Mr. Healey said, "I have the utmost confidence in Nate's ability to lead AMG to the next stages of its success. Nate has been by my side as my partner since AMG's earliest days, and has been involved in every key strategic decision along the way. With his deep understanding of our Affiliate partnerships, proven experience in building our centralized global distribution platform from the ground up, and outstanding leadership across our business, he has made countless and tireless contributions to AMG's success, and is the ideal executive to lead the company forward. While I undergo treatment, I look forward to actively supporting Nate and the rest of our executive team."

Ryan, Lead Independent Director, said, "AMG is fortunate to have a deep bench of talent and a proven leader in Nate, who has the confidence of the Board to lead the Company forward following Sean's extraordinary leadership over the past two decades. Thoughtful, deliberate succession planning is at the very heart of AMG's business strategy and core philosophy, and this transition reflects the Board's long-standing framework – now we are executing on that plan. Alongside Sean, the other Directors and I are grateful for Nate's contributions to date and all of those that are to come."
