Yahoo Finance analysis indicates that fuel cell manufacturer Bloom Energy achieved revenues of nearly $2 billion in fiscal year 2025, marking a year-over-year increase of approximately 37.3%, but incurred a net loss of nearly $88.4 million during the same period. The company's debt-to-equity ratio was about 3.9x, with free cash flow at $57.2 million. The article suggests that Bloom Energy has found markets in areas such as AI data centers. In contrast, NANO Nuclear Energy, a developer of portable micro-nuclear reactor technology, reported zero revenue and a net loss of approximately $40.1 million in fiscal year 2025. Although its technology holds potential, it is still in the development phase, and commercialization will take time.
