11.1 Million, or 29.7% of Outstanding Shares Not Owned by Diana, Tendered into Offer as of July 10

Latest Direct Proposal of $27.34 Per Share, Comprised of $24.80 in Cash and One Diana Share, Remains on the Table

ATHENS, Greece, July 13, 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 announced that its tender offer to acquire all outstanding shares of Genco not already owned by Diana has been extended to July 24, 2026, at 5:00 p.m., New York City time. As of Friday, July 10, 2026, 11,081,926 shares – or 29.7% of the outstanding shares of Genco not owned by Diana – have been tendered into the offer. The shares tendered do not include any of the more than 14% of the outstanding shares of Genco owned by Diana.

Diana's increased offer made directly to the Genco Board to acquire the outstanding shares of Genco that it does not already own for $27.34 per share — comprised of $24.80 per share in cash plus one Diana share valued at $2.54 based on Diana's 30-day volume-weighted average price as of June 16, 2026 — remains on the table.

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

“We are pleased that additional shareholders have tendered their shares, but this transaction cannot move forward through a tender offer alone. To unlock the compelling value of this combination, both of our leadership teams and advisors must come together to negotiate in good faith, with a shared commitment to delivering full value for Genco shares at a high point in the shipping cycle.”

Diana's offer is supported by $1.412 billion in committed financing from six leading international banks with no financing condition. It 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 dry bulk asset values that are at or near 15-year highs.

The forward-looking statements in this press release and in other statements made by Diana or Star Bulk, as applicable, are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in Diana’s records, Genco’s public filings and disclosures and data available from third parties.

The forward-looking statements in this communication are based on current expectations, assumptions, and estimates, and are subject to numerous risks and uncertainties. These include, without limitation, risks relating to: (i) the possibility that the proposed transaction may not proceed; (ii) the ability to obtain regulatory or shareholder approvals, if required; (iii) the risk that Genco’s Board of Directors or management may continue to oppose the proposal or not respond to further attempted engagement by Diana; (iv) failure to realize anticipated benefits of the transaction; (v) changes in the financial or operating performance of Diana, Star Bulk or Genco; (vi) the possibility that shareholders of Genco will not elect to tender their shares of common stock of Genco in connection with the Offer (as defined below) or that the conditions to consummation of the Offer are not satisfied; and (vii) general economic, market, and industry conditions. These and other risks are described in documents filed by Diana with, or furnished by Diana to, the U.S. Securities and Exchange Commission (“SEC”), including its Annual Report on Form 20-F for the fiscal year ended December 31, 2025, and its other subsequent documents filed with, or furnished to, the SEC, and are described in documents filed by Genco with, or furnished by Genco to, the SEC, including its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, and its other subsequent documents filed with, or furnished to, the SEC. Diana undertakes no obligation to revise or update any forward-looking statement, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent required by law.

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. 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 increased offer made to the Genco Board reflecting 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. 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, and (v) other customary conditions. When Diana files an amended tender offer statement on Schedule TO and a registration statement on Form F-4 reflecting the terms of its increased offer, the Offer will be conditioned on Diana's registration statement on Form F-4 being declared effective by the SEC. 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 the same consideration. Importantly, shareholders who tender in the Offer may receive their consideration sooner than those whose shares are acquired in the second-step merger.
