Item 3.

Item 3 of the Current Schedule 13D is hereby amended and supplemented to add the following:

Item 4.

Purpose of Transaction

 

Item 4 of the Current Schedule 13D is hereby amended and supplemented to add the following:

 

On June 17, 2026, the Reporting Persons submitted a revised proposal (the “June Offer Letter”) to the board of directors of the Issuer to acquire all of the issued and outstanding Common Shares not already owned by the Reporting Persons for $27.34 in total implied value per share, comprised of $24.80 in cash plus one share of common stock of Diana, with the implied value based on the volume-weighted average price per Diana share for the 30 days ended on June 16, 2026 of $2.54 (the “Proposed Transaction”).

 

This revised offer represents:

 

- a 53% premium to the closing price of the Shares on November 21, 2025, the last trading day before the Reporting Persons’ initial acquisition proposal;

 

- a 6% premium to the Issuer’s net asset value (“NAV”) per Share based on vessel valuations provided by VesselsValue; and

 

- a 16% premium to the closing price of the Shares of $23.51 on June 16, 2026.

 

A copy of the June Offer Letter is attached hereto as Exhibit (a)(5)(T) and is incorporated herein by reference.

 

The June Offer Letter is non-binding, and no agreement, arrangement, or understanding between the Reporting Persons and the Issuer relating to the June Offer Letter, the Proposed Transaction, or any other transaction currently exists or will be created until such time as a definitive agreement has been executed and delivered. The Reporting Persons may at any time amend, pursue, or choose not to pursue the Proposed Transaction; change the terms of the Proposed Transaction, including the price or the conditions of the Proposed Transaction; or take action to facilitate or increase the likelihood of consummation of the Proposed Transaction.

 

The Proposed Transaction would result in one or more of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, including an extraordinary corporate transaction involving the Issuer, a change in the present board of directors or management of the Issuer, the termination of the registration of the Shares under the Securities Act of 1934, and the delisting of a class of securities of the Issuer from the New York Stock Exchange. The Reporting Persons may, at any time and from time to time, formulate other plans or proposals regarding the Issuer and the Shares, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of Item 4 of Schedule 13D.

 

In connection with the submission of the June Offer Letter to the Issuer, the Reporting Persons issued the Press Release attached hereto as Exhibit (a)(5)(U), which is incorporated herein by reference.

 

Item 6.
