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. Pivotal bioVenture Partners Fund II, L.P. filed Aug 20, 2026 Schedule 13G passive filing 5.5%
  2. Catalyst4, Inc. filed Aug 18, 2026 Schedule 13D/A may seek influence 27,536,011 shares filing 49.9%
  3. Catalyst4, Inc. filed Aug 3, 2026 Schedule 13D/A may seek influence 20,906,689 shares filing 47.9%
  4. Novo Holdings A/S filed Jul 31, 2026 Schedule 13D/A may seek influence 2,086,622 shares filing 4.9%
