Across its top 20 institutional holders, ATI's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 43/100).
ATI ranks #665 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
ATI is a top-conviction position for Dendur Capital LP — at 10.4% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in ATI belongs to BlackRock, Inc., but the position matters far more to Dendur Capital LP, who has 10.4% 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.
BlackRock has added to its ATI position for two straight quarters, increasing it by $2.0B to reach $3.7B today.
Capital International Investors has trimmed its ATI position for two straight quarters, cutting it by $1.2B while still holding $733.2M.

Q2 2026
Top 5 Institutional Movers
ATI does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-06-30 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.
