Water utility firm Pennon said on Tuesday that underlying earnings had grown 55% year‑on‑year in the six months ended 9 March, despite ongoing weather‑related cost pressures and higher early‑cycle regulatory costs.

As a result, Pennon said underlying profitability was now expected to be within the range of market expectations, albeit at the lower end of forecasts.

Pennon said it was targeting a 7% return on regulated equity over K8, the five-year price control period running to 2030, with financing and capex efficiencies in FY26 partly offset by net outcome delivery incentive (ODI) penalties.

Wastewater performance continued to improve, with around a 40% reduction in pollutions, a 55% fall in normalised pollutions, and a 17% drop in storm‑overflow use, though exceptional rainfall was still expected to result in a net ODI penalty for the year.

The FTSE 250-listed firm added that its Pennon Power unit now has two renewable generation sites in operation, contributing to group energy needs, while regulatory investigations were said to be progressing towards expected conclusions in 2026.

As of 0850 GMT, Pennon shares were up 3.64% at 555p.
