NGG Valuation Metrics & Historical Range

The valuation table above shows National Grid PLC's current and historical valuation multiples, including P/E ratio, P/S ratio, EV/EBITDA, FCF yield, and dividend yield. Each metric is compared to its own historical range to determine whether NGG is currently trading above or below its typical valuation levels.

  • P/S ratio: Price-to-sales is useful for companies with volatile or negative earnings. Lower P/S relative to history may indicate value.
  • EV/EBITDA: Enterprise value to EBITDA adjusts for debt and cash, providing a capital-structure-neutral valuation measure for National Grid PLC.
  • FCF yield: Free cash flow yield shows the cash return relative to market price. Higher yields may indicate undervaluation.
