Current report
Our business is subject to numerous risks and uncertainties, including those described more fully below in this Quarterly Report on Form 10-Q. The following is a summary of principal risks and uncertainties that could materially adversely affect our business, financial condition, and results of operations. This summary should be read in conjunction with the “Risk Factors” section and should not be relied upon as an exhaustive summary of the material risks and uncertainties facing our business.
Current report
We are also a “smaller reporting company” as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and our common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

Previous wording
We have incurred net losses and negative cash flows from operations since inception and we expect to continue to incur net losses and negative cash flows from operations for the foreseeable future, due in part to our continued investment in our business. We incurred a net loss of $16.8 million and $20.0 million for the six months ended June 30, 2025 and 2024, respectively, and $39.7 million and $50.3 million for the years ended December 31, 2024 and 2023, respectively, and had an accumulated deficit of $337.0 million and $320.3 million as of June 30, 2025 and December 31, 2024, respectively. We expect our costs to increase in future periods as we continue to expend substantial resources on research and development, expansion into new markets, marketing and general administration (including expenses related to being a public company). The net losses we incur may fluctuate significantly from quarter to quarter.

Our largest end customer historically has accounted for a large portion of our sales, representing approximately 38% of our net sales for both the three and six months ended June 30, 2025. A different end customer accounted for approximately 35.5% and 30.9% of our net sales for the three and six months ended June 30, 2024, respectively. Two other single end customers directly or indirectly accounted for more than 10% of our net sales in both the three and six months ended June 30, 2025. In addition, our top ten customers accounted for approximately 98% of our total net sales for each of the three and six months ended June 30, 2025. Our top ten customers accounted for 96.1% and 95.9% for the three and six months ended June 30, 2024. We believe that our operating results for the foreseeable future will continue to depend to a significant extent on sales attributable to certain end customers.

Previous wording
The semiconductor industry requires substantial investment in research and development in order to bring to market new and enhanced solutions. Our research and development expense was $17.6 million and $18.8 million for the six months ended June 30, 2025 and 2024, respectively. We expect to increase our research and development expenditures as compared to prior periods as part of our strategy to focus on the development of new solutions, such as Apollo6, Atomiq, SoCs variants within existing Apollo families, as well as further penetration of existing markets, such as medical/healthcare, industrial edge and smart homes and buildings, and expansion into new markets such as automotive and data center and computing. We are unable to predict whether we will have sufficient resources to achieve the level of investment in research and development required to remain competitive. For example, development of our solutions using sub-threshold and near-threshold designs at 0.4 volts, 0.5 volts, or 0.6 volts costs significantly more than development at the standard 0.8 volts or 0.9 volts. This added development cost could prevent us from being able to maintain a technological advantage over larger competitors that have significantly greater resources to invest in research and development. In addition, we cannot assure you that the technologies which are the focus of our research and development expenditures will become commercially successful or generate any revenue. If we incur increased research and development costs that do not result in revenue generation, our business, financial condition and results of operations would be adversely affected.

As a result, implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future, and we cannot yet determine the impact future laws, regulations, standards, or market perception of their requirements may have on our business, and we may not be able to adequately anticipate or respond to these evolving laws or regulations. In addition, because AI-related technologies are themselves highly complex and rapidly developing, it is not possible to predict all of the legal or regulatory risks that may arise relating to our use of such technologies. New laws, guidance or decisions in this area could provide a new regulatory framework that may require us to adjust and make changes to our operations that may decrease our operational efficiency, resulting in an increase to operating costs and/or hindering our ability to improve our products and services.
Current wording
The legal and regulatory framework for our products and services, including our AI computing solutions and AI model services, is rapidly evolving as many federal, state, and foreign government bodies and agencies have introduced or are currently considering additional laws, regulations and standards related to AI. Additionally, existing laws and regulations may be interpreted in ways that would affect our or our customers’ operations, or our ability to offer our AI products and services in the markets in which we operate.

We have established international subsidiaries and have opened offices in international markets to support our activities in Asia, the Americas and Europe, and we expect to continue to conduct business with companies that are located outside the United States, particularly in Asia. This has included the establishment of offices in Taiwan and Mainland China for non-U.S. operations. We purchase wafers from foreign entities, have our products assembled and tested by subcontractors located in Asia, and supply our products to end customers located outside of the United States. Even end customers of ours that are based in the United States often use contract manufacturers based in Asia to manufacture their products, and these contract manufacturers typically purchase products directly from us. We derived 16.7% and 43.7% of our net sales for the three months ended June 30, 2025 and 2024, respectively, from end customers outside of the United States and 11.5% and 42.0%, respectively, from end customers located in Mainland China. Our international operations are subject to a number of risks, including:

Previous wording
We may experience a delay in generating or recognizing revenue for a number of reasons. Open orders at the beginning of each quarter are typically lower than expected revenues for that quarter and are generally cancelable or reschedulable with minimal notice. Accordingly, we depend on obtaining orders during each quarter for shipment in that quarter to achieve our revenue objectives and failure to fulfill such orders by the end of a quarter may adversely affect our operating results. Furthermore, we generally rely on end customers issuing purchase orders to buy our products rather than long-term supply contracts. In addition, we maintain a small infrastructure of facilities and human capital in several locations around the world and have a limited ability to reduce the expenses. Because we base our operating expenses on anticipated revenue trends and a high percentage of our expenses are fixed in the short term, any delay in generating or recognizing forecasted revenue or changes in levels of our end customers’ forecasted demand could materially and adversely impact our business, financial condition and results of operations. Due to our limited ability to reduce expenses, in the event our revenue declines, or our revenue does not meet our expectations, it is likely that in some future quarters our operating results will decrease from the previous quarter or fall below the expectations of securities analysts and investors. As a result of these factors, our operating results may vary significantly from quarter to quarter. For the six months ended June 30, 2025 and 2024, our net sales were $33.6 million and $35.5 million, respectively.

Our future success depends, in part, upon our proprietary technology and inventions. We seek to protect our proprietary technology and inventions, particularly those relating to the design of our products, through the use of patents. As of June 6, 2025, we owned 52 issued U.S. patents, 10 issued foreign patents, 22 pending U.S. patent applications, seven pending foreign patent applications, and one pending Patent Cooperation Treaty application. The issued patents in the United States generally expire beginning in 2033 through 2042. Maintenance of patent portfolios, particularly outside of the United States, is expensive, and the process of seeking patent protection is lengthy and costly. While we intend to maintain our current portfolio of patents and to continue to prosecute our currently pending patent applications and file future patent applications when appropriate, the value of these actions may not exceed their expense. Existing patents and those that may be issued from any pending or future applications may be subject to challenges, opposition, invalidation or circumvention or designed around by our competitors or declared invalid or unenforceable in judicial or administrative proceedings, and the rights granted under our patents may not provide us with meaningful protection or any commercial advantage. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.
