Non-GAAP Financial Information

This presentation contains certain Non-GAAP financial measures, including Non-GAAP operating income, Non-GAAP operating income margin and Non-GAAP net income. Generally, a Non-GAAP financial measure is a numerical measure of a company's performance or financial condition that either excludes or includes amounts that are not normally included or excluded in the most directly comparable measure calculated and presented in accordance with US GAAP. For a reconciliation of Non-GAAP financial measures to the applicable most comparable US GAAP financial measures, see Exhibit 99.1 to CDW's Current Report on Form 8-K filed with the SEC on August 2, 2023 and the reconciliations included in these slides. Non- GAAP financial measures used by CDW may differ from similar measures used by other companies, even when similar terms are used to identify such measures.
