Shares outstanding check: 48,885,358 shares reported by the issuer (SEC XBRL, period ended 2025-12-31). Reported 13F shares equal 65.8% of that figure. This page passed the publication sanity gate before listing.
ASTH in this quarter's filings
Concentration check: the largest reported position, BlackRock, Inc. with 6,899,990 shares, is 21.5% of all shares reported for ASTH this quarter. The five largest reporting managers together account for 46.1% 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 rose by 38 versus the quarter ended 2026-03-31, and reported shares moved +7.47% (+2,235,225 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 65.8% of the issuer share count used at the publication gate (48,885,358 shares, issuer period ended 2025-12-31). 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.
