Evanta produced adjusted operating profit in the year to 2nd October 2011 (before amortisation and impairment charges) of £5 million on revenues of £16 million.
On completion, DMGT expects to use the final net cash proceeds to reduce debt.
Martin Morgan (pictured), Chief Executive of DMGT, said: "We continue to actively manage our portfolio. The sale of Evanta is another good example of how DMGT is focusing its financial and talent resources. We are committed to further expanding our fast growing events businesses operating in the energy and digital marketing sectors and those located in the Middle East region".
