What it says

  • On August 25 the company detected an incident that caused a global disruption of its operations, including order processing and shipping.
  • There was unauthorized activity on some systems and a network outage that affected manufacturing, order processing, and shipping.
  • As of September 7 it had not detected any ongoing unauthorized access: the large distribution centers were already shipping at normal or higher levels, the sterilization plants were operating, and manufacturing had resumed at most facilities.
  • It considers it unlikely to meet the sales growth and adjusted earnings per share guidance for the third quarter and for all of 2026 that it gave on July 29.
  • It has not explained how the attackers got in or who is behind it.

Our take

A medical device manufacturer was left unable to manufacture or ship for days by an attack on its management systems, not on its products. If your company depends on a critical supplier, ask how it would fulfill orders without its systems and whether it would warn you in time. And ask yourself the same question about your ERP: how many days can you last without it?
