Our current liabilities were $14.3 million primarily comprised of accounts payable, accrued expenses and operating lease liabilities.

Based on our past performance, we believe our current and long-term assets will be sufficient to continue and execute on our business strategy and meet our capital requirements for the next twelve months. Our primary short-term cash needs are costs associated with KARNO generator development, building our initial deployment units and capital investments for additive printer acquisitions. Longer term, our capital needs will be determined by our go-to-market strategy as well as governmental R&D, which may include development of our own KARNO generator manufacturing capacity or outsourcing this work to third parties or business partners. In December 2023, we announced an authorized share repurchase program to repurchase up to $20 million of our outstanding common stock. We repurchased $14.0 million in common stock during the year ended December 31, 2024 but have currently paused any additional repurchases under this program. Based on current projections of operating expenses, capital spending, working capital growth and historical share repurchases, we expect to have approximately $160 million in cash, short-term and long-term investments remaining on our balance sheet at the end of 2025.

It is possible that this financing could be delayed or may not occur at all if acceptable terms cannot be obtained.

The amount and timing of our future funding requirements, if any, will depend on many factors, including the scope and results of our R&D efforts, the breadth of product offerings we plan to commercialize, the growth of sales, working capital needs, and our long-term manufacturing plan for the KARNO generator including the pace of investments in additive manufacturing assets, methods of financing these investments, as well as factors that are outside of our control. We regularly evaluate our funding needs and sources of capital and may seek external funding in the appropriate circumstances.

We regularly evaluate our funding needs and sources of capital and may seek external funding in the appropriate circumstances. While we expect that we have sufficient capital to get through commercialization of the KARNO Power Module, we do anticipate that, at some time, we will seek additional sources of capital to accelerate investments in assets needed for growth following commercialization, primarily additive printing machines and related assets. With our current cash and investments, we believe we are well positioned to be deliberate and opportunistic in determining the timing and structure of a capital raise.

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the balance sheet date, as well as the reported expenses incurred during the reporting period. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates, and such differences could be material to our financial statements.

The Company performs under three contracts as both a prime and subcontractor to the United States government to provide R&D services, primarily to research the suitability of its KARNO generator for Navy ships and stationary power applications on a best effort cost-plus-fixed fee basis. The transaction price allocated to the remaining unsatisfied performance obligations under these contracts was up to $15.7 million as of December 31, 2024, which is expected to be recognized in 2025 and 2026. There is a single research and development services performance obligation in each of these contracts that is measured over time as the services are performed. The Company generally invoices monthly which corresponds directly with the value to the customers of the performance completed to date, and recognizes revenue in the amount that it has a right to invoice. Payment is ordinarily due within 90 days of invoice submission.

Through December 31, 2024, we have not yet commercialized the KARNO generator. Costs incurred for components acquired prior to our determination of reaching a commercial stage are expensed as R&D costs, resulting in zero cost basis for those components. As a result, moving-average prices for inventory that is capitalized in future periods may be significantly affected by those zero cost items. Inventory is consumed in the performance of R&D revenue contracts in the quarter in which it is purchased and we therefore do not record inventory at each reporting period pertaining to these contracts.

If factors change, and we utilize different assumptions including the probability of achieving performance conditions, share-based compensation cost on future award grants may differ significantly from share-based compensation cost recognized on past award grants. If there are any modifications or cancellations of the underlying unvested securities, we may be required to accelerate any remaining unearned share-based compensation cost or incur incremental cost. Share-based compensation cost affects our R&D and selling, general and administrative expenses.
