BASIS OF PRESENTATION	NOTE 1—BASIS OF PRESENTATION ​ AMC Entertainment Holdings, Inc. (“Holdings”), through its direct and indirect subsidiaries, including American Multi-Cinema, Inc. and its subsidiaries, (collectively with Holdings, unless the context otherwise requires, the “Company” or “AMC”), is principally involved in the theatrical exhibition business and owns, operates or has interests in theatres located in the United States and Europe. Stock Split and Reverse Stock Split On August 24, 2023, the Company effectuated a reverse stock split at a ratio of one one Accordingly, all references made to share, per share, unit, per unit, or common share amounts in the accompanying consolidated financial statements and applicable disclosures have been retroactively adjusted to reflect both the effects of the special dividend as a stock split and the subsequent reverse stock split. References made to AMC Preferred Equity Units have been retroactively adjusted to reflect the effect of the reverse stock split on their equivalent Common Stock shares. Liquidity. The Company’s cash burn rates are not sustainable long-term. In order to achieve sustainable net positive operating cash flows and long-term profitability, the Company believes that operating revenues will need to increase to levels in line with pre-COVID operating revenues. North American box office grosses were down approximately 16% for the nine months ended September 30, 2023, compared to the nine months ended September 30, 2019. Until such time as the Company is able to achieve positive operating cash flow, it is difficult to estimate the Company’s liquidity requirements, future cash burn rates, future operating revenues, and attendance levels. Depending on the Company’s assumptions regarding the timing and ability to achieve increased levels of operating revenue, the estimates of amounts of required liquidity vary significantly. ​ There can be no assurance that the operating revenues, attendance levels, and other assumptions used to estimate the Company’s liquidity requirements and future cash burn rates will be correct, and the ability to be predictive is uncertain due to limited ability to predict studio film release dates, the overall production and theatrical release levels, and success of individual titles. Additionally, the effects of labor stoppages, including but not limited to the Writers Guild of America strike that began on May 2, 2023 and ended on September 27, 2023, and the Screen Actors Guild – American Federation of Television and Radio Artists strike that began on July 14, 2023, cannot be reasonably estimated and may have a negative impact on the future film slate for exhibition, the Company’s future liquidity and cash burn rates. Further, there can be no assurances that the Company will be successful in generating the additional liquidity necessary to meet the Company’s obligations beyond twelve months from the issuance of these financial statements on terms acceptable to the Company or at all. The Company may, at any time and from time to time, seek to retire or purchase its outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as it may determine, and will depend on prevailing market conditions, its liquidity requirements, contractual restrictions and other factors. The amounts involved may be material and to the extent equity is used, dilutive. On December 22, 2022, the Company entered into a forward purchase agreement (the “Forward Purchase Agreement”) with Antara Capital LP (“Antara”) pursuant to which the Company agreed to (i) sell to Antara 10,659,511 AMC Preferred Equity Units for an aggregate purchase price of $75.1 million and (ii) simultaneously purchase from Antara $100.0 million aggregate principal amount of the Company’s 10%/12% Cash/PIK Toggle Second Lien Notes due 2026 in exchange for 9,102,619 AMC Preferred Equity Units. On February 7, 2023, the Company issued 19,762,130 AMC Preferred Equity Units to Antara in exchange for $75.1 million in cash and $100.0 million aggregate principal amount of the Company’s 10%/12% Cash/PIK Toggle Second Lien Notes due 2026. The Company recorded $193.7 million to stockholders’ deficit as a result of the transaction. The Company paid $1.4 million of accrued interest in cash upon exchange of the notes. See Note 7—Stockholders’ Equity for more information. During the nine months ended September 30, 2023, the Company raised gross proceeds of approximately $114.5 million and paid fees to a sales agent and incurred other third-party issuance costs of approximately $2.9 million and $8.7 million, respectively, through its at-the-market offering of approximately 7.1 million shares of its AMC Preferred Equity Units. The Company paid $11.5 million of other third-party issuance costs during the nine months ended September 30, 2023. During the nine months ended September 30, 2023, the Company raised gross proceeds of approximately $325.5 million and paid fees to a sales agent and incurred other third-party issuance costs of approximately $8.2 million and $0.5 million, respectively, through its at-the-market offering of 40.0 million shares of its Common Stock. The Company paid $0.1 million of other third-party issuance costs during the nine months ended September 30, 2023. See Note 7—Stockholders’ Equity for further information regarding the at-the-market offerings. The below table summarizes the cash debt repurchase transactions during the nine months ended September 30, 2023, including related party transactions with Antara, which was a related party from February 7, 2023 to August 25, 2023.

LEASES

LEASES
LEASES	NOTE 2—LEASES ​ The Company leases theatres and equipment under operating and finance leases. The Company typically does not believe that exercise of the renewal options is reasonably certain at the lease commencement and, therefore, considers the initial base term as the lease term. Lease terms vary but generally the leases provide for fixed and escalating rentals, contingent escalating rentals based on the Consumer Price Index and other indexes not to exceed certain specified amounts and variable rentals based on a percentage of revenues. The Company often receives contributions from landlords for renovations at existing locations. The Company records the amounts received from landlords as an adjustment to the right-of-use asset and amortizes the balance as a reduction to rent expense over the base term of the lease agreement. Equipment leases primarily consist of sight and sound and food and beverage equipment. ​ The Company received rent concessions from lessors that aided in mitigating the economic effects of COVID-19 during the pandemic. These concessions primarily consisted of rent abatements and the deferral of rent payments. Deferred lease payments were approximately $74.2 million as of September 30, 2023. In instances where there were no substantive changes to the lease terms, i.e., modifications that resulted in total payments of the modified lease being substantially the same or less than the total payments of the existing lease, the Company elected the relief as provided by the FASB staff related to the accounting for certain lease concessions. The Company elected not to account for these concessions as a lease modification, and therefore the Company has remeasured the related lease liability and right-of-use asset but did not reassess the lease classification or change the discount rate to the current rate in effect upon the remeasurement. The deferred lease payments have been recorded in the Company’s lease liabilities to reflect the change in the timing of payments. Those leases that did not meet the criteria for treatment under the FASB relief were evaluated as lease modifications. The deferred payment amounts for contractual rent amounts due and not paid are included in accounts payable in the condensed consolidated balance sheets and in change in accounts payable in the condensed consolidated statements of cash flows. In addition, the Company included deferred lease payments in operating lease right-of-use assets as a result of lease remeasurements. A summary of deferred payment amounts related to rent obligations for which payments were deferred to future periods is provided below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ ​ As of ​ ​ December 31, ​

Financial Covenants The Company believes its existing cash and cash equivalents, together with cash generated from operations, will be sufficient to comply with the minimum liquidity covenant requirement under its Senior Secured Revolving Credit Facility through the end of the covenant suspension period.

The current maturity date of the Senior Secured Revolving Credit Facility is April 22, 2024. The financial covenant applicable to the Senior Secured Revolving Credit Facility is tested as of the last day of any fiscal quarter for which financial statements have been (or were required to have been) delivered, thus the financial covenant has been effectively suspended through maturity of the Senior Secured Revolving Credit Facility. As of September 30, 2023, the Company was subject to a minimum liquidity requirement of $100 million as a condition to the financial covenant suspension period under the Credit Agreement. Thirteenth Amendment to Credit Agreement On June 23, 2023, the Company and Wilmington Savings Fund Society, FSB, as administrative agent, entered into the Thirteenth Amendment to the Credit Agreement, pursuant to which LIBOR, the benchmark rate upon which certain loans, commitments and/or other extensions of credit under the Credit Agreement incur interest, fees or other amounts, was replaced with Term SOFR, a benchmark rate reported by CME Group Benchmark Administration Limited that is based on the secured overnight financing rate. Term SOFR under the Credit Agreement is subject to a credit spread adjustment equal to 0.11448% per annum, 0.26161% per annum, and 0.42826% per annum for interest periods of one-month, three-months, or six-months or longer, respectively. The Thirteenth Amendment to the Credit Agreement became effective at 5:00 p.m. (New York time) on June 30, 2023. The Company elected to apply the optional expedients allowed under ASC 848 regarding the discontinuation of LIBOR and reference rate reform. Pursuant to ASC 848, the Thirteenth Amendment to the Credit Agreement was determined to be an insubstantial modification.

The Company intends to use the net proceeds, from the sale of AMC Preferred Equity Units pursuant to the Preferred Equity Units Equity Distribution Agreement to repay, refinance, redeem or repurchase the Company’s existing indebtedness (including expenses, accrued interest and premium, if any) and otherwise for general corporate purposes.

Special Meeting of Stockholders ​ The Company’s board of directors called a special meeting of the Company’s stockholders on March 14, 2023 (the “Special Meeting”). At the Special Meeting, the Company’s stockholders approved the following proposals: 1. Proposal No. 1: To approve an amendment to our Third Amended and Restated Certificate of Incorporation (“Certificate of Incorporation”) to increase the total number of authorized shares of Common Stock from 524,173,073 shares of Common Stock to 550,000,000 shares of Common Stock (the “Share Increase”); 2. Proposal No. 2: To approve an amendment to our Certificate of Incorporation to effectuate a reverse stock split at a ratio of one share of Common Stock for every ten shares of Common Stock, which together with the Share Increase, shall permit the full conversion of all outstanding shares of Series A Preferred Stock into shares of Common Stock (the “Reverse Stock Split” and collectively with the Share Increase, the “Charter Amendments”); and 3. Proposal No. 3: To approve one or more adjournments of the Special Meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Special Meeting to approve and adopt the Charter Amendments. ​ Each of the Share Increase and the Reverse Stock Split were cross-conditioned on the approval of the other, such that approval of both proposals was required for each of them to take effect. ​ Shareholder Litigation ​ Two putative stockholder class actions were filed in the Delaware Chancery Court that assert a breach of fiduciary duty against certain of the Company’s directors and a claim for breach of 8 Del. C This litigation prevented the Company from immediately implementing the Charter Amendments. On April 2, 2023, the parties entered into a binding settlement term sheet to settle the litigation and allow implementation of the Charter Amendments. On August 11, 2023, the Delaware Chancery Court approved the settlement and on Monday, August 21, 2023, the Delaware Supreme Court confirmed the ruling of the Chancery Court. Pursuant to the settlement term sheet, record holders of Common Stock at the close of business on August 24, 2023, after giving effect to the Reverse Stock Split, but prior to the conversion of AMC Preferred Equity Units into Common Stock (“Settlement Payment Recipients”), received a payment of one Charter Amendments and AMC Preferred Equity Unit Conversion Each AMC Preferred Equity Unit was a depositary share and represented an interest in a share of Series A Convertible Participating Preferred Stock evidenced by a depositary receipt pursuant to a deposit agreement. Each AMC Preferred Equity Unit was designed to have the same economic and voting rights as a share of Common Stock. On August 14, 2023, the Company filed an amendment to its Certificate of Incorporation to effectuate the Charter Amendments as of August 24, 2023. The Charter Amendments permitted the conversion of all of the Company’s outstanding AMC Preferred Equity Units into shares of Common Stock (the “Conversion”). On August 25, 2023, 99,540,642 shares of Common Stock were issued as part of the Conversion. On August 25, 2023, AMC Preferred Equity Units ceased trading and were subsequently delisted from the NYSE. On August 25, 2023, the Company filed a Certificate of Elimination of Series A Convertible Participating Preferred Stock with the Secretary of State of Delaware that eliminated the Series A Convertible Participating Preferred Stock from the Company’s Certificate of Incorporation. As of September 30, 2023, the Company has 50,000,000 authorized shares of preferred stock. AMC’s Board of Directors approved equitable adjustments to all outstanding awards under the 2013 Equity Incentive Plan subsequent to the effectiveness of the Charter Amendments. The outstanding awards were proportionally adjusted consistent with the ratio used for the Reverse Stock Split and all awards previously convertible into AMC Preferred Equity Units are now convertible into Common Stock.

On August 19, 2022, the Compensation Committee approved an adjustment to the 2013 Equity Incentive Plan to entitle each participant one AMC Preferred Equity Unit and one share of Common Stock for each restricted stock unit (“RSU”) or performance stock unit (“PSU”) for awards granted prior to the AMC Preferred Equity Unit special dividend. The Company determined that this modification was a Type 1 (probable-to-probable) modification that did not increase the fair value of the award and therefore did not require additional stock-based compensation expense to be recognized. Special Awards ​ On February 23, 2023, AMC’s Board of Directors approved special awards in lieu of vesting of the 2022 PSU awards. The special awards were accounted for as modification to the 2022 PSU awards which lowered the Adjusted EBITDA and free cash flow performance targets such that 200% vesting was achieved for both tranches. This modification resulted in the immediate additional vesting of 238,959 Common Stock 2022 PSUs and 238,959 AMC Preferred Equity Unit 2022 PSUs. This was treated as a Type 3 modification (improbable-to-probable) which requires the Company to recognize additional stock compensation expense based on the modification date fair values of the Common Stock PSUs and AMC Preferred Equity Units PSUs of $14.9 million and $5.3 million, respectively. During the nine months ended September 30, 2023, the Company recognized $20.2 million of stock compensation expense related to these awards. Awards Granted in 2023 ​ During the nine months ended September 30, 2023, AMC’s Board of Directors approved awards of stock, RSUs, and PSUs to certain of the Company’s employees and directors under the 2013 Equity Incentive Plan. Each RSU or PSU is convertible into one share of Common Stock upon vesting. Each RSU and PSU held by a participant as of a dividend record date is entitled to a dividend equivalent equal to the amount paid with respect to one share of Common Stock underlying the unit. Any such accrued dividend equivalents are paid to the holder only upon vesting of the units. Each unit represents the right to receive one share of Common Stock at a future date. The Company’s Board of Directors also granted awards to non-section 16 officers that are expected to be settled in cash. Upon vesting, participants receiving cash settlement shall receive an amount of cash equal to the closing price of an AMC Preferred Equity Unit multiplied by the number of underlying cash-based RSUs and PSUs awarded. Following the completion of the Charter Amendments, grantees will now receive an amount of cash equal to the closing price of Common Stock multiplied by the number of underlying cash-based RSUs and PSUs award. These awards have been classified as liabilities and are included within accrued expenses and other liabilities in the condensed consolidated balance sheets. The vesting requirements and vesting periods are identical to the equity classified awards described below. The Company recognizes expense related to these awards based on the fair value of the Common Stock shares, giving effect to the portion of services rendered during the requisite services period. As of September 30, 2023, there were 169,401 nonvested underlying Common Stock RSUs and PSUs related to awards granted to non-section 16 officers. There are 112,894 nonvested underlying Common Stock RSUs and PSUs (2023 Tranche Year) that are currently classified as liabilities and 56,507 nonvested underlying Common Stock PSUs (2024 & 2025 Tranche Year) which have not been granted for accounting purposes as the performance targets for the 2024 and 2025 PSU Tranche Years have yet to be established. The 2023 award agreements generally had the following features: ● Stock Award Agreement: During the nine months ended September 30, 2023, the Company granted awards of 8,555 fully vested shares of Common Stock and 15,370 AMC Preferred Equity Units to its independent members of AMC’s Board of Directors with a grant date fair value of $0.9 million. ● Restricted Stock Unit Award Agreement: During the nine months ended September 30, 2023, the Company granted 313,831 RSU awards to certain members of management with a grant date fair value of $12.0 million. The Company records stock-based compensation expense on a straight-line recognition method over the requisite vesting period. The RSUs vest over three years , with one-third vesting each year. These RSUs will be settled within 30 days of vesting. ● Performance Stock Unit Award Agreement: During the nine months ended September 30, 2023, total PSUs of 287,664 were awarded (“2023 PSU award”) to certain members of management and executive officers, with the total PSUs divided into three separate year tranches, with each tranche allocated to a fiscal year within the performance period (“Tranche Year”). The PSUs within each Tranche Year are further divided between two performance targets; the Adjusted EBITDA performance target and free cash flow performance target. The 2023 PSU awards will vest based on achieving 80% to 120% of the performance targets, with the corresponding vested unit amount ranging from 50% to 200% . If the performance targets are met at 100% , the 2023 PSU awards will vest at 287,664 units in the aggregate. No PSUs will vest for each Tranche Year if the Company does not achieve 80% of the Tranche Year’s Adjusted EBITDA and free cash flow targets. The Compensation Committee establishes the annual performance targets at the beginning of each year. Therefore, the grant date (and fair value measurement date) for each Tranche Year is the date at the beginning of each year when a mutual understanding of the key terms and conditions are reached per ASC 718, Compensation – Stock compensation. The 2023 PSU award grant date fair value for the 2023 Tranche Year award of 95,883 units was $3.9 million, the 2022 PSU award grant date fair value for the 2023 Tranche Year award of 46,192 units was $1.9 million, and the 2021 PSU award grant date fair value for the 2023 Tranche Year Award of 160,280 units was $6.8 million, measured using performance targets at 100%. The following table represents the equity classified nonvested RSU and PSU activity for the nine months ended September 30, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ Common Stock ​ Grant Date ​ ​ RSUs and PSUs (3) ​ Fair Value Nonvested at January 1, 2023 ​ 626,195 ​ $ 59.14 Granted ​ 616,186 ​ ​ 39.99 Granted - Special Award ​ 477,918 ​ ​ 42.25 Vested ​ (222,920) ​ ​ 57.43 Vested - Special Award ​ (257,945) ​ ​ 42.18 Forfeited ​ (26,036) ​ ​ 44.44 Cancelled ​ (150,755) ​ ​ 60.14 Cancelled - Special Award ​ (219,973) ​ ​ 42.34 Nonvested at September 30, 2023 ​ 842,670 ​ $ 45.87 Tranche Years 2024 and 2025 awarded under the 2023 PSU award and Tranche Year 2024 awarded under the 2022 PSU award with grant date fair values to be determined in years 2024 and 2025, respectively ​ 228,199 ​ ​ ​ Total Nonvested at September 30, 2023 ​ 1,070,869 ​ ​ ​ (1) The number of PSU shares granted under the Tranche Year 2023 assumes the Company will attain a performance target at 100% for the Adjusted EBITDA target and 100% for the free cash flow target.

INCOME TAXES

INCOME TAXES	9 Months Ended

INCOME TAXES
INCOME TAXES	NOTE 8—INCOME TAXES The Company’s worldwide effective income tax rate is based on actual income (loss), statutory rates, valuation allowances against deferred tax assets and tax planning opportunities available in the various jurisdictions in which it operates. The Company is using a discrete income tax calculation for the three and nine months ended September 30, 2023 due to the lingering effects of the COVID-19 pandemic and ongoing labor stoppages on the industry. Historically, for interim financial reporting, the Company estimated the worldwide annual income tax rate based on projected taxable income (loss) for the full year and recorded a quarterly income tax provision or benefit in accordance with the anticipated annual rate, adjusted for discrete items, if any. The Company will return to the historic approach of computing quarterly tax expense based on an annual effective rate in the future interim period when more reliable estimates of annual income become available. The Company recognizes income tax-related interest expense and penalties as income tax expense and general and administrative expense, respectively. The Company evaluates its deferred tax assets each period to determine if a valuation allowance is required based on whether it is “more likely than not” that some portion of the deferred tax assets would not be realized. The ultimate realization of these deferred tax assets is dependent upon the generation of sufficient taxable income during future periods on a federal, state, and foreign jurisdiction basis. The Company conducts its evaluation by considering all available positive and negative evidence, including historical operating results, forecasts of future profitability, the duration of statutory carryforward periods, and the outlooks for the U.S. motion picture and broader economy, among others. A valuation allowance is recorded against the Company’s U.S. deferred tax assets and most of the Company’s international deferred tax assets as the Company has determined the realization of these assets does not meet the more likely than not criteria. The effective tax rate for the nine months ended September 30, 2023 reflects the impact of these valuation allowances against U.S. and international deferred tax assets generated during the period. The actual effective rate for the nine months ended September 30, 2023 was (2.2)%. The Company’s consolidated tax rate for the nine months ended September 30, 2023 differs from the U.S. statutory tax rate primarily due to the valuation allowances in U.S. and foreign jurisdictions, foreign tax rate differences, federal and state tax credits, permanent differences and other discrete items. At September 30, 2023 and December 31, 2022, the Company has recorded net deferred tax liabilities of $32.8 million and $32.1 million, respectively. Utilization of the Company’s net operating loss carryforwards, disallowed business interest carryforwards and other tax attributes became subject to the Section 382 ownership change limitation due to changes in the Company’s stock ownership on January 27, 2021. The Company does not believe, however, that tax attributes generated prior to this event are significantly impacted by Section 382.

OPERATING SEGMENTS.
OPERATING SEGMENTS	NOTE 10—OPERATING SEGMENTS ​ The Company reports information about operating segments in accordance with ASC 280-10, Segment Reporting, which requires financial information to be reported based on the way management organizes segments within a company for making operating decisions and evaluating performance. The Company has identified two reportable segments and reporting units for its theatrical exhibition operations, U.S. markets and International markets. The International markets reportable segment has operations in or partial interest in theatres in the United Kingdom, Germany, Spain, Italy, Ireland, Portugal, Sweden, Finland, Norway, and Denmark. On December 30, 2022, the Company entered into an agreement to sell its 10.0% investment Saudi Cinema Company, LLC for SAR 112.5 million ($30.0 million), subject to certain closing conditions. On January 24, 2023, the Saudi Ministry of Commerce recorded the sale of equity and the Company received the proceeds on January 25, 2023. See Note 5—Investments for further information. Each segment’s revenue is derived from admissions, food and beverage sales and other ancillary revenues, primarily screen advertising, AMC Stubs® membership fees and other loyalty programs, ticket sales, gift card income and exchange ticket income. The measure of segment profit and loss the Company uses to evaluate performance and allocate its resources is Adjusted EBITDA, as defined in the reconciliation table below. The Company does not report asset information by segment because that information is not used to evaluate the performance of or allocate resources between segments. Below is a breakdown of select financial information by reportable operating segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended Revenues (In millions) September 30, 2023 ​ September 30, 2022 ​ September 30, 2023 September 30, 2022 U.S. markets ​ $ 1,063.9 ​ $ 753.3 ​ $ 2,855.8 $ 2,224.3 International markets ​ ​ 342.0 ​ ​ 215.1 ​ ​ 852.4 ​ 696.2 Total revenues ​ $ 1,405.9 ​ $ 968.4 ​ $ 3,708.2 $ 2,920.5 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended Adjusted EBITDA (In millions) September 30, 2023 September 30, 2022 ​ September 30, 2023 September 30, 2022 U.S. markets ​ $ 150.6 ​ $ 1.2 ​ $ 336.3 ​ $ 52.2 International markets ​ ​ 43.1 ​ ​ (14.1) ​ ​ 47.0 ​ ​ (20.1) Total Adjusted EBITDA ​ $ 193.7 ​ $ (12.9) ​ $ 383.3 ​ $ 32.1 (1) The Company presents Adjusted EBITDA as a supplemental measure of its performance.

The measure of segment profit and loss the Company uses to evaluate performance and allocate its resources is Adjusted EBITDA, which is broadly consistent with how Adjusted EBITDA is defined in the Company’s debt indentures. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended Capital Expenditures (In millions) September 30, 2023 September 30, 2022 ​ September 30, 2023 September 30, 2022 U.S. markets ​ $ 40.8 ​ $ 40.1 ​ $ 112.2 ​ $ 91.5 International markets ​ ​ 16.7 ​ ​ 14.4 ​ ​ 41.3 ​ ​ 38.2 Total capital expenditures ​ $ 57.5 ​ $ 54.5 ​ $ 153.5 ​ $ 129.7 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ As of Long-term assets, net (In millions) ​ September 30, 2023 ​ December 31, 2022 U.S. markets ​ $ 5,854.1 ​ $ 6,135.9 International markets ​ ​ 1,958.9 ​ ​ 2,097.6 Total long-term assets ​ $ 7,813.0 ​ $ 8,233.5 (1) Long-term assets are comprised of property, net, operating lease right-of-use assets, intangible assets, goodwill, deferred tax assets, net and other long-term assets. ​ The following table sets forth a reconciliation of net loss to Adjusted EBITDA: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended (In millions) ​ September 30, 2023 ​ September 30, 2022 September 30, 2023 ​ September 30, 2022 Net earnings (loss) ​ $ 12.3 ​ $ (226.9) ​ $ (214.6) ​ $ (685.9) Plus: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Income tax provision ​ 2.3 ​ 1.8 ​ 4.6 ​ 2.5 Interest expense ​ 103.7 ​ 95.7 ​ 307.4 ​ 278.4 Depreciation and amortization ​ 88.7 ​ 96.9 ​ 279.1 ​ 293.0 Certain operating expense ​ 3.8 ​ 4.3 ​ 4.0 ​ 10.5 Equity in (earnings) loss of non-consolidated entities ​ (3.1) ​ (2.8) ​ (5.3) ​ 3.3 Cash distributions from non-consolidated entities ​ 2.2 ​ 3.4 ​ 3.9 ​ 5.0 Attributable EBITDA ​ ​ 1.4 ​ ​ 0.1 ​ ​ 1.6 ​ ​ 0.1 Investment expense (income) ​ (3.0) ​ 18.3 ​ (11.4) ​ 12.2 Other expense (income) ​ (14.1) ​ 6.2 ​ (1.4) ​ 110.9 Other non-cash rent benefit ​ ​ (8.4) ​ ​ (6.6) ​ ​ (27.0) ​ ​ (20.6) General and administrative — unallocated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Merger, acquisition and other costs ​ 0.7 ​ 0.3 ​ 1.5 ​ 0.4 Stock-based compensation expense ​ 7.2 ​ (3.6) ​ 40.9 ​ 22.3 Adjusted EBITDA ​ $ 193.7 ​ $ (12.9) ​ $ 383.3 ​ $ 32.1 (1) Amounts represent preopening expense related to temporarily closed screens under renovation, theatre and other closure expense for the permanent closure of screens, including the related accretion of interest, disposition of assets and other non-operating gains or losses included in operating expenses. The Company has excluded these items as they are non-cash in nature or are non-operating in nature. (2) Includes U.S. non-theatre distributions from equity method investments and International non- theatre distributions from equity method investments to the extent received. The Company believes including cash distributions is an appropriate reflection of the contribution of these investments to the Company’s operations. (3) Attributable EBITDA includes the EBITDA from equity investments in theatre operators in certain International markets. See below for a reconciliation of the Company’s equity in loss of non-consolidated entities to attributable EBITDA. Because these equity investments in theatre operators are in regions where the Company holds a significant market share, the Company believes attributable EBITDA is more indicative of the performance of these equity investments and management uses this measure to monitor and evaluate these equity investments. The Company also provides services to these theatre operators including information technology systems, certain on-screen advertising services and the Company’s gift card and package ticket program. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended (In millions) ​ September 30, 2023 ​ September 30, 2022 September 30, 2023 ​ September 30, 2022 Equity in (earnings) loss of non-consolidated entities ​ $ (3.1) ​ $ (2.8) ​ $ (5.3) ​ $ 3.3 Less: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity in (earnings) of non-consolidated entities excluding International theatre joint ventures ​ ​ (2.1) ​ ​ (3.5) ​ ​ (4.7) ​ ​ (3.1) Equity in earnings (loss) of International theatre joint ventures ​ ​ 1.0 ​ ​ (0.7) ​ ​ 0.6 ​ ​ (6.4) Income tax provision (benefit) ​ ​ 0.1 ​ ​ 0.1 ​ ​ (0.1) ​ ​ 0.1 Investment expense (income) ​ ​ (0.2) ​ ​ — ​ ​ (0.1) ​ ​ 0.2 Interest expense ​ ​ 0.1 ​ ​ — ​ ​ 0.2 ​ ​ — Impairment of long-lived assets ​ ​ — ​ ​ — ​ ​ — ​ ​ 4.2 Depreciation and amortization ​ ​ 0.4 ​ ​ 0.7 ​ ​ 1.0 ​ ​ 2.0 Attributable EBITDA ​ $ 1.4 ​ $ 0.1 ​ $ 1.6 ​ $ 0.1 ​ (4) Investment expense (income) during the three months ended September 30, 2023 primarily includes appreciation in estimated fair value of the Company’s investment in common shares of Hycroft of $(0.1) million, deterioration in estimated fair value of the Company’s investment in warrants to purchase common shares of Hycroft of $0.8 million and interest income of $(3.7) million.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	NOTE 11—COMMITMENTS AND CONTINGENCIES The Company, in the normal course of business, is a party to various ordinary course claims from vendors (including food and beverage suppliers and film distributors), landlords, competitors, and other legal proceedings. If management believes that a loss arising from these actions is probable and can reasonably be estimated, the Company records the amount of the loss or the minimum estimated liability when the loss is estimated using a range and no point is more probable than another. As additional information becomes available, any potential liability related to these actions is assessed and the estimates are revised, if necessary. Management believes that the ultimate outcome of such matters discussed below, individually and in the aggregate, will not have a material adverse effect on the Company’s financial position or overall trends in results of operations. However, litigation and claims are subject to inherent uncertainties and unfavorable outcomes can occur. An unfavorable outcome might include monetary damages. If an unfavorable outcome were to occur, there exists the possibility of a material adverse impact on the results of operations in the period in which the outcome occurs or in future periods. On January 12, 2018 and January 19, 2018, two putative federal securities class actions, captioned Hawaii Structural Ironworkers Pension Trust Fund v. AMC Entertainment Holdings, Inc., et al., Case No. 1:18-cv-00299-AJN (the “Hawaii Action”), and Nichols v. AMC Entertainment Holdings, Inc., et al., Case No. 1:18-cv-00510-AJN (the “Nichols Action,” and together with the Hawaii Action, the “Actions”), respectively, were filed against the Company in the U.S. District Court for the Southern District of New York.

The Company and the other defendants continue to expressly deny any liability or wrongdoing with respect to the matters alleged in the Actions. On November 1, 2021, the parties to the Actions signed a stipulation of settlement, which memorialized the terms of the agreement in principle, and which the plaintiffs filed with the court. Also on November 1, 2021, plaintiffs filed a motion to preliminarily approve the settlement. On November 8, 2021, the court preliminarily approved the settlement, approved the form of notice to be disseminated to class members, and scheduled a final fairness hearing on the settlement for February 10, 2022.

On June 14, 2023, the parties to the Gantulga, Kenna, Manuel, Dinkevich, and Lyon Actions signed a stipulation of settlement, which subject to the approval of the court, will resolve those actions. As consideration for the proposed settlement, the Company agreed to certain corporate governance reforms. The Company also agreed to the payment of a $1.0 million fee and expense award to the plaintiffs’ attorneys to be paid by the Company’s director’s and officer’s insurance carriers. Defendants agreed to the settlement solely to eliminate the burden, expense, and uncertainties inherent in further litigation. Defendants have denied, and continue to deny, all allegations of wrongdoing, fault, liability, or damages with respect to the matters alleged in the Gantulga, Kenna, Manuel, Dinkevich, and Lyon Actions.

EARNINGS (LOSS) PER SHARE
EARNINGS (LOSS) PER SHARE	NOTE 12—EARNINGS (LOSS) PER SHARE ​ On August 4, 2022, the Company announced that its Board of Directors declared a special dividend of one AMC Preferred Equity Unit for each share of Common Stock outstanding at the close of business on August 15, 2022, the record date. The dividend was paid at the close of business on August 19, 2022 to investors who held Common Stock as of August 22, 2022, the ex-dividend date. Due to the characteristics of the AMC Preferred Equity Units, the special dividend had the effect of a stock split pursuant to ASC 505-20-25-4. On August 24, 2023, the Company effectuated a reverse stock split at a ratio of one one Accordingly, all references made to share, per share, unit, per unit, or common share amounts in the accompanying consolidated financial statements and applicable disclosures have been retroactively adjusted to reflect both the effects of the special dividend as a stock split and the subsequent reverse stock split. References made to AMC Preferred Equity Units have been retroactively adjusted to reflect the effect of the reverse stock split on their equivalent Common Stock shares. Basic earnings (loss) per share is computed by dividing net earnings (loss) by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share includes the effects of unvested RSUs with a service condition only and unvested contingently issuable PSUs that have service and performance conditions, if dilutive.

Unvested RSUs of 467,353 and 548,419 for the three and nine months ended September 30, 2023, respectively were not included in the computation of diluted earnings (loss) per share because they would be anti-dilutive. Unvested RSUs of 542,815 for the three and nine months ended September 30, 2022 were not included in the computation of diluted loss per share because they would be anti-dilutive. Unvested PSUs are subject to performance conditions and are included in diluted earnings per share, if dilutive, based on the number of shares, if any, that would be issuable under the terms of the Company’s 2013 Equity Incentive Plan if the end of the reporting period were the end of the contingency period. Unvested PSUs of 192,052 and 294,251 for the three and nine months ended September 30, 2023, respectively were not included in the computation of diluted earnings (loss) per share because they would not be issuable if the end of the reporting period were the end of the contingency period or they would be anti-dilutive. Unvested PSUs of 283,809 at certain performance targets for the three and nine months ended September 30, 2022, were not included in the computation of diluted loss per share because they would not be issuable if the end of the reporting period were the end of the contingency period or they would be anti-dilutive.

Liquidity	Liquidity. The Company’s cash burn rates are not sustainable long-term. In order to achieve sustainable net positive operating cash flows and long-term profitability, the Company believes that operating revenues will need to increase to levels in line with pre-COVID operating revenues. North American box office grosses were down approximately 16% for the nine months ended September 30, 2023, compared to the nine months ended September 30, 2019. Until such time as the Company is able to achieve positive operating cash flow, it is difficult to estimate the Company’s liquidity requirements, future cash burn rates, future operating revenues, and attendance levels. Depending on the Company’s assumptions regarding the timing and ability to achieve increased levels of operating revenue, the estimates of amounts of required liquidity vary significantly. ​ There can be no assurance that the operating revenues, attendance levels, and other assumptions used to estimate the Company’s liquidity requirements and future cash burn rates will be correct, and the ability to be predictive is uncertain due to limited ability to predict studio film release dates, the overall production and theatrical release levels, and success of individual titles. Additionally, the effects of labor stoppages, including but not limited to the Writers Guild of America strike that began on May 2, 2023 and ended on September 27, 2023, and the Screen Actors Guild – American Federation of Television and Radio Artists strike that began on July 14, 2023, cannot be reasonably estimated and may have a negative impact on the future film slate for exhibition, the Company’s future liquidity and cash burn rates. Further, there can be no assurances that the Company will be successful in generating the additional liquidity necessary to meet the Company’s obligations beyond twelve months from the issuance of these financial statements on terms acceptable to the Company or at all. The Company may, at any time and from time to time, seek to retire or purchase its outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as it may determine, and will depend on prevailing market conditions, its liquidity requirements, contractual restrictions and other factors. The amounts involved may be material and to the extent equity is used, dilutive. On December 22, 2022, the Company entered into a forward purchase agreement (the “Forward Purchase Agreement”) with Antara Capital LP (“Antara”) pursuant to which the Company agreed to (i) sell to Antara 10,659,511 AMC Preferred Equity Units for an aggregate purchase price of $75.1 million and (ii) simultaneously purchase from Antara $100.0 million aggregate principal amount of the Company’s 10%/12% Cash/PIK Toggle Second Lien Notes due 2026 in exchange for 9,102,619 AMC Preferred Equity Units. On February 7, 2023, the Company issued 19,762,130 AMC Preferred Equity Units to Antara in exchange for $75.1 million in cash and $100.0 million aggregate principal amount of the Company’s 10%/12% Cash/PIK Toggle Second Lien Notes due 2026. The Company recorded $193.7 million to stockholders’ deficit as a result of the transaction. The Company paid $1.4 million of accrued interest in cash upon exchange of the notes. See Note 7—Stockholders’ Equity for more information. During the nine months ended September 30, 2023, the Company raised gross proceeds of approximately $114.5 million and paid fees to a sales agent and incurred other third-party issuance costs of approximately $2.9 million and $8.7 million, respectively, through its at-the-market offering of approximately 7.1 million shares of its AMC Preferred Equity Units. The Company paid $11.5 million of other third-party issuance costs during the nine months ended September 30, 2023. During the nine months ended September 30, 2023, the Company raised gross proceeds of approximately $325.5 million and paid fees to a sales agent and incurred other third-party issuance costs of approximately $8.2 million and $0.5 million, respectively, through its at-the-market offering of 40.0 million shares of its Common Stock. The Company paid $0.1 million of other third-party issuance costs during the nine months ended September 30, 2023.

The Company defines Adjusted EBITDA as net earnings (loss) plus (i) income tax provision (benefit), (ii) interest expense and (iii) depreciation and amortization, as further adjusted to eliminate the impact of certain items that the Company does not consider indicative of the Company’s ongoing operating performance and to include attributable EBITDA from equity investments in theatre operations in International markets and any cash distributions of earnings from its other equity method investees. The measure of segment profit and loss the Company uses to evaluate performance and allocate its resources is Adjusted EBITDA, which is broadly consistent with how Adjusted EBITDA is defined in the Company’s debt indentures. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended Capital Expenditures (In millions) September 30, 2023 September 30, 2022 ​ September 30, 2023 September 30, 2022 U.S. markets ​ $ 40.8 ​ $ 40.1 ​ $ 112.2 ​ $ 91.5 International markets ​ ​ 16.7 ​ ​ 14.4 ​ ​ 41.3 ​ ​ 38.2 Total capital expenditures ​ $ 57.5 ​ $ 54.5 ​ $ 153.5 ​ $ 129.7 ​

The Company has excluded these items as they are non-cash in nature or are non-operating in nature. (2) Includes U.S. non-theatre distributions from equity method investments and International non- theatre distributions from equity method investments to the extent received. The Company believes including cash distributions is an appropriate reflection of the contribution of these investments to the Company’s operations. (3) Attributable EBITDA includes the EBITDA from equity investments in theatre operators in certain International markets. See below for a reconciliation of the Company’s equity in loss of non-consolidated entities to attributable EBITDA. Because these equity investments in theatre operators are in regions where the Company holds a significant market share, the Company believes attributable EBITDA is more indicative of the performance of these equity investments and management uses this measure to monitor and evaluate these equity investments. The Company also provides services to these theatre operators including information technology systems, certain on-screen advertising services and the Company’s gift card and package ticket program. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended (In millions) ​ September 30, 2023 ​ September 30, 2022 September 30, 2023 ​ September 30, 2022 Equity in (earnings) loss of non-consolidated entities ​ $ (3.1) ​ $ (2.8) ​ $ (5.3) ​ $ 3.3 Less: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity in (earnings) of non-consolidated entities excluding International theatre joint ventures ​ ​ (2.1) ​ ​ (3.5) ​ ​ (4.7) ​ ​ (3.1) Equity in earnings (loss) of International theatre joint ventures ​ ​ 1.0 ​ ​ (0.7) ​ ​ 0.6 ​ ​ (6.4) Income tax provision (benefit) ​ ​ 0.1 ​ ​ 0.1 ​ ​ (0.1) ​ ​ 0.1 Investment expense (income) ​ ​ (0.2) ​ ​ — ​ ​ (0.1) ​ ​ 0.2 Interest expense ​ ​ 0.1 ​ ​ — ​ ​ 0.2 ​ ​ — Impairment of long-lived assets ​ ​ — ​ ​ — ​ ​ — ​ ​ 4.2 Depreciation and amortization ​ ​ 0.4 ​ ​ 0.7 ​ ​ 1.0 ​ ​ 2.0 Attributable EBITDA ​ $ 1.4 ​ $ 0.1 ​ $ 1.6 ​ $ 0.1 ​ (4) Investment expense (income) during the three months ended September 30, 2023 primarily includes appreciation in estimated fair value of the Company’s investment in common shares of Hycroft of $(0.1) million, deterioration in estimated fair value of the Company’s investment in warrants to purchase common shares of Hycroft of $0.8 million and interest income of $(3.7) million.
