ASML Holding NV said Wednesday that it has experienced an unauthorized misappropriation of data relating to proprietary technology by a former employee in China, but that it believes the misappropriation isn't material to the business.

The Dutch semiconductor-equipment maker said in its annual report that a comprehensive internal review was initiated, but based on initial findings it doesn't think the incident was material.

As a result of the security incident, certain export control regulations might have been violated, it said.

ASML reported the incident to the relevant authorities, it added.

"We are implementing additional remedial measures in light of this incident," the company said.

The company also said it is experiencing an increasing number of cyberattacks on its IT systems. Attacks include malicious software, or malware, attempts and acts to gain unauthorized access to data and other electronic and physical security breaches of systems.
