Reported totals, quarter ended 2026-06-30

Shares outstanding check: 67,024,154 shares reported by the issuer (SEC XBRL, period ended 2026-06-30). Reported 13F shares equal 103.3% of that figure. This page passed the publication sanity gate before listing.
RPD in this quarter's filings
Concentration check: the largest reported position, BlackRock, Inc. with 9,012,619 shares, is 13.0% of all shares reported for RPD this quarter. The five largest reporting managers together account for 38.4% 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 fell by 5 versus the quarter ended 2026-03-31, and reported shares moved +13.03% (+7,981,283 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 103.3% of the issuer share count used at the publication gate (67,024,154 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.

What this page is and is not
Form 13F reports are quarterly holdings snapshots. 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.
