The Munich traffic technology specialist Schaltbau is about to be taken over by the US financial investor Carlyle. Carlyle announced an offer of 53.50 euros per share, which is 32 percent above the closing price on Friday. That corresponds to an enterprise value of 709 million euros. Carlyle has already secured 69 percent of the shares through commitments from previous shareholders. The Schaltbau board wants to support the offer. Carlyle has promised that the existing structure and locations of the Schaltbau Group and its workforce will be retained.
