Access earnings results, analyst expectations, report, slides, earnings call, and transcript.
Overview
The company has revised its revenue forecast downwards and delayed the commercialization of its key product, KARNO Power Module, to 2026. Despite achieving technical milestones and signing significant partnerships, the financial performance has been weak, with increased net losses and reduced interest income. The Q&A session revealed some uncertainties, including delays in customer acceptance and manufacturing scale-up challenges. These factors, combined with a lack of immediate positive catalysts, suggest a negative sentiment, likely leading to a stock price decline of -2% to -8% over the next two weeks.
Key Financial Performance
Revenue $800,000 from research and development services in Q3 2025, compared to no revenue in Q3 2024. This increase is attributed to contracts with the Office of Naval Research, including the sale of KARNO Cores and related components, as well as testing and validation work.
Cost of Sales Approximately $800,000 in Q3 2025, resulting in a small gross loss. There was no cost of sales in Q3 2024.
Operating Expenses $15.3 million in Q3 2025, up from $14.2 million in Q3 2024. The increase is due to higher research and development costs and lower gains from asset sales in the powertrain exit and termination line.
SG&A Expenses $5.2 million in Q3 2025, down $0.5 million from Q3 2024. The decrease is due to lower facilities and insurance costs, partially offset by a small increase in labor costs.
Interest Income $2 million in Q3 2025, down from $3 million in Q3 2024. The decrease is due to a lower level of investments and lower interest rates.
Net Loss $13.3 million in Q3 2025, up from $11.2 million in Q3 2024. The increase is attributed to higher operating expenses and lower interest income.
Year-to-Date Revenue Nearly $2.8 million in 2025, all from R&D services, compared to no revenue in the same period in 2024.
Year-to-Date Operating Expenses $50.7 million in 2025, up from $47.2 million in the first three quarters of 2024. The increase is due to higher R&D expenses, partially offset by lower SG&A and powertrain exit and termination expenses.
Year-to-Date Net Loss $44 million in 2025, compared to $37.7 million in 2024. The increase is due to higher operating expenses and lower interest income.
Cash and Investment Position $164.7 million as of the end of Q3 2025, with year-to-date capital spending of $22 million primarily on additive printing machines and related equipment.

Key Q&A
Q:What vertical is the customer that shifted its acceptance of the initial KARNO units from 2025 to 2026?
A:The customer is the Navy. The ship is now in the water, undergoing sea trials, and the KARNO units are scheduled to be installed in 2026. The company plans to use some units as demonstration units for data centers and third-party validation sites before meeting the Navy's demands.
Q:Is the ship mentioned the unmanned ship that has been in development?
A:Yes, it is the unmanned ship designed for weaponry, fuel, and engines, without conventional facilities like sleeping quarters or cafeterias. The ship is designed to stay in the ocean for extended periods, and the low-maintenance KARNO technology aligns with the Navy's needs.
Q:Are the KARNO units in the parking lot undergoing testing?
A:Yes, there are customer and company-owned KARNO units in operation at the facility. The company is working on UL certification, which is expected to be completed in the next couple of months. The linear electric motor has already been certified.
Q:Has the company started testing the new regen rebuild components?
A:Yes, the new components have been implemented in both company and customer assets. The performance has improved, meeting customer needs for up to 150 kilowatts of power generation. The company plans to make minor changes to achieve 200 kilowatts of power output as they near commercialization.
Q:What is the timeline for converting the 500 units in LOI to purchase orders?
A:Some units will move from LOI to firm agreements before deployment. Customers typically need 6 to 9 months to test the units before converting to purchase orders. Demand for the product is high, and the company expects to be supply-constrained.
Q:How many customers are represented in the 500 units in LOI?
A:The LOIs represent dozens of customers, not hundreds. The company is in discussions with more potential customers, with significant interest from data centers, commercial facilities, and the military.
Q:What is the company's plan for manufacturing scale-up?
A:The company has addressed past manufacturing challenges and hired an experienced leader for operations. They have about 30 additive manufacturing machines installed and plan to optimize their performance before expanding. The focus is on improving throughput rather than immediately purchasing more machines.
Q:Why did the company decide to delay delivery or development for UL certification?
A:The company made changes to improve high and low voltage systems before UL certification to avoid re-certification later. These changes added time to the schedule but are now incorporated into the UL system.
Q:Why is KARNO considered a good fit for nuclear applications?
A:KARNO is a heat-powered generator, making it suitable for nuclear applications where heat is converted into electricity. The company is engaging with organizations in the nuclear space to replace steam turbines with KARNO for more efficient electricity production.
Q:How does the KARNO architecture align with NVIDIA's vision for data centers?
A:NVIDIA envisions data centers moving to an 800-volt DC architecture, which matches KARNO's native output. This alignment reduces costs and improves efficiency, making KARNO a suitable solution for future data center needs.
Q:Review of Unclear Management Responses
A:Management avoided providing specific details on the exact number of customers represented in the LOIs and the precise timeline for scaling up manufacturing beyond optimizing existing machines. Additionally, while they mentioned high demand and supply constraints, they did not provide concrete data or timelines for addressing these challenges.
