Asterand plc - Board Changes

July 29, 2011 -- The Company today announces that Martyn Coombs has decided to step down as Chief Executive Officer, with immediate effect.

Martyn has been responsible for guiding the Company though an exciting period in its development, including the acquisition of BioSeek in 2010 which has added significantly to the Company’s growth prospects.

The Company has immediately commissioned a search process for the new CEO. In the meantime Jack Davis, the Company’s Chairman, will take over the role of Interim CEO.

Jack Davis, the Chairman and Interim CEO, said: “Martyn has been a positive influence as CEO over the last four years and we wish him well for the future.”

The Company continues to experience the trading patterns described in the IMS on 17 May 2011 and, not withstanding the historical weighting towards the second half, the Board remains confident in achieving market expectations for the year as a whole.
