Caution Concerning Forward-looking Statements This presentation includes statements that may constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934. 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," "goal," "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 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 changes in and/or risks associated with: the competitive environment; consumer behavior; the advertising market; programming costs; consumer acceptance of our content; key distribution and/or licensing agreements; use and protection of our intellectual property; our reliance on third-party hardware, software and operational support; keeping pace with technological developments; cyber attacks, security breaches or technology disruptions; weak economic conditions; acquisitions and strategic initiatives; operating businesses internationally; natural disasters, severe weather-related and other uncontrollable events; loss of key personnel; laws and regulations; adverse decisions in litigation or governmental investigations; labor disputes; and 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 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. Non-GAAP Financial Measures This presentation also includes certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted EPS and Free Cash Flow. Refer to the Notes following this presentation for a description of our non-GAAP measures and we also provide reconciliations to the most directly comparable GAAP financial measures in our Form 8-K (Quarterly Earnings Release) announcing our quarterly earnings and in our trending schedule, which can be found on the SEC's website at www.sec.gov and on our website at www.cmcsa.com. 2 COMCAST
