onsemi reported second quarter 2026 revenue of $1,603.5 million, a 9% increase from $1,468.7 million in the prior year period, driven by accelerating adoption of its intelligent power solutions in AI data centers and automotive applications. The Scottsdale-based semiconductor manufacturer delivered non-GAAP diluted earnings per share of $0.74, significantly outpacing the $0.53 reported in the second quarter of 2025. This earnings growth was fueled by gross margin expansion to 39.3% on a non-GAAP basis, up from 37.6% year-over-year, and disciplined cost management that allowed earnings per share to grow four times faster than revenue.

The company’s operational performance improved markedly, with GAAP net income attributable to ON Semiconductor Corporation rising to $226.8 million from $170.3 million in the same quarter last year. Free cash flow quadrupled year-over-year to $425.4 million, reflecting a surge in cash from operations which increased by 150%. This liquidity strength enabled onsemi to execute share repurchases of $332 million during the quarter, bringing year-to-date shareholder returns to approximately 105% of free cash flow. The results exceeded the midpoint of management’s guidance across revenue, gross margin, and earnings per share metrics.

Segment Performance

Revenue growth was broad-based but led by the Power Solutions Group (PSG), which saw sales rise 19% year-over-year to $829.0 million. This segment benefited from increased customer adoption of Treo processors and high-voltage power solutions for AI infrastructure. The Analog Products Group (APG) generated $545.7 million in revenue, a slight decline of 2% from the previous year, while the Intelligent Sensor Solutions Group (ISG) posted revenue of $228.8 million, up 7% year-over-year. Total sequential revenue growth stood at 6%, indicating sustained momentum heading into the third quarter.

Strategic Developments

Beyond financial metrics, onsemi announced several strategic moves to expand its market position. The company confirmed plans to acquire Synaptics, aiming to enhance capabilities in connected compute at accretive gross margins. Additionally, onsemi expanded its role within the NVIDIA MGX ecosystem as AI infrastructure power demands accelerate. The firm also secured strategic platform wins with Great Wall, a leading China cloud infrastructure power supplier, expanding content for EliteSiC and silicon MOSFETs. New product launches included the GaNEXUS gallium nitride power portfolio, spanning 40V to 650V for AI data centers and robotics applications.

What the Numbers Show

A key analytical observation from the filing is the significant divergence between GAAP and non-GAAP profitability measures due to restructuring activities. While GAAP operating margin stood at 16.1%, non-GAAP operating margin reached 20.8%, excluding $75.5 million in special items such as restructuring charges and asset impairments. This suggests that core operational efficiency is improving rapidly, even as one-time costs pressure headline GAAP figures. Furthermore, the 150% jump in operating cash flow highlights strong working capital discipline, providing substantial flexibility for future capital allocation despite heavy investment in AI-related infrastructure.

Outlook

Looking ahead, onsemi provided guidance for the third quarter of 2026, projecting revenue between $1,650 million and $1,750 million. Management expects non-GAAP gross margin to range from 40.0% to 42.0%, indicating continued margin expansion. Non-GAAP diluted earnings per share are forecasted between $0.81 and $0.93. CEO Hassane El-Khoury noted that the AI data center business remains the fastest-growing segment, with expectations for full-year 2026 revenue in this area to more than double, underscoring the strength of the company’s intelligent power portfolio.

Onsemi (Nasdaq: ON) Chief Executive Hassane El-Khoury has confirmed that the AI data center segment remains the company's fastest-growing business, signaling a significant acceleration in demand for its power solutions. The company now expects revenue from this specific operation to more than double in 2026, a projection that underscores the robust market traction of its intelligent power portfolio and expanding customer adoption across the power tree. This growth trajectory highlights the critical role semiconductor power management plays in supporting the infrastructure demands of artificial intelligence applications.

The announcement reflects a strategic shift in Onsemi's revenue composition, with AI-related workloads driving disproportionate growth compared to other segments. El-Khoury emphasized that the doubling of revenue is not merely a function of volume but also demonstrates the depth of customer integration within the power tree. This indicates that clients are increasingly relying on Onsemi's components for core power delivery and management tasks within their data center architectures.

Strategic Implications

The expectation of more than doubling revenue in 2026 suggests that Onsemi is successfully capturing value from the ongoing AI infrastructure build-out. This growth is attributed to the strength of its intelligent power portfolio, which likely includes advanced silicon carbide and gallium nitride technologies essential for high-efficiency power conversion in data centers. The broadening adoption across the power tree implies that Onsemi is winning design-ins at multiple levels of the supply chain, from server boards to rack-level power distribution units.

Market Position

By highlighting the AI data center as the fastest-growing operation, Onsemi positions itself as a key beneficiary of the secular trend toward AI-driven computing. The company's focus on the "power tree" suggests a comprehensive approach to power management, rather than isolated component sales. This holistic strategy may provide competitive advantages in terms of system-level efficiency and reliability, which are critical factors for data center operators investing heavily in AI capabilities. The projected revenue surge serves as a tangible indicator of how deeply embedded Onsemi's technology has become in the evolving landscape of enterprise computing infrastructure.
