Events revenue fell to £287.5m (from £291.8m) according to the firm's full-year results.
UBM chief executive officer David Levin said: "Our events business traded well in 2009, contributing more than half our adjusted operating profits and demonstrating the growing importance of market-leading, face-to-face events in the digital age."
"Our large tradeshows fared particularly well, with our top 20 annual events - which contribute around half of our events revenue and more than two thirds of our events-adjusted operating profits - growing by nearly 12%."
More negatively, forward bookings for UBM's top 20 annual events due to run over the next 12 months are currently 1.7% below last year's level.
Separately, the firm has acquired E Commerce Expo on behalf of its UBM Live division, for an initial cash consideration of £600,000 and a deferred amount dependent upon future financial performance. The deal for the Olympia-based show also incorporates Manchester-based E Commerce Expo North.
The group saw overall revenue fall from £887m in 2008 to £847.6m in 2009.
