 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# MIDDLESEX WATER CO (NASDAQ: MSEX) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is MIDDLESEX WATER CO, listed on NASDAQ under ticker MSEX, with ISIN US5966801087. The LEI is not on the record: no GLEIF record with the exact legal name in jurisdiction US-NJ. The security type is Corporate. The segment is not on the record. The sector is 4941 Water Supply, and the jurisdiction is United States, New Jersey. The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 48 filings in the twelve months to 2026-11-08, across 25 filing days. The median gap between filing days is 5.0 days. The latest filing is dated 2026-10-29 and is of type results, 10 days before the record date. The exchange median gap is 6.0 days across 4,359 issuers, and the exchange median latency is 5.0 days. The sector median gap is 6.0 days across 14 issuers, and the sector median latency is 5.0 days. The issuer's 48 filings are below the exchange median of 52 and below the sector median of 69.5.\n\n## Auditor\n\nThe auditor of record is PricewaterhouseCoopers LLP, located in New York, New York. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change events. The domicile change is not on the record, since EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, since the exchanges' tier transfers are not EDGAR filings. The halt flag reads 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 pages read. 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's sealed years are 2021, 2022, 2023, 2024, 2025 and 2026. The market's vintage is sealed, with the earliest sealed date 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/CIK0000066004.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/MSEX (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/66004/000162828026009777/msex-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/NASDAQ/MSEX (the record)\n",
