Omnibus Rule, published in January 2013, which imposes certain obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information without appropriate authorization by covered entities subject to the rule, such as health plans, healthcare clearinghouses and certain healthcare providers, and business associates that perform certain services involving the use or disclosure of individually identifiable health information as well as their covered subcontractors. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions;
the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs;
the US federal legislation commonly referred to as Physician Payments Sunshine Act, and its implementing regulations, which requires certain manufacturers of drugs, devices, biologicals and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to report annually to the CMS information related to certain payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain other healthcare professionals (such as physicians assistants and nurse practitioners), and teaching hospitals, as well as ownership and investment interests held by physicians (as defined by such law) and their immediate family members;

Table of Contents

analogous state laws and regulations, including: state anti-kickback and false claims laws, which may apply to our business practices, including but not limited to, distribution, sales and marketing arrangements and claims involving healthcare items or services reimbursed by any third-party payor, including private insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the US federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral source, state laws and regulations that require drug manufacturers to file reports relating to pricing and marketing information, which requires tracking gifts and other remuneration and items of value provided to healthcare professionals and entities, state and local laws that require the registration of pharmaceutical sales representatives, and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts; and
the national laws of individual EU Member States and other foreign law equivalents of each of the laws, including reporting requirements detailing interactions with and payments to healthcare providers. Outside the United States, interactions between pharmaceutical companies and healthcare professionals are also governed by strict laws, such as national anti-bribery laws of European countries, national sunshine rules, regulations, industry self-regulation codes of conduct and physicians’ codes of professional conduct. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform. Federal and state enforcement bodies have continued their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry.

It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant sanctions, including civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating in government funded healthcare programs, such as Medicare and Medicaid or comparable foreign healthcare programs, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, reputational harm and the curtailment or restructuring of our operations. Prohibitions or restrictions on sales or withdrawal of marketed products could materially affect business in an adverse way. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, that person or entity may be subject to significant criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply with multiple jurisdictions with different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.

Our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.

We are exposed to the risk that our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violate the regulations of the FDA, the EC and comparable foreign regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities; healthcare fraud and abuse laws and regulations in the United States and abroad; or laws that require the reporting of financial information or data accurately. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials or creating fraudulent data in our preclinical studies or clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. We have adopted a code of conduct applicable to all of our employees, but it is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business, financial condition and results of operations.

We are subject to the UK Bribery Act 2010, the US Foreign Corrupt Practices Act of 1977, and other anti-corruption laws, as well as export control laws, import and customs laws, trade and economic sanctions laws and other laws governing our operations.

Our operations are subject to anti-corruption laws, including the UK Bribery Act 2010, or the Bribery Act, US Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, the US domestic bribery statute contained in 18 U.S.C. §201, the US Travel Act, the Swedish Penal Code, and other anti-corruption laws that apply in countries where we do business. The Bribery Act, FCPA and these other laws generally prohibit us and our employees and intermediaries from authorizing, promising, offering, or providing, directly or indirectly, a financial or other advantage, or anything of value, to government officials or other persons to induce them to improperly perform a relevant function or activity (or reward them for such behavior), or for any other improper purpose.

Under the Bribery Act, we may also be liable for failing to prevent a person associated with us from committing a bribery offense. We, along with those acting on our behalf and our commercial partners, operate in a number of jurisdictions that pose a high risk of potential Bribery Act or FCPA violations, and we participate in collaborations and relationships with third parties whose corrupt or illegal activities could potentially subject us to liability under the Bribery Act, FCPA or local anti-corruption laws, even if we do not explicitly authorize or have actual knowledge of such activities. In addition, we cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted.

Compliance with the Bribery Act, FCPA and these other anti-corruption laws is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, anti-corruption laws present particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital employees are considered government officials.

62

Table of Contents

We are also subject to other laws and regulations governing our international operations, including regulations administered by the governments of the UK, Sweden, Norway and the US, and authorities in the EU, including applicable export control regulations, economic sanctions and embargoes on certain countries and persons, anti-money laundering laws, import and customs requirements and currency exchange regulations, collectively referred to as the Trade Control laws. Exports and imports of our products must be made in compliance with these laws and regulations. Trade Control laws may also restrict or prohibit altogether the provision or supply of certain of our products to certain governments, persons, entities, countries, and territories, including those that are the target of comprehensive sanctions, unless there are license exceptions that apply or specific licenses are obtained. In addition, as a result of the Russia-Ukraine military conflict, the US, EU, UK, and other jurisdictions adopted a series of financial and trade sanctions in relation to Russia, Belarus, and certain Russian and Belarussian citizens and entities. Further sanctions against Russia and Belarus may be imposed by the UK, US and other jurisdictions as the Russia-Ukraine military conflict continues. Any changes in Trade Control laws, shift in the enforcement or scope of existing Trade Control laws, or change in the countries, governments, persons, or technologies targeted by such laws and regulations, could result in the decreased ability to export our products internationally.

There is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-corruption laws, including the Bribery Act, FCPA or other legal requirements, including Trade Control laws. If we are not in compliance with the Bribery Act, FCPA and other anti-corruption laws or Trade Control laws, we may be subject to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses. Such liabilities could have an adverse impact on our business, financial condition, results of operations and liquidity. Likewise, any investigation of any potential violations of the Bribery Act, FCPA, other anti-corruption laws or Trade Control laws could also have an adverse impact on our reputation, business, results of operations and financial condition. Further, the failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or debarment from government contracting.

We or the third parties upon whom we depend may be adversely affected by earthquakes or other natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Any unplanned event, such as flood, fire, explosion, earthquake, extreme weather condition, medical epidemics, power shortage, telecommunication failure or other natural or manmade accidents or incidents that result in us being unable to fully utilize our facilities, or the manufacturing facilities of our third-party contract manufacturers, may have a material and adverse effect on our ability to operate our business, particularly on a daily basis, and have significant negative consequences on our financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the development of our product candidates or interruption of our business operations. Earthquakes or other natural disasters could further disrupt our operations and have a material and adverse effect on our business, financial condition, results of operations and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters or our development operations, that damaged critical infrastructure, such as the manufacturing facilities of our third-party contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time. Disaster recovery and business continuity plans may prove inadequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business. As part of our risk management approach, we maintain insurance coverage at levels that we believe are appropriate for our business. However, in the event of an accident or incident at these facilities, we cannot assure you that the amounts of insurance will be sufficient to satisfy any damages and losses. If our facilities, or the manufacturing facilities of our third-party contract manufacturers, are unable to operate because of an accident or incident or for any other reason, even for a short period of time, any or all of our development programs may be harmed. Any business interruption may have a material and adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to the Ownership of our Securities

The price of our equity securities may be volatile and may fluctuate due to factors beyond our control.

The market price of the ADSs and our common shares has fluctuated significantly, and may continue to fluctuate significantly due to a variety of factors, including:

the commencement, enrollment or results of our planned and future clinical trials;
positive or negative results from, or delays in, testing and clinical trials by us, strategic partners or competitors;

63

Table of Contents

the amount of revenue from sales of TARPEYO in the United States, Kinpeygo in the EEA and UK, and Nefecon in other jurisdictions, if approved;
delays in entering into strategic relationships with respect to development or commercialization of our product candidates or entry into strategic relationships on terms that are not deemed to be favorable to us;
technological innovations or commercial product introductions by us or competitors;
changes or developments in laws or regulations applicable to our product candidates;
developments concerning proprietary rights, including patents and litigation matters;
public concern relating to the commercial value or safety of any of our product candidates;
the loss of any of our key scientific or management personnel;
announcements concerning our competitors or the biopharmaceutical industry in general;
actual or anticipated fluctuations in our operating results;
financing or other corporate transactions;
publication of research reports or comments by securities or industry analysts;
general market conditions in the biopharmaceutical industry or in the economy as a whole, including pandemics, bank failures, global armed conflicts, and related global economic uncertainty;
the trading volume or our ADSs on The Nasdaq Global Select Market or our common shares on Nasdaq Stockholm;
sales of our ADSs or common shares by us, members of our senior management and directors or our shareholders or the anticipation that such sales may occur in the future;
general economic, political, and market conditions and overall fluctuations in the financial markets in the United States or Sweden;
stock market price and volume fluctuations of comparable companies and, in particular, those that operate in the pharmaceutical industry;
investors’ general perception of us and our business; and
other events and factors, many of which are beyond our control.

The stock market in general, and The Nasdaq Global Select Market and pharmaceutical companies like ours in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Due to the potential volatility of our stock price, we may therefore be the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management’s attention and resources from our business.

64

Table of Contents

These and other market and industry factors may cause the market price and demand for our securities to fluctuate substantially, regardless of our actual operating performance, which may limit or prevent investors from readily selling their ADSs at or above the price paid for the ADSs and may otherwise negatively affect the liquidity of the ADSs. In addition, the stock market in general, and biopharmaceutical companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies.

We will continue to incur increased costs as a result of operating as a US-listed public company, and our board of directors will be required to devote substantial time to new compliance initiatives and corporate governance practices.

As a US-listed public company we will continue to incur significant legal, accounting and other expenses that we did not incur as a public company listed on Nasdaq Stockholm. The Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of The Nasdaq Stock Market, or Nasdaq, and other applicable securities rules and regulations impose various requirements on non-US reporting public companies, including the establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our board of directors and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, which in turn could make it more difficult for us to attract and retain qualified members of our board of directors.

However, these rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

Pursuant to Section 404 of the Sarbanes-Oxley Act, or Section 404, we are required to furnish a report on our internal control over financial reporting. In addition, we are required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404.

We have no present intention to pay dividends on our common shares in the foreseeable future and, consequently, your only opportunity to achieve a return on your investment during that time is if the price of the ADSs or common shares, as applicable, appreciates.

We have no present intention to pay dividends in the foreseeable future. Any recommendation by our board of directors to pay dividends will depend on many factors, including our financial condition (including losses carried-forward), results of operations, legal requirements, and other factors. Furthermore, pursuant to Swedish law, the calculation of amounts available for distribution to shareholders, as dividends or otherwise, must be determined on the basis of our non-consolidated statutory accounts prepared in accordance with Swedish accounting rules. If the price of the ADSs or the common shares declines before we pay dividends, you will incur a loss on your investment, without the likelihood that this loss will be offset in part or at all by potential future cash dividends.

We have identified material weaknesses in our internal control over financial reporting. If our remediation of these material weaknesses is not effective, or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations.

In connection with our preparation and the audits of our financial statements as of and for the years ended December 31, 2022 and 2023, we identified material weaknesses as defined under the Exchange Act and by the Public Company Accounting Oversight Board (United States) in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s financial statements will not be prevented or detected on a timely basis. All of these material weaknesses are described in detail in Item 15.B, “Management’s Annual Report on Internal Control over Financial Reporting.”

We initially identified some of these material weaknesses in our preparation and the audits of our financial statements as of and for the year ended December 31, 2022 and initiated a remediation plan, as further described in Item 15.B, to remediate the material weaknesses and to enhance our overall control environment. In fiscal 2023, we were able to complete remediation of the prior material weakness related to Entity-level control environment, IT Processes, and Payroll, and we continue to take action to remediate the remaining material weaknesses, including steps to increase dedicated resources, improve reporting processes and enhance related supporting technology. We will continue to enhance documentation of our risks-related controls and related assertions to facilitate tracking and analyzing internal control deficiency trends to support timely remediation. We will continue to leverage an outsourced team to perform independent testing of our internal controls throughout the year. We are committed to strengthen and further improve our internal control environment and implementing measures designed to help ensure that control deficiencies contributing to the material weakness are remediated as soon as possible, as further described below.

Although we intend to complete the remediation process as promptly as possible, we cannot at this time estimate how long it will take to remediate these material weaknesses, and our remediation plan may not prove to be successful. In addition, we may discover additional material weaknesses that require additional time and resources to remediate. Our failure to correct these material weaknesses or our failure to discover and address any other control deficiencies could result in inaccuracies in our financial statements and could also impair our ability to comply with applicable financial reporting requirements and make related regulatory filings on a timely basis. As a result, our business, financial condition, results of operations and prospects, as well as the trading price and listing of our ADSs may be materially and adversely affected. We cannot assure you that all of our existing material weaknesses have been identified, or that we will not identify additional material weaknesses in the future.

We are subject to reporting obligations under US securities laws and the Sarbanes-Oxley Act. Section 404 of the Sarbanes-Oxley Act requires that we include a report from management on the effectiveness of our internal control over financial reporting in this annual report. As a result of the material weaknesses identified above, our management has concluded that our internal control over financial reporting was not effective as of December 31, 2023. This conclusion could adversely impact the market price of our ADSs due to a loss of investor confidence in the reliability of our reporting processes.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, shareholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of the ADSs.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of the ADSs. For example, we have identified material weaknesses in our internal control over financial reporting related to our financial statement closing process. For example, we did not adequately design or execute controls that address the relevant financial statement assertions over the Financial Statement Close and Reporting Process. Specifically, we did not adequately design or execute internal controls over certain aspects of management review procedures, certain aspects of journal entry approvals and processing, general ledger master data maintenance, share-based payments and income taxes.

Pursuant to Section 404 of the Sarbanes-Oxley Act, we are required to perform system and process evaluation and testing of our internal control over financial reporting to allow our management to report on the effectiveness of our internal control over financial reporting and we are also required, as of this annual report, to have our independent registered public accounting firm issue an opinion on the effectiveness of our internal control over financial reporting on an annual basis. Based upon our evaluation, as of December 31, 2023, our Chief Executive Officer and Chief Financial Officer have concluded that the disclosure controls and procedures, in accordance with the Exchange Act Rule 13a-15(e), as a result of the material weaknesses in our internal control over financial reporting, as discussed in Item 15 of this report, were not effective. We may in the future discover additional weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Moreover, our internal controls over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. Moreover, we are aware that the remote working arrangements which is a function of specific roles potentially present new areas of risk, and we are carefully monitoring any impact to our internal controls and procedures.

If we continue to be unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our financial statements, the market price of our common shares could decline and we could be subject to sanctions or investigations by The Nasdaq Global Market, the SEC or other regulatory authorities.

Concentration of ownership of our common shares (including common shares in the form of ADSs) among our existing executive officers, directors and principal shareholders may prevent new investors from influencing significant corporate decisions.

Our executive officers, directors, greater than five percent shareholders and their affiliates beneficially own approximately 28.4% of our outstanding common shares (including common shares in the form of ADSs) as of February 29, 2024. Depending on the level of attendance at our general meetings of shareholders, these shareholders either alone or voting together as a group may be in a position to determine or significantly influence the outcome of decisions taken at any such general meeting. Any shareholder or group of shareholders controlling more than 50% of the share capital present and voting at our general meetings of shareholders may control any shareholder resolution requiring a simple majority, including the appointment of board members, certain decisions relating to our capital structure, and the approval of certain significant corporate transactions. Among other consequences, this concentration of ownership may prevent or discourage unsolicited acquisition proposals that you may believe are in your best interest as one of our shareholders. Some of these persons or entities may have interests different than yours. For example, to the extent certain shareholders purchased their shares or ADSs at prices below those at which other shareholders purchased theirs and have held their common shares for a longer period, they may be more interested in selling our company to an acquirer than other investors or they may want us to pursue strategies that deviate from the interests of other shareholders.

Currently, we are not aware that any of our existing shareholders have entered or will enter into a shareholders’ agreement with respect to the exercise of their voting rights. Nevertheless, depending on the level of attendance at our general meetings of shareholders, or the General Meeting, these significant shareholders could, alone or together, have the ability to determine the outcome of decisions taken at any such General Meeting. Any such voting by these shareholders may not be in accordance with our interests or those of our shareholders. Among other consequences, this concentration of ownership may have the effect of delaying or preventing a change in control and might therefore negatively affect the market price of the ADSs.

Fluctuations in exchange rates may increase the risk of holding ADSs and common shares.

Due to the international scope of our operations, our assets, earnings and cash flows are influenced by movements in exchange rates of several currencies, particularly the Swedish Krona, US dollar, Swiss franc and Euro. Our functional currency is the Swedish Krona, and some of our operating expenses are paid in Swedish Krona, but we also receive payments and pay expenses in US dollars and Euro. The operational currency of our French and Swiss subsidiaries is the Swiss franc. Further, potential future revenue may be derived from abroad, particularly from the United States. As a result, our business and the price of the ADSs and common shares on The Nasdaq Global Select Market and Nasdaq Stockholm, respectively, may be affected by fluctuations in foreign exchange rates between these currencies, which may also have a significant impact on our reported results of operations and cash flows from period to period.

Moreover, because our common shares currently trade on Nasdaq Stockholm in Swedish Krona, and the ADSs trade on The Nasdaq Global Select Market in US dollars, fluctuations in the exchange rate between the US dollar and the Swedish Krona may result in temporary differences between the value of the ADSs and the value of our common shares, which may result in heavy trading by investors seeking to exploit such differences.

Holders of ADSs are not treated as holders of our common shares.

Holders of ADSs are not treated as holders of our common shares unless they withdraw the common shares underlying their ADSs in accordance with the deposit agreement and applicable laws and regulations. The depositary is the holder of the common shares underlying the ADSs. Holders of ADSs therefore do not have any rights as holders of our common shares, other than the rights that they have pursuant to the deposit agreement. See “Item 12.D.—American Depositary Shares.”

Holders of ADSs may be subject to limitations on the transfer of their ADSs and the withdrawal of the underlying common shares.

ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary think it is advisable to do so because of any requirement of law, government or a governmental body, or under any provision of the deposit agreement, or for any other reason, subject to the right of ADS holders to cancel their ADSs and withdraw the underlying common shares. Temporary delays in the cancellation of your ADSs and withdrawal of the underlying common shares may arise because the depositary has closed its transfer books or we have closed our transfer books, the transfer of common shares is blocked to permit voting at a shareholders’ meeting or we are paying a dividend on our common shares. In addition, ADS holders may not be able to cancel their ADSs and withdraw the underlying common shares when they owe money for fees, taxes and similar charges and when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of common shares or other deposited securities. See “Item 12.D.—American Depositary Shares.”

Holders of ADSs will not have the same voting rights as the holders of our common shares and may not receive voting materials in time to be able to exercise your right to vote.

Except as described in this annual report and the deposit agreement, which was filed as an exhibit to the registration statement filed in connection with the initial public offering of our ADSs, holders of the ADSs will not be able to exercise voting rights attaching to the common shares represented by the ADSs. Under the terms of the deposit agreement, holders of the ADSs may instruct the depositary to vote the common shares underlying their ADSs. Otherwise, holders of ADSs will not be able to exercise their right to vote unless they withdraw the common shares underlying their ADSs to vote them in person or by proxy in accordance with applicable laws and regulations and our articles of association. Even so, ADS holders may not know about a meeting far enough in advance to withdraw those common shares. If we ask for the instructions of holders of the ADSs, the depositary, upon timely notice from us, will notify ADS holders of the upcoming vote and arrange to deliver our voting materials to them. Upon our request, the depositary will mail to holders a shareholder meeting notice that contains, among other things, a statement as to the manner in which voting instructions may be given. We cannot guarantee that ADS holders will receive the voting materials in time to ensure that they can instruct the depositary to vote the common shares underlying their ADSs. A shareholder is only entitled to participate in, and vote at, the meeting of shareholders, provided that it holds our common shares as of the record date set for such meeting and otherwise complies with our articles of association. In addition, the depositary’s liability to ADS holders for failing to execute voting instructions or for the manner of executing voting instructions is limited by the deposit agreement. As a result, holders of ADSs may not be able to exercise their right to give voting instructions or to vote in person or by proxy and they may not have any recourse against the depositary or us if their common shares are not voted as they have requested or if their shares cannot be voted.

Claims of US civil liabilities may not be enforceable against us.

We are incorporated under Swedish law. Certain members of our board of directors and senior management are non-residents of the US, and all or a substantial portion of our assets and the assets of such persons are located outside the US. As a result, it may not be possible to serve process on such persons or us in the US or to enforce judgments obtained in US courts against them or us based on civil liability provisions of the securities laws of the US. As a result, it may not be possible for investors to effect service of process within the US upon such persons or to enforce judgments obtained in US courts against them or us, including judgments predicated upon the civil liability provisions of the US federal securities laws.

The US and Sweden do not currently have a treaty providing for recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. Consequently, a final judgment for payment given by a court in the United States, whether or not predicated solely upon US securities laws, would not automatically be recognized or enforceable in Sweden. In addition, uncertainty exists as to whether the courts in Sweden would entertain original actions brought in Sweden against us or our directors or senior management predicated upon the securities laws of the US or any state in the US. Any final and conclusive monetary judgment for a definite sum obtained against us in US courts would not be automatically recognized. Instead, new proceedings would need to be initiated before the competent court in Sweden. However, a judgment obtained in the US may still have a strong evidentiary weight in the Swedish proceedings, depending on the circumstances and the assessment of the court. If a Swedish court gives judgment for the sum payable under a US judgment, the Swedish judgment will be enforceable by methods generally available for this purpose. As a result, US investors may not be able to enforce against us or certain of our directors any judgments obtained in US courts in civil and commercial matters, including judgments under the US federal securities laws.

We qualify as a foreign private issuer and, as a result, we are not subject to US proxy rules and are subject to reporting obligations under the Securities Exchange Act of 1934, as amended, that, to some extent, permit less detailed and frequent reporting than that of a US domestic public company.

We report under the Securities Exchange Act of 1934, as amended, or the Exchange Act, as a non-US company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to US domestic public companies, including (i) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act, (ii) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time and (iii) the rules under the Exchange Act requiring the filing with the Securities and Exchange Commission, or SEC, of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events. In addition, foreign private issuers are not required to file their annual report on Form 20-F until 120 days after the end of each fiscal year, while US domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers are also exempt from the Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information. As a result of the above, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers.

As a foreign private issuer and as permitted by the listing requirements of Nasdaq, we rely on certain home country governance practices rather than the corporate governance requirements of Nasdaq.

We are entitled to, and do, rely on a provision in Nasdaq’s corporate governance rules that allows us to follow Swedish law with regard to certain aspects of corporate governance. This allows us to follow certain corporate governance practices that differ in significant respects from the corporate governance requirements applicable to US companies listed on Nasdaq. For example, we are exempt from Nasdaq regulations that require a listed US company and follow home country practice with respect to (i) the minimum quorum requirement for a meeting of shareholders, (ii) the requirement that non-management directors to meet on a regular basis without management present and (iii) the composition of the nominating and corporate governance committee.

In accordance with our Nasdaq listing, our audit committee is required to comply with the provisions of Section 301 of the Sarbanes-Oxley Act, and Rule 10A-3 of the Exchange Act. Because we are a foreign private issuer, however, our audit committee is not subject to additional Nasdaq requirements applicable to listed US companies, including an affirmative determination that all members of the audit committee are “independent” using more stringent criteria than those applicable to us as a foreign private issuer. Furthermore, Nasdaq’s corporate governance rules require listed US companies to, among other things, seek shareholder approval for the implementation of certain equity compensation plans and issuances of common shares, which we are not required to follow, and do not intend to follow, as a foreign private issuer. Therefore, our shareholders may be afforded less protection than they otherwise would have under corporate governance listing standards applicable to US domestic issuers.

We may in the future lose our foreign private issuer status which would then require us to comply with the Exchange Act’s domestic reporting regime and cause us to incur significant legal, accounting and other expenses.

We are a foreign private issuer and therefore we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to US domestic issuers. In order to maintain our current status as a foreign private issuer, either (a) a majority of our common shares must be either directly or indirectly owned of record by non-residents of the US or (b) (i) a majority of our executive officers or directors may not be US citizens or residents, (ii) more than 50 percent of our assets cannot be located in the US and (iii) our business must be administered principally outside the US. We are required to evaluate our foreign private issuer status as of June 30 of each year. If we lose foreign private issuer status, we would be required to comply with the Exchange Act reporting and other requirements applicable to US domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC and Nasdaq rules. The regulatory and compliance costs to us under US securities laws if we are required to comply with the reporting requirements applicable to a US domestic issuer may be significantly higher than the cost we would incur as a foreign private issuer. As a result, we expect that a loss of foreign private issuer status would increase our legal and financial compliance costs and would make some activities highly time consuming and costly. We also expect that if we were required to comply with the rules and regulations applicable to US domestic issuers, it would make it more difficult and expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified members of our management team.

If securities or industry analysts cease coverage of us, or publish inaccurate or unfavorable research about our business, the price of the ADSs and our trading volume could decline.

The trading market for the ADSs will depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. Securities or industry analysts may elect not to provide research coverage of our ADSs, and such lack of research coverage may negatively impact the market price of our ADSs. If one or more of the analysts who cover us downgrade the ADSs or publish inaccurate or unfavorable research about our business, the price of the ADSs would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for the ADSs could decrease, which might cause the price of the ADSs and trading volume to decline.

Holders of ADSs may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could result in less favorable outcomes to the plaintiffs in any such action.

The deposit agreement governing the ADSs representing our common shares provides that, to the fullest extent permitted by applicable law, ADSs holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the US federal securities laws. The waiver to right to a jury trial of the deposit agreement is not intended to be deemed a waiver by any holder or beneficial owner of ADSs of our or the depositary’s compliance with the US federal securities laws and the rules and regulations promulgated thereunder.

If we or the depositary oppose a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable based on the facts and circumstances of that case in accordance with the applicable state and federal law. The enforceability of a contractual pre-dispute jury trial waiver in connection with claims arising under the federal securities laws has not been finally adjudicated by the US Supreme Court. However, we believe that a contractual pre-dispute jury trial waiver provision is generally enforceable, including under the laws of the State of New York, which govern the deposit agreement. In determining whether to enforce a contractual pre-dispute jury trial waiver provision, courts will generally consider whether a party knowingly, intelligently and voluntarily waived the right to a jury trial. We believe that this is the case with respect to the deposit agreement and the ADSs. It is advisable that you consult legal counsel regarding the jury waiver provision before investing in the ADSs.

If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary in connection with matters arising under the deposit agreement or the ADSs, including claims under federal securities laws, you or such other holder or beneficial owner may not be entitled to a jury trial with respect to such claims, which may have the effect of limiting and discouraging lawsuits against us and/or the depositary. If a lawsuit is brought against us and/or the depositary under the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may result in different outcome than a trial by jury would have had, including results that could be less favorable to the plaintiffs in any such action.

71

Table of Contents

Nevertheless, if this jury trial waiver is not permitted by applicable law, an action could proceed under the terms of the deposit agreement with a jury trial. No condition, stipulation or provision of the deposit agreement or our ADSs serves as a waiver by any holder or beneficial owner of ADSs or by us or the depositary of compliance with any provision of the US federal securities laws and the rules and regulations promulgated thereunder.

If we were to be classified as a “passive foreign investment company,” or a PFIC, there could be adverse US tax consequences to certain US holders.

Based on our analysis of our income, assets, activities and market capitalization for our taxable year ending December 31, 2023, we do not believe that we were a PFIC for our taxable year ending December 31, 2023. Because PFIC status is a fact specific determination that generally cannot be made until the close of the taxable year in question, the calculation of the value of our non-cash assets may be based in part on the value of our common shares or ADSs, the value of which may fluctuate considerably, and we hold a substantial amount of cash and cash equivalents, our PFIC status may change from year to year, it is difficult to predict whether we will be a PFIC for the current taxable year or any future year, and no assurance can be given that we will not be a PFIC for our current taxable year or any future year. Therefore, we have not yet made any determination as to our expected PFIC status for the current year. Even if we determine that we are not a PFIC after the close of a taxable year, there can be no assurance that the Internal Revenue Service, or IRS, will agree with our conclusion. Furthermore, because there are uncertainties in the application of the relevant rules, it is possible that the IRS may challenge our classification of certain income and assets as non-passive or our valuation of our tangible and intangible assets, each of which may result in us being treated as a PFIC. Our US counsel expresses no opinion with respect to our PFIC status for any prior, the current, or any future taxable year.

Under the Internal Revenue Code of 1986, as amended, we will be a PFIC for any taxable year in which (1) 75% or more of our gross income consists of passive income or (2) 50% or more of the average percentage of our gross assets (determined under applicable Treasury Regulations) consists of assets that produce, or are held for the production of, passive income. If we are a PFIC for any taxable year during which a US Holder (as defined below in “Item 10.E—Taxation—Certain United States Federal Income Tax Consequences”) holds our common shares, or ADSs, the US Holder may be subject to adverse tax consequences regardless of whether we continue to qualify as a PFIC, including ineligibility for any preferred tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred and additional reporting requirements. Each US Holder is strongly urged to consult its tax advisor regarding these issues. For further discussion of the adverse US federal income tax consequences in the event we are classified as a PFIC, see “Item 10.E—Taxation—Certain United States Federal Income Tax Consequences.”

If a United States person is treated as owning at least 10% of our common shares or ADSs, such holder may be subject to adverse US federal income tax consequences.

If a US Holder is treated as owning, directly, indirectly or constructively, at least 10% of the value or voting power of our common shares or ADSs, such US Holder may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our corporate group, if any. A controlled foreign corporation is any foreign corporation in which more than 50% of the total combined voting power of classes of voting stock or the total value of the corporation is owned (or treated as owned) by United States shareholders. Because our corporate group currently includes one or more US subsidiaries, our non-US subsidiaries will be treated as controlled foreign corporations, regardless of whether we are treated as a controlled foreign corporation. A United States shareholder of a controlled foreign corporation may be required to annually report and include in its US taxable income its pro rata share of “Subpart F income,” “global intangible low-taxed income” and investments in US property by controlled foreign corporations, regardless of whether we make any distributions. An individual that is a United States shareholder with respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United States shareholder that is a US corporation.

Failure to comply with these reporting obligations may subject a United States shareholder to significant monetary penalties and may prevent the statute of limitations with respect to such shareholder’s US federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist our investors in determining whether any of our non-US subsidiaries are treated as a controlled foreign corporation or whether such investor is treated as a United States shareholder with respect to any of such controlled foreign corporations. Further, we cannot provide any assurances that we will furnish to any United States shareholder information that may be necessary to comply with the reporting and tax paying obligations described in this risk factor. US Holders should consult their tax advisors regarding the potential application of these rules to their investment in our common shares or ADSs.

Future changes to tax laws could materially adversely affect our company and reduce net returns to our shareholders.

Our tax treatment is subject to changes in tax laws, regulations and treaties, or, in each case, the interpretation thereof, tax policy initiatives and reforms under consideration and the practices of tax authorities in jurisdictions in which we operate, as well as tax policy initiatives and reforms related to the Organization for Economic Co-Operation and Development’s (OECD), Base Erosion and Profit Shifting, Project (including “BEPS 2.0”), the EC’s state aid investigations and other initiatives. Such changes may include (but are not limited to) the taxation of operating income, investment income, dividends received or (in the specific context of withholding tax) dividends paid. In addition, on October 8, 2021, the OECD announced an agreement by members of the Inclusive Framework delineating an implementation plan, and on December 20, 2021, the OECD released model rules for the domestic implementation of a 15% global minimum tax. We are unable to predict what tax reform may be proposed or enacted in the future or what effect such changes would have on our business, but such changes, to the extent they are brought into tax legislation, regulations, policies or practices, could affect our financial position and overall or effective tax rates in the future in countries where we have operations, reduce post-tax returns to our shareholders, and increase the complexity, burden and cost of tax compliance.

Tax authorities may disagree with our positions and conclusions regarding certain tax positions, resulting in unanticipated costs, taxes or non-realization of expected benefits.

A tax authority may disagree with tax positions that we have taken, which could result in increased tax liabilities. For example, a tax authority could challenge our allocation of income by tax jurisdiction and the amounts paid between our affiliated companies pursuant to our intercompany arrangements and transfer pricing policies, including amounts paid with respect to our intellectual property development. Similarly, a tax authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a “permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions. A tax authority may take the position that material income tax liabilities, interest and penalties are payable by us, in which case, we expect that we might contest such assessment. Contesting such an assessment may be lengthy and costly and if we were unsuccessful in disputing the assessment, the implications could increase our anticipated effective tax rate, where applicable.

The rights of our shareholders may differ from the rights typically offered to shareholders of a US corporation.

Under Swedish corporate law, except in certain limited circumstances, which require at a minimum that a proposal for special review of accounts or a review of a specific item/topic as defined by shareholders requesting such review, has been supported by a minimum of 10% of the shareholders voting and being present at a general meeting, our shareholders may not ask for an inspection of our corporate records, while under Delaware corporate law any shareholder, irrespective of the size of such shareholder’s shareholdings, may do so. Shareholders of a Swedish limited company are also unable to initiate a derivative action, a remedy typically available to shareholders of US companies, in order to enforce a right of our company, in case we fail to enforce such right ourselves, other than in certain cases of board member/management liability under limited circumstances. In addition, a majority of our shareholders may release a member of our board of directors or our executive management from any claim of liability we may have, including if such board member or manager has acted in bad faith or has breached his or her duty of loyalty. However, a shareholder may bring a derivative action on behalf of our company against, among other persons, a member of our board of directors or our executive management, provided that the circumstances of the act or omission giving rise to the claim of liability were not known to the shareholders at the time of such shareholder resolution, or if shareholders representing at least 10% of the share capital represented at the relevant general meeting has opposed such shareholder resolution. In contrast, most US federal and state laws prohibit a company or its shareholders from releasing a board member from liability altogether if such board member has acted in bad faith or has breached such board member’s duty of loyalty to our company. Additionally, distribution of dividends from Swedish companies to foreign companies and individuals can be subject to non-refundable withholding tax, and not all receiving countries allow for deduction. See “Item 10.E.—Taxation—Material Swedish Tax Considerations” for a more detailed description of the withholding tax. Also, the rights as a creditor may not be as strong under Swedish insolvency law as under US law or other insolvency law, and consequently creditors may recover less in the event our company is subject to insolvency compared to a similar case including a US debtor. In addition, the use of the tax asset consisting of the accumulated tax losses requires that we are able to generate positive taxable income and the use of tax losses carried forward to offset against future income is subject to certain restrictions and can be restricted further by future amendments to Swedish tax law. Finally, Swedish corporate law may not provide appraisal rights in the case of a business combination equivalent to those generally afforded a shareholder of a US company under applicable US laws. As a result of these differences between Swedish corporate law and our articles of association, on the one hand, and US federal and state laws, on the other hand, in certain instances, you could receive less protection as an equity holder of our company than you would as a shareholder of a US company.

Holders of the ADSs will not be able to exercise the pre-emptive subscription rights related to the shares that they represent and may suffer dilution of their equity holding in the event of future issuances of our shares.

Under the Swedish Companies Act, our shareholders benefit from a pre-emptive subscription right on the issuance of shares for cash consideration only and not in the event of issuance of shares against non-cash contribution or debt conversion. Shareholders’ pre-emptive subscription rights, in the event of issuances of shares against cash payment, may be disapplied by a resolution of the shareholders at a general meeting of our shareholders and/or the shares may be issued on the basis of an authorization granted to the board of directors pursuant to which the board may disapply the shareholders’ pre-emptive subscription rights. The absence or waiver of pre-emptive rights for existing equity holders may cause dilution to such holders.

Furthermore, the ADS holders would not be entitled, even if such rights accrued to our shareholders in any given instance, to receive such pre-emptive subscription rights related to the shares that they represent. Rather, the depositary is required to endeavor to sell any such subscription rights that may accrue to the shares underlying the ADSs and to remit the net proceeds therefrom to the ADS holders pro rata. In addition, if the depositary is unable to sell rights, the depositary will allow the rights to lapse, in which case you will receive no value for these rights. Further, if we offer holders of our shares the option to receive dividends in either cash or shares, under the deposit agreement, ADS holders will not be permitted to elect to receive dividends in shares or cash, but will receive whichever option we provide as a default to shareholders who fail to make such an election.

We are a Swedish company with limited liability. The rights of our shareholders may be different from the rights of shareholders in companies governed by the laws of US jurisdictions.

We are a Swedish company with limited liability. Our corporate affairs are governed by our articles of association and by the laws governing companies incorporated in Sweden. The rights of shareholders and the responsibilities of members of our board of directors may be different from the rights and obligations of shareholders and boards of directors in companies governed by the laws of US jurisdictions. In the performance of its duties, our board is required by Swedish law to consider the interests of our company, its shareholders, its employees and other stakeholders, in all cases with due observation of the principles of reasonableness and fairness. It is possible that some of these parties will have interests that are different from, or in addition to, the interests of our shareholders.

Our articles of association designate specific courts in the US as the exclusive forum for certain US litigation that may be initiated by our shareholders, which could limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us.

Our articles of association provide that, unless we consent in writing to the selection of an alternative forum and without any infringement on Swedish forum provisions and without applying Chapter 7, Section 54 of the Swedish Companies Act (2005:551), the US District Court for the Southern District of New York shall be the sole and exclusive forum for resolving any complaint filed in the US asserting a cause of action arising under the Securities Act, or the Federal Forum Provision.

We recognize that the proposed Federal Forum Provision may impose additional litigation costs on shareholders in pursuing any such claims, particularly if the shareholders do not reside in or near the State of New York. Additionally, proposed Federal Forum Provision may limit our shareholders’ ability to bring a claim in a US judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage the filing of lawsuits against us and our directors, officers and employees, even though an action, if successful, might benefit our shareholders. In addition, while the Delaware Supreme Court ruled in March 2020 that federal forum selection provisions purporting to require claims under the Securities Act be brought in federal court are “facially valid” under Delaware law, there is uncertainty as to whether other US or Swedish courts will enforce our Federal Forum Provision. If the Federal Forum Provision is found to be unenforceable, we may incur additional costs associated with resolving such matters. The Federal Forum Provision may also impose additional litigation costs on shareholders who assert that the provision is not enforceable or invalid. The US District Court for the Southern District of New York may also reach different judgments or results than would other courts, including courts where a shareholder considering a US-based action may be located or would otherwise choose to bring the action, and such judgments may be more or less favorable to us than our shareholders.

The dual listing of our common shares and the ADSs may adversely affect the liquidity and value of the ADSs.

Our ADSs are listed on The Nasdaq Global Select Market and our common shares are listed on Nasdaq Stockholm. Trading of the ADSs or common shares, as applicable, in these markets will take place in different currencies (US dollars on Nasdaq and Swedish Kronor on Nasdaq Stockholm), and at different times (resulting from different time zones, different trading days and different public holidays in the US and Sweden). The trading prices of our common shares or ADSs, as applicable, on these two markets may differ due to these and other factors. Any decrease in the price of our common shares on Nasdaq Stockholm could cause a decrease in the trading price of the ADSs on Nasdaq. Investors could seek to sell or buy our common shares or ADSs to take advantage of any price differences between the markets through a practice referred to as arbitrage. Any arbitrage activity could create unexpected volatility in both the trading prices on one exchange and the common shares or Ads available for trading on the other exchange. In addition, holders of ADSs will not be immediately able to surrender their ADSs and withdraw the underlying common shares for trading on the other market without effecting necessary procedures with the depositary. This could result in time delays and additional cost for holders of ADSs. We cannot predict the effect of this dual listing on the value of our common shares and the ADSs. However, the dual listing of our common shares and the ADSs may reduce the liquidity of these securities in one or both markets and may adversely affect the development of an active trading market for the ADSs in the US.

We could be subject to securities class action litigation or other litigation matters.

From time to time we may become involved in certain litigation matters. In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because pharmaceutical companies have experienced significant securities price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

Although we intend to vigorously defend our interests in any litigation matters, there is no guarantee that we will be successful and we may have to pay damages awards or otherwise may enter into settlement arrangements in connection with such matters.

Any such negative outcome could result in payments of substantial damages or fines, damage to our reputation or adverse changes to our business practices. Furthermore, during the course of litigation, there could be negative public announcements of the results of hearings, motions or other interim proceedings or developments, which could have a negative effect on the market price of our ADSs. Even if we are successful in defending our interests in each matter, litigation with respect to such matters could result in substantial costs and significant adverse impact on our reputation and divert management’s attention and resources, which could have a material adverse effect on our business, operating results or financial condition

B.BUSINESS OVERVIEW

Overview

We are a commercial-stage specialty pharmaceutical company with the first product approved in the US and in EU for patients with the renal disease immunoglobulin A nephropathy, Nefecon, and a portfolio of innovative product candidates.

Nefecon is a proprietary, novel oral, delayed release formulation of budesonide designed to specifically target the presumed origin of the disease and provide a potentially disease modifying treatment of immunoglobin A nephropathy, or IgAN, for which there is a high unmet medical need. Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity that undergoes substantial first pass metabolism, resulting in limited systemic exposure. IgAN is a progressive, chronic disease that over time results in deterioration of kidney function in patients, many of whom are at risk of developing end-stage renal disease, or ESRD, with the need for dialysis or kidney transplant. Nefecon is designed to target the origin of the disease presumed to be located in the ileum, the distal region of the small intestine, which has the highest concentration of the Peyer’s patches, which are responsible for the production of pathogenic secretory immunoglobulin A, or IgA, antibodies.

The US Food and Drug Administration, or FDA, approved Nefecon under the brand name TARPEYO under accelerated approval on December 15, 2021 and we reported commercial availability in the United States in January 2022. Under accelerated approval, the indication for TARPEYO (budesonide) delayed release capsules (4mg) is reduction of proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a urine protein-to-creatinine ratio, or UPCR, ≥1.5gram/gram. In June 2023, we submitted a supplemental New Drug Application, or sNDA, to the FDA seeking to convert the accelerated approval to full approval for TARPEYO. On December 20, 2023, the FDA granted full approval to TARPEYO for a new indication to reduce the loss of kidney function in adults with IgAN who are at risk for disease progression. The European Commission, or EC, granted conditional marketing authorization for Nefecon under the name Kinpeygo (budesonide) capsules for the treatment of primary IgAN in adults at risk of rapid disease progression with a UPCR ≥1.5 gram/gram on July 15, 2022 and our licensee STADA Arzneimittel AG, or STADA, announced commercial availability in Germany in September 2022, and in Greece under a Special Import License since June 2023. On February 1, 2023, the Medicines and Healthcare products Regulatory Agency, or MHRA, of the UK granted Conditional Marketing Authorization for Kinpeygo for the same indication as the EC. STADA submitted requests to both the EMA, in September 2023, for the EU and to the MHRA, in October 2023, for the UK to convert the current conditional marketing authorization for these territories into a full marketing authorization. A decision is expected from the EMA during the first half of 2024. Nefecon received conditional approval from China’s National Medical Products Administration on November 24, 2023 for the reduction of proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a UPCR, ≥1.5gram/gram and approval from the Pharmaceutical Administration Bureau of the Macau Special Administrative Region on October 27, 2023 for the same indication. Nefecon received approval from Singapore’s Health Science Agency for the reduction of proteinuria in adults with IgAN at risk of rapid disease progression, generally a UPCR ≥1.5 g/g on March 19, 2024.

TARPEYO was the first treatment ever approved for the US market indicated for patients with IgAN. The FDA approved TARPEYO under the accelerated approval pathway based on the reduction in proteinuria and supportive data on the estimated Glomerular Filtration Rate, or eGFR, a measure of kidney function, shown in Part A of our pivotal NefIgArd trial. We reported topline results from the full NefIgArd clinical trial in March 2023. The trial met its primary endpoint with Nefecon demonstrating a highly statistically significant benefit over placebo (p value < 0.0001) in eGFR over the two-year period of nine months of treatment with Nefecon or placebo and 15 months of follow-up off drug. The results indicate that Nefecon was generally well-tolerated and the safety profile was consistent with that observed in Part A of the trial. These results were the basis for the June 2023 sNDA submission to the FDA to convert the accelerated approval to full approval for TARPEYO.

Nefecon as TARPEYO was granted seven years orphan drug exclusivity in the United States, expiry December 15, 2028, based on the initial indication based on proteinuria. Following the full approval in December of 2023, a new orphan drug exclusivity period of 7 years was granted for the new indication, expiring in December 2030. Kinpeygo, was granted ten years orphan market exclusivity by the EC, expiry July 15, 2032, and by the MHRA, expiring February 1, 2033.

We retain worldwide rights to Nefecon other than in territories where we have established strategic collaborations. In 2019, we entered into an agreement pursuant to which we granted Everest Medicines II Limited, or Everest, an exclusive license to develop and commercialize Nefecon for the treatment of IgAN in Greater China and Singapore, and in March 2022, we expanded the territory covered by the agreement to include the Republic of Korea. In July 2021, we entered into a license agreement with STADA to commercialize Nefecon for the treatment of IgAN in the EEA, the UK, and, if approved, in Switzerland. In December 2022, we entered into an exclusive license agreement with Viatris Pharmaceuticals Japan Inc., a subsidiary of Viatris Inc., or Viatris, to register and commercialize Nefecon for the treatment of IgAN in Japan.

We are also developing a novel platform of nicotinamide adenine dinucleotide phosphate, or NADPH, oxidase, or NOX, inhibitors, which we intend to primarily develop for orphan diseases with fibrotic pathology, with a main focus on kidney and liver diseases. From this platform, we are developing setanaxib, a NOX inhibitor, for the treatment of primary biliary cholangitis, or PBC. We are currently evaluating setanaxib in the TRANSFORM study, a Phase 2b clinical trial, in which we randomized the first patient in February 2022. Setanaxib will be administered to approximately 70-80 patients with PBC and elevated liver stiffness as well as intolerance or inadequate response to ursodeoxycholic acid, a generic drug also known as ursodiol or UDCA in a global trial conducted in 80-130 investigational centers in North America, Europe, Israel, Australia and New Zealand. The primary endpoint is alkaline phosphatase (ALP) reduction, with key secondary endpoints including change in liver stiffness and effect on fatigue and pruritus (itching). Following favorable safety data from a Phase 1 study, this trial will evaluate two dosing regimens of 1200mg/daily and 1600mg/daily. We expect data to read out data in the third quarter of 2024, and this analysis will determine which dose of setanaxib will be used for a future potential Phase 3 study. Setanaxib was granted fast track designation by the FDA in August 2021. We are also conducting a proof of concept, Phase 2 clinical trial of setanaxib administered in conjunction with pembrolizumab, a check point inhibitor, in squamous cell carcinoma of the head and neck, or SCCHN, in order to explore setanaxib’s use as a treatment approach in cancers with high levels of tumors associated fibroblasts, or CAFs. We are also currently conducting a Phase 2 clinical trial of setanaxib in Alport syndrome, which we initiated in November 2023.

Our Strategy

We aim to apply our interdisciplinary expertise in pharmaceutical product development to identify, develop and commercialize novel treatments in orphan indications, with an initial focus on renal and hepatic diseases with significant unmet medical needs. To achieve this objective, we intend to pursue the following strategies:

Support our partners in pursing regulatory approval for TARPEYO and Kinpeygo. We reported positive topline results from the full NefIgArd Phase 3 clinical trial in March 2023. Based on the topline results from the NefIgArd trial, our partner STADA has submitted requests to both the EMA, in September 2023, for the EU and to the MHRA, in October 2023, for the UK to convert the current conditional marketing authorization for these territories into a full marketing authorization. We expect a decision from EMA in the first half of 2024. Full approval for TARPEYO in the US was received in December of 2023. We are also supporting our partners Everest and Viatris in pursuing regulatory approvals of Nefecon in various jurisdictions in Asia.
Maximize the potential of Nefecon, where approved, through commercialization independently and through collaborations with third parties. Since the approval of TARPEYO in the United States in December 2021, we have been commercializing TARPEYO independently in the United States through a targeted commercial sales infrastructure. We launched TARPEYO in the United States in January 2022. Based on third party research we commissioned to assess the US nephrologist IgAN market, we believe this market can be served by a targeted and dedicated number of marketing and medical sales specialists to efficiently cover the approximately 4-5,000 nephrologists focused on our target patient population in the United States. In 2019, we granted a license to Everest to develop and commercialize Nefecon for IgAN and other potential indications in Greater China and Singapore. In March 2022, we expanded the territory covered by the agreement to include the Republic of Korea. In July 2021, we entered into a license agreement with STADA to commercialize Nefecon for the treatment of IgAN in the EEA, the UK and, if approved, in Switzerland. In December 2022, we entered into an exclusive license agreement with Viatris to register and commercialize Nefecon for the treatment of IgAN in Japan. We retain worldwide rights to Nefecon other than in Greater China, Singapore, the Republic of Korea, Europe and Japan and have entered into a Managed Access Program Distribution Agreement with TannerGAP, Inc. and Tanner Pharma UK Limited, or Tanner, under which Tanner agrees to act as the exclusive distributor for Calliditas to provide pre-approval access to the TARPEYO in response to requests by physicians, hospitals, pharmacies, distributors, ministries of health or other parties on behalf of specific or named patients, when the TARPEYO is not approved or licensed for use in the named patient’s home country.
Efficiently advance our first-in-class NOX platform candidate setanaxib through clinical trials. We believe that our leading product candidate, setanaxib, has potential to meaningfully impact fibrosis and inflammation, and hence provide significant benefit in orphan diseases, including in PBC. Setanaxib is the first clinical product candidate within the newly created “-naxib” international nonproprietary name stem designated by the World Health Organization. We are currently conducting a Phase 2/3 clinical trial in patients with PBC who have more advanced signs of liver fibrosis, as measured by Fibroscan. We are also conducting a proof of concept, Phase 2 clinical trial in SCCHN with setanaxib, administered in conjunction with pembrolizumab, a checkpoint inhibitor, in order to explore setanaxib’s use as a treatment approach in cancers with high levels of CAFs. In preclinical studies setanaxib has been shown to significantly reduce levels of CAFs in relevant mouse models of head and neck cancer, which in conjunction with administration of immunotherapies have resulted in tumor size reduction and overall survival benefits. Based on supportive pre-clinical data generated during 2022, we initiated a Phase 2a study with setanaxib in about 20 patients with Alport syndrome in November 2023.
Complement our existing pipeline by selective acquisitions or in-licensing of product candidates focused on nephrology, hepatic or orphan diseases. We actively seek to complement our existing pipeline by selectively acquiring or in-licensing additional product candidates that present a strong strategic and commercial fit. We believe that our team is well-positioned to identify attractive assets and accelerate their development. In particular, we seek to expand our pipeline with product candidates with an attractive risk/reward profile, such as those that have demonstrated proof-of-concept in patients, are in late-stage clinical development or can be rapidly advanced to market approval. We currently focus on, and we expect to continue to focus on, nephrology, hepatic and orphan diseases for our business development efforts.

Our Company and Management Team

We were formed in 2004 and we acquired Nefecon from Professors Bengt Fellström and Roger Hällgren at Uppsala University, Sweden. We are led by an experienced and dedicated management team with significant pharmaceutical industry experience, including at leading pharmaceutical companies such as GlaxoSmithKline, Novo Nordisk, Astra Zeneca, Pfizer and UCB. Our board of directors includes highly qualified researchers, pharmaceutical sector executives and experts in the fields of drug development, corporate development and pharmaceutical commercialization. We are supported by a highly regarded network of leading renal and hepatic experts, including prominent IgAN specialists throughout the world that serve as external advisors and investigators on clinical trials of Nefecon.

Our Commercial Product: TARPEYO for the treatment of IgAN

Overview

In November 2020, we reported positive topline data from Part A of our global, pivotal Phase 3 clinical trial, which we refer to as NefIgArd. In this trial of 200 patients, treatment with Nefecon was associated with a statistically significant and clinically meaningful reduction of protein in the urine, or proteinuria, and stabilization of kidney function. The primary endpoint analysis showed a 31% mean reduction in the treatment arm versus baseline, with placebo showing a 5% mean reduction versus baseline, resulting in a 27% mean reduction at nine months of the treatment arm versus placebo (p=0.0005). The key secondary endpoint, eGFR, showed a treatment benefit of 7% versus placebo at nine months, reflecting stabilization in the treatment arm and a 7% decline of eGFR in the placebo arm (p=0.0029). This reflected an absolute decline of 4.04 ml/min/1.73m2 in the placebo group over nine months compared to a 0.17 ml/min/1.73m2 decline in the treatment arm. Patients who had reached 12 months at the time of the data cut-off recorded a proteinuria reduction of 52% from baseline in the treatment arm, versus 7% in the placebo arm. In addition, the trial showed that Nefecon was generally well-tolerated.

We reported topline results from the Phase 3 NefIgArd clinical trial in March 2023. The trial met its primary endpoint with Nefecon demonstrating a highly statistically significant benefit over placebo (p value < 0.0001) in eGFR over the two-year period of nine months of treatment with Nefecon or placebo and 15 months of follow-up off drug. The eGFR benefit was observed across the entire study population, irrespective of UPCR baseline. UPCR reductions observed were durable, reflecting a long-lasting treatment effect during the 15 month follow-up period off treatment. The results indicate that Nefecon was generally well-tolerated and the safety profile was consistent with that observed in Part A of the trial. The NefIgArd trial was completed in June 2023 when the final 29 patients in China (not required for global submission purposes) completed nine months of treatment and 15 months of observation.

The FDA has approved TARPEYO (developed under the name of Nefecon) under the accelerated approval pathway based on the reduction in proteinuria. TARPEYO was the first ever approved treatment on the US market indicated for patients with IgAN. Based on the topline results from the Phase 3 NefIgArd clinical trial, in June 2023, we submitted an sNDA to the FDA seeking to convert the accelerated approval to full approval for TARPEYO. On December 20, 2023, the FDA granted full approval to TARPEYO for a new indication to reduce the loss of kidney function in adults with IgAN who are at risk for disease progression.

The EC has granted conditional marketing authorization for Nefecon under the name Kinpeygo (budesonide) capsules for the treatment of IgAN in adults at risk of rapid disease progression with a UPCR ≥1.5 gram/gram. On February 1, 2023, the MHRA granted conditional marketing authorization for Kinpeygo for the same indication as the EC. Our partner STADA has submitted requests to both the EMA, in September 2023, for the EU and to the MHRA, in October 2023, for the UK to convert the current conditional marketing authorization for these territories into a full marketing authorization.

TARPEYO was granted seven years orphan drug exclusivity in the United States, expiring December 15, 2028, for the accelerated approval indication, and was recently awarded orphan exclusivity through December 20, 2030 for that portion of the full approval indication not covered by the accelerated approval indication. Kinpeygo was granted ten years orphan market exclusivity by the EC, expiring in July 15, 2032, and by the MHRA, expiring February 1, 2033. Since the approval of TARPEYO in the United States in December 2021, we have been commercializing TARPEYO independently in the United States through a targeted commercial sales infrastructure. We launched TARPEYO in the United States in January 2022. In 2019, we granted a license to Everest to develop and commercialize Nefecon for IgAN and other potential indications in Greater China and Singapore. In March 2022, we expanded the territory covered by the agreement to include the Republic of Korea. In July 2021, we entered into a license agreement with STADA to commercialize Nefecon for the treatment of IgAN in the EEA, the UK and, if approved, in Switzerland. In December 2022, we entered into an exclusive license agreement with Viatris to register and commercialize Nefecon for the treatment of IgAN in Japan. We retain worldwide rights to Nefecon other than in Greater China, Singapore, the Republic of Korea, the EEA, Switzerland, the UK and Japan and have entered into a Managed Access Program Distribution Agreement with Tanner, under which Tanner agrees to act as the exclusive distributor for Calliditas to provide pre-approval access to the TARPEYO in response to requests by physicians, hospitals, pharmacies, distributors, ministries of health or other parties on behalf of specific or named patients, when the TARPEYO is not approved or licensed for use in the named patient’s home country.

IgAN Disease Background

IgAN, sometimes referred to as Berger’s disease, is a serious progressive disease of the kidney, in which up to 50% of patients are at risk of developing ESRD within ten to twenty years. The standard of care for ESRD is dialysis or kidney transplant, which represents a significant health economic burden as well as a material impact on patients’ quality of life. IgAN is an orphan disease that we estimate affects approximately 130,000 to 150,000 people in the United States and approximately 200,000 people in Europe. A significantly higher prevalence of IgAN has been observed in Asia, including in Greater China, where it has historically been a leading cause of ESRD. We estimate that IgAN affects approximately five million people in Greater China.

Although IgAN manifests in the kidney, there is now a consensus supporting a pivotal role of the mucosal immune system in the pathogenesis of the condition and that the origins of the disease reside in the mucosal tissue of the gastrointestinal tract. The intestine represents the largest component of the immune system in the body, and is a site of continuous exposure to antigens and pathogens. Masses of lymphatic tissue, known as Peyer’s patches, are concentrated in the ileum where they produce secretory IgA antibodies. IgA antibodies play a key role in the immune system by protecting the body from foreign substances such as food-derived factors, bacteria and viruses. Patients with IgAN have elevated levels of a subclass of IgA antibodies produced in the gut that lack units of galactose, a type of sugar, at their hinge region. The hinge region is a flexible amino acid stretch in the central part of the heavy chains of the IgA antibody. In IgAN patients, a combination of genetic predisposition, environmental, bacterial or dietary factors are presumed to lead to an increased production of these galactose-deficient IgA antibodies, potentially in combination with increased intestinal permeability, which leads to these antibodies appearing in the blood. The galactose-deficient IgA antibodies are immunogenic when found in the circulation, which triggers autoantibodies, or antibodies created by the body in response to a constituent of its own tissue. This in turn leads to the formation of pathogenic immune complexes, or clusters of antibodies, which deposit in the glomeruli, the kidney’s filtration apparatus. These trapped immune complexes initiate an inflammatory cascade that damages the glomeruli, resulting in protein and blood leaking into the urine. Ultimately the glomeruli are destroyed, reducing the kidney’s ability to remove waste products from the blood. As the disease progresses, waste products that are normally removed from the blood accumulate leading to potentially life-threatening complications that in many patients result in the need for dialysis or kidney transplant. Commercial patients on hemodialysis (in the US) average 145 sessions per year with costs that frequently exceed $250,000 per year. The average cost of a kidney transplant is approximately $415,000 with a total estimated annual cost in the US of $7.0 billion. The graphic below illustrates the pathogenesis of IgAN.

IgA production in the Peyer’s patches in the ileum is believed to cause IgAN in the kidney.

Treatment Landscape for IgAN Patients

Until the approval of TARPEYO and Kinpeygo (developed under the project name of Nefecon), there were no approved treatment options for IgAN. Physicians have attempted to control disease progression with a variety of off-label treatments. KDIGO (kidney disease improving global outcomes) Guidelines, a standard clinical assessment classification system used to predict risk for progression of kidney disease, were last updated in 2020, prior to the accelerated approval of TARPEYO. It recommends the use of blood pressure-lowering agents that inhibit or block the renin-angiotensin system, or RAS, using either inhibitors of angiotensin converting enzyme, or ACE inhibitors, or angiotensin receptor blockers, or ARBs. RAS inhibition reduces pressure in the kidney glomeruli, thereby lowering leakage and protein excretion in urine. Treatment via RAS inhibition is primarily symptomatic and does not address the underlying cause of IgAN. Over time, a significant proportion of patients experience continued deterioration of kidney function.

For IgAN patients whose disease has progressed, clinicians may treat patients with systemic immunosuppressive agents, primarily consisting of high doses of systemic corticosteroids, such as prednisone, prednisolone and methylprednisolone. While some published reports indicate that these agents may reduce proteinuria, the use of systemic corticosteroids is also associated with a wide range of adverse events, including high blood pressure, weight gain, diabetes, serious infections and osteoporosis.

The seriousness of these adverse events in patients with IgAN has been documented in two independent clinical trials investigating the safety and efficacy of systemic corticosteroids monotherapy and in combination with immunosuppressives. In the Therapeutic Evaluation of Steroids in IgA Nephropathy Global, or TESTING, clinical trial that was started in 2012 and conducted by The George Institute for Global Health based in Sydney, Australia, 262 patients who had progressive IgAN despite treatment with RAS blockade agents were randomized to receive oral corticosteroid methylprednisolone or placebo. A significantly higher rate of serious infections and two infection-related deaths were observed in patients receiving oral methylprednisolone, leading to temporary suspension of the trial in 2015 and a restart again in 2017 with a lower dose of methylprednisolone. Recently published results suggest this risk may be somewhat mitigated by reducing the dose of methylprednisolone and by administering prophylactic antibiotic treatment. In the open-label Supportive Versus Immunosuppressive Therapy for the Treatment of Progressive IgA Nephropathy, or STOP-IgAN, trial conducted by Rheinisch Westfälische Technische Hochschule of Aachen University in 162 patients, there was also an increase in the rate of serious infections including one infection related death in the 82 patients who received immunosuppressive therapy (systemic corticosteroids monotherapy or in combination with cyclophosphamide and azathioprine) in addition to supportive care. In this trial, immunosuppressives were not observed to have a lasting effect on proteinuria and there was no significant difference in the decline in eGFR. The STOP-IgAN trial concluded that the addition of immunosuppressive therapies, including systemic corticosteroids, to comprehensive supportive care was not beneficial in IgAN. We are expecting that the KDIGO Guidelines will be updated during 2024 and that these will include TARPEYO.

Our Solution: Nefecon

Nefecon is a proprietary, novel, oral formulation of budesonide, designed to deliver budesonide to the ileum of the small intestine, where the Peyer’s patches are concentrated. Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity that undergoes substantial first pass metabolism, resulting in limited systemic exposure. Nefecon was designed as a 4 mg delayed release capsule with an enteric coating so that it remains intact until it reaches the ileum. Each capsule contains beads coated with various polymers and budesonide designed to target the area with the highest concentration of Peyer’s patches, with the intention of having a disease-modifying effect.

Nefecon is designed to release budesonide in the ileum to provide peak drug concentrations to immune cells in the Peyer’s patches.

Graphic

As illustrated below, Nefecon has an enteric coating layer that delivers the capsule intact to the ileum of the small intestine, where the Peyer’s patches are concentrated. The capsule contains triple coated beads that help control the rate of release of the active ingredient, budesonide. Nefecon is thought to reduce the levels of circulating galactose deficient IgA and subsequently the production of IgA or IgG antibodies that bind to galactose deficient IgA to form immune complexes that accumulate in the kidneys causing renal injury.

Nefecon has two components: an enteric-coated layer that delivers the capsule intact to the ileum and triple coated beads that control the release of the active ingredient.

Graphic

Budesonide is an established corticosteroid that is generally well tolerated compared to other corticosteroids like prednisone. This active ingredient was selected because of its high first pass metabolism in the liver with minimal systemic absorption. Only a small portion of the orally administered active ingredient reaches the systemic circulation and therefore mitigates the risk of serious side effects that are typically associated with systemic corticosteroids that are used to treat IgAN.

Nefecon is differentiated in its indications, properties, profile and mechanism of action as compared to other marketed products that deliver budesonide to the intestine and is the only formulation of budesonide that is indicated for the treatment of IgAN. Uceris is formulated as a 9 mg extended release tablet administering budesonide specifically to the colon for the treatment of ulcerative colitis. Entocort is formulated as a 3 mg delayed release capsule used at a maximum dose of 9 mg throughout the entire approximately eight meters of the intestine in a continuous release for the treatment of Crohn’s disease. Unlike Nefecon, neither of these two formulations are designed to, or are in their approved dosages capable of, delivering the dose of budesonide to the ileum that was found to be efficacious for the treatment of IgAN in our clinical trials. Neither have been tested in randomized, controlled clinical trials in IgAN patients. We believe that any attempts to use these drugs to address IgAN would either be ineffective or would require dosing patients at levels several times higher than the doses approved, with unknown consequences for patient safety.

We have combined our proprietary formulation technology with know-how developed internally to create Nefecon. We believe this proprietary formulation will constitute a barrier to entry that would require significant time, focus and investment for a competitor to overcome. TARPEYO was initially granted seven years orphan drug exclusivity in the United States which was to expire on December 15, 2028, and was recently extended to December 2030 based on receiving full approval of TARPEYO. Kinpeygo was granted orphan drug market exclusivity in the EU and the UK, which will provide marketing exclusivity until July 15, 2032 and February 1, 2033, respectively.

Nefecon Phase 3 Clinical Trial (NefIgArd Trial)

We completed our global pivotal Phase 3 clinical trial in IgAN, which we refer to as NefIgArd. NefIgArd was a double-blind, placebo-controlled, two-part phase 3 clinical trial comparing nine months of Nefecon 16 mg once daily to placebo in IgAN patients on a stable recommended or maximum tolerated dose of RAS inhibitor therapy for control of blood pressure. We randomized our first patient in NefIgArd in November 2018, the results of the first part of the trial were published in a peer reviewed journal in October 2022, topline data from the full study were reported in March 2023, and full results from the trial were published in a peer reviewed journal in August 2023.

Trial Design

The first part of NefIgArd, which we refer to as Part A, was designed to evaluate reduction of the surrogate marker proteinuria, measured by the urine protein to creatinine ratio, or UPCR as its primary endpoint, which is the same endpoint used in our previously completed NEFIGAN clinical trial. In addition, a key secondary endpoint of Part A was the difference in kidney function between treated and placebo patients as measured by eGFR. This key secondary endpoint in Part A, measured over a nine-month period, provided information relevant to the primary endpoint of Part B.

The second part, which we refer to as Part B, was the post-approval confirmatory part of the trial designed to provide evidence of long-term renal benefit. Completion of enrollment of the additional 160 patients required for Part B took place in January 2021. The total number of 360 patients was required to sufficiently power the trial to assess the difference in kidney function between Nefecon-treated and placebo patients as measured by eGFR over a two-year period from the start of dosing of each patient. We reported positive topline results of Part B in March 2023. Across both parts of the study, NefIgArd enrolled a total of 366 patients in the global study.

NeflgArd Interim Results

We reported interim topline results in November 2020. The complete interim results from NeflgArd were published in a peer reviewed journal, Kidney International, in October 2022. The analysis set included 199 patients diagnosed with IgAN and who were on a background of optimized and stable renin-angiotensin system, or RAS inhibitor therapy. The patients were randomized in a 1:1 ratio into one of two arms-Nefecon 16 mg/day or placebo-and treated orally for nine months daily.

UPCR (Proteinuria) Data: Analysis of the primary UPCR endpoint showed that after nine months of treatment, patients treated with Nefecon showed a 31% reduction in UPCR compared to a 5% reduction in patients treated with placebo (p=0.0001). UPCR at nine months was reduced from baseline by 34% in patients treated with Nefecon compared with 5% in placebo-treated patients when applying an ITT (intention to treat) approach. The treatment effect for the UPCR endpoint at nine months was consistent across key subgroups, including key demographic (such as age, sex, race) and baseline disease (such as baseline proteinuria) characteristics. Based on the patients who had reached 12 months at the time of the data cut-off, proteinuria reduction was 52% from baseline compared to 7% for placebo treated patients.

eGFR Data: The key secondary endpoint, eGFR, showed a mean treatment benefit of 7% versus placebo at nine months, reflecting stabilization in the treatment arm and a 7% decline of eGFR in the placebo arm (p=0.0029). This corresponds to an absolute decline of 4.04 ml/min/1.73 m2 in the placebo arm over nine months compared to a 0.17 ml/min/1.73 m2 decline in the treatment arm.
Safety Profile: The results indicate that Nefecon was generally well-tolerated, with adverse events similar to those observed in the Phase 2b trial, and overall consistent with the known safety profile of Nefecon’s active ingredient, budesonide. The majority of adverse events were mild or moderate in severity. The withdrawal rate in this trial was less than 10%, hence significantly less than what was seen in the Phase 2b NEFIGAN trial.

NeflgArd Full Results

We reported topline results for the full study in March 2023. The analysis included 364 patients diagnosed with primary IgAN and who were on a background of optimized and stable renin-angiotensin system (RAS) inhibitor therapy. The patients were randomized in a 1:1 ratio into one of two treatment groups – Nefecon 16 mg/day orally or placebo – and treated for nine months daily, and then monitored for 15 months off-drug.

eGFR Data: The trial met its primary endpoint with Nefecon demonstrating a highly statistically significant benefit over placebo (p value < 0.0001) in eGFR over the two-year period of nine months of treatment with Nefecon or placebo and 15 months of follow-up off drug. On average, eGFR over 2 years was 5.05 mL/min/1.73 m2 higher with Nefecon compared to placebo (p<0.0001). Mean change in eGFR over the 2-year period was -2.47 mL/min/1.73 m2 for Nefecon 16 mg versus -7.52 mL/min/1.73 m2 for placebo. Supportive 2-year total slope analyses were statistically significant and clinically meaningful reflecting a sustained treatment benefit. The eGFR benefit was observed across the entire study population, irrespective of UPCR baseline.
UPCR (Proteinuria) Data: UPCR reductions observed were durable, reflecting a long-lasting treatment effect during the 15 month follow-up period off treatment.
Safety Profile: The results indicate that Nefecon was generally well-tolerated and the safety profile was consistent with that observed in Part A of the trial.

All patients enrolled into the NefIgArd trial have completed the 9-month treatment period and 15 months of observational follow-up. The last patient in China completed the study in June 2023 so the study has therefore concluded.

Open-Label Extension Trial

An open-label extension trial, or the OLE trial, for eligible patients who have completed treatment in Part A and Part B of NefIgArd is ongoing. The OLE trial commenced when the first patient completed both Part A and Part B of NefIgArd, which occurred in the fourth quarter of 2020, and we reported dosing of the first patient in February 2021. We expect the OLE trial to complete in first half of 2024.

Regulatory Approval and Plans

The FDA granted accelerated approval to TARPEYO on December 15, 2021 and we reported commercial availability of TARPEYO in the United States in January 2022. The FDA granted full approval to TARPEYO in December 2023 for a new indication to reduce the loss of kidney function in adults with IgAN who are at risk for disease progression.

The EC granted conditional marketing authorization for Kinpeygo on July 15, 2022 and our licensee STADA announced commercial availability in Germany in September 2022 and in Greece under a Special Import License since June 2023. On February 1, 2023, the MHRA granted conditional marketing authorization for Kinpeygo. Our partner STADA has submitted requests to both the EMA, in September 2023, for the EU and to the MHRA, in October 2023, for the UK to convert the current conditional marketing authorizations for these territories into a full marketing authorizations. We expect a decision from EMA in the first half of 2024.

TARPEYO was initially granted seven years orphan drug exclusivity in the United States which was to expire on December 15, 2028, and was recently extended to December 2030 based on receiving full approval of TARPEYO. Kinpeygo was granted ten years orphan market exclusivity by the EC, expiry July 15, 2032, and by the MHRA, expiring February 1, 2033.

Commercialization

We estimate the prevalence of IgA nephropathy in the United States to be between 130,000 and 150,000, with over 50% of patients potentially progressing to ESRD. Nephrologists, in syndicated research conducted and published in 2023 by Spherix Global Insights, anticipate 66% of their IgA nephropathy patients will progress to ESRD.

Following FDA approval, we began commercializing TARPEYO in the United States. Our targeted commercial sales infrastructure now consists of approximately 70 experienced rare disease account managers, focused on the approximate 4-5,000 nephrologists who we believe treat the vast majority of IgAN patients in the United States. TARPEYO sales began in late January 2022 and our US organization remains focused on disease and product education, so that physicians can identify appropriate patients for TARPEYO. In addition, we work with advocacy organizations and have developed a comprehensive patient services program to assist with access to TARPEYO.

In 2019, we granted a license to Everest to develop and commercialize Nefecon for IgAN and other potential indications in Greater China and Singapore. In March 2022, we expanded the territory covered by the agreement to include the Republic of Korea. In November 2022, we announced that Everest’s New Drug Application for Nefecon was accepted for review by the Chinese National Medical Products Administration. The Chinese National Medical Products Administration granted approval for Nefecon in November 2023 for the reduction of proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a UPCR ≥1.5gram/gram and approval from the Pharmaceutical Administration Bureau of the Macau Special Administrative Region on October 27, 2023 for the same indication. Nefecon was launched in Macau in December 2023. Approval was granted by Singapore’s Health Science Agency for Nefecon (for the reduction of proteinuria in adults with IgAN at risk of rapid disease progression, generally a UPCR ≥1.5 gram/gram to on March 19, 2024 for Nefecon.

In July 2021, we entered into a license agreement with STADA to commercialize Nefecon for the treatment of IgAN in the EEA, the UK and, if approved, in Switzerland. STADA is commercializing the product under the brand name Kinpeygo. STADA announced commercial availability of Kinpeygo in Germany in September 2022 and in certain other EU countries during 2023, including in Greece under a Special Import License since June 2023.

In December 2022, we entered into an exclusive license agreement with Viatris, to register and commercialize Nefecon for the treatment of IgAN in Japan.

We retain worldwide rights to Nefecon other than in Greater China, Singapore, the Republic of Korea, Europe, and Japan and have entered into a Managed Access Program Distribution Agreement with Tanner, under which Tanner agrees to act as the exclusive distributor for Calliditas to provide pre-approval access to the TARPEYO in response to requests by physicians, hospitals, pharmacies, distributors, ministries of health or other parties on behalf of specific or named patients, when the TARPEYO is not approved or licensed for use in the named patient’s home country.

Our pipeline: First-in-class NOX inhibitor platform with a lead product candidate: setanaxib

Introduction to NOX inhibitors

Nicotinamide adenine dinucleotide phosphate, or NADPH, oxidases, otherwise known as NOX enzymes, are the only known enzymes that are solely dedicated to producing reactive oxygen species, or ROS. They are transmembrane enzymes that transfer electrons from NADPH in the cytoplasm across the cell membrane, which results in the formation of ROS. There are seven NOX members, each differing in composition, modes of activation and the ROS type they produce. NOX1, NOX2, NOX3, and NOX5 transfer electrons from NADPH to molecular oxygen, producing superoxide anion (O2 −). NOX4, DUOX1 and DUOX2, meanwhile, mainly produce hydrogen peroxide (H2O2).

At appropriate concentrations, ROS have essential functions in cellular signaling processes, helping to regulate cell proliferation, differentiation and migration, as well as modulating the innate immune response, inflammation and fibrosis. However, disruption of redox homeostasis has been implicated in multiple disease pathways. Oxidative stress, caused by an excess of ROS, is a likely common underlying mechanism for many disorders, including cardiovascular diseases, neurodegenerative disorders, and cancer disease pathways. We believe our lead product candidate setanaxib impacts inflammation and fibrosis pathways, which also was seen in the transcriptomics analysis carried out in relation to the interim analysis of our Phase 2 SCCHN trial.

Setanaxib for the Treatment of PBC

Setanaxib has shown clinically relevant biochemical and anti-fibrotic activity in a Phase 2 clinical trial in PBC, an orphan liver disease in which fibrosis in an important part of the underlying pathology, despite not achieving its primary endpoint. Setanaxib is the first clinical product candidate within the newly created “-naxib” international nonproprietary name stem designated by the World Health Organization. Based on available Phase 2 clinical data and recent Phase 1 data, combined with interactions with the FDA related to setanaxib, we initiated a Phase 2b trial in this indication, with the first patient randomized in February 2022. We believe that setanaxib is differentiated from other approved or late-stage development candidates in PBC, due to its effect on fibrosis, inflammation, and potentially significant impact on fatigue, as seen in the Phase 2 trial. We have received orphan drug designation for the treatment of PBC by the FDA. Orphan designation was also granted in the EU prior to our acquisition of the product.

PBC Disease Background

PBC is a progressive and chronic autoimmune disease of the liver that causes a cycle of immune injury to biliary epithelial cells, resulting in cholestasis and fibrosis. The origin of the autoimmune response is believed to be the production of cytotoxic T-cells and B-cell derived autoantibodies directed towards the epithelial cells of the small bile ducts in the liver, resulting in inflammation and damage to the duct cells and eventually destroying the bile ducts. This destruction results in the accumulation of bile acids in the liver, a condition known as cholestasis, to levels that are toxic to the liver cells, resulting in destruction of liver cells and fibrosis. PBC can culminate in liver failure, necessitating the need for a liver transplant. PBC is an orphan disease and, based on its known prevalence rates, we estimate that there are approximately 140,000 patients in the United States. The annual incidence for PBC ranges from 0.3 to 5.8 cases per 100,000 in the United States.

Early symptoms include fatigue, itchy skin, dry eyes and mouth dryness. As the disease progresses, there is pain in the upper right abdomen, musculoskeletal pain, edema, jaundice, osteoporosis, elevated cholesterol and hypothyroidism. If untreated, the active liver tissue is destroyed and replaced by fibrous tissue, leading to cirrhosis liver failure and the need for a liver transplant. Individuals with PBC are also at a greater risk than the general population of developing hepatocellular carcinoma.

Current Treatments for PBC

Ursodeoxycholic acid, a generic drug also known as ursodiol, or UDCA, and obeticholic acid, marketed as Ocaliva by Intercept Pharmaceuticals, are the only FDA-approved treatments for PBC. Both of these agents are bile acid analogs whose mechanisms of action aim to protect the liver from damage caused by endogenous bile acids and inhibition of bile acid synthesis. These drugs are primarily anticholestatic. Neither of these drugs specifically addresses the autoimmune response that is believed to drive PBC or the inflammatory consequences of the autoimmune response. Approximately one-third of PBC patients do not respond adequately to UDCA and are at risk of requiring liver transplant. Despite showing improvements in liver enzymes in the blood, there is no clinical information currently available to show whether patients treated with OCALIVA live longer or if their symptoms improve. Although systemic corticosteroids have been shown to alleviate PBC symptoms, their adverse event profile limits their treatment potential.

Setanaxib Clinical Development

Based on earlier Phase 2 data and recent positive Phase 1 data, we initiated a Phase 2b trial in PBC. We believe that setanaxib is differentiated from other approved or late-stage development candidates in PBC, due to its effect on fibrosis, inflammation and potentially significant impact on fatigue, as seen in the Phase 2 trial. Setanaxib was developed initially by the Genkyotex group of companies, now our wholly-owned subsidiaries.

In a Phase 2 trial conducted by Genkyotex and concluded in 2019, setanaxib did not reach its selected primary endpoint of change in GGT (Gamma-glutamyl Transferase); however, it showed an effect on the secondary endpoint of ALP (Alkaline Phosphatase) and an effect on fibrosis as measured by a variety of biomarkers as well as Fibroscan. It also resulted in a statistically significant impact on fatigue, the most commonly reported symptom of PBC, and is the only drug candidate, to our knowledge, to achieve this to date in this patient population.

87

Table of Contents

In January 2021, Genkyotex reported positive data from its Phase 1 clinical trial to evaluate the safety and pharmacokinetics of setanaxib. The Phase 1 trial assessed the safety and pharmacokinetics of oral setanaxib at selected doses in 46 healthy adult male and female subjects. The trial consisted of a single ascending dose, or SAD, part and a multiple ascending dose, or MAD, part with dosing up to 1600 mg/day. The trial demonstrated that setanaxib was generally well tolerated at the doses tested, with no safety concerns or dose-limiting toxicity being identified.

In August 2021, we received FDA Fast Track Designation for setanaxib in PBC. Based on the positive data from the Phase 1 trial of setanaxib doses up to 1600 mg/day, we have initiated a 24-week, randomized, placebo-controlled, double-blind Phase 2b trial in PBC, incorporating higher doses than previously used in the Phase 2 trial and using the change in ALP as the primary endpoint. The first patient was randomized in this trial in February 2022. Setanaxib will be administered to approximately 70-80 patients with PBC and elevated liver stiffness as well as intolerance or inadequate response to UDCA in a global trial conducted in 80 to 130 investigational centers in North America, Europe, Israel, Australia and New Zealand. The primary endpoint is ALP reduction, with key secondary endpoints including change in liver stiffness and effect on fatigue and pruritus (itching). The trial will evaluate two dosing regimens of 800mg AM + 400mg PM, and 800mg twice daily.

Setanaxib – SCCHN

We are also evaluating setanaxib in head and neck cancer, building on promising in vivo preclinical data that suggests that setanaxib could function as an adjunct therapy to immune-oncology therapies. The response to immuno-oncology therapies can be affected by the tumor microenvironment, in particular by the numbers of tumor-infiltrating lymphocytes, or TILs, and cancer-associated fibroblasts, or CAFs, in the tumor. A relationship between CAFs and prognosis in squamous cell carcinoma of the head and neck, or SCCHN, has been established.

NOX4 is highly over-expressed in CAFs and drives myofibroblastic activation within tumors, shielding them from CD8+ TILs. Targeting CAFs with setanaxib could improve patients’ responses to immunotherapies, and function as an adjunct therapy. There is increasing use of pembrolizumab as first-line monotherapy in patients with relapsed or metastatic SCCHN, although response rates are low (ORR approx. 20%).

Using a CAF-rich tumor model in mice, administration of setanaxib + pembrolizumab (versus either treatment alone) resulted in improved penetration of TILs into the center of the tumor and slowing of tumor growth and improved survival.

We are conducting a Phase 2 proof-of-concept study in patients with head and neck cancer, which will investigate administration of setanaxib in conjunction with immunotherapy targeting CAFs. The graphic below depicts the trial design.

Graphic

The study will enroll approximately 50 patients. The first patient was randomized in the second quarter of 2022 and enrolment completed in the fourth quarter of 2023. The final analysis of the study is expected in the second quarter of 2024. An interim assessment of biomarker data (not subject to formal statistical analysis) conducted in mid-2023 provided evidence supporting that setanaxib may modulate gene expression associated with fibrosis pathways that have potential relevance for the tumor microenvironment.

Setanaxib – Other Indications

Alport syndrome is a genetic disease of collagen including mutations in COL4A3, COL4A4 and/or COL4A5. Prevalence is approximately 1 in 50,000 live births with a prevalence estimated to 30 – 60,000 persons in the US. It accounts for an estimated 3% of chronic kidney disease in children and 0.2% of adults with end-stage kidney disease in the United States. It is the second most common monogenic cause of chronic kidney disease after autosomal dominant polycystic kidney disease. Patients have a family history of kidney disease, urine abnormalities (haematuria, proteinuria) hearing impairment (sensorineural hearing loss), visual impairment (lens and retinal abnormalities). There are no approved treatments today, with RAS inhibitors used as supportive care.

Based on supportive pre-clinical data generated during 2022, we initiated a Phase 2a study with setanaxib in patients with Alport syndrome in November 2023; we plan to enroll 18 patients into the study. The study treatment period will be 24 weeks with the primary objective to investigate safety and tolerability, with secondary endpoints related to reduction of UPCR.

Setanaxib is also being evaluated in two Phase 2 investigator led trials. One is being conducted in type 1 diabetic kidney disease, or DKD. In addition, a grant from the United States National Institutes of Health, or NIH, of $8.9 million was awarded to the University of Alabama at Birmingham to fund a multi-year research program evaluating the role of NOX enzymes in idiopathic pulmonary fibrosis, or IPF, a chronic fibrosing lung disease. The core component of this program is a randomized, placebo-controlled Phase 2 trial with setanaxib in patients suffering from IPF, with topline data readout expected in the fourth quarter of 2024.

We believe this platform also has several other potential applications across orphan indications, focusing on anti-fibrotic and anti-inflammatory applications. Subject to positive data from ongoing trials, we could also see setanaxib as an important potential drug candidate for larger indications in oncology and NASH. Setanaxib is the lead compound, complemented by a research effort focused on developing follow up compounds.

Manufacturing

We rely on third parties to manufacture Nefecon. We have agreements with a third-party vendors to produce drug substance and drug product for Nefecon for our commercial needs and ongoing and planned clinical trials.

In December 2020, we entered into a Manufacturing Services Agreement (“MSA”) with Patheon Pharmaceutics Inc. (“Patheon”), a wholly-owned subsidiary of Thermo Fisher Scientific Inc., for certain manufacturing and quality control services. The MSA governs the general terms under which Patheon, or one of its affiliates, will provide non-exclusive manufacturing services for products specified by us from time to time. Each project under the MSA will be governed by a specific project agreement. Upon the entry of the MSA, the parties entered into a project agreement that provides for the manufacturing of Nefecon, pursuant to which Patheon will manufacture commercial supply of Nefecon from active pharmaceutical ingredient that we supply. The MSA and the Nefecon product agreement each have an initial term that expires on December 31, 2026, subject to renewal terms, as applicable. The MSA has customary termination and cancellation terms.

We require all of our contract manufacturing organizations, or CMOs, to conduct manufacturing activities in compliance with current good manufacturing practice, or cGMP, requirements. We currently rely solely on these CMOs for scale-up and process development work and to produce sufficient quantities of our commercial product and product candidates for use in clinical trials. We anticipate that these CMOs will have the capacity to support both clinical supply and commercial-scale production. We may also elect to enter into agreements with other CMOs to manufacture supplies of drug substance and finished drug product.

Competition

The pharmaceutical industry is characterized by rapid evolution of technologies and intense competition. While we believe that our products, product candidates, technology, knowledge, experience and scientific resources provide us with competitive advantages, we face competition from major pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and private research institutions, among others.

Smaller or earlier-stage companies, may also prove to be significant competitors, particularly through collaborative arrangements with large established companies. These companies may also compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites, enrolling patients in clinical trials and acquiring technologies complementary to, or necessary for, our programs.

A competitor may obtain FDA or other foreign regulatory approvals for their products more rapidly than we may obtain approvals for our product candidates, which could result in such competitor establishing a strong market position before we are able to commercialize our product candidates. In addition, the availability of reimbursement from government and private payors will also significantly impact the pricing and competitiveness of our products.

Nefecon, along with any other product candidates that we successfully develop and commercialize, competes with other approved treatment options, including off-label therapies, and new therapies that may become available in the future. Key considerations that impact our ability to effectively compete with other therapies include the efficacy, safety, method of administration, cost, level of promotional activity, regulatory market exclusivity and intellectual property protection of our products. Many of the companies against which we may compete have significantly greater financial resources and expertise than we do in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products.

On December 20, 2023 the FDA has approved TARPEYO (budesonide) delayed release capsules to reduce the loss of kidney function in adults with IgAN at risk for disease progression. TARPEYO was first approved in December 2021 under accelerated approval, based on the surrogate marker of proteinuria.

In February 2023, the FDA conditionally approved FILSPARI (sparsentan), an orally-administered small molecule indicated to reduce proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a UPCR ≥1.5 gram/gram. FILSPARI was developed and is commercialized by Travere Therapeutics, Inc. (previously Retrophin Inc.). This approval was granted based on positive proteinuria results from the Phase 3 trial with no supportive eGFR being presented. Due to risks of liver injury and birth defects, FILSPARI was approved with a boxed warning concerning hepatotoxicity and embryo-fetal toxicity and is only available through a restricted distribution program called the FILSPARI Risk Evaluation and Mitigation Strategies (REMS), requiring liver enzyme testing before initiation of treatment, monthly for the first year of treatment, and every three months thereafter and, for female patients, pregnancy testing before initiation of treatment and monthly thereafter. Prior to initiating treatment with FILSPARI, physicians are advised to discontinue use of renin-angiotensin-aldosterone system (RAAS) inhibitors, endothelin receptor antagonists (ERAs) or aliskiren. In September 2023, Travere Therapeutics announced that the Phase 3 Protect Study of FILSPARI missed its primary eGFR total slope endpoint vs. active control. In March 2024, Travere Therapeutics filed an sNDA seeking full approval of FILSPARI in the US.

In the fourth quarter of 2023, Novartis announced Phase 3 data from their IgAN studies with iptacopan (Factor B complement inhibitor) and atrasentan (endothelin receptor antagonist), and we anticipate that Novartis will file with the FDA for accelerated approval in 2024. Additionally, Novartis has also announced the commencement of a Phase 3 IgAN study with zigakibart (an anti-APRIL monoclonal antibody (mAb)). Both atrasentan and zigakibart were obtained by Novartis via the acquisition of Chinook Therapeutics in 2023.

We are aware of three additional Phase 3 IgAN programs that are ongoing and/or enrolling in the United States and Europe. Roche initiated their Phase 3 study with (licensed via Ionis Pharmaceuticals) IONIS-FB-LRx, Factor B complement inhibitor), Vera Therapeutics with atacicept (BAFF / APRIL inhibitor), Otsuka Corporation with sibeprenlimab (anti-APRIL mAb).

According to publicly available sources, several companies are developing product candidates for IgAN, including Alpine Immune Sciences Inc., BioCryst, Arrowhead Pharmaceuticals, Takeda, Alnylam Pharmaceuticals, AstraZeneca (with its subsidiary Alexion Pharmaceuticals), DiaMedica Therapeutics, MorphoSys, and Kira Pharma.

With respect to PBC, UDCA, a generic drug, and obeticholic acid, marketed as Ocaliva by Intercept Pharmaceuticals, Inc., are the only FDA-approved treatments for PBC. Additionally, we are aware that other companies are developing product candidates with pharmacologies distinct from setanaxib for this indication, the most advanced being peroxisome proliferator-activating receptor, or PPAR, agonists developed by Cymabay Therapeutics Inc, and Ipsen together with GENFIT SA which both have filed their INDs with the FDA during the fourth quarter of 2023 seeking approval for the treatment of PBC. Zydus Pharmaceuticals (USA) Inc. is also exploring a PPAR agonist in a Phase 2b/3 study. GlaxoSmithKline plc is conducting Phase 3 development of linerixibat, a sodium-bile acid cotransport inhibitor, for managing the pruritus symptoms of PBC. Additional compounds are in earlier phases of development.

Additionally, systemic corticosteroids, like prednisone, have been shown to alleviate symptoms associated with PBC but are associated with increased rates of osteoporosis.

There are currently no approved therapies for the treatment of AIH in the United States and there are few product candidates in development for this indication. We are aware of an injectable immunosuppressive monoclonal antibody in Phase 2/3 clinical development by Novartis AG and Kezar Life Sciences has initiated a Phase 2 study with zetomipzomib. The standard of care for the treatment of AIH includes immunosuppressive systemic corticosteroids, typically prednisone, alone or in combination with azathioprine.

Intellectual Property

We strive to protect the proprietary technologies that we believe are important to our business, including pursuing and maintaining patent protection intended to cover the technologies incorporated into, or used to produce, our product candidates, including compositions of matter of our product candidates and their methods of use, as well as other inventions that are important to our business. In addition to patent protection, we also rely on trade secrets to protect aspects of our business that we do not consider appropriate for patent protection, including certain aspects of our technology and drug product manufacturing. Our commercial success depends in part upon our ability to obtain and maintain patent and other proprietary protection for commercially important technologies, inventions and know-how related to our business, defend and enforce our intellectual property rights, particularly our patent rights, preserve the confidentiality of our trade secrets and operate without infringing valid and enforceable intellectual property rights of others.

Patents

The patent positions for biotechnology companies like us are generally uncertain and can involve complex legal, scientific and factual issues. In addition, the coverage claimed in a patent application can be significantly reduced before a patent is issued, and its scope can be reinterpreted and even challenged after issuance. As a result, we cannot guarantee that any of our technologies and product candidates will be protectable or remain protected by enforceable patents. We cannot predict whether the inventions and patent applications we are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient proprietary protection from competitors. Any patents that we hold may be challenged, circumvented or invalidated by third parties.

With regard to Nefecon, we co-own one patent family with Kyowa Kirin Services Ltd., f/k/a Archimedes Development Ltd., to which we have a sole and exclusive global license, even in relation to the other co-owner, in any field of use. This patent family protects a formulation for the oral delivery of budesonide and the medicinal use thereof. The patents in this patent family expire in 2029 provided all renewal fees are paid within the prescribed period, which we intend to do. The patents in this family include a United States patent, a patent in each of China, Hong Kong and Japan and a European patent that has been validated in 15 countries (Austria, Belgium, Switzerland, Germany, Denmark, Spain, Finland, France, the UK, Italy, the Netherlands, Norway, Poland, Sweden and Turkey). The patents in this family are not eligible for extension in the United States because the active ingredient is used in existing approved drugs. In Europe, extension of the patents is not likely subject to the recent judgement of litigation in the EU, CJEU C-443/17, related to the degree to which it is possible to obtain a Supplementary Protection Certificate for a previously authorized active ingredient. In January 2024, the USPTO issued a new patent to us relating to the method of treating IgA nephropathy which expires in 2043.

With regard to the NOX estate, there are four patent families covering various aspects of the setanaxib asset derived from four PCT applications. The composition of matter and certain methods of therapy are covered in two of these patent families. The third covers the use of setanaxib in certain oncology indications, including head and neck cancer. The fourth covers the use of setanaxib in the prevention and/or treatment of an osteoclastogenesis dysfunction related with increased bone turnover or bone resorption of secondary cause and/or osteoporosis. There is one additional patent family that covers other NOX inhibitors and their use. As our NOX inhibitor patents and applications cover new chemical entities, the territorial coverage is generally quite wide, and as the compounds do not yet form part of an approved drug product, patent life may potentially be extended in countries where legislation provides for patent term extension. The two families covering setanaxib’s composition of matter have projected expiry dates in 2028 and 2029, excluding potential extensions.

Trade Secrets

In addition to patents, we rely on trade secrets and know-how to develop and maintain our competitive position. For example, we believe we have gained significant know-how related to the composition, manufacturing process and the drug release performance of Nefecon through our extensive product development work. We typically rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for patent protection. We protect trade secrets and know-how by establishing confidentiality agreements and invention assignment agreements with our employees, consultants, scientific advisors, contractors and partners. These agreements generally provide that all confidential information developed or made known during the course of an individual or entity’s relationship with us must be kept confidential during and after the relationship. These agreements also generally provide that all inventions resulting from work performed for us or relating to our business and conceived or completed during the period of employment or assignment, as applicable, shall be our exclusive property. In addition, we take other appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary information by third parties.

Government Regulation

Our product candidates must be approved by the FDA through the NDA process before they may be legally marketed in the United States and by the EC following a positive opinion provided by the EMA through the marketing authorization application process for a drug falling within the scope of the centralized procedure or by a national Competent Authority through other marketing authorization application processes (national procedure, mutual recognition or decentralized procedure) before they may be legally marketed in the EU. Medicines with orphan designation fall within the mandatory scope of the centralized procedure. Our product candidates will be subject to similar requirements in other countries prior to marketing in those countries. The process of obtaining regulatory approvals and the compliance with applicable federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources.

United States Government Regulation

In the United States, the FDA regulates drugs under the FDCA and its implementing regulations. Drugs are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and compliance with appropriate federal, state, local and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable US requirements at any time during the drug development process, approval process or after approval may subject an applicant and/or sponsor to a variety of administrative or judicial sanctions, including imposition of a clinical hold, refusal by the FDA to approve applications, withdrawal of an approval, import/export delays, issuance of warning letters and other types of enforcement letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA and the Department of Justice or other governmental entities.

The clinical testing, manufacturing, labeling, storage, distribution, record keeping, advertising, promotion, import, export and marketing, among other things, of our product candidates are governed by extensive regulation by governmental authorities in the United States and other countries. The steps required by the FDA before a drug may be approved for marketing in the United States generally include:

completion of extensive preclinical, laboratory tests, animal studies and formulation studies in accordance with applicable regulations, including the FDA’s Good Laboratory Practice, or GLP, regulations;
the submission to the FDA of an IND application for human clinical testing, which must become effective before human clinical trials commence;
approval by an IRB representing each clinical site before each clinical trial may be initiated;
performance of adequate and well-controlled human clinical trials, in accordance with applicable IND and GCP requirements, to establish the safety and efficacy of the drug for each proposed indication;
preparation and submission to the FDA of an NDA;
FDA acceptance, review and approval of the NDA, which might include an advisory committee review;
satisfactory completion of an FDA inspection of the manufacturing facilities at which the drug, or components thereof, are made to assess compliance with current good manufacturing practices, or cGMPs; and
satisfactory completion of FDA audits of clinical trial sites to assure compliance with GCPs and the integrity of the clinical data; and agreement for compliance with any post-approval requirements, including Risk Evaluation and Mitigation Strategies, or REMS, and any post-approval studies required by the FDA.

The testing and approval process requires substantial time, effort and financial resources, and the receipt and timing of any approval is uncertain. The FDA may suspend clinical trials at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk.

Preclinical and Human Clinical Trials in Support of an NDA

Preclinical studies include laboratory evaluations of the product candidate, as well as in vitro and animal studies to assess the potential safety and efficacy of the product candidate. The conduct of preclinical studies is subject to federal regulations and requirements including GLP regulations. The results of the preclinical studies, together with manufacturing information and analytical data, among other things, are submitted to the FDA as part of the IND, which must become effective before human clinical trials may commence. The IND will become effective automatically 30 days after receipt by the FDA, unless the FDA raises concerns or questions about the conduct of the trials as outlined in the IND prior to that time and places a clinical hold on the IND. In this case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can proceed. The FDA may nevertheless initiate a clinical hold after the 30 days if, for example, significant public health risks arise.

Table of Contents

Clinical trials involve the administration of the product candidate to human subjects under the supervision of qualified investigators in accordance with GCP requirements, which include the requirement that all research subjects provide their informed consent in writing for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, subject selection and exclusion criteria, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. Each clinical trial must be reviewed and approved by an IRB at or servicing each of the sites at which the trial will be conducted. The IRB will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution. The IRB also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completion.

Clinical trials are typically conducted in three sequential phases prior to approval, but the phases may overlap or be combined. These phases generally include the following:

Phase 1. Phase 1 clinical trials represent the initial introduction of a product candidate into human subjects, frequently healthy volunteers. In Phase 1, the product candidate is usually tested for safety, including adverse effects, dosage tolerance, absorption, distribution, metabolism, excretion and pharmacodynamics.

Phase 2. Phase 2 clinical trials usually involve studies in a limited patient population to (1) evaluate the efficacy of the product candidate for specific indications, (2) determine dosage tolerance and optimal dosage and (3) identify possible adverse effects and safety risks.

Phase 3. If a product candidate is found to be potentially effective and to have an acceptable safety profile in Phase 2 clinical trials, the clinical trial program will be expanded to Phase 3 clinical trials to further demonstrate clinical efficacy, optimal dosage and safety within an expanded patient population at geographically dispersed clinical trial sites.

In some cases, the FDA may approve an NDA for a product candidate but require the sponsor to conduct additional clinical trials to further assess the product candidate’s safety and effectiveness after approval. Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after approval to gain additional experience from the treatment of patients in the intended therapeutic indication and to document a clinical benefit in the case of drugs approved under accelerated approval regulations, or when otherwise requested by the FDA in the form of post-market requirements or commitments. Failure to promptly conduct any required Phase 4 clinical trials could result in enforcement action or withdrawal of approval. Companies that conduct certain clinical trials also are required to register them and post the results of completed clinical trials on a government-sponsored database, such as ClinicalTrials.gov in the United States, within certain timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

Progress reports detailing the results of clinical trials, among other information, must be submitted at least annually to the FDA. Within 15 calendar days after the sponsor determines that the information qualifies for reporting, written IND safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events, findings from other studies or animal or in vitro testing that suggest a significant risk to humans exposed to the drug and any clinically important increase in the rate of a serious adverse reaction over that listed in the protocol or investigator brochure. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within 7 calendar days after the sponsor’s initial receipt of the information.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things, must have in place methods for testing the identity, strength, quality and purity of the final drug product. Additionally, appropriate packaging must be selected and testing and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life.

Submission and FDA Review of an NDA

The results of preclinical studies and clinical trials, together with detailed information on the drug’s manufacture, composition, quality, controls and proposed labeling, among other things, are submitted to the FDA in the form of an NDA, requesting approval to market the drug for one or more indications. The application must be accompanied by a significant user fee payment, which typically increases annually, although waivers may be granted in limited cases. The FDA conducts a preliminary review of all NDAs within the first 60 days after submission, before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA may request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. The FDA has substantial discretion in the approval process and may refuse to file or approve any application or decide that the data are insufficient for approval and require additional preclinical, clinical or other studies.

Once an NDA has been accepted for filing, the FDA sets a user fee goal date that informs the applicant of the specific date by which the FDA intends to complete its review. Under the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act, or PDUFA, the FDA has 10 months from the receipt of an NDA for a non-new molecular entity in which to complete its initial review of a standard NDA and respond to the applicant. The review process can be extended by FDA requests for additional information or clarification. The FDA reviews NDAs to determine, among other things, whether the proposed drug is safe and effective for its intended use, and whether the drug is being manufactured in accordance with cGMPs to assure and preserve the drug’s identity, strength, quality and purity. Before approving an NDA, the FDA typically will inspect the facilities at which the drug is manufactured and will not approve the drug unless the manufacturing facilities comply with cGMPs. Additionally, the FDA will typically inspect one or more clinical trial sites for compliance with GCP and integrity of the data supporting safety and efficacy.

During the approval process, the FDA also will determine whether a REMS is necessary to assure the safe use of the drug. REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe use, or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring and the use of patent registries. If the FDA concludes a REMS is needed, the sponsor of the application must submit a proposed REMS, and the FDA will not approve the application without an approved REMS, if required. A REMS can substantially increase the costs of obtaining approval. The FDA may also convene an advisory committee of external experts to provide input on certain review issues relating to risk, benefit and interpretation of clinical trial data. The FDA may delay approval of an NDA if applicable regulatory criteria are not satisfied and/or the FDA requires additional testing or information.

On the basis of the FDA’s evaluation of the NDA and accompanying information, including the results of the inspection of the manufacturing facilities and clinical trial sites, the FDA will issue either an approval of the NDA or a Complete Response Letter, detailing the deficiencies in the submission and the additional testing or information required for reconsideration of the application. FDA may also issue a Complete Response Letter or defer action on an application if the agency has determined that a pre-approval inspection of an applicant’s manufacturing facilities is necessary and the agency is unable to complete such an inspection due to the COVID-19 pandemic. If a Complete Response Letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, withdraw the application or request a hearing. Even with submission of this additional information, the FDA may ultimately decide that the application does not satisfy the regulatory criteria for approval.

If the FDA approves a new drug, it may limit the approved indications for use of the drug. It may also require that contraindications, warnings or precautions be included in the drug labeling, such as a special warning, known as a boxed warning, to highlight a particular safety risk. In addition, the FDA may call for post-approval studies, including Phase 4 clinical trials, to further assess the drug’s safety after approval. The agency may also require testing and surveillance programs to monitor the drug after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms, including REMS, to help ensure that the benefits of the drug outweigh the potential risks. The FDA may prevent or limit further marketing of a drug based on the results of post-market studies or surveillance programs. After approval, many types of changes to the approved drug, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and approval.

Fast Track and Breakthrough Designations and Priority Review

The FDA is authorized to designate certain drugs for expedited programs, including fast track designation, breakthrough therapy designation, and priority review, if they demonstrate the potential to address an unmet medical need and are intended for the treatment of a serious or life-threatening disease or condition. The purpose of these programs is to provide important new drugs to patients earlier than under standard FDA review procedures.

The FDA may designate a drug for fast track designation if it is intended, whether alone or in combination with one or more other drugs, for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for such a disease or condition. The FDA will determine that a product will fill an unmet medical need if it will provide a therapy where none exists or provide a therapy that may be potentially superior to existing therapy based on efficacy or safety factors. For fast track designated drugs, sponsors may have a higher number of interactions with the FDA during preclinical and clinical development. In addition, the FDA may review sections of the NDA for a fast track designated drug on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA.

A product is eligible for priority review if it has the potential to provide a significant improvement in safety or effectiveness in the treatment, diagnosis or prevention of a serious disease or condition. A priority review means that the goal for the FDA to review an application is six months, rather than the standard review of ten months under current PDUFA guidelines. Under the new PDUFA agreement, these six and ten month review periods are measured from the “filing” date rather than the receipt date for NDAs for new molecular entities, which typically adds approximately two months to the timeline for review and decision from the date of submission. Most products that are eligible for fast track designation are also likely to be considered appropriate to receive a priority review.

The FDA may designate a drug for breakthrough designation if the drug, alone or in combination with one or more other drugs, is intended to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement on a clinically significant endpoint(s) over available therapies. The feature of this program allows the same advantages of the fast track designation, but also intensive FDA guidance to promote efficient development and FDA organizational commitment.

Accelerated Approval Pathway

The FDA may grant accelerated approval to a drug for a serious or life-threatening condition that provides meaningful therapeutic advantage to patients over existing treatments based upon adequate and well-controlled clinical trials establishing that the drug has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit. The FDA may also grant accelerated approval for such a condition when the drug has an effect on an intermediate clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality, or IMM, and that is reasonably likely to predict an effect on IMM or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. Drugs granted accelerated approval must meet the same statutory standards for safety and effectiveness as those granted traditional approval.

For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. Surrogate endpoints can often be measured more easily or more rapidly than clinical endpoints. An intermediate clinical endpoint is a measurement of a therapeutic effect that is considered reasonably likely to predict the clinical benefit of a drug, such as an effect on IMM. The FDA has limited experience with accelerated approvals based on intermediate clinical endpoints, but has indicated that such endpoints generally may support accelerated approval where the therapeutic effect measured by the endpoint is not itself a clinical benefit and basis for traditional approval, if there is a basis for concluding that the therapeutic effect is reasonably likely to predict the ultimate clinical benefit of a drug.

98

Table of Contents

The accelerated approval pathway is most often used in settings in which the course of a disease is long and an extended period of time is required to measure the intended clinical benefit of a drug, even if the effect on the surrogate or intermediate clinical endpoint occurs rapidly. Thus, accelerated approval has been used extensively in the development and approval of drugs for treatment of a variety of cancers in which the goal of therapy is generally to improve survival or decrease morbidity and the duration of the typical disease course requires lengthy and sometimes large trials to demonstrate a clinical or survival benefit. The benefit of accelerated approval derives from the potential to receive approval based on surrogate endpoints sooner than possible for trials with clinical or survival endpoints, rather than deriving from any explicit shortening of the FDA approval timeline, as is the case with priority review.

The accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in a diligent manner, confirmatory studies to verify and describe the drug’s clinical benefit. As a result, a product candidate approved on this basis is subject to rigorous post-marketing compliance requirements, including the completion of Phase 4 or post-approval clinical trials to confirm the effect on the clinical endpoint. Failure to conduct required post-approval studies, or confirm a clinical benefit during post-marketing studies, would allow the FDA to initiate expedited proceedings to withdraw approval of the drug.

All promotional materials for product candidates approved under accelerated regulations are subject to prior review by the FDA.

Post-Approval Requirements

In additional to the post-approval requirements specific to an accelerated approval pathway, there are other post-approval requirements whatever the registration pathway.

Approved drugs that are manufactured or distributed in the United States pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, drug sampling and distribution, advertising and promotion and reporting of adverse experiences with the drug. After approval, most changes to the approved drug, such as adding new indications or other labeling claims and some manufacturing and supplier changes are subject to prior FDA review and approval. There also are continuing, annual program user fee requirements for marketed drugs, as well as new application fees for certain supplemental applications.

The FDA may impose a number of post-approval requirements as a condition of approval of an NDA. For example, the FDA may require post-marketing testing, including Phase 4 clinical trials, and surveillance programs to further assess and monitor the drug’s safety and effectiveness after commercialization. The FDA may also require a REMS, which could involve requirements for, among other things, medication guides, special trainings for prescribers and dispensers, patient registries, and elements to assure safe use.

In addition, entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance with cGMP requirements. The FDA has promulgated specific requirements for drug cGMPs. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP requirements and impose reporting and documentation requirements upon the sponsor and any third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance.

Once an approval is granted, the FDA may issue enforcement letters or withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the drug reaches the market. Corrective action could delay drug distribution and require significant time and financial expenditures. Later discovery of previously unknown problems with a drug, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

restrictions on the marketing or manufacturing of the drug, suspension of the approval, complete withdrawal of the drug from the market or product recalls;
fines, warning letters or holds on post-approval clinical trials;

99

Table of Contents

refusal of the FDA to approve applications or supplements to approved applications, or suspension or revocation of drug approvals;
drug seizure or detention, or refusal to permit the import or export of drugs; or
injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of drugs that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability, including investigation by federal and state authorities.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making available in the United States a drug for this type of disease or condition will be recovered from sales in the United States for that drug. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. The orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process.

If a product that has orphan drug designation subsequently receives the first FDA approval for the indication for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity does not prevent FDA from approving a different product for the same disease or condition, or the same product for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the application user fee. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than or different from the indication for which it received orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

FDA Marketing Exclusivity Provisions for Drugs

Market exclusivity provisions under the FDCA can delay the submission or the approval of certain marketing applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to obtain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not approve or even accept for review an abbreviated new drug application, or ANDA, or a 505(b)(2) NDA, submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same indication as the original innovative drug or for another indication, where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder.

The FDCA alternatively provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for drugs containing the active agent for the original indication or condition of use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Pediatric Studies and Exclusivity

Under the Pediatric Research Equity Act of 2003, as amended, certain NDAs or supplement thereto must contain data that are adequate to assess the safety and effectiveness of the drug for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each pediatric subpopulation for which the drug is safe and effective. Sponsors must also submit pediatric study plans prior to the assessment data. Those plans must contain an outline of the proposed pediatric study or studies the applicant plans to conduct, including study objectives and design, any deferral or waiver requests and other information required by regulation. The applicant, the FDA, and the FDA’s internal review committee must then review the information submitted, consult with each other and agree upon a final plan. The FDA or the applicant may request an amendment to the plan at any time.

The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the drug for use in adults, or full or partial waivers from the pediatric data requirements if certain criteria are met.

Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment of an additional six months of marketing protection to the term of any existing regulatory exclusivity, including the non-patent marketing and orphan exclusivity. This six-month exclusivity may be granted if an NDA sponsor submits pediatric data that fairly respond to a written request from the FDA for such data. The data do not need to show the drug to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of FDA-requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, whatever statutory or regulatory periods of exclusivity or patent protection cover the drug are extended by six months. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot approve another application.

EU Regulation for Drug Development and Registration

Preclinical and Clinical Development

In the EU, our product candidates are also subject to extensive regulatory requirements. As in the United States, medicinal products can only be marketed if a marketing authorization from the competent regulatory agencies has been obtained.

Similar to the United States, the various phases of preclinical and clinical research in the EU are subject to significant regulatory controls. In the EU, clinical trials are governed by the Clinical Trials Regulation (EU) No 536/2014, or CTR, which entered into application on January 31, 2022 repealing and replacing the former Clinical Trials Directive 2001/20, or CTD, and related national legislation of EU Member States. The CTR has been fully applicable to all clinical trials commenced from January 31, 2023.

The CTR is intended to harmonize and streamline clinical trial authorizations, simplify adverse-event reporting procedures, improve the supervision of clinical trials and increasing their transparency. Specifically, the Regulation, which is directly applicable in all EU Member States, introduces a streamlined application procedure through a single-entry point, the “EU portal”, the Clinical Trials Information System, or CTIS; a single set of documents to be prepared and submitted for the application; as well as simplified reporting procedures for clinical trial sponsors. A harmonized procedure for the assessment of applications for clinical trials has been introduced and is divided into two parts. Part I assessment is led by the competent authorities of a reference Member State selected by the trial sponsor and relates to clinical trial aspects that are considered to be scientifically harmonized across EU Member States. This assessment is then submitted to the competent authorities of all concerned Member States in which the trial is to be conducted for their review. Part II is assessed separately by the competent authorities and Ethics Committees in each concerned EU Member State. Individual EU Member States retain the power to authorize the conduct of clinical trials on their territory.

The extent to which on-going clinical trials will be governed by the CTR will depend on the duration of the individual clinical trial. For clinical trials in relation to which application for approval was made on the basis of the CTD before January 31, 2022, the CTD will continue to apply on a transitional basis for three years. These clinical trials will be governed by the CTD until January 31, 2025. By that date, all ongoing trials will become subject to the provisions of the CTR. The CTR will apply to clinical trials from an earlier date if the clinical trial has already transitioned to the CTR framework.

European Drug Review and Approval

To obtain a marketing authorization, or MA, for a product in the EEA (which is comprised of the 27 Member States of the EU plus Norway, Iceland and Liechtenstein), an applicant must submit a marketing authorization application, or MAA, either under a centralized procedure administered by the European Medicines Agency, or EMA, or one of the procedures administered by competent authorities in the EU Member States (decentralized procedure, national procedure or mutual recognition procedure). An MA may be granted only to an applicant established in the EU.

The centralized procedure provides for the grant of a single MA by the EC that is valid for all EU Member States and plus Norway, Iceland and Liechtenstein. Pursuant to Regulation (EC) No 726/2004, the centralized procedure is compulsory for specific products, including for (i) medicinal products derived from biotechnological processes, (ii) products designated as orphan medicinal products, (iii) advanced therapy medicinal products (ATMPs), and (iv) products with a new active substance indicated for the treatment of HIV/AIDS, cancer, neurodegenerative diseases, diabetes, auto-immune and other immune dysfunctions and viral diseases. For products with a new active substance indicated for the treatment of other diseases and products that are highly innovative or for which a centralized process is in the interest of patients authorization through, the centralized procedure is optional on related approval.

Under the centralized procedure, the EMA’s Committee for Medicinal Products for Human Use (CHMP) is responsible for conducting the initial assessment of a product. The CHMP is also responsible for several post-authorization and maintenance activities, such as the assessment of modifications or extensions to an existing MA.

Under the centralized procedure in the EU, the maximum timeframe for the evaluation of an MAA is 210 days, excluding clock stops when additional information or written or oral explanation is to be provided by the applicant in response to questions of the CHMP. Accelerated assessment may be granted by the CHMP in exceptional cases, when a medicinal product targeting an unmet medical need is expected to be of major interest from the point of view of public health and, in particular, from the viewpoint of therapeutic innovation. If the CHMP accepts a request for accelerated assessment, the time limit of 210 days will be reduced to 150 days (not including clock stops). The CHMP can, however, revert to the standard time limit for the centralized procedure if it considers that it is no longer appropriate to conduct an accelerated assessment.

Unlike the centralized authorization procedure, the decentralized MA procedure requires a separate application to, and leads to separate approval by, the competent authorities of each EU Member State in which the product is to be marketed. This application process is the same as the application that would be submitted to the EMA for authorization through the centralized procedure. The reference EU Member State prepares a draft assessment and drafts of the related materials within 120 days after receipt of a valid application. The resulting assessment report is submitted to the concerned EU Member States who, within 90 days of receipt, must decide whether to approve the assessment report and related materials. If a concerned EU Member State cannot approve the assessment report and related materials due to concerns relating to a potential serious risk to public health, disputed elements may be referred to the Heads of Medicines Agencies’ Coordination Group for Mutual Recognition and Decentralized Procedures – Human (CMDh) for review. The subsequent related decision of the EC is binding on all EU Member States.

The mutual recognition procedure allows companies that have a medicinal product already authorized in one EU Member State to apply for this authorization to be recognized by the competent authorities in other EU Member States. Like the decentralized procedure, the mutual recognition procedure is based on the acceptance by the competent authorities of the EU Member States of the MA of a medicinal product by the competent authorities of other EU Member States. The holder of a national MA may submit an application to the competent authority of an EU Member State requesting that this authority recognize the MA delivered by the competent authority of another EU Member State.

102

Table of Contents

An MA has an initial validity of five years in principle. The MA may be renewed after five years on the basis of a re-evaluation of the risk-benefit balance by the EMA or by the competent authority of the EU Member State in which the original MA was granted. To support the application, the MA holder must provide the EMA or the competent authority with a consolidated version of the eCTD (Common Technical Document) providing up-to-date data concerning the quality, safety and efficacy of the product, including all variations introduced since the MA was granted, at least nine months before the MA ceases to be valid. The EC or the competent authorities of the EU Member States may decide, on justified grounds relating to pharmacovigilance, to proceed with one further five year renewal period for the MA. Once subsequently definitively renewed, the MA shall be valid for an unlimited period. Any authorization which is not followed by the actual placing of the medicinal product on the EU market (for a centralized MA) or on the market of the authorizing EU Member State within three years after authorization ceases to be valid (the so-called sunset clause).

Innovative products that target an unmet medical need and are expected to be of major public health interest may be eligible for a number of expedited development and review programs, such as the Priority Medicines, or PRIME, scheme, which provides incentives similar to the breakthrough therapy designation in the US PRIME is a voluntary scheme aimed at enhancing the EMA’s support for the development of medicinal products that target unmet medical needs. Eligible products must target conditions for which there is an unmet medical need (there is no satisfactory method of diagnosis, prevention or treatment in the EU or, if there is, the new medicinal product will bring a major therapeutic advantage) and they must demonstrate the potential to address the unmet medical need by introducing new methods of therapy or improving existing ones. Benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and potentially accelerated MAA assessment once a dossier has been submitted.

Within this framework, manufacturers may seek approval of medicinal products under the hybrid application pathway in accordance with Article 10(3) of Directive 2001/83/EC. Hybrid MAAs rely, in part, on information and data from a reference product and new data from appropriate pre-clinical tests and clinical trials. In accordance with Article 10(3) of Directive 2001/83/EC, hybrid applications are relevant in cases where the medicinal product does not fall within the definition of a generic medicinal product, where bioequivalence cannot be demonstrated through bioavailability studies, or in case of changes in the active substance(s), therapeutic indications, strength, pharmaceutical form or route of administration of the generic product compared to the reference medicinal product. In such cases the results of tests and trials must be consistent with the data content standards required in the Annex to Directive 2001/83/EC. Hybrid MAAs have automatic access to the centralized procedure when the reference product was authorized for marketing via that procedure. Where the reference product was authorized through the national, mutual recognition or decentralized procedure, a hybrid application may be accepted for consideration under the centralized procedure if the applicant shows that the medicinal product constitutes a significant therapeutic, scientific or technical innovation, or that grant of a centralized authorization for the medicinal product is in the interest of patients at the EU level.

In the EU, a “conditional” MA may be granted in cases where all the required safety and efficacy data are not yet available. The EC may grant a conditional MA for a medicinal product if it is demonstrated that all of the following criteria are met: (i) the benefit-risk balance of the medicinal product is positive; (ii) it is likely that the applicant will be able to provide comprehensive data post-authorization; (iii) the medicinal product fulfils an unmet medical need; and (iv) the benefit of the immediate availability to patients of the medicinal product is greater than the risk inherent in the fact that additional data are still required. The conditional MA is subject to conditions to be fulfilled for generating the missing data or ensuring increased safety measures. It is valid for one year and must be renewed annually until all related conditions have been fulfilled. Once any pending studies are provided, the conditional MA can be converted into a traditional MA. However, if the conditions are not fulfilled within the timeframe set by the EMA and approved by the EC, the MA will cease to be renewed.

An MA may also be granted “under exceptional circumstances” where the applicant can show that it is unable to provide comprehensive data on efficacy and safety under normal conditions of use even after the product has been authorized and subject to specific procedures being introduced. These circumstances may arise in particular when the intended indications are very rare and, in the state of scientific knowledge at that time, it is not possible to provide comprehensive information, or when generating data may be contrary to generally accepted ethical principles. Like a conditional MA, an MA granted in exceptional circumstances is reserved to medicinal products intended to be authorized for treatment of rare diseases or unmet medical needs for which the applicant does not hold a complete data set that is required for the grant of a standard MA. However, unlike the conditional MA, an applicant for authorization in exceptional circumstances is not subsequently required to provide the missing data. Although the MA “under exceptional circumstances” is granted definitively, the risk-benefit balance of the medicinal product is reviewed annually, and the MA will be withdrawn if the risk-benefit ratio is no longer favorable.

In addition to an MA, various other requirements apply to the manufacturing and placing on the EU market of medicinal products. Manufacture of medicinal products in the EU requires a manufacturing authorization, and import of medicinal products into the EU requires a manufacturing authorization allowing for import. The manufacturing authorization holder must comply with various requirements set out in the applicable EU and national EU Member State laws, regulations and guidance. These requirements include compliance with EU GMP standards when manufacturing medicinal products and APIs, including the manufacture of APIs outside of the EU with the intention to import the APIs into the EU. Similarly, the distribution of medicinal products within the EU is subject to compliance with the applicable EU and national EU Member State laws, regulations and guidelines, including the requirement to hold appropriate authorizations for distribution granted by the competent authorities of the EU Member States. MA holders and/or manufacturing and import authorization, or MIA holders and/or distribution authorization holders may be subject to civil, criminal or administrative sanctions, including suspension of manufacturing authorization, in case of non-compliance with the EU or EU Member States’ requirements applicable to the manufacturing of medicinal products.

Orphan Drugs

In the EU, Regulation (EC) No 141/2000, as amended, provides that a drug will be designated as an orphan drug if its sponsor can establish:

that it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition and either (i) such condition affects not more than five in ten thousand persons in the EU when the application is made, or (ii) without incentives it is unlikely that the marketing of the drug in the EU would generate sufficient return to justify the necessary investment in its development; and
that there exists no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been authorized in the EU or, if such method exists, that the drug will be of significant benefit to those affected by that condition.

Regulation (EC) No 847/2000 sets out further provisions for implementation of the criteria for designation of a drug as an orphan drug. An application for the designation of a drug as an orphan drug must be submitted at any stage of development of the drug but before filing of a MA application. A MA for an orphan drug may only include indications designated as orphan. For non-orphan indications treated with the same active pharmaceutical ingredient, a separate MA has to be sought.

If a centralized MA in respect of an orphan drug is granted pursuant to Regulation (EC) No 726/2004, regulatory authorities will not, for a period of usually 10 years, accept another application for a MA, or grant a MA or accept an application to extend an existing MA, for the same therapeutic indication, in respect of a “similar medicinal product”. A “similar medicinal product” is defined as a medicinal product containing a similar active substance or substances as contained in an authorized orphan medicinal product, and which is intended for the same therapeutic indication. This period may however be reduced to six years if, at the end of the fifth year, it is established, in respect of the drug concerned, that the criteria for orphan drug designation are no longer met, in other words, when it is shown on the basis of available evidence that the product is sufficiently profitable not to justify maintenance of market exclusivity.

The exclusivity period may increase to 12 years if the MA application includes the results of studies from an agreed pediatric investigation plan. Notwithstanding the foregoing, a MA may be granted, for the same therapeutic indication, to a similar medicinal product if:

the holder of the MA for the original orphan drug has given its consent to the second applicant;
the holder of the MA for the original orphan drug is unable to supply sufficient quantities of the drug; or
the second applicant can establish in the application that the second drug, although similar to the orphan drug already authorized, is safer, more effective or otherwise clinically superior.

The EC is currently looking into the experience gathered with the orphan and pediatric regulations and may propose changes to the incentives and rewards as they exist today. The EC submitted its proposal in March 2023.

Table of Contents

Regulation (EC) No 847/2000 lays down definitions of the concepts ‘similar drug’ and ‘clinical superiority’. Other incentives available to orphan drugs in the EU include financial incentives such as a reduction of fees or fee waivers and protocol assistance. Orphan drug designation in itself does not shorten the duration of the regulatory review and approval process but an applicant’s request for an accelerated review may be granted in case the medicinal product is of major interest from the point of view of public health and in particular from the viewpoint of therapeutic innovation.

Data and marketing exclusivity

The EEA also provides opportunities for market exclusivity. Upon receiving a marketing authorization in the EEA, innovative medicinal products generally receive eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents generic or biosimilar applicants from referencing the innovator’s pre-clinical and clinical trial data contained in the dossier of the reference product when applying for a generic or biosimilar marketing authorization during a period of eight years from the date on which the reference product was first authorized in the EEA. During the additional two-year period of market exclusivity, a generic or biosimilar marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic or biosimilar product can be marketed until the expiration of the market exclusivity period. The overall ten-year period will be extended to a maximum of eleven years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to authorization, is held to bring a significant clinical benefit in comparison with existing therapies.

Regulatory Requirements after Marketing Authorization

Where an MA is granted in relation to a medicinal product in the EU, the holder of the MA is required to comply with a range of regulatory requirements applicable to the manufacturing, marketing, promotion and sale of medicinal products.

Similar to the United States, both MA holders and manufacturers of medicinal products are subject to comprehensive regulatory oversight by the EMA, the EC and/or the competent regulatory authorities of the individual EU Member States. The holder of an MA must establish and maintain a pharmacovigilance system and appoint an individual qualified person for pharmacovigilance who is responsible for oversight of that system. Key obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports, or PSURs.

All new MAAs must include a risk management plan, or RMP, describing the risk management system that the company will put in place and documenting measures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the MA. Such risk-minimization measures or post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or the conduct of additional clinical trials or post-authorization safety studies.

Advertising Regulation

In the EU, the advertising and promotion of medicinal products are subject to both EU and EU Member States’ laws governing promotion of medicinal products, interactions with physicians and other healthcare professionals, misleading and comparative advertising and unfair commercial practices. General requirements for advertising and promotion of medicinal products, such as direct-to-consumer advertising of prescription medicinal products are established in EU law. However, the details are governed by regulations in individual EU Member States and can differ from one country to another. For example, applicable laws require that promotional materials and advertising in relation to medicinal products comply with the product’s Summary of Product Characteristics, or SmPC, which may require approval by the competent national authorities in connection with an MA. The SmPC is the document that provides information to physicians concerning the safe and effective use of the product. Promotional activity that does not comply with the SmPC is considered off-label and is prohibited in the EU.

Coverage, Pricing, and Reimbursement

Significant uncertainty exists in the United States as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. Sales of our products will depend, in part, on the extent to which our products, once approved, will be covered and reimbursed by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. Adequate coverage and reimbursement from third party payors are critical to new product acceptance. In the United States, the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid Services, or CMS, an agency within the US Department of Health and Human Services, or HHS. CMS decides whether and to what extent our products will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree.

Our ability to commercialize any products successfully also will depend in part on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from third party payors. Third-party payors decide which therapeutics they will pay for and establish reimbursement levels. These third-party payors are increasingly reducing reimbursement levels for medical products and services. The process for determining whether a third-party payor will provide coverage for a drug product typically is separate from the process for setting the price of a drug product or for establishing the reimbursement rate that a payor will pay for the drug product once coverage is approved. Third-party payors may limit coverage to specific drug products on an approved list, also known as a formulary, which might not include all of the approved drugs for a particular indication. Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that use of a therapeutic is:

a covered benefit under its health plan;
safe, effective and medically necessary;
appropriate for the specific patient;
cost-effective; and
neither experimental nor investigational.

To secure coverage and reimbursement for any product candidate approved for sale, we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product candidate, in addition to the costs required to obtain FDA or other comparable regulatory approvals. Whether or not we conduct such studies, our product candidates may not be considered medically necessary or cost-effective. A third-party payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Additionally, companies may also need to provide discounts to purchasers, private health plans or government healthcare programs. Further, no uniform policy for coverage and reimbursement exists in the United States, and coverage and reimbursement can differ significantly from payor to payor. One payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product. Further, coverage policies and third-party payor reimbursement rates may change at any time. Therefore, even if favorable coverage and reimbursement status is attained, less favorable coverage policies and reimbursement rates may be implemented in the future. Third-party reimbursement may not be sufficient to enable us to realize an appropriate return on our investment in product development.

The containment of healthcare costs has become a priority of federal, state and foreign governments, and the prices of drugs have been a focus in this effort. The United States federal government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement, utilization management and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. Decreases in third-party reimbursement for Nefecon or any of our product candidates, if approved, or a decision by a third-party payor to not cover such products could reduce physician usage of the product and could have a material adverse effect on our sales, results of operations and financial condition.

106

Table of Contents

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, in the EU Member States can restrict the range of medicinal products for which their national health insurance systems provide reimbursement and they can control the prices of medicinal products for human use. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost effectiveness of a particular product candidate to currently available therapies. A Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. Approaches between Member States are diverging. For example, in France, effective market access will be supported by agreements with hospitals and products may be reimbursed by the Social Security Fund. The price of medicines is negotiated with the Economic Committee for Health Products, or CEPS. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our product candidates. Historically, products launched in the EU do not follow price structures of the United States and generally prices tend to be significantly lower.

The marketability of any product candidates for which we receive regulatory approval for commercial sale may suffer if third party payors fail to provide coverage and adequate reimbursement. In addition, emphasis on managed care, the increasing influence of health maintenance organizations, and additional legislative changes in the United States has increased, and we expect will continue to increase, the pressure on healthcare pricing. The downward pressure on the rise in healthcare costs in general, particularly prescription medicines, medical devices and surgical procedures and other treatments, has become very intense. Coverage policies and third party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

On December 15, 2021, the Health Technology Regulation, or HTA Regulation, was adopted. The HTA Regulation is intended to boost cooperation among EU member states in assessing health technologies, including new medicinal products, and providing the basis for cooperation at EU level for joint clinical assessments in these areas. When it enters into application in 2025, the HTA Regulation will be intended to harmonize the clinical benefit assessment of HTA across the European Union.

Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect the ability to profitably sell product candidates for which marketing approval is obtained. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, ACA, enacted in the United States in March 2010, has already had, and is expected to continue to have, a significant impact on the healthcare industry. The ACA has expanded coverage for the uninsured while at the same time containing overall healthcare costs. With regard to pharmaceutical products, among other things, the ACA: (i) created an annual, nondeductible fee on entities that manufacture or import certain branded pharmaceutical products; (ii) expanded and increased industry rebates for drugs covered under Medicaid programs; and (iii) made changes to the coverage requirements under the Medicare Part D program, including a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

107

Table of Contents

Since its enactment, there have been numerous judicial, administrative, executive, and legislative challenges to certain aspects of the ACA. On June 17, 2021, the United States Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which, among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. Litigation and legislation related to the ACA are likely to continue, with unpredictable and uncertain results.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For example, on August 2, 2011, the Budget Control Act of 2011 among other things, created measures for spending reductions by Congress. Specifically, the Joint Select Committee on Deficit Reduction was created to recommend to Congress proposals in spending reductions. The Joint Select Committee on Deficit Reduction did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2012 through 2021, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, started in April 2013 and which, due to subsequent legislative amendments will stay in effect through 2032 unless additional Congressional action is taken. Additionally, on March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. Further, on January 2, 2013, former President Obama signed into law the American Taxpayer Relief Act of 2012, or the ATRA. The ATRA, among other things, reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

Recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products. Such scrutiny has resulted in several recent US Congressional inquiries, Presidential executive orders and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under Medicare and reform government program reimbursement methodologies for drug products. At the federal level, in July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue to advance these principles. In addition, the IRA, among other things, (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs and biologics covered under Medicare Part B or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions take effect progressively starting in fiscal year 2023, although they may be subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. In response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the Centers for Medicare & Medicaid Services, (“CMS”), Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve the quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, on January 5, 2024, the FDA approved Florida’s Section 804 Importation Program (SIP) proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products covered by those programs.

Brexit and the Regulatory Framework in the UK

The United Kingdom’s, or UK, withdrawal from the EU on January 31, 2020, commonly referred to as Brexit, has changed the regulatory relationship between the UK and the EU. The Medicines and Healthcare products Regulatory Agency, or MHRA, is now the UK’s standalone regulator for medicinal products and medical devices. Great Britain (England, Scotland and Wales) is now a third country to the EU. Northern Ireland will, with regard to EU regulations, continue to follow the EU regulatory rules for now.

Among the changes that have occurred are that Great Britain (England, Scotland and Wales) is now considered a “third country,” a country that is not a member of the EU and whose citizens do not enjoy the EU right to free movement. Northern Ireland will continue to follow many aspects of the EU regulatory rules, particularly in relation to trade in goods.

Marketing authorizations in the UK are now governed by the Human Medicines Regulations (SI 2012/1916), as amended. Since January 1, 2021, an applicant for the EU centralized procedure marketing authorization can no longer be established in the UK. As a result, since this date, companies established in the UK cannot use the EU centralized procedure and instead must follow one of the UK national authorization procedures or one of the remaining post-Brexit international cooperation procedures to obtain a marketing authorization to market products in the UK. All existing EU marketing authorizations for centrally authorized products were automatically converted or grandfathered into UK marketing authorization, effective in Great Britain only, free of charge on January 1, 2021, unless the marketing authorization holder opted-out of this possibility. Northern Ireland currently remains within the scope of EU authorizations in relation to centrally authorized medicinal products. Accordingly, until the Windsor Framework is implemented in Northern Ireland on January 1, 2025, products falling within the scope of the EU centralized procedure can only be authorized through UK national authorization procedures in Great Britain.

The MHRA has also introduced changes to national marketing authorization procedures. This includes introduction of procedures to prioritize access to new medicines that will benefit patients, including a 150-day assessment route, a rolling review procedure and the International Recognition Procedures which entered into application on January 1, 2024. Since January 1, 2024, the MHRA may also rely on the International Recognition Procedure, or IRP, when reviewing certain types of marketing authorization applications. This procedure is available for applicants for marketing authorization who have already received an authorization for the same product from a reference regulator. These include the FDA, the EMA, and national competent authorities of individual EEA countries. A positive opinion from the EMA and CHMP, or a positive end of procedure outcome from the mutual recognition or decentralized procedures are considered to be authorizations for the purposes of the IRP.

There is no pre-marketing authorization orphan designation for medicinal products in the UK. Instead, the MHRA reviews applications for orphan designation in parallel to the corresponding marketing authorization application. The criteria are essentially the same as those in the EU, but have been tailored for the market. This includes the criterion that prevalence of the condition in Great Britain, rather than the EU, must not be more than five in 10,000. Upon the grant of a marketing authorization with orphan status, the medicinal product will benefit from up to 10 years of market exclusivity from similar products in the approved orphan indication. The start of this market exclusivity period will be set from the date of first approval of the product in Great Britain.

The UK regulatory framework in relation to clinical trials is derived from existing EU legislation (as implemented into UK law, through secondary legislation). However, it is currently unclear to what extent the UK will seek to align its regulations with the EU following entry into application of the Clinical Trials Regulation on January 31, 2022.

It is currently unclear what the UK regulatory arrangements will be in the future. The MHRA have taken steps to build relationships and partnerships with other global regulators such as joining the ACCESS group (Canada, Australia, Switzerland and Singapore) and taking part in Project Orbis, which is an FDA-led project. The future regulatory system and these partnerships may provide alternative routes to market in the UK and beyond.

Other US Healthcare Laws and Compliance Requirements

Our business operations in the United States and our arrangements with clinical investigators, healthcare providers, consultants, third-party payors and patients expose us to broadly applicable federal and state fraud and abuse and other healthcare laws. These laws may impact, among other things, our research, sales, marketing and education programs. The laws that may affect our ability to operate include, among others:

the US federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully soliciting, receiving, offering or paying remuneration (including any kickback, bribe or rebate), directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, lease, order, or recommendation of, an item, good, facility or service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs. The term remuneration has been interpreted broadly to include anything of value. The federal Anti-Kickback Statute has been interpreted to apply to arrangements between manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. A violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act, or FCA;
federal civil and criminal false claims laws, including the FCA, which can be enforced by private individuals through civil whistleblower or qui tam actions, and civil monetary penalty laws, which prohibit individuals and entities from, among other things, knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent, or making a false statement or record material to payment of a false claim or avoiding, decreasing, or concealing an obligation to pay money to the federal government, including for example, providing inaccurate billing or coding information to customers or promoting a product off-label;
the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created additional federal criminal statutes that prohibit knowingly and willfully executing or attempting to execute a scheme to defraud any healthcare benefit program, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willingly falsifying, concealing or covering up a material fact or making materially false statements, fictitious, or fraudulent statements in connection with the delivery of or payment for healthcare benefits, items, or services. A person or entity does not have to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementing regulations, which imposes certain requirements on certain healthcare providers, health plans, and healthcare clearinghouses, known as covered entities, and their business associates, which are individuals and entities that perform functions or activities on behalf of covered entities that involve protected health information as well as their covered subcontractors, relating to the privacy, security and transmission of protected health information; HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorneys’ fees and costs associated with pursuing federal civil actions;
the federal Physician Payments Sunshine Act, enacted as part of the ACA, which requires applicable manufacturers of drugs for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to track and annually report to CMS payments and other transfers of value provided to physicians (as defined by such law), other healthcare professionals (such as physicians assistants and nurse practitioners) and teaching hospitals and certain ownership and investment interests held by physicians and their immediate family members; and

110

Table of Contents

state and foreign equivalents of each of the above federal laws and regulations, such as: state anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers; state and local marketing and/or transparency laws applicable to manufacturers that may be broader in scope than the federal requirements; state laws that require the reporting of information related to drug pricing; state laws that require biopharmaceutical companies to comply with the biopharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government; state and local laws that require the registration of pharmaceutical sales representatives; and state and/or foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect as HIPAA, thus complicating compliance efforts.

The ACA broadened the reach of the federal fraud and abuse laws by, among other things, amending the intent requirement of the US federal Anti-Kickback Statute and certain federal criminal healthcare fraud statutes. Pursuant to the statutory amendment, a person or entity no longer needs to have actual knowledge of these statutes or specific intent to violate them in order to have committed a violation. In addition, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the US federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the FCA or the civil monetary penalties laws.

In the ordinary course of our business, we may process personal or sensitive data. We may be subject to numerous data privacy and security obligations, including federal, state, local, and foreign laws, regulations, guidance, and industry standards related to data privacy, security, and protection. Such obligations may include, without limitation, HIPAA, as amended by HITECH, and their implementing regulations, the California Consumer Privacy Act of 2018 (“CCPA”), the European Union’s General Data Protection Regulation 2016/679 (“EU GDPR”), the EU GDPR as it forms part of United Kingdom (“UK”) law by virtue of section 3 of the European Union (Withdrawal) Act 2018 (“UK GDPR”), and the ePrivacy Directive. Several states within the United States have enacted or proposed data privacy laws. For example, Virginia passed the Consumer Data Protection Act, and Colorado passed the Colorado Privacy Act. Additionally, we are, or may become, subject to various U.S. federal and state consumer protection laws which require us to publish statements that accurately and fairly describe how we handle personal data and choices individuals may have about the way we handle their personal data. The CCPA and EU GDPR are examples of the increasingly stringent and evolving regulatory frameworks related to personal data processing that may increase our compliance obligations and exposure for any noncompliance.

We may develop products that, once approved, may be administered by a physician. Under currently applicable US law, certain products not usually self-administered (including injectable drugs) may be eligible for coverage under Medicare through Medicare Part B. Medicare Part B is part of original Medicare, the federal health care program that provides health care benefits to the aged and disabled, and covers outpatient services and supplies, including certain pharmaceutical products, that are medically necessary to treat a beneficiary’s health condition. As a condition of receiving Medicare Part B reimbursement for a manufacturer’s eligible drugs, the manufacturer is required to participate in other government healthcare programs, including the Medicaid Drug Rebate Program and the 340B Drug Pricing Program. The Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the Secretary of HHS as a condition for states to receive federal matching funds for the manufacturer’s outpatient drugs furnished to Medicaid patients. Under the 340B Drug Pricing Program, the manufacturer must extend discounts to entities that participate in the program.

In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales price, or ASP, and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely. Further, these prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors.

In order to distribute any approved products commercially, we must comply with state laws that require the registration of manufacturers and wholesale distributors of drug and biological products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical and biotechnology companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical and biotechnology companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

Efforts to ensure that our business arrangements with third parties comply with applicable healthcare laws involves substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to, for example, significant administrative, civil, and/or criminal penalties, damages, fines, disgorgement, contractual damages, reputational harm, diminished profits and future earnings, imprisonment, exclusion from government funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws and the curtailment or restructuring of our operations. If the physicians or other healthcare providers or entities with whom we expect to do business are found to be not in compliance with applicable laws, they may be subject to administrative, civil, and/or criminal sanctions, including exclusions from government funded healthcare programs.

Employees and Human Capital Resources

As of December 31, 2023, we had 217 full-time employee equivalents. We consider our relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. Other objectives include diversity and inclusion, employee development, training and safety. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors through the granting of stock-based compensation awards.

None of our personnel are covered by a collective bargaining agreement. Collective bargaining agreements, or CBAs, can be entered into in Swedish law at the national, industry, or company levels. These CBAs are binding on both employers and employees. We have no trade union representation or CBAs at the company level, but CBAs may, however, change the employment conditions of our employees in the future and hence adversely affect our employment relationships.

Facilities

Our principal office is located at Kungsbron 1, D5, SE-111 22 Stockholm, Sweden. We lease approximately 1,552 square meters of office space at this location, under one lease agreement, and our lease for this location extends through December 31, 2026. We hold an option to extend our leases for three additional years. We believe that suitable additional or substitute space will be available as needed to accommodate any future expansion of our operations.

ITEM 5.OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following “Operating and Financial Review and Prospects” should be read together with the information in our financial statements and related notes included elsewhere in this annual report. The following discussion is based on our financial information prepared in accordance with the International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or IASB, which may differ in material respects from generally accepted accounting principles in other jurisdictions, including US GAAP. The following discussion includes forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including but not limited to those described in “Risk Factors” and elsewhere in this annual report. Please also see “Special Note Regarding Forward-Looking Statements.”

A.OPERATING RESULTS

Overview

We are a commercial-stage pharmaceutical company with the first ever product approved in the US and in the EU for adult patients with the renal disease immunoglobulin A nephropathy, or IgAN, Nefecon, and a portfolio of innovative product candidates.

113

Table of Contents

Nefecon is a proprietary, novel oral, delayed release formulation of budesonide designed to specifically target the presumed origin of the disease and provide a potentially disease modifying treatment of IgAN, for which there is a high unmet medical need. Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity that undergoes substantial first pass metabolism, resulting in limited systemic exposure. IgAN is a progressive, chronic disease that over time results in deterioration of kidney function in patients, many of whom are at risk of developing ESRD, with the need for dialysis or kidney transplant. Nefecon is designed to target the origin of the disease presumed to be located in the ileum, the distal region of the small intestine, which has the highest concentration of the Peyer’s patches, which are responsible for the production of pathogenic secretory immunoglobulin A, or IgA, antibodies.

The US Food and Drug Administration, or FDA, approved Nefecon under the brand name TARPEYO under accelerated approval on December 15, 2021 and we reported commercial availability in the United States in January 2022. Under accelerated approval, the indication for TARPEYO (budesonide) delayed release capsules (4mg) is reduction of proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a urine protein-to-creatinine ratio, or UPCR, ≥1.5gram/gram. In June 2023, we submitted a supplemental New Drug Application, or sNDA, to the FDA seeking to convert the accelerated approval to full approval for TARPEYO. On December 20, 2023, the FDA granted full approval to TARPEYO for a new indication to reduce the loss of kidney function in adults with IgAN who are at risk for disease progression. The European Commission, or EC, granted conditional marketing authorization for Nefecon under the name Kinpeygo (budesonide) capsules for the treatment of primary IgAN in adults at risk of rapid disease progression with a UPCR ≥1.5 gram/gram on July 15, 2022 and our licensee STADA Arzneimittel AG, or STADA, announced commercial availability in Germany in September 2022, and in Greece, under a Special Import License since June 2023. On February 1, 2023, the Medicines and Healthcare products Regulatory Agency, or MHRA, of the UK granted Conditional Marketing Authorization for Kinpeygo for the same indication as the EC. STADA has submitted requests to both the EMA, in September 2023, for the EU and to the MHRA, in October 2023, for the UK to convert the current conditional marketing authorization for these territories into a full marketing authorization. Nefecon received conditional approval from China’s National Medical Products Administration on November 24, 2023 for the reduction of proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a UPCR, ≥1.5gram/gram and approval from the Pharmaceutical Administration Bureau of the Macau Special Administrative Region on October 27, 2023 for the same indication. Nefecon received conditional approval from Singapore’s Health Science Agency for the reduction of proteinuria in adults with IgAN at risk of rapid disease progression, generally a UPCR ≥1.5 gram/gram to on March 19, 2024.

TARPEYO was the first treatment ever approved for the US market indicated for patients with IgAN. The FDA approved TARPEYO under the accelerated approval pathway based on the reduction in proteinuria and supportive data on the estimated Glomerular Filtration Rate, or eGFR, a measure of kidney function, shown in Part A of our pivotal NefIgArd trial. We reported topline results from the full NefIgArd clinical trial in March 2023. The trial met its primary endpoint with Nefecon demonstrating a highly statistically significant benefit over placebo (p value < 0.0001) in eGFR over the two-year period of nine months of treatment with Nefecon or placebo and 15 months of follow-up off drug. The results indicate that Nefecon was generally well-tolerated and the safety profile was consistent with that observed in Part A of the trial. These results were the basis for the June 2023 sNDA submission to the FDA to convert the accelerated approval to full approval for TARPEYO.

Nefecon as TARPEYO was initially granted seven years orphan drug exclusivity in the United States, expiry December 15, 2028, which was recently extended to December 2030 based on receiving full approval. Kinpeygo, was granted ten years orphan market exclusivity by the EC, expiry July 15, 2032, and by the MHRA, expiring February 1, 2033.

We retain worldwide rights to Nefecon other than in territories where we have established strategic collaborations. In 2019, we entered into an agreement pursuant to which we granted Everest an exclusive license to develop and commercialize Nefecon for the treatment of IgAN in Greater China and Singapore, and in March 2022, we expanded the territory covered by the agreement to include the Republic of Korea. In July 2021, we entered into a license agreement with STADA to commercialize Nefecon for the treatment of IgAN in the European Economic Area, or EEA, the UK and, if approved, in Switzerland. In December 2022, we entered into an exclusive license agreement with Viatris, to register and commercialize Nefecon for the treatment of IgAN in Japan.

We are also developing a novel platform of nicotinamide adenine dinucleotide phosphate, or NADPH, oxidase, or NOX, inhibitors, which we intend to primarily develop for orphan diseases with fibrotic pathology, with a main focus on kidney and liver diseases. From this platform, we are developing setanaxib, a NOX inhibitor, for the treatment of primary biliary cholangitis, or PBC. We are currently evaluating setanaxib in the TRANSFORM study, a Phase 2b clinical trial, in which we randomized the first patient in February 2022. Setanaxib will be administered to approximately 60-70 patients with PBC and elevated liver stiffness as well as intolerance or inadequate response to ursodeoxycholic acid, a generic drug also known as ursodiol or UDCA in a global trial conducted in 80-130 investigational centers in North America, Europe, Israel, Australia, and New Zealand. The primary endpoint is alkaline phosphatase (ALP) reduction, with key secondary endpoints including change in liver stiffness and effect on fatigue and pruritus (itching). Following favorable safety data from a Phase 1 study, this trial will evaluate two dosing regimens of 1200mg/daily and 1600mg/daily. We expect to read out data in the third quarter of 2024, and this analysis will determine which dose of setanaxib will be used for a future potential Phase 3 study. Setanaxib was granted fast track designation by the FDA in August 2021. We are also conducting a proof of concept, Phase 2 clinical trial of setanaxib administered in conjunction with pembrolizumab, a check point inhibitor, in squamous cell carcinoma of the head and neck, or SCCHN, in order to explore setanaxib’s use as a treatment approach in cancers with high levels of tumors associated fibroblasts, or CAFs. We are also currently conducting a Phase 2 clinical trial of setanaxib in Alport syndrome, which we initiated in November 2023.

Since our inception in 2004, we have devoted substantially all of our resources to conducting research and development of our product candidates, in-licensing and acquiring rights to our product candidates, business planning, building a US commercial operation, launching Nefecon in the US, raising capital and providing general and administrative support for our operations. To date, we have financed our operations primarily with proceeds from the sale of our equity, the upfront and milestone payments from the out-license of Nefecon to Everest, STADA, and Viatris, our debt facility with Athyrium, which we fully drew down and used part of the proceeds from the Credit Agreement to repay in full outstanding obligations under our loan agreement with Kreos and, more recently, from revenue from sales of TARPEYO. Through December 31, 2023, we had received net proceeds of SEK 2,523.8 million from the issuance of equity securities. In August 2021, we completed a directed new share issuance of 2.4 million shares for gross proceeds of SEK 324.0 million from Swedish and international institutional investors. In June and July 2020, we completed a new share issuance of 9.2 million shares, in connection with the initial public offering of our securities on Nasdaq (the “US IPO”) and concurrent private placement, for gross proceeds of SEK 891.4 million from US and international institutional investors. In July 2019, we completed a directed new share issuance of 3.5 million shares for gross proceeds of SEK 210.3 million from Swedish and international institutional investors. We believe that our cash as of December 31, 2023 will be sufficient to fund our planned operations and capital expenditure requirements until we are profitable. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. There can be no assurance that Nefecon will be approved by additional regulatory authorities, or that we will be successful in commercializing TARPEYO in the United States, Kinpeygo in the EEA and UK, Nefecon in China and Macau, NEFEGAN in Singapore, or Nefecon in other jurisdictions, if approved. See “Item 3.D.—Risk Factors—Risks Related to Our Financial Position and Need for Additional Capital—We may need substantial additional funding in order to fund our operations. Failure to obtain this necessary capital at acceptable terms and when needed may force us to delay, limit or terminate certain or all of our operations and pursuit of our growth strategy.”

We have incurred significant operating losses since our inception in 2004. For the years ended December 31, 2023 and 2022, we had a net loss of SEK 466.2 million and SEK 412.3 million, respectively. As of December 31, 2023 and 2022, we had an accumulated loss of SEK 2,305.6 million and SEK 1,836.3 million, respectively. These losses have resulted primarily from costs incurred in connection with research and development activities and administrative and selling activities associated with our operations. We expect to continue to incur significant expenses and may continue to incur operating losses for the foreseeable future, and we expect our expenses to increase in connection with our ongoing development activities and our activities related to developing our commercialization capabilities to support sales, marketing and distribution activities, either independently or in collaboration with others.

Until such time as we can generate increased revenue from product sales and royalties and milestones from our commercial partnerships to cover our costs, if ever, we expect to finance our operations through a combination of equity offerings, debt financings, collaborations, or other strategic transactions.

We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back, or discontinue the development and commercialization of one or more of our development programs.

License Agreement with Everest

In 2019, we entered into a license agreement with Everest, pursuant to which we granted Everest an exclusive, royalty-bearing, non-transferable license to develop, manufacture and commercialize Nefecon for IgAN, which at Everest’s option, may be extended to other potential indications if and when we initiate a registrational clinical trial in such indications, which we collectively refer to as the Licensed Product. The territories covered by the Everest license are Greater China, including mainland China, Taiwan, Hong Kong and Macau, the Republic of Korea and Singapore, which we collectively refer to as the Territories. In March 2022, we announced the expansion of the Territories to include the Republic of Korea.

Under the terms of the agreement, we received an initial upfront payment of $15.0 million upon signing the agreement and in March 2022 in connection with the expansion of the agreement, we received an additional upfront payment of $3.0 million. Additionally, as of December 2023, Everest has paid us an aggregate of $21 million in regulatory milestones and is obligated to pay us additional milestone payments of up to $85 million upon achievement of specified regulatory and commercial milestones. Everest is also required to pay typical tiered royalties on annual net sales of the Licensed Product, subject to customary reductions. See “Item 4.B.—Business Overview—License Agreement with Everest.”

License Agreement with STADA

In 2021, we entered into a license agreement with STADA, pursuant to which we granted STADA an exclusive, royalty-bearing, non-transferable license to develop, manufacture and commercialize Nefecon for IgAN in the EEA, Switzerland and the UK.

Under the terms of the agreement, we received an initial upfront payment of EUR 20.0 million upon signing the agreement, two milestones totaling EUR 12.5 million and we are eligible to receive future payments upon the satisfaction of specific regulatory and commercial milestones of up to an additional EUR 65.0 million, inclusive of option payments for the development of Nefecon in other potential indications. STADA is also required to pay typical tiered royalties on net sales expressed as a percentage between the low twenties and the low thirties. See “Item 4.B.—Business Overview—License Agreement with STADA.”

License Agreement with Viatris

In December 2022, we entered into a license agreement with Viatris, pursuant to which we granted Viatris an exclusive, royalty-bearing, non-transferable license to develop, manufacture and commercialize Nefecon for IgAN in Japan.

Under the terms of the agreement, we received an initial upfront payment of $20 million upon signing the agreement, and we are eligible to receive future payments upon the satisfaction of specific development and commercial milestones of up to an additional $80 million. Viatris is also required to pay typical mid-teens percentage royalties on net sales. See “Item 4.B.—Business Overview—License Agreement with Viatris.”

Acquisition of a Controlling Interest in Genkyotex S.A.

In November 2020, we acquired a controlling interest in Genkyotex S.A., or Genkyotex, a biopharmaceutical company specializing in NOX therapies with offices in France and Switzerland. Genkyotex’s unique platform enables the identification of orally available small molecules which selectively inhibit specific NOX enzymes that amplify multiple disease processes such as fibrosis and inflammation. The acquisition of Genkyotex adds a late-stage orphan pipeline asset and platform in inflammation and fibrosis to our product portfolio in orphan diseases. In October 2021, we completed the purchase of the remaining share capital of Genkyotex by a squeeze-out offer, resulting in our ownership of 100% of the current share capital and the delisting of Genkyotex’s securities from the Euronext stock exchanges.

Table of Contents

We had no acquisition costs related to Genkyotex for the years ended December 31, 2022 and 2023. For the year ending December 31, 2021, acquisition costs related to Genkyotex, excluding transaction costs, amounted to EUR 4.9 million. In addition, in connection with the business combination, we have undertaken to make potential future milestone payments relating to contingent consideration, provided that future regulatory approvals or marketing authorizations regarding setanaxib are obtained.

Components of our Results of Operations

Revenue

In the first quarter of 2022, we launched our first commercial product, TARPEYO, in the United States and began to generate revenue from product sales. Revenue from product sales is recognized at the transaction price of goods sold excluding VAT, rebates and returns. At the time of delivery, when the control of the goods passes to the customer, the revenue is recognized in full, as this represents the single performance obligation in the transaction. The customer is defined as the specialty pharmacy who dispenses the good to the end user. As the final price is related to the rebate paid to the patients’ insurance company, the transaction price is not known upon delivery. This is accounted for by an accrued estimated rebate deduction based on calculation models considering statistical data, actual amounts incurred and/or historical trends. These liabilities for expected returns and rebates are based on estimates of the amounts earned or to be claimed on the related sales. Furthermore, we estimate the liability for expected returns of obsolete medicines that is recognized in the accounts.

In 2021, we recognized revenue in connection with the execution of the license agreement with STADA and additionally upon triggering payments to us resulting from the satisfaction of a regulatory milestone under the Everest agreement. In 2022, we recognized revenue in connection with the execution of the license agreement with Viatris and additionally upon triggering payments to us resulting from the satisfaction of regulatory milestones under the Everest and STADA agreements, and we are eligible to receive future payments upon the satisfaction of specific clinical, regulatory and commercial milestones, as well as typical tiered royalties from these agreements. In 2023, we recognized revenue resulting from the satisfaction of regulatory milestones under the license agreement with Everest and we recognized revenues from tiered royalties from the license agreements with STADA and Everest. Revenue for license agreements is recognized at a point in time, which occurs when control over the intangible asset is transferred to the counterparty, which was at the time when the agreements with the parties were signed. Variable remuneration (for example, attributable to future regulatory milestones) is recognized when there is no longer any significant uncertainty as to whether these will occur. Compensation attributable to sales-based milestones or royalties are not recognized until the sale that results in the right to milestones or royalties arises.

We refer to revenue received from product sales and from our license agreements with Viatris, Everest and STADA as “net sales” in our consolidated financial statements. In addition to sales of Nefecon, we may generate revenue in the future from a combination of product sales and collaboration or license agreements, if our development programs for Nefecon, setanaxib and future product candidates are successful and result in approved and marketed products, or if we enter into additional collaboration or license agreements with third parties.

Cost of Sales

Cost of sales includes the cost of inventory sold, labor costs, manufacturing overhead expenses and reserves for expected scrap, as well as shipping and freight costs. Cost of sales also includes royalty costs related to in-license agreements.

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our development activities, including the development of Nefecon, setanaxib and our other product candidates, and include:

expenses incurred under agreements with third parties, including contract research organizations, or CROs, that conduct clinical trials on our behalf, as well as contract manufacturing organizations, or CMOs, that manufacture drug products for use in our clinical trials;
salaries, benefits and other related costs for our personnel engaged in research and development functions;
costs of outside consultants, including their fees and related travel expenses, directly related to our research and development functions; and
costs related to compliance with regulatory requirements.

We expense research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our financial statements as a prepaid expense or accrued expense. Swedish research and development tax credits on social security costs are recorded as an offset to research and development expense. See “—Income Taxes” below for further details.

From inception until October 2020, our research and development expenses were primarily for the development of Nefecon for the treatment of IgAN and from October 2020 through December 31, 2023, our research and development expenses have primarily been for the development of Nefecon for the treatment of IgAN and the setanaxib platform. As such, we do not track our internal research and development expenses on a product-by-product or indication-by-indication basis for product candidates. Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect that our research and development expenses will continue to increase as we:

continue to develop and advance Nefecon, setanaxib, and any other product candidates;
initiate and continue clinical development for Nefecon and setanaxib for PBC, head and neck cancer and Alport syndrome and other potential indications;
seek regulatory approvals for Nefecon, setanaxib and/or any product candidates that successfully complete clinical trials;
continue to build a sales, marketing and distribution infrastructure and scale-up external manufacturing to commercialize Nefecon and any other present or future product candidates that receive approval;
maintain, expand and protect our intellectual property portfolio, including litigation costs associated with defending against alleged patent infringement claims;
continue to add clinical and scientific personnel, including personnel to support our product development and potential future commercialization efforts;
seek to expand our development pipeline, including through potential in-licensing opportunities and strategic acquisitions;
expand our operations in the United States and Europe; and

experience any delays or encounter any issues with regards to any of the above, including, but not limited to, failed studies, ambiguous trial results, safety issues or other regulatory challenges, including any unforeseen costs we may incur as a result of clinical trial or supply chain delays or other business interruptions due to health pandemics, geopolitical tensions or other world events.

The process of conducting the necessary clinical trials to obtain regulatory approval is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

We also expect to incur additional expenses related to milestone and royalty payments payable to third parties with whom we have entered into license agreements. See “Item 5.B.—Liquidity and Capital Resources—Contractual Obligations and Commitments.”

Marketing and Selling Expenses

Marketing and selling expenses consist of salaries and other related costs for personnel in our commercialization functions including our field sales force, marketing and other commercial support personnel. Marketing and selling expenses also include professional fees and related costs for our marketing program.

We expect that our marketing and selling expenses will increase in the future as we increase our headcount and expand our marketing program to support our commercialization of Nefecon and potential commercialization of our portfolio of product candidates.

Administrative Expenses

Administrative expenses consist of salaries and other related costs for personnel in our executive, finance, corporate and business development and administrative functions. Administrative expenses also include professional fees for legal, intellectual property, accounting, auditing, tax and consulting services, public entity listing costs related travel expenses and facility-related expenses, which include expenses for rent and maintenance of facilities and other operating costs.

We expect that our administrative expenses will increase in the future as we increase our headcount to support our continued development and commercialization of Nefecon and potential commercialization of our portfolio of product candidates. We also expect to continue to incur increased expenses associated with being a dual-listed public company in the United States and Sweden, including costs of accounting, audit, legal, regulatory and tax compliance services, director and officer insurance costs and investor and public relations costs.

Other Operating Income

Other operating income consists primarily of realized and unrealized foreign currency transaction gains on operating receivables and liabilities.

Other Operating Expenses

Other operating expenses consist primarily of realized and unrealized foreign currency transaction losses on operating receivables and liabilities.

Financial Income

Financial income consists primarily of interest income earned on cash accounts and realized and unrealized foreign currency transaction gains on financial receivables and liabilities.

Financial Expenses

Financial expenses consist primarily of interest rate expenses and realized and unrealized foreign currency transaction losses on financial receivables and liabilities.

Income Tax

We are subject to corporate taxation in Sweden and taxation in the United States, France and Switzerland for our subsidiaries. Due to the nature of our business, we have generated losses since inception and have therefore not paid Swedish corporation tax to date. The research and development tax credit on social security costs for personnel within research and development received in Sweden and France is recorded as a credit against research and development expenses. The Swedish and France research and development tax credit on social security costs for personnel within research and development is fully refundable to us and is not dependent on current or future taxable income.

As of December 31, 2023, we had SEK 3,881.3 million of tax losses carried forward for which deferred tax assets have not been recognized in the statement of financial position other than to the extent such tax losses can be used to offset temporary differences. Deferred tax assets will be recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized.

Table of Contents

Research and Development Expenses

Research and development expenses increased by SEK 87.5 million for the year ended December 31, 2023 compared to the year ended December 31, 2022. This increase was primarily due to increased costs of SEK 59.2 million for the setanaxib clinical trials. The cost related to the Nefecon clinical trials decreased by SEK 32.6 million. Included in the increase for the full year, was the recognition of a one-time effect from the impairment of SEK 32.1 million regarding in-licensing of Budenofalk.

Marketing and Selling Expenses

Marketing and selling expenses increased by SEK 212.5 million for the year ended December 31, 2023 compared to the year ended December 31, 2022.

B.LIQUIDITY AND CAPITAL RESOURCES

Sources of Funds

To date, we have financed our operations primarily with proceeds from the sale of our equity, the upfront payments and related milestone payments from the out-license of Nefecon to Everest, STADA, and Viatris, our debt facility with Athyrium (described below), which we fully drew down and used part of the proceeds from the Credit Agreement to repay in full outstanding obligations under our loan agreement with Kreos and, more recently, from revenue from sales of TARPEYO. In 2021, we recognized revenue in connection with the execution of the license agreement with STADA and additionally upon triggering payments to us resulting from the satisfaction of a regulatory milestone under the Everest agreement. In 2022, we recognized revenue in connection with the execution of the license agreement with Viatris and additionally upon triggering payments to us resulting from the satisfaction of regulatory and clinical milestones under the Everest and STADA agreements, and we are eligible to receive future payments upon the satisfaction of specific clinical, regulatory and commercial milestones, as well as typical tiered royalties from these agreements. In 2023, we recognized revenue resulting from the satisfaction of regulatory milestones under the license agreement with Everest and we recognized revenues from tiered royalties from the license agreements with STADA and Everest. We refer to revenue received from our license agreement with Everest, STADA and Viatris as “net sales” in our consolidated financial statements. In addition to sales of Nefecon, we may generate revenue in the future from a combination of product sales and collaboration or license agreements, if the development programs for Nefecon, setanaxib and future product candidates are successful and result in approved and marketed products, or if we enter into additional collaboration or license agreements with third parties.

Table of Contents

Through December 31, 2023, we had received net proceeds of SEK 2,523.8 million from the issuance of equity securities. In August 2021, we completed a directed new share issuance of 2.4 million shares for gross proceeds of SEK 324.0 million from Swedish and international institutional investors. In June and July 2020, we completed a new share issuance of 9.2 million shares, in connection with the US IPO and concurrent private placement, for gross proceeds of SEK 891.4 million from US and international institutional investors. In July 2019, we completed a directed new share issuance of 3.5 million shares for gross proceeds of SEK 210.3 million from Swedish and international institutional investors. We believe that our cash as of December 31, 2023 will be sufficient to fund our planned operations and capital expenditure requirements until we are profitable. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. There can be no assurance that Nefecon will be approved by additional regulatory authorities, or that we and our commercialization partners will successfully commercialize Nefecon in the jurisdictions in which it is approved. See “Item 3.D.—Risk Factors—Risks Related to Our Financial Position and Need for Additional Capital—We may need substantial additional funding in order to fund our operations. Failure to obtain this necessary capital at acceptable terms and when needed may force us to delay, limit or terminate certain or all of our operations and pursuit of our growth strategy.”

In December 2023, we entered into a credit agreement with Athyrium pursuant to which Athyrium made available to us 92 million Euros, which we fully drew down. We used part of the proceeds from the Credit Agreement to repay in full outstanding obligations under our loan agreement with Kreos Capital VI (UK) Limited and Kreos Capital 2020 Opportunity (UK) Limited. The interest rate on the loan is 9% per annum with a maturity of December 2027. The Credit Agreement contains financial covenants to maintain minimum unrestricted cash (including cash equivalents) and achieve minimum net revenue targets with respect to Nefecon. The Credit Agreement contains affirmative and negative covenants customary for a senior secured loan. The negative covenants under the Credit Agreement limit our and our subsidiaries’ abilities to, among other things, dispose of assets, engage in mergers, acquisitions, and similar transactions, incur additional indebtedness, grant liens, make investments, pay dividends or make distributions or certain other restricted payments in respect of equity, prepay other indebtedness, enter into restrictive agreements, undertake fundamental changes or amend certain material contracts, in each case subject to certain exceptions. The Credit Agreement also contains certain customary events of default, including, but not limited to, a failure to comply with the covenants in the Credit Agreement. If an event of default has occurred and continues beyond any applicable cure period, the administrative agent or the required lenders may accelerate all outstanding obligations under the Credit Agreement and/or exercise any other remedies provided under the loan documents. Other than the Athyrium Credit Agreement and our lease obligations described below under “Item 5.B.—Liquidity and Capital Resources—Contractual Obligations and Commitments,” we have no ongoing material financing commitments, such as lines of credit or guarantees, that are expected to affect our liquidity over the next five years.

In July 2022, we entered into an Open Market Sale AgreementSM, or the Sales Agreement, with Jefferies, under which we may, at our option, offer and sell ADSs having an aggregate offering price of up to $75.0 million from time to time through Jefferies, acting as sales agent. As of the date of this report, we have not sold any shares pursuant to the Sales Agreement. The Sales Agreement was terminated in June 2023. We did not sell any shares pursuant to the Sales Agreement prior to its termination.

Ukraine

The February 2022 invasion of Ukraine by Russia, the resulting military conflict and retaliatory measures by the United States, UK, the EU, and others in the global community have created global security concerns, including the possibility of expanded regional or global conflict, which have had, are likely to continue to have, short-term and likely longer-term adverse impacts on Ukraine and Europe and around the globe. Potential ramifications include disruption of the supply chain including research activities and complications with the conduct of ongoing and future clinical trials. It is not possible to predict the broader or longer-term consequences of this armed conflict, which could include further sanctions, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, security conditions, currency exchange rates and financial markets. Such geo-political instability and uncertainty could materially affect our business and the value of our common shares and our ability to raise capital if and when needed.

During the year ended December 31, 2021, net cash used in operating activities was SEK 461.6 million, primarily resulting from our operating loss of SEK 524.5 million and adjustment for non-cash items of SEK 66.7 million and negative net cash changes in our operating assets and liabilities of SEK 5.5 million.

Investing Activities

During the year ended December 31, 2022, net cash used for investing activities was SEK 5.1 million primarily related to investment in fixed assets and rental deposits.

During the year ended December 31, 2021, net cash used for investing activities was SEK 24.3 million primarily related to a EUR 1.5 million milestone payment for the Budenofalk license.

Financing Activities

During the year ended December 31, 2022, net cash provided by financing activities was SEK 576.0 million primarily related to SEK 491.7 million from the drawdown of tranche 2 and 3 of the Kreos loan facility and SEK 95.1 million from exercise of warrant programs.

During the year ended December 31, 2021, net cash provided by financing activities was SEK 435.2 million from a new share issue of net SEK 304.0 million and the drawdown of the first tranche of the Kreos loan facility of net SEK 199.5 million, reduced by SEK 49.3 million used in a simplified public mandatory cash offer of Genkyotex SA.

Funding Requirements

We expect our expenses to increase substantially in connection with our ongoing activities. We may need additional funds to meet operational needs and capital requirements for our commercialization activities, clinical trials, other research and development expenditures, and business development activities. Because of the numerous risks and uncertainties associated with pharmaceutical product development and commercialization, we are unable to accurately predict the timing or amount of increased expenses and our product sales or when, or if, we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

Table of Contents

We believe that our cash as of December 31, 2023 will be sufficient to fund our planned operations and capital expenditure requirements until we are profitable. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. There can be no assurance that Nefecon will be approved by additional regulatory authorities, or successfully commercialized, if and where approved. See “Item 3.D.—Risk Factors—Risks Related to Our Financial Position and Need for Additional Capital—We may need substantial additional funding in order to fund our operations. Failure to obtain this necessary capital at acceptable terms and when needed may force us to delay, limit or terminate certain or all of our operations and pursuit of our growth strategy.”

Because of the numerous risks and uncertainties associated with the development of product candidates and programs, and because the extent to which we may enter into collaborations with third parties for development of our product candidates is unknown, we are unable to estimate the timing and amounts of increased capital outlays and operating expenses associated with completing the research and development of our product candidates. Our future capital requirements will depend on many factors, including:

the scope, progress, results and costs of researching and developing our product candidates and conducting preclinical studies and clinical trials;
the costs, timing and outcome of regulatory review of our product candidates;
the costs and timing of launching and commercializing product candidates for which we obtain regulatory and marketing approval, including acquiring sales force, marketing and distribution infrastructure or, alternatively, collaborating with a commercialization partner;
the amount of revenue from sales of TARPEYO in the United States, Kinpeygo in the EEA and UK, and Nefecon in China, Macau and Singapore and other jurisdictions, if approved;
the costs and timing of completing development of our product candidates and in-licensing or otherwise acquiring new product candidates;
our ability to qualify for and maintain adequate coverage and reimbursement by government and payors for our product candidates for which we obtain marketing approval;
the costs of establishing and maintaining supply and manufacturing processes and relationships with third parties that can provide adequate, in both amount and quality, products and services to support clinical development of our product candidates and the commercial supply of our product candidates for which we obtain marketing approval;
our success in obtaining market acceptance of our product candidates, if approved, as viable treatment options with acceptable safety profiles;
our ability to address any competing technological and market developments;
the timing and costs of implementing additional internal systems and infrastructure, as needed, including robust quality systems and compliance systems;
our success in negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter and performing our obligations under such arrangements;
the timing, receipt and amount of sales of, or milestone payments related to or royalties on, our current or future products and product candidates;
the costs associated with maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and know-how; and
the costs of attracting, hiring and retaining qualified personnel.

Table of Contents

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our operations through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements. If we undertake financing arrangements in the future, the terms of any financing may adversely affect the holdings or the rights of holders of our common shares or ADSs and the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of the ADSs to decline. The sale of additional equity or convertible securities would dilute all of our existing shareholders and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a holder of ADSs. The incurrence of indebtedness could result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. We could also be required to seek funds through arrangements with collaborators or others at an earlier stage than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, financial condition and results of operations. Further, any additional fundraising efforts may divert our management from its day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates.

Contractual Obligations and Commitments

Our lease obligations primarily comprise our leased premises. The total lease obligations for 0-5 years were SEK 65.0 million as of December 31, 2023. The lease agreements for leased premises have terms ending from 2024 until 2027 and can be extended unless one of the parties terminates the lease agreements.

In July 2021, we signed a loan agreement of up to the euro equivalent of USD 75.0 million with Kreos Capital. The loan facility was divided into three tranches of USD 25.0 million each. Drawdown of the first USD 25 million tranche was made in September 2021, drawdown of the second USD 25 million tranche was made in June 2022, and drawdown of the third and final tranche was made in December 2022. The interest rate on the loan was 9% per annum with a maturity to December 2025. The loan had no financial covenants. In December 2023, the loan was fully repaid.

In December 2023, we entered into a credit agreement with Athyrium, pursuant to which Athyrium made available to us 92 million Euros, which we fully drew down. The interest rate on the loan is 9% per annum with a maturity of December 2027. The Credit Agreement contains financial covenants to maintain minimum unrestricted cash (including cash equivalents) and achieve minimum net revenue targets with respect to Nefecon. The Credit Agreement contains affirmative and negative covenants customary for a senior secured loan.

We enter into contracts in the normal course of business with CROs and CMOs and other third parties for clinical trials and manufacturing. There are no obligations associated with cancellation provisions, non-cancelable portions of agreement terms or minimum cancellation fees.

License Agreements with Archimedes

We are required to pay Kyowa Kirin Services Ltd., f/k/a Archimedes Development Ltd, or Archimedes, a fixed royalty of 3% of net sales of Nefecon, including TARPEYO sales in the United States and in other jurisdictions, if approved, covered by the license granted to us pursuant to our agreement with Archimedes pursuant to which we were granted (i) an exclusive license to certain patents and joint intellectual property developed with Archimedes and (ii) a non-exclusive license to certain of Archimedes’ know-how as necessary or useful to develop and commercialize Nefecon or other product candidates.

Due to the uncertainty of the achievement and timing of the events requiring various payments under these agreements, the amounts to be paid by us are not fixed or determinable at this time and are excluded from the table above.

D.TREND INFORMATION

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events for the period from January 1, 2023 to December 31, 2023 that are reasonably likely to have a material effect on our net revenues, income, profitability, liquidity or capital resources, or that caused the disclosed financial information to be not necessarily indicative of future operating results or financial conditions. For a discussion of trends, see the sections of this annual report titled “Item 4.B.—Business Overview,” “Item 5.A.—Operating Results”, and “Item 5.B.—Liquidity and Capital Resources.”

E.CRITICAL ACCOUNTING ESTIMATES

Our consolidated financial statements for the years ended December 31, 2021, 2022 and 2023, have been prepared in accordance with IFRS as issued by the IASB. See Notes 1 and 2 to our consolidated financial statements appearing at the end of this annual report for a description of our significant accounting judgements and estimates.

The preparation of the consolidated financial statements requires us to make judgements, estimates and assumptions that affect the value of assets and liabilities—as well as contingent assets and liabilities—as reported on the statement of financial position date, and revenues and expenses arising during the fiscal year.

The estimates and associated assumptions are based on information available when the consolidated financial statements are prepared, historical experience and various other factors which are believed to be reasonable under the circumstances, the results of which form the basis of making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising that are beyond our control. Hence, estimates may vary from the actual values.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or the period of revision and future periods if this revision affects both current and future periods.

Recently Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted

A description of recently adopted accounting pronouncements and accounting pronouncements not yet adopted that may potentially impact our financial position and results of operations is disclosed in our consolidated financial statements appearing at the end of this annual report.

Under the rules and regulations of Nasdaq a director will qualify as “independent” if our board of directors affirmatively determines that he or she has no material relationship with us (either directly or as a partner, stockholder or officer of an organization that has a relationship with us). Our board of directors has determined that, of our six directors, no director has a relationship that would interfere with the exercise of independent judgment in carrying out his or her responsibilities as a director and that each of these directors is “independent” as that term is defined under Nasdaq rules. The Swedish Code includes certain independence requirements for the directors, and requires a majority of the directors to be independent of the company and at least two directors to also be independent of major shareholders.

The following is the biographical information of the members of our board of directors:

Equity Incentive Plans

ESOP 2020

The ESOP 2020 is a program under which participants will be granted stock options to acquire common shares in our company. As of December 31, 2023, options to purchase up to an aggregate of 1,364,730 common shares were outstanding. Eligible participants in the ESOP 2020 include our executive officers, employees and consultants. The ESOP 2020 Program is closed for allocation, and no further options may be issued under this program.

The options under the ESOP 2020 are granted for no consideration, though grantees must pay the exercise price of such options to acquire their underlying common shares. The options generally will vest over a three-year period, with 20% vesting on the date of the first anniversary of the grant date, an additional 40% vesting during the second year following the grant date and the remaining 40% vesting during the third year following the grant date. The exercise price of the options will be set at 115% of the volume-weighted average price of the common shares on Nasdaq Stockholm during the ten trading days preceding each grant date. Following the conclusion of the vesting period, the options may be exercised during a one-year period thereafter. The options are not transferrable and may not be pledged. The number of options are subject to customary adjustment for corporate events affecting our capital structure, including a bonus issue, merger, rights issue, share split, reverse share split, reduction of share capital or similar measures. In the event of a public takeover offer, significant asset sale, liquidation, merger or similar transaction, all then unvested options will vest in their entirety following the completion of such transaction.

Our board of directors is responsible for preparing the detailed terms and conditions of the ESOP 2020, in accordance with the terms and guidelines of the ESOP 2020 approved by the shareholders. To this end, our board of directors shall be entitled to make adjustments to meet foreign regulations or market conditions, including resolving on cash or other settlement if deemed favorable for us based on foreign tax regulations. In particular, personnel in the United States may participate in the ESOP 2020 as modified by a US sub-plan. Options granted under the US sub-plan will vest in accordance with the schedules determined by our board of directors at the time of grant. All options granted under the US sub-plan will be classified as “non-qualified stock options” under US federal tax laws. No options granted under the US sub-plan will be exercisable more than four years following the date on which such options were granted (subject to earlier expiration as provided in the ESOP 2020 or the optionee’s award agreement). Any adjustments to the number of options and the applicable exercise price are permitted only to the extent and in a manner that complies with Section 409A of the US Internal Revenue Code.

ESOP 2021

The ESOP 2021 is a program under which participants will be granted stock options to acquire common shares in our company. As of December 31, 2022, options to purchase up to an aggregate of 1,434,500 common shares were outstanding. Eligible participants in the ESOP 2021 include our executive officers, employees and consultants. The ESOP 2021 Program is closed for allocation, and no further options may be issued under this program.

The options under the ESOP 2021 are granted for no consideration, though grantees must pay the exercise price of such options to acquire their underlying common shares. The options generally will vest over a three-year period, with 20% vesting on the date of the first anniversary of the grant date, an additional 40% vesting during the second year following the grant date and the remaining 40% vesting during the third year following the grant date. The exercise price of the options will be set at 115% of the volume-weighted average price of the common shares on Nasdaq Stockholm during the ten trading days preceding each grant date. Following the conclusion of the vesting period, the options may be exercised during a one-year period thereafter. The options are not transferrable and may not be pledged. The number of options is subject to customary adjustment for corporate events affecting our capital structure, including a bonus issue, merger, rights issue, share split, reverse share split, reduction of share capital or similar measures. In the event of a public takeover offer, significant asset sale, liquidation, merger or similar transaction, all then unvested options will vest in their entirety following the completion of such transaction.

Insurance and Indemnification

To the extent permitted by the Swedish Companies Act, we are empowered to indemnify our directors against any liability they incur by reason of their directorship. We maintain directors’ and officers’ insurance to insure such persons against certain liabilities.

Insofar as indemnification of liabilities arising under the Securities Act may be permitted to our board of directors, executive officers, or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

C.BOARD PRACTICES

Director Independence

As a foreign private issuer, under the listing requirements and rules of Nasdaq, we are not required to have independent directors on our board of directors, except that our audit committee is required to consist fully of independent directors, subject to certain phase-in schedules. However, our board of directors has determined that, under current listing requirements and rules of Nasdaq and taking into account any applicable committee independence standards, all of our six directors are “independent directors.” In making such determination, our board of directors considered the relationships that each non-executive director has with us and all other facts and circumstances our board of directors deemed relevant in determining the director’s independence, including the number of common shares beneficially owned by the director and his or her affiliated entities (if any). The Swedish Corporate Governance Code, or the Swedish Code, includes certain independence requirements for the directors, and requires a majority of the directors to be independent of the company and its management and at least two directors independent of the company and its management to also be independent of major shareholders.

Role of the Board in Risk Oversight

Our board of directors is responsible for the oversight of our risk management activities and has delegated to the audit committee the responsibility to assist our board in this task. While our board oversees our risk management, our management is responsible for day-to-day risk management processes. Our board of directors expects our management to consider risk and risk management in each business decision, to proactively develop and monitor risk management strategies and processes for day-to-day activities and to effectively implement risk management strategies adopted by the board of directors. We believe this division of responsibilities is the most effective approach for addressing the risks we face.

138

Table of Contents

Composition of Our Board of Directors

Our board of directors is currently composed of six members. Under the rules and regulations of Nasdaq a director will qualify as “independent” if our board of directors affirmatively determines that he or she has no material relationship with us (either directly or as a partner, stockholder or officer of an organization that has a relationship with us). Our board of directors has determined that, of our six directors, no director has a relationship that would interfere with the exercise of independent judgment in carrying out his or her responsibilities as a director and that each of these directors is “independent” as that term is defined under Nasdaq rules. The Swedish Code includes certain independence requirements for the directors and requires a majority of the directors to be independent of the company and its management and at least two directors independent of the company and its management to also be independent of major shareholders.

Our board of directors performs its duties in accordance with the rules of procedure of the board of directors. The rules of procedure are reviewed and adopted by the board of directors annually. Our board of directors, including the chairman is elected by our shareholders at the annual general meeting up until the end of the next annual general meeting, with the possibility of re-election. In addition, our employees may, pursuant to statutory rules regarding the representation of employees on the board of directors, elect employee representatives to the board of directors. Currently the board of directors has no employee representatives. The majority of our board members are considered to be independent under the corporate governance standards of Nasdaq and Nasdaq Stockholm.

The meeting attendance rate for our directors is set out in the table below:

Committees of Our Board of Directors

Our board of directors has two standing committees: an audit committee and a remuneration committee.

Audit Committee

Our audit committee currently consists of Fred Driscoll, Hilde Furberg and Henrik Stenqvist, and assists the board of directors in overseeing our accounting and financial reporting processes. Henrik Stenqvist serves as chairperson of the audit committee.

The audit committee consists exclusively of members of our board who are financially literate, and Henrik Stenqvist and Fred Driscoll are each considered an “audit committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable Nasdaq rules and regulations. Our board of directors has determined that all of the members of the audit committee satisfy the “independence” requirements set forth in Rule 10A-3 under the Exchange Act.

The audit committee is governed by a charter that complies with Nasdaq rules. The audit committee’s responsibilities include:

monitoring our financial reporting;
monitoring the efficiency of our internal controls, internal auditing and risk management;
keeping informed of the auditing of the annual report and the consolidated accounts; and
reviewing and monitoring the impartiality and independence of our auditors and paying close attention to whether our auditors are providing other services besides audit services for us.

139

Table of Contents

Our audit committee reports regularly to our board of directors on the exercise of its functions. It informs our board of directors about all areas in which action or improvement is necessary in its opinion and produces recommendations concerning the necessary steps that need to be taken. The audit review and the reporting on that review cover us and our subsidiaries as a whole. The members of the audit committee are entitled to receive all information which they need for the performance of their function, from our board of directors and employees. Every member of the audit committee shall exercise this right in consultation with the chairperson of the audit committee.

The audit committee has deliberated eleven times in the course of 2023. At these meetings, the main points of discussion were review of the 2022 financial statements, Ernst & Young AB’s 2022 audit report, 2023 audit fee proposal, review of interim consolidated financial statements, Ernst & Young AB’s report on interim financial statements, updates on internal control activities including SOX remediation, updates on corporate audit activities and review of the 2024 budget.

Remuneration Committee

Our remuneration committee consists of Diane Parks, Elmar Schnee and Elisabeth Bjork. Elmar Schnee serves as chairman of the remuneration committee.

The Remuneration committee’s responsibilities include:

identifying, reviewing and proposing policies relevant to the compensation and benefits of our executive officers;
reviewing and approving each executive officer’s compensation in light of such policies and reporting to the board; and
overseeing and administering our employee share option scheme or equity incentive plans in operation from time to time.

The remuneration committee has deliberated five times over the course of 2023. The main topics of discussion were management performance reviews, allocation of share-based incentive programs, and 2023 management targets and management remuneration proposals.

Nomination Committee

We are following the Swedish Code of Corporate Governance, or the Swedish Code, and are therefore required to have a nomination committee, which is not a standing committee of our board of directors. According to the Swedish Code, the general meeting shall appoint the members of the nomination committee or resolve on procedures for appointing the members. Such procedures were adopted by our 2023 annual general meeting. The nomination committee shall, pursuant to the Swedish Code, consist of at least three members of which a majority shall be independent in relation to us and our management. In addition, at least one member of the nomination committee shall be independent in relation to the largest shareholder in terms of voting rights or group of shareholders who cooperates in terms of our management.

Ahead of the 2024 annual general meeting, the nomination committee consists of Patrick Sobocki (appointed by Stiftelsen Industrifonden), Spike Loy (appointed by BVF), Karl Tobieson (appointed by Linc AB) and Elmar Schnee (chairman of our board of directors). Karl Tobieson serves as chairman of the nomination committee.

The nomination committee’s responsibilities include:

preparing a proposal for the election of a chairman of the board of directors, the members of the board of directors, the election of a chairman of the annual general meeting, election of auditors, the determination of fees to board members and auditors, and matters pertaining thereto.

Corporate Governance Practices

We are a “foreign private issuer,” as defined by the SEC. As a result, in accordance with Nasdaq listing requirements, we may rely on home country governance requirements and certain exemptions thereunder rather than complying with Nasdaq corporate governance standards. While we may choose to voluntarily follow some Nasdaq corporate governance rules, we may choose to take advantage of the following limited exemptions:

exemption from filing quarterly reports on Form 10-Q containing unaudited financial and other specified information or current reports on Form 8-K upon the occurrence of specified significant events;
exemption from Section 16 rules requiring insiders to file public reports of their securities ownership and trading activities and providing for liability for insiders who profit from trades in a short period of time;
exemption from the Nasdaq requirement necessitating disclosure of any waivers of the Code of Business Conduct and Ethics for directors and executive officers;
exemption from the requirement to obtain shareholder approval for certain issuances of securities, including shareholder approval of share option plans and equity issuances;
exemption from the requirement that our audit committee have review and oversight responsibilities over all “related party transactions,” as defined in Item 7.B of Form 20-F;
exemption from the requirement that our board of directors have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and
exemption from the requirement to have independent director oversight of director nominations.

Furthermore, Nasdaq Rule 5615(a)(3) provides that a foreign private issuer may rely on home country corporate governance practices in lieu of certain of the rules in the Nasdaq Rule 5600 Series and Rule 5250(d). We intend to follow Swedish corporate governance practices in lieu of Nasdaq corporate governance requirements as follows:

We do not intend to follow Nasdaq Rule 5620(c) regarding quorum requirements applicable to meetings of shareholders. Such quorum requirements are not required under Swedish law. The Swedish Companies Act (SFS 2005:551) and our articles of association, which were approved by our shareholders on May 19, 2022 and are currently in effect, provide alternative quorum requirements that are generally applicable to meetings of shareholders.
We do not intend to follow Nasdaq Rule 5605(b)(2), which requires that independent directors regularly meet in executive sessions where only independent directors are present. Our independent directors may choose to meet in executive sessions at their discretion.
We do not intend to follow Nasdaq Rule 5605(e) regarding the composition of the nominating committee.

Although we may rely on certain home country corporate governance practices, we must comply with Nasdaq’s Notification of Noncompliance requirement (Nasdaq Rule 5625) and the Voting Rights requirement (Nasdaq Rule 5640). Further, we must have an audit committee that satisfies Nasdaq Rule 5605(c)(3), which addresses audit committee responsibilities and authority and requires that the audit committee consist of members who meet the independence requirements of Nasdaq Rule 5605(c)(2)(A)(ii).

Because we are a foreign private issuer, our directors and executive officers are not subject to short-swing profit and insider trading reporting obligations under Section 16 of the Exchange Act. They will, however, be subject to the obligations to report changes in securities ownership under Section 13 of the Exchange Act and related SEC rules.

We intend to take all actions necessary for us to maintain compliance as a foreign private issuer under the applicable corporate governance requirements of the Sarbanes-Oxley Act, the rules adopted by the SEC and Nasdaq listing rules.

ITEM 7.MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A.MAJOR SHAREHOLDERS

The following table sets forth information with respect to the beneficial ownership of our common shares as of February 29, 2024 for:

each person who is known by us to own beneficially more than 5% of our total outstanding common shares;
each member of our board of directors and our executive officers;
all members of our board of directors and our executive officers as a group.

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities and include common shares that can be acquired within 60 days of February 29, 2024. The percentage ownership information shown in the table is based upon 59,580,087 common shares outstanding as of February 29, 2024.

Except as otherwise indicated, all of the shares reflected in the table are common shares and all persons listed below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. The information is not necessarily indicative of beneficial ownership for any other purpose.

142

Table of Contents

In computing the number of common shares beneficially owned by a person and the percentage ownership of that person, we deemed outstanding common shares subject to options held by that person that are immediately exercisable or exercisable within 60 days of February 29, 2024. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person. The information in the table below is based on information known to us or ascertained by us from public filings made by the shareholders.

The address of Linc AB is Birger Jarlsgatan 36, 114 29 Stockholm, Sweden.

Each of our shareholders is entitled to one vote per common share. None of the holders of our shares have different voting rights from other holders of shares. We are not aware of any arrangement that may, at a subsequent date, result in a change of control of our company.

As of February 29, 2024, we had one holder of record of our ADSs in the United States, which is CITIBANK ADR. This shareholder held in the aggregate 5.3% of the 59,580,087 common shares outstanding as of February 29, 2024. The number of record holders in the United States is not representative of the number of beneficial holders nor is it representative of where such beneficial holders are resident since many of these common shares were held by brokers or other nominees. As of December 31, 2023, assuming that all of our common shares represented by ADSs are held by residents of the United States, we estimate that approximately 15.0% of our outstanding common shares were held in the United States by approximately 34 institutional holders of record.

To our knowledge, and other than changes in percentage ownership as a result of the shares issued in connection with our initial US public offering, there has been no significant change in the percentage ownership held by the major shareholders listed above.

B.RELATED PARTY TRANSACTIONS

Other than compensation arrangements described in “Management” elsewhere in this annual report, since January 1, 2023, we have not engaged in any transactions with our executive officers, directors or holders of more than 5% of our share capital, including their affiliates, which we refer to as our related parties.

Agreements with Our Executive Officers and Directors

We have entered into employment agreements with certain of our executive officers. These agreements contain customary provisions and representations, including confidentiality, non-competition, non-solicitation and inventions assignment undertakings by the executive officers and non-executive directors. The enforceability of the non-competition provisions may be limited under applicable law.

(iv)Related Party Transactions Policy

We have adopted a related party transaction policy requiring that all related party transactions required to be disclosed by a foreign private issuer pursuant to the Exchange Act be approved by the audit committee or another independent body of our board of directors.

A.CONSOLIDATED STATEMENTS AND OTHER FINANCIAL INFORMATION

(v)Consolidated financial statements

The consolidated financial statements are included as part of this annual report, starting at page F-1.

(vi)Legal proceedings

From time to time, we may become involved in legal, governmental or arbitration proceedings or be subject to claims arising in the ordinary course of our business.

B.MEMORANDUM AND ARTICLES OF ASSOCIATION

We are a Swedish public limited company registered with the Swedish Companies Registration Office (corporate registration number 556659-9766). Below are summaries of the material provisions of our articles of association and of related material provisions of the Swedish Companies Act.

Articles of Association

Object of the Company

Our object is set forth in Section 3 of our articles of association and is to, directly or through subsidiaries, conduct research and development as well as the manufacture and sale of pharmaceuticals and medical devices, own and manage shares and other securities as well as other tangible and intangible property, as well as any other business associated therewith.

Powers of the Directors

Our board of directors shall direct our policy and shall supervise the performance of our chief executive officer and his or her actions. Our board of directors may exercise all powers that are not required under the Swedish Companies Act or under our articles of association to be exercised or taken by our shareholders.

Number of Directors

Our articles of association provide that our board of directors shall consist of three to ten members. Our board of directors currently has six members, with no deputy members.

Rights Attached to Shares

The shares shall be issued in two classes, ordinary shares and C-shares. All of the common shares have equal rights to our assets and earnings, and are entitled to one vote at the general meeting. Holders of C-shares are entitled to one tenth vote per share. At the general meeting, every shareholder may vote to the full extent of their shares held or represented, without limitation. Each share entitles the shareholder to the same preferential rights related to issues of shares, warrants and convertible bonds relative to the number of shares they own. The common shares have equal rights to dividends and any surplus capital upon liquidation, whereas the C-shares do not entitle to dividends. Upon liquidation, C-shares carry equivalent right to our assets as other shares, however not to an amount exceeding the quota value of the share. Shareholders’ rights can only be changed in accordance with the procedures set out in the Swedish Companies Act. Transfers of shares are not subject to any restrictions. There are no limitations on the rights to own securities.

146

Table of Contents

Exclusive Forum

Our articles of association provide that, unless we consent in writing to the selection of an alternative forum and without any infringement on Swedish forum provisions and without applying Chapter 7, Section 54 of the Swedish Companies Act, the United States District Court for the Southern District of New York shall be the sole and exclusive forum for resolving any complaint filed in the United States asserting a cause of action arising under the Securities Act, or the Federal Forum Provision. We recognize that the proposed Federal Forum Provision may impose additional litigation costs on shareholders in pursuing any such claims, particularly if the shareholders do not reside in or near the State of New York. Additionally, proposed Federal Forum Provision may limit our shareholders’ ability to bring a claim in a US judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage the filing of lawsuits against us and our directors, officers and employees, even though an action, if successful, might benefit our shareholders.

Preemptive Rights

Under the Swedish Companies Act, shareholders of any class of shares will generally have a preemptive right to subscribe for shares or warrants issued of any class in proportion to their shareholdings. Shareholders will have preferential rights to subscribe for new shares in proportion to the number of shares they own. If an offering is not fully subscribed for based on subscription rights, shares may be allocated to subscribers without subscription rights. The preemptive right to subscribe does not apply in respect of shares issued for consideration by payment in kind or of shares issued pursuant to convertible debentures or warrants previously issued by the company without preemptive rights for the shareholders.

The preemptive right to subscribe for new shares may be set aside. A share issue with deviation from the shareholders’ preemptive rights may be resolved either by the shareholders at a general meeting, or by the board of directors if the board resolution is preceded by an authorization therefor from the general meeting. A resolution to issue shares with deviation from the shareholders’ preemptive rights and a resolution to authorize the board of directors to do the same must be passed by two-thirds or, in certain situations, nine-tenths of both the votes cast and the shares represented at the general meeting resolving on the share issue or the authorization of the board of directors.

Voting at Shareholder Meetings

Under the Swedish Companies Act, shareholders entered into the shareholders’ register as of the record date are entitled to vote at a general meeting (in person or by appointing a proxyholder). In accordance with our articles of association, shareholders must give notice of their intention to attend the general meeting no later than the date specified in the notice. Shareholders who have their shares registered through a nominee and wish to exercise their voting rights at a general meeting must request to be temporary registered as a shareholder and entered into the shareholders’ register four business days prior to the date of the general meeting. The board of directors has the right before a shareholders’ meeting to decide that shareholders shall be able to exercise their right to vote by post before the shareholders’ meeting. The rights described herein do not apply to holders of ADSs. See “Item 12.D.—American Depositary Shares.”

Shareholder Meetings

The general meeting of shareholders is our highest decision-making body and serves as an opportunity for our shareholders to make decisions regarding our affairs. Shareholders who are registered in the share register held by Euroclear Sweden AB six business days before the meeting and have notified us no later than the date specified in the notice described below have the right to participate at our general meetings, either in person or by a representative. All shareholders have the same participation and voting rights at general meetings. At the annual general meeting, inter alia, members of the board of directors are elected, the principles for the appointment of the nomination committee are established, and a vote is held on whether each individual board member and the chief executive officer will be discharged from any potential liabilities for the previous fiscal year. Auditors are elected as well. Decisions are made concerning adoption of annual reports, allocation of earnings, fees for the board of directors and the auditors, guidelines for executive remuneration, the remuneration report and other essential matters that require a decision by the meeting. Most decisions require a simple majority, but the Swedish Companies Act dictates other thresholds in certain instances. See “—Differences in Corporate Law—Shareholder Vote on Certain Transactions.”

147

Table of Contents

Shareholders have the right to ask questions to our board of directors and managers at general meetings which pertain to the business of the company and also have an issue brought forward at the general meeting. In order for us to include the issue in the notice of the annual general meeting, a request of issue discussion must be received by us normally seven weeks before the meeting. Any request for the discussion of an issue at the annual general meeting shall be made to the board of directors and any request within the nomination committee’s competence shall be made to the nomination committee. The board shall convene an extraordinary general meeting if shareholders who together represent at least 10% of all shares in the company so demand in writing to discuss or resolve on a specific issue.

The arrangements for the calling of general meetings are described below in “—Differences in Corporate Law—Annual General Meeting” and “—Differences in Corporate Law—Special Meeting.”

Notices

The Swedish Companies Act requirements for notice are described below in “—Differences in Corporate Law—Notices.”

Subject to our articles of association and Nasdaq Stockholm’s Rulebook for Issuers, we must publish the full notice of a general meeting by way of press release, on our website and in the Swedish Official Gazette, and must also publish in the Svenska Dagbladet, a daily Swedish newspaper, that such notice has been published. The notice of the annual general meeting will be published six to four weeks before the meeting. The notice must include an agenda listing each item that shall be voted upon at the meeting. The notice of any extraordinary general meetings will be published six to three weeks before the meeting. Pursuant to the Swedish Code of Corporate Governance, which does not carry the force of law but is considered ideal corporate governance practice for Swedish companies whose shares trade on a regulated market, we shall, as soon as the time and venue for the annual general meeting have been decided, and no later than in conjunction with the third quarter report, publish such information on our website.

Record Date

Under the Swedish Companies Act, in order for a shareholder to participate in a shareholders’ meeting, the shareholder must have its shares registered in its own name in the share register four business days. In accordance with section 8 of our articles of association, shareholders must give notice of their intention to attend the shareholders’ meeting no later than the date specified in the notice.

Amendments to the Articles of Associations

Under the Swedish Companies Act, an amendment of our articles of association requires a resolution passed at a shareholders’ meeting. The number of votes required for a valid resolution depends on the type of amendment, however, any amendment must be approved by not less than two-thirds of the votes cast and represented at the meeting. The board of directors is not allowed to make amendments to the articles of association absent shareholder approval.

Provisions Restricting Change in Control of Our Company

Neither our articles of association nor the Swedish Companies Act contains any restrictions on change of control.

Differences in Corporate Law

The applicable provisions of the Swedish Companies Act differ from laws applicable to US corporations and their shareholders. Set forth below is a summary of certain differences between the provisions of, inter alia, the Swedish Companies Act applicable to us and the Delaware General Corporation Law relating to shareholders’ rights and protections. We are not subject to Delaware law but are presenting this description for comparative purposes. This summary is not intended to be a complete discussion of the respective rights and it is qualified in its entirety by reference to Delaware law and Swedish law.

Number of Directors

   

Sweden. Under the Swedish Companies Act, a public company shall have a board of directors consisting of at least three directors. More than half of the directors shall be resident within the EEA (unless otherwise approved by the Swedish Companies Registration Office). The actual number of board members shall be determined by a shareholders’ meeting, within the limits set out in the company’s articles of association. Under the Swedish Code of Corporate Governance, only one director may also be a senior executive of the relevant company or a subsidiary. The Swedish Code of Corporate Governance includes certain independence requirements for the directors, and requires a majority of the directors to be independent of the company and at least two directors to also be independent of major shareholders.

Delaware. Under the Delaware General Corporation Law, a corporation must have at least one director and the number of directors shall be fixed by or in the manner provided in the bylaws. The Delaware General Corporation Law does not address director independence, though Delaware courts have provided general guidance as to determining independence, including that the determination must be both an objective and a subjective assessment.

Removal of Directors

Sweden. Under the Swedish Companies Act, directors appointed at a general meeting may be removed by a resolution adopted at a general meeting, upon the affirmative vote of a simple majority of the votes cast.

Delaware. Under the Delaware General Corporation Law, unless otherwise provided in the certificate of incorporation, directors may be removed from office, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors, except (a) unless the certificate of incorporation provides otherwise, in the case of a corporation whose board of directors is classified, shareholders may effect such removal only for cause, or (b) in the case of a corporation having cumulative voting, if less than the entire board of directors is to be removed, no director may be removed without cause if the votes cast against his removal would be sufficient to elect him if then cumulatively voted at an election of the entire board of directors, or, if there are classes of directors, at an election of the class of directors of which he is a part.

149

Table of Contents

Vacancies on the Board of Directors

Sweden. Under the Swedish Companies Act, if a director’s tenure should terminate prematurely, the election of a new director may be deferred until the time of the next annual general meeting, providing there are enough remaining directors to constitute a quorum.

Delaware. Under the Delaware General Corporation Law, vacancies on a corporation’s board of directors, including those caused by an increase in the number of directors, may be filled by a majority of the remaining directors unless (a) otherwise provided in the certificate of incorporation or by-laws of the corporation or (b) the certificate of incorporation directs that a particular class of stock is to elect such director, in which case a majority of the other directors elected by such class, or a sole remaining director elected by such class, will fill such vacancy.

Annual General Meeting

Sweden. Under the Swedish Companies Act, within six months of the end of each fiscal year, the shareholders shall hold an annual general meeting at which the board of directors shall present the annual report and auditor’s report and, for a parent company which is obliged to prepare group accounts, the group accounts and the auditor’s report for the group. Shareholder meetings shall be held in the city stated in the articles of association. The minutes of a shareholders’ meeting must be made available on the company’s website no later than two weeks after the meeting.

Delaware. Under the Delaware General Corporation Law, the annual meeting of stockholders shall be held at such place, on such date and at such time as may be designated from time to time by the board of directors or as provided in the certificate of incorporation or by the bylaws. If a company fails to hold an annual meeting or fails to take action by written consent to elect directors in lieu of an annual meeting for a period of 30 days after the date designated for the annual meeting, or if no date was designated, 13 months after either the last annual meeting or the last action by written consent to elect directors in lieu of an annual meeting, whichever is later, the Delaware Court of Chancery may summarily order a meeting to be held upon the application of any stockholder or director. The Delaware General Corporation Law does not require minutes of stockholders’ meetings to be made public.

Special Meeting

Sweden. Under the Swedish Companies Act, the board of directors shall convene an extraordinary general meeting if a shareholder minority representing at least ten per cent of the company’s shares or the auditor of the company so demands, and the board of directors may convene an extraordinary general meeting whenever it believes reason exists to hold an extraordinary general meeting prior to the next annual general meeting.

Delaware. Under the Delaware General Corporation Law, special meetings of the stockholders may be called by the board of directors or by such person or persons as may be authorized by the certificate of incorporation or by the bylaws.

Notices

Sweden. Under the Swedish Companies Act, a shareholders’ meeting must be preceded by a notice. The notice of the annual general meeting of shareholders must be issued no sooner than six weeks and no later than four weeks before the date of an annual general meeting. In general, notice of other extraordinary general meetings must be issued no sooner than six weeks and no later than three weeks before the meeting. Publicly listed companies must always notify shareholders of a general meeting by advertisement in a Swedish newspaper, the Swedish Official Gazette, by press release, and on the company’s website.

Delaware. Under the Delaware General Corporation Law, unless otherwise provided in the certificate of incorporation or bylaws, written notice of any meeting of the stockholders must be given to each stockholder entitled to vote at the meeting not less than ten nor more than 60 days before the date of the meeting and shall specify the place, date, hour, and purpose or purposes of the meeting.

150

Table of Contents

Preemptive Rights

Sweden. Under the Swedish Companies Act, shareholders of any class of shares have a preemptive right (Sw. företrädesrätt) to subscribe for shares issued of any class in proportion to their shareholdings. The preemptive right to subscribe does not apply in respect of shares issued for consideration other than cash or of shares issued pursuant to convertible debentures or warrants previously issued by the company without preemptive rights for the shareholders. The preemptive right to subscribe for new shares may also be set aside by a resolution passed by two thirds or, in certain situations, nine-tenths of the votes cast, and shares represented at the shareholders’ meeting resolving upon the issue.

Delaware. Under the Delaware General Corporation Law, unless otherwise provided in a corporation’s certificate of incorporation, a stockholder does not, by operation of law, possess preemptive rights to subscribe to additional issuances of the corporation’s stock.

Shareholder Vote on Certain Transactions

Sweden. In matters which do not relate to elections and are not otherwise governed by the Swedish Companies Act or the articles of association, resolutions shall be adopted at the general meeting by a simple majority of the votes cast. In the event of a tied vote, the chairman shall have the casting vote. For matters concerning securities of the company, such as new share issuances, and other transactions such as private placements, mergers, and a change from a public to a private company (or vice-versa), the articles of association may only prescribe thresholds which are higher than those provided in the Swedish Companies Act.

Delaware. Generally, under Delaware law, unless the certificate of incorporation provides for the vote of a larger portion of the stock, completion of a merger, consolidation, sale, lease or exchange of all or substantially all of a corporation’s assets or dissolution requires: (i) the approval of the board of directors; and (ii) approval by the vote of the holders of a majority of the outstanding stock or, if the certificate of incorporation provides for more or less than one vote per share, a majority of the votes of the outstanding stock of a corporation entitled to vote on the matter.

Unless otherwise prescribed in the articles of association, the person who receives the most votes in an election shall be deemed elected. In general, a resolution involving the alteration of the articles of association shall be valid only when supported by shareholders holding not less than two-thirds of both the votes cast and the shares represented at the general meeting. The Swedish Companies Act lays out numerous exceptions for which a higher threshold applies, including restrictions on certain rights of shareholders, limits on the number of shares shareholders may vote at the general meeting, directed share issues to directors, employees and other closely related parties, and changes in the legal relationship between shares.

C.MATERIAL CONTRACTS

We have not entered into any material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the Company,” “Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions,” or elsewhere in this annual report on Form 20-F.

D.EXCHANGE CONTROLS

There is no Swedish legislation affecting the import or export of capital or the remittance of dividends, interest or other payments to non-resident holders of our securities, except that, subject to the provisions in any tax treaty, dividends are subject to withholding tax.

E.TAXATION

General

The taxation discussion set forth below does not purport to be a complete analysis or listing of all potential tax effects relevant to the acquisition, ownership, or disposition of our common shares or ADSs. The statements of United States and Swedish tax laws set forth below are based on the laws in force as of the date of this report and may be subject to any changes in United States or Swedish law, and in any double taxation convention or treaty between the United States and Sweden, occurring after that date, which changes may then have retroactive effect.

Specific tax provisions may apply for certain categories of taxpayers. Your tax treatment if you are a holder of our common shares or ADSs depends in part on your particular situation. If you are a holder of our common shares or ADSs, you should therefore consult a tax advisor as to the tax consequences relating to your particular circumstances resulting from the ownership of our common shares or ADSs.

Certain United States Federal Income Tax Consequences

The following is a description of certain material US federal income tax considerations for US Holders (defined below) with respect to their ownership and disposition of our common shares or ADSs. It is not a comprehensive description of all tax considerations that may be relevant to a particular person’s decision to acquire common shares or ADSs. This discussion applies only to a US Holder that holds our common shares or ADSs as a capital asset for tax purposes (generally, property held for investment). In addition, it does not describe all of the tax consequences that may be relevant in light of a US Holder’s particular circumstances, including state and local tax consequences, estate tax consequences, alternative minimum tax consequences, the potential application of the Medicare contribution tax, and tax consequences applicable to US Holders subject to special rules, such as:

banks, insurance companies, and certain other financial institutions;
US expatriates and certain former citizens or long-term residents of the United States;
dealers or traders in securities who use a mark-to-market method of tax accounting;
persons required for US federal income tax purposes to conform the timing of income accruals to their financial statements under Section 451(b) of the Code;
persons holding common shares or ADSs as part of a hedging transaction, “straddle,” wash sale, conversion transaction or integrated transaction or persons entering into a constructive sale with respect to common shares or ADSs;
persons whose “functional currency” for US federal income tax purposes is not the US dollar;
brokers, dealers or traders in securities, commodities, or currencies;
tax-exempt entities or government organizations;
S corporations, partnerships, or other entities or arrangements classified as partnerships for US federal income tax purposes;
regulated investment companies or real estate investment trusts;
persons who acquired our common shares or ADSs pursuant to the exercise of any employee stock option or otherwise as compensation;
persons holding our common shares or ADSs in connection with a trade or business, permanent establishment, or fixed base outside the United States; and

152

Table of Contents

persons who own (directly, constructively or through attribution) 10% or more (by vote or value) of our outstanding common shares or ADS.

If an entity that is classified as a partnership for US federal income tax purposes holds common shares or ADSs, the US federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding common shares or ADSs and partners in such partnerships are encouraged to consult their tax advisors as to the particular US federal income tax consequences of holding and disposing of common shares or ADSs.

The discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury Regulations, and the Convention Between the Government of the United States and the Government of Sweden for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income, signed on September 1, 1994 or the US-Sweden Tax Treaty, all as of the date hereof, changes to any of which may affect the tax consequences described herein—possibly with retroactive effect.

A “US Holder” is a holder who, for US federal income tax purposes, is a beneficial owner of common shares or ADSs and is:

(i)an individual who is a citizen or resident of the United States;
(ii)a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia;
(iii)an estate the income of which is subject to US federal income taxation regardless of its source; or
(iv)a trust if (1) a US court is able to exercise primary supervision over the administration of the trust and one or more US persons have authority to control all substantial decisions of the trust or (2) the trust has a valid election to be treated as a US person under applicable US Treasury Regulations.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. Accordingly, a holder of an ADS should be treated for US federal income tax purposes as holding the common shares represented by the ADS.

PERSONS CONSIDERING AN INVESTMENT IN COMMON SHARES OR ADSs SHOULD CONSULT THEIR TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES APPLICABLE TO THEM RELATING TO THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE COMMON SHARES OR ADSs, INCLUDING THE APPLICABILITY OF US FEDERAL, STATE AND LOCAL TAX LAWS.

PFIC Rules

A non-US corporation will be classified as a PFIC for any taxable year in which, after applying certain look-through rules, either:

at least 75% of its gross income is passive income (determined under applicable Treasury Regulations); or
at least 50% of its average percentage of gross assets (determined under applicable Treasury Regulations) is attributable to assets that produce passive income or are held for the production of passive income.

If a non-US corporation owns directly or indirectly at least 25% by value of the stock of another entity treated as a corporation or partnership for US federal income tax purposes (or, in the case of a partnership, the non-US corporation satisfies active partner tests with respect to the partnership), the non-US corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of such entity and as receiving directly its proportionate share of the other entity’s income.

153

Table of Contents

Based on our analysis of our income, assets, activities and market capitalization for our taxable year ended December 31, 2023, we do not believe that we were a PFIC for our taxable year ended December 31, 2023. Because PFIC status is a fact specific determination that generally cannot be made until the close of the taxable year in question, the calculation of the value of our non-cash assets may be based in part on the value of our common shares or ADSs, the value of which may fluctuate considerably, and we hold a substantial amount of cash and cash equivalents, our PFIC status may change from year to year, it is difficult to predict whether we will be a PFIC for the current taxable year or any future year, and no assurance can be given that we will not be a PFIC for our current taxable year or any future year. Therefore, we have not yet made any determination as to our expected PFIC status for the current year. Even if we determine that we are not a PFIC after the close of a taxable year, there can be no assurance that the IRS will agree with our conclusion. Furthermore, because there are uncertainties in the application of the relevant rules, it is possible that the IRS may challenge our classification of certain income and assets as non-passive or our valuation of our tangible and intangible assets, each of which may result in us being treated as a PFIC. Our United States counsel expresses no opinion with respect to our PFIC status for any prior, the current, or any future taxable year.

If we are classified as a PFIC in any year with respect to which a US Holder owns the common shares or ADSs, we will continue to be treated as a PFIC with respect to such US Holder in all succeeding years during which the US Holder owns the common shares or ADSs, regardless of whether we continue to meet the tests described above unless we cease to be a PFIC and the US Holder has made a “deemed sale” election under the PFIC rules. If the “deemed sale” election is made, the US Holder will be deemed to have sold the common shares or ADSs the US Holder holds at their fair market value and any gain from such deemed sale would be subject to the rules described below. After the deemed sale election, so long as we do not become a PFIC in a subsequent taxable year, the US Holder’s common shares or ADSs with respect to which such election was made will not be treated as shares in a PFIC and the US Holder will not be subject to the rules described below with respect to any “excess distribution” the US Holder receives from us or any gain from an actual sale or other disposition of the common shares or ADSs.

For each taxable year we are treated as a PFIC with respect to US Holders, US Holders will be subject to special tax rules with respect to any “excess distribution” such US Holder receives and any gain such US Holder recognizes from a sale or other disposition (including, under certain circumstances, a pledge) of common shares or ADSs, unless (i) such US Holder makes a “qualified electing fund” election, or QEF Election, with respect to all taxable years during such US Holder’s holding period in which we are a PFIC or (ii) our common shares or ADSs constitute “marketable” securities, and such US Holder makes a mark-to-market election as discussed below. Distributions a US Holder receives in a taxable year that are greater than 125% of the average annual distributions a US Holder received during the shorter of the three preceding taxable years or the US Holder’s holding period for the common shares or ADSs will be treated as an excess distribution. Under these special tax rules:

the excess distribution or gain will be allocated ratably over a US Holder’s holding period for the common shares or ADSs;
the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we became a PFIC, will be treated as ordinary income; and
the amount allocated to each other year will be subject to the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the common shares or ADSs cannot be treated as capital, even if a US Holder holds the common shares or ADSs as capital assets. In addition, if we are a PFIC, a US Holder will generally be subject to similar rules with respect to distributions we receive from, and our dispositions of the stock of, any of our direct or indirect subsidiaries that also are PFICs, as if such distributions were indirectly received by, and/or dispositions were indirectly carried out by, such US Holder. US Holders should consult their tax advisors regarding the application of the PFIC rules to our subsidiaries.

If a US Holder makes an effective QEF Election, the US Holder will be required to include in gross income each year, whether or not we make distributions, as capital gains, such US Holder’s pro rata share of our net capital gains and, as ordinary income, such US Holder’s pro rata share of our earnings in excess of our net capital gains. However, a US Holder can only make a qualified electing fund election with respect to common shares in a PFIC if such company agrees to furnish such US Holder with certain tax information annually. We do not currently intend to provide US Holders with the information necessary for US Holders to make a QEF Election. Therefore, you should assume that you will not receive such information from us and would therefore be unable to make a QEF Election with respect to any of our common shares or ADSs were we to be or become a PFIC.

154

Table of Contents

US Holders can avoid the interest charge on excess distributions or gain relating to the common shares or ADSs by making a mark-to-market election with respect to the common shares or ADSs, provided that the common shares or ADSs are “marketable.” Common shares or ADSs will be marketable if they are “regularly traded” on certain US stock exchanges or on a foreign stock exchange that meets certain conditions. For these purposes, the common shares or ADSs (respectively) will be considered regularly traded during any calendar year during which they are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Any trades that have as their principal purpose meeting this requirement will be disregarded. It should be noted that only the ADSs and not our common shares are listed on the Nasdaq Global Select Market. The Nasdaq Global Select Market is a qualified exchange for this purpose and, consequently, if the ADSs are regularly traded, the mark-to-market election should be available to a US Holder. Consequently, our common shares may not be marketable if Nasdaq Stockholm (where our common shares are currently listed) does not meet the applicable requirements. Each US Holder should consult its tax advisor as to the whether a mark-to-market election is available or advisable with respect to the common shares or ADSs.

A US Holder that makes a mark-to-market election must include in ordinary income for each year an amount equal to the excess, if any, of the fair market value of the common shares or ADSs at the close of the taxable year over the US Holder’s adjusted tax basis in the common shares or ADSs. An electing holder may also claim an ordinary loss deduction for the excess, if any, of the US Holder’s adjusted basis in the common shares or ADSs over the fair market value of the common shares or ADSs at the close of the taxable year, but this deduction is allowable only to the extent of any net mark-to-market gains for prior years. Gains from an actual sale or other disposition of the common shares or ADSs will be treated as ordinary income, and any losses incurred on a sale or other disposition of the shares will be treated as an ordinary loss to the extent of any net mark-to-market gains for prior years. Once made, the election cannot be revoked without the consent of the Internal Revenue Service, or the IRS, unless the common shares or ADSs cease to be marketable.

However, a mark-to-market election generally cannot be made for equity interests in any lower-tier PFICs that we own, unless shares of such lower-tier PFIC are themselves “marketable.” As a result, even if a US Holder validly makes a mark-to-market election with respect to our common shares or ADSs, the US Holder may continue to be subject to the PFIC rules (described above) with respect to its indirect interest in any of our investments that are treated as an equity interest in a PFIC for US federal income tax purposes. US Holders should consult their tax advisors to determine whether any of these elections would be available and if so, what the consequences of the alternative treatments would be in their particular circumstances. Unless otherwise provided by the US Treasury, each US shareholder of a PFIC is required to make an annual filing containing such information as the US Treasury may require. US Holders should consult their tax advisors regarding the requirements of filing such information returns under these rules.

WE STRONGLY URGE YOU TO CONSULT YOUR TAX ADVISOR REGARDING THE IMPACT OF OUR PFIC STATUS ON YOUR INVESTMENT IN THE COMMON SHARES OR ADSs AS WELL AS THE APPLICATION OF THE PFIC RULES TO YOUR INVESTMENT IN THE COMMON SHARES OR ADSs.

Taxation of Distributions

Subject to the discussion above under “PFIC rules,” distributions paid on common shares or ADSs, other than certain pro rata distributions of common shares or ADSs, will generally be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under US federal income tax principles). Because we may not calculate our earnings and profits under US federal income tax principles, we expect that distributions generally will be reported to US Holders as dividends. Non-corporate US Holders may qualify for the preferential rates of taxation with respect to dividends on our common shares or ADSs applicable to long-term capital gains (i.e., gains from the sale of capital assets held for more than one year) applicable to qualified dividend income (as discussed below) if we are a “qualified foreign corporation” and certain other requirements (discussed below) are met. A non-US corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign corporation (a) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is satisfactory for purposes of this provision and which includes an exchange of information provision, or (b) with respect to any dividend it pays on common shares or ADSs that are readily tradable on an established securities market in the United States. Our ADSs are listed on the Nasdaq Global Select Market, which is an established securities market in the United States, and we expect the ADSs to be readily tradable on the Nasdaq Global Select Market. However, there can be no assurance that the ADSs will be considered readily tradable on an established securities market in the United States. We are incorporated under the laws of Sweden, and we believe that we qualify as a resident of Sweden for purposes of, and are eligible for the benefits of, the US-Sweden Tax Treaty, although there can be no assurance in this regard. Further, the IRS has determined that the US-Sweden Tax Treaty is satisfactory for purposes of the qualified dividend rules and that it includes an exchange-of-information program. Therefore, subject to the discussion regarding the PFIC rules, such dividends will generally be expected to be “qualified dividend income” in the hands of individual US Holders, provided that a holding period requirement (more than 60 days of ownership, without protection from the risk of loss, during the 121-day period beginning 60 days before the ex-dividend date) and certain other requirements are met. However, the qualified dividend income treatment will not apply if we are treated as a PFIC with respect to the US Holder. Each US Holder is advised to consult its tax advisors regarding the availability of the reduced tax rate on dividends with regard to its particular circumstances.

The amount of any dividend will be treated as foreign-source dividend income to US Holders and will not be eligible for the dividends-received deduction generally available to US corporations under the Code. Dividends will generally be included in a US Holder’s income on the date of the US Holder’s receipt of the dividend. The amount of any dividend income paid in foreign currency will be the US dollar amount calculated by reference to the exchange rate in effect on the date of actual or constructive receipt, regardless of whether the payment is in fact converted into US dollars. If the dividend is converted into US dollars on the date of receipt, a US Holder should not be required to recognize foreign currency gain or loss in respect of the dividend income. A US Holder may have foreign currency gain or loss if the dividend is converted into US dollars after the date of receipt. Such gain or loss would generally be treated as US-source ordinary income or loss.

Subject to applicable limitations, some of which may vary depending upon your circumstances, Swedish income taxes withheld from dividend payments on shares at a rate not exceeding an applicable rate under the US-Sweden Tax Treaty will be creditable against your US federal income tax liability. Swedish income taxes withheld in excess of the applicable rate under the US-Sweden Tax Treaty will not be eligible for credit against your US federal income tax liability. The rules governing foreign tax credits are complex and US Holders should therefore consult their tax advisors regarding the effect of the receipt of dividends for foreign tax credit limitation purposes.

Sale or Other Taxable Disposition of Common Shares and ADSs

Subject to the discussion above under “PFIC rules,” gain or loss realized on the sale or other taxable disposition of common shares or ADSs will be capital gain or loss and will be long-term capital gain or loss if the US Holder held the common shares or ADSs for more than one year. The amount of the gain or loss will equal the difference between the US Holder’s tax basis in the common shares or ADSs disposed of, and the amount realized on the disposition, in each case as determined in US dollars. This gain or loss will generally be US-source gain or loss for foreign tax credit purposes. The deductibility of capital losses is subject to limitations.

156

Table of Contents

If the consideration received by a US Holder is not paid in US dollars, the amount realized will be the US dollar value of the payment received determined by reference to the spot rate of exchange on the date of the sale or other disposition. However, if the common shares or ADSs are treated as traded on an “established securities market” and you are either a cash basis taxpayer or an accrual basis taxpayer that has made a special election (which must be applied consistently from year to year and cannot be changed without the consent of the IRS), you will determine the US dollar value of the amount realized in a non-US dollar currency by translating the amount received at the spot rate of exchange on the settlement date of the sale. If you are an accrual basis taxpayer that is not eligible to or does not elect to determine the amount realized using the spot rate on the settlement date, you will recognize foreign currency gain or loss to the extent of any difference between the US dollar amount realized on the date of sale or disposition and the US dollar value of the currency received at the spot rate on the settlement date.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the United States or through certain US-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the US Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the US Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding on a duly executed IRS Form W-9 or otherwise establishes an exemption.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a US Holder will be allowed as a credit against the US Holder’s US federal income tax liability and may entitle the US Holder to a refund, provided that the required information is timely furnished to the IRS. US Holders should consult their own tax advisors regarding the backup withholding tax and information reporting rules.

Information with Respect to Foreign Financial Assets

Certain US Holders who are individuals (and, under regulations, certain entities) may be required to report information relating to the common shares or ADSs, subject to certain exceptions (including an exception for common shares or ADSs held in accounts maintained by certain US financial institutions), by filing IRS Form 8938 (Statement of Specified Foreign Financial Assets) with their federal income tax return. Such US Holders who fail to timely furnish the required information may be subject to a penalty. Additionally, if a US Holder does not file the required information, the statute of limitations with respect to tax returns of the US Holder to which the information relates may not close until three years after such information is filed. US Holders should consult their tax advisors regarding their reporting obligations with respect to their ownership and disposition of the common shares or ADSs.

Material Swedish Tax Considerations

The following is a summary of certain material Swedish tax issues for holders of common shares or ADSs that are not resident in Sweden for tax purposes. The summary is based on current legislation and is intended to provide general information only. The summary does not cover, inter alia, the special rules regarding tax-free dividends that may be applicable when investors hold common shares or ADSs that are deemed to be held for business purposes (for tax purposes), foreign companies conducting business through a permanent establishment in Sweden, or foreign companies that have been Swedish companies. Each person considering an investment in common shares or ADSs is advised to consult an independent tax advisor as to the tax consequences that could arise from the acquisition, ownership and disposition of the common shares or ADSs.

Table of Contents

Taxation of Dividends

For holders not resident in Sweden for tax purposes that receive dividends on common shares or ADSs of a Swedish limited liability company, Swedish withholding tax is normally withheld. The same withholding tax applies to certain other payments made by a Swedish limited liability company, such as payments as a result of redemption of shares and repurchase of shares through an offer directed to all shareholders or all holders of a certain class. The withholding tax rate is 30%. The tax rate is, however, generally reduced under an applicable tax treaty. For example, under the US-Sweden Tax Treaty the tax rate on dividends paid to US holders entitled to the benefits of the US-Sweden Tax Treaty should not exceed 15%. In Sweden, withholding tax deductions are normally carried out by Euroclear Sweden AB or, in respect of nominee-registered shares, by the nominee. The tax treaties Sweden has entered into generally enable the withholding tax deduction to be made in accordance with the tax rate stipulated in the treaty, provided that Euroclear Sweden AB or the nominee, as applicable, has received the required information concerning the tax residency of the investor entitled to the dividend (this applies also under the US—Sweden tax treaty). Furthermore, investors entitled to reduced tax rates under applicable tax treaties may claim a refund from the Swedish tax authorities within five calendar years following the year the dividend was distributed if the full withholding tax rate at 30% has been withheld.

Taxation of Capital Gains

Holders not resident in Sweden for tax purposes are normally not liable for capital gains taxation in Sweden upon disposals of common shares or ADSs. Holders of common shares or ADSs may, however, be subject to taxation in their state of residence.

According to a special rule, private individuals not resident in Sweden for tax purposes are, however, subject to Swedish capital gains taxation upon disposals of common shares or ADSs if they have been residents of Sweden due to a habitual abode in Sweden or a continuous stay in Sweden at any time during the calendar year of disposal or the ten calendar years preceding the year of disposal. In a number of cases though, the applicability of this rule is limited by tax treaties. For example, under the US-Sweden Tax Treaty this rule applies for ten years from the date the private individuals became non-resident of Sweden for tax purposes.

ITEM 11.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Quantitative and Qualitative Disclosures about Market Risks

Market risk is the risk that the fair value of, or future cash flows from, a financial instrument will vary due to changes in market prices. The type of market risk that primarily impacts us is foreign currency risk.

Foreign Currency Risk

Translation Exposure

We maintain our consolidated financial statements in our functional currency Swedish Kronor, which is also our functional currency. All amounts, unless otherwise stated, are rounded to the nearest thousand.

Transactions in foreign currency are translated to the functional currency at the exchange rate on the date of the transaction. Monetary assets and liabilities in foreign currency are translated to the functional currency at the exchange rate that applies on the closing date. Exchange rate differences arising on translation are recognized in net profit for the year. Foreign exchange gains and losses on operating receivables and liabilities are recognized in operating profit, while foreign exchange gains and losses on financial receivables and liabilities are recognized as financial items.

Assets and liabilities in foreign operations are translated from the functional currency of the operations to our presentation currency at the exchange rate applicable on the closing date. Income and expenses in a foreign operation are translated to SEK at the average exchange rate which corresponds to an approximation of the exchange rates prevailing on each individual transaction date. Translation differences arising in the translation of foreign operations’ functional currencies are recognized in the consolidated statements of comprehensive income.

We recorded foreign currency transaction gains/(losses) of SEK 16.6 million and SEK 7.1 million for the years ended December 31, 2023 and 2022, respectively. These foreign currency transaction gains/(losses) are included in other operating income and other operating expenses in our consolidated financial statements.

We recorded foreign exchange rate difference translation gains of SEK 1.3 million and SEK 46.6 million for the years ended December 31, 2023 and 2022, respectively. These foreign exchange rate gains/(losses) are included in financial income and financial expenses in our consolidated financial statements.

Our primary transaction exposure is in Euros and US dollars. A 10% stronger Euro against the Swedish Krona would have a negative impact on profit after tax and equity of approximately SEK 29.3 million, SEK 23.1 million and SEK 0.9 million for the years ended December 31, 2023, 2022 and 2021, respectively. A 10% stronger US dollar against the Swedish Krona would have a negative impact on profit after tax and equity of approximately pos. SEK 0.1 million, SEK 9.6 million and SEK 22.4 million for the year ended December 31, 2023, 2022 and 2021, respectively.

Interest Rate Risk

We are currently not exposed to significant interest rate risk. Our only variable interest-bearing financial assets are cash at Swedish banks. Certain European countries have recently experienced (or currently are expected to experience) negative interest rates on certain fixed-income instruments, and similar interest rate conditions may be experienced in other regions. Negative interest rates may magnify our susceptibility to interest rate risk and diminish yield and performance on our investments. Changing interest rates may have unpredictable effects on securities markets in general, directly or indirectly impacting our investments and yield.

Given the short-term nature of these investments, the sensitivity towards interest rate fluctuations is deemed not to be significant. Therefore, the effect of an increase or decrease in interest rates would only have an immaterial effect on our financial results.

As of December 31, 2023, 2022 and 2021, we had SEK 939.5 million, SEK 713.0 million and SEK 189.2 million in debt outstanding, respectively. In July 2021, we signed a loan agreement of up to the euro-equivalent of USD 75 million with Kreos Capital. The loan facility is divided into three tranches of USD 25 million each, which we drew down in September 2021, June 2022 and December 2022. The interest rate on the loan is 9% per annum with a maturity of December 2025. In December 2023, we entered into a credit agreement with Athyrium, Athyrium made available to us 92 million Euros, which we fully drew down. We used part of the proceeds from the Credit Agreement to repay in full outstanding obligations under our loan agreement with Kreos Capital. The interest rate on the loan is 9% per annum with a maturity of December 2027. The Credit Agreement contains financial covenants to maintain minimum unrestricted cash (including cash equivalents) and achieve minimum net revenue targets with respect to Nefecon. The Credit Agreement contains affirmative and negative covenants customary for a senior secured loan.

D.AMERICAN DEPOSITARY SHARES

Citibank, N.A. is the depositary bank for the American Depositary Shares, also referred to as ADSs. Each ADS represents two common shares (or a right to receive two common shares) deposited with Citibank Europe plc, as custodian for the depositary located at 1 North Wall Quay, Dublin 1, Ireland. Each ADS also represents any other securities, cash or other property which may be held by the depositary. The deposited shares, together with our other securities, cash and other property held by the depositary, are referred to as the deposited securities. The depositary’s office at which the ADSs are administered is located at 388 Greenwich Street, New York, New York 10013.

A deposit agreement among us, the depositary, ADS holders and all other persons indirectly or beneficially holding ADSs sets out ADS holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADSs. A copy of the deposit agreement is incorporated by reference as an exhibit to this annual report.

Taxes and other governmental charges the depositary or the custodian has to pay on any ADSs or shares underlying ADSs, such as stock transfer taxes, stamp duty or withholding taxes

As necessary

Any charges incurred by the depositary or its agents for servicing the deposited securities

As necessary

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may collect any of its fees by deduction from any cash distribution payable (or by selling a portion of securities or other property distributable) to ADS holders that are obligated to pay those fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

From time to time, the depositary may make payments to us to reimburse us for costs and expenses generally arising out of establishment and maintenance of the ADS program, waive fees and expenses for services provided to us by the depositary or share revenue from the fees collected from ADS holders. In performing its duties under the deposit agreement, the depositary may use brokers, dealers, foreign currency dealers or other service providers that are owned by or affiliated with the depositary and that may earn or share fees, spreads or commissions.

The depositary may convert currency itself or through any of its affiliates and, in those cases, acts as principal for its own account and not as agent, advisor, broker or fiduciary on behalf of any other person and earns revenue, including, without limitation, transaction spreads, that it will retain for its own account. The revenue is based on, among other things, the difference between the exchange rate assigned to the currency conversion made under the deposit agreement and the rate that the depositary or its affiliate receives when buying or selling foreign currency for its own account. The depositary makes no representation that the exchange rate used or obtained in any currency conversion under the deposit agreement will be the most favorable rate that could be obtained at the time or that the method by which that rate will be determined will be the most favorable to ADS holders, subject to the depositary’s obligations under the deposit agreement. The methodology used to determine exchange rates used in currency conversions is available upon request.

ITEM 15.CONTROLS AND PROCEDURES

A.DISCLOSURE CONTROLS AND PROCEDURES

Our management, with the participation of our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), has evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(b) as of December 31, 2023. While there are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures, our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives.

Based upon our evaluation as of December 31, 2023, our Chief Executive Officer and Chief Financial Officer have concluded that thus the previously identified material weaknesses regarding the Entity-level control environment, IT Processes, and Payroll have all been remediated, the disclosure controls and procedures, in accordance with Exchange Act Rule 13a-15(e), as a result of the material weaknesses in our internal control over financial reporting, as discussed below, were not effective.

To mitigate the potential impact of the material weaknesses described below, and prior to filing this annual report, we performed additional analysis and other post-closing procedures to determine that our consolidated financial statements are prepared in accordance with IFRS. Based on these procedures, management has concluded that the consolidated financial statements included in this annual report present fairly, in all material aspects, our financial position as at the end of, and the results of operations and cash flows for, the periods presented in conformity with IFRS.

B.MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act). Our internal control over financial reporting is a process designed, under the supervision of our Chief Executive Officer and Chief Financial Officer, to provide reasonable assurance regarding the reliability of financial reporting and preparation of financial statements for external reporting purposes in accordance with IFRS, as issued by the IASB.

Our internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets, provide reasonable assurance that transactions are recorded in the manner necessary to permit the preparation of financial statements in accordance with IFRS, and that receipts and expenditures are only carried out in accordance with the authorization of our management and directors, and provide reasonable assurance regarding the prevention or timely detection of any unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated financial statements. Because of its inherent limitations, internal control over financial reporting can provide only reasonable assurance and may not prevent or detect all misstatements. Further, because of changes in conditions, effectiveness of internal control over financial reporting may vary over time. Our system contains self-monitoring mechanisms, and actions are taken to correct deficiencies as they are identified.

Our management has conducted an evaluation of the effectiveness of the system of internal control over financial reporting based on the Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013. Based on this evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our internal control over financial reporting was not effective as of December 31, 2023, due to material weaknesses in our internal control over financial reporting as described below.

163

Table of Contents

A material weakness (as defined in Rule 12b-2 under the Exchange Act) is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis.

All of these material weaknesses are described below.

Financial Statement Close and Reporting Process

We did not adequately design or execute controls that address the relevant financial statement assertions over the Financial Statement Close and Reporting Process. Specifically, we did not adequately design or execute internal controls over 1) certain aspects of management review procedures; 2) certain aspects of journal entry approvals and processing; 3) review of general ledger master data changes; 4) share-based payments; and 5) income taxes.

Net Sales

We did not have effective controls in place over the recording of revenue. Specifically, we did not adequately design or execute controls over the cash receipts, master data, royalty data, and management review of gross-to-net models. Also, management did not design effective controls over the completeness and accuracy of key sources of data used in the performance of controls.

Accounts Payable, Accrued Expenses and Operating Expenses

We did not have effective internal controls in place over the procurement of goods and services and invoice processing, or the completeness, existence, and valuation of accounts payable and accrued liabilities. Specifically, we did not adequately design or execute controls over 1) certain aspects of purchase order processing as it relates to purchase order approvals, invoice processing, master data changes, authorization levels, bank disbursements; and 2) the completeness and accuracy of certain underlying key sources of data used in the performance of these controls.

Remediation Plan

We have initiated a remediation plan that includes steps to increase dedicated resources, improve reporting processes, and enhance related supporting technology. We will continue to enhance documentation of our risks-related controls and their assertions to facilitate tracking and trend analysis of internal control deficiencies to support timely remediation of the remaining material weaknesses. We will continue to leverage an outsourced team to perform independent testing of our internal controls throughout the year. We are committed to strengthen and further improve our internal control environment and implementing measures designed to help ensure that control deficiencies contributing to the remaining material weaknesses are remediated as soon as possible, as further described below. Although we intend to complete the remediation process as promptly as possible, we cannot at this time estimate how long it will take to remediate these material weaknesses, and our remediation plan may not prove to be successful. In addition, we may discover additional material weaknesses that require additional time and resources to remediate.

Our remediation process further includes, but is not limited to:

enhance variance analysis controls and procedures, as supported by a new consolidated reporting application that was implemented in Q1, 2024;
enhance balance sheet reconciliation controls and procedures, as supported by a new reconciliation application that is being implemented in Q1 and Q2, 2024;
re-design control procedures related to review of master data changes for the Chart of Accounts, customers, and vendors;
re-train control owners on the proper performance and documentation of completeness and accuracy validation procedures over the data produced by the entity (IPE) as part of their review controls;
re-train control owners on the level of precision required to complete review procedures;

164

Table of Contents

improve definition, documentation and implementation of succinct review criteria as part of certain management review controls;
enhance accrual controls and procedures through implementation of a Purchase Order module;
leverage automated reminders and defined deadlines from our internal controls library application to drive timely performance of control procedures.

We believe that the foregoing efforts should effectively remediate the material weaknesses described in this Item 15 and improve our overall control environment. Because the reliability of the internal control process requires repeatable execution and testing over multiple fiscal quarters, the successful remediation of these material weaknesses will require review and evidence of effectiveness prior to concluding that the controls are effective, and it is possible that additional remediation steps will be necessary.

As such, as we continue to evaluate and work to improve our internal control over financial reporting, our management may decide to take additional measures to address the material weaknesses or modify the remediation steps described above. Until these weaknesses are remediated, we plan to continue to perform additional analyses and other procedures to ensure that our consolidated financial statements are prepared in accordance with IFRS.

C.ATTESTATION REPORT OF THE REGISTERED PUBLIC ACCOUNTING FIRM

The effectiveness of our internal control over financial reporting as of December 31, 2023, has been audited by Ernst & Young AB, an independent public accounting firm. Their report is included beginning on page F-2.

D.CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

The previously identified material weaknesses related to the Entity-level control environment, IT Processes, and Payroll have been remediated. Except for the remediation of these material weaknesses and as described above in “—Disclosure Controls and Procedures,” there were no other changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the twelve months ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Audit Committee’s Pre-Approval Policies and Procedures

The audit committee has responsibility for, among other things, appointing, setting compensation of and overseeing the work of our independent registered public accounting firm, or external auditor. In recognition of these responsibilities, the audit committee has adopted a policy governing the pre-approval of all audit and permitted non-audit services performed by our external auditor to ensure that the provision of such services does not impair the external auditor’s independence from us and our management. Unless a type of service to be provided by our external auditor has received general pre-approval from the audit committee, it requires specific pre-approval by the audit committee. The payment for any proposed services in excess of pre-approved cost levels requires specific pre-approval by the audit committee.

Pursuant to its pre-approval policy, the audit committee may delegate its authority to pre-approve services to the chairperson of the Audit Committee. The decisions of the chairperson to grant pre-approvals must be presented to the full audit committee at its next scheduled meeting. The audit committee may not delegate its responsibilities to pre-approve services to the management.

The audit committee has considered the non-audit services provided by Ernst & Young AB as described above and believes that they are compatible with maintaining Ernst & Young AB’s independence as our external auditor. In accordance with Regulation S-X, Rule 2-01, paragraph (c)(7)(i), no fees for services were approved pursuant to any waivers of the pre-approval requirement.

ITEM 16G.CORPORATE GOVERNANCE

We qualify as a foreign private issuer. The Listing Rules of the Nasdaq Stock Market include certain accommodations in the corporate governance requirements that allow foreign private issuers to follow “home country” corporate governance practices in lieu of the otherwise applicable corporate governance standards of the Nasdaq Stock Market. While we may choose to voluntarily follow some Nasdaq corporate governance rules, we may choose to take advantage of the following limited exemptions:

exemption from filing quarterly reports on Form 10-Q containing unaudited financial and other specified information or current reports on Form 8-K upon the occurrence of specified significant events;
exemption from Section 16 rules requiring insiders to file public reports of their securities ownership and trading activities and providing for liability for insiders who profit from trades in a short period of time;
exemption from the Nasdaq requirement necessitating disclosure of any waivers of the Code of Business Conduct and Ethics for directors and executive officers;
exemption from the requirement to obtain shareholder approval for certain issuances of securities, including shareholder approval of share option plans and equity issuances;
exemption from the requirement that our audit committee have review and oversight responsibilities over all “related party transactions,” as defined in Item 7.B of Form 20-F;
exemption from the requirement that our board of directors have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and
exemption from the requirement to have independent director oversight of director nominations.

Furthermore, Nasdaq Rule 5615(a)(3) provides that a foreign private issuer may rely on home country corporate governance practices in lieu of certain of the rules in the Nasdaq Rule 5600 Series and Rule 5250(d). We intend to follow Swedish corporate governance practices in lieu of Nasdaq corporate governance requirements as follows:

We do not intend to follow Nasdaq Rule 5620(c) regarding quorum requirements applicable to meetings of shareholders. Such quorum requirements are not required under Swedish law. The Swedish Companies Act (SFS 2005:551) and our articles of association, which were approved by our shareholders on May 19, 2022 and are currently in effect, provide alternative quorum requirements that are generally applicable to meetings of shareholders.
We do not intend to follow Nasdaq Rule 5605(b)(2), which requires that independent directors regularly meet in executive sessions where only independent directors are present. Our independent directors may choose to meet in executive sessions at their discretion.
We do not intend to follow Nasdaq Rule 5605(e) regarding the composition of the nominating committee.

167

Table of Contents

Although we may rely on certain home country corporate governance practices, we must comply with Nasdaq’s Notification of Noncompliance requirement (Nasdaq Rule 5625) and the Voting Rights requirement (Nasdaq Rule 5640). Further, we must have an audit committee that satisfies Nasdaq Rule 5605(c)(3), which addresses audit committee responsibilities and authority and requires that the audit committee consist of members who meet the independence requirements of Nasdaq Rule 5605(c)(2)(A)(ii).

Because we are a foreign private issuer, our directors and executive officers are not subject to short-swing profit and insider trading reporting obligations under Section 16 of the Exchange Act. They will, however, be subject to the obligations to report changes in securities ownership under Section 13 of the Exchange Act and related SEC rules.

We intend to take all actions necessary for us to maintain compliance as a foreign private issuer under the applicable corporate governance requirements of the Sarbanes-Oxley Act, the rules adopted by the SEC and Nasdaq listing rules. Accordingly, our shareholders will not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of Nasdaq.

ITEM 16KCYBERSECURITY

Risk Management and Strategy

We have implemented and maintain various information security processes designed to identify, assess and manage material risks from cybersecurity threats to our critical systems and information (collectively, our “Information Systems and Data”).

Our Information Technology department, with support from members of our Legal and Compliance teams and our Chief Information Officer (“CIO”), helps identify and assess cybersecurity risks and prepare the Company to respond to these risks. We use various methods for monitoring and evaluating threats to our environment including, for example: using manual and automated tools to detect anomalies and attempted attacks, subscribing to reports and services that identify cybersecurity threats, evaluating our and our industry’s risk profile, analyzing reports of threats and actors, conducting scans of our environment, evaluating threats reported to us, conducting internal and external audits, conducting threat assessments for internal and external threats, and conducting vulnerability assessments, including penetration tests.

Depending on the environment and system, we implement and maintain various technical, organizational, and physical measures, processes, standards and policies designed to manage and mitigate material risks from cybersecurity threats to our Information Systems and Data. These include, in addition to others discussed in this Item 16K, system monitoring, an incident detection and response plan, a disaster recovery plan, encryption and segregation of certain data, network security controls, and measures for the physical security of our technology infrastructure. We provide an annual information security awareness training to our employees and ask them to review certain information security policies on an annual basis.

Our identification, assessment and management of material risks from cybersecurity threats are integrated into the Company’s overall risk management processes. For example, we include information on cybersecurity risk evaluations conducted by management in reports, elements of which are shared with the audit committee of our board of directors. Additionally, our Executive Committee may discuss cybersecurity risks and mitigation activities as part of its general risk management oversight. Our Group General Counsel has functional responsibility for cybersecurity and may elevate cybersecurity topics for the attention of the audit committee and board of directors.

168

Table of Contents

We use third-party service providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, including for example cybersecurity consultants, threat intelligence service providers, cybersecurity software and service providers, penetration testing firms, dark web monitoring services, forensic investigators, and professional services firms, including legal counsels.

Support elements for a variety of functions across our business are performed by third parties, such as distributors, contract manufacturing organizations, contract research organizations, application providers, and supply chain resources. We consider cyber risks in evaluating third parties and services, and our vendor management processes are tailored to our assessment of a particular vendor’s risk profile and criticality to our operations. Those processes may include, for example, some combination of the following: performing a risk assessment or issuing a security questionnaire, reviewing written security programs, performing certain vulnerability scans, conducting security assessment calls with the vendor’s security personnel, performing audits on the vendor’s compliance with our security requirements, or imposing contractual obligations relating to information security. Depending on the nature of the services provided, the sensitivity of the Information Systems and Data at issue, and the identity of the provider, our vendor management process may involve different levels of assessment designed to help identify and manage cybersecurity risks associated with a provider.

We have not identified risks from any known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected us, including our operations, business strategy, results of operations, or financial condition. For a description of the risks from cybersecurity threats that may be reasonably likely to materially affect the Company and how they may do so, see our risk factors under Item 3D. Risk Factors in this Annual Report, including those described in “Risks Related to Our Employee Matters, Managing Our Growth and Other Risks Relating to Our Operations.”

Governance

Our board of directors considers the Company’s cybersecurity risk as part of its general oversight function and is responsible for overseeing the Executive Committee’s implementation and enforcement of our cybersecurity risk management processes.

Our cybersecurity risk assessment and management processes are implemented and maintained by a management team comprised of our CIO, Group General Counsel and CFO who all report to our CEO. This management team is responsible for hiring appropriate personnel, managing spending relating to cybersecurity, providing information on cybersecurity risks, preparing for cybersecurity incidents, reviewing security assessments, approving cybersecurity processes and resources, and managing our response to significant cybersecurity incidents. The management team stays informed about and monitors efforts to prevent, detection, mitigate and remediate cybersecurity incidents through various means, which may include briefings with operational cybersecurity team members, outside threat intelligence sources, and from tooling described above that is deployed in our IT environment.

Individuals responsible for cybersecurity at an operational level within the Company have a minimum of 15 years’ experience in the field of information technology. We also have a Cyber Incident Response Team that includes the CIO, CEO, Group General Counsel, CFO, Head of HR and IT Compliance Manager. This group may be expanded as needed to include representatives from our Legal and Corporate Communications teams as well as our Executive Committee, which is responsible for communicating with the audit committee or full board of directors as needed.

The audit committee receives regular reports from the CIO concerning the Company’s significant cybersecurity threats and risks and the processes the Company has implemented to address them, as well as cybersecurity incidents deemed significant by the management team. The audit committee also has access to various reports, summaries or presentations related to cybersecurity threats, risk and mitigation.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Calliditas Therapeutics AB

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Calliditas Therapeutics AB (the Company) as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022 and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated April 24, 2024 expressed an adverse opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Estimate of variable consideration for revenue recognition

Description of the matter

    

As is stated in Note 3 of the consolidated financial statements, for the year ended December 31, 2023, the Company’s revenues from product sales were SEK 1,087,418 thousands. As more fully described in Notes 2 and 3, revenue from the sale of goods is calculated net of actual and estimated rebates to government payers, among other deductions. The Company’s determination of variable consideration at December 31, 2023, requires management to make assumptions about amounts of rebates that will be payable by the Company, as a result of the sale of products for which control has transferred.

Auditing management’s estimate of variable consideration was complex, because the calculation involves significant management judgement to determine the rebates owed to government payers.

How We Addressed the Matter in Our Audit

To test the estimate of variable consideration, our audit procedures included, among others, performing analytical procedures to assess the historical accuracy of management’s estimates, by comparing previous estimates of payor rebates to the amount of actual payments in subsequent periods. Where available, we tested management’s estimate as of December 31, 2023, by comparison to actual invoices received subsequently. We also tested the completeness and accuracy of dispensing data and inputs used by the Company in its determination of the estimated payor mix, by agreeing it to third-party data.

We involved professionals with government pricing subject matter experience, to assist in evaluating management’s methodology and calculations used to measure rebates owed to government payors.

Impairment assessment of intangible assets

Description of the matter

Intangible assets amount to SEK 430,754 thousands as of December 31, 2023. As explained in Note 2 and Note 15 of the consolidated financial statements, the Company performs an impairment assessment of intangible assets not yet available for use, on an annual basis or when there is an indication that an asset may be impaired. The Company’s impairment assessment of intangible assets, involves the comparison of the recoverable amount of each asset or cash generating unit to their carrying values.

The recoverable amount of intangible assets is estimated based on a probability-adjusted cash flow model, where the amount is determined by estimating the expected future cash flows and present value adjustments, including the probability of reaching the market. Changes in assumptions used by management could have a significant impact on the recoverable amount.

The audit of the impairment assessment of intangible assets was complex, due to the significant judgments made by management to estimate the recoverable amount, including assumptions related to the timing of potential commercialization, the market size, the probability of reaching the market and the discount rate used.

How We Addressed the Matter in Our Audit

We performed audit procedures related to the impairment assessment of intangible assets, which included, among others, testing the completeness and accuracy of inputs utilized by management in the assumptions, including the timing of potential commercialization, expected market size and the probability of the products reaching the market. In doing so, we compared these inputs to third-party statistical data for the clinical indications targeted and to other development projects within the industry.

With the assistance of our valuation specialists, we evaluated the discounted cash flow methodology and assessed the discounts rates used by management, by comparing to underlying source information, testing the mathematical accuracy of the calculations and preparing an independent range of discount rates based on market and peer company observable data and comparing to that used by management.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Calliditas Therapeutics AB

Opinion on Internal Control Over Financial Reporting

We have audited Calliditas Therapeutics AB’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weaknesses described below on the achievement of the objectives of the control criteria, Calliditas Therapeutics AB (the Company) has not maintained effective internal control over financial reporting as of December 31, 2023, based on the COSO criteria.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment. Management has identified material weaknesses related to inadequately designed controls and control operations over the financial statement close and reporting process, ineffective controls over the recording of revenue, and ineffective controls over the procurement of goods and services, invoices processing, and the completeness, existence, and valuation of accounts payable and accrued liabilities.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of financial position of the Company as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes. These material weaknesses were considered in determining the nature, timing and extent of audit tests applied in our audit of the 2023 consolidated financial statements, and this report does not affect our report dated April 24, 2024, which expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

(SEK in thousands, except per share amounts or as otherwise indicated)

Description of Business

Calliditas Therapeutics AB (publ) (“Calliditas” or the “Parent Company”), with corporate registration number 556659-9766, and its subsidiaries (collectively, the “Group”) conduct development and commercial activities in pharmaceuticals.

These consolidated financial statements encompass the Group, domiciled in Stockholm, Sweden, and its subsidiaries for the year ended December 31, 2023, 2022 and 2021, respectively. The Group has chosen to, in addition to periods such as required by IFRS, present a consolidated income statement, statement of comprehensive income, consolidated statement of cash flows and consolidated statement of changes in equity with an additional comparison period.

Calliditas is a commercial stage biopharma company focused on identifying, developing and commercializing novel treatments in orphan indications, with an initial focus on renal and hepatic diseases with significant unmet medical needs. The registered address of the corporate headquarters is Kungsbron 1, D5, Stockholm, Sweden.

Calliditas was founded as a public limited liability company under the laws of Sweden on February 20, 2004 under the name Pharmalink AB and registered with the Swedish Companies Registration Office on April 15, 2004. As of December 31, 2023, Calliditas is the Parent Company of four subsidiaries located in Sweden, France and in the United States. The Swedish subsidiary is Nefecon AB which is conducting no operating activities. The subsidiaries in the United States are Calliditas Therapeutics US Inc and Calliditas NA Enterprises Inc, who are conducting commercialization activates in the United States, respectively. The French subsidiary is Calliditas Therapeutics France SAS located in France which is conducting preclinical activities.

The Board of Directors (the “Board”) approved, and authorized for issuance, these consolidated financial statements on April 24, 2024.

Note 1 Material Accounting Policies

Basis for Preparation

These consolidated financial statements have been prepared in accordance with the IFRS (R) Accounting Standards published by the International Accounting Standards Board (IASB). In addition, the consolidated financial statements comply with the recommendation of The Swedish Corporate Reporting Board RFR 1, Supplementary Accounting Regulations for Groups.

Material accounting policies

The Group provides disclosures of material accounting policies and accounting policy is material if the underlying transaction is material and information in the accounting policy is material to understand the transaction, e.g. if the Group has made a policy choice or if the accounting policy is company specific. When the Group applies an accounting policy as described in the applicable IFRS standard, the Group does not provide any disclosure of the applied accounting policy. In addition to material accounting policies described in this note, the Group has decided to present material accounting policies within the corresponding note that the policy relates to.

Primary financial statements

The group has elected to present in addition to minimum periods required under IFRS, a consolidated statement of income, consolidated statement of comprehensive income, consolidated statement of cash flows, and consolidated statement of changes in equity, for an additional comparative period. The Group has decided to present the consolidated statement of income based on function of expense.

F-11

Table of Contents

Basis for Valuation and Current versus Non-Current Classification

The Group presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset is current when it is expected to be realized within twelve months after the reporting period. All other assets are classified as non-current. A liability is current when it is due to be settled within twelve months after the reporting period. The Group classifies all other liabilities as non-current.

Functional Currency and Reporting Currency

The Parent Company’s functional currency is Swedish Kronor (SEK), which is also the presentation currency of the Group. This means that the financial statements are presented in Swedish kronor (SEK) and all amounts, unless otherwise stated, are rounded to the nearest thousand (SEK 000s).

Foreign exchange gains and losses as a result of transactions in foreign currency relating to operating receivables and liabilities are recognized net in operating profit as Other operating income or Other operating expenses, while foreign exchange gains and losses on financial receivables and liabilities are recognized net as financial items.

Cost of Sales

Cost of sales includes the cost of inventory sold, labor costs, manufacturing overhead expenses and reserves for expected scrap, as well as shipping and freight costs. Cost of sales also includes royalty costs related to in-license agreements.

Research and Development

Research and development expenses consist primarily of costs incurred for the Group’s development activities, including the development of the Group’s product candidates. The Group expenses research and development costs as incurred. The Group recognizes external development costs based on an evaluation of the progress to completion of specific tasks using information provided by Calliditas’ service providers. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in the consolidated financial statements as a prepaid expense or accrued expense. Research and development tax credits are recognized in Sweden and in France. In Sweden tax credits are recognized on social security costs and in France tax credits are recognized on accredited suppliers. These research and development tax credits are recognized as an offset to research and development expenses in the consolidated statements of income.

Marketing and Selling Expenses

Marketing and selling expenses consist of salaries and other related costs for personnel in the Group and market access, commercialization and business development.

Administrative Expenses

Administrative expenses consist of salaries and other related costs for personnel in the Group, finance, corporate and administrative functions. Administrative expenses also include professional fees for legal, patent, accounting, auditing, tax and consulting services, related travel expenses and facility-related expenses, which include allocated expenses for rent and maintenance of facilities and other operating costs. Acquisition-related costs are included in administrative expenses in the consolidated statements of income and are expensed as the services are performed.

New and Amended Standards and Interpretations

Updated standards and interpretations from IASB and IFRIC interpretations that came into effect for the year ended December 31, 2023 have had no material impact on the Group. The Group has not early adopted any standards, interpretations or amendments that have been issued but are not yet effective.

Future Standards and New Interpretations

Other future or altered standards or interpretations that the IASB has published are not expected to have any significant impact on the financial statements for the Group.

Cash Flow

The consolidated statement of cash flows is prepared in accordance with the indirect method.

Note 2 Significant Accounting Judgements, Estimates and Assumptions

The preparation of the Group’s consolidated financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions that affect the recorded amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods.

Judgements, estimates and assumptions are evaluated on an ongoing basis. Changes in judgements, estimates and assumptions are recognized in the period the change has occurred if the change only affects that period, and future period if the change affects both the current period and future periods.

Significant accounting judgements, estimates and assumptions are disclosed in detail in the corresponding note to which the judgement, estimate and assumption relate. Significant accounting judgements, estimates and assumptions relates to:

Revenue recognition - note 3,
Loss carryforwards - note 13,
Intangible assets - note 15, and
Expected credit losses - note 20.

A summarized description of each significant accounting judgment, estimate and assumption is presented below. For additional details of the significant accounting judgments, estimates and assumptions refer to the notes referenced above.

Revenue Recognition

Outlicensing of Product

Revenue for the outlicensing of Nefecon is recognized at the point in time when control of the intellectual property is transferred, while revenue for the provision of certain regulatory services is reported over time as the services are performed. The revenue allocated to the performance obligation for outlicensing is based on the residual approach and the allocation of revenue to the performance obligation for regulatory services is based on the expected costs to provide the service, with the addition of a profit margin based on comparable companies. The identification of and allocation of the transaction price between these performance obligations hence has a significant impact on the Group's revenue recognition, as the revenue recognition patterns differ between the performance obligations.

The revenue contracts also contain variable remuneration in the form of regulatory and commercial milestones. Variable remuneration is initially considered constrained, as there is significant uncertainty as to whether the associated milestones will occur. Compensation attributable to sales-based milestones or royalties is not recognized until the sale that results in the right to the royalties has occurred. Determining whether the criteria for recognition of the variable remuneration has been met hence has significant effects on revenue recognition and requires significant judgment by Management.

Gross to Net Accounting

There are various sales deductions and rebates relating to product sales in the United States that are deducted from the gross sales as part of the revenue recognition process. As the actual sales deductions are not known at the point of sale, estimates are made in determining the initial deduction of rebates, and are then subject to true-up as actual data is obtained.

Intangible Assets

Goodwill and intangible assets, not yet available for use

Goodwill and intangible assets not yet available for use are assessed for impairment at each reporting date based on their recoverable amounts, including key assumptions such as the timing of potential commercialization, market size, market share, probability of reaching the market and the discount rates.

Capitalization of intangible assets

The Group capitalizes expenditures for the development of pharmaceuticals to the extent that it is expected to meet the criteria in accordance with IAS 38 — Intangible Assets. The assessment is based on significant judgments made by management, including the technical feasibility of completing the intangible asset so that it will be available for use or sale and assumptions used to demonstrate that the asset will generate probable future economic benefits (e.g., projected cash flow projections, discount rate). Capitalization of expenditures is generally made in the late stage of the development, for example after full approval, depending on when the criteria are deemed to have been met. The reason for this is that before then it is uncertain whether the expenditure will generate future economic benefits and that financing the completion of the asset is not yet guaranteed.

Loss Allowance for Expected Credit Losses for Accounts Receivable

Management makes loss allowance for expected credit losses for accounts receivable that correspond to their maturity. The estimate is based on any increased credit risk, on individual or collective basis, considering reasonable and supportable information, including that which is forward-looking. The allowance for expected credit risk is an estimate based on maturity structure accounts receivable and specific customer knowledge. Generally, invoices are due for payment within 30-45 days.

Loss Carryforwards

The Groups tax losses carried forward have not been recognized as deferred tax assets in the statement of financial position as of December 31, 2022, except for such circumstances where there are future temporary differences that such losses can be used to offset. Deferred tax assets will be recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized.

The Group has identified an uncertain tax position in relation to the ability to use tax loss carried forward in France due to transactions performed historically. The related tax losses carried forward has not been recognized as deferred tax assets in the consolidated statements of financial position.

Key Sources of Estimation Uncertainty

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year. The Group based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising that are beyond the control of the Group. Such changes are reflected in the assumptions when they occur.

Note 3 Operating segments and revenue from Contracts with Customers

Material accounting policy - operating segments

An operating segment is a part of the Group that conducts business activities from which it can generate revenue and incur costs, and for which independent financial information is available. Identification of segments is based on internal reporting to the chief operating decision maker (“CODM”). The CODM for the Group is the Chief Executive Officer (“CEO”). The Group does not divide its operations into different segments and the CODM operates and manages the Group’s entire operations as one segment, which is consistent with the Group’s internal organization and reporting system. The Group’s revenue is attributable to the Parent Company in Sweden and to the U.S. subsidiary Calliditas Therapeutics US Inc. The non-current assets are located in Sweden, the U.S., France and Switzerland.

Material accounting policy - revenue from contracts with customers

The Group is in the business of identifying, developing and commercializing novel treatments in orphan indications. Operating revenue mainly comprises of product sales, outlicensing of Nefecon to our partnerships in Europe, China and Japan and royalty revenue. Revenue is recognized as follows:

F-14

Table of Contents

Product Sales

Revenue from product sales is recognized at the transaction price of goods sold excluding sales tax, rebates and returns. At the time of delivery, when the control of the goods passes to the customer, the revenue is recognized in full, as this represents the single performance obligation in the trans-action. The customer is defined as the specialty pharmacy who dispenses the good to the end user. As the transaction price is dependent on the rebate paid to the patients’ insurance company or government payer, the transaction price is not known upon delivery. This is accounted for by an accrued estimated rebate deduction in the Group based on calculation models considering statistical data, actual amounts incurred and/or historical trends. These liabilities for expected returns and rebates are based on estimates of the amounts received or to be claimed on the related sales. Furthermore, the Group estimates the liability for expected returns of obsolete medicines.

Outlicensing of Product

Revenue attributable to outlicensing Nefecon consisted of the agreement with STADA for Europe, the expansion of Everest Medicines to South Korea and the agreement with Viatris for Japan. Revenue for outlicensing is recognized at a point in time, which occurs when control over the intangible asset is transferred to the counterparty, which was at the time when the agreements with the parties were signed. These contracts with customers consist of fixed consideration as well as variable remuneration in the form of regulatory and commercial milestones, and sales-based royalties. Variable consideration (for example, attributable to future regulatory milestones) is initially considered constrained, as there is significant uncertainty as to whether these will occur. Consideration attributable to sales-based milestones or royalties are not recognized until the sale that results in the right to the milestones or royalties occurs.

Royalty Revenue

Calliditas is, in accordance with agreements, entitled to royalties on goods sold. Revenue recognition is based on royalty reports received, which are based on actual net sales statistics of the licensee. Accrued royalty revenue is recognized in the statement of financial position under prepaid expenses and accrued income.

Significant accounting judgments, estimates and assumptions - revenue recognition

Outlicensing of Product

Revenue for the outlicensing of Nefecon is recognized at the point in time when control of the intellectual property is transferred, while revenue for the provision of certain regulatory services is reported over time as the services are performed. The revenue allocated to the performance obligation for outlicensing is based on the residual approach and consists of the total transaction price for each contract after deducting the stand-alone selling price of all other performance obligations. The allocation of revenue to the performance obligation for regulatory services is based on the expected costs to provide the service, with the addition of a profit margin based on comparable companies. The identification and allocation of the transaction price between these performance obligations hence has a significant impact on the Group's revenue recognition, as the revenue recognition patterns differ between the performance obligations.

Specifically, the significant accounting judgments and estimates within revenue recognition include determining which promises within each contract that are distinct, estimating the expected costs to fulfil the performance obligations that are not based on the residual method, and determining an appropriate profit margin for these. The Group determines the expected costs to complete these performance obligations through an input model based on the expected hours of work required by the Group's personnel, as well as expected costs to be incurred from the Group's suppliers. The Group then determines an appropriate profit margin by identifying comparable peer companies that provide such services separately and bases the margin rate on these. The Group then recognizes revenue for the performance obligation to provide regulatory services as these costs are incurred. These estimates are forward-looking and could be affected by differences between expected and actual costs incurred to fulfil the performance obligations. Management's estimate of the total costs as a measure of progress to completion of the performance obligation hence requires the use of assumptions and estimates.

The revenue contracts also contain variable consideration in the form of regulatory and commercial milestones. Variable consideration is initially considered constrained, as there is significant uncertainty as to whether the associated milestones will occur. Consideration attributable to sales-based milestones or royalties is not recognized until the sale that results in the right to the royalties have occurred. Determining whether the criteria for recognition of the variable remuneration has been met hence has significant effects on revenue recognition and requires significant judgment by Management.

Gross to Net Accounting

Revenue from product sales in the United States is recognized when product is received by the customer and title passes, typically at the time of delivery. There are various sales deductions and rebates that are deducted from the gross sales as part of the revenue recognition process. As the actual sales deductions are not known at the point of sale, estimates are made in determining the initial deduction of rebates, and are then subject to true-up as actual data is obtained. For sales of TARPEYO, returns allowances and prompt pay discounts are estimated based on contract terms and historical return rates or industry averages, if available and those estimates are recorded as a reduction of accounts receivable and as other current liabilities, respectively. Similarly estimates are determined relating to specialty pharma fees, co-pay support redemptions, Medicare/ Medicaid and other rebates, and these estimates are reflected as a component in the accrued expenses and deferred revenue and as a reduction of revenue. Once all related variable considerations are resolved and uncertainties as to collectable amounts are eliminated, estimates are adjusted to actual amounts. Accruals for these estimated amounts are reviewed and adjusted on no less than a quarterly basis, see Note 2.

Set out below is the Group’s revenue from contracts with customers:

Note 8 Leases

The Group applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Group recognizes lease liabilities for future remaining lease payments and right-of-use assets representing the right to use the underlying assets.

Right-of-use assets

The Group recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received.

F-18

Table of Contents

Right-of-use assets are depreciated on a straight-line basis over the esti-mated lease term, which currently is 2 to 8 years for the Group’s leases.

Lease liabilities

At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments less any lease incentives receivable and variable lease payments that depend on an index or a rate. In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the commencement date, because the interest rate implicit in the lease is not readily determinable. Following the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, or a change in the lease payments (e.g., changes to future payments resulting from a change in an index or rate used to determine such lease payments). The Group’s lease liabilities are included in Non-current lease liabilities and other current liabilities in the consolidated statements of financial position (see Note 8 Leases and 20 Financial Risks).

Short-term leases and leases of low-value assets

The Group applies the short-term lease recognition exemption to its short-term leases of equipment (i.e., those leases that have a lease term of twelve months or less from the commencement date). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered to be low value. Lease payments on short-term leases and leases of low value assets are recognized as an expense on a straight-line basis over the lease term.

Future lease payments in accordance with the above are undiscounted.

The leases primarily comprise of leased premises for the Group. The lease agreements for leased premises have terms ending 2024 until 2030 respectively and can be extended unless one of the parties terminates the lease agreements. The Group cannot determine with reasonable certainty whether the extensions will take place based on the Group’s development and has therefore not expected utilization after the terms ending. Future lease payments are linked to the development in the CPI index, but with a limitation on negative index change. Index adjustments are included in the lease liability when they come into force and are then adjusted against the right-of-use asset. Lease of low-value assets consists mainly of storage and office equipment.

Remuneration of Executive Management

Remuneration of the CEO and other executive management comprises base salary, pension benefits and variable remuneration. Other executive management comprise the seven (five) individuals who, together with the CEO, comprise Executive Management. Other executive management are: Chief Financial Officer, Chief Medical Officer, Vice President Regulatory Affairs, President, North America, Group General Counsel and Head of Human Resources.

Pensions

All pension commitments are defined-contribution plans for executive management. The payments made by the Group for defined contribution plans are recognized as expense in the statements of consolidated operations for the period to which they relate. The age of retirement for the CEO is 65 and the pension premium is 20% of base salary. Pension commitments for other Swedish executive management are between 15% and 20% of base salary. The age of retirement is 65 for all other executive management. Defined-benefit pension plans occurs only if required by law or other regulations. In such cases, the defined-benefit level shall be limited to the mandatory level. There are no other pension obligations.

Variable Remuneration

Variable remuneration refers to a variable bonus based on a fixed percentage of base salary. Outcome is based on a vesting period of one year and depends on fulfillment of a combination of predetermined personal targets and business targets. The maximum outcome for the CEO and for other executive management is 60% according to the guidelines for remuneration to executive management.

Severance Pay

A notice period of six months applies if employment is terminated by the CEO. A notice period of twelve months applies if employment is terminated by the Group. The CEO is not entitled to separate severance pay but is eligible to receive a salary during the period of notice. A mutual notice period of three to twelve months, with salary paid, applies between the Group and executive management. No severance pay is paid to Board members.

Guidelines for Executive Remuneration

At the 2023 Annual General Meeting the most recently adopted guidelines for executive remuneration was approved. Remuneration within the Group shall be based on principles of performance, competitiveness and fairness. For additional information of the work of the Board of Directors, please see the Corporate Governance Report on pages 88-93.

Executive management refer to the CEO and other members of the executive management, as well as board members. The guidelines shall apply to employment agreements concluded after the listing on Nasdaq Stockholm, as well as to changes in existing agreements after the listing.

F-23

Table of Contents

The remuneration to the executive management may consist of fixed remuneration, variable remuneration, share and share price-related incentive programs, pension and other benefits. If local conditions justify variations in the remuneration principles, such variations may occur. The fixed remuneration shall reflect the individual’s responsibility and experience level. The fixed remuneration shall be reviewed annually. The executive management may be offered variable remuneration paid in cash. Such remuneration may not exceed 60 percent of the annual fixed remuneration. Variable remuneration shall be connected to predetermined and measurable criteria, designed with the aim of promoting the Groups long-term value creation. Remuneration and other terms of employment for the CEO are prepared by the Remuneration Committee and decided by the Board of Directors. Remuneration and other terms of employment for other members of the executive management are decided by the CEO, in accordance with principles decided by the Board of Directors and the Remuneration Committee.

The Board of Directors is entitled to deviate from the guidelines if the Board of Directors, in a certain case, deems that there are good reasons for the deviation. Decisions as to the current remuneration levels and other conditions for employment of the CEO and the other members of the executive management have been resolved by the Board of Directors. There are no previous payments that have not been due.

Note 10 Share-Based Payments

Option Program

Calliditas implements option programs for employees and key consultants in Calliditas. The options are granted free of charge to participants of the program. The options have a three-year vesting period calculated from the grant date, provided that, with customary exceptions, the participants remain as employees of, or continue to provide services to, Calliditas. Once the options are vested, they can be exercised within a one-year period.

Each vested option entitles the holder to acquire one share in Calliditas at a predetermined price. The price per share is to be equivalent to 115% of the weighted average price that the company’s shares were traded for on Nasdaq Stockholm during the ten trading days preceding the grant date. The options have, at the time of each issue, been valued according to the Black-Scholes valuation model.

Social security costs attributable to equity-related instruments to employees as remuneration for purchased services shall be expensed over the periods during which the services are performed. The cost should then be measured using the same valuation model used when the options were issued. The provision recognized must be revalued at each reporting period on the basis of a calculation of the social security costs that may be paid when the instruments are exercised.

The cost for the remuneration that is recognized in a period is dependent on the original valuation that was made on the date on which the contracts with the participants in the incentive programs were concluded, the number of months of service required for vesting of their options (accruals are made over this period), the number of options that are expected to be vested under the terms of the plans and a continuous reassessment of the value of the tax benefits for the participants under the plans (for determining provisions for social security expenses). Those estimates which affect the cost in a period and the corresponding increase in equity mainly refer to inputs for the valuation of the options. All the options are classified as equity-settled, as vested options are settled in equity. When the options are exercised, the company issues new shares.

Changes and holdings of options for CEO, other executive management and other employees on the opening and closing balance are presented below.

Share Awards

Calliditas implements share awards programs which is a performance-based long-term incentive program for members of the Board of Directors in Calliditas. Calliditas currently has three share award programs ongoing at year-end.

For each share award program, the share awards are vested by 1/3 at the end of each period, provided that the participant is still a member of the Board of Calliditas that day.

In addition to these conditions for vesting, for each share award program, the share awards are subject to performance-based vesting based on the development of Calliditas share price. If Calliditas share price has increased by more than 60 percent, 100 percent of the share awards shall be earned, and if the share price has increased by 20 percent, 33 percent of the share awards shall be vested. In the event of an increase in the share price by between 20 and 60 percent, vesting will be linear. If the share price has increased by less than 20 percent, no vesting will take place. Each share award entitles the holder to receive a share in Calliditas free of charge, provided that the holder is still a member of the Board of Calliditas at the relevant vesting date.

Note 13 Income Tax Expense

Material accounting policy - taxes

Deferred tax is recognized on all temporary differences that arise between the tax value of assets and liabilities and their carrying amounts. Temporary differences attributable to participations in Group companies is not recognized, since it is unlikely that such a reversal will take place in the foreseeable future.

The valuation of deferred tax is based on how the underlying assets or liabilities are expected to be realized or settled. Deferred tax is measured with the application of the tax rates and tax rules decided or announced on the closing date, and that are expected to apply when the deferred tax asset in question is realized or the deferred tax liability is settled. Deferred tax liabilities and deferred tax assets are offset as far as possible within the framework of local laws and regulations on taxation.

Significant accounting judgments, estimates and assumptions - loss carryforwards

The Group's tax losses carried forward have not been recognized as deferred tax assets in the statement of financial position as of December 31, 2022, except for such circumstances where there are future temporary differences that such losses can be used to offset. Deferred tax assets will be recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized.

The Group has identified an uncertain tax position in relation to the ability to use tax loss carried forward in France due to transactions performed historically. The related tax losses carried forward has not been recognized as deferred tax assets in the consolidated statements of financial position.

For calculation of earnings per share after dilution, the weighted-average number of outstanding ordinary shares is adjusted for the dilution effect of all potential ordinary shares, with the exception of treasury shares held by Calliditas. The Parent Company has a category of potential common stock with dilution effect: stock options. These potential common shares are attributable to the options and performance shares granted during the years 2020 – 2023. For additional information see Note 10 Share-Based Payments. If the profit for the year is negative, the options are not considered dilutive. The options also do not impact the numerator in the earnings per share calculation, including the addition of the value of remaining future services to report during the vesting period, exceeding the average market price for the period. There is no dilution effect for issued options with entitlement to subscribe to 6,098,730 shares, since the Group is in a loss position in 2023, 2022, and 2021 respectively. Further, there is no dilution effect for issued share awards with entitlement to receive 100,975 shares, due to performance-based vesting.

For disclosures regarding the number of outstanding shares, refer to Note 25 Equity.

Note 15 Intangible Assets and Impairment Testing

Material accounting policy - intangible assets

Research and development expenses

Development expenditures are recognized as an intangible asset when related development projects meet the criteria for capitalization. The most important criteria for capitalization are that the final product of the development process will generate future economic benefits or the ability of cost-savings capacity, including the technical feasibility of completing the intangible asset. Research and development expense are otherwise recognized as operating expenses. Full market approval has not yet been obtained for the Group’s products and, accordingly, the Group deems that the conditions for capitalizing development expenditures are not met.

Amortization

Until full regulatory market approval has been granted, amortization will not commence in respect of "Licenses and similar rights" that are separately acquired. Following market approval from regulatory authorities, “Licenses and Similar Rights” will be amortized on a straight-line basis over the expected useful life. The Group’s expected finite useful lives are: – Licenses and similar rights – 6-15 years

Impairment of intagible assets

The Group bases its impairment measurement on intangible assets on a probability-adjusted cash flow model. The value of licenses is measured by estimating the expected future cash flows and present value adjustments to take into account the development risk. The valuation takes into account cash flow from potential commercialization during the expected useful life and does not include calculation of any residual value thereafter. The most critical assumptions mainly consist of assumptions about the timing of potential commercialization, market size, market share and probability of reaching the market.

When assessing the impairment requirement for goodwill, this is grouped at the lowest levels for which there are separately identifiable cash flows. Calliditas has made the assessment that the Group’s operations as a whole comprise a cash-generating unit.

Significant accounting judgments, estimates and assumptions - intangible assets

The Group’s intangible assets are attributable to the Group acquiring the rights to the NOX platform, as well as goodwill in connection with the acquisition of Genkyotex SA. For goodwill and intangible assets not yet available for use the Group assesses for impairment at each reporting date based on their recoverable amounts, including key assumptions such as the timing of potential commercialization, market size, market share, probability of reaching the market and the discount rates.

Goodwill and intangible assets, not yet available for use

The Group conducts impairment testing, at least annually, for goodwill and intangible assets not yet available for use. The recoverable amount of the cash-generating unit is determined by calculating the value in use. This calculation requires certain judgments and assumptions to be made. As of December 31, 2023, the Group’s goodwill amounted to SEK 48,584 and other intangible assets amounted to SEK 430,754.

Capitalization expenditures for the development

The Group capitalizes expenditures for the development of pharmaceuticals to the extent that it is expected to meet the criteria in accordance with IAS 38 — Intangible Assets. The decision to capitalize is based on significant judgments made by management, including the technical feasibility of completing the intangible asset so that it will be available for use or sale and assumptions used to demonstrate that the asset will generate probable future economic benefits (e.g., projected cash flow projections, discount rate). The Group’s expenditures for the development of pharmaceuticals were not deemed to meet the capitalization criteria for the year ended December 31, 2023, and was thus expensed. Capitalization of expenditures are generally made in late stage of the development, for example after full approval, depending on when the criteria are deemed to have been met. The reason for this is that before then it is uncertain whether the expenditure will generate future economic benefits and that financing the completion of the asset is not yet guaranteed.

US Food and Drug Administration (FDA) has granted accelerated approval for TARPEYO® in the U.S. and the European Commission has granted conditional marketing authorization for Kinpeygo® in Europe (EEA). Continued approval may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial and, accordingly, the conditions for capitalizing development expenditures may change to be reflected in the assumptions when they occur.

Intangible assets consist of licenses and similar rights of SEK 430,754 and goodwill of SEK 48,584 as of December 31, 2023.

Intangible assets are from the acquisition of the NOX-platform and associated goodwill. The net book value of the NOX-platform amounts to SEK 430,753 as of December 31, 2023. The NOX-platform constitutes a technology, including the lead compound setanaxib, enables the identification of orally available small molecules which selectively inhibit specific NOX enzymes that amplify multiple disease processes such as fibrosis and inflammation. The estimated fair value of the NOX platform was determined using the discounted cash flow (DCF) method, adjusted for the likelihood of occurrence. During the year, an impairment of SEK 32.1 million was recognized, and was related to the in-licensing Budenofalk. The decision to close was attributed to regulatory challenges.

Impairment Testing

Goodwill

The assessment of the value of the Group’s goodwill is based on the fair value less cost of disposals for the smallest cash-generating unit, which for Calliditas is deemed to be the full Group. The impairment measurement is based on a probability-adjusted cash flow model, measured at Level 3 of the fair value hierarchy, where the most critical assumptions mainly consist of assumptions about the timing of potential commercialization, market size, market share and probability of reaching the market. The period for the forecast cash flow extends to 2035, where no terminal growth rate has been taken into account. As of December 31, 2023, the Group’s goodwill amounted to SEK 48,584. There is no impairment for the year ended December 31, 2023.

These assets consist of the NOX platform, which are tested, at least, annually for impairment requirement. The assessment of the value of the technology and the rights is based on the fair value less cost of disposals of the assets. The fair value less cost of disposals is based on cash flows that are expected to be generated over the remaining life of the asset.

When the technology and the rights are tested for impairment requirement, a number of assumptions are made, where the most critical assumptions mainly consist of the timing of potential commercialization, market size, market share, probability of reaching the market and the discount rate. The earlier in the chain of development the project is, the higher the risk. As it passes through the defined phases of development, the likelihood of reaching the market increases. The review of the technology and the rights showed no impairment requirement except for impairment of Budenofalk 3 mg oral capsule amounted to SEK 32,132.

The carrying amount for other items above is an approximation of the fair value, which is why these items are not separated into levels according to the fair value hierarchy.

Note 20 Financial Risks

Significant accounting judgments, estimates and assumptions - expected credit losses

Management makes allowance for expected credit losses for accounts receivable that correspond to their maturity. The estimate is based on any increased credit risk, on an individual or collective basis, considering reasonable and supportable information, including that which is forward-looking. The allowance for expected credit risk is an estimate based on maturity structure accounts receivable and specific customer knowledge. Generally, invoices are due for payment within 30-45 days.

Through its operations, the Group is exposed to a variety of financial risks: credit risk, market risk (currency risk, interest rate risk and other price risk), refinancing risk, liquidity risk and external risk. The Group’s overall risk management focuses on the unpredictability of the financial markets and it endeavors to minimize potentially unfavorable effects on the Group’s financial results.

The Group’s financial transactions and risks are managed centrally through the Group’s CFO and CEO. The overall objective for financial risks is to provide cost-efficient financing and liquidity management and to ensure that all payment commitments are managed in a timely manner.

F-36

Table of Contents

The Board prepares written policies for both the overall risk management and for specific areas, such as credit risks, currency risks, interest rate risks, refinancing risks, liquidity risks and the use of derivative instruments and investment of surplus liquidity.

Credit Risk

Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument, leading to a financial loss for the Group. The Group’s exposure to credit risk, except for accounts receivable as described below, is limited to deposits with banks with high credit ratings, which means the Group is of the opinion that there is no material credit risk related to deposits with bank.

Credit risk accounts receivable

The payment terms amount to 30-45 days depending on the counterparty. Of accounts receivables net, SEK 113,115 is to an individual major customer as of December 31, 2023.

Market Risks

Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. The type of market risk that impacts the Group is currency risk. The Group does not currently have any loans or holdings that expose the group to interest rate risk or other price risk.

Interest Rate Risk

Interest rate risk is the risk that would be adversely impacted by changes in interest rates resulting from increased interest costs. Calliditas exposure to interest rate risk mainly occurs through external loans and cash. Calliditas financing sources primarily consist of equity and borrowings. In the case of interest-bearing liabilities, the Group is exposed to interest rate risk. The Group does not currently have any variable interest rate and as of December 31, 2023 the carrying amount of Non-current interest-bearing liabilities are in all material respect an approximation of the present value.

Foreign Currency Risk

Foreign currency risk is the risk that the fair value or future cash flows of an exposure will fluctuate because of changes in foreign exchange rates. The primary exposure derives from the Group’s purchases in foreign currencies. This exposure is known as transaction exposure. Currency risk is also found in the translation of the assets and liabilities of foreign operations to the Parent Company’s functional currency, known as translation exposure.

As presented in the table above, the Group’s primary transaction exposure is in Euro and U.S. dollar. A 10% stronger Euro against the Swedish Krona would have a negative impact on profit after tax and equity of approximately SEK 29,332 (SEK 23,132, SEK 909). A 10% stronger U.S. dollar against the Swedish Krona would have a negative impact on profit after tax and equity of approximately pos. SEK 49 (SEK 9,624, SEK 22,402).

Translation Exposure

The Group also has translation exposure that arises on the translation of earnings and net assets of foreign subsidiaries to the Swedish Kronor. Translation against U.S. dollar amounted to SEK 85,240 and SEK 48,771 as of December 31, 2023 and 2022, respectively. A 10% stronger Swedish Krona against the U.S. dollar would have a positive impact on equity of approximately SEK 8,524 and SEK 4,877 as of December 31, 2023 and 2022, respectively. Translation against Euros amounted to SEK 391,568 and SEK 446,646 as of December 31, 2023 and 2022, respectively. A 10% stronger Swedish Krona against Euros would have a positive impact on equity of approximately SEK 39,157 and SEK 44,665 as of December 31, 2023 and 2022, respectively. Translation against Swiss franc amounted to (SEK 794,449) and (SEK 537,550) as of December 31, 2023 and 2022, respectively. A 10% stronger Swedish Krona against Swiss franc would have a negative impact on equity of approximately SEK 79,445 and SEK 53,755 as of December 31, 2023 and 2022, respectively.

The Group also has a translation exposure arising from the translation of foreign accounts payable to the Swedish Kronor. This exposure amounted to SEK 24,606 and SEK 19,377 as of December 31, 2023 and 2022, respectively, and in U.S. dollars SEK 68,391 and SEK 80,655 in Euros as of December 31, 2023 and 2022, respectively. A 10% stronger U.S. dollar against the Swedish Krona would have a negative impact on profit after tax and equity of approximately SEK 2,461 and SEK 1,938 as of December 31, 2023 and 2022, respectively. A 10% stronger Euro against the Swedish Krona would have a negative impact on profit after tax and equity of approximately SEK 6,839 and SEK 8,065 as of December 31, 2023 and 2022, respectively.

Refinancing Risk

Refinancing risk refers to the risk that cash are not available and the risk that financing cannot be secured at a reasonable cost or at all. The Group is financed with equity, external loan financing and income from operations. The main risks relate to not receiving further contributions from shareholders, external loans or in the event of continued negative cash flow from operations.

Liquidity Risk

Liquidity risk is the risk that the Group encounters difficulties in meeting its obligations associated with financial liabilities. The Board manages liquidity risks by continuously monitoring cash flow so that it can reduce liquidity risk and ensure its solvency. Given that the Parent Company currently does not have its own earning ability, the Board carries out long-term work with owners and independent investors to ensure that liquidity is available to the Parent Company when a need arises.

The Group’s contractual and undiscounted interest payments and repayments of financial liabilities are presented in the table below. Amounts in foreign currency were translated to SEK at the closing balance rate. Financial instruments with variable interest rates were measured at the rate on the closing balance. Liabilities were included in the earliest period when repayment is required. For future lease payments see Note 8 Leases.

During 2023, Calliditas had signed and fully drawn a term loan of EUR 92 million with funds managed by Athyrium Capital Management, LP. The fair value of the loan at the end of the period amounts to SEK 966,1 million. The net book value of the loan at the end of the period, adjusted for transaction costs and accrued interest expense, is 939,5 million. The interest rate on the loan is 9 % per annum with a maturity to December 2027, which is recognized in Financial expenses. The credit agreement contains quarterly financial covenants specifying minimum cash liquidity and minimum product revenue. The credit agreement contains customary affirmative and negative covenants for a senior secured loan. Failure to maintain compliance with the covenants would result in an event of default under the Athyrium Credit Agreement, which could result in enforcement action, including acceleration of amounts due under the Athyrium Credit Agreement.

Note 21 Inventories

Inventory is recognized as the lower of the acquisition cost and the net realizable value. The acquisition cost for completed goods and goods being manufactured comprises raw materials and other direct costs and applicable indirect manufacturing costs. The net realizable value is the estimated sale price in operating activities after deduction of sales cost.

Note 26 Provisions

Material accounting policy-provisions

A provision differs from other liabilities as there is uncertainty in the time of payment or the size of the amount to settle the provision. A provision is reported in the group's statement of financial position when there is an existing legal or informal obligation as a result of an event that has occurred, and it is likely that an outflow of financial resources will be required to settle the obligation and a reliable estimate of the amount may be done. Provisions are made with the amount that is the best estimate of what is required to settle the existing obligation at the balance sheet date. Where the effect of when in time payment takes place is significant, provisions are calculated by discounting the expected future cash flow.

Note 27 Contingent Consideration

Material accounting policy - contingent consideration

The Group's contingent consideration is classified as financial liabilities that are recognized at fair value through profit or loss. Measurement is both initially and in subsequent periods made at fair value in the Group’s consolidated statements of financial position, where changes in fair value are recognized in the Group’s consolidated statements of income. The components of the change in fair value relating to exchange rate effects are recognized in net financial items and other changes in fair value are recognized in operating profit or loss.

Contingent Consideration

In connection with the business combination of Genkyotex SA, the Group has undertaken to make potential future milestone payments relating to contingent consideration, provided that future regulatory approvals or marketing authorizations regarding setanaxib are obtained. The transaction stipulates the following contingent consideration:

Milestone 1: EUR 30.0 million if Genkyotex is granted the right to commercially manufacture, market and sell setanaxib in the United States by the FDA.

Milestone 2: EUR 15.0 million if Genkyotex is granted the right to commercially manufacture, market and sell setanaxib in the European Union by the European Commission.

Milestone 3: EUR 10.0 million if Genkyotex is, by the FDA or European Commission, granted the right to commercially manufacture, market and sell setanaxib in the United States or European Union for the treatment of IPF or Type 1 Diabetes.

The fair value of contingent consideration is measured at Level 3 of the fair value hierarchy. Contingent consideration is recognized as a financial liability in the consolidated statements of financial position, which is revalued at fair value each reporting period. Any revaluation gains and losses are recognized in the consolidated statements of income. The contingent consideration has been computed in accordance with the present value method and the probability has been taken into account if and when the various milestones will occur. The calculations are based on a discount rate of 12.2 percent. The most significant input affecting the valuation of the contingent consideration is the company’s estimate of the probability of the milestones being reached and the change of the year was primarily derived from the assumptions regarding the probability of success in the clinical trials.

The Group has assessed the weighted average probability of outcome at 19.7% and 20.8% as of December 31, 2023 and 2022, respectively. A 10% higher probability of success in the clinical trials would have a negative impact on profit after tax of approximately SEK 5,656 and SEK 7,588 as of December 31, 2023 and 2022, respectively. A higher probability of success in the clinical trials will increase the fair value of the liability and a lower probability will decrease the fair value. There are no interrelationships between unobservable inputs used in the fair value measurement.

Risks connected to defined-benefit pension plans

Through its defined-benefit pension plans for post-employment benefits, the Group is exposed to a number of risks. The most significant risks are:

Life expectancy assumption: Most of the pension commitments entail that the employees covered by the plan will receive life-long benefits and, accordingly, the longer life expectancy assumptions will result in higher pension liabilities. This is particularly significant in the Swiss plan, in which inflation increases result in higher sensitivity to changes in life expectancy assumptions.

Inflation risk: Some of the plan’s pension commitments are linked to inflation. Higher inflation leads to higher liabilities (although, in most cases, a ceiling has been set for the level of inflation to protect the plan against exceptional increases in inflation). Most of the plan assets are either unaffected by (fixedrate bonds), or weakly correlated with (shares) inflation, which means that an increase in inflation will also increase the deficit.

Discount rate: A decrease in the interest rate on corporate bonds will increase the liabilities of the plan, although this will partially be offset by an increase in the value of the bond holdings. The Swiss pension plan is covered by The Swiss Federal Act on Occupational Retirement, Survivor’s and Disability Pension Plans (BVG).

The French pension plan is covered by the labor law and the collective bargaining agreement of the pharmaceutical industry. The Swiss and French plans are based on final salary.

The amounts above show what the value of the pension obligation would have been assuming the change in the individual assumption. The sensitivity analyses are based on a change in one assumption, with all other assumptions remaining constant. In practice, this is highly unlikely to occur and some of the changes in the assumptions may be correlated. When calculating the sensitivity of the defined-benefit obligations to significant actuarial assumptions, the same method (present value of the defined-benefit obligation applying the projected unit credit method at the end of the reporting period) has been applied as when calculating the pension liability recognized in the consolidated statements of financial position.

As the defined benefit pension plans in France are deemed to be insignificant for the Group, no further information has been provided.

Contributions to plans for post-employment benefits are expected to be SEK 941 and SEK 813 in 2023 and 2022, respectively. The weighted average maturity of the obligation is an estimated 23.1 and 18.6 years in 2023 and 2022, respectively.
