Analysis · BSX · Industrial Applications And Services
The August 25 cybersecurity incident will have a material impact on Q3 and full-year 2026 results, and the company now considers it unlikely to meet the net sales growth and adjusted EPS guidance ranges provided on July 29, 2026. This marks a significant escalation from the initial disclosure two weeks ago, which described operational disruption but did not quantify the financial impact. While some portion of impacted revenue is expected to be recovered as operations ramp, the full impact remains unknown. Management will provide an updated outlook on the October 28, 2026 earnings call. The company does not expect the incident to have a material impact on its long-term financial condition, but the near-term hit to results and the withdrawal of guidance are material negative developments for a $69 billion company.
