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. Millennium Management LLC filed Oct 13, 2026 Schedule 13G/A passive filing 0.1%
  2. Dimensional Fund Advisors LP filed Oct 8, 2026 Schedule 13G passive filing 5.2%
  3. GAGNON SECURITIES LLC filed Aug 27, 2026 Schedule 13G passive filing 2.9%
