Bloom Energy stock tumbled 37% ahead of Q2 earnings, as investor concerns over fuel cell demand and data center power contracts weighed on valuations.
Bloom Energy reported second-quarter earnings after market close on July 28, with shares trading at $158.65, well below the $286.20 average analyst price target. The stock has experienced significant pressure, declining 16% on the day and 37% over the past month, setting the stage for what investors are treating as a pivotal moment for the company's artificial intelligence power thesis.
The central question facing investors is whether Bloom can maintain its stated full-year revenue path of $3.4 billion to $3.8 billion while also demonstrating the sustainable profitability required to justify its 82x forward earnings valuation. A critical vulnerability lies in the company's customer concentration: Brookfield-related product sales exploded from $3 million to $373 million in a single year, making any pipeline softening an existential threat to Bloom's growth story. Investors will also scrutinize execution on Oracle's Project Jupiter—a 2.45 gigawatt deployment—and whether Bloom can diversify its roughly $20 billion backlog beyond Brookfield-dependent business.
In Q2, Bloom delivered results that initially supported the bull case. Revenue surged 166% year-over-year to $1.065 billion, marking the company's first quarter above $1 billion. Product revenue climbed 215% to $935.4 million. The quarter offered more than headline growth: non-GAAP gross margin expanded 604 basis points to 34.3%, and operating cash flow swung positive to $226.4 million from negative in the prior year. Adjusted EBITDA reached $253.4 million, more than six times the prior-year result. These figures provided evidence that Bloom's AI data-center opportunity can produce expanding profitability alongside explosive revenue growth.
CEO KR Sridhar emphasized that all major U.S. hyperscalers and more than a dozen neoclouds, AI laboratories, and colocation data-center operators have now validated and approved Bloom's power solutions for their AI factories. The company is positioning its fuel-cell systems as a proven alternative to traditional combustion technologies at a time when data-center developers need power faster than the electrical grid can provide it.
Perhaps most importantly for the stock, Bloom raised its full-year 2026 guidance to $3.9 billion to $4.2 billion, up from the previous range of $3.4 billion to $3.8 billion. The new midpoint of $4.05 billion implies roughly 100% year-over-year growth. Management also guided for approximately 34% non-GAAP gross margin, $800 million to $900 million in non-GAAP operating income, and adjusted earnings per share of $2.55 to $2.85.
A guidance raise could revive the bull thesis; anything less would likely deepen the drawdown from recent highs. At current valuations, the market is pricing Bloom as the default on-site power provider for AI data centers—a bet that hinges on broader customer diversification and management's ability to deliver on an accelerating demand trajectory.
