Carlyle to buy airfield lighting group ADB Safegate

Buyout group Carlyle has agreed to buy airfield lighting group ADB Safegate at a valuation of about ^900 million ($1 billion) including debt, sources said. ADB Safegate supplies visual guidance solutions from landing to parking for airplanes, including lighting systems for airport runways as well as docking and tower systems. PAI Partners bought ADB from investor Montagu in 2013 for ^208 million and last year acquired docking guidance systems specialist Safegate International for an undisclosed sum.
