The accelerating adoption and increasing technological dominance of Wide Bandgap (WBG) semiconductors, specifically Silicon Carbide (SiC) and Gallium Nitride (GaN), represent a clear emerging threat. While Alpha & Omega Semiconductor (AOSL) does have some WBG offerings, they are not a market leader in this rapidly expanding segment. SiC and GaN offer superior performance characteristics (e.g., higher efficiency, power density, and switching frequencies) compared to traditional silicon-based power devices, making them increasingly preferred in high-growth and high-value applications such as electric vehicles (EVs), EV charging infrastructure, renewable energy inverters, and data center power supplies. If the market shifts towards WBG technologies faster or more extensively than AOSL can adapt its product portfolio and gain market share, a significant portion of their traditional silicon-based power device revenue could be displaced, similar to how digital photography threatened film or streaming threatened physical media.

Alpha & Omega Semiconductor (AOSL) addresses several key markets with its power semiconductor products, which include power discrete products like MOSFETs, and power ICs for controlling and regulating power management variables. The company has a global presence, serving markets in Hong Kong, China, South Korea, the United States, and other international regions.

• The addressable market for the computing sector is estimated to be $2 billion.
• The power supply market is projected to reach approximately $45 billion globally by 2029.
• AOSL is also actively targeting the home appliances market, which represents a $2 billion market.

Additionally, AOSL is strategically expanding its focus into high-growth areas such as graphics, artificial intelligence (AI), and data center power applications.

• Expansion in High-Growth AI and Data Center Markets: AOSL is strategically positioning itself to capitalize on the increasing demand for power solutions in artificial intelligence (AI), graphics, and data center applications. The company is actively supporting advanced power architectures, such as 800 VDC for next-generation AI factories, utilizing its innovative SiC and GaN power devices to deliver efficient power delivery for escalating AI workloads. This focus aims to leverage the exponential growth in computational power required for machine learning and large language models.
• Continued Growth and Transformation in Power IC Segment: The Power IC segment has consistently demonstrated strong performance, achieving record quarterly highs and significantly contributing to AOSL's total product revenue. This growth is fueled by demand from the graphics, AI, gaming, and PC markets. AOSL is also transitioning from a component supplier to a comprehensive solutions provider, which is expected to further enhance its market position and gross margins.
• New Product Innovation, particularly in Wide Bandgap (SiC and GaN) Technologies: AOSL is investing in and developing advanced power management technologies, including wide bandgap semiconductors like Silicon Carbide (SiC) and Gallium Nitride (GaN). These technologies are crucial for addressing the increasingly complex power requirements of advanced electronics and are key to their offerings for high-voltage conversion and high-density DC-DC conversion in new applications like AI data centers.
• Strengthening Core Computing and Communications Segments: While navigating market dynamics, AOSL continues to build on its core strengths in the computing and communications sectors, including PCs and smartphones. The company has seen growth driven by product launches from Tier 1 smartphone customers and improved smartphone sales in certain regions, indicating sustained demand and market share capture with leading global OEMs.
