London, June 15, 2026, 11:41 BST.
- National Grid traded around 1,196.5p, down 1.08%, underperforming a slightly higher FTSE 100.
- Investors are balancing regulated growth and dividend income against heavy capital spending, debt and execution risk.
- The next dates to watch are the June 18 scrip election deadline, the July 14 AGM, the July 23 final dividend payment, and the November 5 half-year results.
National Grid plc shares weakened on Monday, with the London-listed stock quoted at a 1,196.0p sell price and 1,196.5p buy price, down 13.0p, or 1.08%, while the FTSE 100 was slightly higher at the same delayed market snapshot. The move matters because National Grid is usually treated as a defensive utility: when it falls on a firmer market day, investors are often looking beyond the broad index and focusing on stock-specific issues such as valuation, dividend timing, debt and future returns on investment. Hargreaves Lansdown listed the stock on a 15.5 times price-to-earnings ratio and a 4.05% dividend yield; P/E is the share price divided by annual earnings per share, while dividend yield shows annual dividends as a percentage of the share price.
The latest pressure sits against a large investment story. National Grid’s May results showed £11.6 billion of capital investment in 2025/26, underlying earnings per share of 78.0p, up 8% at constant currency, and a proposed total dividend of 48.49p, up 3.8%. Chief Executive Zoë Yujnovich said the group was embarking on “the largest investment programme in our history,” with at least £70 billion planned over five years across the UK and the US Northeast. Underlying EPS means profit per share after stripping out certain items management says are not part of normal operating performance. Investegate
That is the bull case. National Grid has regulated assets, visible demand from electrification, and a new UK electricity transmission price-control period now in force. Ofgem’s RIIO-3 framework runs from April 1, 2026 to March 31, 2031, and National Grid said the RIIO-T3 determination for its electricity transmission business included a 6.12% real allowed cost of equity at 60% gearing. Allowed cost of equity is the regulator’s permitted return for shareholders on regulated investment, so it is central to how profitable grid expansion can be. National Grid has guided to 13%–15% underlying EPS growth in 2026/27, helped by higher allowed revenue as RIIO-T3 begins.
The bear case is not complicated either. Big grid spending must be financed, delivered on time and approved through regulators without damaging customer bills. Reuters reported after the May results that National Grid’s adjusted operating profit of £5.68 billion missed a company-compiled consensus of £5.75 billion, with US storm-repair costs weighing on the year; the company also reported £636 million of timing under-recoveries, meaning revenue it was allowed to collect but had not yet collected from customers during the period. Analyst opinion is mixed: MarketScreener showed Bank of America keeping a Buy view on Monday while lowering its price objective, Deutsche Bank cutting the stock to Hold on June 8, and UBS reiterating Sell on June 1.
For now, the shares look fairly valued to mildly attractive for income-focused investors, rather than obviously cheap. The dividend yield is useful, and analyst consensus still points to upside, with MarketScreener showing an average target of £13.69 versus a last close of £12.09. But the stock also carries clear risks: high investment needs, sensitivity to bond yields, regulatory decisions, US storm costs and the possibility that delivery problems eat into returns. Stocks usually rise when investors expect higher future cash flows, dividends or valuation multiples; they fall when those expectations are cut or when risk rises. For National Grid, the next real test is whether management can show at the July 14 AGM and then the November 5 half-year results that the £70 billion plan is turning regulatory visibility into earnings growth without putting too much strain on the balance sheet.
