Description of Business and Basis of Presentation | Description of business and basis of presentation Organization and description of business—Alamar Biosciences, Inc. (the “Company”) was incorporated in the State of Delaware on May 7, 2018, and is based in Fremont, California. The Company develops a highly sensitive proteomic liquid biopsy platform and sells instruments, consumables and services based on this platform to enable early detection of diseases. As of March 31, 2026, the Company has wholly-owned subsidiaries in Asia, Europe and North America. Reverse stock split—On April 8, 2026, the Company’s stockholders and board of directors approved an amendment to the Company’s certificate of incorporation to effect a reverse split of shares of the Company’s Class A and Class B common stock (collectively "Common Stock") and Founders Preferred Stock on a one-for-2.418 basis, which was effected on April 10, 2026 (the “Reverse Stock Split”). The number of authorized shares and the par values of the Common Stock and Series A-1, Series A-2, Series A-3, Series A-4, Series B, Series B-Plus and Series C convertible preferred stock ("Preferred Stock") and Founders Preferred Stock (collectively with Preferred Stock "Convertible Preferred Stock") were not adjusted as a result of the Reverse Stock Split. The number of issued and outstanding Preferred Stock were not adjusted as a result of the Reverse Stock Split. However, the conversion ratios for the Company’s Preferred Stock were proportionally adjusted such that the common stock issuable upon conversion of such Preferred Stock was decreased in proportion to the Reverse Stock Split. Likewise, the number of shares issuable upon exercise of outstanding options and common stock warrants and the related exercise price were adjusted in proportion to the Reverse Stock Split. All share and per share references, other than Preferred Stock, have been retroactively adjusted to reflect the effect of the Reverse Stock Split for all periods presented. Initial public offering—On April 16, 2026, the Company’s Registration Statement on Form S-1 for its initial public offering (“IPO”) was declared effective, and on April 20, 2026, the Company completed its IPO of 12,937,500 shares of its common stock (which includes the exercise in full of the underwriters’ option to purchase an additional 1,687,500 shares of common stock), at a price to the public of $17.00 per share. The gross proceeds to the Company from the IPO were $219.9 million and the net proceeds amounted t o $197.8 million after deducting underwriting discounts and commissions and estimated offering expenses incurred by the Company. Immediately prior to the IPO, all of the shares of the Company's Class A common stock, Preferred Stock and Founders Preferred Stock then outstanding converted into shares of the Company's Class B common stock (the "Stock Conversions"). The Company immediately thereafter filed an amended and restated certificate of incorporation, and upon filing of the amended and restated certificate of incorporation, the Company’s Class B common stock was redesignated as common stock (the "Redesignation"). T he Company's outstanding preferred stock warrants also converted into warrants to purchase 31,251 shares of common stock (together with the Stock Conversions, the “Conversions”). Additionally, the Company’s outstanding convertible notes were settled through the issuance of 3,910,025 shares of common stock. The condensed consolidated financial statements as of March 31, 2026 do not give effect to the Conversions, the Redesignation or the IPO, as they occurred subsequent to March 31, 2026. In connection with the closing of the Company’s IPO, the Company increased the authorized number of shares to 1,000,000,000 shares of common stock and 20,000,000 shares of preferred stock. Basis of presentation—The Company’s condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting and include all adjustments necessary for the fair presentation of the Company’s financial position for the periods presented. The condensed results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ended December 31, 2026 or for any other future annual or interim period. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, (the “Securities Act”), on April 17, 2026 (the “Prospectus”). Principles of consolidation—The accompanying condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Risks and uncertainties—The Company is subject to certain risks and uncertainties, including but not limited to the following areas: dependence on key personnel, existing competitors or new market entrants, and dependence upon the availability of cash to sustain operations. The Company’s financial position or operating results may be materially affected by the foregoing factors.
