(38)The EU Follow-on prospectus and the EU Growth issuance prospectus should complement the standard prospectus in Regulation (EU) 2017/1129. Therefore, unless expressly stated otherwise, all references to ‘prospectus’ under Regulation (EU) 2017/1129 are to be understood as referring to all different forms of prospectuses, including the EU Follow-on prospectus and the EU Growth issuance prospectus. The voluntary nature of the prospectus types means that an issuer is permitted to choose one from among the prospectus types available when an offer to the public or admission to trading on a regulated market requires a prospectus.
