Substantial doubt about the company's ability to continue as a going concern.
“The liquidity condition and mandatory liquidation raise substantial doubt about the Company's ability to continue as a going concern until the earlier of the consummation of the Business Combination or the date the Company is required to liquidate. There is no assurance that the Company's plans to raise additional capital (to the extent ultimately necessary) or to consummate a Business Combination will be successful or successful within the Combination Period. The condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.”View the 10-Q filed Aug 13, 2026

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
8 13F filers, quarter ended Jun 30, 2026Measured 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.
Managers in the top fifth by current three-year FundScore alpha were net buyers of $0 (0 buying, 0 selling).
Estimated Holder Cost Basis
Quarter ended Jun 30, 2026, on that quarter's share basisEstimated, 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.
Estimated cost covers 61.0% of the 13F shares; positions already held when a filer's 13F history starts, or bought in a quarter without a trusted average price, have no estimate.
