Revenues were down 45 per cent from the same period last year, the Waterloo, Ont.-based company said Friday.
BlackBerry said it booked sales of 3.7 million smartphones in the quarter, a drop of 74 per cent from the 14.5 million it sold in its best quarter ever, almost three years ago.
"We are very disappointed with our operational and financial results this quarter and have announced a series of major changes to address the competitive hardware environment and our cost structure," chief executive Thorsten Heins said.
BlackBerry had already telegraphed that its second-quarter results would include a loss of between $950 million to $995 million on $1.6 billion in sales, far short of analysts' expectations of about $3 billion.
The results include a pre-tax inventory charge of $934 million and restructuring charges of about $72 million, the company said.
BlackBerry said in a statement earlier this week that it decided to cancel its usual post-earnings conference call "in light of the letter of intent agreement between BlackBerry and FairfaxFinancial Holdings Ltd."
The letter of intent values BlackBerry at $4.7 billion but allows Fairfax to walk away from the offer if it is dissatisfied with a number of conditions.Suggest a correction
