Item 1.01

Entry into a Material Definitive Agreement.

On July 1, 2025, ArriVent BioPharma, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Goldman Sachs & Co. LLC, Citigroup Global Markets Inc., and Guggenheim Securities, LLC as representatives of the several underwriters named therein (the “Underwriters”), relating to the issuance and sale in an underwritten public offering (the “Offering”) by the Company of an aggregate of 2,482,692 shares (the “Firm Shares”) of the Company’s common stock, $0.0001 par value per share (the “Common Stock”), at a public offering price of $19.50 per Share (as defined below), and, in lieu of shares of Common Stock to certain investors, pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 1,363,469 shares of Common Stock at a public offering price of $19.4999 per Pre-Funded Warrant, which represents the per share public offering price for the Shares less the $0.0001 per share exercise price for each Pre-Funded Warrant. The gross proceeds to the Company from the Offering are expected to be approximately $75 million before deducting underwriting discounts and commissions and other offering expenses. Under the terms of the Underwriting Agreement, the Underwriters have an option, exercisable for 30 days, to purchase up to an additional 576,923 shares of Common Stock (the “Optional Shares” and, together with the Firm Shares, the “Shares”) at the public offering price less underwriting discounts and commissions. All of the securities of the Company in the Offering are being sold by the Company. The Offering is expected to close on or about July 3, 2025, subject to customary closing conditions.

The Shares and Pre-Funded Warrants in the Offering will be issued pursuant to the Company’s automatic shelf registration statement on Form S-3ASR (File No. 333-284661), which was filed with and automatically declared effective by the Securities and Exchange Commission (the “Commission”) on February 3, 2025. A prospectus and final prospectus supplement relating to the Offering (the “Final Prospectus Supplement”) will be filed with the Commission on July 2, 2025 pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”).

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities arising under the Securities Act, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for the purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement and may be subject to limitations agreed upon by the contracting parties.

The foregoing description of the terms of the Underwriting Agreement is qualified in its entirety by reference to the Underwriting Agreement, which is attached as Exhibit 1.1 hereto and incorporated by reference herein.

The Pre-Funded Warrants are exercisable at any time after their original issuance. A holder of Pre-Funded Warrants may not exercise the Pre-Funded Warrant if the holder, together with its affiliates, would beneficially own more than 4.99%, or, at the election of such holder upon issuance, 9.99%, of the number of shares of common stock outstanding or more than 4.99%, or, at the election of such holder upon issuance, 9.99%, of the combined voting power of the Company’s securities outstanding immediately after giving effect to such exercise. A holder of Pre-Funded Warrants may increase or decrease this percentage to any other percentage not exceeding 19.99%, in the case of an increase, upon 61 days’ prior notice to the Company. The foregoing description of the terms of the Pre-Funded Warrants is qualified in its entirety by reference to the form of Pre-Funded Warrant, which is attached as Exhibit 4.1 hereto and incorporated by reference herein.

A copy of the legal opinion of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. relating to the validity of the issuance and sale of the Shares and shares of common stock issuable upon exercise of the Pre-Funded Warrants and the validity of the Pre-Funded Warrants offered in the Offering is attached as Exhibit 5.1 hereto.
