Additionally, we have high expectations as we enter 2015 about our prospects to build on the strong foundation and combination of specialized consulting, technology solutions and business process management services we now have in place.”

Howard continued, “We expect the anticipated market trends, industry reforms and regulatory environments facing our clients will lead to increasing demand for our complementary mix of expertise and solutions that address business risk, business performance and business transformation.”

Segment Financial Summary

2

RBR for the Healthcare segment increased 39% year-over-year for fourth quarter 2014 with 1% organic RBR growth for the period. RBR growth was driven primarily by business process management services, which includes the Cymetrix operations acquired in May 2014. Segment operating profit margin was 27% versus 36% in the same period last year, mainly due to the lower margin profile of the business process management services operations. For full year 2014, RBR increased 22% year-over-year, also primarily driven by the business process management services operations. Segment operating profit margin was 29% in 2014 compared to 37% in 2013, as a result of the lower margin profile of the business process management services operations in addition to costs of maintaining consulting capabilities despite lower than anticipated levels of RBR.

The Financial, Risk & Compliance segment RBR for fourth quarter 2014 decreased 8% compared to the prior year quarter. Growth driven by continued demand from large financial institutions was offset by a previously anticipated reduction in RBR from restructuring-related services. Growth of more profitable engagements led to a 1% increase in fourth quarter 2014 segment operating profit year-over-year. For full year 2014, an RBR decrease of 13% and a segment operating profit decrease of 6%, respectively, were substantially less than anticipated as compared to 2013. Segment performance for the year reflects the expected reduced contribution from mortgage servicing review engagements and restructuring-related services, partially offset by new compliance work from large financial institutions.

The Energy segment RBR for fourth quarter 2014 increased 12%, which was entirely organic, compared to fourth quarter 2013. The segment benefitted from investments made in senior hires earlier in the year in addition to the continued demand for energy efficiency and demand-side energy management services. Fourth quarter 2014 segment operating profit increased 11% year-over-year. Full year 2014 RBR increased 3%, which was entirely organic, versus the prior year. Segment operating profit for full year 2014 declined 2% compared to 2013, mainly due to investments in senior hires during the first half of 2014.

The Disputes, Investigations & Economics segment fourth quarter 2014 RBR increased 6% year-over-year, which was nearly all organic. The increase was driven primarily by higher demand for our legal technology solutions and general litigation, and increased activity in global construction, which included a success fee of $1.9 million, partially offset by a lower contribution from economics engagements. Segment operating profit increased 15% in fourth quarter 2014 compared to the same period of 2013. Full year 2014 RBR increased 3% compared to 2013. Segment operating profit for 2014 increased 5% compared to 2013.

Cash Flow

Free cash flow was $12.7 million for fourth quarter 2014 compared to $15.2 million for the same period in 2013. Full year 2014 free cash flow was $72.4 million compared to $78.8 million for 2013. Days Sales Outstanding (DSO) was 69 days as of December 31, 2014, up 4 days compared to December 31, 2013, reflecting the very strong cash collections in fourth quarter 2013.

3

Bank debt was $109.8 million at December 31, 2014 compared to $56.7 million at December 31, 2013. Leverage (bank debt divided by trailing twelve month adjusted EBITDA) was 0.94 at December 31, 2014 compared to 0.46 at December 31, 2013. However, 2014 fourth quarter debt levels declined sequentially from the 2014 second and third quarters following additional borrowings to fund the Cymetrix acquisition in second quarter 2014.

Navigant repurchased 449,191 shares of common stock during fourth quarter 2014 at an aggregate cost of $6.5 million and an average cost of $14.44 per share. For the full year, the Company repurchased approximately 1.7 million shares at an aggregate cost of $27.3 million and an average cost of $16.50 per share. As of December 31, 2014, $72.7 million was available under the Company’s share repurchase authorization.

“We made significant progress in advancing our growth strategy during 2014,” said Lucinda (Cindy) Baier, Executive Vice President and Chief Financial Officer. “In particular, we completed strategic acquisitions and made organic investments to both complement and enhance our core businesses. As always, we remained intensely focused on strong capital management while investing in our future. Looking ahead, we are focused on generating improved organic revenue growth in 2015 and further positioning the company for success over the long term.”

2015 Outlook

Navigant is introducing its 2015 financial outlook. Full year 2015 RBR is expected to range between $815 and $845 million while 2015 total revenues are estimated to be between $900 and $930 million. Adjusted EBITDA is expected to range between $115 and $125 million and adjusted EPS is estimated to be between $0.90 and $1.00.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES (3)

(In thousands, except per share data)

(Unaudited)

This press release includes certain non-GAAP financial measures as defined by the Securities and Exchange Commission. Below are the reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated and presented in accordance with generally accepted accounting principles (GAAP). This information should be considered as supplemental in nature and not as a substitute for, or superior to, any measure of performance prepared in accordance with GAAP. Management uses these non-GAAP financial measures in addition to GAAP financial measures to assess the Company's operations and financial results and believes they are useful indicators of operating performance and the Company's ability to generate cash flows from operations that are available for interest, debt service, taxes and capital expenditures. Investors should recognize that these non-GAAP financial measures may not be comparable to similarly-titled measures of other companies.

    Footnotes

(1) Per share data may not sum due to rounding.

(2) For the year ended December 31, 2014, the Company reported a net loss. For that period, the basic weighted average common shares outstanding equals the diluted weighted average common shares outstanding for purposes of calculating U.S. GAAP earnings per share because potentially dilutive securities would be antidilutive.

(3) During the year ended December 31, 2013, the United Kingdom financial services advisory business was sold. The results of operations from this business are presented as discontinued operations. All non-GAAP financial measures are presented on a continuing operations basis unless otherwise noted.

(4) EBITDA is earnings from continuing operations before interest, taxes, depreciation and amortization. Adjusted EBITDA excludes the impact of severance expense and other operating costs (benefit). Adjusted net income and adjusted earnings per share exclude the net income (loss) and per share net income (loss) impact of discontinued operations, severance expense and other operating costs (benefit). Severance expense and other operating costs (benefit) are not considered to be non-recurring, infrequent or unusual to our business. Management believes that these measures provide investors with enhanced comparability of the Company's results of operations across periods.

(5) Effective income tax expense (benefit) has been determined based on specific tax jurisdiction.

(6) For the year ended December 31, 2014, the Company reported a net loss. For non-GAAP purposes, the per share and share amounts presented here reflect the inclusion of potentially dilutive shares based on the impact of the add backs included in Adjusted Net Income.

(7) Free cash flow is calculated as net cash provided from operations excluding changes in assets and liabilities and allowance for doubtful accounts receivable less cash payments for property and equipment and deferred acquisition related payments. Free cash flow does not represent discretionary cash available for spending as it excludes certain contractual obligations such as debt repayment. However, management believes that it provides investors with an indicator of cash flows available for on-going business operations and long term value creation.

(8) Leverage ratio is calculated as bank debt at the end of the period divided by adjusted EBITDA for the prior twelve-month period. Management believes that leverage ratio provides investors with an indicator of the cash flows available to repay the Company's debt obligations.
