The setup for MCHP
Microchip Technology is incorporated in Delaware and operates from 2355 West Chandler Boulevard, Chandler, Arizona. Its common stock trades on the Nasdaq Global Select Market under MCHP. The company also carries depositary shares, each representing a 1/20th interest in a share of its 7.50% Series A Mandatory Convertible Preferred Stock, which trade under MCHPP on Nasdaq.
The filing says nothing about whether Microchip Technology plans to promote internally, run an external search, or redistribute operating responsibilities across the existing leadership structure.
