Overview
- Boston Scientific detected unauthorized activity on some IT systems on August 25 that caused a network outage and disrupted manufacturing, sterilization and order shipments.
- The company says it has restored most systems, major distribution centers are processing orders at or above normal levels, sterilization sites are operational and manufacturing has resumed at most facilities.
- On September 8 Boston Scientific said it now expects to miss its prior third-quarter and full-year 2026 sales and adjusted EPS guidance because the outage curtailed order fulfillment and production.
- The firm has engaged outside cybersecurity specialists, reports no evidence so far of ongoing access, and says it expects to recover part of the lost revenue as backlogs are cleared.
- Investors reacted with a modest premarket stock decline and the incident adds to a broader 2026 pattern of cyberattacks on medtech and healthcare firms that could affect hospital supplies and sector confidence; a detailed financial impact will be given on October 28.
