AT&S intends to issue a (Hybrid) Convertible Bond and/or a Hybrid Bond; no dividend for the financial year 2025/26

Disclosure of inside information pursuant to Article 17 MAR

THE INFORMATION CONTAINED IN THIS ANNOUNCEMENT IS NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES OF AMERICA, AUSTRALIA, CANADA, JAPAN, THE UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND, SINGAPORE, BELGIUM, FRANCE, ITALY OR IN OR INTO OTHER COUNTRIES IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION MAY BE UNLAWFUL.

Leoben – AT & S Austria Technologie & Systemtechnik Aktiengesellschaft ("AT&S") intends to issue a deeply subordinated perpetual convertible bond with an early redemption option for the company ((Hybrid) Convertible Bond) and/or a deeply subordinated perpetual bond with an early redemption option for the company (Hybrid Bond).

The details of the potential issuance, such as the total nominal value, issue price, conversion price (in case of the (Hybrid) Convertible Bond), time of optional redemption and coupon would be determined based on the market conditions prevailing at the time of the respective issuance.

The combined issue volume of the two financial instruments could amount to up to € 500 million, whereby each of the financial instruments would be limited to a maximum amount of € 400 million. Should the Management Board of AT&S therefore decide to issue only a (Hybrid) Convertible Bond or only a Hybrid Bond, but not both financial instruments, the issue volume would be limited to a maximum of € 400 million.

The (Hybrid) Convertible Bond would be convertible to new ordinary bearer shares of no par value (no-par value shares) of AT&S.

The (Hybrid) Convertible Bond and the Hybrid Bond would be issued at 100% of their nominal value at a denomination of € 100,000 each and would be exclusively directed at institutional investors. Subscription rights to the (Hybrid) Convertible Bond of existing shareholders would be excluded. In this context, reference is also made to the reports of the Management Board of June 2024 and of today. These reports can be accessed on the company’s website at (www.ats.net – https://ats.net/en/ir-news/report-of-the-management-board-of-may-20-2026/).

The company has retained various financial and legal advisors, and the Supervisory Board has given its approval in principle.

The execution of the potential issuances depends in particular on given market conditions and final board resolutions and could take place in the second or third quarter of 2026.

The potential proceeds of the issue would serve for refinancing and would also strengthen the capital base of AT&S.

Furthermore, the Management Board of AT&S decided to propose to the 32^nd Ordinary General Meeting on July 9, 2026 that no dividend be distributed for the financial year 2025/26, as was the case in the previous year.
