Boston Scientific’s Cyberattack Nightmare Could Be Bigger Than 4%!

Boston Scientific has been hit by a cyberattack at one of the worst possible moments for the medical-device giant. The incident triggered a global outage affecting information systems and business applications used for order processing and shipping, leaving management unable to say when normal operations would be restored. Shares fell more than 4% in early trading after the disclosure, but the bigger question is whether the financial consequences could extend beyond the initial market reaction. The timing is especially important because Boston Scientific had already reduced its 2026 outlook following unexpected weakness in WATCHMAN and increased competitive pressure in its U.S. Electrophysiology business. Management was also preparing investors for a difficult 2027 while undertaking a major restructuring.
