ILLUU · Illumination Acquisition Corp. I · Shareholders & Ownership
Substantial doubt about the company'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 accompanying unaudited condensed financial statements are issued as it expects to continue to incur significant costs in pursuit of its acquisition plans. In addition, Management has determined that if the Company is unable to complete an initial Business Combination within the Completion Window, then the Company will cease all operations except for the purpose of liquidating. These conditions raise substantial doubt about the Company's ability to continue as a going concern.”View the 10-Q filed Oct 14, 2026
Every disclosed holder of ILLUU 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.

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.
