Korn Ferry Completes Acquisition of Hay Group

LOS ANGELES, Dec. 1, 2015 – Korn Ferry (NYSE:KFY), the preeminent global people and organizational advisory firm, today announced that it has completed its acquisition of Hay Group.

Through the talent, capabilities and insights of Hay Group, Korn Ferry now has an unrivaled ability to address the entire talent continuum, a move that affirms the critical role that people and leadership play in driving organizational performance.

“We need a new conversation on people. Never before has there been so much pressure on organizations to succeed. Yet by not applying the same rigor to their people strategy as they do in other areas of their business, organizations largely ignore their greatest lever for success,” said Gary D. Burnison, CEO of Korn Ferry. “We are without question the global leader in the business that enables business – the people business. The combination of our two firms brings together nearly 7,000 talented professionals who have a single purpose – helping leaders, organizations and societies succeed by releasing the full power and potential of people.”

“The Korn Ferry-Hay Group combination marks a historic moment that will reshape the future of work,” said Stephen Kaye, CEO of Hay Group. “This is the perfect combination of two great firms that will be uniquely positioned to help clients achieve their strategic goals and highest aspirations. With more than a century of combined experience, and some of the most prolific people, data and insights in the world, we now have an incomparable capacity to deliver superior results for our clients – ensuring they have the right people, fully aligned, developed and engaged.”

Underpinning Korn Ferry and Hay Group is robust intellectual property and one of the most comprehensive leadership, reward and assessment databases in the world to accelerate client success.

Korn Ferry will serve clients through three business lines – Executive Search, Hay Group (which now includes Korn Ferry’s former Leadership and Talent Consulting segment) and Futurestep:
