Affiliated Managers Group, Inc. (AMG) announced on December 11, 2025, the successful completion of a $425 milliona issuance of 5.500% Senior Notes due 2036.

These notes are unsecured and unsubordinated obligations of the company, maturing on February 15, 2036, with semi-annual interest payments. The offering was conducted under a shelf registration statement and was supported by an underwriting agreement with BofA Securities, Citigroup Global Markets, and Wells Fargo Securities.

Any remaining proceeds are earmarked for general corporate purposes. This transaction effectively refinances a portion of AMG's outstanding debt, potentially impacting its interest expense and capital structure.
