Shares of BlackBerry (TSE:BB) were trading about 2 percent higher as the company said it has replaced its sales director.
Carl Wiese will succeed John Sims, who joined the company 18 months ago as part of wider changes within the smartphone manufacturer’s management.
Wiese was previously employed by Cisco Systems and has also held positions at Apple, Avaya, Lucent and Texas Instruments.
The outgoing Sims had joined BlackBerry in January 2014, shortly after the arrival of the current CEO, John Chen.
BlackBerry said Mr. Sims had left the company, but offered no other details.
John Chen is now working to change BlackBerry, but revenues of US$658 million in the first quarter failed to meet analysts’ expectations by US$21 million.
Chen's recovery plan is premised upon the launch of new software services and the establishment of new partnerships with its corporate customers and wireless service providers, in a move away from hardware and more towards special services.
