Consort Medical has reaffirmed that it believes that the purchase of AIM-quoted Advanced Medical Solutions "has strong strategic and commercial logic".Medical devices and drug delivery products supplier Consort revealed its interest in AMS last week but the management of the wound care company refuses to enter discussions. It has also blocked Consort's attempt to carry out due diligence. Consort says that any offer for AMS is dependent on due diligence being carried out, the unanimous and unqualified recommendation for the bid from the board and the directors' acceptance of the bid. A bid also depends on Consort obtaining the finance to pay for it. Consort does say that it could waive any of these pre-conditions.
