Current report

The impact of pandemics may have a material adverse effect on our business, financial condition, and results of operations.

Current report

The imposition of tariffs and other trade barriers by government authorities on imported goods, including raw materials and components essential to our manufacturing processes, could have significant adverse effects on our business, financial condition, and results of operations. These tariffs may disrupt our supply chain, increase our production costs, and reduce our competitiveness in the global market.

Current report

Tariffs could cause delays and disruptions in our supply chain, as suppliers face increased costs and logistical challenges, which could result in delays in product delivery and increased inventory costs. Tariffs on imported raw materials and components could lead to higher production costs that we are unable to pass on to customers, negatively affecting our margins. Any attempts by us to pass on these increased costs to our customers through higher prices for our products may lead to reduced demand from our customers, adversely affecting our sales and market share. Additionally, tariffs may place us at a competitive disadvantage compared to foreign competitors who are not subject to similar trade barriers, which could impact our ability to compete effectively in the global market. The impact of tariffs can create economic uncertainty, which may negatively affect our customers’ purchasing decisions and overall market conditions.

Current report

We are actively monitoring changes in trade policies and tariffs and are implementing measures to mitigate these risks where feasible. Nevertheless, we cannot guarantee the success of these efforts, and the imposition of tariffs may significantly impact our business, financial condition, and results of operations.

Current report

The company may be subject to tariffs imposed by various government authorities. Any tariff implemented may not be recoverable from customers and could could have a material adverse effect on our business, financial condition, and results of operations.

Previous wording

In addition, we operate in a few narrow markets of the semiconductor market and, as a result, cyclical fluctuations may affect these segments to a greater extent than they affect the broader semiconductor market. This may cause us to experience greater fluctuations in our operating results and financial condition than compared to some of our broad line semiconductor competitors. In addition, we may experience significant changes in our profitability as a result of variations in sales, changes in product mix, changes in end-user markets and the costs associated with the introduction of new products. The markets for our products depend on continued demand in the industrial, automotive, computing, communications and consumer sectors. These end-user markets also tend to be cyclical and may also experience changes in demand that could adversely affect our operating results and financial condition.

Previous wording

A disruption in production at our manufacturing facilities could have a material adverse effect on our business. Disruptions could occur for many reasons, including fire, floods, hurricanes, typhoons, droughts, tsunamis, volcanoes, earthquakes, disease or other similar natural disasters, unplanned maintenance or other manufacturing problems, labor shortages, power outages or shortages, telecommunications failures, strikes, transportation interruption, government regulation, terrorism or other extraordinary events, including pandemics and epidemics (such as the outbreak of the COVID-19 virus) and related travel restrictions,. Such disruptions may cause direct injury or damage to our employees and property and related internal controls with significant indirect consequences. Alternative facilities with sufficient capacity or capabilities may not be available, may cost substantially more or may take a significant time to start production, each of which could negatively affect our business and financial performance. If one of our key manufacturing facilities is unable to produce our products for an extended period of time, our sales may be reduced by the shortfall caused by the disruption, and we may not be able to meet our customers’ needs, which could cause our customers to seek other suppliers. Such disruptions could have an adverse effect on our operating results and financial condition.

Previous wording

The Chinese government has provided various incentives to technology companies, including our manufacturing facilities located in Chengdu and Shanghai, China, in order to encourage development of the high-tech industry. These incentives include reduced tax rates and other measures. As a result, we are entitled to a preferential enterprise income tax rate of 15% so long as our manufacturing facilities continue to maintain their High and New Technology Enterprise (“HNTE”) status. If we were to no longer meet the HNTE requirements, our statutory tax rate for our approved Shanghai facilities would increase to 25% for any period in which an audit shows we were not compliant, which could adversely affect our operating results and financial condition. One of our manufacturing facilities and one of our wafer fabrication facilities located in Shanghai were approved for HNTE status for the tax years 2021-2023 and we expect to meet the criteria for 2024 and continue to qualify for the 15% tax rate. The Company expects to continue to meet HNTE requirements in future years. HNTE qualification requires, but is not limited to, metrics based on China research and development expenditures as well as research and development headcount and overall college-degreed headcount. Any prior years that have already been approved are subject to audit requirements. If we were to no longer meet the HNTE requirements, our statutory tax rate for our approved Shanghai facilities would increase to 25% for any period in which an audit shows we were not compliant, which could adversely affect our operating results and financial condition.

Previous wording

As of December 31, 2023, the benefit obligation of the Plan was approximately $108.1 million and the total assets in the Plan were approximately $98.0 million. Therefore, the Plan was underfunded by approximately $10.1 million. The difference between Plan obligations and assets, or the funded status of the Plan, is a significant factor in determining the net periodic benefit costs of the Plan and the ongoing funding requirements of the Plan.

Current wording

As of December 31, 2024, the benefit obligation of the Plan was approximately $95.6 million and the total assets in the Plan were approximately $88.3 million. Therefore, the Plan was underfunded by approximately $7.3 million.

Previous wording

Chinese telecoms equipment makers have sharpened Beijing’s focus on semiconductor self-sufficiency. China’s ministry of finance announced tax breaks “to support the development of integrated circuit design and the software industry,” cancelling corporate taxes for some domestic Chinese companies for two years. Although the outcome of these efforts is uncertain, the development of such capacity in China would likely have a material adverse effect on our profitability and results of operations.

Current wording

In addition to the ongoing issues regarding tariffs, China has been stepping up efforts to design and manufacture semiconductors itself rather than buy from U.S. companies, amid fears that sanctions might cripple its high-tech industry.

Previous wording

We have a significant portion of our manufacturing capacity in mainland China. In addition, in 2022 approximately 47% of our total sales were shipped to customers in China. In recent years, the Chinese economy has experienced periods of rapid expansion and wide fluctuations in the rate of inflation. In response to these factors, the Chinese government has, from time to time, adopted measures to regulate growth and contain inflation, including measures designed to restrict credit or control prices. Such actions in the future could increase the cost of doing business in China or decrease the demand for our products in China and, thereby, have a material adverse effect on our business, operating results and prospects.
