In a week shortened by the Independence Day holiday, Plug Power (NASDAQ:PLUG) managed a modest 3.9% advance, adding just $0.10 to close at $2.64. The stock's movement was more about churn than direction, with 209.2 million shares changing hands over four sessions—roughly 62% of the latest short interest figure.
Short interest stood at 339.6 million shares as of June 15, representing 24.68% of the float and requiring 5.8 days to cover. The value of those short positions, approximately $950.9 million, far exceeds Plug's unrestricted cash of $223 million reported at the end of the first quarter. This cash position remains a central concern for investors, even as the company touts progress on its Denmark power-to-X project.
Plug delivered a 5 MW GenEco PEM electrolyzer system to European Energy's Måde Power-to-X site in Denmark, calling it a benchmark installation. The company says the plant can produce about 550 metric tons of green hydrogen annually. However, the 5 MW installation represents only about 1.6% of Plug's total global electrolyzer capacity of over 320 MW, raising questions about scalability.
CEO José Luis Crespo stated that the company is shifting from single deployments to a more repeatable model. Rene Alcaraz Frederiksen, who leads Power-to-X at European Energy, confirmed the companies have completed installation and commissioning and have achieved certified green hydrogen output. Yet for shareholders, the key question remains whether Plug can replicate these installations at a larger scale.
The broader hydrogen fuel-cell sector showed mixed results. Bloom Energy (NYSE:BE) gained 7.5% for the week, buoyed by the AI data-center angle after Bloom and Brookfield expanded their infrastructure power deal to $25 billion. FuelCell Energy (NASDAQ:FCEL) surged 17.1%, boosted by a $49 million financing from the Export-Import Bank and a B. Riley upgrade to buy with a $32 price target. In contrast, Ballard Power Systems (NASDAQ:BLDP) fell 2.8%, while the iShares Global Clean Energy ETF (NASDAQ:ICLN) eked out a 0.9% gain.
Plug's first-quarter results showed revenue climbing 22% year-over-year to $163.5 million, while GAAP gross margin improved to negative 13% from negative 55% a year earlier. Adjusted EPS loss narrowed to $0.08 from $0.17. Crespo said the quarter "positions us to achieve our EBITDAS positive target in Q4 2026." Total cash stood at more than $802 million, but restricted cash accounts for a significant portion, leaving only $223 million in unrestricted cash—a key metric for investors.
Technically, the stock faces resistance at $2.82, last week's high, while a close below $2.54 would erase the holiday week's gain. With no earnings date yet announced, MarketBeat projects the Q2 report around August 10, with a consensus loss of $0.10 per share. The coming weeks will likely be driven by cash concerns and the company's ability to demonstrate repeatability in its project pipeline, which exceeds $8 billion.
