National Grid (NGG) Q2 2027 Earnings Call Transcript

National Grid reported first-half underlying EPS growth of 22% to 36.5p and raised FY2027 EPS growth guidance to 15%–16%, alongside record first-half capital investment of £6.7 billion, up 32% at constant currency. Full-year investment guidance increased to £13.5 billion, supporting a five-year plan of at least £70 billion; the interim dividend rose 3.8% to 16.97p per share. Net debt increased £4.5 billion to £48.6 billion, while New England underlying operating profit fell 10% and management cited Middle East conflict as pressure on consumer energy bills.

Analysis

NGG’s upside is increasingly a regulated-returns and execution story, not simply a volume-growth story: faster asset deployment can lift the earnings base, but only if regulators permit timely recovery and delivery costs stay within allowed economics. The key distinction is that secured supply-chain arrangements reduce schedule risk; they do not by themselves eliminate unit-cost inflation, construction slippage, or financing dilution. Higher debt therefore makes realized returns and cash conversion more important than headline CapEx growth.

Near term, reported EPS quality is weaker than the growth rate implies: portfolio gains are non-recurring, while higher depreciation and New England cost pressure are evidence that investment can dilute segment profit before the revenue benefit catches up. Over 1–3 months, U.S. rate-case outcomes and Joulent’s final investment decision are more informative than the raised annual guidance. For Joulent, Microsoft’s long-term offtake reduces demand risk, but does not remove construction, counterparty-structure, or capital-recovery risk; the project remains an adjacency, not a reason to underwrite NGG as a data-center pure play. Micron’s expansion is a potential load driver for NGG, while the split between customer-paid connections and socialized reinforcement is a regulatory sensitivity—not a clean direct read-through to MU.

Contrarian view: investors may discount the one-off EPS uplift and overlook the duration of regulated asset growth, but management’s “secured” supply chain can also encourage extrapolation before cost and rate recovery are proven. No valuation data is supplied, so avoid chasing the guidance upgrade; monitor cost overruns, cash conversion, and allowed returns.

Key Decisions for Investors

• NGG: do not chase the results-day EPS upgrade. Consider scaling into a long only on weakness, contingent on valuation review; reassess if rate-case outcomes weaken allowed returns, the FY27 outlook is cut, or delivery costs materially erode the investment economics.
• Set a 1–3 month catalyst alert for U.S. rate-case filings/outcomes and Joulent’s final investment decision. For Joulent, verify funding protections, capital commitments, and project-level recovery before assigning meaningful incremental value to the pipeline.
• Treat the EPS beat as partly non-repeatable: track recurring regulated operating profit and operating cash flow against rising investment and debt, rather than extrapolating portfolio gains.
• Watch for evidence that large-load reinforcement costs are allocated to customers rather than broadly recovered from ratepayers; adverse regulatory treatment could slow demand-led investment returns and weaken the NGG thesis.
