On June 12, 2026, Genco Shipping & Trading Limited (“Genco”) sent an e-mail to shareholders. A copy of the e-mail can be found below:

E-mail to Shareholders

Dear Genco Shareholders,

We are reaching out to you directly as you need to take action today. Genco’s highly qualified Board continues to act in the best interests of all Genco shareholders and is successfully executing its Comprehensive Value Strategy, which has delivered $7.16 per share in dividends to shareholders and generated outsized shareholder returns of 210%.¹ We believe Genco will deliver compelling dividends and superior value to shareholders in a strengthening drybulk market.

Diana Shipping inc. is trying to take over Genco on the cheap through a proxy fight to replace some of Genco’s board members. Diana has also launched a tender offer at an inadequate $24.80 price, which is below Genco’s underlying net asset value (NAV); and does not provide a control premium.

Don’t let Diana prevent you from realizing the full upside potential of your Genco investment. Do not tender your shares into Diana’s offer. Vote today:

“FOR”

The reelection of ALL of Genco’s highly qualified nominees

•

Paramita Das, Kathleen C. Haines, Basil G. Mavroleon, Karin Y. Orsel, Arthur L. Regan and John C. Wobensmith

“FOR”

The Board’s recommendations on other proposals

•

Proposals 2, 3, 4 and 5

“WITHHOLD”

Forward-Looking Statements

This communication contains statements that may constitute forward-looking statements. These statements include, but are not limited to: statements related to the Company’s views and expectations regarding Diana Shipping Inc.’s unsolicited tender offer; any statements relating to the plans, strategies and objectives of management or the Company’s Board for future operations and activities; any statements concerning the expected development, performance, market share or competitive performance relating to products or services; any statements regarding current or future macroeconomic trends or events and the impact of those trends and events on the Company and its financial performance; and any statements of assumptions underlying any of the foregoing. Forward-looking statements can be identified by the fact that they do not relate strictly to historic or current facts and often use words such as “anticipate,” “budget,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” and other words and terms of similar meaning in connection with a discussion of potential future events, circumstances or future operating or financial performance. These forward-looking statements are based on our management’s current expectations and observations. Included among the factors that, in our view, could cause actual results to differ materially from the forward looking statements contained in this release are the following: (i) the Company’s plans and objectives for future operations; (ii) that any transaction based on Diana’s non-binding indicative proposal or otherwise may not be consummated at all; (iii) the ability of Genco and its shareholders to recognize the anticipated benefits of any such transaction; (iv) the exercise of the discretion of our Board regarding the declaration of dividends, including without limitation the amount that our Board determines to set aside for reserves under our dividend policy; and (v) other factors listed from time to time in our filings with the SEC, including, without limitation, our Annual Report on Form 10-K for the year ended December 31, 2025 and subsequent reports on Form 8-K and Form 10-Q. Our ability to pay dividends in any

period will depend upon various factors, including the limitations under any credit agreements to which we may be a party, applicable provisions of Marshall Islands law and the final determination by the Board of Directors each quarter after its review of our financial performance, market developments, and the best interests of the Company and its shareholders. The timing and amount of dividends, if any, could also be affected by factors affecting cash flows, results of operations, required capital expenditures, or reserves. As a result, the amount of dividends actually paid may vary. In addition, the forward-looking statements included in this communication represent the Company’s views as of the date of this communication and these views could change. However, while the Company may elect to update these forward-looking statements at some point, the Company specifically disclaims any obligation to do so, other than as required by federal securities laws. These forward-looking statements should not be relied upon as representing the Company’s views as of any date subsequent to the date of this communication.
