Published on 09/10/2026 at 14:07 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Plug Power Inc. stock (ISIN US72919P2020) closed at USD 2.17 on the Nasdaq on September 9, 2026, marking a 3.9 percent decline from the prior session and leaving the shares near the lower end of their recent trading range. As an overview on September 10, 2026 noted, this move came against a broader risk-off backdrop in U.S. equities, with investors reassessing higher-risk growth names such as hydrogen and fuel-cell plays.
Short sellers target Plug Power amid turnaround efforts
According to Invezz on September 9, 2026, Plug Power stock was trading at USD 2.26 during the session, implying a market capitalization of roughly USD 3,000,000,000 and reflecting a drop of about 47 percent from a high of USD 4.31 reached in June this year. The same analysis highlighted that short interest in Plug Power has climbed to about 20 percent of the free float, with data from Benzinga and Seeking Alpha cited as evidence that bearish investors are increasing their exposure despite management’s turnaround plans.
Invezz also pointed to Plug Power’s rising share count as a key concern for short sellers, noting that outstanding shares have increased from about 577,000,000 in 2022 to roughly 1,120,000,000 in the prior year and to around 1,390,000,000 more recently. For investors, that acceleration in issuance reinforces worries about dilution even as the company works to improve profitability and cash flow.
Latest quarterly figures show modest growth and narrowing loss
Plug Power’s most recent earnings report covers the second quarter of 2026 and offers a mixed but improving picture of its operations. As summarized by Invezz, Plug Power generated revenue of USD 178,000,000 in the second quarter of 2026, up from USD 173,000,000 in the same period of the prior year, which corresponds to an increase of around 2.9 percent year over year. Over the first six months of 2026, revenue rose to USD 341,000,000 compared with USD 307,000,000 in the first half of the previous year, a gain of roughly 11.1 percent that indicates continued demand from large logistics and retail customers.
The segment breakdown in the same overview underscores where growth is strongest. Services performed on fuel cells brought in USD 29,800,000 in the second quarter of 2026, almost doubling from USD 16,300,000 a year earlier and lifting first-half revenue in that division to more than USD 51,000,000. Plug Power’s power purchase agreements contributed more than USD 26,000,000 in the first six months of 2026, while fuel delivered to customers generated over USD 39,000,000 in revenue. In contrast, equipment sales declined significantly, falling to USD 81,800,000 in the second quarter as large one-off projects became less prominent in the short term.
On the bottom line, Plug Power’s net loss in the second quarter of 2026 narrowed to about USD 190,000,000, primarily due to changes in the fair value of convertible debt instruments, according to Invezz. The company also recorded more than USD 16,000,000 in interest expenses during the quarter, underscoring the cost of its capital structure as it invests in green hydrogen production and fuel-cell infrastructure.
Guidance and growth expectations underpin long-term thesis
While the near-term share-price performance has been weak, analyst expectations still assume meaningful top-line growth for Plug Power over the coming years. The same analysis on Invezz reported that consensus forecasts call for Plug Power’s annual revenue to grow by about 15.3 percent to approximately USD 819,000,000 in 2026, followed by a further increase to around USD 968,000,000 in 2027. These projections imply that the company’s current run-rate, with USD 341,000,000 in revenue already booked in the first half of 2026, will need to accelerate in the second half to meet full-year expectations.
For investors, the key question is whether that growth can outpace ongoing dilution and losses. The modest year-over-year revenue increase of about 2.9 percent in the second quarter of 2026 contrasts with the much faster expansion in the share count highlighted by Invezz. That imbalance is one reason short sellers remain active, even as management targets a path to positive adjusted EBITDA, and it continues to shape sentiment toward Plug Power stock.
Technical picture: bearish flag below key moving average
From a chart perspective, Plug Power’s recent trading behavior points to lingering downside risk. The daily chart referenced by Invezz shows the shares moving within an ascending channel that forms part of a bearish flag pattern, a formation that often precedes a renewed decline. The stock has remained below its 50-day moving average, and the Percentage Price Oscillator has slipped under the neutral level, reinforcing the view that momentum currently favors the bears rather than the bulls.
Based on this setup, the same technical commentary argued that Plug Power stock could retest a key support level around USD 1.87, with a potential move below that threshold opening the way to further losses toward approximately USD 1.50. For holders of Plug Power stock, those levels serve as important reference points for assessing how much technical damage has already been done and where a stabilization or reversal would need to occur to change the medium-term trend.
Stock trades near the bottom of its 52-week range
A recent overview of Plug Power’s performance on September 9, 2026 noted that the shares finished that session at USD 2.17 on the Nasdaq, within an intraday range of roughly USD 2.16 to USD 2.30 and close to the lower end of a 52-week span between USD 1.41 and USD 4.58. That same snapshot, which cited data from The Motley Fool, underscores how far Plug Power stock has retreated from its highs over the past year and why sentiment remains fragile among retail investors and institutional traders alike.
In broader market terms, Plug Power stock also underperformed the large-cap benchmark on September 9, 2026. According to an index wrap referenced by the same overview, the S&P 500 declined by about 0.6 percent on that day, meaning Plug Power’s 3.9 percent drop left it trailing the benchmark by more than three percentage points. Against that backdrop, the hydrogen specialist’s combination of elevated short interest, ongoing losses and a technically weak chart continues to dominate the narrative around Plug Power stock as trading on September 10, 2026 gets under way.
