Ad-hoc notification pursuant to Article 17 of the Market-Abuse-Regulation (EU) No. 596/2014

ADVA Optical Networking SE: ADVA is applying for a segment change to the General Standard of the regulated market of Deutsche Börse

Munich, Germany, 18 April 2023.

Today, the management board of ADVA Optical Networking SE ("ADVA") has decided to file an application for the revocation of the admission of its shares to the Prime Standard of the Frankfurt Stock Exchange. The admission of the ADVA shares to the regulated market (General Standard) remains unaffected. The segment change and the associated discontinuation of the extended post-admission reporting obligations are intended to reduce complexity and cost.

The change to the General Standard will take effect three months after the publication of the revocation decision by the management of the Frankfurt Stock Exchange on the website of the German Stock Exchange (www.deutsche-boerse.com).
