Privately held IMG represents athletes like Tiger Woods and Peyton Manning, in addition to units focused on licensing, events and programming. It has 3,000 employees across 30 countries.
Bret Werner, managing partner at Catalyst, said the firm has enjoyed a "strong and productive" relationship with IMG for several years.
IMG sports and entertainment group president George Pyne said the deal is part of a plan to expand IMG's portfolio into key marketing services around the world. "We plan to integrate their capabilities into our global Consulting practice that includes our fast growing PR services in the UK and expand these communications services into key markets in Europe, Middle East, South America and Asia," he said. "They will also be able to work with other IMG Divisions where these types of corporate partner communication services are needed."
Catalyst's management team and staff from New York, Charlotte and L.A. are all slated to join IMG Consulting, its division focused on advertising, PR, digital and marketing.
