Corona case at AIXTRON - No restrictions on business operations

Herzogenrath/Germany, 28 February, 2020 - AIXTRON SE (FSE: AIXA), a worldwide leading provider of deposition equipment to the semiconductor industry, reports a Corona case at its headquarters in Herzogenrath, Germany.

In the evening of February 27, 2020, AIXTRON was informed by an employee that he had been tested positive for the novel Corona virus.

The case is related to the already known COVID-19 cases in the district of Heinsberg, Germany and the colleague is being looked after by the local district health authority.

The employee works in a restricted, demarcated area, was only in the company for 3 days between the infection and the beginning of his vacation and therefore had contact with only very few colleagues.

The employee's chain of contact was identified yesterday. All colleagues who were in contact with him (Category I and II) have been informed and have been instructed to stay at home.

For the protection of all employees, the affected work area is professionally disinfected. In addition to the already existing protective measures for all colleagues at the site, expanded protective measures in the area of hygiene and employee behavior were immediately put into effect.

AIXTRON's business operations continue without restriction.
