Navigant Announces Agreement with Engine Capital

Targets Return of $175 Million Through Share Repurchase Program by the End of 2020

CHICAGO—May [X], 2018— Navigant (NYSE: NCI) today announced that it has entered into an agreement with Engine Capital, L.P. (“Engine Capital”) to end its current proxy contest. As part of the agreement, the Board has approved an expansion of the Company’s share repurchase authorization to $175 million and will target repurchasing shares in that amount by the end of 2020 as part of a longer-term capital return program. The authorization replaces the previous share repurchase authorization under which approximately $52 million remained as of March 31, 2018. Engine Capital has agreed to withdraw its slate of director nominees for election at the 2018 Annual Meeting of Shareholders, to vote for all of Navigant’s director nominees, and to customary standstill and related provisions.

“Today’s announcement reflects our continued confidence in the strength of our free cash flow generation and further reinforces our ongoing commitment to return capital to shareholders,” said Julie Howard, chairman and CEO of Navigant. “In making the decision to expand our repurchase authorization to further enhance shareholder value, the Board considered the interests of all of our shareholders, including recent input the Board received from some of our larger shareholders.”

“We appreciate the constructive dialogue we have had with Ms. Howard and the Board. Over the last few months, Navigant has taken a number of shareholder-friendly steps, including refreshment of its Board. Today’s announcement represents another step in the right direction. We believe the Company is now well-positioned to execute on its plan and enhance shareholder value,” said Arnaud Ajdler, Managing Member of Engine Capital.

The complete agreement between Navigant and Engine Capital will be included as an exhibit to the Company’s Current Report on Form 8-K, which will be filed with the Securities and Exchange Commission (“SEC”).
