Exhibit 99.1

NAVIGANT REPORTS SECOND QUARTER 2014 FINANCIAL RESULTS

CHICAGO, July 29, 2014 – Navigant (NYSE:NCI) today announced financial results for the second quarter ended June 30, 2014. Results for the quarter include the partial period contribution from Cymetrix Corporation, a revenue cycle management firm providing services to hospital and healthcare networks, acquired on May 14, 2014.

Financial Summary and Highlights:

Navigant reported second quarter 2014 RBR of $186.5 million compared to $187.1 million for second quarter 2013. Total revenues for the Company were $208.1 million for second quarter 2014 compared to $209.7 million for second quarter 2013. The Company reported a net loss from continuing operations for second quarter 2014 of $75.9 million, or $1.55 per share, reflecting a non-cash goodwill impairment of $122.0 million ($86.9 million or $1.78 per share on an after-tax basis) to reduce the carrying value of goodwill related to the Disputes, Investigations & Economics segment. Net income from continuing operations in the prior year quarter was $14.2 million, or $0.28 per share. Adjusted EPS was $0.22 for second quarter 2014 compared to $0.31 for second quarter 2013. Adjusted EBITDA was $27.4 million for second quarter 2014 compared to $34.5 million for the second quarter 2013.

Julie Howard, Chairman and Chief Executive Officer, commented, “During the quarter, better-than-expected performance from several regulatory compliance matters in the Financial, Risk & Compliance segment only partially offset lower organic growth in other areas, particularly in our Healthcare segment. However we still expect to deliver on our previously stated RBR expectations for the full year 2014, albeit with a different mix among business areas than previously anticipated. Longer term, we expect our Healthcare and Energy segments to reaccelerate organic growth as we benefit from favorable industry demand trends in these high-growth sectors and as we continue to pursue and develop solutions that offer more consistent, recurring revenue opportunities. During the quarter, we announced the acquisition of Cymetrix which represents an important step in this direction. This and other recent investments, along with the addition of senior hires throughout the organization, are expected to accelerate our growth plans but have impacted near-term profitability.”

Segment Financial Summary

Healthcare RBR increased 16% year-over-year for second quarter 2014. Growth was driven by an increased contribution from Navigant’s revenue cycle management services, which include both the Cymetrix and Alleviant operations. The integration of the acquired Cymetrix operations is proceeding according to plan. On an organic basis, RBR was flat for the segment in the second quarter, year over year, primarily because two sizeable engagements that were completed in the second half of 2013 have not yet been replaced with similarly sized projects in 2014. Additionally, the U.S. Government’s postponement of the ICD-10 compliance date has caused some clients to cancel or delay their related engagements. Segment operating profit was 15% lower compared to second quarter 2013. Navigant expects a resumption of year-over-year organic growth in the Healthcare segment in the second half of 2014.

The Financial, Risk & Compliance segment benefited from strong demand from financial institutions which are required to address heightened regulation and compliance requirements. The segment delivered better-than-anticipated RBR for second quarter 2014, resulting in a smaller than expected year-over-year RBR decline compared to second quarter 2013. The decline in year-over-year RBR reflects significant RBR from mortgage servicing review engagements in the second quarter of 2013 which were substantially completed in the first half of 2013 as well as the expected reduced RBR contribution from restructuring services in 2014. For the second quarter 2014, segment operating margin remained stable at 42% as segment operating profit declined 19% year-over-year, consistent with the expected decline in RBR.

RBR performance for the Energy segment in the second quarter 2014 was relatively consistent compared to second quarter 2013 RBR. Segment operating profit in the second quarter 2014 decreased 13% year over year due to investments in senior hires during 2014. Navigant expects to benefit over time from the recent investments in senior hires and ongoing alignment of resources with anticipated market trends. Additionally, Navigant is investing in the expansion of the segment’s capabilities more broadly into other growth areas, including oil and gas.

Stable RBR performance in the Disputes, Investigations & Economics segment for second quarter 2014 compared to 2013 reflected strong demand in the global construction sector and in the legal technology solutions area. These improvements were offset by lower RBR from the economics business and from international arbitration services which experienced a very strong environment in the prior year period. Segment operating profit increased 3% compared to the same period of 2013.

Goodwill Impairment

After performing its annual goodwill impairment test during the second quarter of 2014 and in connection with the preparation of its second quarter 2014 financial statements, the Company determined that a pre-tax goodwill impairment of $122.0 million related to its Disputes, Investigations & Economics segment was necessary. In making this determination, the Company considered historical financial performance, future projections for the segment and other considerations. The impairment is only partially deductible for income tax purposes, reducing the associated tax benefit of the impairment and resulting in the Company’s second quarter 2014 effective tax rate being significantly lower than historical rates. The goodwill impairment was non-cash in nature and did not affect the Company’s current liquidity, cash flows, borrowing capability or operations, nor did it impact the debt covenants under its credit agreement.

Cash Flow

Net cash provided by operating activities was $35.2 million for second quarter 2014 compared to $47.5 million for the same period in 2013. Free cash flow was $17.2 million for second quarter 2014 compared to $24.5 million for the same period in 2013. The decrease in free cash flow was primarily due to lower earnings in second quarter 2014 compared to 2013 and increased capital spending, primarily on technology infrastructure and software investments. DSO was 82 days as of June 30, 2014 compared to 79 days at June 30, 2013.

Bank debt was $188.8 million at June 30, 2014 compared to $128.1 million at June 30, 2013. The increase reflects additional borrowings to fund the Cymetrix acquisition. Leverage (bank debt divided by trailing twelve month adjusted EBITDA) increased to 1.71 at June 30, 2014 compared to 1.05 at June 30, 2013.

Navigant repurchased 404,508 shares of common stock during second quarter 2014 at an aggregate cost of $7.0 million and an average cost of $17.39 per share. As of June 30, 2014, $85.6 million remained on the Company’s share repurchase authorization.

Lucinda (Cindy) Baier, Executive Vice President and Chief Financial Officer, commented, “We are excited to add Cymetrix to our portfolio during the second quarter, and we are pleased with the initial progress of the integration. The financial flexibility resulting from our significant deleveraging over the past several years enabled us to use our credit facility to finance the acquisition of Cymetrix. Moving forward, we plan to make the necessary investments in additional infrastructure and technology to ensure a successful integration of the acquired operations while maintaining the ability to pursue additional growth initiatives. At the same time, our anticipated strong operating cash flows are expected to help reduce our leverage ratio to under 1.5 by the end of 2014 even as we continue to return cash to shareholders through our ongoing share repurchase program.”

2014 Outlook

Navigant reiterated its full year 2014 outlook of RBR in the range of $772 and $816 million with 2014 total revenues estimated in the range of $848 and $892 million. Adjusted EBITDA is expected to range between $120 and $130 million and adjusted EPS is estimated to be between $0.94 and $1.06.
