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. BANK OF AMERICA CORP /DE/ filed Oct 28, 2026 Schedule 13G/A passive 357,318 shares filing 2.4%
  2. Perceptive Advisors LLC filed Aug 14, 2026 Schedule 13G/A passive filing 9.99%
  3. VIKING GLOBAL INVESTORS LP filed Aug 14, 2026 Schedule 13G/A passive filing 9.3%
