Another private equity firm, Compass Partners, has agreed to make an unspecified investment in Rodenstock. It will act as joint shareholder of the German company next to Bridgepoint, which outbid PAI Partners for the control of Rodenstock in 2006. The details of the transaction could not be learnt at the time of going to press. Bridgepoint had been looking for a new investor or a possible stockmarket flotation for Rodenstock following its recent successful turnaround.
