Also Urges Genco Shareholders to Vote the GOLD Universal Proxy Card "FOR" Jens Ismar and Paul Cornell Ahead of the Annual Meeting on June 18, Who Will Bring Much-Needed Fresh Perspectives to the Genco Board, and "WITHHOLD" on Basil G. Mavroleon and Arthur L. Regan

ATHENS, Greece, June 15, 2026 (GLOBE NEWSWIRE) -- Diana Shipping Inc. (NYSE:DSX) ("Diana" or "the Company"), a global shipping company specializing in the ownership and bareboat charter-in of dry bulk vessels that is the largest shareholder of Genco Shipping & Trading Limited (NYSE:GNK) ("Genco"), today addressed a series of new conditions regarding Genco's poison pill that have been announced by the Genco Board of Directors (the "Board").

Diana urges shareholders not to be distracted by Genco's blatant attempt to confuse shareholders with empty promises. After Institutional Shareholder Services Inc.'s ("ISS") recommendation that Genco shareholders vote AGAINST the ratification of Genco's poison pill, the Genco Board had an opportunity to demonstrate its supposed "commitment to strong corporate governance and shareholder engagement" and indicate that it would rescind the poison pill if shareholders vote against it. Instead, the Board chose to cling to the poison pill – the centerpiece of its entrenchment strategy – and reaffirm its commitment to maintaining the pill with a few self-serving, meaningless last minute qualifications. Genco shareholders should not be manipulated into accepting such a poison pill. Genco has a simple responsibility:

If Genco Shareholders Vote Against the Poison Pill, the Board Should Immediately Rescind the Poison Pill.

In its most recent manifesto about the poison pill, Genco made claims that Diana's purchases of Genco shares were not properly disclosed. These claims are a distraction that Genco is using to justify a defensive measure that is contrary to shareholder interests. Genco tries to justify this shareholder democracy failure by saying the situation is "different and unique" with no explanation. Genco should explain to its shareholders what really is "different and unique" here, other than the fact that Diana has presented a fully financed, all-cash premium offer to Genco shareholders.

It should also be noted that, conveniently, the Genco Board did not make any "commitments" regarding the poison pill's qualifying offer clause, which includes atypical features that are particularly powerful for entrenching the Genco Board and management team with respect to Diana's offer.

In its report about the proxy contest, ISS made the following comments about the terms of the poison pill:

• To be a qualifying offer under the terms of the Genco poison pill,  "the offer price must be in excess of the highest reported market price of GNK shares in the preceding 24 months (with the value of any equity consideration determined based on the lowest reported market price for the bidder's shares in the five days before and after the commencement of the offer)."
  
  
  
  
• "Concerns are compounded by the requirement that the offer remain open for a potentially extensive period."
  
  
  
  
• "Moreover, the pill will not be redeemed automatically if the tender offer is within the pill's parameters but merely cease to apply to the offer so long as it remains a qualifying offer. This may be more difficult than it appears: for example, given the minimum price requirement, any spike in the GNK share price past the offer price, no matter how briefly sustained, may result in the offer no longer being considered a qualifying offer."
  
  
  
  
• On balance, this qualified offer clause does not appear to provide a reasonable means for redemption of the poison pill if another party attempts to acquire the company.
  
  

*Diana has neither sought nor obtained consent from ISS to use previously published information in this press release.

Diana believes the best way for shareholders to ensure that their interests are properly considered is to send the Board a clear and decisive message about their track record of entrenchment favoring the interests of Genco management over shareholders by voting:

• FOR Diana's nominees Jens Ismar and Paul Cornell, who would bring necessary fresh, independent perspectives to the Genco Board;
• WITHHOLD on Basil G. Mavroleon and Arthur L. Regan;
• AGAINST Genco's proposal to ratify its poison pill; and
• AGAINST Genco's proposal to ratify its equity incentive plan.

Mr. Ismar and Mr. Cornell are independent drybulk executives who would bring fresh perspectives and directly relevant expertise to the Genco Board and would work alongside the tenured directors already in place to consider all opportunities to create value for shareholders — including rescinding the poison pill.

Diana believes Genco shareholders deserve a Board that will act to serve their interests — and that Jens Ismar and Paul Cornell are exactly the kind of independent, experienced voices needed to bring fresh perspectives into the boardroom and ensure all strategic opportunities are properly evaluated on behalf of all shareholders.

Diana has updated its GOLD universal proxy card to reflect its updated slate and recommendation that shareholders vote "FOR" Jens Ismar and Paul Cornell and WITHHOLD on Genco nominees Basil G. Mavroleon and Arthur L. Regan.

Shareholders who have already voted on the previously circulated GOLD card for Mr. Ismar and Mr. Cornell do not need to take any additional action — votes for Ismar and Cornell will be counted. Shareholders who have voted the WHITE card can change their vote by signing, dating and returning the GOLD universal proxy card. Only the latest-dated proxy will count. Please act as soon as possible —the Annual Meeting is on June 18, 2026.

Diana also reminds shareholders that its $24.80 per share all-cash tender offer remains live. Shareholders who have not yet tendered their shares are encouraged to do so prior to the tender offer's expiration at 5:00 p.m., New York City time, on June 26, 2026, unless further extended. The proxy vote and the tender offer are independent of each other — shareholders can and should act on both.

Information Regarding the Offer

On May 4, 2026, Diana commenced a tender offer (the "Offer"), through its wholly owned subsidiary 4 Dragon Merger Sub Inc., to purchase all outstanding shares of Genco common stock at $23.50 per share in cash. On May 27, 2026, Diana (i) increased the offer price from $23.50 per share in cash to $24.80 per share in cash, and (ii) extended the expiration of the Offer to 5:00 p.m., New York City time, on June 26, 2026, unless further extended. To the extent that Genco declares a cash dividend or other distribution on the Genco shares, the offer price will be reduced by the amount payable per share.

The Offer is conditioned upon, among other things: (i) Genco entering into a definitive merger agreement with Diana substantially in the form of the merger agreement included with the Offer documents; (ii) Genco shareholders validly tendering a majority of Genco's outstanding shares on a fully diluted basis; (iii) the termination or inapplicability of Genco's shareholder rights plan; (iv) the Genco Board's approval of the transaction under certain affiliate transaction provisions in Genco's charter and (v) other customary conditions. Satisfaction of the merger agreement condition, the shareholder rights plan condition and the affiliate transaction condition is solely within the control of Genco and the members of the Genco Board.

If the Offer is successfully completed, Diana intends to consummate a second-step merger as promptly as practicable, in which any remaining Genco shareholders who did not tender their shares in the Offer would receive the same $24.80 per share in cash that was paid in the Offer. As a result, if the Offer is completed and the second-step merger is consummated, all Genco shareholders — whether or not they tender their shares — would receive $24.80 per share in cash. Importantly, shareholders who tender in the Offer may receive their cash sooner than those whose shares are acquired in the second-step merger.

The Offer to Purchase and related Letter of Transmittal are being mailed to Genco shareholders and will be filed with the U.S. Securities and Exchange Commission. Copies of these materials will be available at no charge on the SEC's website at www.sec.gov.
