WLCO · Wilco 63 Corp · 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 FASB ASC 205-40, “Financial Statement Presentation — Going Concern,” the Company’s management has evaluated the Company’s liquidity and financial condition, and determined that the Company lacks the liquidity to sustain operations for a reasonable period of time, which is considered to be one year from the date of the issuance of the financial statements. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management plans to address this uncertainty by completing a Business Combination prior to the mandatory liquidation date. Management is actively evaluating potential target businesses and pursuing activities necessary to consummate a Business Combination within the Combination Period. However, there can be no assurance that the Company’s plans to complete the Business Combination will be successful. The unaudited condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.”View the 10-Q filed Aug 13, 2026

Every disclosed holder of WLCO 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.
Who Owns WLCO
13F quarter Sep 30, 2026, combined view: filers that have not filed yet carry their Jun 30, 2026 positions| Holder group | Shares | % Out |

Shares outstanding: 28,750,000, the issuer's latest cover-page count restated onto today's split basis.
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.
