Affiliated Managers Group, Inc. (AMG) is a global partner to independent investment firms, holding meaningful equity stakes in “Affiliates” while leaving them operationally autonomous. As of December 31, 2025, Affiliates managed approximately $813 billion across private markets, liquid alternatives, and differentiated long-only strategies.

Private markets assets were about $146 billion and liquid alternatives $227 billion, with the balance in equities, multi-asset, and fixed income.

AMG reports $2.7 billion of debt, significant intangibles of $4.2 billion, equity-method investments of $2.9 billion, and unfunded GP/seed commitments of $285 million, alongside substantial regulatory, reputational, and operational risk factors.

Affiliated Managers Group reported that Thomas M. Wojcik will step down as President and Chief Operating Officer effective March 6, 2026. His responsibilities will be reassigned to other senior leaders, rather than filled by a single replacement role.

In connection with his departure and continued service through the Departure Date, Wojcik is scheduled to receive $5,025,000 in cash payments in 2026, contingent on signing and re-signing a separation and release agreement covering non-competition, non-solicitation, confidentiality, and related terms. If he satisfactorily fulfills ongoing obligations to the company through early 2027, including limits on competitive activity, he will receive an additional $11,050,000 cash payment in the first quarter of 2027.

Wojcik will forgo any long-term or short-term incentive compensation for performance years 2025 and 2026, and all of his unvested equity awards will be cancelled on the Departure Date, meaning he will not retain future equity-based upside from those awards.

Affiliated Managers Group, Inc. completed an offering of $425,000,000 aggregate principal amount of its 5.500% Senior Notes due 2036. The unsecured, unsubordinated notes mature on February 15, 2036 and pay interest at 5.500% per year, with payments on February 15 and August 15 each year, starting August 15, 2026. The company may redeem the notes at any time, in whole or in part, at a make-whole redemption price plus accrued and unpaid interest.

The company intends to use the net proceeds mainly to redeem in full and settle in cash its 5.15% Convertible Trust Preferred Securities due 2037 of AMG Capital Trust II, with any remaining proceeds expected to be used for general corporate purposes.
