SEGMENT OVERVIEW

In North America, net sales were $915.2 million for the fourth quarter of 2010, up 17% from the fourth quarter of 2009. Net sales of hardware and software increased 21% and 16%, respectively, year over year, while net sales in the services category declined 10% year to year. Gross profit was up 9% year over year at $113.0 million, with gross margin declining 100 basis points to 12.3% for the fourth quarter of 2010 from 13.3% in the prior year quarter. Gross profit and margin during the fourth quarter of 2010 benefited from the elimination of approximately $3.8 million of certain trade credit liabilities through negotiated settlement or other legal release of the recorded liabilities. Comparatively, gross profit and margin in the fourth quarter of 2009 benefited from approximately $1.6 million related to the elimination of trade credits. Selling and administrative expenses in North America were $88.6 million during the fourth quarter of 2010, compared to $85.9 million in the fourth quarter of 2009. Selling and administrative expenses in the prior year fourth quarter included a $2.9 million bad debt charge associated with a single significant doubtful account identified during the fourth quarter of 2009 as well as approximately $1.1 million of restatement related professional fees and costs. The North America segment recorded $861,000 of severance and restructuring expenses during the fourth quarter of 2010. During the fourth quarter of last year, North America recorded no severance expense. As a result, earnings from operations in North America were $23.5 million, or 2.6% of net sales, in the fourth quarter of 2010, an increase of 32% from $17.8 million, or 2.3% of net sales, in the fourth quarter of 2009.

Insight Q4 2010 Results, Page 3		February 14, 2011

Throughout this “Segment Overview” section, the Company refers to changes in net sales, gross profit and selling and administrative expenses in EMEA and APAC excluding the effects of foreign currency movements. In computing these changes and percentages, the Company compares the current year amount as translated into U.S. dollars under the applicable accounting standards to the prior year amount in local currency translated into U.S. dollars utilizing the average translation rate for the current year.

GUIDANCE

As the Company has previously disclosed, the Company’s largest software partner has informed resellers that it intends to change certain elements of its channel incentive programs effective in late 2011. Additional details of the new programs have recently been announced and as a result, the Company has updated its analysis and now expects the full year 2012 impact on gross profit to be between $5 and $10 million. The program changes will be finalized over the coming months and in the meantime, the Company is implementing action plans intended to help mitigate this expected impact.

For the full year of 2011, the Company expects the global IT market to grow in the mid single digit range. The Company expects to exceed the market growth rate but expects higher year to year growth rates in sales in the first half of the year and lower rates in the back half given the growth the Company experienced throughout 2010. This dynamic is largely driven by the hardware category as the Company expects typical seasonality in 2011 in the software category. The Company currently expects gross margin for the full year to approximate the gross margin the Company experienced in 2010. The Company intends to continue to invest in its sales force and its IT systems integration projects in North America and EMEA throughout the year. As a result, the Company expects diluted earnings per share for the full year of 2011 to be between $1.70 and $1.80.

This outlook does not include any potential severance and restructuring expenses.
