Before Friday evening, you’d have been forgiven for thinking things couldn’t get much worse for BlackBerry, given the company’s plummeting smartphone market share over the last three years. But yes, they could get worse. In preliminary financial results for its quarter that ended on 31 August, BlackBerry says it’ll report a net operating loss of between $950m and $995m, including writing down between $930m and $960m on charges “resulting from the increasingly competitive business environment impacting BlackBerry smartphone volumes”. BlackBerry also announced plans to lay off around 4,500 staff; said it expects to have sold 3.7m smartphones in that latest quarter (compared to 7.4m in the same quarter last year, and 10.6m in 2011); and said it will try to refocus its business on “enterprise and prosumer” customers. Yet while this was being announced, BlackBerry’s launch of its BBM messaging app for iOS and Android was falling apart – by Saturday, the company was “pausing” the global rollout after a leaked version of the Android app “caused issues”. The company continues to seek buyers for all or parts of its business.
