Rhea-AI Filing Summary

Costamare Inc. announced a governance-focused issuance of 1,200 shares of new high-vote, non-economic Series F Preferred Stock to Konstantinos Konstantakopoulos for an aggregate $1,200. Each preferred share carries 50,000 votes, increasing the Konstantakopoulos family’s voting power from 63.6% to 75.7%.

The move follows a Chinese Ministry of Transport announcement on special port fees for U.S.-linked vessels and is designed to ensure U.S. persons cannot control over 25% of the Company’s voting power. The Series F carries no dividends or distributions beyond par value on liquidation. Shares are redeemable at $1 per share at any time at the sole discretion of independent directors, and all rights automatically terminate on the fifth anniversary of issuance. The Audit Committee, composed solely of independent and disinterested directors, reviewed and unanimously recommended approval.

Insights

Voting control rises to 75.7% via non-economic super-vote shares with a 5-year sunset.

Costamare issued 1,200 Series F Preferred shares for $1,200, each with 50,000 votes. This lifts the Konstantakopoulos family’s voting power from 63.6% to 75.7%, while leaving economic rights unchanged (no dividends, only par on liquidation). The structure concentrates voting power without diluting cash flows.

The issuance is positioned in response to China’s special port fee announcement for U.S.-linked vessels, aiming to ensure U.S. persons do not control over 25% of voting power. A redemption right at $1 per share resides with independent directors, and all rights terminate after five years, adding governance safeguards.

Key features to track are the redemption discretion of independent directors and the automatic termination on the fifth anniversary (October 2026–2030 window implied by issuance date), which define the duration and reversibility of the voting shift.

Stock Subscription Agreement, dated as of October 15, 2025, between Costamare Inc. and Konstantinos Konstantakopoulos


Monaco, October 15, 2025 – Costamare Inc. (“Costamare” or the “Company”) (NYSE: CMRE) announced today that it has entered into a Stock Subscription Agreement (the “Purchase Agreement”) with Konstantinos Konstantakopoulos, pursuant to which Mr. Konstantakopoulos will purchase 1,200 shares of a new series of high-vote, non-economic preferred stock (the “Series F Preferred Stock”), for an aggregate purchase price of $1,200.

Each share of Series F Preferred Stock shall entitle Mr. Konstantakopoulos to 50,000 votes on all matters submitted to a vote of the shareholders of the Company.  The Series F Preferred Stock were established in connection with the announcement on October 10, 2025, by the Ministry of Transport in China relating to the collection of special port fees from U.S.-linked vessels. While the Company does not believe that its vessels are subject to the collection of special port fees, the issuance of the Series F Preferred Stock ensures that it is not possible for U.S. persons to control over 25% of the voting power of the Company because, following the completion of the purchase by Mr. Konstantakopoulos, members of the Konstantakopoulos family (none of whom are U.S. persons) will control approximately 75.7% of the Company’s issued and outstanding voting rights. Prior to the issuance of the shares of Series F Preferred Stock pursuant to the Purchase Agreement, the Konstantakopoulos family controlled approximately 63.6% of the Company’s issued and outstanding voting rights.

The Series F Preferred Stock shall not have any dividend or distribution rights, and shall not be entitled to any distributions upon any liquidation, dissolution or winding up of the Company other than its par value. All shares of the Series F Preferred Stock are subject to redemption by the Company at any time in the sole discretion of the independent members of the Board of Directors of the Company (or a committee comprised thereof) and without the consent of the holders of Series F Preferred Stock, for a redemption price equal to $1 per share. Effective on the date that is the fifth anniversary of the date of issuance of the shares of Series F Preferred Stock, all rights and powers of any such shares that remain outstanding will automatically terminate and be of no further force or effect.

The Audit Committee of the Company, comprised solely of independent and disinterested directors, reviewed the Purchase Agreement and the Statement of Designation establishing the Series F Preferred Stock and unanimously recommended that the Board of Directors of the Company approve the designation and issuance of the Series F Preferred Stock and the execution of the Purchase Agreement.

The terms of the Series F Preferred Stock are set forth in a Statement of Designation of Rights, Preferences and Privileges of Series F Preferred Stock of the Company, dated as of October 15, 2025 (the “Statement of Designation”), a copy of which is attached hereto as Exhibit 99.1.
