Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business organization	Business organization Planet Fitness, Inc. (the “Company”), through its subsidiaries, is a franchisor and operator of fitness centers, with approximately 19.6 million members and 2,599 owned and franchised locations (referred to as stores) in all 50 states, the District of Columbia, Puerto Rico, Canada, Panama, Mexico and Australia as of March 31, 2024. The Company serves as the reporting entity for its various subsidiaries that operate three distinct lines of business: • Licensing and selling franchises under the Planet Fitness trade name; • Owning and operating fitness centers under the Planet Fitness trade name; and • Selling fitness-related equipment to franchisee-owned stores. In 2012 investment funds affiliated with TSG Consumer Partners, LLC (“TSG”), purchased interests in Pla-Fit Holdings. The Company was formed as a Delaware corporation on March 16, 2015 for the purpose of facilitating an initial public offering (the “IPO”) and related transactions in order to carry on the business of Pla-Fit Holdings, LLC and its subsidiaries (“Pla-Fit Holdings”). As of August 5, 2015, in connection with the recapitalization transactions, the Company became the sole managing member and holder of 100% of the voting power of Pla-Fit Holdings. Pla-Fit Holdings owns 100% of Planet Intermediate, LLC, which has no operations but is the 100% owner of Planet Fitness Holdings, LLC, a franchisor and operator of fitness centers. With respect to the Company, Pla-Fit Holdings and Planet Intermediate, LLC, each entity owns nothing other than the respective entity below it in the corporate structure and each entity has no other material operations. The Company is a holding company whose principal asset is a controlling equity interest in the membership units (“Holdings Units”) in Pla-Fit Holdings. As the sole managing member of Pla-Fit Holdings, the Company operates and controls all of the business and affairs of Pla-Fit Holdings, and through Pla-Fit Holdings, conducts its business. As a result, the Company consolidates Pla-Fit Holdings’ financial results and reports a non-controlling interest related to the portion of Holdings Units not owned by the Company. As of March 31, 2024, the Company held 100.0% of the voting interest and approximately 98.8% of the economic interest in Pla-Fit Holdings and the owners of Holdings Units other than the Company (the “Continuing LLC Owners”) held the remaining 1.2% economic interest in Pla-Fit Holdings. As future exchanges of Holdings Units occur, the economic interest in Pla-Fit Holdings held by Planet Fitness, Inc. will increase.

Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of significant accounting policies (a) Basis of presentation and consolidation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented have been reflected. All significant intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023 are unaudited. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited financial statements at that date but does not include all of the disclosures required by GAAP. These interim condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on February 29, 2024. The Company’s significant interim accounting policies include the proportional recognition of national advertising fund expenses within interim periods. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year ending December 31, 2024. (b) Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Although these estimates are based on management’s knowledge of current events and actions it may undertake in the future, they may ultimately differ from actual results. Significant areas where estimates and judgments are relied upon by management in the preparation of the condensed consolidated financial statements include revenue recognition, valuation of equity-based compensation awards, valuation of assets and liabilities acquired in business combinations, the evaluation of the recoverability of goodwill and long-lived assets, including intangible assets, allowance for expected credit losses, the present value of lease liabilities, income taxes, including deferred tax assets and liabilities, and the liability for the Company’s tax benefit arrangements. (c) Fair Value ASC 820, Fair Value Measurements and Disclosures , establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows: Level 1—Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2—Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Certain of the Company’s financial instruments, including cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and other current liabilities are carried at cost, which approximates their fair value because of their short-term nature. See Note 3 for investments that are measured at fair value on a recurring basis. The carrying value and estimated fair value of long-term debt were as follows: March 31, 2024 December 31, 2023 Carrying value Estimated fair value (1) Carrying value Estimated fair value (1) Long-term debt (1) $ 1,999,250 $ 1,851,357 $ 2,004,438 $ 1,829,286 (1) The estimated fair value of the Company’s fixed rate long-term debt is estimated primarily based on current bid prices for the long-term debt. Judgment is required to develop these estimates. As such, the fair value of long-term debt is classified within Level 2, as defined under GAAP. (d) Recent accounting pronouncements The FASB issued ASU No. 2023-05, Business Combinations-Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement , in August 2023. The standard addresses the accounting for contributions made to a joint venture, upon formation, in a joint venture's separate financial statements. The new standard is effective prospectively for all joint ventures with a formation date on or after January 1, 2025. The Company will apply the standard to any relevant transactions subsequent to the adoption date. The FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosures , in November 2023. The standard expands reportable segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The new standard is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adoption on our financial disclosures. The FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures , in December 2023. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions and applies to all entities subject to income taxes. The new standard is effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of adoption on our financial disclosures.

For marketable securities with unrealized loss positions, the Company does not intend to sell these securities and it is more likely than not that the Company will hold these securities until maturity or a recovery of the cost basis and they are therefore all categorized as available for sale. No allowance for credit losses was recorded for these securities as of March 31, 2024. Held-to-maturity debt security As of March 31, 2024, the Company’s debt security investment consists of redeemable preferred shares that are accounted for as a held-to-maturity investment. The Company’s investment is measured at amortized cost within investments in the condensed consolidated balance sheets. The Company reviews its held-to-maturity securities for expected credit losses under ASC Topic 326, Financial Instruments – Credit Losses , on an ongoing basis. During the three months ended March 31, 2024 and 2023, the Company’s review of the investment indicated that an adjustment to its allowance for expected credit losses was necessary. The Company utilized probability-of-default (“PD”) and loss-given-default (“LGD”) methodologies to calculate the allowance for expected credit losses. The Company derived its estimates using historical lifetime loss information for assets with similar risk characteristics, adjusted for management’s expectations. Adjustments for management’s expectations were based on the investee’s recent financial results, current financial position, and forward-looking financial forecasts. Based upon its analysis, the Company recorded a credit loss expense of $475 and $255 for the three months ended March 31, 2024 and 2023, respectively, on the adjustment of its allowance for credit losses within other (income) expense, net on the condensed consolidated statements of operations. The amortized cost, including accrued dividends, of the Company’s held-to-maturity debt security investment was $30,871 and $30,343 and the allowance for expected credit losses was $18,164 and $17,689, as of March 31, 2024 and December 31, 2023, respectively. The amortized cost, net of the allowance for expected credit losses, approximates fair value. The Company recognized dividend income of $528 and $483 during the three months ended March 31, 2024 and 2023, respectively, within other income (expense), net on the condensed consolidated statements of operations. As of March 31, 2024, the Company’s held-to-maturity investment had a contractual maturity in 2026. A roll forward of the Company’s allowance for expected credit losses on its held-to-maturity investment is as follows: Three Months Ended March 31, 2024 2023 Beginning allowance for expected credit losses $ 17,689 $ 14,957 Loss on adjustment of allowance for expected credit losses 475 255 Write-offs, net of recoveries — — Ending allowance for expected credit losses $ 18,164 $ 15,212 Equity method investments For the following investments, the Company recorded its proportionate share of the investees’ earnings, prepared in accordance with GAAP, on a one-month lag, with an adjustment to eliminate unrealized profits on intra-entity sales, if any, and the amortization of basis differences, within losses from equity-method investments, net of tax on the condensed consolidated statements of operations. As of March 31, 2024, the Company determined that no impairment of its equity method investments existed. As of March 31, 2024 and December 31, 2023, the Company held a 21.8% ownership interest in Bravo Fit Holdings Pty Ltd, a franchisee of the Company and store operator in Australia, which is deemed to be a related party, for a total investment carrying value of $12,912 and $13,220, respectively. The difference between the carrying amount of the Company’s investment and the underlying amount of equity in net assets of the investment was $6,326 and $6,812 as of March 31, 2024 and December 31, 2023, respectively. These basis differences are attributable to intangible assets, which are being amortized on a straight-line basis over a weighted-average life of 9 years, and equity method goodwill. For the three months ended March 31, 2024 and 2023, the Company’s proportionate share of the earnings in accordance with the equity method was a loss of $308 and $265, respectively, which included amortization of basis difference of $66 and $65, respectively. As of March 31, 2024 and December 31, 2023, the Company held a 33.2% ownership interest in Planet Fitmex, LLC, a franchisee of the Company and store operator in Mexico, which is deemed to be a related party and classified as an equity method investment as a result of its organizational structure, for a total investment carrying value of $50,741 and $51,633, respectively. The difference between the carrying amount of the Company’s investment and the underlying amount of equity in net assets of the investment was $16,390 and $17,458 as of March 31, 2024 and December 31, 2023, respectively. This basis difference is attributable to intangible assets, which are being amortized on a straight-line basis over a weighted-average life of 9 years, and equity method goodwill. For the three months ended March 31, 2024, the Company’s proportionate share of the earnings in accordance with the equity method was a loss of $892, which included amortization of basis difference of $163.

Together, the Notes, 2018 Variable Funding Notes and 2022 Variable Funding Notes will be referred to as the “Securitized Senior Notes”. The Notes were issued in securitization transactions pursuant to which most of the Company’s domestic revenue-generating assets, consisting principally of franchise-related agreements, certain corporate-owned store assets, equipment supply agreements and intellectual property and license agreements for the use of intellectual property, were assigned to the Master Issuer and certain other limited-purpose, bankruptcy remote, wholly-owned indirect subsidiaries of the Company that act as guarantors of the Securitized Senior Notes and that have pledged substantially all of their assets to secure the Securitized Senior Notes. Interest and principal payments on the Notes are payable on a quarterly basis. The requirement to make such quarterly principal payments on the Notes is subject to certain financial conditions set forth in the Indenture. The legal final maturity date of the 2018 Class A-2-II Notes is in September 2048, but it is anticipated that, unless earlier prepaid to the extent permitted under the Indenture, the 2018 Class A-2-II Notes will be repaid in or prior to September 2025.

In connection with the issuance of the 2018 Notes, 2019 Notes, and 2022 Notes, the Company incurred debt issuance costs of $27,133, $10,577, and $16,193 respectively. The debt issuance costs are being amortized to interest expense through the Anticipated Repayment Dates of the Notes utilizing the effective interest rate method. The Securitized Senior Notes are subject to covenants and restrictions customary for transactions of this type, including (i) that the Master Issuer maintains specified reserve accounts to be used to make required payments in respect of the Securitized Senior Notes, (ii) provisions relating to optional and mandatory prepayments and the related payment of specified amounts, including specified make-whole payments in the case of the Notes under certain circumstances, (iii) certain indemnification payments in the event, among other things, the assets pledged as collateral for the Securitized Senior Notes are in stated ways defective or ineffective, (iv) a cap on non-securitized indebtedness of $50,000 (provided that the Company may incur non-securitized indebtedness in excess of such amount, subject to the leverage ratio cap described below, under certain conditions, including if the relevant lenders execute a non-disturbance agreement that acknowledges the bankruptcy-remote status of the Master Issuer and its subsidiaries and of their respective assets), (v) a leverage ratio cap incurrence test on the Company of 7.0x (calculated without regard for any indebtedness subject to the $50,000 cap) and (vi) covenants relating to recordkeeping, access to information and similar matters. Pursuant to a parent company support agreement, the Company has agreed to cause its subsidiary to perform each of its obligations (including any indemnity obligations) and duties under the Management Agreement and under the contribution agreements entered into in connection with the securitized financing facility, in each case as and when due. To the extent that such subsidiary has not performed any such obligation or duty within the prescribed time frame after such obligation or duty was required to be performed, the Company has agreed to either (i) perform such obligation or duty or (ii) cause such obligations or duties to be performed on the Company’s behalf. The Securitized Senior Notes are also subject to customary rapid amortization events provided for in the Indenture, including events tied to failure to maintain stated debt service coverage ratios, certain manager termination events, an event of default, and the failure to repay or refinance the Notes on the applicable scheduled Anticipated Repayment Dates. The Securitized Senior Notes are also subject to certain customary events of default, including events relating to non-payment of required interest, principal, or other amounts due on or with respect to the Securitized Senior Notes, failure to comply with covenants within certain time frames, certain bankruptcy events, breaches of specified representations and warranties, failure of security interests to be effective, and certain judgments. In accordance with the Indenture, certain cash accounts have been established with the Indenture trustee (the “Trustee”) for the benefit of the trustee and the noteholders, and are restricted in their use. The Company holds restricted cash which primarily represents cash collections held by the Trustee, interest, principal, and commitment fee reserves held by the Trustee related to the Securitized Senior Notes. As of March 31, 2024, the Company had restricted cash held by the Trustee of $46,190.

Equity [Abstract]
Stockholders' equity	Stockholders’ equity Pursuant to the exchange agreement between the Company and the Continuing LLC Owners, the Continuing LLC Owners (or certain permitted transferees thereof) have the right, from time to time and subject to the terms of the exchange agreement, to exchange their Holdings Units, along with a corresponding number of shares of Class B common stock, for shares of Class A common stock (or cash at the option of the Company) on a one-for-one basis, subject to customary conversion rate adjustments for stock splits, stock dividends, reclassifications and similar transactions. In connection with any exchange of Holdings Units for shares of Class A common stock by a Continuing LLC Owner, the number of Holdings Units held by the Company is correspondingly increased as it acquires the exchanged Holdings Units, and a corresponding number of shares of Class B common stock are canceled. During the three months ended March 31, 2024, certain existing holders of Holdings Units exercised their exchange rights and exchanged 326,073 Holdings Units for 326,073 newly-issued shares of Class A common stock. Simultaneously, and in connection with these exchanges, 326,073 shares of Class B common stock were surrendered by the holders of Holdings Units that exercised their exchange rights and canceled. Additionally, in connection with these exchanges, Planet Fitness, Inc. received 326,073 Holdings Units, increasing its total ownership interest in Pla-Fit Holdings. As a result of the above transactions, as of March 31, 2024: • Holders of Class A common stock owned 86,831,728 shares of Class A common stock, representing 98.8% of the voting power in the Company and, through the Company, 86,831,728 Holdings Units representing 98.8% of the economic interest in Pla-Fit Holdings; and • the Continuing LLC Owners collectively owned 1,071,094 Holdings Units, representing 1.2% of the economic interest in Pla-Fit Holdings, and 1,071,094 shares of Class B common stock, representing 1.2% of the voting power in the Company. Share repurchase program On November 4, 2022, the Company’s board of directors approved a share repurchase program of up to $500,000, which replaced the 2019 share repurchase program. During the three months ended March 31, 2024, the Company repurchased and retired 313,834 shares of Class A common stock for a total cost of $20,005. A share repurchase excise tax of $163 was also incurred. As of March 31, 2024, there is $354,965 remaining under the 2022 share repurchase program. The timing of purchases and amount of stock repurchased are subject to the Company’s discretion and dependent upon market and business conditions, the Company’s general working capital needs, stock price, applicable legal requirements and other factors. The ability to repurchase shares at any particular time is also subject to the terms of the Indenture governing the Securitized Senior Notes. Purchases may be effected through one or more open market transactions, privately negotiated transactions, transactions structured through investment banking institutions, or a combination of the foregoing. Preferred stock The Company had 50,000,000 shares of preferred stock authorized and none issued or outstanding as of March 31, 2024 and December 31, 2023.

Earnings Per Share [Abstract]
Earnings per share	Earnings per share Basic earnings per share of Class A common stock is computed by dividing net income attributable to Planet Fitness, Inc. by the weighted-average number of shares of Class A common stock outstanding. Diluted earnings per share of Class A common stock is computed by dividing net income attributable to Planet Fitness, Inc. by the weighted-average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive securities. Shares of the Company’s Class B common stock do not share in the earnings attributable to Planet Fitness, Inc. and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B common stock under the two-class method has not been presented. Shares of the Company’s Class B common stock are, however, considered potentially dilutive shares of Class A common stock because shares of Class B common stock, together with the related Holdings Units, are exchangeable into shares of Class A common stock on a one-for-one basis. The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings per share of Class A common stock: Three Months Ended March 31, 2024 2023 Numerator Net income $ 34,973 $ 24,769 Less: net income attributable to non-controlling interests 664 2,064 Net income attributable to Planet Fitness, Inc. $ 34,309 $ 22,705 Denominator Weighted-average shares of Class A common stock outstanding - basic 86,909,383 84,444,003 Effect of dilutive securities: Stock options 223,244 271,680 Restricted stock units 63,276 63,358 Performance stock units 26,178 7,654 Weighted-average shares of Class A common stock outstanding - diluted 87,222,081 84,786,695 Earnings per share of Class A common stock - basic $ 0.39 $ 0.27 Earnings per share of Class A common stock - diluted $ 0.39 $ 0.27 The number of weighted-average common stock equivalents excluded from the computation of diluted net income per share because either the effect would have been anti-dilutive, or the performance criteria related to the units had not yet been met, were as follows: Three Months Ended March 31, 2024 2023 Class B common stock 1,176,568 5,007,448 Stock options 554 196,209 Restricted stock units 2 — Performance stock units — 53 Total 1,177,124 5,203,710

Income Tax Disclosure [Abstract]
Income taxes	Income taxes The Company is the sole managing member of Pla-Fit Holdings, which is treated as a partnership for U.S. federal and certain state and local income taxes. As a partnership, Pla-Fit Holdings is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by Pla-Fit Holdings is passed through to and included in the taxable income or loss of its members, including the Company, on a pro-rata basis. Planet Fitness, Inc. is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to the allocable share of any taxable income of Pla-Fit Holdings. The Company’s effective tax rate was 28.4% and 27.6% for the three months ended March 31, 2024 and 2023, respectively, which differed from the U.S. federal statutory rate of 21% primarily due to state and local taxes, partially offset by income attributable to non-controlling interests. The Company is also subject to taxes in foreign jurisdictions. Net deferred tax assets of $498,173 and $502,544 as of March 31, 2024 and December 31, 2023, respectively, relate primarily to the tax effects of temporary differences in the book basis as compared to the tax basis of the investment in Pla-Fit Holdings as a result of the secondary offerings, other exchanges, recapitalization transactions and the IPO. As of March 31, 2024 and December 31, 2023, the total liability related to uncertain tax positions was $242 and $273, respectively. The Company recognizes accrued interest and penalties, if applicable, related to unrecognized tax benefits in income tax expense. Interest and penalties for the three months ended March 31, 2024 and 2023 were not material. Tax benefit arrangements The Company’s acquisition of Holdings Units in connection with the IPO and future and certain past exchanges of Holdings Units for shares of the Company’s Class A common stock (or cash at the option of the Company) are expected to produce and have produced favorable tax attributes. In connection with the IPO, the Company entered into two tax receivable agreements, pursuant to which, the Company is required to make payments to certain holders of equity interests or their successors-in-interest (“TRA Holders”). Under the first of those arrangements, the Company generally is required to pay certain existing and previous equity owners of Pla-Fit Holdings, LLC 85% of the applicable tax savings, if any, in U.S. federal and state income tax that the Company is deemed to realize as a result of certain tax attributes of their Holdings Units sold to the Company (or exchanged in a taxable sale) and that are created as a result of (i) the sales of their Holdings Units for shares of Class A common stock and (ii) tax benefits attributable to payments made under the tax receivable agreement (including imputed interest). Under the second tax receivable agreement, the Company generally is required to pay 85% of the amount of tax savings, if any, that the Company is deemed to realize as a result of the tax attributes of certain equity interests previously held by affiliates of TSG that resulted from TSG’s purchase of interests in Pla-Fit Holdings in 2012, and certain other tax benefits. Under both agreements, the Company generally retains the remaining 15% benefit of the applicable tax savings. In connection with the exchanges that occurred during the three months ended March 31, 2024 and 2023, 326,073 and 1,900,309 Holding Units, respectively, were redeemed by the Continuing LLC Owners for newly-issued shares of Class A common stock, resulting in an increase in the tax basis of the net assets of Pla-Fit Holdings. As a result of the change in the Company’s ownership percentage of Pla-Fit Holdings that occurred in conjunction with the exchanges and issuance of Holding Units, the Company recorded a decrease of $400 and $2,605 to net deferred tax assets, during the three months ended March 31, 2024 and 2023, respectively. As a result of these exchanges and other activity during the three months ended March 31, 2024 and 2023, the Company also recognized deferred tax assets in the amount of $7,519 and $50,823, respectively, and corresponding tax benefit arrangement liabilities of $2,694 and $2,315, respectively, representing approximately 85% of the tax benefits due to the TRA Holders for shares exchanged that were subject to tax benefit arrangements. The offset to the entries recorded in connection with exchanges was to additional paid in capital within stockholders’ deficit. The Company had a liability of $497,994 and $495,662 as of March 31, 2024 and December 31, 2023, respectively, related to its projected obligations under the tax benefit arrangements. Projected future payments under the tax benefit arrangements were as follows: Amount Remainder of 2024 $ 41,135 2025 50,385 2026 52,814 2027 48,624 2028 41,973 Thereafter 263,063 Total $ 497,994

Segment Reporting [Abstract]
Segments	Segments The Company has three reportable segments: (i) Franchise; (ii) Corporate-owned stores; and (iii) Equipment. The Company’s operations are organized and managed by type of products and services and segment information is reported accordingly. The Company’s chief operating decision maker (the “CODM”) is its interim Chief Executive Officer. The CODM reviews financial performance and allocates resources by reportable segment. There have been no operating segments aggregated to arrive at the Company’s reportable segments. The Franchise segment includes operations related to the Company’s franchising business in the United States, Puerto Rico, Canada, Panama, Mexico and Australia. The Company records all revenues and expenses of the NAF within the franchise segment. The Corporate-owned stores segment includes operations with respect to all corporate-owned stores throughout the United States and Canada. The Equipment segment includes the sale of equipment to franchisee-owned stores. The accounting policies of the reportable segments are the same as those described in Note 2. The Company evaluates the performance of its segments and allocates resources to them based on revenue and earnings before interest, taxes, depreciation, and amortization, referred to as Segment EBITDA. Revenues for all operating segments include only transactions with unaffiliated customers and include no intersegment revenues. The tables below summarize the financial information for the Company’s reportable segments.

Accounting Policies [Abstract]
Basis of presentation and consolidation	Basis of presentation and consolidation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented have been reflected. All significant intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023 are unaudited. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited financial statements at that date but does not include all of the disclosures required by GAAP. These interim condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on February 29, 2024. The Company’s significant interim accounting policies include the proportional recognition of national advertising fund expenses within interim periods. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year ending December 31, 2024.
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Although these estimates are based on management’s knowledge of current events and actions it may undertake in the future, they may ultimately differ from actual results. Significant areas where estimates and judgments are relied upon by management in the preparation of the condensed consolidated financial statements include revenue recognition, valuation of equity-based compensation awards, valuation of assets and liabilities acquired in business combinations, the evaluation of the recoverability of goodwill and long-lived assets, including intangible assets, allowance for expected credit losses, the present value of lease liabilities, income taxes, including deferred tax assets and liabilities, and the liability for the Company’s tax benefit arrangements.
Fair Value	Fair Value ASC 820, Fair Value Measurements and Disclosures , establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows: Level 1—Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2—Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
Recent accounting pronouncements	Recent accounting pronouncements The FASB issued ASU No. 2023-05, Business Combinations-Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement , in August 2023. The standard addresses the accounting for contributions made to a joint venture, upon formation, in a joint venture's separate financial statements. The new standard is effective prospectively for all joint ventures with a formation date on or after January 1, 2025. The Company will apply the standard to any relevant transactions subsequent to the adoption date. The FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosures , in November 2023. The standard expands reportable segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The new standard is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adoption on our financial disclosures. The FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures , in December 2023. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions and applies to all entities subject to income taxes. The new standard is effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of adoption on our financial disclosures.
Held-to-maturity debt security	As of March 31, 2024, the Company’s debt security investment consists of redeemable preferred shares that are accounted for as a held-to-maturity investment. The Company’s investment is measured at amortized cost within investments in the condensed consolidated balance sheets.
