 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# HUDSON TECHNOLOGIES INC /NY (NASDAQ: HDSN) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is HUDSON TECHNOLOGIES INC /NY, listed on NASDAQ under ticker HDSN. Its ISIN is US4441441098 and its LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US-NY). Its security type is Corporate, its segment is not on the record, its sector is 5080 Wholesale-Machinery, Equipment & Supplies, and its jurisdiction is United States, New York. Its status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 73 filings across 52 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 6 days, and the median latency from the latest filing to the record date is 3 days. The exchange median is 52 filings, a cadence gap of 6.0 days and a latency of 5.0 days. The sector median is 63.5 filings, a cadence gap of 6.0 days and a latency of 3.0 days. The latest filing is dated 2026-11-05 and is of type results.\n\n## Auditor\n\nThe auditor of record is BDO USA, P.C., located in Stamford, Connecticut. 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 issuer is listed and 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 own 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 issuer's years sealed 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\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/CIK0000925528.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/HDSN (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/925528/000110465926028445/hdsn-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/HDSN (the record)\n",
