RE:Shareholder valuethey have done a really good job at cutting costs, in an effort to achieve profitibilty (which is a necessity when revenues aren't currently growing), however, splitting into two divisions will definitely increase costs as they now need management and admin staff for both divisions (where one person may have done that job for both cyber and EV/IOT/QNX with the combined company)....
it does make it much more easy to sell one or both of the divisions as the operations aren't co-mingled with with operations that a potential purchaser may not want...
as you said, what really matters is revenue growth....and until BB can start delivering multi-year revenue growth, the stock isn't going anywhere (barring any other significant announcement)....
