On May 5, 2022, the company entered into an Agreement and Plan of Merger with MaxLinear, Inc. and Shark Merger Sub, pursuant to which the company agreed to be acquired by MaxLinear. On August 31, 2022, shareholders approved the Transaction. On July 26, 2023, the company and MaxLinear received antitrust approval from the State Administration for Market Regulation of the People's Republic of China. Shortly after receiving SAMR Approval, the company received notice from MaxLinear of its purported termination of the Merger Agreement. The company has filed a claim in the Singapore International Arbitration Centre and is currently pursuing payment of the termination fee of US$160 million ⁶, together with further substantial damages, interest and costs. On February 6, 2025, the board of directors authorized a share repurchase program to repurchase up to US$50 million ⁷ of ADSs over a 6-month period. In the year ended December 31, 2025, the company repurchased approximately 426 thousand ⁸ ADSs for US$24.3 million ⁹ at an average price of US$57.04 ¹⁰ per ADS. On October 28, 2024 and October 27, 2025, the company announced an annual cash dividend of US$2.00 ¹¹ per ADS to be paid in four quarterly installments of US$0.50 ¹² per ADS, paying US$67.3 million ¹³ and US$67.2 million ¹⁴ to shareholders in 2024 and 2025, respectively. In February 2021, the company won a bid with a third party to build an office building in Taipei, Taiwan and executed a property development agreement in May 2021, with property development costs expected to be approximately US$101 million ¹⁵. The company received the construction license in September 2025, and expects to complete construction of the building by the end of 2029, following which it will have approximately 107,870 ¹⁶ square feet of office building space and 10,833 ¹⁷ square feet of land.

Total revenue increased by 10% to US$885.6 million ¹⁸ from US$803.6 million ¹⁹ in the prior year. Gross profit as a percentage of revenue increased by 2.4% points to 48.3% ²⁰ from 45.9% ²¹ in the prior year. Total operating expenses increased by 20.4% to US$334.5 million ²² from US$277.9 million ²³ in the prior year. Operating profit increased by 2.4% to US$93.0 million ²⁴ from US$90.9 million ²⁵ in the prior year. Income tax expense as a percentage of income before income tax decreased to 12.5% ²⁶ from 16.9% ²⁷ in the prior year.

Net income was approximately US$122.6 million ³⁰ for the year ended December 31, 2025 compared to a net income of approximately US$89.2 million ³¹ for the year ended December 31, 2024.

The company is expanding its business into the enterprise market through the development of PCIe (MonTitan controllers and boot drive controllers and solutions) and SATA SSD controllers, driven by the rapid adoption of NAND in enterprise storage driven by AI and other high-performance applications. MonTitan products leverage QLC and TLC NAND flash to target the growing markets for enterprise-class storage solutions, evolving compute requirements and high density warm storage (nearline SSD) in AI infrastructure. In high performance, high capacity QLC SSDs, MonTitan solutions offer significant advantages over HDDs in performance, reduced size and lower power requirements to cloud service providers, hyperscalers, large enterprises and other customers. TLC-based MonTitan SSD solutions target high-performance, lower latency caching for the rapidly increasing demands within AI datacenters. The company has developed boot drive storage controllers and full solutions to address the growing opportunity in AI network accelerators, switches and other devices, and is expanding its boot drive portfolios leveraging PCIe and SATA as the market is increasingly a strategic focus.

The company is focused on expanding sales of eMMC and UFS controllers, which increased in the range of 20% to 25% year-over-year in 2025 to account for 40% to 45% of revenue, a higher percentage of net sales than the prior year. The company is also focused on developing new products for new applications to generate new sources of revenue to replace or build upon existing product revenue for applications that are mature or in secular decline. The company believes its future success depends on its ability to develop and introduce new technologies and products for new applications, and if it is unable to successfully expand sales of SSD controllers for data center and enterprise applications, its prospects for continued revenue growth could be adversely affected.

Gross profit as a percentage of net sales increased to 48% in 2025 as compared to 46% in 2024 primarily because of new projects and the company's ability to efficiently scale new products. Gross profit, excluding obsolete and unmarketable inventory write-downs, as a percentage of revenue increased from 47% in 2024 to 48% in 2025. The company's gross margin is highly dependent on product mix, especially the mix of higher gross margin controller sales and lower gross margin SSD solutions sales. The company's SSD solutions gross margin is materially lower than its controller gross margin because these products are generally less differentiated and, in the case of Ferri, where NAND flash components are the majority of the cost of sales, the company has limited ability to mark-up the cost of NAND flash components that it procures. The company has changed its commercial arrangement with a few SSD solutions customers to a NAND consignment arrangement, where customers procure and maintain ownership of the NAND flash components, and the gross margins of these types of sales are higher than sales of typical SSD solutions products.

The company relies on two outside foundries, primarily TSMC and secondarily SMIC, to fabricate its semiconductors, and does not own or operate semiconductor fabrication facilities. The company does not have long-term agreements with any of these foundries and subcontractors and places orders based on customers' purchase orders and sales forecasts. The company's ability to manufacture and deliver products depends on obtaining adequate supplies of raw materials, components and finished goods from third-party suppliers, including NAND memory and other semiconductor components. The potential shortages of key packaging components, including T-Glass substrates, could affect the company's ability to build SSD ICs and solutions. The company continues to work closely with suppliers to improve supply visibility and pursue alternate sourcing or contingency options. The company's R&D expenses increased by 21% year-over-year to approximately US$262.7 million ³² in 2025 primarily due to investing heavily in next generation solutions and significant employee additions.

R&D expenses were approximately US$174.4 million ³³, US$217.8 million ³⁴, and US$262.7 million ³⁵ for the years ended December 31, 2023, 2024 and 2025, respectively. Capital expenditures were US$50.3 million ³⁶, US$44.4 million ³⁷, and US$55.1 million ³⁸ for the years ended December 31, 2023, 2024 and 2025, respectively. On February 6, 2025, the board of directors authorized a share repurchase program to repurchase up to US$50 million ³⁹ of ADSs over a 6-month period. In the year ended December 31, 2025, the company repurchased approximately 426 thousand ⁴⁰ ADSs for US$24.3 million ⁴¹ at an average price of US$57.04 ⁴² per ADS. On October 28, 2024 and October 27, 2025, the company announced an annual cash dividend of US$2.00 ⁴³ per ADS to be paid in four quarterly installments of US$0.50 ⁴⁴ per ADS, paying US$67.3 million ⁴⁵ and US$67.2 million ⁴⁶ to shareholders in 2024 and 2025, respectively. The declaration and payment of future cash dividends is subject to the board of directors' continuing discretion.

The company faces headwinds from the cyclical nature of the semiconductor industry and the NAND industry, which regularly experiences cycles of shortages and excess supply and related rapid increases and sharp decreases in NAND component prices. During periods of NAND shortages, the company's sales and profitability could be negatively affected as module maker and OEM storage customers may not be able to procure sufficient supplies of NAND components, the company may not be able to procure sufficient NAND components for its Ferri industrial SSDs, NAND manufacturers may divert NAND supply away from their own storage products that use the company's controllers, and the higher cost of NAND components may lower end-product demand. During periods of NAND excess supply when NAND prices are falling sharply, the company's sales and profitability could also be negatively affected as NAND manufacturers may temporarily build NAND inventory, module maker customers may become more cautious in procuring NAND components, OEMs may temporarily limit procurement of storage devices, and NAND vendor and module maker customers under margin pressure may seek price concessions.

The company faces substantial risks associated with doing business in Taiwan because of tense regional geopolitical risk with China. Most of the company's business operations are in Taiwan, a self-governing democracy claimed by China, and a majority of employees and a significant portion of R&D and corporate functions are based in Taiwan. The company also operates an R&D center in Shanghai, and China is one of the largest markets for its products. All of the company's foundries and assembly and testing subcontractors are located in either Taiwan or China. The company generated 91%, 98% and 99% of its revenue in 2023, 2024 and 2025, respectively, from sales to customers outside the United States, and for the year ended December 31, 2025, 79% of revenue was from sales in three jurisdictions China, Japan and Singapore. The company is also subject to risks from government trade restrictions, entity list restrictions, sanctions, tariffs and quotas, including those imposed by the Trump administration on imported goods from several geographic regions including certain East Asian nations where the company operates.

The company depends on a few large customers for a significant portion of revenues, with sales to the five largest customers representing approximately 66% ⁴⁷ of net revenue in 2025, and the loss of any significant customer could materially and adversely affect financial condition and results of operations. The company is subject to the cyclical nature of the semiconductor and NAND industries, which regularly experience rapid changes in supply and demand, and during periods of NAND shortages or excess supply, the company's sales and profitability could be negatively affected in multiple ways. The company's international operations involve inherent risks including government trade restrictions, entity list restrictions, sanctions, tariffs and quotas, and the company generated 99% ⁴⁸ of its revenue in 2025 from sales outside the United States, with 79% ⁴⁹ from three jurisdictions China, Japan and Singapore. The company faces substantial risks associated with doing business in Taiwan because of tense regional geopolitical risk with China, as most of its business operations, a majority of employees, and all of its foundries and assembly and testing subcontractors are located in either Taiwan or China. The company's gross margin is highly dependent on product mix, and a shift in sales mix away from higher margin controller products to lower margin SSD solutions could adversely affect gross profitability, with the company having written down US$3.9 million ⁵⁰ of NAND components and SSDs in inventory in 2023 due to rapidly falling NAND prices.

Management's message emphasizes the company's position as a global leader in developing NAND flash controllers for SSDs and other solid state storage devices, highlighting over 20 years of experience and the shipment of over six billion NAND flash controllers in the last ten years. The strategic priorities emphasized for the period ahead include expanding into the enterprise market through the development of PCIe (MonTitan controllers and boot drive controllers and solutions) and SATA SSD controllers driven by AI and other high-performance applications, continuing to invest heavily in next generation solutions and significant employee additions as evidenced by R&D expenses increasing by 21% year-over-year to approximately US$262.7 million ⁵¹ in 2025, and pursuing payment of the termination fee of US$160 million ⁵² from MaxLinear through arbitration proceedings. The company also continues to focus on returning capital to shareholders, having announced an annual cash dividend of US$2.00 ⁵³ per ADS and a share repurchase program of up to US$50 million ⁵⁴.
