Navigant Consulting 8-K Completion of Acquisition or Disposition of Assets

Exhibit 99.1

Unaudited Pro Forma Condensed Consolidated Financial Information

On June 23, 2018, Navigant Consulting, Inc. (the “Company” or “Navigant”) entered into an Equity Purchase Agreement (as amended, the “Purchase Agreement”), with Ankura Consulting Group, LLC (“Ankura”) and its subsidiary Ankura Consulting Worldwide, Inc. (“Worldwide” and together with Ankura, the “Buyer”), pursuant to which, among other things, Navigant agreed to sell its Disputes, Forensics and Legal Technology segment and Transaction Advisory Services practice (the “Business”) to the Buyer (the transactions described in the Purchase Agreement, together, referred to as the “Disposition”). On August 24, 2018, the Company completed the previously announced Disposition, which constituted a significant disposition for purposes of Item 2.01 of the Current Report on Form8-K of the Company dated as of August 30, 2018 relating to the closing of the Disposition (the “Navigant ClosingForm 8-K”).

The accompanying unaudited pro forma financial information should be read in conjunction with the Company’s historical consolidated financial statements and the accompanying notes included in the Quarterly Report on Form10-Q for the six months ended June 30, 2018 filed with the Securities and Exchange Commission (the “SEC”) on August 7, 2018 (“2018 Q2 10Q”).

Based on its magnitude, the Disposition represents a significant shift that has a material effect on the operations and financial results of the Company. Accordingly, the Business qualified for discontinued operations treatment as of June 30, 2018, as required by Accounting Standards Codification205-20 and the assets and liabilities of the Business qualified as assets and liabilities held for sale for the same period. This presentation was reflected in the Company’s unaudited consolidated statements of income for the six months ended June 30, 2018, and the unaudited consolidated balance sheets of the Company as of six months ended June 30, 2018 and the year ended December 31, 2017, in each case, as included in the Company’s 2018 Q2 10Q.

In connection with the Disposition, the Company entered into a Transition Services Agreement pursuant to which Navigant will provide the Buyer with certain services to enable the operation of the Business (“TSA Services”). The TSA Services will include information technology, finance and accounting, human resources and other corporate support services. The TSA Services will be provided at a cost to the Buyer for a period of up to 9 months after the closing of the Disposition for most services, although some services may extend beyond that date. As a result Navigant will continue to incur a higher level of general and administrative costs, which are expected to be partially offset by transitions fees to be received from the Buyer.

The following unaudited pro forma condensed consolidated statements of income for the six months ended June 30, 2018 and for the years ended December 31, 2017, 2016, and 2015 have been prepared giving effect to the Disposition as if the Disposition had occurred on January 1, 2015. The following unaudited pro forma consolidated balance sheets have been prepared giving effect to the Disposition as if the Disposition occurred on June 30, 2018.

The Disposition transaction was valued at $470 million and Navigant expects to realize approximately $370 million in net cash proceeds from the Disposition, after taxes and transaction and separation-related costs. The Company currently plans to use such proceeds to repay third-party indebtedness, return capital to shareholders, fund a dividend announced August 27, 2018, and pursue growth opportunities.

The unaudited pro forma condensed consolidated financial statements are prepared in accordance with Article 11 of RegulationS-X. The pro forma adjustments are described in the accompanying notes and are based upon and derived from information and assumptions available at the time of the filing of the Navigant ClosingForm 8-K.

The unaudited pro forma financial information is based on financial statements prepared in accordance with U.S. generally accepted accounting principles, which are subject to change and interpretation. The unaudited pro forma condensed consolidated financial statements were based on and derived from our historical consolidated financial statements, adjusted for those amounts which were determined to be directly attributable to the Disposition, factually supportable, and with respect to the unaudited pro forma condensed consolidated statements of income, expected to have a continuing impact on our consolidated results. Actual adjustments, however, may differ materially from the information presented. Pro forma adjustments do not include allocations of corporate costs, as those are not directly attributable to the Disposition. In addition, the unaudited pro forma financial information is based upon available information and assumptions that management considers to be reasonable, and such assumptions have been made solely for purposes of developing such unaudited pro forma financial information for illustrative purposes in compliance with the disclosure requirements of the SEC. The unaudited pro forma financial information is not necessarily indicative of what the financial position or income statement results would have actually been had the Disposition occurred on the dates indicated. In addition, these unaudited pro forma condensed consolidated financial statements should not be considered to be indicative of our future consolidated financial performance and income statement results.
