Part I.        FINANCIAL INFORMATION

This Form 10-Q contains statements that constitute forward-looking information within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act and Section 21E of the Securities Act of 1934, as amended.  In this Form 10-Q there are statements concerning our future operating results and future financial performance. Words such as "expects", "anticipates", "believes", "estimates", "may", "will", "should", "could", "potential", "continue", "intends", "plans" and similar words and terms used in the discussion of future operating results, future financial performance and future events identify forward-looking statements.  Investors are cautioned that such forward-looking statements are not guarantees of future performance, results or events and involve risks and uncertainties and that actual results or developments may differ materially from the forward-looking statements as a result of various factors. 

We operate in a highly competitive, consumer and technology driven and rapidly changing business that is affected by government regulation and economic, strategic, technological, political and social conditions. Various factors could adversely affect our operations, business or financial results in the future and cause our actual results to differ materially from those contained in the forward-looking statements. In addition, important factors that could cause our actual results to differ materially from those in our forward-looking statements include:

•competition for broadband, video and telephony customers from existing competitors (such as broadband communications companies, direct broadcast satellite providers, wireless data and telephony providers, and Internet-based providers) and new fiber-based competitors entering our footprint;

•changes in consumer preferences, laws and regulations or technology that may cause us to change our operational strategies;

•increased difficulty negotiating programming agreements on favorable terms, if at all, resulting in increased costs to us and/or the loss of popular programming;

•increasing programming costs and delivery expenses related to our products and services;

•our ability to achieve anticipated customer and revenue growth, to successfully introduce new products and services and to implement our growth strategy;

•our ability to complete our capital investment plans on time and on budget, including our plan to build a parallel fiber-to-the-home ("FTTH") network;

•our ability to develop mobile voice and data services and our ability to attract customers to these services;

•the effects of economic conditions or other factors which may negatively affect our customers’ demand for our current and future products and services;

•the effects of industry conditions;

•demand for digital and linear advertising products and services;

•our substantial indebtedness and debt service obligations;

•adverse changes in the credit market;

•changes as a result of any tax reforms that may affect our business;

•financial community and rating agency perceptions of our business, operations, financial condition and the industries in which we operate;

•the restrictions contained in our financing agreements;

•our ability to generate sufficient cash flow to meet our debt service obligations;

•fluctuations in interest rates which may cause our interest expense to vary from quarter to quarter;

•technical failures, equipment defects, physical or electronic break-ins to our services, computer viruses and similar problems;

2

•cybersecurity incidents as a result of hacking, phishing, denial of service attacks, dissemination of computer viruses, ransomware and other malicious software, misappropriation of data, and other malicious attempts;

•disruptions to our networks, infrastructure and facilities as a result of natural disasters, power outages, accidents, maintenance failures, telecommunications failures, degradation of plant assets, terrorist attacks and similar events;

•labor shortages and supply chain disruptions;

•our ability to obtain necessary hardware, software, communications equipment and services and other items from our vendors at reasonable costs;

•our ability to effectively integrate acquisitions and to maximize expected operating efficiencies from our acquisitions or as a result of the transactions, if any;

•significant unanticipated increases in the use of bandwidth-intensive Internet-based services;

•the outcome of litigation, government investigations and other proceedings; and

•other risks and uncertainties inherent in our cable and broadband communications businesses and our other businesses, including those listed under the caption "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 22, 2023 (the "Annual Report").

These factors are not necessarily all of the important factors that could cause our actual results to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors could cause our actual results to differ materially from those expressed in any of our forward-looking statements.

Given these uncertainties, you are cautioned not to place undue reliance on such forward-looking statements. The forward-looking statements are made only as of the date of this Quarterly Report. Except to the extent required by law, we do not undertake, and specifically decline any obligation, to update any forward-looking statements or to publicly announce the results of any revisions to any of such statements to reflect future events or developments. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

You should read this Quarterly Report with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect. We qualify all forward-looking statements by these cautionary statements.

Certain numerical figures included in this Quarterly Report have been subject to rounding adjustments. Accordingly, such numerical figures shown as totals in various tables may not be arithmetic aggregations of the figures that precede them.

NOTE 1.    DESCRIPTION OF BUSINESS AND RELATED MATTERS

The Company and Related Matters

Altice USA, Inc. ("Altice USA") was incorporated in Delaware on September 14, 2015. Altice USA is majority-owned by Patrick Drahi through Next Alt S.à r.l. ("Next Alt"). Patrick Drahi also controls Altice Group Lux S.à r.l, formerly Altice Europe N.V. ("Altice Europe") and its subsidiaries and other entities.

Altice USA, through CSC Holdings, LLC and its consolidated subsidiaries ("CSC Holdings," and collectively with Altice USA, the "Company"), principally provides broadband communications and video services in the United States. It markets its residential services under the Optimum brand and provides enterprise services under the brands Lightpath and Optimum Business. It delivers broadband, video, telephony services, proprietary content and advertising services to residential and business customers. In addition, the Company offers a full-service mobile offering to consumers across its footprint. As these brands are managed on a consolidated basis, the Company classifies its operations in one segment.

The accompanying consolidated financial statements ("consolidated financial statements") of Altice USA include the accounts of Altice USA and its majority-owned subsidiaries and the accompanying consolidated financial statements of CSC Holdings include the accounts of CSC Holdings and its majority-owned subsidiaries. Altice USA is a holding company and has no business operations independent of its CSC Holdings subsidiary, whose operating results and financial position are consolidated into Altice USA. The consolidated balance sheets and statements of operations of Altice USA are essentially identical to the consolidated balance sheets and statements of operations of CSC Holdings, with the following exceptions: Altice USA has additional cash and CSC Holdings has a higher deferred tax liability on their respective consolidated balance sheets.

The combined notes to the consolidated financial statements relate to the Company, which, except as noted, are essentially identical for Altice USA and CSC Holdings. All significant intercompany transactions and balances between Altice USA or CSC Holdings and their respective consolidated subsidiaries are eliminated in both sets of consolidated financial statements. Intercompany transactions between Altice USA and CSC Holdings are not eliminated in the CSC Holdings consolidated financial statements, but they are eliminated in the Altice USA consolidated financial statements.

The financial statements of CSC Holdings are included herein as supplemental information as CSC Holdings is not an SEC registrant.

NOTE 2.    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, 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.

(a)Beginning in the second quarter of 2023, mobile service revenue previously included in mobile revenue is now separately reported in residential revenue and business services revenue. In addition, mobile equipment revenue previously included in mobile revenue is now included in other revenue. Prior period amounts have been revised to conform with this presentation.

The Company is assessed non-income related taxes by governmental authorities, including franchising authorities (generally under multi-year agreements), and collects such taxes from its customers. In instances where the tax is being assessed directly on the Company, 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 three and nine months ended September 30, 2023, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $53,989 and $165,691, respectively. For the three and nine months ended September 30, 2022, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $59,371 and $177,032, respectively.

Customer Contract Costs

Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheets and totaled $18,685 and $17,511 as of September 30, 2023 and December 31, 2022, respectively.

A significant portion of our revenue is derived from residential and small and medium-sized business ("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.

NOTE 5.    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 September 30,		Nine Months Ended September 30,
	2023	2022	2023	2022

(b)At September 30, 2023, $133,512 of the revolving credit facility was restricted for certain letters of credit issued on behalf of the Company and $1,491,488 of the facility was undrawn and available, subject to covenant limitations. 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 $174,998 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 September 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 $174,998 and $123,880 as of September 30, 2023 and December 31, 2022, respectively.

NOTE 9.    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 September 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 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 April 2023, Lightpath entered into an interest rate swap contract, effective June 2023 on a notional amount of $180,000, whereby Lightpath pays interest of 3.523% through December 2026 and receives interest based on one-month SOFR. This swap contract is also not designated as a hedge for accounting purposes. Accordingly, this contract is carried at its fair market value on our consolidated balance sheet, with changes in fair value reflected in the consolidated statements of operations.

NOTE 10.    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 Hierarchy	September 30, 2023		December 31, 2022
Assets:
Money market funds	Level I	$	106,976	$	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	187,313		185,622
Liabilities:
Contingent consideration related to acquisition	Level III	1,947		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 September 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:

		September 30, 2023				December 31, 2022
	Fair Value Hierarchy	Carrying Amount (a)		Estimated Fair Value		Carrying Amount (a)		Estimated Fair Value
Credit facility debt	Level II	$	8,297,765	$	8,367,816	$	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	9,078,516		7,307,125		8,081,489		6,154,075

Notes payable and supply chain financing	Level II	175,276		175,276		127,635		127,608
		$	24,883,343	$	20,326,017	$	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.

The fair value estimates related to the Company's debt instruments presented above are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgments and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

NOTE 11.    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 nine months ended September 30, 2023, the Company 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 primarily due to the impact of certain non-deductible expenses, state tax expense, and tax deficiencies on share-based compensation.

For the three and nine months ended September 30, 2022, the Company recorded a tax expense of $35,827 and $152,563 on pre-tax income of $133,448 and $565,865, 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.

(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 canceled in connection with the Company's stock option exchange program discussed below.

As of September 30, 2023, the total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of approximately 2.71 years.

In January 2023, the Company 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 ten dollars of DCAs for every seven eligible options tendered. In connection with the Exchange Offer, the Company 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, the Company will recognize the unamortized compensation cost related to the canceled 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.

NOTE 14.    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.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

All dollar amounts, except per customer and per share data, included in the following discussion, are presented in thousands.

The preparation of our consolidated financial statements requires us to make estimates that affect the reported amounts of assets, liabilities, revenue and expenses. For a complete discussion of the accounting judgments and estimates that we have identified as critical in the preparation of our consolidated financial statements, please refer to our Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2022.

Overview

Our Business

We principally provide broadband communications and video services in the United States and market our services primarily under the Optimum brand. We deliver broadband, video, telephony, and mobile services to residential and business customers across our footprint. Our footprint extends across 21 states (primarily in the New York metropolitan area and various markets in the south-central United States) through a fiber-rich hybrid-fiber coaxial ("HFC") broadband network and a FTTH network. Additionally, we offer news programming and advertising services.

Key Factors Impacting Operating Results and Financial Condition

Our future performance is dependent, to a large extent, on the impact of direct competition, general economic conditions (including capital and credit market conditions), our ability to manage our businesses effectively, and our relative strength and leverage in the marketplace, both with suppliers and customers. For more information, see "Risk Factors" and "Business-Competition" included in our Annual Report on Form 10-K for the year ended December 31, 2022 and the cautionary statement regarding forward-looking statements included in this Quarterly Report.

We derive revenue principally through monthly charges to residential customers of our broadband, video, telephony and mobile services. We also derive revenue from digital video recorder, video-on-demand ("VOD"), pay-per-view, installation and home shopping commissions. Our residential broadband, video, telephony and mobile services accounted for approximately 42%, 33%, 3%, and 1%, respectively, of our consolidated revenue for the nine months ended September 30, 2023. We also derive revenue from the sale of a wide and growing variety of products and services to both large enterprise and small and medium-sized business ("SMB") customers, including broadband, telephony, networking, video, and mobile services. For the nine months ended September 30, 2023, 16% of our consolidated revenue was derived from these business services. In addition, we derive revenues from the sale of advertising time available on the programming carried on our cable television systems, digital advertising, affiliation fees for news programming, and data analytics, which accounted for approximately 5% of our consolidated revenue for the nine months ended September 30, 2023. Our other revenue, which includes mobile equipment revenue, for the nine months ended September 30, 2023 accounted for less than 1% of our consolidated revenue.

Revenue is impacted by rate increases, changes in the amount of promotional offerings, changes in the number of customers that subscribe to our services, including additional services sold to our existing customers, programming package changes by our video customers, speed tier changes by our broadband customers, acquisitions/dispositions, and construction of cable systems that result in the addition of new customers. Additionally, the allocation of revenue between the residential offerings is impacted by changes in the standalone selling price of each performance obligation within our promotional bundled offers.

Our ability to increase the number of customers to our services is significantly related to our penetration rates.

We operate in a highly competitive consumer-driven industry and we compete against a variety of broadband, video, mobile, fixed wireless broadband and fixed-line telephony providers and delivery systems, including broadband communications companies, wireless data and telephony providers, fiber-based service providers, satellite delivered video signals, Internet-delivered video content and broadcast television signals available to residential and business customers in our service areas. Our competitors include AT&T, Inc., DirecTV, DISH Network Corporation, Frontier Communications Corporation, Lumen Technologies, Inc., T-Mobile US, Inc., and Verizon Communications Inc. Consumers' selection of an alternate source of service, whether due to economic constraints, technological advances, or preference, negatively impacts the demand for our services. For more information on our competitive landscape,

32

see "Risk Factors" and "Business-Competition" included in our Annual Report on Form 10-K for the year ended December 31, 2022.

Our programming costs, which are the most significant component of our operating expenses, are impacted by increases in contractual rates, changes in the number of customers receiving certain programming services, and new channel launches. We expect contractual rates to increase in the future. See "Results of Operations" below for more information regarding the key factors impacting our revenues and operating expenses.

Historically, we have made substantial investments in our network and the development of new and innovative products and other service offerings for our customers as a way of differentiating ourselves from our competitors and we expect to do so in the future. Our ongoing FTTH network build enables us to deliver multi-gig broadband speeds to FTTH customers in order to meet the growing data needs of residential and business customers. In addition, we have launched a full service mobile offering to consumers across our footprint. We may incur greater than anticipated capital expenditures in connection with these initiatives, fail to realize anticipated benefits, experience delays and business disruptions or encounter other challenges to executing them as planned. See "Liquidity and Capital Resources- Capital Expenditures" for additional information regarding our capital expenditures.

Non-GAAP Financial Measures

We define Adjusted EBITDA, which is a non-GAAP financial measure, as net income (loss) excluding income taxes, non-operating income or expenses, gain (loss) on extinguishment of debt and write-off of deferred financing costs, gain (loss) on interest rate swap contracts, gain (loss) on derivative contracts, gain (loss) on investments and sale of affiliate interests, interest expense, net, depreciation and amortization, share-based compensation, restructuring expense and other operating items (such as significant legal settlements, contractual payments for terminated employees, and impairments). See reconciliation of net income to Adjusted EBITDA below.

Adjusted EBITDA eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of our business and from intangible assets recognized from acquisitions, as well as certain non-cash and other operating items that affect the period-to-period comparability of our operating performance. In addition, Adjusted EBITDA is unaffected by our capital and tax structures and by our investment activities.

We believe Adjusted EBITDA is an appropriate measure for evaluating the operating performance of the Company. Adjusted EBITDA and similar measures with similar titles are common performance measures used by investors, analysts and peers to compare performance in our industry. Internally, we use revenue and Adjusted EBITDA measures as important indicators of our business performance and evaluate management’s effectiveness with specific reference to these indicators. We believe Adjusted EBITDA provides management and investors a useful measure for period-to-period comparisons of our core business and operating results by excluding items that are not comparable across reporting periods or that do not otherwise relate to the Company’s ongoing operating results. Adjusted EBITDA should be viewed as a supplement to and not a substitute for operating income (loss), net income (loss), and other measures of performance presented in accordance with GAAP. Since Adjusted EBITDA is not a measure of performance calculated in accordance with GAAP, this measure may not be comparable to similar measures with similar titles used by other companies.

We also use Operating Free Cash Flow (defined as Adjusted EBITDA less cash capital expenditures), and Free Cash Flow (defined as net cash flows from operating activities less cash capital expenditures) as indicators of the Company’s financial performance. We believe these measures are two of several benchmarks used by investors, analysts and peers for comparison of performance in our industry, although they may not be directly comparable to similar measures reported by other companies.

Comparison of Results for the Three and Nine Months Ended September 30, 2023 compared to the Three and Nine Months Ended September 30, 2022

Broadband Revenue

Broadband revenue for the three and nine months ended September 30, 2023 was $961,751 and $2,884,661, respectively, and $981,842 and $2,970,039, for the three and nine months ended September 30, 2022, respectively. Broadband revenue is derived principally through monthly charges to residential subscribers of our broadband services. Revenue is impacted by rate increases, changes in the amount of promotional offerings, changes in the number of customers, and changes in speed tiers. Additionally, the allocation of revenue between the residential offerings is impacted by changes in the standalone selling price of each performance obligation within our promotional bundled offers.

Broadband revenue decreased $20,091 (2%) and $85,378 (3%) for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022. The decrease for the three months ended September 30, 2023 was due to a decline in broadband customers. The decrease for the nine months ended September 30, 2023 was due to a decline in broadband customers and lower average recurring broadband revenue per broadband customer.

Video Revenue

Video revenue for the three and nine months ended September 30, 2023 was $775,818 and $2,321,557, respectively, and $816,001 and $2,499,437, for the three and nine months ended September 30, 2022, respectively. Video revenue is derived principally through monthly charges to residential customers of our video services. Revenue is impacted by rate increases, changes in the amount of promotional offerings, changes in the number of customers, additional services sold to our existing customers, and changes in programming packages. Additionally, the allocation of revenue between the residential offerings is impacted by changes in the standalone selling price of each performance obligation within our promotional bundled offers.

Video revenue decreased $40,183 (5%) and $177,880 (7%) for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022. These decreases were due to a decline in video customers, partially offset by higher average recurring video revenue per video customer, primarily driven by certain rate increases.

Telephony Revenue

Telephony revenue for the three and nine months ended September 30, 2023 was $73,640 and $227,390, respectively, and $83,097 and $252,952, for the three and nine months ended September 30, 2022, respectively. Telephony revenue is derived principally through monthly charges to residential customers of our telephony services. Revenue is impacted by changes in rates for services, changes in the amount of promotional offerings, changes in the number of customers, and additional services sold to our existing customers. Additionally, the allocation of revenue between the residential offerings is impacted by changes in the standalone selling price of each performance obligation within our promotional bundled offers.

Telephony revenue decreased $9,457 (11%) and $25,562 (10%) for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022. The decrease for the three months ended September 30, 2023 was due to a decline in telephony customers. The decrease for the nine months ended September 30, 2023 was due to a decline in telephony customers, partially offset by higher average recurring telephony revenue per telephony customer.

Mobile Service Revenue

Mobile service revenue for the three and nine months ended September 30, 2023 was $20,320 and $53,993, respectively, and $15,216 and $47,021 for the three and nine months ended September 30, 2022, respectively. Mobile service revenue increased $5,104 (34%) and $6,972 (15%) for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022. The increase for the three month period was due primarily to a decline in customers receiving free service during the three months ended September 30, 2023 as compared to the same period in the prior year and an increase in mobile customers. The increase for the nine month

37

period was due primarily to an increase in mobile customers, as well as a decline in customers receiving free service as compared to the same period in the prior year.

Business Services and Wholesale Revenue

Business services and wholesale revenue for the three and nine months ended September 30, 2023 was $366,852 and $1,095,197, respectively, and $366,662 and $1,105,905 for the three and nine months ended September 30, 2022, respectively. Business services and wholesale revenue is derived primarily from the sale of fiber-based telecommunications services to the business market, and the sale of broadband, video, telephony, and mobile services to SMB customers.

Business services and wholesale revenue increased $190 for the three months ended and decreased $10,708 (1%) for the nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022, respectively. The decrease for the nine month period was due to lower SMB revenue, lower backhaul revenue attributable to wholesale customers and lower contract termination fee revenue.

News and Advertising Revenue

News and advertising revenue for the three and nine months ended September 30, 2023 was $107,484 and $319,686, respectively, and $120,522 and $368,447 for the three and nine months ended September 30, 2022, respectively. 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, and (iii) data analytics. News and advertising revenue also includes affiliation fees for news programming.

News and advertising revenue decreased $13,038 (11%) and $48,761 (13%) for the three and nine months ended September 30, 2023, compared to the three and nine months ended September 30, 2022 primarily due to a decrease in linear advertising revenue.

Other Revenue

Other revenue for the three and nine months ended September 30, 2023 was $11,335 and $32,968, respectively, and $10,212 and $34,662, for the three and nine months ended September 30, 2022, respectively. Other revenue includes revenue from sales of mobile equipment and other miscellaneous revenue streams.

Programming and Other Direct Costs

Programming and other direct costs for the three and nine months ended September 30, 2023 amounted to $750,538 and $2,284,537, respectively, and $782,121 and $2,429,925, for the three and nine months ended September 30, 2022, respectively. Programming and other direct costs include cable programming costs, which are costs paid to programmers (net of amortization of any incentives received from programmers for carriage) for cable content (including costs of VOD and pay-per-view) and are generally paid on a per-customer basis. These costs are impacted by increases in contractual rates, changes in the number of customers receiving certain programming services, and new channel launches. These costs also include interconnection, call completion, circuit and transport fees paid to other telecommunication companies for the transport and termination of voice and data services, which typically vary based on rate changes and the level of usage by our customers. These costs also include franchise fees which are payable to the state governments and local municipalities where we operate and are primarily based on a percentage of certain categories of revenue derived from the provision of video service over our cable systems, which vary by state and municipality. These costs change in relation to changes in such categories of revenues or rate changes. Additionally, these costs include the cost of media advertising spots for resale, the cost of mobile devices sold to our customers and direct costs of providing mobile services.

38

The decreases of $31,583 (4%) and $145,388 (6%) for the three and nine months ended September 30, 2023 as compared to the three and nine months ended September 30, 2022 were primarily attributable to the following:

	Three Months		Nine Months
Decrease in programming costs primarily due to lower video customers, partially offset by net contractual rate increases	$	(44,636)	$	(138,163)
Increase (decrease) in taxes and surcharges. The decrease for the nine month period was primarily due to refunds.	6,015		(10,346)
Decrease in software license fees related to customer premise equipment	(1,013)		(10,495)
Increase in costs of media advertising spots for resale, primarily linear spots resulting from an acquisition in the third quarter of 2022	7,197		18,175
Other net increases (decreases)	854		(4,559)
	$	(31,583)	$	(145,388)

Programming costs

Programming costs aggregated $606,132 and $1,869,235, respectively, for the three and nine months ended September 30, 2023, and $650,768 and $2,007,398 for the three and nine months ended September 30, 2022, respectively. Our programming costs in 2023 will continue to be impacted by changes in programming rates, which we expect to increase, and by changes in the number of video customers.

Other Operating Expenses

Other operating expenses for the three and nine months ended September 30, 2023 amounted to $667,278 and $1,974,651, respectively, and for the three and nine months ended September 30, 2022 amounted to $694,390 and $2,009,760, respectively. Other operating expenses include staff costs and employee benefits including salaries of company employees and related taxes, benefits and other employee related expenses, as well as third-party labor costs. Other operating expenses also include network management and field service costs, which represent costs associated with the maintenance of our broadband network, including costs of certain customer connections and other costs associated with providing and maintaining services to our customers.

Customer installation and network repair and maintenance costs may fluctuate as a result of changes in the level of activities and the utilization of contractors as compared to employees. Also, customer installation costs fluctuate as the portion of our expenses that we are able to capitalize changes. Costs associated with the initial deployment of new customer premise equipment necessary to provide broadband, video and telephony services are capitalized (asset-based). The redeployment of customer premise equipment is expensed as incurred.

Other operating expenses also include costs related to our call center operations that handle customer inquiries and billing and collection activities, and sales and marketing costs, which include advertising production and placement costs associated with acquiring and retaining customers. These costs vary period to period and certain of these costs, such as sales and marketing, may increase with intense competition. Additionally, other operating expenses include various other administrative costs.

The decreases in other operating expenses of $27,112 (4%) and $35,109 (2%) for the three and nine months ended September 30, 2023 as compared to the three and nine months ended September 30, 2022 were attributable to the following:

	Three Months		Nine Months
Net increase in labor costs and benefits, partially offset by an increase in capitalizable activity	$	4,635	$	53,912
Increase in repairs and maintenance costs, net of capitalizable activity	7,270		15,821
Increase in utility costs	607		7,586
Decrease in bad debt	(10,240)		(3,133)
Decrease in share-based compensation including credits resulting from the modification of awards to certain former executive officers primarily in the three months ended March 31, 2023	(21,234)		(85,042)
Decrease in marketing costs due to costs incurred in 2022 from the rebranding of our services from Suddenlink to Optimum	(10,321)		(30,443)
Other net increases, net of capitalizable activity	2,171		6,190
	$	(27,112)	$	(35,109)

Restructuring Expense and Other Operating Items

Restructuring expense and other operating items for the three and nine months ended September 30, 2023 amounted to $4,453 and $39,303, respectively, as compared to $4,007 and $10,058 for the three and nine months ended September 30, 2022, respectively, and comprised the following:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022

	$	4,453	$	4,007	$	39,303	$	10,058

Depreciation and Amortization

Depreciation and amortization for the three and nine months ended September 30, 2023 amounted to $402,366 and $1,237,283, respectively, as compared to $445,769 and $1,327,243 for the three and nine months ended September 30, 2022, respectively.

The decreases in depreciation and amortization of $43,403 and $89,960 for the three and nine months ended September 30, 2023 as compared to the three and nine months ended September 30, 2022 was due to lower amortization expense resulting from certain assets becoming fully amortized, partially offset by higher depreciation expense resulting from increased asset additions in 2023.

Adjusted EBITDA

Adjusted EBITDA amounted to $915,499 and $2,705,632, respectively, for the three and nine months ended September 30, 2023 as compared to $954,390 and $2,953,188 for the three and nine months ended September 30, 2022, respectively.

Adjusted EBITDA is a non-GAAP measure that is defined as net income (loss) excluding income taxes, non-operating income or expenses, loss on extinguishment of debt and write-off of deferred financing costs, gain (loss) on interest rate swap contracts, gain (loss) on derivative contracts, gain (loss) on investments and sale of affiliate interests, interest expense, net, depreciation and amortization (including impairments), share-based compensation, restructuring expense and other operating items (such as significant legal settlements, contractual payments for terminated employees, and impairments). See reconciliation of net income (loss) to adjusted EBITDA above.

The decreases in Adjusted EBITDA of $38,891 and $247,556 for the three and nine months ended September 30, 2023 as compared to the three and nine months ended September 30, 2022, respectively, were due to the decreases in revenue, partially offset by decreases in operating expenses during 2023 (excluding depreciation and amortization, restructuring and other operating items and share-based compensation), as discussed above.

Operating Free Cash Flow

Operating free cash flow was $562,280 and $1,296,071, respectively, for the three and nine months ended September 30, 2023 as compared to $460,831 and $1,582,132 for the three and nine months ended September 30, 2022, respectively. The increase in operating free cash flow of $101,449 for the three months ended September 30, 2023 as compared to the same period in 2022 was due to a decrease in capital expenditures, partially offset by a decrease in Adjusted EBITDA. The decrease in operating free cash flow of $286,061 for the nine months ended September 30, 2023 as compared to the same period in 2022 was due to a decrease in Adjusted EBITDA and an increase in capital expenditures.

Free Cash Flow (Deficit)

Free cash flow (deficit) was $121,279 and $(79,376), respectively, for the three and nine months ended September 30, 2023 as compared to $135,603 and $534,660 for the three and nine months ended September 30, 2022, respectively. The decrease in free cash flow of $14,324 in the three month period was due to a decrease in net cash provided by operating activities, partially offset by a decrease in capital expenditures. The decrease in free cash flow of $614,036 in the nine month period was due to a decrease in net cash provided by operating activities and an increase in capital

40

expenditures.

Interest Expense, net

Interest expense, net was $420,216 and $1,216,203, respectively, for the three and nine months ended September 30, 2023, as compared to $340,989 and $954,564, respectively, for the same periods in the prior year. The increases of $79,227 and $261,639 for the three and nine months ended September 30, 2023 as compared to the three and nine months ended September 30, 2022 were attributable to the following:

	Three Months		Nine Months
Increase primarily due to an increase in interest rates, partially offset by a decrease in average debt balances	$	91,763	$	305,378
Lower (higher) capitalized interest related to FTTH network construction	894		(3,723)
Higher interest income	(1,107)		(4,903)
Other net decreases, primarily lower amortization of deferred financing costs and original issue discounts	(12,323)		(35,113)
	$	79,227	$	261,639

Gain (Loss) on Investments

Gain (loss) on investments was $192,010 for the nine months ended September 30, 2023 compared to $(425,686) and $(902,060) for the three and nine months ended September 30, 2022, respectively, and consisted primarily of the increase (decrease) in the fair value of the Comcast common stock owned by the Company through January 24, 2023. The effects of these gains (losses) were partially offset by the losses (gains) on the related equity derivative contracts, net described below.

Gain (Loss) on Derivative Contracts, net

Gain (loss) on derivative contracts, net for the nine months ended September 30, 2023 amounted to $(166,489) compared to $323,668 and $643,856 for the three and nine months ended September 30, 2022, respectively, and included realized and unrealized gains or losses due to the change in fair value of equity derivative contracts relating to the Comcast common stock owned by the Company through January 24, 2023. The effects of these gains (losses) are partially offset by losses (gains) on investment securities pledged as collateral, which are included in gain (loss) on investments discussed above.

Gain on Interest Rate Swap Contracts, net

Gain on interest rate swap contracts, net was $31,972 and $78,708, respectively, for the three and nine months ended September 30, 2023 compared to $105,945 and $268,960 for the three and nine months ended September 30, 2022, respectively. These amounts represent the change in the fair value of the interest rate swap contracts. These swap contracts are not designated as hedges for accounting purposes.

Other Income (Loss), net

Other income (loss), net amounted to $(1,470) and $7,165, respectively, for the three and nine months ended September 30, 2023 compared to $3,245 and $8,196 for the three and nine months ended September 30, 2022, respectively.

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 nine months ended September 30, 2022, Altice USA recorded a tax expense of $35,827 and $152,563 on pre-tax income of $133,448 and $565,865, 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.

LIQUIDITY AND CAPITAL RESOURCES

Altice USA has no operations independent of its subsidiaries. Funding for our subsidiaries has generally been provided by cash flow from their respective operations, cash on hand and borrowings under the CSC Holdings revolving credit facility and the proceeds from the issuance of securities and borrowings under syndicated term loans in the capital markets. Our decision as to the use of cash generated from operating activities, cash on hand, borrowings under the revolving credit facility or accessing the capital markets has been based upon an ongoing review of the funding needs of the business, the optimal allocation of cash resources, the timing of cash flow generation and the cost of borrowing under the revolving credit facility, debt securities and syndicated term loans.

We expect to utilize free cash flow and availability under the CSC Holdings revolving credit facility, as well as future refinancing transactions, to further extend the maturities of, or reduce the principal on, our debt obligations. The timing and terms of any refinancing transactions will be subject to, among other factors, market conditions. Additionally, we may, from time to time, depending on market conditions and other factors, use cash on hand and the proceeds from other borrowings to repay the outstanding debt securities through open market purchases, privately negotiated purchases, tender offers, or redemptions.

We believe existing cash balances, operating cash flows and availability under the CSC Holdings revolving credit facility will provide adequate funds to support our current operating plan, make planned capital expenditures and fulfill our debt service requirements for the next twelve months. However, our ability to fund our operations, make planned capital expenditures, make scheduled payments on our indebtedness and repay our indebtedness depends on our future operating performance and cash flows and our ability to access the capital markets, which, in turn, are

42

subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond our control. Competition, market disruptions or a deterioration in economic conditions could lead to lower demand for our products, as well as lower levels of advertising, and increased incidence of customers' inability to pay for the services we provide. These events would adversely impact our results of operations, cash flows and financial position. Although we currently believe amounts available under the CSC Holdings revolving credit facility will be available when, and if, needed, we can provide no assurance that access to such funds will not be impacted by adverse conditions in the financial markets or other conditions. The obligations of the financial institutions under the revolving credit facility are several and not joint and, as a result, a funding default by one or more institutions does not need to be made up by the others.

In the longer term, we may not be able to generate sufficient cash from operations to fund anticipated capital expenditures, meet all existing future contractual payment obligations and repay our debt at maturity. As a result, we could be dependent upon our continued access to the capital and credit markets to issue additional debt or equity or refinance existing debt obligations. We intend to raise significant amounts of funding over the next several years to fund capital expenditures, repay existing obligations and meet other obligations, and the failure to do so successfully could adversely affect our business. If we are unable to do so, we will need to take other actions including deferring capital expenditures, selling assets, seeking strategic investments from third parties or reducing or eliminating stock repurchases and discretionary uses of cash.

The following tables summarize the carrying value of our outstanding debt, net of unamortized deferred financing costs, discounts and premiums (excluding accrued interest) as of September 30, 2023, as well as interest expense for the nine months ended September 30, 2023:

CSC Holdings Restricted Group

For financing purposes, the Company is structured as a restricted group (the "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 Lightpath which became an unrestricted subsidiary in September 2020. These subsidiaries are subject to the covenants and restrictions of the credit facility and indentures governing the notes issued by CSC Holdings.

Sources of cash for the Restricted Group include primarily cash flow from the operations of the businesses in the Restricted Group, borrowings under its credit facility and issuance of securities in the capital markets, contributions from its parent, and, from time to time, distributions or loans from its subsidiaries. The Restricted Group's principal uses of cash include: capital spending, in particular, the capital requirements associated with the upgrade of its digital broadband, video and telephony services, including costs to build our FTTH network; debt service; distributions made to its parent to fund share repurchases; other corporate expenses and changes in working capital; and investments that it may fund from time to time.

CSC Holdings Credit Facility

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 currently provides U.S. dollar term loans currently in an aggregate principal amount of $3,000,000 ($1,524,323 outstanding at September 30, 2023) (the "CSC Term Loan Facility"), and U.S. dollar revolving loan commitments in an aggregate principal amount of $2,475,000 ($850,000 outstanding at September 30, 2023) (the "CSC Revolving Credit Facility" and, together with the CSC Term Loan Facility, 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").

In October 2018, CSC Holdings entered into a $1,275,000 ($523,061 outstanding at September 30, 2023) incremental term loan facility (the “Incremental Term Loan B-3”), in October 2019, CSC Holdings entered into a $3,000,000 ($2,895,000 outstanding at September 30, 2023) incremental term loan facility ("Incremental Term Loan B-5") and in December 2022, CSC Holdings entered into a $2,001,942 ($1,991,932 outstanding at September 30, 2023) incremental term loan facility (the "Incremental Term Loan B-6") under its existing credit facilities agreement.

44

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 "2028 Senior Guaranteed Notes"). The Company used the proceeds to repay outstanding borrowings drawn under the CSC Revolving Credit Facility. See Note 8 to our consolidated financial statements for further information regarding the 2028 Senior Guaranteed Notes.

Lightpath Credit Facility

In November 2020, Lightpath entered into a credit agreement which provides a term loan in an aggregate principal amount of $600,000 ($583,500 outstanding at September 30, 2023) and revolving loan commitments in an aggregate principal amount of $100,000. As of September 30, 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 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.

See Note 8 to our consolidated financial statements for further information on the above debt obligations.

Cash Flow Discussion

Altice USA

Operating Activities

Net cash provided by operating activities amounted to $1,330,185 for the nine months ended September 30, 2023 compared to $1,905,716 for the nine months ended September 30, 2022. 

45

The decrease in cash provided by operating activities of $575,531 in 2023 as compared to 2022 resulted from a decrease in net income before depreciation and amortization and other non-cash items of $808,678, partially offset by an increase of $233,147 due to changes in working capital (including an increase in interest payments of $240,117 and a decrease in tax payments of $3,461), as well as the timing of payments of liabilities, and collections of accounts receivable, among other items.

Investing Activities

Net cash used in investing activities for the nine months ended September 30, 2023 was $1,411,238 compared to $1,376,101 for the nine months ended September 30, 2022.

46

Share Repurchase Program

In June 2018, the Board of Directors of Altice USA authorized a share repurchase program of $2,000,000, and on July 30, 2019, the Board of Directors authorized a new incremental three-year share repurchase program of $5,000,000 that took effect following the completion in August 2019 of the $2,000,000 repurchase program. In November 2020, the Board of Directors authorized an additional $2,000,000 of share repurchases bringing the total amount of cumulative share repurchases authorized to $9,000,000. Under these repurchase programs, shares of Altice USA Class A common stock may be purchased from time to time in the open market and may include trading plans entered into with one or more brokerage firms in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934. Size and timing of these purchases will be determined based on market conditions and other factors.

For the nine months ended September 30, 2023, Altice USA did not repurchase any shares. From inception through September 30, 2023, Altice USA repurchased an aggregate of 285,507,773 shares for a total purchase price of approximately $7,808,698. These acquired shares were retired and the cost of these shares was recorded in stockholders' deficiency in the consolidated balance sheet of Altice USA. As of September 30, 2023, Altice USA had approximately $1,191,302 of availability remaining under the incremental share repurchase program which expires in November 2023.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

All dollar amounts, except per share data, included in the following discussion are presented in thousands.

Fair Value of Debt

At September 30, 2023, the fair value of our fixed rate debt, comprised of our senior guaranteed and senior secured notes, senior notes, notes payable and supply chain financing of $11,958,201 was lower than its carrying value of $16,585,578 by $4,627,377. The fair value of these financial instruments is estimated based on reference to quoted market prices for these or comparable securities. Our floating rate borrowings, comprised of our term loans and revolving credit facilities bear interest in reference to current SOFR-based market rates and thus their principal values approximate fair value. The effect of a hypothetical 100 basis point decrease in interest rates prevailing at September 30, 2023 would increase the estimated fair value of our fixed rate debt by $534,704 to $12,492,905. This estimate is based on the assumption of an immediate and parallel shift in interest rates across all maturities.

Interest Rate Risk

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 carried at their fair market values in our consolidated balance sheets, with changes in fair value reflected in the consolidated statements of operations. See Note 9 to our consolidated financial statements for a summary of interest rate swap contracts outstanding at September 30, 2023. The Company's outstanding interest rate swap contracts are not designated as hedges for accounting purposes. Accordingly, the changes in the fair value of these interest rate swap contracts are recorded through the statement of operations. For the three and nine months ended September 30, 2023, the Company recorded a gain on interest rate swap contracts of $31,972 and $78,708 and had a fair value at September 30, 2023 of $187,313 recorded as other assets, long-term on the consolidated balance sheet.

As of September 30, 2023, we did not hold and have not issued derivative instruments for trading or speculative purposes.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of Altice USA's management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined under SEC rules). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective as of September 30, 2023.

47

Changes in Internal Control

During the nine months ended September 30, 2023, there were no changes in the Company's internal control over financial reporting that materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting.

DESCRIPTION OF BUSINESS AND RELATED MATTERS

DESCRIPTION OF BUSINESS AND RELATED MATTERS

The Company and Related Matters

Altice USA, Inc. ("Altice USA") was incorporated in Delaware on September 14, 2015. Altice USA is majority-owned by Patrick Drahi through Next Alt S.à r.l. ("Next Alt"). Patrick Drahi also controls Altice Group Lux S.à r.l, formerly Altice Europe N.V. ("Altice Europe") and its subsidiaries and other entities.

Altice USA, through CSC Holdings, LLC and its consolidated subsidiaries ("CSC Holdings," and collectively with Altice USA, the "Company"), principally provides broadband communications and video services in the United States. It markets its residential services under the Optimum brand and provides enterprise services under the brands Lightpath and Optimum Business. It delivers broadband, video, telephony services, proprietary content and advertising services to residential and business customers. In addition, the Company offers a full-service mobile offering to consumers across its footprint. As these brands are managed on a consolidated basis, the Company classifies its operations in one segment.

The accompanying consolidated financial statements ("consolidated financial statements") of Altice USA include the accounts of Altice USA and its majority-owned subsidiaries and the accompanying consolidated financial statements of CSC Holdings include the accounts of CSC Holdings and its majority-owned subsidiaries. Altice USA is a holding company and has no business operations independent of its CSC Holdings subsidiary, whose operating results and financial position are consolidated into Altice USA. The consolidated balance sheets and statements of operations of Altice USA are essentially identical to the consolidated balance sheets and statements of operations of CSC Holdings, with the following exceptions: Altice USA has additional cash and CSC Holdings has a higher deferred tax liability on their respective consolidated balance sheets.

The combined notes to the consolidated financial statements relate to the Company, which, except as noted, are essentially identical for Altice USA and CSC Holdings. All significant intercompany transactions and balances between Altice USA or CSC Holdings and their respective consolidated subsidiaries are eliminated in both sets of consolidated financial statements. Intercompany transactions between Altice USA and CSC Holdings are not eliminated in the CSC Holdings consolidated financial statements, but they are eliminated in the Altice USA consolidated financial statements.

The financial statements of CSC Holdings are included herein as supplemental information as CSC Holdings is not an SEC registrant.

Basis of Presentation and Significant Accounting Policies [Text Block]

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, 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.

Total revenue	$	2,317,200	$	2,393,552	$	6,935,452	$	7,278,463

(a)Beginning in the second quarter of 2023, mobile service revenue previously included in mobile revenue is now separately reported in residential revenue and business services revenue. In addition, mobile equipment revenue previously included in mobile revenue is now included in other revenue. Prior period amounts have been revised to conform with this presentation.

The Company is assessed non-income related taxes by governmental authorities, including franchising authorities (generally under multi-year agreements), and collects such taxes from its customers. In instances where the tax is being assessed directly on the Company, 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 three and nine months ended September 30, 2023, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $53,989 and $165,691, respectively. For the three and nine months ended September 30, 2022, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $59,371 and $177,032, respectively.

Customer Contract Costs

Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheets and totaled $18,685 and $17,511 as of September 30, 2023 and December 31, 2022, respectively.

A significant portion of our revenue is derived from residential and small and medium-sized business ("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.

Concentration Risk Disclosure

Concentration of Credit Risk

The Company did not have a single customer that represented 10% or more of its consolidated revenues for the three and nine months ended September 30, 2023 and 2022 or 10% or more of its consolidated net trade receivables at September 30, 2023 and December 31, 2022, respectively.

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 September 30,		Nine Months Ended September 30,
	2023	2022	2023	2022
	(in thousands)
Basic weighted average shares outstanding	454,730	453,239	454,702	453,233
Effect of dilution:

Diluted weighted average shares outstanding	455,076	453,390	455,118	453,284
Weighted average shares excluded from diluted weighted average shares outstanding:

Share-based compensation awards whose performance metrics have not been achieved	25,947	7,298	19,230	7,481

(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 September 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 $174,998 and $123,880 as of September 30, 2023 and December 31, 2022, respectively.

Summary of Debt Maturities

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 September 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 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.

The following represents the location of the assets and liabilities associated with the Company's derivative instruments within the consolidated balance sheets:

(b)Amended rates effective July 17, 2023.

In April 2023, Lightpath entered into an interest rate swap contract, effective June 2023 on a notional amount of $180,000, whereby Lightpath pays interest of 3.523% through December 2026 and receives interest based on one-month SOFR. This swap contract is also not designated as a hedge for accounting purposes. Accordingly, this contract is carried at its fair market value on our consolidated balance sheet, with changes in fair value reflected in the consolidated statements of operations.

FAIR VALUE MEASUREMENT

9 Months Ended

Sep. 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 Hierarchy	September 30, 2023		December 31, 2022
Assets:
Money market funds	Level I	$	106,976	$	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	187,313		185,622
Liabilities:
Contingent consideration related to acquisition	Level III	1,947		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 September 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:

		September 30, 2023				December 31, 2022
	Fair Value Hierarchy	Carrying Amount (a)		Estimated Fair Value		Carrying Amount (a)		Estimated Fair Value
Credit facility debt	Level II	$	8,297,765	$	8,367,816	$	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	9,078,516		7,307,125		8,081,489		6,154,075
Senior notes	Level II	7,331,786		4,475,800		7,324,238		4,531,300
Notes payable and supply chain financing	Level II	175,276		175,276		127,635		127,608
		$	24,883,343	$	20,326,017	$	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.

The fair value estimates related to the Company's debt instruments presented above are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgments and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

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 nine months ended September 30, 2023, the Company 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 primarily due to the impact of certain non-deductible expenses, state tax expense, and tax deficiencies on share-based compensation.

For the three and nine months ended September 30, 2022, the Company recorded a tax expense of $35,827 and $152,563 on pre-tax income of $133,448 and $565,865, 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.

(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 canceled in connection with the Company's stock option exchange program discussed below.

As of September 30, 2023, the total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of approximately 2.71 years.

In January 2023, the Company 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 ten dollars of DCAs for every seven eligible options tendered. In connection with the Exchange Offer, the Company 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, the Company will recognize the unamortized compensation cost related to the canceled 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

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.
