DIANA SHIPPING INC. ASKS: WHY IS GENCO SO AFRAID OF DIANA’S TENDER OFFER?

The Answer: Because the Genco Board Can’t Take the Heat That Comes with Shareholders Expressing Their Views

Genco Board Has Resorted to Arguing Petty Technicalities Instead of Engaging with Diana

Keeps Making Hollow Claim That Shareholders Will Only Receive $24.80 Per Share if They Tender – The Truth is That Genco Shareholders Will Receive Nothing Because the Genco Board Continues to Maintain Its Poison Pill and Refuses to Negotiate a Value Creating Transaction

Diana’s Tender Offer Provides Shareholders with a Golden Opportunity to Deliver a Clear Message to the Genco Board That They Should Stop Stalling and Start Negotiating Based on Diana’s Latest Proposal:

$27.34 Per Share, Comprised of $24.80 in Cash and One Diana Share

Athens, Greece – July 8, 2026 – 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 asked Genco shareholders to consider a very simple question:

Why is Genco so afraid of Diana’s tender offer?

The answer is very simple: the Genco Board of Directors (the “Genco Board") knows very well that as more shares are tendered, the Genco Board runs out of excuses and becomes subject to more pressure to negotiate a transaction based on Diana’s increased proposal 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. That offer was delivered three weeks ago, and the Genco Board has done nothing but delay and make excuses. Stated otherwise, shareholders’ tendering into the tender offer is an indictment of the Genco Board’s complete failure to fulfill their fiduciary duty to engage with Diana in any way regarding a proposed transaction that would deliver premium value.

Instead, Genco has resorted to arguing technicalities. They shamefully tell their shareholders: “If you tender your shares into the tender offer, you would only receive $24.80 per share in cash, assuming the many conditions are met.” What Genco really should tell their shareholders is that if they tender their shares, they will receive nothing. This unfortunate circumstance is due to the Genco’s Board’s insistence on maintaining its poison pill – which prevents Diana from completing a transaction – and refusing to negotiate.

The reality is as follows:

This transaction cannot be completed through a tender offer alone – it will only become reality in a negotiation. That said, Diana’s tender offer is a strong mechanism for Genco shareholders to deliver a powerful message to the Board that was re-elected to serve the interests of all Genco shareholders. That message is to come to the table and negotiate a transaction with Diana on the basis of the latest proposal.

The Genco Board has in its hands a highly attractive offer that deserves a good faith dialogue between Diana, Genco and their respective advisors. For seven months, the Genco Board has gone to extraordinary lengths to avoid this conversation, but now is the time for them to listen to their shareholders, stop stalling and engage with a party that is prepared to pay Genco shareholders full value for their shares at a high-point in shipping cycle. The Genco Board should not let this opportunity slip away.

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.

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.
