Clarion Events

Clarion Events organizes trade shows, conferences and media brands. The business traces back to 1947 as the events arm of Earls Court & Olympia; its legal entity, Clarion Events Limited, was incorporated in 1948. A management buyout in 2004 was followed by investment from Providence in 2015 and a sale to Blackstone funds in 2017. On October 6, 2026, Informa agreed to buy Clarion for an enterprise value of £2.24bn, with completion expected in the fourth quarter of 2026, subject to regulatory approval.

The company says it runs more than 125 brands with 1.2 million attendees and 47,000 exhibitors a year in 25 countries, and employs about 2,000 people. Lisa Hannant is CEO and Russell Wilcox is Executive Chairman. Its headquarters are at Fulham Green in London, with offices in Berlin, Hong Kong, Shanghai, Jakarta, Maarssen, Singapore, Cape Town and Shelton, Connecticut.

Affiliate Summit, with Affiliate Summit West in Las Vegas and Affiliate Summit East in New York, has been part of Clarion since July 2017; Creator Economy Live runs alongside the West edition. Clarion's gaming division, Clarion Gaming, renamed itself WorldGaming in January 2026 and organizes ICE Barcelona, iGB Affiliate, iGB L!VE and the Casino & Sportsbook and PFC leaders' summits.
