Description of Business, Organization, and Liquidity | Description of Business, Organization, and Liquidity Bicara Therapeutics Inc. (“Bicara” or the “Company”) was incorporated in the state of Delaware in December 2018 and is a clinical-stage biopharmaceutical company based in Boston, Massachusetts. The Company is committed to bringing transformative bifunctional therapies to patients with solid tumors. Its lead program ficerafusp alfa is a bifunctional antibody that combines a clinically validated epidermal growth factor receptor directed monoclonal antibody bound to a human transforming growth factor beta ligand trap. Since inception, the Company has operated in the preclinical and clinical stages and has devoted substantially all of its time and efforts to performing research and development activities, raising capital, and recruiting management and technical staff to support these operations. The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry including, but not limited to, risks associated with the successful research, development and manufacturing of product candidates, competition from other companies, dependence on key personnel, protection of intellectual property, compliance with government regulations and the ability to secure additional capital to fund operations. Current and future programs will require significant research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure. Even if our product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales. The Company historically has funded its operations from the issuance of common stock in connection with its initial public offering (“IPO”), issuance of common stock in connection with its at-the-market offering program (the “ATM Program”), issuance of equity securities in a public offering in February 2026, redeemable convertible preferred stock and through debt financing. On September 16, 2024, the Company closed its IPO, through which it issued 20,125,000 shares of common stock with par value of $0.0001 per share and a purchase price of $18.00 per share. The Company raised net proceeds of $332.4 million from the issuance of common stock. In December 2025, the Company issued 1,604,000 shares of common stock with par value of $0.0001 per share through the ATM Program and raised net proceeds of $29.5 million. In February 2026, the Company issued and sold 8,581,250 shares of its common stock, including 1,406,250 shares pursuant to the exercise of the underwriters’ option to purchase additional shares, at a price to the public of $16.00 per share. Further, in lieu of common stock to certain investors, the Company sold pre-funded warrants to purchase 2,200,000 shares of common stock at a public offering price of $15.9999 per pre-funded warrant, which represents the per share public offering price of each share of common stock less the $0.0001 per share exercise price for each pre-funded warrant. As a result of the offering, the Company received approximately $161.8 million in net proceeds. The Company has incurred operating losses since inception and expects such losses and negative operating cash flows to continue for the foreseeable future. As of March 31, 2026, the Company had cash, cash equivalents and marketable securities of $539.8 million and an accumulated deficit of $415.2 million. The Company expects that its cash, cash equivalents and marketable securities as of March 31, 2026 of $539.8 million will be sufficient to fund the operating expenditures and capital expenditure requirements necessary to advance its research efforts and clinical trials for at least one year from the date of issuance of these unaudited condensed consolidated financial statements.
