FuelCell Energy is a Connecticut-based company that designs and manufactures high-temperature fuel cells for clean electricity generation, serving utilities, data centers, and industrial customers [Company Overview]. The company is pre-profit and burning significant cash, with a negative gross margin of -16.7% and free cash flow of -$147.8M [Yahoo Finance]. Recent stock volatility reflects a sharp 22% single-day drop after a 130% one-month rally driven by an AI data center platform launch [Yahoo Finance].

The company is deeply unprofitable with razor-thin revenue relative to its market cap, signaling significant execution risk.
