ITM Power’s Retail Frenzy Meets a Reality Check as Three June Catalysts Loom

ITM Power was one of the most actively traded stocks among British retail investors last week, with Interactive Investor listing it among the top ten most-traded equities on its platform on Thursday, 28 May. Some 53% of transactions were buys, but Friday brought a harsh reversal as the shares closed at 194.40 pence, down 7.07%. The day opened at 216.00 pence and touched an intraday high of 217.60 pence before sliding as low as 192.30 pence on volume of 27.6 million shares.

The pullback capped a week that had seen the stock advance roughly 14.2% from the prior Friday’s close of 170.20 pence. Year to date, the gain stood at a staggering 212.04% — a rally that has largely been driven by improving sentiment around green hydrogen and energy security rather than fresh company news. No new regulatory filing accompanied the surge; the last official update was a routine monthly director share purchase on 18 May, in which Simon Bourne and Dennis Schulz each acquired 92 partnership and 92 matching shares at £1.6196 per share.

The week’s volatility was amplified by the rebalancing of the MSCI UK Small Cap Index, into which ITM Power was added at the end of May. Between the state-backed injection of £86.5 million from Great British Energy and the actual index rebalancing, the share price rocketed from 157.4 pence to an intraday peak of 219.8 pence. Passive index funds were forced to buy in the closing cross, while hedge funds used the liquidity spike to unwind short positions. The result was a sharp technical reversal that erased the index-driven gains. The final closing price before the rebalance was 209.20 pence, with the 52-week range spanning 48.05 to 217.60 pence.

Now the market’s attention shifts to a trio of binary events in June that will test whether the rally rests on fundamental progress or merely expectations. The first is the final investment decision on the Chronos electrolyser programme — a 2-MW system that triples output, cuts costs by 40% and halves the footprint compared to its predecessor. ITM’s new 1-GW Sheffield factory has already secured a £46.5 million grant from the UK energy department, spread across fiscal 2026/27 and 2027/28.

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

The second catalyst is the outcome of the UK’s second hydrogen allocation round, HAR2. Twenty-seven projects are on the shortlist, including Uniper’s Humber H2ub, where ITM is poised to deliver six 20-MW Poseidon modules. The round aims for 875 MW of capacity from 87 applications totalling 2.8 GW. The third is Uniper’s own approval for its 120-MW Killingholme project. A FEED contract was signed in June 2025, planning permission was granted by North Lincolnshire Council in March 2026, and Uniper is targeting a final investment decision in 2026.

Against this backdrop, ITM’s financials are improving but remain loss-making. First-half revenue for fiscal 2026 hit a record £18 million, with the full-year forecast raised to £40-43 million — up 35% year-on-year. The order book stands at £152 million, 71% of which is considered profitable. The EBITDA loss narrowed to £11.9 million in the first half from £16.8 million previously, and the full-year loss is expected between £27 million and £29 million. Net liquidity, bolstered by the Great British Energy funds, should end the year at £170-175 million.

A new revenue stream is emerging from the defence sector. ITM has partnered with Rheinmetall to produce synthetic fuels for NATO forces under the Giga PtX programme, which envisions hundreds of decentralised production sites across Europe, each with up to 50 MW of electrolysis capacity. The programme gives ITM exposure to a defence-driven hydrogen market that extends far beyond civilian applications.

Analysts remain divided. Of eleven covering the stock, seven rate it a buy, four a hold, and one a sell. Price targets span a wide 140 pence range. Jefferies rates it a buy with a target of 200 pence, while Morgan Stanley — which upgraded to overweight with a 170 pence target in its first positive rating on a UK hydrogen stock since 2021 — expects no operating profit before 2028. Berenberg also rates it a buy but at a significantly lower target of 110 pence, while UBS holds a neutral rating with a fair value of just 60 pence.

ITM Power at a turning point? This analysis reveals what investors need to know now.

Technically, the stock remains in a bullish configuration despite cooling momentum. StockAnalysis showed the 50-day moving average at 119.43 pence and the 200-day at 81.92 pence, with the relative strength index at 76.95. Investing.com’s pivot stood at 207.34 pence, with first resistance at 211.06 pence and third at 216.63 pence. Support is pegged at 150.9 pence and resistance at 224.25 pence. The key question is whether the shares can rebuild momentum toward the 217.60 pence high and beyond, or whether profit-taking drives them back toward the 50-day average near 178.86 pence.

The coming weeks carry the weight of three decisions. If all go in ITM’s favour, the stock’s elevated base may be validated. If any stumble, the 212% year-to-date gain will look increasingly like a sugar high. The next official update comes on 15 September 2026 with the full-year results, by which time the June milestones should have provided a verdict on whether the operational turnaround is translating into sustainable growth.
