NAVIGANT REPORTS THIRD QUARTER 2014 FINANCIAL RESULTS

CHICAGO, October 28, 2014 – Navigant (NYSE:NCI) today announced financial results for the third quarter ended September 30, 2014.

Financial Summary and Highlights:

Navigant reported third quarter 2014 RBR of $205.5 million, a 10% increase compared to $186.4 million for third quarter 2013, with year-over-year RBR growth in three segments. Total revenues for the Company were $230.1 million for third quarter 2014 compared to $211.6 million for third quarter 2013. Net income from continuing operations for third quarter 2014 increased 20% to $16.3 million, or $0.33 per share, compared to $13.5 million, or $0.27 per share in the prior year quarter. Contributing to profit margin improvement, third quarter 2014 general and administrative expenses were flat compared to prior year. The effective income tax rate was 42% for third quarter 2014 compared to 47% in the prior year quarter. Adjusted EPS was $0.32 for third quarter 2014 compared to $0.25 for third quarter 2013, an increase of 28%. Adjusted EBITDA was $36.3 million for third quarter 2014 compared to $30.8 million for third quarter 2013, an increase of 18%.

Julie Howard, Chairman and Chief Executive Officer, commented, “Despite mixed results in our Healthcare practice, we demonstrated progress against our organic growth objectives in the period with gains in our Disputes, Investigations & Economics and Energy segments. Additionally, the Financial, Risk & Compliance segment outperformed our expectations as regulatory compliance actions drove new assignments.”

Howard continued, “The Healthcare segment posted substantial revenue gains in the third quarter driven primarily by our enhanced revenue cycle management services which include the acquired Cymetrix operations. At the same time, we are experiencing softness and competitive challenges in our performance improvement practice within the Healthcare segment which has impacted organic growth at both the segment and company level. We believe we are taking the necessary actions to reaccelerate growth in this area, and we remain confident in our overall strategic direction. However, we have updated our outlook to reflect our recent performance and anticipated trends for the balance of the year.”

Segment Financial Summary

RBR for the Healthcare segment increased 31% year-over-year for third quarter 2014 with a 2% decline in organic RBR growth for the period. Segment RBR growth in third quarter 2014 was driven primarily by revenue cycle management services, specifically the strong performance from the recently acquired Cymetrix operations and an increased contribution from our Alleviant business. Partially offsetting these gains was weaker demand for large implementation engagements within the Healthcare segment’s performance improvement area and lack of recovery in ICD-10 preparation services. Segment operating profit increased 4% compared to third quarter 2013 reflecting the contribution of the Cymetrix and Alleviant operations, albeit at a lower margin, partially offset by the effect of maintaining capabilities for a higher level of RBR in other areas of the segment.

The Financial, Risk & Compliance segment continued to respond to strong demand from large financial institutions for expertise to remediate and operationalize improvements related to their compliance and control environments. While we anticipated a year-over-year decline in third quarter 2014 RBR for this segment, the rate of decline was better-than-expected at 7% for the period. For third quarter 2014, segment operating profit increased 2% year-over-year, reflecting an improved mix of more profitable engagements.

The Energy segment achieved 12% organic and overall RBR growth in third quarter 2014 compared to third quarter 2013 reflecting broad improvement across the segment, including contributions from recent organic investments in senior hires and key market expansion. Third quarter 2014 results also benefited from long-term engagements beginning after an extended contracting process. Segment operating profit in third quarter 2014 increased 26% year-over-year due to increased RBR and improved alignment of resources.

The Disputes, Investigations & Economics segment contributed 4% organic RBR growth and 6% overall RBR growth for third quarter 2014 compared to third quarter 2013. Increased demand for general litigation assistance and improved positioning of resources to capitalize on demand within the global construction sector drove higher RBR in 2014. Legal technology solutions also contributed to the year-over-year RBR growth. Segment operating profit increased 6% compared to the same period of 2013, consistent with the increase in RBR.

Cash Flow

Net cash provided by operating activities was $39.4 million for third quarter 2014 compared to $35.1 million for the same period in 2013. Free cash flow was $24.0 million for third quarter 2014 compared to $17.3 million for the same period in 2013. The increase in free cash flow was primarily due to improved earnings in third quarter 2014 compared to 2013 partly offset by increased capital spending, primarily on technology investments. Days Sales Outstanding (DSO) improved to 77 days as of September 30, 2014 compared to 81 days at September 30, 2013.

The Company used $30.1 million of cash to pay down bank debt during third quarter 2014. Bank debt was $158.0 million at September 30, 2014 compared to $110.0 million at September 30, 2013. The year-over-year increase primarily reflects additional borrowings to fund the Cymetrix acquisition in the second quarter of 2014, net of debt repayments to banks. Leverage (bank debt divided by trailing twelve month adjusted EBITDA) was 1.36 at September 30, 2014 compared to 0.86 at September 30, 2013.

Navigant repurchased 390,624 shares of common stock during third quarter 2014 at an aggregate cost of $6.4 million and an average cost of $16.31 per share. As of September 30, 2014, $79.2 million remained on the Company’s share repurchase authorization.

Lucinda (Cindy) Baier, Executive Vice President and Chief Financial Officer, commented, “Following the acquisition of Cymetrix in the second quarter, we have reduced indebtedness quarter-over-quarter while continuing to return capital to shareholders through our ongoing share repurchase program. While it is still in the early stages of our investment with Cymetrix, we have completed the initial phase of integration and have been pleased with the contribution from these operations thus far. We expect to maintain our fiscal discipline which should enable us to consider additional opportunities to position Navigant for long-term, profitable growth through both internal investment and acquisition.”

2014 Outlook

Navigant is updating its outlook for 2014 to reflect recent performance as well as expectations for fourth quarter 2014. Full year 2014 RBR is now estimated in the range of $757 and $770 million with 2014 total revenues now estimated in the range of $846 and $859 million. Adjusted EBITDA is now expected to range between $109 and $114 million and adjusted EPS is now estimated to be between $0.92 and $0.97.

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).

Footnotes

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

(2) For the nine months ended September 30, 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 nine months ended September 30, 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.
