The Exchange Offers are being conducted upon the terms and subject to the conditions set forth in an offering memorandum, dated August 2, 2021. Comcast reserves the right, in its sole and absolute discretion, to increase the 2051 Notes Cap, the 2056 Notes Cap and/or the 2063 Notes Cap without extending the Withdrawal Deadline (as defined below) or otherwise reinstating withdrawal rights.

Each Exchange Offer is subject to certain conditions, including, (i) with respect to the Pool 1 Offer, a minimum of $1,000,000,000 aggregate principal amount of New 2051 Notes being issued in the Pool 1 Offer, (ii) with respect to the Pool 2 Offer, a minimum of $1,000,000,000 aggregate principal amount of New 2056 Notes being issued in the Pool 2 Offer, (iii) with respect to the Pool 3 Offer, a minimum of $1,000,000,000 aggregate principal amount of New 2063 Notes being issued in the Pool 3 Offer, (iv) as of 10:00 a.m. New York City time on August 16, 2021, the combination of the yield of the New Notes and the total consideration or exchange consideration as described in the offering memorandum, as applicable, for the applicable series of Old Notes would result in the New Notes and such Old Notes not being treated as “substantially different” under ASC 470-50, (v) with respect to any Old Notes validly tendered pursuant to any Exchange Offer that will be exchanged on the Final Settlement Date (as defined below), we determine that the New Notes to be issued on the Final Settlement Date in such Exchange Offer will be treated as part of the same issue as the New Notes, if any, issued on the Early Settlement Date for U.S. federal income tax purposes pursuant to specified tests and (vi) if at 10:00 a.m. New York City time on August 16, 2021 the bid-side yield on the 2.375% U.S. Treasury Notes due May 15, 2051 (as used to determine the interest rates for the New Notes) is more than 2.250%, we will not be required to accept for exchange, or to issue New Notes of the applicable series in exchange for, the Old Notes of the applicable series and may terminate or amend the Exchange Offer with respect to such series.

Only Eligible Holders (as defined below) of Old Notes who validly tender their Old Notes at or before 5:00 p.m. New York City time on August 13, 2021, subject to any extension by Comcast (the “Early Participation Date”), who do not validly withdraw their tenders and whose Old Notes are accepted for exchange, will receive an early participation payment.

The Exchange Offers will expire at 11:59 p.m., New York City time, on August 27, 2021, unless extended or earlier terminated by Comcast (the “Expiration Date”). Tenders of Old Notes submitted in the Exchange Offers at or prior to 5:00 p.m. New York City time on August 13, 2021, subject to any extension by Comcast (the “Withdrawal Deadline”), may be validly withdrawn at any time prior to the Withdrawal Deadline, but thereafter will be irrevocable, except in certain limited circumstances where additional withdrawal rights are required by law (as determined by Comcast). Tenders submitted in the Exchange Offers after the Withdrawal Deadline will be irrevocable except in the limited circumstances where additional withdrawal rights are required by law (as determined by Comcast).

Comcast reserves the right, but is under no obligation, at any point following the Early Participation Date and before the Expiration Date, to accept for exchange any Old Notes validly tendered at or prior to the Early Participation Date (the date of such exchange, the “Early Settlement Date”). The Early Settlement Date will be determined at Comcast’s option and is currently expected to occur on August 19, 2021, the fourth business day immediately following the Early Participation Date. If, after the Early Participation Date, Comcast chooses to exercise its option to have an Early Settlement Date and all conditions to the relevant Exchange Offers have been or are concurrently satisfied or waived by Comcast, Comcast will, subject to the terms of the Exchange Offers, accept for exchange all Old Notes validly tendered in the Exchange Offers prior to the Early Participation Date subject to proration, and the exchange for such Old Notes will be made on the Early Settlement Date.

The Final Settlement Date for the Exchange Offers will be promptly after the Expiration Date and is currently expected to occur on August 31, 2021, the second business day immediately following the Expiration Date (the “Final Settlement Date”).
