(NASDAQ: ALGM) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is ALLEGRO MICROSYSTEMS, INC., listed on NASDAQ under ticker ALGM, with ISIN US01749D1054 and LEI 54930004TGPV6DR3LE12. Its security type is Corporate and its sector is 3674 Semiconductors & Related Devices. 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 85 filings on 49 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 3.5 days, against a NASDAQ median of 6.0 days and a sector median of 4.0 days. The latest filing is dated 2026-11-05, three days before the record date, and is a regulatory_filing. The NASDAQ median latency is 5.0 days and the sector median latency is 4.0 days.\n\n## Auditor\n\nThe auditor is not on the record, because the latest annual report cover carries no dei:AuditorName tag. The auditor's location is not on the record. 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 is listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable, because the chapter's orderability section carries no client_categories and 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 pages read.\n\n## Open research\n\nNo openly published research notes were found.\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 record holds sealed years 2021, 2022, 2023, 2024, 2025 and 2026 for this issuer. 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://api.gleif.org/api/v1/lei-records/54930004TGPV6DR3LE12 (identity.lei)\n- https://data.sec.gov/submissions/CIK0000866291.json (identity.name)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/ALGM (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/ALGM (the record)\n",
