On February 13, 2023, MKS Instruments, Inc. (the “Company”) issued a press release that included additional information on the ransomware event the Company had previously disclosed in a Current Report on Form 8-K filed on February 6, 2023.

The incident has not impacted the operations of the Company’s Materials Solutions Division. The full scope of the costs and related impacts of this incident, including the extent to which the Company’s cybersecurity insurance may offset some of these costs, has not been determined.
