onsemi Beats Q2 Estimates as AI Data Center Revenue Doubles

As of 8:30 PM ET on August 3, 2026 (8:30 AM Beijing time on August 4), onsemi (ON) was trading at $206.64, up 2.93% (+$5.89) from the previous session's close of $200.75. The stock opened at $197.69, hit an intraday high of $208.74, and touched a low of $196.85. The move came after onsemi reported Q2 FY2026 results after the bell on August 3, with both revenue and profit topping market expectations^{[Investing.com]}.

Revenue Back to Growth, Ending a Slump

onsemi posted Q2 FY2026 revenue of $1.6 billion, up 9.2% YoY — a return to growth after a stretch of declining sales. According to StockStory, onsemi's revenue had been falling at an annualized rate of 10.8% over the past two years, making this quarter's 9.2% uptick a clear reversal of that trend^[StockStory]. The quarter's revenue came in 0.9% above Wall Street's expectations^[StockStory].

Still, the rebound doesn't erase the longer-term picture. onsemi's trailing twelve-month revenue of $6.2 billion is roughly where it was five years ago — a performance StockStory flagged as "below our standards and a sign of poor business quality"^[StockStory]. Semiconductors are a deeply cyclical business, and long-term investors should expect periods of strong growth to alternate with revenue contractions^[StockStory].

Management guided Q3 FY2026 revenue to grow 9.6% YoY, with a midpoint of roughly $1.7 billion — 1.6% above analyst estimates^[StockStory]. Sell-side analysts expect revenue to grow 10.7% over the next twelve months, a forecast that implies new products and services will drive improvement — though still below the industry average^[StockStory].

Profit Beats, AI Data Center Business Shines

On the bottom line, onsemi posted non-GAAP EPS of $0.74, 3.5% above analyst consensus^[StockStory]. Per Investing.com, the company's earnings deck showed margins expanding and AI data center revenue doubling year over year^{[Investing.com]}.

onsemi is an analog chipmaker spun out of Motorola that began operating independently in 1999, growing through a series of acquisitions and focusing on power management for automotive, industrial applications, and cloud data centers^[StockStory]. The rapid growth of its AI data center business is giving the company, traditionally tied to auto and industrial chips, a fresh growth engine.

Inventory Improves, Cycle Signals Watched

Days inventory outstanding (DIO) is a key metric for chipmakers, reflecting both capital intensity and the cyclical nature of semiconductor supply and demand. In tight supply environments, inventory tends to stay stable and chipmakers gain pricing power; a persistently rising DIO, by contrast, can signal weakening demand — and if inventories keep climbing, companies may have to cut production^[StockStory].

This quarter, onsemi's DIO came in at 189 days, an improvement in inventory levels^[StockStory]. The market read the change as a positive sign that the inventory overhang that had been weighing on the company is easing.

Peers Report Strong Results, Sector Momentum Builds

onsemi's report landed amid a wave of upbeat earnings from across the semiconductor supply chain, pointing to a sector-wide recovery. Chip test equipment maker Cohu (COHU) reported on July 30 that Q2 revenue rose 38% YoY to $149 million, and lifted its FY2026 revenue growth outlook from 25% to 35%^{[Motley Fool]}. Cohu's management said its annualized addressable opportunity in high-performance computing (HPC) pipelines has reached $850 million, up from $750 million last quarter^{[Motley Fool]}.

Semiconductor test equipment supplier Teradyne also beat Q2 estimates, with growth driven by AI demand^{[Investing.com]}. And Wacker Chemie raised its full-year 2026 outlook after a strong Q2^{[Investing.com]}. The synchronized improvement across multiple semiconductor and materials companies suggests demand is gradually recovering across the industry.
