ON Semiconductor Corporation (ON) Stock Analysis & Winston Score

ON Semiconductor (onsemi) makes chips that control and manage electrical power in devices. Its main products are power semiconductors and sensors, sold to automakers, industrial equipment makers, and electronics companies. The company is a leading supplier of silicon carbide (SiC) power chips, which are a key component in electric vehicles and EV charging systems. Onsemi earns revenue by selling chips directly to manufacturers, with no subscription model — it lives and dies by unit volumes and pricing. The company operates globally, with major manufacturing in the US, Czech Republic, South Korea, and the Philippines, and generates roughly $7–8 billion in annual revenue. Its competitive edge comes from its focus on energy-efficient power management and its growing SiC capacity, but the main risk is heavy exposure to the automotive market, which has been slowing, putting pressure on chip demand and pricing.
