YCY · AA Mission Acquisition Corp. II · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“As of June 30, 2026, the Company had $244,932 in cash and cash equivalents and a working capital of $135,351. The Company has incurred and expects to continue to incur significant costs as a publicly traded company, to evaluate business opportunities, and to close on a Business Combination. Such costs will be incurred prior to generating any operating revenues. These factors also raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that the financial statements are issued.”View the 10-Q filed Aug 7, 2026
Every disclosed holder of YCY 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.

Insiders are listed but not summed: the issuer has more than one class of common stock and Forms 3, 4 and 5 report one issuer-wide balance across them.
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.
