Andover, Mass., February 13, 2023 — MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of enabling technologies that transform our world, today reported that due to the ransomware event that was identified on February 3, 2023, the Company now plans to release fourth quarter and full year 2022 financial results after market close on Monday, February 27, 2023 and host a conference call with management on Tuesday, February 28, 2023 at 8:30 a.m. (Eastern Time).
Upon learning of the ransomware event, MKS took immediate action to contain the incident and has initiated the recovery phase. MKS continues to work diligently to restore operations at affected facilities. The ransomware event has had a material impact in the first quarter on the Company’s ability to process orders, ship products and provide service to customers in the Company’s Vacuum Solutions and Photonics Solutions Divisions. 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.
By postponing the timing of the release of financial results, the Company expects to be in a better position to address the financial impact of the ransomware event.
