Explanatory Note

This Current Report on Form 8-K/A (this “Amendment”) is being filed as a supplement to the Current Report on Form 8-K filed by Galecto, Inc., a Delaware corporation (the “Company”), on November 10, 2025 (the “Original Report”). The Original Report was filed, among other things, to report the filing of the Company’s Certificate of Designation of Preferences, Rights and Limitations of Series C Preferred Stock (the “Certificate of Designation of Series C Preferred Stock”) with the Secretary of State of the State of Delaware (the “Delaware Secretary of State”). This Amendment amends the Original Report solely to update the disclosure regarding the Certificate of Designation of Series C Preferred Stock, and to disclose that the Company has filed a certificate of correction to the Certificate of Designation of Series C Preferred Stock to correct an error contained in the Certificate of Designation of Series C Preferred Stock.

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

On December 5, 2025, the Company filed with the Delaware Secretary of State a Certificate of Correction (the “Certificate of Correction”) to the Certificate of Designation of Series C Preferred Stock to correct an inadvertent error in the number of shares of Series C Non-Voting Convertible Preferred Stock, par value $0.00001 per share (the “Series C Preferred Stock”), that the Company is authorized to issue by modifying Section 2 of the Certificate of Designation of Series C Preferred Stock to correctly state that the number of authorized shares of Series C Preferred Stock is 43,882 shares instead of 43,855 shares.

The foregoing description of the Certificate of Correction does not purport to be complete and is qualified in its entirety by reference to the Certificate of Correction, a copy of which is filed as Exhibit 3.3 to this Current Report on Form 8-K/A and is incorporated herein by reference.
