(2) where the advertisement is disseminated in written form by electronic means, including a hyperlink to the prospectus and to the relevant final terms of a base prospectus or by including a hyperlink to the page of the website where the prospectus and any final terms will be published if the prospectus and any final terms have not yet been published; and

(3) where the advertisement is disseminated in a form or by means not falling within the scope of (1) or (2), including accurate information on where the prospectus and any final terms may be obtained, and accurate information on the admission to trading of transferable securities to which it relates.

19/01/2026R

Advertisements in written form, which are disseminated to potential retail investors, must be sufficiently different in format and length from the prospectus that no confusion with the prospectus is possible.

(1) a supplementary prospectus is subsequently published in accordance with PRM 10; and
