Goldman Sachs Maintains Neutral Rating on United Utilities, Raises Target Price to 1,523p

Overview

Goldman Sachs published a commentary on United Utilities Group's strategic update. The company raised its capital investment, return, and asset growth guidance for the AMP8 regulatory period and supported the investment plan with an £800m equity financing. Goldman Sachs believes the new investment plan will enhance the company's growth and return expectations, raising the target price to 1,523p, but maintains a neutral rating given limited valuation upside and sector risks.

Core views

Strategic Upgrade Focused on Growth and Returns: United Utilities is increasing capital investment from £9bn to £11.5bn during the AMP8 regulatory period, raising the Regulatory Capital Value (RCV) CAGR guidance from 7% to 10%, with a target asset base of £25bn by 2030. The regulated return target is raised to 10%-11%, and outperformance guidance is increased from 100bps to 200bps, primarily driven by financing performance exceeding the Ofwat debt index model and short-term inflation upside. Financing and Inflation Drive Return Improvement: The company achieved a 13% regulated return in FY2026, with financing contributing 3.1% (approximately 80bps above the Ofwat model) and inflation contributing 3.8%. The AMP8 period assumes an average inflation rate of 3.0%; high inflation in the early stages supports returns, gradually declining later. The £800m equity placement ensures the leverage ratio remains within the 55%-65% target range. Incremental capital expenditure is concentrated in the 2026 regulatory reopening mechanism (£1.4bn), allocated to new housing, data centers, and green energy projects. Performance and Guidance: FY2026 revenue was £2.576bn, underlying EBIT was £1.06bn, and EPS was 107.1p, beating consensus by 4%. FY2027 guidance includes revenue of £2.7-2.8bn, capital expenditure of £2bn (£175m above consensus), and asset base growth of approximately 10%. Goldman Sachs slightly lowered FY2027-30 EPS forecasts by about 1%, but raised the target price from 1,346p to 1,523p due to higher RCV growth and return assumptions. Valuation and Rating Logic: Although the company benefits most from investment trends in the UK water sector, valuation offers limited upside. Additionally, the sector faces high interest rates, regulatory risks, and fewer investment opportunities compared to European peers, leading to a maintained neutral rating. The target price is based on a Sum-of-the-Parts (SOTP) valuation, with key risks being inflation and interest rate volatility.

Analysis framework

Goldman Sachs employed a regulated return bridge analysis to decompose the drivers of the company's 10%-11% return target (financing, inflation, operational efficiency) and evaluated long-term asset base expansion in conjunction with the AMP8 capital expenditure plan and RCV growth forecasts. For valuation, a Sum-of-the-Parts (SOTP) method was used, valuing core assets at a premium to RCV and calculating retail and other segments separately. The methodology emphasizes the impact of capital allocation efficiency and financing capabilities within the regulatory cycle on returns, incorporating macro variables (inflation, interest rates) into sensitivity analysis.

Methodology notes

• Valuation MethodSOTP Segment Valuation

  Sum-of-the-Parts Valuation

  Values different business segments (e.g., regulated assets, retail operations) separately and sums them up, suitable for diversified business structures. In this report, United Utilities' regulated assets are valued at a premium to RCV, while other businesses are calculated separately to derive total equity value.

• Industry/Sector Analysis Framework

  Regulated Return Bridge Analysis

  Quantifies the contribution of various factors to total returns by decomposing the components of regulated returns (e.g., base return, financing performance, inflation impact, operational efficiency). This report uses it to analyze the sources of the company's 200bps excess return, helping investors understand the driving logic.

• Macroeconomic framework

  Inflation and Interest Rate Sensitivity Analysis

  Assesses the impact of macro variables (such as CPIH inflation and interest rates) on regulated returns and valuation. This report notes that short-term inflation upside supports returns, but a subsequent decline may lead to diminishing returns, while interest rate changes also affect financing costs and valuation multiples.

  Comparison

  Compared to European peers, the UK water sector is less attractive

  Risks

  Inflation and interest rate volatility; uncertainty in Ofwat regulatory decisions

Impact & implications

The research report suggests that United Utilities' strategic upgrade will drive both asset base and return improvements. However, the UK water sector as a whole faces constraints from a high-interest-rate environment, regulatory uncertainty, and limited investment opportunities relative to European peers. Although the company is the biggest beneficiary of industry investment trends, the valuation upside is insufficient to support a higher rating. Investors should monitor Ofwat's final decision on the 2026 capital reopening mechanism (December 2026) and the continued impact of inflation and interest rate trajectories on returns.

Risks

• Lower-than-expected inflation leading to a decline in regulated returns
• Rising interest rates increasing financing costs and valuation pressure
• Ofwat approval for the capital reopening mechanism falling short of expectations
• Customer ODI penalties exceeding expectations, impacting returns

• Actual trajectory of inflation and interest rates during the AMP8 period
