National Grid posts higher FY26 earnings, targets £70 billion five-year investment

National Grid reported underlying operating profit of £5.68 billion, up 6%, with underlying EPS rising 8% to 78.0 pence for fiscal 2026. Capital investment hit a record £11.6 billion and net debt increased to £44.2 billion, but management guided to 13-15% EPS growth in fiscal 2027 and at least £70 billion of network investment through 2030/31. The board recommended a full-year dividend of 48.49 pence per share, reinforcing its income profile.

Analysis

National Grid is becoming less of a defensive utility and more of a regulated capital compounding story. The important second-order effect is that the market should start underwriting a higher-quality earnings stream once RIIO-T3 feed-through offsets the near-term balance-sheet strain; in utilities, the setup where capex accelerates before returns reset is often the point where multiples expand, not contract. That makes NGG attractive versus slower-growth European regulated peers, especially if investors increasingly value visible 8-10% asset growth over stagnant yield plays.

The main risk is duration mismatch: the equity benefits from regulated revenue uplift over the next 12-36 months, but the debt burden and funding needs are immediate. If rates stay higher for longer, incremental equity risk premium can offset the headline EPS growth, and any delay in project execution would hit sentiment hard because the story depends on converting spend into allowed returns on schedule. A secondary watch item is political/regulatory friction in the U.K. around bill affordability; if public pressure forces a softer allowed-return posture, the market will quickly de-rate the whole investment program.

The contrarian angle is that investors may be too focused on the dividend and not enough on the embedded call option from a larger transmission build-out. The dividend is supportive, but the real upside is that a multi-year network supercycle can re-rate NGG from a bond proxy to a regulated infrastructure compounder if execution remains clean. That creates asymmetric upside over the next 6-18 months, while the near-term downside is mostly a financing/rates story rather than an operating one.

In portfolio terms, this is more compelling as a relative-value long than a standalone yield buy: the catalyst path is visible, but the market may need one or two clean regulatory updates to fully price it. If management demonstrates capex discipline and the first RIIO-T3 benefits show up as expected, this can outperform on both earnings revisions and multiple expansion.

Key Decisions for Investors

• Long NGG on a 3-6 month horizon: prefer entries on any post-guidance weakness; risk/reward is favorable if the market starts capitalizing RIIO-T3 earnings uplift before debt concerns dominate.
• Pair trade: long NGG / short a slower-growth European utility peer with weaker capex visibility over the next 6-12 months; the spread should work if investors rotate toward regulated growth over pure yield.
• Buy NGG call spreads 6-12 months out to express upside from re-rating without taking full duration risk; best if rates stabilize and project execution remains on track.
• If NGG rallies sharply into the first post-guidance re-rating, trim 25-35% and keep the remainder as a long-duration compounding hold; the main risk is funding-cost pressure reasserting itself.
• For lower-risk income exposure, wait for evidence that the dividend is being funded comfortably after capex acceleration before adding size; otherwise the yield thesis may be a value trap if rates rise again.
