ITM Power's Breakout Month: Defence Contracts and Upgraded Guidance Fuel a 450% Rally

ITM Power hits multi-year high after £40M government defence contract, revenue guidance upgrade, and improved cash reserves, though analysts remain cautious.

The hydrogen sector has a new standout performer. ITM Power, the British electrolyser specialist, has seen its shares surge to levels not witnessed in years, propelled by a potent combination of government-backed defence contracts and a sharply improved financial outlook.

Shares hit a multi-year peak of 166.50 pence on April 27, before settling around the 153 pence mark. That represents a staggering recovery from the 52-week trough of just 30 pence, handing the company a market capitalisation of roughly £879 million. Trading volumes have exploded alongside the price action, with more than 16 million shares changing hands daily — well above historical averages and a clear sign that institutional investors are piling back in.

A £40 Million Pivot to Defence

The immediate catalyst for this month's rally was a £40 million injection from the British government into the so-called "Giga-PtX Project." ITM Power is collaborating closely with German defence contractor Rheinmetall to deploy 50 megawatts of PEM electrolysers for the decentralised production of synthetic fuels tailored to NATO applications. The move represents a strategic pivot into military logistics, opening up an entirely new revenue stream beyond the traditional energy markets.

This defence-sector foray comes at a time when the UK government is throwing its weight behind clean energy infrastructure. A record £1.5 billion budget has been approved for the next auction round, with £1.1 billion earmarked for offshore wind, £185 million for onshore wind and solar, and £270 million for emerging technologies like tidal power. For ITM Power, this capacity build-out is seen as the bedrock of a functioning domestic hydrogen economy.

Guidance Upgrade and a Stronger Balance Sheet

Beyond the defence deal, management has lifted its revenue guidance for the current financial year to as much as £43 million, citing improved project execution and a swelling order book that now stands at £152 million. Cash reserves are also looking healthier than anticipated. The company now expects to close the period with over £210 million in the bank, up sharply from earlier projections, thanks to strategic capital inflows and tight cost controls as it transitions to series production.

The path to profitability remains the central challenge, however. ITM Power posted a loss per share of £0.023 in the first half, which — while beating market expectations by more than 90% — still leaves the company in the red for the full year as it continues to expand production capacity globally.

Analysts Remain Cautious Despite the Momentum

The market's enthusiasm is not universally shared on the Street. Berenberg Bank maintains a "Buy" rating but with a price target of just 110 pence — well below current levels. UBS Group sits at "Neutral" with a 60 pence target, while the consensus sits at "Moderate Buy" with an average target of 95 pence. The stock is now widely considered overbought after its 100% gain in April alone, raising the spectre of profit-taking in the near term.

The contrast with peers is stark. Norwegian rival Nel ASA reported a 73% plunge in order intake and a net loss of 144 million Norwegian kroner for the latest quarter, with revenue sliding to 148 million kroner. Meanwhile, Clean Power Hydrogen (CPH2) has taken a different route, signing a non-binding ten-year memorandum of understanding with BKW's ABE Group unit for 175 megawatts of membrane-free electrolysers.

For ITM Power, the immediate task is defending its newfound valuation. The Rheinmetall partnership provides a tangible industrial application for its PEM technology beyond green energy markets, but the stock's overbought status signals elevated downside risk as the market digests the recent surge.
