ACGC · ACP Holdings Acquisition Corp. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“Management has determined that the Company currently lacks the liquidity it needs to sustain operations for a reasonable period of time, which is considered to be at least one year from the date that the accompanying unaudited condensed financial statements are issued as it expects to continue to incur significant costs in pursuit of its acquisition plans. In addition, Management has determined that if the Company is unable to complete an initial Business Combination within the Completion Window, then the Company will cease all operations except for the purpose of liquidating. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management plans to consummate an initial Business Combination prior to the end of the Completion Window. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after October 8, 2027 (18 months from the closing of the Initial Public Offering), the end of the combination period. There can be no assurance that the Company's plans to raise capital or to consummate an initial Business Combination will be successful.”View the 10-Q filed Aug 12, 2026

Shares outstanding: 29,100,467, 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.
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.
