Carillion plc provided group earnings guidance for the first-half ended June 30, 2017 and revised group earnings guidance for the full year 2017. For the first half of 2017, revenue is expected to be similar to that in 2016 at approximately GBP 2.5 billion. In its trading update, the company announced its operating profit would be lower than expectations primarily due to phasing of Public Private Partnerships equity disposals, which are now expected to be in the second half. Net debt at 30 June was expected to be around GBP 575 million, and adjusted net debt, which excludes the impact of the net derivate asset mainly relating to the company's U.S. private placement loans, is expected to be GBP 536 million. The company revised guidance for full year 2017. For the year, the company expects group revenue to be between GBP 4.8 billion and GBP 5 billion with underlying operating profit around 15% to 20% lower than 2016. Excluding disposals, the company expects net debt at the year-end to be slightly lower than at the half year with the full year average between GBP 775 million and GBP 800 million.
