Munich, 21 June 2017 - Tiancheng (Germany) Pharmaceutical Holdings AG, a company indirectly controlled by Creat Group Corporation, ("Bidder"), announced the start of the mandatory additional acceptance period for its voluntary takeover offer for all outstanding shares in Biotest AG ("Biotest"). After the required minimum acceptance threshold of at least 75% of all Biotest ordinary shares has been crossed, the additional acceptance period provides all remaining shareholders of Biotest with the opportunity to tender their shares and realize an attractive valuation.

As outlined in the offer document, the Bidder offers Biotest shareholders EUR28.50 per Biotest ordinary share and EUR19.00 per Biotest preference share in cash. The offer has been strongly and repeatedly recommended by the Biotest Management and Supervisory Board.

Mr Wu Xu, CEO of Creat, said: "With more than 75% of Biotest ordinary shares having been tendered, we have reached an important milestone. We are encouraged by the large majority of Biotest ordinary shareholders who have already seized this unique opportunity and accepted our offer. To help secure Biotest's long-term future, we invite all remaining ordinary and preference shareholders to accept the offer in the additional acceptance period in line with the Biotest Management and Supervisory Boards' recommendation."

Shareholders who have not yet accepted the offer can still tender their shares to the Bidder at unchanged terms until the end of the additional acceptance period on 4 July 2017 at 24:00 hrs (Frankfurt am Main local time)/18:00 hrs (New York local time).
