Ceres Power Holdings PLC (LSE:CWR, OTC:CPWHF) shares rose 2.6% to 640p on Thursday, extending a remarkable run that has seen the Horsham-based clean energy technology developer's stock more than double in the past month, valuing the company at £1.24 billion.
The immediate catalyst was the announcement of an infrastructure partnership between Delta Electronics and Centrica, targeting the data centre market and energy-intensive industries across the UK and Europe, with solid oxide fuel cells (SOFCs) providing off-grid energy generation.
SOFCs are electrochemical devices that generate electricity directly from fuel, offering high efficiency and lower emissions than conventional power generation.
Delta Electronics is one of Ceres' manufacturing licensees, building solid oxide fuel cell stacks and systems based on Ceres technology, while Centrica holds a strategic partnership with Ceres to accelerate SOFC deployment.
The deal positions Ceres' technology at the intersection of two of the most powerful demand trends in the European energy market: the rapid growth of data centre power consumption and the push for cleaner, decentralised energy infrastructure.
Ceres itself is not a direct contractual party to the Delta-Centrica agreement, and the announcement disclosed no financial terms, volumes, or deployment timelines.
The partnership nonetheless supports what Ceres describes as a licensing-led revenue model, under which commercial roll-outs by manufacturing partners generate royalty income for the company rather than requiring direct capital deployment.
Peel Hunt, however, retained a 'sell' recommendation on the stock with a 200p target price, arguing that the share price has run well ahead of near-term execution visibility.
The broker said its cautious stance reflects timing and valuation considerations rather than any lack of conviction in the underlying technology, describing Ceres as a high-quality platform with credible partners and a robust intellectual property position.
Peel said the market appears to have shifted from underwriting long-term optionality to pricing it in today, with the current valuation implying an acceleration in commercial scale, royalty income, and cash generation that exceeds what the broker believes is visible in the near term.
