Research In Motion posted fourth-quarter results last night, and the figures aren’t pretty: The company missed targets on several fronts and reported a net loss of $125 million due to two major charges. But more telling was the earnings call with new CEO Thorsten Heins, who stated flatly “substantial change is what we need.” That’s an about-face from statements Heins made just after he took the job 10 weeks ago, when he said the company was largely headed in the right direction. But it’s interesting to note that despite the disappointing earnings, shares of RIM are up about 4 percent this morning. Which indicates that Heins is finally grasping something investors have known for quite some time.
