Kier acquired Mouchel in June 2015 as it planned to grow in the infrastructure sector.

In its latest results announcement, Kier revealed that it had spent £50m on the integration of Mouchel into the group, resulting in a loss on a statutory basis of £15.4m.

However, Kier also reported that underlying profit from operations of £150m was up 44% thanks to the contribution from Mouchel.

Haydn Mursell, chief executive of Kier, said he was pleased with the results and the completion of the integration of Mouchel.

“We remain focused on growing the business through improving operational efficiencies and investing in new technology to support our operations.

“We believe that our range of complementary businesses underpins the resilience of our operating model and the strength of our order book. 

“Having completed the integration of Mouchel, we are well progressed with the simplification of our portfolio of businesses and are focused on capitalising on the growth opportunities available to the group. 

“We remain confident of achieving our goal of double-digit profit growth on average each year to 2020."

Following the acquisition of Mouchel, Kier hoped to capitalise on the £17bn of investment in the strategic road network to be delivered through Highways England over the next five years.
