Shares of Bloom Energy tumbled 6.5% to $223.91 on Wednesday, extending a bruising slide from a 52-week high of $351.28 as profit-taking collided with unresolved questions about the fuel-cell maker's most critical raw material. For shareholders who rode a ~950% one-year rally, the selloff is a stress test of whether Bloom's transformation from clean-energy also-ran to AI-power darling can withstand real scrutiny.
• A Short Seller's Supply-Chain Math Problem Refuses to Go Away
The controversy began July 8, when Hunterbrook Capital published a report titled "Bloom's Big Lie," accusing the company of downplaying its reliance on Chinese suppliers for scandium oxide — a rare-earth element essential to its fuel cells. The report argues that Bloom's 5-gigawatt production target would require roughly 220 tons of scandium oxide per year — nearly the entire projected global supply of about 240 tons. Bloom filed an 8-K with the SEC calling the claims "false and misleading," but its statement that its supply chain can support 25 GW of annual production "is not reconcilable with publicly visible operating supply." Until the company discloses hard sourcing data, the overhang lingers.
• The Valuation Already Prices In Perfection
Bloom trades at 514 times trailing earnings and 184 times forward earnings.
The company raised 2026 revenue guidance to $3.4–$3.8 billion, with non-GAAP EPS guided at $1.85–$2.25. That guidance is ambitious: to hit the $3.6 billion midpoint, Bloom needs roughly $950 million in average quarterly revenue from Q2 to Q4. Any stumble on the July 28 earnings report could be punishing at these levels.
• Insiders Have Been Cashing Out
Insiders sold $59.8 million in the last three months.
No insiders bought shares in the past year. While many sales were pre-planned for tax purposes, the one-directional pattern adds to investor unease during a volatile stretch.
• Big AI Deals Anchor the Bull Case — For Now
Bloom and Brookfield expanded their AI power financing framework from $5 billion to $25 billion , and the company has an Oracle agreement for up to 2.8 gigawatts of fuel-cell capacity.
Bloom reports Q2 results on July 28, and analysts expect EPS of $0.23 — a number that must prove the backlog is converting into real revenue. Baird holds a $310 target; UBS raised to $350. Wall Street still believes, but the stock now needs delivery, not promises.
