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. Baker Bros. Advisors LP filed Nov 6, 2026 Schedule 13D/A may seek influence 2,330,144 shares filing 9.99%
  2. BlackRock, Inc. filed Jul 29, 2026 Schedule 13G/A passive 1,067,346 shares filing 4.6%
