ON Semiconductor Corporation (ON)

Hassane El-Khoury has been president, chief executive and a director of ON Semiconductor, which trades under the onsemi brand, since December 2020. He came from 13 years at Cypress Semiconductor, which he ran as chief executive from August 2016 to April 2020. Two of his top lieutenants are Cypress veterans too: Thad Trent, chief financial officer since February 2021, was Cypress's finance chief from June 2014 until its sale to Infineon in April 2020, and Sudhir Gopalswamy, who joined in March 2022 and now leads both the sensing (ISG) and analog (AMG) groups, worked at Cypress from 2008 until Infineon bought it. Simon Keeton, with onsemi since July 2007, has been group president of the power business, PSG, since February 26, 2024. 123456

The board keeps the chair separate from the chief executive, and every director except El-Khoury is independent. The chair, Alan Campbell, is retiring at the 2026 annual meeting; the board picked Thomas L. Deitrich, chief executive of Itron since 2019 and a former Freescale Semiconductor general manager, to succeed him, and is shrinking to seven directors. Paul A. Mascarenas, who was at Ford Motor Company from 1982 to 2014 and its chief technical officer from 2011 to 2014, has been a director since 2014, and Susan K. Carter, a former chief financial officer of Ingersoll Rand, KBR and Lennox International, since 2020. 7891011121314
