(the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Leerink Partners LLC and TD Securities (USA) LLC, as representatives of the several underwriters named therein (the “Underwriters”), relating to the offering, issuance and sale of 10,345,000 shares (the “Shares”) of the Company’s common stock, par value $0.001 (the “Common Stock”), at a price to the public of $29.00 per share (the “Offering”). The net proceeds to the Company from the Offering are expected to be approximately $282 million, after deducting underwriting discounts and commissions and other estimated offering expenses payable by the Company. The Offering is expected to close on or about April 6, 2026, subject to customary closing conditions. Pursuant to the Underwriting Agreement, the Underwriters have a 30-day option to purchase up to 1,551,750 additional shares of Common Stock at the purchase price per Share to be paid by the Underwriters (the “Option”).
The Offering is being made pursuant to a prospectus supplement, dated April 1, 2026 (the “Prospectus Supplement”), to be filed with the Securities and Exchange Commission (the “SEC”), and an accompanying base prospectus that forms a part of the Company’s automatically effective shelf registration statement on Form S-3 (File No. 333-275300) previously filed with the SEC.
The Underwriting Agreement contains customary representations, warranties and agreements by the Company, conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, 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 and is qualified in its entirety by reference to the full text of the Underwriting Agreement, a copy of which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated by reference herein.
