Going-concern doubt — flagged Aug 12, 2026

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.”

Who Holds ACGCU

Last 1 quarters through Jun 30, 2026

Each kind of 13F filer's share of the common shares 13F filers report. Holder type comes from regulatory records, never the filer's name; style, turnover and horizon are measured from each filer's own 13F book. The quarter selector does not change this card.

Jun 30, 2026: 10 filers, like-for-like change —.

Holder type Share Filers Change
Registered adviser 30.7% 5 new
Exempt adviser 19.0% 1 new
Adviser 34.1% 1 new
Non-US 9.5% 1 new

How the mix is measured

Shares are 13F common shares restated to today's split basis; options and principal amounts are left out. The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none was. Actively managed books are those measured systematic-like, concentrated or diversified active.

Conviction and Crowding

10 13F filers, quarter ended Jun 30, 2026

Measured across every 13F filer's common-share book once the quarter's filing window closed. Crowding counts filers with high turnover or that advise private funds on Form ADV.

Estimated Holder Cost Basis

Quarter ended Jun 30, 2026, on that quarter's share basis

Estimated, never filed: each 13F buy is costed at its quarter's average traded price and each sale keeps the average cost, so this is what holders paid on average if they traded evenly through each quarter.
