Full-market context: across ALL 13F filers (SEC structured data, Q1 2026): 206 holders, 83.68M shares, $1.67B reported. This is a different, older period than the tracked-universe figures above and the two are never mixed.
Frequently co-owned

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.
