NOTE 1. DESCRIPTION OF BUSINESS AND RELATED MATTERS

The Company and Related Matters

Optimum Communications, Inc. ("Optimum Communications") was incorporated in Delaware on September 14, 2015. Optimum Communications 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.

Optimum Communications, through CSC Holdings, LLC (a wholly-owned subsidiary of Cablevision) and its consolidated subsidiaries ("CSC Holdings," and collectively with Optimum Communications, the "Company", "we", "us" and "our"), principally delivers broadband, video, and telephony services to residential and business customers, as well as proprietary content and advertising services in the United States. We market our residential services under the Optimum brand and provide enterprise services under the Lightpath and Optimum Business brands. In addition, we offer a full service mobile offering to consumers across our footprint. As these businesses are managed on a consolidated basis, we classify our operations inone segment.

The accompanying consolidated financial statements ("consolidated financial statements") of Optimum Communications include the accounts of Optimum Communications 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. The consolidated balance sheets and statements of operations of Optimum Communications are essentially identical to the consolidated balance sheets and statements of operations of CSC Holdings, except for the assets and liabilities and results of operations associated with the wholly-owned subsidiary of Optimum Communications that provides insurance coverage to CSC Holdings ("Captive"), as well as additional cash and deferred tax liabilities at Optimum Communications. Additionally, CSC Holdings and its subsidiaries have certain intercompany receivables from and payables to Optimum Communications.

The combined notes to the consolidated financial statements relate to the Company, which, except as noted, are essentially identical for Optimum Communications and CSC Holdings. All significant intercompany transactions and balances between Optimum Communications and its respective consolidated subsidiaries are eliminated in Optimum Communications' consolidated financial statements. All significant intercompany transactions and balances between CSC Holdings and its respective consolidated subsidiaries are eliminated in CSC Holdings' consolidated financial statements. Intercompany transactions between Optimum Communications and CSC Holdings are not eliminated in the CSC Holdings consolidated financial statements, but are eliminated in the Optimum Communications consolidated financial statements.

The financial statements of CSC Holdings are included herein as supplemental information as CSC Holdings is not a Securities and Exchange Commission 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 our Annual Report on Form 10-K for the year ended December 31, 2025.

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, 2026.

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.

Going Concern

The consolidated financial statements have been prepared in accordance with generally accepted accounting principles on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, we have evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the financial statements are issued.

As reflected on the consolidated financial statements, as of March 31, 2026, we had cash and cash equivalents of $1,048,634, and we had principal amounts of debt of $4,130,000 maturing in April 2027 and $2,125,000 maturing in July 2027. Our ability to address these maturities depends on our ability to successfully refinance, restructure or otherwise extend such indebtedness or to raise additional capital to repay the indebtedness.

Because we do not currently have committed financing or cash and cash equivalents combined with projected future cash flows sufficient to satisfy the foregoing debt maturities arising within one year after the date these consolidated financial statements are issued, substantial doubt exists about our ability to continue as a going concern within one year after the date these consolidated financial statements are issued. While management is pursuing efforts to refinance or restructure the Company’s debt, or to raise additional capital sufficient to satisfy these debt maturities, there is no assurance these efforts will be successful.

The consolidated financial statements do not include any adjustments to the amount and classification of assets and liabilities that may be necessary should we not continue as a going concern.

NOTE 3. ACCOUNTING STANDARDS

Recently Issued But Not Yet Adopted Accounting Pronouncements

ASU No. 2025-11, Interim Reporting (Topic 270) —Narrow-Scope Improvements

In December 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The update is intended to improve the navigability of interim reporting guidance and clarify the required disclosures for interim periods. Key amendments include the establishment of a comprehensive list of required interim disclosures within Topic 270 and the introduction of a disclosure principle requiring an entity to disclose events occurring since the most recent annual reporting period that have a material impact on the entity.

The amendments also clarify the form and content requirements for condensed financial statements, including specific significance thresholds for financial statement captions. The ASU becomes effective for us for interim periods beginning January 1, 2028, with early adoption permitted. We are currently evaluating the impact that the adoption of this guidance will have on our consolidated financial statements and related disclosures.

ASU No. 2025-06 Intangibles—Goodwill and Other—Internal-Use Software

In September 2025, the FASB issued ASU 2025-06 Intangibles—Goodwill and Other—Internal-Use Software related to accounting for internal-use software costs. The amendments in this update improve the operability of the guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods. ASU 2025-06 becomes effective for us on January 1, 2028, though early adoption is permitted. We are currently evaluating the impact of adopting ASU 2025-06 on our consolidated financial statements and related disclosures.

ASU No. 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures

In November 2024, the FASB issued ASU No. 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, which requires disaggregated disclosures of certain categories of expenses on an annual and interim basis. ASU 2024-03 becomes effective for us for annual reporting periods beginning January 1, 2027, and interim reporting periods beginning January 1, 2028. We are currently evaluating the impact of adopting

ASU 2024-03 on our consolidated financial statements and related disclosures, but we expect the adoption will result in additional disaggregation of expense captions within our footnote disclosures.

NOTE 4. REVENUE

The following table presents the composition of revenue:

We are assessed non-income related taxes by governmental authorities, including franchising authorities (generally under multi-year agreements), and collect such taxes from our customers. In instances where the tax is being assessed directly on us, amounts paid to the governmental authorities are recorded as programming and other direct costs and amounts received from the customers are recorded as revenue. For the three months ended March 31, 2026 and 2025, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $49,247 and $51,570, respectively.

Customer Contract Costs

Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheet and totaled $20,578 and $21,397 as of March 31, 2026 and December 31, 2025, 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 tofive years, and services may only be terminated in accordance with the contractual terms.

Concentration of Credit Risk

We did not have a single customer that represented 10% or more of our consolidated revenues for the three months ended March 31, 2026 and 2025 or 10% or more of our consolidated net trade receivables at March 31, 2026 and December 31, 2025, respectively.

NOTE 5. NET INCOME (LOSS) PER SHARE

Basic net income (loss) per common share attributable to Optimum Communications stockholders is computed by dividing net income (loss) attributable to Optimum Communications stockholders by the weighted average number of common shares outstanding during the period. Diluted income per common share attributable to Optimum Communications 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. In periods with reported net losses attributable to Optimum Communications stockholders, share-based awards are anti-dilutive and excluded from the calculation of diluted loss per share.

Net income (loss) per membership unit for CSC Holdings is not presented since CSC Holdings is a limited liability company and a wholly-owned subsidiary of Optimum Communications.

NOTE 6. SUPPLEMENTAL CASH FLOW INFORMATION

Our non-cash investing and financing activities and other supplemental data were as follows:

Reconciliation of cash, cash equivalents and restricted cash :

NOTE 7. RESTRUCTURING, IMPAIRMENTS AND OTHER OPERATING ITEMS

Our restructuring, impairments and other operating items are comprised of the following:

(a)See Note 8 for a discussion of the impairment charge related to our indefinite-lived cable franchise rights.

(b)Amounts reflect estimated amounts for certain legal matters, including adjustments to these estimates, and costs to early terminate contracts with vendors.

NOTE 8. GOODWILL AND INTANGIBLE ASSETS

Our amortizable intangible assets primarily consist of customer relationships acquired pursuant to business combinations and represent the value of the business relationship with those customers.

The following table summarizes information relating to our acquired amortizable intangible assets:

Amortization expense for the three months ended March 31, 2026 and 2025 aggregated $61,575 and $74,070, respectively.

The carrying amount of indefinite-lived cable television franchises and goodwill is presented below:

Impairment Tests

Goodwill and the value of indefinite-lived cable franchises acquired in business combinations are not amortized. Rather, such assets are tested for impairment annually as of October 1, or whenever events or changes in circumstances indicate that it is more likely than not that the assets may be impaired. A deterioration in the Company’s operating performance, projected future performance or broader macro-economic conditions could be a triggering event that would require testing and may result in an impairment charge prior to the annual testing date.

During the three months ended March 31, 2026, we updated our annual long-term plan, which reflected a decline in estimated future cash flows. Management concluded that this was a triggering event and a quantitative impairment test of our indefinite-lived cable franchise rights and goodwill was performed as of March 31, 2026.

As a result of our quantitative impairment test, we recorded a non-cash impairment charge of $2,700,000 related to our indefinite-lived cable franchise rights for the three months ended March 31, 2026. These intangible assets represent contractual rights to operate cable systems in specific geographic areas. The decline in the estimated fair value of our indefinite-lived franchise rights was attributable to updated long-term financial projections, that reflected a reduction in estimated future cash flows as a result of increased investment in our fiber network and the sustained competitive environment and macroeconomic conditions. The impairment analysis was conducted using a discounted cash flow methodology, which incorporated updated projections of future cash flows, growth rates, and discount rates consistent with current market assumptions. If we experience a significant shortfall in cash flows from new customers, then we may incur future non-cash impairment charges on our indefinite-lived cable franchise rights. This charge is included in "Restructuring, impairments and other operating items" in the consolidated statement of operations and did not impact our cash flow or liquidity. As the carrying value of our franchise rights represent fair value, any reduction in the fair value of these rights would result in an additional impairment charge. A hypothetical

10% reduction in the fair value of our franchise rights would result in an additional impairment charge of approximately $890,000.

In connection with the quantitative test performed on goodwill, we concluded the estimated fair value of our Telecommunications reporting unit exceeded its carrying value and no impairment was recorded.

NOTE 9. DEBT

The following table provides details of our outstanding debt:

(a)The carrying amount is net of the unamortized deferred financing costs and discounts/premiums, as applicable.

(b)At March 31, 2026, $200,261 of the revolving credit facility was restricted for certain letters of credit issued on our behalf and $149,739 of the $2,475,000 facility was undrawn and available, subject to covenant limitations. The revolving credit facility bears interest at a rate of Secured Overnight Financing Rate ("SOFR") (plus a credit adjustment spread of 0.10%) plus 2.25% per annum.

(c)Incremental Term Loan B-5 requires quarterly installments of $7,500 and bore interest at a rate equal to Synthetic USD London Interbank Offered Rate ("LIBOR") plus 2.50% per annum through March 31, 2025. Thereafter, we are required to pay interest at a rate equal to the alternate base rate (“ABR”), plus the applicable margin, where the ABR is the greater of (x) prime rate or (y) the federal funds effective rate plus 50 basis points, and the applicable margin for any ABR loan is 1.50% per annum.

(d)At March 31, 2026, $6,088 of a $100,000 Variable Funding Note available to Lightpath was restricted for certain letters of credit issued on its behalf. The remaining $93,912 was undrawn and available, subject to covenant limitations.

(e)Repaid with proceeds from the Lightpath Secured Fiber Network Revenue Notes (see discussion below).

For financing purposes, we have three debt silos: CSC Holdings, the UnSub Group (defined below) and Lightpath. The CSC Holdings silo is structured as a restricted group (the "CSC Holdings Restricted Group") and an unrestricted group, which includes certain designated subsidiaries. The CSC Holdings Restricted Group is comprised of CSC Holdings and its wholly-owned operating subsidiaries, excluding Lightpath and certain of its designated subsidiaries, Cablevision Litchfield, LLC ("Cablevision Litchfield"), CSC Optimum Holdings, LLC ("CSC Optimum") and certain subsidiaries of CSC Holdings designated as "unrestricted subsidiaries" for the purposes of the CSC Holdings silo (collectively, the "UnSub Group"). The CSC Holdings Restricted Group is subject to the covenants and restrictions of CSC Holdings' credit facility and indentures governing the notes issued by CSC Holdings. The Lightpath silo includes substantially all of Lightpath's operating subsidiaries which are subject to the covenants and restrictions of the secured fiber network revenue notes issued by Lightpath. The UnSub Group is subject to the covenants and restrictions of the UnSub Group Facility.

UnSub Group Credit Facility

On November 25, 2025, Cablevision Litchfield and CSC Optimum, each an indirect wholly-owned subsidiary of the Company, entered into a Credit Agreement (the "Initial UnSub Group Credit Facility"), by and among Cablevision Litchfield and CSC Optimum, each as a borrower, the guarantors party thereto, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent and collateral agent. The Initial UnSub Group Credit Facility provided for, among other things, initial term loans in an aggregate principal amount of $2,000,000 (the "Initial UnSub Group Credit Facility Loans"). The Initial UnSub Group Credit Facility Loans were used to repay in full the Incremental Term Loan B-7 under the CSC Credit Facilities.

On January 12, 2026, Cablevision Litchfield and CSC Optimum entered into an Amended and Restated Credit Agreement (the "A&R UnSub Credit Agreement"), by and among Cablevision Litchfield and CSC Optimum, each as a borrower, the guarantors party thereto, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent and collateral agent. The A&R UnSub Credit Agreement provided for, among other things, incremental term loans in an aggregate principal amount of $1,100,000 (the "Incremental UnSub Credit Facility Loans" and, together with the Initial UnSub Group Credit Facility Loans, the "Credit Facility Loans"). Effective February 11, 2026, Cablevision Funding joined the A&R UnSub Credit Agreement as borrower under solely the Incremental UnSub Credit Facility Loans. The A&R UnSub Credit Agreement amended and restated the Initial UnSub Group Credit Facility in its entirety (as so amended and restated, the "UnSub Group Credit Facility"). The Incremental UnSub Credit Facility Loans were used to repay Receivables Facility Loan and Security Agreement, dated as of July 16, 2025 (the “NYC ABS Loan and Security Agreement”), by and among Cablevision Funding LLC, Cablevision SPE Guarantor LLC, the other loan parties party thereto from time to time, each of the financial institutions from time to time party thereto as lenders, Alter Domus (US) LLC, as administrative agent, Citibank, N.A., as Account Bank (as defined therein), Citibank, N.A., as collateral agent, and Goldman Sachs Bank USA and TPG Angelo Gordon, as structuring agents, and pay certain costs associated with the transactions. The remaining proceeds are being used for other general corporate purposes. The UnSub Group Credit Facility Loans will (i) mature on November 25, 2028, (ii) accrue interest at a fixed rate per annum equal to 9.0%, and (iii) not amortize.

Lightpath Secured Fiber Network Revenue Notes

On March 3, 2026, Cablevision Lightpath LLC ("Lightpath") refinanced all of its outstanding indebtedness through an asset‑backed securitization ("ABS") transaction. In connection with the refinancing, Lightpath repaid in full and terminated all prior debt facilities, including its senior notes due 2028, senior secured notes due 2027 and its term loan facility balance previously outstanding. Upon repayment, all liens and guarantees associated with this indebtedness were released and all commitments were terminated.

The refinancing was executed through the issuance by Lightpath Fiber Issuer LLC (the “Issuer”) of Secured Fiber Network Revenue Notes, Series 2026‑1 (the "Series 2026‑1 Notes"). The Issuer is a newly formed, wholly owned and bankruptcy-remote indirect subsidiary of Lightpath.

The notes consist of $1,527,000 in aggregate principal amount of Series 2026-1, Class A-2 Notes (the "Class A-2 Notes") and $130,000 in aggregate principal amount of Series 2026-1, Class B Notes (the "Class B Notes"). The Class A-2 Notes bear interest at a rate of 5.597%, and the Class B Notes bear interest at a rate of 5.890%. Deferred financing costs incurred with the issuance of these notes amounted to $25,281.

In addition to the Series 2026-1 Notes, the Issuer also entered into a Variable Funding Note ("VFN") facility with a revolving commitment of up to $100,000 (expandable to $300,000 subject to conditions), and a Liquidity Funding Note facility of up to $45,000, designed to support working capital and liquidity needs within the ABS structure.

Proceeds from the issuance of the Series 2026-1 Notes were used to repay all outstanding Lightpath indebtedness existing prior to the refinancing, fund required reserve accounts, including a liquidity reserve account, pay transaction fees, expenses, and other costs associated with the ABS issuance and general corporate purposes.

The Series 2026‑1 Term Notes are secured by substantially all of the fiber network assets and related customer agreements of Lightpath's asset‑owning securitized subsidiaries, which collectively serve as collateral for the securitization. The Notes are non‑recourse to Lightpath and its non‑securitized subsidiaries, other than through the guarantees provided within the ABS structure by the asset‑owning entities and Lightpath Fiber Guarantor LLC.

Interest on the Series 2026-1 Notes is fixed, payable monthly in arrears, beginning April 2026, and mature in March 2031. The securitization includes customary cash‑flow waterfalls, reserve accounts, financial covenants—including a senior debt service coverage ratio—and provisions for optional and mandatory prepayments.

Following this refinancing, Lightpath's revolving credit facility is no longer available, and borrowings will occur within the ABS structure through the Variable Funding Notes, subject to meeting required borrowing conditions. As of March 31, 2026, $6,088 of the available VFN facility was restricted for certain letters of credit issued on Lightpath's behalf.

Debt Compliance

As of March 31, 2026, CSC Holdings was in compliance with applicable financial covenants under its credit facility and with applicable financial covenants under each respective indenture by which the senior guaranteed notes and senior notes were issued. Lightpath Fiber Issuer LLC was in compliance with applicable covenants under the Secured Fiber Network Revenue Notes. The UnSub Group Credit Facility does not provide for any financial covenants.

Loss on Extinguishment of Debt and the Write-off of Deferred Financing Costs

The following table provides a summary of the loss on extinguishment of debt and the write-off of deferred financing costs recorded:

Summary of Debt Maturities

The future principal payments under our various debt obligations outstanding as of March 31, 2026, excluding finance lease obligations, are as follows:

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 our financial assets and financial liabilities that are measured at fair value on a recurring basis and their classification under the fair value hierarchy:

(a)Money market funds at CSC Holdings amounted to $630,016 and $929,604 as of March 31, 2026 and December 31, 2025, respectively.

Our money market funds which are classified as cash equivalents are classified within Level I of the fair value hierarchy because they are valued using quoted market prices.

The interest rate swap contracts on our consolidated balance sheets are valued using market-based inputs to valuation models. These valuation models require a variety of inputs, including contractual terms, market prices, yield curves, and measures of volatility. When appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads and credit risk considerations. Such adjustments are generally based on available market evidence. Since model inputs can generally be verified and do not involve significant management judgment, we have concluded that these instruments should be classified within Level II of the fair value hierarchy.

The fair value of the contingent consideration as of March 31, 2026 and December 31, 2025 related to certain acquisitions was determined using a probability assessment of the contingent payment for the respective periods.

Fair Value of Financial Instruments

The following methods and assumptions were used to estimate fair value of each class of financial instruments for which it is practicable to estimate:

Credit Facility Debt, Senior Notes, Senior Guaranteed Notes, Senior Secured Notes and Secured Fiber Network Revenue Notes

The fair values of each of our debt instruments are based on quoted market prices of these instruments.

UnSub Group Credit Facility and NYC ABS Receivables Facility Loan

The fair value of the UnSub Group Credit Facility and NYC ABS receivables facility loan are based on Level 3 inputs, as these facilities are not actively traded and were determined using a discounted cash flow ("DCF") model. This model estimates the present value of the expected future interest and principal payments under the terms of the UnSub Group Credit Facility and NYC ABS receivables facility loan.

The carrying values, estimated fair values, and classification under the fair value hierarchy of our financial instruments, excluding those that are carried at fair value in the accompanying consolidated balance sheets, are summarized below:

(a)Amounts are net of unamortized deferred financing costs and discounts/premiums.

The table above excludes the estimated fair value of CSC Holding's note payable to Captive of $80,500 and $82,500 as of March 31, 2026 and December 31, 2025, as it is eliminated in the Optimum Communications consolidated financial statements (see Note 13). The carrying value of the note payable approximates fair value due to its short-term maturity (less than one year).

The fair value estimates related to our 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

We use an estimated annual effective tax rate ("AETR") to measure the income tax expense or benefit recognized on a year-to-date basis in an interim period. In addition, certain items included in income tax expense as well as the tax impact of certain items included in pretax income must be treated as discrete items. The income tax expense or benefit associated with these discrete items is fully recognized in the interim period in which the items occur.

Optimum Communications

For the three months ended March 31, 2026, we recorded a tax benefit of $45,108 on pre-tax loss of $2,922,084, resulting in an effective tax rate that was lower than the U.S. statutory tax rate. The lower rate is primarily due to the nonrecognition for tax purposes of the intangible impairment charge.

For the three months ended March 31, 2025, we recorded a tax benefit of $15,964 on pre-tax loss of $87,235. The effective tax rate was lower than the U.S. statutory tax rate primarily due to the increase in tax deficiencies on share-based compensation.

CSC Holdings

For the three months ended March 31, 2026, we recorded a tax benefit of $45,749 on pre-tax loss of $2,925,136, resulting in an effective tax rate that was lower than the U.S. statutory tax rate. The lower rate is primarily due to the nonrecognition for tax purposes of the intangible impairment charge.

For the three months ended March 31, 2025, we recorded a tax benefit of $16,452 on pre-tax loss of $90,169. The effective tax rate was lower than the U.S. statutory rate primarily due to the increase in tax deficiencies on share-based compensation.

NOTE 12. SHARE-BASED COMPENSATION AND LONG-TERM INCENTIVE AWARDS

Share-based Compensation

The following table presents share-based compensation expense (benefit) and unrecognized compensation cost:

Restricted Share Units

The following table summarizes activity related to restricted share units granted to our employees:

Cash Denominated Performance Awards

The following table summarizes activity related to cash denominated performance award granted to our employees:

The cash denominated performance awards cliff vest in three years. The payout of these awards can range from 0% to 200% of the target value based on our achievement of certain revenue and Adjusted EBITDA targets during a three year performance period. These awards will be settled in shares of our Class A common stock, or cash, at our option.

Lightpath Plan Awards

As of March 31, 2026,581,234 Class A-1 management incentive units and 307,670 Class A-2 management incentive units ("Award Units") granted to certain employees of Lightpath were outstanding. Vested units will be redeemed upon a partial exit, a change in control or the completion of an initial public offering, as defined in the Lightpath Holdings LLC agreement. The grant date fair value of the Award Units outstanding aggregated $31,369 and will be expensed in the period in which a partial exit or a liquidity event is consummated.

Long-term Incentive Awards

Deferred Cash Award

In February 2026, certain employees were granted a time-based Deferred Cash Award (“DCA”). This award vests ratably over three years with one-third payable in cash in each of December 2026, December 2027, and December 2028. The amount granted under the DCA totaled $39,010. As of March 31, 2026, we recorded compensation cost related to these awards of $890.

NOTE 13. AFFILIATE AND RELATED PARTY TRANSACTIONS

Affiliate and Related Party Transactions

Optimum Communications is controlled by Patrick Drahi through Next Alt who also controls Altice Europe and other entities.

As the transactions discussed below were conducted between entities under common control by Mr. Drahi, amounts charged for certain services may not have represented amounts that might have been received or incurred if the transactions were based upon arm's length negotiations.

The following table summarizes the revenue and expenses related to services provided to or received from affiliates and related parties:

Amounts due to affiliates presented in the table above and included in other current liabilities in the accompanying balance sheets relate to the purchase of equipment, customer care services, and advertising services, as well as reimbursement for payments made on our behalf.

CSC Holdings Transactions with Optimum Communications

During the three months ended March 31, 2025, CSC Holdings made cash equity distribution payments to its parent of $8,547.

The following table provides intercompany balances and activity between CSC Holdings and Optimum Communications as of March 31, 2026 and for the year ended December 31, 2025:

In December 2025, we transferred our interest in i24 NEWS to an entity under common control, for cash consideration of $1,000. In addition, we agreed to reimburse the buyer for certain liabilities incurred by the buyer between the transfer date and March 31, 2026, not to exceed $5,000. The accompanying statement of stockholders' deficiency reflects distributions aggregating $3,446 related to this reimbursement.

NOTE 14. COMMITMENTS AND CONTINGENCIES

Legal Matters

On December 7, 2023, Warner Records Inc., Sony Music Publishing (US) LLC and a number of other purported copyright holders (collectively, the “Warner Plaintiffs”) filed a complaint in the U.S. District Court for the Eastern District of Texas (the “Warner Matter”), alleging that certain of our Internet subscribers directly infringed over 10,700 of the Warner Plaintiffs’ copyrighted works. The Warner Plaintiffs seek to hold us liable for claims of contributory infringement of copyright and vicarious copyright infringement. The Warner Plaintiffs also claim that our alleged secondary infringement was willful and seek substantial statutory damages. On July 15, 2025, the Court issued an order staying the case, including the trial scheduled to commence in September 2025, pending the Supreme Court of the United States’ decision in Cox Communications, Inc. v. Sony Music Entertainment. On April 22, 2026, the parties filed a joint stipulation of dismissal together with a proposed order dismissing the action, and on April 29, 2026, the Court dismissed the case.

On September 10, 2024, United States Technologies Communication Corp. d/b/a Netceed filed suit in the New York Supreme Court, New York County. Plaintiff asserts claims for declaratory judgment, breach of contract, and breach of the implied covenant of good faith and fair dealing for alleged violations of the parties’ services and sales agreements, and seeks compensatory damages, as set forth in the complaint. We deny the claims and intend to vigorously defend the lawsuit. On November 21, 2024, we filed a motion to dismiss in part plaintiff’s complaint, and on May 15, 2025, the Court issued a decision and order on the Company’s motion to dismiss, and dismissed certain causes of action. On June 12, 2025, the Company filed its answer, affirmative defenses, and counterclaim. Although the outcome of this matter cannot be predicted and the impact of the final resolution on our results of operations in a subsequent reporting period is not known, management does not believe that the resolution of the matter will have a material adverse effect on our operations or financial position or our ability to meet our financial obligations as they become due.

We also receive notices from third parties, and in some cases we are named as a defendant in lawsuits, claiming infringement of various patents or copyrights relating to various aspects of our businesses. In certain of these cases other industry participants are also defendants, and in certain of these cases we expect that some or all potential liability would be the responsibility of our vendors pursuant to applicable contractual indemnification provisions. In the event that we are found to infringe on any patent or other intellectual property rights, we may be subject to substantial damages or an injunction that could require us or our vendors to modify certain products and services we offer to our subscribers, as well as enter into royalty or license agreements with respect to the patents at issue. We are also party to various other lawsuits, disputes and investigations arising in the ordinary course of our business, some of which may involve claims for substantial damages, fines or penalties. Although the outcome of these matters cannot be predicted and the impact of the final resolution of these matters on our results of operations in a particular subsequent reporting period is not known, management does not believe that the resolution of these matters, individually, will have a material adverse effect on our operations or financial position or our ability to meet our financial obligations as they become due, but they could be material to our consolidated results of operations or cash flows for any one period.

NOTE 15. SEGMENT REPORTING

We principally deliver broadband, video, telephony and mobile services to residential and business customers, as well as proprietary content and advertising services in the United States. Our connectivity services are provided through a converged fixed and mobile network and key operating activities and resource allocation decisions are managed centrally. Our chief executive officer is the chief operating decision maker ("CODM"). Our CODM assesses performance and decides how to allocate resources based on our consolidated statements of operations. Our CODM manages the business on a consolidated basis such that we have a single operating segment. Our segment performance measure is consolidated net income (loss). The measure of segment assets is the Company's total consolidated assets which are reflected on our balance sheets.

The following table presents significant expenses that are not separately presented on the statements of operations that are reviewed by the CODM.

(a)Other direct costs include interconnection, call completion, circuit and transport fees paid to other telecommunication companies for the transport and termination of voice and data services. These costs also include franchise fees which are payable to the state governments and local municipalities where we operate. Additionally, these costs include the cost of media for advertising spots sold, the cost of mobile devices sold to our customers and direct costs of providing mobile services.

(b)Other operating expenses include costs related to our call center operations that handle customer inquiries and billing and collection activities, costs related to our information technology systems, costs related to our news and advertising business, as well as our Lightpath business, and various other operating costs such as share-based compensation, corporate overhead and facilities.

(c)Other operating expenses for CSC Holdings for the three months ended March 31, 2026 and 2025 amounted to $661,970 and $699,705, respectively, and include additional costs of $1,767 and $1,519 respectively, that were eliminated at Optimum Communications.

(d)Certain reclassifications have been made to the 2025 amounts to conform to the 2026 presentation.

NOTE 16. SUPPLEMENTAL INFORMATION

For financing purposes, CSC Holdings is structured as a "Restricted Group" and an "Unrestricted Group." The Restricted Group was historically comprised of CSC Holdings and substantially all of its wholly-owned operating subsidiaries. These Restricted Group subsidiaries are subject to the covenants and restrictions of the CSC Holdings' Credit Facility and the indentures governing the notes issued by CSC Holdings. The Unrestricted Group includes certain designated subsidiaries and investments (the "Unrestricted Group") which are not subject to such covenants.

The composition of the Restricted Group was modified as a result of the NYC ABS transaction in July 2025 and an amendment to the CSC Holdings' Credit Facility in November 2025, which resulted in certain subsidiaries being re-designated as unrestricted subsidiaries. The Company’s financial information is now presented to reflect the current composition of the Restricted Group following these re-designations.

The financial information set forth below reflects the financial condition and results of operations of the Restricted Group, presented separately from the financial condition and results of operations of the Unrestricted Group. To provide a meaningful comparison of the current composition of the Restricted Group, the financial information as of and for the three months ended March 31, 2026 and 2025 is presented on a pro forma basis as if the July 2025 designation and the November 2025 designation had, in each case, occurred on January 1, 2025.

(a)Includes an impairment charge related to our indefinite-lived cable franchise rights of $1,618,489 for the Restricted Group and $1,081,511 for the Unrestricted Group.
