The other executive officers all joined from outside since late 2021. Derek P. D'Antilio has been chief financial officer since January 2022, after finance posts at IDEX Biometrics and MKS Instruments, and sits on Polar Semiconductor's board for Allegro. Sharon S. Briansky, general counsel since December 2021, came from Thermo Fisher Scientific. Erin E. Hagen has run human resources since May 2024. Richard A. Madormo joined as head of worldwide sales in March 2025 from Wolfspeed. Troy T.

Joseph R. Martin, a director since 2017 and once co-chairman and finance chief of Fairchild Semiconductor, has chaired the board since August 2025. He took over from Yoshihiro (Zen) Suzuki, a director since 2001 and chairman from 2018, who spent more than 40 years with Sanken and its affiliates and ran Polar Semiconductor from 2005 to 2022. Sanken Electric, which held about 32.2% of the shares in March 2026, names two directors under a stockholders agreement dating from Allegro's 2020 listing: Katsumi Kawashima, a Sanken senior vice president, and Robert J. Willett, put forward in place of Richard R. Lury, who is not standing for re-election. Brian C. White, a former finance chief of Ambarella, joined in June 2026. With Lury and Susan D. Lynch not standing again, the board of eleven is to shrink to nine after the 2026 annual meeting. 10111213141516171819
