Cybersecurity Incident Disruption

BOSTON SCIENTIFIC CORP · 2026-11-02 · Importance 53 · Surprise 68

Boston Scientific identified a cybersecurity incident in August 2026 that disrupted global operations, including manufacturing and the processing and shipment of customer orders. The company said the incident materially impacted third-quarter financial results and reduced reported net sales growth to 1.5% for the quarter. Idle production time and related supply-chain costs contributed to lower gross margin, while incremental incident-related expenses also affected SG&A. The incident was cited as a factor in lower quarterly net income and in sales declines or slower growth across several businesses.
