“Safe Harbor” Statement under the Private Securities Litigation Reform Act
of 1995 This communication contains forward-looking statements made pursuant to the saafe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements 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 communication 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 Securities and Exchange Commission, 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. We do not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information,
future events or otherwise. 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. Important Additional Information and Where to Find
