Management pointed out that driven by the "Fab Right" manufacturing strategy, improved capacity utilization, and optimization of high-value product portfolios such as AI data centers and automotive electrification, gross margin has further room to rise. The company estimates that every 1 percentage point increase in factory utilization can contribute 25-30 basis points of gross margin expansion.

From a cash flow and capital allocation perspective, the company repurchased $345.7 million worth of stock in the first quarter at an average price of $60.54. Previously, the company announced a three-year, $6 billion stock repurchase authorization, effective January 1, 2026. This capital return plan reflects management's confidence in the company's long-term value creation capability.

How AI Data Centers and Silicon Carbide Form the Dual Engines of Growth

ON Semiconductor's current core growth narrative revolves around two keywords: AI power management and silicon carbide (SiC) technology.

In the AI data center field, the company is experiencing an "inflection point" explosion in demand. In the first quarter of 2026, AI data center revenue grew more than 30% sequentially and more than doubled year-over-year. Management currently expects AI data center revenue for the full year 2026 to double year-over-year. This growth driver comes from the widespread adoption of efficient power conversion and management solutions by hyperscale cloud service providers, GPU, and CPU platforms. The company predicts that the power semiconductor value per single AI cabinet will jump significantly from the current $15k to over $110k.

ON Semiconductor's product portfolio covers the entire AI power chain—from the grid to processors inside data centers—including silicon carbide, gallium nitride, intelligent power modules, and mixed-signal technologies. This breadth positions the company favorably to capture opportunities in the AI infrastructure investment wave.

The company disclosed that nearly 55% of new electric vehicle models unveiled at the 2026 Beijing Auto Show adopted its silicon carbide technology. The company is collaborating closely with major Chinese automakers such as Geely and NIO to support next-generation 900V electric vehicle platforms. The 900V architecture enables faster charging speeds and longer driving ranges, with silicon carbide devices being a key enabling technology for this transformation. ON Semiconductor's long-term cooperation with NIO has expanded to next-generation 900V platforms, including its latest flagship SUV model, the ES9.

Why Is the Breakthrough in the Chinese Electric Vehicle Market Strategically Significant

China is the world's largest electric vehicle market, and its technical standards are increasingly influencing the global development direction of the electric vehicle industry. ON Semiconductor's performance in the Chinese market is noteworthy: despite the overall weakness in China's passenger car market in the first quarter of 2026, the company's Chinese automotive business revenue achieved year-over-year growth. This "counter-trend growth" indicates that the company is gaining higher content per vehicle and market share.

Management pointed out that Chinese automakers are driving the transition to more efficient vehicle architectures, creating long-term structural demand for ON Semiconductor's power semiconductors. As Chinese electric vehicle exports continue to grow, the company's market opportunities are expanding from the domestic Chinese market to the global stage. Driven by regional automotive electrification and intelligent driving trends, ON Semiconductor's market position in automotive power semiconductors is expected to further strengthen.

Notably, ON Semiconductor recently announced it would cut approximately 200 to 300 employees from its silicon carbide wafer manufacturing facility in Rožnov, Czech Republic. This decision is set against the backdrop of Chinese silicon carbide suppliers leveraging government subsidies and low electricity prices to reduce wafer production costs to about one-third of their Western counterparts. This event highlights the cost competitive pressures the company faces in the silicon carbide field, while also indicating that the company is proactively adjusting its capacity layout to respond to market changes.
