BURU · Nuburu, Inc. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“The Company has identified conditions that raise substantial doubt about its ability to continue as a going concern within 12 months from the issuance of these condensed consolidated financial statements, including historical operating losses, negative cash flows from operations, significant debt service obligations, and reliance on external financing. Management believes that the actions described above could significantly reduce the conditions that raise substantial doubt about the Company's ability to continue as a going concern. However, substantial doubt about the Company's ability to continue as a going concern remains.”View the 10-Q filed Aug 14, 2026
Every disclosed holder of BURU in one list: 13F institutions, Schedule 13D and 13G filers, insiders (Forms 3, 4 and 5) and registered funds, each from its own latest filing. Holders nest by CIK and SEC reporting links, never by name, and each is summed once.
Who Owns BURU
13F quarter Sep 30, 2026, combined view: filers that have not filed yet carry their Jun 30, 2026 positionsNo chart: the summed disclosures exceed shares outstanding, so they are not parts of one whole.
| Holder group | Shares | % Out |
|---|---|---|
| Institutional (13F) | 286,540 | 123.74% |
| Insiders (Forms 3, 4, 5) | 0 | 0.00% |
| 13D/G-only blocks | 2,933,478 | 1266.84% |
| Remaining | 2,988,459 | -1290.58% |
| Registered funds (N-PORT, not summed) | 188,606 | 81.45% |
Shares outstanding: 231,559, the issuer's latest cover-page count restated onto today's split basis.
Insiders are listed but not summed: the issuer has more than one class of common stock and Forms 3, 4 and 5 report one issuer-wide balance across them.
Remaining is negative: the summed disclosures exceed shares outstanding, as when filings are dated at different times or holders that do not disclose their links count the same shares. It is flagged, not clipped.
13D/G-only counts each filer's latest 13D or 13G that no 13F report of the listing contains, that names no 13F filer and that no counted insider files. Funds are never summed: their shares sit inside their advisers' 13F reports.

Shares are restated onto today's split basis. Change compares each row with the same holder's previous filing in the same source; a dash means there is none to compare. Nested 13D/G, insider and fund rows are not summed, since a 13F report already holds them.
