How an Ex-Rolls-Royce Chief's Bet and a ÂŁ46.5m Subsidy Pause Are Shaping ITM Power's Wild Ride

Sheffield electrolyser maker ITM Power sees director buy from ex-Rolls-Royce boss, NATO fuel partnership, but stalled subsidy and 43% drop from highs keep volatility high.

The hydrogen sector has never been for the faint-hearted, but few stocks encapsulate the sector's extremes quite like ITM Power. With annualised volatility of roughly 113%, the Sheffield-based electrolyser maker is currently a study in contrasts: a director buy from a former Rolls-Royce boss, a landmark defence-sector partnership, and a stalled government subsidy that threatens to delay a critical expansion — all while the shares have roughly doubled since January.

The stock changed hands at €1.46 on Monday, slipping 1.7% from Friday's close of €1.48. That leaves it 43.5% below the 52-week high of €2.58 reached on 29 May, but still 125% above the February trough of €0.65. The tug of war between profit-taking and structural optimism is laid bare in the charts: the shares trade well below the 50-day moving average of €1.74, yet remain comfortably above the 200-day line at €1.06. The 100-day average at €1.30 acts as the next substantive floor if selling pressure resumes.

The Insider Vote of Confidence

On 30 June, Sir Warren East — the former chief executive of Rolls-Royce and ARM — acquired 172,000 shares in the company for roughly £197,000. The transaction, disclosed via a mandatory director-dealing notice to the London Stock Exchange, represents his only holding in ITM Power. Insider purchases at a stock trading more than 43% off its highs are rare, and the move has not gone unnoticed by market watchers. East’s conviction comes as the company’s relative strength index sits at a neutral 45.7, suggesting no extreme overbought or oversold conditions.

Should investors sell immediately? Or is it worth buying ITM Power?

The NATO Fuel Contract and Operational Lift

Beyond the insider signal, ITM Power has secured a cooperation agreement with German defence group Rheinmetall to supply electrolyser capacity of up to 50 MW for the Giga-PtX programme. The aim is to produce synthetic fuels to NATO standards across several hundred planned plants, each with up to 50 MW of electrolysis capacity, churning out an estimated 5,000–7,000 tonnes of e-fuel annually. Rheinmetall brings its power-to-X expertise, while ITM supplies its ALPHA-50 electrolyser units. The deal initially targets the British market, though concrete revenue streams depend on partner Protium Green Solutions securing power supply, permits, and distribution infrastructure.

The core business, meanwhile, is showing tangible progress. The order book has swelled to £152m, and first-half revenue hit a record £18m. Critically, the quality of those orders is improving: the share of profitable contracts rose from 60% in April 2025 to 71% today. However, 29% of older projects still need to be converted into revenue within the next 18 months. Management has lifted its revenue guidance for fiscal 2026 to a range of £40m–£43m, underpinned by standardisation around the 50 MW ALPHA-50 platform for large-scale projects. The company holds cash and equivalents of £197.8m and burned just £9.2m over the past twelve months.

The ÂŁ46.5m Hurdle

Yet for all the encouraging fundamentals, the next major catalyst — and the biggest risk — is regulatory. ITM Power is awaiting a £46.5m grant from the UK Department for Energy Security and Net Zero. The subsidy is currently stuck at the Subsidy Advice Unit of the Competition and Markets Authority (CMA). Without the green light, the company cannot build the new automated, gigawatt-scale production line that underpins its entire expansion plan. In the second quarter of 2026, Great British Energy already took a 10.4% stake for £40m as part of the same subsidy package, underscoring the government’s interest — but the formal decision remains pending.

The market is effectively pricing in both the upside of a successful resolution and the downside of a delay. Until the CMA clears the decks, the shares are likely to remain in a consolidation phase, waiting for the next significant directional impulse. For a stock with 113% annualised volatility, that impulse could be sharp — for better or worse.
