 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# Terrestrial Energy Inc. /DE/ (NASDAQ: IMSR) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nTerrestrial Energy Inc. /DE/ is listed on NASDAQ under ticker IMSR, with ISIN US8814541020; its LEI is not on the record, as no GLEIF record carries the exact legal name in jurisdiction US-DE. The security type is Corporate, the segment is not on the record, the sector is 3443 Fabricated Plate Work (Boiler Shops), and the jurisdiction is United States, Delaware. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 73 filings in the window 2025-11-08 to 2026-11-08, across 40 filing days. Of the filings, 26 are directors_dealings, 15 are regulatory_filing, 11 are prospectus, 8 are results, 6 are director_change, 3 are corporate_news, 3 are agm_egm, and 1 is ad_hoc. The median gap between filing days is 5 days. The latest filing is dated 2026-11-03 and is a regulatory_filing, 5 days before the record date of 2026-11-08, where the median latency is 5.0 days for NASDAQ and 3.0 days for the sector. The NASDAQ median is 52 filings across 4,359 issuers with a median cadence gap of 6.0 days, and the sector median is 61.5 filings across 10 issuers with a median cadence gap of 4.0 days. The issuer's 73 filings are above the NASDAQ median of 52 and above the sector median of 61.5.\n\n## Auditor\n\nThe auditor of record is UHY LLP, located in Melville, New York. The record shows one auditor change, dated 2025-11-24.\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 is clear: listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable under rule version acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, as of chapter date 2026-11-04. The chapter's orderability section carries no client_categories, so the outcome cannot name its client category.\n\n## Coverage\n\nNo research houses were found on the issuer's own investor-relations page; the count is 0.\n\n## Open research\n\nNo openly published research notes were found on the record; 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 is sealed for the years 2024, 2025 and 2026. The market's vintage is sealed, with an earliest sealed date of 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/CIK0002019804.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/IMSR (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/2019804/000110465926036846/tmb-20251231x10k.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/IMSR (the record)\n",
