Fuel Cell Stocks Rally as Post-Earnings Selloff Keeps Unwinding: Bloom Energy Jumps 6%, FuelCell Climbs 5%, Plug Power Gains 3%

Fuel cell stocks are climbing together as the selloff that followed Bloom Energy‘s (NYSE:BE) Q3 2026 report continues to reverse, a sign that last week’s cash flow scare is losing its grip on the group. Bloom Energy stock is at $215.26, up 6% as the session unfolds, a gain that pushes its recovery from the post-earnings slide another step forward.

At the same time, FuelCell Energy (NASDAQ:FCEL) stock is at $12.02, up 5%, landing just behind the group leader and confirming that the bounce reaches past a single name. Plug Power (NASDAQ:PLUG) stock is at $1.41, up 3%, posting the smallest advance of the three while still moving in the same direction.

A dedicated sector fund is rising with them, as the Global X Hydrogen ETF (NASDAQ:HYDR) is up 3%. For broader reference, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is up 0.3%, leaving the fuel cell corner far outpacing the overall market. That lift comes ahead of the Federal Reserve’s rate decision due later this week.

Q3 Beat, Cash Flow Worries

Bloom Energy’s Q3 report last week delivered adjusted earnings of $0.94 per share against a $0.67 estimate.

Revenue of $1.24 billion topped the $1.07 billion forecast, and the company raised its annual revenue outlook for the third time this year.

Still, Bloom Energy’s operations used $27 million in cash as more money was tied up in inventory and in amounts customers hadn’t yet paid, though the chief financial officer stated, “That’s not the beginning of a trend.” In the first trading reaction, Bloom Energy shares fell 11% on worries about cash flow and near-term margins before bouncing.

Bloom Energy Leads While FuelCell and Plug Power Ride Different Models

Bloom Energy sells on-site power platforms and has been the largest beneficiary of data center electricity demand in the fuel cell group (we rounded up seven suppliers powering the AI data-center expansion, from power to cooling, in a free report here). Its product revenue rose 179.4% year over year to $1.07 billion in Q3, and non-GAAP gross margin expanded to 34.5%.

FuelCell builds utility-scale fuel cell platforms and earns revenue as modules are ordered, built and serviced, a model aimed at large stationary loads. Bulls cite its growing data center pipeline, while bears point to a recent quarterly miss.

Plug Power is weighted toward hydrogen fuel and handling equipment, a separate market from stationary power for computing loads. If data center enthusiasm keeps concentrating in stationary power names, Plug Power stock may lag the leaders.

Global X’s hydrogen fund held Bloom Energy at 15.5% of net assets as of May 31, with Plug Power at 10.8% and FuelCell at 7.2%. Those weights help explain why the ETF is tracking its biggest U.S. holdings higher.

Bloom Energy’s Rebound Runs Into Its Cash Flow Question

Bloom Energy’s optimistic outlook hinges on data center power demand keeping its revenue outlook rising, and the company now guides for $4.4 billion to $4.6 billion in full-year 2026 sales. Management’s commentary supports that view, with founder and CEO KR Sridhar stating on the October 22 call that the backlog is “continuing to expand faster than our revenue.”

A bear case holds that the company’s cash flow falls behind its revenue growth, leaving Bloom Energy shares exposed to another sharp swing. Free cash flow at Bloom Energy was a use of $181 million in Q3, even though it stood at a positive $42 million year to date.

Bloom Energy still needs to show whether its operations bring in cash next quarter. Anyone holding BE stock should consider adjusting their positions carefully given how sharply the shares moved after the report.
