UNDERWRITTEN OFFERING
On August 1, 2025, I-Mab (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Leerink Partners LLC as the representative of the several underwriters named therein (the “Underwriters”), in connection with the issuance and sale by the Company in an underwritten offering (the “Offering”) of 33,333,330 American depositary shares (“ADSs”), each ten (10) American depositary shares representing twenty-three (23) ordinary shares, representing, in the aggregate, 76,666,659 ordinary shares, par value $0.0001 per share, of the Company at an offering price of $1.95 per ADS. Gross proceeds from the Offering, before deducting underwriting discounts and commissions and offering expenses payable by the Company, are expected to be approximately $65 million.
The Offering was made pursuant to the Company’s shelf registration statement on Form F-3 (File No. 333-286954), which was declared effective by the Securities and Exchange Commission (the “SEC”) on May 15, 2025, as supplemented by a prospectus supplement dated August 1, 2025, filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”). The Offering is expected to close on or about August 5, 2025, subject to customary closing conditions.
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 under the Securities Act, and other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for 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 Underwriting Agreement is not complete, does not purport to be a complete description of the rights and obligations of the parties thereunder, and is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is filed herewith as Exhibit 1.1 and incorporated by reference herein.
The legal opinion of Harneys Westwood & Riegels, the Company’s counsel as to Cayman Islands law, relating to the legality of the issuance and sale of the ordinary shares underlying the ADSs offered in the Offering is filed herewith as Exhibit 5.1 and incorporated by reference herein.
