 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# ALPHA & OMEGA SEMICONDUCTOR Ltd (NASDAQ: AOSL) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is ALPHA & OMEGA SEMICONDUCTOR Ltd, listed on NASDAQ under ticker AOSL, with ISIN USG6331P1042 and LEI not on the record (no GLEIF record with the exact legal name in jurisdiction US). Its security type is Corporate and its sector is 3674 Semiconductors & Related Devices. Its segment and jurisdiction are not on the record. Its status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 82 filings on 50 filing days in the twelve months to 2026-11-08, from 2025-11-08. The median gap between filing days is 4 days, against a NASDAQ median of 6.0 days and a sector median of 4.0 days. The latest filing is a results filing dated 2026-11-06, 2 days before the record date, against a NASDAQ median latency of 5.0 days and a sector median of 4.0 days. The filings by type are 45 directors' dealings, 22 regulatory filings, 8 results, 3 AGM/EGM, 3 director changes and 1 takeover. The NASDAQ median is 52 filings and the sector median is 96.0 filings.\n\n## Auditor\n\nThe auditor of record is Deloitte & Touche LLP, located in San Jose, 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, since EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, since the exchanges' tier transfers are not EDGAR filings. The issuer is listed and not halted.\n\n## Orderability\n\nThe outcome is not determinable, because the chapter's orderability section carries no client categories and 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 pages read.\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 vintage is sealed. Sealed years that hold the issuer are 2021, 2022, 2023, 2024, 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/CIK0001387467.json (identity.name)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/AOSL (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1387467/000162828026059261/aosl-20260630.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/AOSL (the record)\n",
