PART I

Introduction

We are a leading broadband connectivity company with services available to 58 million homes and small to large businesses across 41 states through our Spectrum® brand. Founded in 1993, we have evolved from providing cable TV to streaming, and from high-speed Internet to a converged broadband, WiFi and mobile experience. Over the Spectrum Fiber Broadband Network and supported by our 100% U.S.-based employees, we offer Seamless Connectivity and Entertainment with Spectrum Internet®, Mobile, TV and Voice products.

Our strategy is focused on utilizing our fiber-powered network to deliver high-quality, competitively priced products, with outstanding service, allowing us to increase both the number of customers we serve over our network and the number of products we sell to each customer. This combination also reduces the number of service transactions we perform per relationship, yielding higher customer satisfaction and lower customer churn, which results in lower costs to acquire and serve customers and drives greater profitability.

Products

We offer Spectrum Internet products with speeds up to 1 gigabits per second (“Gbps”) across our entire footprint and multi-gigabit speeds in a portion of our footprint. We continue to upgrade our connectivity network, and we will offer symmetrical and multi-gigabit Internet speeds across our entire footprint in the next several years. Advanced WiFi, a managed WiFi service that provides customers an optimized home network while providing greater control of connected devices with enhanced security and privacy, is available to all of our Internet customers. Spectrum Mobile® is available to all new and existing Spectrum Internet customers and offers plans that include 5G access, do not require contracts and include taxes and fees in the price. We continue to innovate our video product and have transformed all of our affiliation agreements with major programmers. These new agreements give us greater overall packaging flexibility and the ability to include the ad-supported versions of key programmer streaming applications, at no extra cost, within our video packages, along with the ability to upgrade to ad-free versions and to sell those applications to customers a la carte for a seamless entertainment experience. Together with our Xumo Stream Boxes (“Xumo”), our goal is to deliver utility and value for our customers, irrespective of how they want to view content, and better and more stable economics for our programming partners and us.

Pricing & Packaging and Customer Commitments

Our fully deployed fiber-powered network offers ubiquitous and seamless connectivity products. It removes barriers and creates opportunities for customers, in every aspect of their lives. Our brand platform, Life Unlimited™, emphasizes the power of our advanced network and cutting-edge connectivity products and services, and our simplified pricing strategy better utilizes our seamless connectivity and entertainment products to offer lower promotional and persistent bundled pricing to drive growth. Additionally, our customer commitments focus on reliable connectivity, transparency, exceptional service and always improving. Through reliable connectivity, we are committed to keeping our customers connected 100% of the time and promptly resolving issues. Transparency at every step means we provide clear and simple pricing and timely service updates, and we take responsibility when things go wrong. Through exceptional service, we provide exceptional customer experiences. And finally, always improving means we act on our customers' feedback to improve our products and customer service.

Network Evolution

Our network and product evolution plan continues to progress, with a clear path to delivering symmetrical and multi-gig speeds to customers across our footprint, meeting the needs of today and anticipating the growing demand for faster speeds for years to come. We continue to expand the capacity of our fiber-powered network using a number of technologies, including

• spectrum expansion, initially to 1.2 GHz and then to 1.8 GHz;

• changing the bandwidth allocation to a "high split" to increase upstream speeds;

• Distributed Access Architecture ("DAA"); and

• DOCSIS 4.0 technology.

Through this process, which we expect to be largely complete by the end of 2027, we will transform our network to offer much faster Internet speeds. Those faster Internet speeds will be offered in conjunction with our Spectrum Mobile product and

Advanced WiFi, providing customers seamless and convenient, ultra-fast converged connectivity in attractively priced packages.

Expansion

Since inception in the beginning of 2022, we have spent $7.7 billion on our subsidized rural construction initiative and activated approximately 1.3 million passings. Rural footprint builds present strategic network expansion opportunities to deliver service to unserved and underserved passings. Our rural investments allow us to offer a suite of broadband connectivity services, including fixed Internet, WiFi and mobile to unserved areas in states where we currently operate. To accomplish all of this, we have invested in new construction teams and new equipment. These investments will allow us to generate long-term infrastructure-style returns by taking further advantage of our scale efficiencies, network quality and construction capabilities, while offering our high-quality products and services to more homes and businesses.

Our principal executive offices are located at 400 Washington Blvd., Stamford, Connecticut 06902. Our telephone number is (203) 905-7801, and we have a website accessible at ir.charter.com. Our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, and all amendments thereto, are available on our website free of charge as soon as reasonably practicable after they have been filed. The information posted on our website is not incorporated into this annual report.

Risks Related to Our Business

We operate in a very competitive business environment, which affects our ability to attract and retain customers and can adversely affect our business, operations and financial results.

The industry in which we operate is highly competitive and has become more so in recent years. In some instances, we compete against companies with fewer regulatory burdens, better access to financing and greater and more favorable brand name recognition. Increasing consolidation in the telecommunications and content industries have provided additional benefits to certain of our competitors, either through access to financing, resources, or efficiencies of scale including the ability to launch new products and services.

Our Internet service faces competition from other companies’ FTTH, cell phone home Internet service, Internet delivered via satellite and DSL services. Various operators offer wireless Internet services delivered over networks which they continue to enhance to deliver faster speeds and also continue to expand 5G mobile services as they seek to offer converged connectivity services similar to ours. Our mobile and voice services compete with wireless and wireline phone providers, as well as other forms of communication, such as text, instant messaging, social networking services, video conferencing and email. Competition from these companies, including intensive marketing efforts with aggressive pricing, may have an adverse impact on our ability to attract and retain customers.

Our video service faces competition from a number of sources, including DBS services, and companies that deliver linear network programming, movies and television shows on demand and other video content over broadband Internet connections to televisions, computers, tablets and mobile devices often with password sharing among multiple users and security that makes content susceptible to piracy. Newer products and services, particularly alternative methods for the distribution, sale and viewing of content may continue to be developed, further increasing the competition that we face.

The increasing number of choices available to audiences, including low-cost or free choices, could negatively impact not only consumer demand for our products and services, but also advertisers’ willingness to purchase advertising from us. We compete for the sale of advertising revenue with television networks and stations, as well as other advertising platforms, such as online media, radio and print. Competition related to our service offerings to businesses continues to increase as well, as more companies deploy more fiber to more buildings, which may negatively impact our growth and put pressure on margins.

A failure to effectively anticipate or adapt to new technologies (including those that use artificial intelligence (“AI”)) and changes in customer expectations and behavior could significantly adversely affect our competitive position with respect to the leisure time and discretionary spending of our customers and, as a result, affect our business and results of operations. Competition may also reduce our expected growth of future cash flows which may contribute to future impairments of our franchises and goodwill and our ability to meet cash flow requirements, including debt service requirements. For additional information regarding the competition we face, see “Item 1. Business - Competition” and “Item 1. Business - Regulation and Legislation.”

Various events could disrupt or result in unauthorized access to our networks, information systems or properties and could impair our operating activities and negatively impact our reputation and financial results.

Network and information systems technologies are critical to our operating activities, both for our internal uses, such as network management, and supplying services to our customers, including customer service operations and programming delivery. Network or information system shutdowns or other service disruptions caused by events such as computer hacking, phishing, dissemination of computer viruses, worms and other destructive or disruptive software, malicious cyber activities by nation-state threat actors, “cyber attacks” such as ransomware, process breakdowns, denial of service attacks and other malicious activity pose increasing risks. Both unsuccessful and successful “cyber attacks” on companies have continued to increase in frequency, scope and potential harm in recent years, and the increasing use of AI may intensify these cybersecurity risks. While we develop and maintain systems seeking to prevent systems-related events and security breaches from occurring, the development and maintenance of these systems is costly and requires ongoing monitoring and updating as techniques used in such attacks become more sophisticated and change frequently. We, and the third parties on which we rely, may be unable to anticipate these techniques or implement adequate preventive measures. While from time to time attempts have been made to access our network, these events have not as yet resulted in any material release of information, degradation or disruption to our network and information systems.

Our network and information systems are also vulnerable to damage or interruption from power outages, telecommunications failures, accidents, natural disasters (including extreme weather arising from short-term or long-term changes in weather patterns), terrorist attacks and similar events. Our system redundancy may be ineffective or inadequate, and our disaster recovery planning may not be sufficient for all eventualities.

We have experienced many of these events and may experience additional events in the future. Any of these events, if directed at, or experienced by, us or technologies upon which we depend, have had and could in the future have adverse consequences on our network, our customers and our business, including degradation of service, service disruption, excessive call volume to call centers, and damage to our or our customers’ equipment and data. Large expenditures and substantial resources have been and may in the future be necessary to repair or replace damaged property, networks or information systems or to protect them from similar events in the future. Moreover, the amount and scope of insurance that we maintain against losses resulting from any such events or security breaches has not always been and may not in the future be sufficient to cover our losses or otherwise adequately compensate us for any disruptions to our business that have resulted and may result. Any such significant service disruption could result in damage to our reputation and credibility, customer dissatisfaction and ultimately a loss of customers or revenue. Any significant loss of customers or revenue, or significant increase in costs of serving those customers, could adversely affect our growth, financial condition and results of operations.

Furthermore, our operating activities could be subject to risks caused by misappropriation, misuse, leakage, falsification or accidental release or loss of information maintained in our information technology systems and networks and those of our third-party vendors, including customer, personnel and vendor data. We provide certain confidential, proprietary and personal information to third parties in connection with our business, and there is a risk that this information may be compromised.

We process, store, and transmit large amounts of data, including the personal information of our customers. Ongoing increases in the potential for misuse of personal information, the public’s awareness of the importance of safeguarding personal information, and the volume of legislation that has been adopted or is being considered regarding the protection, privacy and security of personal information have resulted in increases to our information-related risks. We could be exposed to si

None.

Risk Management and Strategy

Cybersecurity risks are classified as a Tier 1 risk within our enterprise risk management program. We are committed to protecting the security and integrity of our systems, networks, databases and applications. We routinely invest to develop and implement numerous cybersecurity programs and processes, including risk management and assessment programs, security and event monitoring capabilities, detailed incident response plans, and other advanced detection, prevention and protection capabilities, including practices and tools to monitor and mitigate insider threats. We regularly assess cybersecurity risks to identify and enumerate threats to us and vulnerabilities these threats can exploit to adversely impact our business operations. Regular reviews of these risks and vulnerabilities drive our investment in new controls and technologies. In some instances, we engage third parties to conduct or assist us with conducting cybersecurity risk assessments.

Our cybersecurity program employs various risk-tracking tools, industry data, monitoring, detection and response tools, vulnerability scanning, security dashboards and scorecards and other tools to support our continued evaluation of cybersecurity threats and regulatory requirements. Our cybersecurity program addresses the continuously evolving and extensive attack vectors and methods through layered security controls informed by constant threat analysis. Threats include a wide variety of perpetrators aiming for political, personal or financial gain, utilizing a broad set of tactics including ransomware, advanced malware, DDoS, account takeover, phishing/SMSing, sabatoge and social engineering, among others. These risks threaten our internal systems as well as third-party systems that we use and rely upon for the delivery of services and support of our operations. Our risk mitigation techniques include least privileged access, network segmentation, deployment of enhanced detection tools across our network, systems, databases, and applications and monitoring compliance with security standards all based on a risk-based approach.

Various security standards provide guidance to telecommunications companies in order to help identify and mitigate cybersecurity risks, including the voluntary framework released by the National Institute for Standards and Technology (“NIST”) in 2014 and updated in 2018 and 2024, in cooperation with other federal agencies and owners and operators of U.S. critical infrastructure. The NIST cybersecurity framework provides a prioritized and flexible model for organizations to identify and manage cyber risks inherent to their business. Our security infrastructure is comprised of multiple security capabilities designed with a defense-in-depth model informed by the NIST cybersecurity framework, as well as a variety of other industry standards and best practices. The risk-based approach of the NIST cybersecurity framework has enabled us to implement cybersecurity programs tailored to our particular network architectures, customer environments and institutional resources.

As part of our cybersecurity risk management program, we participate in a variety of industry, governmental, and public-private information sharing channels. While these relationships enhance our situational awareness and provide avenues for cybersecurity information sharing, we may not receive complete or real-time information about all cybersecurity threats or vulnerabilities, including in instances where governmental entities or other external partners are unable to share data due to legal, operational, or security considerations. As a result, there may be circumstances in which our visibility into certain threat vectors is inherently limited. Our governance framework accounts for these constraints by incorporating layered monitoring, independent threat intelligence sources, and escalation protocols designed to mitigate potential lack of visibility and support timely decision-making associated with cybersecurity threats and vulnerabilities.

Our cybersecurity risk management program also attempts to assess third-party vendor, service provider, business partner and supply chain risk management issues. Our efforts aim to better understand the cybersecurity posture of our third-party vendors, service providers, business partners and suppliers by analyzing their cybersecurity risk management programs and results. Our third-party cybersecurity risk management processes include reviewing and revising our service provider and vendor management programs and the related agreements to require prompt notification of cyber incidents, outages and incidents to facilitate timely assessment, disclosure and action. Generally, our agreements require our third-party providers to abide by specific privacy, confidentiality and security processes, particularly for third-party data-processing activities. For vendors that offer software as a service solutions involving personal information, our third-party risk management program generally requires third-party attestation of their security practices such as a System and Organization Controls 2 report or ISO27001 certification. Our due diligence and selection processes also require third parties to complete a cybersecurity and data privacy questionnaire that includes questions about contractor track record. Our third-party security reviews are limited by their disclosures and specific negotiated contract terms; therefore, a risk-based approach is used in making vendor and contractual decisions based on those disclosures and the totality of the circumstances, such as whether the third party will have access to personal information or our network.

As of the date of this report, we are not aware of any risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations and financial condition. For further discussion of cybersecurity risks, see “Part I. Item 1A. Risk Factors – Risks Related to Our Business – Various events could disrupt or result in unauthorized access to our networks, information systems or properties and could impair our operating activities and negatively impact our reputation and financial results.”

Governance

Our organizational objectives are aligned to address our cybersecurity risks and management plays a pivotal role in assessing and managing our material risks from cybersecurity threats. Management’s role in assessing and managing material cybersecurity risks includes various management positions and committees responsible for assessing such risks. Our internal processes require escalation of material cybersecurity risks to our executive leadership and the Board of Directors of Charter, as well as management and committees who are tasked with the prevention, detection, mitigation and remediation of cybersecurity incidents. These processes provide guidance for consistent and effective incident handling and response and set standards for

internal notifications and escalations, as well as external notification considerations with respect to a cybersecurity event or incident requiring disclosure or notification to a state and/or federal agency or affected customers.

The Board of Directors of Charter has delegated to the Audit Committee oversight of our privacy and data security, including cybersecurity, risk exposures, policies and practices, including the steps management have taken to detect, monitor and control such risks and the potential impact of those exposures on our business, financial results, operations and reputation. Charter's Audit Committee receives quarterly updates on the enterprise risk management program, including information on cybersecurity risks and initiatives undertaken to identify, assess and mitigate such risks. A full cybersecurity review is conducted twice yearly with the Audit Committee and annually with the Board of Directors of Charter. This cybersecurity reporting may include threat and incident reporting, vulnerability detection reporting, risk mitigation metrics, systems and security operations updates or internal audit observations, if applicable.

We have a unified cybersecurity leadership team, composed of members of our Security Executive Steering Committee (“Security ESC”) to oversee implementation of appropriate cybersecurity protections and promote accountability. The Security ESC is led by senior executives in our technology organization and is comprised of senior executive leaders across the organization with the goal of driving cybersecurity focus through not just technical teams, but the entire business. The Security ESC reviews and evaluates current cyber threats and risks and improvements to our program and provides quarterly updates to the Chief Executive Officer as well as ad hoc updates on urgent matters. We also have a Cyber Security Council (“CSC”) and Security Operations Steering Committee that, under the direction of the Security ESC, collectively focus on cybersecurity across Charter and the overall protection of our internal network and related processes, policy, training and actions to protect customer and employee data. The CSC is comprised of senior leaders across the organization and operates under the auspices of the Security ESC, which is ultimately accountable under our enterprise risk management program for cybersecurity.

Our Executive Vice President, Chief Technology and Information Officer leads network technology, software development, security, technical integration, and information technology (“IT”). He has served in various software and engineering roles at Charter since 2016, and has previously held various IT roles, including chief information officer, at other telecommunications companies. Our Executive Vice President, Network Technology Services is responsible for operating our customer product technology infrastructure across our 41-state footprint. He has served in various network operations roles at Charter since 2016 and previously held various engineering roles at other large public companies. Both these leaders collectively oversee our cybersecurity program.

Our Chief Information Security Officer (“CISO”) is a Certified Information Systems Security Professional and has served in various roles in information security at Charter since 2020. He has over two decades of experience in cybersecurity, corporate security and network operations, including cyber threat intelligence, vulnerability management, security operations, incident response, information security engineering and architecture, risk management and security awareness.

Our principal physical assets consist of cable distribution plant and equipment, including signal receiving, encoding and decoding devices, headend reception facilities, distribution systems, and customer premise equipment for each of our cable systems. Our cable plant and related equipment are generally attached to utility poles under pole rental agreements with local public utilities and telephone companies, and in certain locations are buried in underground ducts or trenches. We own or lease real property for signal reception sites and own our service vehicles. We generally lease space for business offices. Our headend locations are located on owned or leased parcels of land. The physical components of our cable systems require maintenance as well as periodic upgrades to support the new services and products we introduce. See “Item 1. Business – Our Network Technology.” We believe that our properties are generally in good operating condition and are suitable for our business operations.

Overview

We are a leading broadband connectivity company with services available to 58 million homes and small to large businesses across 41 states through our Spectrum brand. Founded in 1993, we have evolved from providing cable TV to streaming, and from high-speed Internet to a converged broadband, WiFi and mobile experience. Over the Spectrum Fiber Broadband Network and supported by our 100% U.S.-based employees, we offer Seamless Connectivity and Entertainment with Spectrum Internet, Mobile, TV and Voice products. See “Part I. Item 1. Business — Products and Services” for further description of these services, including customer statistics for different services.

During the year ended December 31, 2025, we added 1.9 million mobile lines while Internet and video losses improved as compared to the prior year period. Sales were challenged by the competitive environment but were offset by lower customer churn. We remain focused on improving customer results through our brand platform, Life Unlimited which emphasizes the power of our advanced fiber-powered network and cutting-edge connectivity products and services, and our simplified pricing and packaging strategy that better utilizes our seamless connectivity and entertainment products to offer lower promotional and persistent bundled pricing to drive growth. Our Internet and mobile product bundles provide a differentiated connectivity experience by bringing together Spectrum Internet, Advanced WiFi and Unlimited Spectrum Mobile to offer consumers fast, reliable and secure online connections on their favorite devices at home and on the go in high-value packages. We have completed deals with major programmers to deliver better flexibility and greater value to our customers by including seamless entertainment applications with certain of our Spectrum TV packages at no additional cost. In July 2025, we began launching the sale of these seamless entertainment applications to customers on an à la carte basis, and we recently launched the Spectrum App Store, a digital storefront that helps customers activate, upgrade, buy and manage their streaming applications in one place. We also continue to evolve other elements of our video product and are deploying Xumo stream boxes to new video customers.

Our customer commitments focus on reliable connectivity, transparency, exceptional service and always improving. By continually improving our product set and offering consumers the opportunity to save money by switching to our services, we believe we can continue to penetrate our expanding footprint and sell additional products to our existing customers. We see operational benefits from the targeted investments we made in employee wages and benefits to build employee skill sets and tenure, as well as the continued investments in digitization of our customer service platforms, all with the goal of improving the customer experience, reducing transactions and driving customer growth and retention.

We spent $2.2 billion on our subsidized rural construction initiative during the year ended December 31, 2025 and activated approximately 483,000 subsidized rural passings. We currently offer Spectrum Internet products with speeds up to 1 Gbps across our entire footprint and multi-gigabit data speeds in a portion of our footprint. Our network evolution initiative remains on track to deliver symmetrical and multi-gigabit speeds across our entire footprint with convergence everywhere we operate.

We realized revenue, Adjusted EBITDA and income from operations during the periods presented as follows (in millions; all percentages are calculated using whole numbers; minor differences may exist due to rounding).

Adjusted EBITDA is defined as net income attributable to Charter shareholders plus net income attributable to noncontrolling interest, net interest expense, income taxes, depreciation and amortization, stock compensation expense, other income (expenses), net and other operating (income) expenses, net, such as special charges, merger and acquisition costs and (gain) loss on sale or retirement of assets. See “—Use of Adjusted EBITDA and Free Cash Flow” for further information on Adjusted EBITDA and free cash flow.

Total revenues decreased slightly primarily due to lower customers, higher seamless entertainment allocation and lower advertising sales, partly offset by mobile line growth and higher average revenue per customer. Adjusted EBITDA grew slightly with mobile revenues growing at a faster rate than mobile direct costs. Income from operations was further negatively impacted by an increase in loss on disposal of assets and merger and acquisition costs.

Approximately 89% of our revenues for each of the years ended December 31, 2025 and 2024 are attributable to monthly subscription fees charged to customers for our Internet, mobile, video, voice and commercial services as well as regional sports and news channels. Generally, these customer subscriptions may be discontinued by the customer at any time subject to a fee for certain commercial customers. The remaining 11% of our revenue is derived primarily from advertising revenues, franchise and other regulatory fee revenues (which are collected by us but then paid to local authorities), sales of mobile and video devices, processing fees or reconnection fees charged to customers to commence or reinstate service, installation, VOD and pay-per-view programming, and commissions related to the sale of merchandise by home shopping services.

Critical Accounting Policies and Estimates

Certain of our accounting policies require our management to make difficult, subjective and/or complex judgments. Management has discussed these policies with the Audit Committee of the Board of Directors of Charter, and the Audit Committee has reviewed the following disclosure. We consider the following policies to be the most critical in understanding the estimates, assumptions and judgments that are involved in preparing our financial statements, and the uncertainties that could affect our results of operations, financial condition and cash flows:

• Capitalization of labor and overhead costs

• Valuation and impairment of franchises and goodwill

• Income taxes

Capitalization of labor and overhead costs

Costs associated with network construction or upgrades, placement of the customer drop to the dwelling and the placement of outlets within a dwelling along with the costs associated with the deployment of new customer premise equipment necessary to provide Internet, video or voice services, are capitalized. Costs capitalized include materials, direct labor and certain indirect costs. These indirect costs consist of compensation and overhead costs associated with support functions. While our capitalization is based on specific activities, once capitalized, we track these costs on a composite b

Cross-currency derivative instruments are used to manage foreign exchange risk on the Sterling Notes by effectively converting £1.275 billion aggregate principal amount of fixed-rate British pound sterling denominated debt, including annual interest payments and the payment of principal at maturity, to fixed-rate U.S. dollar denominated debt. The fair value of our cross-currency derivatives included in other long-term liabilities on our consolidated balance sheets was $406 million and $504 million as of December 31, 2025 and 2024, respectively. For more information, see Note 13 to the accompanying consolidated financial statements contained in “Part II. Item 8. Financial Statements and Supplementary Data.”

As of December 31, 2025 and 2024, the weighted average interest rate on the credit facility debt was approximately 5.6% and 6.3%, respectively, and the weighted average interest rate on the senior notes was approximately 5.1% and 5.0%, respectively, resulting in a blended weighted average interest rate of 5.1% and 5.2%, respectively. The interest rate on approximately 87% and 89% of the total principal amount of our debt was fixed as of December 31, 2025 and 2024, respectively.

The table set forth below summarizes the fair values and contract terms of financial instruments subject to interest rate risk maintained by us as of December 31, 2025 (dollars in millions):

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

As of the end of the period covered by this report, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of the design and operation of disclosure controls and procedures with respect to the information generated for use in this annual report. The evaluation was based upon reports and certifications provided by a number of executives. Based on, and as of the date of that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective to provide reasonable assurances that information required to be disclosed in the reports we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

In designing and evaluating the disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based upon the above evaluation, we believe that our controls provide such reasonable assurances.

During the quarter ended December 31, 2025, there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) for the company. Our internal control system was designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements.

Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control — Integrated Framework (2013). Based on management’s assessment utilizing these criteria we believe that, as of December 31, 2025, our internal control over financial reporting was effective**.**

Our independent auditors, KPMG LLP, have audited our internal control over financial reporting as stated in their report as follows.

Opinion on Internal Control Over Financial Reporting

We have audited Charter Communications, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
