Blackberry has reported a second quarter net loss of $965m (£600m) following a slump in sales. The company warned investors last week that it would report a loss of up to a billion dollars, due to poor sales of its new smartphones.
It also announced 4,500 job cuts in a bid to stem those losses.
Earlier this week Blackberry agreed to be bought by a consortium led by Fairfax Financial, its biggest shareholder, for $4.7bn (£3bn).
Blackberry said it would continue to explore other options while negotiations with Fairfax continued.
The company's financial problems came to a head this year following disappointing sales of its new Z10 smartphone.
Sales were so poor that Blackberry had to write off $934m in the second quarter to account for the weakness.
