Use of Non-GAAP Financial Metrics and Additional Information Charter and Cox Agree to Transformative Combination 18 We use certain measures that are not defined by U.S. generally accepted accounting principles ("GAAP") to evaluate various aspects of our business. Adjusted EBITDA and free cash flow are non-GAAP financial measures and should be considered in addition to, not as a substitute for, net income attributable to Charter shareholders and net cash flows from operating activities reported in accordance with GAAP. These terms, as defined by us, may not be comparable to similarly titled measures used by other companies. Adjusted EBITDA and free cash flow are reconciled to net income attributable to Charter shareholders and net cash flows from operating activities, respectively, in the financial addendum of our April 25, 2025 Form 8-K (Quarterly Earnings Release). Adjusted EBITDA is defined as net income attributable to Charter shareholders plus net income attributable to noncontrolling interest, net interest expense, income taxes, depreciation and amortization, stock compensation expense, other income (expenses), net and other operating (income) expenses, net, such as special charges and (gain) loss on sale or retirement of assets. As such, it eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of our businesses as well as other non-cash or special items, and is unaffected by our capital structure or investment activities. However, this measure is limited in that it does not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues and our cash cost of financing. These costs are evaluated through other financial measures. Free cash flow is defined as net cash flows from operating activities, less capital expenditures and changes in accrued expenses related to capital expenditures. Management and Charter's board of directors use Adjusted EBITDA and free cash flow to assess Charter's performance and its ability to service its debt, fund operations and make additional investments with internally generated funds. In addition, Adjusted EBITDA generally correlates to the leverage ratio calculation under our credit facilities or outstanding notes to determine compliance with the covenants contained in the facilities and notes (all such documents have been previously filed with the Securities and Exchange Commission (the "SEC")). For the purpose of calculating compliance with leverage covenants, we use Adjusted EBITDA, as presented, excluding certain expenses paid by our operating subsidiaries to other Charter entities. Our debt covenants refer to these expenses as management fees, which were $366 million and $371 million for the three months ended March 31, 2025 and 2024, respectively. For a reconciliation of Adjusted EBITDA and free cash flow to the most directly comparable GAAP financial measure, refer to the financial addendum of our April 25, 2025 Form 8-K (Quarterly Earnings Release). Pro forma Adjusted EBITDA is Cox Communications adjusted EBITDA, as adjusted to reflect the elimination of expenses related to items not included in the transaction and certain management adjustments, and is reconciled to Cox Communications net income on slide 19. Customer relationships include the number of customers that receive one or more levels of service, encompassing Internet, video, mobile and voice services, without regard to which service(s) such customers receive. Customers who reside in residential multiple dwelling units ("MDUs") and that are billed under bulk contracts are counted based on the number of billed units within each bulk MDU. Total customer relationships exclude mid-market and large business relationships and mobile-only customer relationships. All company data based on respective company reporting methodologies, where there may be definitional differences.
