Has Plug Power (PLUG) Fallen Far Enough To Justify Its Sales Valuation?

Listen to the news

Plug Power has been busy signing new electrolyzer deals and expanding its hydrogen footprint, yet the share price has fallen sharply over recent years, which puts a spotlight on whether today's valuation still lines up with its sales base.

  • Plug Power shares have fallen 92.8% over the past 5 years, which raises a clear question about how much revenue investors are currently paying for.
  • New agreements to supply GenEco electrolyzers to projects in Europe, the Americas and Asia can shape how quickly Plug Power converts its project pipeline into recognized sales and future cash inflows.
  • Your read on Plug Power is one view; the desks covering it have another. See what analysts think Plug Power's shares could be worth.

The issue now is whether Plug Power's current share price is justified by the level and trajectory of its sales.

Is Plug Power Getting Expensive on Sales?

P/S is usually a cleaner yardstick for Plug Power because losses make earnings-based metrics hard to read. On this measure, the stock trades on a P/S of 3.5x, compared with an Electrical industry average of about 2.1x and a peer group around 1.9x. That means the market is currently paying a higher price for each dollar of Plug Power revenue than for many similar businesses.

Plug Power screens overvalued on this framework, since the current P/S sits well above the level suggested by a tailored fair multiple that factors in its margins, risk profile and scale. The gap is large enough that the model is effectively flagging how heavily recent losses and cash burn weigh on the valuation, rather than pointing to a precise target number. Despite new electrolyzer agreements with Arcadia eFuels and Allied Biofuels broadening the project pipeline, the share price still implies a rich tag on existing sales.
