Today, VINCI Energies Deutschland Enterprise Solutions AcquiCo SE (the “Bidder”), a wholly-owned indirect subsidiary of VINCI S.A., decided to make a public delisting acquisition offer to the shareholders of ALL FOR ONE GROUP SE (the “Company” or “ALL FOR ONE”) for the acquisition of all non-par value registered shares in the Company not held directly by the Bidder (the “ALL FOR ONE Shares”) against payment of cash consideration in the amount of EUR 67.50 per ALL FOR ONE Share (the “Delisting Offer”). The Delisting Offer will not be subject to any conditions.

The Bidder and the Company signed a delisting agreement today regarding the Delisting Offer according to which the Company has undertaken, subject to a review of the offer document and the management board's and supervisory board's fiduciary duties, to apply for the revocation of the admission of the ALL FOR ONE Shares to trading on the Frankfurt Stock Exchange (Frankfurter Wertpapierbörse) with simultaneous admission to the sub-segment of the regulated market with additional post-admission obligations (Prime Standard) of the Frankfurt Stock Exchange no later than ten banking days prior to the end of the acceptance period of the Delisting Offer with the revocation taking effect (at the earliest) upon the expiration of the acceptance period for the Delisting Offer and, following submission of the delisting application, to take all reasonable measures to terminate the inclusion of the ALL FOR ONE Shares for trading on the open market (Freiverkehr) of any other stock exchange or any other multilateral trading facility or organized trading facility, provided that the inclusion was initiated by the Company.

The Offer Document (in German and a non-binding English translation) which will set forth the detailed terms and conditions of the Delisting Offer, as well as further information relating thereto, will be published by the Bidder following approval by the German Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht) on the internet at the website www.afo-offer.com.

Important notice:

This announcement is for information purposes only and is neither an offer to purchase nor a solicitation of an offer to sell ALL FOR ONE Shares. The final terms of the Delisting Offer as well as other provisions relating to the Delisting Offer will be communicated in the Offer Document after the German Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht) has permitted the publication of the Offer Document. The Bidder reserves the right to deviate from the key items presented here in the final terms and conditions of the Delisting Offer to the extent legally permissible. Investors and holders of ALL FOR ONE Shares are strongly advised to read the Offer Document and all other documents relating to the Delisting Offer as soon as they have been made public, as they will contain important information. The Offer Document for the Delisting Offer (in German and a non-binding English translation) with the detailed terms and conditions and other information on the Delisting Offer will be published after approval by the German Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht), amongst other information, on the internet at www.afo-offer.com.

The Delisting Offer will be implemented exclusively on the basis of the applicable provisions of German law, in particular the German Securities Acquisition and Takeover Act (Wertpapiererwerbs- und Übernahmegesetz – WpÜG), the German Stock Exchange Act (Börsengesetz – BörsG) and certain securities law provisions of the United States of America. The Delisting Offer will not be conducted in accordance with the legal requirements of jurisdictions other than the Federal Republic of Germany or the United States of America (as applicable). Accordingly, no notices, filings, approvals or authorizations for the Delisting Offer have been filed, caused to be filed or granted outside the Federal Republic of Germany or the United States of America (as applicable). Investors and holders of ALL FOR ONE Shares cannot rely on being protected by the investor protection laws of any jurisdiction other than the Federal Republic of Germany or the United States of America (as applicable). This announcement may not be released or otherwise distributed in whole or in part, in any jurisdiction in which the Delisting Offer would be prohibited by applicable law.

The Bidder, its financial advisors and its affiliates reserve the right, to the extent permitted by law, to directly or indirectly acquire additional ALL FOR ONE Shares outside the Delisting Offer on or off the stock exchange, provided that such acquisitions or arrangements to acquire shares will comply with the applicable German statutory provisions and Rule 14e-5 of the Securities Exchange Act of 1934. Information about such purchases will be disclosed in Germany to the extent required by applicable law. To the extent information about such purchases or arrangements to purchase is made public in Germany, such information also will be deemed to be publicly disclosed in the United States. The Delisting Offer announced in this announcement will relate to shares in a German company admitted to trading on the Frankfurt Stock Exchange and will be subject to the disclosure requirements, rules and practices applicable to companies listed in the Federal Republic of Germany, which differ from those of the United States of America and other jurisdictions in certain material respects.
