Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Summary of Significant Accounting Policies Revenue Recognition Residential Services We derive revenue through monthly charges to residential customers of our broadband, video, and telephony services, including installation services. In addition, we derive revenue from digital video recorder, video-on-demand, pay-per-view, and home shopping commissions which are reflected in "Residential video" revenues. We recognize broadband, video, and telephony revenues as the services are provided to a customer on a monthly basis. Each service is accounted for as a distinct performance obligation. Revenue from the sale of bundled services at a discounted rate is allocated to each product based on the standalone selling price of each performance obligation within the bundled offer. The standalone selling price requires judgment and is typically determined based on the current prices at which the separate services are sold by us. Installation revenue for our residential services is deferred and recognized over the benefit period, which is generally less than one year. The estimated benefit period takes into account both quantitative and qualitative factors including the significance of average installation fees to total recurring revenue per customer. Also, we offer mobile services providing data, talk and text to consumers in or near our service areas. Customers are billed monthly for access to and usage of our mobile services. We recognize mobile service revenue ratably over the monthly service period as the services are provided to the customers. We are assessed non-income related taxes by governmental authorities, including franchising authorities (generally under multi-year agreements), and collect such taxes from our customers. In instances where the tax is being assessed directly on us, amounts paid to the governmental authorities are recorded as programming and other direct costs and amounts received from the customers are recorded as revenue. For the years ended December 31, 2024, 2023 and 2022, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $212,207, $219,988 and $232,795, respectively. Business and Wholesale Revenue We derive revenue from the sale of products and services to both large enterprise and small and medium-sized business ("SMB") customers, including broadband, telephony, networking, video services and mobile reflected in "Business services and wholesale" revenues. Our business services also include ethernet, data transport, and IP-based virtual private networks. We provide managed services to businesses, including hosted telephony services (cloud based SIP-based private branch exchange), managed WiFi, managed desktop and server backup and managed collaboration services including audio and web conferencing. We also offer fiber-to-the-tower services to wireless carriers for cell tower backhaul, which enables wireline communications service providers to connect to customers that their own networks do not reach. We recognize revenues for these services as the services are provided to a customer on a monthly basis. Substantially all of our SMB customers are billed monthly and large enterprise customers are billed in accordance with the terms of their contracts which is typically on a monthly basis. Contracts with large enterprise customers typically range from three News and Advertising Revenue News and advertising revenue is primarily derived from the sale of (i) advertising inventory available on the programming carried on our cable television systems, as well as other systems (linear revenue), (ii) digital advertising, (iii) data analytics, and (iv) affiliation fees for news programming. As part of the agreements under which we acquire video programming, we typically receive an allocation of scheduled advertising time during such programming into which our cable systems can insert commercials. In several of the markets in which we operate, we have entered into agreements commonly referred to as interconnects with other cable operators to jointly sell local advertising. In some of these markets, we represent the advertising sales efforts of other cable operators; in other markets, other cable operators represent us. We also offer customers the opportunity to advertise on digital platforms. Advertising revenues are recognized when the advertising is distributed. For arrangements in which we control the sale of advertising and act as the principal to the transaction, we recognize revenue earned from the advertising customer on a gross basis and the amount remitted to the distributor as an operating expense. For arrangements in which we do not control the sale of advertising and act as an agent to the transaction, we recognize revenue net of any fee remitted to the distributor. Revenue earned from the data-driven, audience-based advertising solutions using advanced analytics tools is recognized when services are provided. Affiliation fee revenue derived by our news business is recognized as the programming services are provided. Other Revenue Other revenue includes revenue derived from the sale of mobile devices which is recognized upon delivery and acceptance of the equipment by the customer. Under our mobile device payment plan, the customer is sold the device in exchange for a non-interest-bearing installment note, which is repaid by the customer, typically over a 36-month term, and concurrently enters into a month-to-month contract for mobile service. We may offer certain promotions regarding mobile devices that provide billing credits applied over a specified term, contingent upon the customer maintaining service. These credits are included in the transaction price, which are allocated to the performance obligations based on their relative selling price and are recognized when earned. Revenues derived from other sources are recognized when services are provided or events occur. Customer Contract Costs Incremental costs incurred in obtaining a contract with a customer are deferred and recorded as an asset if the period of benefit is expected to be greater than one year. Sales commissions for enterprise customers are deferred and amortized over the average contract term. As the amortization period for sales commission expenses related to residential and SMB customers is less than one year, we utilize the practical expedient and are recognizing the costs when incurred. The costs of fulfilling a contract with a customer are deferred and recorded as an asset if they generate or enhance resources for us that will be used in satisfying future performance obligations and are expected to be recovered. Installation costs related to residential and SMB customers that are not capitalized as part of the initial deployment of new customer premise equipment are expensed as incurred pursuant to industry-specific guidance. Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheet and totaled $19,743 and $18,109 as of December 31, 2024 and 2023, respectively. A significant portion of our revenue is derived from residential and SMB customer contracts which are month-to month. As such, the amount of revenue related to unsatisfied performance obligations is not necessarily indicative of the future revenue to be recognized from our existing customer base. Contracts with enterprise customers generally range from three years to five years, and services may only be terminated in accordance with the contractual terms. The following table presents the composition of revenue: Years Ended December 31, 2024 2023 2022 Residential: Broadband $ 3,645,460 $ 3,824,472 $ 3,930,667 Video 2,896,600 3,072,011 3,281,306 Telephony 277,938 300,198 332,406 Mobile 117,084 77,012 61,832 Residential revenue 6,937,082 7,273,693 7,606,211 Business services and wholesale 1,471,764 1,467,149 1,474,269 News and advertising 486,172 447,742 520,293 Other 59,399 48,480 46,886 Total revenue $ 8,954,417 $ 9,237,064 $ 9,647,659 Multiple-Element Transactions In the normal course of business, we may enter into multiple-element transactions where we are simultaneously both a customer and a vendor with the same counterparty or in which we purchase multiple products and/or services, or settle outstanding items contemporaneously with the purchase of a product or service, from a single counterparty. Our policy for accounting for each transaction negotiated contemporaneously is to record each deliverable of the transaction based on our best estimate of selling price in a manner consistent with that used to determine the price to sell each deliverable on a standalone basis. In determining the value of the respective deliverable, we utilize historical transactions, quoted market prices (as available), or comparable transactions. Programming and Other Direct Costs Costs of revenue related to delivery of services and goods are classified as "programming and other direct costs" in the accompanying consolidated statements of operations. Programming Costs Programming expenses related to our video service represent fees paid to programming distributors to license the programming distributed to video customers. This programming is acquired generally under multi-year distribution agreements, with rates usually based on the number of customers that receive the programming. If there are periods when an existing distribution agreement has expired and the parties have not finalized negotiations of either a renewal of that agreement or a new agreement for certain periods of time, we often continue to carry and pay for these services until execution of definitive replacement agreements or renewals. The amount of programming expense recorded during the interim period is based on our estimate of the ultimate contractual agreement expected to be reached, which is based on several factors, including previous contractual rates, customary rate increases and the current status of negotiations. Such estimates are adjusted as negotiations progress until new programming terms are finalized. In addition, we receive, or may receive, incentives from programming distributors for carriage of the distributors' programming. We generally recognize these incentives as a reduction of programming costs and are recorded in "programming and other direct costs", generally over the term of the distribution agreement. Advertising Expenses Advertising costs are charged to expense when incurred and are reflected in "other operating expenses" in the accompanying consolidated statements of operations. Advertising costs amounted to $263,529, $253,777 and $299,590 for the years ended December 31, 2024, 2023 and 2022, respectively. Share-Based Compensation Share-based compensation expense which primarily relates to awards of stock options, restricted shares, and performance stock units, is based on the fair value of share-based payment awards at the date of grant. We recognize share-based compensation expense over the requisite service period or when it is probable any related performance condition will be met. For awards with graded vesting, compensation cost is recognized on an accelerated method under the graded vesting method over the requisite service period. Share-based compensation expense related to awards that vest entirely at the end of the vesting period are expensed on a straight-line basis. We account for forfeitures as they occur. See Note 15 to the consolidated financial statements for additional information about our share-based compensation. Income Taxes Our provision for income taxes is based on current period income, changes in deferred tax assets and liabilities and changes in estimates with regard to uncertain tax positions. Deferred tax assets are subject to an ongoing assessment of realizability. Cash and Cash Equivalents Our cash investments are placed with money market funds and financial institutions that are investment grade as rated by S&P Global Ratings and Moody's Investors Service. We select money market funds that predominantly invest in marketable, direct obligations issued or guaranteed by the United States government or its agencies, commercial paper, fully collateralized repurchase agreements, certificates of deposit, and time deposits. We consider the balance of our investment in funds that substantially hold securities that mature within three months or less from the date the fund purchases these securities to be cash equivalents. The carrying amount of cash and cash equivalents either approximates fair value due to the short-term maturity of these instruments or are at fair value. Accounts Receivable Accounts receivable are recorded at net realizable value. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amounts. Investment Securities Investment securities are carried at fair value with realized and unrealized holding gains and losses included in the consolidated statements of operations. Long-Lived Assets and Amortizable Intangible Assets Property, plant and equipment, including construction materials, are carried at cost, and include all direct costs and certain indirect costs associated with the construction of cable systems, and the costs of new equipment installations. Equipment under finance leases is recorded at the present value of the total minimum lease payments. Depreciation on equipment is calculated on the straight-line basis over the estimated useful lives of the assets or, with respect to equipment under finance lease obligations and leasehold improvements, amortized over the lease term or the assets' useful lives and reported in depreciation and amortization in the consolidated statements of operations. We capitalize certain internal and external costs incurred to acquire or develop internal-use software. Capitalized software costs are amortized over the estimated useful life of the software and reported in depreciation and amortization. Customer relationships, trade names and other intangibles established in connection with acquisitions that are finite-lived are amortized in a manner that reflects the pattern in which the projected net cash inflows are expected to occur, such as the sum of the years' digits method, or when such pattern does not exist, using the straight-line method over their respective estimated useful lives. We review our long-lived assets (property, plant and equipment, and intangible assets subject to amortization) for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value. Goodwill and Indefinite-Lived Intangible Assets Goodwill and the value of indefinite-lived cable franchise rights acquired in business combinations are not amortized. Rather, such assets are tested for impairment annually or whenever events or changes in circumstances indicate that it is more likely than not that the assets may be impaired. The assessment of recoverability may first consider qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit or the indefinite-lived cable franchise right is less than its carrying amount. These qualitative factors include macroeconomic conditions such as changes in interest rates, industry and market considerations, recent and projected financial performance of the reporting units, as well as other factors. A quantitative test is performed if we conclude that it is more likely than not that the fair value of a reporting unit or an indefinite-lived cable franchise right is less than its carrying amount or if a qualitative assessment is not performed. In 2024, we performed quantitative assessments for our goodwill and our indefinite-lived cable franchise rights recoverability tests. In 2023, we performed a quantitative assessment for our goodwill recoverability test and a qualitative assessment for our indefinite-lived cable franchise rights recoverability test. See Note 10 for a discussion of the results of our annual impairment tests. Goodwill Goodwill resulted from business combinations and represents the excess amount of the consideration paid over the identifiable assets and liabilities recorded in the acquisition. We test goodwill for impairment at the reporting unit level: (i) Telecommunications and (ii) News and Advertising. The quantitative test for goodwill identifies potential impairment by comparing the fair value of the reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. We estimate the fair value of our reporting units by considering both (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which is based on the expected normalized cash flows of the reporting units following the discrete projection period, and (ii) a market approach, which includes the use of multiples of publicly-traded companies whose services are comparable to ours. Significant judgments in estimating the fair value of our reporting units include cash flow projections and the selection of the discount rate. The estimates and assumptions utilized in estimating the fair value of our reporting units could have a significant impact on whether an impairment charge is recognized and also the magnitude of any such charge. Fair value estimates are made at a specific point in time, based on relevant information. These estimates are subjective in nature and involve uncertainties and matters of significant judgments. Changes in assumptions could significantly affect the estimates. Indefinite-lived Cable Franchise Rights Our indefinite-lived cable franchise rights reflect the value of agreements we have with state and local governments that allow us to construct and operate a cable business within a specified geographic area and allow us to solicit and service potential customers in the service areas defined by the franchise rights currently held by us. We have concluded that our cable franchise rights have an indefinite useful life since there are no legal, regulatory, contractual, competitive, economic or other factors that limit the period over which these rights will contribute to our cash flows. For impairment testing purposes, we have concluded that our cable franchise rights are a single unit of account. When the qualitative assessment is not used, or if the qualitative assessment is not conclusive, the impairment test for our indefinite-lived cable franchise rights requires a comparison of the estimated fair value of the cable franchise rights with its carrying value. If the carrying value of the indefinite-lived cable franchise rights exceed its fair value, an impairment loss is recognized in an amount equal to that excess. Estimates and assumptions utilized in estimating the fair value of our indefinite-lived cable franchise rights could have a significant impact on whether an impairment charge is recognized and also the magnitude of any such charge. Fair value estimates are made at a specific point in time, based on relevant information. These estimates are subjective in nature and involve uncertainties and matters of significant judgments. Changes in assumptions could significantly affect the estimates. Deferred Financing Costs Deferred financing costs, which are presented as a reduction of debt, are amortized to interest expense using the effective interest method over the terms of the related debt. Derivative Financial Instruments We account for derivative financial instruments as either assets or liabilities measured at fair value. We currently use derivative instruments to manage our exposure to market risks from interest rates. Through January 2023 we used derivative instruments to manage our exposure against equity price risk on shares of Comcast Corporation ("Comcast") common stock we previously owned. We do not hold or issue derivative instruments for speculative or trading purposes. Our derivative instruments are not designated as hedges, and changes in the fair values of these derivatives are recognized in the consolidated statements of operations as gain (loss) on derivative contracts or gain (loss) on interest rate swap contracts. Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when we believe it is probable that a liability has been incurred and the amount of the contingency can be reasonably estimated. Foreign Currency Certain of our subsidiaries (including our international news channel and our customer care center) are located outside the United States. The functional currency for these subsidiaries is determined based on the primary economic environment in which the subsidiary operates. Revenues and expenses for these subsidiaries are translated into U.S. dollars using rates that approximate those in effect during the period and the assets and liabilities are translated into U.S. dollars using exchange rates in effect at the end of each period. The resulting gains and losses from these translations are recognized in cumulative translation adjustment included in accumulated other comprehensive income (loss) in stockholders’/member's equity (deficiency) on the consolidated balance sheets. Common Stock of Altice USA Each holder of our Class A common stock has one vote per share while holders of our Class B common stock have twenty-five votes per share. Class B shares can be converted to Class A common stock at anytime with a conversion ratio of one Class A common share for one Class B common share. The following table provides details of Altice USA's shares of common stock outstanding: Shares of Common Stock Outstanding Class A Class B Balance at December 31, 2022 271,833,063 184,329,229 Conversion of Class B common stock to Class A common stock 104,801 (104,801) Issuance of common shares in connection with the vesting of restricted stock units 1,357,983 — Retirement of Class A common shares due to forfeiture (1,522,965) — Treasury shares reissued 96 — Balance at December 31, 2023 271,772,978 184,224,428 Conversion of Class B common stock to Class A common stock 413 (413) Issuance of common shares in connection with the vesting of restricted stock units 5,224,768 — Issuance of common shares in connection with the vesting of deferred cash awards, net of shares recorded as Treasury stock 1,982,371 — Balance at December 31, 2024 278,980,530 184,224,015 CSC Holdings Membership Interests As of December 31, 2024 and 2023, CSC Holdings had 100 membership units issued and outstanding, which are all indirectly owned by Altice USA. Dividends and Distributions Altice USA Altice USA may pay dividends on its capital stock only from net profits and surplus as determined under Delaware law. If dividends are paid on the Altice USA common stock, holders of the Altice USA Class A common stock and Altice USA Class B common stock are entitled to receive dividends, and other distributions in cash, stock or property, equally on a per share basis, except that stock dividends with respect to Altice USA Class A common stock may be paid only with shares of Altice USA Class A common stock and stock dividends with respect to Altice USA Class B common stock may be paid only with shares of Altice USA Class B common stock. Our indentures restrict the amount of dividends and distributions in respect of any equity interest that can be made. During 2024, 2023 and 2022, there were no dividends paid to shareholders by Altice USA. CSC Holdings CSC Holdings may make distributions on its membership interests only if sufficient funds exist as determined under Delaware law. See Note 16 for a discussion of equity distributions that CSC Holdings made to its parent. Concentrations of Credit Risk Financial instruments that may potentially subject us to a concentration of credit risk consist primarily of cash and cash equivalents and trade account receivables. We monitor the financial institutions and money market funds where it invests its cash and cash equivalents with diversification among counterparties to mitigate exposure to any single financial institution. Our emphasis is primarily on safety of principal and liquidity and secondarily on maximizing the yield on its investments. Management believes that no significant concentration of credit risk exists with respect to its cash and cash equivalents because of its assessment of the creditworthiness and financial viability of the respective financial institutions. We did not have a single customer that represented 10% or more of our consolidated revenues for the years ended December 31, 2024, 2023 and 2022 or 10% or more of our consolidated net trade receivables at December 31, 2024, and 2023, respectively. Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See Note 13 for a discussion of fair value estimates. Reclassifications Certain reclassifications have been made to the 2023 and 2022 amounts to conform to the 2024 presentation.

Earnings Per Share

Earnings Per Share	12 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	NET INCOME (LOSS) PER SHARE Basic net income per common share attributable to Altice USA stockholders is computed by dividing net income attributable to Altice USA stockholders by the weighted average number of common shares outstanding during the period. Diluted income per common share attributable to Altice USA stockholders reflects the dilutive effects of stock options, restricted stock, restricted stock units, and deferred cash-denominated awards. For awards that are performance based, the dilutive effect is reflected upon the achievement of the performance criteria. Diluted net loss per common share attributable to Altice USA stockholders excludes the effects of common stock equivalents as they are anti-dilutive. The following table presents a reconciliation of weighted average shares used in the calculations of the basic and diluted net income per share attributable to Altice USA stockholders: Years Ended December 31, 2024 2023 2022 (in thousands) Basic weighted average shares outstanding 459,888 454,723 453,244 Effect of dilution: Stock options — — — Restricted stock — 74 38 Restricted stock units — — — Deferred cash-denominated awards (Note 15) — 237 — Diluted weighted average shares outstanding 459,888 455,034 453,282 Weighted average shares excluded from diluted weighted average shares outstanding: Anti-dilutive shares 32,488 46,084 57,961 Share-based compensation awards whose performance metrics have not been achieved 23,950 20,831 7,309 Net income (loss) per membership unit for CSC Holdings is not presented since CSC Holdings is a limited liability company and a wholly-owned subsidiary of Altice USA.

Property, Plant and Equipment [Abstract]
PROPERTY, PLANT AND EQUIPMENT	PROPERTY, PLANT AND EQUIPMENT Costs incurred in the construction of our cable systems, including line extensions to, and upgrade of, our hybrid fiber/coaxial infrastructure and construction of the parallel fiber-to-the-home ("FTTH") infrastructure, are capitalized. This includes headend facilities and initial placement of the feeder cable to connect a customer that had not been previously connected. These costs consist of materials, subcontractor labor, direct consulting fees, and internal labor and related costs associated with the construction activities (including interest related to FTTH construction). Internal costs that are capitalized consist of salaries and benefits of our employees and a portion of facility costs that supports the construction activities. Such costs are depreciated over the estimated life of our infrastructure and our headend facilities and related equipment (5 to 25 years). Costs of operating the plant and the technical facilities, including repairs and maintenance, are expensed as incurred. Costs associated with the initial deployment of new customer premise equipment ("CPE") necessary to provide services are also capitalized. These costs include materials, subcontractor labor, internal labor, and other related costs associated with the connection activities. Departmental activities supporting the connection process are capitalized based on time-weighted activity allocations of costs. These installation costs are amortized over the estimated useful lives of the CPE. The portion of departmental costs related to disconnecting services and removing CPE from a customer, costs related to connecting CPE that has been previously connected to the network, and repairs and maintenance are expensed as incurred. The estimated useful lives assigned to our property, plant and equipment are reviewed on an annual basis or more frequently if circumstances warrant and such lives are revised to the extent necessary due to changing facts and circumstances. Any changes in estimated useful lives are reflected prospectively. Property, plant and equipment (including equipment under finance leases) consist of the following assets, which are depreciated or amortized on a straight-line basis over the estimated useful lives shown below: December 31, Estimated 2024 2023 Customer premise equipment $ 2,404,889 $ 2,242,175 3 to 5 years Headends and related equipment 2,475,499 2,506,665 5 to 25 years Infrastructure 9,298,328 8,720,446 5 to 25 years Equipment and software 1,607,236 1,436,010 3 to 10 years Construction in progress (including materials and supplies) 328,033 360,551 Furniture and fixtures 82,150 80,585 5 to 8 years Transportation equipment 139,627 123,193 5 to 10 years Buildings and building improvements 592,421 574,162 10 to 40 years Leasehold improvements 198,449 187,608 Term of lease Land 50,014 48,804 17,176,646 16,280,199 Less accumulated depreciation and amortization (8,762,014) (8,162,442) $ 8,414,632 $ 8,117,757 For the years ended December 31, 2024, 2023 and 2022, we capitalized certain costs aggregating $255,942, $147,267 and $138,845, respectively, related to the acquisition and development of internal use software, which are included in the table above. Depreciation expense on property, plant and equipment (including finance leases) for the years ended December 31, 2024, 2023 and 2022 amounted to $1,326,388, $1,252,919 and $1,218,365, respectively, including losses related to the disposal of plant and equipment and accelerated depreciation.

LEASES

Leases [Abstract]
LEASES	LEASES Our operating leases are comprised primarily of facility leases and our finance leases are comprised primarily of vehicle and equipment leases. We determine if an arrangement is a lease at inception and lease assets and liabilities are recognized upon commencement of the lease based on the present value of the future minimum lease payments over the lease term. Lease assets and liabilities are not recorded for leases with an initial term of one year or less. We generally use our incremental borrowing rate as the discount rate for leases, unless an interest rate is implicitly stated in the lease agreement. The lease term will include options to extend the lease when it is reasonably certain that we will exercise that option. Balance sheet information related to our leases is presented below: Balance Sheet location December 31, 2024 2023 Operating leases: Right-of-use lease assets Right-of-use operating lease assets $ 248,013 $ 255,545 Right-of-use lease liability, current Other current liabilities 45,091 47,965 Right-of-use lease liability, long-term Right-of-use operating lease liability 255,116 264,647 Finance leases: Right-of-use lease assets Property, plant and equipment 232,117 326,427 Right-of-use lease liability, current Current portion of long-term debt 77,770 123,636 Right-of-use lease liability, long-term Long-term debt 67,592 104,720 The following provides details of our lease expense: Years Ended December 31, 2024 2023 Operating lease expense, net $ 59,429 $ 62,157 Finance lease expense: Amortization of assets 81,289 95,449 Interest on lease liabilities 15,462 14,912 Total finance lease expense 96,751 110,361 $ 156,180 $ 172,518 Other information related to our leases is presented below: As of December 31, 2024 2023 Right-of-use assets acquired in exchange for operating lease obligations $ 41,002 $ 60,108 Cash Paid For Amounts Included In Measurement of Liabilities: Operating cash flows from finance leases 15,462 14,912 Operating cash flows from operating leases 69,818 63,737 Weighted Average Remaining Lease Term: Operating leases 7.9 years 8.2 years Finance leases 3.1 years 2.2 years Weighted Average Discount Rate: Operating leases 5.72 % 5.70 % Finance leases 8.17 % 7.78 % The minimum future annual payments under non-cancellable leases during the next five years and thereafter, at rates now in force, are as follows: Finance leases Operating leases 2025 $ 85,492 $ 55,335 2026 34,967 55,731 2027 13,413 52,561 2028 12,174 42,746 2029 7,881 37,745 Thereafter 7,081 134,882 Total future minimum lease payments, undiscounted 161,008 379,000 Less: Imputed interest (15,646) (78,793) Present value of future minimum lease payments $ 145,362 $ 300,207

The following table sets forth the estimated amortization expense on intangible assets for the periods presented: Estimated amortization expense Year Ending December 31, 2025 $270,357 Year Ending December 31, 2026 219,228 Year Ending December 31, 2027 173,589 Year Ending December 31, 2028 130,285 Year Ending December 31, 2029 87,387 Goodwill and the value of indefinite-lived cable franchise rights acquired in business combinations are not amortized. Rather, such assets are tested for impairment annually as of October 1, or whenever events or changes in circumstances indicate that it is more likely than not that the assets may be impaired. See Note 2 for additional information. The carrying amount of indefinite-lived cable franchise rights and goodwill is presented below: Indefinite-lived Cable Franchise Rights Goodwill Balance as of December 31, 2022 $ 13,216,355 $ 8,208,773 Adjustment related to 2022 acquisition — (1,002) Goodwill impairment — (163,055) Balance as of December 31, 2023 13,216,355 8,044,716 Adjustment related to the sale of certain cable assets (5,047) (3,499) Balance as of December 31, 2024 $ 13,211,308 $ 8,041,217 Impairment Tests We assess the recoverability of our goodwill annually as of October 1 ("annual impairment test date"). Based on the quantitative impairment test for our reporting units performed in 2023, the estimated fair value of our Telecommunications reporting unit exceeded its carrying value and no impairment was recorded. However, the carrying value of our News and Advertising reporting unit exceeded its fair value resulting in an impairment charge of $163,055, representing the full carrying amount of the goodwill at the annual impairment test date. Approximately $130,040 of the goodwill was recorded in connection with the acquisition of Cheddar Inc. in 2019. The decrease in the fair value of the News and Advertising reporting unit was primarily due to a decrease in projected cash flows due to the overall decline in the advertising market and an increase in the discount rate used in the discounted cash flow method. No goodwill impairment charges were recognized in 2024. In our 2024 impairment test for our indefinite-lived cable franchise rights, the fair value (estimated using the multi-period excess earnings model) exceeded their carrying value, with no impairment recorded. Although no impairment was recognized, our fair value estimation relies on certain assumptions like revenue growth rates, long-term growth rates, and discount rates, which are subjective and involve significant judgment. Changes in these assumptions could impact the estimates. For example, if our financial performance deteriorates, or if interest rates increase, it is reasonably possible that a future impairment of our franchise assets could be material. A hypothetical 10% reduction in the fair value of our franchise rights would result in an impairment charge of approximately $1,200,000.

(e) Pursuant to the loan agreement, interest will be calculated for any (i) SOFR loan, at a rate per annum equal to the Term SOFR (plus spread adjustments of 0.11448%, 0.26161% and 0.42826% for interest periods of one, three and six months, respectively) or (ii) the alternate base rate loan, at the alternative base rate as applicable, plus the applicable margin in each case, where the applicable margin is 2.25% per annum with respect to any alternate base rate loan and 3.25% per annum with respect to any SOFR loan (see Note 20). (f) The Term Loan B and Incremental Term Loan B-3 were repaid with proceeds from the issuance of senior guaranteed notes in January 2024. See discussion below. (g) The 5.250% senior notes were redeemed in February 2024 with proceeds from drawings under the CSC Holdings Revolving Credit Facility. See discussion below. (h) Excludes the amount of the note payable to Captive at CSC Holdings as it is eliminated in the Altice USA consolidated financial statements (see Note 16). For financing purposes, we have two debt silos: CSC Holdings and Lightpath. The CSC Holdings silo is structured as a restricted group (the "CSC Holdings Restricted Group") and an unrestricted group, which includes certain designated subsidiaries and investments. The CSC Holdings Restricted Group is comprised of CSC Holdings and substantially all of its wholly-owned operating subsidiaries excluding Cablevision Lightpath which became an unrestricted subsidiary in September 2020. These CSC Holdings Restricted Group subsidiaries are subject to the covenants and restrictions of the credit facility and indentures governing the notes issued by CSC Holdings. The Lightpath silo includes all of its operating subsidiaries which are subject to the covenants and restrictions of the credit facility and indentures governing the notes issued by Lightpath. See discussion below regarding the Lightpath debt financing. CSC Holdings Credit Facilities In October 2015, a wholly-owned subsidiary of Altice USA, which merged with and into CSC Holdings on June 21, 2016, entered into a senior secured credit facility, which, as amended, currently provides for U.S. dollar term loans (the "CSC Term Loans") and U.S. dollar revolving loan commitments (the "CSC Revolving Credit Facility" and, together with the CSC Term Loans, the "CSC Credit Facilities"), which are governed by a credit facilities agreement entered into by, inter alios, CSC Holdings, certain lenders party thereto and JPMorgan Chase Bank, N.A. as administrative agent and security agent (as amended, restated, supplemented or otherwise modified from time to time, the "CSC Credit Facilities Agreement"). Amounts outstanding under the CSC Holdings Credit Facilities bear interest, at our election, at Term SOFR, Synthetic USD LIBOR, or at an alternate base rate, as defined therein, plus an applicable margin. During the year ended December 31, 2024, CSC Holdings borrowed $2,025,000 under its revolving credit facility and repaid $1,150,000 of amounts outstanding under the revolving credit facility. The CSC Credit Facilities Agreement requires the prepayment of outstanding CSC Term Loans, subject to certain exceptions and deductions, with (i) 100% of the net cash proceeds of certain asset sales, subject to reinvestment rights and certain other exceptions; and (ii) on a pari ratable share (based on the outstanding principal amount of the CSC Term Loans divided by the sum of the outstanding principal amount of all pari passu indebtedness and the CSC Term Loans) of 50% of annual excess cash flow, which will be reduced to 0% if the consolidated net senior secured leverage ratio of CSC Holdings is less than or equal to 4.5 to 1. The obligations under the CSC Credit Facilities are guaranteed on a senior basis by each restricted subsidiary of CSC Holdings (other than CSC TKR, LLC and its subsidiaries, Lightpath, and certain excluded subsidiaries) and, subject to certain limitations, will be guaranteed by each future material wholly-owned restricted subsidiary of CSC Holdings. The obligations under the CSC Credit Facilities (including any guarantees thereof) are secured on a first priority basis, subject to any liens permitted by the CSC Credit Facilities, by capital stock held by CSC Holdings or any guarantor in certain subsidiaries of CSC Holdings, subject to certain exclusions and limitations. The CSC Credit Facilities Agreement includes certain negative covenants which, among other things and subject to certain significant exceptions and qualifications, limit CSC Holdings' ability and the ability of its restricted subsidiaries to: (i) incur or guarantee additional indebtedness, (ii) make investments, (iii) create liens, (iv) sell assets and subsidiary stock, (v) pay dividends or make other distributions or repurchase or redeem our capital stock or subordinated debt, (vi) engage in certain transactions with affiliates, (vii) enter into agreements that restrict the payment of dividends by subsidiaries or the repayment of intercompany loans and advances; and (viii) engage in mergers or consolidations. In addition, the CSC Revolving Credit Facility includes a financial maintenance covenant solely for the benefit of the lenders under the CSC Revolving Credit Facility consisting of a maximum consolidated net senior secured leverage ratio of CSC Holdings and its restricted subsidiaries of 5.0 to 1.0. The financial covenant is tested on the last day of any fiscal quarter, but only if on such day there are outstanding borrowings, as defined, under the CSC Revolving Credit Facility. The CSC Credit Facilities Agreement also contains certain customary representations and warranties, affirmative covenants and events of default (including, among others, an event of default upon a change of control). If an event of default occurs, the lenders under the CSC Credit Facilities will be entitled to take various actions, including the acceleration of amounts due under the CSC Credit Facilities and all actions permitted to be taken by a secured creditor. CSC Holdings Senior Guaranteed Notes and Senior Notes In January 2024, CSC Holdings issued $2,050,000 in aggregate principal amount of senior guaranteed notes due 2029. These notes bear interest at a rate of 11.750% and will mature on January 31, 2029. The proceeds from the sale of these notes were used to (i) repay the outstanding principal balance of the Term Loan B, (ii) repay the outstanding principal balance of the Incremental Term Loan B-3, and (iii) pay the fees, costs and expenses associated with these transactions. In connection with these transactions, we recorded a write-off of the outstanding deferred financing costs on these loans of $2,598. In February 2024, we redeemed the CSC Holdings 5.250% Senior Notes and 5.250% Series B Senior Notes due June 2024 with proceeds under the CSC Holdings Revolving Credit Facility. In connection with these transactions, we recorded a write-off of the outstanding deferred financing costs on these notes of $4,437. In April 2023, CSC Holdings issued $1,000,000 in aggregate principal amount of senior guaranteed notes that bear interest at a rate of 11.250% and mature on May 15, 2028. We used the proceeds to repay outstanding borrowings drawn under the Revolving Credit Facility. The indentures under which the Senior Guaranteed Notes and Senior Notes were issued contain certain customary covenants and agreements, including limitations on the ability of CSC Holdings and its restricted subsidiaries to (i) incur or guarantee additional indebtedness, (ii) make investments or other restricted payments, (iii) create liens, (iv) sell assets and subsidiary stock, (v) pay dividends or make other distributions or repurchase or redeem our capital stock or subordinated debt, (vi) engage in certain transactions with affiliates, (vii) enter into agreements that restrict the payment of dividends by subsidiaries or the repayment of intercompany loans and advances, and (viii) engage in mergers or consolidations, in each case subject to certain exceptions. The indentures also contain certain customary events of default. If an event of default occurs, the obligations under the notes may be accelerated. Subject to customary conditions, we may redeem some or all of the notes at the redemption price set forth in the relevant indenture, plus accrued and unpaid interest, plus a specified "make-whole" premium (in the event the notes are redeemed prior to a certain specified time set forth in the indentures). Lightpath Credit Facility On September 29, 2020, Lightpath entered into a credit agreement between, inter alios, certain lenders party thereto and Goldman Sachs Bank USA, as administrative agent, and Deutsche Bank Trust Company Americas, as collateral agent, (the "Lightpath Credit Agreement") which initially provided for, among other things, (i) a term loan in an aggregate principal amount of $600,000 (the “Lightpath Term Loan Facility”) at a price of 99.50% of the aggregate principal amount, which was drawn on November 30, 2020, and (ii) revolving loan commitments in an aggregate principal amount of $100,000 (the “Lightpath Revolving Credit Facility"). During the year ended December 31, 2024, Lightpath borrowed and repaid $40,000 under its revolving credit facility. As of December 31, 2024 and 2023, there were no borrowings outstanding under the Lightpath Revolving Credit Facility. In June 2023, Lightpath entered into an amendment (the "First Amendment") under its existing credit agreement to replace LIBOR-based benchmark rates with SOFR-based benchmark rates. The First Amendment provides for interest on borrowings under its term loan and revolving credit facility to be calculated for any (i) SOFR loan, at a rate per annum equal to the Term SOFR (plus spread adjustments of 0.11448%, 0.26161% and 0.42826% for interest periods of one, three and six months, respectively) or (ii) the alternate base rate loan, at the alternative base rate as applicable, plus the applicable margin in each case, where the applicable margin is 2.25% per annum with respect to any alternate base rate loan and 3.25% per annum with respect to any SOFR loan. In February 2024, Lightpath entered into an extension amendment (the "Extension Amendment") to its amended credit agreement that provides for, among other things, (a) an extension of the scheduled maturity date with respect to the 2027 Revolving Credit Commitments (as defined in the Extension Amendment) under the credit agreement to the date (the "New Maturity Date") that is the later of (x) November 30, 2025 and (y) the earlier of (i) June 15, 2027 and (ii) the date that is five business days after any Extension Breach Date (as defined in the Amended Credit Agreement) and (b) incremental revolving credit commitments in an aggregate principal amount of $15,000 which shall be of the same class and type as the 2027 Revolving Credit Commitments and will, for the avoidance of doubt, mature on the New Maturity Date. After giving effect to the Extension Amendment, the aggregate principal amount of revolving loan commitments available under the Lightpath Credit Agreement, as amended, equaled $115,000. After giving effect to the Extension Amendment, the aggregate principal amount of 2027 Revolving Credit Commitments equaled $95,000 and the aggregate principal amount of 2025 Revolving Credit Commitments (as defined in the Extension Amendment) equaled $20,000. Interest will be calculated at a rate per annum equal to the adjusted Term SOFR rate or the alternate base rate, as applicable, plus the applicable margin, where the applicable margin is (i) with respect to any alternate base rate loan, 2.25% per annum and (ii) with respect to any Term SOFR loan, 3.25% per annum. In November 2024, Lightpath entered into an incremental amendment (the "Incremental Amendment") to its amended credit agreement to incur an additional $100,000 of term loan under the Lightpath Term Loan Facility (the "Incremental Term Loans"), at a net price of 99.27%, which increased the aggregate principal amount of term loan outstanding under the Lightpath Term Loan Facility to $676,000 as of December 31, 2024. A portion of the net proceeds from the Incremental Term Loans were used to fund an acquisition of a fiber network and the balance was used for general corporate purposes. We are required to make scheduled quarterly payments of $1,760 pursuant to the Lightpath Term Loan Facility. Debt issued by Lightpath is subject to certain restrictive covenants. Lightpath is subject to incurrence based covenants, which do not require ongoing compliance with financial ratios, but place certain limitations on the Lightpath's ability to, among other things, incur or guarantee additional debt (including to finance new acquisitions), create liens, pay dividends and other distributions or prepay subordinated indebtedness, make investments, sell assets, engage in affiliate transactions or engage in mergers or consolidations. Additionally, if borrowings under the Lightpath Revolving Credit Facility exceed a certain threshold, Lightpath and its subsidiaries are also subject to a springing financial maintenance covenant in the Lightpath Credit Agreement requiring ongoing compliance with a net senior secured leverage ratio of no greater than 7.30:1. These covenants are subject to several important exceptions and qualifications. To be able to incur additional debt under an applicable debt instrument, Lightpath must either meet the ratio test described below (on a pro forma basis for any contemplated transaction giving rise to the debt incurrence) or have available capacity under the general debt basket or meet certain other exceptions to the limitation on indebtedness covenant in such debt instrument. Senior debt of Lightpath will be subject to an incurrence test of 6.75:1 (Consolidated Net Leverage to L2QA Pro Forma EBITDA (each as defined in the relevant debt instruments)) and senior secured debt of Lightpath will be subject to an incurrence test of 4.75:1 (Consolidated Net Senior Secured Leverage (as defined in the relevant debt instrument) to L2QA Pro Forma EBITDA). Debt Compliance As of December 31, 2024, CSC Holdings and Lightpath were in compliance with applicable financial covenants under their respective credit facilities and with applicable financial covenants under each respective indenture by which the senior guaranteed notes, senior secured notes and senior notes were issued. Gain (Loss) on Extinguishment of Debt and the Write-off of Deferred Financing Costs The following table provides a summary of the gain (loss) on extinguishment of debt and the write-off of deferred financing costs recorded: For the Year Ended December 31, 2024 2023 2022 Settlement of collateralized debt (see Note 12) $ — $ 4,393 $ — Incremental borrowing under the Lightpath Term Loan Facility (5,866) — — Repayment of CSC Holdings Term Loan B and Incremental Term Loan B-3 (2,598) — — Redemption of 5.250% Senior Notes and 5.250% Series B Senior Notes due June 2024 (4,437) — — Refinancing of CSC Holdings Term Loan B and Incremental Term Loan B-3 — — (575) $ (12,901) $ 4,393 $ (575) Supply Chain Financing Arrangement We have a supply chain financing arrangement with a financial institution with credit availability of $175,000 that is used to finance certain of our property and equipment purchases. This arrangement extends our repayment terms beyond a vendor’s original invoice due dates (for up to one year) and as such are classified as debt on our consolidated balance sheets. The following is a rollforward of the outstanding balances relating to our supply chain financing arrangement: Balance as of December 31, 2022 $ 123,880 Invoices financed 213,325 Repayments (162,751) Balance as of December 31, 2023 174,454 Invoices financed 50,642 Repayments (174,454) Balance as of December 31, 2024 $ 50,642 Summary of Debt Maturities The future principal payments under our various debt obligations outstanding as of December 31, 2024, including supply chain financing, but excluding finance lease obligations (see Note 9), are as follows: Years Ending December 31, 2025 $ 107,703 2026 57,061 2027 6,939,436 2028 (a) 5,371,850 2029 3,800,000 Thereafter 8,675,000 (a) Includes $1,906,850 principal amount related to CSC Holdings' Incremental Term Loan B-6 that is due on the earlier of (i) January 15, 2028 and (ii) April 15, 2027 if, as of such date, any Incremental Term Loan B-5 borrowings are still outstanding, unless the Incremental Term Loan B-5 maturity date has been extended to a date falling after January 15, 2028.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS	DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS Prepaid Forward Contracts Historically, we had entered into various transactions to limit the exposure against equity price risk on shares of Comcast Corporation ("Comcast") common stock we previously owned. We monetized all of our stock holdings in Comcast through the execution of prepaid forward contracts, collateralized by an equivalent amount of the respective underlying stock. In January 2023, we settled our outstanding collateralized indebtedness by delivering the Comcast shares we held and the related equity derivative contracts which resulted in us receiving net cash of approximately $50,500 (including dividends of $11,598) and recorded a gain on the extinguishment of debt of $4,393. As of December 31, 2024 and 2023, we did not hold and have not issued equity derivative instruments for trading or speculative purposes. Interest Rate Swap Contracts To manage interest rate risk, we have from time to time entered into interest rate swap contracts to adjust the proportion of total debt that is subject to variable and fixed interest rates. Such contracts effectively fix the borrowing rates on floating rate debt to provide an economic hedge against the risk of rising rates and/or effectively convert fixed rate borrowings to variable rates to permit us to realize lower interest expense in a declining interest rate environment. We monitor the financial institutions that are counterparties to our interest rate swap contracts and we only enter into interest rate swap contracts with financial institutions that are rated investment grade. All such contracts are not designated as hedges for accounting purposes and are carried at their fair market values on our consolidated balance sheets, with changes in fair value reflected in the consolidated statements of operations. In September 2024, we terminated all our CSC Holdings interest rate swap agreements with an aggregate notional value of $3,000,000. These contracts were due to mature in January 2025 and December 2026. In connection with these early terminations, we received cash of $43,182 presented in operating activities in our consolidated statements of cash flows and incurred a loss of $52,943 which is included in the net gain on interest rate swap contracts reflected in our consolidated statements of operations. In November 2024, Lightpath entered into an interest rate swap contract on a notional amount of $95,000, whereby Lightpath pays interest of 3.979% and it receives interest based on one-month SOFR through December 2026.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels: • Level I - Quoted prices for identical instruments in active markets. • Level II - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level III - Instruments whose significant value drivers are unobservable. The following table presents our financial assets and financial liabilities that are measured at fair value on a recurring basis and their classification under the fair value hierarchy: Fair Value December 31, 2024 2023 Assets: Money market funds (a) Level I $ 158,648 $ 49,541 Interest rate swap contracts Level II 8,466 112,914 Liabilities: Contingent consideration related to acquisitions Level III 6,974 2,037 (a) Money market funds at CSC Holdings amounted to $151,205 and $49,541 as of December 31, 2024 and 2023, respectively. Our money market funds which are classified as cash equivalents are classified within Level I of the fair value hierarchy because they are valued using quoted market prices. The interest rate swap contracts on our consolidated balance sheets are valued using market-based inputs to valuation models. These valuation models require a variety of inputs, including contractual terms, market prices, yield curves, and measures of volatility. When appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads and credit risk considerations. Such adjustments are generally based on available market evidence. Since model inputs can generally be verified and do not involve significant management judgment, we have concluded that these instruments should be classified within Level II of the fair value hierarchy. The fair value of the contingent consideration as of December 31, 2024 and 2023 related to certain acquisitions was determined using a probability assessment of the contingent payment for the respective periods. Fair Value of Financial Instruments The following methods and assumptions were used to estimate fair value of each class of financial instruments for which it is practicable to estimate: Credit Facility Debt, Senior Notes, Senior Guaranteed Notes, Senior Secured Notes, Notes Payable, and Supply Chain Financing The fair values of each of our debt instruments are based on quoted market prices of these instruments. The carrying value of outstanding amounts related to supply chain financing agreements approximates the fair value due to their short-term maturity (less than one year). The carrying value of outstanding amounts related to notes payable as of December 31, 2023 approximated fair value due to their short-term maturity (also less than one year). The carrying values, estimated fair values, and classification under the fair value hierarchy of our financial instruments, excluding those that are carried at fair value in the accompanying consolidated balance sheets, are summarized below: December 31, 2024 December 31, 2023 Fair Value Carrying Estimated Carrying Estimated Credit facility debt Level II $ 7,156,989 $ 7,200,408 $ 8,257,682 $ 8,323,654 Senior guaranteed and senior secured notes Level II 11,119,314 9,503,825 9,079,882 7,784,288 Senior notes Level II 6,585,181 3,825,788 7,334,447 4,932,931 Notes payable and supply chain financing (b) Level II 50,642 50,642 174,594 174,594 $ 24,912,126 $ 20,580,663 $ 24,846,605 $ 21,215,467 (a) Amounts are net of unamortized deferred financing costs and discounts/premiums.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Altice USA files a federal consolidated and certain state combined income tax returns with its 80% or more owned subsidiaries. CSC Holdings and its subsidiaries are included in the consolidated federal income tax returns of Altice USA. The income tax provision for CSC Holdings is determined on a stand-alone basis for all periods presented as if CSC Holdings filed separate consolidated income tax returns. In accordance with a tax sharing agreement between CSC Holdings and Altice USA, CSC Holdings has an obligation to Altice USA for its stand-alone current tax liability as if it filed separate income tax returns. Income tax expense for the years ended December 31, 2024, 2023 and 2022 consist of the following components: Altice USA CSC Holdings Years Ended December 31, Years Ended December 31, 2024 2023 2022 2024 2023 2022 Current expense (benefit): Federal $ 312,330 $ 227,189 $ 133,329 $ 311,628 $ 227,189 $ 133,329 State 6,626 54,130 81,076 6,626 62,312 88,068 Foreign — 105 128 — 105 128 318,956 281,424 214,533 318,254 289,606 221,525 Deferred expense (benefit): Federal (321,244) (210,378) (43,797) (321,245) (210,378) (43,797) State (74,872) (16,547) 80,356 (78,370) (21,680) 69,676 Foreign 64 10 (174) 64 10 (174) (396,052) (226,915) 36,385 (399,551) (232,048) 25,705 (77,096) 54,509 250,918 (81,297) 57,558 247,230 Tax expense (benefit) relating to uncertain tax positions 73,025 (14,981) 44,922 73,025 (14,981) 44,922 Income tax expense (benefit) $ (4,071) $ 39,528 $ 295,840 $ (8,272) $ 42,577 $ 292,152 The income tax expense (benefit) attributable to operations differs from the amount derived by applying the statutory federal rate to pretax income (loss) principally due to the effect of the following items: Altice USA CSC Holdings Years Ended December 31, Years Ended December 31, 2024 2023 2022 2024 2023 2022 Federal tax expense (benefit) at statutory rate $ (17,293) $ 24,899 $ 108,513 $ (17,995) $ 24,899 $ 108,513 State income taxes, net of federal impact (66,814) 6,436 26,527 (72,536) 9,842 28,768 Minority interest (5,662) (5,494) (5,914) (5,662) (5,494) (5,914) Changes in the valuation allowance 5,598 13,847 20,176 7,821 14,099 15,494 Change in New York state rate to measure deferred taxes, net of federal impact — — 112,117 — — 112,117 Other changes in the state rates used to measure deferred taxes, net of federal impact (5,350) 23,909 (9,603) (5,350) 23,300 (10,849) Tax expense (benefit) relating to uncertain tax positions 63,941 (14,311) 36,281 63,941 (14,311) 36,281 Tax credits (3,987) (4,201) (3,544) (3,987) (4,201) (3,544) Excess tax deficiencies related to share-based compensation including non-deductible carried unit plans 12,353 11,696 10,321 12,353 11,696 10,321 Non-deductible officers compensation 3,027 3,934 4,916 3,027 3,934 4,916 Foreign losses of disregarded entities (8,361) (6,097) (6,352) (8,361) (6,097) (6,352) Business dispositions — (46,591) — — (46,591) — Goodwill impairment and other permanent differences 16,887 34,241 — 16,887 34,241 — Other, net 1,590 (2,740) 2,402 1,590 (2,740) 2,401 Income tax expense (benefit) $ (4,071) $ 39,528 $ 295,840 $ (8,272) $ 42,577 $ 292,152 We have decided to exit the commitment we made in May 2021 of investing $600,000 in capital gains generated from the 49.99% sale of Lightpath in 2020, into Qualified Opportunity Zones (“QOZ”) over the next 5 years, which allowed for tax deferral recognition until 2026. The tax expense impact of this exit is approximately $1,269 for the year ended December 31, 2024. Also during 2024, we increased our unrecognized tax benefit (“UTB”) reserve liability for tax years 2023 and 2024 relating to the qualified emerging technology company (“QETC”) position taken in 2022 described below, as well as for the state impact on the QOZ exit discussed above. Due to the sale of our Cheddar News business in December 2023 to an unrelated third party, we recognized a capital loss resulting in an income tax benefit for the year ended December 31, 2023. In addition, our income tax expense for the year ended December 31, 2023 was impacted by the non-deductibility of the impairment of goodwill related to our News and Advertising business (see Note 10). In December 2022, the New York State Division of Tax Appeals, via an Administrative Law Judge determination, published a decision in Charter Communications, Inc. versus New York State, which concluded that each corporation in a combined reporting group would have to separately qualify as a QETC to use the preferential QETC tax rate. As we had been historically using the QETC rate at the combined reporting group level, we recorded a cumulative income tax expense of $157,300 that included both a revaluation of state deferred taxes and an increase to our uncertain tax positions reserve for tax years 2017 through 2022 based on this published decision. The tax effects of temporary differences which give rise to significant portions of deferred tax assets or liabilities and the corresponding valuation allowance are as follows: Altice USA CSC Holdings December 31, December 31, 2024 2023 2024 2023 Noncurrent NOLs, capital loss, and tax credit carry forwards (a) $ 129,444 $ 130,134 $ 109,103 $ 104,071 Compensation and benefit plans 61,486 90,853 61,486 90,853 Restructuring liability 2,349 7,220 2,349 7,220 Other liabilities 21,482 50,440 21,482 50,440 Research and experimental expenditures 40,872 33,427 40,872 33,427 Interest deferred for tax purposes 781,826 536,284 781,826 536,284 Investments 1,516 1,519 1,516 1,519 Operating lease liability 74,773 79,263 74,773 79,263 Deferred tax assets 1,113,748 929,140 1,093,407 903,077 Less: Valuation allowance (93,005) (87,407) (72,664) (64,844) Net deferred tax assets, noncurrent 1,020,743 841,733 1,020,743 838,233 Deferred tax liabilities: Fixed assets and intangibles (5,208,559) (5,250,112) (5,208,559) (5,250,112) Operating lease asset (61,014) (64,163) (61,014) (64,163) Partnership investments (185,473) (173,198) (185,473) (173,198) Prepaid expenses (11,513) (14,630) (11,513) (14,630) Derivative contracts (9,745) (40,357) (9,745) (40,357) Fair value adjustments related to debt and deferred financing costs — (1,751) — (1,751) Opportunity Zone tax deferral — (145,655) — (145,655) Deferred tax liability, noncurrent (5,476,304) (5,689,866) (5,476,304) (5,689,866) Total net deferred tax liabilities $ (4,455,561) $ (4,848,133) $ (4,455,561) $ (4,851,633) (a) Includes deferred tax assets of $279 and $326 as of December 31, 2024 and 2023, respectively, that relate to the net operating losses of foreign subsidiaries which are presented under Other assets on the consolidated balance sheets. Due to the exit of the QOZ commitment in 2024 discussed above, taxes payable (recorded in other current liabilities) and the UTB reserve increased by $93,624 and $12,920, respectively, while the deferred tax liability decreased by $105,278, on our consolidated balance sheet at December 31, 2024. In the fourth quarter of 2024, we carried back the net capital loss of $98,207 due to the sale of the Cheddar News business in December 2023 against the taxable capital gain generated in connection with the 49.99% sale of Lightpath in 2020. Deferred tax assets have resulted primarily from our future deductible temporary differences and NOLs. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax asset will not be realized. In evaluating the need for a valuation allowance, management takes into account various factors, including the expected level of future taxable income, available tax planning strategies and reversals of existing taxable temporary differences. If such estimates and related assumptions change in the future, we may be required to record additional valuation allowances against its deferred tax assets, resulting in additional income tax expense in our consolidated statements of operations. Management evaluates the realizability of the deferred tax assets and the need for additional valuation allowances quarterly. Due to the significant deferred tax liabilities associated with our fixed assets and intangibles, primarily due to the change in the 2017 TCJA, allowing 100% bonus depreciation on most fixed assets (this percentage decreased to 60% for 2024), as well as the continued taxable income adjustments associated with the deferred tax liabilities established under purchase accounting pursuant to the Cablevision and Cequel acquisitions in 2016, the future taxable income that will result from the reversal of existing taxable temporary differences for which deferred tax liabilities are recognized is sufficient to conclude it is more likely than not that we will realize all of its gross deferred tax assets, except those deferred tax assets against which a valuation allowance has been recorded which relate to certain state NOLs and the foreign NOLs in i24NEWS. In the normal course of business, we engage in transactions in which the income tax consequences may be uncertain. Our income tax returns are filed based on interpretation of tax laws and regulations. Such income tax returns are subject to examination by taxing authorities. For financial statement purposes, we only recognize tax positions that it believes are more likely than not of being sustained. There is considerable judgment involved in determining whether positions taken or expected to be taken on the tax return are more likely than not of being sustained. Changes in the liabilities for uncertain tax positions are recognized in the interim period in which the positions are effectively settled or there is a change in factual circumstances. The following is the activity relating to our UTB reserve liability: Years Ended December 31, 2024 2023 2022 Balance at beginning of year $ 53,010 $ 70,593 $ 25,296 Increases (decreases) from prior period positions 46,762 (18,714) 871 Increases from current period positions 15,117 1,131 44,426 Decreases relating to settlements with tax authorities (524) — — Balance at end of year $ 114,365 $ 53,010 $ 70,593 Interest and penalties related to UTBs are included in our provision for income taxes. We recognized a net expense for interest and penalties of $17,862, $1,475, and $9,683 during the years ended December 31, 2024, 2023, and 2022, respectively. As of December 31, 2024 and 2023, accrued interest and penalties associated with UTBs were $36,126 and $18,264, respectively. The increase in interest and penalties for the year ended December 31, 2024 was primarily due to the interest accruals on our QETC and Investment Tax Credits positions. The increase in interest and penalties for the year ended December 31, 2023 was primarily due to an interest accrual on our QETC reserve position (see discussion above). We are not expecting a material change in this reserve due to expiring statutes, audit activity, or tax payments in the next twelve months. If we were to prevail on all uncertain positions, the net effect would result in an income tax benefit of $87,465.

SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION The following table presents share-based compensation expense (benefit) and unrecognized compensation cost: Share-Based Compensation Unrecognized Compensation Cost 2024 2023 2022 Awards issued pursuant to LTIP: Stock option awards (a) $ 997 $ (3,850) $ 86,307 $ 2,035 Performance stock units (a) (2,053) (12,757) 10,220 2,636 Restricted share units 47,222 33,809 63,458 41,870 Cash denominated performance awards 16,426 7,674 — 64,656 Other 4,570 23,050 — 611 $ 67,162 $ 47,926 $ 159,985 $ 111,808 (a) The benefit for the year ended December 31, 2024 reflects credits due to forfeitures. The benefit for the year ended December 31, 2023 includes credits due to the modification of awards to certain former executive officers and other forfeitures. Long Term Incentive Plan Pursuant to the Altice USA 2017 Long Term Incentive Plan, as amended (the "2017 LTIP"), we may grant awards of options, restricted shares, restricted share units, stock appreciation rights, performance stock, performance stock units and other awards. The maximum aggregate number of shares that may be issued for all purposes under the Plan is 89,879,291. Awards may be granted to our officers, employees and consultants or any of our affiliates. The 2017 LTIP is administered by Altice USA's Board of Directors (the "Board"), subject to the provision of the stockholders' agreement. The Board has delegated its authority to our Compensation Committee. The Compensation Committee has the full power and authority to, among other things, select eligible participants, to grant awards in accordance with the 2017 LTIP, to determine the number of shares subject to each award or the cash amount payable in connection with an award and determine the terms and conditions of each award. Stock Option Awards Options outstanding under the 2017 LTIP Plan either (i) cliff vest on the third anniversary of the date of grant, (ii) vest over 3 years in annual increments of 33-1/3%, or (iii) vest over 4 years, where 50% vest on the second anniversary, 25% on the third anniversary and 25% on the fourth anniversary of the date of grant. The option awards generally are subject to continued employment with the Company, and expire 10 years from the date of grant. Performance based option awards vest upon achievement of performance criteria. The following table summarizes activity related to stock options granted to our employees: Shares Under Option Weighted Average Weighted Average Remaining Time Aggregate Intrinsic Balance at December 31, 2021 50,998,816 $ 22.51 8.29 $ 6,801 Granted 7,888,472 9.30 Forfeited and Cancelled (7,811,613) 23.84 Balance at December 31, 2022 51,075,675 $ 20.27 7.73 $ 184 Granted 640 4.69 Forfeited (3,525,176) 21.94 Exchanged and Cancelled (b) (24,015,508) 20.72 Balance at December 31, 2023 23,535,631 $ 19.55 5.98 $ — Forfeited and Cancelled (6,293,905) 22.69 Balance at December 31, 2024 17,241,726 $ 18.40 5.72 $ — Options exercisable at December 31, 2024 15,406,617 $ 19.89 5.47 $ — (a) The aggregate intrinsic value is calculated as the difference between the exercise price and the closing price of Altice USA's Class A common stock at the respective date. (b) Options exchanged and cancelled in connection with our stock option exchange program discussed below. As of December 31, 2024, the total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of approximately 1.77 years. We calculate the fair value of each option award on the date of grant using the Black-Scholes valuation model. Our computation of expected life was determined based on the simplified method (the average of the vesting period and option term) due to our lack of recent historical data for similar awards. The interest rate for periods within the contractual life of the stock option was based on interest yields for U.S. Treasury instruments in effect at the time of grant. Our computation of expected volatility was based on historical volatility of the Altice USA common stock and the expected volatility of comparable publicly-traded companies who granted options that had similar expected lives. The weighted-average fair values of stock option awards granted during the years ended December 31, 2023 and 2022 were $2.42 and $3.76, respectively. The following weighted-average assumptions were used to calculate these fair values: Years Ended December 31, 2023 2022 Risk-free interest rate 3.53% 3.42% Expected life (in years) 5.71 6.24 Dividend yield —% —% Volatility 50.10% 41.79% In January 2023, we commenced a stock option exchange program (the "Exchange Offer") pursuant to which eligible employees were provided the opportunity to exchange eligible stock options for a number of restricted stock units (“RSU”) and deferred cash-denominated awards (“DCA”) at the exchange ratio of one RSU and $10 of DCAs for every seven eligible options tendered. In connection with the Exchange Offer, we canceled 24,015,508 options and granted 3,430,433 restricted stock units and $34,309 of DCAs awards. The exchange of these options was accounted for as a modification of share-based compensation awards. Accordingly, we will recognize the unamortized compensation cost related to the cancelled options of approximately $33,475, as well as the incremental compensation cost associated with the replacement awards of $34,000 over their two year vesting term. Performance Stock Units Certain of our employees were granted performance stock units ("PSUs"). Each PSU gives the employee the right to receive one share of Altice USA class A common stock, upon achievement of a specified stock price hurdle. The PSUs will be forfeited if the applicable performance measure is not achieved prior to January 29, 2026 or if the employee does not continue to provide services to the Company through the achievement date of the applicable performance measure. The following table summarizes activity related to PSUs granted to our employees: Number of Units Balance at December 31, 2021 6,361,894 Forfeited (1,182,535) Balance at December 31, 2022 5,179,359 Forfeited (1,411,606) Balance at December 31, 2023 3,767,753 Forfeited (1,044,201) Balance at December 31, 2024 2,723,552 The PSUs have a weighted average grant date fair value of $6.00 per unit as of December 31, 2024. The total unrecognized compensation cost related to outstanding PSUs is expected to be recognized over a weighted-average period of approximately 1.1 years. Restricted Share Units We granted restricted stock units ("RSUs") to certain employees pursuant to the 2017 LTIP. These awards vest either over three years in 33-1/3% annual increments or 4 years, where 50% vest on the second anniversary, 25% on the third anniversary and 25% on the fourth anniversary of the date of grant. The following table summarizes activity related to RSUs granted to our employees: Number of Units Weighted Average Grant Price Balance at December 31, 2021 6,617,837 $ 16.23 Granted 3,597,775 8.00 Vested (2,141,449) 15.99 Forfeited (578,775) 15.48 Balance at December 31, 2022 7,495,388 $ 12.41 Granted (including 3,430,433 in connection with Exchange Offer) 19,975,943 4.15 Vested (1,913,348) 10.20 Forfeited (3,064,095) 9.80 Balance at December 31, 2023 22,493,888 $ 4.93 Granted 21,314,660 2.51 Vested (8,427,473) 5.81 Forfeited (5,234,572) 3.87 Balance at December 31, 2024 30,146,503 $ 3.12 Cash Denominated Performance Awards The following table summarizes activity related to cash denominated performance awards granted to our employees: Number of Units Balance at December 31, 2022 — Granted 52,017,500 Forfeited (3,525,000) Balance at December 31, 2023 48,492,500 Granted 56,142,500 Forfeited (12,288,750) Balance at December 31, 2024 92,346,250 The cash denominated performance awards cliff vest in three years. The payout of these awards can range from 0% to 200% of the target value based on our achievement of certain revenue and Adjusted EBITDA targets during a three year performance period. These awards will be settled in shares of our Class A common stock, or cash, at our option. Lightpath Plan Awards Lightpath Management Incentive Aggregator LLC ("LMIA") has a Management Incentive Plan (the "Lightpath Plan") for the benefit of employees of Lightpath. The Lightpath Plan issues equity interests in LMIA which holds an equivalent number of equity interests in Lightpath Holdings LLC, the parent of Lightpath. These equity interests allow employees to participate in the long-term growth of Lightpath. The Lightpath Plan provides for an aggregate of 650,000 Class A-1 management incentive units and 350,000 Class A-2 management incentive units for issuance. As of December 31, 2024, 577,334 Class A-1 management incentive units and 280,905 Class A-2 management incentive units ("Award Units") granted to certain employees of Lightpath were outstanding. Vested units will be redeemed upon a partial exit, a change in control or the completion of an initial public offering, as defined in the Lightpath Holdings LLC agreement. The grant date fair value of the Award Units outstanding aggregated $31,504 and will be expensed in the period in which a partial exit or a liquidity event is consummated.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments Future cash payments and commitments required under arrangements pursuant to contracts entered into by us in the normal course of business as of December 31, 2024, are as follows: Payments Due by Period Total Year 1 Years 2-3 Years 4-5 More than Off balance sheet arrangements: Purchase obligations (a) $ 4,623,621 $ 2,302,722 $ 2,213,188 $ 102,067 $ 5,644 Guarantees (b) 70,756 70,751 — 5 — Letters of credit (c) 163,737 125 950 1,605 161,057 Total $ 4,858,114 $ 2,373,598 $ 2,214,138 $ 103,677 $ 166,701 (a) Purchase obligations primarily include contractual commitments with various programming vendors to provide video services to customers and minimum purchase obligations to purchase goods or services, including contracts to acquire handsets and other equipment. Future fees payable under contracts with programming vendors are based on numerous factors, including the number of customers receiving the programming. Amounts reflected above related to programming agreements are based on the number of customers receiving the programming as of December 31, 2024, multiplied by the per customer rates or the stated annual fee, as applicable, contained in the executed agreements in effect as of December 31, 2024. (b) Includes franchise and performance surety bonds primarily for our cable television systems. (c) Represent letters of credit guaranteeing performance to municipalities and public utilities and payment of insurance premiums. Payments due by period for these arrangements represent the year in which the commitment expires although payments under these arrangements are required only in the event of nonperformance. The table above does not include obligations for payments required to be made under multi-year franchise agreements based on a percentage of revenues generated from video service per year. Many of our franchise agreements and utility pole leases require us to remove its cable wires and other equipment upon termination of the respective agreements. We have concluded that the fair value of these asset retirement obligations cannot be reasonably estimated since the range of potential settlement dates is not determinable. The table above does not include obligations for rent related to utility poles used in our operations. Our pole rental agreements are for varying terms, and management anticipates renewals as they expire. Rent expense incurred for pole rental attachments for the years ended December 31, 2024, 2023 and 2022 was $41,704, $40,868, and $40,277, respectively. Legal Matters On December 7, 2023, Warner Records Inc., Sony Music Publishing (US) LLC and a number of other purported copyright holders (collectively, the “Warner Plaintiffs”) filed a complaint in the U.S. District Court for the Eastern District of Texas (the “Warner Matter”), alleging that certain of our Internet subscribers directly infringed over 10,700 of the Warner Plaintiffs’ copyrighted works. The Warner Plaintiffs seek to hold us liable for claims of contributory infringement of copyright and vicarious copyright infringement. The Warner Plaintiffs also claim that our alleged secondary infringement was willful and seek substantial statutory damages. The parties currently are conducting fact discovery with summary judgment motions due in June 2025 and trial set for September 2025. We intend to and are vigorously defending against the claims in the Warner Matter. In addition to contesting the claims of liability, we have an affirmative defense under the Digital Millennium Copyright Act that, if successful, would preclude or limit monetary damages against us in connection with some or all of the Warner Plaintiffs’ asserted claims. There can be no assurance as to the outcome of this litigation. We may incur significant costs in defending this action, and if we need to take measures to reduce our exposure to these risks or are required to pay damages in relation to such claims or choose to settle such claims, our business, reputation, financial condition and results of operations could be materially adversely affected. On September 10, 2024, United States Technologies Communication Corp. d/b/a Netceed filed suit in the New York Supreme Court, New York County. Plaintiff asserts claims for declaratory judgment, breach of contract, and breach of the implied covenant of good faith and fair dealing for alleged violations of the parties’ services and sales agreements, and seeks compensatory damages, as set forth in the complaint. We deny the claims and intend to vigorously defend the lawsuit. On November 21, 2024, we filed a motion to dismiss in part plaintiff’s complaint. That motion remains pending. Although the outcome of this matter cannot be predicted and the impact of the final resolution on our results of operations in a subsequent reporting period is not known, management does not believe that the resolution of the matter will have a material adverse effect on our operations or financial position or our ability to meet our financial obligations as they become due. We also receive notices from third parties, and in some cases we are named as a defendant in lawsuits, claiming infringement of various patents or copyrights relating to various aspects of our businesses. In certain of these cases other industry participants are also defendants, and in certain of these cases we expect that some or all potential liability would be the responsibility of our vendors pursuant to applicable contractual indemnification provisions. In the event that we are found to infringe on any patent or other intellectual property rights, we may be subject to substantial damages or an injunction that could require us or our vendors to modify certain products and services we offer to our subscribers, as well as enter into royalty or license agreements with respect to the patents at issue. We are also party to various other lawsuits, disputes and investigations arising in the ordinary course of our business, some of which may involve claims for substantial damages, fines or penalties. Although the outcome of these matters cannot be predicted and the impact of the final resolution of these matters on our results of operations in a particular subsequent reporting period is not known, management does not believe that the resolution of these matters, individually, will have a material adverse effect on our operations or financial position or our ability to meet our financial obligations as they become due, but they could be material to our consolidated results of operations or cash flows for any one period.

Entity Information [Line Items]
Revenue Recognition	Revenue Recognition Residential Services We derive revenue through monthly charges to residential customers of our broadband, video, and telephony services, including installation services. In addition, we derive revenue from digital video recorder, video-on-demand, pay-per-view, and home shopping commissions which are reflected in "Residential video" revenues. We recognize broadband, video, and telephony revenues as the services are provided to a customer on a monthly basis. Each service is accounted for as a distinct performance obligation. Revenue from the sale of bundled services at a discounted rate is allocated to each product based on the standalone selling price of each performance obligation within the bundled offer. The standalone selling price requires judgment and is typically determined based on the current prices at which the separate services are sold by us. Installation revenue for our residential services is deferred and recognized over the benefit period, which is generally less than one year. The estimated benefit period takes into account both quantitative and qualitative factors including the significance of average installation fees to total recurring revenue per customer. Also, we offer mobile services providing data, talk and text to consumers in or near our service areas. Customers are billed monthly for access to and usage of our mobile services. We recognize mobile service revenue ratably over the monthly service period as the services are provided to the customers. We are assessed non-income related taxes by governmental authorities, including franchising authorities (generally under multi-year agreements), and collect such taxes from our customers. In instances where the tax is being assessed directly on us, amounts paid to the governmental authorities are recorded as programming and other direct costs and amounts received from the customers are recorded as revenue. For the years ended December 31, 2024, 2023 and 2022, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $212,207, $219,988 and $232,795, respectively. Business and Wholesale Revenue We derive revenue from the sale of products and services to both large enterprise and small and medium-sized business ("SMB") customers, including broadband, telephony, networking, video services and mobile reflected in "Business services and wholesale" revenues. Our business services also include ethernet, data transport, and IP-based virtual private networks. We provide managed services to businesses, including hosted telephony services (cloud based SIP-based private branch exchange), managed WiFi, managed desktop and server backup and managed collaboration services including audio and web conferencing. We also offer fiber-to-the-tower services to wireless carriers for cell tower backhaul, which enables wireline communications service providers to connect to customers that their own networks do not reach. We recognize revenues for these services as the services are provided to a customer on a monthly basis. Substantially all of our SMB customers are billed monthly and large enterprise customers are billed in accordance with the terms of their contracts which is typically on a monthly basis. Contracts with large enterprise customers typically range from three News and Advertising Revenue News and advertising revenue is primarily derived from the sale of (i) advertising inventory available on the programming carried on our cable television systems, as well as other systems (linear revenue), (ii) digital advertising, (iii) data analytics, and (iv) affiliation fees for news programming. As part of the agreements under which we acquire video programming, we typically receive an allocation of scheduled advertising time during such programming into which our cable systems can insert commercials. In several of the markets in which we operate, we have entered into agreements commonly referred to as interconnects with other cable operators to jointly sell local advertising. In some of these markets, we represent the advertising sales efforts of other cable operators; in other markets, other cable operators represent us. We also offer customers the opportunity to advertise on digital platforms. Advertising revenues are recognized when the advertising is distributed. For arrangements in which we control the sale of advertising and act as the principal to the transaction, we recognize revenue earned from the advertising customer on a gross basis and the amount remitted to the distributor as an operating expense. For arrangements in which we do not control the sale of advertising and act as an agent to the transaction, we recognize revenue net of any fee remitted to the distributor. Revenue earned from the data-driven, audience-based advertising solutions using advanced analytics tools is recognized when services are provided. Affiliation fee revenue derived by our news business is recognized as the programming services are provided. Other Revenue Other revenue includes revenue derived from the sale of mobile devices which is recognized upon delivery and acceptance of the equipment by the customer. Under our mobile device payment plan, the customer is sold the device in exchange for a non-interest-bearing installment note, which is repaid by the customer, typically over a 36-month term, and concurrently enters into a month-to-month contract for mobile service. We may offer certain promotions regarding mobile devices that provide billing credits applied over a specified term, contingent upon the customer maintaining service. These credits are included in the transaction price, which are allocated to the performance obligations based on their relative selling price and are recognized when earned. Revenues derived from other sources are recognized when services are provided or events occur. Customer Contract Costs Incremental costs incurred in obtaining a contract with a customer are deferred and recorded as an asset if the period of benefit is expected to be greater than one year. Sales commissions for enterprise customers are deferred and amortized over the average contract term. As the amortization period for sales commission expenses related to residential and SMB customers is less than one year, we utilize the practical expedient and are recognizing the costs when incurred. The costs of fulfilling a contract with a customer are deferred and recorded as an asset if they generate or enhance resources for us that will be used in satisfying future performance obligations and are expected to be recovered. Installation costs related to residential and SMB customers that are not capitalized as part of the initial deployment of new customer premise equipment are expensed as incurred pursuant to industry-specific guidance. Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheet and totaled $19,743 and $18,109 as of December 31, 2024 and 2023, respectively. A significant portion of our revenue is derived from residential and SMB customer contracts which are month-to month. As such, the amount of revenue related to unsatisfied performance obligations is not necessarily indicative of the future revenue to be recognized from our existing customer base. Contracts with enterprise customers generally range from three years to five years, and services may only be terminated in accordance with the contractual terms. Multiple-Element Transactions In the normal course of business, we may enter into multiple-element transactions where we are simultaneously both a customer and a vendor with the same counterparty or in which we purchase multiple products and/or services, or settle outstanding items contemporaneously with the purchase of a product or service, from a single counterparty. Our policy for accounting for each transaction negotiated contemporaneously is to record each deliverable of the transaction based on our best estimate of selling price in a manner consistent with that used to determine the price to sell each deliverable on a standalone basis. In determining the value of the respective deliverable, we utilize historical transactions, quoted market prices (as available), or comparable transactions.
Technical and Operating Expenses and Programming Costs	Programming and Other Direct Costs Costs of revenue related to delivery of services and goods are classified as "programming and other direct costs" in the accompanying consolidated statements of operations. Programming Costs Programming expenses related to our video service represent fees paid to programming distributors to license the programming distributed to video customers. This programming is acquired generally under multi-year distribution agreements, with rates usually based on the number of customers that receive the programming. If there are periods when an existing distribution agreement has expired and the parties have not finalized negotiations of either a renewal of that agreement or a new agreement for certain periods of time, we often continue to carry and pay for these services until execution of definitive replacement agreements or renewals. The amount of programming expense recorded during the interim period is based on our estimate of the ultimate contractual agreement expected to be reached, which is based on several factors, including previous contractual rates, customary rate increases and the current status of negotiations. Such estimates are adjusted as negotiations progress until new programming terms are finalized. In addition, we receive, or may receive, incentives from programming distributors for carriage of the distributors' programming. We generally recognize these incentives as a reduction of programming costs and are recorded in "programming and other direct costs", generally over the term of the distribution agreement.
Advertising Expenses	Advertising Expenses Advertising costs are charged to expense when incurred and are reflected in "other operating expenses" in the accompanying consolidated statements of operations. Advertising costs amounted to $263,529, $253,777 and $299,590 for the years ended December 31, 2024, 2023 and 2022, respectively.
Share-based Compensation	Share-Based Compensation Share-based compensation expense which primarily relates to awards of stock options, restricted shares, and performance stock units, is based on the fair value of share-based payment awards at the date of grant. We recognize share-based compensation expense over the requisite service period or when it is probable any related performance condition will be met. For awards with graded vesting, compensation cost is recognized on an accelerated method under the graded vesting method over the requisite service period. Share-based compensation expense related to awards that vest entirely at the end of the vesting period are expensed on a straight-line basis. We account for forfeitures as they occur.
Income Taxes	Income Taxes
Cash and Cash Equivalents	Cash and Cash Equivalents Our cash investments are placed with money market funds and financial institutions that are investment grade as rated by S&P Global Ratings and Moody's Investors Service. We select money market funds that predominantly invest in marketable, direct obligations issued or guaranteed by the United States government or its agencies, commercial paper, fully collateralized repurchase agreements, certificates of deposit, and time deposits. We consider the balance of our investment in funds that substantially hold securities that mature within three months or less from the date the fund purchases these securities to be cash equivalents. The carrying amount of cash and cash equivalents either approximates fair value due to the short-term maturity of these instruments or are at fair value.
Accounts Receivable	Accounts Receivable
Investments	Investment Securities
Long-Lived Assets and Amortizable Intangible Assets	Long-Lived Assets and Amortizable Intangible Assets
Internal Use Software	We capitalize certain internal and external costs incurred to acquire or develop internal-use software. Capitalized software costs are amortized over the estimated useful life of the software and reported in depreciation and amortization.
Amortizable Intangible Assets	Customer relationships, trade names and other intangibles established in connection with acquisitions that are finite-lived are amortized in a manner that reflects the pattern in which the projected net cash inflows are expected to occur, such as the sum of the years' digits method, or when such pattern does not exist, using the straight-line method over their respective estimated useful lives.
Asset Impairment	We review our long-lived assets (property, plant and equipment, and intangible assets subject to amortization) for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets Goodwill and the value of indefinite-lived cable franchise rights acquired in business combinations are not amortized. Rather, such assets are tested for impairment annually or whenever events or changes in circumstances indicate that it is more likely than not that the assets may be impaired. The assessment of recoverability may first consider qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit or the indefinite-lived cable franchise right is less than its carrying amount. These qualitative factors include macroeconomic conditions such as changes in interest rates, industry and market considerations, recent and projected financial performance of the reporting units, as well as other factors. A quantitative test is performed if we conclude that it is more likely than not that the fair value of a reporting unit or an indefinite-lived cable franchise right is less than its carrying amount or if a qualitative assessment is not performed. In 2024, we performed quantitative assessments for our goodwill and our indefinite-lived cable franchise rights recoverability tests. In 2023, we performed a quantitative assessment for our goodwill recoverability test and a qualitative assessment for our indefinite-lived cable franchise rights recoverability test. See Note 10 for a discussion of the results of our annual impairment tests. Goodwill Goodwill resulted from business combinations and represents the excess amount of the consideration paid over the identifiable assets and liabilities recorded in the acquisition. We test goodwill for impairment at the reporting unit level: (i) Telecommunications and (ii) News and Advertising. The quantitative test for goodwill identifies potential impairment by comparing the fair value of the reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. We estimate the fair value of our reporting units by considering both (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which is based on the expected normalized cash flows of the reporting units following the discrete projection period, and (ii) a market approach, which includes the use of multiples of publicly-traded companies whose services are comparable to ours. Significant judgments in estimating the fair value of our reporting units include cash flow projections and the selection of the discount rate. The estimates and assumptions utilized in estimating the fair value of our reporting units could have a significant impact on whether an impairment charge is recognized and also the magnitude of any such charge. Fair value estimates are made at a specific point in time, based on relevant information. These estimates are subjective in nature and involve uncertainties and matters of significant judgments. Changes in assumptions could significantly affect the estimates. Indefinite-lived Cable Franchise Rights Our indefinite-lived cable franchise rights reflect the value of agreements we have with state and local governments that allow us to construct and operate a cable business within a specified geographic area and allow us to solicit and service potential customers in the service areas defined by the franchise rights currently held by us. We have concluded that our cable franchise rights have an indefinite useful life since there are no legal, regulatory, contractual, competitive, economic or other factors that limit the period over which these rights will contribute to our cash flows. For impairment testing purposes, we have concluded that our cable franchise rights are a single unit of account.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs, which are presented as a reduction of debt, are amortized to interest expense using the effective interest method over the terms of the related debt.
Derivative Financial Instruments	Derivative Financial Instruments
Commitments and Contingencies	Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when we believe it is probable that a liability has been incurred and the amount of the contingency can be reasonably estimated.

Dividends and Distributions	Dividends and Distributions Altice USA Altice USA may pay dividends on its capital stock only from net profits and surplus as determined under Delaware law. If dividends are paid on the Altice USA common stock, holders of the Altice USA Class A common stock and Altice USA Class B common stock are entitled to receive dividends, and other distributions in cash, stock or property, equally on a per share basis, except that stock dividends with respect to Altice USA Class A common stock may be paid only with shares of Altice USA Class A common stock and stock dividends with respect to Altice USA Class B common stock may be paid only with shares of Altice USA Class B common stock. Our indentures restrict the amount of dividends and distributions in respect of any equity interest that can be made. During 2024, 2023 and 2022, there were no dividends paid to shareholders by Altice USA. CSC Holdings CSC Holdings may make distributions on its membership interests only if sufficient funds exist as determined under Delaware law. See Note 16 for a discussion of equity distributions that CSC Holdings made to its parent.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that may potentially subject us to a concentration of credit risk consist primarily of cash and cash equivalents and trade account receivables. We monitor the financial institutions and money market funds where it invests its cash and cash equivalents with diversification among counterparties to mitigate exposure to any single financial institution. Our emphasis is primarily on safety of principal and liquidity and secondarily on maximizing the yield on its investments. Management believes that no significant concentration of credit risk exists with respect to its cash and cash equivalents because of its assessment of the creditworthiness and financial viability of the respective financial institutions. We did not have a single customer that represented 10% or more of our consolidated revenues for the years ended December 31, 2024, 2023 and 2022 or 10% or more of our consolidated net trade receivables at December 31, 2024, and 2023, respectively.
Use of Estimates in Preparation of Financial Statements	Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See Note 13 for a discussion of fair value estimates.

Accounting Policies [Abstract]
Recently Adopted Accounting Pronouncements and Recently Issued But Not Yet Adopted Accounting Pronouncements	ACCOUNTING STANDARDS Accounting Standards Adopted in 2024 ASU No. 2023-07 Segment Reporting—Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting—Improvements to Reportable Segment Disclosures, to improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities. ASU No. 2023-07 is meant to enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, and provide new segment disclosure requirements for entities with a single reportable segment. We adopted ASU 2023-07 for the year ended December 31, 2024. See Note 18 for further information. Accounting Standards Adopted in 2023 ASU No. 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations In September 2022, the FASB issued ASU 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, to enhance transparency about an entity’s use of supplier finance programs. ASU 2022-04 requires the buyer in a supplier finance program to disclose (a) information about the key terms of the program, (b) the amount outstanding that remains unpaid by the buyer as of the end of the period, (c) a rollforward of such amounts during each annual period, and (d) a description of where in the financial statements outstanding amounts are being presented. We adopted ASU 2022-04 on January 1, 2023. See Note 11 for further information. Recently Issued But Not Yet Adopted Accounting Pronouncements ASU No. 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures In November 2024, the FASB issued ASU No. 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures , which requires disaggregated disclosures of certain categories of expenses on an annual and interim basis. ASU 2024-03 becomes effective for annual reporting periods beginning after December 15, 2026 (January 1, 2027 for us), and interim reporting periods beginning after December 15, 2027 (January 1, 2028 for us). We are currently evaluating the impact of adopting ASU 2024-03 on our consolidated financial statements and related disclosures, but we expect the adoption will result in additional disaggregation of expense captions within our footnote disclosures. ASU No. 2023-09 Income Taxes—Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU No. 2023-09, Income Taxes—Improvements to Income Tax Disclosures , which require greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid. ASU No. 2023-09 is effective for us for the year ending December 31, 2025, although early adoption is permitted. We are currently evaluating the impact of adopting ASU No. 2023-09, but we expect additional disclosure disaggregation in our income tax footnote.
