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. ARK Investment Management LLC filed Nov 6, 2026 Schedule 13G/A passive filing 4.91%
  2. Bradley A. Keywell filed Oct 28, 2026 Schedule 13G/A passive filing 3.46%
