BlackBerry says it will lay off 4,500 employees, or 40% of its global workforce, as it reports a nearly $1bn (€1.35bn) second-quarter loss in a surprise early release of earnings results.
The stock dropped 19% to $8.50 after reopening for trading. Shares had been halted pending the news.
BlackBerry had been scheduled to release earnings next week. But the Canadian company said late this afternoon it expects a loss of about $950m to $995m for the quarter, including a massive inventory charge due to increasing market competition.
The BlackBerry, pioneered in 1999, was the dominant smartphone for on-the-go business people and other customers before Apple debuted the iPhone in 2007. Since then, BlackBerry Ltd has been hammered by competition from the iPhone as well as Android-based rivals like Samsung.
