ITM Power’s Three-Pronged June: Index Inclusion, Government Grant, and a NATO Fuel Link

ITM Power enters MSCI Small Cap, secures £46.5M grant for Sheffield line, and awaits June hydrogen auction results, Uniper decision, and new defence partnership with Rheinmetall.

For ITM Power, the calendar is stacking up in a way that could define the company’s trajectory for years. After closing May with a formal entry into the MSCI United Kingdom Small Cap Index, the British electrolyser maker now faces a June packed with binary outcomes — a government-backed investment decision, a major hydrogen auction result, and a green light from energy giant Uniper. Add in a freshly minted defence partnership with Rheinmetall, and the picture for the hydrogen specialist is suddenly far broader than its traditional clean-energy niche.

The index inclusion, effective after the bell on 29 May, obliges passive funds and ETFs tracking the MSCI benchmark to add ITM shares to their portfolios. For a company valued at roughly £1.11 billion, that mechanical buying pressure is substantial. Less quantifiable but equally important is the visibility lift: belonging to an MSCI index puts ITM on the radar of international institutional investors who use the index as a screening tool.

Just days before that technical catalyst, the UK government confirmed a £46.5 million grant for ITM’s flagship project — a fully automated production line in Sheffield dedicated to the next-generation Chronos electrolyser. Each Chronos unit delivers 2 MW, triple the output of the current system, at 40% lower cost and half the footprint. Management intends to take the final investment decision (FID) immediately after the grant notification, with commercial operations targeted for 2028.

That Sheffield line is the core of ITM’s turnaround strategy, and the grant removes a key uncertainty. Some analysts had previously flagged a worst-case scenario that could have lopped 52% off the share price. Now, with funding secured, the focus shifts to execution.

June also brings two additional inflection points. The UK government is expected to announce the results of its second hydrogen allocation round (HAR2). Among the 27 shortlisted projects is Uniper’s Humber H2ub site, where ITM is poised to supply six 20 MW POSEIDON electrolyser modules. Uniper’s own FID is anticipated before year-end, and planning permission is already granted. Separately, ITM has struck a strategic partnership with defence contractor 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 initial focus is on the UK.

On the financial side, the operational progress is tangible. First-half revenue for fiscal 2026 hit a record £18 million, and full-year guidance has been raised to £40-43 million — a 35% increase year-on-year. The order book stands at £152 million, with 71% of those contracts considered profitable, a marked improvement from the loss-heavy legacy business. The EBITDA loss narrowed to £11.9 million in the first half from £16.8 million a year earlier, though the full-year EBITDA loss is expected to land between £27 million and £29 million. Net cash, bolstered by funds from Great British Energy, is estimated at £170-175 million by year-end — providing ample runway.

Analyst opinion remains sharply divided. Of the eleven analysts covering the stock, seven rate it a buy, four a hold, and one a sell. Price targets span a remarkable 140 pence: Jefferies sees 200 pence (buy), Morgan Stanley lifted its rating to overweight at 170 pence — the first positive rating on a UK hydrogen stock since 2021 — Berenberg has 110 pence (buy), and UBS sits at 60 pence (neutral). Jefferies does not expect positive EBITDA before 2028 at the earliest, a view Morgan Stanley shares, contingent on flawless execution.

The share price has already absorbed much of the optimism. Over the past three months, ITM’s London-listed shares surged 164%, outpacing peers Ballard Power (+163%), Plug Power (+105%), and NEL ASA (+70%). But profit-taking has followed: in a recent session, the stock fell 7.4% to 143.30 pence on volume of 13.2 million shares, making ITM the most-sold stock on the AJ Bell platform that day. Short interest meanwhile dropped 40.3% between 15 and 30 April to just 18,761 shares.

All eyes are now on 15 September 2026, when ITM Power will report its full-year results. By then, all three June decisions could be resolved — Chronos FID, HAR2 contract awards, and Uniper’s go-ahead. The market would then receive a comprehensive picture of whether the operational turnaround is translating into sustainable growth.
