(2) Accounts receivable, noncurrent are presented within Other assets on the Consolidated Balance Sheets. From time to time, the Company transfers certain accounts receivable, without recourse, to third-party financial companies as a method to reduce the Company’s credit exposure and accelerate cash collections. Such transfers are recognized as a sale and the related accounts receivable is derecognized from the Consolidated Balance Sheet upon receipt of payment from the third-party financing company. During the six months ended June 30, 2024 and 2023, the Company sold approximately $213 million and $219 million of accounts receivable, respectively. Contract Balances Contract assets and liabilities represent the difference in the timing of revenue recognition from receipt of cash from customers. Contract assets represent revenue recognized on performance obligations satisfied or partially satisfied for which the Company has no unconditional right to consideration. Contract liabilities consist of payments received from customers, or such consideration that is contractually due, in advance of providing the product or performing services. The following table details information about the Company’s contract balances recognized on the Consolidated Balance Sheets: June 30, 2024 December 31, 2023 Contract assets (1) $ 94.6 $ 111.8 Contract liabilities (2)(3) $ 484.7 $ 527.4 (1) Contract assets are presented within Prepaid expenses and other on the Consolidated Balance Sheets.

Inventory Financing Agreements

Inventory Financing Agreements [Abstract]
Inventory Financing Agreements	Inventory Financing Agreements The Company has entered into agreements with financial institutions to facilitate the purchase of inventory from designated suppliers under certain terms and conditions to enhance liquidity. Under these agreements, the Company receives extended payment terms and agrees to pay the financial institutions a stated amount of confirmed invoices from its designated suppliers. The Company does not incur any interest or other incremental expenses associated with these agreements as balances are paid when they are due. Additionally, the Company has no involvement in establishing the terms or conditions of the arrangements between its suppliers and the financial institutions. The amounts outstanding under these agreements as of June 30, 2024 and December 31, 2023 were $404 million and $431 million, respectively, and are separately presented as Accounts payable-inventory financing on the Consolidated Balance Sheets. The majority of such outstanding amounts relates to a floorplan sub-facility that is incorporated in the Company’s Revolving Loan Facility, as defined within Note 6 (Debt). A portion of the Company’s availability under the Revolving Loan Facility is reserved to cover the obligation to pay the financial institution. For additional information regarding the Revolving Loan Facility, see Note 6 (Debt).

Financial Instruments

Financial Instruments	6 Months Ended

Financial Instruments [Abstract]
Financial Instruments	Financial Instruments The Company does not hold or issue derivative financial instruments for trading or speculative purposes. The Company’s indebtedness creates interest rate risk on its variable-rate debt. The Company may use derivative financial instruments to manage its exposure to interest rate risk. For additional information, see Note 6 (Debt). The Company has interest rate collar agreements that provide for a contractually specified interest rate cap and an interest rate floor based on a Secured Overnight Financing Rate (“SOFR”). The Company receives payment from the counterparty if SOFR is greater than the cap or pays the counterparty if SOFR is below the floor. If SOFR is between the floor and cap, no payment is due to either party. There were no new interest rate collar agreements executed during the six months ended June 30, 2024. As of June 30, 2024 and December 31, 2023, the interest rate collar agreements were classified within Other assets and Long-term liabilities - Other liabilities, respectively, on the Consolidated Balance Sheets for which the fair value was not material. The total notional amount of the interest rate collar agreements was $400 million as of June 30, 2024 and December 31, 2023, and these agreements mature on September 30, 2026. The fair values of the Company’s interest rate collar agreements are classified as Level 2 in the fair value hierarchy. The valuation of the interest rate collar agreements is derived using a discounted cash flow analysis on the expected cash receipts or cash disbursements that would occur if variable interest rates rise above or fall below the strike rates of the interest rate cap and interest rate floor, respectively. This analysis reflects the contractual terms of the interest rate collar agreements, including the period to maturity, and uses observable market-based inputs, including SOFR curves and implied volatilities. The Company also incorporates insignificant credit valuation adjustments to appropriately reflect the respective counterparty’s nonperformance risk in the fair value measurements. The counterparty credit spreads are based on publicly available credit information obtained from a third-party credit data provider.

Credit Facility The Company has a variable rate senior unsecured revolving loan facility (the “Revolving Loan Facility”) from which it may draw tranches denominated in US dollars, British pounds or Euros. The interest rate is based on SOFR plus a spread adjustment and a margin based on the Company’s senior unsecured rating. The Revolving Loan Facility is used by the Company for borrowings, issuances of letters of credit and floorplan financing. As of June 30, 2024, the Company could have borrowed up to an additional $1.2 billion under the Revolving Loan Facility. As of June 30, 2024, the Revolving Loan Facility had $355 million reserved for the floorplan sub-facility. Term Loan The senior unsecured term loan facility (the “Term Loan Facility”) has a variable interest rate. The interest rate is based on SOFR plus a spread adjustment and a margin based on the Company’s senior unsecured rating. No mandatory payments are required on the remaining principal amount until its maturity date on December 1, 2026. Unsecured Senior Notes The unsecured senior notes have a fixed interest rate, which is paid semi-annually. Receivable Financing The receivable financing liability relates to certain accounts receivable transferred to third-party financial institutions that did not qualify as a sale under the terms of the agreements. While the terms of such agreements are on a nonrecourse basis, the transfers of accounts receivable could not achieve certain criteria that would allow derecognition of the accounts receivable. The proceeds from these arrangements are recognized as a liability and the associated accounts receivable remains on the Consolidated Balance Sheet until the liability is settled. The Company did not execute any transfers under these agreements during the six months ended June 30, 2024. Fair Value The fair values of the unsecured senior notes were estimated using quoted market prices for identical liabilities that are traded in over-the-counter secondary markets. The fair value of the Term Loan Facility was estimated using dealer quotes and other market observable inputs for comparable liabilities. The unsecured senior notes and Term Loan Facility were classified as Level 2 within the fair value hierarchy. The carrying value of the Revolving Loan Facility approximates fair value. The approximate fair values and related carrying values of the Company’s long-term debt, including current maturities and excluding unamortized discount and unamortized deferred financing costs, were as follows: June 30, 2024 December 31, 2023 Fair value $ 5,310.7 $ 5,348.2 Carrying value $ 5,652.7 $ 5,673.3

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The numerator for both basic and diluted earnings per share is Net income. The denominator for basic earnings per share is the weighted-average shares outstanding during the period. A reconciliation of basic weighted-average shares outstanding to diluted weighted-average shares outstanding is as follows: Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Basic weighted-average shares outstanding 134.1 134.6 134.3 135.1 Effect of dilutive securities (1) 1.5 1.5 1.5 1.6 Diluted weighted-average shares outstanding (2) 135.6 136.1 135.8 136.7 (1) The dilutive effect of outstanding stock options, restricted stock units, performance share units and Coworker Stock Purchase Plan units is reflected in the diluted weighted-average shares outstanding using the treasury stock method. (2) There were fewer than 0.3 million potential common shares excluded from diluted weighted-average shares outstanding for both the three and six months ended June 30, 2024 and 2023. Inclusion of these common shares in diluted weighted-average shares outstanding would have had an anti-dilutive effect.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is party to various legal proceedings that arise in the ordinary course of its business, which include commercial, intellectual property, employment, tort and other litigation matters. The Company is also subject to audit by federal, state, international, national, provincial and local authorities, and by various partners, group purchasing organizations and customers, including government agencies, relating to purchases and sales under various contracts. In addition, the Company is subject to indemnification claims under various contracts. From time to time, certain customers of the Company file voluntary petitions for reorganization or liquidation under the US bankruptcy laws or similar laws of the jurisdictions for the Company’s business activities outside of the US. In such cases, certain pre-petition payments received by the Company could be considered preference items and subject to return to the bankruptcy administrator. As of June 30, 2024, the Company does not believe that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these proceedings and matters, if any, has been incurred. However, the ultimate resolutions of these proceedings and matters are inherently unpredictable. As such, the Company’s Consolidated Financial Statements could be adversely affected in any particular period by the unfavorable resolution of one or more of these proceedings or matters. The Company received a Civil Investigative Demand, issued by the 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). The Company is cooperating with the DOJ and, at this stage of the investigation, is unable to assess the probability of any outcome or the range of possible loss, if any.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company’s segment information reflects the way the chief operating decision maker uses internal reporting to evaluate business performance, allocate resources and manage operations. The Company has three reportable segments: Corporate, which is primarily comprised of private sector business customers with more than 250 employees in the US, Small Business, which is primarily comprised of private sector business customers with up to 250 employees in the US, and Public, which is comprised of government agencies and education and healthcare institutions in the US. The Company has two other operating segments: CDW UK and CDW Canada, both of which do not meet the reportable segment quantitative thresholds and, accordingly, are included in an all other category (“Other”). The Company has centralized logistics and headquarters functions that provide services to the segments. The logistics function includes purchasing, distribution and fulfillment services to support the Corporate, Small Business and Public segments. As a result, costs and intercompany charges associated with the logistics function are fully allocated to all of these segments based on a percent of Net sales. The centralized headquarters function provides services in areas such as accounting, information technology, marketing, legal and coworker services. Headquarters function costs that are not allocated to the segments are included under the heading of “Headquarters” in the tables below. Information about the Company’s segments is as follows: Corporate Small Business Public Other Headquarters Total Three Months Ended June 30, 2024 Net sales $ 2,195.2 $ 382.9 $ 2,243.3 $ 602.0 $ — $ 5,423.4 Operating income (loss) 197.0 45.6 209.2 24.2 (42.9) 433.1 Depreciation and amortization expense (19.3) (0.8) (14.3) (7.1) (27.9) (69.4) Three Months Ended June 30, 2023 Net sales $ 2,245.0 $ 396.2 $ 2,295.1 $ 689.8 $ — $ 5,626.1 Operating income (loss) 206.5 42.4 210.3 32.4 (79.4) 412.2 Depreciation and amortization expense (19.6) (1.1) (14.2) (7.5) (23.5) (65.9) Six Months Ended June 30, 2024 Net sales $ 4,331.1 $ 763.8 $ 3,968.0 $ 1,233.2 $ — $ 10,296.1 Operating income (loss) 375.0 92.1 335.2 49.5 (90.7) 761.1 Depreciation and amortization expense (39.1) (1.8) (27.7) (14.2) (53.9) (136.7) Six Months Ended June 30, 2023 Net sales $ 4,448.7 $ 807.6 $ 4,107.9 $ 1,365.0 $ — $ 10,729.2 Operating income (loss) 399.8 83.9 337.8 68.9 (122.9) 767.5 Depreciation and amortization expense (42.4) (2.4) (30.4) (15.3) (46.1) (136.6) Geographic Areas and Revenue Mix Three Months Ended June 30, 2024 Corporate Small Business Public Other Total Geography (1) United States $ 2,182.7 $ 376.9 $ 2,242.0 $ 7.5 $ 4,809.1 Rest of World 12.5 6.0 1.3 594.5 614.3 Total Net sales $ 2,195.2 $ 382.9 $ 2,243.3 $ 602.0 $ 5,423.4 Major Product and Services Hardware $ 1,532.2 $ 307.3 $ 1,796.2 $ 426.2 $ 4,061.9 Software 416.2 53.5 288.7 97.2 855.6 Services 231.2 17.7 153.6 75.9 478.4 Other (2) 15.6 4.4 4.8 2.7 27.5 Total Net sales $ 2,195.2 $ 382.9 $ 2,243.3 $ 602.0 $ 5,423.4 Sales by Channel Corporate $ 2,195.2 $ — $ — $ — $ 2,195.2 Small Business — 382.9 — — 382.9 Government — — 639.1 — 639.1 Education — — 1,017.4 — 1,017.4 Healthcare — — 586.8 — 586.8 Other — — — 602.0 602.0 Total Net sales $ 2,195.2 $ 382.9 $ 2,243.3 $ 602.0 $ 5,423.4 Timing of Revenue Recognition Transferred at a point in time where CDW is principal $ 1,830.4 $ 337.2 $ 1,992.2 $ 512.0 $ 4,671.8 Transferred at a point in time where CDW is agent 193.2 34.2 134.5 30.8 392.7 Transferred over time where CDW is principal 171.6 11.5 116.6 59.2 358.9 Total Net sales $ 2,195.2 $ 382.9 $ 2,243.3 $ 602.0 $ 5,423.4 (1) Net sales by geography is generally based on the ship-to address with the exception of certain services that may be performed at, or on behalf of, multiple locations.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. The presentation of the Consolidated Financial Statements requires the Company to make estimates and assumptions that affect reported amounts and related disclosures. In the opinion of management, the Consolidated Financial Statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company’s financial position, results of operations, comprehensive income, cash flows and changes in stockholders’ equity as of the dates and for the periods indicated.
