Company positioning and business
Affiliated Managers Group, Inc. (AMG) is an American financial services firm founded in 1993 and headquartered in West Palm Beach, Florida. The company's stock trades on the New York Stock Exchange under the symbol AMG, and is listed on the S&P 400 for mid-size American firms. [3]
AMG operates as a strategic partner to independent investment management firms globally, with equity stakes in a number of partner-owned traditional investment managers, hedge funds, and specialized private equity firms which it calls “Affiliates.” The company has principal offices in West Palm Beach, Florida; Prides Crossing, Massachusetts; Stamford, Connecticut; and London, United Kingdom. The company was founded in December 1993 by William J. Nutt in Boston, Massachusetts, as a privately owned company with initial backing from TA Associates; its initial public offering on the New York Stock Exchange occurred in November 1997. Today, AMG's Affiliates manage $651 billion in assets in aggregate. [3]
AMG's strategy is to generate value by investing in an array of independent firms and supporting their long-term growth, through an approach in which significant equity ownership is retained by the management partners of each Affiliate, and each Affiliate operates and invests autonomously from AMG and from other Affiliates. The Affiliate principals’ ‘skin in the game’ incentivizes them to maximize long-term value creation, and their retained investment independence preserves the entrepreneurial cultures of each Affiliate firm.
