- Rating Downgrade: UBS has downgraded National Grid from Neutral to Sell with a price target of 1,160p, indicating that the current share price of 1,368p reflects asset growth and returns that are unlikely to materialize.
- Asset Premium Risk: The stock trades at a 57% premium to its regulated asset base, a level at the top of its 30-year historical range, with UBS noting that similar premiums have historically led to an average stock decline of 37% over 5-19 months.
- Strong Operating Performance: While National Grid's recent operating performance has been robust, with a group return on equity of approximately 10.6% across its U.K. and U.S. operations, analysts warn that consumer affordability pressures and supply chain challenges pose significant downside risks to capital expenditure delivery.
- Overestimated Market Expectations: UBS emphasizes that the stock price already fully prices in the benefits of the RIIO-T3 price control set for March 2026, with future capital expenditure delivery facing challenges such as planning constraints, potentially impacting the company's long-term growth prospects.

GridCARE and National Grid Collaborate on AI-Driven Grid Optimization
- Collaboration Goals: The partnership between GridCARE and National Grid aims to significantly reduce the connection time for large-load customers from the traditional 3-7 years to just 6-12 months through AI-driven grid optimization, enhancing grid reliability and economic benefits for customers.
- Technological Innovation: GridCARE's EnergizeTM platform employs generative AI models to evaluate quadrillions of grid operating scenarios, accurately identifying approximately one-third of the grid's underutilized capacity, thereby providing additional power support to customers and driving economic growth.
- Economic Impact: According to JLL's 2026 Global Data Center Outlook, hyperscale development typically requires around $10 million per megawatt in infrastructure investment, which is expected to create thousands of jobs and significant new tax revenues, indicating the potentially transformative economic impact of new AI capabilities.
- Cost Efficiency: By improving asset utilization, GridCARE's model not only accelerates the development of large loads but also maintains rate stability while reducing long-term rate pressure, ensuring that infrastructure costs remain justifiable and manageable.

Jefferies Downgrades National Grid to Hold Amid Thin Regulatory Outlook
- Rating Downgrade: Jefferies downgraded National Grid from Buy to Hold, resulting in a 2.7% drop in stock price during Wednesday's trading, reflecting a cautious market sentiment despite the stock being a core holding for many investors.
- Thin Regulatory Outlook: Analyst Ahmed Farman noted that while there are several regulatory updates expected in 2025, the lineup for the remainder of this year appears thin, negatively impacting sentiment as the stock trades at a premium valuation within the sector.
- Valuation Analysis: National Grid's FY27 regulated asset base premium stands at approximately 55%, significantly higher than the sector average of 30%, indicating that its valuation is at the high end among grid utilities, making further re-rating increasingly challenging.
- Future Outlook: Although the recent outlook upgrade provides five-year visibility to 2031, the lack of major regulatory updates, particularly the upcoming publication of the initial business plan for ED3 and a rate case filing for KEDNY/LI in the summer, diminishes investor confidence in future performance.
