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

The Discounted Cash Flow (DCF) model estimates what a business is worth today by projecting future cash flows and discounting them back to the present. This approach aims to capture the company's potential for value creation over time by using what analysts expect Plug Power to generate in the years ahead.

For Plug Power, the most recent reported free cash flow (FCF) stands at a negative $904 million, signaling cash outflows as the business invests for growth. Projections indicate continued negative cash flows in the next few years. However, analysts estimate the company could turn positive, with FCF projected to rise to $257 million by 2029. These forecasts are based on a combination of analyst consensus for the first five years and extrapolations beyond that period.

Using the DCF method, the model arrives at an intrinsic fair value of $7.05 per share. With the current share price sitting noticeably lower, this suggests Plug Power may be trading at a substantial 71.9% discount to its estimated fair value. This wide margin indicates the stock could be significantly undervalued based on long-term cash flow potential.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Plug Power is undervalued by 71.9%. Track this in your watchlist or portfolio, or discover 932 more undervalued stocks based on cash flows.

Approach 2: Plug Power Price vs Sales (P/S)

For companies that are not yet profitable, like Plug Power, the Price-to-Sales (P/S) multiple is often a more suitable way to gauge valuation. This metric looks at how much investors are willing to pay for each dollar of revenue. It can be especially useful for high-growth or early-stage firms where earnings might not yet reflect their full potential.

The "normal" or fair P/S ratio for a stock can vary widely based on expectations for future growth and the risks the company faces. Companies expected to outpace their peers may warrant a higher P/S, while elevated risk or lower margins could push it lower.

Currently, Plug Power trades at a P/S ratio of 4.0x, which is higher than both the average for its Electrical industry peers (3.26x) and the broader industry average (1.94x). At first glance, this premium pricing might seem concerning to value investors.

This is where Simply Wall St's Fair Ratio comes into play. The Fair Ratio, calculated specifically for Plug Power, stands at 0.15x. Unlike a simple peer comparison, the Fair Ratio incorporates the company’s actual and forecast growth, profit margins, risk factors, industry norms, and market capitalization. This makes it a more tailored benchmark for assessing true valuation.

Comparing the Fair Ratio of 0.15x to Plug Power's current 4.0x P/S reveals that the stock is trading substantially above what would be expected given all these factors. This suggests the company may be significantly overvalued by this measure.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Plug Power Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let’s introduce you to Narratives. A Narrative is a straightforward approach for investors to connect the story they believe about a company, such as Plug Power’s future prospects, risks, and catalysts, to a set of financial outcomes like forecasts of revenue growth, profit margins, and ultimately an estimated fair value.

Narratives uniquely tie your view of the company’s journey to a dynamic financial forecast, making the reasoning behind a fair value both transparent and personal. On Simply Wall St’s Community page, millions of investors use Narratives to not only share their perspectives but also to easily visualize how changing assumptions can impact whether a stock is undervalued or overvalued compared to the current price.

What sets Narratives apart is that they update automatically when new information, such as news announcements or earnings results, comes in, ensuring that your investment thesis always reflects the latest data.

For Plug Power, this means that one investor might build a bullish Narrative around improving policy support and margin expansion (pointing to a $5.00 price target), while another might focus on recurring losses and competition (with a fair value closer to $0.55). Both views can be tested instantly to gauge whether now is the right time to buy or sell.
