Temasek, the Singapore sovereign wealth fund, is working alongside WuXi PharmaTech's [NYSE WX] Chairman Ge Li, Ally Bridge and Boyu Capital to take the pharmaceutical services company private, two sources and a person familiar with the situation said. One of the sources said other parties are in talks to join the consortium. The second source said public announcements regarding the proposed indicative USD 46 per share offer are expected "very soon". The indicative offer was first revealed on 30 April. The inclusion of Temasek comes after Boyu Capital joined original buyout consortium members Ge Li, who owns 1.4% of WuXi, and Ally Bridge, a global healthcare investment group led by Frank Yu, formerly an MD at Goldman Sachs and Och-Ziff. The 30 April announcement said additional equity investors could join the consortium, which intends to finance the acquisition via debt and equity capital.
