Large holders from 13D/13G (latest per reporting person, last 2 years)
Filed when a holder crosses 5% or changes materially, so often more current than the quarter-end 13F. Percentages are the filer's own, against the share count they used.
| Reporting person | Form | Filed | Event | Shares | % of class |
|---|---|---|---|---|---|
| Gareth Sheridan | SCHEDULE 13D/A | 2026-09-15 | 2021-09-29 | 1,786,000 | 14.2% |
| Serguei Melnik | SCHEDULE 13D | 2025-03-13 | 2021-09-29 | 1,071,418 | 9.39% |
Source: SEC Form 13F-HR information tables for the quarter ending 2026-06-30 (filed within 45 days of quarter end; amendments applied; values normalised to dollars), the share count from the company's latest 10-K/10-Q XBRL cover page, and Schedule 13D/13G filings. Each row is a legal 13F filer as filed — related entities (e.g. Vanguard's advisers) are not merged. Retail brokerage accounts are not reported on 13F, so the remainder is mostly retail and insiders.
