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 |
|---|---|---|---|---|---|
| Advanced Drainage Systems Inc. Employee Stock Ownership Plan Trust | SCHEDULE 13G | 2026-02-13 | 2025-12-31 | 4,629,213 | 6% |
| GRACE & WHITE, INC | SCHEDULE 13G/A | 2026-01-27 | 2025-12-31 | 2,042,554 | 8.8% |
| Delaware Charter Guarantee & Trust Company dba Principal Trust Company as Directed Trustee for the Broadwind, Inc. Employees' 401(k) | SCHEDULE 13G | 2025-11-14 | 2025-11-14 | 1,669,405 | 7.3% |

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.
