On February 1, 2024, Thomas Guba, a member of the Board of Directors of ARMOUR Residential REIT, Inc. since 2009, resigned from the Board due to a worsening health condition, effective immediately. Mr. Guba has made a tremendous contribution to ARMOUR and his multiple decades of experience in the mortgage backed securities market has been a tremendous resource. Over his more than fifty year career, Mr. Guba has been deeply involved in the MBS market since its inception and has led the MBS Departments of a number of the leading firms in this area.

ARMOUR will miss his advice and counsel. Mr. Guba served on the Compensation Committee and Nominating and Corporate Governance Committee of the Board and as the lead independent director. The Board intends to evaluate the composition of such committees and the lead independent director position given Mr. Guba?s resignation and fill the vacancies on such committees and the lead independent director position in due course.
