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. Coastlands Capital LP filed Nov 6, 2026 Schedule 13G passive filing 17.5%
  2. Renaissance Technologies LLC filed Aug 13, 2026 Schedule 13G passive 98,625 shares filing 5.13%
