ITM Power's 200% Surge: The BlackRock Miss, the CMA Nod, and the Valuation That's Stretched
03.06.2026 - 15:03:02 | boerse-global.de
For a stock that has nearly tripled since January, ITM Power is drawing attention from an unusual source: a major British fund that doesn't own a single share. The BlackRock Smaller Companies Trust, in its April portfolio update published on 2 June, flagged ITM Power as the second-largest performance detractor among stocks it did not hold. The jargon term is an "off-benchmark detractor" — a rising share price that the trust missed out on, denting its relative returns. The fund’s net asset value per share advanced 7.0% in April, while the Deutsche Numis Smaller Companies plus AIM index gained 7.1%.
The catalyst for that April climb is well documented. On 9 April, ITM Power announced a total funding package of £86.5 million: £40 million from Great British Energy and a pledged grant of £46.5 million from the UK Department for Energy. The money will finance an automated production line capable of turning out 1 GW of the company’s new Chronos electrolyser stack. The subsidy hurdle is now cleared — the Competition and Markets Authority confirmed on 20 May that its Subsidy Advice Unit had closed the case, with the grant to be disbursed in fiscal years 2026/27 and 2027/28. Great British Energy, which already holds a 10.41% stake following the capital injection, has become a state anchor shareholder that structurally alters the company’s profile.
Investor appetite is not limited to institutions. Data from Interactive Investor shows ITM Power ranked fourth among the most-bought ISA stocks in the week to 29 May — its highest placement since mid-April. On 1 June, it was among the platform’s ten most-traded securities, with 68% of transactions being buys. The retail crowd is returning.
Yet the valuation debate is intensifying. Analysts have lifted their price target from £0.95 to roughly £1.19, a 26% increase, but the shares currently trade at 184.50p — well above that level. Some fair-value models put the stock more than 50% above its intrinsic worth based on current cash-flow projections. The forward price-to-earnings ratio stands at 170.53, reflecting extreme growth expectations. The projected profit margin has slipped slightly to 5.43%, while the discount rate applied in valuations has risen to 10.29%.
Should investors sell immediately? Or is it worth buying ITM Power?
ITM Power has broadened its narrative beyond green hydrogen. A strategic partnership with Rheinmetall, announced 17 April, targets the "Giga PtX" project: a Europe-wide network of decentralised plants producing synthetic fuels for NATO forces. The plan envisions several hundred sites, each with up to 50 MW of electrolysis capacity and an annual output of 5,000 to 7,000 tonnes of e-fuel, with the initial focus on the UK. That adds an energy-security and defence angle that played well into the April rally for UK small-caps, according to BlackRock.
Insider confidence is also in evidence. CEO Dennis Schulz and Simon Bourne each purchased 92 shares at 162p in mid-May, bringing total insider ownership to 8.73%. Meanwhile, a ten-year service contract with MorGen Energy for the 20 MW West Wales Hydrogen project, due online in 2028, adds operational visibility.
The broader market tailwind from UK renewable energy remains supportive. A record auction recently awarded contracts for nearly 5 GW of solar capacity, a development that could boost demand for grid-friendly electrolyser solutions. The global hydrogen market is projected to reach $1.45 billion by 2034.
ITM Power at a turning point? This analysis reveals what investors need to know now.
But headwinds persist. High production costs and a lack of international standards continue to restrain the sector. For ITM Power, the story is compelling, but the share price has run far ahead of the fundamentals. The real test will come when the Chronos production line begins to deliver meaningful revenue — the company has already lifted its FY26 sales guidance, but execution is everything. Whether the valuation can justify a near-200% year-to-date rally depends entirely on the numbers that land in the quarters ahead.
