Boston Scientific (BSX) Didn’t Miss on Demand or Devices. A Cyberattack Just Broke Its Guidance.
Boston Scientific (BSX) fell 2.3% after a cyberattack disrupted operations, leading to a guidance cut for Q3 and 2026. The attack caused shipping delays, not demand issues, and the company expects recovery. BSX faces competitive pressure in the electrophysiology market. Hedge fund holdings decreased slightly, with low short interest. The company's long-term outlook remains intact, but near-term visibility is weak.
