Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On August 1, 2025, Shoulder Innovations, Inc. (the “Company”) filed an amended and restated certificate of incorporation (the “Restated Certificate”) with the Secretary of State of the State of Delaware in connection with the closing of the initial public offering (the “IPO”) of shares of its common stock. The Company’s board of directors and stockholders previously approved the filing of the Restated Certificate upon the closing of the IPO.

The Restated Certificate amended and restated the Company’s prior Fourth Amended and Restated Certificate of Incorporation, as amended, in its entirety, to, among other things: (i) fix the authorized number of shares of common stock at 730,000,000 shares; (ii) eliminate all references to the previously existing series of preferred stock; (iii) authorize 20,000,000 shares of undesignated preferred stock that may be issued from time to time by the Company’s board of directors in one or more series; (iv) establish a classified board of directors, divided into three classes, each of whose members will serve for staggered three-year terms; (v) provide that directors may be removed from office only for cause and only upon the affirmative vote of the holders of at least two-thirds of the Company’s capital stock entitled to vote thereon; (vi) require the advance notice of nominations for election to the board of directors or for proposing matters that can be acted upon at a stockholders’ meeting in the manner provided in the Company’s bylaws then in effect; (vii) eliminate the ability of the Company’s stockholders to take action by written consent in lieu of a meeting; (viii) designate the Court of Chancery of the State of Delaware to be the sole and exclusive forum for certain actions, including, but not limited to, derivative actions, suits or proceedings brought on behalf of the Company or actions, suits or proceedings asserting claims of breach of a fiduciary duty owed by any of the Company’s directors, officers or stockholders, provided that the exclusive forum provision will not apply to actions brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction; and (ix) designate the federal district courts of the United States of America to be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended.

The foregoing description of the amendments made by 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.

On August 1, 2025, in connection with the closing of the IPO, the amended and restated bylaws of the Company (the “Amended and Restated Bylaws”), previously approved by the Company’s board of directors to become effective upon the effectiveness of the Restated Certificate, became effective. The Amended and Restated Bylaws amended and restated the Company’s prior Second Amended and Restated Bylaws in their entirety to, among other things: (i) establish procedures relating to the presentation of stockholder proposals at stockholder meetings; (ii) establish procedures relating to the nomination of directors; and (iii) conform to the amended provisions of the Restated Certificate.

The foregoing description of the amendments made in 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.
