Should You Buy Plug Power Stock While It's Below $3?

Since its founding, Plug Power (NASDAQ: PLUG) has never turned an annual operating profit. The company has been looking to build a vertically integrated green hydrogen ecosystem, but it has faced persistent negative margins and high cash burn.

Although it has consistently lost money, the company is looking to execute a turnaround for the ages. Investors got a glimpse of its progress in its recent earnings results, and management expects further improvements by the end of this year. With the stock trading below $3 per share, is now the perfect time to buy?

Project Quantum Leap is yielding early results for Plug Power

Plug Power's fourth-quarter 2025 earnings results gave investors reason for optimism. In the quarter, the hydrogen company reported revenue of $225 million and an adjusted per-share loss of $0.06, both of which exceeded analysts' expectations. More importantly, the company achieved a positive gross profit of $5.5 million, translating into a 2.4% gross margin. This was a massive improvement from the fourth quarter last year, when it had a gross margin of negative 122%.

Its gross margin improvement was driven by "Project Quantum Leap," the company's initiative to improve margins and cash flow by optimizing its operations. Last year, it launched a restructuring plan that included strategic workforce reductions and price increases across certain product offerings. It has also reprioritized certain hydrogen infrastructure and new product investments.

In addition, it reduced hydrogen production costs and enhanced its fuel network by leveraging its vertically integrated hydrogen platform, scaling up its internally owned plants in Georgia, Tennessee, and Louisiana. Together, these three plants can produce up to 40 tons of liquid hydrogen per day and help the company eliminate the need for middleman providers,, which has contributed to its high cash burn.

Management estimates that Project Quantum Leap could generate between $150 million and $200 million in annual cost savings and is optimistic that the company can achieve positive earnings before interest, taxes, depreciation, and amortization -- or EBITDA -- by the fourth quarter of this year.

Plug Power has made other strategic moves recently

Another positive development for investors was Plug Power's revised licensing agreement with Walmart. Under the new agreement, Plug Power agreed to grant Walmart a "contingent, limited-use license to access and use certain escrowed GenKey System-related materials." In return, Walmart agreed to forfeit its vested warrants and cancel its remaining unvested portions, eliminating potential future share dilution of over 42 million shares of Plug Power stock.

Later this year, Plug Power will seek to offer up to 250 megawatts of hydrogen electricity in an upcoming emergency power grid auction. This is the auction pushed by the Trump administration to supply the PJM Interconnection region, which faces power shortages due to surging electricity consumption from AI data centers.

Plug Power's turnaround is underway

Plug Power has never turned an annual profit, a fact investors must grapple with. However, Project Quantum Leap has gotten off to a good start, and a path to profitability is becoming more possible as indicated by the company's recent quarterly results. If you are confident that its turnaround efforts will bear fruit, the stock could be a good buy. As for me, I'd like to see evidence of further progress in the coming quarters before investing in the stock.
