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 FASB ASC 2014-15, "Disclosures of Uncertainties about an Entity'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 unaudited condensed consolidated financial statements are issued as it expects to continue to incur significant costs in pursuit of its acquisition plans. In addition, if the Company is unable to complete an initial business combination by November 12, 2026, then the Company will cease all operations except for the purpose of liquidating. The date for mandatory liquidation and subsequent dissolution and liquidity concerns 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 mandatory liquidation date. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after November 12, 2026.”View the 10-Q filed Aug 13, 2026
Every disclosed holder of ATIIU in one list: 13F institutions, Schedule 13D and 13G filers, insiders (Forms 3, 4 and 5) and registered funds, each from its own latest filing. Holders nest by CIK and SEC reporting links, never by name, and each is summed once.

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.
