ON Semiconductor Corporation (which operates commercially under the brand name onsemi) does not have a parent company because it is an independent, publicly traded enterprise listed on the Nasdaq Global Select Market under the ticker symbol ON. Rather than being a subsidiary of a larger corporate conglomerate, onsemi functions as a primary corporate parent entity that owns and operates numerous global subsidiaries, manufacturing fabrication plants, and design centers worldwide, specializing in intelligent power and sensing technologies for automotive, industrial, and cloud power markets.
