Dear Shareholder,

You are a significant holder in one or more of the AMG Funds and we need your help! The combined Special Meeting of Shareholders of the AMG Funds initially held on October 10, 2023, has been adjourned with respect to one or more proposals to October 31, 2023, at 3:00 pm Eastern time due to a lack of voter participation.

It is important that we receive your vote response to proceed with the important business of the Funds. To date, the Funds have not received the minimum number of shareholder votes required by law to proceed with certain of their important proposals. We are reaching out to respectfully reiterate how critical it is for you to vote for your shares, and we may not be able to hold the meeting without your vote.

PLEASE help us to avoid the cost of additional follow-up messages by casting your vote today. Your participation matters and your vote will make a difference.

The reason for the adjourned Combined Special Meeting is to ask shareholders to approve the amendment of certain fundamental investment restrictions of each applicable Fund. Such proposals are further discussed in the proxy statement that was first mailed to shareholders on or about September 1, 2023 (the “Proxy Statement”). The Boards of Trustees of the Trusts recommend that you vote “FOR” all proposals. Important details are included in the Proxy Statement which can be found at vote.proxyonline.com/AMG/docs/AMGFunds2023.pdf.

If you have any proxy-related questions or would like to cast your vote by phone, call (866) 521-4487 for assistance. Representatives are available Monday through Friday, 9 a.m. to 10 p.m. Eastern time. This letter is first being sent to shareholders on October 18, 2023.

We very much appreciate your attention to this matter.

Sincerely,

/s/ Keitha L. Kinne

Keitha L. Kinne

President
