HACQU · HCM IV Acquisition Corp. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“The Company lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the date of the issuance of the financial statements. This condition raises substantial doubt about the Company's ability to continue as a going concern. Management plans to address this uncertainty through the closing of the initial Business Combination. There is no assurance that the Company's plans to raise capital will be successful. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.”View the 10-Q filed Aug 13, 2026
Every disclosed holder of HACQU 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.

| Holder group | Shares | % Out |
|---|---|---|
| Institutional (13F) | 5,390,505 | — |
| Insiders (Forms 3, 4, 5) | 0 | — |
| 13D/G-only blocks | 0 | — |
| Registered funds (N-PORT, not summed) | 50,000 | — |
% 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.
