Going-concern doubt — flagged May 15, 2026

Substantial doubt about the company's ability to continue as a going concern.

“management has determined that the Company’s projected liquidity condition raises substantial doubt about the Company’s ability to continue as a going concern. Management intends to address this liquidity need through Working Capital Loans from the Sponsor or its affiliates and by completing a Business Combination; however, there can be no assurance that these plans will be successfully implemented.”

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.
