AMGAMG

Affiliated Managers Group shares are higher after reporting Q1 2026 results showing record assets under management of $882 billion and more than $22 billion of positive net client cash flows. The company also posted Economic EPS of $8.23, up 58% year over year, and repurchased about $186 million of stock.

1. What’s moving the stock

Affiliated Managers Group (AMG) is moving higher today after releasing first-quarter 2026 results before the market open (May 1, 2026). Investors are keying on a strong profit print and unusually strong client demand signals: record AUM of $882 billion and record positive net client cash flows of more than $22 billion, alongside sharply higher year-over-year profitability metrics.

2. The key numbers investors are reacting to

AMG reported diluted EPS of $3.84 and Economic EPS of $8.23 for Q1 2026, with Economic EPS up 58% versus the prior year period. The quarter also showed record AUM of $882 billion (up from $712.2 billion a year earlier) and net client cash flows of about $22.5 billion, which management attributed to momentum in alternatives and private markets; adjusted EBITDA rose to $317.3 million (from $228.2 million a year earlier).

3. Capital allocation and strategy read-through

Beyond operating momentum, AMG highlighted continued capital returns, repurchasing roughly $186 million of common stock during the quarter. Management also pointed to continued investment activity and positioning toward secular-growth areas, citing the completion of its investment in BBH Credit Partners in January and a new partnership with HighBrook Investors in February, plus an additional investment in Garda Capital Partners.

4. What to watch next (today and beyond)

Focus is likely to turn to management’s conference call at 8:00 a.m. ET for detail on the mix of flows (especially alternatives/private markets), the durability of performance fees, and any updates on capital deployment priorities (buybacks vs. new affiliate investments). Investors will also watch whether the record AUM level translates into sustained fee growth in coming quarters, particularly given the quarter’s mixed top-line framing in some market recaps despite the EPS beat.
