Keller Group plc

Sale of Property

Keller Group plc ("Keller" or "the Group"), the world's largest geotechnical contractor, announces that it has sold the freehold of a processing and warehousing facility at Avonmouth, near Bristol, to CSUK1 Holdings Limited and CSUK1 Investments Limited for a cash consideration of £62m.

As previously announced, Keller acquired the property in May 2016 pursuant to a settlement agreement in connection with a contract dispute arising on a project completed in 2008. Since that time, the Group has received around £4m of rental income, which has been treated as an exceptional item.

Most of the proceeds will be used to repay the £48m bank facility raised for the original acquisition of the property.

The property is held on the Group's balance sheet at a value of £54m. The sale therefore realises a profit of £8m before costs which will be included as an exceptional profit in the Group's 2017 interim results.
