Amendments to Articles of Incorporation or Bylaws

As previously disclosed in the Registration Statement on Form S-1, as amended (File No. 333-294976) (the “Registration Statement”) of Seaport Therapeutics, Inc. (the “Company”) and in connection with the consummation of the initial public offering of the Company’s common stock (the “IPO”), the Company filed an amended and restated certificate of incorporation (the “Restated Certificate”) with the Secretary of State of the State of Delaware. The Company’s board of directors (the “Board”) and the Company’s stockholders previously approved the Restated Certificate to be filed in connection with, and to be effective immediately prior to, the consummation of the IPO. The Restated Certificate amends and restates the Company’s existing amended and restated certificate of incorporation, as amended, in its entirety to, among other things: (i) authorize 700,000,000 shares of common stock, including 500,000,000 shares of voting common stock and 200,000,000 shares of non-voting common stock; (ii) eliminate all references to the previously-existing series of preferred stock; and (iii) authorize 10,000,000 shares of undesignated preferred stock that may be issued from time to time by the Board in one or more series.

The foregoing description of the Restated Certificate is qualified by reference to the Restated Certificate, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

In addition, as previously disclosed in the Registration Statement and in connection with the consummation of the IPO, the amended and restated bylaws of the Company (the “Amended and Restated Bylaws”), previously approved by the Board and the Company’s stockholders to become effective immediately upon effectiveness of the Registration Statement, became effective. The Amended and Restated Bylaws amend and restate the Company’s bylaws in their entirety to, among other things: (i) establish procedures for the Company’s stockholders to take formal actions at meetings of stockholders; (ii) establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our Board; (iii) establish procedures relating to the nomination of directors; and (iv) conform to the amended provisions of the Restated Certificate.

The foregoing description of the Amended and Restated Bylaws is qualified by reference to the Amended and Restated Bylaws, a copy of which is attached hereto as Exhibit 3.2 and is incorporated herein by reference.
