Forward- looking statements are not historical facts or statements of current conditions, but instead represent only our beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside of our control. These may include estimates, projections and statements relating to our business plans, objectives and expected operating results, which are based on current expectations and assumptions that are subject to risks and uncertainties that may cause actual results to differ materially. These forward-looking statements are generally identified by the words "believe," "project," "expect," "anticipate," "estimate," "intend," "potential," "strategy," "future," "opportunity," "commit," "plan," "may," "should," "could," "will," "would," "will be," "will continue," "will likely result" and similar expressions. In evaluating these statements, you should consider various factors, including the risks and uncertainties we describe in the "Risk Factors" sections of our most recent Annual Report on Form 10-K, our most recent Quarterly Report on Form 10-Q and in other reports we file with the Securities and Exchange Commission. Factors that could cause our actual results to differ materially from these forward-looking statements include: (1) impacts from the COVID-19 pandemic, (2) changes in the competitive environment, (3) changes in business and economic conditions, (4) changes in our programming costs, (5) changes in laws and regulations, (6) changes in technology, (7) loss of key vendors, (8) adverse decisions in litigation matters, (9) risks associated with acquisitions and strategic initiatives, including Peacock, (10) changes in assumptions underlying our critical accounting judgments and estimates, and (11) other risks described from time to time in reports and other documents we file with the Securities and Exchange Commission. You are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date they are made. We undertake no obligation to update or revise publicly any forward-looking statements, whether because of new information, future events or otherwise. The amount and timing of any dividends and share repurchases are subject to business, economic and other relevant factors.

Minor differences in totals and percentage calculations may exist due to rounding. Beginning in the first quarter of 2021, we changed the presentation of segment operating results relating to NBCUniversal. The operations of Peacock, which were previously reported in Corporate and Other, are now included in NBCUniversal results, and the operations of NBCUniversal are now presented in three reportable business segments: Media, Studios and Theme Parks. Prior periods have been revised for these and certain other changes. Refer to our Form 8-K (Quarterly Earnings Release) for further details. We define Adjusted EBITDA as net income attributable to Comcast Corporation before net income (loss) attributable to noncontrolling interests and redeemable subsidiary preferred stock, 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. 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 results in 3Q20 and 3Q21 include the impacts of Cable Communications RSN related adjustments and the Tokyo Olympics in the Media segment, respectively. Refer to our Form 8-K (Quarterly Earnings Release) for a reconciliation and further details. We define Cable Communications Net Cash Flow as Cable Communications Adjusted EBITDA reduced by capital expenditures and cash paid for capitalized software and other intangible assets. Refer to our trending schedules for a reconciliation and further details. Sky constant currency growth rates are calculated by comparing the current period results to the comparative prior year period results adjusted to reflect the average exchange rates from the current year period rather than the actual exchange rates in effect during the respective prior year periods. Refer to our Form 8-K (Quarterly Earnings Release) for a reconciliation and further details. As of September 30, 2021 - Consolidated net debt of $82.3 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 $3.4 billion of debt and $0.3 billion of cash at Universal Beijing Resort. Amounts owed under a collateralized obligation are presented separately in our Consolidated Balance Sheet and are therefore excluded from consolidated net debt. Consolidated net leverage is calculated as net debt/trailing twelve month Adjusted EBITDA, adjusted to exclude Universal Beijing Resort. The denominator of $33.9 billion represents Adjusted EBITDA for the twelve months ended September 30, 2021 of $33.5 billion, as presented in our trending schedules, adjusted to exclude $0.5 billion of Universal Beijing Resort Adjusted EBITDA losses. As of September 30, 2020 - Consolidated net debt of $89.3 billion represents long-term debt, including current portion (as stated in our Consolidated Balance Sheet), adjusted to exclude $2.1 billion of Universal Beijing Resort debt, plus $725 million of NBCUniversal Enterprise, Inc. preferred stock, less cash and cash equivalents (as stated in our Consolidated Balance Sheet). Amounts owed under a collateralized obligation are presented separately in our Consolidated Balance Sheet and are therefore excluded from consolidated net debt. Consolidated net debt/Adjusted EBITDA is calculated based on trailing twelve month Adjusted EBITDA. Adjusted EBITDA for the twelve months ended September 30, 2020 was $32.1 billion, as presented in our trending schedules. 11#12COMCAST
