“Upon completing fifteen rewarding years of service on AMG’s Board of Directors, I have decided that now is the right time to retire,” said Mr. Churchill. “This decision comes after much reflection and with a deep sense of gratitude for the experience and professional camaraderie I have enjoyed; serving on AMG’s Board has been one of the most meaningful chapters of my professional life. I am particularly proud of my working relationship with Jay Horgen and the entire management team over the years, over the course of which AMG has grown and developed significantly, and the organization has evolved in many positive ways. I have had the privilege of working alongside many wonderful colleagues on the Board whose dedication and commitment I have found truly inspiring.”

“Over the course of his fifteen-year tenure, Dwight has played a variety of leadership roles, including Chair of our Audit Committee, Chair of the Board, and most recently, as interim Chair again, and AMG and our shareholders have deeply benefited from his leadership and insight; I am personally grateful for our long working relationship and Dwight’s leadership and dedication to AMG; he will be missed,” said Jay C.
