Simply Wall St · 2d ago

United Utilities Group (LSE:UU.) is back in focus after reporting reservoir storage across its network well below seasonal averages, with key Cumbrian sources such as Haweswater and Thirlmere at 42.5% compared with a typical 64.1%.

Recent news around reservoir stress sits against a share price that has climbed, with a 30-day share price return of 9.39% and a year-to-date share price gain of 19.73% at a current level of £14.44. The 5-year total shareholder return of 81.48% points to momentum that has been building over a longer horizon.

The share price has sprinted ahead while headlines focus on reservoir strain and heavy investment commitments. Does United Utilities Group still offer an appealing trade off between risk and reward at £14.44, or has the easy upside gone?

Most Popular Narrative: 4% Undervalued

On the most followed view, United Utilities Group screens as modestly undervalued, with a fair value of £15.12 set against the latest close at £14.44 and a discount rate of 7.56% applied to those future cash flows and earnings assumptions.

The enlarged AMP8 capital plan of around £11.5b, including significant spend on asset health and projects such as the Lake Windermere programme, is expected to increase the regulated asset base and, in time, to support higher allowed revenue and earnings.

Ofwat’s new annualised totex re-opener process and the recent draft decision that allowed £975m of year one re-opener totex, with most of the asset health and Windermere submissions included, point to a mechanism for United Utilities Group to secure further growth capex during AMP8 that can feed into revenue and earnings in later years.

Result: Fair Value of £15.12 (UNDERVALUED)

Still, the story around United Utilities Group could shift quickly if credit ratings move from negative outlook to a downgrade or if rising operating costs outpace allowed revenue.
