AMBIQ MICRO INC

One holder's exit reshaped nearly the entire institutional picture at Ambiq Micro (AMBQ), a name with just 6 tracked holders and $15.2 million in reported value. Wasatch Advisors, previously the dominant owner, cut its stake by 68% in shares (from 254,303 to 81,559, a genuine $15.3 million real reduction) — the largest sale by far among the six holders. Moody Aldrich Partners arrived as a brand-new holder with an $7.19 million position, roughly comparable in scale to what Wasatch gave up. Perpetual Ltd also trimmed, cutting 48% of its shares (a real $704,457 reduction).
