Other Events

On February 5, 2026, the Board of Directors (the “Board”) of Shattuck Labs, Inc. (the “Company”) determined that the 2026 annual meeting of stockholders (the “Annual Meeting”) will be held on Thursday, May 28, 2026. All other relevant information concerning the 2026 Annual Meeting will be included in the Company’s proxy materials to be distributed, which will be made available to stockholders and filed with the Securities and Exchange Commission (“SEC”) at a later date.

Because the scheduled date of the 2026 Annual Meeting is more than 30 days before the anniversary of the prior annual meeting, the deadlines for stockholders to propose actions for consideration or to nominate individuals to serve as directors at the 2026 Annual Meeting previously set forth in the Company’s 2025 proxy statement filed with the SEC on May 21, 2025 (the “2025 Proxy Statement”) are no longer applicable. In accordance with SEC rules, the Company is providing notice of revised deadlines in connection with the 2026 Annual Meeting:

•

To be considered for inclusion in the Company’s proxy materials for the 2026 Annual Meeting, stockholder proposals submitted pursuant to SEC Rule 14a-8 must be received no later than the close of business on February 15, 2026.

•

To be considered at the 2026 Annual Meeting, director nominations and stockholder proposals submitted pursuant to the advance notice provisions of the Company’s Bylaws (other than pursuant to SEC Rule 14a-8) must be received not earlier than the close of business on January 28, 2026, and not later than close of business on February 27, 2026.

Please refer to the 2025 Proxy Statement for more information. Any such stockholder proposals and director nominations must comply with SEC Rule 14a-8 and the Company’s Bylaws, as applicable. The Company reserves the right to reject, rule out of order, or take other appropriate action with respect to any nomination or proposal that does not comply with these and other applicable requirements.
