Carillion plc provides earnings guidance for the year 2016. For the year, the company expects total operating profit to increase as a result of strong revenue growth at a slightly lower operating margin.  The performance continues to be led by revenue growth and a strong margin in support services business segment, which is expected to contribute around two thirds of the Group's total operating profit with this increase more than offsetting the expected reductions in the contributions to underlying operating profit from the sale of equity in Public Private Partnership (PPP) projects and from Middle East construction services. The company do not expect the first-half working capital outflow to be repeated in the second half.  Consequently, the company expects net borrowing at the yearend to be below the £290 million level at 30 June 2016. The company also expect the total value of orders and probable orders won in the second half to be lower than the £2.5 billion in the first half, with the total value of new orders won in the year reaching some £4.5 billion by the year end.  However, the group's total order book plus probable orders at the year end is still expected to be strong at around £16 billion with revenue visibility for 2017 of around 70 %.
