The Ceres Power share price has fallen roughly 37% over the past month, making the solid oxide fuel cell developer the worst performer on the FTSE 250 during that stretch. By midday on 17 July, the stock was down a further 5% on the session.
The decline comes despite the company making no fresh stock exchange announcements. There has been no profit warning, no contract cancellation, and no regulatory action.
The £103m Fundraising and What Followed
The most plausible trigger is the capital raise completed in early June. On 10 June 2026, Ceres issued 18,000,000 new ordinary shares at 570p each, raising £103m in aggregate, according to the company’s results of capital raise announcement on Investegate. The offer price represented a discount of approximately 6.5% to the previous day’s closing price and diluted existing shareholders by around 9.2%.
The raise was led by Berenberg and UBS. The placing alone accounted for roughly £101m, with a retail offer and director subscriptions making up the balance. Chief executive Phil Caldwell and four non-executive directors participated. New shares were admitted to trading on the London Stock Exchange on 12 June 2026, according to Yahoo Finance.
The offer was oversubscribed. Ceres said at the time that ‘the new funds present a clear opportunity to capitalise on commercial momentum for Ceres technology and ensure we are well placed for the future.’
Post-placing share price weakness is not unusual. Some investors who bought ahead of the raise, or participated in the placing at 570p, may have since sold. At the current price, the placing price sits around 58% above where the stock trades today.
AI Data Centres: The Strategic Case Behind the Raise
Ceres pointed to growing demand from artificial intelligence and data centres as a key driver of the fundraising. The company argued its solid oxide fuel cell technology is ‘increasingly recognised as a credible solution to the “behind the meter” power gap’ as grid connections face lengthy delays, according to Proactive Investors. The proceeds are intended to strengthen the balance sheet and help manufacturing partners scale up production.
Ceres operates a capital-light, licence-based model: it licenses the manufacturing of its cells to third parties rather than building them itself. Royalties accrue when those partners sell cells to end customers. The group’s near-term revenue trajectory depends heavily on whether its partners in Asia can convert pipeline into orders.
The company was spun out of Imperial College in 2001 and has not yet reached profitability. The fundraising was necessary partly because of that: pre-raise, Ceres reported cash and short-term investments of £104.1m as of 30 June 2025 (unaudited), comprising £56.6m in cash and equivalents and £47.4m in short-term investments, per the group’s interim results for the period ended 30 June 2025.
Sector Pressure and Major Shareholders
Ceres is not alone in suffering. US peers Bloom Energy and FuelCell Energy have also seen their share prices fall since June, and ITM Power has come under pressure in London. The pattern points to a sector-wide concern about the pace of technology adoption rather than a Ceres-specific issue.
Short-selling disclosures filed with the Financial Conduct Authority show some investment firms have borrowed Ceres shares in anticipation of further falls, though the level of activity does not appear unusual relative to the stock’s history.
The two largest shareholders provide a degree of strategic anchor. As of the 2024 annual report, Weichai Power (Hong Kong) International Development Co. Ltd held 37,965,262 ordinary shares, equivalent to 19.60% of issued share capital, and Robert Bosch GmbH held 33,790,880 shares, or 17.45%. Both are industrial manufacturers with a strategic interest in fuel cell commercialisation rather than short-term financial returns.
Despite the recent decline, Ceres remains the best performer on the FTSE 250 since July 2025. The question for investors is whether the current price reflects a reset after a strong run, or the start of a more sustained rerating downward.
The next material test will be whether the company’s Asian manufacturing partners can report commercial traction. Any royalty revenue announcement from that channel would be the clearest signal yet that the technology is moving from development into deployment at scale.
