(NASDAQ: MCGAU) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nYorkville Acquisition Corp. is listed on NASDAQ under ticker MCGAU, with ISIN USG986591083. The LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US).

The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 23 filings on 17 filing days in the window 2025-11-08 to 2026-11-08. Of these, 12 are regulatory filings, 4 are results, 3 are corporate news, 2 are director changes and 2 are directors' dealings. The median gap between filing days is 6.0 days. The latest filing is dated 2026-08-13, a regulatory filing, 87 days before the record date 2026-11-08.

The segment move is not on the record (the exchanges' tier transfers are not EDGAR filings). The halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable: the chapter's orderability section carries no client categories, so the outcome cannot name its client category.
