ITEM 8.01 — Other Events.

On May 29, 2024, Insmed Incorporated (the “Company”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with Goldman Sachs & Co. LLC and Leerink Partners LLC as representatives of the several underwriters (the “Underwriters”), pursuant to which, subject to satisfaction of the conditions set forth therein, the Company has agreed to sell to the Underwriters, and the Underwriters have agreed to purchase from the Company, 12,621,359 shares (the “Firm Shares”) of the common stock, par value $0.01 per share, of the Company (the “Common Stock”). The Company also granted the Underwriters a 30-day option to purchase up to an additional 1,893,203 shares of Common Stock (together with the Firm Shares, the “Shares”), which the Underwriters exercised in full on May 30, 2024. The Underwriters will purchase the Shares from the Company at a price, after underwriting discounts and commissions, of $49.1825 per share, resulting in net proceeds to the Company before other estimated offering expenses payable by the Company of approximately $713.9 million.

The offering of the Shares (the “Offering”) is being made pursuant to the Company’s shelf registration statement on Form S-3 (Registration Statement No. 333-272088) that became automatically effective upon filing with the Securities and Exchange Commission (the “SEC”) on May 19, 2023, which includes a base prospectus dated May 19, 2023 (the “Registration Statement”), as supplemented by a preliminary prospectus supplement filed with the SEC on May 29, 2024, and a final prospectus supplement dated May 29, 2024 and filed with the SEC on May 30, 2024.

The Company made certain customary representations, warranties and covenants in the Underwriting Agreement concerning the Company, the Registration Statement and the Offering. The Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company and the Underwriters expect to consummate the sale and purchase of the Firm Shares pursuant to the Underwriting Agreement on May 31, 2024, subject to the satisfaction of customary closing conditions.

A copy of the Underwriting Agreement is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated by reference herein. The foregoing description of the terms of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the Underwriting Agreement.
