DESCRIPTION OF COMMON STOCK

The following is a description of the material terms and provisions of our common stock. It may not contain all the information that is
important to you. Therefore, you should read our charter and by-laws for additional information related to our common stock.

General

Under our charter, we are
authorized to issue up to 150,000,000 shares of common stock, par value $0.01 per share, and up to 3,000,000 shares of Class B non-voting common stock, par value $0.01 per share. Under Delaware law,
stockholders generally are not responsible for our debts or obligations. As of December 31, 2024, we had 29,594,990 shares of common stock outstanding, an additional 28,924,054 shares of common stock were held in the Company’s treasury,
and there were no shares of Class B non-voting common stock outstanding. All shares of common stock will, when issued, be duly authorized, fully paid and nonassessable. Our common stock is listed on the
NYSE under the symbol “AMG.”

Dividends

Subject to preferential rights of any other class or series of stock, holders of common stock and Class B
non-voting common stock may receive dividends out of assets that we can legally use to pay dividends, when, as, and if they are declared by our board of directors, with each share of common stock and each
share of Class B non-voting common stock sharing equally in such dividends (with each share of Class B non-voting common stock being equal to the number of
shares of common stock into which it would then be convertible). If dividends are declared that are payable in shares of common stock or shares of Class B non-voting common stock, such dividends will be
declared payable at the same rate in both classes of stock and the dividends payable in shares of common stock will be payable to the holders of shares of common stock, and the dividends payable in shares of Class B non-voting common stock will be payable to the holders of shares of Class B non-voting common stock.

Voting Rights

Holders of common stock
will have the exclusive power to vote on all matters presented to our stockholders, including the election of directors, except as otherwise required by Delaware law or as provided with
