(NYSE: TGEN) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is TECOGEN INC., listed on the NYSE under ticker TGEN, with ISIN US87876P2011 and LEI 549300GD898YRLK9SS61. Its security type is Corporate. Its segment is not on the record. Its sector is 3585 Air-Cond & Warm Air Heatg Equip & Comm & Indl Refrig Equip, and its jurisdiction is United States, Delaware. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 46 filings across 25 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 5.5 days, against a median of 6.0 days for the NYSE and 5.0 days for the sector. The latest filing is dated 2026-10-14, a corporate news filing, 25 days before the record date. The median filing count is 64.0 for the NYSE and 63.5 for the sector, and the median latency is 4.0 days for the NYSE and 14.5 days for the sector.\n\n## Auditor\n\nThe auditor of record is WOLF & COMPANY, P.C., located in Boston, Massachusetts. 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 exchange tier transfers are not EDGAR filings. The halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable for any client category, because the chapter's orderability section carries no client categories. The rule version is acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, with the chapter as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the investor-relations pages read, and the count is 0.\n\n## Open research\n\nNo openly published research notes were found on the record, and the count is 0.\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 issuer's sealed years 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\n9 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/CIK0001537435.json (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.us-cm-kg.ai/events/NYSE/TGEN (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1537435/000153743526000013/tgen-20251231.htm (the auditor)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NYSE/TGEN (the record)\n",
