Smartphone pioneer BlackBerry has not been able yet to turn the corner on declining sales. The Canadian company reported more net losses as third-quarter business was sluggish and competition remained fierce.
BlackBerry reported a massive $4.4-billion (3.2-billion-euro) net loss in the third quarter, marking a 56-percent drop in revenue compared with the same period a year earlier.
It attributed the extent of the loss to a $4.6-billion charge for an inventory write-down and other one-off effects accumulating in the quarter under review.
The Waterloo-based firm presented its first quarterly earnings report under its new chairman and interim CEO, John Chen.
The firm's shares dipped 7 percent on the fresh figures in pre-market trading. BlackBerry has been trying to get back onto a sound footing by cutting thousands of jobs globally.
The company has also given up large parts of its production capacity, announcing a five-year partnership with Taiwan's Foxconn, the world's largest manufacturer of electronic components and devices.
