X-Energy, Inc. reported a significant increase in total revenues and grant income to $43.4 million for the first quarter of 2026, up from $20.8 million in the prior year. However, the company's net loss widened substantially to $166.2 million, primarily driven by a $108.9 million mark-to-market loss on warrant liabilities. Subsequent to the quarter, X-Energy, Inc. successfully completed its Initial Public Offering and related Reorganization Transactions, which also led to a significant reduction in warrant liabilities. The company also saw a substantial decrease in cash and cash equivalents and an increase in cash used in operating and investing activities.

X-Energy reported strong first quarter 2026 financial results, with total revenues and grant income increasing 109% to $43.4 million.
