Bloom Energy (NYSE:BE) shares are tumbling 13% to $188 in Friday afternoon trading, dragging Bloom’s peers lower across the hydrogen and fuel-cell complex. FuelCell Energy (NASDAQ:FCEL) stock is off 9% to $21, while Plug Power (NASDAQ:PLUG) shares are slipping 4% to $2.10.
There isn’t a clean, company-specific catalyst behind the Bloom Energy stock move today. It looks like high-beta profit-taking on a broad risk-off session, with a crowded AI-power trade unwinding after powerful rallies in Bloom Energy and FuelCell Energy shares.
The Global X Hydrogen ETF (NYSEARCA:HYDR), which holds all three names, is down 5% to $42. That confirms the pressure is sector-wide rather than idiosyncratic to any one issuer.
Bloom Energy Leads the Drop After a Vertical Run
Bloom Energy stock is still up 119% year to date (YTD) even after Friday’s drop, and that gain is really the point. Vertical rallies invite sharp air pockets when momentum flips, and today has the look of one of those days.
The bull case, which powered the rally, centers on the company’s on-site power deals for AI data centers, including a warrant partnership with Oracle (NYSE:ORCL | ORCL Price Prediction). Bloom Energy’s Q1 2026 report reinforced that story, with revenue of $751.1 million, up 130.4% year over year (YoY), and management raised the company’s full-year guidance to $3.4 billion to $3.8 billion.
The overhang is an early-July short-seller report that questioned Bloom Energy’s supply-chain and production-capacity claims and prompted a securities class-action investigation. Nothing new hit the wire today, but the bears have a ready-made narrative when the market turns defensive.
FuelCell Energy Cools After a Face-Ripping Rally
FuelCell Energy stock is trading at $21.37, off 8% on the session, yet the shares are still up 192% YTD. That 2026-to-date figure is the biggest in the group and explains why the pullback still looks orderly relative to the underlying gain.
FuelCell Energy’s Q2 2026 earnings report was mixed. The company’s revenue came in at $35.6 million, down 5% YoY, and the company took a $42.6 million non-cash impairment tied to its Groton project. The offset is a commercial pipeline management put at 4 gigawatts, with 90% tied to data center proposals.
Plug Power’s Smaller Drop Reflects a Smaller Rally
Plug Power stock is down 4%, the mildest hit of the three. That’s less a sign of relative strength than of a stock that never joined the parabolic move, with Plug Power shares up only 7% YTD.
Plug Power’s Q1 2026 report showed revenue of $163.5 million, up 22.3% YoY, and management is targeting positive EBITDAS in Q4 2026. The company also flagged roughly $275 million in expected proceeds from hydrogen project asset monetization, a key liquidity marker for a story that still runs on cash.
What Investors Can Watch Next
The Global X Hydrogen ETF is a narrow, single-theme fund, and its 30% YTD gain shows exactly how concentration risk can cut both ways. Investors sizing their exposure via HYDR or these single-stock names should consider keeping their position sizes modest given the volatility on display today.
The bull case still rests on AI data center power demand, and Bloom Energy’s Oracle-linked deals remain the clearest evidence that thesis is real. The bear case, sharpened by the July short-seller report, is that valuations already price in a lot of that growth, and any slowdown in adoption could unwind more of the rally.
Investors can watch for whether Friday’s selling persists into next week and whether Bloom Energy stock holds $185. Forward earnings updates from all three companies in the weeks ahead could reset the narrative in either direction.
