Merger Plan with Topotarget: Pre-approval for the secondary listing of the shares of the merged company on NASDAQ OMX Copenhagen

BioAlliance Pharma SA (Euronext Paris – BIO), an innovative company specialized in the development of drugs in orphan oncology diseases, today announces that it has received a pre-approval from NASDAQ OMX Copenhagen for the secondary listing and admission to trading on NASDAQ OMX Copenhagen of the shares of BioAlliance Pharma SA, subject to completion of the merger of Topotarget and BioAlliance Pharma, resulting in the creation of Onxeo.

Onxeo aims at becoming a global leader on the fast-growing market of orphan oncology drugs. It will hold a complementary portfolio of advanced programs targeting severe pathologies for which there is an unmet medical need. Onxeo will offer reinforced market attractiveness, notably towards specialized international investors, through a more important critical mass, a European scale and a high added value product portfolio.

The merger will be submitted to the vote of Topotarget and BioAlliance Pharma shareholders, respectively on June 27, 2014 and on June 30, 2014.

Once the merger is completed and subject to the renewed approval by NASDAQ OMX, the shares of Onxeo will be listed on both Euronext Paris and NASDAQ OMX Copenhagen stock markets in order to allow Topotarget shareholders, who will become Onxeo shareholders, to remain able to trade their Onxeo shares on the Danish stock market. The shares of the merged company will be identified with the ticker “ONXEO” on Euronext Paris and NASDAQ OMX Copenhagen stock markets.
