ON Semiconductor’s (NASDAQ: ON), which operates under the Onsemi brand, stock price action was mixed following its Q4 2025 earnings report and guidance update, but the initial sell-off proved to be a head fake. While results and guidance left some to be desired relative to consensus forecasts, they affirmed the company’s return to growth, expectation for margin improvement, free cash flow growth, and capital return.
Free cash flow is a significant factor for this company, as its balance sheet is a fortress, enabling it to use 100% of free cash flow for buybacks. Investors have to assume that a return to revenue growth compounded by wider margins and accelerated earnings growth will lead to accelerating buyback activity and a strengthening tailwind for ON share prices.
