Directors and officers of ON Semiconductor Corporation
Zavia’s registry data lists 12 disclosed officer records for ON Semiconductor Corporation, of which the available detail covers 5, and describes them as active as of the last synchronization on September 15, 2026. Cross-checked against the company’s official leadership page and SEC filings, the current named executive officers include Hassane El-Khoury as President, Chief Executive Officer and Director; Thad Trent as Executive Vice President and Chief Financial Officer; Felicity Carson as Senior Vice President and Chief Marketing Officer; and Parag Agarwal as Vice President, Investor Relations and Corporate Development. A discrepancy was identified for Simon Keeton: the registry record marks him "active" as Group President, Power Solutions Group, but a Form 8-K filed with the SEC confirms he stepped down from all officer positions effective March 9, 2026, so he is treated here as a former officer. Nationality is not disclosed in any reviewed source for any of the named individuals; correspondence-address countries shown in the registry (for example, the United States or Australia) reflect an official correspondence address only and are not evidence of nationality or residence.
Recent officer changes
- Simon Keeton stepped down from all officer positions, including Group President, Power Solutions Group, effective March 9, 2026, as mutually agreed with the company (SEC Form 8-K filed May 18, 2026). His last day of full employment, initially set for June 30, 2026, was subsequently extended to September 30, 2026, on May 14, 2026, to support an orderly transition.
- Achyut Shah is named on onsemi’s official leadership page (retrieved September 16, 2026) as Group President, Power Solutions Group, succeeding Mr. Keeton; the exact effective date of this appointment was not disclosed in the sources reviewed.
Data availability
ON Semiconductor Corporation is a U.S.-listed company; its officer roles and appointment or resignation events are disclosed through SEC filings and company announcements, but nationality is not a field these sources report, so it is stated as not disclosed for all individuals. The registry’s "active" status for Mr. Keeton is outdated relative to the SEC filing referenced above.
