On April 12, 2021, Amtech Systems, Inc. (together, the “Company,” “we,” “us,” or “our”) detected a data incident in which attackers gained access to and disabled some of the technology systems used by one of our subsidiaries.

Promptly upon its detection of the security event, the Company launched an investigation, engaged legal counsel, and retained incident response and technical professionals.
