Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, these financial statements do not include all the information and notes required for complete annual financial statements. The interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. The financial statements presented in this report are unaudited; however, in the opinion of management, such financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the results for the periods presented. The results of operations for the interim periods are not necessarily indicative of the results that might be expected for future interim periods or for the full year ending December 31, 2024. The preparation of financial statements in conformity with 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 11 for a discussion of fair value estimates.

Earnings Per Share [Abstract]
NET INCOME (LOSS) 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 stock 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 (loss) per share attributable to Altice USA stockholders: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 (in thousands) Basic weighted average shares outstanding 460,626 454,730 459,335 454,702 Effect of dilution: Restricted stock — 55 — 99 Deferred cash-denominated awards — 291 — 317 Diluted weighted average shares outstanding 460,626 455,076 459,335 455,118 Weighted average shares excluded from diluted weighted average shares outstanding: Anti-dilutive shares 20,823 44,788 32,955 46,228 Share-based compensation awards whose performance metrics have not been achieved 25,172 25,947 21,554 19,230 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.

(c) Incremental Term Loan B-5 requires quarterly installments of $7,500 and bears interest at a rate equal to Synthetic USD London Interbank Offered Rate ("LIBOR") plus 2.50% per annum through March 31, 2025. Thereafter, we will be required to pay interest at a rate equal to the alternate base rate (“ABR”), plus the applicable margin, where the ABR is the greater of (x) prime rate or (y) the federal funds effective rate plus 50 basis points and the applicable margin for any ABR loan is 1.50% per annum. (d) Incremental Term Loan B-6 requires quarterly installments of $5,005 and bears interest at a rate equal to SOFR plus 4.50% per annum. (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. (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. 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. CSC Holdings Revolving Credit Facility During the nine months ended September 30, 2024, CSC Holdings borrowed $1,825,000 under its revolving credit facility and repaid $950,000 of amounts outstanding under the revolving credit facility. 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. Lightpath Credit Facility In February 2024, Lightpath entered into an extension amendment (the "Extension Amendment") to its amended credit agreement (the "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 Amended Credit Agreement equaled $115,000. Under 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. Debt Compliance As of September 30, 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. 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, 2023 $ 174,454 Purchases financed 50,642 Repayments (96,401) Balance as of September 30, 2024 $ 128,695 Summary of Debt Maturities The future principal payments under our various debt obligations outstanding as of September 30, 2024, including notes payable and supply chain financing, but excluding finance lease obligations, are as follows: 2024 $ 92,058 2025 106,662 2026 56,019 2027 6,841,519 2028 (a) 5,371,850 Thereafter 12,475,000 (a) Includes $1,906,850 principal amount related to the 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 September 30, 2024, 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 reflected in our consolidated statements of operations. The following represents the location of the assets associated with our derivative instruments within the consolidated balance sheets: Derivatives Not Designated as Hedging Instruments Balance Sheet Location Fair Value at September 30, 2024 December 31, 2023 Asset Derivatives: Interest rate swap contracts Other assets, long-term $ 4,691 $ 112,914 Liability Derivatives: Interest rate swap contracts Other liabilities, long-term $ (1,907) $ — The following table presents certain consolidated statement of operations data related to our derivative contracts and the underlying Comcast common stock: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Loss on derivative contracts related to change in the value of equity derivative contracts related to Comcast common stock $ — $ — $ — $ (166,489) Change in the fair value of Comcast common stock included in gain on investments — — — 192,010 Gain (loss) on interest rate swap contracts, net (45,657) 31,972 10,220 78,708 Interest Rate Swap Contracts The following is a summary of the terms of our outstanding interest rate swap contracts at September 30, 2024: Maturity Date Notional Amount Company Pays Company Receives Lightpath: December 2026 $300,000 Fixed rate of 2.11% One-month SOFR December 2026 180,000 Fixed rate of 3.523% One-month SOFR

FAIR VALUE MEASUREMENT

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 September 30, 2024 December 31, 2023 Assets: Money market funds Level I $ 120,002 $ 49,541 Interest rate swap contracts Level II 4,691 112,914 Liabilities: Interest rate swap contracts Level II 1,907 — Contingent consideration related to acquisitions Level III 6,189 2,037 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. 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 fair value of notes payable is based primarily on the present value of the remaining payments discounted at the borrowing cost. 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 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: September 30, 2024 December 31, 2023 Fair Value Carrying Estimated Carrying Estimated Credit facility debt Level II $ 7,062,391 $ 7,114,413 $ 8,257,682 $ 8,323,654 Senior guaranteed notes and senior secured notes Level II 11,117,098 9,375,275 9,079,882 7,784,288 Senior notes Level II 6,586,850 3,674,638 7,334,447 4,932,931 Notes payable and supply chain financing Level II 128,695 128,695 174,594 174,594 $ 24,895,034 $ 20,293,021 $ 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 We use an estimated annual effective tax rate ("AETR") to measure the income tax expense or benefit recognized on a year-to-date basis in an interim period. In addition, certain items included in income tax expense as well as the tax impact of certain items included in pretax income must be treated as discrete items. The income tax expense or benefit associated with these discrete items is fully recognized in the interim period in which the items occur. Altice USA For the three and nine months ended September 30, 2024, we recorded a tax benefit (expense) of $9,892 and $(42,045) on pre-tax income (loss) of $(50,727) and $10,016, respectively. For the three months ended September 30, 2024, the effective tax rate was lower than the U.S. statutory tax rate primarily due to the increase in tax deficiencies on share-based compensation. For the nine months ended September 30, 2024, the effective tax rate was higher than the U.S. statutory rate, due to increased state tax expense, primarily from a discrete adjustment of $19,472 from the enacted corporate tax rate increase in New Jersey. In addition, the higher rate for the nine month period is due to the impact of certain non-deductible expenses and tax deficiencies on share-based compensation. For the three and nine months ended September 30, 2023, we recorded a tax expense of $27,336 and $106,433 on pre-tax income of $102,851 and $299,262, respectively, resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher tax rate was due to the impact of certain non-deductible expenses, state tax expense, and tax deficiencies on share-based compensation. CSC Holdings For the three and nine months ended September 30, 2024, we recorded a tax benefit (expense) of $10,064 and $(41,873) on pre-tax income (loss) of $(51,589) and $9,154, respectively. For the three months ended September 30, 2024, the effective tax rate was lower than the U.S. statutory tax rate primarily due to the increase in tax deficiencies on share-based compensation. For the nine months ended September 30, 2024, the effective tax rate was higher than the U.S. statutory rate, due to increased state tax expense, primarily from a discrete adjustment of $19,472 from the enacted corporate tax rate increase in New Jersey. In addition, the higher rate for the nine month period is due to the impact of certain non-deductible expenses and tax deficiencies on share-based compensation. For the three and nine months ended September 30, 2023, we recorded a tax expense of $27,336 and $106,433 on pre-tax income of $102,851 and $299,262, respectively, resulting in an effective tax rate that was higher than the U.S. statutory tax rate.

COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES 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. 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. 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.
