NATIONAL GRID PLC Annual Report - How They Did This Year

I’ve put together this guide to help you understand National Grid’s latest annual report for the year ending March 31, 2026. Instead of wading through hundreds of pages of dense financial reports, I’ve broken down the key points so you can see how the company is performing and what it means for your investment.

1. What does this company do?

National Grid is the backbone of the energy system. They own and operate high-voltage electricity networks in England and Wales, plus electricity distribution networks in the UK. In the US, they provide electricity and gas to millions of customers across New York and Massachusetts. Think of them as a toll-road operator for energy. They don't create the power, but they earn steady, regulated fees for ensuring it reaches homes and businesses safely.

2. Financial performance

For the year ending March 31, 2026, National Grid reported an underlying operating profit of £4,858 million. The company manages a large balance sheet, with total debt minus cash standing at £44,357 million as of March 31, 2026.

The company uses financial tools to protect itself from currency swings—specifically the US Dollar—and interest rate changes.

• Cash Position: As of March 31, 2026, the company held £2,456 million in cash. They also have access to £6,380 million in unused credit lines to fund their ongoing construction projects.
• Dividends: The company declared a total dividend of 58.52 pence per share for the 2025/26 fiscal year.

3. Major wins and challenges

The shift toward green energy is the company’s main growth driver. They are investing heavily to connect new renewable energy sources to the grid, which is vital for meeting government climate targets.

The challenge is the massive cost of these upgrades. To fund them, the company borrows money in long-term debt markets. For example, they recently secured an £864.9 million 10-year loan for their US operations. Their strategy is to borrow long-term to build assets that provide reliable income for decades.

4. Financial health

National Grid is a classic utility. They carry high debt because building and maintaining power lines and gas pipes is expensive. They manage this by issuing various bonds, including notes maturing in 2028, 2033, and 2034. As an investor, view them as a slow and steady play. They prioritize consistent, regulated returns over fast growth, supported by a growing base of infrastructure assets.

5. Key risks that could hurt the stock price

• Regulatory Changes: Governments and regulators, such as Ofgem in the UK and state commissions in the US, strictly control how much profit the company can make. If they lower these allowed rates, National Grid’s profit drops.
• Interest Rates: Because they rely on debt to fund construction, high interest rates make it more expensive to manage their £44,357 million debt pile. This can shrink profit margins.
• Operational Risks: Managing physical lines and pipes carries the risk of accidents, cyber-attacks, or equipment failure. These are expensive to fix and can lead to government fines.
• Market Volatility: They face risks from commodity price swings and currency changes. While they use financial tools to hedge these, the cost of those protections can change.

6. Competitive positioning

National Grid operates as a regulated monopoly in its service areas. They don't face traditional market competition. Their primary "competitor" is the regulatory process—the ongoing negotiation to ensure they can charge enough to cover their construction costs and provide a fair return to shareholders.

7. Future outlook

The company is in a phase of heavy investment, focusing on decarbonization. They are positioning themselves as the main partner for the UK and US governments to reach "Net Zero" emissions by 2050. This involves shifting toward electricity-heavy infrastructure and away from traditional gas, requiring high levels of spending for the foreseeable future.

8. The Bottom Line for Investors

National Grid is a utility for the long-term investor seeking stability rather than quick gains. The company acts as the foundation for the green energy transition. When evaluating your position, watch their debt levels and any updates on regulatory rate reviews. These are the two main factors that dictate their ability to pay dividends and grow.
