Biggest thing to watch: the price is not yet in a clear uptrend, so timing is the risk more than the business. ## What is the Plug Power share price today? Plug Power Inc.'s share price was $1.46 at the close on 4 November 2026. It has been moving sideways for 18 weeks. That is 38.7% below its average price over the last 200 trading days. In the last 52 weeks it traded between $1 and $4, and at that close it sat 4% of the way up from that low. Over the past 13 weeks it has done worse than the S&P 500, and it has been behind for 19 weeks running. Over the last 10 years the share price moved −16% while the S&P 500 moved +261%, so it is behind the index over that whole period. It was last ahead over 13 weeks in the week of 26 June 2026. The chart above shows the 13-week comparison for every week. This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row. ## What dividend does Plug Power pay? Plug Power Inc. pays no dividend. In the last 12 reported quarters it declared no dividend per share, so there is no payout history to chart and no yield to show. Companies like this usually keep their earnings in the business, so the cash-flow sections show where that cash goes. ## Which stock lists is Plug Power on? Plug Power is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list. ## Is Plug Power profitable? Plug Power Inc. posted a net loss of $188 M in the Jun 2026 quarter. That quarter includes a one-off gain bigger than its revenue, so the comparison with last year does not reflect normal business. The full FY25 year was a loss of $1.6 B. That loss is 105.6% of the quarter's revenue. The same quarter a year earlier lost $227 M. 12 of the last 12 reported quarters were loss-making. Read this profit with care: at −$188 M it is bigger than the quarter's whole revenue of $178 M. No business earns more than it takes in from sales, so this is a one-off item (for example a debt settlement, a tax write-back or an asset sale), not money the business earned. The underlying business is running at a −24.9% operating margin. The jump on last year, and any P/E built on this profit, come from the one-off, not from a real turn in earnings. ## How much revenue does Plug Power make, and is it growing? Plug Power Inc. reported $178 M of revenue in the Jun 2026 quarter, +2.5% on the same quarter a year earlier. That is the 6th quarter in a row with growth on the year before. Over 4 years it has grown 9.0% a year on average. The last full year, FY25, came in at $710 M. The last four reported quarters add to $744 M. FY25 revenue was $710 M, +12.9% on the year before. Recent pace: the last four quarters grew +11.1% on average, against 9.0% a year over the longer run, so this year is growing faster than its own long-run rate. Is growth speeding up? Revenue over the last 12 months grew +10.6%, against +4.3% a year over the last 8 quarters (accelerating). ## How much of every $100 of sales does Plug Power keep? Plug Power Inc.'s operating margin was −24.9% in the Jun 2026 quarter, 63.4 percentage points higher than the same quarter a year ago. Across 5 years it has been between −177.6% and −82.8%. The latest quarter is above every full year in that period. Why the margin moved: operating margin changed +63.4 percentage points on the year while gross margin changed +27.3 points. So the gain came mostly from costs below the gross margin, such as staff and overheads, measured against sales. ## Is Plug Power's profit turning into cash? Plug Power Inc.'s cash-flow history is too short to judge how much of its profit turns into cash. In FY25 its operations used $536 M of cash, against −$1.6 B of profit. After $126 M of spending on assets, free cash was −$661 M: it spent more than its operations brought in. Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year. What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building. ## Where does Plug Power's cash go? Plug Power Inc. does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent $1.2 B on assets over the last 3 years. Averaged over those years that is 54.3% of FY25 revenue a year. Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn. Spending on assets: $1.2 B over the last 3 years. In short: most of the cash goes on covering the loss, not on new assets; spending on assets is small next to it. ## What is Plug Power's P/E ratio, and how does it compare with its own history? Plug Power Inc. has no P/E right now, because its earnings are negative. The revenue and margin sections are where a turn would show first. Measured against sales instead, the market values Plug Power Inc. at 2.9× its FY25 revenue of $710 M. The P/E comes back here once profit turns positive. ## Is the Plug Power business getting better or worse? Plug Power Inc.'s business trend cannot be read yet. There are fewer than eight usable quarters of growth figures, so there is not enough history to read the trend. This is based on 12 quarters of 2 measures, with some gaps. Why it matters: with too little history, we say so rather than guess a direction. The latest quarter’s profit includes a one-off item bigger than the normal business, so the profit line is shown but does not count in this reading. The return figures here are yearly, not quarterly. They show level and direction only; they can support the growth lines but never decide the reading alone. There are fewer than eight usable quarters, so this page does not guess a direction from so little history. ## How much does Plug Power earn on its capital? Plug Power Inc. earned a ROE of −163% in FY25. Its return on capital used (ROIC) is 28.5 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses. It comes from a −229.8% net margin and 0.27× asset turnover (sales divided by assets). Why the return is what it is (FY25): a −229.8% net margin × 0.27× asset turnover × 2.59× leverage (assets divided by equity) ≈ −160.7% on equity. The margin does its share; borrowing is a big part of it. The key test, return on capital used minus the cost of capital: −15.5% − 13.0% = −28.5 percentage points. The 13.0% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. Negative: growth at these returns loses value until returns improve. ## Does Plug Power have too much debt? Plug Power Inc. has total debt of $1.0 B against shareholder equity of $587 M as of Jun 2026, so its debt is 1.77× its equity. Year by year, that ratio went from 0.18 in FY21 to 0.99 in FY25. Keep that borrowing in mind when reading the returns on this page. ## What is the Plug Power shareholding pattern? 21.9% of Plug Power Inc.'s tradable shares are in short positions, which are bets that the price will fall, so a large group of traders is betting against it. At normal trading volumes, closing those positions would take about 5.9 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead. It is a single reading at one point in time; we do not have its history. Why it is at this level: the figure does not say who holds the short positions or why, so we show the level without guessing the story. ## How far is Plug Power from balance-sheet trouble? For Plug Power Inc., the Z-score is −4.47. A Z-score above about 3 is safe and below about 1.8 signals danger, so this is in the danger zone. It estimates how far the balance sheet is from trouble; it is not a forecast of failure. Why it matters: a Z-score of −4.47 is inside the danger zone, so the balance sheet is a real risk. ## How does Plug Power rank in its industry? 41.4 out of 100, rank 18 of 30 in Electrical Equipment & Parts, with 61% of the evidence available. Plug Power Inc. scores 41.4 out of 100 against the 30 companies it is compared with in Electrical Equipment & Parts, ranking 18. The evidence is balanced: no factor stands out, so another reported quarter is needed before the picture is clearer. The four parts add up to the total exactly: 21.6 + 5 + 10 + 4.8 = 41.4. This is the same number shown on the industry page; it is worked out once for the whole group and read here. What would change it: The score would fall if profit growth turns negative or margins stop improving while the share price lags its sector. ## Which companies is Plug Power compared with? Plug Power ranks 18 of 30 Electrical Equipment & Parts companies on the 4-Factor Sector Score, with 41.4 out of 100. 1.

Missing figures are not scored as bad. They lower the confidence and pull the final score toward the middle. Relative strength counts only when the company has a reading for this week; with no reading, that factor is left out and its 20 points are shared across the other three in proportion. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step path the industry is placed on (basing, turning, breaking out, leader, fading, asleep), read from how many weeks running it has led S&P 500 and whether that lead is growing or shrinking. It describes where the share price stands, not the direction of earnings, and it is not a recommendation; it is left blank for a company whose weekly history is too short or too stale to read. The figures in this ranking come from the industry comparison: results through the Sep 2026 quarter, and the P/E at that quarter's end. The sections above use the latest weekly price, so a P/E or return there can differ a little from the one here. The stage words in this ranking (such as losing its lead or breaking out) describe the lead over the index, not the price phase in the price section.

Nobody can reliably say which way a price will move, and this site does not try (as of 4 November 2026). ### Where is Plug Power in its business cycle? Plug Power Inc.'s FY25 operating margin was −101.4%, against a 5-year range of −177.6% to −82.8%: the middle of its own range, neither a peak nor a low. The latest quarter was −24.9%. Comparing margins with a company's own long history is a good way to see where it is in its cycle (as of 4 November 2026). ### What could break the Plug Power story? Biggest thing to watch: the price is not yet in a clear uptrend, so timing is the risk more than the business. On price, this page treats a rise as over when the share price closes below its 200-day average on two Fridays in a row (as of 4 November 2026). ### Is Plug Power a stock worth studying right now?
