BlackBerry is expected to report earnings for its November quarter on Friday that show substantial declines across the board. Most significantly, perhaps, the vendor is seen posting a loss of -$0.46 per share compared to a -$0.22 per share loss in the same quarter last year, and it may also once record a massive write-down related to unsold smartphone inventory. As investors wait to hear interim CEO John Chen’s plan to turn things around, some more troubling news has emerged: according to The Wall Street Journal, two more top BlackBerry executives will soon be leaving the company. The paper reports that BlackBerry’s M&A boss Chris Wormald will be gone by the end of December and Rick Costanzo, the company’s EVP overseeing global sales, will depart early next year. BlackBerry wouldn’t confirm the moves, which would mark the latest in a long line of executive departures.
