For ease of reference, we have divided these risks and uncertainties into the following general categories: I. Summary Risk Factors; II. Risks Related to Our Business and Operations; III. Risks Related to International Aspects of Our Business; IV. Risks Related to Our Financial Results and Capital Structure; V. Risks Related to Our Intellectual Property; and VI. Risks Related to Compliance, Environmental Regulations and Other Legal Matters. 58 Table of Contents I. Summary Risk Factors ● Global economic and political conditions, including trade tariffs, import-export restrictions, and other restrictions, may have a negative impact on our business and financial results. China's requirement of export permits for InP is an example. We are subject to a number of unique legal and operational risks associated with our corporate structure. ● The PRC central government may intervene in or influence our PRC operations at any time and the rules and regulations in China can change quickly with little advance notice. ● Although the audit report included in our Annual Report was prepared by an independent registered public accounting firm who is currently inspected fully by the Public Company Accounting Oversight Board (the “PCAOB”), there is no guarantee that future audit reports will be prepared by an independent registered public accounting firm that is completely inspected by the PCAOB. ● Our NASDAQ stock price is volatile and our stock price could decline. Unpredictable fluctuations in our operating results, export permit requirements, changes and events in our end markets and global trends cause volatility in our stock price. ● We face litigation and legal proceedings which could adversely affect our business, financial condition, results of operations or cash flows. ● Changes in China’s political, social, regulatory or economic environments may affect our financial performance. ● The Chinese central government is increasingly aware of air pollution and other forms of environmental pollution and their reform efforts can impact our manufacturing, including intermittent mandatory shutdowns. Shutdowns or underutilizing our manufacturing facilities may result in declines in our gross margins. ● Escalating and volatile trade tariffs, import restrictions, export restrictions, Chinese regulations or other trade barriers may materially harm our business. ● If China places restrictions on freight and transportation routes and on ports of entry and departure this could result in shipping delays or increased costs for shipping. ● Our international operations are exposed to potential adverse tax consequence in China. ● Our gross margin has fluctuated historically and may decline or increase due to several factors. Factors such as product mix, unit volume, yields and other manufacturing efficiencies can cause our gross margin to decrease or increase from quarter to quarter. ● The terms of the private equity raised by Tongmei in China grant each investor a right of redemption if the IPO fails to pass the audit of the Shanghai Stock Exchange, is not approved by the CSRC or Tongmei cancels the IPO application. On July 8, 2026, the STAR Market accepted Tongmei's withdrawal of its IPO application.. In the event, all the Investors exercise their full redemption rights this would result in returning the $49 million that we raised from these Investors. ● Defects in our products could diminish demand for our products. Our ability to receive orders from tier one customers is contingent on producing wafer substrates of very high quality and deploying best practices in manufacturing. We may not always be able to meet these requirements and we could then lose revenue. ● Difficulties in accurately estimating market demand could result in over-investing in inventory, equipment and capacity expansion or losing market share if we do not invest sufficiently. ● Attracting and retaining tier one customers requires that we succeed in our research and development programs. Customers establish difficult to meet product specifications regarding defect densities, surface flatness, diameter size and other specifications pushing the boundaries of material science. We may not achieve these specifications. ● We are subject to foreign exchange gains and losses that materially impact our condensed consolidated statements of operations. Because we are a global company we are exposed to changes and swings in foreign exchange, particularly when currencies experience periods of volatility. ● Joint venture raw material companies in China bring certain risks. ● We derive a significant portion of our revenue from international sales, and our ability to sustain and increase our international sales involves significant risks. ● Long-term supply agreements with customers, including those involving customer prepayments, may not result in anticipated revenue or profitability and create obligations to deliver products or services in the future. If we are unable to fulfill our contractual obligations or if customer demand or market conditions change, our revenue, liquidity and results could be adversely affected. 59 Table of Contents II. Risks Related to Our Business and Operations Global economic and political conditions, including trade tariffs, import-export restrictions, and other restrictions, may have a negative impact on our business and financial results. China's requirement of export permits for InP is an example. In September 2018, the United States announced a list of thousands of categories of goods that became subject to Section 301 tariffs when imported into the United States from China. This pronouncement imposed tariffs on wafer substrates we imported into the United States. The initial tariff rate was 25%. On July 3, 2023, China announced new export control regulations on materials including gallium and germanium and compounds of these materials, effective as of August 1, 2023. Materials that could be used in military applications, specifically including weapons of mass destruction, were the primary focus. This required Tongmei to seek permits from the applicable Chinese authorities to export gallium arsenide and germanium substrates. Since that time, a general escalation has been underway with further increases to the tariffs from the US and additional export controls from China, including for InP wafers. The escalating requirements resulted in a new layer of administration within our company. Each order needs the customer to certify in writing that our wafer substrates will not be used in military applications and must state the end use of our products. This is a labor intensive process and has extended the cycle time in order fulfillment. To ensure compliance in trade matters we have consulted with legal experts and incurred additional legal costs. The rapid pace of change and new regulations in trade matters results in more internal administrative review and costs. In late 2024 and early 2025, a new round of trade restrictions was announced by China and the United States. On December 3, 2024, China issued further rules restricting exports of materials that can typically be used in military applications including antimony, gallium, germanium and other superhard materials. The effective date was December 3, 2024, the same day as the announcement itself. Reciprocally, the United States increased tariffs on many items from China from 25% to 50%, effective January 1, 2025. On February 1, 2025, the United States again further increased the tariff on imports of many products from China, including our wafer substrates, to 60%. On February 4, 2025, China began to require export permits on InP wafers. This requirement remains major concern for AXT. On March 4, 2025, the United States further increased the tariff on imports of many products, including our wafer substrates, to 70%. On December 27, 2025, the Standing Committee of the National People’s Congress of China (“NPC”) enacted substantial revisions to the Foreign Trade Law of the People’s Republic of China, effective March 1, 2026 (the “Foreign Trade Law”). The revisions to the Foreign Trade Law provide, among other things, enhanced power vested in governmental agencies to prohibit or restrict the import or export of goods and technologies for a variety of reasons set forth in Article 18 of the Foreign Trade Law, including, but not limited to, (i) safeguarding national security, (ii) where there is a domestic shortage of supply or to protect potentially depleted natural resources, (iii) in order to establish or accelerate the establishment of specific domestic industries, and (iv) other circumstances where it is necessary to prohibit or restrict the import or export of relevant goods or technologies, or take other necessary measures. The revisions also include a chapter on intellectual property introducing new trade sanctions for the infringement of intellectual property rights when such infringement endangers the order of foreign trade and targets specific licensing practices that prohibit the challenge of a license’s validity or portfolio licensing bundling. The specific prohibitions and restrictions on the import and export of goods and technologies are delegated to the Ministry of Commerce of the People’s Republic of China, among other agencies. While we do not believe that the revisions will have any additional material adverse effects on our wafer substrate products beyond the current restrictions and licensing requirement, however, with the Foreign Trade Law’s enhanced power over import and export prohibitions and restrictions, no assurances can be given that additional restrictions will not be imposed in the future. On February 20, 2026, the U.S. Supreme Court invalidated many of the global tariffs previously imposed under the International Emergency Economic Powers Act of 1977 (the "IEEPA") and the U.S. Customs and Border Protection subsequently announced that IEEPA-based tariff provisions would be terminated effective February 24, 2026. However, tariffs imposed under other authorities, including Section 232 of the Trade Expansion Act of 1962 and Section 301 of the Trade Act of 1974, remain in effect, and the U.S. government has indicted that it may pursue additional or replacement tariffs under alternative legal authorities, including temporary measures under Section 122 of the Trade Act of 1974. If maintained, these announced new tariffs, as well as related measures that could be taken by other countries and the potential escalation of trade disputes, could affect our business and results of operations. Indium phosphide substrates are the primary revenue generator derived from imports into the U.S. This revenue has been impacted by additional tariffs imposed by the United States and by export controls implemented by China. In 2024, 8% of our total worldwide revenue was from sales in North America, primarily in the U.S.; however, in 2025, only approximately 2% of our revenue was generated by sales to customers in North America. All of our wafer substrates are manufactured in China. In the years 2025, 2024 and 2023, approximately 2%, 8% and 10% of our revenue, respectively, were generated by sales to customers in North America, primarily in the U.S. In the years 2025, 2024 and 2023, we paid approximately $0.3 million, $1.0 million and $1.0 million, respectively, in tariffs. The trade and political tensions between China and the U.S. remain high and controls on exports and tariffs are changing and fluid. 60 Table of Contents Silicon substrates (wafers) are significantly lower in cost compared to substrates made from specialty materials, such as those that we produce, and new silicon-based technologies could enable silicon-based substrates to replace specialty material-based substrates for certain applications. Historically silicon wafers or substrates are less expensive than specialty material substrates, such as those that we produce. Electronic circuit designers will generally consider silicon first and only turn to alternative materials if silicon cannot provide the required functionality in terms of power consumption, speed, wave lengths or other specifications. Beginning in 2011, certain applications that had previously used GaAs substrates, specifically the RF chip in mobile phones, adopted a new silicon-based technology called silicon on insulator, or SOI. SOI technology uses a silicon-insulator-silicon layered substrate in place of conventional silicon substrates in semiconductor manufacturing. SOI substrates cost less than GaAs substrates and, although their performance is not as robust as GaAs substrates in terms of power consumption, heat generation and speed, they became acceptable in mobile phones and other applications that were previously dominated by GaAs substrates. The adoption of SOI resulted in decreased GaAs wafer demand, and decreased revenue. If SOI or new silicon-based technologies gain more widespread market acceptance, or are used in more applications, our sales of specialty material-based substrates could be reduced and our business and operating results could be significantly and adversely affected. Our gross margin has fluctuated historically and may decline due to several factors. Our gross margin has fluctuated from period to period as a result of increases or decreases in total revenue, unit volume, shifts in product mix, shifts in the cost of raw materials, costs related to the relocation of our gallium arsenide and germanium production lines, including costs related to hiring additional manufacturing employees at our new locations, tariffs imposed by the U.S. government, the introduction of new products, decreases in average selling prices for products, utilization of our manufacturing capacity, fluctuations in manufacturing yields and our ability to reduce product costs. These factors and other variables change from period to period and these fluctuations are expected to continue in the future. For example, in the third quarter of 2022 our gross margin was 42.0% but it dropped to 10.7% in the third quarter of 2023 as a result of several of these factors. In the first quarter of 2025, our gross margin was a negative 6.4% but improved to 8.0% in the second quarter of 2025; in the third quarter of 2025, our gross margin has further improved to 22.3%. However, there can be no assurance that our gross margin will not fluctuate in future periods due to ongoing uncertainty of various factors. Our raw material companies experience selling price volatility and purchase price volatility in acquiring base materials. We consolidate the results of two of these raw material companies, and any reduction in their gross margins could have a significant, adverse impact on our overall gross margins. One or more of our companies has in the past sold, and may in the future sell, raw materials at significantly reduced prices in order to gain volume sales or sales to new customers. In addition, the market price of gallium dropped below our per unit inventory cost and we incurred an inventory write down under the lower of cost or net realizable value accounting rules. Shutdowns or underutilizing our manufacturing facilities may result in declines in our gross margins. An important factor in our success is the extent to which we are able to utilize the available capacity in our manufacturing facilities. A number of factors and circumstances may reduce utilization rates, including periods of industry overcapacity, low levels of customer orders, operating inefficiencies, mechanical failures and disruption of operations due to expansion, power interruptions, fire, flood, other natural disasters or calamities or government-ordered mandatory factory shutdowns, including as a result of the health epidemics or outbreaks such as during the COVID-19 pandemic. Severe air pollution in Beijing can trigger mandatory factory shutdowns. For example, in the first quarter of 2018, over 300 manufacturing companies, including Tongmei, were intermittently shut down by the local government for a total of ten days from February 27 to March 31, due to severe air pollution. Further, we have increased capacity by adding two new sites and this could reduce our utilization rate and increase our depreciation charges. Because many portions of our manufacturing costs are relatively fixed, high utilization rates are critical to our gross margins and operating results. If we fail to achieve acceptable manufacturing volumes or experience product shipment delays, our results of operations will be negatively affected. During periods of decreased demand, we have underutilized our manufacturing lines. If we are unable to improve utilization levels at our facilities during periods of decreased demand and correctly manage capacity, the fixed expense levels will have an adverse effect on our business, financial condition and results of operations. For example, in the three months ended September 30, 2023, our revenue dropped to $17.4 million and our gross margin was only 10.7%. 61 Table of Contents If we are unable to utilize the available capacity in our manufacturing facilities, we may need to implement a restructuring plan, which could have a material adverse effect on our revenue, our results of operations and our financial condition. For example, in 2013, we concluded that incoming orders were insufficient and that we were significantly underutilizing our factory capacity. As a result, in February 2014, we announced a restructuring plan with respect to our China company, Tongmei, in order to better align manufacturing capacity with demand. Under the restructuring plan, we recorded a charge of approximately $907,000 in the first quarter of 2014. If we receive fewer customer orders than forecasted or if our customers delay or cancel orders, we may not be able to reduce our manufacturing costs in the short-term and our gross margins would be negatively affected. In addition, lead times required by our customers are shrinking, which reduces our ability to forecast orders and properly balance our capacity utilization. Cyber-attacks, system security risks and data protection issues could disrupt our internal operations and cause a reduction in revenue, increase in expenses, negatively impact our results of operations or result in other adverse consequences. Like most technology companies, we could be targeted in cyber-attacks. We face a risk that experienced computer programmers and hackers may be able to penetrate our network security and misappropriate or compromise our confidential and proprietary information, potentially without being detected. Computer programmers and hackers also may be able to develop and deploy viruses, worms, and other malicious software programs that attack our information technology infrastructure and demand a ransom payment. The costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant, and our efforts to address these problems may not be successful and could result in interruptions and delays that may impede our sales, manufacturing, distribution, accounting or other critical functions. Breaches of our security measures could create system disruptions or cause shutdowns or result in the accidental loss, inadvertent disclosure or unapproved dissemination of proprietary information or sensitive or confidential data about us. Cyber-attacks could use fraud, trickery or other forms of deception. In addition, the rapid evolution of AI has the potential to disrupt existing business models and markets and could result in a material adverse effect on our business. The increased adoption of AI technologies may also increase our cybersecurity risks. A cyber-attack could expose us to a risk of loss or misuse of information, result in litigation and potential liability, damage our reputation or otherwise harm our business. In addition, the cost and operational consequences of implementing further data protection measures could be significant. Portions of our information technology infrastructure might also experience interruptions, delays or cessations of service or produce errors in connection with systems integration or migration work that takes place from time to time, which may have a material impact on our business. We may not be successful in implementing new systems and transitioning data, which could cause business disruptions and be more expensive, time consuming, disruptive and resource-intensive than originally anticipated. Such disruptions could adversely impact our ability to fulfill orders and interrupt other processes. Delayed sales, lower margins or lost customers could adversely affect our financial results and reputation. We may become subject to risks associated with artificial intelligence and machine learning technologies. Artificial intelligence, including machine learning technology (collectively, “AI”), is complex and rapidly evolving. While the full extent of current or future risks related thereto is not possible to predict, AI could significantly disrupt the business models and markets in which we operate and subject us to increased competition, legal and regulatory risks and compliance costs, any of which could have a material adverse effect on our business, financial condition and results of operations. Although we do not currently utilize AI to a significant extent in our operations, any future potential integration of AI technologies into our operations, any new regulations related to AI may also impose on us certain obligations and costs related to monitoring and compliance, and we could be subject to regulatory actions if we or they are deemed not to have complied. 62 Table of Contents We face risks related to health epidemics and other outbreaks, which could significantly disrupt our business operations. The spread of a novel strain of coronavirus (COVID-19) around the world in the first quarter of 2020, which was declared a pandemic by the World Health Organization in March 2020, significantly impacted our operations and financial performance. In early 2020, in response to intensifying efforts to contain the spread of COVID-19, the Chinese government took a number of actions, which included, among others, ordering companies to remain closed after the traditional Lunar New Year holiday ended, which included our subsidiaries in China, and restricting travel between China and the U.S.. In December 2022, the PRC government ended its zero-COVID policy. If there are future outbreaks or future health epidemics in cities in which our PRC subsidiaries and PRC joint ventures are located, the Chinese government may require these companies to close again. If one or more of our key suppliers is required to close for an extended period, we might not have enough raw material inventories to continue manufacturing operations. In addition, travel restrictions between China and the U.S. were disrupted and this impacted our efficiency. In the future, if our manufacturing operations were closed for a significant period or we experience difficulty in shipping our products, we could lose revenue and market share, which would depress our financial performance and could be difficult to recapture. If one of our key customers is required to close for an extended period, this may delay the placement of new orders. As a result, our revenue would decline. If we have low product yields, the shipment of our products may be delayed and our product cost and operating results may be adversely impacted. A critical factor in our product cost is yield. Our products are manufactured using complex crystal growth and wafer processing technologies, and the number of usable wafer substrates we produce can fluctuate as a result of many factors, including: ● poor control of furnace temperature and pressure during crystal growth; ● impurities in the materials used; ● contamination of the manufacturing environment; ● quality control and inconsistency in quality levels; ● lack of automation and inconsistent processing requiring manual manufacturing steps; ● substrate breakage during the manufacturing process; and ● equipment failure, power outages or variations in the manufacturing process. An example where yield is of special concern is for our six-inch semi-conducting gallium arsenide substrates, which can be used for manufacturing industrial lasers and LED lighting. These applications require very low defect densities, also called EPD, and our yields will be lower than the yields achieved for the same substrate when it will be used in other applications. If we are unable to achieve the targeted quantity of low defect density substrates, then our manufacturing costs would increase and our gross margins would be negatively impacted. In addition, we may modify our process to meet a customer specification, but this can impact our yields. If our yields decrease, our revenue could decline if we are unable to produce products to our customers’ requirements. At the same time, our manufacturing costs could remain fixed, or could increase. Lower yields negatively impact our gross margin. We have experienced product shipment delays and difficulties in achieving acceptable yields on both new and older products, and such delays and poor yields have adversely affected our operating results. We may experience similar problems in the future and we cannot predict when they may occur, their duration or severity. If our manufacturing processes result in defects in our products making them unfit for use by our customers, our products would be rejected, resulting in compensation costs paid to our customers, and possible disqualification. This could lead to revenue loss and market share loss. 63 Table of Contents Problems incurred in our raw material companies or our investment partners could result in a material adverse impact on our financial condition or results of operations. We have invested in raw material companies in China that produce materials, including 99.99% pure gallium (4N Ga), high purity gallium (6N and 7N Ga), arsenic, germanium, germanium dioxide, pyrolytic boron nitride (pBN) crucibles and boron oxide (B2O3). We purchase a portion of the materials produced by these companies for our use and they sell the remainder of their production to third parties. We consolidate the companies in which we have a majority or controlling financial interest and employ equity accounting for the companies in which we have a smaller ownership interest. Several of these companies occupy space within larger facilities owned and/or operated by one of the other investment partners. Several of these partners are engaged in other manufacturing activities at or near the same facility. In some facilities, we share access to certain functions, including water, hazardous waste treatment or air quality treatment. If a partner in any of these ventures experiences problems with its operations, or deliberately withholds or disrupts services, disruptions in the operations of our companies could occur, having a material adverse effect on the financial condition and results of operation in these companies, and correspondingly on our financial condition or results of operations. For example, since gallium is a by-product of aluminum, our raw gallium company in China, which is housed in and receives services from an affiliated aluminum plant, could generate lower production and shipments of gallium as a result of reduced services provided by the aluminum plant. Accordingly, in order to meet customer supply obligations, our supply chain may have to source materials from another independent third-party supplier, resulting in higher costs and reduced gross margin. The China central government has tightened control over hazardous chemicals and other hazardous materials. Further, the central government encourages employees to report to the appropriate regulatory agencies possible safety or environmental violations, but there may not be actual violations. Regular use in the normal course of business of hazardous chemicals or hazardous materials or a company’s failure to meet the ever-tightening standards for control of hazardous chemicals or hazardous materials could result in orders to shut down permanently, fines or other severe measures. Any such orders directed at one of our raw material companies could result in impairment charges if the company is forced to close its business, cease operations or incurs fines or operating losses, which would have a material adverse effect on our financial results. Further, some of our raw material companies share facilities with our raw material investment partners. If either company is deemed to have violated applicable laws, rules or regulations governing the use, storage, discharge or disposal of hazardous chemicals, their operations could be adversely affected and we could be subject to substantial liability for clean-up efforts, personal injury, fines or suspension or termination of operations. Employees working for these companies could bring litigation against us even though we are not directly controlling those operations. While we would expect to defend ourselves vigorously in any litigation that is brought against us, litigation is inherently uncertain and it is possible that our business, financial condition, results of operations or cash flows could be affected. Even if we are not deemed responsible for the actions of the raw material companies or investment partners, litigation could be costly, time consuming to defend and divert management attention; in addition, if we are deemed to be the most financially viable of the partners, plaintiffs may decide to pursue us for damages. Our financial performance can be adversely affected if there are unfavorable financial results in any of our raw material companies. The raw material companies in our vertically integrated supply chain have historically made a positive contribution to our financial performance. However, if there are unfavorable changes in revenue, average selling prices, gross margins or operating expenses in one or more of the consolidated companies, then this can result in a negative impact on our consolidated revenue, gross margin and profitability. For unconsolidated, minority-owned joint ventures, these changes can result in a reduction in Equity in Income of Unconsolidated Joint Venture. In 2025 and 2024, these unconsolidated joint ventures contributed gains of $0.8 million and $3.4 million, respectively, to our consolidated financial statements. The last time the companies accounted for under the equity method of accounting contributed a loss was 2019 with a loss of $1.9 million. Unforeseen manufacturing issues and restrictions at the new manufacturing sites could occur. In 2015, the Beijing city government announced its decision to move most of its offices to the Tongzhou district where our original manufacturing facility is currently located. The Beijing city government has moved thousands of government employees into this district. To create room and upgrade the district, the government instructed virtually all existing manufacturing companies, including Tongmei, to relocate all or some of their manufacturing lines. We were instructed to move our gallium arsenide manufacturing lines out of the area. 64 Table of Contents Although the relocation is completed and we are in volume production at the new sites, unforeseen manufacturing issues and restrictions at the new sites could occur. Problems could occur as we add capacity or comply with strict guidelines as customers perform their qualifications. All of this will require us to continue to diligently address the many details that arise at each of our new sites. A failure to properly accomplish this could result in disruption to our production and have a material adverse impact on our revenue, our results of operations and our financial condition. If we fail to meet the product qualification and volume requirements of a customer, we may lose sales to that customer. Our reputation may also be damaged. Any loss of sales could have a material adverse effect on our revenue, our results of operations and our financial condition. The Chinese government has in the past imposed temporary restrictions on manufacturing facilities, such as the restrictions imposed on polluting factories for the 2008 Olympics and the 2014 Asian Pacific Economic Cooperation event. These restrictions included a shutdown of the transportation of materials and power plants to reduce air pollution. To reduce air pollution in Beijing, the Chinese government has sometimes limited the construction of new, or expansion of existing, facilities by manufacturing companies in the Beijing area or required mandatory factory shutdowns. For example, in the first quarter of 2018, over 300 manufacturing companies, including Tongmei, were intermittently shut down by the local government for a total of ten days from February 27 to March 31 due to severe air pollution. If the government applies restrictions to us or requires mandatory factory shutdowns in the future, then such restrictions or shutdowns could have an adverse impact on our results of operations and our financial condition. Our ability to supply current or new orders could be significantly impacted. Customers could then be required to purchase products from our competitors, causing our competitors to take market share from us. In addition, from time to time, the Chinese government issues new regulations, which may require additional actions on our part to comply. On February 27, 2015, the China State Administration of Work Safety updated its list of hazardous substances. The previous list, which was published in 2002, did not restrict the materials that we use in our wafers. The new list added gallium arsenide. As a result of the newly published list, we were required to seek additional permits. If we do not successfully develop new product features and improvements and new products that respond to customer requirements, our ability to generate revenue, obtain new customers, and retain existing customers may suffer. Our success depends on our ability to offer new product features, improved performance characteristics and new products, such as larger diameter substrates, low defect density substrates, thicker or thinner substrates, substrates with extreme surface flatness specifications, substrates that are manufactured with a doped crystal growth process or substrates that incorporate leading technology and other technological advances. This is an ongoing iterative research and development process performed by our China team in collaboration with our product marketing managers. New products must meet customer needs and compete effectively on quality, price and performance. The markets for our products are characterized by rapid technological change, changing customer needs and evolving industry standards. If our competitors introduce products employing new technologies or performance characteristics, our existing products could become obsolete and unmarketable. Over time, we have seen our competitors selling more substrates manufactured using a crystal growth technology similar to ours, which has eroded our technological differentiation. The development of new product features, improved performance characteristics and new products can be a highly complex process, and we may experience delays in developing and introducing them. Any significant delay could cause us to fail to timely introduce and gain market acceptance of new products. Further, the costs involved in researching, developing and engineering new products could be greater than anticipated. If we fail to offer new products or product enhancements or fail to achieve higher quality products, we may not generate sufficient revenue to offset our development costs and other expenses or meet our customers’ requirements. The loss of one or more of our tier one substrate customers would significantly hurt our operating results. From time to time, sales to one or more of our tier one customers individually represent more than 10% of our revenue and if we were to lose a major customer the loss would negatively impact our revenue. Our customers are not obligated to purchase a specified quantity of our products or to provide us with binding forecasts of product purchases. In addition, our customers may reduce, delay or cancel orders. In the past, we have experienced a slowdown in bookings, significant push-outs and cancellation of orders from customers. If we lose a major customer or if a customer cancels, reduces or delays orders, our revenue would decline. In addition, customers that have accounted for significant revenue in the past may not continue to generate revenue for us in any future period. Any loss of customers or any delay in scheduled shipments of our products could cause revenue to fall below our expectations and the expectations of market analysts or investors, causing our stock price to decline. 65 Table of Contents We may not achieve the revenues we expect under our long term supply agreement with our customers. We have entered into long-term supply agreements with customers that include customer prepayments or other advance payments. We are currently in discussions with other customers to form similar agreements. Although these arrangements may provide increased visibility into future demand and cash flows, they do not guarantee future revenue or profitability. Our ability to recognize revenue from such arrangements depends on our ability to satisfy our contractual performance obligations, including delivering products or services in accordance with agreed-upon specifications, quantities, and delivery schedules. In addition, customer prepayments received under these arrangements may result in obligations to provide products or services in future periods. If we are unable to fulfill these obligations, including due to production delays, supply constraints, changes in customer requirements, or other factors, we may be required to provide refunds, credits, or other concessions, which could adversely affect our financial condition and results of operations. In addition, customer demand, market conditions, technology changes, pricing pressures, or other circumstances may change after entering into long-term agreements. If customers reduce, delay, or cancel orders, or if we are unable to convert customer prepayments into recognized revenue as anticipated, our revenue, operating results, and liquidity could be adversely affected. Defects in our products could diminish demand for our products. Our wafer products are complex and may contain defects, including defects resulting from impurities inherent in our raw materials or inconsistencies in our manufacturing processes. We have experienced quality control problems with some of our products, which caused customers to return products to us, reduce orders for our products, or both. If we experience quality control problems, or experience other manufacturing problems, customers may return product for credit, cancel or reduce orders or purchase products from our competitors. We may be unable to maintain or increase sales to our customers and sales of our products could decline. Defects in our products could cause us to incur higher manufacturing costs and suffer product returns and additional service expenses, all of which could adversely impact our operating results. If new products developed by us contain defects when released, our customers may be dissatisfied and we may suffer negative publicity or customer claims against us, lose sales or experience delays in market acceptance of our new products. 66 Table of Contents Demand for our products may decrease if demand for the end-user applications decrease or if manufacturers downstream in our supply chain experience difficulty manufacturing, marketing or selling their products. Our products are used to produce components for electronic and opto-electronic products. Accordingly, demand for our products is subject to the demand for end-user applications, including certain consumer applications, which utilize our products. For example, we have developed an 8-inch gallium arsenide wafer targeting an application in a consumer product, which was scheduled to begin production in 2024. However, we were informed by our customer that its end-user customer cancelled its project. While there may be other end users, this particular cancellation is the loss of a potentially high-volume sales opportunity. Other factors affecting the ability of the manufacturers downstream in our supply chain to introduce and market their products successfully, include: ● worldwide economic and political conditions and their impact on levels of business spending; ● the competition such manufacturers face in their particular industries; ● end of life obsolescence of products containing devices built on our wafers; ● the technical, manufacturing, sales, marketing and management capabilities of such manufacturers; ● the financial and other resources of such manufacturers; and ● the inability of such manufacturers to sell their products if they infringe third‑party intellectual property rights. If demand for the end-user applications for which our products are used decreases, or if manufacturers downstream in our supply chain are unable to develop, market and sell their products, demand for our products will decrease. For example, during 2019 widespread political and economic instability and trade war concerns resulted in a general slowdown and our revenue decreased significantly. Additionally, in the second half of 2016, manufacturers producing and selling passive optical network devices known as EPONs and GPONs experienced a slowdown in demand resulting in surplus inventory on hand. The slowdown persisted until late in 2017. This resulted in a slowdown of sales of our InP substrates used in the PON market. In the second half of 2022, many companies purchased more inventory than needed, in part due to fears of shortages resulting from COVID. This triggered an inventory correction cycle and our revenue declined as customers worked down their inventory level. We expect similar cycles of strong demand followed by lower demand will occur for various InP, GaAs or Ge substrates in the future. Intense competition in the markets for our products could prevent us from increasing revenue and achieving profitability. The markets for our products are intensely competitive. We face competition for our wafer substrate products from other manufacturers of substrates, such as Sumitomo, JX, Freiberger, Umicore, Vital and CCTC, and from companies, such as Qorvo and Skyworks, that are actively considering alternative materials to GaAs and marketing semiconductor devices using these alternative materials. Sumitomo and JX also compete with us in the InP market. If we are unable to compete effectively, our revenue may decrease and we may not maintain profitability. We face many competitors that have a number of significant advantages over us, including: ● greater name recognition and market share in the business; ● more manufacturing experience; ● extensive intellectual property; and ● significantly greater financial, technical and marketing resources. 67 Table of Contents Our competitors could develop new or enhanced products that are more effective than our products. The level and intensity of competition has increased over the past years and we expect competition to continue to increase in the future. Competitive pressures have resulted in reductions in the prices of our products, and continued or increased competition could reduce our market share, require us to further reduce the prices of our products, affect our ability to recover costs and result in reduced gross margins and profitability. In addition, new competitors have and may continue to emerge, such as a company established by a former employee in China that is supplying semi-conducting GaAs wafers to the LED market. Competition from sources such as this could increase, particularly if these competitors are able to obtain large capital investments. Further, recent trade tensions between China and the United States have resulted in a greater determination within China to be self-sufficient and produce more goods domestically. This could result in the formation of new competitors that would compete against us and adversely affect our financial results. The average selling prices of our substrates may decline over relatively short periods, which may reduce our revenue and gross margins. Since the market for our products is characterized by declining average selling prices resulting from various factors, such as increased competition, overcapacity, the introduction of new products and decreased sales of products incorporating our products, the average selling prices for our products may decline over relatively short time periods. We have in the past experienced, and in the future may experience, substantial period-to-period fluctuations in operating results due to declining average selling prices. In certain years, we have experienced an average selling price decline of our substrate selling prices of approximately 5% to 10%, depending on the substrate product. It is possible that the pace of the decline of average selling prices could accelerate beyond these levels for certain products in a commoditizing market. We anticipate that average selling prices may decrease in the future in response to the unstable demand environment, price reductions by competitors, or by other factors, including pricing pressures from significant customers. When our average selling prices decline, our revenue and gross profit decline, unless we are able to sell more products or reduce the cost to manufacture our products. We generally attempt to combat an average selling price decline by improving yields and manufacturing efficiencies and working to reduce the costs of our raw materials and of manufacturing our products. We also need to sell our current products in increasing volumes to offset any decline in their average selling prices, and introduce new products, which we may not be able to do, or do on a timely basis. In order to remain competitive, we must continually improve our processes, work to reduce the cost of manufacturing our products and improve our yields and manufacturing efficiencies. Our efforts may not allow us to keep pace with competitive pricing pressures which could adversely affect our margins. There is no assurance that any changes implemented by us will result in sufficient cost reductions to allow us to reduce the price of our products to remain competitive or improve our gross margins. We have made and may continue to make strategic investments in raw materials suppliers, which may not be successful and may result in the loss of all or part of our investment. We have made direct investments or investments through our subsidiaries in raw material suppliers in China, which provide us with opportunities to gain supplies of key raw materials that are important to our substrate business. These affiliates each have a market beyond that provided by us. We may not have significant influence over every one of these companies and in some we have made only a strategic, minority investment. We may not be successful in achieving the financial, technological or commercial advantage upon which any given investment is premised, and we could end up losing all or part of our investment which would have a negative impact on our results of operations. In the first quarter of 2019, we incurred an impairment charge of $1.1 million for a germanium materials company in China in which we had a 25% ownership interest, writing down our investment to zero value. During the second quarter of 2023, one of our equity investments determined that one of its equity investments was fully impaired, leading to a $754,000 impairment charge in our financial results for the second quarter of 2023. In the fourth quarter of 2023, we divested another equity investment, incurring a net impairment charge of $1.1 million. A significant decline in the selling prices of raw materials began in 2015 and weakened some of these companies and their losses negatively impacted our financial results for several years. Further, the increasing concern and restrictions in China of hazardous chemicals and other hazardous materials could result in orders to shut down permanently, fines or other severe measures. Any such orders directed at one of our joint venture companies could result in impairment charges if the company is forced to close its business, cease operations or incurs fines, or operating losses, which would have a material adverse effect on our financial results. 68 Table of Contents If any of our facilities are damaged by occurrences such as fire, explosion, power outage or natural disaster, we might not be able to manufacture our products. The ongoing operation of our manufacturing and production facilities is critical to our ability to meet demand for our products. If we are not able to use all or a significant portion of our facilities for prolonged periods for any reason, we would not be able to manufacture products for our customers. For example, a fire or explosion caused by our use of combustible chemicals, high furnace temperatures or, in the case of InP, high pressure during our manufacturing processes could render some of our facilities inoperable for an indefinite period of time. Actions outside of our control, such as earthquakes or other natural disasters, could also damage our facilities, rendering them inoperable. If we are unable to operate our facilities and manufacture our products, we would lose customers and revenue and our business would be harmed. On the evening of March 15, 2017, an electrical short-circuit fire occurred at our Beijing manufacturing facility. The electrical power supply supporting 2-inch, 3-inch and 4-inch gallium arsenide and germanium crystal growth was damaged and production in that area was stopped. In addition, a wastewater pipe was damaged resulting in a halt to wafer processing for four days until the pipe could be repaired. We were able to rotate key furnace hardware and use some of the 6-inch capacity for smaller diameter crystal growth production to mitigate the impact of the fire and resume production. If we are unable to recover from a fire or natural disaster, our business and operating results could be materially and adversely affected. Our substrate products have a long qualification cycle that makes it difficult to forecast revenue from new customers or for new products sold to existing customers. New customers typically place orders with us for our substrate products three months to a year or more after our initial contact with them. The sale of our products is subject to our customers’ lengthy internal evaluation and qualification processes. During this time, we may incur substantial expenses and expend selling, marketing and management efforts while the customers evaluate our products. These expenditures may not result in sales of our products. If we do not achieve anticipated sales in a period as expected, we may experience an unplanned shortfall in our revenue. As a result, our operating results would be adversely affected. In addition, if we fail to meet the product qualification requirements of the customer, we may not have another opportunity to sell that product to that customer for many months or even years. In the current competitive climate, the average qualification and sales cycle for our products has lengthened even further and is expected to continue to make it difficult for us to forecast our future sales accurately. We anticipate that sales of any future substrate products will also have lengthy qualification periods and will, therefore, be subject to risks substantially similar to those inherent in the lengthy sales cycles of our current substrate products. The cyclical nature of the semiconductor industry may limit our ability to maintain or increase net sales and operating results during industry downturns. The semiconductor industry is highly cyclical and periodically experiences significant economic downturns characterized by diminished product demand, resulting in production overcapacity and excess inventory in the markets we serve. A downturn can result in lower unit volumes and rapid erosion of average selling prices. The semiconductor industry has experienced significant downturns, often in connection with, or in anticipation of, maturing product cycles of both semiconductor companies’ and their customers’ products or a decline in general economic conditions. This may adversely affect our results of operations and the value of our business. A recent example of a cyclical downcycle took shape in the second half of 2022 and continued into 2024. Early in its history, COVID began to impact supply chains resulting in shortages. As a result, in 2021 and into 2022 almost all companies purchased more inventory than they needed as a safety precaution. In the second half of 2022 companies began to realize they were holding too much inventory and entered into the “inventory correction” period. Our consolidated revenue had reached $39.7 million in the first quarter of 2022. In the third quarter of 2023, our revenue had declined to $17.4 million. Our continuing business depends in significant part upon manufacturers of electronic and opto-electronic compound semiconductor devices, as well as the current and anticipated market demand for these devices and products using these devices. As a supplier to the semiconductor industry, we are subject to the business cycles that characterize the industry. The timing, length and volatility of these cycles are difficult to predict. The compound semiconductor industry has historically been cyclical due to sudden changes in demand, the amount of manufacturing capacity and changes in the technology employed in compound semiconductors. The rate of changes in demand, including end demand, is high, and the effect of these changes upon us occurs quickly, exacerbating the volatility of these cycles. These changes have affected the timing and amounts of customers’ purchases and investments in new technology. These industry cycles create pressure on our revenue, gross margin and net income. 69 Table of Contents Our industry has in the past experienced periods of oversupply and that has resulted in significantly reduced prices for compound semiconductor devices and components, including our products, both as a result of general economic changes and overcapacity. Oversupply causes greater price competition and can cause our revenue, gross margins and net income to decline. During periods of weak demand, customers typically reduce purchases, delay delivery of products and/or cancel orders for our products. Order cancellations, reductions in order size or delays in orders could occur and would materially adversely affect our business and results of operations. Actions to reduce our costs may be insufficient to align our structure with prevailing business conditions. We may be required to undertake additional cost-cutting measures, and may be unable to invest in marketing, research and development and engineering at the levels we believe are necessary to maintain our competitive position. Our failure to make these investments could seriously harm our business. A significant portion of our operating expense and manufacturing costs are relatively fixed. If revenue for a particular quarter is lower than we expect, we likely will be unable to proportionately reduce our operating expenses or fixed manufacturing costs for that quarter, which would harm our operating results. We purchase critical raw materials and parts for our equipment from single or limited sources, and could lose sales if these sources fail to fill our needs. We depend on a limited number of suppliers for certain raw materials, components and equipment used in manufacturing our products, including key materials such as quartz tubing, and polishing solutions. We generally purchase these materials through standard purchase orders and not pursuant to long-term supply contracts, and no supplier guarantees supply of raw materials or equipment to us. If we lose any of our key suppliers, our manufacturing efforts could be significantly hampered and we could be prevented from timely producing and delivering products to our customers. We have experienced delays obtaining critical raw materials and spare parts, including gallium, and we could experience such delays again in the future due to shortages of materials or for other reasons. Delays in receiving equipment or materials could result in higher costs and cause us to delay or reduce production of our products. If we have to delay or reduce production, we could fail to meet customer delivery schedules and our revenue and operating results could suffer. We may not be able to identify or form additional complementary raw material joint ventures. We might invest in additional joint venture companies in order to remain competitive in our marketplace and ensure a supply of critical raw materials. However, we may not be able to identify additional complementary joint venture opportunities or, even once opportunities are identified, we may not be able to reach agreement on the terms of the business venture with the other investment partners. Further, geopolitical tensions and trade wars could result in government agencies blocking such new joint ventures. New joint ventures could require cash investments or cause us to incur additional liabilities or other expenses, any of which could adversely affect our financial condition and operating results. The financial condition of our customers may affect their ability to pay amounts owed to us. Some of our customers may be undercapitalized and cope with cash flow issues. Because of competitive market conditions, we may grant our customers extended payment terms when selling products to them. Subsequent to our fulfilling an order, some customers have been unable to make payments when due, reducing our cash balances and causing us to incur charges to allow for a possibility that some accounts might not be paid. In the past, we have had some customers file for bankruptcy. The uncertainty in current economic trends or changes in the domestic, global, political and economic environment may also affect our customers’ ability to pay. If our customers do not pay amounts owed to us then we will incur charges that would reduce our earnings. We depend on the continuing efforts of our senior management team and other key personnel. If we lose members of our senior management team or other key personnel, or are unable to successfully recruit and train qualified personnel, our ability to manufacture and sell our products could be harmed. Our future success depends on the continuing services of members of our senior management team and other key personnel. Our industry is characterized by high demand and intense competition for talent, and the turnover rate can be high. We compete for qualified management and other personnel with other specialty material companies and semiconductor companies. Our employees could leave with little or no prior notice and would be free to work for a competitor. If one or more of our senior executives or other key personnel were unable or unwilling to continue in their present positions, we may not be able to replace them easily or at all, and other senior management may be required to divert attention from other aspects of the business. The loss of any of these individuals or our ability to attract or retain qualified personnel could adversely affect our business. 70 Table of Contents Our results of operations may suffer if we do not effectively manage our inventory. We must manage our inventory of raw materials, work in process and finished goods effectively to meet changing customer requirements, while keeping inventory costs down and improving gross margins. Although we seek to maintain sufficient inventory levels of certain materials to guard against interruptions in supply and to meet our near term needs, we may experience shortages of certain key materials. Alternatively, a sudden decline in demand could result in holding too much inventory which occurred in the second half of 2022. Some of our products and supplies have in the past, and may in the future, become obsolete while in inventory due to changing customer specifications, or become excess inventory due to decreased demand for our products and an inability to sell the inventory within a foreseeable period. This would result in charges that reduce our gross profit and gross margin. Furthermore, if market prices drop below the prices at which we value inventory, we would need to take a charge for a reduction in inventory values in accordance with the lower of cost or net realizable value valuation rule. We have in the past had to take inventory valuation and impairment charges. Any future unexpected changes in demand or increases in costs of production that cause us to take additional charges for un-saleable, obsolete or excess inventory, or to reduce inventory values, would adversely affect our results of operations. The effect of terrorist threats and actions on the general economy could decrease our revenue. Countries such as the United States and China continue to be on alert for terrorist activity. The potential near and long-term impact terrorist activities may have in regards to our suppliers, customers and markets for our products and the economy is uncertain. There may be embargos of ports or products, or destruction of shipments or our facilities, or attacks that affect our personnel. There may be other potentially adverse effects on our operating results due to significant events that we cannot foresee. Since we perform all of our manufacturing operations in China, terrorist activity or threats against U.S. owned enterprises are a particular concern to us. III. Risks Related to International Aspects of Our Business Escalating and volatile trade tariffs, import restrictions, export restrictions, Chinese regulations or other trade barriers may materially harm our business. On February 4, 2025, China added indium phosphide substrates to its export control list. As a result, the three wafer substrate product families manufactured by Tongmei all require permits from China’s Ministry of Commerce before they can be exported from China. InP export permits represent the most significant challenge we currently face. The portal to apply for exports of indium phosphide from China opened in March and we immediately began to submit our applications. On June 11, 2025, Tongmei was informed that it had satisfied the applicable requirements for a permit to export indium phosphide and received its initial export permits from the Ministry of Commerce of the People’s Republic of China to resume shipping indium phosphide substrates to certain customers in Europe and Japan. While we have received some permits as of the date of this report, we cannot predict when a permit application will be reviewed and approved. On December 27, 2025, the Standing Committee of the National People’s Congress of China (“NPC”) enacted substantial revisions to the Foreign Trade Law of the People’s Republic of China, effective March 1, 2026 (the “Foreign Trade Law”). The revisions to the Foreign Trade Law provide, among other things, enhanced power vested in governmental agencies to prohibit or restrict the import or export of goods and technologies for a variety of reasons set forth in Article 18 of the Foreign Trade Law, including, but not limited to, (i) safeguarding national security, (ii) where there is a domestic shortage of supply or to protect potentially depleted natural resources, (iii) in order to establish or accelerate the establishment of specific domestic industries, and (iv) other circumstances where it is necessary to prohibit or restrict the import or export of relevant goods or technologies, or take other necessary measures. The revisions also include a chapter on intellectual property introducing new trade sanctions for the infringement of intellectual property rights when such infringement endangers the order of foreign trade and targets specific licensing practices that prohibit the challenge of a license’s validity or portfolio licensing bundling. The specific prohibitions and restrictions on the import and export of goods and technologies are delegated to the Ministry of Commerce of the People’s Republic of China, among other agencies. As mentioned above, the three wafer substrate product families manufactured by Tongmei all require permits from the Ministry of Commerce before they can be exported from China. Consequently, we do not believe that the revisions will have any additional material adverse effects on our wafer substrate products beyond the current restrictions and licensing requirement. However, with the Foreign Trade Law’s enhanced power over import and export prohibitions and restrictions, no assurances can be given that additional restrictions will not be imposed in the future. The fluidity of the export permit requirements presents an ongoing lack of certainty for us and for our customers. To our knowledge, indium phosphide is rarely used in military applications and we can reasonably expect that export permits to ship our indium phosphide substrates to the U.S. will eventually be granted. But the timing for receiving permits remains uncertain, unclear and beyond our control. Further, we consider the effects of geopolitical uncertainties between the United States and the People's Republic of China to be a risk. Obtaining export permits for the sale of our indium phosphide substrates on a timely basis may result in a mismatch between our receipt of purchase orders for indium phosphide substrates and the recognition of revenue under U.S. GAAP which may have a material adverse effect on our business, financial condition, and results of operations. We are actively monitoring and following up on the status of our applications. 71 Table of Contents In September 2018, the United States announced a list of thousands of categories of goods that became subject to Section 301 tariffs when imported into the United States from China. This pronouncement imposed tariffs on wafer substrates we imported into the United States. The initial tariff rate was 25%. On July 3, 2023, China announced new export control regulations on materials including gallium and germanium and compounds of these materials, effective as of August 1, 2023. Materials that could be used in military applications, specifically including weapons of mass destruction, were the primary focus. This required Tongmei to seek permits from the applicable Chinese authorities to export gallium arsenide and germanium substrates. Since that time, a general escalation has been underway with further increases to the tariffs from the US and additional export controls from China. The escalating requirements resulted in a new layer of administration within our company. Each order needs the customer to certify in writing that our wafer substrates will not be used in military applications and must state the end use of our products. This is a labor intensive process and has extended the cycle time in order fulfillment. To ensure compliance in trade matters we have consulted with legal experts and incurred additional legal costs. The rapid pace of change and new regulations in trade matters results in more internal administrative review and costs. In late 2024 and early 2025, a new round of trade restrictions was announced by China and the United States. On December 3, 2024 China issued further rules restricting exports of materials that can typically be used in military applications including antimony, gallium, germanium and other superhard materials. The effective date was December 3, 2024, the same day as the announcement itself. Reciprocally, the United States increased tariffs on many items from China from 25% to 50%, effective January 1, 2025. On February 1, 2025, the United States again further increased the tariff on imports of many products from China, including our wafer substrates, to 60%. On March 4, 2025, the United States further increased the tariff on imports of many products, including our wafer substrates, to 70%. On February 20, 2026, the U.S. Supreme Court invalidated many of the global tariffs previously imposed under the International Emergency Economic Powers Act of 1977 (the "IEEPA") and the U.S. Customs and Border Protection subsequently announced that IEEPA-based tariff provisions would be terminated effective February 24, 2026. However, tariffs imposed under other authorities, including Section 232 of the Trade Expansion Act of 1962 and Section 301 of the Trade Act of 1974, remain in effect, and the U.S. government has indicted that it may pursue additional or replacement tariffs under alternative legal authorities, including temporary measures under Section 122 of the Trade Act of 1974. If maintained, these announced new tariffs, as well as related measures that could be taken by other countries and the potential escalation of trade disputes, could affect our business and results of operations. Indium phosphide substrates are the primary revenue generator derived from imports into the U.S. This revenue has been impacted by additional tariffs imposed by the United States and by export controls implemented by China. In 2024, 8% of our total worldwide revenue was from sales in North America, primarily in the U.S.; however, in 2025, only approximately 2% of our revenue was generated by sales to customers in North America. We have little or no germanium imports into the U.S. and historically a relatively small value of imports of gallium arsenide wafers into the U.S. While Tongmei has generally received the required permits for exports to countries in Asia and Europe, our U.S. gallium arsenide customers are considered “dual use” customers: in addition to commercial applications they have significant levels of military involvement. As such, no permits for gallium arsenide to the U.S. have yet been approved. 72 Table of Contents All of our wafer substrates are manufactured in China and in the years 2025, 2024 and 2023, approximately 2%, 8% and 10% of our revenue, respectively, were generated by sales to customers in North America, primarily in the U.S. In the years 2025, 2024 and 2023, we paid approximately $0.3 million, $1.0 million and $1.0 million, respectively, in tariffs. The future impact of tariffs and trade wars is uncertain. We may be required to raise prices, which could result in the loss of customers and our business, financial condition and results of operations may be materially harmed. Additionally, it is possible that our business could be adversely impacted by further retaliatory trade measures taken by China or other countries in response to existing or future tariffs. Such measures could cause us to raise prices or make changes to our operations, which could materially harm our business, financial condition and results of operations. The economic and political conditions between China and the United States, in our view, create an unstable business environment. Reciprocal trade restrictions have resulted in a greater determination to be self-sufficient and produce more goods domestically. Both governments appear to be encouraging and supporting the founding of new companies, the addition of new products in existing companies and more vertical integration within companies. The complexity and uncertainty of trade tensions has caused some customers and prospective customers in each county to adopt sourcing policies that block purchases from suppliers in the other county. Further, the continued threats of tariffs and other trade restrictions could have a generally disruptive impact on the global economy and, therefore, negatively impact our sales. We continue to monitor developments closely, including pending legal challenges to certain tariff authorities, updated guidance from regulators, retaliatory measures, resolution of trade agreements and ongoing negotiations with additional trade partners. In addition, ongoing uncertainty regarding the mechanisms, timing and amount of any refunds or other relief relating to previously paid duties may affect our cash flows and results in future periods. We cannot predict the scope, timing or ultimate impact of these developments on our business. The trade and political tensions between China and the U.S. remain high and controls on exports and tariffs are changing and fluid. There can be no assurances that Tongmei will receive China permits to export our wafer substrates or that China will not adopt additional export control regulations that affect our business, financial condition and results of operations. Reciprocally, there can be no assurance that the U.S. will allow products to be imported into the U.S. from China or what the tariff charge rate might be. Further, a volatile global trade environment increases the likelihood of supply chain disruption. Trade barriers, political conflict, and uncertainty surrounding tariffs can lead to logistical challenges such as shipping delays, port congestion, container shortages, and other transportation bottlenecks. These disruptions may hinder our ability to meet customer demand on a timely basis. Consequently, prolonged trade tensions or supply chain disturbances could significantly increase our operating costs which may require us to consider alternative manufacturing options. There is no guarantee that we can secure alternative manufacturing facilities to meet customer demand of our products. Any failure to manage these international trade and supply chain risks could materially and adversely affect our business, financial condition, and results of operations. Changes in China’s political, social, regulatory or economic environments may affect our financial performance. Our financial performance may be affected by changes in China’s political, social, regulatory or economic environments. The role of the Chinese central and local governments in the Chinese economy is significant. The Beijing municipal government’s decision to move to the Tongzhou district, the original location of our China company, resulted in the city instructing virtually all existing manufacturing companies, including AXT, to relocate all or some of their manufacturing lines. We were instructed to move our gallium arsenide manufacturing line out of the area. Chinese policies toward hazardous materials, including arsenic, environmental controls, air pollution, economic liberalization, laws and policies affecting technology companies, foreign investment, currency exchange rates, taxation structure and other matters could change, resulting in greater restrictions on our ability to do business and operate our manufacturing facilities in China. We have observed a growing fluidity and tightening of regulations concerning hazardous materials, other environmental controls and air pollution. The Chinese government could revoke, terminate or suspend our operating licenses for reasons related to environmental control over the use of hazardous materials, air pollution, labor complaints, national security and similar reasons without compensation to us. Further, the central government encourages employees to report to the appropriate regulatory agencies possible safety or environmental violations, but there may not be actual violations. In days of severe air pollution the government has ordered manufacturing companies to stop all production. For example, in the first quarter of 2018, from February 27 to March 31, over 300 manufacturing companies, including us, were again intermittently shut down by the local government for a total of ten days due to severe air pollution. Our shipments were delayed and our revenue for the quarter was negatively impacted. We expect that mandatory factory shutdowns may occur in the future. Any failure on our part to comply with governmental regulations could result in the loss of our ability to manufacture our products. Further, any imposition of surcharges or any increase in Chinese tax rates or reduction or elimination of Chinese tax benefits could hurt our financial results. 73 Table of Contents The Chinese central government is increasingly aware of air pollution and other forms of environmental pollution and their reform efforts can impact our manufacturing, including intermittent mandatory shutdowns. The Chinese central government is demonstrating strong leadership to improve air quality and reduce environmental pollution. These efforts have impacted manufacturing companies through mandatory shutdowns, increased inspections and regulatory reforms. In the fourth quarter of 2017, many manufacturing companies in the greater Beijing area, including Tongmei, were instructed by the local government to cease most manufacturing for several days until the air quality improved. In the first quarter of 2018, from February 27 to March 31 over 300 manufacturing companies, including Tongmei, were again intermittently shut down by the local government for a total of ten days, or 30 percent of the remaining calendar days, due to severe air pollution. Our shipments were delayed and our revenue for the quarter was negatively impacted. We expect that mandatory factory shutdowns may occur in the future. If the frequency of such shutdowns increases, especially at the end of a quarter, or if the total number of days of shutdowns prevents us from producing enough wafers to ship, then these shutdowns will have a material adverse effect on our manufacturing output, revenue and factory utilization. Each of our raw material supply chain companies could also be impacted by environmental related orders from the central government. Although we are a Delaware corporation and are neither a PRC operating company nor do we conduct our operations in China through the use of VIEs, in the event we inadvertently concluded that we do not require any permissions or approvals from the CSRC or other PRC central government authorities to complete a public offering of securities in the U.S. or applicable laws, regulations, or interpretations change, we may be required to obtain such permissions or approvals to complete such a public offering of securities. We are a Delaware corporation and are neither a PRC operating company nor do we conduct our operations in China through the use of VIEs. All of our products are manufactured in the PRC by our PRC subsidiaries and PRC joint ventures. We believe that we do not require any permissions or approvals from the CSRC or other PRC central government authorities to complete a public offering of securities in the U.S. because we are a Delaware corporation with our principal corporate office in Fremont, California and the PRC laws and regulations that govern the listing of securities on a U.S. securities exchange apply to PRC companies. However, in the event that we inadvertently concluded that such permission or approvals are not required or applicable laws, regulations, or interpretations change and we are required to obtain such permissions or approvals in the future and we fail to obtain such permissions or approvals, then we may not be able to complete a public offering of securities in the U.S. We may also be pressured to delist our securities, which would force the holders to sell these securities and could result in a material adverse effect on the value of these securities. We may face sanctions by the CSRC or other PRC central government authorities or pressure from the PRC government in various business matters for failure to obtain such permissions or approvals. These sanctions or pressure may include fines and penalties on our operations in China, limitations on our operating privileges in China, delays in or restrictions on the repatriation of the proceeds from a public offering of securities in the U.S. into the PRC, restrictions on or prohibition of the payments or remittance of dividends by our subsidiaries in China, or other actions that could have a material and adverse effect on our business, financial condition, results of operations, reputation and prospects, as well as the trading price of our common stock. The PRC central government may intervene in or influence our PRC operations at any time and the rules and regulations in China can change quickly with little advance notice. The businesses of our PRC subsidiaries and PRC joint ventures are subject to complex and rapidly evolving laws and regulations in the PRC, which can change quickly with little advance notice. The PRC central government is a single party form of government with virtually unlimited authority and power to intervene in or influence commercial operations in China. In the past, we have experienced such intervention or influence by a change in the rules and regulations when we were instructed by the Beijing municipal government to relocate our gallium arsenide manufacturing facility from Beijing. A more recent example is the imposition of export controls. We expect that such intervention or change in the rules and regulations in China could occur in the future. In the ordinary course of business, our PRC subsidiaries and PRC joint ventures require permits and licenses to operate in the PRC. Such permits and licenses include permits to use hazardous materials in manufacturing operations. From time to time, the PRC government issues new regulations, which may require additional actions on the part of our PRC subsidiaries and PRC joint ventures to comply. For example, on February 27, 2015, the China State Administration of Work Safety updated its list of hazardous substances. The previous list, which was published in 2002, did not restrict the materials that we use in our wafers. The new list added gallium arsenide. As a result of the newly published list, we were required to seek additional permits. Any such intervention or influence or change in the rules and regulations in China could result in a material change in our PRC operations and/or the value of our common stock. 74 Table of Contents Uncertainty regarding the United States’ foreign policy, particularly with regards to China, could disrupt our business. We manufacture our substrates in China and, in the year ended December 31, 2025, approximately 98% of our sales were to customers located outside the United States. Further, we have partial ownership of raw material companies in China as part of our supply chain. The United States’ current foreign policy has created uncertainty and caution in the international business community, resulting in disruptions in manufacturing, import/export, trade tariffs, sales, investments and other business activity. Such disruptions have had an adverse impact on our financial performance and could continue in the future. Epidemic diseases, other contagious diseases or the perception of their effects, may affect our business operations and financial performance. Outbreaks of epidemic, pandemic, or contagious diseases, such as the COVID-19 pandemic could result in business disruptions and impact our operations and financial performance. The outbreak of COVID triggered references to the SARS outbreak, which occurred in 2003 and affected our business operations. Any severe occurrence of an outbreak of a contagious disease such as COVID-19, SARS, Avian Flu or Ebola may cause us or the government to temporarily close our manufacturing operations in China. In January 2020, virtually all companies in China were ordered to remain closed after the traditional Lunar New Year holiday ended, including our subsidiaries in China. If there is a renewed surge of the COVID-19 pandemic or of other contagious diseases in cities in which our PRC subsidiaries and PRC joint ventures are located, the Chinese government may require these companies to close again. If one or more of our key suppliers is required to close for an extended period, we might not have enough raw material inventories to continue manufacturing operations. In addition, during COVID-19, travel restrictions between China and the U.S. were disrupted and this impacted our efficiency. In the future, if our manufacturing operations were closed for a significant period or we experience difficulty in shipping our products, we could lose revenue and market share, which would depress our financial performance and could be difficult to recapture. If one of our key customers is required to close for an extended period, this may delay the placement of new orders. Any significant outbreak of epidemic, pandemic, or contagious diseases could result in a widespread health crisis that could adversely affect the economies and financial markets of many countries, which could have a material adverse effect on our business, financial condition, results of operations, or cash flows. As a result, our revenue would decline. Financial market volatility and adverse changes in the domestic, global, political and economic environment could have a significant adverse impact on our business, financial condition and operating results. We are subject to the risks arising from adverse changes and uncertainty in domestic and global economies and policies. Uncertain global economic and political conditions or low or negative growth in China, Europe or the United States, along with volatility in the financial markets and U.S. financial system, increasing national debt and fiscal concerns in various regions and the adoption and availability of fiscal and monetary stimulus measures, pose challenges to our industry. Currently China’s economy is slowing and this could impact our financial performance. In addition, tariffs, trade restrictions, trade wars, high levels of inflation, high interest rates, the Russian invasion of Ukraine, the Middle East conflict, the Red Sea shipping disruptions, Brexit, heightened tensions between the U.S. and China, and U.S. bank failures in 2023, among other factors, are creating an unstable environment and can disrupt or restrict commerce. Although we remain well-capitalized, the cost and availability of funds may be adversely affected by illiquid credit markets. Volatility in U.S. and international markets and economies may adversely affect our liquidity, financial condition and profitability. Another severe or prolonged economic downturn could result in a variety of risks to our business, including: ● inventory corrections; ● increased volatility in our stock price; ● increased volatility in foreign currency exchange rates; ● delays in, or curtailment of, purchasing decisions by our customers or potential customers; ● increased credit risk associated with our customers or potential customers, particularly those that may operate in industries most affected by an economic downturn; and ● impairment of our tangible or intangible assets. 75 Table of Contents A recent example of economic volatility took shape in the second half of 2022 and continued into 2024. Early in its history, COVID-19 began to impact supply chains resulting in shortages. As a result, in 2021 and into 2022 almost all companies purchased more inventory than needed as a safety net. In the second half of 2022 companies began to realize they had too much inventory and entered into the “inventory correction” period. Our consolidated revenue had reached $39.7 million in the first quarter of 2022. In the third quarter of 2023 our revenue had declined to $17.4 million. In the fourth quarter of 2018 and continuing in 2019, we experienced delays in customer purchasing decisions and disruptions in a normal volume of customer orders that we believe were in part due to the uncertainties in the global economy, resulting in an adverse impact on consumer spending. During challenging and uncertain economic times and in tight credit markets, many customers delay or reduce technology purchases. Should similar events occur again, our business and operating results could be significantly and adversely affected. The PRC central government may also exert more control over offerings conducted overseas and/or foreign investment in China-based issuers, which could result in a material change in our operations and/or the value of our common stock. The PRC central government may also exert more control over offerings conducted overseas and/or foreign investment in China-based issuers, which could result in a material change in our operations and/or the value of our common stock. The PRC central government may also seek to significantly limit or completely hinder our ability to offer or continue to offer our securities to investors and cause the value of such securities to significantly decline or be worthless. Our international operations are exposed to potential adverse tax consequence in China. Our international operations create a risk of potential adverse tax consequences. Taxes on income in our China-based companies are dependent upon acceptance of our operational practices and intercompany transfer pricing by local tax authorities as being on an arm's length basis. Due to inconsistencies among taxing authorities in application of the arm’s length standard, transfer pricing challenges by tax authorities could, if successful, materially increase our consolidated income tax expense. We are subject to tax audits in China and an audit could result in the assessment of additional income tax against us. This could have a material adverse effect on our operating results or cash flows in the period or periods for which that determination is made and could result in increases to our overall tax expense in subsequent periods. Various taxing agencies in China are increasingly focused on tax reform and other legislative action to increase tax revenue. In addition to risks regarding income tax we have in the past been retroactively assessed value added taxes (“VAT” or “sales tax”) and such VAT assessments could occur again in the future. Dividends from within our corporate structure are subject to PRC withholding tax and SAFE approval. Occasionally, one of our PRC subsidiaries or PRC raw material joint ventures declares and pays a dividend. These dividends generally occur when the PRC joint venture declares a dividend for all of its shareholders. We have no current intentions to distribute to our investors earnings under our corporate structure. Dividends paid to the Company are subject to a 10% PRC withholding tax. The Company is required to obtain approval from the State Administration of Foreign Exchange (“SAFE”) to transfer funds in or out of the PRC. SAFE requires a valid agreement to approve the transfers, which are processed through a bank. Other than PRC foreign exchange restrictions, the Company is not subject to any PRC restrictions and limitations on its ability to distribute earnings from its businesses. If SAFE approval is denied the dividend payable to the Company would be owed but would not be paid. Our PRC subsidiaries and PRC joint ventures are subject to data security oversight. Our PRC subsidiaries and PRC joint ventures are subject to oversight by the Cyberspace Administration of China (the “CAC”) regarding data security. Except for routine personal information necessary to process payroll and other benefits and emergency contact information, our PRC subsidiaries and PRC joint ventures do not collect or maintain personal information. We believe our PRC subsidiaries and PRC joint ventures are in material compliance with the regulations or policies that have been issued by the CAC. We do not believe AXT, Inc. is subject to oversight by the CAC regarding data security. AXT, Inc. is neither a PRC operating company nor do we conduct our operations in China through the use of VIEs. However, cybersecurity is increasingly a focus of the central government and we may be required to change our existing practices in data privacy and cybersecurity matters at substantial costs, which could cause us to make changes to our operations that could materially harm our business, financial condition and results of operations. 76 Table of Contents We derive a significant portion of our revenue from international sales, and our ability to sustain and increase our international sales involves significant risks. Approximately 99% of our revenue is from international sales. We expect that sales to customers outside the United States, particularly sales to customers in Japan, Taiwan, Europe and China, will continue to represent a significant portion of our revenue. Therefore, our revenue growth depends significantly on the expansion of our international sales and operations. All of our manufacturing facilities and most of our suppliers are also located outside the United States. Managing our overseas operations presents challenges, including export permit requirements, periodic regional economic downturns, trade balance issues, threats of trade wars, varying business conditions and demands, political instability, variations in enforcement of intellectual property and contract rights in different jurisdictions, differences in the ability to develop relationships with suppliers and other local businesses, changes in U.S. and international laws and regulations, including import tariffs, fluctuations in interest and currency exchange rates, the ability to provide sufficient levels of technical support in different locations, cultural differences and perceptions of U.S. companies, shipping delays and terrorist acts or acts of war, natural disasters and epidemics or pandemics, such as COVID-19, among other risks. Many of these challenges are present in China, which represents a large potential market for semiconductor devices. Global uncertainties with respect to: (i) economic growth rates in various countries; (ii) sustainability of demand for electronic products; (iii) capital spending by semiconductor manufacturers; (iv) price weakness for certain semiconductor devices; (v) changing and tightening environmental regulations; (vi) political instability in regions where we have operations and (vii) trade wars may also affect our business, financial condition and results of operations. Our dependence on international sales involves a number of risks, including: ● changes in tariffs, import restrictions, export restrictions, or other trade barriers; ● unexpected changes in regulatory requirements; ● longer periods to collect accounts receivable; ● foreign exchange rate fluctuations; ● changes in export license requirements; ● political and economic instability; and ● unexpected changes in diplomatic and trade relationships. Most of our sales are denominated in U.S. dollars, except for sales to our Chinese customers which are denominated in renminbi and our Japanese customers which are denominated in Japanese yen. We also have some small sales denominated in Euro. Increases in the value of the U.S. dollar could increase the price of our products in non-U.S. markets and make our products more expensive than competitors’ products in these markets. We are subject to foreign exchange gains and losses that may materially impact our condensed consolidated statements of operations. We are subject to foreign exchange gains and losses that may materially impact our condensed consolidated statements of operations. For example, in 2025, 2024 and 2023, we incurred foreign exchange losses of $74,000 and foreign exchange gains of $91,000 and $169,000, respectively. 77 Table of Contents The functional currency of our companies in China is the Chinese renminbi, the local currency. We can incur foreign exchange gains or losses when we pay dollars to one of our China-based companies or a third-party supplier in China. Similarly, if a company in China pays renminbi into one of our bank accounts transacting in dollars the renminbi will be converted to dollars and we can incur a foreign exchange gain or loss. Hedging renminbi will be considered in the future but it is complicated by the number of companies involved, the diversity of transactions and restrictions imposed by the banking system in China. Sales to Japanese customers are denominated in Japanese yen. This subjects us to fluctuations in the exchange rates between the U.S. dollar and the Japanese yen and can result in foreign exchange gains and losses. This has been problematic in the past and, therefore, we instituted a foreign currency hedging program dealing with yen which has historically mitigated the gains and losses caused by fluctuations in the exchange rates. Joint venture raw material companies in China bring certain risks. Since our consolidated subsidiaries and all of our joint venture raw material companies operate in China, their activities could subject us to a number of risks associated with conducting operations internationally, including: ● import and export restrictions; ● unexpected changes in regulatory requirements that may limit our ability to manufacture, export the products of these companies, sell into particular jurisdictions or impose multiple conflicting tax laws and regulations; ● the imposition of tariffs, trade barriers and duties; ● difficulties in managing geographically disparate operations; ● difficulties in enforcing agreements through non-U.S. legal systems; ● political and economic instability, civil unrest or war; ● terrorist activities that impact international commerce; ● difficulties in protecting our intellectual property rights, particularly in countries where the laws and practices do not protect proprietary rights to as great an extent as do the laws and practices of the United States; ● new or changing laws and policies affecting economic liberalization, foreign investment, currency convertibility or exchange rates, taxation or employment; ● new or changing PRC regulations and policies regarding data security and oversight by the CAC of our consolidated subsidiaries and all of our joint venture raw material companies; and ● nationalization of foreign‑owned assets, including intellectual property. If China places restrictions on freight and transportation routes and on ports of entry and departure this could result in shipping delays or increased costs for shipping. In August 2015, there was an explosion at the Port of Tianjin, China. As a result of this incident the government placed restrictions on importing certain materials and on freight routes used to transport these materials. We experienced some modest disruption from these restrictions. If the government were to place additional restrictions on the transportation of materials, then our ability to transport our raw materials or products could be limited and result in manufacturing delays or bottlenecks at shipping ports, affecting our ability to deliver products to our customers. During periods of such restrictions, we may increase our stock of critical materials (such as arsenic, gallium and other items) for use during the period that these restrictions are likely to last, which will increase our use of cash and increase our inventory level. Any of these restrictions could materially and adversely impact our results of operations and our financial condition. 78 Table of Contents Our operating results depend in large part on continued customer acceptance of our substrate products manufactured in China and continued improvements in product quality. We manufacture all of our products in China, and source most of our raw materials in China. We have in the past experienced quality problems with our China manufactured products. Our previous quality problems caused us to lose market share to our competitors as some of our customers reduced their orders until our wafer surface quality was as good and as consistent as that offered by our competitors. If we are unable to continue to achieve customer qualifications for our products, or if we are unable to control product quality, customers may not increase purchases of our products, our China facilities will become underutilized, and we will be unable to achieve revenue growth. If there are power shortages in China, we may have to temporarily close our China operations, which would adversely impact our ability to manufacture our products and meet customer orders, and would result in reduced revenue. In the past, China has faced power shortages resulting in power demand outstripping supply in peak periods. Instability in electrical supply has caused sporadic outages among residential and commercial consumers causing the Chinese government to implement tough measures to ease the energy shortage. If further problems with power shortages occur in the future, we may be required to make temporary closures of our operations or of our subsidiary and joint venture raw material companies. We may be unable to manufacture our products and would then be unable to meet customer orders except from finished goods inventory on hand. As a result, our revenue could be adversely impacted, and our relationships with our customers could suffer, impacting our ability to generate future revenue. In addition, if power is shut off at any of our facilities at any time, either voluntarily or as a result of unplanned brownouts, during certain phases of our manufacturing process including our crystal growth phase, the work in process may be ruined and rendered unusable, causing us to incur costs that will not be covered by revenue, and negatively impacting our cost of revenue and gross margins. Although our audit report is prepared by an independent registered public accounting firm who is currently inspected fully by the PCAOB, there is no guarantee that future audit reports will be prepared by an independent registered public accounting firm that is completely inspected by the PCAOB. Our independent registered public accounting firm, BPM, is registered with the PCAOB and is subject to regular inspections by the PCAOB to assess its compliance with the applicable professional standards. Although we have operations in China, a jurisdiction where the PCAOB was, until 2022, unable to conduct inspections without the approval of the Chinese government authorities, our independent registered public accounting firm is currently inspected fully by the PCAOB. Inspections of other independent registered public accounting firms conducted by the PCAOB outside China have at times identified deficiencies in those independent registered public accounting firms’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. The lack of PCAOB inspections of audit work undertaken in China prevented the PCAOB from regularly evaluating independent registered public accounting firms’ audits and their quality control procedures. As a result, to the extent that any component of our independent registered public accounting firm’s work papers is or becomes located in China, such work papers may not be subject to inspection by the PCAOB. As a result, investors would be deprived of such PCAOB inspections, which could result in limitations or restrictions to our access of the U.S. capital markets. While an agreement has been reached among the CSRC, the SEC and the PCAOB regarding the inspection of PCAOB-independent registered public accounting firms in China, there can be no assurance that we will be able to comply with requirements imposed by U.S. regulators. If the PRC authorities do not fully perform their obligations under the agreement with the PCAOB in the future, or if authorities in the PRC otherwise take positions that render the PCAOB unable to inspect or investigate completely registered public accounting firms headquartered in the PRC and Hong Kong, the PCAOB will make determinations under the HFCA Act. Delisting of our common stock would force holders of our common stock to sell their shares. The market price of our common stock could be adversely affected as a result of anticipated negative impacts of these executive or legislative actions upon, as well as negative investor sentiment towards, companies with operations in China that are listed in the United States, regardless of whether these executive or legislative actions are implemented and regardless of our actual operating performance. 79 Table of Contents IV. Risks Related to Our Financial Results and Capital Structure Management has broad discretion as to the use of our cash balances, including any proceeds from capital raises such as the offering completed in December 2025 for gross proceeds of approximately $100 million and in April 2026 for gross proceeds of approximately $632.5 million, before deducting underwriting discounts and commissions and other offering expenses, and may not use such funds effectively. If we need additional capital, funds may not be available on acceptable terms, or at all. Our management has broad discretion in the application of our cash balances and if we are not able to use this cash effectively, it could adversely affect our business and operations. Our liquidity is affected by many factors, including among others, the expansion of our capacity to meet market demand, in particular to add InP capacity, the acquisition of state-of-the-art equipment, relocating manufacturing lines, other capital expenditures, operating activities, offsetting a business downturn, the effect of exchange rate changes and other factors related to the uncertainties of the industry and global economies. Such matters could draw down our cash reserves, which could adversely affect our financial condition, reduce the value of our common stock and possibly impinge our ability to raise debt and equity funding in the future, at a time when we might need to raise additional cash or elect to raise additional cash. Accordingly, there can be no assurance that events will not require us to seek additional capital or, if required, that such capital would be available on terms acceptable to us, if at all. Certain Investors of Tongmei have a right of redemption as a result of Tongmei’s withdrawal of the IPO application. Pursuant to the Capital Investment Agreements with the Investors, each Investor has the right to require AXT to redeem any or all Tongmei shares held by such Investor at the original purchase price paid by such Investor, without interest, in the event the IPO fails to pass the audit of the Shanghai Stock Exchange, is not approved by the CSRC or Tongmei cancels the IPO application. The aggregate redemption amount is approximately $49 million. On July 8, 2026, the STAR Market accepted Tongmei's withdrawal of its IPO application. Tongmei’s withdrawal of the listing application gives rise to a redemption right: each Investor has the right, but not the obligation, to require the Company or Tongmei to redeem its investment, and the Company or Tongmei has the right, but not the obligation, to redeem each Investor’s investment, in each case for a price equal to the original amount invested, without interest or any other return. Because the redemption price is fixed in RMB, the U.S. dollar amount payable will vary with the RMB/USD exchange rate. Tongmei and the Company are in discussions with each Investor to determine whether it wishes to continue its investment as Tongmei advances toward an application for a Hong Kong Stock Exchange listing, or to have its investment redeemed in whole or in part. The Company has sufficient funds to redeem the Investors' investments in full should full redemption be required. The price of shares of our Common Stock has fluctuated substantially. The price of shares of our common stock has fluctuated substantially. Therefore, some investors who have purchased our common stock at high prices face the risk of losing a significant portion of their original investment if they have to sell at a time when the price of shares of our common stock has declined. For example, during the fourth quarter of 2025, and during the first and second quarter of 2026, the price of our common stock and trading volume have significantly increased compared to prior periods. During this period, we did not make any significant announcements other than our financial condition and results of operations for the three and nine months ended September 30, 2025. Accordingly, the market price of our common stock may fluctuate dramatically and may decline rapidly, irrespective of any developments in our business. In addition, the volatility of our stock price could cause other consequences including causing a short squeeze due to the difference in investment decisions by short sellers of shares of our common stock and buy-and-hold decisions of longer investors. 80 Table of Contents Unpredictable fluctuations in our operating results could disappoint analysts or our investors, which could cause our stock price to decline. We have experienced, and may continue to experience, significant fluctuations in our revenue, gross margins and earnings. Our quarterly and annual revenue and operating results have varied significantly in the past and may vary significantly in the future due to a number of factors, including: ● inventory corrections within the technology sector; ● our ability to develop, manufacture and deliver high quality products in a timely and cost-effective manner; ● unforeseen disruptions at our new sites; ● disruptions in manufacturing if air pollution, or other environmental hazards, or outbreaks of contagious diseases causes the Chinese government to order work stoppages; ● fluctuation of our manufacturing yields; ● decreases in the prices of our or our competitors’ products; ● fluctuations in demand for our products; ● the volume and timing of orders from our customers, and cancellations, push-outs and delays of customer orders once booked; ● decline in general economic conditions or downturns in the industry in which we compete; ● expansion of our manufacturing capacity; ● expansion of our operations in China; ● limited availability and increased cost of raw materials; ● costs incurred in connection with any future acquisitions of businesses or technologies; and ● increases in our expenses, including expenses for research and development. Due to these factors, we believe that period-to-period comparisons of our operating results may not be meaningful indicators of our future performance. A substantial percentage of our operating expenses are fixed, and we may be unable to adjust spending to compensate for an unexpected shortfall in revenue. As a result, any delay in generating revenue could cause our operating results to fall below the expectations of market analysts or investors, which could also cause our stock price to decline. If our operating results and financial performance do not meet the guidance that we have provided to the public, our stock price may decline. We provide public guidance on our expected operating and financial results. Although we believe that this guidance provides our stockholders, investors and analysts with a better understanding of our expectations for the future, such guidance is comprised of forward-looking statements subject to the risks and uncertainties described in this Report and in our other public filings and public statements. Our actual results may not meet the guidance we have provided. If our operating or financial results do not meet our guidance or the expectations of investment analysts, our stock price may decline. 81 Table of Contents Because we do not intend to pay dividends on our common stock, stockholders will benefit from an investment in our stock only if it appreciates in value. We have never declared or paid any cash dividends on our shares of common stock. We currently intend to retain all future earnings, if any, for use in the operations and expansion of the business. As a result, we do not anticipate paying cash dividends in the foreseeable future. In addition, dividends accrue on our outstanding Series A preferred stock at the rate of $0.20 per annum per share of Series A preferred stock. The 883,000 shares of $0.001 par value Series A preferred stock issued and outstanding as of June 30, 2026 and December 31, 2025, valued at $3,532,000, are non-voting and non-convertible preferred stock with a 5.0% cumulative annual dividend rate payable when declared by the Board and a $4 per share liquidation preference over common stock, which must be paid before any distribution is made to common stockholders. Any future determination as to the declaration and payment of cash dividends will be at the discretion of our Board of Directors and will depend on factors the Board of Directors deems relevant, including, among others, our results of operations, financial condition and cash requirements, business prospects, and the terms of our financing arrangements, if any. Accordingly, realization of a gain on stockholders’ investments will depend on the appreciation of the price of our common stock. There is no guarantee that our common stock will appreciate in value. We have adopted certain anti-takeover measures that may make it more difficult for a third party to acquire us and the rights of the holders of common stock may be impaired by the potential issuance of preferred stock. Our Board of Directors has the authority, without stockholder approval, to issue preferred stock with voting, dividend, conversion, liquidation or other rights and this could adversely affect the voting power and equity interest of the holders of common stock. Preferred shares could be issued with the right to more than one vote per common share and could be utilized as a method of discouraging, delaying or preventing a change of control. These steps could be taken without any further vote or action by the common stockholders. The rights of the holders of common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued. The possible negative impact on takeover attempts could adversely affect the price of our common stock. Although we have no present intention to issue any shares of preferred stock or to create any new series of preferred stock, we may issue such shares in the future. Provisions in our restated certificate of incorporation and amended and restated bylaws may have the effect of delaying or preventing a merger, acquisition or change of control, or changes in our management, which could adversely affect the market price of our common stock. The following are some examples of these provisions: ● the division of our Board of Directors into three separate classes, each with three-year terms; ● the right of our Board of Directors to elect a director to fill a space created by a board vacancy or the expansion of the board; ● the ability of our Board of Directors to alter our amended and restated bylaws; and ● the requirement that only our Board of Directors or the holders of at least 10% of our outstanding shares may call a special meeting of our stockholders. Furthermore, because we are incorporated in Delaware, we are subject to the provisions of Section 203 of the Delaware General Corporation Law. These provisions prohibit us from engaging in any business combination with any interested stockholder (a stockholder who owns 15% or more of our outstanding voting stock) for a period of three years following the time that such stockholder became an interested stockholder, unless: ● 662/3% of the shares of voting stock not owned by the interested stockholder approve the merger or combination, or ● the Board of Directors approves the merger or combination or the transaction which resulted in the stockholder becoming an interested stockholder. 82 Table of Contents Our common stock may be delisted from The Nasdaq Global Select Market, which could negatively impact the price of our common stock and our ability to access the capital markets. Our common stock is listed on The Nasdaq Global Select Market. The bid price of our common stock has in the past closed below the $1.00 minimum per share bid price required for continued inclusion on The Nasdaq Global Select Market under Marketplace Rule 5450(a). If the bid price of our common stock remains below $1.00 per share for thirty consecutive business days, we could be subject to delisting from the Nasdaq Global Select Market. In addition, the continued listing of our common stock is contingent upon our compliance with The Nasdaq Global Select Market’s conditions for continued listing. If we fail to meet any Nasdaq listing requirements, including the minimum bid price, satisfaction of minimum financial and other continued listing requirements and standards, including those regarding director independence and independent committee requirements, minimum stockholders’ equity and certain corporate governance requirements, and do not regain compliance, we may be subject to delisting by Nasdaq. Any delisting from The Nasdaq Global Select Market could have an adverse effect on our business and on the trading of our common stock. If a delisting of our common stock were to occur, our common stock would trade in the over-the-counter market and be quoted on a service such as those provided by OTC Markets Group, Inc. Such alternatives are generally considered to be less efficient markets, and our stock price, as well as the liquidity of our common stock, may be adversely impacted as a result. Delisting from The Nasdaq Global Select Market could also have other negative results, including the potential loss of confidence by customers, suppliers and employees, the loss of institutional investor interest and fewer business development opportunities, as well as the loss of liquidity for our stockholders. Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited. As of December 31, 2025, we had U.S. federal net operating loss carryforwards of approximately $50.5 million. We have state net operating loss carryforwards of approximately $138,000, primarily in the state of California, as of December 31, 2025. We do not expect to utilize the loss carryforwards in the next several years unless Tongmei pays a dividend. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income and taxes may be limited. In general, an “ownership change” occurs if there is a cumulative change in our ownership by “5% shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. We might have undergone prior ownership changes, and we may undergo ownership changes in the future, which may result in limitations on our net operating loss carryforwards and other tax attributes. Any such limitations on our ability to use our net operating loss carryforwards and other tax attributes could adversely impact our business, financial condition and results of operations. 83 Table of Contents V. Risks Related to Our Intellectual Property Intellectual property infringement claims may be costly to resolve and could divert management attention. Other companies may hold or obtain patents on inventions or may otherwise claim proprietary rights to technology necessary to our business. The markets in which we compete are comprised of competitors that in some cases hold substantial patent portfolios covering aspects of products that could be similar to ours. We could become subject to claims that we are infringing patent, trademark, copyright or other proprietary rights of others. We may incur expenses to defend ourselves against such claims or enter into cross license agreements that require us to pay royalty payments to resolve such claims. For example, in 2020, we and a competitor entered into a cross license and covenant agreement (the “Cross License Agreement”), which has a term that began on January 1, 2020 and expires on December 31, 2029. We have in the past been involved in lawsuits alleging patent infringement, and could in the future be involved in similar litigation. If we are unable to protect our intellectual property, including our non-patented proprietary process technology, we may lose valuable assets or incur costly litigation. We rely on a combination of patents, copyrights, trademarks, trade secrets and trade secret laws, non-disclosure agreements and other intellectual property protection methods to protect our proprietary technology. We believe that our internal, non-patented proprietary process technology methods, systems and processes are a valuable and critical element of our intellectual property. We must establish and maintain safeguards to avoid the theft of these processes. Our ability to establish and maintain a position of technology leadership also depends on the skills of our development personnel. Despite our efforts to protect our intellectual property, third parties can develop products or processes similar to ours. Our means of protecting our proprietary rights may not be adequate, and our competitors may independently develop similar technology, duplicate our products or design around our patents. We believe that at least two of our competitors ship GaAs substrates produced using a process similar to our VGF process. Our competitors may also develop and patent improvements to the VGF technology upon which we rely, and thus may limit any exclusivity we enjoy by virtue of our patents or trade secrets. It is possible that pending or future United States or foreign patent applications made by us will not be approved, that our issued patents will not protect our intellectual property, or that third parties will challenge our ownership rights or the validity of our patents. In addition, the laws of some foreign countries may not protect our proprietary rights to as great an extent as do the laws of the United States and it may be more difficult to monitor the use of our intellectual property. Our competitors may be able to legitimately ascertain non-patented proprietary technology embedded in our systems. If this occurs, we may not be able to prevent the development of technology substantially similar to ours. We may have to resort to costly litigation to enforce our intellectual property rights, to protect our trade secrets or know-how or to determine their scope, validity or enforceability. Enforcing or defending our proprietary technology is expensive, could cause us to divert resources and may not prove successful. Our protective measures may prove inadequate to protect our proprietary rights, and if we fail to enforce or protect our rights, we could lose valuable assets. 84 Table of Contents VI. Risks Related to Compliance, Environmental Regulations and Other Legal Matters For as long as we are a “smaller reporting company,” we may take advantage of certain scaled disclosures available to Us and will be eligible to rely on reduced disclosure and reporting requirements applicable to smaller reporting companies. We are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. We may continue to qualify as a “smaller reporting company,” which would allow us to continue to take advantage of many of the same exemptions from disclosure requirements, including presenting only the two most recent fiscal years of audited financial statements and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. To the extent we take advantage of such reduced disclosure obligations, it may also make comparison of our financial statements with other public companies difficult or impossible. As of the date of the filing of this report, we are a “well-known seasoned issuer” as defined in Rule 405 of the Securities Act because our non-affiliated common stock public float was above $700 million as of the relevant determination date. If we continue to qualify as a well-known seasoned issuer, we will no longer qualify as a smaller reporting company under the current rules of the SEC. Once we cease to be a smaller reporting company, we will not be eligible to take advantage of the scaled disclosures available to smaller reporting companies and will be subject to increased disclosure and compliance obligations, including accelerated reporting deadlines and associated attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, in addition to the requirement to furnish a report by management on, among other things, the effectiveness of our internal controls over financial reporting. The loss of smaller reporting company status and compliance with such larger company disclosure obligations may increase our legal, accounting and financial compliance costs and cause management and other personnel to divert attention from operational and other business matters to devote additional time to public company reporting requirements. If we, or any of our partially owned supply chain companies, fail to comply with environmental and safety regulations, we may be subject to significant fines or forced to cease our operations. We are subject to federal, state and local environmental and safety laws and regulations in all of our operating locations, including laws and regulations of China, such as laws and regulations related to the development, manufacture and use of our products, the use of hazardous materials, the operation of our facilities, and the use of our real property. These laws and regulations govern the use, storage, discharge and disposal of hazardous materials during manufacturing, research and development, and sales demonstrations. If we, or any of our partially owned supply chain companies, fail to comply with applicable regulations, we could be subject to substantial liability for clean-up efforts, personal injury, fines or suspension or be forced to close or temporarily cease our operations, and/or suspend or terminate the development, manufacture or use of certain of our products, the use of our facilities, or the use of our real property, each of which could have a material adverse effect on our business, financial condition and results of operations. The Chinese central government is demonstrating strong leadership to improve air quality and reduce environmental pollution. The central government encourages employees to report to the appropriate regulatory agencies possible safety or environmental violations but there may not be actual violations. These efforts have impacted manufacturing companies through mandatory shutdowns, increased inspections and regulatory reforms. In the first quarter of 2018, from February 27 to March 31 over 300 manufacturing companies were again intermittently shut down by the local government for a total of ten days, or 30 percent of the remaining calendar days, due to severe air pollution. Our shipments were delayed and our revenue for the quarter was negatively impacted. We expect that mandatory factory shutdowns may occur in the future. If the frequency of such shutdowns increases, especially at the end of a quarter, or if the total number of days of shutdowns prevents us from producing enough wafers to ship, then the shutdowns will have a material adverse effect on our manufacturing output, revenue and factory utilization. We believe the relocation of our gallium arsenide and germanium manufacturing lines mitigates our exposure to factory shutdowns. Each of our raw material supply chain companies could also be impacted by environmental related orders from the central government. 85 Table of Contents In addition, from time to time, the Chinese government issues new regulations, which may require additional actions on our part to comply. For example, on February 27, 2015, the China State Administration of Work Safety updated its list of hazardous substances. The previous list, which was published in 2002, did not restrict the materials that we use in our wafers. The new list added gallium arsenide. As a result of the newly published list, we were required to seek additional permits. We face litigation and legal proceedings which could adversely affect our business, financial condition, results of operations or cash flows. We are subject to lawsuits, investigations and claims in the normal course of our business, which can be expensive, lengthy, and disruptive to normal business operations. As described under the heading in the “Legal Proceedings” section elsewhere in this report, we, along with our Chief Executive Officer, Morris Young, and our Chief Financial Officer, Gary Fischer, are the subject of a complaint alleging violations of federal securities laws. Our current and former directors and certain officers, are also the subject of a derivative lawsuit arising from the same allegations. In the future, we could be subject to other proceedings. This litigation and any other regulatory proceedings or claims may be time consuming, could cause us to incur significant defense costs, are disruptive to our normal business operations, and could damage our reputation or adversely affect our stock price. In the event there is an adverse ruling in any legal or regulatory proceeding or action, we may be required to make payments to third parties that could have a material adverse effect on our business, financial condition, results of operations or cash flows. Further, if we become involved in other class action litigation in the future, it could result in substantial costs and diversion of our management’s attention and resources, thus harming our business. For additional information regarding certain of the matters in which we are involved, see Item 1, “Legal Proceedings,” contained in Part II of this report. We could be subject to suits for personal injuries caused by hazardous materials. In 2005, a complaint was filed against us alleging personal injury, general negligence, intentional tort, wage loss and other damages, including punitive damages, as a result of exposure of plaintiffs to high levels of gallium arsenide in gallium arsenide wafers, and methanol. Other current and/or former employees could bring litigation against us in the future. Although we have in place engineering, administrative and personnel protective equipment programs to address these issues, our ability to expand or continue to operate our present locations could be restricted or we could be required to acquire costly remediation equipment or incur other significant expenses if we were found liable for failure to comply with environmental and safety regulations. Existing or future changes in laws or regulations in the United States or China may require us to incur significant expenditures or liabilities, or may restrict our operations. In addition, our employees could be exposed to chemicals or other hazardous materials at our facilities and we may be subject to lawsuits seeking damages for wrongful death or personal injuries allegedly caused by exposure to chemicals or hazardous materials at our facilities. Litigation is inherently uncertain and while we would expect to defend ourselves vigorously, it is possible that our business, financial condition, results of operations or cash flows could be affected in any particular period by litigation pending and any additional litigation brought against us. In addition, future litigation could divert management’s attention from our business and operations, causing our business and financial results to suffer. We could incur defense or settlement costs in excess of the insurance covering these litigation matters, or that could result in significant judgments against us or cause us to incur costly settlements, in excess of our insurance limits. We are subject to internal control evaluations and attestation requirements of Section 404 of the Sarbanes‑Oxley Act. Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we must include in our Annual Report on Form 10-K a report of management on the effectiveness of our internal control over financial reporting. Ongoing compliance with this requirement is complex, costly and time-consuming and it extends to our companies in China. If: (1) we fail to maintain effective internal control over financial reporting; or (2) our management does not timely assess the adequacy of such internal control, we could be subject to regulatory sanctions and the public’s perception of us may be adversely impacted. We need to continue to improve or implement our systems, procedures and controls. We rely on certain manual processes for data collection and information processing, as do our joint venture companies. If we fail to manage these procedures properly or fail to effectively manage a transition from manual processes to automated processes, our systems and controls may be disrupted. To manage our business effectively, we may need to implement additional management information systems, further develop our operating, administrative, financial and accounting systems and controls, add experienced senior level managers, and maintain close coordination among our executive, engineering, accounting, marketing, sales and operations organizations. 86 Table of Contents
