TACO · Berto Acquisition Corp. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“In connection with the Company's assessment of going concern considerations in accordance with FASB ASC 205-40, "Presentation of Financial Statements – Going Concern, Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern", as of June 30, 2026, management has determined that the Company's liquidity, mandatory liquidation, should a business combination not occur, and potential subsequent dissolution raise substantial doubt about its ability to continue as a going concern through the earlier of the liquidation date of May 1, 2027 or the completion of the Initial Business Combination.”View the 10-Q filed Aug 14, 2026
Every disclosed holder of TACO 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 TACO
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) | 40,737,246 | 108.58% |
| Insiders (Forms 3, 4, 5) | 5,402,700 | 14.40% |
| 13D/G-only blocks | 5,089,500 | 13.57% |
| Remaining | 13,710,696 | -36.54% |
| Registered funds (N-PORT, not summed) | 689,442 | 1.84% |
Shares outstanding: 37,518,750, the issuer's latest cover-page count restated onto today's split basis.
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.
