BlackBerry's Q4 shows strong revenue growth and share buybacks as it shifts fully to software and services.

BlackBerry has completed its transition from a hardware company to focusing on software and services, as reflected in its fiscal fourth quarter results. Despite earlier underperformance and cautious guidance, the company now expects stronger-than-anticipated revenue growth for the current fiscal year. Improved profitability and significant cash flow have enabled BlackBerry to start repurchasing shares, signaling renewed business momentum and confidence in its strategic direction.
