Bernstein resumes coverage on National Grid on regulated growth outlook

Bernstein resumed coverage of National Grid with an outperform rating and 1,310p target, identifying the stock as its top European regulated-network pick. The broker forecasts roughly 10% EPS and regulated asset base CAGR, a 4% FY2027 dividend yield, and about 14% five-year total shareholder return versus 11% for the sector. National Grid trades about 20% below recent highs and at an 18% discount to long-term valuation averages, though elevated UK/US bond yields, inflation, political intervention, U.S. affordability pressures and transmission-project execution risks remain key headwinds.

Analysis

NGG is effectively a long-duration regulated-infrastructure asset whose valuation remains more sensitive to real yields and allowed-return mechanics than to near-term electricity volumes. The key earnings debate is whether asset-base compounding converts into per-share growth after financing costs, equity issuance and execution slippage; a sustained 50 bp rise in UK/US long-end yields can offset a meaningful portion of the valuation benefit from a 10% RAB growth profile. The 1-3 month catalyst is any decline in gilt/Treasury yields or regulatory confirmation that inflation-indexed revenue frameworks preserve real returns; the 6-18 month catalyst is project commissioning translating approved capex into earning assets.

The less appreciated risk is political and affordability pressure: regulators can maintain nominal allowed ROEs while extending recovery periods, disallowing portions of capex, or imposing customer-bill mitigants, all of which reduce cash conversion without an obvious headline rate-cut. NGG's US rate-stabilization approach should be viewed as a warning that the return profile may become more back-end loaded. IBE has indirect downside through its Scottish Power partnership exposure if transmission delays create cost overruns or revise delivery incentives, but its diversified generation and networks base makes it a cleaner relative hedge against NGG-specific UK regulatory risk.

Consensus appears to treat the valuation discount as a straightforward mean-reversion opportunity. That is incomplete if the market is repricing UK networks from a bond-proxy multiple toward a politically constrained public-service multiple, particularly while long-duration discount rates remain elevated. The thesis is falsified positively by a rate settlement preserving real returns and capex recovery with no material delay; negatively by further project timetable revisions, a weaker-than-allowed US ROE trend, or a UK policy proposal that constrains shareholder distributions or asset returns.

Key Decisions for Investors

• Initiate a phased long NGG position over the next 1-3 months only on a pullback or after confirmation that UK regulatory determinations preserve inflation pass-through; target a 12-18 month rerating plus earnings-growth return, with risk controlled by exiting if regulatory language indicates capex disallowance or dividend-cover deterioration.
• Express the rates-sensitive component with long NGG / short XLU or short a broad regulated-utility basket, sized beta-neutral. NGG offers greater transmission-capex growth, while the short leg reduces exposure to a broad decline in long-end yields; reassess after US rate-case clarity or the next UK regulatory update.
• For a more conservative relative-value structure, pair long NGG against long IBE only if NGG's discount widens further despite stable allowed-return guidance. IBE is the appropriate partial hedge for shared UK transmission execution risk, but avoid a full NGG/IBE spread until the financial liability for delayed joint projects is independently quantified.
• Set a catalyst alert around UK gilt and US 10-year yield moves: a 25-50 bp rally in long yields without worsening regulatory rhetoric supports adding exposure; a renewed yield breakout above recent highs argues against averaging down because multiple compression can dominate regulated-asset growth in the near term.
