Going-concern doubt
— flagged Aug 13, 2026
Substantial doubt about the company's ability to continue as a going concern.
“The Company's liquidity condition and mandatory liquidation within one year of the issuance of these unaudited condensed financial statements raise substantial doubt about the Company's ability to continue as a going concern. Management plans to address this uncertainty through a Business Combination.”View the 10-Q filed Aug 13, 2026

Every disclosed holder of ONCH 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 ONCH
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) | 18,658,674 | 86.53% |
| Insiders (Forms 3, 4, 5) | 0 | 0.00% |
| 13D/G-only blocks | 6,403,506 | 29.70% |
| Remaining | 3,499,680 | -16.23% |
| Registered funds (N-PORT, not summed) | 342,284 | 1.59% |
Shares outstanding: 21,562,500, 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.
