In discussing financial results for the three and nine months ended September 30, 2025 and 2024 in this press release, the Company refers to certain financial measures that are adjusted from the financial results prepared in accordance with United States generally accepted accounting principles (“GAAP”). When referring to non-GAAP measures, the Company refers to them 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, earnings from operations and Adjusted earnings from operations on a consolidated basis and in North America, EMEA and APAC excluding the effects of fluctuating foreign currency exchange rates. In addition, the Company refers to changes in Adjusted diluted earnings per share on a consolidated basis excluding the effects of fluctuating foreign currency exchange rates. These are also considered to be non-GAAP measures. The Company believes providing this information excluding the effects of fluctuating foreign currency exchange rates provides valuable supplemental information to investors regarding its underlying business and results of operations, consistent with how the Company and its management evaluate the Company’s performance. 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 performance measures excluding the effects of fluctuating foreign currency exchange rates should not be considered a substitute for, or superior to, the measures of financial performance prepared in accordance with GAAP.

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 2025, we expect Adjusted diluted earnings per share to be between $9.60 and $9.90. We expect gross profit to be slightly down from 2024 and that our gross margin will be approximately 21%

This outlook assumes:

•interest and other expenses of approximately $85 million;

•an effective tax rate of 25% to 26% for the full year;

•capital expenditures of approximately $25 million; and

•an average share count for the full year of 32.0 million shares, reflecting the settlement of the remaining warrants (the “Warrants”) associated with our convertible senior notes (the “Convertible Notes”) in 2025.

This outlook excludes acquisition-related intangibles amortization expense of approximately $74.4 million, and assumes no acquisition or integration related expenses, transformation or severance and restructuring expenses, net, no significant change in our debt instruments, and no significant change in the macroeconomic environment, whether due to tariffs or otherwise. Due to the inherent difficulty of forecasting some of these types of expenses, which impact net earnings, diluted earnings per share and selling and administrative expenses, the Company is unable to reasonably estimate the impact of such expenses, if any, to net earnings, diluted earnings per share and selling and administrative expenses. Accordingly, the Company is unable to provide a reconciliation of GAAP to non-GAAP diluted earnings per share for the full year 2025 forecast.

CONFERENCE CALL AND WEBCAST

The Company will host a conference call and live webcast today at 9:00 a.m. ET to discuss third quarter 2025 results of operations. A live webcast 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 webcast will be available on the Company’s web site for a limited time following the call. To access the live conference call, please register in advance using the event link on the Company's web site. Upon registering, participants will receive dial-in information via email, as well as a unique registrant ID, event passcode, and detailed instructions regarding how to join the call.

USE OF NON-GAAP FINANCIAL MEASURES

The non-GAAP financial measures are referred to as “Adjusted”. Adjusted earnings from operations, Adjusted net earnings and Adjusted diluted earnings per share exclude (i) severance and restructuring expenses, net, (ii) certain executive recruitment and hiring related expenses, (iii) amortization of intangible assets, (iv) transformation costs, (v) certain acquisition and integration related expenses, (vi) gains and losses from revaluation of acquisition related earnout liabilities, (vii) certain third-party data center service outage related expenses and recoveries, (viii) impairment losses on long lived real estate assets now held for sale, and (ix) the tax effects of each of these items, as applicable. Transformation costs represent costs we are incurring to transform our business to help us achieve our strategic objectives including becoming a leading solutions integrator. 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 net earnings and Adjusted diluted earnings per share also exclude a net loss on revaluation of warrant settlement liabilities, as applicable. Adjusted diluted earnings per share also includes the impact of the benefit from the note hedge where the Company’s average stock price for the period was in excess of $68.32, which was the initial conversion price of the Convertible Notes, which matured in February 2025, as applicable. Adjusted EBITDA excludes (i) interest expense, (ii) income tax expense, (iii) depreciation and amortization of property and equipment, (iv) amortization of intangible assets, (v) severance and restructuring expenses, net, (vi) certain executive recruitment and hiring related expenses, (vii) transformation costs (viii) certain acquisition and integration related expenses, (ix) gains and losses from revaluation of acquisition related earnout liabilities, (x) gains and losses from the revaluation of warrant settlement liabilities, (xi) certain third-party data center service outage related expenses and recoveries, and (xii) impairment losses on long lived real estate assets now held for sale. Adjusted return on invested capital (“ROIC”) excludes (i) severance and restructuring expenses, net, (ii) certain executive recruitment and hiring related expenses, (iii) amortization of intangible assets, (iv) transformation costs, (v) certain acquisition and integration related expenses, (vi) certain third-party data center service outage related expenses and recoveries, (vii) gains and losses from revaluation of acquisition related earnout liabilities, (viii) impairment losses on long lived real estate assets now held for sale, and (ix) the tax effects of each of these items, as applicable.

These non-GAAP measures are used by the Company and its management 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

Statements that are not historical facts, including those related to our expectations about future financial results and the assumptions related thereto, our expectations regarding future expected trends in the IT market and our opportunities for growth, are forward-looking statements. These forward-looking statements are subject to assumptions, risks and uncertainties which could cause actual results or future events to differ materially from such statements. Insight Enterprises, Inc. (the "Company") undertakes no obligation to update publicly or revise any of the forward-looking statements, except as otherwise required by law. More detailed information about forward-looking statements and risk factors is included in today’s press release and discussed in the Company’s most recently filed periodic reports and subsequent filings with the Securities and Exchange Commission. Non-GAAP measures This presentation will reference certain non-GAAP financial information as ‘Adjusted’. A reconciliation of non-GAAP financial measures presented in this document to our actual GAAP results is attached to the back of this presentation and included in the press release issued today, which you may find on the Investor Relations section of our website at investor.insight.com. These non-GAAP measures are used by the Company and its management 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. Constant currency In some instances, the Company refers to changes in net sales, gross profit, earnings from operations and Adjusted earnings from operations on a consolidated basis and in EMEA and APAC, as applicable, excluding the effects of fluctuating foreign currency exchange rates. In addition, the Company refers to changes in Adjusted diluted earnings per share on a consolidated basis excluding the effects of fluctuating foreign currency exchange rates. These are also considered to be non-GAAP measures. The Company believes providing this information excluding the effects of fluctuating foreign currency exchange rates provides valuable supplemental information to investors regarding its underlying business and results of operations, consistent with how the Company and its management evaluate the Company’s performance. 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.
