The company does not intend to pay cash dividends on its common stock for the foreseeable future. The company has not declared or paid any cash dividends on its common stock and currently intends to retain all available funds and any future earnings for use in the operation of its business.

The company faces structural headwinds from adverse changes in political, regulatory, and economic policies of governments in connection with trade with China and Chinese customers, which have reduced demand for its products. The U.S. Department of Commerce continues to add Chinese firms to the Entity List, and these export restrictions will likely limit or prevent the company from doing business with certain potential customers or potential suppliers. The company also faces headwinds from the cyclical nature of the semiconductor industry, which is subject to wide fluctuations of supply and demand as a result of rapid technological change, rapid product obsolescence and price erosion, evolving standards, and frequent new product introductions. The company's operating results may be impacted by a decline in pricing for the current generation of its existing products, which often decreases over time.

Management has identified several constraints to the growth plan, including the company's dependence on a limited number of end customers, with one end customer representing more than 70% of revenue in 2025 ³⁰ and the top three end customers representing an aggregate of approximately 86% ³¹ of revenue. The company relies on a limited number of third-party manufacturing partners, with TSMC as its sole manufacturing partner for integrated circuits. The company's products and third-party manufacturing partners must undergo a lengthy and expensive qualification process that does not assure volume product sales. The company also faces risks from the rapid pace of developments in AI technology, and failure by customers to continue to adopt or invest in AI infrastructure could have a material adverse effect on the business.

A substantial portion of revenue is driven by a limited number of end customers; in 2025, one end customer represented more than 70% of revenue ³² and the top three end customers represented an aggregate of approximately 86% ³³ of revenue, and the loss of or a significant reduction in demand from any of these customers would materially and adversely affect operations and financial condition. The company relies on TSMC as its sole manufacturing partner for integrated circuits and has not qualified another source, creating significant supply concentration risk. Adverse changes in U.S. trade policies with China, including export controls and tariffs, have reduced demand for the company's products and damaged its business; the U.S. Commerce Department continues to add Chinese firms to the Entity List, which will likely limit or prevent the company from doing business with certain potential customers. The company's operating results are impacted by wide fluctuations of supply and demand in the highly cyclical semiconductor industry, and pricing for the current generation of existing products often decreases over time, which could negatively impact revenue and gross margins. The company has a limited history of generating net income, having recorded net income of $219.1 million ³⁴ for 2025 but net losses of $83.4 million ³⁵ and $26.3 million ³⁶ for 2024 and 2023, respectively, and may not maintain profitability if revenue growth does not outpace increasing costs.

Management's message emphasizes the company's mission to innovate, design, and deliver semiconductor-based connectivity solutions purpose-built to unleash the full potential of cloud and AI infrastructure. Management highlights the company's Intelligent Connectivity Platform, which comprises semiconductor-based, high-speed, mixed-signal connectivity products and the COSMOS software suite, as providing customers with the ability to deploy and operate high-performance cloud and AI infrastructure at scale. Management notes that the company has experienced strong growth since the commercial launch of Aries in 2020, with revenue growing from $34.8 million in 2021, $79.9 million in 2022, $115.8 million in 2023, $396.3 million in 2024, and to $852.5 million in 2025 ³⁷, driven by a sizable increase in demand for its products. Management states that the company's connectivity solutions are at the heart of major AI platforms deployed worldwide featuring both commercially available GPUs and proprietary AI accelerators, and that the company ships millions of devices across leading hyperscalers. The strategic priorities emphasized for the period ahead include continuing to develop and introduce new products and new generations of existing products, maintaining strong and collaborative relationships with hyperscaler and system OEM customers, and investing significantly in research and development to support technology and product innovation.
