EXPLANATORY NOTE

This Form 8-A12B/A is being filed by Seanergy Maritime Holdings Corp. (the “Company”) to amend and supplement the original Form 8-A12B filed by the Company with the Securities and Exchange Commission on July 2, 2021, as amended by Amendment No. 1 to Form 8-A12B filed with the SEC on December 14, 2023 (the “Amended Form 8-A”).

Item 1. Description of Registrants’ Securities to be Registered.

This description amends the Amended Form 8-A relating to the preferred stock purchase rights (the “Rights”) issued pursuant to the Shareholders Rights Agreement dated as of July 2, 2021, as amended by the Amended and Restated Shareholders Rights Agreement, dated as of December 13, 2023 (the “Amended Rights Agreement”), by and between the Company and Continental Stock Transfer & Trust Company, as rights agent.

On March 30, 2026, a special independent committee of the Company’s board of directors approved an Amendment No. 1 to the Amended and Restated Shareholders Rights Agreement (the “Rights Agreement”) which, among other things, amends the Amended Rights Agreement to extend the expiration date of the Rights to March 31, 2029. In addition, the agreement was amended such that a person shall not become an Acquiring Person upon becoming the beneficial owner of additional common shares if this does not have the effect of increasing the aggregate voting power of all securities of ours beneficially owned by such person.

The foregoing description of the Rights Agreement and the Rights does not purport to be complete and is qualified in its entirety by reference to Exhibits 3.1, 4.1 and 4.2.
