Exhibit 99.1

FOR IMMEDIATE RELEASE NASDAQ: NSIT

INSIGHT ENTERPRISES, INC. REPORTS SECOND QUARTER 2018 RESULTS AND INCREASES FULL YEAR 2018 GUIDANCE

TEMPE, AZ – August 1, 2018 – Insight Enterprises, Inc. (NASDAQ: NSIT) (the “Company”) today reported strong financial results for the quarter ended June 30, 2018 compared to the quarter ended June 30, 2017.

• Diluted earnings per share of $1.44 increased 30% year over year

• Adjusted diluted earnings per share of $1.45 increased 27% year over year

• Cash flows provided by operations in the first half of 2018 were $351.0 million compared to cash used in operations of $99.3 million in the first half of 2017

In the second quarter of 2018, consolidated net sales increased 9% and consolidated gross profit increased 5% year over year. These results are primarily driven by continued strong growth in the hardware category as a result of the ongoing device refresh cycle as well as a 22% increase in services sales year over year, which includes professional services as well as cloud and maintenance offerings. Earnings from operations (“EFO”) increased 7% year over year and EFO margin was 4.1%.

The Company also announced that it has acquired Cardinal Solution Group. Inc. (“Cardinal”) effective August 1, 2018. Cardinal is a digital solutions provider based in Cincinnati, Ohio with expertise in mobile applications development, IOT and cloud enabled business intelligence. Cardinal will complement the capabilities the Company has been building within the digital innovation solution area, following the acquisitions of BlueMetal and Ignia in 2015 and 2016, respectively. The Company expects the acquisition to be neutral to earnings from operations for the balance of 2018, including projected intangible amortization.

“We are pleased with our top and bottom line financial results in the second quarter and with our team’s execution in optimizing working capital in the business, which led to Adjusted free cash flow of more than $300 million in the first half of the year,” stated Ken Lamneck, President and Chief Executive Officer. “Our strategy to grow organically while consistently driving operational efficiency across the business allows us to invest for the long term, including strategic acquisitions like Cardinal that will bring scale and reach to our already strong Digital Innovations solution area,” stated Lamneck.

As services have become a larger portion of the Company’s consolidated net sales, beginning with our results of operations for the year ended December 31, 2017, the Company began reporting net sales from the provision of services and the related costs of goods sold separately from net sales of products and the related costs of goods sold. The Company continued this presentation in the three and six months ended June 30, 2018, and expects to continue this presentation in future periods. For comparability purposes, net sales and costs of goods sold for the 2017 periods have been expanded to conform to the current year presentation. These changes in presentation had no effect on previously reported total net sales, total costs of goods sold or gross profit amounts.

In conjunction with these changes in presentation, because fees earned from activities reported net are now considered services revenues, the Company reclassified certain revenue streams for which the Company acts as the agent in the transaction to net sales from services. Previously, the Company included these net revenue streams within its software and, to a lesser extent, hardware sales mix categories based on the type of product being sold (e.g., fees earned for the sale of software maintenance and certain software licenses were included in software sales and fees earned for the sale of certain third-party provided training and warranty services were included in hardware sales when the Company historically disclosed and analyzed its sales mix). For comparability purposes, the Company’s sales mix among its hardware, software and services categories for the three and six months ended June 30, 2017, as presented in the Financial Summary Table in this press release, has been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported total net sales amounts.

In discussing financial results for the three months ended June 30, 2018 and 2017 in this press release, the Company refers to certain financial measures that are not prepared in accordance with United States generally accepted accounting principles (“GAAP”). When referring tonon-GAAP measures, the Company refers to such measures as “Adjusted.” See “Use ofNon-GAAP Financial Measures” for additional information. A tabular reconciliation of financial measures prepared in accordance with GAAP to thenon-GAAP financial measures is included at the end of this press release.

In some instances the Company refers to changes in net sales, gross profit and earnings from operations on a consolidated basis and in North America, EMEA and APAC excluding the effects of fluctuating foreign currency exchange rates. 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 weighted average translation rate for the current period.

The tax effect of Adjusted amounts referenced herein were computed using the statutory tax rate for the taxing jurisdictions in the operating segment in which the related expenses were recorded, adjusted for the effects of valuation allowances on net operating losses in certain jurisdictions.

GUIDANCE

For the full year 2018, the Company expects to deliver sales growth in the high single to low double digit range compared to 2017. The Company is also increasing its Adjusted diluted earnings per share outlook for the full year of 2018 to be between $4.50 and $4.60.

This outlook assumes:

• an effective tax rate of between 26% and 27% for the balance of 2018;

• capital expenditures of $15 to $20 million for the full year; and

• an average share count for the full year of approximately 36.0 million shares.

This outlook does not reflect the repurchase of any additional shares under the Company’s currently authorized share repurchase program, assumes no current year acquisition-related expenses and excludes severance and restructuring expenses incurred during the first half of 2018 and those that may be incurred during the balance of 2018. Due to the inherent difficulty of forecasting these types of expenses, which impact net earnings and diluted earnings per share, the Company is unable to reasonably estimate the related impact of such expenses, if any, to net earnings and diluted earnings per share. Accordingly, the Company is unable to provide a reconciliation of GAAP tonon-GAAP diluted earnings per share for the full year 2018 forecast.

CONFERENCE CALL AND WEBCAST

The Company will host a conference call and live web cast today at 9:00 a.m. ET to discuss second quarter 2018 results of operations. A live web cast of the conference call (in listen-only mode) will be available on the Company’s web site athttp://investor.insight.com/, 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, call1-877-402-8904 if located in the U.S.,678-809-1029 for international callers, and enter the access code 4892118.

USE OFNON-GAAP FINANCIAL MEASURES

Thenon-GAAP financial measures are referred to as “Adjusted.” Adjusted consolidated earnings from operations, Adjusted consolidated net earnings and Adjusted diluted earnings per share exclude (i) severance and restructuring expenses, (ii) certain acquisition-related expenses, and (iii) the tax effects of each of these items, as applicable. The Company excludes these items 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. Adjusted free cash flow is the Company’s net cash provided or used by operating activities adjusted for (i) purchases of property and equipment and (ii) the net borrowings or repayments on the inventory financing facility. Adjusted return on invested capital (“ROIC”) excludes (i) severance and restructuring expenses, (ii) certain acquisition-related expenses, and (iii) a loss on sale of the Company’s Russia business in the 2017 period.

Thesenon-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 thesenon-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. Thesenon-GAAP financial measures are not prepared in accordance with GAAP and may be different fromnon-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.
