Shares of Affiliated Managers Group (AMG) surged 5.64% in pre-market trading on Monday following the release of its third-quarter 2025 financial results that surpassed analyst expectations.

The asset management firm reported adjusted earnings per share of $6.10 for Q3, significantly higher than the $4.82 recorded in the same period last year and beating the FactSet analyst consensus estimate of $5.89. This represents a robust 27% year-over-year growth in economic earnings per share.

While AMG's revenue of $528 million fell short of the $544.6 million forecast by analysts, it still showed an improvement from $516.4 million in the prior-year quarter. The company's adjusted EBITDA of $250.9 million notably outperformed the expected $229.7 million.

Investors were particularly encouraged by AMG's strong net client cash inflows, which totaled approximately $9 billion for the quarter and $17 billion year-to-date. This growth was primarily driven by ongoing momentum in alternative strategies, reflecting the company's successful focus on increasing exposure to this sector.

Jay C. Horgen, CEO of AMG, highlighted the company's excellent results, citing a 17% growth in Adjusted EBITDA relative to the prior-year quarter. He also emphasized the positive impact of AMG's disciplined capital allocation strategy on earnings growth.
