Johnston Quarry Group has been acquired by SigmaRoc
The shareholders of Johnston Quarry Group Ltd have sold the company to SigmaRoc PLC.
Johnston Quarry Group is a specialist quarried materials supplier producing construction aggregates and premium quality building stone. The Group operates eight quarries and two separate processing sites in the UK, located across the Southwest, Oxfordshire and Lincolnshire.
SigmaRoc is an AIM-quoted buy-and-build group targeting construction materials assets in the UK and Northern Europe. The acquisition will extend SigmaRoc’s footprint in the UK and increase market coverage.
Oaklins Smith & Williamson, based in the UK, was the exclusive corporate finance advisor to the shareholders, following an off-market approach from the buyer.
