 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# CECO ENVIRONMENTAL CORP (TXSE: CECO) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is CECO ENVIRONMENTAL CORP, listed on TXSE under ticker CECO, with ISIN US1251411013 and LEI 5493002CZCTL4HGLIY91. Its security type is Corporate. Its segment is not on the record. Its sector is 3564 Industrial & Commercial Fans & Blowers & Air Purifing Equip, and its jurisdiction is United States — Delaware. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 81 filings in the twelve months to 2026-11-08, across 48 filing days. The median gap between filing days is 4 days. The latest filing is dated 2026-11-05, a regulatory filing, 3 days before the record date. On TXSE the median cadence gap is 7.0 days, the median filings count is 67.5 and the median latency is 3.0 days across 12 issuers. In the sector the median cadence gap is 6 days, the median filings count is 66 and the median latency is 3 days across 5 issuers. The issuer's count of 81 filings is above both the exchange median of 67.5 and the sector median of 66. Its median cadence gap of 4 days is below the exchange median of 7.0 days and the sector median of 6 days.\n\n## Auditor\n\nThe auditor of record is Deloitte & Touche LLP, located in Dallas, Texas. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds a delisting dated 2026-10-16 and two listings dated 2026-10-16. It holds no name change. Domicile change is not on the record, as EDGAR states no dated change of state of incorporation on a filing line. Segment move is not on the record, as the exchanges' tier transfers are not EDGAR filings. The halt flag shows listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable. The chapter's orderability section carries no client categories, 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 page.\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. 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/CIK0000003197.json (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.us-cm-kg.ai/events/TXSE/CECO (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/3197/000119312526085815/ceco-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/TXSE/CECO (the record)\n",
