Bison Capital Acquisition Corp. and Xynomic Pharmaceuticals, Inc.

Announce Signing of Definitive Merger Agreement

NEW YORK, NY and SHANGHAI, China, September 12, 2018 (PR Newswire)  

Bison Capital Acquisition Corp. (“BCAC”, NASDAQ: BCAC) and Xynomic Pharmaceuticals, Inc. (“Xynomic”), a U.S.-China clinical stage innovative oncology drug development company, today jointly announced that they have signed a definitive merger agreement. Upon completion of the merger, Xynomic will become a wholly-owned subsidiary and the operating business of BCAC, and BCAC will change its name to “Xynomic Pharmaceuticals Holdings, Inc.”

Xynomic, founded in 2016 by industry veterans and headquartered in the U.S. with operations in Raleigh, North Carolina and Shanghai, China, is principally engaged in the research, development and commercialization of innovative targeted cancer therapeutics in the U.S., Europe and China. Xynomic has in-licensed a clinical stage drug candidate from Pharmacyclics/AbbVie and a pre-clinical stage drug candidate from Boehringer Ingelheim and is collaborating with Janssen R&D, LLC in a clinical trial of a combination therapy. Xynomic focuses on orally delivered small molecule drugs. Xynomic builds and develops its oncology pipeline through both in-licensing from strategic partners and internal research and development efforts supported by its scientists with expertise in tyrosine kinase inhibition and epigenetic modification. The current investors of Xynomic include, among others, Northern Light Venture Capital, Prosperico Ventures and Hakim Unique.

Dr. James J. Tong, Chief Executive Officer and Executive Director of BCAC, remarked, “We are truly excited about the merger with Xynomic. Our team reviewed many opportunities in a variety of industries, and determined that the transaction with Xynomic would provide the greatest value to our shareholders. Xynomic is developing promising oncology therapeutics to address unmet medical needs. We are impressed by the Xynomic management team’s track record in drug development and partnership building. We are very excited about the future prospects of the combined company.”

Y. Mark Xu, Founder, Chairman, Chief Executive Officer and President of Xynomic, stated, “We believe that merging with BCAC and becoming a Nasdaq-listed company will potentially provide us with access to more capital allowing Xynomic to develop and commercialize innovative oncology drugs faster, transform innovations into commercially viable drugs to meet significant unmet medical needs more efficiently, and better motivate our highly skilled and professional team.”

Transaction Details

Under the terms of the merger agreement, BCAC will re-domesticate from the British Virgin Islands to Delaware prior to the merger. At closing, Xynomic will merge with and into Bison Capital Merger Sub Inc., a wholly owned subsidiary of BCAC, with Xynomic continuing as the surviving company. At the effective time of the merger, existing common and preferred shareholders of Xynomic will receive shares of common stock of BCAC. The aggregate merger consideration will consist of (a) closing consideration of $350 million in BCAC shares, subject to certain adjustments as provided in the merger agreement, and (b) earnout consideration of an additional $100 million in BCAC shares, subject to Xynomic achieving certain milestones as set forth in the merger agreement. Merger consideration will be payable entirely in common stock of BCAC at a value of $10.15 per share. Three percent of the initial BCAC shares payable to Xynomic shareholders in the merger and three percent of the earnout shares, when payable, will be held in escrow for a period of 18 months following the closing to serve as security for, and the exclusive source of payment of, BCAC’s indemnity rights under the merger agreement and any excess of the estimated closing merger consideration over the final closing merger consideration amount determined post-closing.

The board of directors of BCAC at closing will consist of nine directors, one of which will be a current director of BCAC, three of which will be current directors of Xynomic, and two of which will be independent directors mutually agreed upon by BCAC and Xynomic, in addition to the current three independent directors of BCAC. The executives of Xynomic are expected to remain as executives of the combined company.

The closing conditions of the merger include, among others, the approval of the merger by BCAC’s existing shareholders, the approval of the continued listing of the combined entity on The Nasdaq Capital Market and BCAC having at least $7,500,001 of net tangible assets remaining at the closing.

Upon and immediately following the consummation of the merger, assuming that there is no adjustment to the closing consideration and no exercise of redemption rights by BCAC’s public shareholders, it is anticipated that, without the earnout shares, the shareholders of Xynomic prior to the closing will collectively own approximately 80% of outstanding common stock of the combined entity, and BCAC’s existing shareholders will retain approximately 20% ownership interest in the combined entity.

EarlyBirdCapital, Inc. is acting as financial advisor to BCAC, and Cassel Salpeter & Co., LLC is acting as financial advisor to the special committee of BCAC’s board. Hunter Taubman Fischer & Li LLC and Ogier are acting as legal counsels to BCAC. Sidley Austin LLP is acting as legal counsel to Xynomic.

The description of the transaction contained herein is only a summary and is qualified in its entirety by reference to the definitive agreement relating to the transaction, a copy of which will be filed by BCAC with the Securities and Exchange Commission (the “SEC”) as an exhibit to a Current Report on Form 8-K.
