Athens, Greece - 21 November 2025

Diana Shipping Inc. (NYSE: DSX), (the "Company"), a global shipping company specializing in the ownership and bareboat charter-in of dry bulk vessels, today announced that, through a separate wholly-owned subsidiary, it has entered into a time charter contract with SwissMarine Pte. Ltd., Singapore, for one of its Capesize dry bulk vessels, the m/v Seattle. The gross charter rate is US$24,500, minus a 5.00% commission paid to third parties, for a period until minimum May 1, 2027 up to maximum June 30, 2027. The charter is expected to commence on November 26, 2025. The m/v Seattle was chartered, as previously announced, to Solebay Shipping Cape Company Limited, Hong Kong, at a gross charter rate of US$17,500 per day, minus a 5.00% commission paid to third parties.

The "Seattle" is an 179,362 dwt Capesize bulk vessel built in 2011.

The employment of "Seattle" is anticipated to generate approximately US$12.62 million of gross revenue for the minimum scheduled period of the time charter.

The Company also announced that it has signed, through a limited partnership, a Memorandum of Agreement to sell to an unaffiliated third party, the 2016-built Ultramax dry bulk vessel m/v DSI Drammen, with delivery to the buyer latest by March 31, 2026, for a sale price of approximately US$26.40 million before commissions. The vessel has now been sold to a buyer, entirely unrelated to the previous one who failed to complete the transaction. The Company, through its wholly-owned subsidiaries, holds a 25% interest in the limited partnership, while the remaining 75% of the limited partnership is owned by Ecobulk AS, a Norwegian entity.
