Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”); however, in the opinion of management, the disclosures made are adequate to ensure the information presented is not misleading. The year-end consolidated balance sheet was derived from audited financial statements. ​ In the opinion of management, all normally recurring adjustments considered necessary for the fair presentation of the financial statements have been included, and the financial statements present fairly the financial position and results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results expected for the full year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with the 2022 Annual Report filed with the SEC on February 27, 2023. ​ All significant intercompany accounts and transactions have been eliminated in consolidation. ​ Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make assumptions and estimates that affect the reported amounts and disclosures of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts and disclosures of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances. To the extent there are differences between those estimates and actual results, the unaudited condensed consolidated financial statements may be materially affected. ​ ​

Franchising Operating Rights and Goodwill	Note 5. Franchising Operating Rights and Goodwill Changes in the carrying amounts of the Company’s franchise operating rights and goodwill during the three and nine months ended September 30, 2023 are set forth below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Nine months ended ​ ​ September 30, ​ September 30, ​ 2023 2022 2023 2022 ​ ​ (in millions) Franchise Operating Rights ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at beginning of period ​ $ 457.0 ​ $ 620.1 ​ $ 585.1 ​ $ 620.1 Impairment charge ​ ​ (131.7) ​ ​ — ​ ​ (259.8) ​ ​ — Balance at end of period ​ $ 325.3 ​ $ 620.1 ​ $ 325.3 ​ $ 620.1 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Goodwill ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at beginning of period ​ $ 225.1 ​ $ 225.1 ​ $ 225.1 ​ $ 225.1 Impairment charge ​ — ​ — ​ — ​ — Balance at end of period ​ $ 225.1 ​ $ 225.1 ​ $ 225.1 ​ $ 225.1 ​ Due to the decline in the Company’s projected cash flows, combined with a reduction in stock price, which represented a triggering event during the three months ended September 30, 2023, the Company performed an interim impairment analysis of its franchise operating rights and goodwill. ​ Franchise Operating Rights Franchise operating rights are evaluated for impairment by comparing the carrying value of the intangible asset to its estimated fair value, utilizing both quantitative and qualitative methods, at the lowest level of identifiable cash flows, which generally represent the markets in which the Company operates. Qualitative analysis is performed for franchise assets in the event the previous analysis indicates that there is a significant margin between the estimated fair value of franchise operating rights and the carrying value of those rights, and that it is more likely than not that the estimated fair value equals or exceeds its carrying value. For the interim impairment analysis, all franchise operating rights were evaluated using quantitative analysis. The Company calculates the estimated fair value of franchise operating rights using the multi-period excess earnings method, an income approach, which calculates the estimated fair value of an intangible asset by discounting its future cash flows. The estimated fair value is determined based on discrete discounted future cash flows attributable to each franchise operating right intangible asset using assumptions consistent with internal forecasts. Assumptions key in estimating fair value under this method include, but are not limited to, revenue and subscriber growth rates (less anticipated customer churn), operating expenditures, capital expenditures (including any build out), market share achieved or market multiples, contributory asset charge rates, tax rates and a discount rate. The discount rate used in the model represents a weighted average cost of capital and the perceived risk associated with an intangible asset such as the Company’s franchise operating rights. If the fair value of the franchise operating right asset was less than its carrying value, the Company recognizes an impairment charge for the difference between the fair value and the carrying value of the asset. As a result of the interim impairment analyses performed, the estimated fair value of certain franchise operating right assets was determined to be below the carrying value, which resulted in the recognition of non-cash impairment losses for the three months ended September 30, 2023. ​ The Company also performed an interim impairment analysis for the three months ended June 30, 2023, which resulted in the recognition of non-cash impairment losses. ​ The table below outlines the impairment charges recognized in each market for the periods presented: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2023 ​ ​ Three month ended ​ Nine months ended ​ ​ (in millions) Columbus, GA ​ $ 35.4 ​ $ 39.1 Huntsville, AL ​ ​ 21.5 ​ ​ 81.5 Augusta, GA ​ ​ 20.5 ​ ​ 44.9 Montgomery, AL ​ ​ 20.0 ​ ​ 33.0 Charleston, SC ​ ​ 12.5 ​ ​ 12.5 Panama City, FL ​ ​ 9.5 ​ ​ 23.0 Valley, AL ​ ​ 6.5 ​ ​ 10.5 Knoxville, TN ​ ​ 5.8 ​ ​ 5.8 Newnan, GA ​ ​ - ​ ​ 9.5 Total ​ $ 131.7 ​ $ 259.8 ​ The primary driver of the impairment charge was a decline in the estimated fair market value of indefinite-lived intangible assets in certain markets. The decline is primarily due to declining cash flows in the markets listed above, which results in an increase in the discount rate used to estimate fair value, with the decline in the Company’s common stock price further contributing to the impairment change. The impairment charges do not have an impact on the Company’s intent and/or ability to renew or extend existing franchise operating rights. Goodwill For the interim impairment analysis, the Company quantitatively evaluated goodwill at the consolidated reporting unit level. The Company determined the estimated fair value utilizing a market approach that incorporated the approximate market capitalization as of the interim testing date, increased by the quoted market price of the Company’s debt and adjusted for a control premium. Based on the interim analysis, the estimated fair value of goodwill exceeded the carrying value, as such, no impairment charge related to goodwill was recognized during the three and nine months ended September 30, 2023.

Refinancing of the Term B Loans and Revolving Credit Facility ​ On December 20, 2021, the Company entered into a new secured credit agreement with Morgan Stanley Senior Funding, Inc., as administrative agent, collateral agent and issuing bank (the “Credit Agreement”). The Credit Agreement consists of (i) a new Term B Loan in an aggregate principal amount of $730.0 million and (ii) a $250.0 million revolving credit commitment. The Term B Loan matures in December 2028 and bears interest at a rate equal to the Secured Overnight Financing Rate (“SOFR”) plus 3.00%, subject to a 50 basis point floor, and the revolving credit commitment bears interest at a rate equal to SOFR plus 2.75%, subject to a 50 basis point commitment fee rate for unused commitments, and matures in December 2026. The Senior Secured Term B loans and Revolving Credit Facility are secured on a first-priority basis by a lien on substantially all of the Company’s assets, subject to certain exceptions and permitted liens. ​ As of September 30, 2023, the Company was in compliance with all debt covenants.

Stock-Based Compensation
Stock-Based Compensation	Note 8. Stock-Based Compensation The Company’s stock incentive plan, the 2017 Omnibus Incentive Plan, provides for grants of stock options, restricted stock and performance awards. The Company’s directors, officers and other employees and persons who engage in services for the Company are eligible for grants under the plan. The stock incentive plan has authorized 15,924,128 shares of the Company’s common stock to be available for issuance, subject to adjustment in the event of a reorganization, stock split, merger or similar change in the Company’s corporate structure or the outstanding shares of common stock. ​ Restricted stock awards generally vest ratably over a four year period based on the date of grant. For restricted stock awards that contain only service conditions for vesting, the Company calculates the award fair value based on the closing stock price on the accounting grant date. ​ The Company recorded $3.5 million and $6.4 million of total non-cash compensation expense for the three months ended September 30, 2023 and 2022, respectively, and recorded $13.9 million and $18.5 million for the nine months ended September 30, 2023 and 2022, respectively. Certain awards were modified during the year ended December 31, 2021 and were classified as liabilities. During the nine months ended September 30, 2023, the remainder of these liability-based awards were settled with shares of restricted stock for approximately $0.3 million. The non-cash compensation expense associated with these awards was nil and $0.5 million for the nine months ended September 30, 2023 and 2022, respectively and is included in total non-cash compensation expense. The following table presents restricted stock activity during the nine months ended September 30, 2023: ​ ​ ​ ​ ​ Number of ​ ​ Unvested ​ ​ Restricted Stock ​ ​ Shares Outstanding, beginning of period ​ 3,223,995 Granted ​ 2,075,854 Vested ​ (2,283,097) Forfeited ​ (317,453) Outstanding, end of period(1) ​ 2,699,299 (1) The total outstanding non-vested shares of restricted stock awards granted to employees and directors are included in total outstanding shares as of September 30, 2023. Grants of Performance Shares On March 3, 2023, the Company granted 264,028 performance shares which will vest based on the Company’s achievement level relative to the following performance measures at December 31, 2025: 50% based upon the Company’s Total Shareholder Return (“TSR”) relative to the TSRs of the Company’s peer group and 50% based on the Company’s three-year cumulative EBITDA metric. EBITDA is defined as net income (loss) before net interest expense, income taxes, depreciation and amortization (including impairments), impairment losses on intangibles and goodwill, the write-off of any asset, loss on early extinguishment of debt, integration and restructuring expenses and all non-cash charges and expenses (including stock compensation expense) and certain other income and expenses. Upon achievement of the minimum threshold performance metric, the grantee may earn 50% to 200% of their respective target shares based on the performance goal. The performance shares based on relative TSR performance have a market condition and are valued using a Monte Carlo simulation model on the grant date, which resulted in a grant date fair value of $16.19 per share. The estimated fair value is amortized to expense over the requisite service period, which ends on December 31, 2025. The following assumptions were used in the Monte Carlo simulation for computing the grant date fair value of the performance shares with a market condition: risk-free interest rate of 4.62%, volatility factors in the expected market price of the Company's common shares of 51.61% and an expected life of three years. The performance shares based on three-year cumulative EBITDA have a performance condition. The probability of achieving the performance condition is assessed at each reporting period. If it is deemed probable that the performance condition will be met, compensation cost will be recognized based on the closing price per share of the Company's common stock on the date of the grant multiplied by the number of awards expected to be earned. If it is deemed that it is not probable that the performance condition will be met, the Company will discontinue the recognition of compensation cost and any compensation cost previously recorded will be reversed. At September 30, 2023, the Company determined that it was not probable that the performance condition based on three-year cumulative EBITDA would be met for the performance shares issued in 2022 and 2023. Achievement of the performance conditions associated with the 2021 performance shares was deemed probable.

Earnings per Common Share	Note 10. Earnings per Common Share Basic earnings or loss per share attributable to the Company’s common stockholders is computed by dividing net income or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings or loss per share attributable to common stockholders presents the dilutive effect, if any, on a per share basis of potential common shares (such as restricted stock units) as if they had been vested or converted during the periods presented. No such items were included in the computation of diluted loss or earnings per share for the three and nine months ended September 30, 2023 because the Company incurred a net loss and the effect of inclusion would have been anti-dilutive. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Nine months ended ​ ​ September 30, ​ September 30, ​ 2023 2022 2023 2022 ​ ​ (in millions, except share data) Net (loss) income ​ $ (104.5) ​ $ 0.5 ​ $ (244.2) ​ $ 10.2 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic weighted-average shares ​ 80,888,537 ​ 84,274,050 ​ 81,797,740 ​ 83,908,691 Effect of dilutive securities: ​ ​ ​ ​ ​ ​ ​ ​ Restricted stock awards ​ — ​ 2,461,196 ​ — ​ 2,763,184 Diluted weighted-average shares ​ 80,888,537 ​ 86,735,246 ​ 81,797,740 ​ 86,671,875 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted (loss) earnings per common share ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic ​ $ (1.29) ​ $ 0.01 ​ $ (2.99) ​ $ 0.12 Diluted ​ $ (1.29) ​ $ 0.01 ​ $ (2.99) ​ $ 0.12 ​ The dilutive effect of the potential common shares from the performance shares is included in diluted earnings per share upon the satisfaction of certain performance and market conditions. These conditions are evaluated at each reporting period and if the conditions have been satisfied during the reporting period, the number of contingently issuable shares are included in the computation of diluted earnings per share. As of September 30, 2023, the Company determined the performance conditions were not yet achieved; however, the market conditions indicated a certain level of achievement within the payout range. Therefore, the contingently issuable performance shares associated with the market condition are included in the computation of diluted earnings per share, if they have a dilutive effect on earnings per share.

Fair Value Measurements
Fair Value Measurements	Note 11. Fair Value Measurements The fair values of cash and cash equivalents, receivables and trade payables approximate their carrying values due to the short-term nature of these instruments. For assets and liabilities of a long-term nature, the Company determines fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Market or observable inputs are the preferred source of values, followed by unobservable inputs or assumptions based on hypothetical transactions in the absence of market inputs. The Company applies the following hierarchy in determining fair value: ● Level 1, defined as observable inputs being quoted prices in active markets for identical assets; ● Level 2, defined as observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and ● Level 3, defined as values determined using models that utilize significant unobservable inputs for which little or no market data exists, discounted cash flow methodologies or similar techniques, or other determinations requiring significant management judgment or estimation. The estimated fair value of the Company’s long-term debt is based on dealer quotes considering current market rates for the Company’s credit facility and is classified as Level 2. The ratio of the Company’s aggregate debt balance has trended from quoted market prices in active markets to quoted prices in non-active markets. The fair value of the Company’s long-term debt was valued at $702.9 million and $699.2 million as of September 30, 2023 and December 31, 2022, respectively. Long-term debt fair value does not include debt issuance costs and discounts. There were no transfers into or out of Level 1, 2 or 3 during the periods ended September 30, 2023 and December 31, 2022. The Company’s nonfinancial assets such as franchise operating rights, property, plant, and equipment, and other intangible assets are not measured at fair value on a recurring basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence that an impairment may exist. When such impairments are recorded, fair values are generally classified within Level 3 of the valuation hierarchy.

Income Taxes	Note 12. Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the difference is expected to reverse. Additionally, the impact on deferred tax assets and liabilities of changes in tax rates is reflected in the financial statements in the period that includes the date of enactment. The Company reported income tax benefit of $35.6 million and income tax expense of $0.4 million for the three months ended September 30, 2023 and 2022, respectively, and income tax benefit of $84.4 million and income tax expense of $4.5 million for the nine months ended September 30, 2023 and 2022, respectively.

Commitments and Contingencies	Note 13. Commitments and Contingencies On March 7, 2018, Sprint Communications Company LP (“Sprint”) filed a complaint in the U.S. District Court for the District of Delaware alleging that the Company infringed a set of patents directed to the provision of Voice over Internet Protocol services. This lawsuit was part of a larger, decade long patent enforcement campaign by Sprint aimed at numerous service providers in the broadband and telecommunications industry. In April 2023, prior to the commencement of the Company’s jury trial on April 24, 2023, the Company and Sprint entered into settlement discussions and also conducted a formal mediation. Those discussions culminated in a negotiated resolution of the pending litigation, for which the parties executed a binding term sheet on April 19, 2023, and a Confidential Settlement and License Agreement on April 28, 2023. The terms of the settlement are confidential, but the agreement does obligate the Company to make payments to Sprint over the course of three years in exchange for a full release of all liability. The Company intends to pursue funding contributions for that settlement from third parties implicated by Sprint’s claims and the Company’s defense, including indemnification claims against the Company’s various affected equipment providers. As a result of the settlement, the Company accrued $46.8 million as of March 31, 2023, and the associated expense is included in selling, general and administrative expenses. The Company does not believe that the settlement will have a material impact on the Company’s capital expenditures. The Company is also party to various legal proceedings (including individual, class and putative class actions) arising in the normal course of its business covering a wide range of matters and types of claims including, but not limited to, general contracts, billing disputes, rights of access, programming, taxes, fees and surcharges, consumer protection, trademark and patent infringement, employment, regulatory, tort, claims of competitors and disputes with other carriers. In accordance with GAAP, the Company accrues an expense for pending litigation when it determines that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. Legal defense costs are expensed as incurred. None of the Company’s existing accruals for pending matters are material. The Company consistently monitors its pending litigation for the purpose of adjusting its accruals and revising its disclosures accordingly, in accordance with GAAP, when required. However, litigation is subject to uncertainty, and the outcome of any particular matter is not predictable. The Company will vigorously defend its interests in pending litigation, and the Company believes that the ultimate resolution of all such matters, after considering insurance coverage or other indemnities to which it is entitled, will not have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”); however, in the opinion of management, the disclosures made are adequate to ensure the information presented is not misleading. The year-end consolidated balance sheet was derived from audited financial statements. ​ In the opinion of management, all normally recurring adjustments considered necessary for the fair presentation of the financial statements have been included, and the financial statements present fairly the financial position and results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results expected for the full year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with the 2022 Annual Report filed with the SEC on February 27, 2023. ​ All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make assumptions and estimates that affect the reported amounts and disclosures of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts and disclosures of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances. To the extent there are differences between those estimates and actual results, the unaudited condensed consolidated financial statements may be materially affected.
