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.**&nbsp;&nbsp;&nbsp;&nbsp; **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.

This Amendment No. 1 to the Amended and Restated Shareholders' Rights Agreement, effective as of March 30, 2026 (this "<u>Amendment</u>"), amends that certain Amended and Restated Shareholders' Rights Agreement, dated as of December 13, 2023 (the "<u>Rights Agreement</u>"), by and between Seanergy Maritime Holdings Corp., a Marshall Islands corporation (the "<u>Company</u>"), and Continental Stock Transfer & Trust Company, as rights agent (the "<u>Rights Agent</u>"). Capitalized terms used herein but not defined herein shall have their defined meanings set forth in the Rights Agreement.

WHEREAS, pursuant to Section 27 of the Rights Agreement and under the circumstances specified therein, the Company and the Rights Agent may amend the Rights Agreement in any respect without the approval of any holders of the Rights;

WHEREAS, the Company and the Rights Agent now desire to amend the Rights Agreement as set forth in this Amendment; and

WHEREAS, a special independent committee of the Board of Directors of the Company has determined that this Amendment and the transactions contemplated hereby are advisable and in the best interests of the Company and the holders of Common Shares.

NOW, THEREFORE, the parties hereto hereby agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The following sentence shall be added as the last sentence of the definition of "Acquiring Person" appearing in Section 1 of the Rights Agreement:

"Notwithstanding anything to the contrary set forth herein, a Person shall not be or become an Acquiring Person upon becoming the Beneficial Owner of additional Common Shares if such Person's becoming the Beneficial Owner of such additional Common Shares does not have the effect of increasing the aggregate voting power of all securities of the Company Beneficially Owned by such Person, unless and until such time as such Person shall become the Beneficial Owner of additional Common Shares (other than pursuant to an additional grant under a Company equity incentive plan, dividend or distribution paid or made by the Company on the outstanding Common Shares in Common Shares or pursuant to a split or subdivision of the outstanding Common Shares) and (i) such Person's becoming the Beneficial Owner of such additional Common Shares has the effect of increasing the aggregate voting power of all securities of the Company Beneficially Owned by such Person and (ii) upon becoming the Beneficial Owner of such additional Common Shares such Person would otherwise be an Acquiring Person."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The definition of "Final Expiration Date" appearing in Section 1 of the Rights Agreement shall be amended and restated in its entirety as follows:

------

"<u>Final Expiration Date</u>" shall mean the Close of Business on March 31, 2029.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; This Amendment shall be effective as of the date of this Amendment, and all references to the Rights Agreement shall, from and after such time, be deemed references to the Rights Agreement as amended hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Except as expressly set forth herein, this Amendment shall not by implication or otherwise alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants, or agreements contained in the Rights Agreement, all of which are ratified and affirmed in all respects and shall continue in full force and effect and shall be otherwise unaffected.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; This Rights Agreement and each Right and each Rights Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of New York and for all purposes shall be governed by and construed in accordance with the laws of such State applicable to contracts to be made and performed entirely within such State.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; This Amendment may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. Delivery of an executed signature page of this Amendment by facsimile or other customary means of electronic transmission (e.g., "pdf") shall be effective as delivery of a manually executed counterpart hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The undersigned officer of the Company, being duly authorized on behalf of the Company, hereby certifies in such officer's capacity as an officer of the Company to the Rights Agent by execution hereof that this Amendment is in compliance with the terms of Section 27 of the Rights Agreement.
