Article 21(7) to (11) of the Prospectus Regulation provides for further requirements for publication:
Article 21
Publication of the prospectus
…
7. All prospectuses approved shall remain publicly available in electronic form for at least 10 years after their publication on the websites referred to in paragraph 2.
Where hyperlinks are used for information incorporated by reference in the prospectus, and the supplements and/or final terms related to the prospectus, such hyperlinks shall be functional for the period referred to in the first subparagraph.
8. An approved prospectus shall contain a prominent warning stating when the validity of the prospectus will expire. The warning shall also state that the obligation to supplement a prospectus in the event of significant new factors, material mistakes or material inaccuracies does not apply when a prospectus is no longer valid.
9. In the case of a prospectus comprising several documents and/or incorporating information by reference, the documents and information that constitute the prospectus may be published and distributed separately provided that those documents are made available to the public in accordance with paragraph 2. Where a prospectus consists of separate documents in accordance with Article 10, each of those constituent documents, except for documents incorporated by reference, shall indicate that it is only one part of the prospectus and where the other constituent documents may be obtained.
10. The text and the format of the prospectus, and any supplement to the prospectus made available to the public, shall at all times be identical to the original version approved by the competent authority.
11. A copy of the prospectus on a durable medium shall be delivered to any potential investor, upon request and free of charge, by the issuer, the offeror, the person asking for admission to trading on a regulated market or the financial intermediaries placing or selling the securities. In the event that a potential investor makes a specific demand for a paper copy, the issuer, the offeror, the person asking for admission to trading on a regulated market or a financial intermediary placing or selling the securities shall deliver a printed version of the prospectus. Delivery shall be limited to jurisdictions in which the offer of securities to the public is made.
