Why Is Plug Power Stock Riding High?

Plug Power (NASDAQ: PLUG), a hydrogen fuel cell company, saw its stock jump 20% on September 17, 2025, and up a whopping 40% in just one week. PLUG stock is riding high after the company extended its partnership with the logistics company, Uline, all the way to 2030. On top of that, it has also teamed up with GH2 Global in Brazil to bring hydrogen-powered logistics to the country. With this kind of momentum, you must be thinking: Is this the start of a genuine turnaround for the hydrogen company, or is it a hype-driven rally for a fundamentally troubled business?

To get there, we’ll discuss several key factors in the sections below: the company’s actual growth trajectory, its troubling profitability picture, balance sheet stability, market resilience, and what growth drivers could justify the risk. That being said, if you seek an upside with less volatility than holding an individual stock, consider the High Quality Portfolio. It has comfortably outperformed its benchmark—a combination of the S&P 500, Russell, and S&P MidCap indexes—and has achieved returns exceeding 91% since its inception.

Is Plug Power actually growing?

The numbers tell a mixed story. Plug reported $174 million in Q2 revenue, a 21% increase versus Q2 2024, driven by robust demand for its GenDrive fuel cells, GenFuel hydrogen infrastructure, and GenEco electrolyzer platforms. Electrolyzer revenue tripled year-over-year, reaching $45 million. Over the last three years, the company has grown revenues at an average rate of 7.8% – not bad, but hardly spectacular. But here’s where it gets interesting: while quarterly revenue grew 21.4% recently, the annual picture shows revenues actually declining 1.7% from $684 million to $673 million over the last 12 months.

Does it actually make money?

This is where things get ugly – really ugly. The company is burning cash at levels that would make even the most risk-tolerant investors nervous:

• Operating margin: -134.7% (vs. 18.6% for S&P 500)
• Operating cash flow margin: -89.7% (vs. 20.3% for S&P 500)
• Net income margin: -292.8% (vs. 12.6% for S&P 500)

With a net loss of $2.0 billion over the last four quarters, Plug Power isn’t just unprofitable – it’s going through cash at an alarming rate. That said, the company aims for gross margin neutrality by Q4 2025.

How financially stable is Plug Power?

The balance sheet looks weak across multiple metrics:

• Debt-to-equity ratio: 44.0% (vs. 20.9% for S&P 500)
• Cash-to-assets ratio: 4.2% (vs. 7.0% for S&P 500)
• Total debt: $992 million against a market cap of $2.3 billion

With only $141 million in cash against $3.4 billion in total assets, the company has limited financial cushion. This brings up the equity dilution concern – Plug Power may need to continue issuing new shares to fund operations, which dilutes existing shareholders’ value.

How does PLUG perform during market downturns?

The track record is concerning:

• 2022 Inflation Shock: PLUG fell 95.3% from $73.18 to $3.42 (vs. S&P 500’s 25.4% decline)
• 2020 COVID Pandemic: Dropped 51.7% (vs. S&P 500’s 33.9% decline)
• 2008 Financial Crisis: Plummeted 84.8% (vs. S&P 500’s 56.8% decline)

The pattern is clear: during market stress, PLUG gets hit much harder than the broader market. Currently trading around $2.00, it’s still miles away from its 2021 high of $73.

The Growth Drivers: What Could Go Right?

Despite the financial challenges, there are legitimate reasons for optimism:

The electrolyzer segment emerges as Plug’s most promising growth driver, with revenue tripling year-over-year to $45 million amid accelerating global hydrogen infrastructure deployments. Plug Power extended its contract with logistics firm Uline through 2030 and formed a partnership with Brazil-based GH2 Global to deploy hydrogen-powered logistics infrastructure. This expansion is expected to increase Plug’s hydrogen nameplate network capacity to over 40 tons per day (TPD), supporting continued growth in hydrogen sales and margin expansion through 2025.

Is PLUG overvalued after the recent rally?

Surprisingly, no. With a price-to-sales ratio of 3.3 versus 3.2 for the S&P 500, PLUG is actually trading in line with the broader market. Given the growth potential in the hydrogen economy, this could be considered reasonable – if the company can execute.

The Bottom Line: Risk vs. Reward

The key question is: Should you invest in Plug Power?

This is a classic high-risk, high-reward situation. Here’s the reality:

• The Bull Case: The hydrogen economy is real and growing. Plug Power has leading technology, expanding partnerships, and a reasonable valuation. If they can achieve profitability, the stock could multiply several times over.
• The Bear Case: The financial metrics are genuinely scary. Massive losses, cash burn, and equity dilution risk make this extremely risky.
• The Verdict: Only invest money if you can afford to lose a significant portion of your wealth – as high as 80% to 90% – as we have seen in the past with PLUG stock. If you believe in the hydrogen economy’s long-term potential and can stomach extreme volatility, PLUG might deserve a small position in a diversified portfolio. Overall, it’s a speculative bet on a transformative technology with an execution-challenged company.

You could explore the Trefis Reinforced Value (RV) Portfolio, which has outperformed its all-cap stocks benchmark (combination of the S&P 500, S&P mid-cap, and Russell 2000 benchmark indices) to produce strong returns for investors. Why is that? The quarterly rebalanced mix of large-, mid- and small-cap RV Portfolio stocks provided a responsive way to make the most of upbeat market conditions while limiting losses when markets head south, as detailed in RV Portfolio performance metrics.

The recent 40% weekly gain shows the upside potential, but the 95% crash in 2022 shows the downside risk. Choose accordingly.
