Cautionary Note Regarding Forward-Looking Statements

This report includes expectations, beliefs, projections, estimates, future plans and strategies, anticipated events or trends, and similar expressions concerning matters that are not historical facts and that are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act, and Section 21E of the Exchange Act. Forward-looking statements may appear throughout this report, including, but not limited to, Management’s Discussion and Analysis of Financial Condition and Results of Operations”. The forward-looking statements included in this report include statements regarding our future financial position and operating results, as well as our strategy, future operations, prospects, plans and objectives of management. In some cases, you can identify these forward-looking statements by the use of terminology such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “projects,” “anticipates,” or the negative version of these words or other comparable words or phrases.

These forward-looking statements are based on management’s current expectations, assumptions, hopes, beliefs, intentions, strategies, and plans regarding future events and performance and are based on currently available information as to the outcome and timing of future events and performance. We caution you that these forward-looking statements are subject to risks and uncertainties (including those described in our filings with the Securities and Exchange Commission), most of which are difficult to predict and many of which are beyond our control, incident to our operations.

These forward-looking statements are based on information available as of the date of this report. While our management believes such information forms a reasonable basis for such statements, such information may be limited or incomplete, and such statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely upon these statements.

Current expectations, forecasts and assumptions involve a number of risks and uncertainties. Accordingly, forward-looking statements in this report should not be relied upon as representing our views as of any subsequent date, and we do not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

As a result of a number of known and unknown risks and uncertainties, our actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include:

•our ability to continue as a going concern and to secure additional financing needed to meet short-term and long-term liquidity needs, which would become particularly challenging in the near future if we are unable to restructure our obligations under the senior secured promissory note (the "RP Note" and as assigned, the “K1 Note”) with Meridian Topco LLC (“Meridian”), which matured on January 31, 2024;

•our business, including our management, is required to take or is restricted from taking various actions under the terms of the K1 Note and the Forbearance Agreement, dated as of February 5, 2024, entered into by and among the Company, guarantors under the RP Note and RP Ventures (the “Forbearance Agreement”), which could adversely affect our ability to execute our operating plans or address other strategic priorities such as raising additional capital;

•our ability to execute the restructuring plan we announced in October 2023 and to realize the expected improvements to our operating results and liquidity from that plan;

•our failure to meet the continued listing requirements of the NYSE (or another national securities exchange), which could result in the delisting of our securities, or otherwise our failure to continue listing on NYSE (or another national securities exchange), could limit the value of our securities and liquidity and otherwise negatively impact or business;

•our ability to compete in an increasingly competitive environment, including our ability to effectively evolve our business;

•our ability to retain, recruit and integrate qualified personnel, including officers, directors and other key personnel (including those with public company experience);

•our ability to retain existing customers and their business and attract additional customers and their business;

•any breach of our security measures, or those of our service providers or customers, or if unauthorized parties otherwise obtain access to our or our customers’ data or software;

•intellectual property, information technology and privacy requirements that may subject us to unanticipated liabilities;

5

•our ability to realize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, and our ability to manage our operations, including potential growth and expansion of our business operations and building out controls, effectively;

•our ability to effectively operate as a public company;

•any regulatory actions or litigation (including the claims discussed elsewhere in this report) relating to, among other things, the Business Combination; and

•the other risks and uncertainties set forth in this report in the section titled “Risk Factors”.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Description of Business

Description of Business

MariaDB plc (“MariaDB” or the “Company”) provides one of the most popular general purpose relational databases. The Company’s operations consist of programming, development and sales of software programs, applications and tools related to enterprise database software. In addition, the Company provides user support, consultation and training for the software, applications, tools, and systems. The Company is active in development of both open source and closed source software.

The Company is headquartered in Redwood City, California and Dublin, Ireland, with operations in other locations including Espoo, Finland, and Sofia, Bulgaria.

Liquidity and Going Concern

As of March 31, 2024, the Company had an accumulated deficit of $261.7 million and $1.8 million in cash and cash equivalents. The Company has determined our current cash and cash equivalents will not be sufficient to fund operations (including the repayment of the RP Note and related interest that was due in January 2024 (refer to Note 8 Debt for additional discussion)), for at least 12 months from the date these financial statements were issued (May 15, 2024), raising substantial doubt about our ability to continue as a going concern.

The Company is currently in the process of being acquired and is seeking financing to avoid any potential shortfall of cash and cash equivalents to fund operations, for at least 12 months from the date the financial statements were issued.

The Company’s need for additional capital may depend on many factors, including subscription revenue growth rate, subscription renewals, billing timing and frequency, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the need for necessary technology and operating infrastructure to support the business, the introduction of new and enhanced database features and functionality and the continued market adoption of database solutions. The Company is currently seeking additional debt financings to meet projected working capital and operational requirements. However, such additional financings are subject to market conditions, and are not within the Company’s control, and therefore cannot be deemed probable as adequate capital may not be available to the Company when needed or on acceptable terms. There is no assurance that the Company will be successful in raising additional funds. As a result, the Company has concluded that potentially raising funds does not alleviate substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern and do not include adjustments that might result from the outcome of this uncertainty.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying Unaudited Condensed Consolidated Financial Statements, including the accounts of MariaDB and its wholly-owned subsidiaries have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). All intercompany balances and transactions among have been eliminated in consolidation.

Revenue Recognition

Deferred revenues consist of customer contracts billed or cash received that will be recognized in the future under subscriptions existing at the balance sheet date. The current portion of deferred revenues represents amounts that are expected to be recognized within one year of the balance sheet date. As of March 31, 2024 and September 30, 2023, the balance of deferred revenue was $44.0 million and $46.6 million, respectively, which includes $11.9 million and $12.4 million of refundable customer deposits, respectively.

Revenue recognized during the three months ended March 31, 2024 and 2023 that was included in the deferred revenue beginning balance of each year was $7.1 million and $6.7 million, respectively. Revenue recognized during the six months

12

ended March 31, 2024 and 2023 that was included in the deferred revenue beginning balance of each year was $18.4 million and $16.7 million, respectively.

Incremental direct costs of obtaining a contract are included in prepaid and other current assets and other noncurrent assets, respectively, in the Unaudited Condensed Consolidated Balance Sheets. The current and noncurrent deferred commissions had a balance of $5.3 million and $5.6 million as of March 31, 2024 and September 30, 2023, respectively.

Concentration of Credit Risk

As of March 31, 2024, two customers accounted for 39.5% of the total balance of accounts receivable, net. As of September 30, 2023, one customer accounted for 10.5% of the total balance of accounts receivable, net.

Note 3. Revenue

Disaggregation of Revenue

The Company believes that the nature, amount, timing and uncertainty of its revenue and cash flows and how they are affected by economic factors is most appropriately depicted through the Company’s primary geographical markets. The

13

Company’s primary geographical markets are North and South America (“Americas”); Europe, Middle East and Africa (“EMEA”); and Asia Pacific (“APAC”).

The following table summarizes the disaggregation of revenue by geography for the three and six months ended March 31, 2024 and 2023 respectively.

	Three Months Ended March 31,				Six Months Ended March 31,
	2024		2023		2024		2023

Total revenue	$	13,585	$	13,474	$	27,197	$	26,279

Revenue attributable to the United States comprised 39.6% and 42.9% of the total consolidated revenue for the three months ended March 31, 2024 and 2023, respectively. Revenue attributable to the United States comprised 41.1% and 42.6% of the total revenue for the six months ended March 31, 2024 and 2023, respectively. No other country outside of the United States comprised more than 10% of revenue for the three and six months ended March 31, 2024 and 2023. Revenue by location is determined by the billing address of the customer.

Revenue from professional services recognized at a point in time amounted to $0.3 million and $0.1 million and revenue from professional services recognized over time amounted to $1.1 million and $1.4 million for the three months ended March 31, 2024 and 2023, respectively. Revenue from professional services recognized at a point in time amounted to $0.4 million and $0.3 million and revenue from professional services recognized over time amounted to $2.3 million and $2.7 million for the six months ended March 31, 2024 and 2023, respectively.

Remaining Performance Obligations

Remaining performance obligations represent the aggregate amount of the transaction price in contracts allocated to performance obligations not delivered, or partially undelivered as of the end of the reporting period. Remaining performance obligations estimates are subject to change and are affected by several factors, including terminations, changes in the scope of contracts, adjustments for revenue that have not materialized and adjustments for currency. As of March 31, 2024, approximately $57.5 million of revenue is expected to be recognized from remaining performance obligations. The Company expects to recognize revenue approximately 50.8% of these remaining performance obligations over the next 12 months. The Company’s subscription contracts are recognized ratably over the contract term. Accordingly, the majority of the Company’s noncurrent remaining performance obligation is expected to be recognized in the next 13 to 36 months with the remainder recognized thereafter.

Fair values of the Public and Private Warrants were determined using publicly traded warrant prices at the end of each period. Fair values of the remaining warrants and option rights were determined using the Black-Scholes option-pricing model with the following input assumptions:

	Six Months Ended March 31,
	2024	2023
Expected volatility range (weighted average)	44.07%	47.79%
Dividend yield	0.00%	0.00%
Risk-free interest rates range (weighted average)	4.89%	3.80%
Expected term range (weighted average)	2.63 years	3.13 years

Assumptions were weighted by the relative fair value of the instruments. An increase in the expected volatility, risk-free interest rates, and expected term would result in an increase to the estimated value of the warrants while an increase in the dividend yield would result in a decrease to the estimated value of the warrants.

Note 7. Commitments and Contingencies

The Company is subject to claims, legal proceedings, governmental actions, and assessments from time to time in the ordinary course of business, including without limitation, actions with respect to intellectual property, employment, regulatory, product liability and contractual matters. In connection with these matters, the Company regularly assesses the probability and amount (or range) of possible issues based on the developments in these matters and more generally the significance of these matters to the Company. A liability is recorded in the accompanying Unaudited Condensed Consolidated Financial Statements if it is determined that it is probable that a loss has been incurred and the amount (or range) of the loss can be reasonably estimated. The Company’s management currently does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows; provided, however, if any such matters individually or in the aggregate are decided adversely to the Company, then such matters may have a material adverse effect.

In January 2023, MariaDB received a demand letter on behalf of Houlihan Lokey Capital, Inc., a financial services company that advised Legacy MariaDB in connection with a financing transaction which closed in January 2022, for which that financial services company had provided advisory services and for which MariaDB paid its fee. The demand is for an additional fee based on a de-SPAC transaction which closed in December 2022. On July 11, 2023, Houlihan Lokey Capital, Inc. filed a lawsuit against the Company in the Supreme Court of the State of New York asserting claims against the Company for breach of contract and unjust enrichment and demand judgment against the Company in an unspecified amount exceeding $6.3 million, plus interest. The Company has answered the complaint and the matter is nearing the end of the fact discovery phase. At the current stage of the litigation, it is not possible to estimate the amount or range of possible loss that might result from an adverse judgment or a settlement of this matter. As of March 31, 2024, the Company accrued $1.0 million in other accrued expenses related to a settlement offer the Company made in this matter.

In February 2023, a second financial services company sent MariaDB an additional invoice for approximately $1.3 million under the same circumstances as described in the matter above. MariaDB denies that it owes any additional fees, and no

legal proceedings have been filed in connection with this fee claim. MariaDB intends to defend any legal proceedings that may be filed.

Loan facility agreement with RP Ventures LLC (Purchased by Meridian Topco LLC)

On October 10, 2023, the Company issued a senior secured promissory note, dated as of October 10, 2023 and amended on January 10, 2024, to RP Ventures in the principal amount of $26.5 million. RP Ventures acted as the initial Agent as defined in the RP Note (in such capacity, the “Agent”). On April 24, 2024, Meridian Topco LLC (“Meridian”), an affiliate of K1 Investment Management, LLC, a Delaware limited liability company (“K1”), purchased from RP Ventures, at a premium, all right, title and interest in, to and under the RP Note (the “RP Note Acquisition”). Further, Meridian Topco LLC became the Successor Agent (as defined in the note).

The proceeds of the RP Note were used by the Company to repay all amounts outstanding under the term loan (the "Term Loan") from European Investment Bank ("EIB"), to pay RP Ventures a nonrefundable funding fee of $132,500, to pay or reimburse RP Ventures and Runa Capital Fund II, L.P. (“Runa”) for its out-of-pocket expenses related to the RP Note transaction, and to pay for working capital purposes as approved by the Company’s board of directors.

Interest on the RP Note accrued on the principal amount at the rate of ten percent (10%) per annum and was payable commencing on January 1, 2024 and quarterly thereafter in arrears on the first business day of each calendar quarter and on the maturity date, whichever was earlier.

While the RP Note remains outstanding, the note restricts the Company from pursuing or accepting any offer with respect to any recapitalization, reorganization, merger, business combination, purchase, sale, loan, notes issuance, issuance of other indebtedness or other financing or similar transaction, or to any acquisition by any person or group, which would result in any person or group becoming the beneficial owner of 2% or more of any class of equity interests or voting power or consolidated net income, revenue or assets, of the Company, in each case other than with the note holder.

The RP Note contains certain customary representations and warranties and covenants of the Company. In addition, the Company has agreed to, among other things, provide to the note holder certain financial information, maintain minimum aggregate liquidity in an amount to be agreed upon after the Closing Date by the Board and the Agent or Successor Agent, and make disbursements and collect receivables based on budget amounts.

The RP Note limits the ability of the Company to, among other things, (i) incur indebtedness, (ii) create certain liens, (iii) declare or distribute dividends or make certain other restricted payments, (iv) be party to a merger, consolidation, division or other fundamental change, (v) transfer, sell or lease Company assets, (vi) make certain modifications to the Company’s organizational documents or indebtedness, (vii) engage in certain transactions with affiliates, (viii) change the Company’s business, accounting or reporting practices, name or jurisdiction or organization, (ix) establish new bank accounts, and (x) establish or acquire any subsidiary. In addition, without the Agent or Successor Agent’s prior consent, the Company will be restricted in, among other things, taking part in transactions outside of the ordinary course of its existing business, making certain payments, or issuing equity interests.

The RP Note provides for customary events of default, including for, among other things, payment defaults, breach of representations and certain covenants, cross defaults, insolvency, dissolution and bankruptcy, certain judgments against the Company, and material adverse changes. In the case of an event of default, the note holder may demand immediate repayment by the Company of all or part of the amounts outstanding, if any, under the RP Note.

19

In connection with issuance of the RP Note, the Company and MariaDB USA. Inc. and certain other of the Company’s subsidiaries (the “Guarantors”) entered into a Guarantee and Collateral Agreement, pursuant to which the Company and each Guarantor pledged substantially all of their respective assets as collateral for the RP Note and each Guarantor guaranteed to the note holder the payment of all obligations arising from the RP Note.

The RP Note was initially due on the earlier of (i) January 10, 2024, (ii) the occurrence of a "change of control" (as that term is defined in the RP Note), (iii) the occurrence of any breach of any of the documentation relating to the Company’s Term Loan or any demand for repayment of the Term Loan, and (iv) the date on which the RP Note is otherwise declared due and payable pursuant to its terms. On January 10, 2024, MariaDB entered into an amendment (the “First Amendment”) of the RP Note. The First Amendment, among and between the Company, RP Ventures, and other note parties to the RP Note, extended (i) the maturity date of the RP Note from January 10, 2024 to January 31, 2024, providing time for the Company to continue to work with parties related to the note holder on a recapitalization structure and (ii) the exclusivity period under the RP Note from January 10, 2024 to January 31, 2024. The Company paid RP Ventures a nonrefundable funding fee of $75,000 relating to the First Amendment.

On January 31, 2024, the RP Note matured. The Company did not pay the outstanding principal, interest, and other applicable fees or charges due and payable on the RP Note. In addition, the Company and the Guarantors under the RP Note failed to comply with certain other obligations under the RP Note. This nonpayment and compliance failure gave rise to events of default under the RP Note. On February 5, 2024, to allow for further negotiations with respect to a transaction to restructure all or any material part of the obligations under the RP Note and any amendment or extension of the RP Note (the “RPV Transaction”), the Company and the Guarantors entered into the Forbearance Agreement with RP Ventures. Pursuant to the Forbearance Agreement, RP Ventures agreed not to exercise its rights and remedies in relation to the defaults under the RP Note identified in the Forbearance Agreement until February 21, 2024, subject to certain limitations and conditions. In addition, the Company agreed to pay RP Ventures a forbearance fee of $100,000 and to reimburse all reasonable and documented fees and out-of-pocket expenses of RP Ventures and any of its directors, officers, employees or agents, including its counsel, consultant and any other advisors, in connection with the Forbearance Agreement, the RP Note, the Guarantee and Collateral Agreement and other related RP Note documents. Under the terms of the Forbearance Agreement, interest on amounts due under the RP Note accrues at the default rate of 2% above the otherwise-applicable non-default interest rate of 10%.

During the three and six month periods ended March 31, 2024, the Company paid RP Ventures approximately $2.0 million which included approximately $0.9 million related to principal and approximately $1.1 million of interest.

During the three months ended March 31, 2024, the Company incurred cash interest expense of $0.8 million and non-cash interest expense (amortization of debt issuance cost) of $0.6 million on the RP Note. During the six months ended March 31, 2024, the Company incurred cash interest expense of $1.4 million and non-cash interest expense (amortization of debt issuance cost) of $3.1 million on the RP Note.

The Company was not in compliance with the covenants of the RP Note as of March 31, 2024.

Loan facility agreement with European Investment Bank

The Term Loan was disbursed on October 11, 2019 and had a maturity date of October 11, 2023, at which time it was fully repaid. The Term Loan accrued interest between 6.0%-9.5% per annum, depending on MariaDB’s monthly recurring revenue. The effective interest rate on the Term Loan for the period the Term Loan was outstanding during the quarter ended December 31, 2023 and for the full quarter ended December 31, 2022 was 6.0%. As of September 30, 2023, the Company was in compliance with its debt covenants for the Term Loan.

The schedule of required principal payments remaining on debt outstanding as of March 31, 2024 is as follows:

Note 9. Income Taxes

The Company maintains a full valuation allowance against its net deferred tax assets as of March 31, 2024 and September 30, 2023, based on the current assessment that it is not more likely than not these future benefits will be realized before expiration. No material income tax expense or benefit has been recorded given the valuation allowance position and projected taxable losses in the jurisdictions where the Company files income tax returns. The Company has not experienced any significant increases or decreases to its unrecognized tax benefits since September 30, 2023 and does not expect any within the next 12 months.

Note 10. Related-Party Transactions

Sales to and purchases from related parties are made on terms equivalent to those that prevail in arm’s length transactions. The Company had related party sales of $0.4 million and $0.2 million to a related party shareholder for the six months ended March 31, 2024 and 2023, respectively. The Company had no accounts receivable from related parties as of both periods ended March 31, 2024 and September 30, 2023.

RP Note, First Amendment, and Forbearance Agreement

On October 10, 2023, the Company issued the RP Note to RP Ventures, which had an initial maturity date of January 10, 24. On January 10, 2024, the RP Note maturity date was extended to January 31, 2024 pursuant to the First Amendment. On January 31, 2024, the RP Note matured. The Company did not pay the outstanding principal, interest, and other applicable fees or charges due and payable on the RP Note. In addition, the Company and the Guarantors under the RP Note failed to comply with certain other obligations under the RP Note. This nonpayment and compliance failure gave rise to events of default under the RP Note. On February 5, 2024, RP Ventures agreed not to exercise its rights and remedies in relation to the defaults under the RP Note identified in the Forbearance Agreement until February 21, 2024. See Note 8 - Debt for additional information and terms of the RP Note, First Amendment, and the Forbearance Agreement.

Pursuant to Board appointment rights granted under the RP Note, RP Ventures appointed two directors, Michael Fanfant and Yakov Zubarev, to the Board on October 10, 2023. Mr. Fanfant and Mr. Zubarev have relationships with RP Ventures or certain Company shareholders and their affiliates. Mr. Fanfant is a shareholder of Runa Capital II (GP), the general partner of Runa Capital Fund II, L.P., and Runa Capital Opportunity I (GP), the general partner of Runa Capital Opportunity Fund I, L.P. and the managing shareholder of Runa Ventures I Limited, which collectively beneficially own more than 5% of the Company’s outstanding ordinary shares.

Note 13. Restructuring and other charges

On October 12, 2023, the Company announced its plan to better align its workforce with the needs of its business and to reduce the Company’s operating costs. The plan included a reduction of the Company’s workforce by approximately 84 individuals. During the three months ended March 31, 2024, the Company recorded an additional restructuring charge of approximately $0.5 million related to a reduction of the workforce of approximately 12 individuals. The total restructuring charge for the six months ended March 31, 2024 was approximately $3.2 million, which was related primarily to headcount. The Company believes it restructuring efforts will be substantially completed by June 30, 2024.

Note 14. Divestitures

SkySQL

On November 17, 2023, the Company entered into an Asset Purchase Agreement (“APA”) by and among MariaDB plc, MariaDB USA, Inc. and SkyDB, Inc. (“Sky”), completing the divestiture of the SkySQL business. Under the terms of the APA, Sky purchased all of the intellectual property, technology, operational contracts and other assets related to the SkySQL business in exchange for: (a) a to-be issued minority equity interest of ten (10%) percent of the common equity of Sky upon a third-party financing of Sky; and (b) the release and extinguishment of severance obligations for certain former Company employees who chose to become employees of Sky. All parties to the APA are subject to non-competition and non-solicitation covenants for twelve months following the effective date of the APA. Under the revenue sharing and customer transition provisions of the APA, the Company is entitled to 30% of the net revenues of any assigned customer agreement.

The Company will have no seat on the Board of Directors or any significant influence over Sky's' financial or operational decisions. The minority interest in Sky is considered immaterial to the financial statements.

The net book value of the assets related to the Sky business were all previously written off as a result of the annual goodwill impairment analysis as of September 30, 2023. In the three month period ended December 31, 2023, the Company reported a gain on the divestiture of the business of approximately $0.9 million related to the release and extinguishment of severance obligations for certain former Company employees who chose to become employees of Sky.

The divestiture did not represent a strategic shift; therefore the operating results of SkySQL did not qualify for reporting as discontinued operations.

CubeWerx

On December 30, 2023, the Company agreed to sell, assign and transfer all of the purchased contracts, intellectual property and servers/hardware of its Canadian subsidiary for a nominal amount of consideration.

As part of the divestiture, the Company is legally obligated to provide the buyer with a loan of approximately $0.6 million. The loan is interest bearing and matures in July 2029.

The Company is also required to subscribe to 10% ownership of the buyer’s newly formed company. The investment will be considered immaterial to the Company’s financial statements. The Company will have no seat on the Board of Directors or any significant influence over its financial or operational decisions.

23

The assets of the divested business were all previously written off as a result of the annual goodwill impairment analysis as of September 30, 2023. No gain or loss was reported on the sale of the company. The divestiture did not represent a strategic shift; therefore the operating results of the divested company did not qualify as discontinued operations.

Overview

MariaDB is a database company whose products are used by companies big and small, reaching over a billion users through Linux distributions, downloaded over a billion times, and used across all types of use cases and industries. Built for all clouds (public, private and hybrid), our open source relational database delivers the flexibility and elasticity businesses need in today’s world with the reliability and dependability necessary to power the most mission critical applications. Rooted in open source, MariaDB is open and transparent, working hand-in-hand with customers to solve their data storage and access challenges at a fraction of the cost of legacy databases.

We generate revenue primarily from two sources:

•Subscriptions: subscriptions to MariaDB Enterprise solutions are sold in conjunction with post-contract support, or PCS. Our subscription agreements for Maria DB Enterprise solutions typically have terms of one to three years. Our subscription agreements generally provide for future updates, upgrades, enhancements, and technical product support.

•Services: professional services consisting primarily of consulting, training, remote database administration, and enterprise architect services.

MariaDB database solutions are capable of supporting an organization’s growth, scaling to millions of users and millions of transactions per second with ease. The commercial components of our enterprise database solutions are the MariaDB Enterprise Server, MariaDB MaxScale, and MariaDB Enterprise ColumnStore. These components, which can be installed by the customer on their specific hardware in a private data center or in a public cloud, are provided under a licensing framework that aims to protect our intellectual property and drive our software subscription model while still allowing for contributions to MariaDB open source code, which fosters a healthy, growing MariaDB ecosystem.

To support our database solutions and increase customer satisfaction and retention, we provide professional services to aid our customers in making their applications on the MariaDB platform successful. Our services revenue accounted for 10.2% and 10.8%, respectively, of our total revenue during the three months ended March 31, 2024 and 2023 and 10.0% and 11.3%, respectively, of our total revenue during the six months ended March 31, 2024 and 2023. We continue to invest in our professional service offerings as part of our customer retention and expansion strategy.

Our database solutions are used globally by organizations of all sizes across a broad range of industries. We currently offer our products in the (1) Americas, (2) Europe, the Middle East, and Africa (“EMEA”), and (3) Asia-Pacific (“APAC”). Our

24

revenue from those regions constituted 43%, 38%, and 19%, respectively, of our revenue for the three months ended March 31, 2024, and 48%, 34%, and 18%, respectively, of our revenue for the three months ended March 31, 2023. Revenue from those regions constituted 44%, 36%, and 20%, respectively, of our revenue for the six months ended March 31, 2024, and 48%, 35%, and 17%, respectively, of our revenue for the six months ended March 31, 2023. We believe international expansion represents a meaningful opportunity to generate further demand for our solutions in international markets. We plan to invest in our operations internationally to reach new customers by expanding in targeted key geographies where we believe there are opportunities for significant return on investment.

Key Factors Affecting Our Performance

Acquiring New Customers. We believe that there is significant opportunity to expand our customer base by continuing to make substantial investments in sales, marketing, and brand awareness. Our ability to attract new customers will depend on several factors, including our success in recruiting, training, retaining, and scaling our sales and marketing organization, as well as our ability to capitalize on the competitive dynamics of our target markets. While our database solutions are built for organizations of all sizes and industries, we intend to expand our direct sales force with a primary focus on increasing sales to large enterprises. Secondarily, sales force expansion will be necessary to cover a wider array of global markets that are currently underserved.

Expansion Within Our Existing Customer Base. We believe that there is also a significant opportunity to drive additional sales to existing customers, and we expect to invest in sales and marketing and customer success personnel and activities to achieve additional revenue growth from existing customers. Our customers may potentially expand their subscriptions to our database solutions as they migrate additional existing applications or build new applications, either within the same department or in other lines of business or geographies. Further, as customers modernize their information technology infrastructure and move to the cloud, they may migrate applications from legacy databases. Our goal is to increase the number of customers that standardize on our database within their organization.

Key Business Metrics

We monitor the key business metrics set forth below to help us evaluate our business and growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts, and assess operational efficiencies. The definition and calculation of the key business metrics discussed below may differ from other similarly titled metrics used by other companies, competitors, industry experts, securities analysts, and investors.

As of March 31, 2024 and 2023, our key business metrics were as follows:

	As of March 31,
($ in thousands)	2024	2023(1)
Total Annual Recurring Revenue	$53,012	$47,395
Total Net Revenue Retention Rate	104%	104%
Customers	690	655

(1) Metrics presented for the period ended March 31, 2023 have been recalculated to reflect the revised metric definition. On October 12, 2023, the Company announced its restructuring plan to focus its attention on its core MariaDB Enterprise Server database product and better align its workforce with the needs of its business. Products not related to the core MariaDB Enterprise Server business, including SkySQL and Xpand, are no longer sold and the Company has implemented a plan to help existing customers migrate off these products. As a result of the restructuring plan, we changed the definition of ARR to exclude revenue from pay-as-you-go customers related to SkySQL and one-year and multi-year contracts relating to SkySQL and Xpand products, to only include revenue from contracts which have a contract start date on or before the ARR measurement date, and to only include revenue for up to 30 days after the subscription end date for a contract for customers who are actively negotiating renewal. As a result of the change in the definition of ARR, the net revenue retention rate as of March 31, 2023 presented above has also been recalculated using ARR under the Company’s revised methodology. Customers of our SkySQL and Xpand subscription products have also been removed from our number of customers as of March 31, 2023.

Annual Recurring Revenue

We view ARR as an important indicator of our financial performance and operating results given the renewable nature of our business. ARR does not have a standardized meaning and is therefore unlikely to be comparable to similarly titled

25

metrics presented by other companies. We define ARR as the annualized revenue for our subscription customers, excluding revenue from nonrecurring contract services (e.g., time and material consulting services). For our annual subscription customers, we calculate ARR as the annualized value of their subscription contracts as of the measurement date, assuming any contract that expires during the next 12 months is renewed on its existing terms (including contracts for which we are negotiating a renewal). In the event that we are still negotiating a renewal with a customer after the expiration of their subscription, we continue to include that revenue in ARR for a maximum period of 30 days after the subscription end date. Our calculation of ARR is not adjusted for the impact of any known or projected events that may cause any such contract not to be renewed on its existing terms. Consequently, our ARR may fluctuate within each quarter and from quarter to quarter. This metric should be viewed independently of U.S. GAAP revenue and does not represent U.S. GAAP revenue on an annualized basis, as it is an operating metric that can be impacted by contract start and end dates and renewal rates. ARR is not intended to be a replacement for or forecast of revenue.

Net Revenue Retention Rate

We believe that net revenue retention rate is an important measure of the health of our business and our future growth prospects as it measures the growth in the use of our database by our existing subscription customers.

We calculate our dollar-based net retention rate as of a period end by starting with the ARR from the cohort of all subscription customers as of 12 months prior to such period end, or prior period value. We then calculate the ARR from this same customer cohort as of the current period end, or current period value, which includes any growth in the value of subscriptions and reflects the growth or contraction in customer attrition over the prior 12 months. We then divide the current period value by the prior period value to arrive at our dollar-based net retention rate. The dollar-based net retention rate includes the effect of our subscriptions that expand, renew, contract, or terminate, but excludes ARR from new customers in the current period. Our dollar-based net retention rate is subject to adjustments for acquisitions, consolidations, spin-offs, and other market activity.

Customers

We believe the number of customers is an important indicator of the growth in our business and future revenue trends. We calculate our total number of customers at the end of each period, and we include in this calculation each customer account that has an active subscription contract with us or with which we are negotiating a renewal contract at the end of a given period. Each party with which we enter into a subscription contract is considered a unique customer and, in some cases, a single organization may be counted as more than one customer (i.e., when two or more business units of an enterprise customer each enter into subscription contracts). We exclude pay-as-you-go customers from our calculation. Our customer count is subject to adjustments for acquisitions, consolidations, spin-offs, and other market activity.

Subscription revenue

Subscription revenue increased by $0.2 million, or 1.5%, and $1.2 million, or 5.0%, from the three and six months ended March 31, 2023 to the three and six months ended March 31, 2024, respectively. The increase in subscription revenues for the three and six months ended March 31, 2024 was primarily caused by volume-driven increases from new business, which includes new customers and additional subscriptions from existing customers. Our customer base grew from 655 customers as of March 31, 2023 to 690 customers as of March 31, 2024.

Services revenue

Services revenue decreased by $0.1 million, or 4.8%, and $0.3 million, or 8.6%, from the three and six months ended March 31, 2023 to the three and six months ended March 31, 2024, respectively, primarily due to a decline in delivery of enterprise architect services and remote database administration services.

Cost of subscription revenue

Cost of subscription revenue increased by $0.1 million, or 5.1%, and nominally from the three and six months ended March 31, 2023 to the three and six months ended March 31, 2024, respectively. The increase in cost of subscription revenues for the three and six months ended March 31, 2024 was primarily caused by an increase in costs related to third-party tools and third-party hosting infrastructure costs, partially offset by a decrease in personnel-related costs as a result of headcount reduction related to restructuring activities during Q1 and Q2 2024.

Cost of services revenue

Cost of services revenue decreased by $0.6 million, or 33.1%, and $1.0 million, or 29.8%, from the three and six months ended March 31, 2023 to the three and six months ended March 31, 2024, respectively. The decrease in cost of services revenues for the three and six months ended March 31, 2024 was primarily due to a decrease in personnel-related costs as a result of headcount reduction related to restructuring activities during Q1 and Q2, 2024 and a decrease in third-party hosting infrastructure costs.

Gross margin

Our overall gross margin increased 3.7% to 79.8% and 4.5% to 79.4% during the three and six months ended March 31, 2024 compared to the same periods in fiscal year 2023, primarily due to growth in subscription revenue and personnel-related cost savings realized pursuant to our restructuring plan announced in Q1 and Q2, 2024

Sales and marketing expense decreased by $5.5 million, or 38.7%, from $14.2 million for the six months ended March 31, 2023 to $8.7 million for the six months ended March 31, 2024. The decrease was primarily attributable to a $2.9 million decrease in personnel-related expenses as a result of headcount reduction related to restructuring activities, a $1.9 million decrease in marketing expenses, and a $0.7 million decrease in other expenses, such as travel-related costs, professional fees, and technology-related costs.

General and administrative

General and administrative expense decreased by $3.1 million, or 45.8%, from $6.7 million for the three months ended March 31, 2023 to $3.6 million for the three months ended March 31, 2024. The decrease was primarily attributable to a $1.0 million decrease in legal expenses, a $0.8 million decrease in professional service fees, a $0.6 million decrease in

29

personnel-related expenses, a $0.4 decrease in insurance expense, and a $0.3 million decrease in other expenses, such as bad debt expense.

General and administrative expense decreased by $3.7 million, or 30.1%, from $12.2 million for the six months ended March 31, 2023 to $8.5 million for the six months ended March 31, 2024.

Restructuring and other charges

On October 12, 2023, the Company announced its plan to better align its workforce with the needs of its business and to reduce the Company’s operating costs. The plan included a reduction of the Company’s workforce by approximately 84 individuals. During the three months ended March 31, 2024, the Company recorded an additional restructuring charge of approximately $0.5 million related to a reduction of the workforce by approximately 12 individuals. The total restructuring charge for the six month ended March 31, 2024 was approximately $3.2 million, which was related primarily to headcount. The Company believes it restructuring efforts will be substantially completed by June 30, 2024.

Gain (loss) on divestitures

During the three and six months ended March 31, 2024, the Company recorded a loss on divestiture of approximately $0.1 million and a gain on divestiture of approximately $0.8 million, respectively, primarily related to the Company's divestiture of its SkySQL and geospatial businesses. For additional information, Refer to Note 14 Divestitures to our Unaudited Condensed Consolidated Financial Statements.

Interest expense increased by $1.1 million, or 385.5%, and $4.0 million, or 771.2%, from the three and six months ended March 31, 2023 to the three and six months ended March 31, 2024, respectively. The increase in interest expense for the three and six months ended March 31, 2024 was primarily due to the increase in interest expense and amortization of debt issuance costs related to the issuance of a senior secured promissory note to RP Ventures LLC (“RP Ventures”) in the principal amount of $26.5 million during the quarter ending December 31, 2023. For additional information, Refer to footnote 8 Debt, to our Unaudited Condensed Consolidated Financial Statements.

Change in fair value of warrant liabilities

	For the Three Months Ended March 31,				Change			For the Six Months Ended March 31,				Change

Change in fair value of warrant liabilities	$	(809)	$	2,297	$	(3,106)	NM	$	(170)	$	4,028	$	(4,198)	NM

Our warrant liabilities are remeasured at the end of each quarter to reflect changes in the fair value of warrant liabilities.

The change in fair value of warrant liabilities reflected a $0.8 million loss for the three months ended March 31, 2024, compared to $2.3 million of gain for the three months ended March 31, 2023. During the quarter ended March 31, 2024, the Company recorded a $0.8 million loss related to the increase in fair value associated with the Public and Private Warrants primarily as a result of the increase in the Company’s stock price from December 31, 2023 to March 31, 2024.

30

The change in fair value of warrant liabilities reflected a $0.2 million loss for the six months ended March 31, 2024, compared to $4.0 million of gain for the six months ended March 31, 2023. During the six months ended March 31, 2024, the Company recorded a $0.2 million loss related to the increase in fair value associated with the Public and Private Warrants primarily as a result of the increase in the trading price of the Company’s Public Warrants from September 30, 2023 to March 31, 2024.

For additional information, Refer to Note 4 Warrants, to our Unaudited Condensed Consolidated Financial Statements.

Other income (expense), net

Other income (expense), net	$	379	$	(779)	$	1,158	NM	$	(529)	$	(2,608)	$	2,079	NM

Other income (expense), net increased by $1.2 million and $2.1 million from the three and six months ended March 31, 2023 to the three and six months ended March 31, 2024, respectively, primarily due to currency exchange losses related to transactions denominated in various foreign currencies.

Income taxes

The effective tax rate realized for each period was significantly below the statutory rate of 21%, as we incurred significant operating losses during each reporting period and did not recognize an income tax benefit associated with these losses because a full valuation allowance is maintained against our net deferred income tax assets in our primary taxable jurisdiction. Amounts reflected in income tax (expense) benefit generally represent various foreign income taxes. Based on the weight of negative evidence and our projections of future taxable income, we expect to maintain our valuation allowance for the foreseeable future.

Non-GAAP Financial Measures

To supplement our financial results which are prepared and presented in accordance with U.S. GAAP, we provide investors with non-GAAP financial measures including Adjusted EBITDA and Adjusted EBITDA Margin, as defined below. These measures are presented for supplemental informational purposes only, have limitations as analytical tools and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate similarly titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of these measures as tools for comparison. Because of these limitations, when evaluating our performance, you should consider each of these non-GAAP financial measures alongside other financial performance measures, including the most directly comparable financial measure calculated in accordance with GAAP and our other GAAP results. A reconciliation of each of our non-GAAP financial measures to the most directly comparable financial measure calculated in accordance with GAAP is set forth below.

Adjusted EBITDA and Adjusted EBITDA Margin

We define Adjusted EBITDA as net loss before (1) interest expense, (2) income tax expense or benefit, (3) depreciation and amortization, (4) stock-based compensation, (5) change in fair value of warrant liabilities, (6) other income (expense), net, (7) net costs associated with discontinued products pursuant to the Company's October 2023 restructuring plan, and any other one-time non-recurring transaction amounts impacting the statement of operations during the relevant period. We believe that Adjusted EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across periods. Our management uses Adjusted EBITDA to assess our operating performance and to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that Adjusted EBITDA, when considered together with our GAAP financial results, provides meaningful supplemental information regarding our operating performance by excluding certain items that may not be indicative of our business, results of operations or outlook, such as the impact of our capital structure

31

(primarily interest charges) and asset base (primarily depreciation and amortization), items outside the control of the management team (taxes), expenses that do not relate to our core operations, and other non-cash items, including stock-based compensation, unrealized gains and losses related to foreign currency translation (included in other income (expense), net), and change in fair value of warrant liabilities. We consider Adjusted EBITDA to be an important measure because it helps illustrate underlying trends in our business and our historical operating performance on a more consistent basis.

Adjusted EBITDA Margin means Adjusted EBITDA as a percentage of revenue determined in accordance with GAAP. We calculate Adjusted EBITDA Margin by dividing Adjusted EBITDA by total GAAP revenue. We believe that Adjusted EBITDA Margin helps us to better understand MariaDB’s normalized operating performance (excluding certain non-indicative items) in the context of GAAP revenue providing management with important supplemental information in understanding business efficiency and trends.

Our calculation of Adjusted EBITDA and Adjusted EBITDA Margin may differ from how other companies, including companies in our industry, calculate these or similarly titled non-GAAP measures, which could reduce the usefulness of these measures as tools for comparison. Because of these limitations, when evaluating our performance, you should consider Adjusted EBITDA and Adjusted EBITDA Margin alongside other financial performance measures, including our net loss and other GAAP results.

Liquidity and Capital Resources

We measure liquidity in terms of our ability to fund the cash requirements of our business operations, including working capital, capital expenditure needs, contractual obligations, and other commitments, with cash flows from operations and other sources of funding. Our primary short-term requirements for liquidity and capital relate mainly to employee compensation and benefits, funds for general working capital, and the repayment of the RP Note, together with accrued interest, that became due in January 2024. (Part of the net proceeds from the financing were used to repay our outstanding term loan from EIB (the “Term Loan”). Refer to discussion below under the heading “– Debt – Loan facility agreement with European Investment Bank”.) Our primary long-term liquidity needs are related to potential acquisitions, working capital needs and the evolution of our operating cash flows.

As of March 31, 2024 , our primary sources of liquidity are from the collection of proceeds from the subscriptions of customers and cash generated from financing activities. On October 10, 2023, we entered into a senior secured debt financing transaction with RP Ventures pursuant to which we raised gross proceeds of $26.5 million. Net proceeds were $7.7 million after repayment of the Term Loan and payment of the debt issuance costs.

32

The Company incurred negative cash flow from operations of $8.6 million during the six months ended March 31, 2024. As of March 31, 2024, we had an accumulated deficit of $261.7 million.

As of March 31, 2024, we had $1.8 million in cash and cash equivalents. We are currently seeking debt financing, as we do not believe our existing cash and cash equivalents, cash provided by sales of database subscriptions, and sales of our services will be sufficient to meet our projected operating requirements (including capital expenditures and the repayment of the remaining principal and related interest of the RP Note that was due in January 2024) over the next 12 months following the date on which the Unaudited Condensed Consolidated Financial Statements were issued (May 15, 2024), and may potentially not meet our short-term and long-term working capital needs. Our future capital requirements may depend on many factors, including our subscription revenue growth rate, subscription renewals, billing timing and frequency, the timing and extent of spending to support development, expansion of sales and marketing activities, increased costs associated with being a public company, the need for necessary technology investment, the operating and controls infrastructure to support our business and compliance, the introduction of new and enhanced database features and functionality, and the continued market adoption of our database solutions. We may in the future pursue acquisitions of businesses, technologies, assets and talent, which may also require additional capital.

We have not been and are not currently profitable and cannot provide assurance that we will ever be profitable. As described in the Section “Risk Factors – Our failure to meet the continued listing requirements of the NYSE (or another national securities exchange) or otherwise our failure to continue listing on the NYSE (or another national securities exchange) could limit the value of our securities and liquidity”), NYSE is currently monitoring our liquidity condition and if we ultimately fail to satisfy the continued listing requirements of NYSE or otherwise do not continue our listing on the NYSE, the ability of current or future investors to purchase our securities in a capital raising transaction may be impaired, or the pricing and demand for a capital raising transaction may be impaired by limited liquidity for our Ordinary Shares if they are not trading on a national securities exchange.

If we are unable to raise additional capital or generate cash flows necessary to repay the RP Note or expand our operations and invest in new technologies or businesses, our business, competitive position, growth prospects, financial condition, and results of operations could be materially adversely affected. Refer to Note 1 to our unaudited Condensed Consolidated Financial Statements for additional information on this assessment.

Deferred Revenue

As of March 31, 2024, we had total deferred revenue of $44.0 million, of which $11.9 million was related to refundable customer deposits. As of March 31, 2024, the remaining performance obligations were $57.5 million, and we expect to recognize revenue on approximately 50.8% of these remaining performance obligations over the next 12 months. Our subscription contracts are recognized ratably over the contract terms; accordingly, the majority of our noncurrent remaining performance obligation is expected to be recognized in the next 13 to 36 months, with the remainder recognized thereafter.

Debt

Loan facility agreement with European Investment Bank

In October 2023, the Term Loan was repaid from the net proceeds of the RP Note.

Loan facility agreement with RP Ventures LLC (Purchased by Meridian Topco LLC)

On October 10, 2023, the Company issued a senior secured promissory note, dated as of October 10, 2023 and amended on January 10, 2024, to RP Ventures in the principal amount of $26.5 million. RP Ventures acted as the initial Agent as defined in the RP Note (in such capacity, the “Agent”). On April 24, 2024, Meridian Topco LLC (“Meridian”), an affiliate of K1 Investment Management, LLC, a Delaware limited liability company (“K1”), purchased from RP Ventures, at a premium, all right, title and interest in, to and under the RP Note (the “RP Note Acquisition”). Further, Meridian Topco LLC became the Successor Agent (as defined in the note).

The proceeds of the RP Note were used by the Company to repay all amounts outstanding under the Term Loan from EIB, to pay RP Ventures a nonrefundable funding fee of $132,500, to pay or reimburse RP Ventures and Runa Capital Fund II,

33

L.P. (“Runa”) for its out-of-pocket expenses related to the RP Note transaction, and to pay for working capital purposes as approved by the Company’s board of directors.

Interest on the RP Note accrued on the principal amount at the rate of ten percent (10%) per annum and was payable commencing on January 1, 2024 and quarterly thereafter in arrears on the first business day of each calendar quarter and on the maturity date, whichever was earlier.

While the RP Note remains outstanding, the note restricts the Company from pursuing or accepting any offer with respect to any recapitalization, reorganization, merger, business combination, purchase, sale, loan, notes issuance, issuance of other indebtedness or other financing or similar transaction, or to any acquisition by any person or group, which would result in any person or group becoming the beneficial owner of 2% or more of any class of equity interests or voting power or consolidated net income, revenue or assets, of the Company, in each case other than with the note holder.

The RP Note contains certain customary representations and warranties and covenants of the Company. In addition, the Company has agreed to, among other things, provide to the note holder certain financial information, maintain minimum aggregate liquidity in an amount to be agreed upon after the Closing Date by the Board and the Agent or Successor Agent, and make disbursements and collect receivables based on budget amounts.

The RP Note limits the ability of the Company to, among other things, (i) incur indebtedness, (ii) create certain liens, (iii) declare or distribute dividends or make certain other restricted payments, (iv) be party to a merger, consolidation, division or other fundamental change, (v) transfer, sell or lease Company assets, (vi) make certain modifications to the Company’s organizational documents or indebtedness, (vii) engage in certain transactions with affiliates, (viii) change the Company’s business, accounting or reporting practices, name or jurisdiction or organization, (ix) establish new bank accounts, and (x) establish or acquire any subsidiary. In addition, without the Agent or Successor Agent’s prior consent, the Company will be restricted in, among other things, taking part in transactions outside of the ordinary course of its existing business, making certain payments, or issuing equity interests.

The RP Note provides for customary events of default, including for, among other things, payment defaults, breach of representations and certain covenants, cross defaults, insolvency, dissolution and bankruptcy, certain judgments against the Company, and material adverse changes. In the case of an event of default, the note holder may demand immediate repayment by the Company of all or part of the amounts outstanding, if any, under the RP Note.

In connection with issuance of the RP Note, the Company and MariaDB USA. Inc. and certain other of the Company’s subsidiaries (the “Guarantors”) entered into a Guarantee and Collateral Agreement, pursuant to which the Company and each Guarantor pledged substantially all of their respective assets as collateral for the RP Note and each Guarantor guaranteed to the note holder the payment of all obligations arising from the RP Note.

The RP Note was initially due on the earlier of (i) January 10, 2024, (ii) the occurrence of a "change of control" (as that term is defined in the RP Note), (iii) the occurrence of any breach of any of the documentation relating to the Company’s Term Loan or any demand for repayment of the Term Loan, and (iv) the date on which the RP Note is otherwise declared due and payable pursuant to its terms. On January 10, 2024, MariaDB entered into an amendment (the “First Amendment”) of the RP Note. The First Amendment, among and between the Company, RP Ventures, and other note parties to the RP Note, extended (i) the maturity date of the RP Note from January 10, 2024 to January 31, 2024, providing time for the Company to continue to work with parties related to the note holder on a recapitalization structure and (ii) the exclusivity period under the RP Note from January 10, 2024 to January 31, 2024. The Company paid RP Ventures a nonrefundable funding fee of $75,000 relating to the First Amendment.

On January 31, 2024, the RP Note matured. The Company did not pay the outstanding principal, interest, and other applicable fees or charges due and payable on the RP Note. In addition, the Company and the Guarantors under the RP Note failed to comply with certain other obligations under the RP Note. This nonpayment and compliance failure gave rise to events of default under the RP Note. On February 5, 2024, to allow for further negotiations with respect to a transaction to restructure all or any material part of the obligations under the RP Note and any amendment or extension of the RP Note (the “RPV Transaction”), the Company and the Guarantors entered into the Forbearance Agreement with RP Ventures. Pursuant to the Forbearance Agreement, RP Ventures agreed not to exercise its rights and remedies in relation to the defaults under the RP Note identified in the Forbearance Agreement until February 21, 2024, subject to certain limitations and conditions. In addition, the Company agreed to pay RP Ventures a forbearance fee of $100,000 and to reimburse all reasonable and documented fees and out-of-pocket expenses of RP Ventures and any of its directors, officers, employees or agents, including its counsel, consultant and any other advisors, in connection with the Forbearance Agreement, the RP

34

Note, the Guarantee and Collateral Agreement and other related RP Note documents. Under the terms of the Forbearance Agreement, interest on amounts due under the RP Note accrues at the default rate of 2% above the otherwise-applicable non-default interest rate of 10%.

During the three and six month periods ended March 31, 2024, the Company paid RP Ventures approximately $2.0 million which included approximately $0.9 million related to principal and approximately $1.1 million of interest.

For additional information on the terms of the First Amendment and the Forbearance Agreement, refer to "Debt", Note 8 to our Unaudited Condensed Consolidated Financial Statements.

The Company is currently in the process of being acquired and is seeking debt financing to avoid any potential shortfall of cash and cash equivalents to fund operations, for at least 12 months from the date the financial statements were issued. However, such additional financings are subject to market conditions, and are not within the Company’s control, and therefore cannot be deemed probable as adequate capital may not be available to the Company when needed or on acceptable terms. There is no assurance that the Company will be successful in raising additional funds.

Cash Flows

The following table presents a summary of our cash flows for the six months ended March 31, 2024 and 2023:

	For the Six Months Ended March 31,
	2024		2023
Net cash provided by (used in)	( in thousands)
Operating activities	$	(8,583)	$	(29,448)
Investing activities	$	—	$	25,943
Financing activities	$	7,138	$	7,795

Operating activities

Cash used in operating activities consists mainly of our net loss adjusted for certain non-cash items, including stock-based compensation, depreciation of property and equipment, changes in fair value of warrant liabilities, changes in allowance for doubtful accounts, non- cash interest expense, including expense associated with amortization of debt issuance costs, restructuring and other charges, gain on divestitures, non-cash operating lease costs, amortization of deferred commissions, net foreign exchange differences, and changes in operating assets and liabilities during the period.

For the six months ended March 31, 2024, cash used in operating activities was $8.6 million, primarily consisting of our net loss of $12.3 million, adjusted for non-cash charges of $5.8 million and net cash outflows of $2.1 million related to changes in our operating assets and liabilities. Non-cash charges included $3.1 million of non-cash interest expense, including amortization of debt issuance costs, $1.2 million of foreign currency loss, net, $1.0 million of amortization of deferred commissions, $0.9 million of restructuring and other charges, and $0.5 million of other normal recurring non-cash charges, offset by $0.9 million related to gain on divestitures. The main driver of the changes in operating assets and liabilities was a result of decreases in deferred revenue and accounts payable and accrued expenses and an increase in other current assets, offset by a corresponding decrease in accounts receivable.

For the six months ended March 31, 2023, cash used in operating activities was $29.4 million, primarily consisting of our net loss of $24.5 million, adjusted for net cash outflows of $4.9 million related to changes in our operating assets and liabilities. The main driver of the changes in operating assets and liabilities was a result of an increase in accounts receivable and other current assets, offset by a corresponding increase in deferred revenue.

Investing activities

There was no cash provided (used by) investing activities for the six months ended March 31, 2024.

Cash provided by investing activities during the six months ended March 31, 2023 was $25.9 million, resulting primarily from the sale of remaining short-term investments.

35

Financing activities

Cash provided by financing activities for the six months ended March 31, 2024 totaled $7.1 million and primarily consisted of net proceeds received from RP Ventures of $24.0 million, partially offset by the repayment of the Term Loan of $16.0 million and repayments of the RP Note of $0.9 million.

Cash provided by financing activities for the six months ended March 31, 2023 totaled $7.8 million and consisted of proceeds received from the Business Combination of $10.5 million, proceeds received from the exercise of warrants of $2.9 million, and proceeds from the exercise of stock options of $0.4 million, offset by payment of offering costs of $5.4 million, settlement of warrant liabilities of $0.4 million relating to warrant rights redeemed, and repayment of borrowings of $0.1 million.

Critical Accounting Policies and Estimates

Our financial statements are prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses, as well as related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results and condition could differ from these estimates.

Our significant accounting policies are fully described in Note 2 of Part II, Item 8 in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023. There have been no material changes to the Company’s significant accounting policies since the fiscal year 2023 Form 10-K.

Recent Accounting Pronouncements

For more information, Refer to Note 2 to our Consolidated Financial Statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Credit, Interest Rate, and Foreign Currency Exchange Risk

Credit Risk

Generally, we have been able to collect our accounts receivable in the ordinary course of business. We do not hold any collateral to secure payment from customers. We have established policies and procedures relating to customer credit risk.

As of March 31, 2024, two customers accounted for 39.5% of the total balance of accounts receivable, net. As of September 30, 2023, one customer accounted for 10.5% of the total balance of accounts receivable, net. Based upon performing ongoing credit evaluations and our past collection experience, we believe that the receivable balance concentrated in two customers as of March 31, 2024 does not represent a significant credit risk, although we continue to actively monitor creditworthiness and economic conditions that may affect our customer's business and access to capital. Further, we are monitoring the current global economic conditions, including credit markets and other factors, as they relate to our customers in order to manage the risk of uncollectible accounts receivable.

Interest Rate Risk

As of March 31, 2024, we had cash and cash equivalents of $1.8 million. Currently, these funds are held in cash accounts. Currently, we have little exposure to market risk due to fluctuations in interest rates but may in the future depending on our cash management strategy. The rate of interest on our RP Note that was disbursed on October 10, 2023 is not tied to fluctuations in interest rates; therefore, any change in market rates is not expected to impact the current interest rate on the RP Note.

Foreign Currency Exchange Risk

We conduct business in several locations outside of the U.S. with a portion of our operating expenses denominated in the currencies of the countries in which our operations are located. These include Europe, United Kingdom, Canada, and India,

36

among others. The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. We have experienced and will continue to experience fluctuations in foreign exchange gains (losses) related to changes in foreign currency exchange rates, which may be significant. In the event our foreign currency denominated assets, liabilities, revenue, or expenses increase, our results of operations may be more greatly affected by fluctuations in the exchange rates of the currencies in which we do business. We have not engaged in the hedging of foreign currency transactions to date, although we may choose to do so in the future.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our principal executive and financial officers evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2024, and have concluded that because of the material weaknesses in our internal control over financial reporting, as discussed in Part II, Item 9A under the caption “Controls and Procedures” in our Annual Report on Form 10-K for the year ended September 30, 2023, filed with the SEC on December 29, 2023 and amended on January 29, 2024 (“2023 Annual Report”), these controls and procedures were not effective.

Disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time period specified in the SEC rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit is accumulated and communicated to management of the Company, including the principal executive and financial officers, as appropriate, to allow timely decisions regarding required disclosure. In light of the material weaknesses indicated above, we performed additional analysis and other post-closing procedures to ensure our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Accordingly, our management, including our principal executive and financial officers, have concluded that the Unaudited Condensed Consolidated Financial Statements included in this Form 10-Q present fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP.

Limitations on Controls and Procedures

In designing and evaluating our disclosure controls and procedures and internal control over financial reporting, management recognizes that disclosure controls and procedures and internal control over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of those controls and procedures are met. Additionally, in designing disclosure controls and procedures and internal control over financial reporting, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. 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 control system, misstatements due to error or fraud may occur and not be detected.

Changes in Internal Control over Financial Reporting

During the quarter ended March 31, 2024, there was no change in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information

Item 1. Legal Proceedings

Refer to Note 7 – Commitments and Contingencies of the Notes to Unaudited Condensed Consolidated Financial Statements for information regarding legal proceedings and other similar matters in which we may be involved from time to time, which applicable information is incorporated herein.

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. Risk factors that affect our business and financial results are discussed in Part I, Item 1A under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended September 30, 2023, filed with the SEC on December 29, 2023 and amended on January 29, 2024 (“2023 Annual Report”) and in Part II, Item 1A under the caption “Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended December 31, 2023, subject to the updates as set forth below (“2024 Q1 Report”). You should consider the following risks and those described in the 2023 Annual Report and the 2024 Q1 Report, together with all other information in this report, including our unaudited condensed consolidated financial statements as of and for the quarter ended March 31, 2024 and related notes included elsewhere in this report ("Consolidated Financial Statements"). These risks and uncertainties, some of which have occurred and any of which may occur in the future, could have a material adverse effect on our business, financial condition, results of operations, cash flows, and prospects. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business, financial condition, results of operations, cash flows, and prospects. Other than the risk factors set forth below and in the 2024 Q1 Report, there have been no material changes to the risk factors described in our 2023 Annual Report.

Risks Related to the Proposed Tender Offer by K1

If K1 fails to complete its tender offer for our capital stock within the expected timeframe, or at all, our stock price, business, results of operations and financial condition could be adversely affected.

On February 15, 2024, K1 Investment Management, LLC (“K1 Investment”), through Meridian Bidco LLC, a newly formed affiliate of K1 Investment (“Bidco,” and together with K1 Investment, “K1”), as manager of K5 Private Investors, L.P., made a public unsolicited proposal to acquire all of the issued and to be issued share capital of the Company (the “Tender Offer”).

We cannot assure you that K1 will complete its tender offer for our share capital. If the proposed Tender Offer is not completed, we will be subject to several risks. Because the current trading price of our Ordinary Shares may reflect, among other things, a market assumption that the Tender Offer will be completed, failure to complete the Tender Offer could adversely affect the price of our Ordinary Shares. Also, we may incur significant costs in connection with the Tender Offer, including the diversion of management resources that would have otherwise been spent on our business and other opportunities that could have been beneficial to us, for which we will have received little or no benefit if the Tender Offer is not completed. If our management is unable to expend the necessary time and resources on our business, our results of operations could be negatively impacted. Additionally, actions taken by the Company in connection with the Tender Offer could result in litigation against the Company, which may result in further significant costs, uncertainty and distraction. A failed transaction may also result in a negative impression of the Company in the investment community.

If the proposed Tender Offer is not completed, we may be unsuccessful in completing an alternative transaction on terms that are as favorable as the terms of the proposed Tender Offer with K1, or at all, and we may otherwise be unable to continue to operate our business. Our board of directors may decide to pursue a dissolution and liquidation of the Company. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such liquidation as well as the amount of cash that will need to be reserved for commitments and contingent liabilities.

K1 has not commenced the proposed Tender Offer and the closing of the proposed Tender Offer may be delayed or may not occur at all. Our board of directors may elect to pursue an alternative strategy, one of which may be a strategic transaction similar to the proposed Tender Offer. Attempting to complete an alternative transaction like the proposed Tender Offer would be costly and time consuming, and we can make no assurances that such an alternative transaction would occur at all. Alternatively, our board of directors may elect to continue our operations to advance the development of our programs, which would require that we obtain additional funding, and to resume our efforts to seek potential collaborative, partnering or other strategic arrangements for our program, including a sale or other divestiture of our program assets, or our board of directors could instead decide to pursue a dissolution and liquidation of our Company. In

38

such an event, the amount of cash available for distribution to our shareholders will depend heavily on the timing of such decision, and subject to the provisions of the law of Ireland, and with the passage of time the amount of cash available for distribution will be reduced as we continue to fund our operations. In addition, we may be subject to litigation or other claims related to a dissolution and liquidation. If a dissolution and liquidation were pursued, our board of directors, in consultation with its advisors, would need to evaluate these matters and make a determination about a reasonable amount to reserve. Accordingly, holders of our Ordinary Shares could lose all or a significant portion of their investment in the event of a liquidation, dissolution or winding up of the Company.

We are subject to business uncertainties and contractual restrictions while the proposed Tender Offer is pending, which could adversely affect our business and operations.

In connection with the pendency of the proposed Tender Offer, it is possible that some customers, suppliers, lenders, and other persons with whom we have a business relationship may delay or defer certain business decisions or might decide to seek to terminate, change or renegotiate their relationships with us as a result of the Tender Offer, which could negatively affect our revenues, earnings and cash flows, as well as the market price of our common stock, regardless of whether the Tender Offer is completed. Such risks may be exacerbated by delays or other adverse developments with respect to the completion of the Tender Offer.

Uncertainties associated with the Tender Offer may cause a loss of management personnel and other key employees which could adversely affect our business and results of operations.

We are dependent on the experience and industry knowledge of our officers and other key employees to execute our business plan. During the pendency of the Tender Offer, current and prospective employees of the Company may experience uncertainty about their roles if the Tender Offer is completed, which may have an adverse effect on our ability to attract or retain key management and other key personnel and in turn could adversely affect our business and results of operations.

Our business, including our management, is required to take or is restricted from taking various actions under the terms of the K1 Note, which terms the Company did not fully comply with and which matured on January 31, 2024 and was not paid off by the Company.

On January 31, 2024, that certain senior secured promissory note, dated as of October 10, 2023, and amended on January 10, 2024, issued by us to RP Ventures in the principal amount of $26.5 million (the “RP Note”) matured. On April 24, 2024, Meridian Topco LLC, an affiliate of K1 (“Topco”), purchased from RP Ventures, at a premium, all right, title, and interest in, to and under the RP Note (as assigned, the “K1 Note” and such assignment, the “K1 Assignment”). The terms of the K1 Note included various provisions that required us to take certain actions or limited our business’s ability (including that of our management) to take certain actions. These provisions covered, among others, the following matters:

•Restricting our pursuit or acceptance of any offer with respect to any recapitalization, reorganization, merger, business combination, purchase, sale, loan, notes issuance, issuance of other indebtedness or other financing or similar transaction, or to any acquisition by any person or group, which would result in any person or group becoming the beneficial owner of 2% or more of any class of equity interests or voting power or consolidated net income, revenue or assets, of the Company (in each case other than with Topco or K1), without K1’s prior written consent (“Alternate Transaction”).

•Requiring the board of directors to be set at four members, two of whom are to be selected by K1 (currently, George Mansour and Jordan Wappler).

•Restricting our ability to incur indebtedness, create certain liens, declare or distribute dividends or make certain other restricted payments, be party to a merger, consolidation, division or other fundamental change, transfer, sell or lease our assets, make certain modifications to our organizational documents or indebtedness, engage in certain transactions with affiliates, change our business, accounting or reporting practices, name or jurisdiction or organization, establish new bank accounts, and establish or acquire any subsidiary.

•Restricting our conduct of business, including regarding taking part in transactions outside of the ordinary course of our existing business, making significant payments to third parties, or issuing equity interests, without K1’s prior written consent.

•Providing K1 with ongoing comprehensive financial information and access to our books and records.

39

On January 31, 2024, the Company did not pay the outstanding principal, interest, and other applicable fees or charges due and payable on the RP Note. In addition, the Company and the guarantors under the RP Note (the “Guarantors”) failed to comply with certain other obligations under the RP Note. This nonpayment and compliance failure gave rise to events of default under the RP Note. On February 5, 2024, the Company and the Guarantors entered into a Forbearance Agreement by and among the Company, the Guarantors, and RP Ventures (the “Forbearance Agreement”), in order to allow for further negotiations with respect to a transaction to restructure all or any material part of the obligations under the RP Note and any amendment or extension of the RP Note. On February 16, 2024, K1 publicly announced a non-binding indicative proposal (the “K1 Proposal”) to acquire the entire issued and to be issued share capital of the Company through K5 Private Investors, L.P., a fund controlled by K1. The announcement of the K1 Proposal by K1 constituted an immediate event of default under the Forbearance Agreement. As a result of such default, the forbearance period under the Forbearance Agreement terminated on February 16, 2024. On February 17, 2024, RP Ventures submitted a notice to the Company regarding the Company’s default under the Forbearance Agreement and reserving RP Ventures’ right to exercise its rights and remedies under the RP Note Documents. Also on February 17, 2024, RP Ventures provided to the Company a copy of an activation notice that RP Ventures submitted to Bank of America, N.A. asserting its control rights over the Company’s deposit account. Following the K1 Assignment, K1 assumed all right, title, and interest in, to and under the RP Note Documents. There are no assurances that K1 will not exercise further remedies under the K1 Note.

With the limitations under the K1 Note, including those described above (such as the necessity of getting prior approval from K1 in many instances), we may not have the flexibility needed to take timely action necessary to manage our business effectively or make our business successful, including making changes to or taking actions outside of our current normal course of business as circumstances change. In addition, we may not be able to obtain the additional financing needed to pay off the K1 Note in a timely manner or on acceptable terms (both to us and K1), if at all. If we are unable to obtain such financing, our business would be significantly harmed and would not be able to continue in its current state, and our shareholders would be adversely impacted.

There is substantial doubt about our ability to continue as a going concern and we are currently seeking additional capital to continue and support our operations and grow our business; we cannot be certain that additional capital will be available on reasonable terms when required, or at all.

As of March 31, 2024, we had an accumulated deficit of $261.7 million and $1.8 million in cash and cash equivalents. As described in Note 1 to our Consolidated Financial Statements that are included elsewhere in this Quarterly Report on Form 10-Q, we determined that our current cash and cash equivalents would not be sufficient to fund our operations (including capital expenditure requirements and the repayment of the $26.5 million principal, together with accrued interest, of the K1 Note, which was due in January 2024) for at least 12 months from the date those Consolidated Financial Statements were issued (May 15, 2024), raising substantial doubt about our ability to continue as a going concern. We believe that our cash, cash equivalents, and cash provided by sales of database subscriptions and services will not be sufficient to meet our projected working capital and operating needs, particularly if K1 declares the principal of and accrued interest on the K1 Note to be immediately due and payable in the event that the Forbearance Agreement terminates, or an additional event of default occurs under the K1 Note, or we are unable to refinance the K1 Note. There are no assurances that we will reach an agreement with K1 with respect to restructuring all or any material part of the obligations under the K1 Note or any amendment or extension of the K1 Note or that K1 will not exercise further remedies under the K1 Note, and in such event, we cannot be certain that additional capital will be available on reasonable terms, or at all, to meet our projected working capital and operating needs, including repayment of the K1 Note. Historically, Legacy MariaDB funded its operations primarily through equity and debt financings and payments by its customers for use of its products and services. Going forward, we cannot be certain when or if our operations will generate sufficient cash to fully fund our ongoing operations or the growth of our business. In addition to general operations, we expect to require significant additional capital investments for research and development, including for the purpose of further developing our intellectual property and other proprietary technologies.

Further, we intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new features or otherwise enhance our database software and services, improve our operating infrastructure or acquire businesses and technologies. Accordingly, we will need to secure additional capital through equity or debt financings. Such additional capital may not be available on terms acceptable to us, if at all. Our access to capital through debt or equity markets have proven and could continue to prove challenging due, among other things, to recent volatility in the capital markets, the rising interest rate environment, changes in customer traffic, higher costs due to inflation, and labor shortages. If we raise additional equity-related capital, existing shareholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of Ordinary Shares. The restrictive covenants under the K1 Note also impose significant restrictions on our capital raising activities, cash management, and other financial and operational matters, and any failure to comply with these covenants could harm our business, results of operations and financial condition, including an

40

additional event of default under the K1 Note causing such note to become immediately due and payable. Any equity or debt financing that we may secure in the future could involve similarly restrictive covenants, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. If we are unable to obtain adequate financing or financing on terms that are satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly impaired, and our business may be harmed. In addition, because any decision to issue securities in the future to raise capital will depend on numerous considerations, including factors beyond our control (including, potentially, the approval of K1), we cannot predict or estimate the amount, timing or nature of any future issuance of debt or equity securities. As a result, our shareholders would bear the risk of future issuances of debt or equity securities that may reduce the value of our Ordinary Shares and dilute existing interests.

Our auditors have made reference to the material uncertainty as to our ability to continue as a going concern, and there is no assurance that we will be able to continue as a going concern.

We have determined that there is material uncertainty as to our ability to continue as a going concern and our external auditors have included a reference as to this matter in their audit report on MariaDB’s audited consolidated financial statements as of and for the fiscal year ended September 30, 2023. Our unaudited consolidated financial statements included elsewhere in this report and the audited consolidated financial statements of MariaDB as of and for the fiscal year ended September 30, 2023 were prepared assuming that we will continue as a going concern. Because we have determined that a material uncertainty exists as to whether we can continue as a going concern, it may be more difficult for us to attract investors. In addition, since we have determined that an uncertainty exists about our ability to continue as a going concern, this typically results in greater difficulty in obtaining investments and loans than businesses that do not have a qualified auditor’s opinion. Further, any investments and loans we might obtain may be on less advantageous terms. Our future is dependent upon our ability to obtain financing and upon future profitable operations from our business.

Our failure to meet the continued listing requirements of the NYSE (or another national securities exchange) or otherwise our failure to continue listing on the NYSE (or another national securities exchange) could limit the value of our securities and liquidity.

On June 28, 2023, we were notified by NYSE that we were no longer in compliance with the NYSE’s continued listing standards set forth in Section 802.01C of the NYSE Listed Company Manual (the “Manual”) because the average closing price of our Ordinary Shares was less than $1.00 per share over a consecutive 30-day trading period (the “Minimum Share Price Requirement”). The notice has no immediate impact on the listing of our Ordinary Shares and Public Warrants which could continue to trade on the NYSE unless suspended from trading or delisting occurs by NYSE, including pursuant to the notifications and related circumstances discussed below. We are closely monitoring the closing share price of our Ordinary Shares and Public Warrants and are considering all available options. We have been considering measures that could potentially help us regain compliance with the Minimum Share Price Requirement, which could include seeking to effect a reverse stock split. Any potential delisting of our Ordinary Shares and Public Warrants from the NYSE would likely result in decreased liquidity and increased volatility in our securities and may adversely affect our ability to raise additional capital or enter into strategic transactions. As of the date of this Quarterly Report on Form 10-Q, we have not yet regained compliance with the Minimum Share Price Requirement, and there can be no assurance that we will regain compliance.

On September 19, 2023, we were notified by NYSE that we were no longer in compliance with the continued listing standard set forth in Section 802.01B of the Manual because the average global market capitalization of the Company over a consecutive 30 trading-day period was less than $50 million and, at the same time, the Company’s last reported stockholders’ equity was less than $50 million (the “Market Capitalization Requirement”). In December 2023, we submitted a compliance plan describing our strategy to return to compliance with the Market Capitalization Requirement. In response to our submission, NYSE has informed us that they are monitoring our liquidity condition and other factors specifically with respect to the K1 Note, and will require an update on that matter before rendering a decision as to the sufficiency of our compliance plan. Further, our securities could be delisted pursuant to Section 802.01B of the Manual if our average market capitalization over a consecutive 30 trading-day period is less than $15 million. If our average market capitalization over a consecutive 30 trading-day period falls below $15 million, we would not have an opportunity to cure such deficiency and our securities would be suspended from trading immediately and the NYSE would initiate delisting procedures. We have been considering measures that could potentially help us regain compliance with the Market Capitalization Requirement, which also would require us to maintain an average market capitalization above $15 million, as we execute on our compliance plan, but cannot be sure that compliance will be achieved.

On October 17, 2023, we were notified by NYSE that we were no longer in compliance with certain corporate governance requirements related to the composition of our board of directors and audit committee. In connection with our issuance of the RP Note, four of our outside directors tendered their resignations from our board of directors and, to the extent

41

applicable, all committees thereof. Following those resignations, our board of directors was composed of four directors, three of which were non-independent, and we no longer satisfied the board majority independence requirements under Section 303A.01 of the Manual or the audit committee composition requirements under Section 303A.07(a) of the Manual (together, the “Board/Committee Requirements”). In connection with the K1 Assignment, two of our outside directors selected by RP Ventures resigned, and two new outside directors selected by K1 were appointed to our board of directors. Although as of the date of this Quarterly Report on Form 10-Q we have not regained compliance, we have been considering measures that could potentially help us regain compliance with the Board/Committee Requirements, but cannot be sure that compliance will be achieved.

If we fail to satisfy the continued listing requirements of the NYSE, such as the corporate governance requirements (including the Board/Committee Requirements), the round lot holders requirement, the Market Capitalization Requirement, the Minimum Share Price Requirement, or the requirement that our average market capitalization over a consecutive 30 trading-day period is greater than $15 million, the NYSE may suspend or delist our securities from trading. In addition, our securities could be delisted for other reasons. Any such suspension or delisting would likely have a negative effect on the price of our securities and would impair the ability of investors to sell or purchase securities. In the event of a delisting, we can provide no assurance that any action taken by us to restore or otherwise meet compliance with listing requirements would allow our securities to become listed again, stabilize the market price or improve the liquidity of our securities, or prevent future non-compliance with the NYSE’s or another exchange’s listing requirements. Additionally, if our securities become delisted from the NYSE and are quoted on the OTC Bulletin Board (an inter-dealer automated quotation system for equity securities that is not a national securities exchange) or not at all, the liquidity and price of our securities would likely be more limited than if they were quoted or listed on the NYSE (or another national securities exchange). In such case, investors may be unable to sell securities or do so when desired. Further, if our Ordinary Shares and Public Warrants are delisted from the NYSE and not relisted on an appropriately recognized stock exchange in the U.S. or Canada, trading in such securities will come within the charge to Irish stamp duty (currently at the rate of 1% of the higher of the price paid or the market value of the securities acquired) and, in such circumstances, may also cease to be eligible for continued deposit and holding within the facilities of DTC. At law, stamp duty is generally an obligation of the purchaser. However, in the case of a gift or transfer at an undervalue, both parties to the transfer are liable for the duty. Parties can allocate by contract, as between themselves, which of them is responsible for payment of the duty, but this will not override who is responsible at law. If DTC determined that our Ordinary Shares and Public Warrants ceased to be eligible for continued deposit and clearance within its system, transfers of such securities would need to take place outside of DTC by use of a certificated (paper based) instrument of transfer (with all relevant amounts of Irish stamp duty paid to the Irish Revenue Commissioners before a transfer could be legally registered). In addition to the amounts of stamp duty to be paid by purchasers of shares, this would likely make transfers of such securities more difficult, more time-consuming and more costly, which may also impact the price a purchaser would pay for such securities.

Restrictions under the K1 Note regarding our board of directors and our current lack of a majority independent board of directors may be deemed to adversely affect the governance of the Company, as well as the rights of other shareholders.

The K1 Note requires, among other things, that MariaDB’s board of directors be set at four members, two of whom are to be selected by K1, none of whom is required to be independent for NYSE-compliance purposes. Currently, we have three directors appointed and only one of our three directors is independent, which is insufficient for purposes of Section 303A.01 of the Manual. Two of our non-independent directors, George Mansour and Jordan Wappler, were appointed pursuant to the K1 Note and are affiliated with our current senior lender, K1. Mr. Mansour has been with K1 since 2016 and currently serves as a Partner. Mr. Wappler has been with K1 since 2018 and currently serves as Senior Vice President and Head of Legal.

In addition, the K1 Note imposes significant operational, cash management, and capital raising restrictive covenants on the Company and our business. As a result, Messrs. Mansour and Wappler are in a position to influence or control to some degree the outcome of significant operational and strategic matters requiring lender approval, including regarding, among other things, adoption of amendments to our articles of association, changes in board size and composition, cash management and disposition, investments, capital raising, and the approval of mergers and other significant corporate transactions. For example, the K1 Note requires the Board to be set at four directors. This influence and control may have, among other things, the effect of delaying or promoting a change of control and may adversely affect the voting and other rights of other shareholders, as well as our day-to-day governance.

It is further possible that the interests of our non-independent directors, particularly considering the Company’s non-independent majority, may in some circumstances potentially conflict with MariaDB’s interests and the interests of our other shareholders. For example, the K1 Note contains exclusivity provisions that restrict our ability to seek additional financing from third parties without lender approval. In addition, K1 funds are broadly in the business of making investments in technological companies and may hold and may, from time to time, in the future acquire, interests in or

42

provide advice to businesses that directly or indirectly compete with us. If we do not attract and retain a majority of qualified independent directors, the management and operations of our business could be compromised.

Organization and Description of Business

Description of Business

MariaDB plc (“MariaDB” or the “Company”) provides one of the most popular general purpose relational databases. The Company’s operations consist of programming, development and sales of software programs, applications and tools related to enterprise database software. In addition, the Company provides user support, consultation and training for the software, applications, tools, and systems. The Company is active in development of both open source and closed source software.

The Company is headquartered in Redwood City, California and Dublin, Ireland, with operations in other locations including Espoo, Finland, and Sofia, Bulgaria.

Liquidity and Going Concern

As of March 31, 2024, the Company had an accumulated deficit of $261.7 million and $1.8 million in cash and cash equivalents. The Company has determined our current cash and cash equivalents will not be sufficient to fund operations (including the repayment of the RP Note and related interest that was due in January 2024 (refer to Note 8 Debt for additional discussion)), for at least 12 months from the date these financial statements were issued (May 15, 2024), raising substantial doubt about our ability to continue as a going concern.

The Company is currently in the process of being acquired and is seeking financing to avoid any potential shortfall of cash and cash equivalents to fund operations, for at least 12 months from the date the financial statements were issued.

The Company’s need for additional capital may depend on many factors, including subscription revenue growth rate, subscription renewals, billing timing and frequency, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the need for necessary technology and operating infrastructure to support the business, the introduction of new and enhanced database features and functionality and the continued market adoption of database solutions. The Company is currently seeking additional debt financings to meet projected working capital and operational requirements. However, such additional financings are subject to market conditions, and are not within the Company’s control, and therefore cannot be deemed probable as adequate capital may not be available to the Company when needed or on acceptable terms. There is no assurance that the Company will be successful in raising additional funds. As a result, the Company has concluded that potentially raising funds does not alleviate substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern and do not include adjustments that might result from the outcome of this uncertainty.

Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying Unaudited Condensed Consolidated Financial Statements, including the accounts of MariaDB and its wholly-owned subsidiaries have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). All intercompany balances and transactions among have been eliminated in consolidation.

Revenue Recognition

Deferred revenues consist of customer contracts billed or cash received that will be recognized in the future under subscriptions existing at the balance sheet date. The current portion of deferred revenues represents amounts that are expected to be recognized within one year of the balance sheet date. As of March 31, 2024 and September 30, 2023, the balance of deferred revenue was $44.0 million and $46.6 million, respectively, which includes $11.9 million and $12.4 million of refundable customer deposits, respectively.

Revenue recognized during the three months ended March 31, 2024 and 2023 that was included in the deferred revenue beginning balance of each year was $7.1 million and $6.7 million, respectively. Revenue recognized during the six months

ended March 31, 2024 and 2023 that was included in the deferred revenue beginning balance of each year was $18.4 million and $16.7 million, respectively.

Incremental direct costs of obtaining a contract are included in prepaid and other current assets and other noncurrent assets, respectively, in the Unaudited Condensed Consolidated Balance Sheets. The current and noncurrent deferred commissions had a balance of $5.3 million and $5.6 million as of March 31, 2024 and September 30, 2023, respectively.

Concentration of Credit Risk

As of March 31, 2024, two customers accounted for 39.5% of the total balance of accounts receivable, net. As of September 30, 2023, one customer accounted for 10.5% of the total balance of accounts receivable, net. For the three and six months ended March 31, 2024 and 2023, no customer accounted for more than 10% of the Company’s total consolidated revenues.

Fair Value of Financial Instruments

As of March 31, 2024 and September 30, 2023, the carrying value of the Company’s financial instruments included in current assets and current liabilities (including cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and debt) approximate fair value due to the short-term nature of such items.

Accounts Receivable, Net

Accounts receivable, net was $8.7 million as of March 31, 2024 compared to $14.0 million as of September 30, 2023 as reported on the Unaudited Condensed Consolidated Balance Sheets.

The following table presents the changes in the allowance for credit losses for the six months ended March 31, 2024 and the year ended September 30, 2023:

	March 31, 2024		September 30, 2023
	(in thousands)

Less: write-offs, net of recoveries	(555)		(105)
Foreign currency translation	215		47
Balance, end of period	$	998	$	1,386

Prepaids and Other Current Assets

Prepaid expenses and other current assets totaled $7.6 million and $5.8 million as of March 31, 2024 and September 30, 2023, respectively.

Prepaid expenses totaled $5.6 million and $3.7 million as of March 31, 2024 and September 30, 2023, respectively. Prepaid expenses as of March 31, 2024 were primarily related to deferred legal fees related to the pending sale of the Company and deferred issuance costs in anticipation of additional financings. Prepaid expenses as of September 30, 2023 were primarily related to up-front payments made to third parties in the ordinary course of business.

Other current assets primarily consisted of deferred commission totaling $1.9 million and $1.7 million as of March 31, 2024 and September 30, 2023, respectively. Other receivables totaled $0.1 million and $0.4 million as of March 31, 2024 and September 30, 2023, respectively.

Disaggregation of Revenue

The Company believes that the nature, amount, timing and uncertainty of its revenue and cash flows and how they are affected by economic factors is most appropriately depicted through the Company’s primary geographical markets. The

Company’s primary geographical markets are North and South America (“Americas”); Europe, Middle East and Africa (“EMEA”); and Asia Pacific (“APAC”).

The following table summarizes the disaggregation of revenue by geography for the three and six months ended March 31, 2024 and 2023 respectively.

Total revenue	$	13,585	$	13,474	$	27,197	$	26,279

Revenue attributable to the United States comprised 39.6% and 42.9% of the total consolidated revenue for the three months ended March 31, 2024 and 2023, respectively. Revenue attributable to the United States comprised 41.1% and 42.6% of the total revenue for the six months ended March 31, 2024 and 2023, respectively. No other country outside of the United States comprised more than 10% of revenue for the three and six months ended March 31, 2024 and 2023. Revenue by location is determined by the billing address of the customer.

Revenue from professional services recognized at a point in time amounted to $0.3 million and $0.1 million and revenue from professional services recognized over time amounted to $1.1 million and $1.4 million for the three months ended March 31, 2024 and 2023, respectively.

Remaining Performance Obligations

Remaining performance obligations represent the aggregate amount of the transaction price in contracts allocated to performance obligations not delivered, or partially undelivered as of the end of the reporting period. Remaining performance obligations estimates are subject to change and are affected by several factors, including terminations, changes in the scope of contracts, adjustments for revenue that have not materialized and adjustments for currency. As of March 31, 2024, approximately $57.5 million of revenue is expected to be recognized from remaining performance obligations. The Company expects to recognize revenue approximately 50.8% of these remaining performance obligations over the next 12 months. The Company’s subscription contracts are recognized ratably over the contract term. Accordingly, the majority of the Company’s noncurrent remaining performance obligation is expected to be recognized in the next 13 to 36 months with the remainder recognized thereafter.

Risk-free interest rates range (weighted average)	4.89%	3.80%
Expected term range (weighted average)	2.63 years	3.13 years

Assumptions were weighted by the relative fair value of the instruments. An increase in the expected volatility, risk-free interest rates, and expected term would result in an increase to the estimated value of the warrants while an increase in the dividend yield would result in a decrease to the estimated value of the warrants.

Commitments and Contingencies

Commitments and Contingencies

The Company is subject to claims, legal proceedings, governmental actions, and assessments from time to time in the ordinary course of business, including without limitation, actions with respect to intellectual property, employment, regulatory, product liability and contractual matters. In connection with these matters, the Company regularly assesses the probability and amount (or range) of possible issues based on the developments in these matters and more generally the significance of these matters to the Company. A liability is recorded in the accompanying Unaudited Condensed Consolidated Financial Statements if it is determined that it is probable that a loss has been incurred and the amount (or range) of the loss can be reasonably estimated. The Company’s management currently does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows; provided, however, if any such matters individually or in the aggregate are decided adversely to the Company, then such matters may have a material adverse effect.

In January 2023, MariaDB received a demand letter on behalf of Houlihan Lokey Capital, Inc., a financial services company that advised Legacy MariaDB in connection with a financing transaction which closed in January 2022, for which that financial services company had provided advisory services and for which MariaDB paid its fee. The demand is for an additional fee based on a de-SPAC transaction which closed in December 2022. On July 11, 2023, Houlihan Lokey Capital, Inc. filed a lawsuit against the Company in the Supreme Court of the State of New York asserting claims against the Company for breach of contract and unjust enrichment and demand judgment against the Company in an unspecified amount exceeding $6.3 million, plus interest. The Company has answered the complaint and the matter is nearing the end of the fact discovery phase. At the current stage of the litigation, it is not possible to estimate the amount or range of possible loss that might result from an adverse judgment or a settlement of this matter. As of March 31, 2024, the Company accrued $1.0 million in other accrued expenses related to a settlement offer the Company made in this matter.

In February 2023, a second financial services company sent MariaDB an additional invoice for approximately $1.3 million under the same circumstances as described in the matter above. MariaDB denies that it owes any additional fees, and no

legal proceedings have been filed in connection with this fee claim. MariaDB intends to defend any legal proceedings that may be filed.

Loan facility agreement with RP Ventures LLC (Purchased by Meridian Topco LLC)

On October 10, 2023, the Company issued a senior secured promissory note, dated as of October 10, 2023 and amended on January 10, 2024, to RP Ventures in the principal amount of $26.5 million. RP Ventures acted as the initial Agent as defined in the RP Note (in such capacity, the “Agent”). On April 24, 2024, Meridian Topco LLC (“Meridian”), an affiliate of K1 Investment Management, LLC, a Delaware limited liability company (“K1”), purchased from RP Ventures, at a premium, all right, title and interest in, to and under the RP Note (the “RP Note Acquisition”). Further, Meridian Topco LLC became the Successor Agent (as defined in the note).

The proceeds of the RP Note were used by the Company to repay all amounts outstanding under the term loan (the "Term Loan") from European Investment Bank ("EIB"), to pay RP Ventures a nonrefundable funding fee of $132,500, to pay or reimburse RP Ventures and Runa Capital Fund II, L.P. (“Runa”) for its out-of-pocket expenses related to the RP Note transaction, and to pay for working capital purposes as approved by the Company’s board of directors.

Interest on the RP Note accrued on the principal amount at the rate of ten percent (10%) per annum and was payable commencing on January 1, 2024 and quarterly thereafter in arrears on the first business day of each calendar quarter and on the maturity date, whichever was earlier.

While the RP Note remains outstanding, the note restricts the Company from pursuing or accepting any offer with respect to any recapitalization, reorganization, merger, business combination, purchase, sale, loan, notes issuance, issuance of other indebtedness or other financing or similar transaction, or to any acquisition by any person or group, which would result in any person or group becoming the beneficial owner of 2% or more of any class of equity interests or voting power or consolidated net income, revenue or assets, of the Company, in each case other than with the note holder.

The RP Note contains certain customary representations and warranties and covenants of the Company. In addition, the Company has agreed to, among other things, provide to the note holder certain financial information, maintain minimum aggregate liquidity in an amount to be agreed upon after the Closing Date by the Board and the Agent or Successor Agent, and make disbursements and collect receivables based on budget amounts.

The RP Note limits the ability of the Company to, among other things, (i) incur indebtedness, (ii) create certain liens, (iii) declare or distribute dividends or make certain other restricted payments, (iv) be party to a merger, consolidation, division or other fundamental change, (v) transfer, sell or lease Company assets, (vi) make certain modifications to the Company’s organizational documents or indebtedness, (vii) engage in certain transactions with affiliates, (viii) change the Company’s business, accounting or reporting practices, name or jurisdiction or organization, (ix) establish new bank accounts, and (x) establish or acquire any subsidiary. In addition, without the Agent or Successor Agent’s prior consent, the Company will be restricted in, among other things, taking part in transactions outside of the ordinary course of its existing business, making certain payments, or issuing equity interests.

The RP Note provides for customary events of default, including for, among other things, payment defaults, breach of representations and certain covenants, cross defaults, insolvency, dissolution and bankruptcy, certain judgments against the Company, and material adverse changes. In the case of an event of default, the note holder may demand immediate repayment by the Company of all or part of the amounts outstanding, if any, under the RP Note.

In connection with issuance of the RP Note, the Company and MariaDB USA. Inc. and certain other of the Company’s subsidiaries (the “Guarantors”) entered into a Guarantee and Collateral Agreement, pursuant to which the Company and each Guarantor pledged substantially all of their respective assets as collateral for the RP Note and each Guarantor guaranteed to the note holder the payment of all obligations arising from the RP Note.

The RP Note was initially due on the earlier of (i) January 10, 2024, (ii) the occurrence of a "change of control" (as that term is defined in the RP Note), (iii) the occurrence of any breach of any of the documentation relating to the Company’s Term Loan or any demand for repayment of the Term Loan, and (iv) the date on which the RP Note is otherwise declared due and payable pursuant to its terms. On January 10, 2024, MariaDB entered into an amendment (the “First Amendment”) of the RP Note. The First Amendment, among and between the Company, RP Ventures, and other note parties to the RP Note, extended (i) the maturity date of the RP Note from January 10, 2024 to January 31, 2024, providing time for the Company to continue to work with parties related to the note holder on a recapitalization structure and (ii) the exclusivity period under the RP Note from January 10, 2024 to January 31, 2024. The Company paid RP Ventures a nonrefundable funding fee of $75,000 relating to the First Amendment.

On January 31, 2024, the RP Note matured. The Company did not pay the outstanding principal, interest, and other applicable fees or charges due and payable on the RP Note. In addition, the Company and the Guarantors under the RP Note failed to comply with certain other obligations under the RP Note. This nonpayment and compliance failure gave rise to events of default under the RP Note. On February 5, 2024, to allow for further negotiations with respect to a transaction to restructure all or any material part of the obligations under the RP Note and any amendment or extension of the RP Note (the “RPV Transaction”), the Company and the Guarantors entered into the Forbearance Agreement with RP Ventures. Pursuant to the Forbearance Agreement, RP Ventures agreed not to exercise its rights and remedies in relation to the defaults under the RP Note identified in the Forbearance Agreement until February 21, 2024, subject to certain limitations and conditions. In addition, the Company agreed to pay RP Ventures a forbearance fee of $100,000 and to reimburse all reasonable and documented fees and out-of-pocket expenses of RP Ventures and any of its directors, officers, employees or agents, including its counsel, consultant and any other advisors, in connection with the Forbearance Agreement, the RP Note, the Guarantee and Collateral Agreement and other related RP Note documents. Under the terms of the Forbearance Agreement, interest on amounts due under the RP Note accrues at the default rate of 2% above the otherwise-applicable non-default interest rate of 10%.

During the three and six month periods ended March 31, 2024, the Company paid RP Ventures approximately $2.0 million which included approximately $0.9 million related to principal and approximately $1.1 million of interest.

During the three months ended March 31, 2024, the Company incurred cash interest expense of $0.8 million and non-cash interest expense (amortization of debt issuance cost) of $0.6 million on the RP Note. During the six months ended March 31, 2024, the Company incurred cash interest expense of $1.4 million and non-cash interest expense (amortization of debt issuance cost) of $3.1 million on the RP Note.

The Company was not in compliance with the covenants of the RP Note as of March 31, 2024.

Loan facility agreement with European Investment Bank

The Term Loan was disbursed on October 11, 2019 and had a maturity date of October 11, 2023, at which time it was fully repaid. The Term Loan accrued interest between 6.0%-9.5% per annum, depending on MariaDB’s monthly recurring revenue. The effective interest rate on the Term Loan for the period the Term Loan was outstanding during the quarter ended December 31, 2023 and for the full quarter ended December 31, 2022 was 6.0%. As of September 30, 2023, the Company was in compliance with its debt covenants for the Term Loan.

The schedule of required principal payments remaining on debt outstanding as of March 31, 2024 is as follows:

On October 10, 2023, the Company issued the RP Note to RP Ventures, which had an initial maturity date of January 10, 24. On January 10, 2024, the RP Note maturity date was extended to January 31, 2024 pursuant to the First Amendment. On January 31, 2024, the RP Note matured. The Company did not pay the outstanding principal, interest, and other applicable fees or charges due and payable on the RP Note.

See Note 8 - Debt for additional information and terms of the RP Note, First Amendment, and the Forbearance Agreement.

SkySQL

On November 17, 2023, the Company entered into an Asset Purchase Agreement (“APA”) by and among MariaDB plc, MariaDB USA, Inc. and SkyDB, Inc. (“Sky”), completing the divestiture of the SkySQL business. Under the terms of the APA, Sky purchased all of the intellectual property, technology, operational contracts and other assets related to the SkySQL business in exchange for: (a) a to-be issued minority equity interest of ten (10%) percent of the common equity of Sky upon a third-party financing of Sky; and (b) the release and extinguishment of severance obligations for certain former Company employees who chose to become employees of Sky. All parties to the APA are subject to non-competition and non-solicitation covenants for twelve months following the effective date of the APA. Under the revenue sharing and customer transition provisions of the APA, the Company is entitled to 30% of the net revenues of any assigned customer agreement.

The Company will have no seat on the Board of Directors or any significant influence over Sky's' financial or operational decisions. The minority interest in Sky is considered immaterial to the financial statements.

The net book value of the assets related to the Sky business were all previously written off as a result of the annual goodwill impairment analysis as of September 30, 2023. In the three month period ended December 31, 2023, the Company reported a gain on the divestiture of the business of approximately $0.9 million related to the release and extinguishment of severance obligations for certain former Company employees who chose to become employees of Sky.

The divestiture did not represent a strategic shift; therefore the operating results of SkySQL did not qualify for reporting as discontinued operations.

CubeWerx

On December 30, 2023, the Company agreed to sell, assign and transfer all of the purchased contracts, intellectual property and servers/hardware of its Canadian subsidiary for a nominal amount of consideration.

As part of the divestiture, the Company is legally obligated to provide the buyer with a loan of approximately $0.6 million. The loan is interest bearing and matures in July 2029.

The Company is also required to subscribe to 10% ownership of the buyer’s newly formed company. The investment will be considered immaterial to the Company’s financial statements. The Company will have no seat on the Board of Directors or any significant influence over its financial or operational decisions.

The assets of the divested business were all previously written off as a result of the annual goodwill impairment analysis as of September 30, 2023. No gain or loss was reported on the sale of the company. The divestiture did not represent a strategic shift; therefore the operating results of the divested company did not qualify as discontinued operations.
