Item 8.01 Other Events

On October 9, 2025, Comcast Corporation ("Comcast" or the "Company") completed (i) the previously announced private offers (the "Exchange Offers") to exchange its 4.150% Notes due 2028 and 4.550% Notes due 2029 (collectively, the "Pool 2 Notes") for up to $1,000,000,000 in aggregate principal amount of the Company's new Notes due 2037 (the "New Notes") and (ii) the previously announced offers to purchase for cash all validly tendered and not validly withdrawn Pool 2 Notes (the "Cash Offers").

On October 9, 2025, Comcast completed the Exchange Offers and the Cash Offers. Pursuant to the Exchange Offers, the Company issued $480,046,000 in aggregate principal amount of the New Notes. The New Notes will bear interest at a rate of 5.168% per year and will mature on January 15, 2037. We will pay interest on the New Notes on January 15 and July 15 of each year, beginning on January 15, 2026.

The New Notes were issued pursuant to an Indenture dated as of September 18, 2013 (the "Base Indenture") among Comcast, the guarantors named therein and The Bank of New York Mellon, as trustee (the "Trustee"), as supplemented by the First Supplemental Indenture dated as of November 17, 2015 (the "First Supplemental

Indenture") among Comcast, the guarantors named therein and the Trustee and as further supplemented by the Second Supplemental Indenture dated as of July 29, 2022 (the "Second Supplemental Indenture") among Comcast, the guarantors named therein and the Trustee, and an officers' certificate issued pursuant thereto. The New Notes are guaranteed on an unsecured and unsubordinated basis by Comcast Cable Communications, LLC and NBCUniversal (the "Guarantors").

The material terms and conditions of the New Notes are set forth (i) in the Form of Officers' Certificate filed herewith as Exhibit 4.1, (ii) in the Base Indenture, filed as Exhibit 4.3 to Comcast's Registration Statement on Form S-3, as amended, filed on September 18, 2013 (Reg. No 333-191239), (iii) in the First Supplemental Indenture, filed as Exhibit 4.4 to Comcast's Post Effective Amendment No. 2 to Registration Statement on Form S-3, filed on November 23, 2015 (Reg. No 333-191239) and (iv) in the Second Supplemental Indenture, filed as Exhibit 4.4 to Comcast's Registration Statement on Form S-3, filed on July 29, 2022 (Reg. No. 333-266390), each of which are incorporated by reference herein.

In connection with Comcast's issuance of the New Notes, Comcast and the Guarantors entered into a registration rights agreement (the "Registration Rights Agreement") with the joint lead dealer managers for the Exchange Offers, on behalf of themselves and each co-dealer manager for the Exchange Offers. Under the Registration Rights Agreement, the Company and the Guarantors agreed, among other things, to use commercially reasonable efforts to file a registration statement with the Securities and Exchange Commission with respect to a registered offer to exchange the New Notes for a series of exchange notes with terms substantially identical in all material respects to the New Notes, except that the exchange notes will not contain transfer restrictions and will not provide for any increase in annual interest rate.

The New Notes have not been registered under the U.S. Securities Act of 1933, as amended (the "Securities Act") or any other applicable securities laws. Therefore, the New Notes may not be offered or sold except pursuant to an exemption from or in a transaction not subject to the registration requirements of the Securities Act and the applicable state securities laws.
