UBM Development AG: Successful exchange of two UBM bonds with a participation rate in total of 45%

Wien (pta024/17.10.2025/12:00 UTC+2)

• Around €121 million of the two UBM bonds 2019–2025 and 2021–2026 were exchanged into the current green UBM bonds
• The subscription period for the cash offer of the new 6.75% UBM Green Bond 2025–2030 (AT0000A3PGY9) starts on Monday, 20 October 2025 – early closing possible
• The price was set at 100%

Vienna, 17.10.2025 – On 16 October 2025, the second exchange offer for the UBM bond 2019–2025 with an original volume of €120 million and for the UBM bond 2021–2026 with an original volume of €150 million ended. After €74 million of these two bonds had already been exchanged and thereby extended in October 2024, the current offer accounted for an additional €48 million. In total, around €121 million of the original bond volume of €270 million was exchanged. This corresponds to a remarkable exchange rate of 45%, which is at the upper end of historically achieved levels.

On Monday, 20 October 2025, the subscription period for the new 6.75% UBM Green Bond 2025–2030 (AT0000A3PGY9) with a term of five years will begin.

The cash subscription offer was preceded by an exchange offer to the holders of the UBM bond 2019–2025 and the UBM bond 2021–2026, allowing them to exchange their bonds for the new five-year UBM Green Bond 2025. In the second exchange round, approximately one quarter of the holders accepted the offer. As a result, a total nominal amount of precisely €47.67 million from the most recent exchange was converted. The exchange period ended on 16 October 2025.

The re-offer price was set by the issuer, in coordination with the joint lead managers, at 100.00%.

Interested investors will likely be able to subscribe to the 6.75% UBM Green Bond 2025–2030 between 20 October and 24 October 2025. However, an early closing of the offer is likely, and therefore an early end to the subscription period remains reserved. The UBM Green Bond 2025 will be offered for subscription to the public in Austria, Germany and Luxembourg under a prospectus, and in other countries through a private placement. The expected value date is 30 October 2025. Admission of the UBM Green Bond 2025 to trading on the Official Market (Corporates Prime) of the Vienna Stock Exchange and its inclusion in the Open Market segment of the Frankfurt Stock Exchange is intended.
