Business Overview and Basis of Presentation	Business Overview and Basis of Presentation Marqeta, Inc. (“the Company”) was incorporated in the state of Delaware in 2010 and creates digital payment technology for innovation leaders. The Company's modern card issuing platform empowers its customers to create customized and innovative payment card programs, giving them the configurability and flexibility to build better payment experiences. The Company provides all of its customers issuer processor services and for most of its customers it also acts as a card program manager. The Company primarily earns revenue from processing card transactions for its customers. Basis of Presentation The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission, (“SEC”), for interim reporting. Certain information and note disclosures included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The Condensed Consolidated Balance Sheet as of December 31, 2025 has been derived from the Company’s audited consolidated financial statements, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which was filed with the SEC on February 24, 2026. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto included in the Annual Report on Form 10-K. The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the accompanying Condensed Consolidated Financial Statements reflect all adjustments of a normal, recurring nature considered necessary for a fair presentation of the Company's consolidated financial position, results of operations, comprehensive income (loss), and cash flows for the interim periods presented. The interim results for the three and six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026, or for any other future annual or interim period. Reverse Stock Split On June 30, 2026, following approval by the Company’s stockholders at the 2026 Annual Meeting of Stockholders on June 10, 2026, the Company effected a one-for-four reverse stock split of its issued and outstanding shares of Class A common stock and Class B common stock, together with a proportional reduction in the number of authorized shares of Class A, Class B, and preferred stock (the “Reverse Stock Split”). The Reverse Stock Split was effected by filing a Certificate of Amendment to the Company’s Amended and Restated Certificate of Incorporation. As a result of the Reverse Stock Split, every four shares of the Company’s Class A common stock or Class B common stock were automatically combined and converted into one share of the respective class of stock. The Reverse Stock Split did not change the par value per share of the Company’s common or preferred stock, nor did it alter the relative rights, preferences, or privileges of the holders of such stock. As a result, the aggregate par value of outstanding common stock was reduced proportionately, with a corresponding increase to additional paid-in capital. Total stockholders’ equity remained unchanged. No fractional shares were issued in connection with the Reverse Stock Split, and stockholders who otherwise would have been entitled to a fractional share received cash in lieu thereof. All share-related and per share information presented in the accompanying condensed consolidated financial statements and notes thereto has been retroactively adjusted to reflect the Reverse Stock Split for all periods presented, as if the split had occurred at the beginning of the earliest period presented. Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make various estimates and assumptions relating to reported amounts of assets and liabilities, disclosure of contingent liabilities, and reported amounts of revenue and expenses. Significant estimates and assumptions include, but are not limited to, the fair value and useful lives of assets acquired and liabilities assumed through business combinations, the estimation of contingent liabilities, the fair value of equity awards and warrants, share-based compensation, the estimation of variable consideration in contracts with customers, the cumulative network incentive rate the Company expects to earn during the annual measurement period, and valuation of income taxes. Actual results could differ materially from these estimates. Business Risks and Uncertainties Prior to the quarter ended March 31, 2026, the Company incurred net losses in each quarter since its inception, with the exception of the quarter ended June 30, 2024, which was primarily due to the forfeiture of the Executive Chairman Long-Term Incentive Award. As of June 30, 2026, the Company had an accumulated deficit of $796.4 million. The Company believes that its cash and cash equivalents of $691.4 million and short-term investments of $9.5 million as of June 30, 2026 are sufficient to fund its operations through at least the next twelve months from the issuance of these financial statements.
