TEMPE, AZ – May 1, 2019 – Insight Enterprises, Inc. (Nasdaq: NSIT) (the “Company”) today reported financial results for the quarter ended March 31, 2019 compared to the quarter ended March 31, 2018.

In the first quarter of 2019, net sales decreased by 3%, year to year, while gross profit increased 3%, year over year and gross margin increased 90 basis points compared to the first quarter of 2018.  The increase in gross profit and gross margin reflects a higher mix of cloud solutions reported net and higher margin Insight delivered services.  Earnings from operations grew 13%, year over year, with each of our geographic segments generating growth.  

“I am pleased to report we have started the new year with strong earnings performance in the first quarter,” stated Ken Lamneck, President and Chief Executive Officer.  “Our top line results decreased in the first quarter against a tough comparison last year, but we focused on profitable business, growing our services sales and helping our clients migrate to the cloud, which led to strong gross margin expansion in the quarter. At the same time we controlled our expenses, which allowed us to deliver another quarter of double digit earnings growth year over year, with each of our operating segments contributing to these results,” stated Lamneck.

In discussing financial results for the three months ended March 31, 2019 and 2018 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 to non-GAAP measures, the Company refers to such measures as “Adjusted.”  See “Use of Non-GAAP Financial Measures” for additional information.  A tabular reconciliation of financial measures prepared in accordance with GAAP to the non-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 2019, the Company expects to deliver sales growth in the low single digit range compared to 2018.  The Company also expects Adjusted diluted earnings per share for the full year of 2019 to be between $4.75 and $4.85.

This outlook assumes:

• an effective tax rate of 25% to 26% for the balance of 2019;

• capital expenditures of $20 to $25 million for the full year; and

• an average share count for the full year of approximately 36.2 million shares.

This outlook does not reflect the repurchase of any 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 quarter of 2019 and those that may be incurred during the balance of 2019.  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 to non-GAAP diluted earnings per share for the full year 2019 forecast.

Conference Call and Webcast

The Company will host a conference call and live web cast today at 8:00 a.m. ET to discuss first quarter 2019 results of operations.  A live web cast of the conference call (in listen-only mode) will be available on the Company’s web site at http://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, call 1-877-524-8416 if located in the U.S., 412-902-1028 for international callers, and enter the access code 13689759.

Use of Non-GAAP Financial Measures

The non-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 and (ii) the tax effects of severance and restructuring expenses. 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 under the inventory financing facility.  Adjusted return on invested capital (“ROIC”) excludes (i) severance and restructuring expenses, (ii) acquisition related expenses, (iii) loss on sale of the Company’s Russia business, and (iv) the tax effects of each of these items, as applicable.  

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.
