Jefferies downgrades National Grid stock rating on valuation By Investing.com

Jefferies downgraded National Grid to Hold from Buy with a GBP14.10 price target (implying ~6% total shareholder return), citing premium valuation and limited regulatory catalysts; the stock has risen ~31% over six months and trades at a P/E of 23.37 and PEG of 0.71. InvestingPro flags the shares as overvalued vs Fair Value and Jefferies notes higher real rates as a headwind despite National Grid's five-year outlook to 2031. Separately, Goldman Sachs projects European datacenter capacity rising from ~15 GW today to 40 GW by 2031, which could add ~1.5% p.a. to European power demand from 2027–2031, creating sector-level tailwinds for utilities.

Analysis

NGG’s re-rating risk is best viewed through two levers: real yields and forward regulatory clarity. A sustained 100bp rise in real rates typically pressures regulated-asset multiples by ~1–2 turns; that alone can erase a meaningful portion of NGG’s recent outperformance within 6–12 months absent offsetting regulatory or cash-flow upgrades.

Goldman’s datacenter demand forecast creates a lumpy, location-specific capex cycle for European networks rather than a uniform demand tailwind; winners will be the transmission/connection owners in hyperscaler clusters and vendors of high-capacity transformers and switchgear. Expect project-level PPAs and private-wire builds to blunt some volumetric upside for incumbent utilities, shifting returns from commodity sales to connection and capacity fees between 2027–2031.

Second-order beneficiaries include industrial equipment suppliers and regional TSOs who can contract multi-year connection tariffs; losers are midstream or distribution players exposed to high upfront reinforcement capex with slow regulatory pass-through. Over the next 12–24 months the biggest catalysts are upcoming regulatory determinations and capex approval timelines—if regulators accelerate cost recovery mechanics the valuation gap compresses quickly, but a guarded regulatory stance prolongs multiple tail risk.

Consensus underweights the timing mismatch: datacenter-driven load is real but concentrated and back-end loaded, so near-term investor pain from rates and limited catalysts could persist even as structural demand for grid capacity increases materially by 2030.

Key Decisions for Investors

• Short NGG vs long SSE (12–18 months): pair trade to isolate valuation/rates risk. Target: NGG down ~15–25% relative to SSE if multiple compresses or cash-flow visibility disappoints. Hedge size to limit beta exposure; stop-loss at 10% adverse move in pair spread.
• Buy 12–18 month NGG puts (OTM) and sell nearer-term calls to finance (calendar collar): tail-protects portfolio from a >20% downside from a rates/regulatory shock while collecting premium. Max loss = premium paid plus assignment risk on short calls; reward is asymmetric protection into regulatory windows.
• Long GS (6–12 months) to capture financing/merchant-advisory upside from datacenter buildouts: GS should benefit from transaction volume and advisory fees as hyperscalers lock multi-year deals. Risk: macro slowdown reducing capex; size position to 1–2% NAV with review if datacenter orderbook cadence slows.
• Buy selective exposure to European grid-equipment suppliers (eg. ABB/Siemens exposure via ETF or suppliers) for 2027–2031 horizon: expect multi-year structural capex as datacenters force reinforcements. Time entries on drawdowns tied to rate spikes; expected IRR >10% if GS demand trajectory materializes.
