Earnings per Share

    VERNON HILLS, Ill.--(BUSINESS WIRE)--Oct. 18, 2005--Third quarter
of 2005 highlights:

    --  Average daily sales: $26.097 million, an increase of 10.5%
        year-over-year

    --  Sales: $1.670 billion, an increase of 10.5% year-over-year

    --  Net income: $73.1 million, an increase of 12.2% year-over-year

    --  Diluted earnings per share: $0.88, an increase of 15.8%
        year-over-year

    CDW Corporation (NASDAQ:CDWC) achieved record quarterly results
for sales, net income and earnings per share in the third quarter of
2005.
    Third quarter sales totaled $1.670 billion, an increase of 10.5
percent compared to the third quarter of 2004. Third quarter net
income was $73.1 million, an increase of 12.2 percent versus the third
quarter of 2004. Diluted earnings per share were $0.88 in the third
quarter of 2005, an increase of 15.8 percent compared to earnings per
share of $0.76 in the third quarter of 2004.
    "We are pleased to deliver another quarter of record results.
CDW's unique business model focuses on delivering a superior customer
experience, which has enabled us to outpace market growth and
profitably acquire share," said John A. Edwardson, chairman and chief
executive officer. "We achieved growth in every customer channel,
which demonstrates our ability to understand and respond quickly to
our customers' evolving IT demands. Our track record of strong
performance is based on our coworkers' ability to execute well in all
areas of the company on a consistent basis."
    Average daily sales for the third quarter of 2005 were $26.097
million compared to $23.610 million in the third quarter of 2004,
representing a 10.5 percent increase. The third quarter of 2005 and
the third quarter of 2004 both had 64 billing days.
    As previously announced, CDW has created a dedicated healthcare
team, which represents the company's next step in customer
segmentation based on an industry vertical. The healthcare team
addresses the unique IT solution requirements of a range of customers
within the growing healthcare field. Effective July 1, 2005,
approximately 10,000 active healthcare accounts representing
approximately $350 million in annualized revenue were consolidated
from both the corporate and public sectors into a new customer channel
within the public sector. Following this transfer of accounts, the
corporate sector remains primarily comprised of business customers,
and the public sector is comprised of federal and state and local
government entities, educational institutions, and healthcare
customers. Results of operations for 2004 and the first six months of
2005 have been restated for the corporate sector and public sector
solely to reflect this transfer of accounts from one sector of the
company's business to the other. The attached addendum to the
financial information provides these restatements. Consolidated
results are not affected by these restatements.

    --  Third quarter of 2005 average daily sales for the corporate
        sector were $17.448 million compared to $15.899 million,
        representing a 9.7 percent increase over last year. Total
        corporate sector sales in the third quarter of 2005 were
        $1.117 billion compared to $1.018 billion in the third quarter
        of 2004.

    --  Third quarter of 2005 average daily sales for the public
        sector were $8.649 million compared to $7.712 million,
        representing a 12.2 percent increase over last year. Total
        public sector sales in the third quarter of 2005 were $553.6
        million compared to $493.5 million in the third quarter of
        2004.

    --  In the third quarter of 2005 double-digit unit volume growth
        was achieved in notebook CPUs, desktop CPUs, software, data
        storage, printers, video, and memory.

    --  Direct Web sales were $455 million in the third quarter of
        2005, representing a 12.3 percent increase compared to the
        same period a year ago, and comprised 27.3 percent of total
        sales.

    --  September 2005 average daily sales were $28.228 million,
        compared to $25.083 million in September 2004, representing a
        12.5 percent increase. Total September 2005 sales were $592.8
        million compared to $526.7 million in the prior period.
        September 2005 and September 2004 both had 21 billing days.
        Both the corporate and public sector segments generated growth
        in September 2005.

    Gross profit margin was 15.3 percent in the third quarter of 2005
compared to 15.1 percent in the same period of 2004. The increase was
primarily due to an increase in product margin. In addition, a larger
amount of cooperative advertising funds was classified as a reduction
of cost of sales, as an increase in these funds was received to
support an increase in marketing spending. The positive impact from
these items was partially offset by reduced customer charges for
delivery, insurance and handling as a result of modifications in these
charges made in the first quarter of 2005, and a lower level of vendor
incentives due to changes in vendor programs.
    Selling and administrative expenses as a percentage of sales were
6.8 percent in the third quarter of 2005 compared to 6.5 percent in
the third quarter of 2004. The increase was primarily due to increased
expense for the additional profit-sharing contribution to the 401(k)
plan of $1,000 per coworker announced earlier this year in conjunction
with a modification to the company's stock option program; costs of
approximately $1 million related to the opening of the company's new
distribution center in North Las Vegas, Nevada; and increased payroll
costs for a larger number of coworkers to support a larger and growing
business.
    The effective tax rate for the third quarter of 2005 was 36.9
percent, compared to 39.6 percent for the third quarter of 2004. The
tax rate of 36.9 percent for the third quarter of 2005 reflects an
adjustment to the overall effective tax rate to arrive at a combined
rate of 37.4 percent for the first nine months of 2005, which is the
rate the company currently expects for full-year 2005.

    --  As previously announced, the company began collecting sales
        taxes from all taxable commercial customers effective April 1,
        2005. As a result, CDW has begun filing state income tax
        returns in all states. Due to differences in state income tax
        laws, including differences in how income is apportioned, the
        company's overall effective state income tax rate will be
        lower in 2005 compared to 2004.

    --  The revised effective tax rate estimate for 2005 of 37.4
        percent is down slightly from the previous estimate of 37.8
        percent. The decrease is primarily attributable to an increase
        in the estimate of tax-exempt interest income from state and
        municipal securities that will be earned in 2005.

    --  CDW is required to review its effective tax rate estimate on a
        quarterly basis under accounting rules.

    During the third quarter of 2005, CDW repurchased 124,000 shares
of common stock at an average price of $57.42 per share for an
aggregate purchase price of approximately $7 million. Under the
current share repurchase program approved in April 2005 for the
repurchase of 4.5 million shares, 2.9 million shares remain available
for purchase. Total share repurchases for the first nine months of
2005 were approximately 3.9 million at an average price of $56.76 per
share for an aggregate purchase price of approximately $219 million.
Including an annual cash dividend of approximately $35 million, total
dollars returned to shareholders in the first nine months of 2005 were
approximately $254 million.
    The company plans to release October sales on Tuesday, November 8,
2005. October 2004 had 21 billing days and October 2005 will have 21
billing days.
