CELSIS, the product testing company for the cosmetics, food and pharmaceutical industries, yesterday agreed to a £54.5m takeover bid from the activist investor Christopher Mills.<br /><br />Mills is bidding on behalf of a newly-created investment fund Nastor Investments. Nastor is controlled by funds managed by North Atlantic Value, which has total funds under management of about £506m. Mills has been buying shares in Celsis since October of last year, helping boost its share price and keep it at a level higher than it otherwise would have been.<br /><br />Commenting on the offer, Mills said: “We believe that Celsis is a good company with strong operational management. Yet the costs that it incurs in being publicly listed are relatively high for a company of its size. Therefore, we believe it will benefit from going forward as a private entity.”<br /><br />He added: “We look forward to supporting the company in a more cost effective corporate structure.”<br /><br />The bid price of 232.5p a share is 14.3 per cent higher than the closing price of Celsis on Friday.<br /><br />Mills is a founding director of JO Hambro Capital Management.
