(NASDAQ: BSAAU) — 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 BSAAU, with ISIN USG1069P1371. The LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US). The security type is Corporate and the sector is 8200 Services-Educational Services. The segment and the jurisdiction are not on the record. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 25 filings in the twelve months to 2026-11-08, on 19 filing days. The median gap between filing days is 12.0 days. The latest filing is dated 2026-11-05, 3 days before the record date, and is of type results. Its exchange peers, 4359 issuers, have a median cadence gap of 6.0 days, a median of 52 filings and a median latency of 5.0 days. Its sector peers, 44 issuers, have a median cadence gap of 8.5 days, a median of 38.0 filings and a median latency of 11.0 days. The issuer's filings by type are 13 regulatory filings, 5 results, 3 AGM or EGM, 2 directors' dealings, 1 ad hoc and 1 halt or suspension.\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 events. The domicile change is not on the record (EDGAR states no dated change of state of incorporation on a filing line). The segment move is not on the record (the exchanges' tier transfers are not EDGAR filings). The halt status is listed, not halted.\n\n## Orderability\n\nThe orderability 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.\n\n## Licensed\n\nLicensed research: none loaded.

The market's earliest sealed date is 2021-01-04. 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/BSAAU (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/BSAAU (the record)\n",
