In September, Spectrum launched a new brand platform, Life Unlimited, which emphasizes the power of Spectrum’s advanced network and cutting-edge connectivity products and services to create opportunities and remove barriers to help customers live their best lives. As part of its new brand platform, Spectrum launched a new and simplified pricing and packaging strategy that better utilizes its seamless connectivity and entertainment products to offer lower promotional and persistent bundled pricing to drive growth. Additionally, Spectrum announced new customer commitments focused on reliable connectivity, transparency, exceptional service and a focus on always improving.
Fourth quarter total Internet customers decreased by 177,000, primarily driven by the end of the FCC's Affordable Connectivity Program ("ACP") in the second quarter and impacts of hurricanes in the fourth quarter, compared to a decline of 61,000 during the fourth quarter of 2023. Spectrum Internet® delivers the fastest Internet speeds 1 in the nation. Spectrum is evolving its connectivity network to offer symmetrical and multi-gigabit Internet speeds across its entire footprint and has launched symmetrical Internet service in eight markets. In January 2025, Spectrum launched 2x1 Gbps service in two markets. Unlike competitors, Spectrum upgrades its network for all households and can do so at a much lower cost. Spectrum 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 Spectrum Internet customers.
Total video customers decreased by 123,000 in the fourth quarter of 2024, compared to a decline of 257,000 in the fourth quarter of 2023, with the improvement driven by new and simplified pricing and packaging launched in September. As of December 31, 2024, Charter had 12.9 million total video customers. Spectrum TV Select video customers will soon receive up to approximately $80 per month of programmers' streaming application retail value at no extra cost, including the ad-supported versions of Max, Disney+, Peacock, Paramount+, ESPN+, AMC+, Discovery+, BET+, ViX, and Tennis Channel Plus. This programmer streaming application inclusion is part of Charter's broader video evolution strategy to provide flexible packages with enhanced value, whether through full packages with seamless entertainment, smaller video packages, or a suite of a-la-carte programmer application options for broadband-only customers.
During the fourth quarter of 2024, Charter added 529,000 total mobile lines, compared to growth of 546,000 during the fourth quarter of 2023. Spectrum Mobile TM is available to all new and existing Spectrum Internet customers and offers the fastest overall speeds,2 with plans that include 5G access, do not require contracts and include taxes and fees in the price. Spectrum Mobile is central to Charter's converged network strategy to provide consumers a differentiated connectivity experience with highly competitive, simple data plans and pricing.
During the fourth quarter of 2024, total wireline voice customers declined by 274,000, compared to a decline of 251,000 in the fourth quarter of 2023. As of December 31, 2024, Charter had 6.9 million total wireline voice customers.
Charter continues to work with federal, state and local governments to bring Spectrum Internet to unserved and underserved communities. During the fourth quarter of 2024, Charter activated 117,000 subsidized rural passings and 393,000 in 2024. Within Charter's subsidized rural footprint, total customer relationships increased by 41,000 in the fourth quarter of 2024.

Revenues
Fourth quarter revenue increased by 1.6% year-over-year to $13.9 billion, driven by growth in residential mobile service, advertising, other and residential Internet revenues, partly offset by lower residential video revenue and $37 million of total customer credits related to hurricanes Helene and Milton.
Residential revenue totaled $10.7 billion in the fourth quarter, a decrease of 0.4% year-over-year.
Fourth quarter 2024 monthly residential revenue per residential customer totaled $121.40, and increased by 1.7% compared to the prior year period. The growth was driven by promotional rate step-ups, rate adjustments and the growth of Spectrum Mobile, partly offset by a lower mix of video customer relationships, a higher mix of lower priced video packages within Charter's video customer base, $37 million of costs which accounting principles require be allocated to programmer streaming applications and netted within video revenue and $34 million of residential customer credits related to hurricanes Helene and Milton.
Internet revenue grew by 0.9% year-over-year to $5.9 billion, driven by promotional rate step-ups and rate adjustments, partly offset a decline in Internet customers during the last year and customer credits related to hurricanes Helene and Milton.
Video revenue totaled $3.6 billion in the fourth quarter, a decrease of 7.4% compared to the prior year period, driven by a decline in video customers during the last year, a higher mix of lower priced video packages within Charter's video customer base and $37 million of costs which accounting principles require

be allocated to programmer streaming applications and netted within video revenue, partly offset by promotional rate step-ups and video rate adjustments that pass through programmer rate increases.
Fourth quarter mobile service revenue totaled $860 million, an increase of 37.4% year-over-year, driven by mobile line growth and mobile service revenue per line growth.
Voice revenue decreased by 10.4% year-over-year to $353 million, driven by a decline in wireline voice customers over the last twelve months, partly offset by voice rate adjustments.
Commercial revenue increased by 1.9% year-over-year to $1.8 billion, driven by enterprise and SMB revenue growth of 4.4% and 0.3% year-over-year, respectively. The year-over-year increase in fourth quarter 2024 SMB revenue was driven by higher monthly SMB revenue per SMB customer, primarily due to rate adjustments. Enterprise revenue excluding wholesale increased by 5.2% year-over-year, mostly reflecting PSU growth.
Fourth quarter advertising sales revenue of $540 million increased by 26.4% compared to the year-ago quarter, primarily driven by higher political revenue. Excluding political revenue in both periods, advertising sales revenue decreased by 8.2% year-over-year due to a more challenged local and national advertising market.
Other revenue totaled $884 million in the fourth quarter, an increase of 14.6% compared to the fourth quarter of 2023, primarily driven by higher mobile device sales.
Operating Costs and Expenses
Fourth quarter programming costs decreased by $229 million, or 9.1% as compared to the fourth quarter of 2023, reflecting fewer video customers, a higher mix of lower cost packages within Charter's video customer base and $37 million of costs which accounting principles require be allocated to programmer streaming applications and netted within video revenue, partly offset by contractual programming rate increases and renewals.
Other costs of revenue increased by $244 million, or 16.2% year-over-year, primarily driven by higher mobile device sales and mobile service direct costs, and higher advertising sales expense related to political revenue.
Field and technology operations increased by $11 million, or 0.9% year-over-year.
Customer operations decreased by $21 million, or 2.6% year-over-year, primarily due to lower labor costs.
Sales and marketing expenses increased by $30 million, or 3.2% year-over-year, given Spectrum's continued focus on driving growth and the launch of its new brand platform, Life Unlimited.
Other expenses decreased by $7 million, or 0.7% as compared to the fourth quarter of 2023.
Net Income Attributable to Charter Shareholders
Net income attributable to Charter shareholders totaled $1.5 billion in the fourth quarter of 2024, compared to $1.1 billion in the fourth quarter of 2023, due to a larger pension remeasurement loss in the prior year period and higher Adjusted EBITDA.
Net income per basic common share attributable to Charter shareholders totaled $10.32 in the fourth quarter of 2024 compared to $7.23 during the same period last year. The increase was primarily the
5

result of the factors described above in addition to a 2.9% decrease in basic weighted average common shares outstanding versus the prior year period.
Adjusted EBITDA
Fourth quarter Adjusted EBITDA of $5.8 billion grew by 3.4% year-over-year, reflecting growth in revenue and operating expenses of 1.6% and 0.3%, respectively.
Capital Expenditures
Capital expenditures totaled $3.1 billion in the fourth quarter of 2024, an increase of $206 million compared to the fourth quarter of 2023, driven by higher spend on line extensions, CPE (timing of equipment purchases) and scalable infrastructure. Line extensions capital expenditures totaled $1.1 billion in the fourth quarter of 2024, driven by Charter's subsidized rural construction initiative and continued network expansion across residential and commercial greenfield and market fill-in opportunities.
Charter currently expects full year 2025 capital expenditures to total approximately $12 billion, including line extensions capital expenditures of approximately $4.2 billion and network evolution spend of approximately $1.5 billion. The actual amount of capital expenditures in 2025 will depend on a number of factors including, but not limited to, the pace of Charter's network evolution and expansion initiatives, supply chain timing and growth rates in Charter's residential and commercial businesses.
Cash Flow and Free Cash Flow
During the fourth quarter of 2024, net cash flows from operating activities totaled $3.5 billion, a decrease from $3.9 billion in the prior year. The year-over-year decline was primarily driven by a more unfavorable change in working capital, higher cash taxes and cash interest, partly offset by higher Adjusted EBITDA.
Free cash flow in the fourth quarter of 2024 totaled $984 million, a decrease of $77 million compared to the fourth quarter of 2023. The year-over-year decline in free cash flow was primarily driven by lower net cash flows from operating activities and higher capital expenditures, partly offset by a more favorable change in accrued expenses related to capital expenditures.
Liquidity & Financing
As of December 31, 2024, total principal amount of debt was $93.8 billion and Charter's credit facilities provided approximately $6.3 billion of additional liquidity in excess of Charter's $459 million cash position.
On December 3, 2024, Charter announced that its subsidiary, Charter Communications Operating, LLC, had entered into an amendment to its existing Credit Agreement that extends the maturity date of a significant portion of debt due in 2027 to maturity dates in 2030 and 2031.
Share Repurchases
During the three months ended December 31, 2024, Charter purchased 292 thousand shares of Charter Class A common stock and Charter Holdings common units for $113 million.

Additional Information Available on Website
The information in this press release should be read in conjunction with the financial statements and footnotes contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, which will be posted on the “Results & SEC Filings” section of the Company's investor relations website at ir.charter.com, when it is filed with the Securities and Exchange Commission (the "SEC"). A slide presentation to accompany the conference call and a trending schedule containing historical customer and financial data will also be available in the “Results & SEC Filings” section.
Use of Adjusted EBITDA and Free Cash Flow Information
The Company uses certain measures that are not defined by U.S. generally accepted accounting principles ("GAAP") to evaluate various aspects of its business. Adjusted EBITDA and free cash flow are non-GAAP financial measures and should be considered in addition to, not as a substitute for, net income attributable to Charter shareholders and net cash flows from operating activities reported in accordance with GAAP. These terms, as defined by Charter, may not be comparable to similarly titled measures used by other companies. Adjusted EBITDA and free cash flow are reconciled to net income attributable to Charter shareholders and net cash flows from operating activities, respectively, in the Addendum to this release.
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 and (gain) loss on sale or retirement of assets. As such, it eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of the Company's businesses as well as other non-cash or special items, and is unaffected by the Company's capital structure or investment activities. However, this measure is limited in that it does not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues and the cash cost of financing. These costs are evaluated through other financial measures.
Free cash flow is defined as net cash flows from operating activities, less capital expenditures and changes in accrued expenses related to capital expenditures.
Management and Charter's board of directors use Adjusted EBITDA and free cash flow to assess Charter's performance and its ability to service its debt, fund operations and make additional investments with internally generated funds. In addition, Adjusted EBITDA generally correlates to the leverage ratio calculation under the Company's credit facilities or outstanding notes to determine compliance with the covenants contained in the facilities and notes (all such documents have been previously filed with the SEC). For the purpose of calculating compliance with leverage covenants, the Company uses Adjusted EBITDA, as presented, excluding certain expenses paid by its operating subsidiaries to other Charter entities. The Company's debt covenants refer to these expenses as management fees, which were $375 million and $378 million for the three months ended December 31, 2024 and 2023, respectively, and $1.5 billion and $1.4 billion for the years ended December 31, 2024 and 2023, respectively.

CHARTER COMMUNICATIONS, INC. AND SUBSIDIARIES
FOOTNOTES
(a)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 and (gain) loss on sale or retirement of assets. As such, it eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of our businesses as well as other non-cash or special items, and is unaffected by our capital structure or investment activities. Free cash flow is defined as net cash flows from operating activities, less capital expenditures and changes in accrued expenses related to capital expenditures.
(b)The previously reported “Costs to Service Customers” expense category has been separated between “Field and Technology Operations” and “Customer Operations” for all periods presented with the adoption of FASB's Accounting Standards Update No. 2023-07, Improvements to Reportable Segment Disclosures. The new presentation does not result in any changes to total operating expenses or Adjusted EBITDA for any period presented. Other expense excludes stock compensation expense. Total operating costs and expenses excludes stock compensation expense, depreciation and amortization and other operating (income) expenses, net.
(c)We calculate the aging of customer accounts based on the monthly billing cycle for each account in accordance with our collection policies. On that basis, at December 31, 2024, September 30, 2024 and December 31, 2023, customers included approximately 102,500, 127,300 and 135,800 customers, respectively, whose accounts were over 60 days past due, approximately 12,100, 11,900 and 54,700 customers, respectively, whose accounts were over 90 days past due and approximately 13,600, 11,800 and 286,000 customers, respectively, whose accounts were over 120 days past due. The decrease in accounts past due is predominately due to revisions to customer account balances associated with the end of the Federal Communications Commission's Affordable Connectivity Program, including balance write-offs and conversion to payment plans.
(d)Passings represent our estimate of the number of units, such as single family homes, apartment and condominium units and SMB and enterprise sites passed by our cable distribution network in the areas where we offer the service indicated. These estimates are based upon the information available at this time and are updated for all periods presented when new information becomes available. In the fourth quarter of 2024, we completed a review of our passings which resulted in a net reduction of approximately 1.7 million passings for all periods presented.
(e)Customer relationships include the number of customers that receive one or more levels of service, encompassing Internet, video, mobile and voice services, without regard to which service(s) such customers receive. Customers who reside in residential multiple dwelling units ("MDUs") and that are billed under bulk contracts are counted based on the number of billed units within each bulk MDU. Total customer relationships exclude enterprise and mobile-only customer relationships.
(f)Penetration represents residential and SMB customers as a percentage of estimated passings. Penetration excludes mobile-only customers.
(g)Monthly residential revenue per residential customer is calculated as total residential quarterly revenue divided by three divided by average residential customer relationships during the respective quarter and excludes mobile-only customer relationships.
(h)Monthly SMB revenue per SMB customer is calculated as total SMB quarterly revenue divided by three divided by average SMB customer relationships during the respective quarter and excludes mobile-only customer relationships.
(i)One product, two product and three or more product penetration represents the number of residential customers that subscribe to one product, two products or three or more products, respectively, as a percentage of residential customer relationships, excluding mobile-only customers.
(j)Mobile lines include phones and tablets which require one of our standard rate plans (e.g., "Unlimited" or "By the Gig"). Mobile lines exclude wearables and other devices that do not require standard phone rate plans.
(k)Enterprise PSUs represents the aggregate number of fiber service offerings counting each separate service offering at each customer location as an individual PSU.
(l)Customer premise equipment includes equipment and devices located at the customer's premise used to deliver our Internet, video and voice services (e.g., modems, routers and set-top boxes), as well as installation costs.
(m)Scalable infrastructure includes costs, not related to customer premise equipment or our network, to secure growth of new customers or provide service enhancements (e.g., headend equipment).
(n)Upgrade/rebuild includes costs to modify or replace existing fiber/coaxial cable networks, including our network evolution initiative.
(o)Support capital includes costs associated with the replacement or enhancement of non-network assets (e.g., back-office systems, non-network equipment, land and buildings, vehicles, tools and test equipment).
(p)Line extensions include network costs associated with entering new service areas (e.g., fiber/coaxial cable, amplifiers, electronic equipment, make-ready and design engineering).
(q)The subsidized rural construction initiative subcategory includes projects for which we are receiving subsidies from federal, state and local governments, excluding customer premise equipment and installation.
