The December 31, 2024 year-end balance sheet data presented herein was derived from the Company’s audited consolidated financial statements included in the 2024 Form 10-K, but does not include all disclosures required by GAAP. The Company’s interim results of operations may not be indicative of its future results.

Principles of Consolidation. The accompanying condensed consolidated financial statements include the accounts of the Company, including its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Segment Reporting. Accounting Standards Codification 280 -Segment Reporting requires the disclosure of factors used to identify an entity’s reportable segments. Based on the Company’s chief operating decision maker’s (“CODM”) review and assessment of the Company’s operating performance for purposes of performance monitoring and resource allocation, the Company determined that its operations, including the decisions to allocate resources and deploy capital, are organized and managed on a consolidated basis. Accordingly, management has identifiedone operating segment, which is its reportable segment, under this organizational and reporting structure.

Use of Estimates. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported herein. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates and underlying assumptions.

Recently Adopted Accounting Pronouncements. In December 2023, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures.

3. SEGMENT REPORTING

Based on the way the Company’s CODM, who is the Company’s CEO, reviews and assesses the Company’s operations for purposes of performance monitoring and resource allocation, the Company determined that its operations and the decisions to allocate resources and deploy capital are organized and managed on a consolidated basis. Accordingly, management has identifiedone operating segment, which is its reportable segment, under this organizational and reporting structure.

The Company's consolidated net income (loss) is the GAAP measure of profit or loss which is used by the CODM to allocate resources and assess performance on a monthly basis. Such measure is compared against prior periods to identify, assess and respond to trends.

The following table includes the significant expense categories and amounts that are regularly provided to the CODM (in thousands):

(1)Includes other operating costs (such as marketing, software and maintenance expenses), depreciation and amortization, net gain (loss) on asset sales and disposals, asset impairments, net interest expense, net other income (expense), income tax (provision) benefit, net equity method investment income (loss) and certain other non-cash, non-core and/or non-recurring costs. Refer to note 7 for further information regarding the asset impairments. Amounts for the three months ended September 30, 2025 and 2024 include interest expense of $36.3 million and $39.1 million, respectively, and interest and investment income of $4.3 million and $4.9 million, respectively.

5. EQUITY INVESTMENTS

In August 2025, the Company divested its equity investment in Northwest Fiber Holdco., LLC, a fiber internet service provider ("Ziply") for $109.9 million in proceeds and recognized a $59.9 million gain. In July 2025, the Company divested its equity investments in MetroNet Systems, LLC, a fiber internet service provider ("MetroNet") for $14.1 million in cash proceeds and recognized a $7.1 million gain. In March 2025, the Company divested an equity investment for $11.1 million in cash proceeds and recognized a $3.6 million gain.

In June 2024, the Company invested an additional $20.0 million in AMG Technology Holdings, LLC, a wireless internet service provider ("Nextlink"), increasing its equity interest to approximately 22%. Prior to this additional investment, Nextlink was accounted for as a cost method investment. After the investment, Nextlink is accounted for as an equity method investment with a one quarter reporting lag.

Prior to June 30, 2024, the Company held a call option to purchase all but not less than all of the remaining equity interests in MBI, in which the Company owns an approximately 45% equity interest, that the Company does not already own between January 1, 2023 and June 30, 2024. The call option expired unexercised on June 30, 2024. Further, certain investors in MBI held a put option to sell (and to cause all members of MBI other than the Company to sell) to the Company all but not less than all of the remaining equity interests in MBI that the Company does not already own between July 1, 2025 and September 30, 2025 (these call and put options are collectively referred to as the "Old MBI Net Option").

In December 2024, the Company amended its agreement with MBI, to, among other things, (i) reinstate the Company's expired call option to acquire the remaining equity interests in MBI, exercisable any time after the availability of MBI's June 30, 2025 financial statements (unless the Put Option (as defined below) has already been exercised) (the "Call Option"); (ii) amend the put option held by certain other investors in MBI to sell (and to cause all members of MBI other than the Company to sell) to the Company all membership interests not held by the Company such that the exercise can occur no earlier than January 1, 2026 (unless a change of control of the Company occurs prior to that date), and the closing can occur no earlier than October 1, 2026 (unless the Company elects to cause the closing to occur earlier) (the "Put Option," and together with the Call Option, the "New MBI Net Option"); (iii) require the Company to make a $250 million net upfront cash payment to the other members of MBI (the "Upfront Payment"), which was paid on December 20, 2024; and (iv) provide for the other members of MBI to immediately receive, indirectly, the proceeds from $100 million of new indebtedness recently incurred by a subsidiary of MBI (the "New MBI Debt") (collectively, the "MBI Amendment"). The purchase price payable by the Company upon the exercise of the Call Option or Put Option, as applicable, is to be calculated under a formula based on a multiple of MBI’s adjusted earnings before interest, taxes, depreciation and amortization ("MBI's adjusted EBITDA") for the twelve-month period ended June 30, 2025, and MBI’s total net indebtedness. The aggregate amount of the Upfront Payment and the New MBI Debt will reduce the Call Price or Put Price payable upon the exercise of the Call Option or Put Option, as applicable, and the impact of the New MBI Debt (and the associated interest and fees) will be excluded from the calculation of MBI's total net indebtedness for purposes of determining such purchase price. Further, if the closing of the Put Option or Call Option occurs prior to October 1, 2026, the Call Price or Put Price payable will be discounted, from October 1, 2026 to the closing, at a per annum rate of 12%.

The New MBI Net Option is measured at fair value on a quarterly basis using Monte Carlo simulations that rely on assumptions around MBI’s equity value and volatility (refer to note 10 for further information).

The carrying value of the Company's equity investments consisted of the following (dollars in thousands):

(1)Point Broadband Holdings, LLC, a fiber internet service provider ("Point").

(2)Visionary Communications, Inc., an internet service provider ("Visionary").

(3)The Company does not have a controlling financial interest and does not consolidate Clearwave Fiber for financial reporting purposes but accounts for its interest under the equity method of accounting as the entity’s governance arrangements require certain of the designees of the other unit holders to consent to all significant decisions.

(4)Represents the Company's percentage ownership of the total outstanding equity units in Clearwave Fiber. The Company's ownership interest in Clearwave Fiber is in the form of common equity units and the ownership interest in Clearwave Fiber of the unaffiliated third-party investors is in the form of convertible preferred equity units. The convertible preferred equity units held by the unaffiliated third-party investors are subject to a specified preferred return in relation to the common equity units held by the Company. As a result of the economic and other attributes of the various classes of equity units in Clearwave Fiber, the Company's percentage ownership of the total outstanding equity units in Clearwave Fiber may differ from its economic interest in Clearwave Fiber.

The carrying value of MBI exceeded the Company’s underlying equity in MBI’s net assets by $359.9 million and $365.7 million as of September 30, 2025 and December 31, 2024, respectively.

Equity method investment income (loss), which increase (decrease) the carrying value of the respective investment, and which are recorded on a one quarter lag, along with other equity investment activity reflected in the condensed consolidated statements of operations and comprehensive income (loss), were as follows (in thousands):

(1)The amount for the nine months ended September 30, 2025 includes $28.0 million related to non-cash impairment charges recorded by Clearwave Fiber.

(2)The Company identified a $186.6 million difference between the fair values of certain of MBI’s finite-lived intangible assets and the respective carrying values recorded by MBI, of which $84.0 million was attributable to the Company’s ~45% pro rata portion. The Company is amortizing its share on an accelerated basis over the lives of the respective assets. For the three months ended September 30, 2025, the Company recognized $1.5 million of its proportionate share of MBI’s net income and $1.7 million of its proportionate share of basis difference amortization. For the three months ended September 30, 2024, the Company recognized $0.9 million of its proportionate share of MBI's net income and $2.1 million of its proportionate share of basis difference amortization. For the nine months ended September 30, 2025, the Company recognized $1.9 million of its proportionate share of MBI’s net income and $5.4 million of its proportionate share of basis difference amortization. For the nine months ended September 30, 2024, the Company recognized $3.9 million of its proportionate share of MBI's net income and $6.6 million of its proportionate share of basis difference amortization.

The carrying value of the Company’s equity investments without readily determinable fair values are determined based on the fair value as of their respective acquisition dates and adjusted if and when relevant market transactions indicate fair value has changed. No fair value adjustments were recorded to the carrying values of any equity investments in 2025. In prior periods, the Company recorded cumulative upward adjustments to the carrying values of its Point and Nextlink investments of $12.3 million and $6.9 million, respectively. The Company assesses each equity investment for indicators of impairment on a quarterly basis. No impairments were recorded for any of the periods presented.

6. PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment consisted of the following (in thousands):

Depreciation and amortization expense for property, plant and equipment was $68.3 million and $68.6 million for the three months ended September 30, 2025 and 2024, respectively, and $208.7 million and $206.5 million for the nine months ended September 30, 2025 and 2024, respectively.

7. GOODWILL AND INTANGIBLE ASSETS

During the second quarter of 2025, the Company determined that a triggering event had occurred that required interim impairment assessments of its indefinite-lived intangible assets and goodwill as a result of the decline in the price of the Company's common stock subsequent to its first quarter 2025 earnings release through June 30, 2025.

Based on qualitative assessments of its finite-lived intangible assets, no impairments of such assets were identified. Using the multi-period excess earnings method of the income approach, whose significant inputs and assumptions include forecasted revenues, subscriber attrition rates, margins, capital expenditures, contributory asset charges, income tax rates, long-term growth rates and a discount rate, to determine fair value, the Company's franchise agreements asset was determined to be impaired by $497.2 million. Using i) the discounted cash flow method of the income approach, whose significant inputs and assumptions include forecasted revenues, margins, capital expenditures, working capital levels, income tax rates, long-term growth rates and a discount rate, and ii) the guideline public company method of the market approach, whose significant inputs and assumptions include the identification of appropriate market participants; consensus earnings before interest, taxes, depreciation and amortization estimates; and the selection of enterprise value multiples, the Company's goodwill was determined to be impaired by $88.8 million. These non-cash charges are included within asset impairments in the condensed consolidated statement of operations and comprehensive income (loss) for the nine months ended September 30, 2025.

The change in the Company's goodwill balance was as follows (dollars in thousands):

Intangible assets consisted of the following (dollars in thousands):

The Revolving Credit Facility also gives the Company the ability to issue letters of credit, which reduce the amount available for borrowing under the Revolving Credit Facility. No letters of credit were issued under the Revolving Credit Facility as of September 30, 2025.

Under the Credit Agreement, the interest margins applicable to the Senior Credit Facilities are, at the Company’s option, equal to either the Secured Overnight Financing Rate ("SOFR") or a base rate, plus an applicable margin equal to, (i) with respect to the Revolving Credit Facility,1.25% to 1.75% plus a 10 basis point credit spread adjustment for SOFR loans and 0.25% to 0.75% for base rate loans, determined on a quarterly basis by reference to a pricing grid based on the Company’s Total Net Leverage Ratio (as defined in the Credit Agreement), (ii) with respect to the Term Loan B-2 and the Term Loan B-3,2.25% plus a 10 basis point credit spread adjustment for SOFR loans and 1.25% for base rate loans and (iii) with respect to the Term Loan B-4,2.0% plus an approximately 11.4 to 42.8 basis point credit spread adjustment based on the interest period elected for SOFR loans and 1.0% for base rate loans.

9. INTEREST RATE SWAPS

The Company is party totwo interest rate swap agreements, designated as cash flow hedges, to manage the risk of fluctuations in interest rates on its variable rate SOFR debt. Changes in the fair values of the interest rate swaps are reported through other comprehensive income until the underlying hedged debt’s interest expense impacts net income (loss), at which point the corresponding change in fair value is reclassified from accumulated other comprehensive income to net interest expense. Proceeds or payments from the interest rate swaps are included within cash flows from operating activities in the condensed consolidated statements of cash flows.

A summary of the significant terms of the Company’s interest rate swap agreements is as follows (dollars in thousands):

(1)Each swap may be terminated prior to the scheduled maturity at the election of the Company or the financial institution counterparty under the terms provided in each swap agreement.

The combined fair values of the Company’s interest rate swaps are reflected within the condensed consolidated balance sheets as follows (in thousands):

The combined effect of the Company’s interest rate swaps on the condensed consolidated statements of operations and comprehensive income (loss) was as follows (in thousands):

The Company does not hold any derivative instruments for speculative trading purposes.

10. FAIR VALUE MEASUREMENTS

Financial Assets and Liabilities. The Company has estimated the fair values of its financial instruments as of September 30, 2025 using available market information or other appropriate valuation methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, the following fair value estimates are not necessarily indicative of the amounts the Company would realize in an actual market exchange.

The fair value hierarchy levels, carrying amounts and related fair value of the Company’s financial assets and liabilities as of September 30, 2025 were as follows (in thousands):

Money market investments are held primarily in U.S. Treasury securities and registered money market funds and are valued using a market approach based on quoted market prices (level 1). Money market investments with original maturities of three months or less are included within cash and cash equivalents in the condensed consolidated balance sheets. Interest rate swaps are measured at fair value within the condensed consolidated balance sheets on a recurring basis, with fair value determined using standard valuation models with assumptions about interest rates being based on those observed in underlying markets (level 2). The fair value of the New MBI Net Option is measured using Monte Carlo simulations that use inputs considered unobservable and significant to the fair value measurement (level 3). The fair value of the term loans, Revolving Credit Facility, Senior Notes and Convertible Notes are estimated based on market prices for similar instruments in active markets (level 2).

The assumptions used to determine the fair value of the New MBI Net Option consisted of the following:

(1)The purchase price payable by the Company upon the exercise of the Call Option or Put Option, as applicable, is calculated under a formula based on a multiple of MBI's adjusted EBITDA for the twelve-month period ended June 30, 2025, and MBI’s total net indebtedness. As this twelve-month measurement period ended on June 30, 2025, assumptions regarding MBI's adjusted EBITDA volatility and MBI's risk-adjusted discount rate assumptions are no longer applicable when calculating the fair value of the New MBI Net Option as of September 30, 2025.

The Company regularly evaluates each of the assumptions used in establishing the fair value of the New MBI Net Option. Significant changes in any of these assumptions could result in a significantly lower or higher fair value measurement. A change in one of these assumptions is not necessarily accompanied by a change in another assumption. Refer to note 5 for further information on the New MBI Net Option.

The carrying amounts of accounts receivable, prepaid and other current assets, accounts payable and accrued liabilities and other financial assets and liabilities approximate fair value because of the short-term nature of these instruments.

Nonfinancial Assets and Liabilities. The Company’s nonfinancial assets, such as property, plant and equipment, intangible assets and goodwill, are not measured at fair value on a recurring basis. Assets acquired, including identifiable intangible assets and goodwill, and liabilities assumed in acquisitions are recorded at fair value on the respective acquisition dates, subject to potential future measurement period adjustments. Nonfinancial assets are subject to fair value adjustments when there is evidence that impairment may exist. Other than the impairment of the Company's franchise agreements and goodwill recognized in the second quarter of 2025 (refer to note 7), no other impairments were recorded during the nine months ended September 30, 2025 or 2024.

11. STOCKHOLDERS’ EQUITY

Treasury Stock. Treasury stock is recorded at cost and is presented as a reduction of stockholders’ equity in the condensed consolidated financial statements. Treasury shares of 540,356 held at September 30, 2025 include shares repurchased under the Company’s share repurchase programs and shares withheld for withholding tax, as described below.

Share Repurchase Program. On May 20, 2022, the Company's board of directors (the "Board") authorized up to $450.0 million of share repurchases (with no cap as to the number of shares of common stock) (the "Share Repurchase Program"). The Company had $143.1 million of remaining share repurchase authorization under the Share Repurchase Program as of September 30, 2025. Additional purchases under the Share Repurchase Program may be made from time to time on the open market and in privately negotiated transactions, and we may opportunistically and prudently consider buying back shares under our remaining share repurchase authorization. The size and timing of any additional purchases are based on a number of factors, including share price, trading levels and business and market conditions. Since the Company first became publicly traded in 2015 through September 30, 2025, the Company has repurchased 646,244 shares of its common stock at an aggregate cost of $556.9 million. The Company didnot repurchase any of its common stock during the nine months ended September 30, 2025 or 2024.

Tax Withholding for Equity Awards. At the employee’s option, shares of common stock are withheld by the Company upon the vesting of restricted stock awards, restricted stock units ("RSUs"), dividend equivalent units (together with restricted stock awards and RSUs, "Restricted Stock") and the exercise of stock appreciation rights (“SARs”) to cover the applicable statutory minimum amount of employee withholding taxes, which the Company then pays to the taxing authorities in cash. The amounts remitted during each of the three months ended September 30, 2025 and 2024 was $0.3 million and less than $0.1 million, for which the Company withheld 6 and 106 shares of common stock, respectively. The amounts remitted during the nine months ended September 30, 2025 and 2024 were $2.6 million and $2.8 million, for which the Company withheld 1,529 and 2,510 shares of common stock, respectively.

12. EQUITY-BASED COMPENSATION

The Company's stockholders approved the Cable One, Inc. 2022 Omnibus Incentive Compensation Plan (the “2022 Plan”) at the annual meeting of stockholders held on May 20, 2022. The 2022 Plan provides for grants of incentive stock options, non-qualified stock options, Restricted Stock, SARs, cash-based awards, performance-based awards and other stock-based awards, including deferred stock units, and superseded and replaced the Amended and Restated Cable One, Inc. 2015 Omnibus Incentive Compensation Plan. Directors, officers, employees and consultants of the Company are eligible for grants under the 2022 Plan as part of the Company’s long-term incentive compensation programs. At September 30, 2025,238,065 shares were available for issuance under the 2022 Plan.

Beginning in 2025, new RSU grants contain retirement eligibility provisions that result in accelerated expensing of awards granted to associates that satisfy certain age and service conditions.

Compensation expense associated with equity-based awards is recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the award (unless any retirement eligibility provisions are satisfied earlier), with forfeitures recognized as incurred. The Company’s equity-based compensation expense, included within selling, general and administrative expenses in the condensed consolidated statements of operations and comprehensive income (loss), was as follows (in thousands):

The Company recognized excess tax shortfalls of $0.6 million and $0.4 million for the three months ended September 30, 2025 and 2024, respectively, and excess tax shortfalls of $2.6 million and $2.1 million during the nine months ended September 30, 2025 and 2024, respectively. The deferred tax asset related to all outstanding equity-based awards was $8.3 million and $8.6 million as of September 30, 2025 and December 31, 2024, respectively.

Restricted Stock. A summary of Restricted Stock activity during the nine months ended September 30, 2025 is as follows:

At September 30, 2025, there was $33.1 million of unrecognized compensation expense related to Restricted Stock, which is expected to be recognized over a weighted average period of 1.3 years.

The significant inputs and resulting weighted average grant date fair value for market-based award grants were as follows:

Stock Appreciation Rights. A summary of SARs activity during the nine months ended September 30, 2025 is as follows:

At September 30, 2025, there wasno significant unrecognized compensation expense related to SARs.

13. INCOME TAXES

The Company’s effective tax rate was 19.2% and 19.5% for the three months ended September 30, 2025 and 2024, respectively, and (26.9)% and 20.4% for the nine months ended September 30, 2025 and 2024, respectively. The effective tax rate for the three months ended September 30, 2025 remained consistent with the prior year quarter. The decrease in effective tax rate for the nine months ended September 30, 2025 compared to the prior year period was due primarily to a decrease in income tax expense of $129.6 million resulting from asset impairments recognized in the second quarter of 2025.

14. OTHER INCOME AND EXPENSE

Other income (expense), net, consisted of the following (in thousands):

(1)Represents a gain related to C-band spectrum relocation funding received from the federal government.

15. NET INCOME (LOSS) PER COMMON SHARE

Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. The denominator used in calculating diluted net income (loss) per common share further includes any common shares available to be issued upon vesting or exercise of outstanding equity-based compensation awards if such inclusion would be dilutive, calculated using the treasury stock method, and any common shares to be issued upon conversion of the Convertible Notes, calculated using the if-converted method.

The computation of basic and diluted net income (loss) per common share was as follows (dollars in thousands, except per share amounts):

(1)Because the Company incurred a net loss for the nine months ended September 30, 2025 (primarily due to asset impairments recognized during the second quarter of 2025), diluted net loss per share is equal to basic net loss per share for the period. Therefore, no adjustments are shown to the numerator or denominator within the table.

(2)Equity-based compensation awards whose impact is considered to be anti-dilutive under the treasury stock method were excluded from the diluted net income (loss) per common share calculation.

(3)Based on a conversion rate of 0.4394 shares of common stock per weighted $1,000 principal amount of Convertible Notes outstanding for all periods presented.

During the first quarter of 2025, the Company identified an immaterial error in its diluted earnings per share calculation for the year ended December 31, 2024. The if-converted method for the Convertible Notes was incorrectly applied during the period, as its effect was anti-dilutive. Diluted earnings per share for the year ended December 31, 2024 should have been $2.57 instead of the $3.43 reported. The Company plans to revise the disclosure in its Annual Report on Form 10-K for the year ending December 31, 2025. No other periods were impacted.

16. COMMITMENTS AND CONTINGENCIES

Contractual Obligations. The Company has obligations to make future payments for goods and services under certain contractual arrangements. These contractual obligations secure the future rights to various goods and services to be used in the normal course of the Company’s operations. In accordance with applicable accounting rules, the future rights and obligations pertaining to firm commitments, such as certain purchase obligations under contracts, are not reflected as assets or liabilities in the condensed consolidated balance sheets.

As of September 30, 2025, with the exception of debt payments (refer to note 8 for the updated future maturities of outstanding borrowings table), there have been no material changes to the contractual obligations previously disclosed in the 2024 Form 10-K.

In addition, the Company incurs recurring utility pole rental costs and fees imposed by various governmental authorities, including franchise fees, as part of its operations. However, these costs are not included in the Company’s contractual obligations as they are cancellable on short notice, in the case of pole rental costs, or are passed through on a monthly basis to the Company’s customers and are periodically remitted to authorities, in the case of fees imposed by governmental authorities. The Company also has franchise agreements requiring plant construction and the provision of services to customers within the franchise areas. In connection with these obligations under existing franchise agreements, the Company obtains surety bonds or letters of credit guaranteeing performance to municipalities and public utilities and payment of insurance premiums. Payments under these arrangements are required only in the remote event of nonperformance.

Litigation and Legal Matters. The Company is subject to complaints and administrative proceedings and has been a defendant in various civil lawsuits that have arisen in the ordinary course of its business. Such matters include contract disputes; actions alleging negligence, invasion of privacy, trademark, copyright and patent infringement, and violations of applicable wage and hour laws; statutory or common law claims involving current and former employees; and other matters. Although the outcomes of any legal claims and proceedings against the Company cannot be predicted with certainty, based on currently available information, the Company believes that there are no existing claims or proceedings that are likely to have a material adverse effect on its business, financial condition, results of operations or cash flows.

Regulation in the Company’s Industry. The Company’s operations are extensively regulated by the Federal Communications Commission (the "FCC"), some state governments and most local governments. The FCC has the authority to enforce its regulations through the imposition of substantial fines, the issuance of cease-and-desist orders and/or the imposition of other administrative sanctions, such as the revocation of FCC licenses needed to operate certain transmission facilities used in connection with cable operations. Future legislative and regulatory changes could adversely affect the Company’s operations.
