The London-based company has sought to shore up cash and profitability in its home market as the infrastructure sector gets fewer contracts since the country voted to leave the European Union.

However, a survey showed last week that the pace of decline in British construction eased in November but the sector remained a long way from a return to growth on Brexit and election uncertainty.

Balfour, which has a small presence in Hong Kong, said its operations had not been impacted by the civil unrest.

The infrastructure giant now expects annual cash to be around 310 million pounds ($397.73 million), higher than the range of 280 million to 300 million pounds it forecast earlier.

Annual revenue is seen rising about 5% compared with last year, while the year-end order book is expected to be in excess of 14 billion pounds.

Shares of the company opened 4% higher on the London Stock Exchange.
