Plug Power stock (ISIN US72919P2020) fell 3.32 percent to USD 2.04 on Nasdaq on September 23, 2026. The move followed a filing that said Chief Operating Officer Dean C. Fullerton will resign effective October 23, 2026, to join another company.
COO departure sets a date
According to StockTitan, Fullerton will help transfer his duties to executive vice presidents and vice presidents before his departure. The filing also states that the resignation was not caused by a disagreement over Plug Power operations, policies or practices.
The timing gives the management change a defined checkpoint. For investors, the key issue is execution during the handover because Plug Power is still funding an expansion across hydrogen production, storage, delivery and fuel cell systems.
Q2 loss narrows year over year
Plug Power posted a Q2 2026 GAAP net loss of USD 188.2 million, compared with USD 227.1 million in Q2 2025, according to StockTitan. The USD 38.9 million improvement shows a narrower loss, but the company remained unprofitable in the latest quarter.
Plug Power revenue reached USD 178.299 million in Q2 2026, up from USD 163.513 million in Q1 2026. Operating loss also narrowed from USD 109.489 million in Q1 to USD 64.108 million in Q2, while cash from operating activities remained negative at USD 94.064 million in Q2.
Electrolyzer delivery adds operating proof
On September 22, 2026, Plug Power announced the shipment of a 1 MW GenEco PEM electrolyzer to HWR Hydrogen in Invercargill, New Zealand, as reported in the company release carried by Finanznachrichten. The equipment is intended to produce hydrogen for HWR's dual-fuel hydrogen-diesel heavy truck fleet.
The delivery gives the stock a concrete operating data point beside the management transition. Plug Power's investor relations page says the company has deployed more than 74,000 fuel cell systems and more than 280 fueling stations, while its latest quarterly results are for Q2 2026.
Stock stays below yearly high
At USD 2.04 on September 23, 2026, Plug Power stock stood 55.46 percent below its 52-week high of USD 4.58 and 20.00 percent above its 52-week low of USD 1.70. Market capitalization was USD 2,845,942,800 on the same date, making the loss trend and cash use central measures for the next company update.
