(NASDAQ: BSAA) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is BEST SPAC I Acquisition Corp., listed on NASDAQ under ticker BSAA. Its ISIN is USG1069P1033 and its LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US). Its security type is Corporate, its sector is 8200 Services-Educational Services, and its segment and jurisdiction are not on the record. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 25 filings across 19 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 12.0 days, against a NASDAQ median of 6.0 days across 4,359 issuers and a sector median of 8.5 days across 44 issuers. The latest filing is a results filing dated 2026-11-05, three days before the record date of 2026-11-08, against a NASDAQ median latency of 5.0 days and a sector median latency of 11.0 days. The window holds 13 regulatory filings, 5 results, 3 AGM or EGM filings, 2 directors' dealings, 1 ad hoc, and 1 halt or suspension filing.\n\n## Auditor\n\nThe auditor of record is WWC, P.C., located in San Mateo, California. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines. The domicile change is not on the record, because EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, because 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. The rule version is acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, and the chapter is as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations page.\n\n## Open research\n\nNo openly published research notes were found on the record.\n\n## Licensed\n\nLicensed research: none loaded. A licensed row is served only to an agent whose firm holds that licence (licensor, entitlement). No licensed row is loaded.\n\n## As-of depth\n\nThe sealed years that hold the issuer are 2025 and 2026. The market's earliest sealed date is 2021-01-04, and the live record began on 2026-09-12.\n\n## Sources\n\n8 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://www.sec.gov/files/company_tickers_exchange.json (identity.exchange)\n- https://www.sec.gov/data-research/sec-markets-data/fails-deliver-data (identity.isin)\n- https://data.sec.gov/submissions/CIK0002051587.json (identity.name)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/BSAA (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/2051587/000121390026013671/ea0274054-10k_bestspac1.htm (the auditor)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/BSAA (the record)\n",
