Item 7.01 Regulation FD Disclosure.

Minerals Technologies Inc. (the “Company”) today announced that on October 22, 2020, it detected a ransomware attack impacting certain of its information technology systems. Immediately upon its detection of the security incident, which prevented access to certain systems and data within the Company’s network, the company implemented its cyber security emergency response plan. As part of that plan, Company took steps to restore its network and resume normal operations as quickly as possible. The Company launched an investigation working with industry-leading cybersecurity firms, engaged legal counsel, notified law enforcement and is in the process of notifying appropriate governmental authorities.

The network security incident primarily impacted the Company’s internal corporate functions. At the current time and throughout the incident, the Company’s manufacturing sites, which rely on different networks, have continued to operate safely and with limited interruption. Further, the Company currently does not believe that any of its customers or suppliers were impacted as a result of this incident. Nonetheless, the Company believes that the security event included unauthorized access to personal data of employees, former employees and their dependents.

Although the Company is in the early stages of its investigation and assessment of the incident, based on the preliminary data obtained from the assessment and on the information currently known, the Company does not currently believe the incident will have a material impact on its business, operations or financial results.
