The period marked the end of MCI’s five-year plan to triple gross profit between 2006 and 2010 to reach £65m.
MCI said in a statement the growth was an "almost even spilt across corporate and institutional clients and is attributed to global acquisitions (5%) and organic growth mainly in the Asia-Pacific region (8%)".
The company reported a net profit of £2.7m for the year ending December 2010.
It is also benefitting from an £7m investment from Iris Capital this year, set to help reinforce MCI’s position in key growth markets and add new services.
MCI’s acquisitions in 2011 have included Kaizen Eventos in Argentina and Infomed Events in Dubai in February, followed by Avanti Events and Pharma Events in Sydney in April.
MCI Munich was established in March following a merger with EMC Event & Meeting Company.
