Full Analysis
ON Semiconductor (ON) is currently trading at approximately 27.6 times trailing adjusted earnings, which the article deems expensive given the recent weakness in sales. However, this valuation perspective shifts significantly when looking forward to analyst consensus estimates for 2026 and 2027, where the stock price implies multiples of roughly 23.7x and 17.2x respectively. The company is navigating a transition period where it has exited about $900 million in non-core annual revenue over recent years, with this phase concluding in Q2 2026. The core investment thesis relies on the assumption that margins will continue to expand significantly faster than revenue growth through 2027. Management expects adjusted gross margins to rise from 39.3% in Q2 2026 to a guided range of 40% to 42% for Q3 2026, driven by factory utilization improvements and anticipated price increases to offset rising input costs. Analysts forecast earnings growth of roughly 37.5% annually compared to revenue growth of about 12.7%, creating a substantial gap that hinges on operational efficiency. Key drivers for this margin expansion include surging demand in the AI data center sector, where revenue is expected to more than double in 2026 and lead times have stretched from 27 weeks to 32 weeks. The automotive segment remains the largest market, contributing $781 million in Q2 2026 revenue. Additionally, ON has agreed to acquire Synaptics, a deal expected to close by mid-2027, which is factored into current analyst pricing models.
