NGG is not among the 142 companies we ingest every day, so it is not in the fundamentals screener or the size and group lists built from it. This page reads its SEC filings when the page is built. Ask us to add it: we keep a count per ticker and nothing about you.
NATIONAL GRID PLC (NGG) is a natural gas transmission company. Fundamentals from SEC filings; prices are end-of-day.
Every filed figure on this page is free to read, dated and sourced; no column is held back for a paid plan. Each section with figures says what date they are true as of and where they come from.
What’s behind NGG’s latest move — the size, how unusual the volume is, and the catalyst on the tape, explained and cited to the source.

This company reports under IFRS, so its figures come from the ifrs-full taxonomy rather than US GAAP. Year to 2025-03-31, from the 20-F filed 2025-05-29, in GBP as filed and never converted. Annual figures only: half-years on 6-K are not joined into a trailing year.

As filed. We do not recategorize line items. Each chart plots one XBRL concept exactly as NGG tagged it, period by period; a period the company did not tag on its own is left out, not estimated. A figure that disagrees with the filing is a bug in our extraction, not a policy, and we fix it: report a mismatch.
A plain-English read on NGG plus an auto-SWOT, built from NGG's SEC filings and market data, every point cited, nothing invented. Educational, not investment advice.
Four AI analysts, a bull, a bear, a risk manager, and a PM, debate NGG using only the SEC-filing and market facts below. Every point cites its evidence; nothing is invented. This is educational research, not investment advice.
Ask about NGG’s revenue, earnings, valuation, filings, insiders or Congress trades. Answers come only from the numbered evidence the research brief uses, each citing the items it rests on. A question about one figure is answered by code, free. One that puts figures together is 1 generation (Pro). A question about whether to buy, sell or hold, how much, or where the price goes gets a refusal.
Educational only — not financial advice. Data from SEC EDGAR public filings; no live market data is shown. Figures reflect the company's own reported XBRL facts and may lag.
Closes only, split-adjusted. An average needs that many sessions on file to print. These are measurements, not support, resistance or targets. Chart with studies
Daily closes from 2024-07-01 through 2026-11-06, 592 sessions, split-adjusted. No direction, pattern, entry, target or overbought label: these are measurements. Filings dated on the move days are in NGG’s filings; the chart with studies draws every figure.
Written by code from 592 end-of-day bars through 2026-11-06. Written by code from the data on file, not by a model. Information, not investment advice: it describes the security and recommends nothing to anyone.
Projected from NGG's own SEC 8-K filing history — the year-over-year reporting pattern (about 47% land the exact day, about 91% within a week, measured across 4,713 past reports). No analyst estimates and nothing invented, and every confirmed date links to the source it came from, so you can check it yourself. It upgrades the momentNGG files or announces.
Earnings dates are the company's 8-K Item 2.02 filings (SEC). Reactions from Databento EOD.
Nothing on file for NGG from Nov 9, 2026 to Nov 22, 2026 in these sources: earnings date and filing deadline.
| Event | Result |
|---|---|
| Earnings date | nothing in the window. No date in the window: no regular report cadence in the filings. |
| Filing deadline | nothing in the window. Nothing in the window: the 20-F for the fiscal year ending Mar 31, 2027, due four months after it, falls due Aug 2, 2027, after it. Newest periodic report on file: the 20-F for the period ending Mar 31, 2026, filed Jun 3, 2026. filing list on EDGAR |
| Ex-dividend date | not covered. Not checked. This attestation does not cover ex-dividend dates. |
This records what these sources returned when they were read. It is not a forecast: a company can announce an event at any time, and ex-dividend dates are not covered. Window 2026-11-09 to 2026-11-22, Eastern dates. Deadlines follow SEC Rules 13a-1 and 13a-13 and Form 20-F, moved past weekends and federal holidays by Rule 0-3.
2 of the 2 checks that ran found nothing new for NGG. 2 could not run.
Each event check looks back 30 days from the date its own source was stored, read or generated, never from the date this page was built. A check that finds nothing is a measurement of that window, not a forecast, and a check that cannot be dated does not make the claim at all.
No fair value band on this page build. No annual filing figures reached the estimators, either because the SEC read did not finish or because NGG has not filed annual figures yet. That is a statement about the read, not about NGG’s value. The page rebuilds daily.

One filed metric per row, each a ratio of two figures from the same annual report; no composite and no grade. Percentile is the share of the group’s other companies with a lower figure. A group prints from 6 companies with the figure. The group is drawn from our stored table (the S&P 500 issuers and the companies we cover, each with its newest annual report read), not from every filer in the class. Industry pages show the same medians by group.
