% of shares outstanding not shown: no SEC cover-page share count falls within 120 days of the 2026-Q1 quarter end, so any percentage would rest on a count that cannot speak for this quarter. Holder share counts are shown as filed.
Crowding percentile lands with its cohort — the cohort is size-matched, so it needs a market cap for GRDN in the served universe — that lands with the next screener build.
