    CDW Corporation (NASDAQ: CDWC) a leading provider of technology
products and services to business, government and education, today
announced record quarterly sales, gross profit and operating income in
the first quarter of 2007. The Company previously announced March 2007
and first quarter of 2007 sales results.

    "Our strong results demonstrate the progress we are making to
leverage our 2006 investments, which include the geographic
realignment of medium and large customer accounts in the corporate
sector and the acquisition of Berbee Information Networks," said John
A. Edwardson, chairman and chief executive officer. "Thanks to the
determined efforts of our CDW coworkers, we grew approximately three
times the market rate of growth and achieved solid profitability in
all operating segments. While we are pleased with our record quarter,
we remain focused on executing our growth strategies, leveraging our
expanded infrastructure and finding innovative ways to continue to
profitably take market share. Most importantly, our future success
will be driven by our increasing ability to be a single source
provider of IT products and services and continuing to provide an
unmatched experience for our customers."

    Total sales in the first quarter of 2007 were $1.859 billion
compared to $1.589 billion in the first quarter of 2006, an increase
of 17.0 percent. Average daily sales in the first quarter of 2007 were
$29.049 million compared to $24.822 million in the first quarter of
2006, representing a 17.0 percent increase. There were 64 billing days
in both the first quarter of 2007 and the first quarter of 2006.

    CDW completed the acquisition of Berbee Information Networks on
October 11, 2006. Total sales for the first quarter of 2006 do not
include Berbee sales, while the first quarter of 2007 sales include
Berbee sales. Excluding Berbee sales in the first quarter of 2007, and
therefore on a non-GAAP basis, total sales were $1.716 billion, an
increase of 8.0 percent compared to total sales of $1.589 billion for
the first quarter of 2006 and average daily sales for the first
quarter of 2007 were $26.819 million, an increase of 8.0 percent
compared to average daily sales for the first quarter of 2006 of
$24.822 million.

    First Quarter of 2007 Highlights:

    --  Total corporate sector segment sales in the first quarter of
        2007 were $1.219 billion compared to $1.150 billion in the
        first quarter of 2006, representing an increase of 6.0
        percent. First quarter of 2007 average daily sales for the
        corporate sector segment were $19.047 million compared to
        $17.972 million in the first quarter of 2006, representing an
        increase of 6.0 percent.

    --  Total public sector segment sales in the first quarter of 2007
        were $497.4 million compared to $438.4 million in the first
        quarter of 2006, representing an increase of 13.4 percent.
        First quarter of 2007 average daily sales for the public
        sector segment were $7.772 million compared to $6.851 million
        in the first quarter of 2006, representing an increase of 13.4
        percent.

    --  While CDW did not own Berbee prior to October 11, 2006, the
        Company is providing comparative information for Berbee. Total
        Berbee sales in the first quarter of 2007 were $142.7 million
        compared to $84.3 million in the first quarter of 2006,
        representing an increase of 69.3 percent. First quarter of
        2007 average daily sales for Berbee were $2.229 million
        compared to $1.317 million in the first quarter of 2006,
        representing an increase of 69.3 percent. Compared to the
        corporate sector and public sector segments, Berbee's business
        model is more project oriented, which can result in a greater
        degree of variability in sales on a monthly basis.

    --  Product categories that achieved the strongest year-over-year
        unit volume growth for the first quarter of 2007 were notebook
        computers, data storage, software, video and input devices.
        Product categories exclude Berbee sales.

    --  Direct web sales in the first quarter of 2007 were $550.8
        million, representing a 10.0 percent increase compared to the
        prior year, and comprised 32.1 percent of total sales
        excluding Berbee. Berbee's sales are not made on the web due
        to the higher services component of the sales.

    Gross profit for the first quarter of 2007 was $301.3 million
compared to $253.9 million in the first quarter of 2006, representing
an 18.7 percent increase. Gross profit margin was 16.2 percent of
sales in the first quarter of 2007 compared to 16.0 percent of sales
in the first quarter of 2006. The increase was primarily due to an
increased level of vendor incentives, increased commission revenue and
the inclusion of Berbee, partially offset by a lower amount of
cooperative advertising funds classified as a reduction of cost of
sales and a slightly lower product margin.

    Selling and administrative expenses as a percentage of sales were
8.3 percent in the first quarter of 2007 compared to 8.1 percent in
the first quarter of 2006 and increased $25.4 million. The increase in
selling and administrative expenses in the first quarter of 2007 was
primarily due to the inclusion of Berbee's operating expenses and
increased payroll costs as a result of continued investment in
expanding CDW's sales force.

    Advertising expense was $29.2 million, representing 1.6 percent of
sales in the first quarter of 2007 compared to $30.9 million,
representing 2.0 percent of sales in the first quarter of 2006.
Advertising expense was slightly lower in the first quarter of 2007
versus the prior year primarily due to a lower amount of cooperative
advertising funds reclassified as a reduction of cost of sales.

    Operating margin was 6.3 percent in the first quarter of 2007
compared to 5.9 percent in the first quarter of 2006.

    Net income was $76.8 million in the first quarter of 2007 compared
to $61.7 million in the first quarter of 2006, an increase of 24.5
percent. Diluted earnings per share were $0.96 in the first quarter of
2007 compared to diluted earnings per share of $0.75 in the first
quarter of 2006.

    During the first quarter of 2007, CDW repurchased 254,000 shares
of common stock at an average price of $63.53 per share for an
aggregate purchase price of $16 million. Under the current share
repurchase program approved in April 2006 for the repurchase of 5.0
million shares, 2.9 million shares remain available for purchase.

    The company plans to release April sales on Wednesday, May 9,
2007. April 2006 had 20 billing days and April 2007 will have 21
billing days.
