ONCHU · 1RT Acquisition Corp. · Shareholders & Ownership
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 ONCHU 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 ONCHU
13F quarter Jun 30, 2026; this listing alone: insiders and shares outstanding are issuer-wide, so they are left outNo chart: shares outstanding cannot be set against these holders.
| Holder group | Shares | % Out |
|---|---|---|
| Institutional (13F) | 3,156,152 | — |
| Insiders (Forms 3, 4, 5) | 0 | — |
| 13D/G-only blocks | 1,499,900 | — |
| Registered funds (N-PORT, not summed) | 0 | — |
% Out is unavailable: shares outstanding is an issuer-wide count, not one listing's.
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.
