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 Systems Corporation) 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.

Cash Tender Offer

In July 2026, in accordance with the terms and conditions of a tender offer (the "Tender Offer") by CSC Investments II LLC (which was subsequently renamed Optimum CSC LLC ("Optimum CSC")), an indirect wholly owned subsidiary of Optimum Communications, to purchase shares of Class A common stock of Optimum Communications from unaffiliated stockholders at a purchase price of $2.50 per share, Optimum CSC acquired 120,000,000 shares for an aggregate purchase price of $300,000, excluding fees and expenses. As required by U.S. generally accepted accounting principles ("GAAP"), we recognized an expense of $160,800 based on the closing price of the Company's common stock on the transaction date. This expense is included in "Restructuring, impairments and other operating items" in the accompanying consolidated statement of operations. The shares held by Optimum CSC are reflected as treasury shares on the consolidated balance sheet of Optimum Communications.

NOTE 2. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with 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, as amended by Amendment No. 1 on Form 10-K/A.

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 September 30, 2026, we had cash and cash equivalents of $1,100,796, and we had principal amounts of debt of $4,115,000 maturing in April 2027 and $2,225,000 maturing in July 2027. Our ability to address these maturities depends on our ability to successfully restructure, refinance 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 restructure or refinance 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 and nine months ended September 30, 2026, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $48,942 and $146,514, respectively. For the three and nine months ended September 30, 2025, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $49,905 and $152,060, respectively.

Customer Contract Costs

Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheet and totaled $22,015 and $21,397 as of September 30, 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. We have elected the practical expedient to omit disclosure of the amount of the transaction price allocated to remaining performance obligations for contracts with an original expected contract length of one year or less. As of September 30, 2026, total transaction price allocated to performance obligations that were unsatisfied or partially unsatisfied for contracts with an original expected length of more than one year was approximately 37% of annualized Business Services and Wholesale revenue. We expect to recognize the majority of this revenue over the next three years and the rest over the remaining performance obligation period.

Concentration of Credit Risk

We did not have a single customer that represented 10% or more of our consolidated revenues for the three and nine months ended September 30, 2026 and 2025 or 10% or more of our consolidated net trade receivables at September 30, 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.

For the three and nine months ended September 30, 2026, and 2025, we were in a net loss position. Accordingly, the inclusion of shares of incremental potential common stock from options, restricted stock units, and cash denominated performance awards were excluded from the computation of diluted loss per share because their effect would have been anti-dilutive. As a result, basic and diluted loss per share are identical for the periods presented.

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)In July 2025, we completed the sale of certain tower assets for $59,908 and recorded a gain of $55,114. In connection with the sale, we entered into a master license agreement with the buyer pursuant to which we maintain access to space on certain of those towers for an initial term of five years.

(b)Includes costs related to our workforce management initiatives, including costs related to a voluntary retirement program during the three and nine months ended September 30, 2025.

(c)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 and nine months ended September 30, 2026 aggregated $49,791 and $170,772, respectively, and $63,023 and $209,412 for the three and nine months ended September 30, 2025.

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, which was deemed to be a triggering event for a quantitative impairment test of our indefinite-lived cable franchise rights and goodwill. Subsequently, during the three months ended September 30, 2026, a decline in industry valuation multiples and other factors were similarly deemed triggering events for a quantitative impairment test of these intangibles. The results of these quantitative tests in the first and third quarter are discussed below:

Indefinite-lived cable franchise rights - March 31, 2026

We recorded a non-cash impairment charge of $2,700,000 related to our indefinite-lived cable franchise rights during 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 cable 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.

Indefinite-lived cable franchise rights - September 30, 2026

We recorded a non-cash impairment charge of $3,200,000 related to our indefinite-lived cable franchise rights during the three months ended September 30, 2026. The decline in estimated fair value of our indefinite-lived cable franchise rights was primarily attributable to (i) an increase in discount rate of 3% to reflect current interest rates and market-participant assumptions, including changes in the perceived risk associated with the projected cash flows and (ii) a decrease in the long-term growth rate of 1% to reflect management's updated expectation of the anticipated impact of the sustained competitive environment on the long-term cash flow growth associated with our indefinite-lived cable franchise rights.

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. These charges are included in "Restructuring, impairments and other operating items" in the consolidated statements 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 $570,000.

The impairment charges recorded for our indefinite-lived cable franchise rights during the three months ended March 31, 2026, and September 30, 2026, represent nonrecurring fair value measurements categorized within Level 3 of the fair value hierarchy under ASC 820. Fair value was determined using an income approach based on a discounted cash flow methodology, which relies on significant unobservable inputs (Level 3). Significant unobservable inputs utilized in these measurements included long-term financial projections of future operating cash flows, discount rates reflecting current weighted-average cost of capital, market risk premiums and long-term terminal growth rates.

Goodwill - March 31, 2026 and September 30, 2026

In connection with the quantitative goodwill impairment tests performed in March 2026 and September 2026, we concluded the estimated fair value of our Telecommunications reporting unit exceeded its carrying value and no impairment was recorded.

We estimated the fair value of our reporting unit by considering both (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which is based on the expected normalized cash flows of the reporting unit following the discrete projection period, and (ii) a market approach, which includes the use of market multiples of publicly-traded companies whose services are comparable to ours. Significant judgments in estimating the fair value of our reporting units include cash flow projections and the selection of the discount rate.

The estimates and assumptions utilized in estimating the fair value of our Telecommunications reporting unit could have a significant impact on whether and to what extent an impairment charge is recognized. Fair value estimates are made at a specific point in time, based on relevant information. These estimates are subjective in nature and involve uncertainties and matters of significant judgments. Changes in assumptions could significantly affect the estimates.

It is possible that in the future there may be changes in our estimates and assumptions, including the timing and amount of future cash flows, margins, growth rates, market participant assumptions, comparable benchmark companies and related multiples and discount rates, which could result in different fair value estimates. Significant and adverse changes to any one or more of the above-noted estimates and assumptions could result in an impairment charge in the future. As of September 30, 2026, a hypothetical 10% reduction in the business enterprise value of our Telecommunications reporting unit would result in an impairment charge of approximately $1,600,000.

NOTE 9. DEBT AND REDEEMABLE PREFERRED UNITS

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 September 30, 2026, $177,979 of the revolving credit facility was restricted for certain letters of credit issued on our behalf and $72,021 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 September 30, 2026, $6,288 of $100,000 Variable Funding Notes available to Lightpath was restricted for certain letters of credit issued on its behalf. The remaining $93,712 was undrawn, 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 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 comprised of CSC Holdings and its wholly-owned operating subsidiaries, excluding Lightpath and 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.

The obligations under the CSC Holdings Restricted Group Credit Facility are guaranteed on a senior secured basis by each material restricted subsidiary of CSC Holdings (other than certain excluded subsidiaries). The obligations under the CSC Holdings Restricted Group Credit Facility (including any guarantees thereof) are secured on a first priority basis, subject to permitted liens, by capital stock held by CSC Holdings and any guarantor in restricted subsidiaries of CSC Holdings, subject to certain exclusions and limitations. The obligations under the CSC Holdings Senior Guaranteed Notes are guaranteed on a senior unsecured basis by each restricted subsidiary of CSC Holdings that guarantees the obligations under the CSC Holdings Restricted Group Credit Facility.

UnSub Group Credit Facility

On November 25, 2025, the UnSub Group entered into a Credit Agreement (the "Initial UnSub Group Credit Facility") and as later amended or restated as described below, the “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 Holdings Restricted Group Credit Facility.

On January 12, 2026, the UnSub Group entered into an Amended and Restated Credit Agreement (the "A&R UnSub Group 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 Group Credit Agreement provided for, among other things, incremental term loans in an aggregate principal amount of $1,100,000 (the "Incremental UnSub Group Credit Facility Loans" and, together with the Initial UnSub Group Credit Facility Loans and the Second Incremental UnSub Group Credit Facility Loans (as defined below), the "UnSub Group Credit Facility Loans"). Effective February 11, 2026, Cablevision Funding joined the A&R UnSub Group Credit Agreement as borrower under solely the Incremental UnSub Group Credit Facility Loans. The A&R UnSub Group Credit Agreement amended and restated the Initial UnSub Group Credit Facility in its entirety. The Incremental UnSub Group 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 were used for other general corporate purposes. The UnSub Group Credit Facility Loans (i) mature on November 25, 2028, (ii) accrue interest at a fixed rate per annum equal to 9.0%, and (iii) do not amortize.

In May 2026, the UnSub Group entered into Amendment No. 1 to the Initial UnSub Group Credit Facility. The amendment established an "Applicable Premium" following certain CSC Holdings insolvency events, generally equal to the interest that would have accrued on affected term loans through maturity. It did not change the principal amount, lender commitments, interest rate, maturity, amortization, collateral or guarantees, financial covenants or reporting requirements. The fair value of this embedded derivative was not significant. The Company incurred customary consent, advisory and legal fees. In connection with this transaction, we incurred additional deferred financing costs of $15,500.

The UnSub Group entered into a Second Amended and Restated Credit Agreement, dated as of July 6, 2026 (the "Second A&R UnSub Group Credit Agreement"). The Second A&R UnSub Group Credit Agreement amended and restated the A&R UnSub Group Credit Agreement in its entirety, and provides for, among other things, an incremental term loan commitment in an aggregate principal amount of $250,000. The loans made pursuant to such incremental term loan commitment on July 6, 2026 (the "Second Incremental UnSub Group Credit Facility Loans") have terms which are substantially similar to those of the term loans that have been outstanding under the A&R UnSub Group Credit Agreement, which term loans will remain outstanding under the Second A&R UnSub Group Credit Agreement, and (i) mature on November 25, 2028, (ii) accrue interest at a fixed rate per annum equal to 9.0% and (iii) do not amortize. In connection with this transaction, we incurred additional deferred financing and original issue discount costs totaling $13,760. The proceeds were used for general corporate purposes.

The obligations under the UnSub Group Credit Facility are guaranteed on a senior secured basis by certain subsidiaries included in our UnSub Group (other than CSC TKR Intermediate, LLC, CSC TKR, LLC and their subsidiaries, which own and operate our New Jersey cable television systems), subject to certain limitations. The obligations under the UnSub Group Credit Facility are secured by a first-priority lien on substantially all of the assets of each borrower and guarantor thereunder, subject to certain exclusions and limitations.

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" and together with the Class A-2 Notes, the “Series 2026-1 Term 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 Term Notes, the Issuer also issued Variable Funding Notes ("VFN") with a revolving commitment of up to $100,000 (expandable to $300,000 subject to conditions), and Liquidity Funding Notes with a single draw commitment 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 Term 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. As of September 30, 2026, we had short-term restricted cash of $61,251 relating to these reserve accounts and other restricted cash accounts.

The Series 2026‑1 Term Notes are secured by the fiber network assets and related customer agreements owned by 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.

Interest on the Series 2026-1 Term 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 VFN, subject to meeting required borrowing conditions. As of September 30, 2026, $6,288 of the available VFN facility was restricted for certain letters of credit issued on Lightpath's behalf.

Debt Compliance

As of September 30, 2026, CSC Holdings was in compliance with applicable financial and nonfinancial covenants under its credit facility. Lightpath Fiber Issuer LLC was in compliance with applicable financial and nonfinancial covenants under the Secured Fiber Network Revenue Notes. The UnSub Group Credit Facility and the respective indentures by which the senior guaranteed notes and senior notes were issued do not provide for any financial covenants, but we were in compliance with nonfinancial covenants under this facility.

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 September 30, 2026, excluding finance lease obligations, are as follows:

Redeemable Preferred Unit Transactions

Private Placement of Redeemable Preferred Units

On May 29, 2026, Optimum CSC sold to certain institutional accredited investors newly issued Series A Preferred Units of Optimum CSC (the “Preferred Units”) having an initial stated value of $300,000 for an aggregate purchase price of $300,000 (the “Private Placement Transaction”).

Optimum CSC is an unrestricted subsidiary of CSC Holdings and a holding company for certain of CSC Holdings’ designated unrestricted subsidiaries, including the UnSub Group, certain other subsidiaries of CSC Holdings designated as “unrestricted subsidiaries” for the purposes of the debt agreements of CSC Holdings and CSC Holdings’ interest in Cablevision Lightpath LLC.

Proceeds from the Private Placement Transaction were used for general corporate purposes, including to finance the Tender Offer (as defined below) and pay transaction expenses.

The Preferred Units are perpetual preferred interests in Optimum CSC. Dividends are payable in cash or by compounding, at Optimum CSC’s option. Cumulative dividends accrue on the stated value of the Preferred Units and are payable quarterly at a rate of 13.0% per annum if paid in cash or 15.0% if compounded. The dividend rate may increase by 2.0% per annum upon the occurrence and during the continuance of certain triggering events.

The Preferred Units are redeemable by Optimum CSC at any time at a redemption price (the “Redemption Price”) equal to the greater of (i) 100% of the then-current stated value and (ii) the amount necessary to result in an applicable minimum MOIC (as described below), in each case, plus the aggregate amount of accumulated and unpaid dividends that have not yet been paid in cash or compounded up to, but excluding, the redemption date.

The applicable minimum MOIC (multiple on invested capital) is initially 1.25 x, increases to 1.50 x nine months after issuance or upon certain specified events, and increases to 2.50 x upon the earliest occurrence of specified non-consensual bankruptcy events involving CSC Holdings or certain of its material subsidiaries, the acceleration of indebtedness under certain CSC Holdings debt agreements, or the exercise of creditor remedies under such debt obligations following an event of default. Certain pre-arranged, pre-negotiated and pre-packaged Chapter 11 proceedings are excluded from the bankruptcy trigger. The fair value of this embedded derivative was not significant.

The Preferred Units are subject to mandatory redemption upon the occurrence of (i) a sale of all or substantially all of Optimum CSC and its subsidiaries, (ii) any insolvency, liquidation, dissolution or winding up of Optimum CSC or its material subsidiaries (but not a change of control or insolvency, liquidation, dissolution or winding up of Optimum Communications or its subsidiaries (other than Optimum CSC and its subsidiaries)) or (iii) a failure by Optimum CSC to comply with the requirements of a sale demand made by holders of a majority of any Preferred Units that remain outstanding following the eighth anniversary of the issue date.

The terms of the Preferred Units permit Optimum CSC and its subsidiaries to incur indebtedness, subject to compliance with a consolidated total net debt ratio (excluding the Preferred Units or any senior equity) of 4.50 x on a pro forma basis, and to incur senior or pari preferred equity subject to a consolidated total net debt and preferred equity ratio of 4.75 x on a pro forma basis (which ratios decrease to 4.00 x upon the occurrence of certain events) and certain other exceptions. In addition, upon the occurrence of certain triggering events, restrictions on specified payments or affiliate transactions will also apply.

Due to the existence of contingent redemption features that are not solely within the Company’s control, the Preferred Units are classified as temporary equity in the accompanying consolidated balance sheets. The carrying value is being accreted to the redemption value from the issue date through the eighth anniversary of the issue date, and is recognized within "Net income attributable to redeemable noncontrolling interests" on the consolidated statements of operations. If the Preferred Units are redeemed by the Company prior to December 31, 2028, the redemption value will exceed the carrying amount and additional expense will be recognized by the Company upon redemption, and that expense could be material.

Accretion of the Preferred Units’ redemption value aggregating $19,475 and $26,308 for the three and nine months ended September 30, 2026, and distributions reduce income available to common equity holders for purposes of earnings per share.

Private Exchange Transaction

On May 29, 2026, Optimum CSC entered into an exchange transaction (the “Private Exchange Transaction”) with Next Alt and its affiliate, Next Partner, L.P. (“Next Partner” and, together with Next Alt, the “Next Entities”), certain members of Optimum Communications' board of directors and executive management. In the Private Exchange Transaction, Optimum CSC issued additional Preferred Units having an initial stated value of $200,000 to Next Partner in exchange for 5,846,652 shares of Optimum Class A common stock, par value $0.01 per share (“Class A shares”) owned by Next Alt, and 74,153,348 shares of Optimum Class B common stock, par value $0.01 per share (“Class B shares”) owned by Next Alt, implying a price of $2.50 per common share, and Preferred Units having an aggregate initial stated value of $12,503 to such members of Optimum Communications' board of directors and executive management in exchange for 5.0 million Class A shares. Such exchanged common shares are held by Optimum CSC and were not canceled.

As required by GAAP, the Company recognized an expense of $156,555 based on the closing price of the Company's common stock on the transaction date. The expense is included in restructuring, impairments and other operating items in the accompanying consolidated statement of operations. The shares held by Optimum CSC are reflected as treasury shares on the consolidated balance sheet of Optimum Communications.

Next Alt is a personal holding company of Patrick Drahi, who is its controlling shareholder and a member of Optimum Communications’ board of directors. As of May 27, 2026, Next Alt beneficially owned approximately 39.6% of the Company’s outstanding Class A shares and approximately 99.9% of the Company’s outstanding Class B shares, representing in the aggregate approximately 94.0% of the voting power of the Company. After giving effect to the Private Exchange Transaction, Next Alt beneficially owned approximately 27.8% of the Company’s outstanding Class A shares and approximately 99.9% of the Company’s outstanding Class B shares, representing in the aggregate approximately 90.5% of the voting power of the Company.

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 $926,600 and $929,604 as of September 30, 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 sheet at December 31, 2025 were 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 September 30, 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 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 $76,500 and $82,500 as of September 30, 2026 and December 31, 2025, respectively, 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 and nine months ended September 30, 2026, we recorded a tax benefit of $680,222 and $1,488,157 on pre-tax loss of $3,538,495 and $6,781,379, respectively, resulting in an effective tax rate that was lower than the U.S. statutory rate for the three months ended September 30, 2026 and higher than the U.S. statutory rate for the nine months ended September 30, 2026. The lower rate for the three months ended September 30, 2026 is primarily due to the nonrecognition for tax purposes of the $160,800 expense related to the Tender Offer transaction, as well as an establishment of a valuation allowance against part of the deferred tax assets noted in detail below. The higher rate for the nine months ended September 30, 2026 is primarily due to the impact of state taxes, partially offset by the nonrecognition for tax purposes of the $160,800 expense related to the Tender Offer transaction and the establishment of a valuation allowance on a part of our deferred tax assets during the three months ended September

30, 2026 and the nonrecognition for tax purposes of the Private Exchange transaction recognized in the second quarter of 2026.

For the three and nine months ended September 30, 2025, we recorded a tax benefit of $433,762 and $497,373 on pre-tax loss of $1,623,352 and $1,846,220, respectively, resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher rate is primarily due to the impact of state taxes.

For the three and nine months ended September 30, 2026, we recorded a tax benefit of $680,734 and $1,489,931 on pre-tax loss of $3,540,935 and $6,789,827, respectively, resulting in an effective tax rate that was lower than the U.S. statutory rate for the three months ended September 30, 2026 and higher than the U.S. statutory rate for the nine months ended September 30, 2026. The lower rate for the three months ended September 30, 2026 is primarily due to the nonrecognition for tax purposes of the $160,800 expense related to the Tender Offer transaction as well as an establishment of a valuation allowance against part of the deferred tax assets noted in detail below. The higher rate is primarily due to the impact of state taxes, partially offset by the nonrecognition for tax purposes of the $160,800 expense related to the Tender Offer transaction and the establishment of a valuation allowance on a part of our deferred tax assets during the three months ended September 30, 2026 and nonrecognition for tax purposes of the Private Exchange transaction recognized in the second quarter of 2026.

For the three and nine months ended September 30, 2025, we recorded a tax benefit of $434,514 and $499,726 on pre-tax loss of $1,627,657 and $1,859,604, respectively, resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher rate is primarily due to the impact of state taxes.

Valuation Allowance - Optimum and CSC Holdings

Valuation allowances are established when management determines that it is more likely than not that some portion or the entire deferred tax asset will not be realized. In evaluating the need for a valuation allowance, management considers various factors, including the expected level of future taxable income, available tax planning strategies and reversals of existing taxable temporary differences.

During the three months ended September 30, 2026, we reassessed the realizability of our deferred tax assets in accordance with ASC 740, Income Taxes. Based on an evaluation of all available positive and negative evidence, including our cumulative loss position, recent operating results, impairment of the franchise rights intangible (See Note 8) and other relevant factors, management determined that it is more likely than not that a portion of our deferred tax assets will not be realized.

Accordingly, during the quarter, we established a valuation allowance of approximately $220,000 against a portion of our interest deferral deferred tax assets. Management will continue to evaluate the realizability of its deferred tax assets at each reporting date, and the amount of the valuation allowance may change in future periods as a result of changes in our operating performance, forecasts of future taxable income, and other relevant circumstances.

The awards granted in June and September 2026 vest ratably over three years in equal annual cash installments beginning in the respective grant month of 2027. The amount outstanding pursuant to these awards totaled $37,730 (net of forfeitures) as of September 30, 2026. For the nine months ended September 30, 2026, we recorded compensation cost related to these awards of $8,905.

NOTE 14. COMMITMENTS AND CONTINGENCIES

Legal Matters

On February 17, 2023, Touchstream Technologies, Inc. filed a patent infringement lawsuit, alleging infringement of certain patents directed to the use of a personal computing device, such as a mobile phone, to control playback of content on a separate display device, such as a TV. Touchstream’s allegation of infringement is based on a remote control and “Watch on TV” functionality previously available to customers through the Company’s Optimum and Optimum TV mobile applications for iPhone and Android devices. The suit was originally filed in the U.S. District Court for the Eastern District of Texas and later transferred to the U.S. District Court for the Eastern District of New York, and the parties have completed briefing on their motions for summary judgment with those motions still pending. Although the outcome of this matter cannot be predicted and the impact of the final resolution on our results of operations in a subsequent reporting period is not known, management does not believe that the resolution of the matter will have a material adverse effect on our operations or financial position or our ability to meet our financial obligations as they become due.

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. Briefing on the parties’ motions for summary judgment has been completed, and oral argument is scheduled for January 7, 2027. 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.

On June 9, 2026, Paul Berger as trustee for The Paul Berger Revocable Trust, directly on behalf of himself and all other similarly situated stockholders of Optimum Communications, Inc., filed a putative class and derivative action suit against Patrick Drahi, Dennis Mathew, Dexter Goei, Charles Stewart, Dennis Okhuijsen, Susan C. Schnabel, Raymond Svider, David Drahi, Mark Mullen, Marc Sirota, Michael Parker, Michael E. Olsen, Next Alt S.a.r.l., Next Partner, L.P. and Optimum Communications, Inc. in connection with internal reorganization and capital-raising transactions that had been recently disclosed, including the Private Exchange Transaction, and the Tender Offer (as defined below). Plaintiff brings (1) a direct claim for breach of fiduciary duty against the Director defendants and Marc Sirota, (2) a derivative claim for breach of fiduciary duty against the controller defendants (Next Alt S.a.r.l., Next Partner, L.P., and Patrick Drahi), and (3) a derivative claim for breach of fiduciary duty against the director and officer defendants (excluding two directors). Plaintiff initially moved for expedited proceedings to enjoin the Tender Offer, but withdrew that motion following the Company’s voluntary filing of supplemental disclosures. Plaintiff filed an amended complaint on September 18, 2026. 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.

On September 28, 2026, a group of holders of CSC Holdings LLC term loans filed a complaint in the Supreme Court of the State of New York, County of New York, against the Company, CSC Holdings LLC, a number of affiliated entities, and certain directors and officers. Plaintiffs assert numerous causes of action, including fraudulent transfer claims under New York law, declaratory judgment claims for alleged breaches of the CSC Credit Agreement, breach of the implied covenant of good faith and fair dealing, tortious interference with contract, aiding and abetting fraudulent transfers, civil conspiracy, breach of fiduciary duty, and aiding and abetting breaches of fiduciary duty. None of the Company and to its knowledge any of the other defendants have been served. No preliminary injunctive or other interim relief is being sought in this action. 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 this matter, on its own, 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.

(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 financial information presented below reflects 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 and nine months ended September 30, 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 impairment charges related to our indefinite-lived cable franchise rights of $2,218,489 for the nine months ended September 30, 2026 and $1,611,308 for the nine months ended September 30, 2025. Also includes attributed charges related to the non-cash exchange of Optimum shares for redeemable preferred units and the tender offer totaling $107,903 for the nine months ended September 30, 2026.

NOTE 17. SUBSEQUENT EVENTS

On November 5, 2026, following approval by the independent committees of the board of directors of Optimum Communications and the board of managers of its subsidiary Optimum CSC, holders of outstanding cash performance and deferred cash awards, including its named executive officers, were offered the opportunity to exchange those awards for cash retention awards. Optimum CSC also entered into a change in control severance agreement with a named executive officer. These arrangements are expected to result in additional compensation expense and accelerated recognition of certain previously unrecognized compensation costs in future reporting periods.
