Major competitors for power ICs include Monolithic Power Systems, Inc., ON Semiconductor Corp., Richtek Technology Corp., Semtech Corporation, Texas Instruments Inc., and Vishay Intertechnology, Inc. The company believes it can compete effectively through its integrated and innovative technology platform, strong and extensive patent portfolio, strategic global business model, expanding suites of new products, diversified and broad customer base, and excellent on-the-ground support and quick time to market. The company has an extensive patent portfolio consisting of 961 issued patents and 78 pending patents in the United States as of June 30, 2026 ¹, and a total of 991 foreign patents ².

The company generates revenue primarily from the sale of power semiconductors, consisting of power discretes and power ICs, with a small percentage of total revenue generated by providing packaging and testing services to third parties. The business model leverages global resources, including research and development and manufacturing in the United States and Asia, and utilizes both in-house facilities and third-party foundries and subcontractors. The company sells most of its products through distributors, with the two largest distributors, WPG Holdings Limited and Promate Electronic Co. Ltd., accounting for 53.0% and 19.3% of revenue, respectively, for the fiscal year ended June 30, 2026 ³. The company has direct relationships with key OEMs, including Dell Inc., Hewlett-Packard Company, Samsung Group, and Stanley Black & Decker, Inc., and ODM customers include Compal Electronics, Inc., Foxconn, Quanta Computer Incorporated, Wistron Corporation, and Delta Electronics.

The company's product portfolio consists of approximately 2,900 products ⁴, with two major categories: power discretes and power ICs. Power discrete products include low, medium, and high voltage power MOSFETs, IGBTs, and 1200V SiC products based on the AlphaSiC platform. Power IC products include DrMOS and smart power stage (SPS) families, EZBuck power ICs, smart load switches, and multiphase controllers.

The company also unveiled total power solutions for next-generation Intel platforms, the SmartClamp™ family of protected DrMOS for AI servers, 25V and 80V MOSFETs for AI server power demands, the αMOS E2™ 600V super junction MOSFET platform, 48V hot swap MOSFETs, and Type-C sink and source protection switches.

During the fiscal year ended June 30, 2026, the company entered into an equity transfer agreement on July 14, 2025, to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million ⁶ paid in four installments. On August 29, 2025, the amended Shareholders’ agreement was signed, reducing the company's equity interest in the JV Company by 20.3% to an ownership percentage of 18.9% ⁷. During fiscal year 2026, all conditions for installments were satisfied, and all installment payments were received. The company also continued its diversification strategy by developing new silicon and packaging platforms to expand its serviceable available market and offer higher performance products.

Total revenue for the fiscal year ended June 30, 2026 was $678.927 million ⁸, compared to $696.162 million ⁹ in the prior fiscal year. Cost of goods sold was $527.383 million ¹⁰ in fiscal 2026, compared to $535.158 million ¹¹ in fiscal 2025. Research and development expenditures were $103.9 million ¹², $94.3 million ¹³, and $89.9 million ¹⁴ for fiscal years 2026, 2025, and 2024, respectively. The effective tax rate was (21.0)% ¹⁵, 31.0% ¹⁶, and (138.1)% ¹⁷ for the fiscal years ended June 30, 2026, 2025, and 2024, respectively. The company recorded $0.0 million ¹⁸, $13.8 million ¹⁹, and $21.2 million ²⁰ of license and development revenue for fiscal years 2026, 2025, and 2024, respectively.

A key growth vector is the expansion into AI and datacenter applications. The company introduced the SmartClamp™ family of protected DrMOS designed for the extreme power demands of AI servers, data centers, and high-end graphics cards, and announced support for the 800 VDC power architecture for next-generation AI factories with innovative SiC and GaN, power MOSFET, and power IC solutions. This architecture is set to power the next generation of AI data centers, which will feature megawatt-scale racks to meet the exponential growth of AI workloads. The company also introduced 25V and 80V MOSFETs in state-of-the-art packaging that meets increasing AI server power demands, and enabled 48V hot swap in AI servers with new high SOA MOSFET in LFPAK 8x8. The company's multiphase controllers have enabled it to become a complete solution level provider across multiple compute platforms from PCs, graphics cards to AI and datacenter.

Another growth vector is the diversification into new markets beyond the computing base, including consumer, communications, and industrial markets. The company developed new technologies and products designed to penetrate into these markets, including IGBTs and integrated power modules for the home appliance market, as well as power ICs for personal computing, advanced computing, and gaming applications. The company expanded its high voltage 600V and 700V MOSFET portfolio based on its aMOS5 technology platform to address demanding consumer and industrial applications, and deployed its 1200V SiC products based on the AlphaSiC platform for high efficiency, high density industrial applications such as solar inverters, UPS, and battery management systems. The company also introduced higher voltage drivers to expand success beyond PCs to motor drive applications such as power tools and garden equipment.

The company expects to continue to exercise cost control measures in response to the declining PC market and align operating expenses to the revenue level. The company's gross margin is affected by manufacturing costs, utilization of manufacturing facilities, product mix, pricing of wafers from third-party foundries, and pricing of semiconductor raw materials. Capacity utilization affects gross margin because of fixed costs at the Shanghai facilities and the Oregon Fab. The company believes its market diversification strategy and product growth will drive higher volume of manufacturing which will improve factory utilization rates and gross margin in the long run.

The company operates an 8-inch wafer fabrication facility in Hillsboro, Oregon, which is critical for accelerating proprietary technology development and new product introduction. The company allocates wafer production between its in-house facility and third-party foundries, with wafers from third-party suppliers accounting for approximately 35% of total wafer supply ²¹. The company's in-house and wholly-owned packaging and testing facilities are located in Shanghai, China, with combined capacity to package and test over 600 million parts per month ²². The company continuously increases the outsourcing portion of its packaging and testing requirements to other contract manufacturers to improve its ability to respond to changes in market demand. The company also maintains a strong relationship with the JV Company, which provides a monthly wafer production capacity guarantee.

The company continues to invest significantly in research and development, with expenditures of $103.9 million ²³ in fiscal year 2026. The company intends to continue exploring opportunities to expand its manufacturing capabilities, including acquisition of existing facilities, formation of joint ventures or partnerships with third parties, or applying for government funding or grants in the semiconductor industry. The company has never declared or paid cash dividends on its common shares and currently intends to retain all available funds and any future earnings for use in the operation of its business, not anticipating paying any dividends in the foreseeable future. The company did not repurchase any common shares during the fourth quarter of fiscal year 2026.

A significant headwind is the decline of the personal computing market, which has had a material adverse effect on results of operations. The PC market has experienced a modest global decline in recent years, and in the first half of 2026, the semiconductor industry experienced a severe constraint in memory supplies driven by data center AI infrastructure demand, which adversely affected demand in the PC market. The company cannot predict when the current memory constraint will end and whether the PC market will return to a more normalized level. The company's diversification strategy may not succeed according to expectations and may expose it to new risks and place significant strains on management, operational, financial, and other resources.

Geopolitical and economic conflicts between the United States and China may adversely affect the business. The U.S. has implemented, proposed, and continues to evaluate changes to tariffs and other international trade measures, and the ultimate level of tariffs and their impact on the business is uncertain. The company believes that the imposition of additional tariffs by the U.S. government on products incorporating its power semiconductors could deter customers from purchasing products originating from China, which would reduce demand or result in pricing adjustments that would lower gross margin. The company's operations in China are subject to complex and evolving PRC data security, data privacy, and cybersecurity laws, and any non-compliance could subject it to severe penalties, operational disruptions, or structural changes.

The company's operating results are significantly affected by downturns in the semiconductor industry and changes in end-market demand, particularly the decline of the personal computing market, which has had a material adverse effect on results of operations. The company's revenue is highly concentrated in two distributors, WPG and Promate, which collectively accounted for 72.3% ²⁴ of revenue in fiscal 2026, and the loss of either could harm the business. The company's lack of control over the JV Company, in which it holds an 18.9% ²⁵ equity interest, may adversely affect its ability to secure sufficient manufacturing capacity. The company faces intense competition from larger competitors with greater resources, and its average selling prices have historically declined rapidly. Geopolitical and economic conflicts between the United States and China, including tariffs and evolving export control regulations, could materially adversely affect the business, and the company's operations in China are subject to complex and evolving data security and cybersecurity laws that could result in severe penalties or operational disruptions.

Management's message emphasizes the company's position as a designer, developer, and global supplier of a broad portfolio of power semiconductors, with a focus on diversification and expansion into new markets beyond its computing base. The company has accelerated the development of new technology platforms, introducing over 70 new products in the fiscal year ended June 30, 2026 ²⁶. Management highlights the sale of approximately 20.3% of the JV Company equity interest for $150 million ²⁷ as providing additional and significant capital to continue investment in technology, new product development, and acquisition of assets complementary to business operations. The strategic priorities emphasized are expanding the product portfolio to increase total bill-of-materials within electronic systems, leveraging power semiconductor expertise to drive new technology platforms, increasing direct relationships with OEM and ODM customers, and leveraging the global business model for cost-effective growth. Management also emphasizes the importance of the Oregon Fab for accelerating proprietary technology development and improving financial performance, and the continued strong relationship with the JV Company to support manufacturing capacity.
