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, 2022. 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, 2023. 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 10 for a discussion of fair value estimates.

Earnings Per Share [Abstract]
Earnings Per Share	NET INCOME 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. 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: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 (in thousands) Basic weighted average shares outstanding 454,688 453,230 454,687 453,230 Effect of dilution: Restricted stock — — 122 — Deferred cash-denominated awards (Note 12) — — 330 — Diluted weighted average shares outstanding 454,688 453,230 455,139 453,230 Weighted average shares excluded from diluted weighted average shares outstanding: Anti-dilutive shares 43,740 57,921 47,121 58,160 Share-based compensation awards whose performance metrics have not been achieved 24,795 7,445 15,907 7,574 Net income 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.

The revolving credit facility is due on the earlier of (i) July 13, 2027 and (ii) April 17, 2025 if, as of such date, any Term Loan B borrowings are still outstanding, unless the Term Loan B maturity date has been extended to a date falling after July 13, 2027. 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. (c) The revolving credit facility provides for commitments in an aggregate principal amount of $2,475,000 and is priced at Secured Overnight Financing Rate ("SOFR") plus 2.25%. (d) Includes $168,281 related to supply chain financing agreements that is required to be repaid within one year from the date of the respective agreement. (e) There were no borrowings outstanding under the Lightpath Revolving Credit Facility which provides for commitments in an aggregate principal amount of $100,000. (f) The indebtedness was collateralized by shares of Comcast common stock. In January 2023, the Company settled this debt by delivering shares of Comcast common stock and the related equity derivative contracts. See Note 9. (g) Pursuant to the term loan agreement, the interest rate on outstanding borrowings subsequent to the phase-out of London Interbank Offered Rate ("LIBOR") as of June 30, 2023, is Synthetic USD LIBOR, calculated as Term SOFR plus the spread adjustment for the corresponding LIBOR setting, being 0.11448% (1 month), 0.26161% (3 month) and 0.42826% (6 month), until September 30, 2024. For financing purposes, the Company has two debt silos: CSC Holdings and Lightpath. The CSC Holdings silo is structured as a restricted group (the "Restricted Group") and an unrestricted group, which includes certain designated subsidiaries and investments. The Restricted Group is comprised of CSC Holdings and substantially all of its wholly-owned operating subsidiaries excluding Cablevision Lightpath LLC ("Lightpath"), a 50.01% owned subsidiary of the Company, which became an unrestricted subsidiary in September 2020. These 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. Both CSC Holdings and Lightpath's credit facilities agreements contain 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 credit facilities will be entitled to take various actions, including the acceleration of amounts due under the credit facilities and all actions permitted to be taken by a secured creditor. Senior Guaranteed Notes 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. The Company used the proceeds to repay outstanding borrowings drawn under the Revolving Credit Facility. As of June 30, 2023, 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. Lightpath Credit Facility In June 2023, Lightpath entered into an amendment (the "First Amendment") under its existing credit facility 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. Supply Chain Financing Arrangement The Company has a supply chain financing arrangement with a financial institution with credit availability of $175,000 that is used to finance certain of its property and equipment purchases. This arrangement extends the Company's 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. Amounts outstanding under this arrangement amounted to $168,281 and $123,880 as of June 30, 2023 and December 31, 2022, respectively. Summary of Debt Maturities The future principal payments under the Company's various debt obligations outstanding as of June 30, 2023, including notes payable and supply chain financing, but excluding finance lease obligations, are as follows: 2023 $ 118,277 2024 915,391 2025 (a) 2,391,414 2026 567,223 2027 5,141,519 Thereafter (b) 15,796,850

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS	DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS Prepaid Forward Contracts Historically, the Company had entered into various transactions to limit the exposure against equity price risk on shares of Comcast Corporation ("Comcast") common stock it previously owned. The Company monetized all of its stock holdings in Comcast through the execution of prepaid forward contracts, collateralized by an equivalent amount of the respective underlying stock. The Company received cash proceeds upon execution of the prepaid forward contracts which had been reflected as collateralized indebtedness in the accompanying consolidated balance sheet as of December 31, 2022. In addition, the Company separately accounted for the equity derivative component of the prepaid forward contracts. These equity derivatives were not designated as hedges for accounting purposes, therefore, the net fair values of the equity derivatives had been reflected in the accompanying consolidated balance sheet as an asset at December 31, 2022, and the net increases or decreases in the fair value of the equity derivative component of the prepaid forward contracts were included in gain (loss) on derivative contracts in the accompanying consolidated statements of operations. In January 2023, the Company settled its outstanding collateralized indebtedness by delivering the Comcast shares it held and the related equity derivative contracts. In connection with the settlement, the Company received 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 June 30, 2023, the Company did not hold and has 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 the Company 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 a 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.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	6 Months Ended
	Jun. 30, 2023
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 the Company's 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 June 30, 2023 December 31, 2022 Assets: Money market funds Level I $ 86,067 $ 141,137 Investment securities pledged as collateral (a) Level I — 1,502,145 Prepaid forward contracts (a) Level II — 263,873 Interest rate swap contracts Level II 192,113 185,622 Liabilities: Contingent consideration related to acquisition Level III 2,073 8,383 (a) In January 2023, the Company settled its outstanding collateralized indebtedness by delivering the Comcast shares it held and the related equity derivative contracts. The Company's money market funds which are classified as cash equivalents and investment securities pledged as collateral are classified within Level I of the fair value hierarchy because they are valued using quoted market prices. The Company's derivative contracts and liabilities under derivative contracts on the Company's 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, the Company has concluded that these instruments should be classified within Level II of the fair value hierarchy. The fair values of the contingent consideration as of June 30, 2023 and December 31, 2022 relate to an acquisition in the third quarter of 2022 and were 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, Collateralized Indebtedness, Senior Notes, Senior Guaranteed Notes, Senior Secured Notes, Notes Payable, and Supply Chain Financing The fair values of each of the Company's debt instruments are based on quoted market prices for the same or similar issues or on the current rates offered to the Company for instruments of the same remaining maturities. 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 the Company's financial instruments, excluding those that are carried at fair value in the accompanying consolidated balance sheets, are summarized below: June 30, 2023 December 31, 2022 Fair Value Carrying Estimated Carrying Estimated Credit facility debt Level II $ 8,287,902 $ 8,361,978 $ 9,063,495 $ 9,145,298 Collateralized indebtedness (b) Level II — — 1,746,281 1,731,771 Senior guaranteed notes and senior secured notes Level II 9,077,169 7,116,168 8,081,489 6,154,075 Senior notes Level II 7,329,183 3,933,740 7,324,238 4,531,300 Notes payable and supply chain financing Level II 168,696 168,696 127,635 127,608 $ 24,862,950 $ 19,580,582 $ 26,343,138 $ 21,690,052 (a) Amounts are net of unamortized deferred financing costs and discounts/premiums. (b) In January 2023, the Company settled its outstanding collateralized indebtedness by delivering the Comcast shares it held and the related equity derivative contracts.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company uses 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. For the three and six months ended June 30, 2023, the Company recorded a tax expense of $48,725 and $79,097 on pre-tax income of $134,869 and $196,411, respectively, resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher tax rate was primarily due to the impact of certain non-deductible expenses, state tax expense, and tax deficiencies on share-based compensation. For the three and six months ended June 30, 2022, the Company recorded a tax expense of $33,890 and $116,736 on pre-tax income of $147,430 and $432,417, 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 and state tax expense.

COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Matters On December 14, 2022, BMG Rights Management (US) LLC, UMG Recordings, Inc., Capitol Records, LLC, Concord Music Group, Inc., and Concord Bicycle Assets, LLC (collectively, “BMG” or “Plaintiffs”) filed a complaint in the U.S. District Court for the Eastern District of Texas, alleging that certain of the Company’s Internet subscribers directly infringed over 7,700 of Plaintiffs’ copyrighted works. Plaintiffs seek to hold the Company liable for claims of contributory infringement of copyright and vicarious copyright infringement. The Company intends to vigorously defend these claims. The Company also receives notices from third parties, and in some cases is named as a defendant in lawsuits, claiming infringement of various patents or copyrights relating to various aspects of the Company's businesses. In certain of these cases other industry participants are also defendants, and in certain of these cases the Company expects that some or all potential liability would be the responsibility of the Company's vendors pursuant to applicable contractual indemnification provisions. In the event that the Company is found to infringe on any patent or other intellectual property rights, the Company may be subject to substantial damages or an injunction that could require the Company or its vendors to modify certain products and services the Company offers to its subscribers, as well as enter into royalty or license agreements with respect to the patents at issue. The Company is also party to various other lawsuits, disputes and investigations arising in the ordinary course of its 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 the Company's 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 the operations or financial position of the Company or the ability of the Company to meet its financial obligations as they become due, but they could be material to the Company’s consolidated results of operations or cash flows for any one period.
