The company's stock dropped 4% in after hours trading.
The three now ex-BlackBerry execs are VP of corporate information technology operations Doug Kozak, Sr. VP of global manufacturing and supply chain Carmine Arabia, VP of service operations Graeme Whittington.
A spokesperson for BlackBerry told VentureBeat in an email:
"As previously stated, we are in the second phase of our transformation plan where we will be assessing our organization – from top to bottom – to ensure we have the right people in the right roles with the right skill sets to drive new opportunities in mobile computing. We will be as transparent as possible as plans evolve."
David J. Smith, who ran BlackBerry’s Playbook tablet operations, quit last month. BlackBerry is still a sizable operation, generating $3.1 billion in revenue last quarter (up 9% year to year), but it still lost $84 million.
The company said it's shipped 2.7 million of its Z10 smartphones.
