Green Development Notes 3 due 2030 EUR (XS2974122132)
(the Notes)

issued by the securitisation fund Telekia,

acting through the Management Company
in respect of its Compartment 3 (the Issuer)

We refer to the terms and conditions in respect of the Notes (the Conditions). Capitalised terms used in this notice but not defined herein shall have the meaning given to them in the Conditions.

Delisting from the Frankfurt Stock Exchange (Open Market)

The Issuer hereby informs the Noteholders that, following consultation with its listing agent and the Reference Portfolio Advisor of the notional Reference Portfolio, the Issuer resolved to apply for a delisting of the Notes from the Open Market (Freiverkehr) of the Frankfurt Stock Exchange.

The Issuer takes the view that it will no longer be able to comply with the Frankfurt Stock Exchange's liquidity requirements for a listing of the Notes due to its persistently low liquidity and the anticipated lack of inflows from the Reference Portfolio Components in the short to medium term.

This disclosure is made in accordance with the Issuer's obligations under Article 17 of Regulation (EU) No 596/2014 (MAR).

The Issuer further informs the Noteholders that the Notes continue to be transferable and that the Calculation Agent of the Notes under normal market conditions will determine indicative valuations for information purposes based on information available to the Calculation Agent.

These indicative valuations of the Notes are available on a quarterly basis

• on the website of the Issuer: https://telekia.lu/
• on the website of the Calculation Agent: https://oaklet.de/

However, as there is no guaranteed buyer, Noteholders should be prepared to remain invested until the relevant Maturity Date of the Notes.
