Our Business

ImmunityBio, Inc. is a clinical-stage biotechnology company developing next-generation therapies and vaccines that complement, harness, and amplify the immune system to defeat cancers and infectious diseases. We strive to be a vertically-integrated immunotherapy company designing and manufacturing our products so they are more effective, accessible, more conveniently stored, and more easily administered to patients.

Our broad immunotherapy and cell therapy platforms are designed to attack cancer and infectious pathogens by activating both the innate immune system—natural killer (NK) cells, dendritic cells, and macrophages—and the adaptive immune system—B cells and T cells—in an orchestrated manner. The goal of this potentially best-in-class approach is to generate immunogenic cell death thereby eliminating rogue cells from the body whether they are cancerous or virally infected. Our ultimate goal is to employ this approach to establish an “immunological memory” that confers long-term benefit for the patient.

Our business is based on the foundation of multiple platforms that collectively act on the entire immune response with the goal of targeted, durable, coordinated, and safe immunity against disease. These platforms and their associated product candidates are designed to overcome the limitations of the current standards of care in oncology and infectious diseases, such as checkpoint inhibitors and antiretroviral therapies. We have established one of the most comprehensive portfolios of immunotherapy and vaccine platforms, which include:

We believe that our innovative approach to orchestrate and combine therapies for optimal immune system response will become a therapeutic foundation across multiple clinical indications. Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, Anktiva, our novel antibody cytokine fusion protein, has received Breakthrough Therapy and Fast Track designations in combination with BCG from the U.S. Food and Drug Administration (FDA) for BCG-unresponsive NMIBC CIS. Based on the reported results of the trial, we have initiated discussions with the FDA to file a BLA for Anktiva (to be branded VesAnktiva™ for intravesical administration) plus BCG for BCG-unresponsive NMIBC CIS. Additionally, we believe data from multiple clinical trials indicates Anktiva has broad potential to enhance the activity of therapeutic monoclonal antibodies (mAbs), including checkpoint inhibitors (e.g., Keytruda®), across a wide range of tumor types.

Table of Contents

Our platforms, which include 17 first-in-human therapeutic agents, are being studied in 26 actively recruiting clinical trials—17 of which are in Phase 2 or 3 development—across 13 indications in liquid and solid tumors, including bladder, pancreatic and lung cancers. These are among the most frequent and lethal cancer types for which there are high failure rates for existing standards of care or, in some cases, no available effective treatment. In infectious disease, our pipeline currently targets such pathogens as the novel strain of the coronavirus (SARS-CoV-2) and human immunodeficiency virus (HIV). We believe SARS-CoV-2 currently lacks a vaccine that provides long-term protection against the virus, particularly its variants, while HIV affects tens of millions of people globally and currently has no known cure.

We have established Good Manufacturing Practice (GMP) manufacturing capacity at scale with cutting-edge cell manufacturing expertise and ready-to-scale facilities, as well as extensive and seasoned research and development (R&D), clinical trial, and regulatory operations and development teams.

Our Strategy

We seek to become the leading global immunological therapeutics company by creating the next generation of immunotherapies to address serious unmet needs within oncology and infectious diseases. To achieve this goal, the key elements of our strategy include:

•advancing the approval and commercialization of our lead antibody cytokine fusion protein, Anktiva, as an integral component of immunotherapy combinations, including those with checkpoint inhibitors;

•continuously scrutinizing our clinical pipeline and assessing our strategic priorities to maximize opportunities for regulatory approval and to meet unmet medical needs;

•accelerating our immunotherapy platform and product candidates with registrational intent to address difficult-to-treat oncological and infectious disease indications;

•continuing to prospect, license, and acquire technologies to complement and strengthen our platforms and product candidates, both as single agent and combination therapies, in order to activate and coordinate the innate and adaptive immune system to generate cellular memory against multiple tumor types and infectious diseases;

•optimizing investment in our discovery, development, and manufacturing capabilities for our next-generation targeted antibody cytokine fusion proteins and vaccine candidates, as well as for cell therapies;

•advancing our formulations and delivery mechanisms to make our promising biotechnology product candidates available to the broadest population possible; and

•cultivating new and expanding existing collaborations for our multi-stage pipeline to efficiently scale globally.

Our Next-Generation Platforms

1.Antibody Cytokine Fusion Proteins

Antibody cytokine fusion proteins such as Anktiva are a novel class of biopharmaceuticals that enhance the therapeutic potential of cytokines, and promote lymphocyte infiltration at a site of disease, improving immune response. Anktiva (N-803) is a novel interleukin-15 (IL-15) superagonist fusion protein consisting of high-affinity mutant IL-15N72D fused to the IL-15 receptor α sushi subunit and linked to the Fc portion of IgG1 Fc. The novel antibody cytokine fusion protein specifically increases the activity of two critical aspects of the immune system—NK cells and cytotoxic (tumor cell killing) CD8 T-cells—and exerts its effects via beta gamma, rather than alpha, T-cell receptor binding and avoids regulatory T-cell (T-reg) stimulation that might dampen the pro-immune effect. Anktiva has improved pharmacokinetic properties, longer persistence in lymphoid tissues and enhanced anti-tumor activity compared to native, non-complexed IL-15 in vivo. Multiple Phase 1 and Phase 2 trials in both liquid and solid tumors have been completed through the date of this Annual Report in over 700 patients. Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, Anktiva has been awarded both Breakthrough Therapy and Fast Track designations by the FDA for the treatment of BCG-unresponsive NMIBC CIS as well as Fast Track designation for BCG-unresponsive NMIBC papillary and BCG-naïve NMIBC CIS. Based on patient data that was submitted with our application to obtain the Breakthrough Therapy designation in BCG-unresponsive NMIBC CIS, Anktiva achieved its primary endpoint of a complete response (CR) rate at any time in the ongoing registrational Phase 2/3 trial. We believe that other indications with registration potential include BCG unresponsive papillary bladder cancer, lung cancer, pancreatic cancer, glioblastoma multiforme (GBM) and triple-negative breast cancer (TNBC). We have initiated discussions with the FDA to file a BLA for Anktiva (to be branded VesAnktiva for intravesical administration) plus BCG for BCG-unresponsive NMIBC CIS.

In addition to Anktiva, we are developing bi-specific fusion proteins targeting CD20, PD-L1, IL-12, and TGF-ß to further enhance NK and T-cell activation directed to the infectious disease or tumor microenvironment, and to modulate the systemic and local immune response to accelerate immunogenic cell death. Prioritized product candidates in preclinical development include antibody cytokine fusion proteins N-820 (targeting CD20), N-809 (targeting PD-L1), N-812 (delivering IL-12 to necrotic tumor cells), and N-830 (delivering a TGF-ß Trap to necrotic tumor cells).

2.DNA, RNA, and Recombinant Protein Vaccine Technologies

We have developed and acquired rights to multiple vaccine delivery technologies for infectious diseases to target key viruses, including SARS-CoV-2, and for oncology to deliver common tumor-associated antigens (TAAs), and neoepitopes (expressed only by cancer cells). These technologies can deliver DNA, self-amplifying RNA (saRNA), and subunit proteins to induce B and T cell memory due to the activation of both CD4+ and CD8+ T cells along with antibody (humoral) responses. We believe a “mix-and-match” strategy (i.e., a heterologous approach combining different vaccine platforms) could provide maximal immune protection against current and future COVID-19 variants such as Delta and Omicron. Our key vaccine delivery technologies include:

a.Self-amplifying RNA

Synthetic RNA technology has quickly emerged for prophylactic and therapeutic vaccines in part because it allows for rapid, scalable, and cell-free manufacturing as evidenced by the adoption of SARS-CoV-2 RNA vaccines. We believe our saRNA technology (licensed from the Infectious Disease Research Institute (IDRI) both directly and, in the case of SARS-CoV-2, through our joint venture formed with Amyris, Inc. (Amyris) in December 2021) represents a significant improvement over existing RNA technologies. Our saRNA constructs include a nanostructured lipid carrier (NLC) formulation important for thermal stability and facilitating the substitution of genetic sequences and have demonstrated an ability to vaccinate with multi-valent strains. The self-replicating capability allows for increased potency by maintaining auto-replicative activity derived from the RNA virus vector, while the self-amplifying capability may increase the duration and breadth of immunity. Preclinical studies in small animal and non-human primate (NHP) models have shown that the saRNA delivery vehicle results in potent humoral and cell-based immunogenicity. Phase 1 first-in-human trials of saRNA for COVID-19 are anticipated to begin in the first half of 2022.

b.Second-generation adenovirus hAd5 vector

Adenovirus is a well-established viral vector and can be utilized as a vaccine to stimulate the immune system. Our human adenovirus serotype 5 (hAd5) technology has unique deletions in the early 1, (E1), early 2 (E2b) and early 3 (E3) regions (hAd5 [E1-, E2b-, E3-]), which allows it to be effective in the presence of pre-existing adenovirus immunity and lowers the risk of generating de novo vector-directed immunity. We have several hAd5 product candidates, which have been studied in multiple Phase 1 and 2 clinical trials as potential vaccines for the treatment of SARS-CoV-2 and certain cancers. Importantly, these product candidates have shown an ability to overcome previous adenovirus immunity in cancer patients and in preclinical models. The hAd5 technology has also been used with common TAAs to establish memory T cells in multiple clinical trials. Our SARS-CoV-2 candidate uses a combination of S-Fusion and N-ETSD, our novel constructs of COVID-19 S+N proteins, which has been shown to generate CD4+ and CD8+ T cell mediated immunity and neutralizing antibodies in Phase 1 trials. Our vaccine candidate is currently being studied in our SISONKE Boost Trial (COVID 4.010) in South Africa now in Phase 3.

c.Recombinant subunit proteins

Our yeast vaccine platforms have been studied in both oncology and infectious disease. The Tarmogen platform (licensed from our subsidiary GlobeImmune, Inc. (GlobeImmune)) has been administered to over 400 patients with cancer or infectious diseases in FDA-regulated clinical trials. This platform technology consists of a heat-killed, recombinant S cerevisiae yeast-based vaccine engineered to express immunogens such as TAAs, pathogen antigens, and tumor-specific neoepitopes. Immunization with this platform elicits CD4+ and CD8+ T cell responses capable of eliminating tumor cells or pathogen-infected cells. Our recombinant receptor-binding domain (RBD) pichia-based antigen (licensed from the Baylor College of Medicine (BCM), which was developed at the Texas Children’s Hospital Center for Vaccine Development) with 3M-052/Alum adjuvants and related technology (licensed from IDRI and 3M Company (3M) and affiliates) has been shown to provide protection against SARS-CoV-1, SARS-CoV-2 (and variants of concern), and animal coronaviruses. Phase 1 clinical trials of this subunit protein and 3M-052 adjuvants are anticipated to begin in the first half of 2022.

d.Bacterial-based endosomal delivery vectors

EDVs are a first-in-class, cyto-immunotherapy platform that utilizes antibody-targeted, bacterially-derived, 400 nm diameter non-living “nanocells” to release high concentrations of super-cytotoxic drugs, molecularly-targeted drugs, or small interfering RNAs (siRNAs)/microRNAs (miRNAs) and can be engineered to activate iNKT cells (see below—Invariant natural killer T cells (iNKT)). We signed a binding term sheet with EnGeneIC Pty Limited (EnGeneIC) to integrate their patented EDV to explore clinical development in the treatment of COVID-19 and pancreatic cancer.

3.Toll-Like Receptor Activating Adjuvants

Adjuvants are either synthetic or naturally occurring molecules that activate toll-like receptors (TLRs) thereby enhancing the humoral and cell-mediated immune response of vaccines. There are 10 human TLRs expressed either on the inside or outside of the immune cell and their function is to recognize foreign substances expressed by pathogens. Once activated, these TLRs stimulate danger signals to the immune cells initiating an immune response. We have licensed adjuvants and related technology from IDRI and 3M Company and its affiliates to incorporate with the vaccine delivery platforms described above and have access to multiple toll receptor activators, including TLR 4, TLR 7, and TLR 8. The 3M-052/Alum adjuvant formulation is in Phase 1 trials in the U.S. with an HIV antigen and has been well-tolerated and highly immunogenic. A Phase 1 clinical trial for SARS-CoV-2 of this 3M-052 adjuvant in combination with a subunit protein is anticipated to begin in the first half of 2022. We also plan to use these adjuvants in vaccines for the treatment of tuberculosis, schistosomiasis, and influenza.

4.NK Cell Therapy

ImmunityBio has one of the most comprehensive clinical-stage natural killer cell platforms, which has demonstrated the ability to induce cell death in cancers and virally-infected cells through a variety of concurrent mechanisms including innate killing, antibody-mediated killing, chimeric antigen receptor (CAR)-directed killing, and a combination of both antibody-mediated and CAR-directed killing.

a.Off-the-shelf natural killer (NK) cells

Natural killer cells (NK cells) are a type of cytotoxic lymphocyte critical to the innate immune system. NK cells show spontaneous cytolytic activity against cells under stress such as tumor cells and virally-infected cells. After activation, NK cells also secrete several cytokines such as interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), granulocyte macrophage colony-stimulating factor (GM-CSF), and chemokines that can modulate the function of other innate and adaptive immune cells. Cytotoxic cell lines (including our NK-92) have been established from patients with clonal NK-cell lymphoma. Those cells can be expanded in culture in the presence of cytokines (IL-2, IL-15). Our “off-the-shelf” NK cell platform has been molecularly engineered in a variety of ways to boost its killing capabilities against cancers and virally-infected cells. Unlike normal natural killer cells, our aNK cells do not express the key inhibitory receptors that diseased cells often exploit to turn off the killing function of NK cells and escape elimination. We have genetically engineered our aNK cell platform to overexpress high-affinity CD16 receptors that bind to antibodies. These antibody-targeted haNK cells are designed to directly bind to IgG1-type antibodies, such as avelumab, trastuzumab, cetuximab, and rituximab, with the intention of enhancing the cancer-killing efficacy of these antibodies by boosting the population of competent natural killer cells that can kill cancer cells through antibody dependent cellular cytotoxicity (ADCC).

Our most advanced line of off-the-shelf product candidates is an innovative, bioengineered combination that incorporates all the features of our haNK platform together with a CAR (t-haNK). Product candidates under this platform have three modes of killing: innate, antibody-mediated, and CAR-directed killing. These product candidates also include one or more additional expression elements such as functional cytokines, chemokines and trafficking factors. These product candidates are intended to be combined with commercially available therapeutic antibodies to effectively target either two different epitopes of the same cancer-specific protein or two entirely different cancer specific proteins. Key trials studying our t-haNK product candidates have been initiated—PD-L1 t-haNK in Phase 1/2 trials in TNBC, and Phase 2 trials in pancreatic and GBM—and CD19 t-haNK has been cleared to commence Phase 1 testing in non-Hodgkin’s lymphoma. We believe we have a pipeline of other prominent CARs for t-haNK, including HER2 and epidermal growth factor receptor (EGFR), which are advancing through clinical-enabling studies, among others, which will enable us to potentially address an even broader range of cancers as part of a chemotherapy-free combination regimen. In March 2021, in collaboration with the National Cancer Institute (NCI), our PD-L1 t-haNK was reported to be a potent cell therapy agent against myeloid-derived suppressor cells (MDSC) and overcome T cell escape in multiple types of resistant tumors (Fabian et al 2020). In January 2022, we reported on the results of our metastatic pancreatic cancer trial using PD-L1 t-haNK in combination with Anktiva. These findings, which were reported at the ASCO Gastrointestinal Conference in January 2022, showed a median overall survival of 6.3 months in patients who had progressed after two prior lines of therapy, more than doubling historical survival. We plan to meet with the FDA in 2022 to discuss a potential path for the approval of combination therapies for pancreatic cancer.

b.Autologous and allogenic memory-like cytokine-enhanced NK cells (M-ceNK)

Memory-like cytokine-enhanced NK cells are a unique set of lymphocytes that differentiate after a brief pre-activation with interleukin-12 (IL-12), IL-15 and IL-18 and exhibit enhanced responses to cytokine re-stimulation that include enhanced IFN-γ production and cytotoxicity against leukemic cell lines. These cells have been isolated and characterized by their unique cell-surface marker profile and their highly desirable feature of immune-memory, marked by their pronounced anti-cancer activity for weeks to months in duration, which has made these cells a research focus for more than a decade. We have developed a unique ability to generate a portfolio of distinct M-ceNK cell products through the application of our proprietary GMP-in-a-Box bioreactors and cytokines and our proprietary methods and overall expertise in scale manufacturing of NK cell-based products. In May 2021, the FDA authorized the company to conduct a first-in-human trial to study the M-ceNK platform in solid tumors (QUILT 3.076). An initial clinical trial showed that healthy and patient-derived M-ceNK killed NK-resistant tumor cells.

c.Invariant natural killer T cells

iNKT cells are unique T cells that express an invariant aβ T-cell receptor (TCR) and a number of cell surface molecules in common with NK cells. Although they comprise less than 1% of peripheral blood mononuclear cells (PBMCs), they are important immunoregulatory cells that can quickly produce large amounts of cytokines. iNKT cell-derived cytokines and chemokines recruit and activate dendritic cells and can modulate several other cell types, including B cells, CD4+ and CD8+ T cells, NK cells, macrophages and neutrophils. iNKT cells recognize glycolipid antigens presented by the non-polymorphic major histocompatability complex (MHC) Class I-like molecule, CD1d in contrast to conventional T cells, which primarily recognize peptide antigens presented by MHC molecules. We entered into a binding term sheet with EnGeneIC to license EDV, which can be engineered to activate iNKT cells, to explore clinical development in the treatment of COVID-19 and pancreatic cancer. We plan on developing iNKT-cell vaccines, including for the prevention of COVID-19. EDV is now in Phase 3 clinical trials in Australia. Through the date of this Annual Report, the initial 2x109 EDV IM dose has shown little to no adverse events (AEs) with what we believe is promising antibody, memory B cell and T cell activity. In addition to expanding this trial in Australia and the U.S., we are exploring using the EDV technology in combination with our other vaccine constructs for select future trials.

5.Damage-Associated Molecular Patterns Inducers

DAMPs are released in response to cell stress and death, and elicit potent sterile inflammation. Recent evidence suggests that DAMPs may also have a key role in the development of cancer as well as in the host response to cytotoxic anti-tumor therapy. DAMPs may play a protective role by alerting the immune system to the existence of dying tumor cells, thereby triggering immunogenic tumor cell death. Albumin bound chemo modulators and tumor associated antigen regulators target delivery of the chemotherapy agent to the tumor microenvironment, activate tumor killing macrophages and/or enable a tumor suppressive microenvironment.

a.Aldoxorubicin

Aldoxorubicin is an albumin-associated anthracycline chemo modulator designed to target immune evasion in cancer. Aldoxorubicin has the same cytotoxic mechanism of action as doxorubicin, which is currently approved for use in 14 indications, including breast cancer, Hodgkin’s lymphoma and small cell lung cancer (SCLC), but also has unique pharmacological properties resulting in lower cardiotoxicity as shown in Phase 2 and Phase 3 clinical trials for soft tissue sarcoma previously conducted by CytRx Corporation (CytRx). CytRx out-licensed global development, manufacturing, and commercialization rights for aldoxorubicin to us in 2017. The investigative therapeutic is currently in a Phase 2 trial in pancreatic cancer in combination with Anktiva and PD-L1 t-haNK, and we plan to include it in a new randomized, multi-center, Phase 2 GBM trial (QUILT 3.078) currently being developed to evaluate the efficacy and safety of the combinations of Anktiva, aldoxorubicin, PD-L1 t-haNK, and bevacizumab.

b.Nanatinostat

VRx-3996 (nanatinostat), an orally available histone deacetylase (HDAC) inhibitor, is being developed by Viracta. Nanatinostat is selective for specific isoforms of Class I HDACs, which is key to inducing viral genes that are epigenetically silenced in EBV-associated malignancies. In preclinical studies, nanatinostat has been shown to reactivate silenced transgenes in tumor cells thereby turning them into preferential targets for NK cell killing, while also serving to broadly stimulate a patient’s immune system, offering the potential for improved clinical responses in cancer patients. The activity of HDAC inhibitors are believed to be based on the upregulation of natural killer group 2D (NKG2D) ligand expression on cancer cells, which serve as “eat-me” signals for NK cells and can drive NK proliferation, activation and cancer cell killing. We entered into an agreement with Viracta under which we were granted exclusive worldwide rights in patents and know-how related to nanatinostat for use in combination with our platform of NK cell therapies.

1.Non-Muscle Invasive Bladder Cancer (QUILT 3.032) (QUILT 2.005)

In the U.S., bladder cancer is the fourth most commonly-diagnosed solid malignancy in men and twelfth in women. The American Cancer Society estimates there will be 81,180 new cases and 17,100 deaths from bladder cancer in 2022. There is an urgent, unmet need to treat NMIBC and avoid radical cystectomy of the bladder in an attempt to control the disease. Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, Anktiva has been awarded both Breakthrough Therapy and Fast Track designations by the FDA for the treatment of BCG-unresponsive NMIBC CIS as well as Fast Track designation for BCG-unresponsive NMIBC papillary and BCG-naïve NMIBC CIS. In our QUILT 3.032 trial, the company reported that the primary end points were met for both BCG-unresponsive NMIBC CIS and papillary in October 2021 with a complete remission rate of 72% and a 12-month disease-free rate of 57%, respectively. Seminal patents covering intravesical administration of BCG and Anktiva were issued (US 11,173,191 B2 and US 9,925,247 B2) providing term coverage until 2035.

BCG-Unresponsive CIS (QUILT 3.032)

In our Phase 2/3 open-label multi-center trial of BCG-unresponsive high grade NMIBC CIS patients, the patients are receiving BCG plus Anktiva weekly for six consecutive weeks during induction. The patients also receive additional treatment including three weekly maintenance instillations every three months for up to 12 months and then at month 18. Patients with no disease or low-grade Ta disease at months 24, 30, and 36 are eligible for continued BCG plus Anktiva (Cohort A) or Anktiva alone (Cohort C) treatment (3 weekly instillations), at the principal investigators’ discretion. The primary endpoint of the BCG-unresponsive NMIBC CIS trial is a CR rate at any time equal to or greater than 30% and the lower bound of the 95% confidence interval must be greater than or equal to 20% for success. Complete response, or the disappearance of measurable disease in response to treatment, is evaluated at three months or six months following initial administration of Anktiva plus BCG (and every three months thereafter until 24 months). This endpoint would be achieved once at least 24 of the 80 patients in the trial achieve complete response.

All patients enrolled in Cohort A have been treated with the recommended number of full-strength doses of BCG on study during our trial. We have enrolled patients who have received a lower dosage of BCG therapy before enrollment in our trial as a result of BCG shortages. The mean and median number of prior BCG doses in Cohort A is 16.6 and 12.0, respectively, which are consistent with the FDA definition of BCG-unresponsive CIS. The FDA allowed our modification of the study design to allow enrollment of such patients, and definition of these patients may require further discussions with the FDA upon review. A published meta-analysis (Zeng 2015) of six relevant randomized controlled trials and two quasi-randomized controlled trials in NMIBC concluded that low-dose BCG instillation significantly reduces the incidence of overall side effects, especially severe and systemic symptoms in patients with NMIBC, while the oncological control efficacy of low-dose BCG is not inferior to standard-dose BCG. There can be no assurance that the FDA will agree with this conclusion.

A data cutoff occurred in January 2022, which provided a median follow-up in Cohort A in excess of 24 months. Data presented at the ASCO® Genitourinary Cancers Symposium in February 2022 showed a complete response in 59 of 83 patients 71% CR rate (95% CI: 60.1, 80.5) and a median duration of CR of 24.1 months. In those patients who responded to the investigational therapeutic, the probability of avoiding both progression of bladder cancer and cystectomy at 24 months exceeded 90%. The combination of Anktiva and BCG had a well-tolerated profile with 0% treatment-related serious adverse events (SAEs), 0% immune-related AEs, and 100% bladder cancer-specific overall survival at 24 months. Low-grade treatment related AEs include dysuria, hematuria, and pollakiuria (all 16%), urgency (14%), and bladder spasm (8%), all other AEs were seen at 6% or less. No immune-related SAEs have been observed. We continue to engage in discussions with the FDA, and we anticipate filing a BLA for BCG-unresponsive NMIBC CIS in the first quarter of 2022.

BCG-Unresponsive Papillary (QUILT 3.032)

In our Phase 2, open-label multi-center trial of BCG-unresponsive high grade NMIBC papillary patients (Cohort B), the patients are receiving BCG plus Anktiva weekly for six consecutive weeks during induction. The patients also receive additional treatment including three weekly maintenance instillations every three months for up to 12 months and then every nine months for up to 24 months. The primary endpoint of the trial is a 12-month disease free rate greater than or equal to 30% and the lower bound of the 95% confidence interval must be greater than or equal to 20% for success. To meet the primary endpoint, 24 out of 80 patients must be disease free at 12 months.

Data presented at the ASCO® Genitourinary Cancers Symposium in February 2022 showed a 12-month disease-free rate of 57% (95% CI: 44, 68) in the papillary Cohort B, in which 73 of 77 patients (95%) have not progressed to radical cystectomy after a median duration of follow-up of 20.7 months, and a 99% bladder cancer-specific survival through the January 2022 data cutoff.

BCG-Naïve (QUILT 2.005)

As discussed above, Anktiva has been awarded Fast Track designation by the FDA for the treatment of BCG-naïve NMIBC CIS. We are currently enrolling patients in our Phase 2b blinded, randomized, two-cohort, open-label, multi-center trial of intravesical Anktiva plus BCG versus BCG alone, in BCG naïve patients with high-grade NMIBC CIS (Cohort A) and NMIBC papillary (Cohort B). Planned enrollment for Cohort A (CIS) and Cohort B (papillary) is 366 patients and 230 patients, respectively.

2.Lung Cancer (Lung-MAP) (QUILT 2.023)

According to the American Cancer Society, lung cancer is the second most common cancer in the U.S. In 2022, it is estimated that 236,740 new cases of lung cancer will be diagnosed in the U.S. and 130,180 deaths will be attributed to the disease. Non-small cell lung cancer accounts for about 80% to 85% of all lung cancers diagnoses and there are very few successful treatment options for these patients once the cancer spreads beyond the lungs. The development of checkpoint inhibitors in non-small cell lung cancer (NSCLC) has been revolutionary, doubling the median overall survival in some settings; however, patient response may be short lived, due to late response and/or progression after achieving an initial response. As with bladder cancer, Anktiva enhances the proliferation and activation of NK and T cells critical for targeting and killing lung cancer cells. There is therefore a strong rationale to evaluate Anktiva in addition to an anti-PD-1 or anti-PD-L1 checkpoint inhibitor for patients with NSCLC who have relapsed after achieving an initial response to PD-1 or PD-L1 checkpoint inhibitor therapy.

Analysis of the pooled data from a Phase 1/2 trial conducted from January 2016 to June 2017 in 23 patients, and a subsequent investigator-initiated Phase 2 trial conducted by the Medical University of South Carolina, yielded confirmation of activity of the combination of checkpoint inhibitors and Anktiva in relapsed NSCLC. In 15 patients with PD-L1 greater than 50%, the overall response rate was 38% and the median overall survival rate was 17.1 months. These preliminary findings were favorable relative to the historical response rate seen in this patient population in the first-line setting with checkpoint inhibitor therapy.

Table of Contents

On the basis of these findings, we initiated a single-arm Phase 2b multi-cohort basket trial (QUILT 3.055) of Anktiva and checkpoint inhibitor combinations in patients who have previously received treatment with PD-1/PD-L1 immune checkpoint inhibitors per an FDA-approved indication. Patients enrolled in this trial were eligible if actively progressing on checkpoint inhibitor therapy. Upon enrollment, patients continued on the same checkpoint inhibitor but with the addition of Anktiva. Despite progressing on checkpoint inhibitor therapy upon entry into the trial, the majority of patients reverted to stable disease and demonstrated durability of stable disease, some extending as long as nine months. Data presented at the ASCO Annual Meeting in 2021 showed that despite the patients’ prior progression on checkpoint inhibitor therapy alone, upon entry into the trial the majority of patients experienced clinical benefit either as stable disease (49%) or a partial response (9%). Among 133 cancer patients enrolled in QUILT 3.055, the common Anktiva attributed grade 1 and 2 AEs included: injection site reaction (71%), chills (34%), fatigue (27%), pyrexia (24%), flu-like illness (13%), and decreased appetite (10%). A total of 18 grade 3 and 4 AEs attributed to Anktiva have been reported among 16 patients (12%) in the trial as of February 2021. All reported grade 3 and 4 AEs occurred at a frequency of 5% or less; two patients reported increased alanine amino transferase, increased aspartate amino transferase or increased blood alkaline phosphatase, anemia, injection-site reaction or injection-site pain. All other occurrences of grade 3 or 4 AEs that the clinical trial site investigators reported as suspected as being due to Anktiva include: decreased lymphocyte count; weight loss; influenza-like illness; injection site pruritus; cellulitis; injection-site cellulitis; sepsis; deep vein thrombosis; hypovolemic shock; colitis; diarrhea; delirium; respiratory failure; and maculopapular rash.

In October 2021, we announced that Anktiva had been chosen by Lung Cancer Master Protocol (Lung-MAP), a public-private partnership—which includes the NCI, the National Clinical Trials Network (NCTN) Cooperative Groups (SWOG, ECOG-ACRIN, Alliance, and NRG), Friends of Cancer Research, and the Foundation for the National Institutes of Health (FNIH)—to study Anktiva in the Lung-MAP trial. The trial with Anktiva in combination with Keytruda® (pembrolizumab) will include up to 478 second-line patients with tumors that are not targetable with a drug, which accounts for the majority of NSCLC cases. In the fourth quarter of 2021, approval was received from the Institutional Review Board (IRB) overseeing the Lung-MAP study to proceed with the trial—one of the NCI’s largest lung cancer clinical trials with more than 700 sites. Enrollment has begun for this trial.

We are enrolling patients in a randomized Phase 3 trial (QUILT 2.023) to evaluate Anktiva plus checkpoint inhibitor combinations versus other checkpoint inhibitor combinations in the first line setting for NSCLC. Patients will be treated as described below:

•Immunotherapy for either squamous or non-squamous NSCLC with PD-L1 TPS >1% (Cohort A). Combination of Anktiva with Keytruda® versus Keytruda as the standard of care control arm in this randomized trial.

•Chemoimmunotherapy for squamous NSCLC (Cohort B). Combination of Anktiva with Carboplatin, Abraxane® and Keytruda versus Carboplatin, Abraxane / paclitaxel and Keytruda as the standard of care control arm in this randomized trial.

•Chemoimmunotherapy for non-squamous NSCLC (Cohort C). Combination of Anktiva with Cisplatin / Carboplatin, Keytruda and Pemetrexed versus Cisplatin / Carboplatin, Keytruda and Pemetrexed as the standard of care control arm in this randomized trial.

3.Pancreatic Cancer (QUILT 88)

According to the American Society of Clinical Oncology, in the U.S. pancreatic cancer is the fourth leading cause of cancer-related death in both men and women and has one of the highest mortality rates of all major cancers, taking nearly 50,000 lives every year, with a five-year survival rate for late-stage cases of only 3%. Exploratory Phase 1b/2 trials in patients with second-line or greater metastatic pancreatic cancer in which Anktiva and aldoxorubicin were combined with off-the-shelf NK (haNK) cells, other agents, and stereotactic body radiotherapy (SBRT) showed encouraging results in patients with advanced disease. The primary endpoints of the Phase 1b and 2 portions of the trial were safety and objective response rate, respectively. In aggregate, 82% of patients (14/17) with advanced pancreatic cancer achieved disease control following combination therapy including Anktiva and aldoxorubicin. There were no Anktiva-related grade 3 or 4 AEs reported.

On the basis of these exploratory trials, together with the preclinical findings that PD-L1 t-haNK is as active as haNK + anti-PD-L1 mAbs, we initiated a first- through third-line pancreatic cancer clinical trial (QUILT 88) that uses PD-L1 t-haNK as described below.

•First-line advanced pancreatic cancer (Cohort A). Combination of Anktiva with aldoxorubicin and low-dose chemotherapy plus SBRT with or without PD-L1 t-haNK versus gemcitabine/Abraxane® as the standard of care control arm in this randomized trial.

•Second-line advanced pancreatic cancer (Cohort B). Combination of Anktiva with aldoxorubicin and low-dose chemotherapy plus SBRT + PD-L1 t-haNK versus 5FU/Onivyde® as the standard of care control arm in this randomized trial.

•Third-line and beyond (Cohort C). Combination of Anktiva with aldoxorubicin and low-dose chemotherapy plus SBRT + PD-L1 t-haNK in a single arm cohort of this trial with a primary endpoint of overall survival.

On October 13, 2021, we announced that the trial’s Cohort C was fully enrolled. In January 2022 at the ASCO Gastrointestinal Cancer Symposium, we reported that 27% of third-line or greater patients (17/63) remain on study and that the median overall survival in this highly advanced group of patients (who failed two to six prior lines of treatment) is 5.8 months (95% CI: 3.9, 6.9 months) exceeding the approximately three-month historical median overall survival. Of the 63 patients, 30 (48%) had progressed after two prior lines of therapy. Median overall survival in this group was 6.3 months (95% CI: 5.0, 9.8 months), more than doubling the historical overall survival. (Survival of three months as reported by Manax et al ASCO GI 2019). In Cohort C, four patients (7%) experienced treatment-related SAEs that included peripheral edema, pyrexia, anemia and atrial flutter. No treatment-related deaths were reported.

Based on the strength of earlier data and the significant unmet medical need, we submitted an amendment to the FDA to increase enrollment in Cohort C and plan to meet with the FDA in 2022 to discuss a potential path for the approval of combination therapies for pancreatic cancer.

4.Triple-Negative Breast Cancer (QUILT 3.058)

According to the Breast Cancer Research Foundation, globally more than 2.3 million women were diagnosed with breast cancer in 2020 and 685,000 died from it. Triple-negative breast cancer is especially aggressive and accounts for 10-15% of breast cancers according to the American Cancer Society. In a prior exploratory Phase 1b/2 trial (QUILT 3.067), which included nine heavily pre-treated metastatic TNBC patients, we treated them with a combination immunotherapy that included Anktiva and aldoxorubicin, haNK cell therapy, along with several other immunotherapy agents. The primary endpoints of the Phase 1b and 2 portions of the trial were safety and objective response rate, respectively. The exploratory Phase 1b/2 trial in nine patients with advanced TNBC showed a disease control rate of 89% with a complete or partial response of 67% (6/9), including two patients (22%) with a complete response to the combination therapy. The median progression-free survival was 14.3 months with median overall survival of 20.2 months as of December 2020. Eight of the nine patients had primarily chemotherapy-related neutropenia or anemia, but all cases were low grade. A total of 27 grade 3 AEs were reported by 9 patients (100%) and included disease progression, pyrexia, mastitis, pneumonia, nausea, cholecystitis, and pain in extremity. However, none of these SEAs were attributed to Anktiva. There were three grade 3 haNK-related AEs with fever and fatigue, but no patient withdrew due to an SAE or experienced cytokine release syndrome.

Table of Contents

Based on this encouraging data, in June 2021 we announced we had received FDA authorization to conduct a Phase 1b/2 open-label study to evaluate the safety and preliminary efficacy of Anktiva and PD-L1 t-haNK cells in combination with standard chemotherapy and Trodelvy® (sacituzumab govitecan-hziy) in patients with advanced TNBC. The study consists of two phases and will enroll up to 79 patients. The Phase 1b portion of the study has 2 parts: Part 1 involves dose escalation using a 3+3 design, and Part 2 involves the expansion of the recommended Phase 2 dose (RP2D) to further evaluate the safety and efficacy of sacituzumab govitecan-hziy plus chemoimmunotherapy. The Phase 2 portion of the study is based on a Simon’s two-stage optimal design. In Phases 1b and 2, all patients receive sacituzumab govitecan-hziy plus chemotherapy combined with immunotherapy: cyclophosphamide, Anktiva, and PD-L1 t-haNK on a 3-week schedule. The dose of sacituzumab govitecan-hziy is dependent on dose level cohort for Phase 1b and will be set at the RP2D for Phase 2. The doses of cyclophosphamide, Anktiva, and PD‑L1 t-haNK will remain the same in all dose level cohorts and phases. This trial is open and currently enrolling patients.

5.Glioblastoma Mulitforme (QUILT 3.078)

According to the American Association of Neurological Surgeons, GBM is the most common malignant brain and other tumors accounting for approximately 48% of all primary brain tumors with a low survival rate of approximately 40% in the first year after diagnosis and only 17% in the second year. A single arm Phase 2 trial was completed in 2016 that assessed the preliminary efficacy and safety of aldoxorubicin administered to recurrent GBM patients who progressed after first-line therapy. The primary endpoint of the trial was objective response rate. Out of 28 patients, investigator assessment of best overall tumor response reported three patients with a partial response, seven patients with progressive disease, and 11 patients with stable disease. Treatment-related grade 3 or 4 AEs included: neutropenia, thrombocytopenia, febrile neutropenia, and lymphopenia.

A new randomized, multi-center, Phase 2 trial is currently being developed to evaluate the efficacy and safety of the combinations of Anktiva, aldoxorubicin, PD-L1 t-haNK and bevacizumab in this indication. A pilot phase will evaluate different combinations of triplets and the quadruplet, and a winner will be selected for the randomized portion versus bevacizumab monotherapy as the current standard of care for relapsed/refractory (r/r) GBM. We plan to begin enrollment of this trial in 2022.

6.Human Papillomavirus-Associated Tumors (Cervical and Head & Neck)

According to the Centers for Disease Control and Prevention, every year about 19,400 women and 12,100 men experience cancers caused by the human papillomavirus (HPV), which is the most common sexually transmitted infection in the U.S. According to the NCI, head and neck cancers account for nearly 4% of all cancers in the U.S. It was estimated that more than 68,000 men and women in the U.S. would be diagnosed with head and neck cancers in 2021. IBRX-042 leverages our hAd5-based vaccine platform to target tumors caused by HPV infection, which includes most types of cervical cancer and some types of head/neck cancers. Our second-generation hAd5 vector includes enhancements with the E1, E2b, E3 regions of the hAd5 deleted (E1-, E2b-, E3-), decreasing the risk for vector-directed immune responses that may reduce efficacy, while maintaining high target antigen production. The platform has previously been used to generate vaccines against tumor-associated antigens such as MUC1 and Brachyury. In IBRX-042, hAd5 encodes HPV-16 E6 and E7 tumor-associated proteins (oncotarget antigens). E6 and E7 play a role in early infection and, importantly, transformation of cells into rapidly-dividing tumor cells. Specifically, E6 promotes degradation of p53—a factor that typically prevents excess cell division—indirectly activates telomerase, and disrupts the function of the cellular phosphatase tumor suppressor PTPN13. E7 inactivates pRb (which plays a role similar to the p53) and activates Mi2b and is also implicated in transformation. Together, these oncogenic alterations drive rapid cellular proliferation, suppress or downregulate key tumor suppressor proteins, and lead to cellular immortality. In addition, E6 and E7 expression is required to maintain a malignant transformed phenotype. IBRX-042 has demonstrated the ability to induce immune responses against HPV16 antigens that induced significant anti-tumor effects in vivo in HPV+ mouse models. To support clinical studies, we have successfully completed the GMP production of GMP IBRX-042.

We are planning a Phase 1/2 open-label trial to evaluate the safety and efficacy of subcutaneous (SC) IBRX-042 vaccination combined with Anktiva (to enhance immune responses) and PD-L1 t-haNK cells in patients with HPV-associated tumors. We intend to add Anktiva to evaluate the safety and efficacy of the combination followed by PD-L1 t-haNK. We plan to begin enrollment of this trial in 2022.

7.Solid Tumor (QUILT 3.076)

An initial clinical trial showed that healthy and patient-derived M-ceNK cells killed NK-resistant tumor cells. We initiated a Phase 1 study of cryopreserved M-ceNK cells in combination with Anktiva to evaluate safety in subjects with locally advanced or metastatic solid tumors. The study will compare the quantity and quality of the M-ceNK cells collected and manufactured from newly diagnosed patients who have not received prior treatment to the M-ceNK cells collected and manufactured from patients who have received at least two prior treatments for their cancer. The study consists of two cohorts and there will be 10 participants in each cohort. Cohort 1 includes participants with newly diagnosed high-risk solid tumors who have not received prior treatment; and Cohort 2 includes participants with r/r solid tumors who have progressive disease after receiving at least two prior therapies. Participants will be enrolled in the two cohorts simultaneously. Participants in Cohort 1 will participate in apheresis collection of lymphocytes (part A) and will not receive any investigational therapy in this study. Participants in Cohort 2 will undergo an apheresis collection of lymphocytes (part A) prior to receiving approximately four weeks of disease-specific therapy per their oncologists’ recommendations.

8.Non-Hodgkin’s Lymphoma

According to the American Cancer Society, in 2022 it is estimated that 80,470 new cases of non-Hodgkin’s lymphoma (NHL) will be diagnosed in the U.S., and 20,250 deaths will be attributed to the disease. A Phase 1 trial evaluating Anktiva in combination with rituximab, an anti-CD20 mAb therapy, in patients with indolent non-Hodgkin’s lymphoma (iNHL), who had relapsed or were refractory after two lines of therapy, was published in the American Association for Cancer Research journal, Clinical Cancer Research, in 2021. The combination regimen of Anktiva and Rituxan® was well tolerated with a single reported grade 4 AE and no reported grade 5 AEs. For patients with anti-CD20 mAb sensitive disease, the ORR in the SQ cohort was 78% (7 of 9) with 7 of 7 (100%) responses in the SQ cohorts were complete remissions (CRs).

Most B-cell malignancies express high levels of CD19, including the majority of NHLs, such as diffuse large B Cell lymphoma (DLBCL), follicular lymphoma (FL), and mantle cell lymphoma. In addition, many leukemias express high levels of CD19, including B-cell precursor acute lymphoblastic leukemia, chronic lymphocytic leukemia (CLL), and hairy cell leukemia. As such, two CD19‑directed CAR-T cell therapeutics are FDA-approved for use in a variety of indications including NHL and ALL. Like T cells, NK cells can be genetically modified to express CARs that recognize tumor‑associated cell-surface antigens and mediate specific recognition and lysis of cancer cells. A number of aNK cell lines that express CARs have been developed and importantly, aNK cells engineered with CARs targeting CD19 and CD20 have shown to be effective against in vitro/in vivo models of lymphoblastic leukemia and lymphoma (Boissel 2013, Muller 2008, Romanski 2016). Derived from aNK, the haNK cell line is engineered to express the high-affinity variant of the Fcγ receptor (FcγRIIIa/CD16a 158V) as well as endoplasmic reticulum-retained IL-2, and has demonstrated enhanced ADCC-mediated antitumor activity (Jochems 2016). The CD19 t-haNK cell line combines the engineered enhancements of haNK cells with the expression of a CAR targeting CD19, and thus has potential to demonstrate robust ADCC antitumor activity against cancerous B cells and provide clinical benefit to patients with r/r NHL. We are currently developing an open-label, Phase 1 trial of CD19 t-haNK as a single agent and in combination with Anktiva and rituximab in patients with r/r NHL.

In addition to the studies listed above, we are pursuing several other both company-sponsored and investigator-initiated studies of our product candidates including in colon cancer (hAd5 CEA), Kaposi’s sarcoma (aldoxorubicin), and head and neck cancer (Anktiva, hAd5 CEA, MUC1, and Brachyury) among others.

COVID-19 Programs

In order to address the ever-evolving COVID-19 pandemic, several key findings have emerged through intense research activity since the virus was first identified. We believe these findings include the need for second-generation COVID-19 vaccines with cross-reactive memory B and T cells in the face of antigenic drift and a heterologous prime/boost approach without cold chain limitations. Vaccines against SARS-CoV-2 were developed with exceptional speed and initially showed a high degree of efficacy against the wild-type virus, with RNA vaccines showing the highest degree of efficacy and a sound safety profile. However, in the time since their authorization, we believe that a number of important limitations have been recognized. First, these vaccines have required boosting for increased efficacy. Second, their availability in the low income global community has been limited. Third, they have shown reduced efficacy against emergent variants of concern (VOC). Fourth, they exhibit heat-sensitivity and require a cold chain that may be infeasible in many low-resource settings. Researchers aim to address these limitations and have recently made several relevant advances. For example, second-generation COVID-19 vaccines with DNA and RNA delivery platforms that are heat-stable, potent and broadly protective against multiple VOC have been developed and are in clinical trials. Additionally, vaccines which stimulate the innate immune system through the TLR system invoke strong and broad humoral and cellular responses. We believe that T cell immunity plays a central role in the control of SARS-CoV-2 and its importance may have been relatively underestimated thus far. Our COVID-19 vaccine product candidates are designed to provide second-generation T cell as well as antibody-based protection.

a.Spike in Combination with Nucleocapsid

Since the inception of the pandemic, we have hypothesized that antibody-based vaccines, specifically those that target the S protein alone, would prove insufficient over an extended time period to prevent transmission and infectivity due to their inability to overcome viral evolution in the face of a rapidly mutating S protein on the SARS-CoV-2 virus. In fact, what has been observed over the past year is that anti-S antibody levels and immune protection against COVID-19 subsides following vaccination with currently available S targeting vaccines, requiring booster shots at approximately six months. Compounding the limitations of an S-only approach is the spike protein is under intense immune pressure from vaccine-induced antibodies, which drives the evolution of vaccine escape variants. Internal proteins of the SARS-CoV-2 virus, such as the N protein, are more highly conserved and less subject to mutation and thus may be more appropriate targets to maintain vaccine efficacy in the face of this viral evolution.

Table of Contents

From the onset, we believed strongly that an immune response generating a combination of antibodies, T cells, and memory B cells is critical to prevent infection, reduce viral load, prevent transmission, provide durable protection and ultimately overcome this pandemic. Therefore, we focused our efforts on developing vaccine candidates with an S-Fusion + N-ETSD that express both an optimized viral spike (S) protein (S-Fusion) and a nucleocapsid protein with an Enhanced T-cell Stimulation Domain (N-ETSD) that directs N to the endo/lysosomal subcellular compartment to enhance MHC Class II responses. In order to reduce viral load, T cells are necessary to kill virally-infected cells in the nasal and lung passages and thereby prevent transmission even from highly transmissible variants. We performed a non-human primate COVID virus challenge study in September 2020 (supported by BARDA and published in September 2021 in Frontiers in Immunology entitled, “Dual-Antigen COVID-19 Vaccine Subcutaneous Prime Delivery with Oral Boosts Protects NHP Against SARS-CoV-2 Challenge”) confirming that our second-generation adenovirus hAd5 S+N vaccine accomplished the goal of reducing viral load to non-detectable levels following a COVID-19 virus challenge.

On the basis of these findings, a program was designed to pursue this strategy of driving T cell and antibody protection, and to develop a second-generation vaccine with broad depth of antigenic coverage. The initial study, which began in March 2020, showed that hAd5 S+N vaccination as a single prime alone induced a 10-fold increase in mean T cell responses in Phase 1 participants that were sustained against spike variants.

b.Heterologous Prime Boost

Moreover, since initiating the initial homologous prime boost trial in the U.S., it has become apparent that a “mix-and-match” strategy (i.e., a heterologous approach combining different vaccine platforms) could potentially provide maximal immune protection against current and future variants such as Delta and Omicron. For example a “Prime” with an RNA vaccine leads to strong antibody response while a “Boost” with a DNA or an EDV/adjuvant vaccine could convey strong cellular immune responses. On this basis we have acquired the rights to multiple platforms and initiated a consortium that includes 3M, Amyris, BCM, EnGeneIC and IDRI to develop, manufacture and scale second-generation vaccines that combine different advanced DNA, RNA, protein constructs, and adjuvants. We have adopted a long-term approach to addressing COVID-19 and future pandemics and believe these mix-and-match components are critical to providing accessible, broad, and durable protection. Importantly we believe that the technologies behind these heterologous approaches are not burdened by the limitations of first-generation RNA cold-chain requirements.

1.hAd5 S+N Platform Prime & Boost—U.S. (COVID 4.001 and 4.005) and South Africa COVID (4.007)

In October 2020, the FDA authorized a Phase 1 trial of our dual construct Spike+Nucleocapsid (hAd5 S+N) COVID-19 vaccine, designed to drive both T cell and antibody immunity. We undertook a rigorous development strategy to explore multiple methods of administration (oral, intranasal, subcutaneous, and combinations of each) to determine the best site of delivery to achieve maximum antibody, T cell and mucosal immunity. In February 2021, this trial was expanded to South Africa (the ProVIVA-SA1 Trial). Through the date of this Annual Report, 114 participants have enrolled in the U.S. and South African Phase 1 trials. Data acquisition and analysis from both trials is ongoing. Preliminary analysis has shown that subcutaneous dosing of hAd5 S+N provides strong T-cell responses to both Spike and Nucleocapsid antigens with no SAEs reported through the date of this Annual Report. These trials formed the basis of the Universal T Cell Boost Trial (SISONKE Boost Trial) activated in South Africa in July 2021.

2.SISONKE Boost Trial—South Africa (COVID 4.010)

In July 2021 we announced authorization from the South African Health Products Regulatory Authority (SAHPRA) to proceed with our SISONKE T-Cell Universal Boost trial in South Africa. This Phase 1/2/3 trial was the first DNA/DNA heterologous mix-and-match trial of Ad26 and hAd5 and was designed to study the efficacy, safety, and immunogenicity of ImmunityBio’s T-Cell COVID-19 vaccine as a boost in participants who had already received a spike-only antibody-based vaccine. The trial is designed to explore whether the T cell-based vaccine could prevent breakthrough infections from the Delta variant in health care workers who are already vaccinated. The goal of the hAd5 S+N vaccine is to potentially provide increased protection and long-term immunity against the multiple variants and multiple waves affecting South Africa and other countries. The SISONKE Universal Boost Phase 2 trial is fully enrolled with 60 participants with no SAEs reported through the date of this report. The Phase 3 trial is now open and enrollment began in January 2022.

3.THEMBA saRNA Vaccine Boost—South Africa (COVID 4.015) and U.S. (COVID 4.016)

The THEMBA trials are the first studies of our saRNA with next-generation NLCs. In South Africa, we initiated the filing of a Phase 1/2 trial assessing the safety, reactogenicity, and immunogenicity of saRNA-based vaccines against SARS-CoV-2 as boost vaccines in participants that have been previously vaccinated against or previously infected with COVID-19, which is under regulatory review at the SAHPRA awaiting authorization to begin. In the U.S., we submitted a similar Phase 1/2 trial design for FDA review in the first quarter of 2022. The Phase 1 trial, for up to 60 previously vaccinated/infected participants will be enrolled as 6 separate cohorts to receive a single vaccine boost consisting of different doses of either saRNA encoding the Spike protein (AAHI-SC2 vaccine) or saRNA encoding the Spike and nucleocapsid proteins (AAHI-SC3 vaccine) delivered by NLC. The Phase 2 trial, of up to 120 previously vaccinated/infected additional participants, will be enrolled with a randomized 1:1:1:1 design to receive Janssen, Moderna or Pfizer-BioNTech vaccines (control arm), the AAHI-SC2 vaccine (experimental arm 1), or the AHHI-SC3 (experimental arms 2 and 3).

4.PULA Trial RBD Subunit Protein with TLR Adjuvant Boost—Botswana (COVID 4.014)

We plan on submitting a Phase 1/2/3 trial assessing the safety, reactogenicity, and immunogenicity of a yeast-based COVID-19 vaccine with a TLR activating adjuvant to the Botswana Medical Research Authority (BOMRA) to be called PULA. In November 2021, we announced we had licensed a recombinant protein COVID-19 vaccine (RBD Subunit) candidate from BCM. Protein-based vaccines have long been used to confer immunity against hepatitis B and HPV, as immune responses often target proteins that are part of viruses and bacteria. This recombinant protein vaccine technology is proven and well-established. Production of these vaccines can be easily scaled up in low-resource countries. We are combining this subunit protein with a 3M-052/Alum adjuvant and related technology licensed from IDRI and 3M Company and its affiliates in this PULA trial.

HIV

In June 2021, we announced the opening of a Phase 1 “HIV Cure Study” in patients on therapy and a Phase 2 study in acutely infected patients. Both studies have opened and are actively enrolling participants.

1.HIV Cure Study

Sponsored by the NIAID and AIDS Clinical Trials Group, the “HIV Cure Study” will evaluate whether Anktiva alone or together with broadly neutralizing antibodies can control HIV following interruption of antiretroviral therapy (ART). The Phase 1 open-label, randomized trial will enroll 46 people living with HIV whose virus has been suppressed by ART for approximately two years, including at least 30% cisgender women or transgender men.

2.Thai Red Cross and the US Military HIV Research Program

An additional Phase 2 trial, enrolling 15 patients, has been initiated with the Thai Red Cross and the U.S. Military HIV Research Program. The trial is designed to investigate the safety, tolerability and immunostimulatory effects of administering Anktiva during acute HIV infection. Anktiva will be administered subcutaneously at weeks zero, three and six (for a total of three doses) and will be initiated together with antiretroviral therapy in order to determine if the immunostimulatory effects of Anktiva will reduce the amount of HIV present during acute infection. The trial duration for individual participants will be approximately 12 weeks. It is hypothesized that Anktiva initiated with anti-retroviral therapy during acute HIV infection will not result in complications or additional toxicities compared with anti-retroviral therapy alone, and may result in a reduced viral load in these patients by inhibiting early establishment of HIV reservoirs in infected individuals.

3.NIAID University of Minnesota Trial

An ongoing Phase 1b, non-randomized, open label clinical trial sponsored by the University of Minnesota in collaboration with the National Institute of Allergy and Infectious Diseases (NIAID) is investigating the effect of Anktiva on B cell follicles in antiretroviral treated HIV disease. This trial includes 10 HIV-infected adults on effective antiretroviral therapy who will receive Anktiva to intensively investigate the immunological effects of treatment. The hypothesis is that in HIV infected humans treated with Anktiva, CD8 T cells will migrate to and increase in number in B cell follicles that will result in a reduction in the frequency of cells with an inducible HIV provirus. The trial is fully enrolled, and there are currently 2 active patients on study as of this date of this report.

Our Large-Scale GMP Biologic Manufacturing Capabilities

ImmunityBio has adopted a strategic position to be vertically integrated and develop its products according to the FDA’s GMP standards for large-scale manufacturing, even during Phase 2 clinical trial development. Biological upstream and downstream manufacturing capabilities, with its attendant know-how and regulatory compliance for approval, have long lead times. We have adopted an approach for preparedness to provide our vaccine, immunotherapy and cell therapy products at a global scale. As such, we have established our own plants and have access to facilities on a global basis.

Our ability to create an efficient manufacturing process and supply chain will be important in enabling us to develop novel therapies. Our strategy is to anticipate the needs of our early-stage research and development initiatives for preclinical and eventual clinical product candidates with a focus on rapid capability to produce at scale fusion proteins, hAd5, saRNA, subunit protein, EDV, and NK cell products. In addition, our pipeline for development of synthetic small molecules and immunomodulatory peptides uses innovative technology to derive new therapies. We believe members of our management team, many of whom have experience in both nanoparticle commercialization and large-scale injectable drug production, are capable of constructing the processes and commissioning the facilities necessary to meet our development and commercialization goals. For well-known processes, we currently work, and plan to continue working, with established contract manufacturing organizations (CMOs) to produce drug substance and drug products. In addition, we plan to further enhance our in-house manufacturing capabilities for drug substances, drug products, and labeling and packaging.

Overview of our Manufacturing Model

Our manufacturing capabilities include advanced technology facilities to produce and test various drug substances and drug products. Our experienced operations and quality team focuses on internal manufacturing and testing with a constant endeavor to create robust, high quality, efficient and consistent supply that meets target product profiles. Our Phase 1 manufacturing process is designed to seamlessly scale-up through all phases of clinical development to commercial manufacturing to drive successful commercialization.

Commercial cGMP Production

For our Anktiva product candidate, we have contracted with a multi-national biologics manufacturer with multiple cGMP-compliant facilities in the U.S., Europe and Asia for our current clinical trials and future commercial sales, if approved. The facilities have robust process development and validation and quality oversight with high-capacity production suites operating multiple 2,000-20,000L production bioreactors.

Clinical Trial GMP Antibody and Fusion Protein Production

We are establishing a cGMP-compliant multi-platform facility in California, which includes a large space for the production of antibodies and fusion proteins (including Anktiva) to treat cancers and infectious diseases. This facility will include fully integrated biologic upstream and downstream production suites and a quality assurance/quality control release laboratory for high-capacity antibody and fusion protein production.

Table of Contents

Clinical Trial GMP saRNA, Adenovirus, and Yeast Production

We have established other cGMP-compliant facilities for saRNA, adenovirus, and yeast production in multiple sites in California and a site in Colorado for oncology and infectious diseases. One of our sites in California is dedicated to adenovirus product candidates for the production of vaccine candidates to treat infectious diseases. These facilities generally have fully-integrated biologic upstream and downstream production suites and quality assurance/quality control release laboratories for high capacity, continuous, or personalized just-in-time vaccine production.

Clinical Trial GMP NK Cell Therapy Production

We have established other cGMP-compliant facilities for NK cell therapy product production in multiple sites in California for oncology. One of our sites in California is dedicated to our off-the-shelf product candidates (including PD-L1 t‑haNK), while another is primarily focused on our M-ceNK product candidates, including a training lab for our second-generation offerings.

cGMP ISO Class 5 Manufacturing Facility

On February 14, 2022, we acquired a leasehold interest in approximately 409,000 rentable square feet of cGMP ISO Class 5 pharmaceutical manufacturing space in western New York (the Dunkirk Facility). This facility provides us with a state-of-the-art biotech production center that substantially expands and diversifies our existing manufacturing capacity in the U.S. and will be used across all of our key platforms. See Note 13, Subsequent Events, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for additional information.

Manufacture of Platform Product Candidates

ImmunityBio’s diverse product candidate portfolio and pipeline requires a broad knowledge of various manufacturing and quality assurance methods. We have invested heavily in the processes, systems and technology to build an extensive range of manufacturing programs spanning various levels of development from IND-enablement through BLA preparation of our first commercial product.

We believe our plan to selectively use CMOs for certain of our assets at various stages, coupled with internal development, will give us assurance that any products will have backup manufacturing options.

Competition

We face potential competition from many different sources, including major and specialty pharmaceutical and biotechnology companies, academic research institutions, governmental agencies and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with current therapies and new therapies that may become available in the future. We believe that the key competitive factors affecting the success of any of our product candidates will include efficacy, safety profile, convenience, cost, market access, level of promotional activity devoted to them, competitive intensity, and intellectual property protection.

We have focused our efforts on oncological and infectious disease indications that are difficult to treat and with large unmet needs, and we believe our platform will be broadly applicable across multiple tumor types and infections. Based on the breadth and depth of our platforms, we believe our competitors will range from large pharmaceutical companies to emerging novel biotechnology companies.

Oncology

•Antibody Cytokine Fusion Proteins. This platform primarily competes with large pharmaceutical companies marketing checkpoint inhibitors. However, the potential exists for some of these large pharmaceutical companies to seek collaboration for combination of Anktiva with their marketed checkpoint inhibitor.

In addition, a very large number of companies, government agencies and academic centers around the world are developing COVID-19 vaccines and therapeutics. In the HIV space, we have product candidates that use Anktiva that will likely compete with companies who have approved therapeutics for HIV, including Abbott Laboratories Inc., BMS, Gilead, and GSK.

Intellectual Property

We strive to protect and enhance the proprietary technology, inventions, and improvements that are commercially important to our business, including seeking, maintaining, and defending patent rights, whether developed internally or licensed from third parties. Our policy is to seek to protect our proprietary position by, among other methods, filing patent applications in the U.S. and in jurisdictions outside of the U.S. related to our proprietary technology, inventions, improvements, and product candidates that are important to the development and implementation of our business. We also rely on trade secrets and know-how relating to our proprietary technology and product candidates, continuing innovation, and in-licensing opportunities to develop, strengthen, and maintain our proprietary position in the field of cancer therapeutics and immunotherapy. We expect to rely on data exclusivity, market exclusivity, patent term adjustment and patent term extensions when available, as well as on regulatory protection afforded through orphan drug designations. Our commercial success will depend in part on our ability to obtain and maintain patent and other proprietary protection for our product candidates, technology, inventions, and improvements; to preserve the confidentiality of our trade secrets; to maintain our licenses to use intellectual property owned by third parties; to defend and enforce our proprietary rights, including our patents; and to operate without infringing, misappropriating or otherwise violating the valid and enforceable patents and other proprietary rights of third parties.

Table of Contents

The term of individual patents extend for varying periods of time, depending upon the date of filing of the patent application, the date of patent issuance, and the legal term of patents in the countries in which they are obtained. Generally, patents issued for applications filed in the U.S. are effective for 20 years from the earliest effective filing date of a non-provisional patent application. The patent term may be adjusted to compensate for delayed patent issuance, when such delays are caused by the United States Patent and Trademark Office (USPTO) or successful appeals against USPTO actions. There is no statutory limit on this patent term adjustment, which is generally the length of any such delays caused by the USPTO. In addition, in certain instances, a patent term can be extended to recapture a portion of the term effectively lost as a result of the FDA regulatory review period. The restoration period cannot be longer than five years, the total patent term, including the restoration period, must not exceed 14 years following FDA approval, only one patent applicable to an approved drug may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. While we plan to seek such patent term adjustments and extensions where applicable, there is no guarantee that the USPTO and/or FDA will agree with our assessment of whether such adjustments or extensions should be granted, and if granted, the length of such adjustments or extensions. The duration of patents outside of the U.S. varies in accordance with provisions of applicable local law, but typically is also 20 years from the earliest effective filing date. However, the actual protection afforded by a patent varies on a product-by-product and country-to-country basis and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory-related extensions, the availability of legal remedies in a particular country, and the validity and enforceability of the patent.

The patent positions of companies like ours are generally uncertain and involve complex legal and factual questions. No consistent policy regarding the scope of claims allowable in patents in the field of immunotherapy has emerged in the U.S. The patent situation outside of the U.S. is even more uncertain. Changes in either the patent laws or their interpretation in the U.S. and other countries may diminish our ability to protect our inventions and enforce our intellectual property rights, and more generally could affect the value of our intellectual property. In particular, our ability to stop third parties from making, using, selling, offering to sell, or importing products that infringe our intellectual property will depend in part on our success in obtaining and enforcing patent claims that cover our technology, inventions, and improvements. With respect to both licensed and owned intellectual property, we cannot be sure that patents will be granted with respect to any current pending patent applications or with respect to any patent applications filed in the future, nor can we be sure that any existing patents or any patents that may be granted in the future will be commercially useful in protecting our product candidates and the methods used to manufacture those product candidates. Moreover, even our issued patents do not guarantee us the right to practice our technology in relation to the commercialization of our product candidates. The area of patent and other intellectual property rights in biotechnology is an evolving one with many risks and uncertainties, and third parties may have blocking patents that could be used to prevent us from commercializing our product candidates and practicing our technology. Our issued patents and those that may issue in the future may be challenged, invalidated, or circumvented, which could limit our ability to stop competitors from marketing related products or limit the length of the term of patent protection that we may have for our product candidates. In addition, the rights granted under any issued patents may not provide us with protection or competitive advantages against competitors with similar technology. Furthermore, our competitors may independently develop similar technologies. For these reasons, we may have competition for our product candidates. Moreover, because of the extensive time required for development, testing and regulatory review of a potential product candidate, it is possible that, before any particular product candidate can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of the patent.

Our registered trademark portfolio currently contains approximately 9 registered trademarks in the U.S., approximately 25 registered trademarks in foreign jurisdictions, approximately 7 pending trademark applications in the U.S., and approximately 11 pending trademark applications in foreign jurisdictions. We may also rely, in some circumstances, on trade secrets to protect our technology. However, trade secrets are difficult to protect. We seek to protect our trade secrets and other proprietary information, in part, by entering into confidentiality agreements with those who have access to our confidential information, including our employees, contractors, consultants, collaborators, and advisors. We also seek to preserve the integrity and confidentiality of our proprietary technology and processes by maintaining physical security of our premises and physical and electronic security of our information technology systems. Although we have confidence in these individuals, organizations, and systems, agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets may otherwise become known or may be independently discovered by competitors. To the extent that our employees, contractors, consultants, collaborators, or advisors use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions. For risks related to our proprietary technology, inventions, improvements and products, see Part I, Item 1A., “Risk Factors—Risks Related to Intellectual Property” and Item 3., “Legal Proceedings” of this Annual Report.

Altor has the first right to enforce the patents licensed pursuant to the agreement, subject to Beike’s ability to exercise such right if Altor fails to do so. Altor and Beike each have the right to terminate the agreement in the event of a material breach by the other party.

Sorrento Therapeutics, Inc.

In 2015, we and Sorrento established NANTibody as a stand-alone biotechnology company with $100.0 million in initial joint funding. We own 60% of the equity interests and Sorrento owns 40% of the equity interests in NANTibody, which focuses on accelerating the development of multiple therapeutic product candidates that are being developed as standalone treatments as well as in combination with other therapies as part of an immune-oncology treatment regimen.

In 2015, we entered into an exclusive license agreement with Sorrento pursuant to which we obtained an exclusive license under certain patent rights and antibody materials, including antibody sequences and complementary DNA (cDNA) and clones and a non-exclusive license under certain know-how, in each case to use, research and develop certain antibodies and anti-body drug conjugates (ADCs) including for neoepitopes, which are epitopes resulting from mutations specific to an individual’s cancer cells, and to commercialize the resulting licensed products, in exchange for consideration that included an upfront cash payment of $10 million, equity consideration with a valuation of $100 million, and mid-single digit percentage royalties on net sales of the resulting licensed products. Our obligation to pay royalties continues, on a licensed product-by-licensed product and country-by-country basis, until the later of (i) the date on which such licensed product is no longer covered by a valid claim of a patent licensed pursuant to the agreement in such country and (ii) ten years after the first commercial sale of such licensed product in such country. In addition, the agreement provides us with the right to negotiate an exclusive license from Sorrento for two CAR-T/NK cell products to be mutually determined on terms substantially similar to the terms of the license agreement.

We must use commercially reasonable efforts to develop and commercialize the licensed products. Subject, as applicable, to the licenses granted by Sorrento to us, each party shall own all inventions and other developments it creates or develops in the course of activities conducted pursuant to the agreement. Sorrento has the first right to prosecute, maintain, defend and enforce the patents licensed pursuant to the agreement, subject to our ability to exercise such rights if Sorrento fails to do so. We may terminate the agreement, in our sole discretion, in whole or on a product-by-product and country-by-country basis, at any time upon 60 days’ prior written notice to Sorrento. In addition, either party may terminate the agreement in the event of a material breach by the other party.

In 2015, NANTibody entered into an exclusive license agreement with Sorrento pursuant to which NANTibody obtained a royalty-free exclusive license under certain patent rights and materials, including antibody sequences and cDNA, and clones and a non-exclusive license under certain know-how, in each case related to up to 75 immuno-oncology antibodies, immune-check point antibodies, bi-specific antibodies and/or ADCs from Sorrento’s G-MAB library to be mutually identified by the parties (21 of which were already identified at the time of signing the agreement), to use, research, develop and commercialize the resulting licensed products. NANTibody must use commercially reasonable efforts to develop and commercialize the licensed products. Subject, as applicable, to the licenses granted by Sorrento to NANTibody, each party shall own all inventions and other developments it creates or develops in the course of activities conducted pursuant to the agreement. Sorrento has the first right to prosecute, maintain and defend the patents licensed pursuant to the agreement, subject to NANTibody’s ability to exercise such rights if Sorrento fails to do so. NANTibody has the first right to enforce antibody-specific patents and Sorrento has the first right to enforce the other patents licensed pursuant to the agreement. NANTibody may terminate the agreement, in its sole discretion, in whole or on a product-by-product and country-by-country basis, at any time upon 90 days’ prior written notice to Sorrento. In addition, either party may terminate the agreement in the event of a material breach by the other party.

In 2019, we filed cross-claims against Sorrento in the Superior Court of California, Los Angeles County, alleging that Sorrento breached the exclusive license agreement with us; these claims are now being pursued in arbitration. In January 2020 and April 2020, Sorrento sent letters purporting to terminate the exclusive license agreement with us and the exclusive license agreement with NANTibody. We believe we have cured any perceived breaches during the 90-day contractual cure period provided under the agreements. Sorrento filed counterclaims against the company and NANTibody in the arbitration and requested leave to file a dispositive motion. The hearings in the NANTibody arbitration commenced in April 2021 and concluded in early August 2021. After post-hearing briefing was concluded, the parties were notified on November 30, 2021 that the arbitrator in the NANTibody arbitration had passed away. A substitute arbitrator was appointed on February 25, 2022, and the parties will work with the substitute arbitrator to conclude the proceedings. For more information, see Note 7, Commitments and Contingencies—Sorrento Therapeutics, Inc. Litigation, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

Government Regulation

In the U.S., the FDA regulates biopharmaceuticals under the Food, Drug and Cosmetic Act (FDCA) and the Public Health Service Act (PHSA). Biopharmaceuticals also are subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent 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 U.S. requirements at any time during the product development process, approval process or post-market may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, untitled or warning letters, product recalls or market withdrawals, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement and civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. Failure to comply with statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including warning letters, the seizure or recall of products, injunctions, consent decrees placing significant restrictions on or suspending manufacturing operations and civil and criminal penalties. Contract manufacturers often encounter difficulties involving production yields, quality control and quality assurance, as well as shortages of qualified personnel. Any of these actions or events could have a material impact on the availability of our product candidates.

The FDA and other regulatory authorities at federal, state, and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring, and post-approval reporting of biologics such as those we are developing. We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources.

The process required by the FDA before biopharmaceutical product candidates may be marketed in the U.S. generally involves the following:

•completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s GLP requirements;

•submission to the FDA of an IND, which must become effective before clinical trials may begin and must be updated annually or when significant changes are made;

•approval by an independent IRB or ethics committee for each clinical site before the clinical trial is begun;

•performance of adequate and well-controlled human clinical trials to establish the safety, purity and potency of the proposed biologic product candidate for its intended purpose;

•preparation of and submission to the FDA of a BLA or NDA, after completion of all required clinical trials;

•a determination by the FDA within 60 days of its receipt of a BLA/NDA to file the application for review;

•satisfactory completion of an FDA Advisory Committee review, if applicable;

•satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is produced to assess compliance with cGMP and to assure that the facilities, methods and controls are adequate to preserve the product candidates’ continued safety, quality, purity and potency or efficacy, and of selected clinical investigational sites to assess compliance with GCP requirements;

•FDA review and approval of the BLA or NDA to permit commercial marketing of the product for particular indications for use in the U.S.; and

•compliance with any post-approval requirements, including the potential requirement to implement a REMS, and the potential requirement to conduct post-approval studies.

Table of Contents

The testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product candidates will be granted on a timely basis, if at all. Prior to beginning the first clinical trial with a product candidate, we must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an IND product to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical trials. The IND also includes results of animal and in vitro studies assessing the toxicology, pharmacokinetics, pharmacology, and pharmacodynamic characteristics of the product; chemistry, manufacturing, and controls information; and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

When a clinical trial using genetically engineered cells is conducted at, or sponsored by, institutions receiving NIH funding for wild-type DNA research, prior to the submission of an IND to the FDA, a protocol and related documentation is submitted to and the study is registered with the NIH Office of Biotechnology Activities (OBA) pursuant to the NIH Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines). Compliance with the NIH Guidelines is mandatory for investigators at institutions receiving NIH funds for research involving wild-type DNA, and many companies and other institutions not otherwise subject to the NIH Guidelines voluntarily follow them. The NIH is responsible for convening the Recombinant DNA Advisory Committee (RAC), a federal advisory committee that discusses protocols that raise novel or particularly important scientific, safety, or ethical considerations at one of its quarterly public meetings. The OBA will notify the FDA of the RAC’s decision regarding the necessity for full public review of a protocol. RAC proceedings and reports are posted to the OBA web site and may be accessed by the public. If the FDA allows the IND to proceed, but the RAC decides that full public review of the protocol is warranted, the FDA will request at the completion of its IND review that sponsors delay initiation of the protocol until after completion of the RAC review process.

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with GCP requirement, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB, for each site proposing to conduct the clinical trial, must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site and must monitor the study until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board, which provides authorization for whether or not a study may move forward at designated check points based on access to certain data from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries.

Table of Contents

For purposes of BLA or NDA approval, human clinical trials are typically conducted in three sequential phases that may overlap.

•Phase 1. The investigational product is initially introduced into healthy human subjects and tested for safety. In the case of some products for severe or life-threatening diseases, the initial human testing is often conducted in patients.

•Phase 2. The investigational product is evaluated in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy or potency of the product for specific targeted diseases and to determine dosage tolerance, optimal dosage and dosing schedule.

•Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy or potency, and safety in an expanded patient population at geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk to benefit ratio of the product and provide an adequate basis for product labeling.

•Phase 4. In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more information about the product. These so-called Phase 4 trials may be made a condition to approval of the BLA or NDA.

Phase 1, Phase 2 and Phase 3 testing may not be completed successfully within a specified period, if at all, and there can be no assurance that the data collected will support FDA approval or licensure of the product. Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the biological characteristics of the product candidate and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the Public Health Service Act emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the identity, strength, quality and purity of the final product, or for biologics, the safety, purity and potency. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

We may be required to develop and implement additional clinical trial policies and procedures designed to help protect subjects from the COVID-19 virus. For example, in March 2020, the FDA issued a guidance, which FDA subsequently updated, on conducting clinical trials during the pandemic, which describes a number of considerations for sponsors of clinical trials impacted by the pandemic, including the requirement to include in the clinical trial report contingency measures implemented to manage the trial, and any disruption of the trial as a result of the COVID-19 pandemic; a list of all subjects affected by the COVID-19-pandemic related study disruption by unique subject identifier and by investigational site and a description of how the individual’s participation was altered; and analyses and corresponding discussions that address the impact of implemented contingency measures (e.g., participant discontinuation from investigational product and/or study, alternative procedures used to collect critical safety and/or efficacy data) on the safety and efficacy results reported for the trial. In June 2020, FDA also published a guidance on Good Manufacturing Practice considerations for responding to COVID-19 infection in employees in drug and biological products manufacturing. The extent to which the COVID-19 pandemic impacts our business, preclinical studies and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence.

BLA/NDA Submission and Review by the FDA

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA for a biologic product candidate or an NDA for a small molecule product candidate requesting approval to market the product for one or more indications. The BLA/NDA must include all relevant data available from pertinent preclinical and clinical trials, including negative or ambiguous results, as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical trials intended to test the safety and effectiveness of a use of the product or from a number of alternative sources, including studies initiated by investigators. The submission of a BLA/NDA requires payment of a substantial user fee to the FDA, and the sponsor of an approved BLA/NDA is subject to annual product and establishment user fees. These fees typically increase annually. A waiver of user fees may be obtained under certain limited circumstances.

Table of Contents

Within 60 days following submission of the application, the FDA reviews a BLA/NDA to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to file any BLA or NDA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA/NDA must be resubmitted with the additional information. Once a BLA/NDA has been filed, the FDA’s goal is to review the application within ten months after it accepts the application for filing, or, if the application relates to an unmet medical need in a serious or life-threatening indication, six months after the FDA accepts the application for filing. The review process is often significantly extended by FDA requests for additional information or clarification. The FDA reviews a BLA/NDA to determine, among other things, whether a product is safe and effective, or safe, pure and potent for the proposed indication(s) and the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued safety, purity and potency or efficacy. The FDA may convene an advisory committee to provide clinical insight on application review questions. Before approving a BLA/NDA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities comply with cGMP requirements and are adequate to assure consistent production of the product within required specifications. If applicable, FDA regulations also require tissue establishments to register and list their human cells, tissues, and cellular and tissue-based products with the FDA and to evaluate donors through screening and testing. Additionally, before approving a BLA/NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

The testing and approval process require substantial time, effort and financial resources, and each may take several years to complete. The FDA may not grant approval on a timely basis, or at all, and we may encounter difficulties or unanticipated costs in our efforts to secure necessary governmental approvals, which could delay or preclude us from marketing our product candidates. After the FDA evaluates a BLA/NDA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, the FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A complete response letter indicates that the review cycle of the application is complete, and the application is not ready for approval. A complete response letter may request additional information or clarification. The FDA may delay or refuse approval of a BLA/NDA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

If regulatory approval of a product is granted, such approval may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA/NDA with a REMS plan to mitigate risks, which could include medication guides, physician communication plans, or other restrictions to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing regulatory standards is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more Phase 4 post-market trials and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization and may limit further marketing of the product based on the results of these post-marketing studies. In addition, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our product candidates under development.

A sponsor may seek approval of its product candidate under programs designed to accelerate the FDA’s review and approval of new drugs and biological products that meet certain criteria. Specifically, new drugs and biological products are eligible for Fast Track designation if they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. For a Fast Track product, the FDA may consider sections of the BLA/NDA for review on a rolling basis before the complete application is submitted if relevant criteria are met. A Fast Track-designated product candidate may also qualify for priority review. Priority review is granted when there is evidence that the proposed product would be a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious condition. If criteria are not met for priority review, the application is subject to the standard FDA review period. Priority review designation does not change the scientific/medical standard for approval or the quality of evidence necessary to support approval.

Under the accelerated approval program, the FDA may approve a BLA/NDA on the basis of either a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. Post-marketing studies or completion of ongoing studies after marketing approval are generally required to verify the product’s clinical benefit in relationship to the surrogate endpoint or ultimate outcome in relationship to the clinical benefit.

In addition, the Food and Drug Administration Safety and Innovation Act of 2012 (FDASIA) established Breakthrough Therapy designation. A sponsor may seek FDA designation of its product candidate as a Breakthrough Therapy if the product candidate is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the therapy may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Sponsors may request the FDA to designate a Breakthrough Therapy at the time of, or any time after, the submission of an IND, but ideally before an end-of-Phase 2 meeting with the FDA. If the FDA designates a Breakthrough Therapy, it may take actions appropriate to expedite the development and review of the application, which may include holding meetings with the sponsor and the review team throughout the development of the therapy; providing timely advice to, and interactive communication with, the sponsor regarding the development of the product candidate to ensure that the development program to gather the nonclinical and clinical data necessary for approval is as efficient as practicable; involving senior managers and experienced review staff, as appropriate, in a collaborative, cross-disciplinary review; assigning a cross-disciplinary project lead for the FDA review team to facilitate an efficient review of the development program and to serve as a scientific liaison between the review team and the sponsor; and considering alternative clinical trial designs when scientifically appropriate, which may result in smaller or more efficient clinical trials that require less time to complete and may minimize the number of patients exposed to a potentially less efficacious treatment. Breakthrough Therapy designation also allows the sponsor to file sections of the BLA/NDA for review on a rolling basis. We may seek designation as a Breakthrough Therapy for some or all of our product candidates.

Breakthrough Therapy and/or Fast Track designations and priority review do not change the standards for approval. The receipt of such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval.

In addition, the Pediatric Research Equity Act (PREA) requires a sponsor to conduct pediatric clinical trials for certain drugs and biological products, for a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration. Under PREA, original NDAs/BLAs and supplements must contain a pediatric assessment unless the sponsor has received a deferral or waiver. The required assessment must evaluate the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations and support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The sponsor or FDA may request a deferral of pediatric clinical trials for some or all of the pediatric subpopulations. A deferral may be granted for several reasons, including a finding that the product candidate is ready for approval for use in adults before pediatric clinical trials are complete or that additional safety or effectiveness data needs to be collected before the pediatric clinical trials begin. The FDA must send a non-compliance letter to any sponsor that fails to submit the required assessment, keep a deferral current or fails to submit a request for approval of a pediatric formulation.

Orphan Drugs

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 individuals in the U.S., or a patient population greater than 200,000 individuals in the U.S. and when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the U.S. will be recovered from sales in the U.S. for that drug or biologic. Orphan drug designation must be requested before submitting a BLA or 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.

Table of Contents

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease 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, including a full BLA or NDA, to market the same biologic or drug product 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 or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic 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 BLA application user fee.

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. In addition, orphan drug exclusive marketing rights in the U.S. 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.

Emergency Use Authorization

Operation Warp Speed (OWS) aimed to deliver 300 million doses of a safe, effective vaccine for COVID-19 by January 2021, and was part of a broader government strategy to accelerate the development, manufacturing, and distribution of COVID-19 vaccines, therapeutics, and diagnostics. OWS was a partnership among components of HHS, including the Centers for Disease Control and Prevention, the FDA, the NIH, and the Biomedical Advanced Research and Development Authority (BARDA) and the Department of Defense; engaged with private firms and other federal agencies; and coordinated existing HHS-wide efforts, including the NIH’s Accelerating COVID-19 Therapeutic Interventions and Vaccines partnership, NIH’s Rapid Acceleration of Diagnostics initiative, and work by BARDA. A COVID-19 vaccine product may be approved initially under an emergency use authorization (EUA) followed by a full BLA approval when more data are available and submitted to FDA for approval.

On February 4, 2020, the Secretary of HHS determined that the COVID-19 pandemic is a public health emergency that has a significant potential to affect national security or the health and security of U.S. citizens. On the basis of such determination, on March 27, 2020, the Secretary of HHS declared that circumstances exist justifying the authorization of emergency use of drugs and biologics during the COVID-19 outbreak, pursuant to Section 564 of the FDCA, which permits the FDA Commissioner to allow unapproved medical products or unapproved uses of approved medical products to be used in the COVID-19 public health emergency. FDA has created the Coronavirus Treatment Acceleration Program, a new program designed to expedite the development of potential COVID-19 therapies by using every tool at the agency’s disposal to determine if the therapies are safe and effective for their intended uses. In issuing an emergency use authorization, FDA will consider the totality of scientific evidence available to FDA regarding safety, efficacy and known and potential risks of such products and availability of alternatives to the emergency use products, among others. Emergency Use Authorizations issued by FDA will specify the scope authorization and conditions of authorization, including limitations on distribution and conditions related to product advertising and promotion. Once granted, an EUA is effective will be effective until the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biologics for prevention and treatment of COVID-19 is terminated under Section 564(b)(2) of the FDCA or the EUA is revoked under Section 564(g) of the FDCA, after which the product must be approved by FDA under a traditional pathway in order to remain on the market or to continue commercialization of the product.

Post-Approval Requirements

Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record keeping, reporting of adverse experiences, periodic reporting, distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing, annual user fee requirements for any marketed products and the establishments at which such products are manufactured, as well as new application fees for supplemental applications with clinical data. Biopharmaceutical manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and any third-party manufacturers that we may decide to use. Changes to the manufacturing process are strictly regulated and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us, and any third-party manufacturers, that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. We cannot be certain that we or our present or future suppliers will be able to comply with the cGMP regulations and other FDA regulatory requirements. If our present or future suppliers are not able to comply with these requirements, the FDA may, among other things, halt our clinical trials, require us to recall a product from distribution, or withdraw approval of the BLA or NDA.

Future FDA and state inspections may identify compliance issues at our facilities or at the facilities of contract manufacturers that may disrupt production or distribution, or require substantial resources to correct. In addition, discovery of previously unknown problems with a product or the failure to comply with applicable requirements may result in restrictions on a product, manufacturer or holder of an approved BLA or NDA, including withdrawal or recall of the product from the market or other voluntary, FDA-initiated or judicial action that could delay or prohibit further marketing.

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including AEs 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 restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

•restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

•fines, warning letters or holds on post-approval clinical trials;

•refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product license approvals;

•product seizure or detention, or refusal to permit the import or export of products; or

•injunctions or the imposition of civil or criminal penalties.

The FDA closely regulates the marketing, labeling, advertising and promotion of biologics or drug products. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA 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. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties, and exclusion from participation in governmental health programs, like Medicare and Medicaid. Physicians may prescribe legally available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject of off-label use of their products.

Premarket Clearance and Approval Requirements for Medical Devices

Each medical device we seek to commercially distribute in the U.S. will require either a prior 510(k) clearance, unless it is exempt (PMA) from the FDA. Generally, if a new device has a predicate that is already on the market under a 510(k) clearance, the FDA will allow that new device to be marketed under a 510(k) clearance; otherwise, a PMA is required. Medical devices are classified into one of three classes: Class 1, Class 2 or Class 3, depending on the degree of risk associated with each medical device and the extent of control needed to provide reasonable assurance of safety and effectiveness. Class 1 devices are deemed to be low risk and are subject to the general controls of the FDCA, such as provisions that relate to: adulteration; misbranding; registration and listing; notification, including repair, replacement, or refund; records and reports; and good manufacturing practices. Most Class 1 devices are classified as exempt from pre-market notification under section 510(k) of the FDCA, and therefore may be commercially distributed without obtaining 510(k) clearance from the FDA. Class 2 devices are subject to both general controls and special controls to provide reasonable assurance of safety and effectiveness. Special controls include performance standards, post market surveillance, patient registries and guidance documents. A manufacturer may be required to submit to the FDA a pre-market notification requesting permission to commercially distribute some Class 2 devices. Devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices, or devices deemed not substantially equivalent to a previously cleared 510(k) device, are placed in Class 3. A Class 3 device cannot be marketed in the U.S. unless the FDA approves the device after submission of a PMA. However, there are some Class 3 devices for which FDA has not yet called for a PMA. For these devices, the manufacturer must submit a pre-market notification and obtain 510(k) clearance in orders to commercially distribute these devices. The FDA can also impose sales, marketing or other restrictions on devices in order to assure that they are used in a safe and effective manner.

510(k) Clearance Pathway

When a 510(k) clearance is required, we must submit a pre-market notification to the FDA demonstrating that our proposed device is substantially equivalent to a predicate device, which is a previously cleared and legally marketed 510(k) device or a device that was in commercial distribution before May 28, 1976. By regulation, a pre-market notification must be submitted to the FDA at least 90 days before we intend to distribute a device. As a practical matter, clearance often takes significantly longer. To demonstrate substantial equivalence, the manufacturer must show that the proposed device has the same intended use as the predicate device, and it either has the same technological characteristics, or different technological characteristics and the information in the pre-market notification demonstrates that the device is equally safe and effective and does not raise different questions of safety and effectiveness. The FDA may require further information, including clinical data, to make a determination regarding substantial equivalence. If the FDA determines that the device, or its intended use, is not substantially equivalent to a previously cleared device or use, the FDA will place the device into Class 3.

There are three types of 510(k)s: traditional; special; and abbreviated. Special 510(k)s are for devices that are modified and the modification needs a new 510(k) but does not affect the intended use or alter the fundamental scientific technology of the device. Abbreviated 510(k)s are for devices that conform to a recognized standard. The special and abbreviated 510(k)s are intended to streamline review, and the FDA intends to process special 510(k)s within 30 days of receipt.

De Novo Classification

Medical device types that the FDA has not previously classified as Class 1, 2 or 3 are automatically classified into Class 3 regardless of the level of risk they pose. The Food and Drug Administration Modernization Act of 1997 established a new route to market for low to moderate risk medical devices that are automatically placed into Class 3 due to the absence of a predicate device, called the Request for Evaluation of Automatic Class 3 Designation (or the De Novo Classification Process).

Table of Contents

This procedure allows a manufacturer whose novel device is automatically classified into Class 3 to request down-classification of its medical device into Class 1 or Class 2 on the basis that the device presents low or moderate risk, rather than requiring the submission and approval of a PMA application. Prior to the enactment of the FDASIA, a medical device could only be eligible for de novo classification if the manufacturer first submitted a 510(k) pre-market notification and received a determination from the FDA that the device was not substantially equivalent. FDASIA streamlined the de novo classification pathway by permitting manufacturers to request de novo classification directly without first submitting a 510(k) pre-market notification to the FDA and receiving a not substantially equivalent determination. Under FDASIA, the FDA is required to classify the device within 120 days following receipt of the de novo application. If the manufacturer seeks reclassification into Class 2, the manufacturer must include a draft proposal for special controls that are necessary to provide a reasonable assurance of the safety and effectiveness of the medical device. In addition, the FDA may reject the reclassification petition if it identifies a legally marketed predicate device that would be appropriate for a 510(k) or determines that the device is not low to moderate risk or that general controls would be inadequate to control the risks and special controls cannot be developed.

Pre-market Approval Pathway

A PMA application must be submitted to the FDA for Class 3 devices for which the FDA has required a PMA. The PMA application process is much more demanding than the 510(k) pre-market notification process. A PMA application must be supported by extensive data, including but not limited to technical, preclinical, clinical trials, manufacturing and labeling to demonstrate to the FDA’s satisfaction reasonable evidence of safety and effectiveness of the device.

After a PMA application is submitted, the FDA has 45 days to determine whether the application is sufficiently complete to permit a substantive review and thus whether the FDA will file the application for review. The FDA has 180 days to review a filed PMA application, although the review of an application generally occurs over a significantly longer period of time and can take up to several years. During this review period, the FDA may request additional information or clarification of the information already provided. Also, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device.

Although the FDA is not bound by the advisory panel decision, the panel’s recommendations are important to the FDA’s overall decision making process. In addition, the FDA may conduct a preapproval inspection of the manufacturing facility to ensure compliance with the Quality System Regulation (QSR). The agency also may inspect one or more clinical sites to assure compliance with FDA’s regulations.

Upon completion of the PMA review, the FDA may: (i) approve the PMA application which authorizes commercial marketing with specific prescribing information for one or more indications, which can be more limited than those originally sought; (ii) issue an approvable letter which indicates the FDA’s belief that the PMA application is approvable and states what additional information the FDA requires or the post-approval commitments that must be agreed to prior to approval; (iii)issue a not approvable letter which outlines steps required for approval, but which are typically more onerous than those in an approvable letter, and may require additional clinical trials that are often expensive and time consuming and can delay approval for months or even years; or (iv) deny the application. If the FDA issues an approvable or not approvable letter, the applicant has 180 days to respond, after which the FDA’s review clock is reset.

Table of Contents

Clinical trials are almost always required to support PMA and are sometimes required for 510(k) clearance. In the U.S., for significant risk devices, these trials require submission of an application for an Investigational Device Exemption (IDE) to the FDA. The IDE application must be supported by appropriate data, such as animal and laboratory testing results, showing it is safe to test the device in humans and that the testing protocol is scientifically sound. The IDE must be approved in advance by the FDA for a specific number of patients at specified trial sites. During the trial, the sponsor must comply with the FDA’s IDE requirements for investigator selection, trial monitoring, reporting and recordkeeping. The investigators must obtain patient informed consent, rigorously follow the investigational plan and trial protocol, control the disposition of investigational devices and comply with all reporting and recordkeeping requirements. Clinical trials for significant risk devices may not begin until the IDE application is approved by the FDA and the appropriate IRBs at the clinical trial sites. An IRB is an appropriately constituted group that has been formally designated to review and monitor medical research involving subjects and which has the authority to approve, require modifications in, or disapprove research to protect the rights, safety and welfare of human research subjects. A nonsignificant risk device does not require FDA approval of an IDE; however, the clinical trial must still be conducted in compliance with various requirements of FDA’s IDE regulations and be approved by an IRB at the clinical trial sites. The FDA or the IRB at each site at which a clinical trial is being performed may withdraw approval of a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the benefits or a failure to comply with FDA or IRB requirements. Even if a trial is completed, the results of clinical testing may not demonstrate the safety and effectiveness of the device, may be equivocal or may otherwise not be sufficient to obtain approval or clearance of the product.

Sponsors of clinical trials of devices are required to register with clinical trials.gov, a public database of clinical trial information. Information related to the device, patient population, phase of investigation, study sites and investigators and other aspects of the clinical trial is made public as part of the registration.

Ongoing Medical Device Regulation by the FDA

Even after a device receives clearance or approval and is placed on the market, numerous regulatory requirements apply. These include:

•establishment registration and device listing;

•the QSR, which requires manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all aspects of the manufacturing process;

•labeling regulations and the FDA prohibitions against the promotion of products for uncleared, unapproved or off-label uses and other requirements related to promotional activities;

•medical device reporting regulations, which require that manufactures report to the FDA if their device may have caused or contributed to a death or serious injury, or if their device malfunctioned and the device or a similar device marketed by the manufacturer would be likely to cause or contribute to a death or serious injury if the malfunction were to recur;

•corrections and removal reporting regulations, which require that manufactures report to the FDA field corrections or removals if undertaken to reduce a risk to health posed by a device or to remedy a violation of the FDCA that may present a risk to health; and

•post market surveillance regulations, which apply to certain Class 2 or 3 devices when necessary to protect the public health or to provide additional safety and effectiveness data for the device.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, will require a new clearance or possibly a PMA. The FDA requires each manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with a manufacture’s determination. If the FDA disagrees with our determination not to seek a new 510(k) clearance, the FDA may retroactively require us to seek 510(k) clearance or possibly a PMA. The FDA could also require manufacturer to cease marketing and distribution and/or recall the modified device until 510(k) clearance or PMA is obtained. Also, in these circumstances, the manufacturer may be subject to significant regulatory fines and penalties.

Table of Contents

Some changes to an approved PMA device, including changes in indications, labeling or manufacturing processes or facilities, require submission and FDA approval of a new PMA application or PMA supplement, as appropriate, before the change can be implemented. Supplements to a PMA application often require the submission of the same type of information required for an original PMA application, except that the supplement is generally limited to that information needed to support the proposed change from the device covered by the original PMA. The FDA uses the same procedures and actions in reviewing PMA supplements as it does in reviewing original PMA applications.

FDA regulations require us to register as a medical device manufacturer with the FDA. Additionally, some states require us to register as a medical device manufacturer within the state. Because of this, the FDA and similar state agencies may inspect us on a routine basis for compliance with the QSR. These regulations require that the manufacturer maintain proper documentation in a prescribed manner with respect to manufacturing, testing and control activities. Further, the FDA requires medical device manufacturers to comply with various FDA regulations regarding labeling. Failure by us or by our suppliers to comply with applicable regulatory requirements can result in enforcement action by the FDA or state authorities, which may include any of the following sanctions:

•warning or untitled letters, fines, injunctions, consent decrees and civil penalties;

•customer notifications, voluntary or mandatory recall or seizure of our medical device product candidates;

•operating restrictions, partial suspension or total shutdown of production;

•delay in processing submissions or applications for new products or modifications to existing products;

•withdrawing approvals that have already been granted; and

•criminal prosecution.

The Medical Device Reporting laws and regulations require medical device manufacturers to provide information to the FDA when they receive or otherwise become aware of information that reasonably suggests the device may have caused or contributed to a death or serious injury as well as a device malfunction that likely would cause or contribute to death or serious injury if the malfunction were to recur. In addition, the FDA prohibits an approved device from being marketed for off-label use. 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 substantial monetary penalties and criminal prosecution.

Newly discovered or developed safety or effectiveness data may require changes to a product’s labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory clearance or approval of our medical device product candidates under development. Medical device manufacturers are also subject to other federal, state and local laws and regulations relating to safe working conditions, laboratory and manufacturing practices.

Other Healthcare Laws and Compliance Requirements

Our sales, promotion, medical education, clinical research and other activities following product approval will be subject to regulation by numerous regulatory and law enforcement authorities in the U.S. in addition to the FDA, including potentially the Federal Trade Commission, the Department of Justice, CMS, other divisions of HHS and state and local governments. Our promotional and scientific/educational programs must comply with the AKS, the FCA, physician payment transparency laws, privacy laws, security laws, and additional federal and state laws similar to the foregoing.

Table of Contents

The AKS prohibits, among other things, the knowing and willing, direct or indirect offer, receipt, solicitation or payment of remuneration in exchange for or to induce the referral of patients, including the purchase, order or lease of any good, facility, item or service that would be paid for in whole or part by Medicare, Medicaid or other federal health care programs. Remuneration has been broadly defined to include anything of value, including cash, improper discounts, and free or reduced-price items and services. The AKS has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, formulary managers, and beneficiaries on the other. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. 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 AKS. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all its facts and circumstances. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the AKS has been violated. The government has enforced the AKS to reach large settlements with healthcare companies based on sham research or consulting and other financial arrangements with physicians. Further, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the AKS constitutes a false or fraudulent claim for purposes of the FCA. Many states have similar laws that apply to their state health care programs, as well as private payors.

Federal false claims and false statement laws, including the FCA, imposes liability on persons or entities that, among other things, knowingly present or cause to be presented claims that are false or fraudulent or not provided as claimed for payment or approval by a federal health care program. The FCA has been used to prosecute persons or entities that “cause” the submission of claims for payment that are inaccurate or fraudulent, by, for example, providing inaccurate billing or coding information to customers, promoting a product off-label, submitting claims for services not provided as claimed, or submitting claims for services that were provided but not medically necessary. Actions under the FCA may be brought by the Attorney General, or as a qui tam action by a private individual, in the name of the government. Violations of the FCA can result in significant monetary penalties and treble damages. The federal government is using the FCA, and the accompanying threat of significant liability, in its investigation and prosecution of pharmaceutical and biotechnology companies throughout the country, for example, in connection with the promotion of products for unapproved uses and other illegal sales and marketing practices. The government has obtained multi-million and multi-billion dollar settlements under the FCA in addition to individual criminal convictions under applicable criminal statutes. In addition, certain companies that were found to be in violation of the FCA have been forced to implement extensive corrective action plans and have often become subject to consent decrees or corporate integrity agreements, restricting the manner in which they conduct their business.

HIPAA created additional federal criminal statutes that prohibit, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors; knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services; and willfully obstructing a criminal investigation of a healthcare offense. Like the AKS, the ACA amended the intent standard for certain healthcare fraud statutes under HIPAA such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

Given the significant size of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ and manufacturers’ compliance with applicable fraud and abuse laws. In addition, many states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. Additionally, to the extent that our product candidates, once commercialized, are sold in a foreign country, we may be subject to similar foreign laws.

Table of Contents

In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians and certain other healthcare providers and teaching hospitals. The ACA, among other things, under the federal Physician Payment Sunshine Act, imposed reporting requirements on certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, for payments or other transfers of value made by them to certain covered recipients, including physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Effective January 1, 2022, for data reported to the Centers for Medicare & Medicaid Services (CMS) in 2022, these reporting obligations with respect to covered recipients have been extended to include payments and transfers of value made to non-physician providers such as physician assistants and nurse practitioners. Covered manufacturers are required to collect and report detailed payment data and submit legal attestation to the accuracy of such data to the government each year. Failure to submit required information may result in civil monetary penalties for all payments, transfers of value or ownership or investment interests that are not timely, accurately and completely reported in an annual submission. Additionally, entities that do not comply with mandatory reporting requirements may be subject to a corporate integrity agreement. Certain states also mandate implementation of commercial compliance programs, impose restrictions on covered manufacturers’ marketing practices and/or require the tracking and reporting of gifts, compensation and other remuneration to physicians and other healthcare professionals.

We may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as amended by the Health Information Technology and Clinical Health Act of 2009 (HITECH) and their respective implementing regulations, impose specified requirements on certain health care providers, plans and clearinghouses, or collectively, covered entities, and their “business associates,” relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s security standards directly applicable to “business associates,” which includes independent contractors or agents of covered entities that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, certain states have their own laws that govern the privacy and security of health information in certain circumstances, many of which differ from each other and/or HIPAA in significant ways and may not have the same effect, thus complicating compliance efforts.

If our operations are found to be in violation of any of such laws or any other governmental regulations that apply to us, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, disgorgement, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs, imprisonment, contractual damages, reputational harm, and diminished profits and future earnings, any of which could adversely affect our ability to operate our business and our financial results. If any of the physicians or other providers, independent contractors, or entities with whom we do business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs and imprisonment, which could affect our ability to operate our business. Further, defending against any such actions can be costly, time-consuming and may require significant personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired.

In addition to the foregoing health care laws, we are also subject to the U.S. Foreign Corrupt Practices Act (FCPA) and similar worldwide anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to government officials or private-sector recipients for the purpose of obtaining or retaining business. The anti-corruption policy mandates compliance with the FCPA and similar anti-bribery laws applicable to our business throughout the world. However, we cannot assure you that such a policy or procedures implemented to enforce such a policy will protect us from intentional, reckless or negligent acts committed by our employees, distributors, partners, collaborators or agents. Violations of these laws, or allegations of such violations, could result in fines, penalties or prosecution and have a negative impact on our business, results of operations and reputation.

Coverage and Reimbursement

Sales of pharmaceutical products depend significantly on the extent to which coverage and adequate reimbursement are provided by third-party payors. Third-party payors include state and federal government health care programs, managed care providers, private health insurers and other organizations. Although we currently believe that third-party payors will provide coverage and reimbursement for our product candidates, if approved, we cannot be certain of this. Third-party payors are increasingly challenging the price, examining the cost-effectiveness, and reducing reimbursement for medical products and services. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. The U.S. government, state legislatures and foreign governments have continued implementing cost containment programs, including price controls, restrictions on coverage and reimbursement 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 revenues and results. We may need to conduct expensive clinical trials to demonstrate the comparative cost-effectiveness of our product candidates. The product candidates that we develop may not be considered cost-effective and thus may not be covered or sufficiently reimbursed. It is time consuming and expensive for us to seek coverage and reimbursement from third-party payors, as each payor will make its own determination as to whether to cover a product and at what level of reimbursement. Thus, one payor’s decision to provide coverage and adequate reimbursement for a product does not assure that another payor will provide coverage or that the reimbursement levels will be adequate. Moreover, a payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Reimbursement may not be available or sufficient to allow us to sell our product candidates on a competitive and profitable basis.

Healthcare Reform

The U.S. and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our product candidates profitably. Among policy makers and payors in the U.S. 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 U.S., the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

By way of example, in March 2010, the ACA was signed into law, intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Among the provisions of the ACA of importance to our potential product candidates are:

•an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents, apportioned among these entities according to their market share in certain government healthcare programs;

•an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average manufacturer price for branded and generic drugs, respectively;

•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;

•a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% (increased pursuant to the Bipartisan Budget Act of 2018, effective as of 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for a manufacturer’s outpatient drugs to be covered under Medicare Part D;

•extension of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;

•expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for certain individuals with income at or below 133% of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability;

Table of Contents

•expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program; and

•a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. These changes include, among others, the Budget Control Act of 2011, which mandates aggregate reductions to Medicare payments to providers of up to 2% per fiscal year effective April 1, 2013, and, due to subsequent legislative amendments, will remain in effect through 2030, with the exception of a temporary suspension implemented under various COVID-19 relief legislation from May 1, 2020 through March 31, 2022, followed by a 1% payment adjustment from April 1 to June 30, 2022 and a 2% payment adjustment beginning July 1, 2022, unless additional Congressional action is taken. In January 2013, President Obama signed into law the ARTA, which, 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 may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our product candidates, if approved, and, accordingly, our financial operations.

Under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates than it receives on the sale of products, which could have a material impact on our business. Further, in July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at increasing competition for prescription drugs. Congress is considering legislation that, if passed, could have significant impact on prices of prescription drugs covered by Medicare, including limitations on drug price increases. The impact of these regulations and any future healthcare measures and agency rules implemented by the Biden administration on us and the pharmaceutical industry as a whole is currently unknown. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates if approved. Complying with any new legislation and regulatory changes could be time-intensive and expensive, resulting in a material adverse effect on our business.

Since the enactment of the ACA, there have been judicial and Congressional challenges to certain aspects of the ACA. In June 2021, the United States Supreme Court held that Texas and other challengers had no legal standing to challenge the ACA, dismissing the case without specifically ruling on the constitutionality of the ACA. Accordingly, the ACA remains in effect in its current form. It is unclear how this Supreme Court decision, future litigation, or healthcare measures promulgated by the Biden administration will impact our business, financial condition and results of operations. Complying with any new legislation or changes in healthcare regulation could be time-intensive and expensive, resulting in material adverse effect on our business.

At the state level, individual states are increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including discounts, restrictions on certain product access and marketing cost disclosure and transparency measures. For example, a number of states are considering or have recently enacted state drug price transparency and reporting laws that could substantially increase our compliance burdens and expose us to greater liability under such state laws once we begin commercialization after obtaining regulatory approval for any of our products. These measures could reduce the demand for our products, if approved, or impose additional pricing pressures on how much we can charge for our products if approved.

We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and lower reimbursement and in additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our product candidates. Furthermore, the current presidential administration and Congress may continue to attempt broad sweeping changes to the current health care laws. We face uncertainties that might result from modifications or repeal of any of the provisions of the ACA, including as a result of current and future executive orders and legislative actions. The impact of those changes on us and potential effect on the pharmaceutical and biotechnology industries as a whole is currently unknown. However, any changes to the ACA are likely to have an impact on our results of operations and may have a material adverse effect on our results of operations. We cannot predict what other healthcare programs and regulations will ultimately be implemented at the federal or state level or the effect any future legislation or regulation in the U.S. may have on our business.

Foreign Regulation

In addition to regulations in the U.S., we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our product candidates to the extent we choose to develop or sell any product candidates outside of the U.S. The approval process varies from country to country and the time may be longer or shorter than that required to obtain FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

Human Capital

Our Human Capital Talent Strategy relies on attracting, retaining and developing top talent that align with our culture and mission to “outsmart your disease”. We promote a culture that is focused on delivering treatments utilizing natural immunities, and we seek to harness our science first focus to deliver solutions to patients and families. As of December 31, 2021, we had 587 employees located in our offices in Southern California, Washington, Colorado, Florida, North Carolina, Massachusetts, and Italy. Among our employees, 23% are focused on research and development, 13% on clinical development and regulatory, 45% on manufacturing and quality, and 19% on general and administrative functions. We have not been subject to labor action or union activities, and our management considers its relationships with employees to be good.

We believe that fostering a workplace that celebrates differences and strengths creates an environment that supports the inclusion and value of diverse thoughts, backgrounds and perspectives. A well rounded culture allows for ongoing dialogue and discussions that challenge the status quo and create a learning environment that supports diversity, equity and inclusion. As part of our commitment we continue to encourage a culture where employees can freely ask questions and raise concerns. Our annual performance review process helps support our commitment to develop and retain top talent by providing an opportunity to have open dialogue, establish goals, discuss milestones and continue to engage in opportunities to develop and cultivate the talent. Additionally, our management team makes themselves available to all employees including 1:1s, Department Meetings and Town Hall events.

Our ongoing success will continue to depend on our ability to attract, engage and retain top talent in an ever growing competitive market. We offer a competitive compensation package to help meet the needs of our employees. In addition to salaries, these programs include annual bonuses, stock awards, a 401(k) plan, healthcare and insurance benefits, flexible spending accounts, paid time off, family leave, flexible work schedules, an employee assistance program, among others. We work to ensure pay equity by assessing our compensation practices and working with external benchmarks and compensation consultants to design and benchmark our programs.

Our ongoing response to the COVID-19 pandemic, which complies with government orders in all the states and counties where we operate, focuses on employee health and wellness. We implemented a number of health-related measures over the past two years. We continue to support a general work from home policy and restrict on-site access to essential employees such as laboratory personnel, increasing hygiene, cleaning and sanitizing procedures at our office and laboratory facilities, requiring face masks be worn while on company premises, and implementing temperature checks and COVID-19 testing requirements in order to enter company facilities.

Organization and Development of ImmunityBio, Inc.

ImmunityBio, Inc. was established following a series of mergers and name changes. We were incorporated in Illinois on October 7, 2002 under the name ZelleRx Corporation. Our name was later changed to Conkwest, Inc., and we were reincorporated in the state of Delaware in March 2014. On July 10, 2015, we changed our name to NantKwest, Inc.

NantCell, LLC was originally organized as a Delaware limited liability company in November 2014. In April 2015, it was converted to a Delaware corporation, NantCell, Inc., and in May 2019 changed its name to ImmunityBio, Inc. (a private company).

Table of Contents

On December 21, 2020, NantKwest, Inc. and ImmunityBio, Inc. entered into a merger agreement (the Merger Agreement) providing for the combination of the two companies (the Merger), with NantKwest, Inc. being the surviving company which then changed its name to ImmunityBio, Inc. (and ImmunityBio, Inc., a private company, changed its name back to NantCell, Inc. and is now our wholly owned subsidiary). At the time, NantKwest, Inc. was an innovative, clinical-stage immunotherapy company focused on harnessing the power of the innate immune system to treat cancer and infectious diseases, and ImmunityBio, Inc. was a clinical-stage immunotherapy company developing next-generation therapies that drive immunogenic mechanisms for defeating cancer and infectious diseases, with an immunotherapy platform designed to activate both the innate and adaptive immune systems to create long-term “immunological memory.” We believe that the Merger, which closed on March 9, 2021 as described below, combined two companies to create a clinical-stage biotechnology company developing next-generation therapies and vaccines that complement, harness, and amplify the immune system to defeat cancers and infectious diseases.

ImmunityBio is incorporated in Delaware and its principal executive offices are located in San Diego, California.

ITEM 1A. RISK FACTORS.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, any of which may be relevant to decisions regarding an investment in or ownership of our stock. The occurrence of any of these risks could have a significant adverse effect on our reputation, business, financial condition, results of operations, growth and ability to accomplish our strategic objectives. We have organized the description of these risks into groupings in an effort to enhance readability, but many of the risks interrelate or could be grouped or ordered in other ways, so no special significance should be attributed to the groupings or order below.

On March 9, 2021, we completed the Merger with ImmunityBio, Inc., a private company referred to below as “ImmunityBio.” After the completion of this Merger, we (formerly known as NantKwest, Inc.) changed our name to ImmunityBio, Inc., and references below to “the company,” “the combined company,” “we,” “us,” and “our” refer to ImmunityBio, Inc. and its subsidiaries.

Risk Factor Summary

Risks Related to Our Limited Operating History, Financial Condition and Capital Requirements

•We will need additional financing to fund our operations and complete the development and commercialization of our various product candidates, and if we are unable to obtain such financing when needed, or on acceptable terms, we may be unable to complete the development and commercialization of our product candidates.

•Our debt could adversely affect our cash flows and limit our flexibility to raise additional capital.

•Our businesses may not be integrated successfully, or such integration may be more difficult, time consuming or costly than expected.

•We are a clinical-stage biotechnology company with a limited operating history and no products approved for commercial sale. We have a history of operating losses, and we expect to continue to incur losses and may never be profitable, which together with our limited operating history, makes it difficult to assess our future viability.

Table of Contents

Risks Related to the Discovery, Development and Commercialization of our Product Candidates

•We will be substantially dependent on the success of our product candidates and cannot guarantee that these product candidates will successfully complete development, receive regulatory approval or be successfully commercialized.

•We may develop product candidates in combination with other therapies, which exposes us to additional risks.

•We may choose to expend our limited resources on programs that do not yield successful product candidates as opposed to indications that may be more profitable or for which there is a greater likelihood of success.

•Our projections regarding the market opportunities for our product candidates may not be accurate, and the actual market for our products, if approved, may be smaller than we estimate.

•Our clinical trials may fail to adequately demonstrate the safety and efficacy of our product candidates, which would prevent or delay regulatory approval and commercialization. If our trials are not successful, we will be unable to commercialize our product candidates.

Risks Related to Reliance on Third Parties

•We have limited experience conducting clinical trials and have relied and will rely on third parties and related parties to conduct many of our preclinical studies and clinical trials, to manufacture products and to perform many essential services for any products that we commercialize, including services related to distribution, government price reporting, customer service, accounts receivable management, cash collection and AE reporting. Any failure by a third party, related party, or by us to perform as expected, to comply with legal and regulatory requirements or to conduct the clinical trials according to Good Clinical Practice (GCP) regulations, and in a timely manner, may delay or prevent our ability to seek or obtain regulatory approval for or commercialization of our product candidates and our ability to commercialize our current or future product candidates will be significantly impacted and we may be subject to regulatory sanctions.

•We use the Clinic, a related party, in some of our clinical trials which may expose us to significant regulatory risks. If our data for this site is not sufficiently robust or if there are any data integrity issues, we may be required to repeat such studies or required to contract with other clinical trial sites, and our clinical development plans will be significantly delayed, and we will incur additional costs.

•We have formed, and may in the future form or seek, strategic alliances or enter into collaborations with third parties or additional licensing arrangements in the future, and we may not realize the benefits of such alliances or licensing arrangements. If we fail to enter into such strategic alliances, collaborations or licensing arrangements, or such strategic alliances, collaborations or licensing arrangements are not successful, we may not be able to capitalize on the market potential of our product candidates.

•If conflicts arise between us and our collaborators or strategic partners, these parties may act in a manner adverse to us and could limit our ability to implement our strategies.

Table of Contents

Risks Related to Healthcare and Other Government Regulations

•We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our product candidates. We are, and if we receive regulatory approval of our product candidates, will continue to be subject to ongoing extensive regulation, regulatory obligations and continued regulatory review, which may result in significant additional expense.

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

•If we fail to comply with U.S. and foreign regulatory requirements, regulatory authorities could limit or withdraw any marketing or commercialization approvals we may receive and subject us to other penalties that could materially harm our business. For example, our GMP-in-a-Box will be regulated by the FDA as a medical device, and regulatory compliance for medical devices is expensive, complex and uncertain, and a failure to comply could lead to enforcement actions against us and other negative consequences for our business.

•We are and will be subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws and anti-money laundering laws and regulations. Compliance with these legal standards could impair our ability to compete in domestic and international markets. We can face criminal and/or civil liability and other serious consequences for violations, which can harm our business.

Risks Related to Intellectual Property

•If we are unable to obtain, maintain, protect and enforce patent protection and other proprietary rights for our product candidates and technologies, we may not be able to compete effectively or operate profitably and our ability to prevent our competitors from commercializing similar or identical technology and product candidates would be adversely affected.

•If any of our owned or in-licensed patent applications do not issue as patents in any jurisdiction, we may not be able to compete effectively.

•We or our licensors, collaborators, or any future strategic partners may become subject to third-party claims or litigation alleging infringement of patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or enforce our patents or other intellectual property or the patents or other intellectual property of our licensors, all of which could be expensive, time-consuming and unsuccessful, may delay or prevent the development and commercialization of our product candidates, or may put our patents and other proprietary rights at risk.

•The use of our technology and product candidates could potentially conflict with the rights of others, and third-party claims of intellectual property infringement, misappropriation or other violation against us, our licensors or our collaborators may prevent or delay the development and commercialization of our product candidates and technologies.

•Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

Table of Contents

Risks Related to Our Common Stock

•Dr. Patrick Soon-Shiong, our Executive Chairman, Global Chief Scientific and Medical Officer and our principal stockholder, has significant interests in other companies which may conflict with our interests.

•Dr. Soon-Shiong, through his voting control of the company, has the ability to control actions that require stockholder approval.

•The market price of our common stock has been and may continue to be volatile, and investors may have difficulty selling their shares.

Risks Related to Our Limited Operating History, Financial Condition and Capital Requirements

We will need additional financing to fund our operations and complete the development and commercialization of our various product candidates, and if we are unable to obtain such financing when needed, or on acceptable terms, we may be unable to complete the development and commercialization of our product candidates.

The development of biopharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive and uncertain process that takes years to complete. Our operations have consumed substantial amounts of cash since inception. A significant portion of our funding had been in the form of promissory notes totaling $605.6 million in indebtedness (consisting of related-party promissory notes and accrued and unpaid interest, less unamortized debt issuance costs) as of December 31, 2021 held by entities affiliated with Dr. Soon-Shiong.

As of December 31, 2021, we held cash, cash equivalents and marketable securities totaling $317.9 million. We will need to obtain additional financing to fund our future operations, including completing the development and commercialization of our product candidates. Changing circumstances may cause us to increase our spending significantly faster than we currently anticipate and we may need to raise additional funds sooner than we presently anticipate. Moreover, research and development and our operating costs and fixed expenses such as rent and other contractual commitments, including those for our research collaborations, are substantial and are expected to increase in the future.

To the extent that we raise additional capital through the sale of equity or equity-linked securities, including convertible debt, or through our at-the-market offering (the ATM) or other offerings, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of additional indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms unfavorable to us. We have no committed source of additional capital and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may be required to delay or reduce the scope of or eliminate one or more of our research or development programs or our commercialization efforts. Our current license and collaboration agreements may also be terminated if we are unable to meet the payment obligations under those agreements. As a result, we may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.

Table of Contents

Our debt could adversely affect our cash flows and limit our flexibility to raise additional capital.

We have a significant amount of debt and may need to incur additional debt to support our growth. As of December 31, 2021, our indebtedness totals $605.6 million, (consisting of related-party promissory notes and accrued and unpaid interest, less unamortized debt issuance costs), held by entities affiliated with Dr. Soon-Shiong.

Our substantial amount of debt could have important consequences and could:

•require us to dedicate a substantial portion of our cash and cash equivalents to make interest and principal payments on our debt, reducing the availability of our cash and cash equivalents and cash flow from operations to fund future capital expenditures, working capital, execution of our strategy and other general corporate requirements;

•increase our cost of borrowing and even limit our ability to access additional debt to fund future growth;

•increase our vulnerability to general adverse economic and industry conditions and adverse changes in governmental regulations;

•limit our flexibility in planning for, or reacting to, changes in our business and industry, which may place us at a disadvantage compared with our competitors; and

•limit our ability to borrow additional funds, even when necessary to maintain adequate liquidity, which would also limit our ability to further expand our business.

The occurrence of any of the foregoing factors could have a material adverse effect on our business, results of operations and financial condition.

We may need to refinance a portion of our outstanding debt as it matures. In particular, we have a $300.0 million promissory note with an entity affiliated with Dr. Soon-Shiong that becomes due and payable on December 17, 2022. In the event of a default on the loan (as defined in the promissory note), including if we do not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at a price equal to $5.67 per share. If we decide to convert this note into shares of common stock, it may be dilutive to our current stockholders. There can be no assurance that we can refinance this promissory note or what terms will be available in the market at the time of refinancing. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to the refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

Our businesses may not be integrated successfully, or such integration may be more difficult, time consuming or costly than expected.

The combination of two businesses is complex, costly and time-consuming and may divert significant management attention and resources to combining our prior businesses. This process may disrupt our businesses. The failure to meet the challenges involved in combining the two businesses and to realize the anticipated benefits of the Merger could cause an interruption of, or a loss of momentum in, the activities of the combined company and could adversely affect the results of operations of the combined company. Our ability to realize the anticipated benefits of the Merger will depend, to a large extent, on our ability to integrate our businesses in a manner that facilitates growth opportunities and achieves the projected synergies identified by each company without adversely affecting current revenues and investments in future growth. The overall combination of our businesses may also result in material unanticipated problems, expenses, liabilities, competitive responses, and loss of customer and other business relationships.

Many of these factors are outside of our control, and any one of them could result in lower revenues, higher costs and diversion of management time and energy, which could materially impact the business, financial condition and results of operations of the combined company. In addition, a decline in the market price of the combined company’s common stock could adversely affect the company’s ability to issue additional securities and to obtain additional financing in the future.

We are a clinical-stage biotechnology company with a limited operating history and no products approved for commercial sale. We have a history of operating losses, and we expect to continue to incur losses and may never be profitable, which together with our limited operating history, makes it difficult to assess our future viability.

We are a clinical-stage biotechnology company with a limited operating history upon which you can evaluate our business and prospects, and we have a broad portfolio of product candidates at various stages of development. None of our products have been approved for commercial sale, and we have not generated any revenue from product sales, although we have generated revenues from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables and grant programs. In addition, we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biotechnology industry, including in connection with obtaining marketing approvals, manufacturing a commercial-scale product or arranging for a third party to do so on our behalf or conducting sales and marketing activities necessary for successful product commercialization. Because of the numerous risks and uncertainties associated with our product development efforts, we are unable to predict when we may become profitable, if at all.

Since the commencement of our operations, we have incurred significant losses each year, and, as of December 31, 2021 we had an accumulated deficit of $2.0 billion. We expect to continue to incur significant expenses as we seek to expand our business, including in connection with conducting research and development across multiple therapeutic areas, participating in clinical trial activities, continuing to acquire or in-license technologies, maintaining, protecting and expanding our intellectual property, seeking regulatory approvals, increasing our manufacturing capabilities and, upon successful receipt of FDA approval, commercializing our products. Moreover, we do not expect to have significant product sales or revenue in the near term, if ever.

If our research and development efforts are successful, we may also face the risks associated with the shift from development to commercialization of new products based on innovative technologies. Our ability to achieve profitability, if ever, is dependent upon, among other things, obtaining regulatory approvals for our product candidates and successfully commercializing our product candidates alone or with third parties. However, our operations may not be profitable even if one or more of our product candidates under development are successfully developed and produced and thereafter commercialized. Even if we do become profitable, we may not be able to sustain or increase our profitability on a quarterly or annual basis. As a result, it may be more difficult for you to assess our future viability than it could be if we had a longer operating history.

We invest our cash on hand in various financial instruments which are subject to risks that could adversely affect our business, results of operations, liquidity and financial condition.

We invest our cash in a variety of financial instruments, principally commercial paper, corporate debt securities and foreign government bonds. All of these investments are subject to credit, liquidity, market and interest rate risk. Such risks, including the failure or severe financial distress of the financial institutions that hold our cash, cash equivalents and investments, may result in a loss of liquidity, impairment to our investments, realization of substantial future losses, or a complete loss of the investments in the long-term, which may have a material adverse effect on our business, results of operations, liquidity and financial condition. In order to manage the risk to our investments, we maintain an investment policy that, among other things, limits the amount that we may invest in any one issue or any single issuer and requires us to only invest in high credit quality securities to preserve liquidity.

Risks Related to the Discovery, Development and Commercialization of our Product Candidates

We will be substantially dependent on the success of our product candidates and cannot guarantee that these product candidates will successfully complete development, receive regulatory approval or be successfully commercialized.

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, and the sale of our bioreactors and related consumables. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. We have invested a significant portion of our efforts and financial resources in the development of our main product candidates, an antibody cytokine fusion protein (Anktiva), saRNA and second-generation hAd5 vaccine candidates, and aldoxorubicin, some of which are used in combination with our NK cell therapy candidates. Our product candidates will require additional clinical and non-clinical development, regulatory approval, commercial manufacturing arrangements, establishment of a commercial organization, significant marketing efforts, and further investment before we can generate any revenues from product sales. We expect to invest heavily in these product candidates as well as in our other existing product candidates and in any future product candidates that we may develop. Our product candidates are susceptible to the risks of failure inherent at any stage of product development, including the appearance of unexpected AEs or failure to achieve primary endpoints in clinical trials. Furthermore, we cannot assure you that we will meet our timelines for current or future clinical trials, which may be delayed or not completed for a number of reasons. Additionally, our ability to generate revenues from our combination therapy products will also depend on the availability of the other therapies with which our products are intended to be used. We currently generate no meaningful revenues from the sale of any product candidates, and we may never be able to develop or commercialize a product.

We may develop product candidates in combination with other therapies, which exposes us to additional risks.

We may develop product candidates in combination with one or more other therapies. We are studying Anktiva therapy along with other products and product candidates, such as BCG, PD-L1 t-haNK, hAd5 and yeast TAAs, and aldoxorubicin. If we choose to develop a product candidate for use in combination with an approved therapy, we are subject to the risk that the FDA, EMA or comparable foreign regulatory authorities in other jurisdictions could revoke approval of, or that safety, efficacy, manufacturing or supply issues could arise with the therapy used in combination with our product candidate. The FDA may require us to use more complex clinical trial designs in order to evaluate the contribution of each product and product candidate to any observed effects. To the extent that we do not have rights to already approved products, this may require us to work with another company to satisfy such a requirement or increase our cost of development. It is possible that the results of these trials could show that any positive results are attributable to the already approved product. Following product approval, the FDA may require that products used in conjunction with each other be cross labeled for combined use. If the therapies we use in combination with our product candidates are replaced as the standard of care for the indications we choose for any of our product candidates, the FDA or comparable foreign regulatory authorities may require us to conduct additional clinical trials. The occurrence of any of these risks could result in our own products, if approved, being removed from the market or being less successful commercially.

In addition, unapproved therapies face the same risks described with respect to our product candidates currently in development and clinical trials, including the potential for serious adverse effects, delays in clinical trials and lack of FDA approval. If the FDA or comparable foreign regulatory authorities do not approve or revoke their approval of these other therapies, or if safety, efficacy, quality, manufacturing or supply issues arise with, the therapies we choose to evaluate in combination with any of our product candidates, we may be unable to obtain approval of or market such combination therapy.

Table of Contents

We may choose to expend our limited resources on programs that do not yield successful product candidates as opposed to indications that may be more profitable or for which there is a greater likelihood of success.

We do not have sufficient resources to pursue development of all or even a substantial portion of the potential opportunities that we believe will be afforded to us by our product candidates. Because we have limited resources and access to capital to fund our operations, our management must make strategic decisions as to which product candidates and indications to pursue and how much of our resources to allocate to each. Our management must also evaluate the benefits of developing in-licensed or jointly owned technologies, which in some circumstances we may be contractually obligated to pursue, relative to developing other product candidates, indications or programs. Our management has broad discretion to suspend, scale down, or discontinue any or all of these development efforts, or to initiate new programs to treat other diseases. If we select and commit resources to opportunities that we are unable to successfully develop, or we forego more promising opportunities, our business, financial condition and results of operations will be adversely affected.

Our projections regarding the market opportunities for our product candidates may not be accurate, and the actual market for our products, if approved, may be smaller than we estimate.

Since our current product candidates and any future product candidates will represent novel approaches to treating various conditions, it may be difficult, in any event, to accurately estimate the potential revenues from these product candidates. Accordingly, we may spend significant capital trying to obtain approval for product candidates that have an uncertain commercial market. Our projections of addressable patient populations that may benefit from treatment with our product candidates are based on our beliefs and estimates. These estimates, which have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations, or market research by third parties, may prove to be incorrect. Further, new studies or approvals of new therapeutics may change the estimated incidence or prevalence of these diseases. The number of patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for our product candidates may be limited or may not be amenable to treatment with our product candidates and may also be limited by the cost of our treatments and the reimbursement of those treatment costs by third-party payors. Even if we obtain significant market share for our product candidates, because the potential target populations may be small, we may never achieve profitability without obtaining regulatory approval for additional indications.

Our clinical trials may fail to adequately demonstrate the safety and efficacy of our product candidates, which would prevent or delay regulatory approval and commercialization. If our trials are not successful, we will be unable to commercialize our product candidates.

Our research and development programs are at various stages of development. The clinical trials of our product candidates as well as the manufacturing and marketing of our product candidates will be subject to extensive and rigorous review and regulation by numerous government authorities in the U.S. and in other countries where we intend to test and market our product candidates. Before obtaining regulatory approvals for the commercial sale of any of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that our product candidates are safe, pure, and potent for use in their target indications. Each product candidate must demonstrate an adequate risk versus benefit profile in its intended patient population and for its intended use. The risk/benefit profile required for product licensure will vary depending on these factors and may include not only the ability to show tumor shrinkage, but also adequate duration of response, a delay in the progression of the disease, and/or an improvement in survival. For example, response rates from the use of our product candidates may not be sufficient to obtain regulatory approval unless we can also show an adequate duration of response. The clinical trials for our product candidates under development may not be completed on schedule and regulatory authorities may ultimately disagree with our chosen endpoints or may find that our studies or study results do not support product approval and we cannot guarantee that the FDA or foreign regulatory authorities will interpret the results as we do or accept the therapeutic effects as valid endpoints in clinical trials necessary for market approval or they may find that our clinical trial design or conduct does not meet the applicable approval requirement and more trials could be required before we submit our product candidates for approval. Success in early clinical trials does not ensure that large-scale clinical trials will be successful, nor does it predict final results. Product candidates in later stages of clinical trials may fail to show the desired safety, tolerability and efficacy traits despite having progressed through preclinical studies and initial clinical trials and after reviewing test results, we or our collaborators may abandon projects that we might previously have believed to be promising.

Table of Contents

In addition, we do not have data on possible harmful long-term effects of our product candidates and do not expect to have this data in the near future. As a result, our ability to generate clinical safety and effectiveness data sufficient to support submission of a marketing application or commercialization of our product candidates is uncertain and is subject to significant risk.

Interim, initial, “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose preliminary, interim or top-line data from our preclinical studies and clinical trials, which are based on preliminary analyses of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available or as patients from our clinical trials continue other treatments for their disease. We also may make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, top-line or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Top-line data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, top-line data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors could result in volatility in the price of our common stock.

In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is typically selected from a more extensive amount of available information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Our clinical trials may not be initiated or completed when we expect, or at all, they may take longer and cost more to complete than we project, our clinical trial costs may be higher than for more conventional therapeutic technologies or drug products, and we may be required to conduct additional clinical trials or modify current or future clinical trials based on feedback we receive from the FDA.

We cannot guarantee that any current or future clinical trials will be conducted as planned or completed on schedule, if at all, or that any of our product candidates will receive regulatory approval. A failure of one or more clinical trials can occur at any stage of the clinical trial process, other events may cause us to temporarily or permanently stop a clinical trial, and our future clinical trials may not be successful.

Because our product candidates include, and we expect our future product candidates to include, candidates based on advanced therapy technologies, we expect that they will require extensive research and development and have substantial manufacturing costs. In addition, costs to treat patients and to treat potential side effects that may result from our product candidates can be significant. Some clinical trial sites may not bill, or obtain coverage from Medicare, Medicaid, or other third-party payors for some or all of these costs for patients enrolled in our clinical trials, and clinical trial sites outside of the U.S. may not reimburse for costs typically covered by third-party payors in the U.S., and as a result we may be required by those trial sites to pay such costs. Accordingly, our clinical trial costs are likely to be significantly higher per patient than those of more conventional therapeutic technologies or drug products.

Collaborations with other entities may be subject to additional delays because of the management of the trials, contract negotiations, the need to obtain agreement from multiple parties and the necessity of obtaining additional approvals for therapeutics used in the combination trials. These combination therapies will require additional testing and clinical trials will require additional FDA regulatory approval and will increase our future costs.

Table of Contents

Any inability to successfully complete preclinical and clinical development could result in additional costs to us, slow down our product development and approval process or impair our ability to commence product sales and generate revenues. In addition, if we make manufacturing changes to our product candidates, we may be required to, or we may elect to, conduct additional trials to bridge our modified product candidates to earlier versions. These changes may require FDA approval or notification and may not have their desired effect. The FDA may also not accept data from prior versions of the product to support an application, delaying our clinical trials or programs or necessitating additional clinical trials or preclinical studies. We may find that this change has unintended consequences that necessitates additional development and manufacturing work, additional clinical and preclinical studies, or that results in refusal to file or non-approval of a BLA and/or NDA.

Clinical trial delays could shorten any periods during which our product candidates have patent protection and may allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our product candidates and may harm our business and results of operations. In addition, we have in the past experienced clinical holds imposed upon certain of our or investigator-initiated clinical trials for various reasons, and we may experience further clinical trial holds in the future. If we fail to commence or complete, or experience delays in, any of our planned clinical trials, our stock price and our ability to conduct our business as currently planned could be harmed.

Even if one of our product candidates is approved and commercialized, we may not become profitable.

If approved for marketing by applicable regulatory authorities, our ability to generate revenues from our product candidates will depend on our ability to:

•price our product candidates competitively such that third-party and government reimbursement leads to broad product adoption;

•prepare a broad network of clinical sites for administration of our product;

•create market demand for our product candidates through our own marketing and sales activities, and any other arrangements to promote these product candidates that we may otherwise establish;

•receive regulatory approval for the targeted patient population(s) and claims that are necessary or desirable for successful marketing;

•manufacture product candidates through CMOs or in our own, or our affiliates’, manufacturing facilities in sufficient quantities and at acceptable quality and manufacturing cost to meet commercial demand at launch and thereafter;

•establish and maintain agreements with wholesalers, distributors, pharmacies, and group purchasing organizations on commercially reasonable terms;

•obtain, maintain, protect and enforce patent and other intellectual property protection and regulatory exclusivity for our product candidates;

•successfully commercialize any of our product candidates that receive regulatory approval;

•maintain compliance with applicable laws, regulations, and guidance specific to commercialization including interactions with health care professionals, patient advocacy groups, and communication of health care economic information to payors and formularies;

•achieve market acceptance of our product candidates by patients, the medical community, and third-party payors;

•achieve appropriate reimbursement for our product candidates;

Table of Contents

•maintain a distribution and logistics network capable of product storage within our specifications and regulatory guidelines, and further capable of timely product delivery to commercial clinical sites;

•effectively compete with other therapies or competitors; and

•following launch, assure that our product will be used as directed and that additional unexpected safety risks will not arise.

Even if the FDA approves Anktiva for certain indications, and even if we obtain significant market share for it, because the potential target population may be small, we may never achieve profitability without obtaining regulatory approval for additional indications. The FDA often approves new therapies initially only for use in patients with r/r metastatic disease, which may limit our patient population.

Additionally, we may not be able to obtain the labeling claims necessary or desirable for the promotion of our product candidates.

Additionally, in connection with the Merger with ImmunityBio, we assumed the obligation to issue CVRs to the former stockholders of Altor in connection with the acquisition of Altor. These CVRs become payable upon the attainment of certain regulatory and sales milestones related to Anktiva. The former Altor stockholders have the ability to choose to receive these payments either in cash, in an equivalent value of our common stock or in a combination of both cash and stock at the time such payments are due, except that Dr. Soon-Shiong and his related party, as prior stockholders of Altor, have irrevocably elected to receive all payments in respect of their CVRs in the form of our common stock. Such CVR payments to Dr. Soon-Shiong and his related party are approximately $279.5 million in aggregate.

We may, however, still be required to pay the other prior Altor stockholders up to $164.2 million for the CVRs relating to the regulatory milestone and up to $164.2 million for the CVRs relating to the sales milestone should they choose to have these CVRs paid in cash instead of common stock. If this were to occur, we may need to seek additional sources of capital, and we may not be able to achieve profitability or positive cash flow. We plan to collaborate with governmental, academic and corporate partners, including affiliates, to improve and develop Anktiva, hAd5 and other therapies for new indications for use in combination with other therapies and to improve and develop other product candidates, which may expose us to additional risks, or we may not realize the benefits of such collaborations.

If we encounter delays or difficulties enrolling and/or maintaining patients in our clinical trials, our clinical development activities and receipt of necessary marketing approvals could be delayed or otherwise adversely affected.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We may experience difficulties or delays in patient enrollment and retention in our clinical trials for a variety of reasons.

Because the number of qualified clinical investigators is limited, we may need to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. Moreover, because our product candidates represent a departure from more commonly used methods for cancer and/or viral disease treatment, potential patients and their doctors may be inclined to use conventional therapies, such as chemotherapy and approved immunotherapies that have established safety and efficacy profiles, rather than enroll patients in any future clinical trial.

Delays or failures in planned patient enrollment or retention may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates, or could render further development impossible.

Table of Contents

Our product candidates may cause undesirable side effects or have other properties that could halt their clinical development, delay or prevent their regulatory approval, limit their commercial potential or result in significant negative consequences.

Results of our trials could reveal a high and unacceptable severity and prevalence of side effects, AEs or unexpected characteristics. Combination immunotherapy that includes our current product candidates may be associated with more frequent AEs or additional AEs. Undesirable side effects or unacceptable toxicities caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials or order our clinical trials to be placed on clinical hold, and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities for any or all targeted indications. The FDA or comparable foreign regulatory authorities may also require additional data, clinical trials, or preclinical studies should unacceptable toxicities arise. We may need to abandon development or limit development of that product candidate to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk/benefit perspective. Toxicities associated with our clinical trials and product candidates may also negatively impact our ability to conduct clinical trials using tumor-infiltrating lymphocyte therapy in larger patient populations, such as in patients that have not yet been treated with other therapies or have not yet progressed on other therapies. Even if we were to receive product approval, such approval could be contingent on inclusion of unfavorable information in our product labeling, such as limitations on the indicated uses for which the products may be marketed or distributed, a label with significant safety warnings, including boxed warnings, contraindications, and precautions, a label without statements necessary or desirable for successful commercialization, or requirements for costly post marketing testing and surveillance, or other requirements, including a Risk Evaluation and Mitigation Strategy (REMS) to monitor the safety or efficacy of the products, and in turn prevent us from commercializing and generating revenues from the sale of our current or future product candidates. In addition, these serious adverse effects may not be appropriately recognized or managed by the treating medical staff, as toxicities resulting from our product candidates are not normally encountered in the general patient population and by medical personnel. They may have difficulty observing patients and treating toxicities, which may be more challenging due to personnel changes, shift changes, house staff coverage or related issues. This could lead to more severe or prolonged toxicities or even patient deaths, which could result in us or the FDA delaying, suspending or terminating one or more of our clinical trials and which could jeopardize regulatory approval. Any of these occurrences may materially harm our business, financial condition and prospects.

The manufacture of our product candidates is complex, and we may encounter difficulties in production, particularly with respect to process development, quality control, or scaling-up of our manufacturing capabilities. If we or our related parties, or any of our third-party manufacturers encounter such difficulties, our ability to provide adequate supply of our product candidates for clinical trials or our products for patients, if approved, could be delayed or stopped, or we may be unable to maintain a commercially viable cost structure.

The manufacture of our product candidates involves complex processes, especially for our biologics, vectors and cell therapy product candidates, which are complex, highly regulated and subject to multiple risks. As a result of the complexities, the cost to manufacture biologics, vectors and cell therapies is generally higher than traditional small molecule chemical compounds, and the manufacturing process is less reliable and is more difficult to reproduce. The manufacture of cell therapy products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of cell therapy products often encounter difficulties in production, particularly in scaling up initial production. These problems include difficulties with production costs and yields, quality control, including stability of the product candidate and quality assurance testing, shortages of qualified personnel and compliance with strictly enforced federal, state, local and foreign regulations. We may also find that the manufacture of our product candidates is more difficult than anticipated, resulting in an inability to produce a sufficient amount of our product candidates for our clinical trials or, if approved, commercial supply. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects, and other supply disruptions. Currently, our product candidates are manufactured using processes developed or modified by us, our affiliates or by our third-party research institution collaborators that we may not utilize for more advanced clinical trials or commercialization.

Table of Contents

Currently we manufacture our product candidates or we may use third-party CMOs or some of our related parties to manufacture our product candidates. Our clinical trials will need to be conducted with product candidates and materials that were produced under current Good Manufacturing Practices (cGMP) and/or Good Tissue Practice regulations, which are enforced by regulatory authorities. Our product candidates may compete with other products and product candidates for access to manufacturing facilities. Moreover, because of the complexity and novelty of our manufacturing process, there are only a limited number of manufacturers that operate under cGMP regulations and that are both capable of manufacturing our product candidates for us and willing to do so. If our CMOs should cease manufacturing for us, we would experience delays in obtaining sufficient quantities of our product candidates for clinical trials and, if approved, commercial supply. Further, our CMOs may breach, terminate, or not renew our agreements with them. If we were to need to find alternative manufacturing facilities it may take us significant time to find a replacement, if we are able to find a replacement at all and it would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved. The commercial terms of any new arrangement could be less favorable than our existing arrangements and the expenses relating to the transfer of necessary technology and processes could be significant.

Our failure to comply or our CMOs’ failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. We may not be able to demonstrate sufficient comparability between products manufactured at different facilities to allow for inclusion of the clinical results from patients treated with products from these different facilities, in our product registrations. We also are required to register certain clinical trials and post the results of certain completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so could result in enforcement actions and adverse publicity.

Reliance on third-party manufacturers entails exposure to risks to which we would not be subject if we manufactured the product candidate ourselves, including:

•inability to negotiate manufacturing and quality agreements with third parties under commercially reasonable terms;

•reduced day-to-day control over the manufacturing process for our product candidates as a result of using third-party manufacturers for all aspects of manufacturing activities;

•reduced control over the protection of our trade secrets, know-how and other proprietary information from misappropriation or inadvertent disclosure or from being used in such a way as to expose us to potential litigation;

•termination or nonrenewal of manufacturing agreements with third parties in a manner or at a time that may be costly or damaging to us or result in delays in the development or commercialization of our product candidates; and

•disruptions to the operations of our third-party manufacturers or suppliers caused by conditions unrelated to our business or operations, including the bankruptcy of the manufacturer or supplier.

Moreover, any problems or delays we or our CMOs experience in preparing for commercial scale manufacturing of a product candidate may result in a delay in the FDA approval of the product candidate or may impair our ability to manufacture commercial quantities or such quantities at an acceptable cost, which could result in the delay, prevention, or impairment of clinical development and commercialization of our product candidates and could adversely affect our business. Furthermore, if we or our CMOs fail to deliver the required commercial quantities of our product candidates on a timely basis and at reasonable costs, we would likely be unable to meet demand for our products and we would lose potential revenues. We may ultimately be unable to reduce the cost of goods for our product candidates to levels that will allow for an attractive return on investment if and when those product candidates are commercialized.

Table of Contents

In addition, the manufacturing process and facilities for any products that we may develop are subject to FDA and foreign regulatory authority approval processes, and we or our CMOs will need to meet all applicable FDA and foreign regulatory authority requirements, including cGMP, on an ongoing basis. The cGMP requirements include quality control, quality assurance and the maintenance of records and documentation. The FDA and other regulatory authorities enforce these requirements through facility inspections. Manufacturing facilities must submit to pre-approval inspections by the FDA that will be conducted after we submit our marketing applications, including our BLAs and NDAs, to the FDA. Manufacturers are also subject to continuing FDA and other regulatory authority inspections following marketing approval. Further, we and our third-party CMOs must supply all necessary chemistry, manufacturing and quality control documentation in support of a BLA or NDA on a timely basis. Our or our CMOs’ manufacturing facilities may be unable to comply with our specifications, cGMP, and with other FDA, state, and foreign regulatory requirements, and there is no guarantee that we or our CMOs will be able to successfully pass all aspects of a pre-approval inspection by the FDA or other foreign regulatory authorities.

Poor control of production processes can lead to the introduction of adventitious agents or other contaminants, or to inadvertent changes in the properties or stability of product candidates that may not be detectable in final product testing. If microbial, viral, environmental or other contaminations are discovered in our product candidates or in the manufacturing facilities in which our product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination which could delay clinical trials and adversely harm our business. If we or our CMOs are unable to reliably produce products to specifications acceptable to the FDA or other regulatory authorities, or in accordance with the strict regulatory requirements, we may not obtain or maintain the approvals we need to commercialize such products. Even if we obtain regulatory approval for any of our product candidates, there is no assurance that either we or our CMOs will be able to manufacture the approved product to specifications acceptable to the FDA or other regulatory authorities, to produce it in sufficient quantities to meet the requirements for the potential launch of the product, or to meet potential future demand. Deviations from manufacturing requirements may further require remedial measures that may be costly and/or time-consuming for us or a third party to implement and may include the temporary or permanent suspension of a clinical trial or commercial sales or the temporary or permanent closure of a facility. Any such remedial measures imposed upon us or third parties with whom we contract could materially harm our business.

As product candidates progress through preclinical and clinical trials to marketing approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize yield and manufacturing batch size, minimize costs and achieve consistent quality and results. 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 altered materials. 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 commercialize our product candidates, if approved, and generate revenues.

To the extent we use CMOs, we are ultimately responsible for the manufacture of our products, if approved, and product candidates. A failure to comply with these requirements may result in regulatory enforcement actions against our manufacturers or us, including fines and civil and criminal penalties, which could result in imprisonment, suspension or restrictions of production, injunctions, delay or denial of product approval or supplements to approved products, clinical holds or termination of clinical trials, warning or untitled letters, regulatory authority communications warning the public about safety issues with the biologic, refusal to permit the import or export of the products, product seizure, detention, or recall, operating restrictions, suits under the federal civil False Claims Act (FCA), corporate integrity agreements, consent decrees, or withdrawal of product approval.

Any of these challenges could delay completion of clinical trials, require bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidate, impair commercialization efforts, increase our cost of goods, and have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Cell-based therapies and biologics rely on the availability of reagents, specialized equipment and other specialty materials, which may not be available to us on acceptable terms or at all. For some of these reagents, equipment and materials, we rely or may rely on sole source vendors or a limited number of vendors, which could impair our ability to manufacture and supply our products, if approved.

We currently depend on a small number of suppliers for some of the materials used in, and processes required to develop, our product candidates. For some of these reagents, equipment and materials used in the manufacture of our product candidates, we rely, and we may in the future rely, on sole source vendors or a limited number of vendors. Some of these suppliers may not have the capacity to support clinical trials and commercial products manufactured under cGMP by biopharmaceutical firms or may otherwise be ill-equipped to support our needs. We also do not have supply contracts with many of these suppliers and may not be able to obtain supply contracts with them on acceptable terms or at all. Accordingly, we may experience delays in receiving key materials and equipment to support clinical or commercial manufacturing. An inability to continue to source product from any of these suppliers could adversely affect our ability to satisfy demand for our product candidates, which could adversely and materially affect our product sales and operating results or our ability to conduct clinical trials, either of which could significantly harm our business.

As we seek to develop and scale our manufacturing process, we expect that we will need to obtain rights to and supplies of certain materials and equipment to be used as part of that process. We may not be able to obtain rights to such materials on commercially reasonable terms, or at all, and if we are unable to alter our process in a commercially viable manner to avoid the use of such materials or find a suitable substitute, it would have a material adverse effect on our business. Even if we are able to alter our process so as to use other materials or equipment, such a change may lead to a delay in our clinical development and/or commercialization plans. If such a change occurs for a product candidate that is already in clinical testing, the change may require us to perform both ex vivo comparability studies and to collect additional data from patients prior to undertaking more advanced clinical trials.

Our ability to use net operating losses and research and development credits to offset future taxable income may be subject to certain limitations.

In general, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the Code), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating losses or tax credits (NOLs) or credits, to offset future taxable income or taxes. For these purposes, an ownership change generally occurs where the aggregate stock ownership of one or more stockholders or groups of stockholders who owns at least 5% of a corporation’s stock increases its ownership by more than 50 percentage points over its lowest ownership percentage within a specified testing period. We have not conducted a complete study to assess whether a change of control has occurred or whether there have been multiple changes of control since inception due to the significant complexity and cost associated with such a study. If we have experienced a change of control, as defined by Section 382, at any time since inception (including as a result of the Merger), utilization of the net operating loss carryforwards or research and development tax credit carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the net operating loss carryforwards or research and development tax credit carryforwards before utilization. In addition, our NOLs or credits may also be impaired under state law. Accordingly, we may not be able to utilize a material portion of our NOLs or credits.

Since we will need to raise substantial additional funding to finance our operations, we may experience further ownership changes in the future, some of which may be outside of our control. Limits on our ability to use our pre-change NOLs or credits to offset U.S. federal taxable income could potentially result in increased future tax liability to us if we earn net taxable income in the future. In addition, under the legislation commonly referred to as the Tax Cuts and Jobs Act of 2017 (TCJA), as modified by the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), the amount of NOLs generated in taxable periods beginning after December 31, 2017, that we are permitted to deduct in any taxable year beginning after December 31, 2020 is limited to 80% of our taxable income in such year, where taxable income is determined without regard to the NOL deduction itself. The TCJA allows post-2017 unused NOLs to be carried forward indefinitely. Similar rules may apply under state tax laws.

Our transfer pricing policies may be subject to challenge by the Internal Revenue Service or other taxing authorities.

Our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with our determinations as to the value of assets sold or acquired or income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position were not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows, and lower overall profitability of our operations. We believe that our financial statements reflect adequate reserves to cover such a contingency, but there can be no assurances in that regard.

Because our current product candidates represent, and our other potential product candidates will represent, novel approaches to the treatment of disease, there are many uncertainties regarding the development, market acceptance, public opinion, third-party reimbursement coverage and the commercial potential of our product candidates, which may impact public perception of us and our product candidates and which may adversely affect our ability to conduct our business and implement our business plans.

Human immunotherapy products are a new category of therapeutics. We use relatively novel technologies involving Anktiva, saRNA, hAd5 and yeast technologies, aldoxorubicin, and cell-based therapies, and our NK cell platform utilizes a relatively novel technology involving the genetic modification of human cells and utilization of those modified cells in other individuals. Because this is a relatively new and expanding area of novel therapeutic interventions, there are many uncertainties related to development, marketing, reimbursement and the commercial potential for our product candidates. There can be no assurance as to the length of the trial period, the number of patients the FDA will require to be enrolled in the trials in order to establish the safety, efficacy, purity and potency of immunotherapy products, or that the data generated in these trials will be acceptable to the FDA to support marketing approval. Adverse public attitudes may adversely impact our ability to enroll patients in clinical trials. The FDA may take longer than usual to come to a decision on any BLA and/or NDA that we submit and may ultimately determine that there is not enough data, information, or experience with our product candidates to support an approval decision. The FDA may also require that we conduct additional post-marketing studies or implement risk management programs, such as REMS, until more experience with our product candidates is obtained. Finally, after increased usage, we may find that our product candidates do not have the intended effect, do not work with other combination therapies or have unanticipated side effects, potentially jeopardizing initial or continuing regulatory approval and commercial prospects. More restrictive government regulations or negative public opinion could have an adverse effect on our business or financial condition and may delay or impair the development and commercialization of our product candidates or demand for any products we may develop. AEs in our clinical trials, even if not ultimately attributable to our product candidates, and the resulting publicity could result in increased governmental regulation, unfavorable public perception, potential regulatory delays in the testing or approval of our potential product candidates, stricter labeling requirements for those product candidates that are approved and a decrease in demand for any such product candidates.

There is no assurance that the approaches offered by our product candidates will gain broad acceptance among doctors or patients or that governmental agencies or third-party medical insurers will be willing to provide reimbursement coverage for our proposed product candidates. Public perception may be influenced by claims, such as claims that our technologies are unsafe, unethical or immoral and, consequently, our approach may not gain the acceptance of the public or the medical community. Negative public reaction to cell-based immunotherapy in general could result in greater government regulation and stricter labeling requirements of immunotherapy products, including our product candidates, and could cause a decrease in the demand for any products we may develop. Moreover, our success will depend upon physicians specializing in the treatment of those diseases that our product candidates target prescribing, and their patients being willing to receive treatments that involve the use of our product candidates in lieu of, or in addition to, existing treatments they are already familiar with and for which greater clinical data may be available. The market for any products that we successfully develop will also depend on the cost of the product. We do not yet have sufficient information to reliably estimate what it will cost to commercially manufacture our current product candidates, and the actual cost to manufacture these products could materially and adversely affect the commercial viability of these products. Our goal is to reduce the cost of manufacturing and providing our therapies. However, unless we can reduce those costs to an acceptable amount, we may never be able to develop a commercially viable product.

Table of Contents

If we do not successfully develop and commercialize products based upon our approach or find suitable and economical sources for materials used in the production of our potential products, we will not become profitable, which would materially and adversely affect the value of our common stock. Our Anktiva therapies and our other therapies may be provided to patients in combination with other agents provided by third parties or our affiliates. The cost of such combination therapy may increase the overall cost of therapy and may result in issues regarding the allocation of reimbursements between our therapy and the other agents, all of which may affect our ability to obtain reimbursement coverage for the combination therapy from governmental or private third-party medical insurers.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.

We face an inherent risk of product liability as a result of the clinical development, testing and manufacturing of our product candidates and will face an even greater risk if we commercialize any products. For example, we may be sued if our product candidates cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. Large judgements have been awarded in class action lawsuits based on therapeutics that had unanticipated side effects. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in a regulatory investigation of the safety and effectiveness of our products, our third-party manufacturer’s manufacturing processes and facilities or our marketing programs and potentially a recall of our products or more serious enforcement action, including limitations on the approved indications for which our product candidates may be used or suspension or withdrawal of approvals, decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price.

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of products we may develop, alone or with corporate collaborators. Our insurance policies may also have various exclusions, and we may be subject to product liability claims for which we have no coverage. While we have obtained clinical trial insurance for our clinical trials, we may have to pay amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

We will face significant competition from other biotechnology and pharmaceutical companies and from non-profit institutions.

Competition in the field of cancer and viral infectious disease therapy is intense and is accentuated by the rapid pace of technological development. We compete with a variety of multi-national biopharmaceutical companies and specialized biotechnology companies, as well as technology being developed at universities and other research institutions. These competitors have developed, may develop and are developing product candidates and processes competitive with our product candidates. Research and discoveries by others may result in breakthroughs which may render our product candidates obsolete even before they generate any revenues. We believe that a significant number of products are currently under development, and may become commercially available in the future, for the treatment of conditions for which we are developing product candidates. Many of our competitors have several therapeutic products that have already been developed, approved and successfully commercialized, or are in the process of obtaining regulatory approval for their therapeutic products in the U.S. and internationally. Many of our competitors, either alone or with their strategic partners, have substantially greater financial, technical, and human resources than we do, as well as significantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of treatments and commercializing those treatments.

Table of Contents

Accordingly, our competitors may be more successful in obtaining approval of treatments and achieving widespread market acceptance, rendering our treatments obsolete or non-competitive, possibly even before we are able to enter the market. Accelerated merger and acquisition activity in the biotechnology and biopharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or 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 and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Even if we obtain regulatory approval for our product candidates, the availability and price of our competitors’ products could limit the demand and the price we are able to charge for our therapies. The level of generic competition and the availability of reimbursement from government and other third-party payors will also significantly affect the pricing and competitiveness of our products.

A large number of companies, government agencies and academic centers around the world are developing COVID‑19 vaccines, and many of these entities are in more advanced stages of development than we are, including some that have started Phase 2 and/or 3 clinical trials or have already obtained emergency regulatory approval in the U.S. and internationally. Even if our COVID‑19 vaccine candidate is ultimately approved for marketing, the value of our opportunity will be adversely impacted by other COVID‑19 vaccines that have obtained emergency regulatory approval, obtain full regulatory approval, or demonstrate better efficacy or safety than our COVID‑19 vaccine candidate.

We may not be able to implement our business plan if the acceptance of our product candidates is inhibited by price competition or the reluctance of physicians to switch from other methods of treatment to our product, or if physicians switch to other new therapies, drugs or biologic products or choose to reserve our product candidates for use in limited circumstances. We may be adversely impacted if any of these competitors gain market share as a result of new technologies, commercialization strategies or otherwise.

We may seek orphan drug status or Fast Track or Breakthrough Therapy designations or other designation for one or more of our product candidates, but even if any such designation or status is granted, it may not lead to a faster development process or regulatory review and may not increase the likelihood that our product candidates will receive marketing approval, and we may be unable to maintain any benefits associated with such designations or status, including market exclusivity.

In 2012, the FDA established a Breakthrough Therapy designation, which is intended to expedite, although there is no guarantee, the development and review of products that treat serious or life-threatening conditions. We have been awarded, and may seek in the future, Fast Track or Breakthrough Therapy designation for current or future product candidates. Receipt of a designation to facilitate product candidate development is within the discretion of the FDA. Accordingly, even if we believe one of our product candidates meets the criteria for a designation, the FDA may disagree. In any event, the receipt of such a designation for a product candidate may not result in a faster development process, review or approval compared to product candidates considered for approval under conventional FDA procedures and does not assure ultimate marketing approval by the FDA. In addition, the FDA may later decide that the product candidates no longer meet the designation conditions.

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition or for which there is no reasonable expectation that the cost of developing and making available the drug or biologic will be recovered from sales in the U.S. If a product that has orphan drug designation subsequently receives the first FDA approval for the disease 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, including a full BLA to market the same drug or biologic for the same indication for seven years, except in limited circumstances. We may seek orphan drug status for one or more of our product candidates, but exclusive marketing rights in the U.S. may be lost if we seek approval for an indication broader than the orphan designated indication and may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

Table of Contents

As a condition of approval, the FDA may require that we implement various post-marketing requirements and conduct post-marketing studies, any of which would require a substantial investment of time, effort, and money, and which may limit our commercial prospects.

As a condition of biologic licensing, the FDA is authorized to require that sponsors of approved BLAs implement various post-market requirements, including REMS and Phase 4 trials. For example, in connection with FDA approval of another company’s drug, the FDA required significant post-marketing commitments, including a Phase 4 trial, revalidation of a test method, and a substantial REMS program that included, among other requirements, the certification of hospitals and their associated clinics that dispensed the drug, including the implementation of a training program and limited distribution only to certified hospitals and their associated clinics. If we receive approval of our product candidates, the FDA may determine that similar or additional or more burdensome post-approval requirements are necessary to ensure that our product candidates are safe, pure and potent. To the extent that we are required to establish and implement any post-approval requirements, we will likely need to invest a significant amount of time, effort and money. Such post-approval requirements may also limit the commercial prospects of our product candidates.

We have never commercialized a product candidate before, and we may lack the necessary expertise, personnel and resources to successfully commercialize any products on our own or together with suitable collaborators. We may be unable to establish effective marketing and sales capabilities or enter into agreements with third parties or related parties to market and sell our product candidates, if they are approved, and as a result, we may be unable to generate product revenues.

We have little to no prior experience in, and currently do not have a commercial infrastructure for, the marketing, sale and distribution of biopharmaceutical products. To achieve commercial success for the product candidates, which we may license to others, we will rely on the assistance and guidance of those collaborators. For product candidates for which we retain commercialization rights and marketing approval, if approved, in order to commercialize our product candidates, we must continue to build out our marketing, sales and distribution capabilities, including a comprehensive healthcare compliance program, or arrange with third parties to perform these services, which will take time and require significant financial expenditures and could delay any product launch and we may not be successful in doing so. There are significant risks involved with building and managing a commercial infrastructure. We, or our collaborators, will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train, manage and retain medical affairs, marketing, sales and commercial support personnel. Recruiting, training and retaining a sales force is expensive and time-consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have incurred these commercialization expenses prematurely or unnecessarily. These efforts may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel. In the event we are unable to develop a commercial infrastructure, we may not be able to commercialize our current or future product candidates, which would limit our ability to generate product revenues. Even if we are able to effectively establish a sales force and develop a marketing and sales infrastructure, our sales force and marketing teams may not be successful in commercializing our current or future product candidates. To the extent we rely on third parties to commercialize any products for which we obtain regulatory approval, we would have less control over their sales efforts and could be held liable if they failed to comply with applicable legal or regulatory requirements.

Table of Contents

If our product candidates do not achieve broad market acceptance, the revenues that we generate from their sales will be limited.

We have not commercialized a product candidate for any indication. Even if our product candidates are approved by the appropriate regulatory authorities for marketing and sale, they may not gain acceptance among physicians, patients, third-party payors and others in the medical community. If any product candidate for which we obtain regulatory approval does not gain an adequate level of market acceptance, we may not generate significant product revenues or become profitable. Market acceptance of our product candidates by the medical community, patients and third-party payors will depend on a number of factors, some of which are beyond our control. For example, physicians are often reluctant to switch their patients, and patients may be reluctant to switch from, existing therapies even when new and potentially more effective or safer treatments enter the market. Efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and may not be successful. Even if the medical community accepts that our product candidates are safe and effective for their approved indications, physicians and patients may not immediately be receptive to such product candidates and may be slow to adopt them as an accepted treatment of the approved indications. If any of our product candidates is approved but does not achieve an adequate level of market acceptance, we may not generate significant revenues and we may not become profitable. The degree of market acceptance of any of our product candidates will depend on a number of factors, including:

•the continued safety and efficacy of our product candidates;

•the prevalence and severity of AEs associated with such product candidates;

•the clinical indications for which the products are approved and the approved claims that we may make for the products;

•limitations or warnings contained in the product’s FDA-approved labeling, including potential limitations or warnings for such products that may be more restrictive than other competitive products or distribution and use restrictions imposed by the FDA with respect to such product candidates or to which we agree as part of a mandatory REMS or voluntary risk management plan;

•changes in the standard of care for the targeted indications for such product candidates;

•the relative difficulty of administration of such product candidates;

•our ability to offer such product candidates for sale at competitive prices, including the cost of treatment versus economic and clinical benefit in relation to alternative treatments or therapies;

•the availability of adequate coverage or reimbursement by third parties, such as insurance companies and other healthcare payors, and by government healthcare programs, including Medicare and Medicaid;

•the extent and strength of our marketing and distribution of such product candidates;

•the safety, efficacy and other potential advantages over, and availability of, alternative treatments already used or that may later be approved for any of our intended indications;

•the timing of market introduction of such product candidates, as well as competitive products;

•the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

•the extent and strength of our third-party manufacturer and supplier support;

•adverse publicity about the product or favorable publicity about competitive products; and

•potential product liability claims.

If any product candidate we commercialize fails to achieve market acceptance, it could have a material and adverse effect on our business, financial condition, results of operations and prospects.

Our product candidates may face competition sooner than anticipated.

The enactment of the Biologics Price Competition and Innovation Act of 2009 (BPCIA) created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, the FDA cannot make an approval of an application for a biosimilar product effective until 12 years after the original branded product was approved under a BLA. Certain changes, however, and supplements to an approved BLA, and subsequent applications filed by the same sponsor, manufacturer, licensor, predecessor in interest or other related entity do not qualify for the 12-year exclusivity period.

Our product candidates may qualify for the BPCIA’s 12-year period of exclusivity. There is a risk that any product candidates we may develop that are approved as a biological product under a BLA would not qualify for the 12-year period of exclusivity or that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider any product candidates we may develop to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Additionally, this period of regulatory exclusivity does not block companies pursuing regulatory approval via their own traditional BLA, rather than via the abbreviated pathway. Even if we receive a period of BPCIA exclusivity for our first licensed product, if subsequent products do not include a modification to the structure of the product that impacts safety, purity, or potency, we may not receive additional periods of exclusivity for those products. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of our reference product candidates in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing. Medicare Part B encourages use of biosimilars by paying the provider the same percentage of the reference product average sale price as a mark-up, regardless of which product is reimbursed. It is also possible that payors will give reimbursement preference to biosimilars even over reference biologics absent a determination of interchangeability.

For our small molecular product candidates, if qualified, the regulatory exclusivity period is less than for our biologic product candidates. The FDCA provides a five-year period of non-patent marketing exclusivity within the U.S. to the first applicant to gain approval of an NDA for a drug where the FDA has not previously approved any other new drug containing the same active molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated NDA or a 505(b)(2) NDA submitted by another company for a generic version of such drug 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. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) 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. As such, we may face competition from generic versions of our small molecule product candidates, which will negatively impact our long-term business prospects and marketing opportunities.

We will need to obtain FDA approval of any proposed branded product names, and any failure or delay associated with such approval may adversely affect our business.

Any name we intend to use for our product candidates in the U.S. will require approval from the FDA regardless of whether we have secured a formal trademark registration from the USPTO. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with other product names. The FDA may also object to a product name if it believes the name inappropriately implies medical claims or contributes to an overstatement of efficacy. If the FDA objects to any of our proposed product names, we may be required to adopt alternative names for our product candidates. If we adopt alternative names, we would lose the benefit of any existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe or otherwise violate the existing rights of third parties, and be acceptable to the FDA. We may be unable to build a successful brand identity for a new product name in a timely manner or at all, which would limit our ability to commercialize our product candidates.

Our internal computer systems, or those used by our CROs, CMOs, clinical sites or other contractors or consultants, may fail or suffer security breaches. A breakdown, cyberattack or information security breach could compromise the confidentiality, integrity and availability of our information technology systems, network-connected control systems and/or our data, interrupt the operation of our business and/or affect our reputation.

We are and will be dependent upon information technology systems, infrastructure and data. In the ordinary course of our business, we will directly or indirectly collect, store and transmit sensitive data, including intellectual property, confidential information, preclinical and clinical trial data, proprietary business information, personal data and personally identifiable health information of our clinical trial subjects and employees, in our data centers and on our networks, or on those of third parties. The secure processing, maintenance and transmission of this information is critical to our operations. The multitude and complexity of our computer systems and those of our CROs, CMOs, clinical sites or other contractors or consultants make them inherently vulnerable to service interruption or destruction, malicious intrusion and random attack. Data privacy or security breaches by third parties, employees, contractors or others may pose a risk that sensitive data, including our intellectual property, trade secrets or personal information of our employees, patients, or other business partners may be exposed to unauthorized persons or to the public. Further, as many of our employees are working remotely, our reliance on our and third-party information technology systems has increased substantially and is expected to continue to increase.

Despite the implementation of security measures, our internal computer systems and those of our CROs, CMOs, clinical sites and other contractors and consultants are vulnerable to failure or damage from computer viruses and other malware, employee error, unauthorized and authorized access or other cybersecurity attacks, natural disasters, terrorism, war, fire and telecommunication and electrical failures. As the cyber-threat landscape evolves, these cyberattacks are increasing in their frequency, sophistication and intensity and are becoming increasingly difficult to detect. The techniques used by cyber criminals change frequently, may not be recognized until launched and can originate from a wide variety of sources, including outside groups such as external service providers, organized crime affiliates, terrorist organizations or hostile foreign governments or agencies. Cyberattacks could include the deployment of harmful malware, denial-of-service, social engineering and other means to affect service reliability and threaten data confidentiality, integrity and availability. While we and our shared services partner, NantWorks, have invested, and continue to invest, in the protection of our data and information technology infrastructure, there can be no assurance that our efforts, or the efforts of our partners, vendors, CROs, CMOs, clinical sites and other contractors and consultants will prevent service interruptions, or identify breaches in our or their systems, that could adversely affect our business and operations and/or result in the loss of critical or sensitive information, which could result in financial, legal, business or reputational harm to us. In addition, our liability insurance may not be sufficient in type or amount to cover us against claims related to security breaches, cyberattacks and other related breaches.

If any such event were to occur and cause interruptions in our operations, it could result in a disruption of our product development programs. For example, the loss of clinical trial data from completed or ongoing clinical trials for a product candidate could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data, or may limit our ability to effectively execute a product recall, if required. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of personal, confidential or proprietary information, we could incur liability and the further development and commercialization of any product candidates could be delayed. Any such event could also result in legal claims or proceedings, liability under laws that protect the privacy of personal information and significant regulatory penalties, and damage to our reputation and a loss of confidence in us and our ability to conduct clinical trials.

Our business could be adversely affected by the effects of health epidemics, pandemics or contagious diseases, including the recent COVID‑19 pandemic and the public and governmental effort to mitigate against the spread of the disease, in regions where we or third parties on which we rely have significant manufacturing facilities, concentrations of clinical trial sites or other business operations, and may have a material adverse effect, on our clinical trials, operations, supply chains, distribution systems, product development, business and results of operations.

Outbreaks of epidemic, pandemic or contagious diseases, such as the ongoing COVID‑19 pandemic, and measures taken in response by governments and businesses worldwide to contain its spread have adversely impacted and may continue to significantly disrupt our operations and adversely affect our business, financial condition and results of operations. Many countries including the U.S. implemented measures such as quarantine, shelter-in-place, curfew, travel and activity restrictions and similar isolation measures, including government orders and other restrictions on the conduct of business operations. The continued spread of this pandemic has caused significant volatility and uncertainty in the U.S. and international markets and has resulted in increased risks to our operations. The COVID‑19 pandemic and any actions we have taken in response, are affecting and could materially affect our operations, including at our headquarters and at our manufacturing facilities, which have been and may in the future be subject to state executive orders and shelter-in-place orders, and at our clinical trial sites, as well as the business or operations of our CROs, CMOs, clinical sites or other third parties with whom we conduct business. Any such epidemic or pandemic may heighten the risk that a significant portion of our workforce could suffer illness or otherwise not be permitted or be unable to work, and may require that certain of our employees work remotely, which heightens certain risks, including but not limited to, those associated with an increased demand for information technology resources, increased risk of cybersecurity attacks (including social engineering attacks), risks related to internal controls and increased risk of unauthorized dissemination of sensitive personal information or our proprietary or confidential information.

The rapid development and fluidity of the pandemic preclude any prediction as to the ultimate effect of COVID-19 on us. While the U.S. and other countries have begun or will begin to reopen their economies, the extent to which COVID-19 will impact our future operations will depend on many factors which cannot be predicted with confidence, including the duration of the outbreak. Any resurgence in COVID-19 infections could result in the imposition of new mandates and prolonged restrictive measures implemented in order to control the spread of the disease.

U.S. President Biden has issued an Executive Order requiring federal employees and covered contractors to be vaccinated against COVID-19. Additionally, on November 4, 2021, the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) issued a COVID-19 Vaccination and Testing Emergency Temporary Standard requiring all employers with 100 or more employees to ensure that their employees are fully vaccinated or tested for COVID-19 on at least a weekly basis. On January 20, 2022, The U.S. Supreme Court invalidated this requirement. However additional vaccine and testing mandates may be announced in other jurisdictions in which we operate our business. While it is not currently possible to predict with any certainty the exact impact the new regulations would have on us and our suppliers, the implementation of such government mandated vaccination or testing mandates may impact our ability to retain current employees and attract new employees and result in labor disruptions.

We are monitoring a number of risks related to this pandemic, including the following:

•Financial: We expect to continue spending on research and development during the year ending December 31, 2022 and beyond, and we could also have unexpected expenses related to the pandemic. The short-term continued expenses, as well as the overall uncertainty and disruption caused by the pandemic, will likely cause a delay in our ability to commercialize a product and adversely impact our financial results.

•Manufacturing: The pandemic has impacted, and may continue to impact, our manufacturing locations, including through the effects of facility closures, reductions in operating hours and other social distancing efforts.

•Supply Chain: As the pandemic continues to progress, it has resulted and could continue to result in significant disruptions in our respective supply chains and distribution channels in the future. In addition, there may be unfavorable changes in the availability or cost of raw materials, intermediates and other materials necessary for production, which may result in disruptions in our supply chain and adversely affect our ability to have manufactured certain product candidates for clinical supply.

•Clinical Trials: This pandemic may adversely affect certain of our clinical trials, including our ability to initiate and complete our clinical trials within the anticipated timelines. Due to site and participant availability during the pandemic, new subject enrollment has slowed and is expected to continue to slow, at least in the short-term, for most of our clinical trials. For ongoing trials, we have seen, and expect to continue to see an increasing number of clinical trial sites imposing restrictions on patient visits to limit risks of possible COVID‑19 exposure, and we may experience issues with participant compliance with clinical trial protocols as a result of quarantines, travel restrictions and interruptions to healthcare services. The current pressures on medical systems and the prioritization of healthcare resources toward the COVID‑19 pandemic have also resulted, and may continue to result, in interruptions in data collection and submissions for certain clinical trials and delayed starts for certain planned studies. As a result, our anticipated filing and marketing timelines may be adversely impacted.

•Overall Economic and Capital Markets Environment: The continued spread of COVID‑19 has led to and could continue to lead to severe disruption and volatility in the U.S. and global capital markets, which could result in a decline in stock price, high inflation, increase our cost of capital and adversely affect our ability to access the capital markets in the future even after local conditions improve. In addition, trading prices on the public stock market have been highly volatile as a result of the COVID‑19 pandemic.

•Regulatory Reviews: The operations of the FDA or other regulatory agencies may be adversely affected. The legislative and regulatory environment governing our businesses is dynamic and changing frequently in response to COVID‑19. In response to COVID‑19, federal, state and local governments are issuing new rules, regulations, orders and advisories on a regular basis. These government actions can impact us, our members and our suppliers. There is also the possibility that we may experience delays with obtaining approvals for our IND applications, BLAs, and/or NDAs. The pandemic may also result in greater regulatory uncertainty.

Risks Related to Reliance on Third Parties

We have limited experience conducting clinical trials and have relied and will rely on third parties and related parties to conduct many of our preclinical studies and clinical trials, to manufacture products and to perform many essential services for any products that we commercialize, including services related to distribution, government price reporting, customer service, accounts receivable management, cash collection and adverse event reporting. Any failure by a third party, related party, or by us to perform as expected, to comply with legal and regulatory requirements or to conduct the clinical trials according to GCP regulations, and in a timely manner, may delay or prevent our ability to seek or obtain regulatory approval for or commercialization of our product candidates and our ability to commercialize our current or future product candidates will be significantly impacted and we may be subject to regulatory sanctions.

Large-scale clinical trials require significant financial and management resources. We expect to be heavily reliant on third and related parties, including medical institutions, academic institutions, clinical investigators or contract research organizations (CROs) to conduct, supervise or monitor some or all aspects of our clinical trials, and in some cases, CMOs to manufacture products, which may force us to encounter delays and challenges that are outside of our control. Nevertheless, we are responsible for ensuring that each of our trials is conducted in accordance with the applicable trial protocol and legal, regulatory and scientific standards, and our reliance on CROs, clinical trial sites, and other third parties does not relieve us of these responsibilities. Our CROs and other third parties must communicate and coordinate with one another in order for our trials to be successful. We have a limited history of conducting clinical trials and have no experience as a company in filing and supporting the applications necessary to gain marketing approvals. Our relative lack of experience conducting clinical trials may contribute to our planned clinical trials not beginning or completing on time, if at all. Securing marketing approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities and clinical trial sites by, applicable regulatory authorities.

For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial and for ensuring that our preclinical studies are conducted in accordance with Good Laboratory Practice (GLP) regulations, as appropriate. Moreover, the FDA and comparable foreign regulatory authorities require us and the third parties upon which we intend to rely for conducting our clinical trials to comply with GCP for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected. Regulatory authorities enforce these requirements through periodic inspections (including pre-approval inspections once a BLA or NDA is filed with the FDA) of trial sponsors, clinical investigators, trial sites and certain third parties including CMOs. If we, our CROs, clinical trial sites, or other third parties fail to comply with applicable GCP or other regulatory requirements, we or they may be subject to enforcement or other legal actions, the clinical data generated in our clinical trials may be deemed unreliable and have to be repeated, and our submission of marketing applications may be delayed or the FDA 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.

We rely on third parties to manufacture, package, label and ship some of our product candidates for the clinical trials that we conduct. Any performance failure on the part of these third parties could delay clinical development or marketing approval of our product candidates or commercialization of our product candidates, if approved, producing additional losses and depriving us of potential product revenues.

Table of Contents

Our CROs, clinical trial sites and other third parties may also have relationships with other entities, some of which may be our competitors, for whom they may also be conducting clinical trials or other therapeutic development activities that could harm our competitive position. In addition, these third parties are not our employees, and except for remedies available to us under our agreements with them, we cannot control whether or not they devote sufficient time and resources to our ongoing clinical and preclinical programs. If these third parties conducting our clinical trials (i) do not successfully carry out their contractual duties, (ii) do not meet expected deadlines, (iii) experience work stoppages, (iv) do not conduct our clinical trials in accordance with regulatory requirements or our stated protocols, (v) need to be replaced, (vi) experience financial hardships or (vii) terminate their agreements with us or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our clinical trial protocols, GCP or other regulatory requirements or for other reasons, our trials may need to be repeated, extended, delayed or terminated, we may not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates, we will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates or we or they may be subject to regulatory enforcement actions. Additionally, we may need to conduct additional clinical trials or enter into new arrangements with alternative CROs, clinical investigators or other third parties, which we may not be able to do on commercially reasonable terms, or at all and which may involve additional cost and time and require management time and focus. As a result, delays could occur, which could compromise our ability to meet our desired development timelines. Furthermore, if any of the third parties conducting our clinical trials experience any financial hardships due to difficulties relating to the operation of their business, it could damage our business, financial condition, results of operations and prospects. In addition, if an agreement with any of our collaborators terminates, our access to technology and intellectual property licensed to us by that collaborator may be restricted or terminate entirely, which may delay the continued development of our product candidates using the collaborator’s technology or intellectual property or require us to stop development of those product candidates completely. 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. To the extent we are unable to successfully identify and manage the performance of third-party service providers in the future, our business may be materially and adversely affected.

We expect to retain third-party service providers to perform a variety of functions related to the sale of our current or future product candidates, key aspects of which will be out of our direct control. These service providers may provide key services related to distribution, customer service, accounts receivable management, and cash collection. If we retain a service provider, we would substantially rely on it as well as other third-party providers that perform services for us, including entrusting our inventories of products to their care and handling. If these third-party service providers fail to comply with applicable laws and regulations, fail to meet expected deadlines or otherwise do not carry out their contractual duties to us, or encounter physical or natural damage at their facilities, our ability to deliver product to meet commercial demand would be significantly impaired and we may be subject to regulatory enforcement action.

In addition, we may engage in the future with third parties to perform various other services for us relating to AE reporting, safety database management, fulfillment of requests for medical information regarding our product candidates and related services. If the quality or accuracy of the data maintained by these service providers is insufficient, or these third parties otherwise fail to comply with regulatory requirements related to AE reporting, we could be subject to regulatory sanctions.

Additionally, we may contract in the future with a third party to calculate and report pricing information mandated by various government programs. If a third party fails to timely report or adjust prices as required or errs in calculating government pricing information from transactional data in our financial records, it could impact our discount and rebate liability, and potentially subject us to regulatory sanctions or FCA lawsuits.

Our reliance on third and related parties can also present intellectual property-related risks. For example, collaborators may not properly obtain, maintain, enforce or defend intellectual property or proprietary rights relating to our product candidates or technology or may use our proprietary information in such a way as to expose us to potential litigation or other intellectual property-related proceedings, including proceedings challenging the scope, ownership, validity and enforceability of our intellectual property. Collaborators may also own or co-own intellectual property covering our product candidates or technology that results from our collaboration with them, and in such cases, we may not have the exclusive right to commercialize such intellectual property or such product candidates or technology. Collaborators may also gain access to our trade secrets or formulations and impact our ability to commercialize proprietary technology. We may also need the cooperation of our collaborators to enforce or defend any intellectual property we contribute to or that arises out of our collaborations, which may not be provided to us.

We also anticipate that part of our strategy for pursuing the wide range of indications potentially addressed by Anktiva will involve further investigator-initiated clinical trials. While these trials generally provide us with valuable clinical data that can inform our future development strategy, we generally have less control over not only the conduct but also the design of these clinical trials. Third-party investigators may design clinical trials involving our product candidates with clinical endpoints that are more difficult to achieve or in other ways that increase the risk of negative clinical trial results compared to clinical trials we may design on our own. Negative results from investigator-initiated clinical trials, regardless of how the clinical trial was designed or conducted, could have a material adverse effect on our business and the perception of our product candidates.

Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services.

We use the Clinic, a related party, in some of our clinical trials which may expose us to significant regulatory risks. If our data for this site is not sufficiently robust or if there are any data integrity issues, we may be required to repeat such studies or required to contract with other clinical trial sites, and our clinical development plans will be significantly delayed, and we will incur additional costs.

The Clinic has conducted, is currently conducting, and in the future may conduct, clinical trials involving our product candidates. The Clinic is a related party as it is owned by an officer of the company and additionally, NantWorks, LLC (NantWorks) manages the administrative operations of the Clinic. Prior to June 30, 2019, one of the company’s officers was an investigator or sub-investigator for certain of the company’s trials conducted at the Clinic. NantWorks, which is wholly owned by our Executive Chairman and Global Chief Scientific and Medical Officer, Dr. Soon‑Shiong, provides certain administrative services (and has loaned money) to the Clinic. Under certain circumstances, we may be required to report some of these relationships to the FDA. Relying on a related party clinical site to develop data that is used as the basis to support regulatory approval can expose us to significant regulatory risks. The FDA may conclude that a financial relationship between us, the Clinic and/or a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA or comparable regulatory authorities may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. If any data integrity, or regulatory non-compliance issues occur during the study, we may not be able to use the data for our regulatory approval. This could result in a delay in approval, or rejection, of our marketing applications by the FDA and may ultimately lead to the denial of regulatory approval of one or more of our product candidates.

We have formed, and may in the future form or seek, strategic alliances or enter into collaborations with third parties or additional licensing arrangements in the future, and we may not realize the benefits of such alliances or licensing arrangements. If we fail to enter into such strategic alliances, collaborations or licensing arrangements, or such strategic alliances, collaborations or licensing arrangements are not successful, we may not be able to capitalize on the market potential of our product candidates.

We have formed, and may in the future form or seek, strategic alliances, create joint ventures or collaborations or enter into additional licensing arrangements with third and related parties that we believe will complement or augment our development and commercialization efforts with respect to our product candidates and any future product candidates that we may develop. For example, we have entered into an agreement whereby Viracta Therapeutics, Inc. (Viracta) granted to us exclusive world-wide rights to Viracta’s Phase 2 drug candidate, VRx-3996, for use in combination with our platform of NK cell therapies. However, if Viracta fails to raise sufficient capital to complete their Phase 2 trial, if their trial is unsuccessful, or if our future clinical trial of NK cell therapy in combination with VRx-3996 fails, the value of the Viracta license would be adversely affected. We plan to collaborate with governmental, academic and corporate partners, including affiliates, to improve and develop Anktiva, saRNA, hAd5 and yeast technologies, and other therapies for new indications for use in combination with other therapies and to improve and develop other product candidates, which may expose us to additional risks, or we may not realize the benefits of such collaborations.

Because some of our collaborations are conducted at outside laboratories, and we do not have complete control over how the studies are conducted or reported or over the manufacturing methods used to manufacture our Anktiva product candidate, the results of such studies, which we may use as the basis for our conclusions, projections or decisions with respect to our current or future product candidates, may be incorrect or unreliable, or may have a negative impact on us if the results of such studies are imputed to our product candidates or proposed indications, even if such imputation is improper. Additionally, we may use third-party data to analyze, reach conclusions or make predictions or decisions with respect to our product candidates that may be incomplete, inaccurate or otherwise unreliable.

Further, collaborations involving our product candidates will be subject to numerous risks, which may include the following:

•collaborators, including their related or affiliated companies, may be entitled to receive exclusive rights for or involving our products;

•collaborators have significant discretion in determining the efforts and resources that they will apply to a collaboration;

•collaborators may not pursue development and commercialization of our product candidates or may elect not to continue or renew development or commercialization of our product candidates based on clinical trial results, changes in their strategic focus due to the acquisition of competitive products, availability of funding or other external factors, such as a business combination that diverts resources or creates competing priorities;

•collaborators may delay clinical trials, provide insufficient funding for a clinical trial, stop a clinical trial, abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;

•collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates;

•a collaborator with marketing and distribution rights to one or more products may not commit sufficient resources to their marketing and distribution;

•collaborators may not properly maintain, defend or enforce our intellectual property rights or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability;

Table of Contents

•disputes may arise between us and a collaborator that cause the delay or termination of the research, development or commercialization of our product candidates, or that result in costly litigation or arbitration that diverts management attention and resources;

•collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable product candidates;

•if an agreement with any collaborator terminates, our access to technology and intellectual property licensed to us by that collaborator may be restricted or terminate entirely, which may delay our continued development of our product candidates using the collaborator’s technology or intellectual property or require us to stop development of those product candidates completely; and

•collaborators may own or co-own intellectual property covering our product candidates or technology that results from our collaborating with them, and in such cases, we may not have the exclusive right to commercialize such intellectual property.

As a result, if we enter into collaboration agreements and strategic partnerships or license our product candidates, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture, which could delay our timelines or otherwise adversely affect our business. Additionally, exclusive rights that we may grant in connection with collaboration agreements may limit our ability to enter into new or additional collaboration agreements or strategic partnerships if we experience issues with existing collaborations. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenues or specific net income that justifies such transaction. Any delays in entering into new collaborations or strategic partnership agreements related to our product candidates could delay the development and commercialization of our product candidates in certain geographies for certain indications, which would harm our business prospects, financial condition and results of operations.

Any of these relationships may require us to incur non-recurring and other charges, increase our near and long-term expenditures, issue securities that dilute our existing stockholders or disrupt our management and business. In addition, we face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our product candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view our product candidates as having the requisite potential to demonstrate safety and efficacy.

If conflicts arise between us and our collaborators or strategic partners, these parties may act in a manner adverse to us and could limit our ability to implement our strategies.

If conflicts arise between our corporate or academic collaborators or strategic partners and us, the other party may act in a manner adverse to us and could limit our ability to implement our strategies. Some of our existing academic collaborators and strategic partners are conducting multiple product development efforts. Such current or future collaborators or strategic partners could become our competitors in the future and could develop competing products, preclude us from entering into collaborations with their competitors, fail to obtain timely regulatory approvals, terminate their agreements with us prematurely or fail to devote sufficient resources to the development and commercialization of our product candidates. Competing product candidates, either developed by the collaborators or strategic partners or to which the collaborators or strategic partners have rights, may result in the withdrawal of our collaborator’s or partner’s support for our product candidates.

For example, in 2019, Sorrento Therapeutics, Inc. (Sorrento) with which we jointly established a new entity called Immunotherapy NANTibody, LLC (NANTibody) as a stand-alone biotechnology company, commenced litigation against us and certain of our officers and directors, alleging that we improperly caused NANTibody to acquire IgDraSol, Inc. and in 2020, Sorrento sent letters purporting to terminate an exclusive license agreement with us and an exclusive license agreement with NANTibody. Additionally, in 2020, we received a Request for Arbitration before the International Chamber of Commerce, International Court of Arbitration, served by Shenzhen Beike Biotechnology Co. Ltd. asserting breach of contract under our subsidiary Altor’s license agreement with them. For more information regarding these disputes, see Note 7, Commitments and Contingencies—Litigation, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. Any of these developments could harm our product development efforts.

Table of Contents

We will be heavily dependent on our senior management, particularly Dr. Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer, and a loss of a member of our senior management team in the future, even if only temporary, could harm our business.

Our operations will be dependent upon the services of our executives and our employees who are engaged in research and development. If we lose the services of members of our senior management, particularly Dr. Soon-Shiong, for a short or an extended time, for any reason, we may not be able to find appropriate replacements on a timely basis, and our business, financial condition and results of operations could be materially adversely affected. Our existing operations and our future development depend to a significant extent upon the performance and active participation of certain key individuals, particularly Dr. Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer. Although Dr. Soon-Shiong focuses heavily on our matters and is highly active in our management, he does devote a significant amount of his time to a number of different endeavors and companies, including NantHealth, Inc., NantMedia Holdings, LLC (which operates the Los Angeles Times and the San Diego Union-Tribune) and NantWorks, which is a collection of multiple companies in the healthcare and technology space. The risks related to our dependence upon Dr. Soon-Shiong are particularly acute given his ownership percentage, the commercial and other relationships that we have with entities affiliated with him, his role in our company and his public reputation. We may also be dependent on additional funding from Dr. Soon-Shiong and his affiliates, which may not be available when needed and which he is under no obligation to provide.

To induce valuable employees to remain at our company, in addition to salary and cash incentives, we have provided, and plan to continue providing, equity incentive awards that vest over time. The value to employees of equity incentive awards that vest over time may be significantly affected by movements in our stock price that are beyond our control and may at any time be insufficient to counteract more lucrative offers from other companies. Despite our efforts to retain valuable employees, members of our management, scientific and development teams may terminate their employment with us on short notice. We do not have employment agreements with our key employees and all of our employees are hired on an “at-will” basis, which means that any of our employees could leave our employment at any time, with or without notice. We do not maintain “key man” insurance policies on the lives of these individuals or the lives of any of our other employees.

We will need to grow the size and capabilities of our organization, and we may experience difficulties in managing this growth.

Our future financial performance and our ability to commercialize our product candidates will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of their attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities. In order to develop our business in accordance with our business plan, we will have to hire additional qualified personnel, including in the areas of research, manufacturing, clinical trials management, regulatory affairs, and sales and marketing. We are continuing our efforts to recruit and hire the necessary employees to support our planned operations in the near term. However, competition for qualified personnel in the biotechnology and pharmaceuticals industry is intense due to the limited number of individuals who possess the skills and experience required, and no assurance can be given that we will be able attract, hire, retain and motivate the highly skilled employees that we need, on acceptable terms or at all. Future growth will impose significant added responsibilities on members of management, including:

•identifying, recruiting, integrating, maintaining, and motivating additional employees;

•managing our internal development efforts effectively, including the clinical and FDA review process for our product candidates, while complying with our contractual obligations to contractors and other third parties; and

•improving our operational, financial and management controls, reporting systems, and procedures.

We currently rely, and for the foreseeable future we expect to rely, in substantial part on certain independent organizations, advisors and consultants to provide certain services. There can be no assurance that the services of these independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements on economically reasonable terms, or at all. In addition, if we are unable to effectively manage our outsourced activities or if the quality, compliance or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed, or terminated, and we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business.

Table of Contents

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize our product candidates and, accordingly, may not achieve our research, development, and commercialization goals on a timely basis, or at all.

If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute our stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks.

We may evaluate various acquisitions and strategic partnerships, including licensing or acquiring complementary products, intellectual property rights, technologies, or businesses. Any potential acquisition or strategic partnership may entail numerous risks, including:

•assimilation of operations, intellectual property, and products of an acquired company or product, including difficulties associated with integrating new personnel;

•the diversion of our managements’ attention from our existing product programs and initiatives in pursuing such a strategic merger or acquisition;

•retention of key employees, the loss of key personnel, and uncertainties in our ability to maintain key business relationships;

•risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and their existing products or product candidates and regulatory approvals; and

•our inability to generate revenues from acquired technology and/or products sufficient to meet our objectives in undertaking the acquisition or even to offset the associated acquisition and maintenance costs.

Depending on the size and nature of future strategic acquisitions, we may acquire assets or businesses that require us to raise additional capital or to operate or manage businesses in which we have limited experience. Making larger acquisitions that require us to raise additional capital to fund the acquisition will expose us to the risks associated with capital raising activities. Acquiring and thereafter operating larger new businesses will also increase our management, operating and reporting costs and burdens (including increased cash requirements). In addition, if we undertake acquisitions, we may issue dilutive equity securities, assume or incur additional debt obligations or contingent liabilities, incur large one-time expenses and acquire intangible assets that could result in significant future amortization expense. Moreover, we may not be able to locate suitable acquisition opportunities and this inability could impair our ability to grow or obtain access to technology or products that may be important to the development of our business.

We may become involved in securities litigation or stockholder derivative litigation in connection with our recent Merger, and this could divert the attention of our management and harm our business, and insurance coverage may not be sufficient to cover all related costs and damages.

Securities litigation or stockholder derivative litigation frequently follows the announcement of certain significant business transactions, such as the sale of a business division or announcement of a business combination transaction. We are involved in this type of litigation in connection with our recent Merger, and we may become involved in this type of litigation in the future. Litigation often is expensive and diverts management’s attention and resources, which could adversely affect our business and the company.

Table of Contents

A variety of risks associated with marketing our product candidates internationally could materially adversely affect our business.

We plan to seek regulatory approval of our product candidates outside of the U.S. and, accordingly, we expect that we will be subject to additional risks related to operating in foreign countries if we obtain the necessary approvals, including:

•differing regulatory requirements in foreign countries;

•unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements;

•economic weakness, including inflation, or political instability in particular foreign economies and markets;

•compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

•foreign taxes, including withholding of payroll taxes;

•foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations incident to doing business in another country;

•difficulties staffing and managing foreign operations;

•workforce uncertainty in countries where labor unrest is more common than in the U.S.;

•differing payor reimbursement regimes, governmental payors or patient self-pay systems, and price controls;

•potential liability under the FCPA or comparable foreign regulations;

•challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect intellectual property rights to the same extent as the U.S.;

•production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad;

•the impact of public health epidemics on the global economy, such as the coronavirus pandemic currently having an impact throughout the world; and

•business interruptions resulting from geo-political actions, including war and terrorism.

These and other risks associated with international operations may materially adversely affect our ability to attain or maintain profitable operations.

We are party to a public-private partnership regarding our manufacturing facility in Dunkirk, New York, and if we or our counterparties fail to meet the obligations of those agreements, it could materially impact our development, operations and prospects.

We paid approximately $40.0 million to Athenex, and the leasehold interest in the Dunkirk Facility was transferred to us. Our annual lease payment will be $2.00 per year for an initial 10-year term, with an option to renew the lease under substantially the same terms and conditions for an additional 10-year term. As part of the transaction, we assumed obligations under various third-party agreements, and committed to spend $1.52 billion on operational expenses during the initial term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. We also committed to hiring 450 employees at the Dunkirk Facility within the first five years of operations, with 300 such employees to be hired within the first 2.5 years of operation. We are eligible for certain sales-tax exemption savings during the development of the Dunkirk Facility, and certain property tax savings over the next 20 years, subject to certain terms and conditions, including performance of certain of the obligations described above.

Table of Contents

Failure to satisfy the obligations over the lease term, including the milestones we have committed to achieve, may give rise to certain rights and remedies of the lessor and other governmental authorities including, for example, termination of the lease agreement and other related agreements and potential recoupment of a percentage of the grant funding and other benefits received, subject to the terms and conditions of the applicable agreements. If we lose access to the Dunkirk Facility and related leased equipment, it could disrupt our operations and manufacturing activities, cause us to divert resources to finding alternative facilities, which would not have any subsidies, and could have a significant impact on our operations and financial performance. We may also be subject to lawsuits or claims for damages against us if we are unable to comply with our obligations under these arrangements, which could materially and adversely affect our business, results of operations and financial condition. Furthermore, there is no guarantee that the counterparties to our public-private partnerships will comply with the terms of the agreements, including that their ability to fund their capital commitments under the agreements may be subject to their ability to raise additional capital and that further construction or operational timetables may not be met. Public-private partnerships are also subject to risks associated with government and government agency counterparties, including risks related to government relations compliance, sovereign immunity, shifts in the political environment, changing economic and legal conditions and social dynamics.

Risks Related to Healthcare and Other Government Regulations

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, unable to commercialize our product candidates. We are, and if we receive regulatory approval of our product candidates, will continue to be subject to ongoing extensive regulation, regulatory obligations and continued regulatory review, which may result in significant additional expense.

Our product candidates are subject to extensive governmental regulations relating to, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring and post-approval reporting of drugs and therapeutic biologics. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required to be successfully completed in the U.S. and in many foreign jurisdictions before a new drug or therapeutic biologic can be marketed. Satisfaction of these and other regulatory requirements is costly, lengthy, time-consuming, uncertain and subject to unanticipated delays and can vary substantially based upon the type, complexity and novelty of the products involved. We have not previously submitted a BLA or NDA or similar marketing or drug approval application to the FDA or comparable foreign authorities, for any product candidate, and we may never receive such regulatory approval for any of our product candidates or regulatory approval that will allow us to successfully commercialize our product candidates. In addition, regulatory agencies may lack experience with our technologies and products, which may lengthen the regulatory review process, increase our development costs and delay or prevent their commercialization.

Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional preclinical studies, clinical trials or other research. The number and types of preclinical studies and clinical trials that will be required for regulatory approval also vary depending on the product candidate, the disease or condition that the product candidate is designed to address and the regulations applicable to any particular product candidate. Approval policies, 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 and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates.

Any delay in completing development or obtaining, or failing to obtain, required approvals would have a material and adverse effect on our ability to generate revenue from the particular product candidate for which we are developing and seeking approval. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, be subject to other regulatory enforcement action, and we may not achieve or sustain profitability.

Table of Contents

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

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, however a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. Approval policies, procedures and requirements may vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the U.S., including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. In many jurisdictions outside the U.S., 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 product candidates is also subject to approval.

Obtaining foreign regulatory approvals and establishing and maintaining compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our product candidates in certain countries. If we fail to comply with the regulatory requirements in international markets and/or fail to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.

If we fail to comply with U.S. and foreign regulatory requirements, regulatory authorities could limit or withdraw any marketing or commercialization approvals we may receive and subject us to other penalties that could materially harm our business. For example, our GMP-in-a-Box will be regulated by the FDA as a medical device, and regulatory compliance for medical devices is expensive, complex and uncertain, and a failure to comply could lead to enforcement actions against us and other negative consequences for our business.

The FDA and similar agencies regulate medical devices. All of our potential medical device products and material modifications will be subject to extensive regulation and clearance or approval from the FDA and non-U.S. regulatory agencies prior to commercial sale and distribution as well as after clearance or approval. Complying with these regulations is costly, time-consuming, complex and uncertain. For instance, before a new medical device, or a new intended use for an existing device, can be marketed in the U.S., a company must first submit and receive either 510(k) clearance or pre-marketing approval from the FDA, unless an exemption applies.

Any regulatory approvals that we receive for our product candidates will require surveillance to monitor the safety and efficacy of the product candidate. The FDA and similar agencies have significant pre- and post-market authority, including requirements related to product design, development, testing, laboratory and clinical trials and preclinical studies approval, manufacturing processes and quality (including suppliers), labeling, packaging, distribution, AE and deviation reporting, storage, shipping, pre-market clearance or approval, advertising, marketing, promotion, sale, import, export, product change, recalls, submissions of safety and effectiveness, post-market surveillance and reporting of deaths or serious injuries and certain malfunctions, and other post-marketing information and reports such as deviation reports, registration, product listing, annual user fees, and recordkeeping for our product candidates. The FDA may also require a REMS to approve our product candidates, which may impose further requirements or restrictions on the distribution or use of an approved drug or therapeutic biologic. The FDA may also require post-approval Phase 4 trials. Moreover, the FDA and comparable foreign regulatory authorities will continue to closely monitor the safety profile of any product even after approval.

Medical devices regulated by the FDA are subject to general controls which include: registration with the FDA; listing commercially distributed products with the FDA; complying with cGMP under Quality Systems Regulations; filing reports with the FDA of and keeping records relative to certain types of AEs associated with devices under the medical device reporting regulation; assuring that device labeling complies with device labeling requirements; reporting certain device field removals and corrections to the FDA; and obtaining pre-market notification 510(k) clearance for devices prior to marketing. Some devices known as 510(k)-exempt devices can be marketed without prior marketing-clearance or approval from the FDA. In addition to the general controls, some Class 2 medical devices are also subject to special controls, including adherence to a particular guidance document and compliance with the performance standard. Instead of obtaining 510(k) clearance, most Class 3 devices are subject to PMA.

Table of Contents

The FDA can also refuse to clear or approve pre-market applications for any medical device we develop. We may not be able to obtain the necessary clearances or approvals or may be unduly delayed in doing so, for any medical device products we develop, which could harm our business. Furthermore, even if we are granted regulatory clearances or approvals for any medical device products, they may include significant limitations on the indicated uses for the product, which may limit the market for the product.

In addition, we, our contractors, and our collaborators are and will remain responsible for FDA compliance. We and any of our collaborators, including our contract manufacturers, could be subject to periodic unannounced inspections by the FDA to monitor and ensure compliance with regulatory requirements. Application holders must further notify the FDA, and depending on the nature of the change, obtain FDA pre-approval for product and manufacturing changes. The cost of compliance with post-approval regulations may have a negative effect on our operating results and financial condition.

If the FDA or comparable foreign regulatory authorities become aware of new safety information or previously unknown problems after approval of any of our product candidates, including: (i) AEs of unanticipated severity or frequency, (ii) that the product is less effective than previously thought, (iii) problems with our third-party manufacturers or manufacturing processes, or (iv) failure to comply with regulatory requirements, or if we violate regulatory requirements at any stage, whether before or after marketing approval is obtained, we may face a number of regulatory consequences, including fines, warnings or untitled letters, holds on clinical trials, delay of approval or refusal by the FDA to approve pending applications or supplements to approved applications, suspension or withdrawal of regulatory approval, product recalls and seizures, administrative detention of products, refusal to permit the import or export of products, operating restrictions or partial suspension or total shutdown of production, injunctions, consent decrees, civil penalties and criminal prosecution, among other consequences. Additionally, we may face unanticipated expenditures to address or defend such actions and customer notifications for repair, replacement or refunds. Any such restrictions could limit sales of the product. Any of these events could further have other material and adverse effects on our operations and business and could adversely impact our stock price and could significantly harm our business, financial condition, results of operations, and prospects.

The FDA also regulates the advertising and promotion of medical devices to ensure that the claims are consistent with their regulatory clearances or approvals, that there are adequate and reasonable data to substantiate the claims and that the promotional labeling and advertising is neither false nor misleading in any respect. If the FDA determines that any of our advertising or promotional claims are misleading, not substantiated or not permissible, we may be subject to enforcement actions, including warning letters, and we may be required to revise our promotional claims and make other corrections or restitutions. Failure to comply with applicable U.S. requirements regarding, for example, promoting, manufacturing, or labeling our medical device products, may subject us to a variety of administrative or judicial actions and sanctions, such as Form 483 observations, warning letters, untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties and criminal prosecution. If any of our medical device products cause or contribute to a death or a serious injury or malfunction in certain ways, we will be required to report under applicable medical device reporting regulations, which can result in voluntary corrective actions or agency enforcement actions.

If any of these events were to occur, it would have a material and adverse effect on our business, financial condition and results of operations.

Results for any patient who receives compassionate use access to our product candidates should not be viewed as representative of how the product candidate will perform in a well-controlled clinical trial, and cannot be used to establish safety or efficacy for regulatory approval.

We often receive requests for compassionate use access to our investigational drugs by patients that do not meet the entry criteria for enrollment into our clinical trials. Generally, patients requesting compassionate use have no other treatment alternatives for life threatening conditions. We evaluate each compassionate use request on an individual basis, and in some cases grant access to our investigational product candidates outside of our sponsored clinical trials if a physician certifies that the patient receiving treatment is critically ill and does not meet the entry criteria for one of our open clinical trials. Individual patient results from compassionate use access may not be used to support submission of a regulatory application, may not support approval of a product candidate and should not be considered to be indicative of results from any on-going or future well-controlled clinical trial. Before we can seek regulatory approval for any of our product candidates, we must demonstrate in well-controlled clinical trials statistically significant evidence that the product candidate is both safe and effective for the indication we are seeking approval. The results of our compassionate use program may not be used to establish safety or efficacy or regulatory approval.

We are and will be subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws and anti-money laundering laws and regulations. Compliance with these legal standards could impair our ability to compete in domestic and international markets. We can face criminal and/or civil liability and other serious consequences for violations, which can harm our business.

Our product candidates will be subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls, the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. §201, the U.S. Travel Act, the USA PATRIOT Act and possibly other state and national anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We use CROs abroad for clinical trials. In addition, we may engage third-party intermediaries to sell our product candidates and solutions abroad once we enter a commercialization phase for our product candidates and/or to obtain necessary permits, licenses, and other regulatory approvals. We or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and agents, even if we do not explicitly authorize or have actual knowledge of such activities. if we fail to comply with these laws and regulations, we and certain of our employees could be subject to substantial civil or criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm and other consequences.

We have adopted an anti-corruption policy, which mandates compliance with the FCPA and other anti-corruption laws applicable to our business throughout the world. However, there can be no assurance that our employees and third-party intermediaries will comply with this policy or such anti-corruption laws. Non-compliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other investigations, or other enforcement actions. If such actions are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor, which can result in added costs and administrative burdens.

Our failure to comply with state, national and/or international data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and adversely impact our operating results.

There are numerous laws and legislative and regulatory initiatives at the federal and state levels addressing privacy and security concerns, and some state privacy laws apply more broadly than the Health Insurance Portability and Accountability Act (HIPAA) and associated regulations. For example, California recently enacted legislation—the California Consumer Privacy Act of 2018 (CCPA)—which went into effect on January 1, 2020. The CCPA, among other things, creates new data privacy and security obligations for covered companies and provides new privacy rights to California consumers, including the right to opt out of certain disclosures of their information. The CCPA also provides for civil penalties as well as a private right of action with statutory damages for certain data breaches, thereby potentially increasing risks associated with a data breach. Although the law includes limited exceptions, including for certain information collected as part of clinical trials as specified in the law, it may regulate or impact our processing of personal information depending on the context. Additionally, a new privacy law, the California Privacy Rights Act (CPRA), was approved by California voters in November 2020 and goes into effect in most material respects on January 1, 2023. The CPRA significantly modified the CCPA, which may require us to modify our practices and policies and may further increase our compliance costs and potential liability. Certain other state laws impose similar privacy obligations, and all 50 states have laws including obligations to provide notification of security breaches of computer databases that contain personal information to affected individuals, state officers and others. For example, the CCPA has prompted the enactment of several new state laws or amendments of existing state laws, such as in New York, Nevada, Virginia, and Colorado. These laws could mark the beginning of a trend toward more stringent privacy legislation in other U.S. states and have prompted a number of proposals for new federal and state-level privacy legislation. To the extent these state laws as well as other federal and state privacy laws, including new laws and changes in existing laws, apply to our business and operations, our compliance costs and potential liability with respect to personal information we collect could expose us to great liability and increase compliance costs.

There are also various laws and regulations in other jurisdictions relating to privacy and security. For example, European Union (EU) member states and other foreign jurisdictions, including Switzerland, have adopted data protection laws and regulations which impose significant compliance obligations on us. The collection and use of health data in the EU is governed by the EU General Data Protection Regulation (GDPR). The GDPR, which is wide-ranging in scope and applies extraterritorially, imposes several requirements relating to the consent of the individuals to whom the personal data relates, the information provided to such individuals, the security and confidentiality of the personal data, data breach notification, the adoption of appropriate privacy governance, including policies, procedures, training and audits, and the use of third-party processors in connection with the processing of personal data. The GDPR also imposes strict rules on the transfer of personal data out of the EU, including to the U.S., provides an enforcement authority and imposes large penalties for noncompliance, including the potential for fines of up to €20 million or up to 4% of the total worldwide annual global revenues of the noncompliant entity, whichever is greater. The GDPR requirements apply not only to third-party transactions, but also to transfers of information between us and our subsidiaries, including employee information. In addition, in January 2021, following its exit from the EU, the UK transposed the GDPR into its domestic law with its own version of the GDPR (combining the GDPR and the UK Data Protection Act of 2018) (UK GDPR), which currently imposes the same obligations as the GDPR in most material respects and provides for fines of up £17.5 million or up to 4% of the total worldwide annual global revenues of the noncompliant entity, whichever is greater.

Complying with these numerous, complex and often changing regulations is expensive and difficult, and failure to comply with any privacy laws or data security laws or any security incident or breach involving the misappropriation, loss or other unauthorized processing, use or disclosure of sensitive or confidential patient, consumer or other personal information, whether by us, one of our CROs or business associates or another third party, could adversely affect our business, financial condition and results of operations, including but not limited to: investigation costs; material fines and penalties; compensatory, special, punitive and statutory damages; litigation; consent orders regarding our privacy and security practices; requirements that we provide notices, credit monitoring services and/or credit restoration services or other relevant services to impacted individuals; adverse actions against our licenses to do business; reputational damage; and injunctive relief. The recent implementation of the CCPA, GDPR and UK GDPR has increased our responsibility and liability in relation to personal data that we process, including in clinical trials, and we may in the future be required to put in place additional mechanisms to ensure compliance with the CCPA, GDPR, UK GDPR and other applicable laws and regulations, which could divert management’s attention and increase our cost of doing business. In addition, new regulation or legislative actions regarding data privacy and security (together with applicable industry standards) may increase our costs of doing business. In this regard, we expect that there will continue to be new proposed laws, regulations and industry standards relating to privacy and data protection in the U.S., the United Kingdom, the EU and other jurisdictions, and we cannot determine the impact such future laws, regulations and standards may have on our business.

We cannot assure you that our CROs or other third-party service providers with access to our or our customers’, suppliers’, trial patients’ and employees’ personally identifiable and other sensitive or confidential information in relation to which we are responsible will not breach contractual obligations imposed by us, or that they will not experience data security breaches, which could have a corresponding effect on our business, including putting us in breach of our obligations under privacy laws and regulations and/or which could in turn adversely affect our business, results of operations and financial condition. We cannot assure you that our contractual measures and our own privacy and security-related safeguards will protect us from the risks associated with the third-party processing, use, storage and transmission of such information. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

We and our third-party contractors must comply with environmental, health and safety laws and regulations. A failure to comply with these laws and regulations could expose us to significant costs or liabilities.

We and any of our third-party contract manufacturers or suppliers are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, generation, manufacture, storage, treatment and disposal of hazardous materials and wastes. Hazardous chemicals, including flammable and biological materials, are involved in certain aspects of our business, and we cannot eliminate the risk of injury or contamination from the use, generation, manufacture, distribution, storage, handling, treatment or disposal of hazardous materials and wastes. In the event of contamination or injury, or failure to comply with such environmental, health and safety laws and regulations, we could be held liable for any resulting damages, fines and penalties associated with such liability, which could exceed our assets and resources.

Although we will maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of biological or hazardous materials, or wastes arising out of and in the course of employment, this insurance may not provide adequate coverage against potential liabilities. We do not maintain comprehensive insurance coverage for liabilities arising from medical or hazardous materials, environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials.

Environmental, health and safety laws and regulations are becoming increasingly more stringent. 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 research, development, or production efforts, which could harm our business, prospects, financial condition or results of operations. Our failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

Coverage and reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our product candidates profitably.

In both domestic and foreign markets, sales of our product candidates, if approved, depend on the availability of coverage and adequate reimbursement from third-party payors. Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. Regulatory authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications, which could affect our ability or that of our collaborators to sell our product candidates profitably. In addition, third-party payors are requiring higher levels of evidence of the benefits and clinical outcomes of new technologies and are challenging the prices charged. Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Patients are unlikely to use our product candidates unless coverage is provided, and reimbursement is adequate to cover a significant portion of the cost of our product candidates. Such third-party payors include government health programs such as Medicare and Medicaid, managed care providers, private health insurers and other organizations. Obtaining coverage and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance. In addition, because our product candidates represent new approaches to the treatment of cancer, we cannot accurately estimate the potential revenues from our product candidates.

Government authorities and third-party payors decide which drugs and treatments they will cover and the amount of reimbursement. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. These payors may not view our products, if any, as cost-effective, and coverage and reimbursement may not be available to our customers, or those of our collaborators, or may not be sufficient to allow our products, if any, to be marketed on a competitive basis. If reimbursement is not available, or is available only to limited levels, our product candidates may be competitively disadvantaged, and we, or our collaborators, may not be able to successfully commercialize our product candidates. Alternatively, securing favorable reimbursement terms may require us to compromise pricing and prevent us from realizing an adequate margin over cost. Reimbursement by a third-party payor may depend upon a number of factors, including, but not limited to, 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.

In the U.S., no uniform policy of coverage and reimbursement for products exists among third-party payors. Therefore, coverage and reimbursement for 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 product candidates to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained. Moreover, the factors noted above have continued to be the focus of policy and regulatory debate that has, thus far, shown the potential for movement towards permanent policy changes; this trend is likely to continue, and may result in more or less favorable impacts on pricing. The recent and ongoing series of congressional hearings relating to drug pricing has presented heightened attention to the biopharmaceutical industry, creating the potential for political and public pressure, while the potential for resulting legislative or policy changes presents uncertainty. Congress is considering legislation that, if passed, could have significant impact on prices of prescription drugs covered by Medicare, including limitations on drug price increases. The impact of these regulations and any future healthcare measures and agency rules implemented by the Biden administration on us and the pharmaceutical industry as a whole is currently unknown. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates if approved. Complying with any new legislation and regulatory changes could be time-intensive and expensive, resulting in a material adverse effect on our business.

Prices paid for a drug also vary depending on the class of trade. Prices charged to government customers are subject to price controls, including ceilings, and private institutions obtain discounts through group purchasing organizations. Net prices for drugs may be further reduced by mandatory discounts or rebates required by government healthcare programs and demanded by private payors. It is also not uncommon for market conditions to warrant multiple discounts to different customers on the same unit, such as purchase discounts to institutional care providers and rebates to the health plans that pay them, which reduces the net realization on the original sale.

In addition, federal programs impose penalties on manufacturers of drugs marketed under a BLA or NDA, in the form of mandatory additional rebates and/or discounts if commercial prices increase at a rate greater than the Consumer Price Index-Urban, and these rebates and/or discounts, which can be substantial, may impact our ability to raise commercial prices. For example, under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates than it receives on the sale of products, which could have a material impact on our business. Cost control initiatives could cause us, or our collaborators, to decrease, discount, or rebate a portion of the price we, or they, might establish for products, which could result in lower than anticipated product revenues. If the realized prices for our product candidates, if any, decrease or if governmental and other third-party payors do not provide adequate coverage or reimbursement, our prospects for revenues and profitability will suffer.

Even if we obtain coverage for a given product, the resulting approved reimbursement payment rates might not be high enough to allow us to establish or maintain a market share sufficient to realize a sufficient return on our or their investments or achieve or sustain profitability or may require co-payments that patients find unacceptably high. If payors subject our product candidates to maximum payment amounts or impose limitations that make it difficult to obtain reimbursement, providers may choose to use therapies which are less expensive when compared to our product candidates. Additionally, if payors require high copayments, beneficiaries may decline prescriptions and seek alternative therapies. We may need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of any future products to the satisfaction of hospitals and other target customers and their third-party payors. Such studies might require us to commit a significant amount of management time and financial and other resources. Our future products might not ultimately be considered cost-effective. Adequate third-party coverage and reimbursement might not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product development.

We, and our collaborators, cannot be sure that coverage will be available for any product candidate that we, or they, commercialize and, if available, that the reimbursement rates will be adequate. Further, the net reimbursement for drug products may be subject to additional reductions if there are changes to laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the U.S. An inability to promptly obtain coverage and adequate payment rates from both government-funded and private payors for any of our product candidates for which we obtain marketing approval could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products, and our overall financial condition.

There have been, and likely will continue to be, legislative and regulatory proposals at the federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. We cannot predict the initiatives that may be adopted in the future. The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare and/or impose price controls may adversely affect:

•the demand for our product candidates, if we obtain regulatory approval;

•our ability to set a price that we believe is fair for our product candidates;

•our ability to generate revenues and achieve or maintain profitability;

•the level of taxes that we are required to pay; and

•the availability of capital.

Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors, which may adversely affect our future profitability. A particular challenge for our product candidates arises from the fact that they will primarily be used in an inpatient setting. Inpatient reimbursement generally relies on stringent packaging rules that may mean that there is no separate payment for our product candidates. Additionally, data used to set the payment rates for inpatient admissions is usually several years old and would not take into account all of the additional therapy costs associated with the administration of our product candidates. If special rules are not created for reimbursement for immunotherapy treatments such as our product candidates, hospitals might not receive enough reimbursement to cover their costs of treatment, which will have a negative effect on their adoption of our product candidates.

We may face difficulties from changes to current regulations and future legislation.

In the U.S. and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities, and affect our ability, or the ability of our collaborators, to profitably sell any products for which we obtain marketing approval. We expect that current laws, as well as other federal and state healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria, increased regulatory burdens and operating costs, decreased revenues from our biopharmaceutical product candidates, decreased potential returns from our development efforts, and additional downward pressure on the price that we, or our collaborators, may receive for any approved products.

Since enactment of the ACA in 2010, in both the U.S. and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could impact our ability to sell our product candidates profitably. These changes included aggregate reductions of Medicare payments to providers of up to 2% per fiscal year, effective April 1, 2013, which, due to subsequent legislative amendments, will stay in effect through 2030, with the exception of a temporary suspension implemented under various COVID‑19 relief legislation from May 1, 2020 through March 31, 2022, followed by a 1% payment adjustment from April 1 to June 30, 2022 and a 2% payment adjustment beginning July 1, 2022, unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012 (ATRA) was approved which, 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. These laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our product candidates, if approved, and accordingly, our financial operations.

Since its enactment, various portions of the ACA have been subject to judicial and constitutional challenges. In June 2021, the United States Supreme Court held that Texas and other challengers had no legal standing to challenge the ACA, dismissing the case without specifically ruling on the constitutionality of the ACA. Accordingly, the ACA remains in effect in its current form. It is unclear how this Supreme Court decision, future litigation, or healthcare measures promulgated by the Biden administration will impact our business, financial condition and results of operations. Complying with any new legislation or reversing changes implemented under the ACA could be time-intensive and expensive, resulting in a material adverse effect on our business.

Any reduction in reimbursement from Medicare or other government healthcare programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenues, attain profitability or commercialize our product candidates.

Legislative and regulatory proposals may also be made to expand post-approval requirements and restrict sales and promotional activities for drugs. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance, or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

Table of Contents

In addition, there have been increasing legislative efforts and enforcement interest in the U.S. with respect to drug pricing practices, including 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 2020, the Trump administration used several means to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives, some of which resulted in lawsuits against the U.S Department of Health and Human Services challenging various aspects of the rules. The impact of these lawsuits as well as legislative, executive, and administrative actions of the Biden administration on us and the pharmaceutical industry as a whole remains unclear. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological 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.

We are unable to predict the future course of federal or state healthcare legislation in the U.S. directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The ACA and any further changes in the law or regulatory framework that reduce our revenues or increase our costs could also have a material and adverse effect on our business, financial condition and results of operations. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our current product candidates and any future product candidates or additional pricing pressures. It is possible that additional governmental action is taken to address the COVID-19 pandemic.

Governments outside the U.S. tend to impose strict price controls, which may adversely affect our revenues, if any.

In international markets, reimbursement and health care payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. In some countries, particularly the countries of the EU, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain coverage and reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. There can be no assurance that our product candidates will be considered cost-effective by third-party payors, that an adequate level of reimbursement will be available, or that the third-party payors’ reimbursement policies will not adversely affect our ability to sell our product candidates profitably. If reimbursement of our product candidates is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed, possibly materially.

Our employees, independent contractors, consultants, commercial partners, principal investigators, CROs, suppliers and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk of employee fraud or other illegal activity by our employees, independent contractors, consultants, commercial partners, principal investigators, CROs, suppliers and vendors. Misconduct by these parties could include intentional, reckless and/or negligent conduct that fails to: comply with the laws of the FDA and other similar foreign regulatory bodies, provide true, complete and accurate information to the FDA and other similar foreign regulatory bodies, comply with manufacturing standards we have established, comply with healthcare fraud and abuse laws in the U.S. and similar foreign fraudulent misconduct laws, or report financial information or data accurately or to disclose unauthorized activities to us. If we obtain FDA approval of any of our product candidates and begin commercializing those product candidates in the U.S., our potential exposure under such laws will increase significantly, and our costs associated with compliance with such laws are also likely to increase. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry, are subject to extensive laws and regulations designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials, which could result in regulatory sanctions and serious harm to our reputation.

Table of Contents

It is not always possible to identify and deter misconduct or other improper activities by our employees or third parties that we engage for our business operations and the precautions we take to detect and prevent inappropriate conduct 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 such laws or regulations. 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 material adverse effect on our business, financial condition, results of operations and prospects, including the imposition of significant fines or other sanctions, including exclusion from government healthcare programs, and serious harm to our reputation. In addition, the approval and commercialization of any of our product candidates outside the U.S. will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws. Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve substantial costs.

Risks Related to Intellectual Property

If we are unable to obtain, maintain, protect and enforce patent protection and other proprietary rights for our product candidates and technologies, we may not be able to compete effectively or operate profitably and our ability to prevent our competitors from commercializing similar or identical technology and product candidates would be adversely affected.

Our success is dependent in large part on our obtaining, maintaining, protecting and enforcing patents and other proprietary rights in the U.S. and other countries with respect to our product candidates and technology and on our ability to avoid infringing the intellectual property and other proprietary rights of others. Certain of our intellectual property rights are licensed from other entities, and as such the preparation and prosecution of any such patents and patent applications was not performed by us or under our control. Furthermore, patent law relating to the scope of claims in the biotechnology field in which we operate is still evolving and, consequently, patent positions in our industry may not be as strong as in other more well-established fields. The patent positions of biotechnology and pharmaceutical companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved and has been the subject of much litigation in recent years. No consistent policy regarding the breadth of claims allowed in biotechnology patents has emerged to date. As a result, the issuance, scope, validity, enforceability, or commercial value of our patent rights remain highly uncertain.

Any future patents we obtain may not be sufficiently broad to prevent others from using our technology or from developing competing therapeutics and technology. There is no guarantee that any of our pending patent applications will result in issued or granted patents, any of our issued or granted patents will not later be found to be invalid or unenforceable, or any issued or granted patents will include claims sufficiently broad to cover our product candidates and technology, or to provide meaningful protection from our competitors. Our owned or in-licensed pending and future patent applications may not result in patents being issued that protect our Anktiva, saRNA, hAd5 and yeast technologies, cell-based therapies, aldoxorubicin or other product candidates and technologies or that effectively prevent others from commercializing competitive technologies and product candidates.

Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if patent applications we license or own currently or in the future issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. Any patents that we own or in-license may be challenged, narrowed, circumvented, or invalidated by third parties. Consequently, we do not know whether our Anktiva, saRNA, hAd5 and yeast technologies, cell-based therapies or other product candidates and technologies will be protectable or remain protected by valid and enforceable patents. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner which could materially adversely affect our business, financial condition, results of operations and growth prospects.

Table of Contents

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability and it is uncertain how much protection, if any, will be provided by our patents, including if they are challenged in the courts or patent offices or in other proceedings, such as re-examinations or oppositions, which may be brought in the U.S. or foreign jurisdictions to challenge the validity of a patent. A third party may challenge the validity or enforceability of a patent after its issuance. It is possible that a competitor may successfully challenge our patents or that a challenge will result in limiting their coverage. Moreover, it is possible that competitors may infringe our patents or successfully avoid the patented technology through design innovation. To counter infringement or other unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming, even if we were successful in stopping the violation of our patent rights.

We or our licensors may be subject to a third-party preissuance submission of prior art to the USPTO, or become involved in opposition, derivation, revocation, reexamination, post-grant and inter partes review, or interference proceedings or other similar proceedings challenging our owned or licensed patent rights. Should third parties file patent applications, or be issued patents claiming technology also used or claimed by our licensor(s) or by us in any future patent application, we, or one of our licensors, may be required to participate in interference proceedings in the USPTO to determine priority of invention for those patents or patent applications that are subject to the first-to-invent law in the U.S., or may be required to participate in derivation proceedings in the USPTO for those patents or patent applications that are subject to the first-inventor-to-file law in the U.S. We may be required to participate in such interference or derivation proceedings involving our issued patents and pending applications. We may also be required to participate in post-grant challenge proceedings, such as oppositions in a foreign patent office, that challenge our or our licensor’s priority of invention or other features of patentability with respect to our owned or in-licensed patents and patent applications. Such challenges may result in loss of patent rights, loss of exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our Anktiva, saRNA, hAd5 and yeast technologies, cell-based therapies or other product candidates and technologies. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate or render unenforceable, our owned or in-licensed patent rights, allow third parties to commercialize our Anktiva, saRNA, hAd5 and yeast technologies, cell-based therapies or other product candidates or technologies and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights.

If we or our collaborators are unsuccessful in any such proceeding or other priority or inventorship dispute, we may be required to cease using the technology or to obtain and maintain license rights from prevailing third parties, including parties involved in any such interference proceedings or other priority or inventorship disputes. A prevailing party in that case may not offer us a license on commercially acceptable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. If we are unable to obtain and maintain such licenses, we may need to cease the development, manufacture, and commercialization of one or more of the product candidates we may develop. The loss of exclusivity or the narrowing of our owned and licensed patent claims could limit our ability to stop others from using or commercializing similar or identical technology and products. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, given the amount of time required for the development, testing, and regulatory review of new product candidates, patents protecting such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our intellectual property may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Some of our owned and in-licensed patents and patent applications are, and may in the future be, co-owned with third parties. In addition, certain of our licensors co-own the patents and patent applications we in-license with other third parties with whom we do not have a direct relationship. Our exclusive rights to certain of these patents and patent applications are dependent, in part, on inter-institutional or other operating agreements between the joint owners of such patents and patent applications, who are not parties to our license agreements. If our licensors do not have exclusive control of the grant of licenses under any such third-party co-owners’ interest in such patents or patent applications or we are otherwise unable to secure such exclusive rights, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. In addition, we may need the cooperation of any such co-owners of our patents in order to enforce such patents against third parties, and such cooperation may not be provided to us. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations and growth prospects.

If any of our owned or in-licensed patent applications do not issue as patents in any jurisdiction, we may not be able to compete effectively.

Changes in either the patent laws or their interpretation in the U.S. and other countries may diminish our ability to protect our inventions, obtain, maintain, and enforce our intellectual property rights and, more generally, could affect the value of our intellectual property or narrow the scope of our owned and licensed patents. With respect to both in-licensed and owned intellectual property, we cannot predict whether the patent applications we and our licensors are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient protection from competitors or other third parties. The patent prosecution process is expensive, time-consuming, and complex, and we may not be able to file, prosecute, maintain, enforce, or license all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output in time to obtain patent protection. Although we enter into nondisclosure and confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development output, such as our employees, corporate collaborators, outside scientific collaborators, CROs, CMOs, consultants, advisors, and other third parties, any of these parties may breach the agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. In addition, our ability to obtain and maintain valid and enforceable patents depends on whether the differences between our inventions and the prior art allow our inventions to be patentable over the prior art. Furthermore, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the U.S. and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we or our licensors were the first to make the inventions claimed in any of our owned or licensed patents or pending patent applications, or that we or our licensors were the first to file for patent protection of such inventions.

We or our licensors, collaborators, or any future strategic partners may become subject to third-party claims or litigation alleging infringement of patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or enforce our patents or other intellectual property or the patents or other intellectual property of our licensors, all of which could be expensive, time-consuming and unsuccessful, may delay or prevent the development and commercialization of our product candidates, or may put our patents and other proprietary rights at risk.

If we or one of our licensors initiate legal proceedings against a third party to enforce a patent covering one of our product candidates or other technologies, the defendant could counterclaim that the patent is invalid and/or unenforceable or that we infringe their patents. In patent litigation in the U.S., defendant counterclaims alleging invalidity and/or unenforceability are commonplace, and there are numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or other applicable body, or made a misleading statement, during prosecution. Third parties may also raise similar claims before administrative bodies in the U.S. or abroad, even outside the context of litigation. Such mechanisms include re-examination, post grant review, inter partes review, interference proceedings, derivation proceedings, and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings).

Table of Contents

With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we, our licensor, our or our licensor’s patent counsel and the patent examiner were unaware during prosecution. Moreover, even if our patents were to survive such a litigation challenge to their validity, the patents might still be held to be valid but unenforceable if a court were to decide that the patents are being enforced in a manner inconsistent with the antitrust laws, or that the patents were obtained through deceit during patent office examination or other such failure of sufficient candor to the patent office. If a third party were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our product candidates. Such a loss of patent protection could have a material adverse impact on our business, financial condition, results of operations and prospects.

The cost to us of any litigation or other proceeding relating to intellectual property rights, even if resolved in our favor, could be substantial. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources, including our scientists and management, from our business.

An adverse result in any litigation or defense proceeding could put one or more of our owned or licensed patents at risk of being invalidated, held unenforceable, or interpreted narrowly, and could put our patent applications at risk of not issuing. Such proceedings could result in revocation or cancellation of, or amendment to, our patents in such a way that they no longer cover our product candidates or technologies. If the outcome of litigation is adverse to us, third parties may be able to use our patented invention without payment to us. In addition, in an infringement proceeding, there is a risk that a court may decide that one or more of our patents is not valid or is unenforceable and that we do not have the right to stop the other party from using the inventions. There is also the risk that, even if the validity of our patents were upheld, a court would refuse to stop the other party on the grounds that its activities are not covered by, that is, do not infringe, our patents. 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 this type of litigation.

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, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing, or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be better able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. The outcome following legal assertions of invalidity and unenforceability is unpredictable. 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.

The use of our technology and product candidates could potentially conflict with the rights of others, and third-party claims of intellectual property infringement, misappropriation or other violation against us, our licensors or our collaborators may prevent or delay the development and commercialization of our product candidates and technologies.

Our commercial success depends in part on our, our licensors’ and our collaborators’ ability to avoid infringing, misappropriating and otherwise violating the patents and other intellectual property rights of third parties. There is a substantial amount of complex litigation involving patents and other intellectual property rights in the biopharmaceutical industry. Our potential competitors or other parties may have, develop or acquire patent or other intellectual property rights that they could assert against us. If they do so, then we may be required to alter our product candidates, pay licensing fees or cease our development and commercialization activities with respect to the applicable product candidates or technologies. If our product candidates conflict with patent or other intellectual property rights of others, such parties could bring legal actions against us or our collaborators, licensees, suppliers or customers, claiming damages and seeking to enjoin manufacturing, use and marketing of the affected products.

Table of Contents

Although we have conducted freedom-to-operate (FTO) analyses of the patent landscape with respect to our lead product candidates and continue to undertake FTO analyses of our manufacturing processes, our Anktiva product candidate, and contemplated future processes and products, because patent applications do not publish for 18 months, and because the claims of patent applications can change over time, no FTO analysis can be considered exhaustive. We may not be aware of patents that have already been issued and that a competitor or other third party might assert are infringed by our current or future product candidates or technologies. It is also possible that we could be found to have infringed patents owned by third parties of which we are aware, but which we do not believe are relevant to our product candidates or technologies. In addition, because patent applications can take many years to issue, there may be currently pending patent applications that may later result in issued patents that our product candidates or technologies may infringe. Furthermore, patent and other intellectual property rights in biotechnology remains an evolving area with many risks and uncertainties. As such, we may not be able to ensure that we can market our product candidates without conflict with the rights of others.

If intellectual property-related legal actions asserted against us are successful, in addition to any potential liability for damages (including treble damages and attorneys’ fees for willful infringement), we could be enjoined from, or required to obtain a license to continue, manufacturing, promoting the use of or marketing the affected products. We may not prevail in any legal action and a required license under the applicable patent or other intellectual property may not be available on acceptable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. We also could be required to redesign our infringing products, which may be impossible or require substantial time and monetary expenditure.

Defense of infringement claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of management and other employee resources from our business, and may impact our reputation. Some of our competitors may be able to sustain the costs of litigation or administrative proceedings more effectively than we can because of greater financial resources. 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, it could have a substantial adverse effect on the price of our common stock. The occurrence of any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

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

Periodic maintenance fees, renewal fees, annuity fees, and various other government fees on patents and patent applications are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of a patent. The USPTO and various foreign governmental patent agencies require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process. In certain circumstances, we rely on our licensors to pay these fees and take the necessary actions to comply with these requirements. 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. Noncompliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, our competitors might be able to enter the market with similar or identical products or technology, which would have a material adverse impact on our business, financial condition, results of operations and prospects.

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

As is the case with other immunotherapy and biopharmaceutical companies, our success is dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involve both technological and legal complexity, and is therefore costly, time-consuming and inherently uncertain. In addition, the U.S. has recently enacted and is currently implementing wide-ranging patent reform legislation. Assuming that other requirements for patentability are met, prior to March 2013, in the U.S., the first to invent the claimed invention was entitled to the patent, while outside the U.S., the first to file a patent application was entitled to the patent. After March 2013, under the Leahy-Smith America Invents Act (the America Invents Act) enacted in September 2011, the U.S. transitioned to a first-to-file system in which, assuming that other requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. A third party that files a patent application in the USPTO after March 2013, 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 such third party. This will require us to be cognizant of the time from invention to filing of a patent application. Since patent applications in the U.S. and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensors were the first to either file any patent application related to our product candidates or other technologies or invent any of the inventions claimed in our or our licensor’s patents or patent applications. The America Invents Act also includes a number of significant changes that affect the way patent applications will be prosecuted and also may affect patent litigation. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO-administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. Therefore, the America Invents Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our owned or in-licensed patent applications and the enforcement or defense of our owned or in-licensed issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Additionally, U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened 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 Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. While we do not believe that any of the patents owned or licensed by us will be found invalid based on the foregoing, we cannot predict how future decisions by Congress, the federal courts or the USPTO may impact the value of our patents.

Our rights to develop and commercialize our product candidates and technologies are subject, in part, to the terms and conditions of licenses granted to us by others.

We will rely on licenses to certain patent rights and proprietary technology from third parties that are important or necessary to the development of aldoxorubicin as well as products enabled by our adenoviral and yeast, including Tarmogen, vaccine technologies.

License agreements may not provide exclusive rights to use certain licensed intellectual property and technology in all relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and product candidates in the future. As a result, we may not be able to prevent competitors or other third parties from developing and commercializing competitive products that also utilizes technology that we have in-licensed.

Table of Contents

In addition, subject to the terms of any such license agreements, we do not have the right to control the preparation, filing, prosecution and maintenance, and we may not have the right to control the enforcement, and defense of patents and patent applications covering the technology that we license from third parties. We cannot be certain that our in-licensed or out-licensed patents and patent applications that are controlled by our licensors or licensees will be prepared, filed, prosecuted, maintained, enforced, and defended in a manner consistent with the best interests of our business. If our licensors or licensees fail to prosecute, maintain, enforce, and defend such patents, or lose rights to those patents or patent applications, the rights we have licensed may be reduced or eliminated, our right to develop and commercialize Anktiva and any of our product candidates that are subject of such licensed rights could be adversely affected, and we may not be able to prevent competitors from making, using and selling competing products. In addition, even where we have the right to control patent prosecution of patents and patent applications we have licensed to and from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensees, our licensors and their counsel that took place prior to the date upon which we assumed control over patent prosecution.

Furthermore, our owned and in-licensed patents may be subject to a reservation of rights by one or more third parties. For example, certain of our in-licensed intellectual property was funded in part by the U.S. government. As a result, the U.S. government may have certain rights to such intellectual property. When new technologies are developed with U.S. government funding, the U.S. government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the U.S. government to use the invention or to have others use the invention on its behalf. The U.S. government’s rights may also permit it to disclose the funded inventions and technology to third parties and to exercise march-in rights to use or allow third parties to use the technology we have licensed that was developed using U.S. government funding. The U.S. government may exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, or because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the U.S. in certain circumstances if this requirement is not waived. Any exercise by the U.S. government of such rights or by any third party of its reserved rights could have a material adverse effect on our competitive position, business, financial condition, results of operations and growth prospects.

If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we may be required to pay damages and we could lose license rights that are important to our business.

We have entered into license agreements with third parties and may need to obtain additional licenses from others to advance our research or allow commercialization of our product candidates. We may be unable to obtain certain additional licenses at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend significant time and resources to redesign our technology, product candidates, or the methods for manufacturing them or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates or continue to utilize our existing technology, which could harm our business, financial condition, results of operations and growth prospects significantly. We cannot provide any assurances that third-party patents do not exist which might be enforced against our current technology, manufacturing methods, product candidates, or future methods or products resulting in either an injunction prohibiting our manufacture or future sales, or, with respect to our future sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties, which could be significant.

Table of Contents

In addition, each of our license agreements, and we expect our future agreements, will impose various development, diligence, commercialization, and other obligations on us. Certain of our license agreements also require us to meet development timelines, or to exercise commercially reasonable efforts to develop and commercialize licensed products, in order to maintain the licenses. In spite of our efforts, our licensors might conclude that we have materially breached our obligations under such license agreements and might therefore terminate the license agreements, thereby removing or limiting our ability to develop and commercialize products and technology covered by these license agreements. If these in-licenses are terminated, or if the underlying patents fail to provide the intended exclusivity, competitors or other third parties would have the freedom to seek regulatory approval of, and to market, products identical to ours and we may be required to cease our development and commercialization of certain of our product candidates or of Anktiva. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations and growth prospects.

Moreover, disputes may arise regarding intellectual property subject to a licensing agreement, including:

•the scope of rights granted under the license agreement and other interpretation-related issues;

•the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;

•the sublicensing of patent and other rights under our collaborative development relationships;

•our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

•the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and

•the priority of invention of patented technology.

In addition, the agreements under which we currently license intellectual property or technology from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations and growth prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations and growth prospects.

We have limited foreign intellectual property rights and may not be able to protect our intellectual property rights in various jurisdictions throughout the world.

We have limited intellectual property rights outside the U.S. Filing, prosecuting and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the U.S. can be less extensive than those in the U.S. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S., or from selling or importing products made using our inventions in and into the U.S. or other jurisdictions. Competitors may use our 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 have patent protection, but enforcement is not as strong as that in the U.S. These products may compete with our product candidates and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Table of Contents

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biopharmaceutical products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many 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, financial condition, results of operations and prospects may be adversely affected.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed trade secrets or other confidential information of third parties or claims asserting ownership of what we regard as our own intellectual property.

We have received confidential and proprietary information from third parties and their employees and contractors. In addition, we plan to employ and contract with individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed the trade secrets or other confidential information of these third parties or our employees’ former employers. Litigation may be necessary to defend against or pursue these claims. Even if we are successful in resolving these claims, litigation could result in substantial cost and be a distraction to our management and employees.

In addition, while it is our policy to require our employees, consultants and independent contractors who may be involved in the conception or 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, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Table of Contents

We may not be able to license or acquire new or necessary intellectual property rights or technology from third parties.

An element of our intellectual property strategy is to license intellectual property rights and technologies from third parties and/or our affiliates. Other parties, including our competitors or our affiliates, may have patents relevant to our business, may have already filed patent applications relevant to our business, and are likely filing patent applications potentially relevant to our business. In order to avoid infringing these patents, we may find it necessary or prudent to obtain licenses to such patents from such parties. In addition, with respect to any patents we co-own with other parties, including our affiliates, we may require licenses to such co-owners’ interest to such patents. The licensing or acquisition of intellectual property rights is a competitive area, and other more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital 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 or at all. No assurance can be given that we will be successful in licensing any additional rights or technologies from third parties and/or our affiliates. Our inability to license the rights and technologies that we have identified, or that we may in the future identify, could have a material adverse impact on our ability to complete the development of our product candidates or to develop additional product candidates. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. Failure to obtain any necessary rights or licenses may detrimentally affect our planned development of our current or future additional product candidates and could increase the cost, and extend the timelines associated with our development, of such other products, and we may have to abandon development of the relevant program or product candidate. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

If we do not obtain patent term extension and data exclusivity for any product candidates we may develop, our business may be materially harmed.

Depending upon the timing, duration and specifics of any FDA marketing approval of any product candidates we may develop, one or more of our owned or in-licensed U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 (the Hatch-Waxman Act). The Hatch-Waxman Act permits a patent term extension of up to five years as compensation for patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval. Only one patent may be extended per new drug, and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. Similar extensions as compensation for patent term lost during regulatory review processes are also available in certain foreign countries and territories, such as in Europe under a Supplementary Patent Certificate. However, we may not be granted an extension in the U.S. and/or foreign countries and territories because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is shorter than what we request, our competitors may obtain approval of competing products following our patent expiration, and our business, financial condition, results of operations and growth prospects could be materially harmed.

We may be subject to claims challenging rights in our patents and other intellectual property.

We or our licensors may be subject to claims that former employees, collaborators or other third parties have an interest in our owned or in-licensed patents, trade secrets, or other intellectual property, including as an inventor or co-inventor. For example, we or our licensors may have disputes arise from conflicting obligations of employees, consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship, or our or our licensors’ ownership of our owned or in-licensed patents, trade secrets or other intellectual property. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of or right to use valuable intellectual property. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patents for Anktiva, saRNA, hAd5 and yeast technologies, cell therapies, and other product candidates and technologies, we also rely on trade secrets and confidentiality agreements to protect our unpatented know-how, technology, and other proprietary information and to maintain our competitive position. Trade secrets and know-how can be difficult to protect. We expect our trade secrets and know-how will over time be disseminated within the industry through independent development, the publication of journal articles describing the methodology, and the movement of personnel from academic to industry scientific positions.

We seek to protect these trade secrets and other proprietary technology, in part, by entering into nondisclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, CROs, CMOs, consultants, advisors, and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants as well as train our employees not to bring or use proprietary information or technology from former employers to us or in their work, and remind former employees when they leave their employment of their confidentiality obligations. We cannot guarantee that we have entered into such agreements with each party that may have or have had access to our trade secrets or proprietary technology and processes. Despite our efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive, and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the U.S. are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor or other third party, our competitive position would be materially and adversely harmed.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential partners or customers in our markets of interest. At times, competitors or other third parties may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely affect our business, financial condition, results of operations and growth prospects.

Intellectual property rights do not necessarily address all potential threats.

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. For example:

•others may be able to make products that are similar to our product candidates or utilize similar technology but that are not covered by the claims of the patents that we license or may own;

•we, or our current or future licensors or collaborators, might not have been the first to make the inventions covered by the issued patent or pending patent application that we license or own now or in the future;

•we, or our current or future licensors or collaborators, might not have been the first to file patent applications covering certain of our or their inventions;

100

Table of Contents

•others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our owned or licensed intellectual property rights;

•it is possible that our current or future pending owned or licensed patent applications will not lead to issued patents;

•issued patents that we hold rights to may be held invalid or unenforceable, including as a result of legal challenges by our competitors or other third parties;

•our competitors or other third parties might conduct research and 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;

•we may not develop additional proprietary technologies that are patentable;

•the patents of others may harm our business; and

•we may choose not to file a patent in order to maintain certain trade secrets or know-how, and a third party may subsequently file a patent covering such intellectual property.

Should any of these events occur, they could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Risks Related to Our Common Stock

Dr. Soon-Shiong, our Executive Chairman, Global Chief Scientific and Medical Officer and our principal stockholder, has significant interests in other companies which may conflict with our interests.

Our Executive Chairman, Global Chief Scientific and Medical Officer and our principal stockholder, Dr. Soon-Shiong, is the founder of NantWorks. The various NantWorks companies are currently exploring opportunities in the immunotherapy, oncology, infectious disease and inflammatory disease fields. In particular, we have agreements with a number of related parties that provide services, technology and equipment for use in their efforts to develop their product pipelines. Dr. Soon-Shiong holds a controlling interest, either directly or indirectly, in these entities. Consequently, Dr. Soon-Shiong’s interests may not be aligned with our other stockholders and he may from time to time be incentivized to take certain actions that benefit his other interests and that our other stockholders do not view as being in their interest as investors in our company. In addition, other companies affiliated with Dr. Soon-Shiong may compete with us for business opportunities or, in the future, develop products that are competitive with ours (including products in other therapeutic fields which we may target in the future). Moreover, even if they do not directly relate to us, actions taken by Dr. Soon-Shiong and the companies with which he is involved could impact us.

We are also pursuing supply arrangements for various investigational agents controlled by affiliates to be used in their clinical trials. If Dr. Soon-Shiong were to cease his affiliation with us or NantWorks, these entities may be unwilling to continue these relationships with us on commercially reasonable terms, or at all, and as a result may impede our ability to control the supply chain for our combination therapies. These collaboration agreements do not typically specify how sales will be apportioned between the parties upon successful commercialization of the product. As a result, we cannot guarantee that we will receive a percentage of the revenues that is at least proportional to the costs that we will incur in commercializing the product candidate.

We have entered into shared services agreements with NantWorks, pursuant to which NantWorks and its affiliates provide corporate, general and administrative and other support services to us. If Dr. Soon-Shiong was to cease his affiliation with us or with NantWorks, we may be unable to establish or maintain this relationship with NantWorks on a commercially reasonable basis, if at all. As a result, we could experience a lack of business continuity due to loss of historical and institutional knowledge and a lack of familiarity of new employees and/or new service providers with business processes, operating requirements, policies and procedures, and we may incur additional costs as new employees and/or service providers gain necessary experience. In addition, the loss of the services of NantWorks might significantly delay or prevent the development of our product candidates or achievement of other business objectives by diverting management’s attention to transition matters and identification of suitable replacements, if any, and could have a material adverse effect on our business and results of operations.

Dr. Soon-Shiong, through his voting control of the company, has the ability to control actions that require stockholder approval.

Dr. Soon-Shiong, through his direct and indirect ownership of the company’s common stock, has voting control of the company. As of December 31, 2021, Dr. Soon-Shiong and his affiliates beneficially own approximately 78.7% of the company’s common stock outstanding.

Additionally, an affiliate of Dr. Soon-Shiong holds a warrant to purchase 1,638,000 shares of the company’s common stock that will become exercisable if certain performance conditions are satisfied. Dr. Soon-Shiong and his related party also hold approximately $279.5 million in the aggregate of CVRs issued to the former stockholders of Altor in connection with NantCell’s acquisition of Altor. If the underlying conditions for payment are met, the CVRs become payable in cash or shares of the company’s common stock or any combination as the holder elects. Dr. Soon-Shiong and his related party have irrevocably agreed to receive shares of the company’s common stock in satisfaction of their CVRs.

During the year ended December 31, 2021, we executed a $300.0 million promissory note with an entity affiliated with Dr. Soon-Shiong that is due and payable on December 17, 2022. In the event of a default on the loan (as defined in the promissory note), including if we do not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at price of $5.67 per share. In addition, entities affiliated with Dr. Soon-Shiong hold promissory notes representing $306.3 million in indebtedness, including interest thereon, of the company as of December 31, 2021. Also Dr. Soon-Shiong has 926,064 stock options outstanding as of December 31, 2021, of which 900,000 are exercisable.

Dr. Soon-Shiong is in a position to control the outcome of corporate actions that require, or may be accomplished by, stockholder approval, including amending the bylaws of the company, the election or removal of directors and transactions involving a change of control. Dr. Soon-Shiong’s controlling ownership could limit the ability of the remaining stockholders of the company to influence corporate matters, and the interests of Dr. Soon-Shiong may not coincide with the company’s interests or the interests of its remaining stockholders.

In addition, pursuant to the Nominating Agreement between us and Cambridge Equities, LP (Cambridge), an entity that Dr. Soon-Shiong controls, Cambridge has the ability to designate one director to be nominated for election to the Board of Directors for as long as Cambridge continues to hold at least 20% of the issued and outstanding shares of our common stock. Dr. Soon-Shiong was selected by Cambridge to hold this board seat. Dr. Soon-Shiong and his affiliates will therefore have significant influence over management and significant control over matters requiring stockholder approval, including the annual election of directors and significant corporate transactions, such as a merger or other sale of our company or its assets, for the foreseeable future. This control will limit stockholders’ ability to influence corporate matters and, as a result, we may take actions that our stockholders do not view as beneficial. As a result, the market price of our common stock could be adversely affected.

The market price of our common stock has been and may continue to be volatile, and investors may have difficulty selling their shares.

Although our common stock is listed on the Nasdaq Global Select Market, the market for our shares has demonstrated varying levels of trading activity. You may not be able to sell your shares quickly or at the market price if trading in shares of our common stock is not active. Further, an inactive market may also impair our ability to raise capital by selling shares of our common stock and may impair our ability to enter into strategic partnerships or acquire companies or products by using our shares of common stock as consideration.

Table of Contents

The stock market in general and the market for biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. The market price of our common stock has been and may continue to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control, including:

•the commencement, enrollment or results of the planned clinical trials of our product candidates or any future clinical trials we may conduct, or changes in the development status of our product candidates;

•any delay in our regulatory filings for our product candidates and any adverse development or perceived adverse development with respect to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a “refusal to file” letter or a request for additional information;

•adverse results or delays in clinical trials;

•our decision to initiate a clinical trial, not to initiate a clinical trial or to terminate an existing clinical trial;

•adverse regulatory decisions, including failure to receive regulatory approval of our product candidates;

•changes in laws or regulations applicable to our products, including but not limited to clinical trial requirements for approvals;

•our failure to commercialize our product candidates;

•additions or departures of key scientific or management personnel;

•unanticipated serious safety concerns related to the use of our product candidates;

•announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments;

•our ability to effectively manage our growth;

•variations in our quarterly operating results;

•our liquidity position and the amount and nature of any debt we may incur;

•announcements that our revenue or income are below or that costs or losses are greater than analysts’ expectations;

•publication of research reports about us or our industry, or immunotherapy in particular, or positive or negative recommendations or withdrawal of research coverage by securities analysts;

•changes in the market valuations of similar companies;

•sales of large blocks of our common stock;

•fluctuations in stock market prices and volumes;

•disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies;

•significant lawsuits, including patent or stockholder litigation;

•the perception of our clinical trial results by retail investors, which investors may be subject to the influence of information provided by third party investor websites and independent authors distributing information on the internet;

103

Table of Contents

•general economic slowdowns;

•coordinated actions by independent third-party actors to affect the price of certain stocks, coordinated via the Internet and otherwise; and

•other factors described in this “Risk Factors” section.

In the past, securities class action litigation has often been instituted against companies following periods of volatility in the market price of a company’s securities. This type of litigation could result in substantial costs and a diversion of management’s attention and resources, which would harm our business, operating results or financial condition.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plan, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our stockholders sell, or the market perceives that our stockholders intend to sell substantial amounts of our common stock in the public market, the market price of our common stock could decline significantly. In addition, our Executive Chairman and Global Chief Scientific and Medical Officer, Dr. Soon-Shiong, and his affiliates currently beneficially own approximately 78.7% of our outstanding shares of common stock as of December 31, 2021. Sales of stock by Dr. Soon-Shiong and his affiliates could have an adverse effect on the trading price of our common stock.

Certain holders of our common stock are entitled to certain rights with respect to the registration of their shares under the Securities Act of 1933, as amended (the Securities Act). Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares held by our affiliates as defined in Rule 144 under the Securities Act. Any sales of securities by these stockholders could have an adverse effect on the market price of our common stock.

In addition, we expect that additional capital may be needed in the future to continue our planned operations, including conducting clinical trials, commercialization efforts, expanded research and development activities and costs associated with operating as a public company. To raise capital, we may sell common stock, including as part of the ATM, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, including through the ATM, convertible securities or other equity securities, investors may be materially diluted and new investors could gain rights, preferences and privileges senior to the holders of our common stock.

We have incurred and will continue to incur costs as a result of operating as a public company and our management has been and will be required to devote substantial time to compliance initiatives and corporate governance practices, including maintaining an effective system of internal control over financial reporting.

As a public company listed in the U.S., we have incurred and will continue to incur significant additional legal, accounting and other expenses as a result of operating as a public company. In addition, changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002 (Sarbanes Oxley) and regulations implemented by the SEC and Nasdaq, may increase legal and financial compliance costs and make some activities more time consuming. These laws, regulations and standards are subject to varying interpretations and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. We intend to invest resources to create a larger finance function with additional personnel to comply with evolving laws, regulations and standards, and this investment will result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If, notwithstanding our efforts to comply with new laws, regulations and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us, and our business may be harmed.

104

Table of Contents

As a public company in the U.S., we are required, pursuant to Section 404 of Sarbanes-Oxley (Section 404) to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting. The controls and other procedures are designed to ensure that information required to be disclosed by us in the reports that we file with the SEC is disclosed accurately and is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

In the normal course of business our controls and procedures may become inadequate because of changes in conditions or the degree of compliance with these policies or procedures may deteriorate and material weaknesses in our internal control over financial reporting may be discovered. We may err in the design or operation of our controls, and all internal control systems, no matter how well designed and operated, can provide only reasonable assurance that the objectives of the control system are met. Because there are inherent limitations in all control systems, there can be no absolute assurance that all control issues have been or will be detected. If we are unable, or are perceived as unable, to produce reliable financial reports due to internal control deficiencies, investors could lose confidence in our reported financial information and operating results, which could result in a negative market reaction.

To fully comply with Section 404, we will need to retain additional employees to supplement our current finance staff, and we may not be able to do so in a timely manner, or at all. In addition, in the process of evaluating our internal control over financial reporting, we expect that certain of our internal control practices will need to be updated to comply with the requirements of Section 404 and the regulations promulgated thereunder, and we may not be able to do so on a timely basis, or at all. In the event that we are not able to demonstrate compliance with Section 404 in a timely manner, or are unable to produce timely or accurate financial statements, we may be subject to sanctions or investigations by regulatory authorities, such as the SEC or Nasdaq, and investors may lose confidence in our operating results and the price of our common stock could decline. Furthermore, if we are unable to certify that our internal control over financial reporting is effective and in compliance with Section 404, we may be subject to sanctions or investigations by regulatory authorities, such as the SEC or stock exchanges, and investors could lose confidence in the accuracy and completeness of our financial reports, which could hurt our business, the price of our common stock and our ability to access the capital markets.

Operating as a public company makes it more expensive for us to obtain directors’ and officers’ liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified persons to serve on the Board of Directors, on committees of the Board of Directors, or as members of senior management.

If a restatement of our consolidated financial statements were to occur, our stockholders’ confidence in the company’s financial reporting in the future may be affected, which could in turn have a material adverse effect on our business and stock price.

If any material weaknesses in our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may contain material misstatements, and we could be required to restate our financial results. In addition, if we are unable to successfully remediate any future material weaknesses in our internal controls or if we are unable to produce accurate and timely financial statements, our stock price may be adversely affected, and we may be unable to maintain compliance with applicable stock exchange listing requirements.

We have not paid cash dividends in the past and do not expect to pay dividends in the future. Any return on investment may be limited to the value of our common stock.

We have never paid cash dividends on our common stock and do not anticipate paying cash dividends for the foreseeable future. The payment of dividends on our common stock will depend on earnings, financial condition and other business and economic factors affecting us at such time as the Board of Directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on your investment will only occur if our stock price appreciates.

Because we are relying on the exemptions from corporate governance requirements as a result of being a “controlled company” within the meaning of the Nasdaq listing standards, you do not have the same protections afforded to stockholders of companies that are subject to such requirements.

Our Executive Chairman and Global Chief Scientific and Medical Officer, Dr. Soon-Shiong, and entities affiliated with him, control a majority of our common stock. As a result, we are a “controlled company” within the meaning of the Nasdaq listing standards. Under these rules, a company of which more than 50% of the voting power is held by an individual, a group or another company is a “controlled company” and may elect not to comply with certain Nasdaq corporate governance requirements, including (1) the requirement that a majority of the Board of Directors consist of independent directors, and (2) the requirement that we have a Nominating and Corporate Governance Committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities. Accordingly, you do not have the same protections afforded to stockholders of companies that are subject to all of the Nasdaq corporate governance requirements. However, our Board of Directors is currently comprised of a majority of independent directors and we currently have a Nominating and Corporate Governance Committee and the majority of the members of such committee are independent directors.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share price and trading volume could decline.

The trading market for our common stock will depend 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. There can be no assurance that analysts will cover us or provide favorable coverage. If one or more of the analysts who cover us downgrade our stock or change their opinion of our stock, our share price would likely decline. If one or more of these analysts’ cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

We are not subject to the provisions of Section 203 of the Delaware General Corporation Law (DGCL), which could negatively affect your investment.

We elected in our amended and restated certificate of incorporation to not be subject to the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns (or, in certain cases, within three years prior, did own) 15% or more of the corporation’s voting stock. Our decision not to be subject to Section 203 will allow, for example, our Executive Chairman and Global Chief Scientific and Medical Officer (who, with members of his immediate family and entities affiliated with him, currently beneficially own, in the aggregate, approximately 78.7% of our common stock as of December 31, 2021) to transfer shares in excess of 15% of our voting stock to a third-party free of the restrictions imposed by Section 203. This may make us more vulnerable to takeovers that are completed without the approval of our Board of Directors and/or without giving us the ability to prohibit or delay such takeovers as effectively.

106

Table of Contents

Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us or increase the cost of acquiring us, even if doing so would benefit our stockholders. These provisions include:

•a requirement that special meetings of stockholders be called only by the board of directors, president or chief executive officer;

•advance notice requirements for stockholder proposals and nominations for election to the board of directors; and

•the authority of the board of directors to issue preferred stock on terms determined by the board of directors without stockholder approval and which preferred stock may include rights superior to the rights of the holders of common stock.

These anti-takeover provisions and other provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws could make it more difficult for stockholders or potential acquirers to obtain control of our Board of Directors or initiate actions that are opposed by the then-current Board of Directors and could also delay or impede a merger, tender offer or proxy contest involving our company. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing or cause us to take other corporate actions you desire. Any delay or prevention of a change of control transaction or changes in our Board of Directors could cause the market price of our common stock to decline.

Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us.

Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that we will indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law. In addition, as permitted by Section 145 of the DGCL, our Amended and Restated Bylaws and our indemnification agreements that we have entered into with our directors and officers provide that:

•We will indemnify our directors and officers for serving us in those capacities or for serving other business enterprises at our request, to the fullest extent permitted by Delaware law. Delaware law provides that a corporation may indemnify such person if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the registrant and, with respect to any criminal proceeding, had no reasonable cause to believe such person’s conduct was unlawful.

•We may, in our discretion, indemnify employees and agents in those circumstances where indemnification is permitted by applicable law.

•We are required to advance expenses, as incurred, to our directors and officers in connection with defending a proceeding, except that such directors or officers shall undertake to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

•We are not obligated pursuant to our Amended and Restated Bylaws to indemnify a person with respect to proceedings initiated by that person against us or our other indemnitees except with respect to proceedings authorized by our Board of Directors or brought to enforce a right to indemnification.

•The rights conferred in our Amended and Restated Bylaws are not exclusive, and we are authorized to enter into indemnification agreements with our directors, officers, employees and agents and to obtain insurance to indemnify such persons.

•We may not retroactively amend our bylaw provisions to reduce our indemnification obligations to directors, officers, employees and agents.

To the extent that a claim for indemnification is brought by any of our directors or officers, it would reduce the amount of funds available for use in our business.

On February 14, 2022, we acquired a leasehold interest in approximately 409,000 rentable square feet of cGMP ISO Class 5 pharmaceutical manufacturing space in western New York (the Dunkirk Facility). This facility provides us with a state-of-the-art biotech production center that substantially expands and diversifies our existing manufacturing capacity in the U.S. See Note 13, Subsequent Events, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

We believe that our existing facilities are adequate to meet our current and future needs and that we will be able to renew existing leases and obtain additional commercial space as needed.

ITEM 3. LEGAL PROCEEDINGS.

From time to time, we may be involved in various claims and legal proceedings relating to claims arising out of our operations. We are not currently a party to any legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. We are aware of complaints that have been filed regarding the Merger, but we have not been served with any of such complaints. If we are served with any such complaints, we will assess at that time any contingencies for which we may need to reserve. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. For additional information regarding our legal proceedings, see Note 7, Commitments and Contingencies—Litigation, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis of our financial condition and results of operations should be read together with the description of our business appearing in Part I, Item 1. “Business” and the consolidated financial statements and related notes thereto in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. This discussion contains forward-looking statements as a result of many factors, including those set forth under Part I, Item 1. “Business—Forward-Looking Statements” and Item 1A. “Risk Factors,” and elsewhere in this Annual Report. These statements are based on the current expectations and assumptions of management that are subject to risks and uncertainties. Actual results could differ materially from those discussed in or implied by such forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report, particularly in Part I, Item 1A. “Risk Factors.” Except as required by law, we do not undertake any responsibility to update any of these factors or to announce publicly any revisions to any of the forward-looking statements contained in this or any document, whether as a result of new information, future events, or otherwise.

Our Business

Our broad immunotherapy and cell therapy platforms are designed to attack cancer and infectious pathogens by activating both the innate immune system—NK cells, dendritic cells, and macrophages—and the adaptive immune system—B cells and T cells—in an orchestrated manner. The goal of this potentially best-in-class approach is to generate immunogenic cell death thereby eliminating rogue cells from the body whether they are cancerous or virally infected and to ultimately establish an “immunological memory” that confers long-term benefit for the patient.

Our business is based on the foundation of multiple platforms that collectively act on the entire immune response with the goal of targeted, durable, coordinated, and safe immunity against disease. These platforms and their associated product candidates are designed to overcome the limitations of the current standards of care in oncology and infectious disease, such as checkpoint inhibitors and antiretroviral therapies. We have established one of the most comprehensive portfolios of immunotherapy and vaccine platforms, which include:

Table of Contents

We believe that our innovative approach to orchestrate and combine therapies for optimal immune system response will become a therapeutic foundation across multiple clinical indications. Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, Anktiva, our novel antibody cytokine fusion protein, has received Breakthrough Therapy and Fast Track designations in combination with BCG from the FDA for BCG-unresponsive NMIBC CIS. Based on the reported results of the trial, we have initiated discussions with the FDA to file a BLA for Anktiva (to be branded VesAnktiva for intravesical administration) plus BCG for BCG-unresponsive NMIBC CIS. Additionally, we believe that data from multiple clinical trials indicates Anktiva has broad potential to enhance the activity of therapeutic mAbs, including checkpoint inhibitors (e.g., Keytruda®), across a wide range of tumor types.

Our platforms, which include 17 first-in-human therapeutic agents, are being studied in 26 actively recruiting clinical trials—17 of which are in Phase 2 or 3 development—across 13 indications in liquid and solid tumors, including bladder, pancreatic and lung cancers. These are among the most frequent and lethal cancer types for which there are high failure rates for existing standards of care or, in some cases, no available effective treatment. In infectious disease, our pipeline currently targets such pathogens as SARS-CoV-2 and HIV. We believe SARS-CoV-2 currently lacks a vaccine that provides long-term protection against the virus, particularly its variants, while HIV affects tens of millions of people globally and currently has no known cure.

We have established GMP manufacturing capacity at scale with cutting-edge cell manufacturing expertise and ready-to-scale facilities, as well as extensive and seasoned R&D, clinical trial, and regulatory operations, and development teams.

The Merger

On December 21, 2020, we and NantCell, Inc. (formerly known as ImmunityBio, Inc., a private company) (NantCell) entered into an Agreement and Plan of Merger (the Merger Agreement), pursuant to which we and NantCell agreed to combine our businesses. The Merger Agreement provided that a wholly-owned subsidiary of the company would merge with and into NantCell (the Merger), with NantCell surviving the Merger as a wholly-owned subsidiary of the company.

113

Table of Contents

On March 9, 2021, we completed the Merger pursuant to the terms of the Merger Agreement. Under the terms of the Merger Agreement, at the effective time of the Merger (the Effective Time), each share of NantCell common stock, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time, subject to certain exceptions as set forth in the Merger Agreement, was converted automatically into a right to receive 0.8190 (the Exchange Ratio) newly issued shares of common stock, par value $0.0001 per share, of the company (Company Common Stock), with cash paid in lieu of any fractional shares. At the Effective Time, each share of the company’s common stock issued and outstanding immediately prior to the Effective Time, remained an issued and outstanding share of the combined company. At the Effective Time, each outstanding option, warrant or restricted stock unit to purchase NantCell common stock was converted using the Exchange Ratio into an option, warrant or restricted stock unit, respectively, on the same terms and conditions immediately prior to the Effective Time, to purchase shares of Company Common Stock.

Immediately following the Effective Time, the former stockholders of NantCell held approximately 71.5% of the outstanding shares of Company Common Stock and the stockholders of the company as of immediately prior to the Merger held approximately 28.5% of the outstanding shares of Company Common Stock. As a result of the Merger and immediately following the Effective Time, Dr. Patrick Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer, and his affiliates beneficially owned, in the aggregate, approximately 81.8% of the outstanding shares of Company Common Stock. Following the consummation of the Merger, the symbol for shares of the company’s common stock was changed to “IBRX.”

Accounting Treatment of the Merger

The Merger represents a business combination pursuant to Financial Accounting Standards Board Accounting Standards Codification Topic 805-50, Mergers, which is accounted for as a transaction between entities under common control as Dr. Soon‑Shiong and his affiliates were the controlling stockholders of both the company and NantCell for all of the periods presented in this report. As a result, all of the assets and liabilities of NantCell were combined with ours at their historical carrying amounts on the closing date of the Merger. We have recast our prior period financial statements to reflect the conveyance of NantCell’s common shares as if the Merger had occurred as of the earliest date of the consolidated financial statements presented in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. All material intercompany accounts and transactions have been eliminated in consolidation.

COVID-19 Pandemic

The COVID-19 pandemic continues to present a substantial public health and economic challenge around the world. Through the date of this Annual Report, we have not seen a material adverse impact to our business from the pandemic. However, given the unprecedented and continuously evolving nature of the pandemic, we cannot at this time predict the specific extent, duration, or full impact that this pandemic may have on our financial condition and results of operations, including ongoing and planned clinical trials. More specifically, the pandemic may result in prolonged impacts that we cannot predict at this time and we expect that such uncertainties will continue to exist for the foreseeable future. The impact of the pandemic on our financial performance will depend on future developments, including the duration and spread of the outbreak, impact of potential variants and the related governmental advisories and restrictions. These developments and the impact of the ongoing pandemic on the financial markets and the overall economy are highly uncertain. If the financial markets and/or the overall economy are impacted for an extended period, our results may be adversely affected. In addition, we anticipate that enrollment of patients in certain studies will likely take longer than previously forecasted and that our clinical trials may require additional time to complete which would in turn impact the timeline of BLA submissions of our product candidates and subsequent revenue generation.

These factors have been accounted for in the company’s anticipated upcoming milestones. During any such delays in our clinical trials, we will continue to incur fixed costs such as selling, general and administrative expenses and operating expenses related to our laboratory, GMP manufacturing, and office facilities.

114

Table of Contents

Many of our office-based employees have been working from home since mid-March 2020. Essential staffing levels for our research and development operations remain in place, including maintaining key personnel in our laboratory and GMP manufacturing facilities. It is likely that the pandemic and resulting mitigation efforts could have an impact in the future on our third-party suppliers who manufacture laboratory supplies required for our in-house manufacturing process, which in turn could have an impact on having sufficient clinical product supply available for our clinical trials. We have addressed this in part by ensuring that we have sufficient supplies on hand to weather interruptions in our supply chain.

We continue to monitor the impact of the COVID-19 pandemic on our business, including our clinical trials, manufacturing facilities and capabilities, and ability to access necessary resources. For a discussion of the risks presented by the COVID-19 pandemic to our results of operations and financial condition, see Part I, Item 1A. “Risk Factors.”

Operating Results

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. We have incurred net losses in each year since our inception and, as of December 31, 2021, we had an accumulated deficit of $2.0 billion. Our net losses attributable to ImmunityBio common stockholders were $346.8 million, $221.9 million, and $157.8 million for the years ended December 31, 2021, 2020 and 2019, respectively. Substantially all of our net losses resulted principally from costs incurred in connection with our ongoing clinical trials and operations, our research and development programs, and from selling, general and administrative costs associated with our operations, including stock-based compensation expense.

As of December 31, 2021, we had 587 employees. Personnel of related companies who provide corporate, general and administrative, manufacturing strategy, research and development, regulatory and clinical trial strategy and other support services under our shared services agreement with NantWorks are not included in this number. For additional information, see Note 8, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. In anticipation of the commercialization of select drug candidates, we expect to continue to incur significant expenses and increasing operating losses for the foreseeable future, which may fluctuate significantly from quarter-to-quarter and year-to-year. See “—Future Funding Requirements” below for a discussion of our anticipated expenditures and sources of capital we expect to access to fund these expenditures.

Collaboration Agreements

As we continue the development of our pipeline, we anticipate that strategic collaborations with established biopharma companies and other research-based entities will become integral to our operations and the development of novel combination therapies. These collaborations will provide ImmunityBio with a range of opportunities to leverage our partners’ expertise and capabilities to further expand the potential of our technologies and product candidates. We are currently pursuing this aspect of our business in 13 clinical trials studying our IL-15 superagonist fusion protein Anktiva in combination with complementary, approved therapies to determine if Anktiva may have broad potential to enhance the activity of those therapies, including mAbs and other standard-of-care therapeutics across a wide range of tumor types. We believe we are well positioned to become a leader in immunotherapy through the combined strength of our broad and vertically-integrated platform and complementary strategic partnerships. We may also enter into supply arrangements for various investigational agents to be used in our clinical trials. See Note 6, Collaboration and License Agreements, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for a more detailed discussion regarding our collaboration and license agreements.

Agreements with Related Parties

Our Executive Chairman, Global Chief Scientific and Medical Officer and our principal stockholder, founded and has a controlling interest in NantWorks, which is a collection of companies in the healthcare and technology space. We have entered into arrangements with NantWorks, and certain affiliates of NantWorks, to facilitate the development of new immunotherapies for our product pipeline. Affiliates of NantWorks are also affiliates of the company due to the common control by and/or common ownership interest of our Executive Chairman and Global Chief Scientific and Medical Officer.

Related-Party Promissory Notes

As of December 31, 2021, we have outstanding fixed-rate promissory notes with entities affiliated with Dr. Soon-Shiong in an aggregate amount of $306.3 million, including accrued interest. These notes bear interest at a per annum rate ranging from 3.0% to 6.0%, provide that the outstanding principal is due and payable on September 30, 2025, and accrued and unpaid interest is payable on either upon maturity or, with respect to one of the notes, on a quarterly basis beginning June 30, 2021. We may prepay the outstanding amount of any advance under such notes, together with accrued and unpaid interest, at any time, in whole or in part, without premium or penalty.

In addition, as of December 31, 2021 we have a $300.0 million variable-rate promissory note with an entity affiliated with Dr. Soon-Shiong that is due and payable on December 17, 2022. This loan bears interest at Term SOFR + 5.4%, which is compounded annually and payable quarterly commencing on March 17, 2022. As of December 31, 2021, the interest rate on this loan was 5.47%. In the event of a default on the loan (as defined in the promissory note), including if we do not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at price of $5.67 per share. There can be no assurance that we can refinance this promissory note or what terms will be available in the market at the time of refinancing. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to the refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

Immuno-Oncology Clinic, Inc.

We entered into multiple agreements with Immuno-Oncology Clinic, Inc. (the Clinic) to conduct clinical trials related to certain of our product candidates. The Clinic is a related party as it is owned by an officer of the company and NantWorks manages the administrative operations of the Clinic.

In the second quarter of 2021, based on a review of our then updated clinical trial programs post-Merger, we updated our estimates of the investigator fees for the clinical trials that were underway or planned at the Clinic. As certain programs costs are excluded from and certain services are subject to credit adjustments under the Clinic agreements, we determined the expected future fees for services to be performed were less than the carrying value of the prepaid asset on the consolidated balance sheets. As a result, we partially wrote down the value of our prepayments under the Clinic agreements and recorded approximately $1.9 million in research and development expense, on the consolidated statement of operations for the three months ended June 30,2021. In November 2021, we completed a review of alternative structures that could support our more complex clinical trial requirements and made a decision to explore a potential transition of clinical trials at the Clinic to a new structure (including contracting with a new, non-affiliated professional corporation) to be determined and agreed upon by all parties and currently planned for the first half of 2022. Based on this decision to explore a potential transition, we determined that it was more likely than not that the previously recorded prepaid asset would not result in the collection of fees for services performed by the Clinic as contemplated in the original agreements. As a result, we wrote down the remaining value of our prepaid asset and recorded approximately $2.5 million in research and development expense, on the consolidated statement of operations for the three months ended December 31, 2021.

Components of our Results of Operations

Revenue

Operating Expenses

We generally classify our operating expenses into research and development, and selling, general and administrative expenses. Personnel costs, including salaries, benefits, bonuses, and stock-based compensation expense comprise a significant component of our research and development, and selling, general and administrative expense categories. We allocate expenses associated with our facilities and information technology costs between these two categories, primarily based on the nature of each cost.

Research and Development

Research and development expense consists of expenses incurred while performing research and development activities to discover and develop our technology and product candidates. This includes conducting preclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for product candidates. We recognize research and development expenses as they are incurred. Our research and development expenses primarily consist of:

•clinical trial and regulatory-related costs;

•expenses incurred under agreements with investigative sites and consultants that conduct our clinical trials;

•expenses incurred under collaborative agreements;

•manufacturing and testing costs and related supplies and materials;

•employee-related expenses, including salaries, benefits, travel and stock-based compensation; and

•facility expenses dedicated to research and development.

We typically use our employee, consultant and infrastructure resources across our development programs. We track outsourced development costs by product candidate or development program, but we do not allocate personnel costs, other internal costs or external consultant costs to specific product candidates or development programs.

We expect our research and development expense to continue to increase significantly for the foreseeable future as we advance our product candidates through clinical development, including the conduct of our ongoing and any future clinical trials.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of any product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates.

118

Table of Contents

The costs of clinical trials may vary significantly over the life of a project owing to, but not limited to, the following:

•per patient trial costs;

•the number of sites included in the clinical trials;

•the countries in which the clinical trials are conducted;

•the length of time required to enroll eligible patients;

•the number of patients that participate in the clinical trials;

•the number of doses that patients receive;

•the cost of comparative agents used in clinical trials;

•the drop-out or discontinuation rates of patients;

•potential additional safety monitoring or other studies requested by regulatory agencies;

•the duration of patient follow-up; and

•the efficacy and safety profile of the product candidate.

We have only one product candidate, Anktiva, currently planned for a BLA submission to the FDA in the near future. However, there can be no assurance that it will be approved for commercial sale in the near term, if ever. We do not expect any of our other product candidates to be commercially available for the foreseeable future, if ever.

Selling, General and Administrative

Selling, general and administrative expense consists primarily of salaries and personnel-related costs, including employee benefits and any stock-based compensation, for employees performing functions other than research and development. This includes personnel in executive, finance, human resources, information technology, legal, and administrative support functions. Other selling, general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional fees for auditing, tax and legal services, advertising costs, expenses associated with strategic business transactions and business development efforts, obtaining and maintaining patents, consulting costs, royalties and licensing costs, and costs of our information systems.

We expect that our selling, general and administrative expense will increase for the foreseeable future as we expand operations, build out information systems and increase our headcount to support continued research activities and the development of our clinical programs. We have incurred and expect that we will continue to incur in the future, additional costs associated with operating as a public company, including costs to comply with stock exchange listing and SEC requirements, future funding efforts, corporate governance, internal controls, investor relations, disclosure and similar requirements applicable to public companies. Additionally, if and when we believe that a regulatory approval of a product candidate appears likely, we expect to incur significant increases in our selling, general and administrative expense relating to the sales and marketing of the approved product candidate.

Other Income and Expense

Other income and expense consists primarily of interest income, interest expense, unrealized gains and losses on investments in equity securities and equity-method investments, realized gains and losses on both debt and equity securities, and gains and losses on foreign currency transactions.

Income Taxes

Revenue

Revenue increased $0.3 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase was primarily driven by royalty revenue in 2021 from a sublicense agreement.

Research and Development Expense

Research and development expense increased $56.5 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase in research and development expense was primarily driven by a $32.1 million increase in compensation expense, including an $18.6 million increase in stock-based compensation expense due to new grants issued to employees and executives and a $13.5 million increase in personnel costs due to higher headcount in support of our continued research and development efforts, a $6.9 million increase in clinical trial expenses and regulatory costs related to our Anktiva and COVID-19 programs, including a $4.4 million expense associated with the write down of a prepaid asset with the Clinic, a $6.6 million increase in facilities expense, primarily related to the expansion of one of our manufacturing facilities in El Segundo, California during 2021 and increased maintenance costs at our various facilities, a $5.5 million increase in quality control and research and development-related technology expense, a $3.5 million increase in laboratory supply expense related to our COVID-19 programs ramp up and NK-92 and M-ceNK cell therapy research, and a $2.4 million increase in shared services costs to support our growth. These increases were partially offset by a $0.5 million decrease in consulting costs.

We expect our research and development expense to increase significantly for the foreseeable future as we advance our product candidates through clinical development and conduct our ongoing and planned clinical trials.

120

Table of Contents

Selling, General and Administrative Expense

Selling, general and administrative expense increased $63.9 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase in selling, general and administrative expense was primarily attributable to a $42.2 million increase in compensation expense, including a $36.4 million increase in stock-based compensation expense driven by awards granted to employees and executives and option modifications resulting in incremental stock-based compensation expense in 2021 and a $5.8 million increase in personnel costs related to higher headcount needed to support our business activities, a $19.3 million increase in professional services fees related to Merger costs, SOX compliance, the combined company audit, our recruitment and business growth strategy, various legal matters, and new system implementations, and a $3.2 million increase in insurance costs, primarily due to higher directors’ and officers’ insurance renewal rates and increased insurance coverage. These increases were partially offset by an $0.8 million decrease in shared service costs and other general and administrative expense.

Impairment of Intangible Assets

During the year ended December 31, 2020, the company recorded an impairment charge totaling $10.7 million to write down the carrying value of indefinite-lived in-process research and development intangible assets associated with the acquisition of Receptome, LLC to zero in connection with the decision to discontinue certain programs based on results gathered from preclinical data.

Other Expense, Net

Other expense, net increased $14.4 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase was due to a $6.5 million decrease in interest and investment income, driven primarily by a $6.2 million net unrealized loss from equity securities and a $0.9 million decrease in interest income, partially offset by a $0.4 million decrease in accretion of investment premiums and $0.2 million of net realized gains on investments; a $5.8 million increase in interest expense driven primarily by higher related-party borrowings; an $0.8 million loss on equity method investment; and a $1.3 million decrease in other income in our subsidiaries and foreign exchanges losses.

Comparison of the Years Ended December 31, 2020 to 2019

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” in the Management’s Discussion and Analysis of Financial Condition and Results of Operations of ImmunityBio, Inc. filed as Exhibit 99.3 to our Current Report on Form 8-K/A filed with the SEC on April 22, 2021 for a discussion of the company’s results of operations for the year ended December 31, 2020 compared to the year ended December 31, 2019.

Financial Condition, Liquidity and Capital Resources

Sources of Liquidity

Our principal sources of liquidity are our existing cash, cash equivalents, and marketable securities. We have historically invested our cash primarily in investment grade short- to intermediate-term corporate debt securities, commercial paper, government-sponsored securities, U.S. treasury securities, and foreign government bonds and classify these investments as available-for-sale. Certain of these investments are subject to general credit, liquidity and other market risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets.

121

Table of Contents

As of December 31, 2021, we had cash and cash equivalents, and marketable securities of $317.9 million compared to $97.0 million as of December 31, 2020. On April 30, 2021, we entered into an Open Market Sale Agreement (the Sale Agreement) with respect to an at-the-market (the ATM) offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $500.0 million through our sales agent. For the year ended December 31, 2021, we received net proceeds totaling $164.5 million from the issuance of 13,295,817 shares under the ATM, which we expect to use for general corporate purposes, including to progress our clinical development programs, fund other research and development activities, make capital expenditures and fund working capital. We may also use a portion of the net proceeds to license intellectual property or to make acquisitions or investments. Although we made a decision to pause our ATM offering in the fourth quarter of 2021 after our $300.0 million promissory note financing with Nant Capital and do not have an active issuance notice with our sales agent, we expect to re-initiate activity at any time based on market dynamics and/or capital requirements. As of December 31, 2021, we had $330.8 million available for future stock issuances under the ATM.

In order to complete the development of our current product candidates, and implement our business plan, we will require substantial additional funding. Furthermore, changing circumstances may cause us to increase our spending significantly faster than we currently anticipate, and we may need to raise even greater amounts of funds sooner if we choose to expand more rapidly than we presently anticipate. Moreover, our fixed expenses such as rent and other contractual commitments are substantial and are expected to increase in the future.

Uses of Liquidity

In addition to the cash used to fund our operating activities discussed in “—Future Funding Requirements” below, we will require cash to settle the following obligations:

•As of December 31, 2021, our indebtedness totals $605.6 million (consisting of related-party promissory notes and accrued and unpaid interest, less unamortized debt issuance costs), held by entities affiliated with Dr. Soon-Shiong. Of this amount, $300.0 million is due and payable on December 17, 2022. In the event of a default on the loan (as defined in the promissory note), including if we do not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at price of $5.67 per share. There can be no assurance that we can refinance this promissory note or what terms will be available in the market at the time of refinancing. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to the refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

The remaining $306.3 million is due and payable on September 30, 2025, including any accrued and unpaid interest. We may prepay the outstanding amount of any advance under such notes, together with accrued and unpaid interest, at any time, in whole or in part, without premium or penalty.

•In connection with our acquisition of Altor, we issued CVRs under which we have agreed to pay the prior stockholders of Altor approximately $304.0 million upon successful approval of the BLA, or foreign equivalent, for Anktiva by December 31, 2022 and approximately $304.0 million upon the first calendar year prior to December 31, 2026 in which worldwide net sales of Anktiva exceed $1.0 billion (with payments payable in cash or shares of our common stock or a combination thereof). Dr. Soon-Shiong and his related party hold approximately $279.5 million in the aggregate of CVRs, and they have both irrevocably agreed to receive shares of common stock in satisfaction of their CVRs. We may be required to pay the other prior Altor stockholders up to $164.2 million in settlement of the CVRs relating to the regulatory milestone and up to $164.2 million of the CVRs relating to the sales milestone should they choose to have the CVRs paid in cash instead of common stock. We may need to seek additional sources of capital to satisfy the CVR obligations if they are achieved.

•In connection with our acquisition of VivaBioCell, we are obligated to pay the former owners approximately $2.3 million of contingent consideration upon the achievement of a regulatory milestone relating to the GMP-in-a-Box technology.

Adjustments for non-cash items primarily consisted of $57.2 million in stock-based compensation expense, $14.2 million in depreciation and amortization expense, $12.5 million in non-cash interest related primarily to related-party promissory notes, $4.9 million in non-cash lease expense related to operating lease right-of-use assets, $4.6 million in unrealized losses on equity securities driven primarily by a decrease in the value of our investments, $0.8 million loss on our equity investment in the joint venture and $0.3 million in other non-cash items.

For the year ended December 31, 2020, net cash used in operating activities of $171.7 million consisted of a net loss of $224.2 million, partially offset by $36.1 million in adjustments for non-cash items and $16.4 million of cash provided by net working capital changes. Adjustments for non-cash items primarily consisted of $12.7 million in depreciation and amortization, an impairment of intangible assets totaling $10.7 million, $8.5 million in non-cash interest items related primarily to related-party promissory notes, $5.2 million in non-cash lease expense related to operating lease right-of-use assets, $2.2 million in stock-based compensation expense, a $1.4 million unrealized loss on non-marketable equity investment, and $1.2 million in other non-cash items, partially offset by a $2.9 million change in deferred tax liability, and a $2.9 million unrealized gain on equity securities. The changes in net working capital consisted primarily of increases related to $12.5 million in accrued expenses and other liabilities, $3.4 million with related parties, and $2.6 million in accounts payable, and a decrease related to $4.2 million in prepaid expenses and other current assets, partially offset by decreases related to $5.6 million in operating lease liabilities and $0.7 million in investment and other assets.

We have historically experienced negative cash flows from operating activities, with such negative cash flows likely to continue for the foreseeable future.

Investing Activities

For the year ended December 31, 2021, net cash used in investing activities was $84.9 million, which included $141.8 million of purchases of marketable debt securities and $33.6 million of purchases of property, plant and equipment, partially offset by cash inflows of $70.0 million from maturities and sales of marketable debt and equity securities, and $20.5 million in proceeds from the sale of 557 Doug St, LLC that were allocated to the book value of the property. Our investments in property, plant and equipment are primarily related to acquisitions of equipment that will be used for the manufacturing of our product candidates and expenditures related to the build out of our manufacturing facilities.

For the year ended December 31, 2020, net cash used in investing activities was $19.8 million, which included $91.8 million of purchases of marketable debt securities and $1.7 million of purchases of property, plant and equipment, partially offset by cash inflows of $73.7 million from maturities and sales of marketable debt securities.

We expect to accelerate our capital spending as we scale our GMP manufacturing capabilities, which will require significant capital for the foreseeable future.

Financing Activities

For the year ended December 31, 2021, net cash provided by financing activities was $505.4 million, which consisted of $338.5 million in net proceeds from issuances of related-party promissory notes, $164.5 million in net proceeds from the ATM offering, $5.5 million in proceeds from exercises of stock options and a $1.4 million capital contribution representing excess proceeds received over book value from the sale of 557 Doug St, LLC to an entity under common control. Net cash used in financing activities consisted of $4.1 million related to net share settlement of vested RSUs for payment of payroll tax withholding and a $0.4 million payment for contingent consideration.

For the year ended December 31, 2020, net cash provided by financing activities was $150.7 million, which consisted primarily of $86.3 million in net proceeds from an equity offering, $63.7 million in proceeds from issuances of related-party promissory notes and $1.2 million in proceeds from exercises of stock options, partially offset by $0.5 million related to net share settlement of vested RSUs for payment of payroll tax withholding.

Future Funding Requirements

From inception through the date of this Annual Report, we have generated minimal revenue, and we have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. We do not expect to generate significant revenue unless and until we obtain regulatory approval of and commercialize any of our product candidates, and we do not know when, or if, this will occur. In addition, we expect our operating expenses to significantly increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our product candidates. We have also incurred and expect that we will continue to incur in the future additional costs associated with operating as a public company as well as costs related to future fundraising efforts. In addition, subject to obtaining regulatory approval of our product candidates, we expect to incur significant commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations. We expect that our operating expenses will increase substantially if and as we:

•continue research and development, including preclinical and clinical development of our existing product candidates;

•potentially seek regulatory approval for our product candidates;

•seek to discover and develop additional product candidates;

•establish a commercialization infrastructure and scale up our manufacturing and distribution capabilities to commercialize any of our product candidates for which we may obtain regulatory approval;

•seek to comply with regulatory standards and laws;

•maintain, leverage and expand our intellectual property portfolio;

•hire clinical, manufacturing, scientific and other personnel to support our product candidates’ development and future commercialization efforts;

•add operational, financial and management information systems and personnel; and

•incur additional legal, accounting and other expenses in operating as a public company.

As a result of continuing anticipated operating cash outflows, we believe that substantial doubt exists regarding our ability to continue as a going concern without additional funding or financial support. However, we believe our existing cash, cash equivalents, and investments in marketable securities, together with capital to be raised through equity offerings (including the ATM) and our potential ability to borrow from affiliated entities, will be sufficient to fund our operations through at least the next 12 months following the issuance date of the consolidated financial statements based primarily upon our Executive Chairman and Global Chief Scientific and Medical Officer’s intent and ability to support our operations with additional funds, including loans from affiliated entities, as required, which we believe alleviates such doubt. We may also seek to sell additional equity, through one or more follow-on public offerings, or in separate financings, or obtain a credit facility. However, we may not be able to secure such external financing in a timely manner or on favorable terms. Without additional funds, we may choose to delay or reduce our operating or investment expenditures. Further, because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we may need additional funds to meet our needs sooner than planned.

We will need to obtain additional financing to fund our future operations, including completing the development and commercialization of our product candidates. Changing circumstances may cause us to increase our spending significantly faster than we currently anticipate and we may need to raise additional funds sooner than we presently anticipate. Moreover, research and development and our operating costs and fixed expenses such as rent and other contractual commitments, including those for our research collaborations, are substantial and are expected to increase in the future.

125

Table of Contents

Our future funding requirements will depend on many factors, including, but not limited to:

•progress, timing, number, scope and costs of researching and developing our product candidates and our ongoing, planned and potential clinical trials;

•time and cost of regulatory approvals;

•our ability to successfully commercialize any product candidates, if approved and the costs of such commercialization activities;

•revenue from product candidates that we may commercialize, if any, including the selling prices for such potential products and the availability of adequate third-party coverage and reimbursement for patients;

•cost of building, staffing and validating our own manufacturing facilities in the U.S., including having a product candidate successfully manufactured consistent with FDA and European Medicines Agency regulations;

•terms, timing and costs of our current and any potential future collaborations, business or product acquisitions, CVRs, milestones, royalties, licensing or other arrangements that we have established or may establish;

•time and cost necessary to respond to technological, regulatory, political and market developments; and

•costs of filing, prosecuting, maintaining, defending and enforcing any patent claims and other intellectual property rights.

Unless and until we can generate a sufficient amount of revenues, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing or distribution arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms, or at all, including but not limited to the offering, issuance and sale by us of up to a maximum aggregate amount of $500.0 million of our common stock that may be issued and sold under the ATM. Although we made a decision to pause our ATM offering in the fourth quarter of 2021 after our $300.0 million promissory note financing with Nant Capital and do not have an active issuance notice with our sales agent, we expect to re-initiate activity at any time based on market dynamics and/or capital requirements. As of December 31, 2021, we had $330.8 million available for future stock issuances under the ATM. See Note 9, Stockholders’ Deficit, of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

To the extent that we raise additional capital through the sale of equity or equity-linked securities, including convertible debt or through the ATM or other offerings, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of additional indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms unfavorable to us. We have no committed source of additional capital and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may be required to delay or reduce the scope of or eliminate one or more of our research or development programs or our commercialization efforts. Our current license and collaboration agreements may also be terminated if we are unable to meet the payment obligations under those agreements. As a result, we may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.

Contractual Obligations

We have material cash requirements to pay related party affiliates and third parties under various contractual obligations discussed below:

•We are obligated to make payments to several related party affiliates under written agreements and other informal arrangements. We are also obligated to pay interest and to repay principal under our related-party notes payable. For information regarding our financing obligations, see Note 8, Related-Party Agreements—Related-Party Notes Payable, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We are obligated to make payments under our operating leases, which primarily consist of facility leases. For information regarding our lease obligations, see Note 7, Commitments and Contingencies—Lease Arrangements, and Note 8, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•In connection with the acquisitions of Altor and VivaBioCell, we are obligated to pay contingent consideration upon the achievement of certain milestones. For information regarding our contingent consideration obligations, see Note 7, Commitments and Contingencies—Contingent Considerations Related to Business Combinations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We have contractual obligations to make payments to related party affiliates and third parties under our unconditional purchase arrangements. For information on these unconditional purchase obligations, see Note 7, Commitments and Contingencies—Contingent Consideration Related to Business Combinations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We have certain contractual commitments that are expected to be paid within one year, depending on the progress of build outs, completion of services, and the realization of milestones associated with third-party agreements. This amount totals $72.7 million and is primarily related to capital expenditures, open purchase orders as of December 31, 2021 for the acquisition of goods and services in the ordinary course of business, and near term up-front milestone payments to third parties.

•In addition, we have contractual commitments that are expected to be paid in fiscal year 2023 and beyond based on the achievement of various development, regulatory and commercial milestones for agreements with third parties. These payments may not be realized or may be modified and are contingent upon the occurrence of various future events, substantially all of which have a high degree of uncertainty of occurring. As of December 31, 2021, the maximum amount that may be payable related to these commitments is $570.7 million.

On February 14, 2022, we acquired a leasehold interest in the Dunkirk Facility. In connection with this lease, we committed to spend an aggregate of $1.52 billion on operational expenses during the initial 10-year term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. These amounts are not included in the discussion above. See “—Subse quent Events—Acquisition of cGMP ISO Class 5 Manufacturing Facility”.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our consolidated financial statements requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the valuation of equity-based awards, deferred income taxes and related valuation allowances, preclinical and clinical trial accruals, impairment assessments, contingent value right measurement and assessments, the measurement of right-of-use assets and lease liabilities, useful lives of long-lived assets, loss contingencies, fair value measurements, and the assessment of our ability to fund our operations for at least the next 12 months from the date of issuance of these financial statements. Actual results could differ from those estimates. While our significant accounting policies are more fully described in the notes accompanying our consolidated financial statements that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our consolidated financial statements:

Revenue Recognition

We have primarily generated revenues from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables and grant programs. The nonexclusive license agreements with a limited number of pharmaceutical and biotechnology companies grant them the right to use our cell lines and intellectual property for non-clinical use. These agreements generally include upfront fees and annual research license fees for such use, as well as commercial license fees for sales of the licensee products developed or manufactured using our intellectual property and cell lines. We have generated revenues from product sales of our proprietary GMP-in-a-Box bioreactors and related consumables to related parties. Additionally, we also generated revenues from grant programs.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation based on relative standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied.

Under our license agreements with customers, we typically promise to provide a license to use certain cell lines and related patents, the related know-how, and future research and development data that affect the license. We have concluded that these promises represent one performance obligation due to the highly interrelated nature of the promises. We provide the cell lines and know-how immediately upon entering into the contracts. Research and development data are provided throughout the term of the contract when and if available.

The license agreements may include non-refundable upfront payments, event-based milestone payments, sales-based royalty payments, or some combination of these. The event-based milestone payments represent variable consideration and we use the most likely amount method to estimate this variable consideration. Given the high degree of uncertainly around the achievement of these milestones, we do not recognize revenue from these milestone payments until the uncertainty associated with these payments is resolved. We currently estimate variable consideration related to milestone payments to be zero and, as such, no revenue has been recognized for milestone payments. We recognize revenue from sales-based royalty payments when or as the sales occur. On a quarterly basis, we re-evaluate our estimate of milestone variable consideration to determine whether any amount should be included in the transaction price and recorded in revenue prospectively.

We also have sold our proprietary GMP-in-a-Box bioreactors and related consumables to affiliated companies. The arrangements typically include delivery of bioreactors, consumables, and providing installation service and perpetual software licenses for using the equipment. We recognize revenue when customers obtain control and can benefit from the promised goods or services, generally upon installation of the bioreactors, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. Upfront payments and fees are recorded as deferred revenue upon receipt and recognized as revenue when we satisfy our performance obligations under these arrangements.

128

Table of Contents

Business Combinations

Business combinations are accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations (ASC 805). These standards require that the total cost of acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based on their respective fair values at the date of acquisition, with the excess purchase price recorded as goodwill. The allocation of the purchase price is dependent upon certain valuations and other studies. Acquisition costs are expensed as incurred. Estimating fair value requires us to make significant judgments and assumptions.

Contingent consideration obligations incurred in connection with a business combination are recorded at their fair values on the acquisition date and re-measured at their fair values each subsequent reporting period until the related contingencies are resolved. The resulting changes in fair values are recorded as research and development expense, on the consolidated statements of operations and comprehensive loss. Changes in fair values reflect changes to our assumptions regarding probabilities of successful achievement of related milestones, the timing in which the milestones are expected to be achieved, and the discount rate used to estimate the fair value of the obligation.

Preclinical and Clinical Trial Accruals

As part of the process of preparing the consolidated financial statements, we are required to estimate expenses resulting from obligations under contracts with vendors, clinical research organizations and consultants. The financial terms of these contracts vary and may result in payment flows that do not match the periods over which materials or services are provided under such contracts.

We estimate clinical trial and research agreement-related expenses based on the services performed, pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. In accruing clinical and research-related fees, we estimate the time period over which services will be performed and activity expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Payments made under these arrangements in advance of the receipt of the related services are recorded as prepaid expenses until the services are rendered.

Research and Development Costs

Major components of research and development costs include cash compensation and other personnel-related expenses, stock-based compensation, depreciation and amortization expense on research and development property and equipment and intangible assets, costs of preclinical studies, clinical trials costs, including CROs, and related clinical manufacturing, including CMOs, costs of drug development, costs of materials and supplies, facilities cost, overhead costs, regulatory and compliance costs, and fees paid to consultants and other entities that conduct certain research and development activities on our behalf. Costs incurred in research and development are expensed as incurred.

Included in research and development costs are clinical trial and research expenses based on the services performed pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. We record accruals for estimated costs under these contracts. When evaluating the adequacy of the accrued liabilities, we analyze the progress of the preclinical studies or clinical trials, including the phase or completion of events, invoices received, contracted costs and purchase orders. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period based on the facts and circumstances known at that time. Although we do not expect the estimates to be materially different from the amounts actually incurred, if the estimates of the status and timing of services performed differ from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular period. Actual results could differ from our estimates. We adjust the accruals in the period when actual costs become known.

Table of Contents

Stock-Based Compensation

We account for stock-based compensation under the provisions of ASC Topic 718, Compensation—Stock Compensation (ASC 718). We estimate fair value of each stock option award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes model requires the use of highly subjective assumptions, including, but not limited to, expected stock price volatility over the term of the awards and the expected term of the stock options. We measure the fair value of an equity-classified award at the grant date and recognize the stock-based compensation expense over the period of vesting on the straight-line basis for our outstanding share awards that do not contain a performance condition. For awards subject to performance-based vesting conditions, we assess the probability of the individual milestones under the award being achieved and stock-based compensation expense is recognized over the service period using the graded vesting method once management believes the performance criteria is probable of being met. If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past. For awards with service or performance conditions, we recognize the effect of forfeitures in compensation cost in the period that the award was forfeited.

Contingencies

Because of the inherent uncertainty and unpredictability related to these matters, accruals are based on what we believe to be the best information available at the time of our assessment, including the legal facts and circumstances of the case, status of the proceedings, applicable law and the views of legal counsel. Upon the final resolution of such matters, it is possible that there may be a loss in excess of the amount recorded, and such amounts could have a material adverse effect on our results of operations, cash flows or financial position. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause a change in the potential amount of the liability recorded or of the range of potential losses disclosed. As of December 31, 2021, we recorded an accrual of $7.1 million contingency related to the dissenting share obligations in accrued and other current liabilities, on our consolidated balance sheets.

See further information in Note 7, Commitments and Contingencies, of the “Notes to Consolidated Financial Statements” included in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

Recent Accounting Pronouncements

Refer to Note 2, Summary of Significant Accounting Policies, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for a discussion of recent accounting pronouncements or changes in accounting pronouncements that are of significance, or potential significance, to us.

Subsequent Events

Increase in Shares of Common Stock Authorized for Issuance

Effective February 1, 2022, ImmunityBio amended its Amended and Restated Certificate of Incorporation to increase the number of shares that the company is authorized to issue from 500,000,000 shares of common stock, $0.0001 par value per share, to 900,000,000 shares of common stock, $0.0001 par value per share. The number of shares of preferred stock, $0.0001 par value per share, that the company is authorized to issue remained unchanged at 20,000,000 shares.

Acquisition of cGMP ISO Class 5 Manufacturing Facility

On February 14, 2022, we acquired a leasehold interest in approximately 409,000 rentable square feet of cGMP ISO Class 5 pharmaceutical manufacturing space in western New York from Athenex. The facility provides us with a state-of-the-art biotech production center that substantially expands and diversifies our existing manufacturing capacity in the U.S.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our exposure to market risk for changes in interest rates relates primarily to interest earned on our cash equivalents, investments and variable interest rate debt. The primary objective of our investment activities is to preserve our capital to fund operations. A secondary objective is to maximize income from our investments without assuming significant risk. Our investment policy provides for investments in low-risk, investment-grade debt instruments. As of December 31, 2021, we had $181.1 million in cash and cash equivalents and $136.8 million in our investment portfolio. Our cash equivalents are short-term investments with maturities of 90 days or less at the time of purchase. We maintain cash deposits in FDIC insured financial institutions in excess of federally insured limits. However, we believe that we are not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. As of December 31, 2021, our investment portfolio was comprised of available-for-sale securities, and we did not hold or issue financial instruments for trading purposes.

Interest Rate Risk – Cash

With the cash discussed above, our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S interest rates. However, we do not believe a sudden change in the interest rates would have a material impact on our financial condition or results of operations due to the short-term maturities on our cash equivalents. A hypothetical 100 basis point change in interest rates during any of the periods presented would not have had a material impact on our consolidated financial statements.

Interest Rate Risk – Cash Equivalents and Investment Portfolio

We invest a portion of our cash in a number of diversified fixed and floating rate securities, consisting of marketable debt securities and debt funds that are subject to interest rate risk. Changes in the general level of interest rates can affect the fair value of our investment portfolio. If interest rates in the general economy were to rise, our holdings could lose value. At December 31, 2021, a hypothetical increase in interest rates of 100 basis points across the entire yield curve on our holdings would not have resulted in a material impact on the fair value of our portfolio.

Interest Rate Risk – Variable-Rate Debt

Our use of variable-rate debt exposes us to interest rate risk as changes in interest rates would affect interest expense. In December 2021, we entered into a $300.0 million variable interest loan that matures on December 17, 2022. This loan bears interest at Term SOFR + 5.4%. As of December 31, 2021, the interest rate on this loan was 5.47%. A 100-basis point increase in the Term SOFR rate as of December 31, 2021 would not have a material impact on our results of operations and cash flows.

Foreign Currency Exchange Risk

We are exposed to foreign currency exchange rate risk inherent in conducting business globally in numerous currencies. We contract with clinical research organizations, investigational sites and suppliers in foreign countries. We are, therefore, subject to fluctuations in foreign currency rates in connection with these agreements. We have not entered into any material foreign currency hedging contracts although we may do so in the future. From inception through the date of this Annual Report, we have not incurred any material effects from foreign currency changes on these contracts. The effect of a 10% adverse change in exchange rates on foreign currency denominated cash and payables as of December 31, 2021 would not have been material. However, fluctuations in currency exchange rates could harm our business in the future.

We are also exposed to foreign currency fluctuations related to the operations of our subsidiary in Italy whose financial statements are denominated in the Euro. We translate all assets and liabilities denominated in foreign currency into U.S. dollars using the exchange rate as of the end of the reporting period, while the operating results are translated into U.S. dollars using the average exchange rates for the reporting periods. Gains and losses resulting from translating the financial statements from our subsidiary’s functional currency to U.S. dollars are recognized as a component of other comprehensive income (loss), on the consolidated statement of comprehensive loss. Foreign currency exchange rate fluctuations affect our reported net loss and can make comparisons from period to period more difficult. Our foreign operations are not material to our operations as a whole. As such, we currently do not enter into currency forward exchange or option contracts to hedge foreign currency exposures.

Inflation Risk

Inflation may affect us by increasing our cost of labor, clinical trial, and other costs. We do not believe that inflation has had a material effect on our business, financial condition or results of operations for any period presented herein.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ImmunityBio, Inc. and Subsidiaries (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive loss, stockholders’ deficit and cash flows for each of the three years in the period ended December 31, 2021, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We have also 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, 2021, 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 March 1, 2022 expressed an unqualified 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 Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates 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 matter 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 matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.

Related party transactions and disclosures

Description of the Matter			As discussed in Note 8 to the consolidated financial statements, the Company’s Executive Chairman and Global Chief Scientific and Medical Officer has a controlling interest in certain entities with which the Company has entered into material transactions including shared services agreement with NantWorks and related party notes payable with NantWorks, Nant Capital, NantMobile, and NantCancerStemCell. Affiliates of such entities are also affiliates of the Company due to the common control of the Company’s Executive Chairman and Global Chief Scientific and Medical Officer. Assessing the sufficiency of procedures performed to identify related parties and related party transactions and determining the identified related party transactions were properly recorded, presented and disclosed was challenging due to the nature, volume and the significance of related party transactions.

How We Addressed the Matter in Our Audit			We obtained an understanding, evaluated the design and tested the operating effectiveness of internal controls over the Company’s related party process. This included testing controls over management’s identification, review and disclosure of related party transactions. We tested management’s controls over the completeness and accuracy of the related party disclosures in the consolidated financial statements. The audit procedures we performed included, among others, testing the completeness and accuracy of the listing of significant related parties identified and related party transactions provided by management, and testing the manner in which related party transactions were recorded, presented and disclosed. We performed journal entry searches of identified related parties to verify completeness and accuracy of the Company’s related party transactions. We also inspected questionnaires received from the Company’s directors and officers, read minutes of the meetings of Board of Directors and its various Committees, read employment and compensation contracts, proxy statements and other relevant filings with the Securities and Exchange Commission and other regulatory agencies that relate to the Company’s financial relationships and transactions with the Company’s executive officers and with other entities controlled by the Company’s Executive Chairman and Global Chief Scientific and Medical Officer. We confirmed the transactions and/or balances, as applicable, with the related parties including amounts payable to NantWorks under the shared service agreement and related party notes payable to Nant Capital, NantMobile, NantWorks and NantCancerStemCell. We also obtained the underlying agreements and assessed the associated accounting and disclosures. We designed and executed our tests of account balances and transaction details to assess potential effects on the Company’s identified related parties and related party transactions. We inquired of management and members of the Company’s audit committee regarding the completeness of the related party transactions identified. We have evaluated the Company’s related party disclosures included in Note 8 in relation to these matters.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of ImmunityBio, Inc. and Subsidiaries

Opinion on Internal Control Over Financial Reporting

We have audited ImmunityBio, Inc. and Subsidiaries’ internal control over financial reporting as of December 31, 2021, 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, ImmunityBio, Inc. and Subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive loss, stockholders’ deficit and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and our report dated March 1, 2022 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 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.

The goal of this potentially best-in-class approach is to generate immunogenic cell death thereby eliminating rogue cells from the body whether they are cancerous or virally infected and to ultimately establish an “immunological memory” that confers long-term benefit for the patient.

Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, Anktiva™, our novel antibody cytokine fusion protein, has received Breakthrough Therapy and Fast Track designations in combination with BCG from the U.S. Food and Drug Administration (FDA) for bacillus Calmette-Guérin (BCG)-unresponsive non-muscle invasive bladder cancer (NMIBC) carcinoma in situ (CIS). Based on the reported results of the trial, we have initiated discussions with the FDA to file a BLA for Anktiva (to be branded VesAnktiva™ for intravesical administration) plus BCG for BCG-unresponsive NMIBC CIS.

We have established Good Manufacturing Process (GMP) manufacturing capacity at scale with cutting-edge cell manufacturing expertise and ready-to-scale facilities, as well as extensive and seasoned research and development (R&D), clinical trial, and regulatory operations, and development teams.

The Merger

Under the terms of the Merger Agreement, at the effective time of the Merger (the Effective Time), each share of NantCell common stock, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time, subject to certain exceptions as set forth in the Merger Agreement, was converted automatically into a right to receive 0.8190 (the Exchange Ratio) newly issued shares of common stock, par value $0.0001 per share, of the company (Company Common Stock), with cash paid in lieu of any fractional shares. At the Effective Time, each share of the company’s common stock issued and outstanding immediately prior to the Effective Time, remained an issued and outstanding share of the combined company. At the Effective Time, each outstanding option, warrant or restricted stock unit to purchase NantCell common stock was converted using the Exchange Ratio into an option, warrant or restricted stock unit, respectively, on the same terms and conditions immediately prior to the Effective Time, to purchase shares of Company Common Stock.

We incurred costs totaling $23.3 million in connection with the Merger, consisting of financial advisory, legal and other professional fees, of which $13.0 million and $10.3 million were recorded for the years ended December 31, 2021 and 2020, respectively. Merger-related costs are reported in selling, general and administrative expense, on the consolidated statements of operations.

Accounting Treatment of the Merger

The Merger represents a business combination pursuant to Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 805-50, Mergers, which is accounted for as a transaction between entities under common control as Dr. Soon-Shiong and his affiliates were the controlling stockholders of both the company and NantCell for all of the periods presented in this report. As a result, all of the assets and liabilities of NantCell were combined with ours at their historical carrying amounts on the closing date of the Merger. We have recast our prior period financial statements to reflect the conveyance of NantCell’s common shares as if the Merger had occurred as of the earliest date of the financial statements presented. All material intercompany accounts and transactions have been eliminated in consolidation.

The following tables provide the impact of the change in reporting entity on our unaudited condensed consolidated statements of operations for the three months ended March 31, 2021 and our consolidated statements of operations for the years ended December 31, 2020 and 2019, respectively (in thousands):

2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the SEC. The consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair presentation of our financial position and results of operations.

As of December 31, 2021, the company had an accumulated deficit of $2.0 billion. We also had negative cash flows from operations of $274.4 million for the year ended December 31, 2021. The company will likely need additional capital to further fund the development of, and seek regulatory approvals for, our product candidates, and to begin to commercialize any approved products.

The consolidated financial statements have been prepared assuming the company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities that may result from the outcome of the uncertainty of our ability to continue as a going concern. As a result of continuing anticipated operating cash outflows, we believe that substantial doubt exists regarding our ability to continue as a going concern without additional funding or financial support. However, we believe our existing cash, cash equivalents, and investments in marketable securities, together with capital to be raised through equity offerings (including but not limited to the offering, issuance and sale by us of our common stock that may be issued and sold under an “at-the-market” sales agreement with Jefferies LLC (the ATM), of which we had $330.8 million available for future issuance as of December 31, 2021), and our potential ability to borrow from affiliated entities, will be sufficient to fund our operations through at least the next 12 months following the issuance date of the consolidated financial statements based primarily upon our Executive Chairman and Global Chief Scientific and Medical Officer’s intent and ability to support our operations with additional funds, including loans from affiliated entities, as required, which we believe alleviates such doubt. We may also seek to sell additional equity, through one or more follow-on public offerings, or in separate financings, or obtain a credit facility. However, we may not be able to secure such external financing in a timely manner or on favorable terms. Without additional funds, we may choose to delay or reduce our operating or investment expenditures. Further, because of the risk and uncertainties associated with the potential commercialization of our product candidates in development, we may need additional funds to meet our needs sooner than planned.

Principles of Consolidation

The consolidated financial statements include the accounts of the company and its subsidiaries in which the company has a controlling financial interest. The consolidated financial statements also include certain variable interest entities in which we are the primary beneficiary (as described in more detail below). For consolidated entities where we have less than 100% of ownership, we record net loss attributable to noncontrolling interest on the consolidated statements of operations equal to the percentage of the ownership interest retained in such entities by the respective noncontrolling parties. Any material intercompany transactions and balances have been eliminated upon consolidation.

If the entity is within the scope of the variable interest model and meets the definition of a variable interest entity (VIE), we consider whether we must consolidate the VIE or provide additional disclosures regarding our involvement with the VIE. If we determine that we are the primary beneficiary of the VIE, we will consolidate the VIE. This analysis is performed at the initial investment in the entity or upon any reconsideration event.

For entities we hold as an equity investment that are not consolidated under the VIE model, we consider whether our investment constitutes a controlling financial interest in the entity and therefore should be considered for consolidation under the voting interest model.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the valuation of equity-based awards, deferred income taxes and related valuation allowances, preclinical and clinical trial accruals, impairment assessments, contingent value right measurement and assessments, the measurement of right-of-use assets and lease liabilities, useful lives of long-lived assets, loss contingencies, fair value measurements, and the assessment of our ability to fund our operations for at least the next 12 months from the date of issuance of these consolidated financial statements. We base our estimates on historical experience and on various other market-specific and relevant assumptions that we believe to be reasonable under the circumstances. Estimates are assessed each period and updated to reflect current information, such as the economic considerations related to the impact that the ongoing coronavirus pandemic could have on our significant accounting estimates. Actual results could differ from those estimates.

Contingencies

We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We accrue for the best estimate of a loss within a range; however, if no estimate in the range is better than any other, then we accrue the minimum amount in the range. If we determine that a material loss is reasonably possible, we disclose the possible loss or range of loss, or that the amount of loss cannot be estimated at this time. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause a change in the potential amount of the liability recorded or of the range of potential losses disclosed. Moreover, we record gain contingencies only when they are realizable and the amount is known. Additionally, we record our rights to insurance recoveries, limited to the extent of incurred or probable losses, as a receivable when such recoveries have been agreed to with our third-party insurers and when receipt is deemed probable. This includes instances when our third-party insurers have agreed to pay, on our behalf, certain legal defense costs and settlement amounts directly to applicable law firms and a settlement fund.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject us to concentrations of risk consist principally of cash and cash equivalents, marketable securities, and a convertible note receivable.

We attempt to minimize credit risk associated with our cash and cash equivalents by periodically evaluating the credit quality of our primary financial institutions. Our investment portfolio is maintained in accordance with our investment policy. While we maintain cash deposits in FDIC insured financial institutions in excess of federally insured limits, we do not believe that we are exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. We have not experienced any losses on such accounts.

We also monitor the creditworthiness of the borrower of the convertible promissory note. We believe that any concentration of credit risk in its convertible note receivable was mitigated in part by our ability to convert, if necessary, at the qualifying financing event or upon a payment default into shares of the senior class of equity securities of the borrower.

Product candidates developed by us will require approvals or clearances from the FDA or international regulatory agencies prior to commercial sales. There can be no assurance that any of our product candidates will receive any of the required approvals or clearances. If we were to be denied approval or clearance or any such approval or clearance was to be delayed, it would have a material adverse impact on us.

Table of Contents

Cash, Cash Equivalents and Restricted Cash

Cash equivalents include highly liquid investments with an original maturity of three months or less from the date of purchase.

Restricted cash includes a certificate of deposit held as a substitute letter of credit for one of our leased properties. This certificate of deposit is included in other assets, on the consolidated balance sheets as the landlord is the beneficiary of the account and we are not able to access the funds during the term of the lease.

A reconciliation of cash, cash equivalents, and restricted cash is included on the consolidated statements of cash flows as of December 31, 2021, 2020 and 2019.

Marketable Securities and Other Investments

Marketable Debt Securities

We invest our excess funds in investment grade short- to intermediate-term corporate debt securities, government-sponsored securities, and foreign government bonds and classify these investments as available-for-sale. Marketable debt securities with remaining maturities of 12 months or less are classified as short-term and marketable securities with remaining maturities greater than 12 months are classified as long-term. All marketable debt securities are reported at fair value and any unrealized gains and losses are reported as a component of accumulated other comprehensive loss, on the consolidated statements of stockholders’ deficit, with the exception of unrealized losses believed to be other-than-temporary, which are recorded in interest and investment income, net, on the consolidated statements of operations. Realized gains and losses from sales of securities and the amounts, net of tax, reclassified out of accumulated other comprehensive loss, if any, are determined on a specific identification basis.

Marketable Equity Securities

Investments in mutual funds and equity securities, other than equity method investments, are recorded at fair market value, if fair value is readily determinable and any unrealized gains and losses are included in other income (expense), net, on the consolidated statements of operations. Realized gains and losses from the sale of the securities are determined on a specific identification basis and the amounts are included in other income (expense), net, on the consolidated statement of operations.

Non-Marketable Equity Securities

Prior to March 31, 2021, we owned non-marketable equity securities that were accounted for using the measurement alternative under ASC Topic 321, Investments—Equity Securities (ASC 321), because the preferred stock held by us was not considered in-substance common stock and such preferred stock did not have a readily determinable fair value. We measured the non-marketable equity investment at cost, less impairment, adjusted for observable price changes in an orderly market for an identical or similar investment of the same issuer, with such changes recognized on the consolidated statements of operations. Some factors we may consider in the impairment analysis include the extent to which the security has been in an unrealized loss position, the change in the financial condition and near-term prospects of the issuer, as well as security and industry-specific economic conditions.

Evaluating Investments for Other-than-Temporary Impairments

We periodically evaluate whether declines in fair values of our investments below their book value are other-than-temporary. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss, as well as our ability and intent to hold the investment until a forecasted recovery occurs. Additionally, we assess whether we have plans to sell the security or whether it is more likely than not we will be required to sell any investment before recovery of its amortized cost basis. Factors considered include quoted market prices, recent financial results and operating trends, implied values from any recent transactions or offers of investee securities, credit quality of debt instrument issuers, other publicly available information that may affect the value of our investments, duration and severity of the decline in value, and our strategy and intentions for holding the investment. There were no other-than-temporary impairments recorded during the years ended December 31, 2021, 2020 and 2019.

Equity Method of Accounting

In circumstances where we have the ability to exercise significant influence over the operating and financial policies of a company in which we have an investment, we utilize the equity method of accounting for recording investment activity. In assessing whether we exercise significant influence, we consider the nature and magnitude of our investment, the voting and protective rights we hold, any participation in the governance of the other company and other relevant factors such as the presence of a collaborative or other business relationship. Under the equity method of accounting, we record our share of the income or loss of the other company as gain (loss) on equity method investment, in our consolidated statements of operations.

Property, Plant and Equipment, Net

Property, plant and equipment are stated at historical cost less accumulated depreciation. Historical cost includes expenditures that are directly attributable to the acquisition of the items. All repairs and maintenance are charged to net loss during the financial period in which they are incurred. Depreciation of property, plant and equipment is calculated using the straight-line method over the estimated useful lives of the assets, as follows:


Buildings						39 years
Software						3 years
Laboratory equipment						5 to 7 years
Furniture & fixtures						5 years
IT equipment						3 years
Leasehold improvements						The lesser of the lease term or life of the asset

Upon disposal of property, plant and equipment, the cost and related accumulated depreciation are removed from the consolidated financial statements and the net amount, less any proceeds, is included in other income (expense), net, on the consolidated statements of operations.

We review impairment of property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount to the future net cash flows that the assets are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected undiscounted future cash flows arising from the assets using a discount rate determined by management to be commensurate with the risk inherent to our current business model.

Business Combinations

Contingent consideration incurred in connection with a business combination are recorded at their fair values on the acquisition date and re-measured at their fair values each subsequent reporting period until the related contingencies are resolved. The resulting changes in fair value are recorded as research and development expense, on the consolidated statements of operations and comprehensive loss. Changes in fair value reflect changes to our assumptions regarding probabilities of successful achievement of related milestones, the timing in which the milestones are expected to be achieved, and the discount rate used to estimate the fair value of the obligation.

151

Table of Contents

Common Control Transactions

Transactions between us and entities where Dr. Soon-Shiong and his affiliates are the controlling stockholders are accounted for as common control transactions whereby the net assets acquired or transferred are accounted at their carrying value. Any difference between the carrying value and consideration recognized is treated as a capital transaction. Cash consideration up to the carrying value of the net assets acquired or transferred is presented as an investing activity in our consolidated statements of cash flows. Cash consideration in excess of the carrying value of the net assets acquired or transferred is presented as a financing activity in our consolidated statements of cash flows.

Intangible Assets, Net

Intangible assets acquired in a business combination are initially recognized at their fair value on the acquisition date. The in-process research and development (IPR&D) assets are required to be classified as indefinite-lived assets and are not amortized until they become definite-lived assets, upon the successful completion of the associated research and development effort. At that time, we will evaluate whether recorded amounts are impaired and make any necessary adjustments, and then determine the useful life of the asset and begin amortization. If the associated research and development effort is abandoned, the related IPR&D assets will be written-off and an impairment charge recorded. Intangible assets are tested for impairment at least annually or more frequently if indicators of potential impairment exist.

Acquired definite-lived intangible assets are amortized using the straight-line method over their respective estimated useful lives. Intangible assets, which consisted of the cost of reacquiring a technology license during 2015, were amortized using the straight-line method over an estimated useful life of 4 years. As of December 31, 2019, our definite-lived intangible assets were fully amortized.

Patents

Patent costs, including related legal costs, are expensed as incurred and recorded in selling, general and administrative expense on the consolidated statements of operations.

Fair Value of Financial Instruments

Fair value is defined as an exit price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We use a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The hierarchy requires us to use observable inputs when available, and to minimize the use of unobservable inputs, when determining fair value.

The three tiers are defined as follows:

•Level 1—Observable inputs that reflect quoted market prices (unadjusted) for identical assets or liabilities in active markets at the measurement date. Since valuations are based on quoted prices that are readily and regularly available in an active market, the valuation of these products does not entail a significant degree of judgment. Our Level 1 assets consist of bank deposits, money market funds, and marketable equity securities.

•Level 2—Observable inputs other than quoted prices in active markets that are observable either directly or indirectly in the marketplace for identical or similar assets and liabilities. Our Level 2 assets consist of corporate debt securities including commercial paper, government-sponsored securities and corporate bonds, as well as foreign municipal securities.

•Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

152

Table of Contents

We utilize a third-party pricing service to assist in obtaining fair value pricing for our investments in marketable debt securities. Inputs are documented in accordance with the fair value disclosure hierarchy. The fair values of financial instruments other than marketable securities and cash and cash equivalents are determined through a combination of management estimates and third-party valuations.

During the years ended December 31, 2021, 2020 and 2019, no transfers were made into or out of the Level 1, 2 or 3 categories. We will continue to review the fair value inputs on a quarterly basis.

Collaboration Arrangements

We analyze our collaboration arrangements to assess whether they are within the scope of ASC Topic 808, Collaborative Arrangements (ASC 808). A collaborative arrangement is a contractual arrangement that involves a joint operating activity. These arrangements involve two or more parties who are active participants in the activity, and are exposed to significant risks and rewards dependent on the commercial success of the activity. This assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. To the extent the collaboration agreement is within the scope of ASC 808, we also assess whether the arrangement contains multiple elements that are within the scope of other accounting literature. If we conclude that some or all aspects of the agreement are distinct and represent a transaction with a customer, we account for those aspects of the arrangement within the scope of ASC Topic 606, Revenue from Contracts with Customers (ASC 606). Amounts that are owed by collaboration partners within the scope of ASC 808 are recognized as an offset to research and development expense as such amounts are incurred by the collaboration partner. The amounts owed to a collaboration partner are classified as research and development expense.

Our collaboration arrangements require us to acquire certain equipment for exclusive use in the joint operating activities. These equipment purchases do not have an alternative use and are therefore expensed as incurred within research and development expense.

Our collaboration arrangements are further discussed in Note 6, Collaboration and License Agreements.

Preclinical and Clinical Trial Accruals

Transactions with Related Parties

As outlined in Note 8, Related-Party Agreements, we have various agreements with related parties. Some are billed and settled in cash monthly. Others are billed quarterly and settled in cash the following month. Monthly accruals are made for all quarterly billing arrangements.

153

Table of Contents

Lease Obligations

For all leases other than short-term leases, at the lease commencement date, a right-of-use asset and a lease liability are recognized and included in operating lease right-of-use assets, net, and current and non-current operating lease liabilities, respectively, on the consolidated balance sheets. The right-of-use asset represents the right to use the leased asset for the lease term. At the commencement date, operating lease right-of-use assets and operating lease liabilities are determined based on the present value of lease payments to be made over the lease term. Leases are classified as either finance leases or operating leases. We do not currently have any leases classified as finance leases.

As the rate implicit in lease contracts are not readily determinable, we utilize its incremental borrowing rate as a discount rate for purposes of determining the present value of lease payments, which is based on the estimated interest rate at which we could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment. Prospectively, we will remeasure the lease liability at the net present value of the remaining lease payments using the same incremental borrowing rate that was in effect as of the lease commencement or transition date.

Operating lease right-of-use assets also include any rent paid prior to the commencement date, less any lease incentives received, and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. We determine the lease term by assuming the exercise of renewal options that are reasonably assured. The exercise of lease renewal options is at our sole discretion. Several of our leases have renewal options, however, the exercise of renewal is only assured for five of our current Good Manufacturing Practices (cGMP) facilities where we have made significant improvements or extended the lease.

We combine our lease components (e.g., fixed payments including rent, real estate taxes and insurance costs) with non-lease components (e.g., common-area maintenance costs and equipment maintenance costs) and as such, we account for lease and non-lease components as a single component. Lease expense also includes amounts relating to variable lease payments. Variable lease payments include amounts relating to common area maintenance and real estate taxes.

We do not recognize right-of-use assets and lease liabilities for qualifying short-term leases with an initial lease term of 12 months or less at lease inception. Such leases are expensed on a straight-line basis over the lease term. The lease term includes the non-cancellable period of the lease and any additional periods covered by either options to renew or not to terminate when the company is reasonably certain to exercise.

The depreciable life of operating right-of-use-assets and leasehold improvements is limited by the expected lease term.

Income Taxes

We recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. We record valuation allowances to reduce deferred tax assets to the amount we believe is more likely than not to be realized.

We recognize uncertain tax positions when the position will more likely than not be upheld on examination by the taxing authorities based solely upon the technical merits of the positions. We recognize interest and penalties, if any, related to unrecognized income tax uncertainties in income tax (expense) benefit, on the consolidated statement of operations. We did not have any accrued interest or penalties associated with uncertain tax positions as of December 31, 2021 and 2020.

Stock Repurchases

In 2015, the Board of Directors approved a share repurchase program (the 2015 Share Repurchase Program). As it is our intent for the repurchased shares to be retired, we have elected to account for the shares repurchased using the constructive retirement method. For shares repurchased in excess of par, we record the purchase price in excess of par value in accumulated deficit, on the consolidated balance sheet.

Revenue Recognition

Grant revenue is typically paid for reimbursable costs incurred over the duration of the associated research project or clinical trial and is recognized when expenses reimbursable under the grants have been incurred and payments under the grants become contractually due.

From inception through December 31, 2021, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development.

Research and Development Costs

Major components of research and development costs include cash compensation and other personnel-related expenses, stock-based compensation, depreciation and amortization expense on research and development property and equipment and intangible assets, costs of preclinical studies, clinical trials costs, including contract research organizations (CROs) and related clinical manufacturing, including contract manufacturing organizations (CMOs), costs of drug development, costs of materials and supplies, facilities cost, overhead costs, regulatory and compliance costs, and fees paid to consultants and other entities that conduct certain research and development activities on our behalf. Costs incurred in research and development are expensed as incurred.

Stock-Based Compensation

We account for stock-based compensation under the provisions of ASC Topic 718, Compensation—Stock Compensation (ASC 718). We estimate fair value of each stock option award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes model requires the use of highly subjective assumptions, including, but not limited to, expected stock price volatility over the term of the awards and the expected term of the stock options. We measure the fair value of an equity-classified award at the grant date and recognize the stock-based compensation expense over the period of vesting on the straight-line basis for our outstanding share awards that do not contain a performance condition. For awards subject to performance-based vesting conditions, we assess the probability of the individual milestones under the award being achieved and stock-based compensation expense is recognized over the service period using the graded vesting method once management believes the performance criteria is probable of being met. For awards with service or performance conditions, we recognize the effect of forfeitures in compensation cost in the period that the award was forfeited. See Note 10, Stock-Based Compensation.

Sale-Leaseback Transaction

A sale-leaseback transaction occurs when an entity sells an asset it owns and immediately leases the asset back from the buyer. The seller then becomes the lessee and the buyer becomes the lessor. When entering into a sale-leaseback transaction as a seller-lessee, the requirements in ASC Topic 606, Revenue from Contracts with Customers, and all related accounting standards updates to such Topic are applied in determining whether the transfer of an asset shall be accounted for as a sale of the asset by assessing whether it satisfies a performance obligation under the contract by transferring control of an asset. If the company transfers control of an asset to the buyer-lessor, the transfer is accounted for as a sale and the company derecognizes the transferred asset. The subsequent leaseback of the asset is accounted for in accordance with ASC Topic 842, Leases, in the same manner as any third-party lease. If the company does not transfer control of an asset to the buyer-lessor, the sale-leaseback transaction is accounted for as a financing arrangement.

In September 2021, we entered into a sale transaction with Nant Capital, LLC (Nant Capital), a related party, for a building located at 557 South Douglas Street, El Segundo, California. We subsequently leased back the building for an initial seven-year lease term with an option to extend the lease for two additional seven-year periods. There is no purchase option at the end of the lease term. Since we transferred the legal title and all benefits and risks incidental to the ownership of the property to Nant Capital, we accounted for the transfer as a sale. We have classified the leaseback of the building as an operating lease and accordingly, a right-of-use asset and an operating lease liability were established on the lease commencement date that will be amortized through the end of the lease term. See Note 8, Related-Party Agreements, for further information.

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income or loss is composed of net income (loss) and other comprehensive income (loss). Our other comprehensive income or loss consists of net unrealized gains (losses) on marketable debt securities classified as available-for-sale, net of income taxes. and foreign currency translation adjustments.

Noncontrolling Interests

Noncontrolling interests are recorded for the entities that we consolidate but are not wholly-owned by the company. Noncontrolling interests are classified as a separate component of equity on the consolidated balance sheets and consolidated statements of stockholders’ deficit. Additionally, net loss attributable to noncontrolling interests is reflected separately from consolidated net loss on the consolidated statements of operations and the consolidated statements of stockholders’ deficit. We record the noncontrolling interests’ share of loss based on the percentage of ownership interest retained by the respective noncontrolling interest holders. Noncontrolling interests recorded on the consolidated financial statements result from the company’s share of GlobeImmune, Inc. (GlobeImmune), of which we controlled 69.1%, and Immunotherapy NANTibody, LLC (NANTibody), of which we controlled 60.0% as of December 31, 2021, 2020 and 2019. Noncontrolling interest stockholders are common stockholders.

GlobeImmune was determined to be a VIE as it does not have sufficient equity investment at risk to finance its operations without additional subordinated financial support and we are deemed the primary beneficiary of GlobeImmune and, accordingly, consolidates GlobeImmune into the consolidated financial statements under the VIE model. The company also supports GlobeImmune through a promissory note agreement, in which the company provides advances to GlobeImmune from time to time up to $6.0 million with a per annum interest rate of five percent (5%). As of December 31, 2021 and 2020, there were no outstanding advances due from GlobeImmune under the promissory note agreement.

GlobeImmune recognized $0.2 million of revenues for the year ended December 31, 2019, and recognized $0.7 million, $2.0 million and $7.7 million of operating expenses for the years ended December 31, 2021, 2020 and 2019, respectively. The consolidated balance sheets include approximately $0.8 million and $0.5 million of total assets and $0.0 million and $0.3 million of total liabilities as of December 31, 2021 and 2020, respectively, related to GlobeImmune.

In addition, the company held a 68.5% ownership interest in Precision Biologics, Inc. (Precision) arising from a preferred stock investment. The company ended its investment in Precision pursuant to a final settlement agreement approved by the court in 2019. Under the terms of the settlement agreement, the company deconsolidated the related assets, liabilities and noncontrolling interests of Precision. The disposition of this investment resulted in a reduction of $18.4 million in noncontrolling interests for the year ended December 31, 2019. See Note 7, Commitments and Contingencies—Litigation, for additional information.

Foreign Currencies

We have operations and holds assets in Italy and South Korea. The functional currency of the subsidiary in Italy is the Euro, based on the nature of the transactions occurring within this entity, and accordingly, assets and liabilities of this subsidiary are translated into U.S. dollars at exchange rates prevailing as of the balance sheet dates, while the operating results are translated into U.S. dollars using the average exchange rates for the period correlating with those operating results. Adjustments resulting from translating the financial statements of the foreign subsidiary into U.S. dollars are recorded as a component of other comprehensive income (loss), on the consolidated statements of comprehensive loss. Transaction gains and losses are recorded in other income (expense), net, on the consolidated statements of operations.

Basic and Diluted Net Loss per Share of Common Stock

Basic net loss per share is calculated by dividing the net loss attributable to ImmunityBio common stockholders by the weighted-average number of common shares outstanding for the period. Diluted loss per share is computed by dividing net loss attributable to ImmunityBio common stockholders by the weighted-average number of common shares, including the number of additional shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive.

For all periods presented, potentially dilutive securities are excluded from the computation of fully diluted loss per share as their effect is anti-dilutive. The following table details those securities that have been excluded from the computation of potentially dilutive securities:


	As of December 31,
	2021	2020	2019
Outstanding stock options	4,124,930	4,996,284	6,080,483
Outstanding RSUs	6,515,889	466,842	1,155,808

Total	12,278,819	7,101,126	8,874,291

Amounts in the table above reflect the common stock equivalents of the noted instruments, including awards issued under the NantKwest 2015 Equity Incentive Plan (the 2015 Plan), the NantKwest 2014 Equity Incentive Plan (the 2014 Plan), and awards issued under the NantCell, Inc. 2015 Stock Incentive Plan (the NC 2015 Plan) that, in the case of December 31, 2021, were outstanding immediately prior to the Effective Time of the Merger and in the case of December 31, 2020 and 2019 have been adjusted to include the combined NC 2015 Plan and NantCell warrants then outstanding (in both cases adjusted using the Exchange Ratio of 0.8190). See Note 10, Stock-Based Compensation, for further information.

Segment and Geographic Information

We operate in one reporting segment focused on creating the next generation of immunotherapies to address serious unmet needs within oncology and infectious diseases. Our chief executive officer (CEO) is the chief operating decision-maker (CODM) of the company, and manages and allocates resources to our operations on a company-wide basis. Consistent with this decision-making process, our CEO uses consolidated, single-segment financial information for purposes of evaluating performance, forecasting future-period financial results, allocating resources and setting incentive targets.

Recent Accounting Pronouncements

Application of New or Revised Accounting Standards – Adopted

In November 2018, the FASB issued Accounting Standards Update, or ASU, No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 (ASU 2018-18), which clarifies when certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606, “Revenue from Contracts with Customers” when the counterparty is a customer. In addition, the update precludes an entity from presenting consideration from a transaction in a collaborative arrangement as customer revenue if the counterparty is not a customer for that transaction. We adopted ASU 2018-18 in the quarter ended March 31, 2020 on a prospective basis. The adoption did not have an impact on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019‑12, Simplifying the Accounting for Income Taxes, or ASU 2019‑12. The amendments removed the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (e.g., discontinued operations or other comprehensive income), and the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. ASU 2019‑12 also amends other aspects of accounting for income taxes to help simplify and promote consistent application of U.S. GAAP. We early adopted ASU 2019‑12 effective January 1, 2020, and it did not have a material impact on our consolidated financial statements

In June 2016, the FASB issued Accounting Standards Update (ASU) 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which requires credit losses on most financial instruments measured at amortized cost and certain other financial instruments be measured using an expected credit loss model. Under this model, entities are required to estimate credit losses over the entire contractual term of the financial instrument from the date of initial recognition of the instrument. The company adopted this guidance on the first day of the company’s fourth quarter of fiscal 2021. The adoption of ASU 2016-13 did not have any impact on our consolidated financial statements.

Application of New or Revised Accounting Standards – Not Yet Adopted

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes the separation models for convertible instruments with cash or beneficial conversion features. Instead, entities will account for convertible debt instruments wholly as debt, unless certain other conditions are met. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The adoption of the new standard is not expected to have a material impact on the company’s financial position or results of operations upon adoption.

Other recent authoritative guidance issued by the FASB (including technical corrections to the ASC), the American Institute of Certified Public Accountants, and the SEC during the three months ended December 31, 2021 did not, or are not expected to, have a material effect on our consolidated financial statements.

3. Financial Statement Details

Property, Plant and Equipment, Net

Property, plant and equipment, net, consist of the following (in thousands):




	As of December 31,

Less: Accumulated depreciation and amortization	53,074		41,862
Property, plant and equipment, net	$	82,863	$	72,541

In September 2021, we entered into a sale transaction with Nant Capital, a related party, for a building located at 557 South Douglas Street, El Segundo, California. We subsequently leased back the building for an initial seven-year lease term with an option to extend the lease for two additional seven-year periods. The net proceeds from the transaction totaled $21.9 million and the net carrying value of the building was $20.5 million at the time of the transaction. We accounted for the transfer as a sale of an asset to an entity under common control, recorded the transfer at book value and recognized the excess of net consideration over carrying book value of $1.4 million as a capital contribution received from Nant Capital. See Note 8, Related-Party Agreements, for further information.

Depreciation and amortization expense related to property, plant and equipment totaled $14.2 million, $12.7 million and $14.0 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Intangible Assets, Net

As of December 31, 2021 and 2020, the company only had indefinite-lived IPR&D intangible assets, which were obtained from business acquisitions. During 2020, we determined to discontinue the LMP1 and LMP/IPS programs based on the results gathered from the preclinical data during the third quarter of 2020. As a result, the carrying value of the IPR&D relating to the LMP1 and LMP/IPS program was written down to zero and we recorded an impairment charge of $10.7 million on the consolidated statement of operations. No such charges were recorded during the years ended December 31, 2021 and 2019.

Convertible Note Receivable

In 2016, we executed a convertible promissory note with Riptide Bioscience, Inc., or Riptide, and advanced Riptide a principal amount of $5.0 million. The note bears interest at a per annum rate of five percent (5%). The original term of the promissory note requires that the entire unpaid principal amount and all unpaid accrued interest shall become fully due and payable upon the earlier of (i) the three (3) year anniversary of the issuance date, and (ii) when we accelerate the maturity of the note upon the occurrence of an event of default. In the event of qualified financing, the outstanding principal amount and unpaid accrued interest automatically convert into the most senior class of preferred stock sold in such qualified financing at a 25% discount to the price per share paid for such preferred stock. In addition, in the event of a change in control, we have the option to be paid in cash or to convert, immediately prior to the closing of such transaction, the outstanding indebtedness into Riptide’s most senior class of equity securities at a 25% discount to the price per share paid for such equity securities in such transaction.

Table of Contents

Concurrent with the transaction, we entered into an exclusive license agreement with Riptide to obtain worldwide exclusive rights, with the right to sublicense, certain know-how related to RP-182, RP-233 and RP-183. We are required to pay a single-digit royalty on net sales of the licensed products on a country-by-country basis. Pursuant to the license agreement, we are also required to make cash milestone payments upon successful completion of certain clinical, regulatory and commercial milestones up to an aggregate amount of $47.0 million for the first three indications of the licensed product with a maximum payment amount of $100.0 million.

In 2019, we and Riptide entered into a first amendment to the convertible promissory note. Under the agreement, we extended the maturity of the promissory note to the earlier of, a) the later of, i) the completion of non-clinical IND enabling studies by the company, or ii) December 31, 2020; and b) when we accelerate the maturity of the note upon the occurrence of an event of default. No other terms and conditions of the promissory note were modified. Concurrently, we also entered into a first amendment to the exclusive license agreement with Riptide and extended the achievement dates for certain clinical trial milestones related to the licensed products. This option for receiving a 25% discount was determined to have an immaterial value at inception and life to date of the note, as the probability of a future qualifying event is remote. All other terms and conditions of the license agreement continued in full force and effect. This promissory note is still outstanding as of December 31, 2021. The convertible note receivable balance was $6.4 million and $6.1 million, which included accrued interest of $1.4 million and $1.1 million as of December 31, 2021 and 2020, respectively

We evaluated our securities for other-than-temporary impairment, and we did not recognize any other-than-temporary impairment losses for the years ended December 31, 2021, 2020 and 2019.

Realized gains and losses on sales of available-for-sale marketable debt securities were not significant for the years ended December 31, 2021, 2020 and 2019.

Marketable Equity Securities

We held investments in marketable equity securities with readily determinable fair values of $6.7 million and $6.3 million as of December 31, 2021 and 2020, respectively. Unrealized losses recorded on these securities totaled $4.6 million and $0.3 million for the years ended December 31, 2021 and 2019, and an unrealized gain recorded on these securities totaled $1.6 million for the year ended December 31, 2020, respectively, in interest and investment (loss) income, net, on the consolidated statements of operations. We recorded a realized gain totaling $0.2 million from sales of marketable equity securities in interest and investment (loss) income, net, on the consolidated statement of operations for the year ended December 31, 2021.

Non-Marketable Equity Securities

In 2017, we participated in a Series B convertible preferred stock financing and invested $8.5 million in Viracta Therapeutics, Inc. (Viracta), a clinical-stage drug development company with whom we have an exclusive worldwide license to develop and commercialize one of their proprietary drug candidates, which was initially recorded at cost. In 2018, we purchased additional convertibles notes totaling $0.7 million, which could be converted into preferred stock of Viracta under certain circumstances. Effective in early 2019, the notes, together with accrued interest then outstanding, were converted to Series B preferred stock resulting in an increase to our investment in Viracta’s Series B convertible preferred stock of $0.8 million. In 2019, we exercised warrants to acquire 253,120 shares of Viracta common stock.

We have elected to apply the measurement alternative under ASC 321, pursuant to which we measure our investment in Viracta at cost, less impairment, adjusted for observable price changes in an orderly market for an identical or similar investment of the same issuer, with such changes recognized on the consolidated statements of operations.

On December 31, 2020, we reduced the carrying value by $1.4 million due to the observable price change, which was included in other income (expense), net, on the consolidated statements of operations. As of December 31, 2020, the carrying value of our investment in Viracta, which is reflected in non-marketable equity investment, on the consolidated balance sheets, totaled $7.8 million.

In February 2021, Viracta merged with Sunesis Pharmaceuticals, Inc. (Sunesis), a public company. In connection with this transaction, our preferred stock investment in Viracta was converted into 1,562,604 shares of Viracta common stock effective February 25, 2021. The fair value of investment is accounted as marketable equity securities and is reflected in marketable securities, on the consolidated balance sheets, totaled $5.7 million as of December 31, 2021.

6. Collaboration and License Agreements

Collaboration Agreements

National Cancer Institute

2015 NCI CRADA

In May 2015, Etubics Corporation (Etubics) entered into a Cooperative Research and Development Agreement (CRADA) with the U.S. Department of Health and Human Services (HHS) as represented by the National Cancer Institute (NCI) of the National Institutes of Health (NIH) to collaborate on the preclinical and clinical development of an adenovirus technology expressing tumor-associated antigens for cancer immunotherapy. In January 2016, we acquired all of the outstanding equity interests in Etubics and Etubics became a wholly-owned subsidiary.

Effective January 2018, our subsidiary NantCell assumed the CRADA and it was amended to cover a collaboration for the preclinical and clinical development of our proprietary yeast-based Tarmogens expressing tumor-associated antigens and proprietary adenovirus technology expressing tumor-associated antigens for cancer immunotherapy. Pursuant to the CRADA, the NCI provides scientific staff and other support necessary to conduct research and related activities as described in the CRADA.

During the term of the CRADA, we were required to make annual payments of $0.6 million to the NCI for support of research activities. We made payments of $0.6 million in each of the years ended December 31, 2021 and 2020, respectively, and recorded $0.6 million in research and development expense, on the consolidated statements of operations for the years ended December 31, 2021 and 2020.

In November 2021, NantCell entered into a third amendment to the CRADA, which was effective as of March 16, 2021. The principal changes effected by the third amendment are the following: (i) assignment of the CRADA from NantCell to ImmunityBio; (ii) modification of the research plan; (iii) extension of the CRADA term through May 2026; and (iv) an increase in funding for a total of $1.3 million per year, payable in semi-annual installments from 2022 through 2025.

Pursuant to the updated CRADA research plan, NCI and ImmunityBio will collaborate on the preclinical and clinical development of ImmunityBio’s proprietary adenovirus platform expressing tumor-associated antigens; proprietary yeast platform expressing tumor-associated antigens; proprietary agent Anktiva and derivatives, agent N-808 and derivatives, and/or TxM product candidates; proprietary recombinant NK cells and mAbs; proprietary RNA vaccines and adjuvants; and other proprietary agents owned or controlled by ImmunityBio as contemplated in the research plan, for cancer immunotherapy.

In accordance with the terms of the amended CRADA, the company is required to make an additional $0.7 million payment within 30 days of the execution date in addition to a $0.6 million payment to the NCI for support of research activities during 2021. We made a payment of $0.7 million and recorded an additional $0.5 million for the third amendment in research and development expense, on the consolidated statement of operations for the year ended December 31, 2021.

National Institute of Deafness and Communication Disorders

2021 NIDCD CRADA

In February 2021, we entered into a CRADA with HHS as represented by the National Institute of Deafness and Communication Disorders (NIDCD) of the NIH to conduct collaborative analysis of human clinical trial samples from clinical trials using our proprietary recombinant NK cells and/or mAbs for preclinical development in monotherapy and in combination immunotherapies. The CRADA has a two-year term commencing on February 22, 2021 and expiring on February 22, 2023. During the term of the agreement, we are required to provide $0.1 million per year to the NIDCD for support of the research activities. We made a payment of $0.1 million during the year ended December 31, 2021.

Under any of the CRADAs, any party may unilaterally terminate the agreement by providing timely advance written notice to the other party before the desired termination date.

Pursuant to the terms of the CRADAs, we have an option to elect to negotiate an exclusive or non-exclusive commercialization license to any inventions discovered in the performance of any of the CRADAs. The parties jointly own any inventions and materials that are jointly produced by employees of both parties in the course of performing activities under the CRADAs.

Amyris Joint Venture

In December 2021, ImmunityBio and Amyris, Inc. (Amyris) entered into a 50:50 joint venture arrangement and formed a new limited liability company to conduct the business of the joint venture, to accelerate the commercialization of a next-generation COVID-19 vaccine utilizing IDRI’s RNA vaccine platform to which Amyris holds a license. As part of the limited liability agreement, we agreed to contribute $1.0 million in cash and priority access to our manufacturing capacity for the joint venture product. Amyris contributed $1.0 million in cash and rights to its license agreement with IDRI for the IDRI RNA platform for the field of COVID-19. The value of the manufacturing access right and the license right was determined by the board of directors of the joint venture to be $9.0 million, respectively. Both parties agreed to enter into a separate manufacturing and supply agreement and a sublicense agreement within 90 days of the execution of the joint venture agreement. Both parties agreed to make additional capital contributions in cash, in proportion to their respective interests, as determined by the board of directors of the joint venture (two members appointed by us and two members appointed by Amyris). The joint venture agreement stipulates the initial terms for equal representation in the management of the newly-formed joint venture. We considered the joint venture entity as a VIE and determined that we are not the primary beneficiary of the VIE. We accounted for the joint venture using the equity method of accounting, and recorded our 50% share of the net loss from the joint venture totaling $0.8 million in other expense, net, on the consolidated statement of operations for the year ended December 31, 2021.

Infectious Disease Research Institute

In May 2021, we entered into two license agreements with the Infectious Disease Research Institute (IDRI) pursuant to which we received a license to certain patents and know-how relating to IDRI’s (i) adjuvant formulations for the treatment, prevention and/or diagnosis of SARS-CoV-2 (the IDRI Adjuvant Formulation License Agreement) and (ii) RNA vaccine platform as further described below (the IDRI RNA License Agreement). Under both agreements, we were obligated to pay one-time, non-creditable, non-refundable upfront cash payments totaling $2.0 million. In addition, under the IDRI Adjuvant Formulation License Agreement we owe IDRI milestone payments to a total of up to $2.5 million based on the achievement of certain development and regulatory milestones for the first licensed product and royalties on annual net sales of licensed products on a country-by-country and product-by-product basis of a low-single digit percentage, subject to certain royalty-reduction provisions. Under these agreements, we made a $2.0 million upfront payment and recognized $2.0 million in research and development expense, on the consolidated statement of operations, and no milestone fees were incurred for the year ended December 31, 2021.

In connection with the license agreements, in May 2021 we also entered into a sponsored research agreement (SRA) with IDRI pursuant to which we will fund continued research of at least $2.0 million per year, payable in four equal quarterly installments each year until May 2024, or such year of earlier termination. For the year ended December 31, 2021, we recorded $1.2 million in research and development expense, on the consolidated statement of operations related to the SRA.

Viracta License Agreement

In 2017, we entered into an agreement with Viracta under which we were granted exclusive worldwide rights to Viracta’s Phase 2 drug candidate, VRx-3996 (nanatinostat), for use in combination with our platform of NK cell therapies. In consideration for the license, we are obligated to pay Viracta mid-single digit percentage royalties on net sales of licensed products for therapeutic use and milestone payments ranging from $10.0 million to $25.0 million up to an aggregate maximum of $100.0 million for various regulatory approvals and cumulative net sales levels. We may terminate the agreement, at our sole discretion, in whole or on a product by product and/or country by country basis, at any time upon 90 days’ prior written notice. In addition, either party may terminate the agreement in the event of a material breach or for bankruptcy of the other party. To date, we have not had incurred any royalty or milestone payment obligations under this agreement, including during the years ended December 31, 2021, 2020 and 2019.

7. Commitments and Contingencies

Contingent Consideration Related to Business Combinations

VivaBioCell, S.p.A.

In April 2015, NantWorks, LLC (NantWorks), a related party, acquired a 100% interest in VivaBioCell, S.p.A. (VivaBioCell) through its wholly-owned subsidiary, VBC Holdings, LLC, (VBC Holdings) for $0.7 million, less working capital adjustments. In June 2015, NantWorks contributed its equity interest in VBC Holdings to the company, in exchange for cash consideration equal to its cost basis in the investment. VivaBioCell develops bioreactors and products based on cell culture and tissue engineering in Italy.

In connection with our acquisition of VBC, we are obligated to pay the former owners contingent consideration upon the achievement of certain milestones related to the GMP-in-a-Box technology. A clinical milestone totaling $0.8 million was earned by the former owners of VivaBioCell, of which $0.4 million was paid during the year ended December 31, 2021. The remaining $0.4 million was accrued as of December 31, 2021 and is expected to be paid in 2022. If the regulatory milestone is achieved, we are obligated to pay approximately $2.3 million.

Altor BioScience Corporation

In connection with the 2017 acquisition of Altor BioScience Corporation (Altor), we issued contingent value rights (CVRs) under which we agreed to pay the prior stockholders of Altor approximately $304.0 million upon successful approval of the Biologics License Application (BLA) or foreign equivalent, for Anktiva by December 31, 2022 and approximately $304.0 million upon the first calendar year before December 31, 2026 in which worldwide net sales of Anktiva exceed $1.0 billion (with amounts payable in cash or shares of our common stock or a combination thereof). Dr. Soon-Shiong and his related party hold approximately $279.5 million in the aggregate of CVRs and they have both irrevocably agreed to receive shares of the company’s common stock in satisfaction of their CVRs. We may be required to pay the other prior Altor stockholders up to $164.2 million in settlement of the CVRs relating to the regulatory milestone and up to $164.2 million of the CVRs relating to the sales milestone should they choose to have the CVRs paid in cash instead of common stock. As the transaction was recorded as an asset acquisition, future CVR payments will be recorded when the corresponding events are probable of achievement or the consideration becomes payable.

Litigation

Altor BioScience, LLC Litigation

In 2017, NantCell announced it had entered into a definitive merger agreement to acquire Altor BioScience Corporation. An action captioned Gray v. Soon-Shiong, et al. was filed in Delaware Chancery Court by plaintiffs Clayland Boyden Gray (Gray) and Adam R. Waldman. The plaintiffs, two minority stockholders, asserted claims against the company and other defendants for (1) breach of fiduciary duty and (2) aiding and abetting breach of fiduciary duty and filed a motion to enjoin the merger. The court denied the motion and permitted the merger to close.

Subsequent to the close of the merger, in 2017 the plaintiffs (joined by two additional minority stockholders, Barbara Sturm Waldman and Douglas E. Henderson (Henderson)) filed a second amended complaint, asserting claims for (1) appraisal; (2) quasi-appraisal; (3) breach of fiduciary duty; and (4) aiding and abetting breach of fiduciary duty. The defendants moved to dismiss the second amended complaint, raising grounds that included a “standstill” agreement under which defendants maintained that Gray and Adam R. Waldman and Barbara Strum Waldman (the Waldmans) agreed not to bring the lawsuit.

Table of Contents

In a second action, Dyad Pharmaceutical Corporation (Dyad) filed a petition in Delaware Chancery Court for appraisal in connection with the merger. Respondent moved to dismiss the appraisal petition in 2018, arguing in part that the petition was barred by the same “standstill” agreement. In 2018, the court heard oral arguments on the motions to dismiss in both consolidated cases and converted the motions to dismiss into motions for summary judgment with regard to the “standstill” agreement argument (the Converted Motions).

The court issued an oral ruling in 2019 that dismissed certain claims and dismissed Altor BioScience from the action. The following claims remained: (a) the appraisal claims by all plaintiffs and Dyad (against Altor BioScience, LLC), and (b) Henderson’s claims for breach of fiduciary duty and aiding and abetting breach of fiduciary duty.

In 2019, the court issued a written order implementing its ruling on the Converted Motions (the Implementing Order). In the Implementing Order, the court confirmed that all fiduciary duty claims brought by Gray, both individually and as trustee of the Gordon Gray Trust f/b/o C. Boyden Gray, were dismissed. Gray and the Waldmans filed answers denying the counterclaims and asserting defenses. The plaintiffs then moved for leave to file a third amended complaint to add two former Altor stockholders as plaintiffs and a fiduciary duty claim on behalf of a purported class of former Altor stockholders, which the defendants opposed.

In 2020, the court granted the plaintiffs’ motion, and the plaintiffs filed the third amended complaint. In 2020, the defendants answered the third amended complaint and asserted counter claims against the plaintiffs. The defendants are seeking damages for attorneys’ fees and costs incurred as a result of the breaches of the “standstill” agreements discussed above and of stockholder releases. The plaintiffs filed an answer denying the counterclaims and asserting defenses. Trial was set to commence on August 8, 2022, but the parties have received notice that the Vice Chancellor assigned to the case is retiring, and there may be a new trial date.

The shares of the former Altor stockholders seeking appraisal met the definition of dissenting shares under the merger agreement and were not entitled to receive any portion of the merger consideration at the closing date. However, these dissenting shares will automatically be converted to receive the portion of the merger consideration they were entitled to, on the later of the closing date or when the stockholder withdraws or loses the right to demand appraisal rights. Payment for dissenting shares will be on the same terms and conditions originally stated in the merger agreement.

As of December 31, 2021 and 2020, we had accrued $7.1 million and $6.8 million, respectively, related to the dissenting share obligations. The accrued amount represents the estimated low-end of the range of currently estimated payout amounts in accordance with ASC Topic 450, Contingencies, after considering the reasonable outcomes for settling the dissenting stockholder dispute along with any accrued statutory interest. We cannot reasonably estimate a range of loss or likelihood of loss beyond the amounts recorded for dissenting shares as of December 31, 2021, as the dissenting stockholders have not yet provided a quantified value of their claim and, therefore, an upper end of the range of loss cannot be determined. Discovery is ongoing, and the class certification motion relating to the putative class has not yet been decided. We reassess the reasonableness of the recorded amount at each reporting period. We believe the claims lack merit and intend to continue defending the case vigorously.

Sorrento Therapeutics, Inc. Litigation

Sorrento Therapeutics, Inc. (Sorrento), derivatively on behalf of NANTibody, filed an action in the Superior Court of California, Los Angeles County (the Superior Court) against the company, Dr. Soon-Shiong and Charles Kim. The action alleged that the defendants improperly caused NANTibody to acquire IgDraSol, Inc. from our affiliate NantPharma, LLC (NantPharma) and sought to have the transaction undone and the purchase amount returned to NANTibody. In 2019, we filed a demurrer to several causes of action alleged in the Superior Court action, and Sorrento filed an amended complaint, eliminating Mr. Kim as a defendant and dropping the causes of action we had challenged in our demurrer.

Table of Contents

Sorrento filed a related arbitration proceeding (the Cynviloq arbitration) against Dr. Soon-Shiong and NantPharma; the company is not named in the Cynviloq arbitration. In 2020, the Superior Court granted Dr. Soon-Shiong’s request for a preliminary injunction barring Sorrento from pursuing claims against him in the Cynviloq arbitration. Sorrento then filed the claims it had previously asserted in arbitration against Dr. Soon-Shiong in the Superior Court, and at Sorrento’s request, the arbitrator entered an order dismissing Sorrento’s claims against Dr. Soon-Shiong in the Cynviloq arbitration. The hearing in the Cynviloq arbitration commenced in June 2021, and continued with breaks until early October 2021. The parties are now engaged in post-hearing briefing, and it is expected that summations will be scheduled in mid-July 2022.

Also in 2019, the company and Dr. Soon-Shiong filed cross-claims in the Superior Court action against Sorrento and its Chief Executive Officer Henry Ji, asserting claims for fraud, breach of contract, breach of the covenant of good faith and fair dealing, tortious interference with contract, unjust enrichment, and declaratory relief. Our claims allege that Dr. Ji and Sorrento breached the terms of an exclusive license agreement between the company and Sorrento related to Sorrento’s antibody library and that Sorrento did not perform its obligations under the exclusive license agreement. The Superior Court ruled that the company’s claims should be pursued in arbitration and that Dr. Soon-Shiong’s claims could be pursued in Superior Court.

In 2019, the company, along with NANTibody, filed an arbitration against Sorrento and Dr. Ji asserting our claims relating to the exclusive license agreement. In 2020, Sorrento sent letters purporting to terminate the exclusive license agreement with the company, and an exclusive license agreement with NANTibody and demanding the return of its confidential information and transfer of all regulatory filings and related materials. As required pursuant to the exclusive license agreements, both parties must engage in good-faith negotiations before attempting to invoke any termination provision contained in the agreement. Notwithstanding such negotiations, Sorrento sent a letter purporting to terminate the exclusive license agreements, maintaining the negotiations did not reach a successful resolution. We believe we have cured any perceived breaches during the 90-day contractual cure period provided under the agreements. Sorrento filed counterclaims against the company and NANTibody in the arbitration and requested leave to file a dispositive motion. The hearings in the NANTibody arbitration commenced in April 2021 and concluded in early August 2021. After post-hearing briefing was concluded, the parties were notified on November 30, 2021 that the arbitrator in the NANTibody arbitration had passed away. A substitute arbitrator was appointed on February 25, 2022, and the parties will work with the substitute arbitrator to conclude the proceedings. We intend to prosecute our claims, and to defend the claims asserted against us, vigorously. An estimate of the possible loss or range of loss cannot be made at this time.

Shenzhen Beike Biotechnology Co. Ltd. Arbitration

In 2020, we received a Request for Arbitration before the International Chamber of Commerce, International Court of Arbitration. The arbitration relates to a license, development, and commercialization agreement that Altor entered into with Beike in 2014, which agreement was amended and restated in 2017, pursuant to which Altor granted to Beike an exclusive license to use, research, develop and commercialize products based on Anktiva in China for human therapeutic uses. In the arbitration, Beike is asserting a claim for breach of contract under the license agreement. Among other things, Beike alleges that we failed to use commercially reasonable efforts to deliver to Beike materials and data related to Anktiva. Beike is seeking specific performance, or in the alternative, damages for the alleged breaches. On September 25, 2020, the parties entered into a standstill and tolling agreement under which, among other things, the parties affirmed they will perform certain of their obligations under the license agreement by specified dates and agreed that all deadlines in the arbitration are indefinitely extended. The standstill agreement may be terminated by any party on ten calendar days’ notice, and upon termination, the parties will have the right to pursue claims arising from the license agreement in any appropriate tribunal. The parties have been providing periodic updates to the International Chamber of Commerce confirming a stay of all proceedings during the standstill. Given that this action remains at the pleading stage and no discovery has occurred, it remains too early to evaluate the likely outcome of the case or to estimate any range of potential loss. We believe the claims lack merit and intend to defend the case vigorously and that we may have counterclaims.

Fox Chase Cancer Center Foundation Litigation

In, 2020, ImmunityBio filed a declaratory judgment lawsuit in the Superior Court for San Diego County, California, naming Fox Chase Cancer Center Foundation and Institute for Cancer Research (ICR) as the defendants (hereafter collectively Fox Chase). This litigation relates to the license with Fox Chase and includes various intellectual property rights (the 2004 License). Our initial court filing requested the Court to find that we have not breached material obligations under the 2004 License and that Fox Chase has not and cannot terminate the 2004 License. Fox Chase filed a Cross-Complaint raising a patent inventorship challenge and moved the case to federal court. On June 4, 2021, the federal court separated the parties’ claims, and returned ImmunityBio’s declaratory judgment claims back to the San Diego County court but retained the patent inventorship challenge. On November 18, 2021, we reached a settlement with Fox Chase related to the 2004 License and agreed to a mechanism for addressing the patent inventorship dispute. There was no financial impact to the company with respect to this settlement.

Litigation Related to the Merger with ImmunityBio, Inc.

In connection with the Merger with NantCell, Inc. (formerly known as ImmunityBio, Inc., a private company), a Delaware corporation, via a wholly-owned subsidiary of NantKwest (the Merger Sub), seven complaints have been filed as individual actions in United States District Courts. Three complaints have been filed in the United States District Court for the District of Delaware against NantKwest and its directors and are captioned Hargett v. NantKwest, Inc., et al., 1:21‑cv‑00197 (filed February 11, 2021) (the Hargett Complaint), Franchi v. NantKwest, Inc., et al., 1:21‑cv‑00218 (filed February 16, 2021) (the Franchi Complaint), and Gross v. NantKwest, Inc., et al., 1:21‑cv‑00223 (filed February 17, 2021) (the Gross Complaint). One complaint has been filed in the United States District Court for the Southern District of New York and is captioned Leaman v. NantKwest, Inc., et al., 1:21‑cv‑01351 (filed February 16, 2021) (the Leaman Complaint). Two complaints have been filed in the United States District Court for the Southern District of California and are captioned Weiss v. NantKwest, Inc., et al., 3:21‑cv‑00280 (filed February 16, 2021) (the Weiss Complaint) and Carlisle v. NantKwest, Inc., et al., 3:21‑cv‑00304 (filed February 19, 2021) (the Carlisle Complaint). One complaint has been filed in the United States District Court for the Eastern District of New York and was captioned Shenk v. NantKwest, Inc., et al., 1:21‑cv‑00871 (filed February 18, 2021) (the Shenk Complaint, and collectively with the Hargett Complaint, the Franchi Complaint, the Gross Complaint, the Leaman Complaint, the Weiss Complaint, and the Carlisle Complaint, the Merger Actions). The Shenk Complaint was voluntarily dismissed on March 10, 2021. The Franchi Complaint was voluntarily dismissed on May 6, 2021. The Leaman Complaint was voluntarily dismissed on May 7, 2021. The Hargett Complaint and the Gross Complaint were both voluntarily dismissed on May 18, 2021. The Hargett Complaint and the Gross Complaint also brought claims against ImmunityBio, Inc. and Merger Sub. The Merger Actions generally allege that the Definitive Proxy Statement filed with the SEC on February 2, 2021 misrepresents and/or omits certain purportedly material information relating to financial projections, analysis performed by the financial advisor to NantKwest’s Special Committee, alleged past engagements of the Special Committee’s financial advisor and industry consultant, and the terms of the engagement of such consultant. The Merger Actions assert violations of Section 14(a) of the Securities Exchange Act of 1934, as amended (the Exchange Act), and Rule 14a-9 promulgated thereunder against all defendants and violations of Section 20(a) of the Exchange Act against NantKwest’s directors. The Merger Actions seek, among other things, an injunction enjoining the stockholder vote on the Merger and the consummation of the Merger unless and until certain additional information is disclosed to NantKwest’s stockholders, costs of the action, including plaintiffs’ attorneys’ fees and experts’ fees, and other relief the Court may deem just and proper. Neither the stockholder vote on the Merger nor the Merger were enjoined and occurred on March 8 and March 9, 2021, respectively. The company cannot predict the outcome of the Merger Actions. The company believes the Merger Actions are without merit and the company and the individual defendants intend to vigorously defend against the Merger Actions and any subsequently filed similar actions. If additional similar complaints are filed, absent new or significantly different allegations, the company will not necessarily disclose such additional filings.

Securities Litigation

In 2016, a putative securities class action complaint captioned Sudunagunta v. NantKwest, Inc., et al., 16-cv-01947 was filed in federal district court for the Central District of California related to our restatement of certain interim financial statements for the periods ended June 30, 2015 and September 30, 2015. A number of similar putative class actions were filed in federal and state courts in California. The plaintiffs asserted causes of action for alleged violations of Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder. The plaintiffs sought unspecified damages, costs and attorneys’ fees, and equitable/injunctive or other relief on behalf of putative classes of persons who purchased or acquired our securities during various time periods from July 28, 2015 through March 11, 2016.

In 2018, the district court granted the plaintiffs’ motions for class certification and to strike plaintiffs’ claims under the Exchange Act and Rule 10b-5. The parties informed the Ninth Circuit that they had reached a settlement in principle, moved to stay in appellate proceedings, and notified the district court that they had reached a settlement in principle. The plaintiffs then filed an unopposed motion for preliminary approval of the settlement and notice to class members.

A final approval hearing was held, and the district court granted final approval and entered judgment on May 31, 2019. Under the terms of the settlement, we paid $12.0 million to the plaintiffs as a full and complete settlement of the litigation. The company was responsible for $1.2 million of the settlement amount, which was recognized in selling, general and administrative expense, on the consolidated statement of operations for the year ended December 31, 2018, while the remaining $10.8 million was funded by our insurance carriers under our directors’ and officers’ insurance policy. The settlement amount was deposited into a settlement fund during the year ended December 31, 2019.

Stipulation of Settlement

In 2019, following approval by our Board of Directors, we entered into a settlement agreement (the Stipulation of Settlement) with three stockholders of the company, each of whom had submitted a stockholder demand for the Board of Directors to take action to remedy purported harm to the company resulting from certain alleged wrongful conduct concerning, among other things, disclosures about Dr. Soon-Shiong’s compensation and a related-party lease agreement. The Stipulation of Settlement called for us to adopt certain governance changes, and for the three stockholders to file a stockholder derivative action in the Superior Court of the State of California, County of San Diego, followed by an application for court approval of the Stipulation of Settlement. The court entered an order preliminarily approving the Stipulation of Settlement. Pursuant to the Stipulation of Settlement, we provided stockholders with notice of the settlement and the final settlement hearing.

Under the terms of the Stipulation of Settlement, which received final approval by the court on August 9, 2019, the company paid attorney fees of $0.5 million to the plaintiffs as part of the settlement. Of that amount, we were responsible for half, which was recognized in selling, general and administrative expense, on the consolidated statement of operations for the year ended December 31, 2019, while the other half was funded by our insurance carrier. The settlement amount was deposited into a settlement fund during the year ended December 31, 2019.

Precision Biologics, Inc. Settlement

In 2015, the company invested $50.0 million in cash in Precision in exchange for 41.0 million shares of Precision’s series A preferred stock (representing a 68.5% ownership interest in Precision at the time of the investment). In 2017, a Precision stockholder filed a complaint captioned Feldman v. Soon-Shiong, et al. (individually and derivatively on behalf of Precision), and filed an amended complaint against the company and other defendants asserting claims for breach of contract (including the implied covenant of good faith and fair dealing), tortious interference with contract, breach of the fiduciary duty of loyalty, the appointment of a custodian, fraud in the inducement, and violation of state “Blue Sky” laws. The defendants moved to dismiss the amended complaint. In 2018, the court heard oral arguments and issued an opinion granting in part, and denying in part, defendants’ motion.

Table of Contents

In 2019, the parties completed fact discovery other than depositions (and certain document discovery subsequently ordered by the court). The parties agreed in principle to the terms of a settlement and filed a settlement stipulation with the court. A settlement hearing before the court was held, and the court approved the settlement, which was finalized on July 20, 2019. Under the terms of the settlement, the company ended its investment in Precision. As part of the deconsolidation, we withdrew $29.3 million in cash from the investment on our books and transferred $2.5 million to Precision. In addition to $20.2 million of accumulated losses recorded in prior years, which represented the expected losses associated with giving up our preferred stock ownership and absorbing losses arising from the deconsolidation, we recorded a $0.9 million loss associated with the final settlement for the year ended December 31, 2019.

Lease Arrangements

We lease property in multiple facilities across the U.S. and Italy, including facilities located in El Segundo and Culver City, CA that are leased from related parties. Substantially all of our operating lease right-of-use assets and operating lease liabilities relate to facilities leases. See Note 8, Related-Party Agreements, for additional information about our related-party leases.

Our leases generally have initial terms ranging from two to ten years and often include one or more options to renew. These renewal terms can extend the lease term from one to seven years, and are included in the lease term when it is reasonably certain that we will exercise the option.

Unconditional Purchase Obligations

Unconditional purchase obligations are defined as an agreement to purchase goods or services that are enforceable and legally binding (non-cancelable, or cancelable only in certain circumstances). In the normal course of business, we enter into unconditional purchase obligation arrangements with a CMO to reserve manufacturing slots in its cGMP manufacturing facility for the manufacture and supply of cGMP batches per FDA and European Medicines Agency (EMA) regulations for commercial use. The total amount of future non-cancelable purchase commitments related to the manufacture of cGMP batches is $3.5 million and $3.5 million for the years ending December 31, 2022 and 2023, respectively.

We estimate our total unconditional purchase obligation commitment (for contracts with terms in excess of one year) as of December 31, 2021, at $2.6 million. Payments by year are estimated as follows: 2022 ($2.1 million) and 2023 ($0.5 million). These commitments relate primarily to hosted software license subscription fees and related implementation costs and our pro-rata share is passed-through to us without any markup under the shared services agreement with NantWorks, as further discussed in Note 8, Related-Party Agreements. The purchase obligation amounts do not represent the entire anticipated purchases in the future, but represent only those items for which we are contractually obligated. The majority of our goods and services are purchased as needed, with no unconditional commitment. For this reason, these amounts do not provide an indication of our expected future cash outflows related to purchases.

Commitments

We did not enter into any significant contracts or material unconditional purchase commitments during the year ended December 31, 2021, other than those disclosed in these consolidated financial statements.

Our Executive Chairman, Global Chief Scientific and Medical Officer, and principal stockholder founded and has a controlling interest in NantWorks, which is a collection of companies in the healthcare and technology space. As described below, we have entered into arrangements with NantWorks, and certain affiliates of NantWorks, to facilitate the development of new genetically modified NK cells for our product pipeline. Affiliates of NantWorks are also affiliates of the company due to the common control by and/or common ownership interest of our Executive Chairman and Global Chief Scientific and Medical Officer.

NantWorks

Under the NantWorks shared services agreement executed in November 2015, but effective August 2015, NantWorks, a related party, provides corporate, general and administrative, manufacturing strategy, research and development, regulatory and clinical trial strategy, and other support services. We are charged for the services at cost plus reasonable allocations of employee benefits, facilities and other direct or fairly allocated indirect costs that relate to the employees providing the services. For the years ended December 31, 2021, 2020 and 2019, we recorded $4.4 million, $6.0 million and $6.8 million, respectively, in selling, general and administrative expense, and $0.4 million, $2.0 million and $1.5 million, respectively, of expense reimbursements under this arrangement in research and development expense, on the consolidated statements of operations. These amounts exclude certain general and administrative expenses provided by third-party vendors directly for our benefit, which were reimbursed to NantWorks based on those vendors’ invoiced amounts without markup by NantWorks.

As of December 31, 2021 and 2020, we owed NantWorks a net amount of $1.1 million and $10.7 million, respectively, for all agreements between the two affiliates, which is included in due to related parties, on the consolidated balance sheets. We also recorded $2.2 million and $1.0 million of prepaid expenses for services that have been passed through to the company from NantWorks as of December 31, 2021 and 2020, respectively, which are included in prepaid expenses and other current assets, on the consolidated balance sheets.

In November 2015, we entered into a facility license agreement with NantWorks for approximately 9,500 rentable square feet of office space in Culver City, California, which was converted to a research and development laboratory and a cGMP manufacturing facility. The initial license was effective from May 2015 through December 2020. The base rent for the initial lease term was $47,000 per month, with annual increases of 3% beginning in January 2017. In September 2020, we amended this agreement to extend the term of this lease through December 31, 2021. Commencing January 1, 2021, the base rent increased by 3% to approximately $54,500 per month. Subsequent to December 31, 2021, the lease term will automatically renew on a month-to-month basis, terminable by either party with at least 30 days’ prior written notice to the other party. Lease expense for this facility totaling $0.7 million, $0.6 million and $0.6 million for the years ended December 31, 2021, 2020 and 2019, respectively, was recorded in research and development expense, on the consolidated statements of operations.

Immuno-Oncology Clinic, Inc.

Beginning in 2017, we entered into multiple agreements with Immuno-Oncology Clinic, Inc. (the Clinic) to conduct clinical trials related to certain of our product candidates. The Clinic is a related party as it is owned by an officer of the company and NantWorks manages the administrative operations of the Clinic. Prior to June 30, 2019, one of our officers was an investigator or sub-investigator for all of our trials conducted at the Clinic.

In July 2019, we entered into a new agreement with the Clinic (the Clinic Agreement), which became effective on July 1, 2019. The Clinic Agreement, as amended on March 31, 2020, covers clinical trial and research-related activities on a non-exclusive basis relating to existing clinical trials, commenced prior to July 1, 2019, and prospective clinical trials and research projects. The Clinic Agreement also specifies certain services and related costs that are excluded from the Clinic Agreement. Prior to commencing any work under the Clinic Agreement, the parties have agreed to execute written work orders setting forth the terms and conditions related to specific services to be performed, including financial terms. For clinical trials that commenced prior to July 1, 2019, excluding certain NantCell trials not covered by the agreement, fees incurred for services performed after July 1, 2019 are covered under the Clinic Agreement and applied towards the below-mentioned prepayments. The Clinic Agreement allows for automatic renewal and additional extensions beyond the initial one-year term.

In consideration of the services to be performed under the Clinic Agreement, as amended on March 31, 2020, we agreed to make payments of up to $7.5 million to the Clinic, of which $3.8 million and $1.9 million were paid in July 2019 and October 2019, respectively. As amended, a conditional payment of $1.9 million shall be due and payable at such time, if any, that the payments made in July 2019 and October 2019 have been earned by the Clinic through the performance of services. On a quarterly basis, our prepayment is increased by a nominal interest credit computed in accordance with terms specified in the Clinic Agreement.

The Clinic may terminate this agreement upon each anniversary date upon 60 days prior written notice and reimbursement in full to us of any outstanding unearned balance of the prepayments, provided that any such termination by the Clinic will not apply with respect to any work orders still in effect at the time of such termination.

We executed a clinical trial work order under the Clinic Agreement for an open-label, Phase 1 study of PD‑L1 t‑haNK™ for infusion in subjects with locally advanced or metastatic solid cancers. In July 2020, but effective on June 22, 2020, we and NantCell executed a clinical trial work order under our existing master agreement with the Clinic for an open-label, randomized, comparative Phase 2 study of our proprietary IL‑15 superagonist (Anktiva) and aldoxorubicin hydrochloride (aldoxorubicin) and our PD‑L1 t‑haNK with standard-of-care chemotherapy versus standard-of-care chemotherapy for patients with locally advanced or metastatic pancreatic cancer treated as first-line, second-line, or third-line or greater, in three separate cohorts, respectively.

During the year ended December 31, 2021, ImmunityBio executed multiple work orders under an existing master agreement with the Clinic. Under these work orders, the parties agreed that the Clinic would serve as a site for the following multi-site clinical trials:

•A Phase 1B open-label study of the safety, reactogenicity, and immunogenicity of prophylactic vaccination with second-generation E1/E2B/E3-deleted adenoviral-COVID-19 in normal healthy volunteers;

•A Phase 1B open-label study of the safety, reactogenicity, and immunogenicity of subcutaneously and orally administered prophylactic vaccination with second-generation E1/E2B/E3-deleted adenoviral-COVID-19 in normal healthy volunteers;

•A Phase 1 study of the safety, reactogenicity, and immunogenicity of subcutaneously- and orally-administered supplemental spike & nucleocapsid-targeted COVID‑19 vaccine to enhance T cell-based immunogenicity in participants who have already received a vaccine authorized for emergency use;

•A Phase 1 study of the safety, reactogenicity, and immunogenicity of a supplemental spike & nucleocapsid-targeted COVID‑19 vaccine to enhance T cell-based immunogenicity in participants who have already received a vaccine authorized for emergency use; and

•A Phase 1 open-label study of M‑ceNK cells in subjects with locally advanced or metastatic solid tumors.

In the second quarter of 2021, based on a review of our then updated clinical trial programs post-Merger, we updated our estimates of the investigator fees for the clinical trials that were underway or planned at the Clinic. As certain programs costs are excluded from and certain services are subject to credit adjustments under the Clinic agreements, we determined the expected future fees for services to be performed were less than the carrying value of the prepaid asset on the consolidated balance sheets. As a result, we partially wrote down the value of our prepayments under the Clinic agreements and recorded approximately $1.9 million in research and development expense, on the consolidated statement of operations for the three months ended June 30, 2021. In November 2021, we completed a review of alternative structures that could support our more complex clinical trial requirements and made a decision to explore a potential transition of clinical trials at the Clinic to a new structure (including contracting with a new, non-affiliated professional corporation) to be determined and agreed upon by all parties and currently planned for the first half of 2022. Based on this decision to explore a potential transition, we determined that it was more likely than not that the previously recorded prepaid asset would not result in the collection of fees for services performed by the Clinic as contemplated in the original agreements. As a result, we wrote down the remaining value of our prepaid asset and recorded approximately $2.5 million in research and development expense, on the consolidated statement of operations for the three months ended December 31, 2021.

For the years ended December 31, 2021, 2020 and 2019, we incurred $1.6 million, $0.9 million and $1.1 million in research and development expense, on the consolidated statements of operations related to the Clinic Agreement. As of December 31, 2021 and 2020, we owed the Clinic $0.5 million and $0.3 million, respectively, for services excluded from the Clinic Agreement. As of December 31, 2020, we had prepaid balances related to the Clinic Agreement of $4.7 million.

9. Stockholders’ Deficit

Stock Authorized for Issuance

As of December 31, 2021, the company was authorized to issue up to 500,000,000 shares of its common stock, par value $0.0001 per share, and 20,000,000 shares of our preferred stock, par value $0.0001 per share. As of December 31, 2021, there were 397,830,044 shares of our common stock outstanding (excluding 163,800 shares held by a majority owned subsidiary of the company that are treated as treasury shares for accounting purposes).

Effective February 1, 2022, ImmunityBio amended and restated its Amended and Restated Certificate of Incorporation to increase the number of shares of common stock that the company is authorized to issue from 500,000,000 shares to 900,000,000 shares. The number of shares of preferred stock that the company is authorized to issue remains unchanged at 20,000,000 shares. See Note 13, Subsequent Events.

Common Stock Issued in Connection with the Merger

Under the terms of the Merger Agreement, at the Effective Time of the Merger, each share of NantCell common stock, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time, subject to certain exceptions as set forth in the Merger Agreement, was converted automatically into a right to receive 0.8190 newly issued shares of common stock, par value $0.0001 per share, resulting in the issuance of approximately 273.7 million shares of Company Common Stock. From and after the Effective Time, all of such NantCell shares ceased to be outstanding, were canceled and ceased to exist. At the Effective Time, each share of our common stock issued and outstanding immediately prior to the Effective Time, remained an issued and outstanding share of the combined company.

Since the Merger was accounted for as a transaction between entities under common control, the outstanding shares presented on the consolidated financial statements assume that NantCell outstanding common stock was converted into shares of Company Common Stock for all periods presented, and in connection with the conversion, those shares of common stock were recorded at the company’s par value of $0.0001 per share.

Stock Repurchases

2015 Share Repurchase Program

In 2015, the Board of Directors approved the 2015 Share Repurchase Program, which allows our CEO or chief financial officer (CFO), to repurchase on behalf of the company, from time to time in the open market or in privately negotiated transactions, up to $50.0 million of our outstanding shares of common stock, exclusive of any commissions, markups or expenses. The timing and amounts of any purchases were and will continue to be based on market conditions and other factors, including price, regulatory requirements and other corporate considerations. The 2015 Share Repurchase Program does not require the purchase of any minimum number of shares and may be suspended, modified, or discontinued at any time without prior notice. We have financed, and expect to continue to finance, the purchases with existing cash balances. Shares repurchased under this program are formally retired through approval of the Board of Directors upon repurchase.

No shares of our common stock were repurchased during the years ended December 31, 2021 and 2020 under the program. During the year ended December 31, 2019, we repurchased 473,586 shares at a cost of $0.5 million. Since the plan’s inception, we have repurchased a total of 6,403,489 shares at a total cost of $31.7 million. As of December 31, 2021, $18.3 million remained authorized for repurchase under the program.

During the year ended December 31, 2019, we entered into a stock transfer agreement with a stockholder and purchased 204,750 shares of our common stock at a price of $9.77 per share for an aggregate purchase price of $2.0 million in cash. All shares repurchased in this transaction were retired and reduced the number of shares issued and outstanding.

Open Market Sale Agreement

On April 30, 2021, we entered into an Open Market Sale Agreement (the Sale Agreement) with respect to an ATM offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $500.0 million through our sales agent. We pay our sales agent a commission of up to 3.0% of the gross sales proceeds of any shares of our common stock sold through them under the Sale Agreement, and also have provided them with customary indemnification and contribution rights.

During the year ended December 31, 2021, we received net proceeds totaling $164.5 million from the issuance of 13,295,817 shares under the ATM, which we expect to use for general corporate purposes, including to progress our clinical development programs, fund other research and development activities, make capital expenditures and fund working capital. We may also use a portion of the net proceeds to license intellectual property or to make acquisitions or investments. As of December 31, 2021, we had $330.8 million available for future stock issuances under the ATM.

We are not obligated to sell any shares and may at any time suspend solicitation and offers under the Sale Agreement. The Sale Agreement may be terminated by us at any time given written notice to the sales agent for any reason or by the sales agent at any time by giving written notice to us for any reason or immediately under certain circumstances, and shall automatically terminate upon the issuance and sale of all of the shares.

Other Sales of Common Stock

During the year ended December 31, 2020, the company closed an underwritten public offering of an aggregate of 8,521,500 shares of common stock, which included 4,811,500 shares issued to the public at a price of $9.50 per share (including 1,111,500 shares sold to the public upon full exercise of the underwriters’ option to purchase additional shares at a public offering price of $9.50 per share), less underwriting discounts and commissions, and 3,710,000 shares issued to Dr. Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer, at a price of $12.12 per share, less underwriting discounts and commissions. All of the shares were offered by the company. Including the underwriters’ option exercise, the aggregate gross proceeds from the offering were $90.7 million, before deducting underwriting discounts, commissions and other offering costs of $4.4 million.

During the year ended December 31, 2019, the company sold 2,047,500 shares of common stock at a price of $14.66 per share to a private party and received net proceeds totaling $30.0 million.

10. Stock-Based Compensation

2015 Equity Incentive Plan

In 2015, the Board of Directors adopted, and our stockholders approved, the 2015 Plan. The 2015 Plan, as amended, permits the grant of incentive stock options to the company’s employees, and the grant of non-statutory stock options, restricted stock, RSUs, stock appreciation rights, performance units and performance shares to the company’s employees, directors and consultants. In addition, the number of shares reserved for future grant under the 2015 Plan include shares subject to stock options granted under the 2014 Plan that expire or terminate without having been exercised in full and shares issued pursuant to awards granted under the 2014 Plan that are forfeited to or repurchased by us (provided that the maximum number of shares that may be added to the 2015 Plan pursuant to this provision is approximately 503,493 shares as of December 31, 2021). Pursuant to the Merger, we assumed 7,121,110 RSUs (adjusted for the Exchange Ratio of 0.8190) issued under the 2015 NC Plan.

As of December 31, 2021, the 2015 Plan is the only equity plan available for grant of equity awards to employees, directors and consultants of the company. As of December 31, 2021, a total of approximately 5.0 million shares were available for future grants under the 2015 Plan.

	$	57,181	$	2,187	$	3,421

On March 18, 2021, the Board of Directors approved to modify certain non-qualified stock options that were assumed in the Merger and otherwise would have expired during a period when the grantees were legally restricted from exercising these awards. The expiration date of these options was extended to thirty (30) days following the effective date of Post-Effective Amendment No. 1 on Form S-3 to our Form S-4 Registration Statement. We recorded an incremental stock-based compensation expense of approximately $2.7 million for this stock option modification.

On March 29, 2021, in connection with the resignation of two former independent directors, the Board of Directors approved the acceleration of vesting of 83,333 shares of unvested stock options of the former directors on the date of their respective resignations. The modified options are exercisable for ninety (90) days after the date of the modification. We recorded an incremental stock-based compensation expense of approximately $2.3 million for this stock option modification.

The stock option modifications were measured as the excess of the fair value of the modified awards over the fair value of the original awards immediately before the modifications. The incremental stock-based compensation was recorded in selling, general and administrative expense, on the consolidated statement of operations for the year ended December 31, 2021.

On February 5, 2021, the Compensation Committee of the Board of Directors granted Richard Adcock, our chief executive officer, a stock option award (the Option Grant) to purchase 750,000 shares of our common stock pursuant to our 2015 Plan. The Option Grant has an exercise price of $23.72 per share, the closing price as reported on the Nasdaq on the date of grant. In addition, the Option Grant shall vest according to the following vesting schedule: one-third of the Option Grant (i.e., 250,000 options) shall vest in equal installments on each of the first, second, and third anniversaries of the date of grant, such that all shares shall be fully vested on the third anniversary of the date of grant, subject to Mr. Adcock remaining in continuous service as defined in the 2015 Plan through the applicable vesting dates. This grant of equity awards to Mr. Adcock was made in connection with his appointment as chief executive officer of the company, which was effective as of October 26, 2020, and was modified from the recommended equity grant described in Mr. Adcock’s offer of employment as of that date.

On May 3, 2021, the Compensation Committee of the Board of Directors granted each of our newly-appointed independent directors a non-qualified stock option award to purchase 21,873 shares of our common stock pursuant to the 2015 Plan at an exercise price of $17.24 per share, the closing price as reported on the Nasdaq on the date of grant. The shares subject to the award will vest in three (3) equal installments on each of the first, second and third anniversary date of their appointment to the Board of Directors, such that the award will be fully vested on the third anniversary date in 2024, subject to the director continuing to be a service provider as defined in the 2015 Plan through the applicable vesting dates.

On June 10, 2021, the Compensation Committee of the Board of Directors granted our Chairman and each of the independent members of our Board of Directors a non-qualified stock option award to purchase 26,064 shares of our common stock pursuant to the 2015 Plan at an exercise price of $14.91 per share, the closing price as reported on the Nasdaq on the date of grant. The shares subject to the award will vest 100% on the earlier to occur of June 10, 2022 or the date immediately preceding the 2022 annual meeting of stockholders, subject to the recipient continuing to be a service provider as defined in the 2015 Plan through the applicable vesting date. These grants were made in connection with the re-election of our Executive Chairman (who then later also became our Global Chief Scientific and Medical Officer), and independent directors to the Board of Directors at the 2021 Annual Meeting of Stockholders.

As of December 31, 2021, the unrecognized compensation cost related to outstanding stock options was $11.8 million, which is expected to be recognized over a remaining weighted-average period of 2.0 years.

The total intrinsic value of stock options exercised during the year ended December 31, 2021 was $21.3 million. Cash proceeds received from stock option exercises during the year ended December 31, 2021 was $5.4 million.

Table of Contents

As of December 31, 2020, a total of 4,345,497 vested and exercisable shares were outstanding.

The fair value of stock options issued was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:


	Year Ended December 31,
	2021			2020			2019
Expected life (in years)	5.9 years			5.5 years			N/A
Risk-free interest rate	0.7		%	0.4		%	N/A
Volatility factor	101.0		%	96.8		%	N/A
Dividend yield	0.0		%	0.0		%	N/A
Weighted-average grant date fair value	$	16.80		$	4.64		N/A

The expected term was estimated using the average of the contractual term and the weighted-average vesting term of the options. The risk-free interest rate was based on the U.S. Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The expected volatility was estimated based on the historical volatility of our common stock. The assumed dividend yield was based on our expectation of not paying dividends for the foreseeable future.

Restricted Stock Units

The following table summarizes RSU activity during the year ended December 31, 2021:


	Number of Units	Weighted- Average Grant Date Fair Value
Nonvested balance at December 31, 2020	466,842	$	2.52
Granted	8,665,942	$	23.27
Vested	(873,058)	$	19.61
Forfeited/canceled	(1,743,837)	$	24.77
Nonvested balance at December 31, 2021	6,515,889	$	21.88

As of December 31, 2021, there was $112.1 million of unrecognized stock-based compensation expense related to RSUs that is expected to be recognized over a weighted-average period of 3.5 years. The total intrinsic value of RSUs vested during the year ended December 31, 2021 was $12.2 million.

We may grant RSUs to both employees and directors of the company and to employees of related parties that provide shared services to the company under our shared services agreement with NantWorks as discussed in Note 8, Related-Party Agreements. The grant date fair value of an RSU equals the closing price of our common stock on the date of grant.

On February 5, 2021, the Compensation Committee of the Board of Directors granted Mr. Adcock two awards totaling 400,000 RSUs (each an RSU Award and collectively, the RSU Awards) of our common stock pursuant to the 2015 Plan. The RSU Awards are comprised of two separate awards, one settled by issuing 150,000 shares of our common stock and the other to be settled by issuing 250,000 shares of our common stock upon vesting. The first RSU Award vested immediately on the date of grant with the company retaining shares equal in value to the company’s tax withholding obligations. The second RSU Award will vest according to the following schedule: one-third (i.e., 83,333) of the shares subject to the RSU Award shall vest in equal annual installments on each of the first, second and third anniversaries of the date of grant, such that all shares shall be fully vested on the third anniversary of the date of grant, subject to Mr. Adcock remaining in continuous service as defined in the 2015 Plan through the applicable vesting dates. This grant of equity awards to Mr. Adcock was made in connection with his appointment as chief executive officer of the company, which was effective as of October 26, 2020, and was modified from the recommended equity grant described in Mr. Adcock’s offer of employment as of that date.

On March 4, 2021, prior to the Merger, NantCell awarded 7,121,110 RSUs (adjusted for the Exchange Ratio of 0.8190) to certain employees, consultants and/or service providers of NantCell and its affiliates, pursuant to the NC 2015 Plan. These RSU awards were subject to a performance condition in connection with a “Liquidity Event”, defined as either (i) NantCell’s registration of shares for issuance on a securities offering or (ii) the closing of a corporate transaction. In addition, the vesting of certain performance-based RSU grants accelerates upon obtaining approval by the FDA of a BLA or equivalent application for approval of Anktiva for use in the treatment of non-muscle-invasive bladder cancer. These performance-based RSUs are also subject to service conditions and are scheduled to cliff vest on the last date of each tranche as defined by the individual grant agreements. On March 9, 2021, we completed the Merger with NantCell, and the performance condition related to the Liquidity Event was met.

The fair value of the RSUs was estimated based on a third-party valuation as of the grant date of March 4, 2021 and was derived primarily from the estimated probabilities of the Merger close on March 9, 2021 and the other exit assumptions. Once the liquidity event related performance condition was met as of March 9, 2021 due to the Merger, compensation expense for these RSUs began to be recognized on a graded vesting attribution approach over the requisite service period for each participant, which ranges from six-month to seventy (70)-month vesting periods. During the year ended December 31, 2021, we recorded approximately $40.5 million of stock-based compensation expense related to these awards, of which approximately $18.9 million was recorded in research and development expense and approximately $21.6 million was recorded in selling, general and administrative expense, on the consolidated statement of operations.

The RSUs awarded to employees and consultants of affiliated companies were accounted for as stock-based compensation in accordance with ASU 2018-07, Compensation—Stock Compensation (Topic 718), as the compensation was in exchange for continued support or services expected to be provided to the company over the vesting periods under the NantWorks shared services agreement discussed in Note 8, Related-Party Agreements. We have evaluated the associated benefit of these awards to the affiliated companies under common control and determined that the benefit is limited to the retention of their employees. We estimated such benefit at the grant date fair value of $4.0 million and recorded $0.9 million of deemed dividends for the year ended December 31, 2021 in additional paid-in capital, on the consolidated balance sheets, with a corresponding credit to stock-based compensation expense.

Warrants

In connection with the Merger, warrants issued to NantWorks, a related party, in connection with NantCell’s acquisition of Altor were assumed by the company. After applying the Exchange Ratio at the Effective Time of the Merger, a total of 1,638,000 warrants with an exercise price of $3.24 per share were outstanding as of December 31, 2021. The fair value of $18.0 million assigned to the warrants will be recognized in equity upon achievement of a performance-based vesting condition pertaining to building manufacturing capacity to support supply requirements for one of our product candidates.

11. Income Taxes

We are subject to U.S. federal income tax, as well as income tax in Italy, South Korea, California and other states. From inception through December 31, 2021, we have not been required to pay U.S. federal and state income taxes because of current and accumulated net operating losses. Our federal returns for tax years 2018 through 2020 remain open to examination, and our state returns remain subject to examination for tax years 2017 through 2020. The Italian and South Korea returns for tax years 2016 through 2020 remain open to examination. Carryforward attributes that were generated in years where the statute of limitations is closed may still be adjusted upon examination by the Internal Revenue Service (IRS) or other respective tax authorities. No income tax returns are currently under examination by taxing authorities. There are no cumulative earnings in our Italian and South Korean subsidiaries as of December 31, 2021 that would be subject to U.S. income tax or foreign withholding tax. We plan to indefinitely reinvest any future earnings of our foreign subsidiaries.

On March 9, 2021, the company completed the Merger with NantCell. The Merger is accounted for as a transaction between entities under common control, and is considered a nontaxable transaction for U.S. income tax purposes, as it is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the Code).

As of December 31, 2021, we have federal net operating losses (NOLs) of $1.3 billion, state NOLs of $1.2 billion, and foreign NOLs of $8.0 million. Of the $1.3 billion in federal NOLs, $850.3 million do not expire and will be able to be used to offset 80% of taxable income in future years. Of the $1.2 billion in state NOLs, $50.4 million do not expire and will be able to be used to offset 80% of taxable income in future years. The remaining federal NOL carryforwards expire beginning in 2022, the remaining state NOL carryforwards expire beginning in 2022, the South Korean NOL carryforwards expire beginning in 2022 and the Italian NOLs do not expire.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some or all of our deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the level of historical operating results and the uncertainty of economic conditions, we have recorded a valuation allowance of $375.1 million and $261.4 million as of December 31, 2021 and 2020, respectively. The change in the valuation allowance for the years ended December 31, 2021 and 2020 were increases of $113.7 million and $63.4 million, respectively, which were mainly driven by losses from which we cannot benefit. The portion of the valuation allowance for deferred tax assets for which subsequently recognized tax benefits will be credited directly to contributed capital is $0.2 million.

A reconciliation of the federal statutory income tax rate to our effective income tax rate is as follows:

State income taxes, net of federal tax benefit	7.0	%	7.2	%	(0.8)	%

Valuation allowance	(32.7)	%	(28.2)	%	11.7	%
Effective income tax rate	0.0	%	0.8	%	0.1	%

Pursuant to Code Sections 382 and 383, annual use of our net operating loss and research and development credit carryforwards may be limited in the event a cumulative change in ownership of more than 50% occurs within a three-year period. We have not recognized the deferred tax assets for federal and state NOLs and credits of $274.2 million from our deferred tax asset schedules as of December 31, 2021 due to Section 382/383 limitations. There is no impact to tax expense for the derecognition of net operating losses, and federal and state research and development credits due to the valuation allowance recorded against our deferred tax assets.

As of December 31, 2021, we also had federal research tax credit carryforwards of $22.6 million and state research tax credits of $8.4 million. The federal research tax credit carryforwards expire beginning in 2032 and certain state research tax credit carryforwards expire beginning in 2030. Our California research tax credits can be carried forward indefinitely.

Net operating losses and tax credits also are limited when there is a separate return limitation year (SRLY). These rules generally limit the use of the acquired or departing members’ net operating loss and tax credit carryovers to the amount of taxable income such entity contributes to consolidated taxable income. The 80% limitation also applies to SRLY NOL carryovers and tax credits. Therefore, any SRLY NOLs and tax credits will be subject to this limitation, as well as Section 382 and 383 limitations.

As of December 31, 2021 and 2020, we have $33.1 million and $19.6 million of interest, respectively, that is temporarily disallowed pursuant to IRC Section 163(j). This interest can be carried forward indefinitely and will be deductible when the company generates sufficient adjusted taxable income.

On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief and Economic Security Act (the CARES Act). The Cares Act is an emergency economic stimulus package that includes spending and tax breaks to strengthen the U.S. economy and fund a nationwide effort to curtail the effect of COVID-19. The CARES Act provides sweeping tax changes in response to the COVID-19 pandemic. Under the CARES Act, some of the more significant provisions are NOL carrybacks for five years to offset previous years’ income, or can be carried forward indefinitely to offset 100% of taxable income for the tax year beginning before 2021 and 80% of taxable income for tax years 2021 and thereafter, increasing the ability to deduct interest expense, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act. As of December 31, 2021 and 2020, we did not record any income tax (provision) benefit resulting from the CARES Act, mainly due to our history of net operating losses generated and the maintenance of a full valuation allowance against our net deferred tax assets. There was no material impact from the provisions of the Cares Act for the years ended December 31, 2021 and 2020.

On June 29, 2020, the state of California enacted Assembly Bill No. 85 (AB 85) suspending California NOL utilization and imposing a cap on the amount of business incentive tax credits companies can utilize, effective for tax years 2020, 2021 and 2022. There was no material impact from the provisions of AB 85 for the years ended December 31, 2021 and 2020. On February 9, 2022, Senate Bill No. 113 was enacted that removed the limitations on the use of NOLs and the cap on the business incentive tax credits that were suspended in accordance with AB 85 effective for tax year 2022.

A summary of changes to the amount of unrecognized tax benefits is as follows (in thousands):


	Year Ended December 31,
	2021		2020		2019
Unrecognized tax benefits, beginning of year	$	20,413	$	15,656	$	11,983
Additions based on tax positions related to the current year	536		4,763		3,680

Reductions for tax positions of prior years	(7,445)		(6)		(7)

Unrecognized tax benefits, end of year	$	13,504	$	20,413	$	15,656

Included in the balance of unrecognized tax benefits as of December 31, 2021 is $11.4 million that, if recognized, would not impact our income tax benefit or effective tax rate as long as the deferred tax asset remains subject to a full valuation allowance. We do not expect that the unrecognized tax benefits will change within 12 months of December 31, 2021. Due to the existence of the valuation allowance, future changes in our unrecognized tax benefits will not impact our effective tax rate. We have not incurred any material interest or penalties as of the current reporting date with respect to income tax matters.

Prior to the adoption of ASU 2019‑12 in the first quarter of 2020, intra-period tax allocation rules required us to allocate the provision for income taxes between continuing operations and other categories of earnings, such as other comprehensive (loss) income. In periods in which we had a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as other comprehensive (loss) income, we had to allocate the tax provision to the other categories of earnings. We then recorded a related tax benefit in continuing operations. However, with the adoption of ASU 2019‑12, we are no longer required to allocate the tax provision to the other categories of earnings and related benefits to continuing operations under these circumstances.

12. Employee Benefits

Defined Contribution Benefit Plan

In December 2015, we adopted a 401(k) retirement and savings plan (the 401(k) Plan) covering all employees. The 401(k) Plan allows employees to make pre- and post-tax contributions up to the maximum allowable amount set by the IRS. The company, at its discretion, may make certain contributions to the 401(k) Plan. We made contributions totaling $1.7 million, $1.1 million and $0.9 million to the 401(k) Plan for the years ended December 31, 2021, 2020 and 2019, respectively.

Compensated Absences

Under our vacation policy, salaried employees are provided unlimited vacation leave. Therefore, we do not record an accrual for paid leave related to these employees since we are unable to reasonably estimate the compensated absences that these employees will take.

Increase in Shares of Common Stock Authorized for Issuance

Acquisition of cGMP ISO Class 5 Manufacturing Facility

We paid approximately $40.0 million to Athenex, and the leasehold interest in the Dunkirk Facility was transferred to us. Our annual lease payment will be $2.00 per year for an initial 10-year term, with an option to renew the lease under substantially the same terms and conditions for an additional 10-year term. As part of the transaction, we assumed obligations under various third-party agreements, and committed to spend $1.52 billion on operational expenses during the initial term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. We also committed to hiring 450 employees at the Dunkirk Facility within the first five years of operations, with 300 such employees to be hired within the first 2.5 years of operations. We are eligible for certain sales-tax exemption savings during the development of the Dunkirk Facility, and certain property tax savings over the next 20 years, subject to certain terms and conditions, including performance of certain of the obligations described above.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives of ensuring that information we are required to disclose in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer (CEO) and chief financial officer (CFO), as appropriate, to allow timely decisions regarding required disclosures, and is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. There is no assurance that our disclosure controls and procedures will operate effectively under all circumstances.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our CEO and CFO, 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. Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; and (ii) provide reasonable assurance (a) that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, (b) that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (c) regarding the prevention or timely detection of the unauthorized acquisition, use or disposition of assets that could have a material effect on our financial statements.

As of December 31, 2021, our management conducted an evaluation of the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013). Based on this evaluation, our management concluded that, as of December 31, 2021, our internal control over financial reporting was effective.

The effectiveness of the company’s internal control over financial reporting has been audited by Ernst & Young LLP, our independent registered public accounting firm, as stated in its attestation report appearing on page 136 of this Annual Report under the heading “Report of Independent Public Accounting Firm on Internal Control Over Financial Reporting”, which expresses an unqualified opinion concerning the effectiveness of the company’s internal control over financial reporting as of December 31, 2021.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the fiscal quarter ended December 31, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Table of Contents

Inherent Limitations on Effectiveness of Controls

Management recognizes that a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud or error, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
