The group saw its underlying pre-tax profits increase to £38 million in the first six months of the year, up 8.9 per cent from £34.9 million in the same period last year.
Aegis, which is home to the media buying networks Carat and Vizeum, increased its digital revenue from 13 per cent to 19 per cent during the first half of the year against the same period last year.
It also set a new-business record of $1.3 billion. New-business wins included the combined £160 million Adidas and Reebok global media planning and buying business, won by Carat in May.
Robert Lerwill, the chief executive of Aegis Media, said: "Our worldwide appoint-ment by Adidas-Reebok shows the value of our investment in digital and communications planning, putting us in place to get to important consumer groups such as the hard-to-reach 17-year-old."
Synovate, the Aegis-owned market research division, also put in a strong performance, increasing orders period on period by 13 per cent.
