CHICAGO, July 29, 2010 — Navigant Consulting, Inc. (NYSE:NCI), a global consulting firm providing dispute, investigative, operational, risk management and financial and regulatory advisory solutions, today announced financial results for the second quarter ended June 30, 2010.

“Over the course of the second quarter we made significant progress toward advancing our strategic agenda, as evidenced by the acquisition of Daylight Forensic & Advisory and the addition of senior practitioner talent in several of our key growth areas,” stated William M. Goodyear, Chairman and Chief Executive Officer. “Despite the continuing challenging business environment, our second quarter financial results improved over both first quarter and last year. Additionally, strong cash flow aided by outstanding working capital management enabled us to maintain comfortable debt levels during the quarter while at the same time adding significant new capabilities to the Company.”

Second Quarter 2010 Results

The Company’s second quarter 2010 results are summarized as follows:

Total Company Second Quarter Financial Results (1)

		Q2 2010				Q2 2009				Change				Q1 2010				Change
Revenue Before Reimbursements ($000)		$	154,617			$	157,332				-1.7	%		$	153,870				0.5	%

Average Billable FTEs			1,660				1,832				-9.4	%			1,679				-1.1	%

Navigant’s second quarter 2010 RBR was $155 million, up slightly from $154 million in first quarter 2010 and down slightly from $157 million in second quarter 2009. The Company’s energy, healthcare and economics practices each achieved notable year over year growth, which was partially offset by the impact of previously discussed wind downs and practitioner departures. Continued softness in the disputes environment in the second quarter also adversely impacted year over year comparisons. Companywide utilization for second quarter 2010 was 73%, down from 77% in first quarter 2010 while consistent with second quarter 2009 utilization of 73%. Average bill rate was $266 for second quarter 2010 compared to $264 for first quarter 2010 and $250 for second quarter 2009. Second quarter 2010 bill rate improvements were driven by rate increases in certain markets as well as the engagement and consulting mix for the period. Period end companywide headcount was up slightly from first quarter 2010 and is expected to continue to increase modestly over the remaining two quarters of the year.

Navigant continued its ongoing focus on cost management as reflected by the Company’s second quarter results. Cost of services (before reimbursements) was $102 million for second quarter 2010, on par with second quarter 2009. General and administrative expenses were $29 million for second quarter 2010, down 13% from $34 million for the same period in 2009. Continuing improvements in operating leverage were driven by lower facility, operations, compensation and bad debt costs. Days sales outstanding also improved year over year to 79 at June 30, 2010 from 91 at June 30, 2009.

		Q2 2010				Q2 2009				Change				Q1 2010				Change

Navigant’s Dispute and Investigative Services segment reported RBR of $60 million for second quarter 2010, down 6% from first quarter 2010 and down 15% from second quarter 2009. Attrition and headcount reductions impacted the segment during the first half of 2010 and, as a result, second quarter 2010 average billable FTEs declined 16% from the year ago period. Despite continued solid credit crisis related work, large scale investigations, construction disputes and general litigation continue to be slower than anticipated. The Company’s recent acquisition of Daylight Forensic & Advisory, completed on May 14, 2010, has been integrated into the firm and is exceeding original expectations.

Navigant’s Business Consulting Services segment delivered a strong performance in second quarter 2010 with RBR of $63 million, up 11% from first quarter 2010 and up 10% from second quarter 2009. Utilization was 81% for second quarter 2010 compared to 75% for the year ago period, while average bill rate was $217 for second quarter 2010 compared to $210 for second quarter 2009. The segment’s healthcare and energy teams represented 72% of second quarter 2010 Business Consulting Services revenues, compared to 68% for second quarter 2009. Navigant’s healthcare team experienced broad based demand for its services, fueled by concerns related to the impact of healthcare reform and providers seeking to improve cost structures. Navigant’s energy expertise is also being sought as renewables, energy efficiency and Smart Grid related projects continue to increase in importance to the marketplace. Additionally, the Company’s restructuring and valuations teams performed very well during the period.

Navigant’s International Consulting segment reported RBR of $14 million for second quarter 2010, down 10% from both first quarter 2010 and second quarter 2009. While second quarter 2010 average bill rate improved to $259 from $239 one year ago, average billable FTEs declined to 200 in second quarter 2010 from 233 in second quarter 2009. Declines in segment results for second quarter 2010 generally resulted from the impacts of a weakened European economy combined with the wind down of certain large infrastructure engagements in the construction practice.

Navigant’s Economic Consulting segment achieved RBR of $17 million for second quarter 2010, matching its record first quarter 2010 and up 28% from second quarter 2009. Average bill rate was $385 for second quarter 2010, an increase of 12% from the same period in 2009. Reflecting both the acquisition of Washington, D.C. based Empiris on January 20, 2010 and recent senior level recruiting efforts within the segment, average billable FTEs grew to 119 in second quarter 2010 from 100 in second quarter 2009 and are expected to grow further as the year progresses. Recent senior hires have enabled the segment to expand their expertise in areas such as intellectual property disputes, pharmaceuticals, telecommunications and technology. Ongoing strength in structured finance related litigation matters positively affected second quarter results.

2010 Outlook

Navigant affirmed its 2010 guidance ranges as originally issued on February, 18, 2010. Revenue is estimated to be between $700 and $750 million, and adjusted earnings per share (excluding the net income impact from office consolidation and severance expenses) is estimated to range between $0.75 and $0.85.

“Our outlook continues to assume a stronger second half of the year that reflects Navigant’s existing momentum in its key practice areas, traction from first half senior hire investments and building contributions from our recent acquisitions,” commented Mr. Goodyear. “Although we are not immune to choppy economic conditions, we feel confident that continued improvements are attainable for the firm over the balance of 2010 and into 2011.”

Second Quarter 2010 Earnings Conference Call

Mr. Goodyear will host a conference call to discuss the Company’s second quarter 2010 financial results and full year 2010 outlook at 10:00 a.m. Eastern Time on Thursday, July 29, 2010.

RECONCILIATION OF NON GAAP FINANCIAL MEASURES
(In thousands, except per share data)
(Unaudited)

Non-GAAP Financial Information

This press release includes certain non-GAAP financial information as defined by Securities and Exchange Commission Regulation G. Pursuant to the requirements of this regulation, reconciliations of this non-GAAP financial information to the Company’s financial statements as prepared under generally accepted accounting principles (GAAP) are included in this press release. During 2009, the Company incurred significant severance expense as staffing levels were adjusted to market demand and Navigant executed its strategic refresh initiative involving the redeployment of certain resources. The Company also continues to be impacted by office consolidation expense due to its real estate initiatives including the impact of closing certain offices and changes in market conditions associated with expected sublease proceeds. Adjusted EBITDA and adjusted operating income excludes the impact of severance and office consolidation expense and adjusted earnings per share excludes the net income impact of severance and office consolidation expense in all periods presented. Severance and office consolidation expense are not considered to be non-recurring, infrequent or unusual to our business, however, management believes providing investors with this information gives additional insights into Navigant’s operating performance. While management believes that these non-GAAP financial measures are useful in evaluating Navigant’s operations, this information should be considered as supplemental in nature and not as a substitute for or superior to, any measure prepared in accordance with GAAP.

EBITDA, Adjusted EBITDA, Adjusted operating income

EBITDA (earnings before interest, taxes, depreciation and amortization) is not a measure of financial performance under generally accepted accounting principles (GAAP). The Company believes EBITDA provides useful supplemental information for investors to evaluate financial performance. This data is also used by the Company for assessment of its operating and financial results, in addition to operating income, net income and other GAAP measures. Management believes EBITDA is a useful indicator of the Company’s financial and operating performance and its ability to generate cash flows from operations that are available for interest, debt service, taxes and capital expenditures. Investors should recognize that EBITDA might not be comparable to similarly-titled measures of other companies. Adjusted EBITDA and adjusted operating income excludes the impact of severance and office consolidation expense as discussed above. This measure 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.
