Large holders · SEC Schedules 13D and 13G

Five percent and over

Anyone who comes to hold more than 5% of a company's voting shares must tell the SEC. A Schedule 13D is filed by a holder who may seek to influence the company; a 13G by one who states it is a passive investor. An amendment updates an earlier filing, and a stake reported as 0% means the holder says it has sold all, or nearly all, of its shares. Every recent 13D and 13G

  1. Citadel Securities GP LLC filed Oct 15, 2026 Schedule 13G/A passive filing 6%
  2. G1 Execution Services, LLC filed Aug 14, 2026 Schedule 13G/A passive filing 7%
