"It is an honor to be appointed CFO, particularly at this exciting time of growth and positive momentum for our Company," said Mr. Sartori.

This is an incredible business with an exceptional team, and I look forward to playing an even greater role in executing our strategy and generating value for shareholders."

"On behalf of everyone at Dynex, I'd like to thank Rob for his many contributions to our Company," added Byron L. Boston, Chairman and Co-Chief Executive Officer. "Rob has been an important part of Dynex's exponential growth over the last few years. He has instilled professionalism, rigor and transparency in our financial reporting processes, helping Dynex cement its status as one of the best-performing mortgage REITs this decade. We are grateful for his leadership and expertise."

"It has been a privilege to serve as Dynex's CFO and play my part in executing on our proven strategy that delivers top-tier returns," said Mr. Colligan. "I am proud of the track record of dividend payments to shareholders and the growth in our capital base, and I look forward to seeing all that the team accomplishes in the years ahead. Mike has done a spectacular job growing the capital base of the Company and I am personally excited for him in his new role."

To facilitate a smooth transition of roles and responsibilities, Mr. Colligan has agreed to remain with the Company to serve in an advisory role through May 1, 2026. Mr. Colligan's departure is unrelated to the Company's financial reporting or controls.
