Diana Shipping announces internal leadership reshuffle, keeping continuity in key roles.

The company discloses a set of coordinated officer resignations and appointments effective January 1, 2026. Anastasios Margaronis will step down as President and Executive Committee member, while Ioannis Zafirakis resigns several officer positions but is simultaneously appointed as President. This indicates a redistribution of responsibilities rather than a full leadership departure.

New appointments include Evangelos Sfakiotakis as Chief Technical Investment Officer, Margarita Veniou as Secretary and Corporate Contact, and Maria Dede as Treasurer. The detailed background for Mr. Sfakiotakis, including his experience overseeing fleets of more than 30 bulk carriers and prior senior roles at Pavimar S.A. and TMS Tankers Ltd, underscores relevant operational and technical expertise.

The report also states that the information is incorporated by reference into existing Form F-3 registration statements, linking these governance changes to the company’s broader capital markets disclosure framework. Overall, this appears as an internal realignment of executive duties, with the actual impact depending on how the new structure supports day-to-day operations and strategic decisions disclosed in future reports.
