Balfour Beatty shares reached a record high today as it nudged its annual profit forecasts higher.

It came as the FTSE 250 construction firm reported strong demand for infrastructure projects on both sides of the Atlantic in the first half of the year.

A strong showing across its core earnings businesses means it now expects ‘low double-digit percentage growth’ from its operating businesses, having previously guided ‘high single-digit percentage growth’.

Shares gained 8.4 per cent to 938.5p, having gained 31.4 per cent this year.

Balfour Beatty, which works on public and private sector projects across the transport, energy and defence sectors, reported underlying profit from operations of £153million for the first half of the year, compared with £108million a year earlier.
