The long-suffering mobile-device maker reports results today. John Chen, the firm’s boss since 2013, has been pushing it away from its once-beloved gadgets: 23m people still use them, but that number has fallen by three-quarters in two years. In the past year he has spent hundreds of millions of dollars acquiring companies that help secure businesses’ internal communications, including WatchDox and Good, and pushed into new areas such as cyber-security consulting. Sceptical investors will take some convincing, though. Shares are down by a fifth over the past 12 months. In an ironic twist, falling handset sales may change their attitudes for the better—Mr Chen has said he will close the hardware unit if it doesn’t start making money by September. That would reduce costs and complete the company’s transformation. Sometimes powering down is the only way to get something working again.
