Cdw Corp,
Fiscal Year 2024.

Interest expense, net decreased $12 million, or 5.3%, primarily due to increased interest income earned on higher average cash balances. Income tax expense was $358 million for the year ended December 31, 2024, compared to $346 million for the year ended December 31, 2023. The effective income tax rate, expressed by calculating income tax expense as a percentage of Income before income taxes, was 24.9% and 23.9% for 2024 and 2023, respectively. The higher effective income tax rate for the year ended December 31, 2024 as compared to the prior year was primarily attributable to lower excess tax benefits on equity-based compensation. 27

Cash conversion cycle18 17 (1)Represents the rolling three-month average of the balance of the current portion of Accounts receivable, net at the end of the period, divided by average daily Net sales for the same three-month period. Also incorporates components of other miscellaneous receivables. (2)Represents the rolling three-month average of the balance of Merchandise inventory at the end of the period divided by average daily Cost of sales for the same three-month period. (3)Represents the rolling three-month average of the combined balance of the current portion of Accounts payable-trade, excluding cash overdrafts, and Accounts payable-inventory financing at the end of the period divided by average daily Cost of sales for the same three-month period. The cash conversion cycle increased to 18 days at December 31, 2024, compared to 17 days at December 31, 2023. The overall increase was primarily driven by an increase in DSO due to multi-year transactions and timing of collections. This was partially offset by an increase in DPO due to multi-year transactions and timing of payments. If customers continue to shift their software purchases to multi-year arrangements, unbilled receivables will continue to grow, which is offset by the growth in accounts payable to match the timing of collections due from customers with the payments due to vendors. Netted down revenue results in an increase in both DSO and DPO as the corresponding receivables and payables reflect the gross amounts due from customers and due to vendors while the corresponding sales and cost of sales are reflected on a net basis within Net sales.

Key Business Metrics We monitor a number of financial and non-financial measures and ratios on a regular basis in order to track the progress of our business and make adjustments as necessary. We believe that the most important of these measures and ratios include average daily sales, Gross profit, Net income, Operating income, Operating income margin, Non-GAAP operating income, Non-GAAP operating income margin, Non-GAAP net income, Net sales on a constant currency basis, Net income per diluted share, Non-GAAP net income per diluted share, Free cash flow, Adjusted free cash flow, Cash and cash equivalents, cash conversion cycle and debt levels including available credit. These measures and ratios are closely monitored by management, so that actions can be taken, as necessary, in order to achieve financial objectives. In this section, we present Non-GAAP operating income, Non-GAAP operating income margin, Non-GAAP net income, Non-GAAP net income per diluted share, Net sales on a constant currency basis, Free cash flow and Adjusted free cash flow, which are non-GAAP financial measures. We believe Non-GAAP operating income, Non-GAAP operating income margin, Non-GAAP net income, Non-GAAP net income per diluted share and Net sales on a constant currency basis provide analysts, investors and management with helpful information regarding the underlying operating performance of our business, as they remove the impact of items that management believes are not reflective of underlying operating performance. Management uses these measures to evaluate period-over-period performance as management believes they provide a more comparable measure of the underlying business. We also present Free cash flow and Adjusted free cash flow as we believe these measures provide more information regarding our liquidity and capital resources. Certain non-GAAP financial measures are also used to determine certain components of performance-based compensation. For the definitions of Non-GAAP measures and reconciliations to the most directly comparable US GAAP measure, see "Results of Operations - Non-GAAP Financial Measure Reconciliations." 26

Seasonality While we have not historically experienced significant seasonality throughout the year, sales in our Corporate segment, which primarily serves US private sector business customers with more than 250 employees, have historically been higher in the fourth quarter than in other quarters due to customers spending their remaining technology budget dollars at the end of the year. Additionally, sales in our Public segment have historically been higher in the third quarter than in other quarters primarily due to the buying patterns of the federal government and education customers. Since 2020, we have experienced variability compared to historic seasonality trends. Seasonality by channel is expected to continue to be different than historical experience.

(2)The change is primarily due to higher sales activity during the fourth quarter 2023, partially offset by collection performance. (3)The change is primarily due to higher sales activity during the fourth quarter 2023 and timing of payments. (4)The change is primarily due to lower contract assets and vendor receivables, partially offset by decreased accrued compensation and lower contract liabilities in 2023. In order to manage our working capital and operating cash needs, we monitor our cash conversion cycle, defined as days of sales outstanding in accounts receivable plus days of supply in inventory minus days of purchases outstanding in accounts payable, based on a rolling three-month average. Components of our cash conversion cycle are as follows: December 31,

Financing Activities Net cash used in financing activities decreased $3 million in 2023 compared to 2022. The decrease was primarily driven by lower repayments on long-term debt, partially offset by share repurchases in 2023 with no similar activity in 2022, decreased activity within our inventory financing arrangements and increased dividend payments. For additional information regarding the inventory financing and debt activities, see Note 7 (Inventory Financing Agreements) and Note 9 (Debt) to the accompanying Consolidated Financial Statements. 34

Overview CDW Corporation ("Parent"), a Fortune 500 company and member of the S&P 500 Index, is a leading multi-brand provider of information technology ("IT") solutions to business, government, education and healthcare customers in the United States ("US"), the United Kingdom ("UK") and Canada. Our broad array of offerings ranges from discrete hardware and software products to integrated IT solutions and services that include on-premise and cloud capabilities across hybrid infrastructure, digital experience and security. We have three reportable segments: Corporate, Small Business and Public. Our Corporate segment primarily serves US private sector business customers with more than 250 employees. Our Small Business segment primarily serves US private sector business customers with up to 250 employees. Our Public segment is comprised of government agencies and education and healthcare institutions in the US. We also have two other operating segments: CDW UK and CDW Canada, each of which do not meet the reportable segment quantitative thresholds and, accordingly, are included in an all other category ("Other"). We are vendor, technology and consumption model unbiased, with a solutions portfolio including more than 100,000 products and services from more than 1,000 leading and emerging brands. Our solutions are delivered in physical, virtual and cloud-based environments through approximately 10,900 customer-facing coworkers, including sellers, highly-skilled specialists and engineers. We are a leading sales channel partner for many original equipment manufacturers, software publishers, cloud providers (collectively, our "vendor partners") and wholesale distributors, whose products we sell or include in the solutions we offer. We provide our vendor partners with a cost-effective way to reach customers and deliver a consistent brand experience through our established end-market coverage, technical expertise and extensive customer access. We may sell all or only select products that our vendor partners offer. Each vendor partner agreement provides for specific terms and conditions, which may include one or more of the following: product return privileges, price protection policies, purchase discounts and vendor incentive programs, such as purchase or sales rebates and cooperative advertising reimbursements. We also resell software for major software publishers. Our agreements with software publishers allow the end-user customer to acquire software or licensed products and services. In addition to helping our customers determine the best software solutions for their needs, we help them manage their software agreements, including warranties and renewals. A significant portion of our advertising and marketing expenses are reimbursed through cooperative advertising programs with our vendor partners. These programs are at the discretion of our vendor partners and are typically tied to sales or other commitments to be met by us within a specified period of time. For a discussion of results for the year ended December 31, 2023, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission on February 26, 2024.

Trends and Key Factors Affecting our Financial Performance We believe the following key factors may have a meaningful impact on our business performance, influencing our ability to generate sales and achieve our targeted financial and operating results: •General economic conditions are a key factor affecting our results as they can impact our customers' willingness and ability to spend on information technology. Macroeconomic uncertainty persists as a result of the inflationary environment and the corresponding level of interest rates driven by monetary policy. The uncertainty in the current economic environment resulted in, and may continue to result in, a delay, pause or reduction of investments in technology by our customers. •Customers are evaluating the complex technology landscape in order to balance priorities and focus on solutions that lead to business optimization, cost management and security risk management, resulting in a more measured approach to their IT spending. We have orchestrated solutions by leveraging security, software and hybrid and cloud offerings to help customers achieve their objectives. •Changes and uncertainty related to spending policies, budget priorities, timing and funding levels, including stimulus packages, are key factors influencing the purchasing levels of government, healthcare and education customers. As the duration and ongoing impact of current economic conditions remain uncertain, current and future budget priorities and funding levels for government, healthcare and education customers may be adversely affected, leading to lower IT spend. •Technology trends drive customer purchasing behaviors in the market. Current technology trends are focused on delivering greater flexibility and efficiency, as well as designing and managing IT securely. These trends are driving customer adoption of cloud, artificial intelligence, software defined architectures and hybrid on-premise and off-premise combinations. The trends are further driven by the evolution of the IT consumption model to more "as a service" offerings, including software as a service and infrastructure as a service, in addition to ongoing managed and professional service arrangements. Technology trends are likely to evolve as customers prioritize spend that will produce the most important outcomes for their business.

Liquidity and Capital Resources Overview We finance our operations and capital expenditures with cash from operations and borrowings under our variable rate senior unsecured revolving loan facility (the "Revolving Loan Facility"). As of December 31, 2024, we had $1.2 billion of availability for borrowings under our Revolving Loan Facility. Our liquidity and borrowing plans are established to align with our financial and strategic planning processes and ensure we have the necessary funding to meet our operating commitments, which primarily include the purchase of inventory, payroll and general expenses. We also take into consideration our overall capital allocation strategy, which includes dividend payments, assessment of debt levels, acquisitions and share repurchases. We believe we have adequate sources of liquidity and funding available for at least the next year; however, there are a number of factors that may negatively impact our available sources of funds. The amount of cash generated from operations will be dependent upon factors such as the successful execution of our business plan, general economic conditions and working capital management. Our material contractual obligations consist of debt and related interest payments and operating leases. For additional information regarding future maturities of debt and operating leases, see Note 8 (Debt) and Note 11 (Leases), respectively, to the accompanying Consolidated Financial Statements included in Part II, Item 8 of this report.

Share Repurchase Program During 2024, we repurchased 2.4 million shares of our common stock for $500 million under the previously announced share repurchase program. For additional information about our share repurchase program, refer to Note 12 (Stockholders' Equity) to the accompanying Consolidated Financial Statements included in Part II, Item 8 of this report.

Dividends A summary of 2024 dividend activity for our common stock is as follows: Dividend AmountDeclaration DateRecord Date Payment Date $0.620 February 6, 2024February 26, 2024March 12, 2024

determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together. For contracts consisting of multiple performance obligations, the total transaction price is allocated to each performance obligation based upon its standalone selling price. Judgment is required to determine the standalone selling price for each distinct performance obligation. For certain types of performance obligations, we use a combination of methods to estimate the standalone selling price based on recent transactions. When evidence from recent transactions is not available to confirm that the prices are representative of the standalone selling price, an expected cost plus margin approach is used. Additional judgment is required in determining whether we are the principal, and report revenues on a gross basis, or agent, and report revenues on a net basis. For each identified performance obligation in a transaction, we evaluate the facts and circumstances present to determine whether or not we control the specified good or service prior to transfer to the customer. This evaluation includes, but is not limited to, assessing indicators such as whether: (i) we are primarily responsible for fulfilling the promise to provide the specified goods or service, (ii) we have inventory risk before the specified good or service has been transferred to a customer and (iii) we have discretion in establishing the price for the specified good or service. When the evaluation indicates we control the specified good or service prior to transfer to the customer, we are acting as a principal. When the evaluation indicates we do not control the specified good or service prior transfer to the customer, we are acting as an agent. The nature of our contracts give rise to variable consideration, primarily in the form of volume rebates and sales returns and allowances. We estimate variable consideration at the most likely amount to which we expect to be entitled. The estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based on an assessment of our anticipated performance and all information that is reasonably available. We recognize revenue from performance obligations when, or as, the customer obtains control over the specified good or service. That is, when the customer has the ability to direct the use of and obtain substantially all of the benefits from the good or service. For the sale of hardware, this is generally upon delivery to the customer. As a result, we perform an analysis to estimate the amount of Net sales in-transit at the end of the period and adjust revenue and the related costs to reflect only what has been delivered to the customer. This analysis requires judgment whereby we perform an analysis of the estimated number of days of sales in-transit to customers at the end of each reporting period based on a weighted-average analysis of commercial delivery terms that include drop-shipment arrangements. Changes in delivery patterns may result in a different number of business days estimated to make this adjustment. For the sale of professional services, we recognize the revenue over time given that our customers simultaneously receive and consume the benefits from these services as they are performed. Depending on the arrangement, revenues from fixed fee contracts on professional services are recognized using an input method, which requires management to make estimates regarding the amount of resources required for each engagement in order to satisfy the performance obligation.

Goodwill Goodwill is allocated to reporting units expected to benefit from the business combination. Goodwill is subject to periodic testing for impairment at the reporting unit level on an annual basis during the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset may be impaired. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition or sale or disposition of a significant portion of a reporting unit. We may elect to utilize a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. As part of our qualitative assessment, judgment is required in weighing the effect of various positive and negative factors that may affect the fair value. We consider various factors, including the excess of fair value over carrying value from the last quantitative test, macroeconomic conditions, industry and market considerations, the projected financial performance and actual financial performance compared to prior year projected financial performance. If we elect to bypass the qualitative assessment, or if indicators of impairment exist, a quantitative impairment test is performed. As part of the quantitative assessment, application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units and determination of the fair value of each reporting unit. Fair value of a reporting unit is determined by using a weighted combination of an income approach and a market approach, as this combination is considered the most indicative of our fair value in an orderly transaction between market participants. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, determination of our weighted average cost of capital, future market conditions and profitability of future business strategies. The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results, market conditions and other factors. Changes in these estimates and assumptions could materially affect the 36 determination of fair value and goodwill impairment for each reporting unit. However, since our last quantitative analysis, our past estimates of fair value would not have indicated an impairment when revised to include subsequent years' actual results. We completed our annual impairment analysis during the fourth quarter of 2024. We performed a qualitative analysis for all reporting units and concluded that it was more likely than not that the fair values of all reporting units exceeded their respective carrying values and, therefore, did not result in an impairment. The last quantitative analysis was performed in the fourth quarter of 2023, and it was determined that the fair values of each reporting unit substantially exceeded their carrying values, resulting in no goodwill impairment.

Recent Accounting Pronouncements See the information set forth in Note 2 (Recent Accounting Pronouncements) to the accompanying Consolidated Financial Statements included in Part II, Item 8 of this report.

Social, ethical and safety issues relating to the use of new and evolving technologies such as artificial intelligence-based technologies, including generative AI in our hardware, software and service offerings, as well as in our internal platforms, may result in reputational harm and liability. Certain of the hardware, software and services we offer increasingly utilize AI, and, as with many innovations, AI presents risks and challenges that could affect its adoption, and therefore our business. If we use, enable or offer solutions that draw controversy due to their perceived or actual impact on society, we may experience brand or reputational harm, competitive harm and/or legal liability. Increased focus and potential government regulation of AI may also increase the burden and cost of compliance in this area, subjecting us to brand or reputational harm, competitive harm and/or legal liability. Failure to address AI issues by us or others in our industry could undermine public confidence in AI and slow adoption of AI in our products and services. Additionally, the development, adoption and use of AI by us or our vendor partners could result in unintended consequences, including exposing us to additional risks related to cybersecurity, privacy and data security, such as the risk of increased vulnerability to cybersecurity threats and exposure or theft of proprietary or sensitive information (which could result in such information being made available to our competitors and other members of the public), impacts to the stability of our operations, the generation of factually incorrect or biased outputs, reliance on outdated or unverified data, potential intellectual property infringements, the inability to protect generated content while facing unfavorable licensing terms and the inability to attract and retain key personnel. AI technologies are complex and rapidly evolving, and we face significant competition in the market and from other companies regarding such technologies. Further, the responsible development and deployment of AI requires ongoing investment in research, development and governance, which could adversely affect our results of operation or cash flows.

The success of our business depends on the continuing development, maintenance and operation of our information technology systems. Our success is dependent on the accuracy, proper utilization and continuing operation, maintenance and development of our information technology systems, including our business systems, such as our sales, customer management, financial and accounting, marketing, purchasing, warehouse management, e-commerce and mobile systems, as well as our operational platforms, including voice and data networks and power systems, which may include third-party hosted systems or systems that may utilize cloud technologies outside of our control. The quality and our utilization of the information generated by our information technology systems, and our success in implementing new systems and upgrades, including our transformation initiatives, could adversely affect, among other things, our ability to: •conduct business with our customers, including delivering services and solutions to them; •provide the means to effectively manage global operations across time zones; •keep pace with changes and innovation and compete effectively; •effectuate comprehensive and reliable data collection, maintenance and governance; •manage our inventory, accounts receivable and accounts payable; •support planned growth in services and solutions and continued evolution of the business; •purchase, sell, ship and invoice our hardware and software products and provide and invoice our services efficiently and on a timely basis; •maintain an effective internal control environment around our financial close process and regulatory reporting requirements;

We could be exposed to additional risks if we continue to make strategic investments or acquisitions or enter into alliances. We may continue to pursue transactions, including strategic investments, acquisitions or alliances, in an effort to extend or complement our existing business. These types of transactions involve numerous business risks, including finding suitable transaction partners and negotiating terms that are acceptable to us, the diversion of management's attention from other business priorities, extending our product or service offerings into areas in which we have limited experience, entering into new geographic markets, an acquisition target's differing or inadequate cybersecurity and data protection controls, the potential loss of key coworkers or business relationships and successfully integrating acquired businesses. There can be no assurance that the intended benefits of our investments, acquisitions and alliances will be realized, or that those benefits will offset these numerous risks or other unforeseen factors, any of which could adversely affect our business, results of operations or cash flows. In addition, our financial results could be adversely affected by financial adjustments required by generally accepted accounting principles in the United States of America ("US GAAP") in connection with these types of transactions where significant goodwill or intangible assets are recorded. To the extent the value of goodwill or identifiable intangible assets becomes impaired, we may be required to incur material charges relating to the impairment of those assets. Our future operating results may fluctuate significantly, which may result in volatility in the market price of our stock and could impact our ability to operate our business effectively. We may experience significant variations in our future quarterly results of operations. These fluctuations may cause the market price of our common stock to be volatile and may result from many factors, including the state of the technology industry in general, shifts in demand and pricing for hardware, software and services, the introduction of new products or upgrades. Further, if our customers' businesses are adversely affected by global or regional economic conditions such as cost inflation or rising interest rates, they may delay or reduce purchases from us, which could adversely affect our results of operations. Our operating results are also highly dependent on Gross profit. Our Gross profit fluctuates due to numerous factors, some of which may be outside of our control, including general macroeconomic conditions including inflation; pricing pressures; 15 changes in product costs from our vendor partners; the availability of price protection, purchase discounts and incentive programs from our vendor partners; changes in product, order size and customer mix; the risk of some items in our inventory becoming obsolete; increases in product and delivery costs that we cannot pass on to customers; and general market and competitive conditions. In addition, our cost structure is based, in part, on anticipated sales and gross margins. Therefore, we may not be able to adjust our cost structure quickly enough to compensate for any unexpected sales or gross margin shortfall, and any such inability could have an adverse effect on our business, results of operations or cash flows.

The acceleration of amounts outstanding under our senior credit facilities would likely trigger an event of default under our existing indentures. If the lenders under our senior credit facilities accelerate the repayment of borrowings, we may not have sufficient assets to repay our senior credit facilities and our other indebtedness or the ability to borrow sufficient funds to refinance such indebtedness. Even if we were able to obtain new financing, it may not be on commercially reasonable terms, or terms that are acceptable to us.

Breaches of data security and the failure to protect our information technology systems from cybersecurity threats could adversely impact our business. Our business involves the handling, storage and transmission of proprietary information and sensitive or confidential data, including personal information of coworkers, customers, partners and others, which we must do in compliance with applicable law. In connection with our services business, some of our coworkers have access to our customers' confidential data and other information. Additionally, third parties, such as data center colocation and hosted solution partners, provide services to us and also provide services as a component of our services delivery to customers and to customer systems. These third parties or others that are a part of our supply chain could also be a source of security risk in the event of a failure to protect their own products, security systems and infrastructure and we may not be able to control the manner in which these third parties respond to any security breach. We have privacy and data security policies, practices and controls in place that are designed to prevent security breaches; however, as newer technologies evolve, as more business is conducted over the internet and remotely, as we acquire more business operations from targets with differing or inadequate cybersecurity and data protection controls and as the portfolio of the service providers we exchange confidential information, software and/or hardware with expands, we have been subject to breaches in security and are increasingly likely to be exposed to risks from breaches in security, including those arising from human error, negligence or mismanagement or from illegal or fraudulent acts, such as cyberattacks. We, and some third parties upon which we rely, regularly experience malicious attacks and other attempts to gain unauthorized access to our systems, and attacks against us by state-sponsored organizations and nation-states may increase during periods of intense diplomatic or armed conflicts. Further, security breaches may go undetected and persist in our environments for extended periods. Although we have not experienced a material security breach to date, the evolving and escalating nature of cybersecurity threats, in light of new and sophisticated methods used by criminals and cyberterrorists, state-sponsored 12 organizations and nation-states, including computer viruses, malware, ransomware, phishing, misrepresentation, social engineering and forgery, make it increasingly challenging to anticipate, detect and defend against these threats. We and our third-party partners have implemented various security controls to meet compliance and privacy requirements while defending against these evolving security threats. However, breaches in security could expose us, our supply chain, our customers or other individuals to significant disruptions and a risk of public disclosure, loss or misuse of confidential data. Security breaches could result in legal claims or proceedings, liability or regulatory penalties under laws protecting the privacy of personal information (including those under the European Union General Data Protection Regulation and the California Privacy Rights Act), significant remediation costs as well as the loss of partners and existing or potential customers and, ultimately, damage to our brand and reputation and adversely impact our business. While we maintain insurance coverages that are intended to address certain aspects of data security, such insurance may be insufficient to cover all losses or all types of claims that may arise, and may not continue to be available to us on economically reasonable terms or at all. Moreover, media or other reports of perceived vulnerabilities in our network security or perceived lack of security within our environment, even if inaccurate, could materially adversely impact our reputation and business. The cost and operational consequences of implementing further data protection measures could also be material. Such breaches, costs and consequences could adversely affect our business, results of operations or cash flows. If we or our third-party service providers fail to provide high-quality services to our customers, our reputation, brand, business, results of operations or cash flows could be adversely affected. Our services include professional services, managed services, warranties, configuration services, partner services and telecom services. Additionally, we deliver and manage mission critical software, systems and network solutions for our customers. We also offer certain services, such as implementation and installation services and repair services, to our customers through various third-party service providers engaged to perform these services on our behalf. If we or our third-party service providers fail to provide high-quality services to our customers or such services result in an unplanned disruption of our customers' businesses, this could, among other things, result in legal claims and proceedings and liability for us. Moreover, as we expand our services and solutions business and provide increasingly complex services and solutions, we may be exposed to additional operational, regulatory and other risks. We also could incur liability for failure to comply with the rules and regulations applicable to the new services and solutions we provide to our customers. If any of the foregoing were to occur, our reputation with our customers, our brand and our business, results of operations or cash flows could be adversely affected. If we lose any of our key personnel, are unable to attract and retain the talent required for our business, our labor costs significantly increase or our approach to workforce management, inclusive of outsourcing, is ineffective, our business could be disrupted and our financial performance could suffer.

Business and Operational Risks Our business depends on our vendor partner and wholesale distributor relationships and the terms of the agreements governing those relationships. Our solutions portfolio includes products and services from OEMs, software publishers and cloud providers. We are authorized by these vendor partners to sell all or some of their products and services via direct marketing activities. Our authorization with each vendor partner is subject to specific terms and conditions regarding such things as sales channel restrictions, product return privileges, services performance commitments, price protection policies, purchase discounts and vendor partner programs and funding, including purchase rebates, sales volume rebates, purchasing incentives and cooperative advertising reimbursements. However, our contracts with our vendor partners are primarily short-term and many of these arrangements are terminable upon notice by either party. A reduction in vendor partner programs or funding or our failure to timely react to changes in vendor partner programs or funding could have an adverse effect on our business, results of operations or cash flows. In addition, a reduction in the amount or a change in the terms of credit granted to us by our vendor partners could increase our need for, and the cost of, working capital and could have an adverse effect on our business, results of operations or cash flows. From time to time, vendor partners may terminate or limit our right to sell some or all of their products or change the terms and conditions or reduce or discontinue the incentives that they offer us. For example, there is no assurance that, as our vendor partners continue to sell directly to end users and through resellers, they will not limit or curtail the availability of their products to solutions providers like us. Any such termination or limitation or the implementation of such changes could have a negative impact on our business, results of operations or cash flows. We purchase the products included in our portfolio both directly from our vendor partners and from wholesale distributors. A significant portion of our sales are derived from products manufactured by Apple, Cisco, Dell Technologies, HP Inc., Lenovo and Microsoft. In addition, purchases from two wholesale distributors, Ingram Micro and TD SYNNEX, represent over 25% of our total purchases. The loss of, or change in business relationship with, any of these or any other wholesale distributors or key vendor partners, or the diminished availability of their products, including due to backlogs for their products, could reduce the supply and impact the cost of products we sell and negatively impact our competitive position. Further, the sale, spin-off or combination of any of our key vendor partners or wholesale distributors and/or certain of their business units, including any such sale to or combination with a vendor with whom we do not currently have a commercial relationship or whose products we do not sell, or our inability to develop relationships with new and emerging vendors and vendors that we have not historically represented in the marketplace, could have an adverse impact on our business, results of operations or cash flows. Our sales are dependent on continued innovations in technology by our vendor partners and the competitiveness of their offerings, and our ability to partner with new and emerging technology providers. The technology industry is characterized by rapid innovation and the frequent introduction of new and enhanced hardware, software and services, such as cloud-based and other "as a service" solutions, hyper-converged infrastructure, embedded software solutions and solutions that incorporate artificial intelligence. We have been and will continue to be dependent on innovations in technology, as well as the adoption of those innovations by customers. Also, customers may delay spending while they evaluate new technologies. A decrease in the rate of innovation, a lack of adoption of innovations by our customers or delays in technology spending by our customers, could have an adverse effect on our business, results of operations or cash flows. In addition, if we are unable to anticipate and expand our capabilities to keep pace with changes in technology and new hardware, software and services, for example by providing the appropriate training to our account managers, specialists and engineers to enable them to effectively sell and deliver such new offerings to customers, our business, results of operations or cash flows could be adversely affected. We also are dependent upon our vendor partners for the development and marketing of hardware, software and services to compete effectively with hardware, software and services of vendors whose products and services we do not currently offer or that we are not authorized to offer in one or more customer channels. To the extent that a vendor's offering that is in high demand is not available to us for resale in one or more customer channels, and there is not a competitive offering from another vendor that we are authorized to sell in such customer channels, our business, results of operations or cash flows could be adversely impacted. Issues relating to the use or capabilities of artificial intelligence, including social, ethical and safety issues, in hardware, software and services offerings may result in reputational harm, liability or increased costs.

Macroeconomic and Industry Risks Global and regional economic and political conditions may have an adverse impact on our business. Political events, trade and other international disputes, geopolitical tensions, war, terrorism, natural disasters, public health issues, including pandemics such as COVID-19, industrial accidents and other business interruptions can harm or disrupt international commerce and the global economy, and could have a material adverse effect on the Company and its customers, suppliers, outsource partners, logistics providers, distributors, cellular network carriers and other channel partners. Weak or unstable economic conditions generally, inflation and actions taken by central banks to counter inflation (such as those that prevailed in recent years), sustained uncertainty about global political conditions, periods of intense diplomatic or armed conflict, government spending cuts and the impact of new government policies (including the introduction of new or increased taxes, the imposition of minimum taxes or new or increased limitations on deductions, credits or other tax benefits, or any other changes to tax laws), or a tightening of credit markets, including as a result of rising interest rates or bank failures, could cause our customers and potential customers to postpone or reduce spending on technology products or services or put downward pressure on prices, which could have an adverse effect on our business, results of operations or cash flows. Decreases or delays in spending on technology products and services by our customers due to, among other things, customer spending decisions and government spending and funding policies may have an adverse impact on our business. Our sales are impacted by customer decisions on budget priorities and technology spending, including decisions to defer any such spending. Our customer's spending decisions and budget priorities have and can be impacted by government spending and funding policies, especially but not exclusively for our public sector, healthcare and education customers, and our other customers that do business with our public sector customers or otherwise rely directly or indirectly on government funding. Federal government spending policies and budget priorities often shift during a change in federal administration, which has and can create increased levels of uncertainty with respect to these policies and priorities. An adverse change or anticipated change in government spending or funding policies (such as budget cuts or limitations), shifts in budget priorities, reductions in revenue levels or significant government shutdowns could cause our customers to reduce or delay their purchases or to terminate or not renew their contracts with us, which could adversely affect our business, results of operations or cash flows. Additionally, such adverse change in government spending policies, shifts in budget priorities or reductions in revenue levels could impact cash collections from contracts which could adversely affect our business, results of operations or cash flows.

The interruption of the flow of products from suppliers could disrupt our supply chain. Our business depends on the timely supply of products in order to meet the demands of our customers. Manufacturing interruptions or delays, including as a result of the financial instability or bankruptcy of manufacturers, significant labor disputes such as strikes, natural disasters (which may increase in number or severity as a result of climate change), political or social unrest, armed conflict, pandemics (such as the COVID-19 pandemic) or other public health crises, or other adverse occurrences affecting any of our suppliers' facilities, could disrupt our supply chain and cause volatility in our level of inventory and delays in completion of orders and installations for our customers. We have experienced and could in the future experience product constraints due to the failure of suppliers to accurately forecast customer demand, or to manufacture sufficient quantities of product to meet customer demand (including as a result of shortages of product components), among 16 other reasons. Additionally, the relocation of key distributors utilized in our purchasing model could increase our need for, and the cost of, working capital and have an adverse effect on our business, results of operations or cash flows. Moreover, supply chain disruptions have caused and could in the future cause us to experience more volatility in our level of inventory and delays in completion of orders and installations for our customers and could exacerbate inflationary pressures, such as those that prevailed in recent years. Supply chain pressures have and could in the future cause us to experience changes in average selling prices and our gross margins on certain products as customers have become and could in the future become more price sensitive. Our supply chain is also exposed to risks related to international operations. While we purchase our products primarily in the markets we serve (for example, products for US customers are sourced in the US), our vendor partners manufacture or purchase a significant portion of the products we sell outside of the US, primarily in Asia. Political, social or economic instability in Asia, or in other regions in which our vendor partners purchase or manufacture the products we sell, could cause disruptions in trade, including exports to the US. Other events related to international operations that could cause disruptions to our supply chain include: •the imposition of additional trade law provisions or regulations, including the adoption or expansion of trade restrictions; •the imposition of additional duties, tariffs and other charges on imports and exports, including any resulting retaliatory tariffs or charges and any reductions in the production of products subject to such tariffs and charges;

We are party to various legal proceedings that arise in the ordinary course of our business, which include commercial, employment, tort and other litigation. We are also subject to intellectual property infringement claims against us in the ordinary course of our business, either because of the products and services we sell or the business systems and processes we use to sell such products and services, in the form of cease-and-desist letters, licensing inquiries, lawsuits and other communications and demands. In our industry, such intellectual property claims have become more frequent as the complexity of technological products and the intensity of competition in our industry have increased. Increasingly, many of these assertions are brought by non-practicing entities whose principal business model is to secure patent licensing revenue, but we may also be subject to demands from inventors, competitors or other patent holders who may seek licensing revenue, lost profits and/or an injunction preventing us from engaging in certain activities, including selling certain products or services. In addition, we are subject to proceedings, investigations and audits by federal, state, international, national, provincial and local authorities, including as a result of our significant sales to governmental entities. For example, the Company received a Civil Investigative Demand, issued by the US Department of Justice ("DOJ") on June 11, 2024, in connection with a False Claims Act investigation. The DOJ requested information relating to bids the Company submitted for contracts funded in whole or in part by the Schools and Libraries Program (E-Rate Program). We also are subject to audits by various partners, group purchasing organizations and customers, including government agencies, relating to purchases and sales under various contracts. In addition, we are subject to indemnification claims under various contracts. Current and future litigation, infringement claims, governmental proceedings and investigations, audits or indemnification claims that we face may result in substantial costs and expenses and significantly divert the attention of our management regardless of the outcome. In addition, these matters could lead to increased costs or interruptions of our normal business operations. Litigation, infringement claims, governmental proceedings and investigations, audits or indemnification claims involve uncertainties and the eventual outcome of any such matter could adversely affect our business, results of operations or cash flows. Failure to comply with complex and evolving laws and regulations applicable to our operations or failure to meet stakeholder expectations on environmental sustainability and corporate responsibility matters could adversely affect our business, results of operations or cash flows. Our global operations span a variety of legal regimes, subjecting us to numerous complex, diverse, evolving and at times potentially inconsistent or conflicting laws and regulations in a number of areas, including labor and employment, advertising, e-commerce, tax, trade, import and export controls, economic and trade sanctions, anti-corruption, data privacy and security requirements, competition, environmental, social and governance and health and safety. The evaluation of and compliance with these laws, regulations and similar requirements, including evolving laws and regulations and regulatory overhaul during any change in federal administration, may be onerous and expensive, and may have other adverse impacts on our business, results of operations or cash flows, the risk of which will be heightened as we expand the products and services we offer, expand into new markets and channels and expand internationally. For example, we may be subject to increased costs and use of operational resources associated with complying with a myriad of new environmental, social and governance related laws and regulations. We have implemented policies and procedures designed to help ensure compliance with applicable laws and regulations, but there can be no guarantee against coworkers, contractors or agents violating such laws and regulations or our policies and procedures. Additionally, there is increased focus by stakeholders on environmental sustainability and corporate responsibility matters, and stakeholders may disagree with the Company's commitments and initiatives on such matters. Our disclosure on these matters and our failure, or perceived failure, to meet our commitments (including with respect to climate change) or otherwise effectively address these matters may erode customer trust or confidence, particularly if such failures or perceived failures receive considerable publicity or result in litigation, and could have a negative impact on our business. As a public company, we also are subject to increasingly complex public disclosure, corporate governance and accounting requirements that increase compliance costs and require significant management focus. 18

Risks Related to Our Indebtedness Our level of indebtedness could adversely affect our business. As of December 31, 2024, we had $5.8 billion of total debt outstanding and $355 million of obligations outstanding under our inventory financing agreements, and the ability to borrow an additional $1.2 billion under our senior unsecured revolving loan facility (the "Revolving Loan Facility"). Our level of indebtedness could have important consequences, including the following: •making it more difficult for us to satisfy our obligations with respect to our indebtedness; •requiring us to dedicate a substantial portion of our cash flow from operations to debt service payments on our and our subsidiaries' debt, which reduces the funds available for working capital, capital expenditures, acquisitions and other general corporate purposes; •requiring us to comply with restrictive covenants in our senior credit facilities and indentures, which limit the manner in which we conduct our business; •making it more difficult for us to obtain financing from our vendor partners, including original equipment manufacturers, software publishers and cloud providers, and our wholesale distributors; •limiting our flexibility in planning for, or reacting to, changes in the industry in which we operate; •placing us at a competitive disadvantage compared to any of our less-leveraged competitors;

Substantial competition could reduce our market share and significantly harm our financial performance. We compete with resellers, manufacturers who sell directly to customers, large service providers and system integrators, communications service providers, cloud providers, e-commerce companies and office supply retailers, among others. We expect the competitive landscape to continue to evolve as new technologies and consumption models emerge, such as cloud-based and other "as a service" solutions, hyper-converged infrastructure, embedded software solutions and solutions that incorporate artificial intelligence. Our continued competitiveness depends upon our ability to anticipate and evolve at pace and scale with new technologies, services and solutions through strategic and timely investments in innovation, expansion of offerings and the capabilities necessary to implement them. While innovation can help our business as it creates new offerings for us to sell, it can also disrupt our business model and create new and stronger competitors. For instance, while cloud-based solutions present an opportunity for us, cloud-based solutions and technology solutions as a service could increase the amount of sales directly to customers rather than through solutions providers like us, or could reduce the amount of hardware we sell. In addition, some of our hardware and software vendor partners sell, and could intensify their efforts to sell, their products directly to our customers. Moreover, traditional OEMs have increased their services capabilities through mergers and acquisitions, which could potentially increase competition in the market to provide comprehensive technology solutions to customers. If we are unable to effectively respond to the evolving competitive landscape, or respond in a manner that is less effective than that of our competitors, our business, results of operations or cash flows could be adversely impacted. We focus on providing high quality service to gain new customers and retain existing customers. To the extent we face increased competition to gain and retain customers, we may be required to reduce prices, increase advertising expenditures or take other actions which could adversely affect our business, results of operations or cash flows. Additionally, some of our competitors may reduce their prices in an attempt to stimulate sales, which may require us to reduce prices. This would require us to sell a greater number of products to achieve the same level of Net sales and Gross profit. If such a reduction in prices occurs and we are unable to attract new customers and sell increased quantities of products, our sales growth and profitability could be adversely affected. 11

•could elect to declare all borrowings outstanding thereunder, together with accrued and unpaid interest and fees, to be due and payable; or •could require us to apply all of our available cash to repay these borrowings.

indebtedness. Even if we were able to obtain new financing, it may not be on commercially reasonable terms, or terms that are acceptable to us. Failure to maintain the ratings assigned to our debt securities by rating agencies may increase our future borrowing costs and reduce our access to capital. Major debt rating agencies regularly evaluate our debt based on a number of factors, and any rating assigned could be lowered or withdrawn by a rating agency if, in that rating agency's judgment, future circumstances relating to the basis of the rating, such as adverse changes in our financial position, so warrant. We may not be able to maintain our existing investment grade ratings from certain credit rating agencies, and the failure to do so could increase the cost of servicing certain of our existing indebtedness and make it more difficult to raise debt financing on favorable terms in the future. We and our subsidiaries may be able to incur substantially more debt, including secured debt. This could further increase the risks associated with our leverage. We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of our senior credit facilities and indentures do not fully prohibit us or our subsidiaries from doing so. To the extent that we incur additional indebtedness, the risks associated with our level of indebtedness described above, including our possible inability to service our debt, could increase. As of December 31, 2024, we had $1.2 billion available for additional borrowing under our Revolving Loan Facility.

Variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly. Certain of our borrowings, primarily borrowings under our senior credit facilities, are at variable rates of interest and expose us to interest rate risk. As of December 31, 2024, we had $635 million of variable rate debt outstanding. When interest rates increase, our debt service obligations on the variable rate indebtedness increase even though the amount borrowed remains the same, and could negatively impact our net income absent any derivative instruments. From time to time, we may execute derivative instruments to reduce interest rate volatility, subject to acceptable terms. We cannot assure you we will enter into such derivative instruments in the future or that such instruments will be effective.

A natural disaster or other adverse occurrence at one of our primary facilities or a third-party provider location could damage our business. If the warehouse and distribution equipment or operations at one of our distribution centers or such facilities or operations of our outsource partners were to be seriously damaged or disrupted by a natural disaster, which may increase in number or severity as a result of climate change, or other adverse occurrence, including disruption related to political or social unrest, we could utilize another distribution center or third-party distributors to ship products to our customers. However, this may not be sufficient to avoid interruptions in our service and may not enable us to meet all of the needs of our customers and could cause us to incur incremental operating costs. In addition, we operate numerous facilities which may contain both business-critical data and confidential information of our customers and third parties, such as data center colocation, managed services sites and hosted solution partners, and third parties provide services as a component of our services delivery to customers. A natural disaster or other adverse occurrence at any of our major data storage locations, managed services sites or third-party provider locations could negatively impact our business, results of operations or cash flows. 14

We are exposed to accounts receivable and inventory risks. We extend credit to our customers for a significant portion of our sales. We are subject to the risk that our customers may not pay for the products they have purchased or may pay at a slower rate than we have historically experienced. These risks are heightened during periods of global or industry-specific economic downturn or uncertainty, during periods of rising interest rates or, in the case of public sector customers, during periods of budget constraints or budget cuts. Further, evolving product delivery models, such as multi-year subscriptions, may result in prolonged risk as customer terms extend in duration. Significant failures of customers to timely pay all amounts due to us could adversely affect our business, results of operations or cash flows. We are also exposed to inventory risks as a result of the rapid technological changes that affect the market and pricing for the products we sell. In addition to drop-ship arrangements with many of our OEMs and wholesale distributors, we seek to minimize our inventory exposure through a variety of inventory management procedures and policies, including our rapid-turn inventory model, as well as vendor price protection and product return programs. However, if we were unable to maintain our rapid-turn inventory model, if there were unforeseen product developments that created more rapid obsolescence or if our vendor partners were to change their terms and conditions, our inventory risks could increase. We also from time to time take advantage of cost savings associated with certain opportunistic bulk inventory purchases offered by our vendor partners or we may decide to carry high inventory levels of certain products that have limited or no return privileges due to customer demand or request or to manage supply chain interruptions. If we purchase inventory in anticipation of customer demand that does not materialize, or if customers reduce, delay or decommit from orders, and if we were unable to return the inventory to a vendor partner, we would be exposed to an increased risk of inventory obsolescence.

●Solutions across IT lifecycle●Customer relationships driving insight into technology roadmaps Customers We provide integrated IT solutions to over 250,000 business, government, education and healthcare customers throughout the US, UK and Canada. We serve our customers through sales teams focused on customer end-markets that are supported by highly-skilled specialists and engineers. Our market segmentation allows us to customize our offerings and to provide enhanced expertise in designing and implementing IT solutions that meet our customer's specific needs. We have three reportable segments: Corporate, Small Business and Public. Our Corporate segment primarily serves US private sector business customers with more than 250 employees. Our Small Business segment primarily serves US private sector business customers with up to 250 employees. Our Public segment is comprised of government agencies and education and healthcare institutions in the US. We also have two other operating segments: CDW UK and CDW Canada, each of which do not meet the reportable segment quantitative thresholds and, accordingly, are included in an all other category ("Other"). In our US business, which represents approximately 90% of our Net sales, we currently have five dedicated customer channels: corporate, small business, government, education and healthcare, each of which generated $1.5 billion or greater in Net sales in 2024. Net sales to customers in the UK and Canada combined generated $2.5 billion in 2024. We believe this diversity of customer end-markets provides us with multiple avenues for growth and has been a key factor in our ability to weather economic and technology cycles and gain market share.

Partners We offer more than 100,000 products and services from more than 1,000 vendor partners, including well-established companies such as Adobe, APC, Apple, Amazon Web Services, Broadcom Inc., Cisco, Dell Technologies, Google, Hewlett Packard Enterprise, HP Inc., IBM, Intel, Lenovo, Microsoft, NetApp, Nutanix, Palo Alto Networks, Pure Storage and Samsung, as well as from emerging technology companies. This broad portfolio of vendor partners and technologies enables us to offer customers significant options and meet customer demand for the products and solutions that best meet their needs. We believe our value proposition to vendor partners enables us to evolve our offering as new technologies emerge and new companies seek us as a channel partner. In 2024, we generated $2.0 billion of Net sales from each of our three largest vendor partners. We have received the highest level of certification from major vendor partners such as Broadcom Inc., Cisco, Dell Technologies, Hewlett Packard Enterprise, IBM, Lenovo, Microsoft, NetApp, Nutanix, Palo Alto Networks and Samsung which reflects the extensive product and solution knowledge and capabilities that we bring to our customers. These certifications also provide us with access to favorable pricing, tools and resources, including vendor incentive programs, which we use to provide additional value to our customers. Our vendor partners also regularly recognize us with top awards and select us to develop and grow new customer solutions.

Inventory Management We operate two distribution centers in North America and one distribution center in the UK, which combined provide more than 1 million square feet in size. Leveraging our distribution and logistics capabilities, we handle and ship approximately 26 million units annually on an aggregate basis from our distribution centers. We also have drop-shipment arrangements with many of our OEMs and wholesale distributors, which permit us to offer products to our customers without having to take physical delivery at our distribution centers. These arrangements represented approximately 54% of total North America Net sales in 2024. We believe that the location of our distribution centers allows us to efficiently ship products to our customers and provide timely access to our principal distributors. We believe that our logistics and configuration capabilities delivered by our highly-skilled and certified team enable us to customize technology for our customers to meet their unique needs.

We believe competitive sources of supply are available in substantially all of the product categories that we offer. Competition The market for technology products, solutions and services is highly competitive and subject to economic conditions and rapid technological changes. This competitive environment includes the ability to tailor solutions to customer needs, the quality and breadth of product and service offerings, knowledge and expertise of sales force, customer service, price, product availability, speed of delivery and credit availability. We face competition from resellers, manufacturers who sell directly to customers, large service providers and system integrators, cloud providers, e-commerce companies, and office supply retailers, among others. Smaller, local or regional value-added resellers typically focus on a single solution suite or portfolio of solutions from one or two vendor partners. We believe we are well positioned to compete within this marketplace due to our competitive advantages. We expect the competitive landscape to continue to evolve as new technologies and consumption models emerge, such as cloud-based and other "as a service" solutions, hyper-converged infrastructure, embedded software solutions and solutions that incorporate artificial intelligence. While innovation can help our business as it creates new offerings for us to sell, it can also disrupt our business model and create new and stronger competitors. For additional information on the risks associated with competition, see "Item 1A. Risk Factors." We believe we have sustainable competitive advantages that differentiate us in the marketplace. We focus on providing high quality service to gain new customers and retain existing customers. We have built a strong sales organization and deep services and solutions capabilities over time and expect to continue to invest to enhance these capabilities. We believe the combination of our competitive advantages of scale, performance-driven culture and enhanced capabilities will help drive sustainable, profitable growth for us today and in the future. Our scale enables us to have a national and international footprint, as well as invest in resources to meet specific customer end-market needs. Our sellers are organized around unique customer end-markets that are both vertically and geographically focused. Our scale enables our ability to invest in specialists and engineers who work directly with our sellers to help customers implement complex IT solutions. We have cross-border relationships that enable us to serve the needs of our US, UK and Canadian-based customers in approximately 150 countries. Our strong, execution-oriented culture is underpinned by our compensation system.
