X-Energy, Inc.XE

X-Energy, Inc. (XE), a developer of advanced nuclear reactor technology, reported a net loss of $166.2M for the quarter ending 2026-03-31, despite revenues and grant income of $43.4M. The company’s latest 10-Q filing reveals a cash position of $224.1M and short-term investments of $449.5M, but operating activities burned through $67.3M in the same period. This financial strain comes as XE pushes forward with its Xe-100 high-temperature gas-cooled reactor (HTGR), designed to provide both grid-scale power and industrial thermal energy.

X-Energy’s business model hinges on its ability to deliver advanced nuclear technology solutions, including the Xe-100 and the XENITH micro-mobile nuclear reactor. The Xe-100 is marketed as a reliable, safe, and clean energy source, capable of converting nuclear energy into electricity or industrial steam. The company’s collaboration with LG&E and KU, subsidiaries of PPL Corporation, to explore deploying Xe-100 SMRs in Kentucky highlights its efforts to meet growing energy demand, particularly for data centers and other large load customers.

The latest financial filings show that X-Energy’s operating income (loss) stood at $-66.1M for the quarter ending 2026-03-31. The company’s assets totaled $1.20B, while liabilities were $150.1M, leaving stockholders’ equity attributable to the parent at $-1.39B. These figures underscore the financial challenges XE faces as it seeks to scale its nuclear technology. Research and development expenses for the quarter were a modest $55,000, indicating that the company may be focusing more on operational scaling rather than innovation at this stage.

For those following XE’s progress, the company’s submission of the Xe-100 HTGR for UK Generic Design Assessment is a significant milestone. Administered by the UK Office for Nuclear Regulation (ONR), Environment Agency, Natural Resources Wales, and the Department for Energy Security and Net Zero (DESNZ), the assessment is expected to conclude by the end of 2029. This regulatory process will be crucial for XE’s international expansion plans. The company’s latest 8-K filing, dated 2026-06-04, provides further insights into its operational and financial status.
