Conflict Minerals Report

For the Year Ended December 31, 2024

Introduction

This Conflict Minerals Report (this "Report") of Comcast Corporation ( "Comcast", the "Company," "we," "us," or "our") for calendar year 2024 has been prepared in accordance with Rule 13p-1 under the Securities Exchange Act of 1934 ("Rule 13p-1"), as modified by guidance of the U.S. Securities and Exchange Commission ("SEC") (the "Conflict Minerals Rule").

The Conflict Minerals Rule requires issuers to annually file a Form SD with the SEC to disclose information regarding the use and origin of "Conflict Minerals" necessary for the functionality or production of products manufactured or contracted to be manufactured by such issuer. Under the Conflict Minerals Rule, "Conflict Minerals" currently include columbite-tantalite (coltan), cassiterite, gold, wolframite, and also their derivatives, tantalum, tin and tungsten. We refer to gold, tantalum, tin and tungsten collectively as "3TG." The purpose of the Conflict Minerals Rule is to discover if issuers' use of 3TG may have directly or indirectly financed or benefited armed groups in the Democratic Republic of Congo and its adjoining countries (the "Covered Countries").

This Report describes the Company's compliance program for products covered by the Conflict Minerals Rule, as well as steps taken to implement the compliance program, conduct in good faith an investigation as to the country of origin of the minerals used in the products that are within the scope of the Conflict Minerals Rule and perform due diligence on the source and chain of custody of such minerals (see "Product Description and Determination" below).

This Report is based on information available at the time of filing. This Report may contain forward-looking statements regarding steps to be taken in the future, and those statements are subject to risks and uncertainties.
