Latest Results

Pennon reported results for the year ended 31 March 2026 on 10 June 2026. The company returned to profit, helped by higher regulatory allowances, improved cost management and stronger water consumption. Return on regulated Equity was 6.7%, with outperformance on financing and totex partly offset by penalties on outcome delivery incentives. Storm overflow use fell 17%, with spill duration down about 25%.

New chief executive Keith Haslett, who joined on 1 April 2026, said results showed a positive shift in profitability but that performance must improve on Customer Service and environmental commitments. He launched an operational review.

Dividend Decision

The board recommended a final dividend of 20.03p, giving a total dividend per share of 29.29p, down from 31.57p. Total dividends rose to £138.2m from £133.7m, reflecting a larger number of shares after an equity raise. The 2025/26 dividend reflects the 2024/25 base increased by CPIH of 3.4%. Shares fell after the results as investors focused on the lower per-share figure.

Dividend Policy

Pennon's policy to 2030 is for the base dividend to grow in line with CPIH. This links payouts to Inflation and the regulated asset base, providing visibility for income investors.

Cash Flow and Balance Sheet

Water companies are investing heavily under the current regulatory period, and Pennon is no exception. Group capex was £644m, with guidance of £710m to £740m for the year, front-loaded in the water business. Net debt increased to £4,379.6m from £3,936.2m. Water group gearing was stable at 61.8%. Free Cash Flow is negative during this Investment phase, so dividends are funded partly through debt, supported by the growing regulated asset base.

Regulatory Risk

UK water companies face intense scrutiny over pollution and customer service. South West Water was recently fined £1.8m for a drinking water offence linked to a parasite outbreak in Brixham in 2024. Penalties and future regulatory reforms could affect returns.

Operational Performance

Water quality performance remains strong, with sector-leading results at SES Water and a top-quartile position at South West Water. Water resources exceeded target at 98%, helped by investment in storage resilience and high rainfall, despite South West England receiving around 150% of average rainfall in November and December. These operational metrics matter because regulatory rewards and penalties directly affect returns and, ultimately, dividend capacity.

Growth of the Regulated Asset Base

Heavy Capital Investment expands Pennon's regulated asset base, which drives future allowed revenues. Although this investment raises debt today, it supports long-term Earnings growth and the CPIH-linked dividend over time.

Risks

Risks include regulatory penalties, higher interest costs, operational incidents and political pressure on the sector. Rising debt also requires careful management.

Market Sentiment

Investor sentiment has been cautious, with commentary focusing on the dividend reduction and regulatory challenges. Some investors see value in the regulated asset base and inflation-linked dividend.

How PNN Fits an Income Portfolio

Pennon offers inflation-linked income from essential infrastructure, but with higher regulatory and political risk than in the past.
