Summary of Business and Significant Accounting Policies | 1. Summary of Business and Significant Accounting Policies Marin Software Incorporated (the “Company”) was incorporated in Delaware, United States of America (“U.S.”) in March 2006. The Company provides enterprise marketing software for advertisers and agencies to integrate, align and amplify their digital advertising spend across the web and mobile devices. Offered as a unified software-as-a-service (“SaaS”) advertising management solution for search, social and eCommerce advertising, the Company’s platform helps digital marketers convert precise audiences, improve financial performance and make better decisions. Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements and condensed footnotes have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles in the U.S. (“GAAP”) for complete financial statements. In the opinion of management, all adjustments, consisting of only normal recurring items, considered necessary for fair statement have been included. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, or for other interim periods or future years. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of December 31, 2023 is derived from audited financial statements as of that date but does not include all of the information and footnotes required by GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 , filed with the Securities and Exchange Commission (“SEC”) on February 23, 2024. Reverse Stock Split and Reduction in Authorized Shares On April 12, 2024, the Company effected a reverse stock split of its outstanding common stock and a reduction in the Company's authorized shares of common stock. As a result of the reverse stock split, each six outstanding shares of the Company’s common stock were combined into one outstanding share of common stock, without any change in par value. The common stock began trading on the Nasdaq Capital Market on a split-adjusted basis on April 15, 2024. No fractional shares were issued in connection with the reverse stock split as the Company paid the fair value of such fractional shares in cash. As a result of the reduction in the Company's authorized shares of common stock, the Company's authorized shares went from 142,857 shares to 47,619 shares. All share and per share amounts of the Company’s common stock, as well as stock options and restricted stock units (“RSUs”), included in the accompanying condensed consolidated financial statements have been retroactively adjusted to give effect to the reverse stock split for all periods presented, unless indicated otherwise. In addition, as a result of the reverse stock split, the Company reclassified an amount equal to the reduction in the par value of common stock to additional paid-in capital on its condensed consolidated balance sheets. Liquidity and Going Concern The Company has incurred significant losses in each fiscal year since its incorporation in 2006. The Company incurred a net loss of $ 4,429 for the six months ended June 30, 2024 and a net loss of $ 21,917 for the year ended December 31, 2023. As of June 30, 2024, the Company had cash and cash equivalents of $ 7,942 and an accumulated deficit of $ 348,680 . Historically, the Company has relied primarily on the sale of its capital stock to fund operating activities. Management expects to incur additional losses and experience negative operating cash flows into the foreseeable future. In July 2023, the Company commenced a restructuring plan that included a global reduction-in-force and other cost saving actions to reduce its expenses (the “2023 Restructuring Plan” ). The 2023 Restructuring Plan resulted in the reduction of the Company's global employees by 64 full-time employees during the second half of 2023, reducing its total headcount by approximately 37%. The 2023 Restructuring Plan was substantially complete in 2023 . The Company’s ability to achieve its business objectives, and to continue to meet its obligations, is dependent upon maintaining a certain level of liquidity, which is impacted by several factors, such as its ability to manage its cash flows, including the effectiveness of the 2023 Restructuring Plan, its ability to maintain its strategic partnerships, its ability to increase new bookings, the extent of customer acceptance, retention and use of its MarinOne platform, and general macroeconomic conditions such as inflation or the extent and duration of any recession. Although the Company has pursued, and may continue to pursue, additional sources of liquidity, including additional equity and debt financing, there is no assurance that any additional financing will be available on acceptable terms, or at all. Failure to manage its cash flows, increase new bookings, improve customer retention rates, or raise additional capital would have a material adverse effect on the Company’s ability to achieve its intended business objectives. Based on the funds the Company has available as of the date of the filing of this Quarterly Report on Form 10-Q and its history of recurring losses and negative operating cash flows, there is substantial doubt raised about the Company’s ability to continue as a going concern. The Company’s ability to continue as a going concern is substantially dependent upon its ability to achieve its intended business objectives. If the Company is unable to achieve its intended business objectives, it is probable that the Company may be required to initiate further cost savings activities, extend payment terms with suppliers, liquidate assets where possible, or wind-up operations. These actions could materially impact the Company’s business, results of operations and future prospects. Therefore, there is substantial doubt about the Company’s ability to continue as a going concern for one year after the filing date of the accompanying condensed consolidated financial statements. Due to the fact that the Company has not yet been able to obtain sufficient funding to sustain operations or realize a net positive cash flow, the Company’s management and board of directors have determined that it is in the best interests of the Company’s stockholders to seek strategic alternatives. As part of this process, the Company is considering a wide range of options with a focus on maximizing stockholder value, including a potential sale of the Company, a merger, a sale of assets of the Company, or other strategic transaction. The Company has engaged an investment banker to act as its financial advisor in connection with this review. There can be no assurance that this process will result in the Company pursuing any particular transaction or other strategic outcome or as to the terms or timing of any potential transaction. The Company is currently engaged in preliminary discussions with a small number of private companies and other counterparties regarding potential “reverse merger” and “take-private” transactions. Any such completed transaction would have a dramatic impact on Marin stockholders. Given the preliminary stage of such discussions, at this time there is no way to quantify the potential impact of a transaction, if any. For any such potential transaction to progress, substantial due diligence by all involved parties would be need to be conducted, as well as agreement of transaction terms, negotiation and approval of transaction documents and the satisfaction of applicable closing conditions. Any such process would be time-consuming and expensive and there can be no assurance that any of the above potential transactions or any other transaction will ultimately be successful. If the Company is unable to complete a satisfactory transaction soon, it will be necessary to seek additional financing or pursue a dissolution and liquidation in the near future, where holders of the Company’s common stock may receive little or no recovery for their shares of common stock. Even if the Company does complete a satisfactory strategic transaction, the Company’s stockholders may not recognize any return on their investment in shares of our common stock. In parallel, the Company is also preparing for a potential statutory dissolution under the Delaware General Corporate Law and liquidation in the event the Company cannot raise additional capital or complete a strategic transaction in the near future, and the Company has engaged advisors to help us prepare for a potential dissolution and liquidation. The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the Company’s uncertainty related to its ability to continue as a going concern. These adjustments could materially impact the Company’s accompanying condensed consolidated financial statements. The Company is not aware of any specific event or circumstance that would require it to update its estimates, judgments or revise the carrying value of its assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements. Fair Value of Financial Instruments The Company’s financial instruments, including accounts receivable, accounts payable and accrued expenses are carried at cost, which approximates fair value because of the short-term nature of those instruments. Cash equivalents are comprised of money market funds recorded at fair value and are classified as Level 1 within the fair value hierarchy. Allowances for Credit Losses and Revenue Credits The Company performs a regular review of its customers’ payment histories and associated credit risks and it generally does not require collateral from its customers. Certain contracts with advertising agencies contain sequential liability provisions, whereby the agency does not have an obligation to pay the Company until payment is received from the agency’s customers. In these circumstances, the Company evaluates the credit worthiness of the agency’s customers, in addition to the agency itself. The Company maintains an allowance for credit losses which reflects its best estimate of potentially uncollectible trade receivables and is based on both specific and general reserves. General reserves are maintained on a collective basis by considering factors such as historical experience, the age of the receivable balances, current economic conditions and a reasonable and supportable forecast of future economic conditions. The activity in the Company’s allowance for credit losses for the six months ended June 30, 2024 is summarized as follows (in thousands): Total Balance at December 31, 2023 $ 501 Current period provision for expected losses ( 13 ) Write-offs charged against allowance ( 82 ) Balance at June 30, 2024 $ 406 From time to time, the Company provides credits to customers that typically relate to customer disputes or billing adjustments and are recorded as a reduction of revenue. Reserves for these revenue credits are accounted for as variable consideration under authoritative revenue recognition guidance (see Note 2) and are estimated based on historical credit activity. As of June 30, 2024 and December 31, 2023, the Company recorded an allowance for potential customer credits in the amount of $ 16 and $ 12 , respectively. Revenue Recognition The Company generates revenue principally from subscriptions either directly with advertisers or with advertising agencies to its platform for the management of search, social and eCommerce. The Company also generates revenue from strategic agreements with certain leading publishers. Under the subscription agreements, the Company receives consideration based on the advertising spend that customers manage on its platform. Revenue is recognized when control of these services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. See Note 2 for further discussion of the Company’s revenue. Internally Developed Software Costs incurred in the development phase are capitalized and amortized over the product’s estimated useful life, when the development costs are considered recoverable. The Company expenses all costs incurred that relate to planning and post implementation phases of development. Development phase costs generally include salaries and personnel costs and third-party contractor expenses associated with software development, configuration and coding. Capitalized costs related to internally developed software under development are treated as construction in progress until the program, feature or functionality is ready for its intended use, at which time amortization commences. During the six months ended June 30, 2024, the Company analyzed whether its internally developed software still met the definition of an asset, and concluded that due to the fact that the internally developed software does not have a future economic benefit to the Company, based on its negative cash flows, the internally developed software no longer meets the definition of an asset. Additionally, as the internally developed software no longer meets the definition of an asset, the development costs related to internally developed software will no longer be capitalized as these development costs are considered to be unrecoverable. Instead, all development costs related to the internally developed software will be expensed as incurred. As of June 30, 2024 and December 31, 2023, there was no unamortized internally developed software costs, including construction in progress. During the three and six months ended June 30, 2024 , no amounts were capitalized or amortized relating to internally developed software as the development costs related to internally developed software in the period were considered unrecoverable. During the three and six months ended June 30, 2023 , the Company capitalized $ 578 and $ 1,157 , respectively, of development costs related to internally developed software and amortized $ 426 and $ 845 , respectively, related to internally developed software. Amortization of internally developed software is reflected in cost of revenue. Costs associated with minor enhancements and maintenance are expensed as incurred. Research and Development Research and development costs are expensed as incurred, except for certain internal software development costs, which may be capitalized when recoverable, as noted above. Research and development costs consist of personnel costs, including salaries, stock-based compensation expense, benefits and bonuses, as well as no n-personnel costs such as professional fees payable to third-party development resources, amortization of intangible assets and allocated overhead costs.
