While operating profit grew 35% to reach 拢117.2m, reported pre-tax profit shrank 9% to 拢61.9m.
Excluding the impact of the acquisitions, including the March 2014 purchase of Initial Facilities, organic growth was 10%.
Interserve Construction contributed 拢1,178.6m to total group revenues and 拢26.2m operating profit.
The increasingly dominant Support Services side of the business generated 拢1,837.1m in revenues and an operating profit of 拢88.8m.
The operating margin of the UK construction business shrank from 1.8% in 2013 to 1.6% in 2014.
Chief executive Adrian Ringrose said: "2014 was a landmark year for the business in which we advanced our strategy and delivered 35% operating profit growth including strong organic growth despite continuing challenging conditions in a number of our markets. We made two strategic acquisitions (Initial Facilities and the Employment & Skills Group), each of which deepened our presence in core outsourcing markets.
鈥淥ur focus on providing high quality services to both new and existing clients resulted in strong work winning during the year, with our future workload rising 26 per cent to a record 拢8.1 billion.
鈥淟ooking to the future, we are encouraged by the growth potential of the business. Our attractive positioning in our core markets and our ability to identify, invest in and deliver on attractive project and corporate opportunities is a powerful differentiator."聽
