Its security type is Corporate and its segment is not on the record. Its sector is 3842 Orthopedic, Prosthetic & Surgical Appliances & Supplies and its jurisdiction is United States, Delaware. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 49 filings in the window 2025-11-08 to 2026-11-08, across 29 filing days. The median gap between filing days is 6.5 days, against 6.0 days for NASDAQ and 5 days for the sector. The latest filing is dated 2026-11-05, 3 days before the record date, and is of type takeover. The median filings count is 52 for NASDAQ and 76 for the sector, and the median latency is 5.0 days for NASDAQ and 3 days for the sector.\n\n## Auditor\n\nThe auditor of record is Deloitte & Touche LLP, located in Los Angeles, California, USA. 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, as EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, as the exchanges' tier transfers are not EDGAR filings. The halt flag reads 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\nThe issuer's own investor-relations page names 3 research houses: Needham & Company, B. Riley Securities and Anderson.\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 record holds sealed years 2021, 2022, 2023, 2024, 2025 and 2026 for this issuer. The market's earliest sealed date is 2021-01-04, and the live record began on 2026-09-12.\n\n## Sources\n\n10 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://mapping.gleif.org/api/v2/isin-lei/latest (identity.isin)\n- https://data.sec.gov/submissions/CIK0001294133.json (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/INGN (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1294133/000119312526082630/ingn-20251231.htm (the auditor)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://investor.inogen.com/stock-data/analyst-coverage (coverage)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/INGN (the record)\n",
