Boston Scientific warns cyberattack will impact 2026 financial guidance

Boston Scientific has issued a warning that a recent cybersecurity incident is likely to have a material impact on its third-quarter and full-year 2026 financial results. The company stated it is unlikely to meet the net sales growth and adjusted earnings-per-share ranges previously provided in July.

The cyberattack, first disclosed in late August, disrupted global operations, including manufacturing, order processing, and shipments. While the company is working to fulfill backlogged orders and ramp up operations, the incident has impaired its ability to ship products effectively.

Following the announcement, the company's stock experienced a significant decline. Investors are now awaiting an updated outlook, which management expects to provide when third-quarter results are released on October 28. Despite the guidance warning, Boston Scientific noted it does not expect the incident to have a material impact on its long-term financial condition.
