Item 1.01 Entry into a Material Definitive Agreement.

On January 21, 2026, BioAge Labs, Inc., a Delaware corporation (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Goldman Sachs & Co. LLC, Piper Sandler & Co. and Citigroup Global Markets Inc. as representatives of the underwriters named therein (the “Underwriters”), pursuant to which the Company agreed to issue and sell 5,897,435 shares (the “Underwritten Shares”) of its common stock, par value $0.00001 per share (“Common Stock”) to the Underwriters in a public offering at a price of $19.50 per Underwritten Share (the “Offering”). Pursuant to the Underwriting Agreement, the Company has also granted the Underwriters a 30-day option to purchase up to an additional 884,615 shares of its Common Stock (the “Option Shares,” and together with the Underwritten Shares, the “Shares”).

The Underwriting Agreement contains customary representations and warranties, conditions to closing, market standoff provisions, termination provisions and indemnification obligations, including for liabilities under the Securities Act of 1933, as amended. The Offering is being made pursuant to the shelf registration statement on Form S-3 (File No. 333-290688) that was filed by the Company with the Securities and Exchange Commission (“SEC”) on October 2, 2025, as amended on November 5, 2025, and which became effective through operation of law on November 25, 2025, and a related prospectus supplement and free-writing prospectus.

The Company estimates that net proceeds from the Offering will be approximately $107.6 million, after deducting underwriting discounts and commissions and estimated Offering expenses, and assuming no exercise of the Underwriters’ option to purchase additional shares. The Company intends to use the net proceeds of the Offering, together with its existing cash, cash equivalents and marketable securities, to fund research, clinical and process development and manufacturing of its product candidates, including BGE-102 and further development of its NLRP3 and APJ programs, working capital, capital expenditures, reduction of indebtedness and other general corporate purposes. The Company expects the Offering to close on January 23, 2026, subject to the satisfaction of customary closing conditions.

The Underwriting Agreement is filed as Exhibit 1.1 to this report, and the foregoing description of the terms of the Underwriting Agreement is qualified in its entirety by reference to such exhibit. A copy of the opinion of Fenwick & West LLP, relating to the validity of the Shares in connection with the Offering, is filed with this Current Report on Form 8-K as Exhibit 5.1.

Item 7.01 Regulation FD Disclosure.

On January 21, 2026, the Company issued a press release announcing the pricing of the Offering. A copy of the press release is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information furnished in this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any other filing under the Exchange Act or the Securities Act, except as expressly set forth by specific reference in such a filing.
