Network and information systems and other technologies, including those that are related to our network management, customer service operations and programming delivery and are embedded in our products and services, are critical to our business activities. In the ordinary course of our business, there are constant attempts by unauthorized parties to cause systems-related events and security incidents and to identify and exploit vulnerabilities in security architecture and system design. These incidents include computer hacking, cyber attacks, computer viruses, worms or other destructive or disruptive software, denial of service attacks, phishing attacks, malware, ransomware, malicious social engineering, theft, misconduct, fraud and other malicious activities. Incidents can be caused inadvertently by us or our third-party vendors, such as process breakdowns, human error, software or hardware failures or vulnerabilities in security architecture or system design. Cyber threats and attacks are constantly evolving and are growing in sophistication and frequency, which increases the difficulty of detecting and successfully defending against them. For example, we expect threat actors will continue to gain sophistication by using tools and techniques, such as AI, that are specifically designed to circumvent security controls. Some cyber attacks have had, and in the future can have, cascading impacts that unfold with increasing speed across networks, information systems and other technologies across the world and create latent vulnerabilities in our and third-party vendors’ systems and other technologies. We also obtain certain confidential, proprietary and personal information about our customers, personnel and vendors, that in many cases is provided or made available to third-party vendors who agree to protect it, which has in the past, and may in the future, become compromised through a cyber attack or data breach, misappropriation, misuse, leakage, falsification or accidental release or loss of information by us or a third party. Due to the nature of our businesses, we may be at a disproportionately heightened risk of these types of incidents occurring because we maintain certain information necessary to conduct our business in digital form. We also incorporate third-party software (including extensive open-source software), applications, and data hosting and cloud-based services into many aspects of our products, services and operations, as well as rely on service providers to help us perform our business operations, all of which expose us to cyber attacks with respect to such third-party suppliers and service providers and their products and services. Due to applicable laws, regulations and contractual obligations, we may be held responsible for cybersecurity breaches or incidents experienced by such third parties in relation to the information we share with them. Due to the complexity and interconnectedness of our systems and those of our third-party vendors, the process of enhancing our protective measures can itself create a risk of systems disruptions and security issues. While we develop and maintain systems, and operate programs that seek to prevent security incidents from occurring, these efforts are costly and must be constantly monitored and updated in the face of sophisticated and rapidly evolving attempts to overcome our security measures and protections. The occurrence of both intentional and unintentional incidents has caused, and may from time to time in the future cause, a variety of business impacts. These include degradation or disruption of our network, products and services, excessive call volume to call centers, theft or misuse of our intellectual property or other assets, disruption of the security of our internal systems, products, services or satellite transmission signals, power outages, and the compromise or exfiltration of sensitive, personal, proprietary, confidential or technical business information and customer or vendor data, and reputational impacts. In addition, despite efforts to detect unlawful intrusions, attacks can persist for an extended period of time before being detected, and following detection, it may take considerable time to understand the nature, scope, impact and timing of the incident. Moreover, the amount and scope of insurance we maintain against losses resulting from any of the foregoing events likely would not be sufficient to fully cover our losses or otherwise adequately compensate us for disruptions to our business that may result. Repercussions of these incidents, some of which we have experienced in the past, could include litigation or cause regulators to impose significant fines or other remedial measures, including with respect to relevant customer privacy rules, or otherwise have an adverse effect on our company. Despite our efforts, we expect that we will continue to experience such incidents in the future, and there can be no assurance that any such incident will not have an adverse effect on our business, reputation or results of operations.

We compete for the sale of advertising time with digital properties, including an increasing number of ad-supported DTC streaming service providers as advertisers have shifted, and may continue to shift, a larger portion of their total expenditures to digital media. We also compete with other online content providers, such as social networking platforms and user-generated content providers, television networks and stations, and all other advertising platforms. Because we derive substantial revenue from the sale of advertising, a decline in expenditures by advertisers, including through traditional linear television distribution models or on Peacock, could negatively impact our results of operations. We have experienced, and may continue to experience, declines caused by the economic prospects of specific advertisers or industries and economic conditions generally; increased competition for the leisure time of viewers, audience fragmentation and viewing content on DTC streaming services; use of time-shifting or advertising-blocking technologies; and regulatory intervention on advertising placement. Lower audience ratings and reduced viewership, which many of our linear television networks have experienced, and likely will continue to experience, as well as the level of popularity of Peacock, affect advertisers’ willingness to purchase advertising from us and the rates paid. Advertising sales and rates also are dependent on the methodology used for audience measurement and could be negatively affected if methodologies do not accurately reflect actual viewership levels.

We compete for the sale of advertising time with television networks and stations, digital properties, including an increasing number of ad-supported DTC streaming service providers and a broad array of other online content providers, such as social networking platforms and user-generated content providers, and all other advertising platforms. We derive substantial revenue from the sale of advertising, and we expect that a decline in expenditures by advertisers, including through traditional linear television distribution models or on Peacock, could negatively impact our results of operations. We have experienced, and may continue to experience, declines caused by the economic prospects of specific advertisers or industries, increased competition for the leisure time of viewers, such as from social networking and user-generated content platforms and video games, audience fragmentation, increased viewing of content through DTC streaming and other OTT service providers, increased use of time-shifting and advertising-blocking technologies or regulatory intervention regarding where and when advertising may be placed, and economic conditions generally. In addition, advertisers have shifted, and may continue to shift, a portion of their total expenditures to digital media, including DTC streaming service providers and other online content providers, and this trend may continue or accelerate. Lower audience ratings and reduced viewership, which many of our linear television networks have experienced, and likely will continue to experience, as well as the level of popularity of Peacock, affect advertisers’ willingness to purchase advertising from us and the rates paid.

We rely on our intellectual property, such as patents, copyrights, trademarks and trade secrets, as well as licenses and other agreements with our vendors and other third parties, to use various technologies, conduct our business operations and sell our products and services. Legal challenges to our intellectual property rights and claims of intellectual property infringement, misappropriation or other violation by third parties could require that we enter into royalty or licensing agreements on unfavorable terms, incur substantial monetary liability, or be enjoined preliminarily or permanently from further use of the intellectual property in question, from importing into the United States or other jurisdictions in which we operate hardware or software that uses such intellectual property or from the continuation of our businesses as currently conducted. We may need to change our business practices if any of these events occur, which may limit our ability to compete effectively and could have an adverse effect on our results of operations. Even if we believe any such challenges or claims are without merit, they can be time-consuming, costly to defend and may divert management’s attention and resources away from our businesses. Moreover, if we are unable to obtain, or continue to obtain, licenses from our vendors and other third parties on reasonable terms, or at all, our businesses could be adversely affected.

The unauthorized reproduction, distribution or display of copyrighted material negatively affects our ability to generate revenue from the legitimate sale of our content, as well as from the sale of advertising in connection with our content, and increases our costs due to our active enforcement of our intellectual property rights. The legal landscape for new technologies, including AI, remains uncertain, and legal developments could impact our ability to protect against unauthorized third-party use, misappropriation, reproduction or infringement or impact our ability to deploy new technologies. Our use or adoption of new and emerging technologies may also increase our exposure to intellectual property claims. Piracy and other unauthorized uses of content are made easier, and the enforcement of intellectual property rights more challenging, by technological advances that allow the conversion of programming, films and other content into digital formats, which facilitates the creation, transmission and sharing of high-quality unauthorized copies. In particular, piracy of programming and films through unauthorized distribution platforms continues to present challenges for our businesses. For example, certain entities may stream our broadcast television content illegally online without our consent and without paying us any compensation, and sporting events on our international networks may be illegally transmitted. While piracy is a challenge in the United States, it is particularly prevalent in many parts of the world that lack developed copyright laws, effective enforcement of copyright laws and technical protective measures like those in effect in the United States. If any U.S. or international laws intended to combat piracy and protect intellectual property rights are repealed or weakened or are not adequately enforced, or if the legal system fails to adapt to new technologies that facilitate piracy, we may be unable to effectively protect our rights, the value of our intellectual property may be negatively impacted and our costs of enforcing our rights may increase.

A substantial portion of our revenue comes from customers whose spending patterns may be affected by prevailing economic conditions. Weak economic conditions in the United States, in Europe or globally could adversely affect demand for any of our products and services and have a negative impact on our results of operations. For example, weak economic conditions will likely impact our customers’ discretionary spending and as a result, they may reduce the level of services to which they subscribe or may discontinue subscribing to one or more of our services altogether. This risk may be increased by the expanded availability of free or lower cost competitive services, such as certain DTC streaming services, or substitute services for broadband and voice services, such as wireless and public Wi-Fi networks. Weak economic conditions also negatively impact our advertising revenue, the performance of our films and home entertainment releases, and attendance and spending in our theme parks. In particular, the success of our theme parks and theatrical releases largely depends on consumer demand for out-of-home entertainment experiences, which may be limited by weakened economic conditions. Weak economic conditions may also cause governments and regulators to impose additional tax or product affordability regulations, which could have a negative impact on our results of operations. Weak economic conditions and disruptions in the global financial markets, such as high interest rates, may impact our ability to obtain financing or to refinance existing debt on acceptable terms, if at all, which could increase the cost of our borrowings over time and may increase our exposure to currency fluctuations in countries where we operate. Further, inflationary pressures in the United States, in Europe and globally may also have negative impacts on our cost structure and pricing models and may impact the ability of third parties (including advertisers, customers, suppliers, wholesale distributors, retailers and content creators, among others) to satisfy their obligations to us.

Our services, products and properties are vulnerable to damage from the occurrence of certain events, including natural disasters, severe weather events such as hurricanes and wildfires, and a range of other unforeseeable events such as infectious disease outbreaks, terrorist attacks or other similar events. Such events have in the past caused, and could in the future cause, a variety of adverse business impacts including degradation or disruption of our network, products and services, excessive call volume to call centers, a reduction in demand for our products, services and theme parks, disruption of our internal systems, products, services or satellite transmission signals, power outages, and damage to our or our customers’ or vendors’ equipment and properties. These events also may result in lost revenue and large expenditures to repair or replace damaged properties, products and services and could lead to litigation and regulatory fines or remedial measures, including if we inadvertently contributed to damages suffered by others. The amount and scope of insurance we maintain against losses resulting from these types of events likely would not be sufficient to fully cover our losses or otherwise adequately compensate us for disruptions to our business that may result. We expect that we will continue to experience some or all of these events in the future, and there can be no assurance that any such event will not have an adverse effect on our business, reputation or results of operations.

Our success is, to a large extent, dependent on our ability to acquire, develop, adopt and leverage new and existing technologies, and our competitors’ use of certain types of technology, including AI, and equipment may provide them with a competitive advantage. New technologies can materially impact our businesses in a number of ways, including affecting the demand for our products, the distribution methods of our products and content to our customers, how we create our entertainment products, the ways in which our customers can purchase and view our content and the growth of distribution platforms available to advertisers. For example, current and new wireless internet technologies (including 5G fixed wireless networks and 4G and 5G wireless broadband services) continue to evolve rapidly and may allow for greater speed and reliability for those services as compared with prior technologies and create further competition for our businesses. In addition, some companies and U.S. municipalities are building advanced fiber-based networks that provide very fast internet access speeds, and some providers offer newer satellite broadband services. We expect advances in communications technology to continue to occur in the future. If we choose technology or equipment that is not as effective or attractive to consumers as that employed by our competitors, if we fail to employ technologies desired by consumers or that enhance our business operations, such as through the use of AI, or if we fail to execute effectively on our technology initiatives, our businesses and results of operations could be adversely affected. We also will continue to incur additional costs as we execute our technology initiatives, such as the deployment of multigigabit symmetrical speeds by leveraging our DOCSIS 4.0 technology and the development and enhancement of various streaming platforms. There can be no assurance that we can execute on these and other initiatives in a manner sufficient to grow or maintain our revenue or to successfully compete in the future. We also may generate less revenue or incur increased costs if changes in our competitors’ product offerings require that we offer certain services or enhancements at a lower or no cost to our customers or that we increase our research and development expenditures. 21Comcast 2024 Annual Report on Form 10-K 21Comcast 2024 Annual Report on Form 10-K 21Comcast 2024 Annual Report on Form 10-K 21 Comcast 2024 Annual Report on Form 10-K 21Comcast 2024 Annual Report on Form 10-K 21Comcast 2024 Annual Report on Form 10-K 21 Comcast 2024 Annual Report on Form 10-K 21Comcast 2024 Annual Report on Form 10-K 21 Comcast 2024 Annual Report on Form 10-K 21 Comcast 2024 Annual Report on Form 10-K Table of Contents Table of Contents Table of Contents

Our success is, to a large extent, dependent on our ability to acquire, develop, adopt and leverage new and existing technologies, and our competitors’ use of certain types of technology and equipment may provide them with a competitive advantage. New technologies can materially impact our businesses in a number of ways, including affecting the demand for our products, the distribution methods of our products and content to our customers, how we create our entertainment products, the ways in which our customers can purchase and view our content and the growth of distribution platforms available to advertisers. For example, current and new wireless internet technologies (including 5G fixed wireless networks and 4G and 5G wireless broadband services) continue to evolve rapidly and may allow for greater speed and reliability for those services as compared with prior technologies and create more competitors for our businesses. In addition, some companies and U.S. municipalities are building advanced fiber-based networks that provide very fast internet access speeds, and some providers offer newer satellite broadband services.

We continue to focus on growing our higher-margin connectivity businesses while managing overall operating costs. We also continue to invest in our network to support higher-speed broadband offerings and to expand the number of homes and businesses passed. A competitive environment, which has increased in recent years, has had negative impacts on our customer relationships additions/(losses). In addition, government funding for the Affordable Connectivity Program, which provided a monthly discount towards broadband service for eligible low-income households, expired during the second quarter of 2024, which had a negative impact on our residential domestic broadband customer relationships. We believe our residential connectivity revenue will increase as a result of growth in average domestic broadband revenue per customer, as well as increases in domestic wireless and international connectivity revenue. At the same time, we expect continued declines in video revenue as a result of domestic customer net losses due to shifting video consumption patterns and the competitive environment, although customer net losses typically mitigate the impact of continued rate increases on programming expenses. We also expect continued declines in other revenue related to declines in wireline voice revenue. We believe our Business Services Connectivity segment will continue to grow by offering competitive services, including enterprise solutions. 35Comcast 2024 Annual Report on Form 10-K 35Comcast 2024 Annual Report on Form 10-K 35Comcast 2024 Annual Report on Form 10-K 35 Comcast 2024 Annual Report on Form 10-K 35Comcast 2024 Annual Report on Form 10-K 35Comcast 2024 Annual Report on Form 10-K 35 Comcast 2024 Annual Report on Form 10-K 35Comcast 2024 Annual Report on Form 10-K 35 Comcast 2024 Annual Report on Form 10-K 35 Comcast 2024 Annual Report on Form 10-K Table of Contents Table of Contents Table of Contents Connectivity & Platforms Customer Metrics Net Additions / (Losses)(in thousands)2024202320242023Customer RelationshipsDomestic Residential Connectivity & Platforms customer relationships(a)31,172 31,648 (476)(212)International Residential Connectivity & Platforms customer relationships(a)17,81117,847(36)(93)Business Services Connectivity customer relationships(b)2,6262,641(16)17 Total Connectivity & Platforms customer relationships51,60952,136(527)(288)Domestic BroadbandResidential customers29,37329,748(375)(64)Business customers2,4692,505(36)(2)Total domestic broadband customers31,84232,253(411)(66)Domestic WirelessTotal domestic wireless lines(c)7,8266,5881,237 1,275 Domestic VideoTotal domestic video customers12,52314,106(1,583)(2,037)Domestic homes and businesses passed(d)63,69262,457Domestic broadband penetration of homes and businesses passed(e)49.8 %51.5 % Domestic Residential Connectivity & Platforms customer relationships(a) International Residential Connectivity & Platforms customer relationships(a) Business Services Connectivity customer relationships(b) Total domestic wireless lines(c) Domestic homes and businesses passed(d) Domestic broadband penetration of homes and businesses passed(e) Domestic Residential Connectivity & Platforms customer relationships(a) International Residential Connectivity & Platforms customer relationships(a) Business Services Connectivity customer relationships(b) Total domestic wireless lines(c) Domestic homes and businesses passed(d) Domestic broadband penetration of homes and businesses passed(e) (a)Residential Connectivity & Platforms customer relationships generally represent the number of residential customer locations that subscribe to at least one of our services.

Our businesses are subject to various federal, state, local and federal laws and regulations. In the United States in particular, the Communications Act and FCC rules and regulations affect significant aspects of our communications businesses. Legislators and regulators at all levels of government frequently consider changing, and sometimes do change, existing statutes, rules or regulations, or interpretations of existing statutes, rules or regulations, or prescribe new ones, any of which may significantly affect our businesses and ability to effectively compete. Applying existing laws in novel ways to new technologies, including streaming services and AI, may also affect our business. These legislators and regulators, along with some state attorneys general and foreign governmental authorities, have been active in conducting inquiries and reviews regarding our services. State legislative and regulatory initiatives can create a patchwork of different and/or conflicting state requirements, such as with respect to privacy and Open Internet/net neutrality regulations, that can affect our businesses and ability to effectively compete.

For example, Congress has approved tens of billions of dollars in new funding for broadband deployment and adoption initiatives, and may from time to time consider other proposals that address communications issues, including whether it should rewrite the Communications Act to account for changes in the communications marketplace. Federal agencies have considered adopting new regulations for communications services, including broadband, although it is uncertain whether those initiatives will continue under the new Administration. States and localities are increasingly proposing new regulations impacting communications services, including broader regulation of broadband networks. Regulators in various international jurisdictions are similarly considering changes to telecommunications and media requirements. Any of these regulations could significantly affect our business and our legal and compliance costs. In addition, United States and foreign regulators and courts could adopt new interpretations of existing competition or antitrust laws or enact new competition or antitrust laws or regulatory tools that could negatively impact our businesses. Any future legislative, judicial, regulatory or administrative actions may increase our costs or impose additional restrictions on our businesses, some of which may be significant. We are unable to predict the outcome or effects of any of these potential actions or any other legislative or regulatory proposals on our businesses. Failure to comply with the laws and regulations applicable to our businesses could result in administrative enforcement actions, fines, and civil and criminal liability. Any changes to the legal and regulatory framework applicable to any of our services or businesses could have an adverse impact on our businesses and results of operations.

State legislative and regulatory initiatives can create a patchwork of different and/or conflicting state requirements, such as with respect to privacy and Open Internet/net neutrality regulations, that can affect our businesses and ability to effectively compete. Legislative and regulatory activity has increased under the Biden Administration, particularly with respect to broadband networks. For example, Congress has approved tens of billions of dollars in new funding for broadband deployment and adoption initiatives, and may consider other proposals that address communications issues, including whether it should rewrite the entire Communications Act to account for changes in the communications marketplace and whether it should enact new, permanent Open Internet/net neutrality requirements.

For example, the FCC has proposed reimposing network neutrality requirements that would reclassify our broadband service as a “telecommunications service” under Title II of the Communications Act, which would authorize the FCC to potentially regulate our customer rates, speeds, data usage thresholds or other terms for internet services and prohibit, or seriously restrict, arrangements between us and internet content, applications and service providers.

We operate our businesses worldwide. There are risks inherent in doing business internationally, including global financial market turmoil; economic volatility and global economic slowdown; currency exchange rate fluctuations and inflationary pressures; geopolitical risks, including acts of terror and war; requirements of local laws and customs relating to the publication and distribution of content and the display and sale of advertising; import or export restrictions, tariffs, sanctions and trade regulations; difficulties in developing, staffing and managing foreign operations; issues related to occupational safety and adherence to diverse local labor laws and regulations; and potentially adverse tax developments. Additionally, although we employ foreign currency derivative instruments to hedge certain exposure to foreign currency exchange rate risks, including the British pound, euro and Japanese yen, the use of such derivative instruments may not be sufficient to mitigate exchange rate fluctuations. In addition, doing business internationally subjects us to risks relating to political or social unrest, as well as corruption and government regulations, including U.S. laws such as the Foreign Corrupt Practices Act and the U.K. Bribery Act, that impose stringent requirements on how we conduct our foreign operations. Moreover, foreign enforcement of laws and contractual rights in certain countries where we do business can be inconsistent and unpredictable, which may affect our ability to enforce our rights or make investments that we believe otherwise make strategic sense. If any of these events occur or our conduct does not comply with such laws and regulations, our businesses may be adversely affected. 23Comcast 2024 Annual Report on Form 10-K 23Comcast 2024 Annual Report on Form 10-K 23Comcast 2024 Annual Report on Form 10-K 23 Comcast 2024 Annual Report on Form 10-K 23Comcast 2024 Annual Report on Form 10-K 23Comcast 2024 Annual Report on Form 10-K 23 Comcast 2024 Annual Report on Form 10-K 23Comcast 2024 Annual Report on Form 10-K 23 Comcast 2024 Annual Report on Form 10-K 23 Comcast 2024 Annual Report on Form 10-K Table of Contents Table of Contents Table of Contents

We operate our businesses worldwide. There are risks inherent in doing business internationally, including global financial market turmoil; economic volatility and global economic slowdown; currency exchange rate fluctuations and inflationary pressures; geopolitical risks, including acts of terror and war; requirements of local laws and customs relating to the publication and distribution of content and the display and sale of advertising; import or export restrictions, tariffs, sanctions and trade regulations; difficulties in developing, staffing and managing foreign operations; issues related to occupational safety and adherence to diverse local labor laws and regulations; and potentially adverse tax developments. Additionally, although we employ foreign currency derivative instruments to hedge certain exposure to foreign currency exchange rate risks, including the British pound, euro and Japanese yen, the use of such derivative instruments may not be sufficient to mitigate exchange rate fluctuations. In addition, doing business internationally subjects us to risks relating to political or social unrest, as well as corruption and government regulations, including U.S. laws such as the Foreign Corrupt Practices Act and the U.K. Bribery Act, that impose stringent requirements on how we conduct our foreign operations. Moreover, foreign enforcement of laws and contractual rights in certain countries where we do business can be inconsistent and unpredictable, which may affect our ability to enforce our rights or make investments that we believe otherwise make strategic sense. If any of these events occur or our conduct does not comply with such laws and regulations, our businesses may be adversely affected.

We create and acquire media, sports and entertainment content, the success of which depends substantially on consumer tastes and preferences that often change in unpredictable ways. To meet the changing preferences of our consumer markets, we must consistently create, acquire, market and distribute a broad array of content and theme park attractions. We have invested, and will continue to invest, substantial amounts in content, such as the production of films and original content for television networks and streaming services, and in the creation of new theme parks and theme park attractions, before learning the extent to which they will earn consumer acceptance. We obtain a significant portion of our content from third parties, such as movie studios, television production companies, sports organizations and other suppliers, sometimes on an exclusive basis. Competition for popular content, particularly for sports programming, is intense. Entering into or renewing contracts for such content rights or acquiring additional rights has in the past resulted, and may result in the future, in significantly increased costs, potentially over an extended contractual term. Particularly with respect to contracts for sports rights, our results of operations and cash flows over the term of a contract depend on a number of factors, including the strength of the advertising market, audience size, the timing and amount of rights payments, and the ability to secure distribution from, impose surcharges on, or obtain carriage on multichannel video providers or to grow and retain subscribers to our own DTC services. There can be no assurance that revenue generated from these contracts will exceed our costs for the rights and of producing and distributing the programming. In addition, media companies may determine not to license popular content to us, and as more content owners offer their content directly to consumers through their own platforms, they may reduce the quantity and quality of the content they license to our linear television networks or Peacock. The inability to enter into or renew some or all of these contracts on acceptable terms could reduce the reach of our programming, which could adversely affect our results of operations and businesses. 19Comcast 2024 Annual Report on Form 10-K 19Comcast 2024 Annual Report on Form 10-K 19Comcast 2024 Annual Report on Form 10-K 19 Comcast 2024 Annual Report on Form 10-K 19Comcast 2024 Annual Report on Form 10-K 19Comcast 2024 Annual Report on Form 10-K 19 Comcast 2024 Annual Report on Form 10-K 19Comcast 2024 Annual Report on Form 10-K 19 Comcast 2024 Annual Report on Form 10-K 19 Comcast 2024 Annual Report on Form 10-K Table of Contents Table of Contents Table of Contents We also create content for licensing to third parties and to our linear television networks or Peacock. The inability to license such content on acceptable terms or at all could negatively impact our business. Moreover, we may generate lower revenue when we opt to retain our content for our own use, including for Peacock, rather than licensing it to third parties who pay licensing fees for such content. If our content does not achieve sufficient consumer acceptance, or if we cannot obtain or retain rights to popular content on acceptable terms, or at all, our businesses may be adversely affected.

We create and acquire media and entertainment content, the success of which depends substantially on consumer tastes and preferences that often change in unpredictable ways, and to meet the changing preferences of the broad domestic and international consumer markets, we must consistently create, acquire, market and distribute television programming, filmed entertainment, theme park attractions and other content. We have invested, and will continue to invest, substantial amounts in content, such as the production of films and original content for television networks and streaming services, and in the creation of new theme parks and theme park attractions, before learning the extent to which they will earn consumer acceptance. In addition, there can be no assurance that Peacock will continue to grow or sustain its revenue or user base, successfully compete as a standalone DTC streaming service or fully offset decreases to our linear television networks’ results of operations as the media distribution business model continues to change. We obtain a significant portion of our content from third parties, such as movie studios, television production companies, sports organizations and other suppliers, sometimes on an exclusive basis. Competition for popular content, particularly for sports programming, is intense, and at times, we may increase the price we are willing to pay or be outbid by our competitors for popular content. We also may be unable to license popular third-party content if media companies determine that licensing the content to us is not in their strategic best interests. For example, content creators have launched, and may continue to launch, their own DTC streaming or other OTT services, forgoing license fees from us to provide their content directly to consumers, or they may license their content to our competitors on an exclusive basis. 21Comcast 2023 Annual Report on Form 10-K 21Comcast 2023 Annual Report on Form 10-K 21Comcast 2023 Annual Report on Form 10-K 21 21Comcast 2023 Annual Report on Form 10-K 21Comcast 2023 Annual Report on Form 10-K 21 21Comcast 2023 Annual Report on Form 10-K 21 21 Table of Contents Table of Contents Table of Contents Entering into or renewing contracts for such content rights or acquiring additional rights has in the past resulted, and may result in the future, in significantly increased costs.

(a)Constant currency is a non-GAAP financial measure. Refer to the “Non-GAAP Financial Measure” section on page 44 for additional information, including our definition and our use of constant currency, and for a reconciliation of constant currency amounts. Average monthly total revenue per customer relationship is impacted by rate adjustments and changes in the types and levels of services received by our residential and business customers, as well as changes in advertising and other revenue and in foreign currency exchange rates. While revenue from our individual service offerings is also impacted by changes in the allocation of revenue among services sold in a bundle, the allocation does not impact average monthly total revenue per customer relationship. Each of our services has a different contribution to Adjusted EBITDA margin. We use average monthly Adjusted EBITDA per customer relationship to evaluate the profitability of our customer base across our service offerings.

Constant Currency Change(a) (a)Constant currency is a non-GAAP financial measure. Refer to the “Non-GAAP Financial Measure’ section on page 47 for additional information, including our definition and our use of constant currency, and for a reconciliation of constant currency amounts. Average monthly total revenue per customer relationship is impacted by rate adjustments and changes in the types and levels of services received by our residential and business customers, as well as changes in advertising and other revenue and in foreign currency exchange rates. While revenue from our individual service offerings is also impacted by changes in the allocation of revenue among services sold in a bundle, the allocation does not impact average monthly total revenue per customer relationship. Each of our services has a different contribution to Adjusted EBITDA margin. We use average monthly Adjusted EBITDA per customer relationship to evaluate the profitability of our customer base across our service offerings. We believe both metrics are useful to understand the trends in our business, and average monthly Adjusted EBITDA per customer relationship is useful particularly as we continue to focus on growing our higher-margin businesses.

Distribution platforms for viewing and purchasing content continue to challenge existing business models, increase the number of competitors that our businesses face, and have driven, and will continue to drive, changes in consumer behavior as consumers seek control over when, where and how they consume content and access communications services, and how much or for how long they pay for such content.

The continuing trend of content owners, including us with Peacock, delivering their content directly to consumers, rather than through, or in addition to, traditional video distribution channels also disrupts traditional media distribution business models. As consumers increasingly turn to DTC streaming services in lieu of linear video services, which continue to experience accelerated net customer losses, our video customers and video revenues, and linear television network subscriber fees received from video service providers, each decrease. In addition to reducing traditional television viewership, these trends when coupled with time-shifting technologies, such as DVR and on demand services, have caused, and likely will continue to cause, audience ratings declines for our television networks. Shifting content consumption patterns also may result in lower demand for home entertainment products or theatrical attendance. While we have adapted some of our video and content offerings to compete in the evolving media distribution landscape, such as by offering Peacock and NOW, there also can be no assurance that we will be able to successfully compete or that Peacock will grow or sustain its revenue or user base, successfully compete as a stand-alone DTC streaming service or fully offset decreases to our linear television networks’ results of operations. Our failure to effectively anticipate or adapt to emerging competitors or changes in consumer behavior, including among younger consumers, and shifting business models could have an adverse effect on our competitive position, businesses and results of operations.

Distribution platforms for viewing and purchasing content have been, and will likely continue to be, developed that further challenge existing business models and increase the number of competitors that our businesses face. DTC streaming and other OTT services have driven, and will continue to drive, changes in consumer behavior as consumers seek more control over when, where and how they consume content and access communications services, and how much they pay for such content.

The continuing trend of content owners delivering their content directly to consumers, rather than through, or in addition to, traditional video distribution channels, continues to disrupt traditional media distribution business models despite our efforts to adapt our video service offerings and offer new services, such as Peacock and NOW. The number of entertainment choices available to consumers, such as DTC streaming and other OTT service providers and aggregators, social networking and user-generated content platforms, and gaming and virtual reality products and services, continue to significantly increase, intensify audience fragmentation and disaggregate the way that content traditionally has been distributed and viewed by consumers. This in turn has reduced traditional television viewership, and when coupled with time-shifting technologies, such as DVR and on demand services, has caused, and likely will continue to cause, audience ratings declines for our television networks. In addition, as more content owners offer their content directly to consumers through their own platforms, they may reduce the quantity and quality of the content they license to our linear television networks or Peacock. On the other hand, this practice may also negatively impact our results of operations when we keep our content for our own use, including for Peacock, rather than licensing it to third parties who pay us licensing fees for such content. Our failure to effectively anticipate or adapt to emerging competitors or changes in consumer behavior, including among younger consumers, and shifting business models could have an adverse effect on our competitive position, businesses and results of operations.

Our effective income tax rate in 2024 and 2023 was 15.0% and 26.2%, respectively. The decrease in income tax expense in 2024 was primarily driven by a tax benefit from an internal corporate reorganization completed in 2024, as well as lower domestic income before income taxes. See Note 5 for additional information on our income taxes.

Our effective income tax rate in 2023 and 2022 was 26.2% and 47.0%, respectively. Our effective income tax rate for 2022 was impacted by the goodwill impairment, which was primarily not deductible for tax purposes. See Note 5 for additional information on our effective income tax rate. The increase in income tax expense in 2023 was primarily driven by higher income before income taxes and the effect of a change in our net deferred tax liabilities as a result of the enactment of state tax law changes, which resulted in a $286 million benefit in the prior year.

The following graph illustrates the contributions to the change in consolidated costs and expenses, excluding depreciation expense and amortization expense, made by our Connectivity & Platforms and Content & Experiences businesses, as well as by Corporate and Other activities, including adjustments and eliminations. (a) Graph is presented using a truncated scale. Costs and expenses for our segments and our corporate operations and other businesses are discussed separately below under the heading “Segment Operating Results.” Consolidated depreciation and amortization expense increased in 2024 compared to 2023 primarily due to increased amortization of certain acquisition-related intangible assets related to the linear media business, partially offset by a decrease in depreciation of our international property and equipment and a decrease in the amortization of software. Amortization expense from acquisition-related intangible assets totaled $2.7 billion and $2.3 billion in 2024 and 2023, respectively. Amounts primarily relate to customer relationship intangible assets recorded in connection with the Sky transaction in 2018 and the NBCUniversal transaction in 2011. 33Comcast 2024 Annual Report on Form 10-K 33Comcast 2024 Annual Report on Form 10-K 33Comcast 2024 Annual Report on Form 10-K 33 Comcast 2024 Annual Report on Form 10-K 33Comcast 2024 Annual Report on Form 10-K 33Comcast 2024 Annual Report on Form 10-K 33 Comcast 2024 Annual Report on Form 10-K 33Comcast 2024 Annual Report on Form 10-K 33 Comcast 2024 Annual Report on Form 10-K 33 Comcast 2024 Annual Report on Form 10-K Table of Contents Table of Contents Table of Contents Consolidated interest expense increased in 2024 compared to 2023 primarily due to an increase in average debt outstanding and higher weighted-average interest rates in the current year, partially offset by interest expense in the prior year associated with a collateralized obligation that was repaid in the fourth quarter of 2023.

We operate our Media segment as a combined television and streaming business. We expect that the number of subscribers and audience ratings at our linear television networks will continue to decline as a result of the competitive environment and shifting video consumption patterns, which we aim to mitigate over time by continued growth in paid subscribers and advertising revenue at Peacock. We expect to continue to incur significant costs related to content and marketing at Peacock. Revenue and programming expenses are also impacted by the timing of certain sporting events, including the Olympics in the third quarter of 2024 and our acquisition of NBA rights, which begin in 2025. Our Studios segment generates revenue primarily from third parties and from licensing content to our Media segment. While results of operations for our Studios segment are not impacted, results for our total Content & Experiences business may be impacted as the Studios segment licenses content to the Media segment, including for Peacock, rather than licensing the content to third parties. The Writers Guild and the SAG work stoppages from May to September 2023 and July to November 2023, respectively, resulted in reduced content licensing revenue at our Studios segment and reduced programming and production costs at both our Studios and Media segments in 2023. We continue to invest significantly in existing and new theme park attractions, hotels and infrastructure, including Epic Universe in Orlando, which we expect will open in May 2025, as well as in new destinations and experiences, which we believe will have a positive impact on attendance and guest spending at our theme parks. 39Comcast 2024 Annual Report on Form 10-K 39Comcast 2024 Annual Report on Form 10-K 39Comcast 2024 Annual Report on Form 10-K 39 Comcast 2024 Annual Report on Form 10-K 39Comcast 2024 Annual Report on Form 10-K 39Comcast 2024 Annual Report on Form 10-K 39 Comcast 2024 Annual Report on Form 10-K 39Comcast 2024 Annual Report on Form 10-K 39 Comcast 2024 Annual Report on Form 10-K 39 Comcast 2024 Annual Report on Form 10-K Table of Contents Table of Contents Table of Contents
