0932 ET - Trade tensions between the U.S. and Canada are weighing on BlackBerry's Secure Communications segment. In a call with investors, CFO Tim Foote defines the trade tensions between the two neighbors as "already dynamic" and that its substantial footprint with the U.S. government is being "further complicated by recent geopolitical developments." BlackBerry is revising the full year revenue forecast for Secure Communications segment to $260 million to $270 million and adjusted Ebitda outlook to be between $50 million and $58 million, down from $270 million to $280 million, and $57 million to $65 million, respectively. "We consider it appropriate to be cautious as we head into the second half," he says. Still, the company raised its full full-year targets on the back of strength in its embedded software unit, QNX.
