Research in Motion will lay off some 5,000 employees as it restructures itself this year.

The announcement comes as the tech giant reports an adjusted loss per share of $0.37 for the quarter ended May 31, missing analyst expectations for a loss of $0.07.

The news sent shares down nearly 20 percent in after hours trade, falling to nine-year lows.

Net sales tumbled more than 42 percent year-on-year, falling to $2.81 billion.

"I am not satisfied with these results and continue to work aggressively with all areas of the organization and the Board to implement meaningful changes to address the challenges, including a thoughtful realignment of resources and honing focus within the Company on areas that have the greatest opportunities," RIM's CEO Thorsten Heins said.

During the quarter, RIM shipped 7.8 million Blackberry devices, below the 8.74 million units Wall Street had projected. Playbook sales beat expectations slightly, as the firm sold 260,000 units, but were far lower than the 500,000 shipped in the year ago period.

Sales continue face pressure from the consumer shift to Apple and Android powered devices, which together account for more than three-quarters of the smartphone market.

The Blackberry manufacturer said it would delay its new operating system, Blackberry 10, until the first quarter of 2013.

"The integration of these features and the associated large volume of code into the platform has proven to be more time consuming than anticipated," RIM said in a statement.
