Pascal Desroches to Update Shareholders at Deutsche Bank Media, Internet & Telecom Conference on March 11

Non-GAAP Measures and Reconciliations to GAAP Measures Adjusted diluted EPS is calculated by excluding from operating revenues, operating expenses, other income (expenses) and income tax expense, certain significant items that are non-operational or non-recurring in nature, including dispositions and merger integration and transaction costs, actuarial gains and losses, significant abandonments and impairments, benefit-related gains and losses, employee separation and other material gains and losses. The tax impact of adjusting items is calculated using the effective tax rate during the quarter except for adjustments that, given their magnitude, can drive a change in the effective tax rate, in these cases, we use the actual tax expense or combined marginal rate of approximately 25%. The Company expects adjustments to 2025 reported diluted EPS to include an adjustment to remove equity in net income of DIRECTV, a non-cash mark-to-market benefit plan gain/loss, and other items. The adjustment to remove the equity in net income of DIRECTV is dependent upon cash distributions from DIRECTV and the timing of the closing of the sale of our DIRECTV investment, which is expected in mid-2025. The Company expects the mark-to-market adjustment, which is driven by interest rates and investment returns that are not reasonably estimable at this time, to be a significant item. Our projected first-quarter and full-year 2025 adjusted EPS depends on future levels of revenues and expenses, most of which are not reasonably estimable at this time. Accordingly, we cannot provide a reconciliation between this projected non-GAAP metric and the most comparable GAAP metric without unreasonable effort.

Free cash flow is defined as cash from operations minus cash flows related to our DIRECTV equity method investment (cash distributions less cash taxes paid from DIRECTV), minus capital expenditures and cash paid for vendor financing (classified as financing activities). First-quarter 2025 projected free cash flow of $2.8 billion, or higher, includes cash from operations of approximately $8.4 – $8.6 billion, minus approximately $1.4 – $1.5 billion of cash flows related to DIRECTV, which includes a special distribution of $1.138 billion, minus approximately $3.9 – $4.1 billion of capital expenditures and $0.2 billion of cash paid for vendor financing. Due to high variability and difficulty in predicting items that impact cash from operating activities, capital expenditures and vendor financing payments, the Company is not able to provide a reconciliation between full-year 2025 projected free cash flow and the most comparable GAAP metric without unreasonable effort.
