Bloom Energy Sinks 4% as Negative Cash Flow Overshadows Third Guidance Raise; FuelCell and Plug Power Hold Steady

A record quarter and a third guidance raise this year are clashing with negative cash flow at Bloom Energy (NYSE:BE), and that strain is impacting the price. Bloom Energy stock is down 4% to $208.74 in morning trading. Still, Bloom Energy shares remain up 140% year to date despite the drop.

Meanwhile, FuelCell Energy (NASDAQ:FCEL) stock is unchanged at $11.58, holding steady while shares of its larger fuel cell rival slip. Plug Power (NASDAQ:PLUG) stock is practically unchanged at $1.38, matching the calm in FuelCell stock against the drop in Bloom Energy stock.

The Global X Hydrogen ETF (NASDAQ:HYDR) is unchanged at $36.39, leaving the hydrogen and fuel cell group flat as a whole. Broader trading is softer, with the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) down 0.4% to $761.23, a far smaller dip than the slide in Bloom Energy stock.

Negative Cash Flow Overshadows a Record Quarter

Bloom Energy reported record Q3 2026 results after the previous session’s close, with sales of $1.24 billion topping a $1.07 billion consensus. Deployments for large data center and AI infrastructure customers drove product revenue up 179.4% year over year (we profiled seven suppliers riding the same AI data-center expansion, from power to cooling, in a free report here).

Profit followed suit, as non-GAAP earnings per share (EPS) of $0.94 cleared expectations. Management lifted its full-year outlook for the third time.

The same report showed Bloom Energy’s operating cash flow swinging to negative $27.1 million as inventory, contract assets and receivables climbed. Bloom Energy also poured $153.5 million into production capacity at its Fremont and Newark facilities, pushing its free cash flow to a use of $181 million. Chief financial officer Simon Edwards stated on the earnings call, “The timing of large deliveries and related cash collections will vary from quarter to quarter and those differences even out over time.”

FuelCell and Plug Power Hold Firm as Bloom Energy Slides

Bloom Energy sells solid oxide fuel cell power servers installed on-site for data centers and utilities, recognizing product revenue on delivery while billing follows contract milestones. This structure lets sales run ahead of cash, with the gap sitting in contract assets and receivables until billed and collected. FuelCell earns revenue as its utility-scale fuel cell modules are ordered, built and serviced, while Plug Power’s business is weighted toward hydrogen fuel and handling equipment.

Flat trading in FuelCell and Plug Power shares marks the selling in Bloom Energy stock as specific to its report. Shares of FuelCell remain up 58% year to date; bulls cite its growing data center backlog, while bears note its latest quarter missed on revenue and earnings. Plug Power stock is down 30% on the year; a narrowing gross loss and raised revenue outlook support bulls, though continued losses keep bears cautious.

On expansion, management at Bloom Energy is adding production lines gradually so spending “tracks demand as we see it, rather than running ahead of it,” and the company is expanding its Fremont footprint beyond its current 5 gigawatts of annual manufacturing capacity. The quarter also brought Bloom Energy’s addition to the S&P 500.

Collections Hold the Key for Bloom Energy

A backlog that management says is “continuing to expand faster than our revenue” grounds the bull case for Bloom Energy, along with collections catching up with deliveries. Management now expects full-year revenue of $4.4 billion to $4.6 billion and non-GAAP EPS of $3.10 to $3.40. Edwards calls Bloom Energy a “self-funding business,” with operating results paying for the investments needed to grow.

On the bearish side, inventory and receivables could keep absorbing cash as Bloom Energy scales, and management plans further working capital investment to support growth. According to Edwards, the quarter’s cash use is “not the beginning of a trend,” and Bloom Energy ended the period with $2.5 billion in cash. Bloom Energy’s Q4 2026 report will show whether that catch-up holds, and investors weighing their exposure should adjust their holdings carefully given the uneven timing of cash collections.
