APAM in this quarter's filings
Concentration check: the largest reported position, BlackRock, Inc. with 11,198,383 shares, is 16.1% of all shares reported for APAM this quarter. The five largest reporting managers together account for 38.2% of the reported total, so the headline total is spread across a broad manager base rather than a few holders.
Reported quarter-over-quarter change: the reporting-manager count was unchanged by 0 versus the quarter ended 2026-03-31, and reported shares moved +3.00% (+2,032,016 shares). That is a comparison of two filing snapshots, not a record of trades on any single day.
Shares-outstanding cross-check: reported 13F shares equal 85.9% of the issuer share count used at the publication gate (81,066,833 shares, issuer period ended 2026-06-30). The gate publishes a ticker only when that relationship is plausible; lending chains can push reported totals above a simple ownership share, which is why the figure is a sanity check and not an ownership percentage.

Managers file up to about 45 days after quarter-end, so these figures describe reported positions as of the quarter-end date, not holdings today. 13F lists reportable long positions from managers above the SEC reporting threshold and omits short positions entirely.
