Breedon Group plc is a British construction materials company which has its headquarters at Breedon on the Hill, Leicestershire, England. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index. Breedon was traditionally centered around the quarrying of stone at Breedon on the Hill since the late 1800s. During 2000, Breedon was purchased by the Midlands-based aggregates firm Ennstone. In 2009, Ennstone entered administration and was acquired by the investment company Marwyn Materials, after which the firm was reorganised into Breedon Aggregates. Throughout the early 2010s, Breedon completed numerous acquisitions, both of whole companies and assets of larger competitors, such as Aggregate Industries and Marshalls plc. In 2016, the firm was cleared by the Competition and Markets Authority to complete its purchase of Hope Construction Materials. Two years later, CMA also cleared a complex transaction between Breedon and rival firm Tarmac under which numerous plants, quarries, and cash were exchanged. Wikipedia
