By the time Giamatteo joined BlackBerry in 2021, Chen's lustre was long gone. The veteran Silicon Valley turnaround artist had arrived eight years earlier, initially skeptical he could fix the floundering smartphone franchise but lured with that rich stock award. BlackBerry was in full-blown crisis. Its touchscreen phones, based on the new BlackBerry 10 operating system, were a flop. During Chen's first few months, BlackBerry shed thousands of employees, wrote down unsold phone inventory and sold off most of its real estate. That year, BlackBerry posted a $5.9-billion net loss.
