ITM Power’s Cash Hoard and Two Catalysts Collide as 400% Rally Faces Its Toughest Test

ITM Power shares surged 400% in a year. With a government subsidy verdict and MSCI Small Cap inclusion due, the hydrogen stock faces its biggest test. Insider moves and analyst divisions add to the drama.

The next ten days will determine whether ITM Power’s staggering twelve-month surge — roughly 400% — has real staying power or is simply riding on hope. Two events bookend the final week of May: a government subsidy ruling on the 26th and the firm’s inclusion in the MSCI UK Small Cap Index on the 29th. Together, they represent the sharpest test yet for a stock that has already pushed its market capitalisation back above £1.11 billion.

Investors have been piling into the hydrogen specialist despite a loss-making present. The pre-tax deficit widened to £45.4 million in the year to April 2025, up from £27.1 million a year earlier. Yet the company is sitting on a cash pile of £197.8 million, giving it ample runway to fund the factory expansion it hopes will finally turn the dial toward profitability.

A grant decision that could unlock a factory upgrade

The Subsidy Advice Unit, part of the UK’s energy department, is due to publish its verdict on a planned £46.5 million grant for ITM’s Sheffield site on 26 May. The money would back the construction of Chronos, an automated production line with a capacity of one gigawatt a year. State-backed Great British Energy has also signalled its willingness to inject £40 million as part of the same package.

ITM says Chronos will triple output and cut manufacturing costs by 40%. A green light from the regulator would let management take a final investment decision in June. Without it, the company’s path to scaling its Neptune V electrolyser remains far less certain.

Three days later, on 29 May, MSCI’s index changes take effect. Inclusion in the small-cap gauge should trigger mandatory buying from passive funds that track it. That technical demand is already visible: trading volumes on some days have been as high as 13.2 million shares, 168% above the average, while the price has touched 174.80 pence. Short sellers, however, are not running for cover — only 2.92% of the float is currently shorted, a level that has barely budged during the rally.

Insider moves tell a story of two management camps

Inside the company, confidence is less uniform than the share price suggests. Chief technology officer Simon Bourne exercised options on 1.33 million shares last month and then sold 872,738 of them at an average price of 157.44 pence. ITM described it as a “sell-to-cover” transaction to meet tax obligations. Bourne still holds 656,570 shares, representing about 0.095% of the issued capital.

Chief executive Dennis Schulz is taking a very different approach. His 1.3 million shares are subject to performance conditions: they vest only when ITM wins profitable contracts and the new Chronos line in Sheffield starts production on schedule. That lock-up sends a signal to the market that management’s own financial incentives are aligned with delivering operational milestones, not just a higher stock price.

Analysts split between enthusiasm and caution

The gulf in analyst views reflects the disconnect between the rally and the underlying numbers. Morgan Stanley has lifted ITM to “Overweight” with a price target of 170 pence, forecasting an operating break-even in the 2028 financial year. Jefferies has set a more ambitious target of 200 pence, but warns of a lopsided risk profile: 52% downside in a negative scenario versus 37% upside in a positive one. UBS stays at “Neutral” with a target of just 60 pence, arguing that the valuation has run far ahead of fundamentals.

Operationally, progress is visible but still shallow. First-half revenue hit a record £18 million, and management raised its full-year guidance to between £40 million and £43 million. The order book stands at £152 million, with 71% of contracts deemed profitable — a sign that the project quality is improving. EBITDA break-even, however, is not expected before 2028. Jefferies shares that timeline.

A june trading update will settle the debate

Beyond the two dates in May, several other potential catalysts sit on the horizon. The UK’s Hydrogen Allocation Round 2, Uniper’s proposed 120-megawatt Humber H2ub project, and the cooperation with Rheinmetall on synthetic fuels in Europe all add to the narrative. But none of them will matter as much as the first trading report after the rally.

If the June update shows strong Chronos orders and clear progress in Sheffield, the premium baked into the stock may be justified. If not, the current price is mostly a bet on future promise — and that kind of bet can unwind as quickly as it built.
