Additional Proxy Soliciting Materials (Form DEFA14A)

Diana Shipping is trying to take over Genco on the cheap. To do so, Diana has launched a tender offer and proxy fight to replace the Genco Board with its own handpicked nominees

Diana's tender offer is at a price that is below the mean and median Net Asset Value that independent sell side analysts have estimated for Genco

Throughout their hostile campaign they have used discounted, outdated asset values and backward-looking financials instead of using current values

As a direct competitor to Genco, Diana knows the market is strengthening and values are rising across our industry

……so why use these figures as benchmarks?

Should Genco shareholders tender their shares at Diana's inadequate offer price?

Let's hear from Hamish Norton, President of Diana's transaction partner, Star Bulk…

"It's pretty hard to take over a shipping company at less than net asset value plus some premium. Because the Board is gonna demand basically at least liquidation value of the hard assets."¹

Diana is looking to replace Genco's highly-qualified directors with its own handpicked director nominees. Should there be changes to Genco's Board?

In the words of Ioannis Zafirakis, Director and President of Diana…

"Needless to say that Genco is a very well-run drybulk company" (Diana Shipping, Inc. Q2 2025 Earnings Call)

We believe Genco's share price and net asset value reflect the successful execution of the Company's Comprehensive Value Strategy in a strengthening drybulk market

Should Genco shareholders be excited about the opportunities to continue benefiting from a strengthening market?

Here's what Semiramis Paliou, Director and CEO of Diana, and Petros Pappas, CEO, Star Bulk, have said about the market environment….

"The usual seasonal slowdown in Q1 did not happen and the Capesize market had its best first quarter since 2010" (Diana Shipping, Inc. Q1 2026 Earnings Call)

"We're actually pretty bullish for the balance of this year, and we are bullish for next year as well" (Star Bulk Carriers Corp. Q1 2026 Earnings Call)

The answers for Genco shareholders are clear

Features Key Commentary from Diana and Star Bulk on Their Proposed Transaction and Market Conditions

The Video and Information on How to VOTE the WHITE Proxy Card

Are Available at www.GencoDrivesSuperiorReturns.com

NEW YORK, June 5, 2026 (GLOBE NEWSWIRE) -- Genco Shipping & Trading Limited (NYSE:GNK) ("Genco" or the "Company"), the largest U.S. headquartered drybulk shipowner focused on the global transportation of commodities, today shared a video highlighting key commentary from Diana Shipping Inc. ("Diana") and Star Bulk related to Diana's inadequate offer to acquire Genco on the cheap and the strength of the drybulk market.

Genco issued the following statement:

Genco is well positioned to deliver superior returns and value to shareholders in a strengthening drybulk market through the continued execution of its successful Comprehensive Value Strategy.

Diana is trying to take over Genco on the cheap. To do so, Diana has launched a tender offer at an inadequate price and proxy fight to replace the entire Genco Board with its own handpicked, unfit nominees.

As a competitor and a shipowner, Diana is well aware that its offer does not represent 1.0x net asset value (NAV). No matter the source - be it third-party sell-side analysts or VesselsValue.com - Diana's offer is at a discount to Genco's liquidation value and does not include a control premium.

Diana has continued to spread falsehoods and misleading statements throughout its campaign, which are designed to distract from the facts:

We encourage shareholders to ignore Diana's misinformation, and listen to what Diana and its transaction partner, Star Bulk, actually have to say about Genco, how to value an offer and the strength of the drybulk market: www.GencoDrivesSuperiorReturns.com/shareholder-resources.

Protect your investment - VOTE TODAY. The Board encourages shareholders to vote the WHITE proxy card today "FOR" Genco's highly qualified nominees, "WITHHOLD" on Diana's handpicked nominees and reject Diana's inadequate tender offer.
