StockStory’s Take
onsemi’s fourth quarter was marked by an 11.2% year-over-year revenue decline, reflecting ongoing market headwinds and a cautious market reaction. Management pointed to continued softness in traditional segments but highlighted stabilization in automotive and the first signs of recovery in industrial. CEO Hassane El-Khoury noted, “Automotive inventory digestion is largely behind us, AI data center is increasingly becoming a meaningful growth engine for the company, and we believe we have seen the bottom for industrial.” Investments in advanced technologies, particularly in the AI data center and automotive content, were key areas of focus during the quarter.
Looking ahead, onsemi’s guidance reflects management’s expectation for a gradual recovery driven by expanding demand in AI data centers, ongoing product exits, and margin improvement from manufacturing optimization. El-Khoury emphasized, “The groundwork we have laid out over the last several years has positioned us to benefit as demand conditions continue to get better.” CFO Thad Trent cautioned that while gross margin expansion is expected, near-term profitability will depend on utilization rates and the successful execution of the company’s FabRite cost initiatives.
Key Insights from Management’s Remarks
Management attributed the quarter's performance to stabilization in automotive, growth in AI data center, and strategic portfolio shifts away from volatile non-core businesses.
- AI Data Center Expansion: The company delivered more than $250 million in AI data center revenue for the year, reflecting rapid adoption of its power management products in high-growth infrastructure. Management highlighted increasing design wins and a broad product roadmap, spanning from high-voltage to point-of-load solutions.
- Automotive Content Growth: Automotive revenue stabilized as inventory correction subsided, with onsemi increasing its share in next-generation vehicle architectures. The company surpassed $400 million in design funnel for zonal architectures, including smart power devices and Ethernet transceivers, targeting the growing market for software-defined vehicles.
- Industrial Segment Recovery: After several weak quarters, industrial revenue showed early signs of recovery, partly driven by demand in factory automation, machine vision, and robotics. The company’s US-based supply was cited as a differentiator for customers in sensitive applications.
- Product Portfolio Rationalization: Strategic exits from non-core and lower-margin businesses continued, with about $40 million in product exits during the quarter. Management indicated that these actions, while reducing short-term revenue, are intended to improve the long-term margin profile and reduce volatility.
- Manufacturing and Cost Initiatives: The FabRite program advanced, reducing fab capacity and operating expenses. Trent noted, “Our Q4 gross margin includes approximately 700 basis points of underutilization charges which will dissipate with increasing utilization as market conditions improve,” signaling the potential for future margin expansion.
Drivers of Future Performance
onsemi’s outlook is shaped by continued growth in AI data center demand, further product exits, and the impact of manufacturing optimization measures on margins.
- AI Data Center as Growth Engine: Management expects high-teens percentage growth in AI data center revenue next quarter, driven by expanded product offerings and design wins across global customers. The company sees this segment as a major contributor to baseline revenue growth as traditional markets recover.
- Product Exits and Portfolio Focus: Ongoing exits from volatile, non-core businesses are expected to continue through the year, totaling up to $300 million. While these exits create short-term revenue headwinds, management asserts they will help shift the mix toward higher-margin, differentiated products.
- Margin Expansion Dependent on Utilization: Gross margin improvement relies on higher fab utilization rates and the full effect of FabRite cost actions. Trent indicated that “as utilization goes up, that will impact later in the year as well,” but cautioned that progress depends on both market recovery and operational execution.
Catalysts in Upcoming Quarters
Going forward, the StockStory team will be monitoring (1) the pace of AI data center revenue growth and new design wins, (2) the impact of ongoing product exits on both reported revenue and margin mix, and (3) improvements in fab utilization and resulting margin expansion from the FabRite initiatives. Execution in automotive content growth and successful rollout of new GaN-based products will also serve as additional indicators of performance.
