Boston Scientific Stock Slides After Cyberattack Caused ‘Global Disruption’

Boston Scientific shares lost ground Wednesday after the company disclosed a cyberattack that caused global disruptions to its operations.

The company said it's not sure yet when a full restoration of affected functions will be reached.

Boston Scientific's stock is sliding in the wake of a major cyberattack, adding to its recent woes.

Shares of Boston Scientific (BSX) shares were down about 3% in recent trading, after the Marlborough, Mass.-based firm disclosed in a regulatory filing that yesterday it "identified a cybersecurity incident affecting certain of its information technology systems that has resulted in a global disruption to the Company's operations."

The maker of medical devices said the incident "caused, and is expected to continue to cause, disruptions and limitations of access ... including the ability to process and ship customer orders." Boston Scientific added that it while it "is working diligently to restore affected functions and systems access, the timeline for a full restoration is not yet known."

Because Boston Scientific's investigation is ongoing, it said it "has not yet determined whether the incident is reasonably likely to have a material impact."

Shares of Boston Scientific have lost roughly half their value in 2026 so far.
