FOR IMMEDIATE RELEASE NASDAQ: NSIT

INSIGHT ENTERPRISES, INC. REPORTS FIRST QUARTER 2013 RESULTS

TEMPE, AZ – May 1, 2013 – Insight Enterprises, Inc. (NASDAQ: NSIT) (the “Company”) today reported results of operations for the quarter ended March 31, 2013.

First Quarter Highlights

For the first quarter of 2013 compared to the first quarter of 2012:

• Net sales decreased 5% to $1.2 billion.

• Gross profit declined 7% to $158.1 million, or 13.4% of net sales.

• Earnings from operations were down 44% to $14.4 million, or 1.2% of net sales.

• Net earnings and diluted earnings per share were $9.1 million and $0.20, respectively, in the first quarter of 2013, at an effective tax rate of 27.8%.

• Excluding severance and restructuring expenses, net earnings and diluted earnings per share on a non-GAAP basis were $10.9 million and $0.24, respectively, in the first quarter of 2013.*

• The Company generated $16.3 million of cash from operations in the first quarter of 2013, compared to using $20.4 million during the first quarter of 2012.

• The Company paid down debt by $19.0 million during the first quarter of 2013, ending the quarter with $61.0 million of long-term debt outstanding.

• The Company repurchased approximately 345,000 shares of its common stock for $6.9 million.

* A tabular reconciliation of financial measures prepared in accordance with United States generally accepted accounting principles (“GAAP”) to non-GAAP financial measures is included at the end of this press release.

“In the first quarter, we saw additional weakness in demand for IT products by large enterprise clients in North America, which was partially offset by strong top-line growth in our EMEA and APAC segments. Additionally, we saw lower than expected gross margin performance in EMEA due to changes in business and client sales mix in the quarter and to changes in partner programs. We controlled our selling and administrative expenses; however, these expense savings did not offset the effect of lower sales volumes and gross margins, which led to earnings from operations performance below our expectations,” stated Ken Lamneck, President and Chief Executive Officer. “As we move forward in 2013, we will continue to invest in sales and technical resources in key markets in North America and EMEA, as we believe this is critical to our long-term success. We will also remain focused on managing controllable costs and expect improved operating leverage in the back half of 2013,” added Lamneck.

Net of tax amounts referenced above were computed using the statutory tax rate for the taxing jurisdictions in the operating segment in which the related expenses were recorded.

UPDATED GUIDANCE

The Company currently expects that net sales for the full year 2013 will decline slightly from 2012 due primarily to lower spending by large enterprise clients in North America. The Company also currently expects its second quarter financial results will exhibit similar year to year trends as in the first quarter but that the Company will see improved earnings performance in the back half of 2013 as it begins to realize the benefits of its sales and cost control initiatives. As a result, the Company now expects diluted earnings per share for the full year of 2013 to be between $1.70 and $1.90.

This outlook includes:

• The adverse effect on gross profit of previously announced partner program changes in the Company’s software category, which is estimated to be between $8 and $12 million; and

• an effective tax rate of 36% to 38% for the balance of 2013.

This outlook excludes severance and restructuring expenses incurred during 2013.

CONFERENCE CALL AND WEBCAST

The Company will host a conference call and live web cast today at 5:00 p.m. ET to discuss first quarter 2013 results of operations. A live web cast of the conference call (in listen-only mode) will be accessible online through the investor relations section of the Company’s web site, insight.com, at http://nsit.client.shareholder.com/events.cfm, and a replay of the web cast will be available on the Company’s web site for a limited time following the call. To listen to the live web cast by telephone, call 1-877-402-8904 if located in the U.S., 678-809-1029 for international callers, and enter the access code 30463884.

USE OF NON-GAAP FINANCIAL MEASURES

The non-GAAP financial measures exclude severance and restructuring expenses in 2013 and 2012, a gain on bargain purchase in 2012 and the tax effect of these items. The Company excludes these charges when internally evaluating earnings from operations, tax expense, net earnings and diluted earnings per share for the Company and earnings from operations for each of the Company’s operating segments. These non-GAAP measures are used to evaluate financial performance against budgeted amounts, to calculate incentive compensation, to assist in forecasting future performance and to compare the Company’s results to those of the Company’s competitors. The Company believes that these non-GAAP financial measures are useful to investors because they allow for greater transparency, facilitate comparisons to prior periods and the Company’s competitors’ results and assist in forecasting performance for future periods. These non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures presented by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.
