AI brief of an SEC Form 8-K · Boston Scientific (BSX)

Boston Scientific cyber incident disrupts operations, 2026 guidance unlikely to be met

Negative Impact 5 of 5 other Written later

Boston Scientific said a cybersecurity incident identified on August 25, 2026 caused a global disruption to its operations, including manufacturing, order processing and shipping. The company believes the incident is likely to materially affect its third quarter and full year 2026 results, and it is unlikely to meet the net sales growth and adjusted EPS guidance it gave on July 29, 2026. The filing does not quantify the financial impact, and the company says the full effects are not yet known.

Key points

  • Incident identified August 25, 2026; the company activated incident response protocols with third-party cybersecurity experts.
  • Company is unlikely to meet previously provided net sales growth and adjusted EPS guidance for Q3 and full year 2026 (guidance issued July 29, 2026).
  • Major distribution centers are processing and shipping at or above normal levels, and manufacturing has resumed across most facilities; full recovery timing is uncertain.
  • Updated outlook for the rest of 2026 is expected on the Q3 earnings call on Wednesday, October 28, 2026; the company does not expect a material long-term impact on its financial condition.
