Dimensional Fund Advisors discloses 1.95% stake in AMG Critical Materials

A new Rule 8.3 filing shows Dimensional held 700,129 AMG Critical Materials shares on 15 July 2026 and bought 3,060 shares, while reporting no derivatives or related arrangements.

Fact Check
The primary Form 8.3 disclosure on GlobeNewswire directly confirms every element of the claim: Dimensional held 700,129 AMG Critical Materials shares (1.95%) on 15 July 2026, bought 3,060 shares, and reported no derivatives or related arrangements (no short positions, derivatives/options). The only minor omission in the claim is a 736-share transfer out, which does not contradict the claim's stated facts.
