Boston Scientific reported that a cyberattack detected on August 25 caused a disruption that will likely result in a material impact on its third-quarter and full-year results. The company stated it is unlikely to meet the net sales growth and adjusted earnings-per-share guidance ranges established in July.

While the company expects to recover some revenue as it clears the backlog, it has not yet determined the full financial cost of the incident. Boston Scientific noted that it has substantially restored its distribution network, and its sterilization facilities and manufacturing sites are operational. The company confirmed that the interruption affecting new patient activations for remote monitoring of cardiac devices has been resolved. Boston Scientific stated that there is no evidence of ongoing unauthorized access to its systems. However, the company has not yet disclosed how the attackers entered the network, whether ransomware was involved, or if any data was stolen. The company does not expect the incident to materially affect its long-term financial condition, though it noted that its 2026 outlook is less healthy due to the breach.
