 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# NATIONAL GRID PLC (NYSE: NGG) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is NATIONAL GRID PLC, listed on the NYSE under ticker NGG, with ISIN US6362744095 and LEI 8R95QZMKZLJX5Q2XR704. Its security type is recorded as non-operating entity type (other), its segment is not on the record, its sector is 4922 Natural Gas Transmission, and its jurisdiction is not on the record. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 45 filings across 35 filing days in the window 2025-11-08 to 2026-11-08, comprising 2 prospectus, 5 regulatory filing and 38 results filings. The median gap between filing days is 7.5 days. The latest filing is a results filing dated 2026-11-05, which is 3 days before the record date of 2026-11-08. The NYSE median cadence gap is 6.0 days across 3256 issuers, with a median of 64.0 filings and a median latency of 4.0 days. The sector median cadence gap is 6.0 days across 22 issuers, with a median of 53.0 filings and a median latency of 3.0 days.\n\n## Auditor\n\nThe auditor is not on the record, as the latest annual report cover carries no dei:AuditorName tag, and its location is not on the record. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds two listing lines, both dated 2026-06-12, and no 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 reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable, as 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 investor-relations pages read, and the count is 0.\n\n## Open research\n\nNo openly published research notes were found, 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 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://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://data.sec.gov/submissions/CIK0001004315.json (identity.name)\n- https://mcp.us-cm-kg.ai/events/NYSE/NGG (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NYSE/NGG (the record)\n",
