Henry Schein takes systems offline after an incident in its manufacturing and distribution businesses

Compiled 2026-09-27 from public records. By the cisonews.net Desk.

Henry Schein, the distributor of dental and medical supplies, disclosed on October 16, 2023 that part of its manufacturing and distribution businesses had experienced a cybersecurity incident, determined on October 14. Taking systems offline temporarily disrupted some operations.

First disclosure

The 8-K attached a press release dated October 15. The company said the practice management software its clients use was not disrupted. It had engaged outside experts and notified law enforcement.

November 2 update

A later release announced that the company had filed a notice with the SEC because it needed more time for its third-quarter Form 10-Q, citing the incident and its decision to take down some applications. It said it would discuss the business disruption and recovery costs on its November 13 earnings call.

Not stated in these filings

Neither disclosure describes the attack, gives data findings, or states a cost figure.
