As of Q2 2026, 37 SEC-registered investment managers reported holding AMTM (AMENTUM HOLDINGS INC) in their latest 13F filings, with a combined reported value of $1.55B across 75.58M shares. That is +7.9% by share count (+5.51M shares) versus the previous quarter, while reported value moved -14.7%. Ownership is concentrated: the five largest holders account for 71.8% of reported value and the top ten for 85.7%.

Compared with the prior quarter, 1 opened new positions, 20 added to existing stakes, 13 trimmed, 3 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

AMTM is classified in the Consumer Discretionary sector.

All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
