Following this transaction and in conformity with the provisions of the Transparency Directive, the Company hereby notifies the market that the total number of Ordinary shares that the Company has in issue, less the total number of Ordinary shares bought back for cancellation by the Company following such purchase, and therefore, the total number of voting rights in the Company is 41,158,682.
