The largest dollar stake in AMG belongs to BlackRock, Inc., but the position matters far more to Kiltearn Partners LLP, who has 15.2% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
