National Grid PLC (NGG), an SEC filer in Natural Gas Transmission, closed at $79.35, -0.1%, on 2026-08-28, with a return on equity of 8.6%, a net margin of 15.8% and 3-year sales growth of -0.1%. Institutional ownership, earnings history and filed financials are on the tabs below.
% of shares outstanding not shown: this line files 20-F annual reports only — a foreign private issuer whose US listing trades as ADSs (depositary receipts), while its cover-page share count is in ORDINARY shares. The depositary ratio is not in our data. The count we hold for this line is 5,198,968,690 shares (as of 2026-03-31, source dei). Dividing one by the other is wrong by the whole ratio (a 5:1 ADR reads one fifth of the true percentage), so the percentage is withheld rather than served wrong. Holder share counts are shown as filed.
Crowding percentile lands with its cohort — the cohort is size-matched, so it needs a market cap for NGG in the served universe — that lands with the next screener build.
