Phone company BlackBerry could survive as a much smaller player, an analyst has told Reuters, after it announced that it would cut around 40% of its global workforce.
BGC Partners analyst Colin Gillis said: "This is the end of the BlackBerry as we know it.
"This is a major pivot. They are cutting half of their employees and they're going to focus on becoming a niche player focused on the enterprise."
He added: "The company has sailed off a cliff...What do you expect when you announce you're up for sale? Who wants to commit to a platform that could possibly be shut down?"
The Ontario-based company BlackBerry said it expects that its adjusted net loss, will be in a range of about $250 million to $265 million (£165.4m) or a loss of 47 cents to 51 cents per share.
BlackBerry said it expects to report revenue for the second quarter of about $1.6 billion, of which roughly 50 per cent is expected to be revenue from its services unit.
The company said it plans to refocus its efforts on the enterprise and high-end consumer markets, offering end-to-end solutions, including hardware, software and services.
BlackBerry Ltd warned that it expects to report a huge second-quarter operating loss next week and that it plans to cut more than a third of its workforce.

Phone company BlackBerry has announced it is to lay off 4,500 employees, or 40 per cent of its global workforce.
The government is to begin testing an alert system for floods, industrial accidents and other hazards that uses text messages sent directly to people in affected areas.
Over the next three months, three pilots will take place in Easingwold in North Yorkshire, Leiston in Suffolk and Glasgow city centre. The text messages will be marked as a test and will ask recipients to provide feedback.
The government will test two methods of delivering the alerts: One using a conventional text message, which experts fear could be open to fraud, and a second using 'cell broadcast messages' that can only be sent by mobile operators.
Other countries already use the text alert system. In some states in the US they are used for missing children and prison escapes, while Japan and Chile use them to warn of natural disasters.
