Plug Power's Order Book Is Filling Up, but the Tape Tells a Different Story

Plug Power delivered a 1MW electrolyser to New Zealand and won a 50MW Australian contract, but the stock trades 57% below its 52-week high.

Plug Power closed Friday's session at EUR 1.73, and the gap between what the company keeps announcing and what investors are willing to pay for it has rarely looked wider. The hydrogen specialist is stacking up electrolyser wins on two continents while its share price drifts, pinned down by forces that have little to do with its order pipeline.

A Megawatt Goes to Invercargill

On Tuesday, Plug Power confirmed delivery of a one-megawatt GenEco PEM electrolyser to HWR Hydrogen, a division of H.W. Richardson Group Limited. The unit is headed for a refuelling station in Invercargill, New Zealand, where it will serve a fleet of heavy trucks running on a combined hydrogen-diesel setup.

It is a modest installation by the standards of utility-scale hydrogen, but it puts the company's hardware into a live commercial setting rather than a feasibility study. Earlier, Plug Power had also flagged its involvement in a sustainable aviation fuel project in Uzbekistan, where systems totalling up to 2.4 gigawatts are envisaged down the line.

Australia's Largest FID-Backed Project

The bigger prize sits across the Tasman Sea. Orica has selected Plug Power to supply a 50-megawatt GenEco PEM electrolyser system for the Hunter Valley Hydrogen Hub. That development ranks as Australia's largest renewable hydrogen project to have reached a final investment decision, with an expected output of roughly 4,700 tonnes of renewable hydrogen per year.

Taken together, the New Zealand delivery and the Australian contract suggest demand for electrolysers is real and not merely rhetorical. What they do not do, at least so far, is move the stock.

A Corner-Office Departure Lands Mid-Delivery

Complicating the picture is a change at the operational helm. On 17 September, Chief Operating Officer Dean C. Fullerton notified Plug Power that he will leave the company effective 23 October 2026 to take a role elsewhere. A mandatory filing with the US Securities and Exchange Commission states the departure did not stem from any disagreement with the company, and management has pointed to a structured handover of his responsibilities.

Even so, the timing invites scrutiny. Losing a senior operations executive while multi-year supply contracts are being executed raises legitimate questions about continuity, and the market tends to price that uncertainty quickly. Whether the transition runs smoothly will ultimately be judged against upcoming delivery schedules rather than press releases.

The Macro Tape Overrides the Micro Wins

For all the operational noise, the dominant force on the share price remains the cost of capital. Media reports attributed Thursday's 3.92% slide — which came alongside weakness across other fuel-cell makers — largely to elevated US Treasury yields weighing on the entire sector. For a capital-intensive growth business, refinancing costs and investment risk carry more weight with many market participants than incremental project announcements overseas.

The chart reinforces the point. Plug Power trades 19% below its 200-day moving average of EUR 2.14, and 57% below its 52-week high of EUR 4.04. Sentiment has not been helped by recent analyst activity either: Jefferies upgraded the stock roughly three weeks ago, and it has since lost 7.2%. A management appearance at a Jefferies investor conference about two weeks back failed to spark a lasting turn, with the shares shedding a further 5.0% afterwards.

What Has to Happen Next

Plug Power has now demonstrated, through deliveries to New Zealand and a flagship contract in Australia, that its electrolyser technology is finding its way into real projects. The harder test is execution at scale — converting a growing backlog into predictable revenue while navigating a rate environment that continues to punish long-duration growth stories.

Until bond markets ease and the company shows it can accelerate its larger undertakings without missing a beat, the burden of proof stays squarely on the operational side of the business.
