Stock Analysis

Is Plug Power A Bargain After Green Hydrogen Expansion And Prolonged Share Price Slump?

  • Wondering if Plug Power at around $2.32 is a bargain or a value trap? You are not alone, and this is exactly the question we are going to tackle head on.
  • Over the last week the stock is up about 5.5%, roughly 3.3% over the past month, but returns are still slightly negative year to date and deeply underwater over 3 and 5 years, down 83.5% and 92.7% respectively.
  • Those swings have come alongside ongoing headlines about Plug Power's push to scale its green hydrogen ecosystem, including new project announcements and partnerships aimed at building out production and fueling infrastructure. At the same time, coverage has focused on funding needs, dilution risk, and policy support for clean energy. All of these factors shape how investors are repricing the stock's long term potential and risk.
  • Right now Plug Power scores just 2/6 on our valuation checks. We will walk through what different valuation methods say about that low score, and then finish by looking at a more complete way to think about what the market might really be missing.

Plug Power scores just 2/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: Plug Power Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a business is worth today by projecting its future cash flows and discounting them back into current $ terms. For Plug Power, the latest twelve months Free Cash Flow is deeply negative at about $904 million, reflecting heavy investment and operating losses as the hydrogen platform scales.

Analysts expect cash flows to remain negative for several years before turning positive, with projections moving from roughly $368 million outflow in 2026 to $257 million of positive Free Cash Flow by 2029. Beyond the analyst window, Simply Wall St extrapolates this improvement, with modeled FCF rising to around $1.34 billion by 2035 as the business matures.

When all these future cash flows are discounted back, the DCF model arrives at an intrinsic value of about $7.30 per share. Compared with the current price near $2.32, this implies the stock is trading at roughly a 68.2% discount, which indicates the market is heavily discounting Plug Power’s ability to execute on these growth plans.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Plug Power is undervalued by 68.2%. Track this in your watchlist or portfolio, or discover 908 more undervalued stocks based on cash flows.

Approach 2: Plug Power Price vs Sales

For companies that are not yet consistently profitable, the price to sales ratio is often more useful than earnings based metrics, because it compares what investors are paying to the revenue the business is already generating rather than volatile or negative earnings.

In general, higher growth and lower risk justify a higher multiple, while slower growth, thin margins and execution risk should pull a normal valuation multiple down. For Plug Power, the stock currently trades on a price to sales ratio of about 4.71x. That is higher than both the Electrical industry average of roughly 2.17x and the peer group average of around 3.46x. This suggests the market is already pricing in stronger growth or a strategic premium.

Simply Wall St’s Fair Ratio framework goes a step further by estimating the multiple Plug Power should trade on, given its growth outlook, risk profile, margins, industry and market cap. For Plug, this Fair Ratio is about 0.17x, which is far below the current 4.71x. On this basis, even allowing for uncertainty in the inputs, the shares look richly valued relative to what the fundamentals currently justify.

Upgrade Your Decision Making: Choose your Plug Power Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, a simple tool on Simply Wall St’s Community page that lets you attach a story to your numbers by linking your view of Plug Power’s future revenue, earnings and margins to a concrete forecast and fair value. It then automatically compares that fair value to today’s price to help guide investment decisions, updating dynamically as new news or earnings are released. This makes it easy to see, for example, how one investor might build a bullish Plug Power Narrative that supports a fair value closer to the top analyst target of $5.00, while another, more cautious investor uses the same framework and information to justify a fair value near the most bearish $0.55.
