What Affiliated Managers Group does

Affiliated Managers Group, Inc. (NYSE: AMG), founded in December 1993 by William J. Nutt in Boston, Massachusetts, is a strategic partner and minority equity investor in approximately 40 independent, boutique investment management firms ("Affiliates"). AMG holds long-duration minority stakes — typically through structured partnerships that allow affiliates to maintain full operational independence — and supports them with growth capital, succession planning, product development, and global distribution. Affiliates collectively manage more than 500 investment strategies across equities, fixed income, alternatives, and multi-asset classes, with aggregate assets under management of approximately $882 billion as of March 31, 2026. AMG's two principal distribution platforms are a global institutional platform with offices in London (regional HQ), Tokyo, Sydney, Dubai, Stamford, and Singapore, and a U.S. wealth platform that reaches financial advisors and individual investors, including through AMG Distributors, Inc. (a FINRA member) and a new collaboration with Brown Brothers Harriman.

AMG generates revenue primarily through its proportional share of affiliate earnings, which derive from management fees (typically a percentage of AUM) and performance fees on affiliate strategies. Management-fee revenue is recurring in nature, and AMG has been deliberately shifting its mix toward alternatives — private markets, liquid alternatives, real assets, and private credit — which now generate approximately 60% of EBITDA and command higher fee margins than traditional long-only assets. Marquee affiliates include AQR Capital Management (liquid alternatives, tax-aware strategies), Pantheon (private equity, real assets, private credit), Yacktman Asset Management (value equity), GW&K Investment Management, Harding Loevner (global equity), and TimesSquare Capital Management (growth equity), with newer affiliates in renewable energy (Qualitas Energy), real estate (NorthBridge Partners, HighBrook Investors), private equity (Montefiore Investment), and multi-strategy (Verition Fund Management).

AMG's go-to-market is partnership-driven: the company does not sell proprietary products directly to retail consumers but instead deploys capital into Affiliates and distributes their strategies through its institutional and wealth channels. Pricing is negotiated at the affiliate level and varies by strategy, vehicle, and client type. Recent operating performance is strong, with full-year 2025 revenue of approximately $2.07 billion, adjusted EBITDA of approximately $1.1 billion (up 11% YoY), economic EPS of $26.05 (up 22%), and record net client cash inflows of $29 billion. Q1 2026 results accelerated further with revenue of $544.9 million, adjusted EBITDA of $317.3 million (up 39% YoY), economic EPS of $8.23 (up 58% YoY), and net client cash flows exceeding $22 billion. AMG is publicly listed on NYSE since 1997, has 1,001-5,000 employees, and is led by President and CEO Jay C. Horgen (CEO since 2019) and CFO Dava Ritchea (joined 2024).

Revenue model

1. Advisory and Management Fees: AMG generates revenue primarily through ownership interests in its affiliate investment management firms. Affiliates earn management fees (typically a percentage of assets under management) and, in some cases, performance fees. AMG's share of these earnings flows through as revenue, driven by the AUM and performance of its ~40 affiliate firms managing 500+ strategies across equities, fixed income, alternatives, and multi-asset classes. The company has been strategically shifting toward alternatives, which now contribute approximately 55-60% of EBITDA.
2. Alternative Asset Management: AMG's affiliates manage alternative strategies including private markets, liquid alternatives, real assets, and private credit. These alternative strategies generate higher fee margins than traditional passive assets, with alternatives contributing approximately 60% of EBITDA as of Q1 2026. The company added approximately $97 billion in alternative AUM in 2025, representing a 35% increase.
