Deals & partnerships

Secure Transportation Services (STS) Globally operating nuclear logistics, transportation, and services company ~$6M

Acquisition completed in May. Provides ability to transport nuclear fuel and spent fuel, expands capabilities across nuclear fuel cycle, and de-risks Kronos advancement. Initial payment was approximately $7M.

unnamed strategic collaborator and AI infrastructure company Potential preferred nuclear technology provider for planned multi-gigawatt AI data centers potential milestone-based investments (tens of millions, if not $100M) long-term interests

Partner has experience building, owning, and operating large infrastructure projects globally. Framework designed to align long-term interests and incentivize joint success, with partner potentially purchasing NANO's reactors.

Bonn-Rupon Feasibility study for phased deployment of up to 1 gigawatt of Kronos MMR capacity

Evaluated a phased deployment of up to 1 gigawatt of Kronos MMR capacity.

Supermicro MOU to evaluate integration of Kronos with Supermicro's AI server and data center infrastructure platforms

Jointly evaluating how nuclear-powered data centers may be designed as integrated systems.

F-Works (Department of the Air Force) SBIR Phase I award to advance Kronos MMR for US Air Force

Follows previously announced direct phase two SPR award for Joint Base Anacostia Bowling, which continues to progress on schedule.

unnamed Additional fuel transportation business

Synergistic acquisition opportunity to expand STS's capabilities, geographic footprint, and revenue base.

unnamed Nuclear fuel facility assets

Synergistic acquisition opportunity to further de-risk the nuclear fuel cycle. Equity position would be earned through investment into the completion of the facility.

Capital programs

Kronos MMR deployment at University of Illinois underway
Funding: potential non-dilutive funding opportunities (investment tax credits, DOE programs, UOI/state of Illinois support)

Benefit:full-scale 15 megawatt electric unit

NRC formally accepted construction permit application for review; initial construction activities expected H2 2027. This is a research reactor, saving on NRC licensing fees.

Risks & headwinds

Operating Expense Increase Q3 FY26

Operating expenses totaled $15.9M in Q3 FY26, driving net loss increase to $10.1M from $7.6M YoY.

Mitigation:Scaling engineering, regulatory, commercial, and fuel cycle workstreams; strategic capital deployment.

Fuel Supply Chain Execution Coming decade

Not quantified, but stated as "one of the greatest challenges facing advanced nuclear industry over the coming decade."

Mitigation:Strategic focus on expanding capabilities (STS acquisition, M&A/partnership discussions for fuel facility assets).

HALU Availability Future (currently not available)

Not quantified.

Mitigation:Kronos designed to utilize LEU Plus fuel (commercially available today) while maintaining flexibility for HALU without redesign once available.

Fast Reactor Deployment Challenges Ongoing

Not quantified.

Mitigation:NANO's Kronos is a high-temperature gas-cooled reactor (HTGR) which has demonstrated deployment history and uses available fuel, unlike fast reactors which lack commercial deployment history, require highly enriched fuel, and are difficult to scale down.

Why it matters

Key regulatory milestone for UIUC project, de-risking first deployment.

The NRC subsequently announced its expectation to complete its environmental assessment in Q1 2027 and its safety evaluation in Q3 2027.

Q&A highlights

Are there any long-lead items that need to be ordered now to start construction in H2 2027 for the UIUC project?

Initial construction focuses on subterranean concrete structures, not reactor components, so no long-lead reactor components are immediately needed. Non-nuclear components for the thermal energy storage system are standard and can be constructed without NRC approval. Sourcing for reactor components has begun, aiming to have everything known by approval next year.

“So the initial construction fortunately focuses more on things like the installation of the citadel. So if you think about a big subterranean concrete structure for which the reactor will sit in. For instance, technically right at the start of the construction period, we don't need any reactor related components.”

Detailed narrative

Kronos MMR Development & Licensing

The NRC formally accepted the construction permit application for the Kronos MMR at the University of Illinois, Urbana-Champaign, initiating formal review activities. The NRC expects to complete its environmental assessment in Q1 2027 and safety evaluation in Q3 2027, aligning with NANO's expectation to begin initial construction activities in H2 2027.

Engineering collaborations with Fortil and another globally recognized firm are advancing the Kronos fuel handling and storage system and primary helium circulator, maturing key reactor subsystems and establishing repeatable designs for future standardized commercial deployments.

Vertical Integration & STS Acquisition

NANO completed the acquisition of Secure Transportation Services (STS) in May, accelerating its progress in the nuclear fuel cycle. STS, a profitable nuclear logistics and transportation company, generated $3.9 million of unaudited revenue in H1 2026, including $0.2 million from May 22nd through June 30th.

This acquisition reduces reliance on third-party providers, expands capabilities across the fuel cycle, and supports critical missions for the U.S. DOE and NNSA. NANO is also evaluating additional M&A opportunities in fuel transportation and nuclear fuel facility assets.

Commercial Pipeline Expansion

The company is advancing discussions towards an initial framework with a strategic collaborator and customer for a planned multi-gigawatt pipeline of AI data center projects, potentially positioning NANO as their preferred nuclear technology provider. A feasibility study for deploying up to 1 gigawatt of Kronos MMR capacity with Bonn-Rupon was completed, with discussions progressing towards initiating the NRC licensing process.

NANO also signed an MOU with Supermicro to evaluate integrating Kronos with AI server and data center infrastructure platforms for joint go-to-market opportunities and off-grid deployments.

Financial Strength & Capital Allocation

NANO ended the quarter with $580 million in liquidity, an increase of $11 million from the prior quarter, primarily due to $26 million in net proceeds from its at-the-market (ATM) facility. This strong financial position provides flexibility to advance the first-of-a-kind prototype deployment and pursue value-accretive acquisitions across the fuel cycle.

The company is also exploring non-dilutive funding opportunities for the UIUC project, including investment tax credits and DOE programs, to meaningfully reduce required capital.

Team Growth & Expertise

The team has grown significantly over the past year, with headcount increasing to 85 employees and contractors as of Q3 FY26, up from 31 one year prior. NANO has assembled an experienced team from the DOE, NRC, U.S. National Labs, and military, and expects further significant growth, particularly in technical staff.

This expansion is crucial for carrying reactor projects forward and supporting fuel supply chain initiatives, with a focus on sensible hiring to ensure proper allocation and task designation.

Fuel Cycle Strategy

Kronos is designed for fuel flexibility, utilizing LEU Plus fuel commercially available today, with the ability to use HALU in the future without redesign. NANO is actively engaging with enrichment providers like Urenco for LEU and emerging Triso fabricators (e.g., B2XT, Standard Nuclear, Framatome, TrisoX) to secure long-term contracts.

The company aims to de-risk the nuclear fuel cycle by expanding capabilities in fuel transportation, conversion, and deconversion, ensuring fuel supply for mass manufacturing of reactors beyond the first-of-a-kind deployment.
