Vafias in his personal capacity (sometimes collectively referred to as the “Reporting Persons”).

Information given in response to each item below shall be deemed incorporated by reference in all other items below. Unless indicated otherwise, all items left blank remain unchanged, and any items which are amended below are deemed to amend and update the existing items in the Schedule 13D.

All Common Stock share amounts reflect the 1-for-100 reverse split of the Common Stock effected by the Issuer on April 11, 2024, at 11:59 p.m., Eastern time.

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 of the Statement is hereby amended by adding the following paragraphs to the end of Item 3:

On June 18, 2024 and June 20, 2024, Arethusa acquired an aggregate of 395,148 shares of Common Stock for an aggregate of $501,334 (including commissions) in open market purchases using its working capital.

Mr. Vafias is the Chief Executive Officer, President and Chairman of Imperial Petroleum Inc., which owns 600,000 shares of the Issuer’s outstanding Series A Convertible Preferred Stock, par value $0.01 per share, liquidation preference $25.00 per share, which is convertible, at the holder’s option, into Common Stock at a current conversion price of $1.2573.

This Amendment No. 1 also updates the percentage of Common Stock of the Issuer beneficially owned by the Reporting Persons, including to reflect issuances of shares of Common Stock by the Issuer pursuant to the exercise of outstanding warrants.

Item 4.

Purpose of Transaction.

The Reporting Persons acquired the securities described in this Schedule 13D for investment purposes and intend to review their investment in the Issuer on a continuing basis. Any Reporting Person may from time to time acquire additional securities of the Issuer, or retain or sell all or a portion of the shares then held by the Reporting Persons, in the open market, block trades, underwritten public offerings or privately negotiated transactions. Any actions any Reporting Person might undertake with respect to its investment in the Issuer may be made at any time and from time to time and will be dependent upon such Reporting Person’s review of numerous factors, including, but not limited to: ongoing evaluation of the Issuer’s business, financial condition, operations, prospects and strategic alternatives; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; tax considerations; liquidity of the Issuer’s securities; and other factors and future developments.

Mr. Vafias serves as the Non-Executive Chairman of the Issuer and therefore regularly engages in discussions with management of the Issuer, the board of directors of the Issuer, other shareholders of the Issuer and other relevant parties, which discussions may include matters ranging from the operations and conduct of the Issuer’s business to considering or exploring extraordinary corporate transactions including the events listed in Items 4(a) through 4(j) of Schedule 13D. In connection with these discussions, the Reporting Persons may, either directly or through one or more affiliates, determine to take any available course of action or to take no course of action and may at any time and from time to time take steps to further or implement such course of action, including any of the events listed in Items 4(a) through 4(j) of Schedule 13D. Any action or actions the Reporting Persons may undertake with respect to their investment in the Issuer or the operations and conduct of the Issuer’s business will be dependent upon the Reporting Persons’ review of numerous factors, including those listed above, and the Reporting Persons specifically reserve the right to change their intentions, or to formulate plans and proposals, with respect to any or all of the matters described in this paragraph, subject to applicable law and regulations.
