Nature of Business | 1. Nature of Business Description of Business CalciMedica, Inc. (“CalciMedica” or the “Company”) (f/k/a Graybug Vision, Inc.) was incorporated in the state of Delaware in February 2015, following the conversion of Graybug, LLC, which was organized in May 2011, and has its principal operations in La Jolla, California. The Company is a clinical-stage biopharmaceutical company focused on developing therapeutics that treat serious illnesses driven by inflammatory processes and direct cellular damage. The Company had a wholly owned subsidiary, CalciMedica Subsidiary, Inc., incorporated in Delaware in October 2006, which survived the Merger as more fully described below. The CalciMedica Subsidiary entity was dissolved and combined with the Company as of December 31, 2024. Reverse Merger Transaction On March 20, 2023, Graybug Vision, Inc. (“Graybug”) completed a reverse merger transaction in accordance with the terms and conditions of the Agreement and Plan of Merger and Reorganization, dated as of November 21, 2022, as amended on February 10, 2023 (the “Merger Agreement”), by and among Graybug, Camaro Merger Sub, Inc., a wholly owned subsidiary of Graybug (“Merger Sub”), and CalciMedica, Inc. (“Private CalciMedica”), pursuant to which Merger Sub merged with and into Private CalciMedica, with Private CalciMedica surviving as a wholly owned subsidiary of Graybug (the “Merger”). Additionally, on March 20, 2023, Graybug changed its name from “Graybug Vision, Inc.” to “CalciMedica, Inc.” and Private CalciMedica changed its name from “CalciMedica, Inc.” to “CalciMedica Subsidiary, Inc.” At the completion of the Merger, the prior Private CalciMedica equity holders and the prior Graybug equity holders owned 72% and 28%, respectively, of the combined company, in each case, on a fully diluted basis using the treasury stock method and excluding out-of-the-money options and warrants. The Merger was accounted for as a reverse recapitalization, with Private CalciMedica being treated as the acquirer for accounting purposes. Liquidity and Need for Additional Capital The Company has experienced net losses and negative cash flows from operating activities since its inception. The Company has an accumulated deficit of $178.6 million as of September 30, 2025 and a net loss of $7.8 million and $18.8 for the three and nine months ended September 30, 2025, respectively. Substantially all of the Company’s operating losses resulted from expenses incurred in connection with its research and development programs and from general and administrative costs associated with its operations. The Company expects to incur significant expenses and increasing operating losses for the foreseeable future as the Company initiates and continues the preclinical and clinical development of its product candidates and adds personnel necessary to operate as a company with an advanced clinical pipeline of product candidates. The Company expects that its operating losses will fluctuate significantly from quarter-to-quarter and year-to-year due to timing of clinical development programs. From inception to September 30, 2025, the Company has completed financings from the sale of preferred and common stock for total net proceeds of $142.5 million and has issued convertible promissory notes and promissory notes for net proceeds of $18.3 million. In connection with the Merger, the Company received approximately $29.4 million of cash, cash equivalents and short-term investments. On February 28, 2025, the Company entered into the (“Loan Agreement”) with Avenue Venture Opportunities Fund II, L.P. and Avenue Capital Management II, L.P. for an initial $10.0 million of gross proceeds. At September 30, 2025, the Company had cash, cash equivalents and short-term investments of approximately $14.1 million. The Company intends to seek additional funding through public and private financings, debt financings, collaboration agreements, strategic alliances and licensing agreements. Although the Company has been successful in raising capital in the past, there is no assurance of success in obtaining such additional financing on terms acceptable to us, if at all, and there is no assurance that the Company will be able to enter into collaborations or other arrangements. In addition, the terms of the Loan Agreement contain certain restrictions on incurring additional indebtedness. If the Company is unable to obtain funding when required or on acceptable terms, the Company may be required to scale back or discontinue the advancement of the product candidates, reduce headcount, file for bankruptcy, reorganize, merge with another entity or cease operations. Based on the Company’s current operating plans, management believes its cash, cash equivalents and short-term investments may not be sufficient to fund its operations for a period of one year following the issuance of these financial statements. As a result, there is substantial doubt about the Company’s ability to continue as a going concern. The unaudited condensed consolidated financial statements have been prepared on a basis which assumes we are a going concern and does 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 any uncertainty related to our ability to continue as a going concern. If the Company becomes unable to continue as a going concern, it may have to liquidate its assets, and might realize significantly less than the values at which they are carried on its financial statements, and stockholders may lose all or part of their investment in the Company’s common stock.
