ITM Power’s Retail Rally Collides with Institutional Mandate Ahead of Pivotal June

Retail investors pushed ITM Power shares 7.7% higher to £2.10, hitting a fresh 52-week high. Upcoming catalysts include MSCI inclusion, Chronos FID, and HAR2 award that could sustain the rally.

Retail investors on the interactive investor platform drove ITM Power shares to a fresh 52-week high on Thursday, with 53 per cent of trades in the stock registering as buys. The surge pushed the electrolyser maker’s equity to £2.17 at one point before closing at £2.10 — a gain of 7.7 per cent on the day — placing it among the platform’s most-traded names alongside blue-chips such as Rolls-Royce, BP, BT Group and easyJet.

The move came without any fresh company announcement — the last corporate filing dates back to 18 May — and appears to be purely driven by retail momentum. The day before, the stock had already touched a 52-week high of 194.70 pence, or roughly £1.95, with trading volumes of 9.7 million shares well above the average. But Thursday’s rally extended that peak, underscoring how much the narrative around the Sheffield-based hydrogen specialist has shifted from its year-low of 46 pence.

Behind the scenes, however, a trio of structural catalysts is lining up that could give the rally more fundamental backing. The most immediate is ITM Power’s inclusion in the MSCI United Kingdom Small Cap Index, effective after the close on 29 May. The rebalancing forces passive funds to buy the stock, raising visibility among institutional investors at a time when the company’s market capitalisation sits at around £1.1 billion.

June brings a series of binary decisions. The final investment decision on the Chronos electrolyser programme is due — a 2-MW-per-unit system that triples the output of its predecessor while cutting costs by 40 per cent and halving the physical footprint. The new 1-GW factory in Sheffield, which has already secured a £46.5 million capital grant from the UK government’s Department for Energy Security and Net Zero (disbursed across fiscal 2026/27 and 2027/28), is designed to ramp up production of the next-generation platform. That grant followed a £40 million equity injection from Great British Energy in April.

Separately, the second UK hydrogen allocation round, HAR2, has 27 projects on its shortlist, including Uniper’s Humber H2ub, for which ITM Power is nominated to supply six 20-MW POSEIDON modules. A positive outcome would add further weight to an order book already standing at £152 million, 71 per cent of which management classifies as profitable. Uniper’s own FID is expected later in the year, creating another potential trigger.

Further out, ITM Power is cooperating with Rheinmetall on the Giga-PtX project — a planned Europe-wide network of decentralised e-fuel plants targeting NATO supply chains. Each facility would have up to 50 MW of electrolysis capacity and produce 5,000–7,000 tonnes of fuel annually, starting in the UK.

The financial backdrop is improving but still loss-making. Revenue is forecast to rise 35 per cent in the current year to between £40 million and £43 million, while the EBITDA loss of £27 million to £29 million is narrowing. Net cash of roughly £200 million provides a solid cushion.

Analyst opinion remains deeply fractured. Jefferies recently raised its price target to 200 pence, and Morgan Stanley upgraded the stock to Overweight — the first positive rating on a UK hydrogen name since 2021. Berenberg sticks at Buy with a far lower 110 pence target, while UBS assigns the shares a Neutral and a fair value of just 60 pence. The 140-pence spread reflects the uncertainty surrounding a sector that still depends on subsidy decisions and project timelines.

ITM Power reports full-year results on 15 September. By then, the Chronos FID, the HAR2 outcome, and possibly Uniper’s investment green light all will have crystallised. For retail investors who piled in this week, those updates will determine whether the momentum becomes a lasting trend or fades into profit-taking.
