Comcast Results Presentation Deck

NOTES Numerical information is presented on a rounded basis using actual amounts. Minor differences in totals and percentage calculations may exist due to rounding. Beginning in the first quarter of 2023, we changed our presentation of segment operating results around our two primary businesses, Connectivity & Platforms and Content & Experiences. We have updated certain historical information as a result of these changes, including: (1) presentation of Cable Communications results in the Residential Connectivity & Platforms and Business Services Connectivity segments and (2) presentation of Sky's results across the Connectivity & Platforms and Content & Experiences segments, and Corporate & Other. Customer metrics for 2022 have been updated to reflect the new segment presentation, and to align methodologies for counting business customer metrics to: (1) include locations receiving our services outside of our distribution system and (2) now count certain customers based on the number of locations receiving services, including arrangements whereby third parties provide connectivity services leveraging our distribution system. These changes in methodology were not material to any period presented. We define Adjusted EBITDA as net income attributable to Comcast Corporation before net income (loss) attributable to noncontrolling interests, income tax expense, investment and other income (loss), net, interest expense, depreciation and amortization expense, and other operating gains and losses (such as impairment charges related to fixed and intangible assets and gains or losses on the sale of long-lived assets), if any. From time to time, we may exclude from Adjusted EBITDA the impact of certain events, gains, losses or other charges (such as significant legal settlements) that affect the period-to-period comparability of our operating performance. Refer to our Form 8-K (Quarterly Earnings Release) for a reconciliation and further details. We define Adjusted EPS as our diluted earnings per common share attributable to Comcast Corporation shareholders adjusted to exclude the effects of the amortization of acquisition-related intangible assets, investments that investors may want to evaluate separately (such as based on fair value) and the impact of certain events, gains, losses or other charges that affect period-over-period comparisons. Refer to our Form 8-K (Quarterly Earnings Release) for a reconciliation and further details. We define Free Cash Flow as net cash provided by operating activities (as stated in our consolidated Statement of Cash Flows) reduced by capital expenditures and cash paid for intangible assets. From time to time, we may exclude from Free Cash Flow the impact of certain cash receipts or payments (such as significant legal settlements) that affect period-to-period comparability. Cash payments related to certain capital or intangible assets, such as the construction of Universal Beijing Resort, are presented separately in our Statement of Cash Flows and are therefore excluded from capital expenditures and cash paid for intangible assets for Free Cash Flow. Refer to our Form 8-K (Quarterly Earnings Release) for a reconciliation and further details. Constant currency growth rates are calculated by comparing the results for each comparable prior year period adjusted to reflect the average exchange rates from each current period presented, rather than the actual exchange rates that were in effect during the respective periods. Refer to our Form 8-K (Quarterly Earnings Release) for a reconciliation and further details. From time to time, we may present adjusted information (e.g., Adjusted Revenues) to exclude the impact of certain events, gains, losses or other charges affecting period-to-period comparability of our operating performance. Reported 4Q23 and 4Q22 Consolidated, Connectivity & Platforms, Residential Connectivity & Platforms, Business Services Connectivity and Content & Experiences Adjusted EBITDA included severance and other in those periods. Refer to our Form 8-K (Quarterly Earnings Release) for a reconciliation and further details. As of December 31, 2023 - Consolidated net debt of $87.6 billion represents long-term debt, including current portion (as stated in our Consolidated Balance Sheet), less cash and cash equivalents (as stated in our Consolidated Balance Sheet) and adjusted to exclude $3.5 billion of debt and $0.3 billion of cash at Universal Beijing Resort. Consolidated net leverage is calculated as net debt/trailing twelve month Adjusted EBITDA, adjusted to exclude Universal Beijing Resort. The denominator of $37.4 billion represents Adjusted EBITDA for the twelve months ended December 31, 2023 of $37.6 billion, as presented in our trending schedule, adjusted to exclude $0.2 billion of Universal Beijing Resort Adjusted EBITDA. As of December 31, 2022 - Consolidated net debt of $86.7 billion represents long-term debt, including current portion (as stated in our Consolidated Balance Sheet), less cash and cash equivalents (as stated in our Consolidated Balance Sheet) and adjusted to exclude $3.5 billion of debt and $0.1 billion of cash at Universal Beijing Resort. Consolidated net leverage is calculated as net debt/trailing twelve month Adjusted EBITDA, adjusted to exclude Universal Beijing Resort. The denominator of $36.6 billion represents Adjusted EBITDA for the twelve months ended December 31, 2022 of $36.5 billion, as presented in our trending schedule, adjusted to exclude $0.2 billion of Universal Beijing Resort Adjusted EBITDA losses. 11
