Henry Boot expects its performance for the year ending 31 Dec to be materially ahead of the board's existing forecasts.
The group said that trading since the interim results announcement on 25 Aug had continued to be very strong across all its business segments, in particular, within property development and land promotion.
It said: 'Given the accelerated completion of transactions in September and October 2017, and the successful delivery of major development schemes through the second half of the year, we anticipate that the group's performance for the year ending 31 Dec 2017 will be materially ahead of the board's existing expectations.
'2017 has proved to be an outstanding year where almost every deal we hoped to complete has done so.
'Furthermore, we concluded several deals in 2017, earlier than we had originally anticipated, including the sale of the final 30,500 sq ft industrial unit at Thorne, the sale of an 8,150 sq ft retail park in Monmouth and 80 residential units on land in Prestonpans.
' In addition, the delivery of several industrial units at Markham Vale has, once again, been quicker than forecast.'
