Going-concern doubt
— flagged May 6, 2026
Substantial doubt about the company's ability to continue as a going concern.
“The Company's liquidity condition and mandatory liquidation within one year of the issuance of these unaudited condensed financial statements raise substantial doubt about the Company's ability to continue as a going concern. Management plans to address this uncertainty through an initial business combination. However, there can be no assurance that the Company will be able to consummate any initial business combination by the end of the Completion Window.”View the 10-Q filed May 6, 2026

Institutional ownership from SEC Form 13F filings. Investment managers with more than $100 million in U.S. equities must disclose their positions every quarter, within 45 days of quarter-end, so the holdings shown can lag the market by up to a quarter.
The Jun 30, 2026 filing window is
still open — showing the latest known positions. Funds that have not filed yet
carry their prior-quarter positions; a fund that filed without this stock counts
as sold out.
