United Utilities (UU), a water utility in north-west England, experienced an 11% surge in its share price following a successful £800 million share issuance and positive updates from the water regulator Ofwat. UU is targeting a return on equity of 10-11%, which is higher than previous guidance, and plans to request an additional £2.5 billion for infrastructure improvements, which could raise household bills by £10. This comes as Ofwat's recent regulatory settlement has made water bills across England and Wales more favorable for certain companies, particularly those not facing significant fines for pollution. Severn Trent, operating in the Midlands, also saw its shares rise by 7% in response to UU's performance, indicating a broader investor confidence in the sector. Both UU and Severn Trent are now at all-time highs in share value, contrasting sharply with the ongoing crisis at Thames Water. The situation underscores a shift in regulatory dynamics that may favor well-performing utilities, suggesting that international investors remain interested in the sector despite challenges faced by some companies.
