According to Fortune, the executive appointment comes nearly two years after a board-level independent investigation led the company to commit to immediately search for a replacement for David Weigand in December 2024. Mark Long previously served as chief financial officer and chief strategy officer at data storage company Western Digital, and he currently runs the investment and advisory firm Prime Impact Capital, Fortune reported.
