Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Description of Business MariaDB plc (“MariaDB” or the “Company”) was a Finnish corporation called MariaDB Corporation Ab (“Legacy MariaDB”), which was originally incorporated in Finland in 2010. As part of the Business Combination (as discussed below), the Company became an Irish public limited company that is publicly traded on the New York Stock Exchange (“NYSE”). MariaDB is one of the most popular, general purpose, relational database. The Company’s operations consist of programming, development and sales of software programs, applications and tools related to enterprise database software, including a cloud database-as-a service, and related systems and services. 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. On January 31, 2022, the Merger Agreement was signed among Angel Pond Holdings Corporation (“APHC”), a blank check company incorporated as a Cayman Islands exempted company in 2021, Mangomill plc, an Irish public limited company and wholly owned subsidiary of APHC (“Irish Holdco”), Meridian MergerSub Inc., a Cayman Islands exempted company and wholly owned subsidiary of Irish Holdco (“Merger Sub”), and Legacy MariaDB. In connection with the Merger, Merger Sub merged with and into APHC, with APHC continuing as the surviving entity and a wholly owned subsidiary of Irish Holdco (the “Irish Domestication Merger”), and Legacy MariaDB then merged with and into Irish Holdco, with Irish Holdco continuing as the surviving entity (the “Merger”). APHC was liquidated in June 2023. The Irish Domestication Merger, the Merger and the other transactions contemplated by the Merger Agreement are collectively referred to as the “Business Combination”. In connection with the Business Combination, Irish Holdco changed its name to MariaDB plc. In accordance with the Merger Agreement, certain holders of equity securities of the Legacy MariaDB (the “Equity Holders”) received shares of the Company following the Business Combination. At the time of closing, all outstanding capital shares and stock options of the Legacy MariaDB became similar securities of the Company. All the proceeds from APHC’s trust account available after any redemptions of APHC’s public shares in connection with the closing of the Business Combination and from the related PIPE Investment (as described below), after payment of transaction expenses and deferred underwriting fees, remained on the Company’s balance sheet to fund growth and working capital. On December 16, 2022 (the “Closing Date”), the Company consummated the closing of the Business Combination. The transaction was accounted for as a reverse recapitalization with Legacy MariaDB being the accounting acquirer and APHC as the acquired company for accounting purposes. Legacy MariaDB was determined to be the accounting acquirer since Legacy MariaDB’s shareholders prior to the Business Combination had the greatest voting interest in the combined entity, Legacy MariaDB comprised the ongoing operations, had the go-forward senior management, and the Legacy MariaDB shareholders were to control the board of directors and have a majority of the voting power of MariaDB plc. Accordingly, for accounting purposes, the financial statements after the closing of the Business Combination represent a continuation of the financial statements of Legacy MariaDB, with the Business Combination treated as the equivalent of Irish Holdco issuing shares for the net assets of APHC, accompanied by a recapitalization. The net assets of APHC are stated at historical cost, with no goodwill or other intangible assets recorded. Prior to the Business Combination, APHC Class A Ordinary Shares, APHC Public Units, and APHC Public Warrants were listed on the NYSE under the symbols “POND,” “POND.U,” and “POND WS,” respectively. On December 19, 2022, the Ordinary Shares and Public Warrants (as described below) began trading on the NYSE under the proposed symbols “MRDB” and “MRDB.WS,” respectively. See Note 8 Stockholders' Deficit for additional details. Certain MariaDB plc Ordinary Shares received as consideration in connection with the Business Combination (or securities convertible into or exchangeable for shares of MariaDB Ordinary Shares) could not be sold or otherwise disposed of or hedged by certain shareholders for a period of 180 days after the Closing Date, which restrictive period ended June 14, 2023. Liquidity and Going Concern As of September 30, 2023, the Company had an accumulated deficit of $249.4 million and $4.5 million in cash and cash equivalents. The Company has determined o ur current cash and cash equivalents will not be sufficient to fund our operations (including the repayment of the $26.5 million and related interest of the RP Loan due in January 2024 (see below for additional discussion) , including capital expenditure requirements for at least 12 months from the date these financial statements were issued (December 29, 2023 ), raising substantial doubt about our ability to continue as a going concern. The Company is currently seeking financing to avoid any potential shortfall of cash and cash equivalents to fund operations, including capital expenditure requirements for at least 12 months from the date the financial statements were issued.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying 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. Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to avail itself of this exemption and, therefore, for new or revised accounting standards applicable to public companies, the Company will be subject to an extended transition period until those standards would otherwise apply to private companies. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make judgements, estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such estimates include but are not limited to legal contingencies, expected period of benefit for deferred commissions, fair value measurement of financial instruments, allowances for credit losses, fair value of acquired intangible assets and goodwill, impairment analysis for goodwill and intangibles assets, useful lives of acquired intangible assets and property and equipment, stock-based compensation and accounting for income taxes. The Company based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Since future events and their effects cannot be predicted with absolute certainty, actual results could differ from current estimates. Revenue Recognition The Company derives revenues from subscriptions that require customers to pay a fee in order to access the Company’s database solutions. Contract periods with customers generally are one year with occasional contracts ranging up to three years. The Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, the Company satisfies a performance obligation. At the inception of a customer contract, the Company makes an assessment as to that customer's ability to pay for the services provided. The Company assesses collectability based on several factors, including credit worthiness of the customer along with past transaction history. In addition, the Company performs periodic evaluations of its customers’ financial condition. Most of the Company’s revenue contracts are subscription based and contain a single performance obligation. The subscription contracts typically do not offer to the customers any future rights that would constitute material rights. Contract prices are generally composed of fixed consideration for a specific period of time as the Company in general does not offer refunds, rebates, customer loyalty programs or other forms of customer incentive payments. As the Company's cloud-oriented subscription services are delivered to customers electronically and over time, revenue is generally recognized ratably over the contract terms. Historically, no significant judgment has generally been required in determining the amount and timing of revenue from the Company’s contracts with customers. Contract modifications happen when there is an upsell, where the customers subsequently enter into contract with the Company to purchase additional product offerings. Contract modifications related to upsells are accounted for prospectively. 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 September 30, 2023 and 2022, the balance of deferred revenue was $46.6 million and $31.6 million, respectively, which includes $12.4 million and $0 of refundable customer deposits, respectively. Revenue recognized during the fiscal years ended September 30, 2023 and 2022 that was included in the deferred revenue beginning balance of each year was $20.3 million and $25.5 million, respectively. Incremental direct costs of obtaining a contract, which consist of sales commissions primarily for new business and upsells, are deferred and amortized over the estimated life of the customer relationship if renewals are expected and the renewal commission is not commensurate with the initial commission. The Company elected the practical expedient to expense commissions on renewals where the specific anticipated contract term amortization period is one year or less. The Company amortizes the capitalized commission cost as a selling expense on a straight-line basis over a period of five years. The Company classifies deferred commissions as current or noncurrent based on the timing of when it expects to recognize the expense. The current and noncurrent portions of deferred commissions are included in prepaid and other current assets and other noncurrent assets, respectively, in its consolidated balance sheets. The current and noncurrent deferred commissions had a balance of $5.6 million and $4.6 million as of September 30, 2023 and 2022, respectively. Service revenue is related to the provisioning of support to customers. The service revenue is recognized as earned. Foreign Currency Translation and Re-measurement The functional currency of the Company is the Euro (EUR). The functional currency of the Company’s international subsidiaries is either the EUR or the local currency in which the international subsidiary operates. For the foreign subsidiaries where the functional currency is not the local currency, local currency denominated monetary assets and liabilities are re-measured into the functional currency at current exchange rates and foreign currency denominated nonmonetary assets and liabilities are re-measured into the functional currency at historical exchange rates. Transaction gains or losses from foreign currency re-measurement and settlements are included in other expense, net in the consolidated statements of operations and comprehensive loss. The Company’s reporting currency is the U.S. dollar. In the consolidated financial statements, the financial information of the Company and its international subsidiaries have been translated into U.S. dollars. The Company uses the exchange rate as of each balance sheet date to translate assets and liabilities and the average exchange rate during the period to translate revenue and expenses into U.S. dollars. Stockholders’ deficit is translated at historical rate. Translation gains or losses resulting from translating foreign functional currency financial statements into U.S. dollars are included in accumulated other comprehensive loss as a component of stockholders’ deficit. The Company is exposed to fluctuations between the U.S. dollar and the EUR. The change in the value of the EUR relative to the U.S. dollar may affect the Company’s financial results reported in the U.S. dollar terms without giving effect to any underlying changes in its business or results of operations. Cash and Cash Equivalents Cash and cash equivalents include cash held in our bank accounts as well as highly liquid investments with an original maturity of three months or less at acquisition. The Company maintains such investments in immaterial money market funds, which have readily determinable fair values using quoted prices in active markets. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents and accounts receivable. Substantially all of the Company’s cash and cash equivalents are maintained at financial institutions in the United States and Finland. Cash and cash equivalents can exceed amounts insured by the Federal Deposit Insurance Corporation and Deposit Guarantee schemes of up to $250,000 and €100,000, respectively. The Company’s accounts receivable are derived from revenue earned from customers located in the U.S. and internationally. Customer credit risk is managed by the business and is subject to the Company’s established policy and procedures relating to customer credit risk management. The credit quality of a customer is assessed based on an extensive credit rating scorecard and individual credit limits are defined in accordance with this assessment. Outstanding customer receivables and contract assets are regularly monitored. The Company evaluates the concentration of risk with respect to trade receivables as low, as its customers are in several geographical regions and industries and operate in largely independent markets. As of September 30, 2023, one customer accounted for 10.5% of the total balance of accounts receivable. As of September 30, 2022, no customer accounted for more than 10% of the total balance of accounts receivable. For the fiscal years ended September 30, 2023 and 2022, no customer accounted for more than 10% of the Company’s total consolidated revenues. Fair Value of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, as described below, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices for identical or similar assets and liabilities in markets that are not active or observable inputs other than quoted prices in active markets for identical or similar assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These include the Black-Scholes option-pricing model which uses inputs such as expected volatility, risk-free interest rate and expected term to determine fair market valuation. As of September 30, 2022, the Company’s investment securities consisted of $26.0 million in United States (“U.S.”) Treasury Bills, all of which matured by December 31, 2022. During the fiscal year ended September 30, 2022, the Company changed the classification of its U.S. Treasury Bills from held-to-maturity to available-for-sale based on its intent to sell the securities. The Company’s available-for-sale marketable securities are recorded at fair value. Any unrealized gains or losses are recorded in accumulated other comprehensive loss within the consolidated balance sheets. Any realized gains and losses are recorded as a part of other income (expense), net in the consolidated statements of operations and comprehensive loss in accordance with ASC 320 “Investments – Debt and Equity Security.” The total proceeds received from disposal of available-for-sale securities during the fiscal year ended September 30, 2023 and 2022 was $25.9 million and $9.4 million, respectively. The total realized gain during the fiscal year ended September 30, 2023 and 2022 was $0.9 million and $0.1 million, respectively. The Company considers all investments with original maturities of greater than three months and less than 12 months to be short-term investments. There were no available-for-sale-securities outstanding as of September 30, 2023. The fair value of available-for-sale securities outstanding as of September 30, 2022 was as follows (in thousands): Amortized Gross Gross Effect of Fair Value U.S. Treasury Bills $ 25,962 $ 2,177 $ — $ (2,140) $ 25,999 Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification at each reporting date. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the years presented. As of September 30, 2023 and 2022, 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, deferred revenue) approximate fair value due to the short-term nature of such items. The money market funds within cash equivalents and available-for-sale securities are classified within Level 1 of the hierarchy as the values are derived from quoted prices in active markets. The Company’s warrants are recorded at fair value on a recurring basis. The estimation of fair value for these investments requires the use of significant unobservable inputs, and these inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. As a result, the Company classifies the Public Warrants (as defined in Note 7) as level 1, the Private Warrants (as defined in Note 7) as level 2, and the Kreos Rollover Warrants (as defined in Note 7) as level 3, within the fair value hierarchy. Refer to Note 7 Warrants for further details on the valuation inputs. We have not elected the fair value option as prescribed by ASC 825, The Fair Value Option for Financial Assets and Financial Liabilities, for our financial assets and liabilities that are not otherwise required to be carried at fair value. Under ASC 820, Fair Value Measurements and Disclosures, material financial assets and liabilities not carried at fair value, such as our long-term debt and accounts receivable and payable, are reported at their carrying values. Accounts Receivable, Net Accounts receivable is recognized if and when an amount of consideration is due from a customer and is unconditional (i.e., only the passage of time is required before payment of the consideration is due). Accounts receivable are non-interest bearing and are generally on terms of 30 to 60 days. Generally, trade receivables are written-off if past due for more than 180 days and are not subject to enforcement activity. Accounts receivable presented on the consolidated balance sheets are adjusted for any write-offs and net of allowance for credit losses. An analysis is performed at each reporting date using a provision matrix and customer specific data to measure expected credit losses. The Company applies a simplified approach in calculating current expected credit losses ("CECL"). Therefore, the Company does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime CECLs at each reporting date. The Company has established a provision matrix that is based on the Company’s historical observed default rates. The Company will calibrate the historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment. The Company’s estimates of the allowance for credit losses may not be indicative of the Company’s actual credit losses requiring additional charges to be incurred to reflect the actual amount collected. The following table presents the changes in the allowance for credit losses for the fiscal years ended September 30, 2023 and 2022: September 30, September 30, (in thousands) Balance, beginning of period $ 642 $ 394 Add: provision for credit losses 802 400 Less: write-offs, net of recoveries (105) (94) Foreign currency translation 47 (58) Balance, end of period $ 1,386 $ 642 Prepaids and Other Current Assets Prepaid expenses and other current assets totaled $5.8 million and $15.5 million as of September 30, 2023 and 2022, respectively. Prepaid expenses totaled $3.7 million and $13.5 million as of September 30, 2023 and 2022, respectively. Prepaid expenses as of September 30, 2023 were primarily related to up-front payments made to third parties in the ordinary course of business. As of September 30, 2022, prepaid expenses were primarily related to deferred equity issuance costs in anticipation of the Business Combination, which were reclassified to equity in the first quarter of fiscal year 2023. Other current assets primarily consisted of deferred commission totaling $1.7 million and $1.5 million as of September 30, 2023 and 2022, respectively. Other receivables totaled $0.4 million and $0.5 million as of September 30, 2023 and 2022, respectively. Warrant Liabilities As discussed in Note 7 Warrants, the Legacy MariaDB preferred share warrants were either settled or converted into Ordinary Share warrants through the Business Combination (referred to as the “Legacy MariaDB Warrants”). Further, as discussed in Note 7 Warrants, the Company assumed Private Warrants and Public Warrants th rough the Business Combination. The Company accounts for its warrants in accordance with the guidance contained in ASC 815-40. Such guidance provides that because these warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a derivative liability. The warrants are measured at fair value on a recurring basis. The Company estimates the fair value of the Legacy MariaDB Warrants using the Black-Scholes option pricing model and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, as well as assumptions for expected volatility, expected life, yield, and risk-free interest rate. The Company estimates the fair value of th e Public Warrants based on the observable market quote in an active market under the ticker MRDB.WS. As the transfer of Private Warrants to anyone outside of a small group of individuals who are permitted transferees would result in the Private Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Warrant is equivalent to that of each Public Warrant, with an insignificant adjustment for short-term marketability restrictions. The Company continues to adjust the liability for changes in fair value until the earlier of the exercise of the warrants, the expiration of the warrants, or until such time as the warrants are no longer considered a liability. Segment Information Operating segments are based upon the Company’s internal organizational structure, the manner in which its operations are managed, the criteria used by its Chief Operating Decision Maker (“CODM”) to evaluate segment performance and the availability of separate financial information to be regularly reviewed for resource allocation and performance assessment. The Company has determined its CODM to be the Chief Executive Officer (“CEO”). The CEO reviews financial information presented on a consolidated basis for purposes of managing the business, allocating resources, making operating decisions and assessing financial performance. On this basis, the Company is organized and operates as a single segment within the Software-as-a-Service ("SaaS") space. As of September 30, 2023, the Company has a single operating and reportable segment. Stock-Based Compensation Employees (including senior executives) and directors of the Company have been granted share-based payments in the form of stock options and restricted stock unit awards (the "RSUs"). Stock-based compensation costs related to stock options are calculated based on the fair value of the share-based award on the date of grant using the Black-Scholes option-pricing model and stock-based compensation costs for RSUs are calculated based on the fair value using the closing price of the Company's Ordinary Shares on the date of grant. Stock-based compensation costs are recognized as compensation expense in the accompanying consolidated statement of operations and comprehensive loss on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related input assumptions requires judgment, including estimating the fair value of Ordinary Shares, share price volatility, and expected term, which impact the fair value estimated and the expense that will be recognized. Legacy MariaDB granted options to its employees, members of the board as well as some advisors under the following plans, collectively (the “Legacy Plans”): • Summer 2022 USA Share Option Plan • Global Share Option Plan 2017 • Global Share Option Plan 2017 USA • Global Share Option Plan 2014 Europe • Global Share Option Plan 2014 USA • Global Share Option Plan 2012 Europe • Global Share Option Plan 2012 USA • Global Share Option Plan 2012 France • Global Share Option Plan 2010 Europe • Global Share Option Plan 2010 USA • Global Share Option Plan 2010 France In connection with the Business Combination, each equity award issued and outstanding under the Legacy Plans listed above (each, a "Legacy MariaDB Equity Award") was automatically converted into an equity award to be settled in MariaDB plc Ordinary Shares generally on the same terms and conditions as were applicable to such Legacy MariaDB Equity Award immediately prior to the Business Combination (other than adjustments to the number of shares and exercise price based on the Exchange Ratio). As of September 30, 2023 , stock options and RSUs are the o nly types of share-based payment that have been granted under the Company’s plans. On December 18, 2022, MariaDB plc approved and adopted a new plan, the MariaDB plc 2022 Equity Incentive Plan, which became effective immediately as of closing of the Business Combination on December 16, 2022 as described in Note 9 Stock-Based Compensation. The type of awards permitted under the new plan include stock options, stock appreciation rights, stock awards, restricted stock unit awards, performance awards and other stock awards. Computation of Loss Per Share Basic loss per share is calculated by dividing the net loss by the weighted-average number of Ordinary Shares outstanding during the period. Diluted loss per share is calculated by dividing the loss by the weighted-average number of Ordinary Shares and potentially dilutive securities outstanding during the period. Potentially dilutive Ordinary Shares consist of incremental Ordinary Shares issuable upon exercise of stock options, restricted stock and shares issuable upon the conversion of warrants. The dilutive effect of outstanding shares is reflected in diluted earnings per share by application of the treasury stock method, or the if-converted method. Research and Development Costs incurred in research and development, which includes software engineering expenses, such as salaries and related benefits, stock-based compensation, depreciation, professional services and overhead expenses related to the general development of the Company’s products, are expensed as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. The Company has not capitalized any software development costs since the period between establishing technological feasibility and general customer release is relatively short and as such, these costs have not been material. Comprehensive Loss Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, including foreign currency translation adjustments and unrealized gains and losses on marketable securities. Other comprehensive loss, net of tax, is presented on the Consolidated Statements of Operations and Comprehensive Loss. Cost of Revenue Cost of subscription revenue consists of expenses for providing our database products and services to our customers. These expenses include third-party cloud infrastructure costs, network and bandwidth costs, credit card processing fees, and revenue share associated with selling third-party software tools. Cost of services revenue primarily includes personnel-related costs, including salaries, bonuses, benefits, and stock-based compensation, for employees associated with our professional services, including our remote database administration and enterprise architect services, and travel-related costs. Leases The Company leases office space, domestically and internationally, under operating leases. The Company’s leases have remaining lease terms of less than one year. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheets. The Company does not have any finance leases. The Company determines if an arrangement is a lease, or contains a lease, at inception. The Company assesses all relevant facts and circumstances in making the determination of the existence of a lease. For leases with terms greater than 12 months, the Company records the related asset and obligation at the present value of lease payments over the term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments, and uses the implicit rate when readily determinable. Many of the Company’s leases include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the Company does not separate non-lease components from lease components. Operating lease costs are included in research and development and selling, general and administrative costs on the statement of operations. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination. Goodwill is not subject to amortization, but is subject to at least an annual assessment for impairment. The Company performs its impairment analysis of goodwill on an annual basis during the fourth quarter of the fiscal year unless conditions arise that warrant a more frequent evaluation. When goodwill is assessed for impairment, the Company has the option to perform an assessment of qualitative factors of impairment (optional assessment) prior to necessitating a quantitative impairment test. Should the optional assessment be used for any given year, qualitative factors to consider for a reporting unit include: cost factors; financial performance; legal, regulatory, contractual, political, business, or other factors; entity specific factors; industry and market considerations; macroeconomic conditions; and other relevant events and factors affecting the reporting unit. If the Company determines in the qualitative assessment that it is more likely than not that the fair value of the reporting unit is less than its carrying value, a quantitative test is then performed. Otherwise, no further testing is required. For a reporting unit tested using a quantitative approach, the Company compares the fair value of the reporting unit with the carrying amount of the reporting unit, including goodwill. The fair value of the reporting unit is estimated using an income approach. Under the income approach, the Company measures fair value of the reporting unit based on a projected cash flow method using a discount rate determined by its management which is commensurate with the risk inherent in its current business model. The Company’s discounted cash flow projections are based on its annual financial forecasts developed internally by management for use in managing its business. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, then the amount of goodwill impairment will be the amount by which the reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Due to the approval and implementation of the restructuring plan (refer to Note 17 ("Subsequent Events") for additional information) and the deterioration of the price of the Company’s Ordinary Shares and the resulting reduced market capitalization of the Company, the Company determined that as of fiscal year end September 30, 2023, it incurred an impairment charge of $7.8 million associated with its acquisitions of Clustrix/Xpand in September 2018 and CubeWerx Inc. in August 2022. This determination was reached based on the results of an updated financial plan for the Company’s business and economic outlook, which the Company conducts as part of its annual strategic planning cycle. For the fiscal year ended September 30, 2022, the Company did not recognize any impairment charge for goodwill. Intangible Assets Intangible assets are comprised of acquired technology, trademarks and contractual relationships. Identifiable intangible assets resulting from the acquisitions of entities accounted for using the purchase method of accounting are estimated by management based on the fair value of assets received. Identifiable definite-lived intangible assets are being amortized over the period of estimated benefit using the straight-line method and estimated useful lives of 3 to 8 years. We perform periodic reviews of significant finite-lived identified intangible assets to determine whether facts and circumstances indicate that the carrying amount may not be recoverable. These reviews can be affected by various factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our forecasts for specific product lines. Periodically, we also evaluate the estimated remaining useful lives of purchased intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization. We may adjust the period over which these assets are amortized to reflect the period in which they contribute to our cash flows. At September 30, 2023, the Company determined that intangible assets were impaired and as a result the Company recognized an impairment charge of approximately $0.9 million. For the fiscal year ended September 30, 2022, the Company did not recognize any impairment charge for intangible assets. Business Combinations The Company applies the provisions of ASC 805, Business Combinations, in accounting for its acquisitions. To determine whether transactions should be accounted for as asset acquisition or business combination, the Company evaluates whether substantially all of the fair value of gross assets included in a transaction is concentrated in a single asset (or a group of similar assets), resulting in an asset acquisition; if that is not the case, the resulting accounting is as a business combination. In an asset acquisition, the cost of acquiring the asset group, including transaction costs, is allocated to the acquired assets or assumed liabilities based on their relative fair values without giving rise to goodwill. In a business combination, the Company recognizes separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as any contingent consideration, where applicable, its estimates are

Accounting Changes and Error Corrections [Abstract]
Revision of Prior Period Financial Statements	Revision of Prior Period Financial Statements Subsequent to the issuance of the unaudited condensed consolidated financial statements for the quarterly fiscal period ended December 31, 2022, the Company identified an error in its accounting of incremental costs of obtaining customer contracts. Certain incremental costs that qualify for capitalization and amortization over the expected period of benefit were inappropriately expensed in the period the commission was earned, resulting in an overstatement of operating expenses in the previously issued financial statements. As a result, the Company has revised the financial statements as of and for the fiscal year ended September 30, 2022 from amounts previously reported. Management determined the error was immaterial to the previously issued consolidated financial statements. The following tables present a summary of the revision to the Company’s previously issued historical financial statements as of and for the periods noted.

Revenue from Contract with Customer [Abstract]
Revenue	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 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 fiscal years ended September 30, 2023 and 2022 respectively. Fiscal Year Ended September 30, 2023 2022 (in thousands) EMEA $ 19,166 $ 16,092 Americas 24,285 20,933 APAC 9,662 6,660 Total revenue $ 53,113 $ 43,685 Revenue attributable to the Company's country of domicile upon completion of the business combination, Ireland, comprised 0.4% and 0.1% of the total revenue for the fiscal years ended September 30, 2023 and 2022, respectively. Revenue attributable to the United States comprised 41.7% and 44.2% of the total revenue for the fiscal years ended September 30, 2023 and 2022, respectively. No other country outside of the United States comprised more than 10% of revenue for the fiscal years ended September 30, 2023 and 2022. Revenue by location is determined by the billing address of the customer. Revenue from professional services recognized at a point in time amounted to $0.6 million and $0.2 million and revenue from professional services recognized over time amounted to $5.4 million and $5.0 million for the fiscal years ended September 30, 2023 and 2022, respectively. Remaining Performance Obligations Remaining performance obligations represent the aggregate amount of the transaction price in contracts allocated to performance obligations not delivered, partially undelivered, or unbilled 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 September 30, 2023, approximately $56.5 million of revenue is expected to be recognized from remaining performance obligations. The Company expects to recognize revenue approximately 52.7% 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.

Business Combinations [Abstract]
Acquisition	Acquisition On August 2, 2022, the Company entered into a stock purchase agreement and completed the acquisition of 100% of the outstanding equity of Sector 42 Technologies, Inc. (“Sector 42”) a corporation registered under the laws of the Province of Ontario, and CubeWerx Inc. (“CubeWerx”), a corporation registered under the laws of the Province of Ontario, for a total purchase price of $3.9 million consisting of cash consideration, deferred consideration, and equity consideration in the form of 539,233 MariaDB plc Ordinary Shares as adjusted for the Exchange Ratio. The purchase price is subject to certain customary adjustments (including closing date indebtedness and net working capital adjustments). The net working capital adjustment was finalized in June 2023, resulting in an increase to the purchase price of $0.1 million, which was recorded to goodwill. The components of the preliminary fair value of consideration transferred are as follows ($ in thousands): Cash consideration $ 1,661 Equity consideration 2,056 Deferred consideration 100 Net working capital adjustment 57 Total fair value of consideration transferred $ 3,874 Of the total purchase consideration, $0.1 million of cash was deferred by the Company for potential breaches of representations and warranties. The amount, net of any claims for such indemnifiable matters, is scheduled to be paid in cash to shareholders of CubeWerx and Sector 42 18 months after the acquisition date. As of September 30, 2023, no additional amounts were paid to the shareholders of CubeWerx. The following table summarizes the preliminary purchase price allocation as of the acquisition date ($ in thousands): Initial Amounts Measurement Period Preliminary Amounts Cash and cash equivalents $ 5 — $ 5 Accounts receivable, net 47 — 47 Property and equipment, net 4 — 4 Intangible assets, net 670 — 670 Other assets 103 — 103 Total identifiable assets acquired $ 829 — $ 829 Accounts payable 40 — 40 Accrued expenses 16 — 16 Deferred tax liability — $ 238 238 Other liabilities 39 — 39 Total identifiable liabilities assumed $ 95 $ 238 $ 333 Total identifiable net assets $ 734 (238) $ 496 Goodwill $ 3,140 238 $ 3,378 With this acquisition, the Company acquired the technology of managing and publishing geospatial data via open web services for customer organizations. The fair values of the assets acquired and liabilities assumed and the related acquisition accounting are based on management's estimates and assumptions. The following table summarizes the final valuation of acquired intangible assets and estimated useful lives as of the acquisition date ($ in thousands): Estimated remaining Fair Value Customer Relationships 8.0 $ 130 Developed Technology 5.0 470 Trademarks 3.0 70 Total identifiable intangible assets $ 670 Since the acquisition date, the operating results of CubeWerx and Sector 42 were included in the Company’s consolidated financial statements. The acquisition did not have a material impact on the Company’s consolidated financial statements. Accordingly, revenue, net income, and pro forma financial information have not been presented. Acquisition-related transaction costs associated with the CubeWerx and Sector 42 acquisition were immaterial. Due to the approval and implementation of the restructuring plan (refer to Note 17 ("Subsequent Events") for additional information) and the deterioration of the price of the Company’s Ordinary Shares and the resulting reduced market capitalization of the Company, it was determined that as of fiscal year end September 30, 2023, the Company would record an impairment charge of approximately $0.9 million, which included the full carrying amount of the Company's intangible assets associated with its acquisition of CubeWerx and Sector 42. In addition, the goodwill associated with the acquisition was also impaired.

Goodwill	Goodwill The following table summarizes the change in goodwill for the fiscal year ended September 30, 2023: (in thousands) September 30, 2022 $ 7,535 Measurement period adjustments 295 Impairment charge (7,830) September 30, 2023 $ — As described in Note 5 Acquisition, the Company continued to refine the initial estimates and assumptions included in the valuation studies necessary to assess the fair values of the tangible and intangible assets acquired and liabilities assumed in the CubeWerx and Sector 42 acquisition, and the amount of goodwill to be recognized as of the acquisition date. The measurement period adjustment recorded during the fiscal year ended September 30, 2023 resulted from changes in the deferred tax liability, amount of foreign tax expense owed by the Company, and net working capital adjustments. Due to the approval and implementation of the restructuring plan (refer to Note 17 ("Subsequent Events") for additional information) and the deterioration of the price of the Company’s Ordinary Shares and the resulting reduced market capitalization of the Company, the Company determined for the fiscal year ended September 30, 2023, it would incur an impairment charge of approximately $7.8 million associated with its acquisitions of Clustrix/Xpand in September 2018 and CubeWerx Inc. in August 2022. This determination was reached based on the results of an updated financial plan for the Company’s business, economic outlook, and market capitalization, which the Company conducts as part of its annual goodwill impairment analysis and strategic planning cycle.

Warrants	Warrants Kreos Rollover Warrants Legacy MariaDB entered into a €4 million loan facility agreement with Kreos Capital IV (“Kreos”), which was repaid in full. In connection with the Kreos loan facility, Legacy MariaDB issued a total of 835,185 warrants entitling subscription for Series B Preferred Shares (“Kreos Rollover Warrants”). Each of those warrants entitled the holder to subscribe for one Series B Preferred Share at a subscription price of €0.5220 per share. In connection with the closing of the Business Combination on December 16, 2022, the warrants issued in connection with the Kreos loan facility agreement were rolled over to an amended and restated warrant agreement entered into on September 8, 2022, pursuant to which the Company assumed all rights and obligations from Legacy MariaDB. The warrants were also amended to adjust the number of Ordinary Shares issuable on exercise of the warrants and the exercise price in proportion to the Exchange Ratio. As a result of these adjustments, the Kreos Rollover Warrants became exercisable for a total of 190,559 Ordinary Shares and are exercisable at a price per share of €2.288. The warrant holder may exercise the warrant by either paying cash equal to the exercise price or in a cashless manner as described in the warrant agreement. As of September 30, 2023, Kreos Rollover Warrants exercisable for 190,559 Ordinary Shares remained outstanding. 2020 Series C Warrants In September 2020, Legacy MariaDB entered into an investment agreement with several investors to issue Series C Preferred Shares. In addition to the issuance of 3,445,912 shares of Series C Preferred Shares, Legacy MariaDB issued a total of 3,445,912 warrants entitling subscription of Series C Preferred Shares (“2020 Series C Warrants”). Each warrant entitled the holder to purchase one Series C Preferred Share at a subscription price of €1.1859. As of September 30, 2022, 587,769 warrants had been exercised and 2,858,143 remained outstanding. In connection with the Business Combination, the holders of these warrants were given the opportunity to exercise their warrants to subscribe for Series C Preferred Shares, on a one-for-one basis. Prior to the completion of the Business Combination and the effects of the exchange ratio, 2,365,078 of these warrants were exercised and 493,065 were not exercised. The subscription rights under the warrant agreements for all unexercised warrants terminated as of the date of the Business Combination. 2017 Series C Warrants In April 2017, Legacy MariaDB entered into a €25 million maximum loan facility with European Investment Bank (“EIB”), including the issuance of a capital loan tranche of €10 million. In October 2019, Legacy MariaDB entered into a €15 million term loan tranche with EIB. In connection with the capital loan tranche, Legacy MariaDB issued a total of 5,326,623 warrants entitling subscription of Series C Preferred Shares (“2017 Series C Warrants”). Each warrant entitled the holder to subscribe for one Series C Preferred Share at a subscription price of €0.01. These warrants provided for a put option that the holder of the warrants could exercise beginning 30 days prior to the maturity of the capital loan to purchase a variable number of shares at fair value for an amount up to €8 million. On August 8, 2022, Legacy MariaDB received written notice from EIB exercising its put option on their 2017 Series C Warrants and requiring Legacy MariaDB to repurchase 5,000,194 warrants entitling subscription of Series C Preferred Shares, at the maximum purchase price of €8 million. Legacy MariaDB repurchased the warrants within 30 days after receipt of the notice from EIB. On August 17, 2022, a definitive agreement was entered into with EIB to repurchase for cash the remaining incremental 2017 Series C Warrants for 326,429 shares prior to the completion of the Business Combination or shortly thereafter, at a settlement price to be determined pursuant to the Finnish Companies Act, if EIB elected not to exercise their warrants for Series C Preferred Shares prior to the completion of the Business Combination. The remaining 326,429 option rights were redeemed on the completion of the Business Combination at a redemption price of €1.19 per option for a total of €0.4 million. Public and Private Warrants As a result of the Business Combination, the Company is deemed to have assumed 7,310,297 warrants for Ordinary Shares that were held by Angel Pond Partners LLC, APHC's sponsor (the “ Sponsor ” ) at an exercise price of $11.50 (the “ Private Warrants ” ) and 8,850,458 warrants for Ordinary Shares held by APHC’s shareholders at an exercise price of $11.50 (the “Public Warrants”, and together with the Private Warrants, the “Public and Private Warrants”). In accordance with the warrant agreements, the Public and Private Warrants expire five years after the completion of the Business Combination. Public and Private Warrant Terms Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. Once the Public Warrants became exercisable, the Company became able to redeem the Public Warrants for redemption: • in whole and not in part; • at a price of $0.01 per Public Warrant; • upon not less than 30 days’ prior written notice of redemption to each warrant holder; and • if, and only if, the reported last sale price of the Ordinary Shares equals or exceeds $18.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalization and the like) for any 20 trading days within a 30-trading day period ending three or • in whole and not in part; • at a price of $0.10 per Public Warrant; • upon not less than 30 days’ prior written notice of redemption to each warrant holder; provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to the table in “Warrants- Redemption of warrants when the price per Ordinary Share equals or exceeds $10.00” based on the redemption date and the “fair market value” of the Ordinary Shares; • if, and only if, the reported last sale price of the Ordinary Shares equals or exceeds $10.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalization and the like) for any 20 trading days within a 30-trading day period ending three • provided that the Private Warrants must also be concurrently called for redemption on the same terms as the outstanding public warrants if the reported last sale price of the Ordinary Shares is less than $18.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalization and the like) for any 20 trading days within a 30-trading day period commencing no earlier than the date the warrants become exercisable and ending on the third business day before the date on which the Company sends the notice of redemption to the warrant holders. The Company may not exercise its redemption right if the issuance of Ordinary Shares upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration or qualification. The exercise price and number of Ordinary Shares issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, or recapitalization, reorganization, merger or consolidation. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of Ordinary Shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. The Private Warrants are identical to the Public Warrants, except that the Private Warrants and Ordinary Shares issuable upon the exercise of the Private Warrants were not transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Warrants are exercisable on a cashless basis and non-redeemable so long as they are held by the initial purchasers or their permitted transferees (except when the price per Ordinary Share equals or exceeds $10.00). If the Private Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Warrants are redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. These warrants expire between May 2026 and December 2027 if expiration is not accelerated as set out in the terms and conditions of the warrants. Warrant information in the below table is presented as having been converted by the Exchange Ratio as of September 30, 2022.

Fair values of the remaining warrants and option rights were determined using the Black-Scholes option-pricing model with the following input assumptions: Fiscal Year Ended September 30, 2023 2022 Expected volatility range (weighted average) 44.07% 40.25% to 48.99% (46.71%) Dividend yield 0.00% 0.00% Risk-free interest rates range (weighted average) 4.89% 3.85% to 4.24% (4.15%) Expected term range (weighted average) 2.63 years 3.03 years to 9.83 years (4.56 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.

Stockholders' Deficit	Stockholders’ Deficit Recapitalization On the Closing Date, Legacy MariaDB received $10.5 million in net proceeds from the PIPE Investment and issuance of Ordinary Shares upon the consummation of the Business Combination, net of fees and expenses paid at closing. As of December 16, 2022, the Company reclassified $14.9 million of deferred offering costs to Additional paid in capital as an offset against proceeds on the Company’s consolidated balance sheet, which consisted of legal, accounting, and other professional services directly related to the Business Combination. During the fiscal year ended September 30, 2023, the Company made certain adjustments, increasing deferred offering costs by $0.7 million, to $15.6 million in total. The cash outflows related to these costs were presented as financing activities on the Company’s consolidated statement of cash flows. On the Closing Date, each Legacy MariaDB preferred share issued and outstanding prior to the effective time of the Business Combination was converted into common shares of Legacy MariaDB and each holder of Legacy MariaDB common shares received approximately 0.22816 MariaDB plc Ordinary Shares, par value $0.01 per share. The shares and net loss per Ordinary Share prior to the Business Combination have been retroactively adjusted to reflect the impact of the exchange ratio of approximately 0.22816 (“Exchange Ratio”), applied to the Legacy MariaDB common shares that were automatically canceled and converted into the right to receive a number of Ordinary Shares. In connection with the Business Combination, each Legacy MariaDB preferred share issued and outstanding prior to the effective time of the Business Combination was converted into common shares of Legacy MariaDB in accordance with Legacy MariaDB’s articles of association and shareholders’ agreement. Each of the Public Warrants and Private Warrants that were not exercised at the time of the Business Combination was assumed by the Company and represents the right to purchase one Ordinary Share upon exercise of such warrant. PIPE Investment On January 31, 2022, concurrently with the execution of the Merger Agreement, APHC and Irish Holdco entered into subscription agreements with certain investors (the “PIPE Investors”) to which such investors collectively subscribed for an aggregate of 1,915,790 Ordinary Shares for $9.50 per share for aggregate gross proceeds of $18.2 million (the “PIPE Investment”).

Options granted under both plans are exercisable over a maximum term of 10 years. Stock option awards under both plans generally vest over a period of four years with 25% vesting on the one year anniversary of the award and the remainder vesting monthly over the next 12 quarters of the grantee’s service to the Company as an employee or an advisor/consultant. During the fiscal years ended September 30, 2023 and 2022, 65,098 and 684,673 options were granted under the 2017 Plan, respectively.

Commitments and Contingencies Disclosure [Abstract]
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 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 in the middle 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. The Company has 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.

Income Taxes	Income Taxes The components of loss before income tax expense were as follows: Fiscal Year Ended September 30, 2023 2022 (in thousands) Domestic $ (23,170) $ (11,211) Foreign (28,656) (36,211) Loss before income tax expense $ (51,826) $ (47,422) The components of the provision for income taxes were as follows: Fiscal Year Ended September 30, 2023 2022 (in thousands) Current Federal $ — $ — State 10 13 Foreign 21 68 $ 31 $ 81 Deferred Federal $ — $ — State — — Foreign — — $ — $ — Income tax expense $ 31 $ 81 The effective tax rate differs from the federal statutory income tax rate applied to the loss before income tax expense due to the following: Fiscal Year Ended September 30, 2023 2022 Tax computed at federal statutory rate 21.00 % 21.00 % State income tax—net of federal benefit (0.02) % (0.02) % Foreign rate differential (11.62) % (16.05) % Change in valuation allowance (6.23) % 0.09 % Stock-based compensation — % — % Research and development tax credit — % — % Other (0.05) % (0.04) % Return to provision (0.46) % 0.01 % Transaction costs — % 1.58 % Deferred adjustment true up (0.64) % (6.74) % Income tax expense 1.98 % (0.17) % Significant components of the Company’s deferred tax assets are as follows: As of September 30, 2023 2022 (in thousands) Deferred tax assets: Net operating losses $ 75,566 $ 64,013 Tax credit carryforwards 4,183 4,183 Allowances and reserves 101 36 Deferred revenue 535 473 Depreciation 37 17 Amortization of intangible assets 2,243 3,067 Disallowed interest 38 — Accrued payroll 627 619 Right-of-use assets 7 9 Other 54 29 Unrealized loss (254) (567) Less: valuation allowance (83,137) (71,879) Total deferred tax assets $ — $ — In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income and tax planning strategies in making this assessment. Following this assessment, management believes it is more likely than not that the deferred tax assets will not be realized; accordingly, the Company has recorded a full valuation allowance as of September 30, 2023 and 2022. The following table presents a roll forward of the valuation allowance for the fiscal years ended September 30, 2023 and 2022: Fiscal Year Ended September 30, 2023 2022 (in thousands) Beginning balance $ (71,879) $ (70,573) Additions (898) (8,643) Deductions (reversal) (10,360) 7,337 Ending balance $ (83,137) $ (71,879) On the basis of this evaluation, as of September 30, 2023, a valuation allowance of $83.1 million has been recorded to recognize only the portion of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as the Company’s projections for growth. At September 30, 2023 and 2022, the Company had federal net operating loss carryforwards of approximately $201.5 million and $184.7 million, respectively and state net operating loss carryforwards of $144.5 million and $141.4, respectively. The federal and state loss carryforwards begin to expire in 2030, unless previously utilized. As of September 30, 2023 and 2022, the Company also had federal research and development tax credit carry-forwards of approximately $2.2 million for both years, and state research and development tax credit carry-forwards of approximately $1.9 million for both years. The federal research and development tax credits will begin to expire in 2032. The state research and development tax credits have an indefinite life and do not expire. At September 30, 2023 and 2022, the Company had foreign net operating loss carryforwards of approximately $99.0 million and $39.7 million, respectively. The foreign net operating loss carryforward will begin to expire in 2023. Utilization of the federal and state net operating loss carryforwards may be subject to substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups. Any uncertain tax positions would be related to tax years that remain open and subject to examination by the relevant tax authorities. The Company has not accrued for interest or penalties associated with unrecognized tax liabilities. The Company is subject to U.S. federal tax authority examinations and U.S. state tax authority examinations for all years due to the net operating loss carryforwards. The Company files a federal U.S. tax return and several U.S. state income tax returns with varying statues of limitations. On August 16, 2022, the U.S. government enacted the Inflation Reduction Act (“IRA”), which, among other things, implements a 15% corporate alternative minimum tax based on the adjusted financial statement income for certain large corporations and a 1% excise tax on net share repurchases. The minimum tax and the excise tax, if applicable, are effective for fiscal years beginning after December 31, 2022. We do not expect the IRA to have a material impact on our financial position, results of operations or cash flows for the foreseeable future. We will continue to monitor additional guidance from the Internal Revenue Service.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Restructuring Activities 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 includes a reduction of the Company's workforce by approximately 84 people, or approximately 28%. The Company expects the plan will result in (i) restructuring charges consisting of approximately $3.1 million in employee severance and notice period payments, benefits, and related costs and $0.1 million in non-cash stock-based compensation expense related to vesting of share-based awards, and (ii) cash expenditures of approximately $0.8 million to satisfy amounts owed due to earned vacation time. As part of the plan, the Company will focus its attention on its core MariaDB Enterprise Server database product. Products not related to the core MariaDB Enterprise Server business, including SkySQL and Xpand, will no longer be sold and the Company has implemented a plan to help existing customers migrate off these products. The Company expects the majority of the restructuring charges and expenses to be incurred during the first half of fiscal year 2024. In addition, an estimated 13 employees are expected to be provided transition packages that will provide for continued services through various dates of the Company’s fiscal year 2024. SkySQL Divestiture 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. New Debt and Related-Party Transaction On October 10, 2023, the Company issued a senior secured promissory note to RP Ventures LLC (“RP Ventures”), a Delaware limited liability company, in the principal amount of $26.5 million (the “Note”). RP Ventures acts as Agent under the Note. The Note will mature on the earlier of (i) January 10, 2024, (ii) the occurrence of a "change of control" (as that term is defined in the 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 Note is otherwise declared due and payable pursuant to its terms. The proceeds of the Note were used by the Company to repay all amounts outstanding under the Term Loan (repaid on October 11, 2023), and have been and are being used to pay certain Note-related expenses, including expenses of RP Ventures, and for working capital purposes as approved by the Company’s board of directors. The Company paid RP Ventures a nonrefundable funding fee of $132,500, and agreed to pay or reimburse RP Ventures and Runa Capital Fund II, L.P. (“Runa”) for its out-of-pocket expenses related to the Note transaction. Net proceeds from the Note were $7.7 million after repayment of the Term Loan and the expenses set forth above. Interest on the Note accrues on the principal amount at the rate of ten percent (10%) per annum and will be paid on a quarterly basis commencing on January 1, 2024. The Company may prepay any amounts due under the Note without penalty or premium, subject to the prior written consent of RP Ventures, provided that any prepayment of principal under the Note be accompanied by interest accrued and unpaid through the date of such prepayment. RP Ventures may demand immediate repayment of certain amounts outstanding under the Note if the Company or any of its subsidiaries incurs additional indebtedness or disposes, sells, or otherwise transfers any of their property or assets outside of the ordinary course of business, or if the Company or any of its subsidiaries receives any proceeds from the occurrence of a casualty event. Until January 10, 2024, 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 RP Ventures or Runa. The Note also 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’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. In connection with issuance of the Note, the Company and MariaDB USA. Inc. and certain other of the Company’s subsidiaries (the “Guarantors”) entered into a Guarantee and Collateral Agreement (the “Security Agreement”), pursuant to which the Company and each Guarantor pledged substantially all of their respective assets as collateral for the Note and each Guarantor guaranteed to RP Ventures the payment of all obligations arising from the Note. P ursuant to the terms of the Note, on October 10, 2023, Michael Fanfant and Yakov “Jack” Zubarev were appointed to the Company’s board of directors. Mr. Fanfant is the sole member and manager of RP Ventures, and is a shareholder of Runa Capital II (GP), the general partner of Runa, 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 approximately 8% of the outstanding Ordinary Shares of the Company. Mr. Zubarev is the brother of Ilya Zubarev, who is a shareholder in Runa Capital II (GP) and Runa Capital Opportunity I (GP) and one of four members of the investment committee of each of these entities that makes all investment and voting decisions relating to the Company’s Ordinary Shares held by Runa, Runa Capital Opportunity Fund I, L.P. and Runa Ventures I Limited.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying 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.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make judgements, estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such estimates include but are not limited to legal contingencies, expected period of benefit for deferred commissions, fair value measurement of financial instruments, allowances for credit losses, fair value of acquired intangible assets and goodwill, impairment analysis for goodwill and intangibles assets, useful lives of acquired intangible assets and property and equipment, stock-based compensation and accounting for income taxes. The Company based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Since future events and their effects cannot be predicted with absolute certainty, actual results could differ from current estimates.
Revenue Recognition	Revenue Recognition The Company derives revenues from subscriptions that require customers to pay a fee in order to access the Company’s database solutions. Contract periods with customers generally are one year with occasional contracts ranging up to three years. The Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, the Company satisfies a performance obligation. At the inception of a customer contract, the Company makes an assessment as to that customer's ability to pay for the services provided. The Company assesses collectability based on several factors, including credit worthiness of the customer along with past transaction history. In addition, the Company performs periodic evaluations of its customers’ financial condition. Most of the Company’s revenue contracts are subscription based and contain a single performance obligation. The subscription contracts typically do not offer to the customers any future rights that would constitute material rights. Contract prices are generally composed of fixed consideration for a specific period of time as the Company in general does not offer refunds, rebates, customer loyalty programs or other forms of customer incentive payments. As the Company's cloud-oriented subscription services are delivered to customers electronically and over time, revenue is generally recognized ratably over the contract terms. Historically, no significant judgment has generally been required in determining the amount and timing of revenue from the Company’s contracts with customers. Contract modifications happen when there is an upsell, where the customers subsequently enter into contract with the Company to purchase additional product offerings. Contract modifications related to upsells are accounted for prospectively. 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 September 30, 2023 and 2022, the balance of deferred revenue was $46.6 million and $31.6 million, respectively, which includes $12.4 million and $0 of refundable customer deposits, respectively. Revenue recognized during the fiscal years ended September 30, 2023 and 2022 that was included in the deferred revenue beginning balance of each year was $20.3 million and $25.5 million, respectively. Incremental direct costs of obtaining a contract, which consist of sales commissions primarily for new business and upsells, are deferred and amortized over the estimated life of the customer relationship if renewals are expected and the renewal commission is not commensurate with the initial commission. The Company elected the practical expedient to expense commissions on renewals where the specific anticipated contract term amortization period is one year or less. The Company amortizes the capitalized commission cost as a selling expense on a straight-line basis over a period of five years. The Company classifies deferred commissions as current or noncurrent based on the timing of when it expects to recognize the expense. The current and noncurrent portions of deferred commissions are included in prepaid and other current assets and other noncurrent assets, respectively, in its consolidated balance sheets. The current and noncurrent deferred commissions had a balance of $5.6 million and $4.6 million as of September 30, 2023 and 2022, respectively. Service revenue is related to the provisioning of support to customers. The service revenue is recognized as earned. Cost of Revenue Cost of subscription revenue consists of expenses for providing our database products and services to our customers. These expenses include third-party cloud infrastructure costs, network and bandwidth costs, credit card processing fees, and revenue share associated with selling third-party software tools.
Foreign Currency Translation and Re-measurement	Foreign Currency Translation and Re-measurement The functional currency of the Company is the Euro (EUR). The functional currency of the Company’s international subsidiaries is either the EUR or the local currency in which the international subsidiary operates. For the foreign subsidiaries where the functional currency is not the local currency, local currency denominated monetary assets and liabilities are re-measured into the functional currency at current exchange rates and foreign currency denominated nonmonetary assets and liabilities are re-measured into the functional currency at historical exchange rates. Transaction gains or losses from foreign currency re-measurement and settlements are included in other expense, net in the consolidated statements of operations and comprehensive loss. The Company’s reporting currency is the U.S. dollar. In the consolidated financial statements, the financial information of the Company and its international subsidiaries have been translated into U.S. dollars. The Company uses the exchange rate as of each balance sheet date to translate assets and liabilities and the average exchange rate during the period to translate revenue and expenses into U.S. dollars. Stockholders’ deficit is translated at historical rate. Translation gains or losses resulting from translating foreign functional currency financial statements into U.S. dollars are included in accumulated other comprehensive loss as a component of stockholders’ deficit. The Company is exposed to fluctuations between the U.S. dollar and the EUR. The change in the value of the EUR relative to the U.S. dollar may affect the Company’s financial results reported in the U.S. dollar terms without giving effect to any underlying changes in its business or results of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash held in our bank accounts as well as highly liquid investments with an original maturity of three months or less at acquisition. The Company maintains such investments in immaterial money market funds, which have readily determinable fair values using quoted prices in active markets.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents and accounts receivable. Substantially all of the Company’s cash and cash equivalents are maintained at financial institutions in the United States and Finland. Cash and cash equivalents can exceed amounts insured by the Federal Deposit Insurance Corporation and Deposit Guarantee schemes of up to $250,000 and €100,000, respectively. The Company’s accounts receivable are derived from revenue earned from customers located in the U.S. and internationally. Customer credit risk is managed by the business and is subject to the Company’s established policy and procedures relating to customer credit risk management. The credit quality of a customer is assessed based on an extensive credit rating scorecard and individual credit limits are defined in accordance with this assessment. Outstanding customer receivables and contract assets are regularly monitored. The Company evaluates the concentration of risk with respect to trade receivables as low, as its customers are in several geographical regions and industries and operate in largely independent markets.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, as described below, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices for identical or similar assets and liabilities in markets that are not active or observable inputs other than quoted prices in active markets for identical or similar assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These include the Black-Scholes option-pricing model which uses inputs such as expected volatility, risk-free interest rate and expected term to determine fair market valuation. As of September 30, 2022, the Company’s investment securities consisted of $26.0 million in United States (“U.S.”) Treasury Bills, all of which matured by December 31, 2022. During the fiscal year ended September 30, 2022, the Company changed the classification of its U.S. Treasury Bills from held-to-maturity to available-for-sale based on its intent to sell the securities. The Company’s available-for-sale marketable securities are recorded at fair value. Any unrealized gains or losses are recorded in accumulated other comprehensive loss within the consolidated balance sheets. Any realized gains and losses are recorded as a part of other income (expense), net in the consolidated statements of operations and comprehensive loss in accordance with ASC 320 “Investments – Debt and Equity Security.” The total proceeds received from disposal of available-for-sale securities during the fiscal year ended September 30, 2023 and 2022 was $25.9 million and $9.4 million, respectively. The total realized gain during the fiscal year ended September 30, 2023 and 2022 was $0.9 million and $0.1 million, respectively. The Company considers all investments with original maturities of greater than three months and less than 12 months to be short-term investments. There were no available-for-sale-securities outstanding as of September 30, 2023. The fair value of available-for-sale securities outstanding as of September 30, 2022 was as follows (in thousands): Amortized Gross Gross Effect of Fair Value U.S. Treasury Bills $ 25,962 $ 2,177 $ — $ (2,140) $ 25,999 Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification at each reporting date. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the years presented. As of September 30, 2023 and 2022, 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, deferred revenue) approximate fair value due to the short-term nature of such items. The money market funds within cash equivalents and available-for-sale securities are classified within Level 1 of the hierarchy as the values are derived from quoted prices in active markets. The Company’s warrants are recorded at fair value on a recurring basis. The estimation of fair value for these investments requires the use of significant unobservable inputs, and these inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. As a result, the Company classifies the Public Warrants (as defined in Note 7) as level 1, the Private Warrants (as defined in Note 7) as level 2, and the Kreos Rollover Warrants (as defined in Note 7) as level 3, within the fair value hierarchy. Refer to Note 7 Warrants for further details on the valuation inputs. We have not elected the fair value option as prescribed by ASC 825, The Fair Value Option for Financial Assets and Financial Liabilities, for our financial assets and liabilities that are not otherwise required to be carried at fair value. Under ASC 820, Fair Value Measurements and Disclosures, material financial assets and liabilities not carried at fair value, such as our long-term debt and accounts receivable and payable, are reported at their carrying values.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivable is recognized if and when an amount of consideration is due from a customer and is unconditional (i.e., only the passage of time is required before payment of the consideration is due). Accounts receivable are non-interest bearing and are generally on terms of 30 to 60 days. Generally, trade receivables are written-off if past due for more than 180 days and are not subject to enforcement activity. Accounts receivable presented on the consolidated balance sheets are adjusted for any write-offs and net of allowance for credit losses. An analysis is performed at each reporting date using a provision matrix and customer specific data to measure expected credit losses. The Company applies a simplified approach in calculating current expected credit losses ("CECL"). Therefore, the Company does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime CECLs at each reporting date. The Company has established a provision matrix that is based on the Company’s historical observed default rates. The Company will calibrate the historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment. The Company’s estimates of the allowance for credit losses may not be indicative of the Company’s actual credit losses requiring additional charges to be incurred to reflect the actual amount collected.
Prepaids and Other Current Assets	Prepaids and Other Current Assets Prepaid expenses and other current assets totaled $5.8 million and $15.5 million as of September 30, 2023 and 2022, respectively.
Warrant Liabilities	Warrant Liabilities As discussed in Note 7 Warrants, the Legacy MariaDB preferred share warrants were either settled or converted into Ordinary Share warrants through the Business Combination (referred to as the “Legacy MariaDB Warrants”). Further, as discussed in Note 7 Warrants, the Company assumed Private Warrants and Public Warrants th rough the Business Combination. The Company accounts for its warrants in accordance with the guidance contained in ASC 815-40. Such guidance provides that because these warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a derivative liability. The warrants are measured at fair value on a recurring basis. The Company estimates the fair value of the Legacy MariaDB Warrants using the Black-Scholes option pricing model and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, as well as assumptions for expected volatility, expected life, yield, and risk-free interest rate. The Company estimates the fair value of th e Public Warrants based on the observable market quote in an active market under the ticker MRDB.WS. As the transfer of Private Warrants to anyone outside of a small group of individuals who are permitted transferees would result in the Private Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Warrant is equivalent to that of each Public Warrant, with an insignificant adjustment for short-term marketability restrictions. The Company continues to adjust the liability for changes in fair value until the earlier of the exercise of the warrants, the expiration of the warrants, or until such time as the warrants are no longer considered a liability.
Segment Information	Segment Information Operating segments are based upon the Company’s internal organizational structure, the manner in which its operations are managed, the criteria used by its Chief Operating Decision Maker (“CODM”) to evaluate segment performance and the availability of separate financial information to be regularly reviewed for resource allocation and performance assessment. The Company has determined its CODM to be the Chief Executive Officer (“CEO”). The CEO reviews financial information presented on a consolidated basis for purposes of managing the business, allocating resources, making operating decisions and assessing financial performance. On this basis, the Company is organized and operates as a single segment within the Software-as-a-Service ("SaaS") space. As of September 30, 2023, the Company has a single operating and reportable segment.
Stock-Based Compensation	Stock-Based Compensation Employees (including senior executives) and directors of the Company have been granted share-based payments in the form of stock options and restricted stock unit awards (the "RSUs"). Stock-based compensation costs related to stock options are calculated based on the fair value of the share-based award on the date of grant using the Black-Scholes option-pricing model and stock-based compensation costs for RSUs are calculated based on the fair value using the closing price of the Company's Ordinary Shares on the date of grant. Stock-based compensation costs are recognized as compensation expense in the accompanying consolidated statement of operations and comprehensive loss on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related input assumptions requires judgment, including estimating the fair value of Ordinary Shares, share price volatility, and expected term, which impact the fair value estimated and the expense that will be recognized. Legacy MariaDB granted options to its employees, members of the board as well as some advisors under the following plans, collectively (the “Legacy Plans”): • Summer 2022 USA Share Option Plan • Global Share Option Plan 2017 • Global Share Option Plan 2017 USA • Global Share Option Plan 2014 Europe • Global Share Option Plan 2014 USA • Global Share Option Plan 2012 Europe • Global Share Option Plan 2012 USA • Global Share Option Plan 2012 France • Global Share Option Plan 2010 Europe • Global Share Option Plan 2010 USA • Global Share Option Plan 2010 France In connection with the Business Combination, each equity award issued and outstanding under the Legacy Plans listed above (each, a "Legacy MariaDB Equity Award") was automatically converted into an equity award to be settled in MariaDB plc Ordinary Shares generally on the same terms and conditions as were applicable to such Legacy MariaDB Equity Award immediately prior to the Business Combination (other than adjustments to the number of shares and exercise price based on the Exchange Ratio). As of September 30, 2023 , stock options and RSUs are the o nly types of share-based payment that have been granted under the Company’s plans.
Computation of Loss Per Share	Computation of Loss Per Share
Research and Development	Research and Development Costs incurred in research and development, which includes software engineering expenses, such as salaries and related benefits, stock-based compensation, depreciation, professional services and overhead expenses related to the general development of the Company’s products, are expensed as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. The Company has not capitalized any software development costs since the period between establishing technological feasibility and general customer release is relatively short and as such, these costs have not been material.
Comprehensive Loss	Comprehensive Loss Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, including foreign currency translation adjustments and unrealized gains and losses on marketable securities. Other comprehensive loss, net of tax, is presented on the Consolidated Statements of Operations and Comprehensive Loss.
Leases	Leases The Company leases office space, domestically and internationally, under operating leases. The Company’s leases have remaining lease terms of less than one year. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheets. The Company does not have any finance leases. The Company determines if an arrangement is a lease, or contains a lease, at inception. The Company assesses all relevant facts and circumstances in making the determination of the existence of a lease. For leases with terms greater than 12 months, the Company records the related asset and obligation at the present value of lease payments over the term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments, and uses the implicit rate when readily determinable. Many of the Company’s leases include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the Company does not separate non-lease components from lease components. Operating lease costs are included in research and development and selling, general and administrative costs on the statement of operations.
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination. Goodwill is not subject to amortization, but is subject to at least an annual assessment for impairment. The Company performs its impairment analysis of goodwill on an annual basis during the fourth quarter of the fiscal year unless conditions arise that warrant a more frequent evaluation. When goodwill is assessed for impairment, the Company has the option to perform an assessment of qualitative factors of impairment (optional assessment) prior to necessitating a quantitative impairment test. Should the optional assessment be used for any given year, qualitative factors to consider for a reporting unit include: cost factors; financial performance; legal, regulatory, contractual, political, business, or other factors; entity specific factors; industry and market considerations; macroeconomic conditions; and other relevant events and factors affecting the reporting unit. If the Company determines in the qualitative assessment that it is more likely than not that the fair value of the reporting unit is less than its carrying value, a quantitative test is then performed. Otherwise, no further testing is required. For a reporting unit tested using a quantitative approach, the Company compares the fair value of the reporting unit with the carrying amount of the reporting unit, including goodwill. The fair value of the reporting unit is estimated using an income approach. Under the income approach, the Company measures fair value of the reporting unit based on a projected cash flow method using a discount rate determined by its management which is commensurate with the risk inherent in its current business model. The Company’s discounted cash flow projections are based on its annual financial forecasts developed internally by management for use in managing its business. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, then the amount of goodwill impairment will be the amount by which the reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.
Intangible Assets	Intangible Assets Intangible assets are comprised of acquired technology, trademarks and contractual relationships. Identifiable intangible assets resulting from the acquisitions of entities accounted for using the purchase method of accounting are estimated by management based on the fair value of assets received. Identifiable definite-lived intangible assets are being amortized over the period of estimated benefit using the straight-line method and estimated useful lives of 3 to 8 years.
Business Combinations	Business Combinations The Company applies the provisions of ASC 805, Business Combinations, in accounting for its acquisitions. To determine whether transactions should be accounted for as asset acquisition or business combination, the Company evaluates whether substantially all of the fair value of gross assets included in a transaction is concentrated in a single asset (or a group of similar assets), resulting in an asset acquisition; if that is not the case, the resulting accounting is as a business combination. In an asset acquisition, the cost of acquiring the asset group, including transaction costs, is allocated to the acquired assets or assumed liabilities based on their relative fair values without giving rise to goodwill. In a business combination, the Company recognizes separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as any contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to its consolidated statements of operations.
Property and Equipment	Property and Equipment Property and equipment include computer software, computer equipment, leasehold improvements and furniture and fixtures. Computer software, computer equipment and furniture and fixtures are stated at cost and generally depreciated on a straight-line basis over an estimated useful life of three years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the remaining terms of the leases. Upon disposal, assets and related accumulated depreciation are removed from the accounts and the related gain or loss is included in the results from operations.
Income Taxes	Income Taxes Income taxes are accounted for using an asset and liability approach, which requires the recognition of deferred tax assets and liabilities for expected future tax events that have been recognized differently on the Company’s consolidated financial statements and tax returns. The measurement of current and deferred tax assets and liabilities is based on provisions of the enacted tax law and the effects of future changes in tax laws or rates are not anticipated. A valuation allowance is established when necessary to reduce deferred tax assets to amounts expected to be realized based on available evidence. In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. As a result, the Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in its tax return. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. The Company maintains a full valuation allowance against all of its net US federal and state deferred tax assets. The Company assessed whether a valuation allowance should be established against its deferred tax assets based on consideration of all available evidence, using a “more likely than not” standard. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence related to the likelihood of

Recent Accounting Updates	Recent Accounting Updates Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASU”). ASU’s not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial statements. Recently Adopted Accounting Updates In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” This guidance, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. ASU 2019-12 is effective for public business entities in fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this standard on October 1, 2022. The adoption of this standard did not have a material impact on the consolidated financial statements.
