NANO Nuclear Energy Inc. (NASDAQ: NNE) saw its stock surge approximately 24.6% in Wednesday trading after the company announced a non-binding memorandum of understanding (MOU) with Super Micro Computer Inc. (NASDAQ: SMCI) to explore the use of NANO's KRONOS micro modular reactors (MMRs) as a power source for AI data centers. Supermicro shares also climbed 21.4% on the news, buoyed by a better-than-expected fiscal outlook.
The agreement, which remains in an exploratory phase, outlines a framework for collaboration to integrate NANO's KRONOS MMR energy system with Supermicro's server racks, AI hardware, cooling solutions, and support services. However, the MOU does not constitute a binding supply contract, and no revenue forecasts or reactor approvals have been disclosed.
The announcement comes amid growing concerns over power supply constraints for the AI sector. Reuters reported Wednesday that Microsoft is considering delaying or abandoning its 2030 clean-power matching target, citing surging data-center demand. Separately, Exelon has increased its capital spending plan, pointing directly to robust power needs and data-center expansion.
NANO sees the deal as a potential entry point into hyperscale, enterprise, and edge data-center markets, even as the company remains in early development stages. The MOU simply sets the stage for further discussions and collaboration, with no guarantee of progressing to binding agreements or revenue-generating projects.
By mid-afternoon in New York, NANO shares had risen to $28.37, giving the company a market capitalization of approximately $1.41 billion. Supermicro closed at $33.78. Other advanced nuclear stocks also moved higher: NuScale Power rose 12.0%, and Oklo gained 13.9%.
Supermicro provided additional momentum by posting fiscal Q3 net sales of $10.2 billion and projecting fourth-quarter sales between $11 billion and $12.5 billion. CEO Charles Liang stated that the shift to a full-scale datacenter infrastructure provider is accelerating.
Jay Yu, chairman and president of NANO, described AI as "fundamentally an energy challenge." CEO James Walker said the companies are working toward "compute and power becoming a unified solution," echoing the industry's desire for dedicated electricity supply to bypass grid delays.
The KRONOS MMR is a micro modular reactor designed to deliver nuclear energy on a much smaller scale than traditional plants. On March 31, the University of Illinois Urbana-Champaign announced that its Grainger College of Engineering had filed a construction permit application with the U.S. Nuclear Regulatory Commission, in partnership with NANO, to bring a KRONOS reactor to campus.
Despite the market enthusiasm, NANO remains an early-stage company. According to its latest quarterly filing, the company has not generated material revenue since inception through December 31, 2025, and has accumulated losses of $64.0 million. Management has indicated that additional funding will be needed as reactors progress toward commercialization. Cash and cash equivalents stood at approximately $578 million at the end of 2025.
Execution risks remain significant. NANO acknowledged in the MOU filing that there is no guarantee it will lead to binding deals or revenue-generating projects. The company cited regulatory hurdles, design and testing requirements, budget overruns, the need for more funding, and the timing of commercial rollout as ongoing sources of uncertainty.
