JACS · Jackson Acquisition Co II · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“In connection with the Company's assessment of going concern considerations in accordance with ASC 205-40, "Presentation of Financial Statements – Going Concern," as of June 30, 2026, the Company has determined that mandatory liquidation and subsequent dissolution, should the Company be unable to complete a Business Combination, raises substantial doubt about the Company's ability to continue as a going concern. The Company has until December 11, 2026 to consummate a Business Combination. Additionally, the expectation of significant future costs raises substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued. Management plans to address this uncertainty through debt or equity financing. There is no assurance that our plans to raise capital or to consummate a business combination will be successful within the Completion Window. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution.”View the 10-Q filed Aug 11, 2026

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.
