Disclosure of an inside information acc. to Article 17 paragraph 1 of the Regulation (EU) No. 596/2014 (Market Abuse Regulation - MAR) Ad-hoc: Centrotec Sustainable AG resolves on public share buyback offer for up to 1,764,652 shares Brilon, Germany, May 11, 2018 - The management board of Centrotec Sustainable AG (ISIN DE0005407506 / WKN 540750) resolved today, with the approval of the supervisory board, to purchase up to 1,764,652 shares of the company (corresponding to a maximum of up to 9.79 % of the company's current share capital) by means of a voluntary public share buyback offer against payment of an offer price in the amount of EUR 14,40 per no-par value share. With this public share buy-back offer, the management board makes use of the authorization granted by the general meeting on May 20, 2015 in accordance with Sect. 71 para. 1 item 8 of the German Stock Corporation Act (Aktiengesetz) to acquire own shares. With this share buyback, the management board pursues a balanced use of the comparatively high, freely available cash resources, which will therefore in part benefit the shareholders of Centrotec. The management board intends to cancel the acquired treasury shares. The offer period will commence on May 22, 2018, 00:00 (CEST) and is expected to end on June 12, 2018, 24:00 (CEST). If more than 1,764,652 shares are tendered for buyback under this buyback offer, the declarations of acceptance will be considered proportionally, i.e. in the ratio of the tendered shares (tender ratio). Further details on the public share buyback offer and its settlement can be taken from the offer document, which will be published on the company's website (www.centrotec.com) in the section "Investor Relations - Share Buyback" on May, 14, 2018, as well as subsequently in the German Federal Gazette under www.bundesanzeiger.de.
