    CHICAGO--(BUSINESS WIRE)--Feb. 16, 2006--Navigant Consulting, Inc.
(NYSE:NCI):

        of 2004. Annual revenues increased 19 percent, to $575.5
        million, compared to $482.1 million in 2004.

    --  EBITDA for the quarter increased 17 percent to $26.6 million

    --  Net income per diluted share for the fourth quarter 2005 was
        $0.22, consistent with the fourth quarter of 2004. EPS for the
        2005 year increased 19 percent, to $0.95, from $0.80 for 2004.

    Navigant Consulting, Inc. (NYSE:NCI), an independent international
consulting firm providing the industry expertise and solutions clients
need to address dispute, investigative, business, operational and
financial advisory challenges, today announced financial results for
the fourth quarter and full year 2005.

    Fourth Quarter 2005 Financial Results

    Revenues for the fourth quarter of 2005 were $150.5 million, a 16
percent increase compared to the fourth quarter 2004 revenues of
$129.3 million, and consistent with third quarter 2005 revenues.
    EBITDA in the fourth quarter of 2005 was $26.6 million, an
increase of 17 percent from $22.8 million for the fourth quarter of
2004, and down from third quarter 2005 EBITDA of $29.1 million. EBITDA
as a percentage of revenues before reimbursements was 20 percent for
the fourth quarter of 2005.
    Net income per diluted share was $0.22 in the fourth quarter of
2005, consistent with the comparable period in 2004, and down from
$0.25 per share in the third quarter of 2005.
    The Company's profitability during the fourth quarter was impacted
by the resolution of a claim for $1.25 million arising in the fourth
quarter related to the completion of a multi-year engagement in the
Energy practice, and a $1.4 million write off of an uncollectible
receivable from a municipality discussed hereinafter. These amounts
resulted in a pre-tax charge of $2.65 million against 2005 fourth
quarter earnings, $1.5 million after taxes, or $0.03 per share.
    "Exclusive of these charges, the Company completed a solid fourth
quarter and is well-positioned to continue meeting our long term
objective of expanding revenues by 10 to 20 percent annually," stated
William M. Goodyear, Chairman and Chief Executive Officer. "As the
year progressed, our Financial & Insurance Services, Construction and
Government Contractor practices realized accelerated demand and
contributed greatly to the overall success we achieved in 2005."

    Full Year 2005 Financial Results

    Revenues for the year ended December 31, 2005 were $575.5 million,
a 19 percent increase compared to 2004 revenues of $482.1 million.
EBITDA for the full year 2005 was $108.0 million, up 31 percent from
$82.2 million for the comparable 2004 period, and 21 percent of
revenues before reimbursements. EPS for full year 2005 was $0.95 per
share, compared to $0.80 per share for 2004, a 19 percent year over
year increase.
    "Looking back to 2005, we added materially to the depth and
breadth of the firm -- increasing our capabilities, enhancing our
teams with new talent and extending our professional services into new
geographies," said Mr. Goodyear. "Our reach was positively impacted by
the growth of our Corporate Finance practice, the extension of our
Financial & Insurance service capabilities and expertise, our
increased Healthcare strategy capabilities, our strengthened
construction dispute practice, and the expansion of our international
footprint," stated Mr. Goodyear.

    Business Metrics

    Billable consultant headcount, full time equivalents (FTE), as of
December 31, 2005 was 1,705, down slightly from 1,719 at the end of
the third quarter. Company-wide consultant utilization in the fourth
quarter was 67 percent, up from 66 percent during the 2004 fourth
quarter, and down from 71 percent in the third quarter of 2005,
reflecting the impact of the holidays and a traditional slowdown in
overall business activity in the fourth quarter.
    Annualized revenue per consultant in the fourth quarter of 2005
was $358,000, consistent with the third quarter, and up from $351,000
during the fourth quarter of 2004. Annualized attrition was 19 percent
during the fourth quarter of 2005, up from 17 percent in the third
quarter of 2005 and 2004's fourth quarter. Days sales outstanding as
of December 31, 2005 improved significantly to 80 days, compared to 93
days at the end of the 2005 third quarter. The Company ended the year
with $40.8 million in borrowings under its $175 million unsecured,
multi-bank credit facility. This amount is down from $69.7 million at
the end of the third quarter 2005.
    "Throughout 2005, we optimized our investments in both acquisition
and organic hiring," stated Julie M. Howard, Executive Vice President
and Chief Operating Officer. "For 2006, we have organized around two
client facing channels -- Dispute, Investigative and Regulatory
Advisory services, and Business, Financial and Operational Advisory
services. Our new structure better enables us to leverage the diverse
and complementary resources of the organization."

    Company Receives Order from Arbitrator

    Yesterday afternoon, February 15, the Company received an adverse
order and "interim finding" from an arbitrator in a proceeding related
to a previously disclosed dispute with the City of Vernon, California.
RMI-US, a subsidiary of the Company, provided electric distribution
system maintenance services to the City until November 30, 2003, at
which time the contract was terminated at the request of RMI-US. Since
that time, the Company no longer provides such system maintenance
services.
    The arbitrator's order and "interim finding" denied the Company's
right to recover unpaid fees and expenses previously billed to the
City. As such, $1.4 million was charged to expense in the Company's
fourth quarter 2005 income statement. In addition, the arbitrator
found that, as a result of the suspension of the subsidiary's
contractor's license for 19 days in 2001 and 30 days in 2003 during
the 5-year contract period, the City is entitled to a recovery for
unspecified amounts paid under the contract for a period not defined
in the order. The arbitrator also found that the City is entitled to
treble damages but, as previously stated, the order did not indicate
the amount of damages that would be trebled.
    While the order does not state the amount to be reimbursed, the
total amount could have a material adverse impact on the Company's
2005 results of operations and financial position, as preliminarily
reported in this release. The Company strongly disagrees with the
order and the "interim finding" and will promptly seek clarification
and reconsideration of the order and the interim finding.
