BlackBerry Jumps 13.3% in a Week as QNX and Earnings Momentum Build

BlackBerry Limited BB shares gained 13.3% over one week, renewing attention on whether improving operating trends can sustain the move. Record QNX performance, stronger profitability and higher fiscal 2027 guidance provide fundamental support. The counterweight is valuation. With the stock trading well above its five-year EV/Sales median, continued upside may depend on QNX growth, cash generation and consistent execution across the company's businesses. BlackBerry's Weekly Rally Meets Stronger Fundamentals Second-quarter fiscal 2027 revenues rose 26% year over year to $163.3 million. Adjusted EBITDA climbed 81% to $47 million, representing 29% of revenues, as higher-margin QNX royalties and licensing supported operating leverage.
