**Gladstone Commercial Corporation Announces Strategic Succession Plan** 

McLean, VA, March 23, 2026: <u>Gladstone Commercial Corporation</u> (Nasdaq: GOOD) (the "Company") today announced several executive officer appointments in connection with the Company's strategic succession plan.

David Gladstone has stepped down as the Company's Chief Executive Officer ("CEO"), effective immediately; however, he will remain as the Company's Chairman of the Board of Directors, a member of the Company's investment committee, and also continue as Chairman, CEO, and President of the Company's affiliated investment adviser, Gladstone Management Corporation. Arthur "Buzz" Cooper, the Company's President since 2022 who joined the Gladstone organization in its founding year (2001), has succeeded Mr. Gladstone as CEO and will function in the dual role of CEO and President. John Sateri, a twenty-year veteran at Gladstone and a current member of the Company's investment committee, has been appointed Chief Investment Officer.

Gary Gerson, Chief Financial Officer and Assistant Treasurer of the Company since 2021 and who previously served as Treasurer from 2006-2012, has also been named Executive Vice President of the Company and will continue to serve in all three roles. Ryan Carter, a current Managing Director of the Company since 2021, has also been elevated to Executive Vice President.

These promotions reflect the strength and depth of the management team at the Company.

Today's announcement highlights Mr. Gladstone's long tenure with the Company, as its founder, Chairman, and CEO, beginning in 2003, and building it from its IPO to a real estate investment trust ("REIT") with over 150 properties, as of December 31, 2025, that invests primarily in single-tenant net leased industrial properties nationwide and is diversified across tenants, industries, and geographies. In his role, Mr. Gladstone has overseen enormous growth and has set the Company on a path for continued success.

Today's appointments are the result of a comprehensive strategic succession plan process designed to ensure long-term continuity, stability, and strategic alignment and reflect the Board's confidence in current management's ability to lead the Company through its continued growth. This succession plan will also separate the Chairman and CEO roles at the Company, further aligning with best practices for corporate governance and oversight.

------

Mr. Gladstone, commented, "Gladstone Commercial is our first Gladstone REIT established in 2003. I am grateful for the opportunity to lead such an extraordinary team over the past twenty-three years and am confident that our new executive leadership team will lead the Company through many decades to come. It is proud moment to see the Gladstone family of funds celebrating its silver anniversary, our twenty-fifth year in business."

Walter Wilkinson, Lead Independent Director of the Board, commented, "As the visionary founder of the Gladstone family of funds and more than twenty-three years as CEO of Gladstone Commercial, David has built this Company from its IPO to the REIT it is today. The Board and I extend our deep appreciation and gratitude for David's extraordinary leadership."

Mr. Cooper added, "As I take on this new additional role as the Company's CEO, I am grateful for David's mentorship and friendship of over forty years. We have an extremely talented team, and I am excited to continue building on our strong foundation and growth with the elevation of Gary Gerson and Ryan Carter to their new additional roles as Executive Vice Presidents."
