TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS

This report contains “forward-looking statements” within the meaning of the federal securities laws. All statements other than statements of historical fact are forward-looking statements. These statements relate to analyses and other information, which are based on forecasts of future results or events and estimates of amounts not yet determinable. These statements also relate to our future prospects, growth, developments, and business strategies. We claim the protection of The Private Securities Litigation Reform Act of 1995 for all forward-looking statements in this report.

These forward-looking statements are identified by the use of terms and phrases such as “anticipate,” “assume,” “believe,” “estimate,” “expect,” “goal,” “intend,” “plan,” “potential,” “predict,” “project,” “target,” and similar terms and phrases or future or conditional verbs such as “could,” “may,” “should,” “will,” and “would.” However, these words are not the exclusive means of identifying such statements. Although we believe that our plans, intentions, and other expectations reflected in or suggested by such forward-looking statements are reasonable, we cannot assure you that we will achieve those plans, intentions, or expectations. All forward-looking statements are subject to risks and uncertainties that may cause actual results or events to differ materially from those that we expected.

Important factors that could cause actual results or events to differ materially from our expectations, or cautionary statements, are disclosed under the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included elsewhere in this report and in our subsequent Quarterly Reports on Form 10-Q and our other US Securities and Exchange Commission (“SEC”) filings and public communications. These factors include, among others:

•relationships with our vendor partners and wholesale distributors and the terms of their agreements;

•the ability of vendor partners, wholesale distributors, and third-party providers to fulfill their responsibilities and commitments and our reliance on certain key vendor partners and wholesale distributors;

•our dependence on the continued innovations in technology by our vendor partners;

•the use or capabilities of artificial intelligence and the challenges related to its adoption;

•substantial competition that could reduce our market share;

•the continuing development, maintenance, and operation of our information technology (“IT”) systems;

•potential breaches of data security and failure to protect our IT systems from cybersecurity threats;

•potential failures to provide high-quality services to our customers;

•potential losses of any key personnel, significant increases in labor costs, or ineffective workforce management;

•potential service failures or disruptions related to outsourcing arrangements with certain business processes;

•potential adverse occurrences at one of our primary facilities or third-party data centers, including as a result of climate change;

•increases in the cost of commercial delivery services or disruptions of those services;

•exposure to accounts receivable and inventory risks;

•the costs and risks associated with, and the successful and timely execution and effects of, strategic investments or acquisitions or entry into joint ventures, including our ability to align our investment efforts with our strategic goals;

•the volatility and rapidly changing state of the technology industry, and any resulting volatility in the market price of our stock;

•the costs and risks associated with, and the successful and timely execution and effects of, our existing and any future business opportunities, expansions, initiatives, strategies, investments, and plans;

•fluctuations in foreign currency and our operating results;

•global and regional economic and political conditions, including the impact of inflationary pressures and the level of interest rates;

•decreases, delays, or changes in spending on technology products and services, including impacts of adverse changes in government spending and funding policies, federal procurement policies, and US government shutdowns;

•potential disruptions in the supply of products from our suppliers, including capacity limitations and cost increases resulting from heightened demand related to artificial intelligence workloads;

•potential failures to comply with public sector contracts or applicable laws and regulations;

•current and future legal proceedings, investigations, and audits, including intellectual property infringement claims;

•potential failure to comply with complex and evolving laws and regulations applicable to our operations or to meet sometimes conflicting stakeholder expectations on environmental sustainability and corporate responsibility matters;

•our level of indebtedness and the obligations imposed by agreements and instruments relating to our indebtedness;

•fluctuations in the market price and trading volumes of our common stock and changes in, or the discontinuation of, our share repurchase program or dividend payments; and

•other risk factors or uncertainties identified from time to time in our filings with the SEC.

All written and oral forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by those cautionary statements as well as other cautionary statements that are made from time to time in our other

SEC filings and public communications. You should evaluate all forward-looking statements made in this report in the context of these risks and uncertainties.

We caution you that the important factors referenced above may not reflect all of the factors that could cause actual results or events to differ from our expectations. In addition, we cannot assure you that we will realize the results or developments we expect or anticipate or, even if substantially realized, that they will result in the consequences or affect us or our operations in the way we expect. The forward-looking statements included in this report are made only as of the date hereof or, with respect to any documents incorporated by reference, available at the time such document was prepared or filed with the SEC. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.
