Full-market context: across ALL 13F filers (SEC structured data, Q1 2026): 33 holders, 18.87M shares, $16.75M reported. This is a different, older period than the tracked-universe figures above and the two are never mixed.
Frequently co-owned
What else this security's tracked holders most often hold: shared-ownership counts, not fundamental relationships.
Provenance: Ownership from parsed 13F common-stock positions (tracked universe, comparable sets for changes); insider rows from Forms 3/4/5; stakes from Schedules 13D/13G; every filing links to its original on SEC EDGAR.
