National Grid Transco PLC National Grid PLC (NEW) American Depositary Shares (NGG) : juste valeur

Thèse ACCE

National Grid operates the electricity transmission and distribution networks across England, Wales, and the northeastern United States, collecting regulated tariffs on power flows rather than generating or selling power itself. The business benefits from essential infrastructure status: demand is inelastic, competitors cannot replicate the physical networks, and regulators set allowed returns on invested capital, creating predictable cash flows. The company is investing heavily in grid modernization and electrification infrastructure to support the UK and US transition away from fossil fuels, with capex expected to remain elevated through the decade. Trading at a forward PE of 11.6x against a 32.6% operating margin, the stock offers the yield and stability of a utility without the commodity exposure of generation assets, though the 8.4% ROE reflects the capital intensity of the business and regulatory constraints on returns. The regulatory environment remains the key variable: changes to allowed return rates in either jurisdiction could materially shift cash generation and valuation.
