Effective February 12, 2018, the Board of Directors (the “Board”) of Navigant Consulting, Inc. (the “Company”) increased the size of the Board from nine to ten directors, and appointed Jeffrey W. Yingling as a director to fill the resulting vacancy until the Company’s 2018 Annual Meeting of Shareholders and until his successor is elected and qualified or until his earlier resignation, retirement or removal. Mr. Yingling will serve on the Audit Committee of the Board. Mr. Yingling will be compensated for his service in the same manner as the Company’s other non-employee directors. For a description of the Company’s director compensation program, see the section titled “Director Compensation” in the Company’s proxy statement for the 2017 Annual Meeting of Shareholders, filed with the Securities and Exchange Commission on April 10, 2017.

There are no arrangements or understandings between Mr. Yingling and any other person pursuant to which he was selected as a director of the Company. There are no transactions in which Mr. Yingling has an interest requiring disclosure under Item 404(a) of Regulation S-K. The Board has determined that Mr. Yingling has no material relationship with the Company and is otherwise independent for purposes of the Listed Company Manual of the New York Stock Exchange (“NYSE”) and the Company’s categorical standards for director independence. In addition, the Board has determined that Mr. Yingling meets the NYSE’s financial literacy requirements and satisfies the criteria for being an “audit committee financial expert” as set forth in the applicable rules and regulations of the Securities and Exchange Commission, as promulgated under the Sarbanes-Oxley Act of 2002.

A copy of the press release announcing Mr. Yingling’s appointment as a director of the Company is attached hereto as Exhibit 99.1.
