Diana Shipping Inc. Reaffirms Offer to Acquire Genco Shipping & Trading

The Genco Board Has a Responsibility to Deliver on its Commitments to Create Value for Shareholders

Urges the Genco Board to Engage in Good Faith with Respect to Diana's Offer of $27.34 Per Share, Comprised of $24.80 in Cash and One Diana Share

ATHENS, Greece, June 18, 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 reaffirmed its commitment to its offer to acquire Genco. On June 17, 2026, Diana increased its offer to acquire all outstanding shares of Genco not already owned by Diana to a total implied value of $27.34 per share, comprised of $24.80 per share in cash plus one Diana share valued at $2.54 based on Diana's volume-weighted average price per share for the 30 days ended on June 16, 2026 (the "Revised Offer").

The Revised Offer represents a 53% premium to Genco's undisturbed share price and a 6% premium to Genco's net asset value per share based on VesselsValue data, at cyclically high drybulk asset values that are at or near 15-year highs.

Now that the Genco Board has been reelected, it bears a clear and heightened responsibility to deliver to all shareholders the significant value and dividends that it promised during the recent proxy campaign.

Semiramis Paliou, Diana's Chief Executive Officer, commented:

"Today's outcome does not — and will not — in any way diminish our commitment to acquiring Genco and delivering attractive value to all shareholders. We have spent more than six months making the case that our offer represents compelling and certain value for Genco shareholders, but the Genco Board has rejected our offer three times without meaningful engagement, a counterproposal, or a credible alternative path to value creation.

"As Genco's largest shareholder, Diana will continue to seek to maximize value on behalf of all shareholders. We are grateful to Genco shareholders for engaging in thoughtful discourse with us over the past several months, and we encourage all shareholders to join us in continuing to hold the Board and management team accountable. Our door remains open, and we are eager and available to engage with respect to the attractive offer we have proposed."

Information Regarding the Offer

On May 4, 2026, Diana commenced a tender 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 increased the offer price from $23.50 per share in cash to $24.80 per share in cash. On June 17, 2026, Diana increased its Offer to reflect an implied value of $27.34 per Genco share comprised of $24.80 in cash and one Diana share with an implied value of $2.54 based on Diana's 30-day VWAP as of June 16, 2026. To the extent that Genco declares a cash dividend or other distribution on the Genco shares, the cash component of the offer price will be reduced by the amount payable per share. Diana intends to file with the SEC an amended tender offer statement on Schedule TO and a registration statement on Form F-4 reflecting the terms of its revised Offer. These materials, as may be amended from time to time, will contain important information, including the terms and conditions of the revised Offer. Shareholders of Genco are strongly advised to read Diana's amended tender offer statement, registration statement and other offer documents as they become available because they will contain important information regarding the revised offer. Diana's tender offer statement, offer to purchase and other offer documents, when filed, will be available at no charge on the SEC's website at www.sec.gov.

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, (v) Diana's registration statement on Form F-4 being declared effective by the SEC, 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 consideration 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 and one share of Diana. Importantly, shareholders who tender in the Offer may receive their consideration sooner than those whose shares are acquired in the second-step merger.

Revised Offer Documents will be mailed to Genco shareholders.
