Nano Nuclear Energy Inc. reported a larger quarterly loss as it ramps up development of its advanced microreactor and nuclear fuel businesses, but it now holds a very large cash balance from recent equity financings. For the quarter ended December 31, 2025, the company posted a net loss of $6.5 million, compared with $3.1 million a year earlier, driven mainly by higher general and administrative expenses of $6.9 million and research and development spending of $5.4 million.
The balance sheet strengthened significantly: cash and cash equivalents rose to $577.5 million and total assets reached $606.1 million, up from $228.7 million at September 30, 2025, largely due to an October 2025 private placement that raised about $400 million gross plus earlier offerings. Total stockholders’ equity increased to $599.6 million, even as the accumulated deficit widened to $64.0 million, reflecting its pre‑revenue status.
Operating cash outflow for the quarter was $4.0 million, while net cash provided by financing activities was $381.3 million. Management states it has sufficient working capital to meet obligations for at least the next 12 months as it develops its KRONOS and LOKI microreactors, fuel supply, and fuel transportation lines.
