National Grid stock climbs, £70bn grid plan exceeds market cap

June 29, 2026

LONDON, June 29, 2026, 15:02 BST

  • National Grid rose 0.76% to 1,255p while the FTSE 100 lagged.
  • The £70 billion-plus five-year investment plan is around 1.12x the firm’s current market cap.
  • Analysts’ median target sits at 1,388.5p, suggesting the shares could rise roughly 11% from where they closed Monday.
  • Dividend still in focus. The FY2026 payout at 48.49p works out to a yield of about 3.9%.

National Grid plc (LON:NG) added ground Monday, outpacing the broader London market. Investors continued to pile in, backing a regulated asset-growth pitch with a footprint that now outstrips the company’s equity value.

The stock was last seen at 1,255p, up 0.76%, at 15:02:06 BST. It traded between 1,239.5p and 1,257p so far today. The FTSE 100 slipped 0.06% on the same feed. Reuters said UK shares lost ground earlier after Middle East tensions weighed on sentiment.

Scale is the point investors may miss. National Grid had a market cap of around £62.5 billion on Monday. Its five-year capital spend is at least £70 billion, so planned investment stands at about 112% of the company’s current market value. That’s a hefty figure for any regulated utility.

National Grid said in May it plans to invest at least £70 billion over five years ending March 2031. CEO Zoë Yujnovich called it the “largest investment programme in our history” and said the move aims to create “long-term value for shareholders.” Investegate

Bullish on growth, but not at a bargain: management is spending big to grow the regulated asset base and drive allowed returns. FY2026 underlying EPS came in at 78.0p, up 8% at constant currency. Capital investment was £11.6 billion, a jump of 18%. Regulatory gearing stayed at 61%.

This is making National Grid act less like a standard bond proxy and more like an execution story. RIIO-T3’s higher allowed revenue backs up the company’s FY2027 EPS growth target of 13%-15%, but it also means investors are on the hook for delivery risk, debt costs, and bill pressure.

The dividend keeps a floor under the stock for a lot of income funds. The board has proposed a final payout of 32.14p, set for July 23 if it gets the green light. That brings the total dividend to 48.49p for the year, up 3.8%. With Monday’s close, the yield sits around 3.9%, about in line with market averages.

The analyst split isn’t fully bullish. Latest Investors Chronicle data via LSEG puts 14 analysts on a median 12-month target at 1,388.5p as of June 25, broken out to three “buy”, seven “outperform”, six “hold” and two “sell” calls. Investors Chronicle

  • Sage Group Shares Rise on Buyback and AI Pricing Optimism
    June 29, 2026, 10:20 AM EDT. Sage Group plc shares edged up about 1% to 825p on June 29, despite a weaker UK market, as investors focus on the company's substantial buybacks and interim dividend. The accounting software firm has repurchased £600 million in shares this year, roughly 8% of its market value, alongside an 8.05p dividend payable in early July. Sage's half-year results showed robust growth with annualised recurring revenue up 11% to £2.73 billion and operating profit rising 15% to £326 million. CEO Steve Hare highlighted strong cash flows and margin improvements. Investors remain cautious, awaiting clear evidence that Sage's AI tools can enhance earnings and cloud-native revenue growth amid ongoing valuation pressures.
