Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation, and Summary of Significant Accounting Policies	Organization, Basis of Presentation, and Summary of Significant Accounting Policies Organization Malibu Boats, Inc. (together with its subsidiaries, the “Company” or "Malibu"), a Delaware corporation formed on November 1, 2013, is the sole managing member of Malibu Boats Holdings, LLC, a Delaware limited liability company (the "LLC"). The Company operates and controls all of the LLC's business and affairs and, therefore, pursuant to Financial Accounting Standards Board ("FASB") Accounting Standards Codification (“ASC”) Topic 810, Consolidation, consolidates the financial results of the LLC and its subsidiaries, and records a non-controlling interest for the economic interest in the Company held by the non-controlling holders of units in the LLC ("LLC Units"). Malibu Boats Holdings, LLC was formed in 2006. The LLC, through its wholly owned subsidiary, Malibu Boats, LLC, (“Boats LLC”), is engaged in the design, engineering, manufacturing and marketing of innovative, high-quality, recreational powerboats that are sold through a world-wide network of independent dealers. On December 31, 2020, the Company acquired all of the outstanding stock of Maverick Boat Group, Inc. (“Maverick Boat Group”). As a result of the acquisition, the Company consolidates the financial results of the Maverick Boat Group. Maverick Boat Group designs and manufactures center console, dual console, flats and bay boats under four brands -- Cobia, Pathfinder, Maverick and Hewes brands. In addition to the Maverick Boat Group’s family of brands, the Company sells its boats under the Malibu, Axis, Cobalt and Pursuit brands. In connection with the acquisition of Maverick Boat Group, the Company revised its segment reporting to report its results of operations under three reportable segments -- Malibu, Cobalt and Saltwater Fishing. COVID-19 Pandemic The COVID-19 pandemic has impacted the Company’s operations and financial results since the third quarter of fiscal year 2020 and continues to impact the Company. The Company elected to suspend operations at all of its facilities on March 24, 2020. The shut-down continued into the fourth quarter 2020 with operations resuming between late April and early May, depending on the facility. As a result, the Company was not able to ship boats to its dealers during the period of shut-down, which negatively impacted its net sales for the second half of fiscal year 2020. In addition, the COVID-19 pandemic has impacted and may continue to impact the operations of the Company’s dealers and suppliers. The future impact of COVID-19 on the Company’s financial condition and results of operations will depend on a number of factors, including factors that we may not be able to forecast at this time. Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim condensed financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with GAAP for complete financial statements. Such statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Malibu Boats, Inc. and subsidiaries for the year ended June 30, 2020, included in the Company's Annual Report on Form 10-K. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Units and shares are presented as whole numbers while all dollar amounts are presented in thousands, unless otherwise noted. Acquisition of Maverick Boat Group, Inc. and Related Financing On December 31, 2020, MBG Holdco, Inc., a wholly-owned subsidiary of Boats, LLC, acquired all of the outstanding shares of Maverick Boat Group from its existing stockholders for a purchase price o f $150,675. T he purchase price was subject to customary adjustments for the amounts of cash, indebtedness and working capital in the business at the closing date and subject to adjustment for certain capital expenditures made by Maverick Boat Group prior to closing at the Company’s request. With two manufacturing facilities located in Fort Pierce, Florida, Maverick Boat Group designs and manufactures center console, dual console, flats and bay boats under four brand names Cobia, Pathfinder, Maverick, and Hewes. The Company paid the purchase price with cash on hand and $90,000 of borrowings under its credit facilities following an amendment to increase the amount available under its credit facilities as described below. On December 30, 2020, Boats, LLC, as the borrower, entered into the Third Incremental Facility Amendment and Third Amendment (the “Third Amendment”) to its existing Second Amended and Restated Credit Agreement dated as of June 28, 2017, by and among Boats LLC, the LLC and certain subsidiaries of Boats LLC parties thereto, as guarantors, the lenders parties thereto and Truist Bank (successor by merger to SunTrust Bank), as administrative agent, swingline lender and issuing bank (as amended, the “Credit Agreement”). The Third Amendment added a $25,000 incremental term loan facility with a maturity date of July 1, 2024 and increased the borrowing capacity available under the revolving credit facility by $50,000 from $120,000 to $170,000. The $25,000 incremental term loans made pursuant to the Third Amendment is subject to quarterly amortization at a rate of 5.0% per annum through December 31, 2022 and at a rate of 7.5% per annum thereafter and accrues interest at the same rate as other loans under the Credit Agreement. Refer to Notes 4 , 10 and 17 for further information. Segment Information Effective December 31, 2020, the Company revised its segment reporting to account for its acquisition of Maverick Boat Group and conform to changes in its internal management reporting based on the Company’s boat manufacturing operations. The Company previously had three reportable segments, Malibu, Cobalt and Pursuit. The Company now aggregates Pursuit and Maverick Boat Group into one reportable segment as they have similar economic characteristics and qualitative factors. As a result the Company continues to have three reportable segments, Malibu, Cobalt and Saltwater Fishing. See Note 17 . Principles of Consolidation The accompanying unaudited interim condensed consolidated financial statements include the operations and accounts of the Company and all subsidiaries thereof. All intercompany balances and transactions have been eliminated upon consolidation. Recent Acco unting Pronouncements In June 2016, the FASB issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , and in November 2018 issued a subsequent amendment, ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses . ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 will replace today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. ASU 2018-19 will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope of this amendment that have the contractual right to receive cash. On July 1, 2020, the Company adopted this standard and the adoption did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's consolidated financial statements and related disclosures.

Noncontrolling Interest [Abstract]
Non-controlling Interest	Non-controlling Interest The non-controlling interest on the unaudited interim condensed consolidated statement of operations and comprehensive income represents the portion of earnings attributable to the economic interest in the Company's subsidiary, Malibu Boats Holdings, LLC, held by the non-controlling LLC Unit holders. Non-controlling interest on the unaudited interim condensed consolidated balance sheets represents the portion of net assets of the Company attributable to the non-controlling LLC Unit holders, based on the portion of the LLC Units owned by such Unit holders. The ownership of Malibu Boats Holdings, LLC is summarized as follows: As of March 31, 2021 As of June 30, 2020 Units Ownership % Units Ownership % Non-controlling LLC Unit holders ownership in Malibu Boats Holdings, LLC 603,919 2.8 % 730,652 3.4 % Malibu Boats, Inc. ownership in Malibu Boats Holdings, LLC 20,844,019 97.2 20,595,969 96.6 21,447,938 100.0 % 21,326,621 100.0 % Issuance of Additional LLC Units Under the first amended and restated limited liability company agreement of the LLC, as amended (the "LLC Agreement"), the Company is required to cause the LLC to issue additional LLC Units to the Company when the Company issues additional shares of Class A Common Stock. Other than in connection with the issuance of Class A Common Stock in connection with an equity incentive program, the Company must contribute to the LLC net proceeds and property, if any, received by the Company with respect to the issuance of such additional shares of Class A Common Stock. The Company must cause the LLC to issue a number of LLC Units equal to the number of shares of Class A Common Stock issued such that, at all times, the number of LLC Units held by the Company equals the number of outstanding shares of Class A Common Stock. During the nine months ended March 31, 2021, the Company caused the LLC to issue a total of 257,715 LLC Units to the Company in connection with (i) the Company's issuance of Class A Common Stock to a non-employee director for her services, (ii) the issuance of Class A Common Stock for the vesting of awards granted under the Malibu Boats, Inc. Long-Term Incentive Plan (the "Incentive Plan"), (iii) the issuance of restricted Class A Common Stock granted under the Incentive Plan (iv) the issuance of Class A Common Stock to LLC Unit holders in exchange of their LLC Units and (v) the issuance of Class A Common Stock for the exercise of options granted under the Incentive Plan. During the nine months ended March 31, 2021, 9,665 LLC Units were canceled in connection with the vesting of share-based equity awards to satisfy employee tax withholding requirements and the retirement of 9,665 treasury shares in accordance with the LLC Agreement. Distributions and Other Payments to Non-controlling Unit Holders Distributions for Taxes As a limited liability company (treated as a partnership for income tax purposes), Malibu Boats Holdings, LLC does not incur significant federal, state or local income taxes, as these taxes are primarily the obligations of its members. As authorized by the LLC Agreement, the LLC is required to distribute cash, to the extent that the LLC has cash available, on a pro rata basis, to its members to the extent necessary to cover the members’ tax liabilities, if any, with respect to their share of LLC earnings. The LLC makes such tax distributions to its members based on an estimated tax rate and projections of taxable income. If the actual taxable income of the LLC multiplied by the estimated tax rate exceeds the tax distributions made in a calendar year, the LLC may make true-up distributions to its members, if cash or borrowings are available for such purposes. As of March 31, 2021 and June 30, 2020, tax distributions payable to non-controlling LLC Unit holders were $710 a nd $104, respectively. During the nine months ended March 31, 2021 and 2020, tax distributions paid to the non-controlling LLC Unit holders were $1,048 a nd $1,415, respectively. Other Distributions Pursuant to the LLC Agreement, the Company has the right to determine when distributions will be made to LLC members and the amount of any such distributions. If the Company authorizes a distribution, such distribution will be made to the members of the LLC (including the Company) pro rata in accordance with the percentages of their respective LLC units.

Business Combinations [Abstract]
Acquisitions	Acquisitions On December 31, 2020, the Company completed its acquisition of all the outstanding stock of Maverick Boat Group. The aggregate purchase price for the transaction was $150,675, funded with cash and borrowings under the Company's credit facilities. The aggregate purchase price was subject to certain adjustments, including customary adjustments for the amount of cash, indebtedness and working capital in the business at the closing date and subject to adjustment for certain capital expenditures made by Maverick Boat Group prior to closing at the Company’s request. The Company accounted for the transaction in accordance with ASC Topic 805, Business Combinations . The total consideration given to the stockholders of Maverick Boat Group has been allocated to the assets acquired and liabilities assumed based on preliminary estimates of fair value as of the date of the acquisition. The preliminary measurements of fair value were determined based upon estimates utilizing the assistance of third party valuation specialists, and are subject to change within the measurement period (up to one year from the acquisition date). The Company expects appraisals of tangible and intangible assets and working capital adjustments to be finalized during the fourth quarter of fiscal 2021. The following table summarizes the preliminary purchase price allocation based on the estimated fair values of the assets acquired and liabilities assumed at the acquisition date: Consideration: Cash consideration paid $ 150,675 Recognized preliminary amounts of identifiable assets acquired and (liabilities assumed), at fair value: Cash $ 248 Accounts receivable 3,204 Inventories 7,756 Other current assets 194 Property, plant and equipment 22,618 Identifiable intangible assets 102,600 Other assets 4,410 Current liabilities (6,611) Deferred tax liabilities (28,528) Other liabilities (4,405) Fair value of assets acquired and liabilities assumed 101,486 Goodwill 49,189 Total purchase price $ 150,675 The preliminary fair value estimates for the Company's identifiable intangible assets acquired as part of the acquisition are as follows: Estimates of Fair Value Estimated Useful Life (in years) Definite-lived intangibles: Dealer relationships $ 47,900 20 Total definite-lived intangibles 47,900 Indefinite-lived intangible: Trade name 54,700 Total intangible assets $ 102,600 The preliminary value allocated to inventories reflects the estimated fair value of the acquired inventory based on the expected sales price of the inventory, less an estimated cost to complete and a reasonable profit margin. The fair value of the identifiable intangible assets were determined based on the following approaches: Dealer Relationships - The value associated with Maverick Boat Group's dealer relationships is attributed to its long standing dealer distribution network. The estimate of fair value assigned to this asset was determined using the income approach, which requires an estimate or forecast of the expected future cash flows from the dealer relationships through the application of the multi-period excess earnings approach. The estimated remaining useful life of dealer relationships is approximately twenty years. Trade Name - The value attributed to Maverick Boat Group's trade names was determined using a variation of the income approach called the relief from royalty method, which requires an estimate or forecast of the expected future cash flows. The trade name has an indefinite life. The fair value of the definite-lived intangible assets are being amortized using the straight-line method to amortization expenses over their estimated useful lives. Indefinite-lived intangible assets are not amortized, but instead are evaluated for potential impairment on an annual basis in accordance with the provisions of ASC Topic 350, Intangibles—Goodwill and Other . The weighted average useful life of identifiable definite-lived intangible assets acquired was 20 years. Goodwill of $49,189 arising from the acquisition consists of expected synergies and cost savings as well as intangible assets that do not qualify for separate recognition. Acquisition-related costs of $2,602, w hich were incurred by the Company in the first nine months of fiscal year 2021 related to the Maverick Boat Group acquisition, were expensed in the period incurred, and are included in general and administrative expenses in the consolidated statement of operations and comprehensive income for the nine months ended March 31, 2021. Pro Forma Financial Information (unaudited): The following unaudited pro forma consolidated results of operations for the three and nine months ended March 31, 2021 and 2020, assumes that the acquisition of Maverick Boat Group occurred as of July 1, 2019. The unaudited interim pro forma financial information combines historical results of Malibu and Maverick Boat Group, with adjustments for depreciation and amortization attributable to preliminary fair value estimates on acquired tangible and intangible assets for the respective periods. Non-recurring pro forma adjustments associated with the fair value step up of inventory were included in the reported pro forma cost of sales and earnings. The unaudited interim pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of fiscal year 2020 or the results that may occur in the future: Three Months Ended March 31, Nine Months Ended March 31, 2021 2020 2021 2020 Net sales $ 273,162 $ 213,945 $ 705,813 $ 630,946 Net income 35,135 25,719 81,636 62,196 Net income attributable to Malibu Boats, Inc. 33,796 24,571 78,377 59,295 Basic earnings per share $ 1.62 $ 1.19 $ 3.78 $ 2.87 Diluted earnings per share $ 1.61 $ 1.18 $ 3.74 $ 2.85

Product Warranties Disclosures [Abstract]
Product Warranties	Product Warranties Malibu and Axis brand boats have a limited warranty for a period up to five years for both Malibu and Axis brand boats. The Company’s Cobalt brand boats have (1) a structural warranty of up to ten years which covers the hull, deck joints, bulkheads, floor, transom, stringers, and motor mount and (2) a five year bow-to-stern warranty on all components manufactured or purchased (excluding hull and deck structural components), including canvas and upholstery. Gelcoat is covered up to three years for Cobalt and one year for Malibu and Axis. Pursuit brand boats have (1) a limited warranty for a period of up to five years on structural components such as the hull, deck and defects in the gelcoat surface of the hull bottom and (2) a bow to stern warranty of two years (excluding hull and deck structural components). Maverick, Pathfinder and Hewes brand boats have (1) a limited warranty for a period of up to five years on structural components such as the hull, deck and defects in the gelcoat surface of the hull bottom and (2) a bow to stern warranty of one year (excluding hull and deck structural components). Cobia brand boats have (1) a limited warranty for a period of up to ten years on structural components such as the hull, deck and defects in the gelcoat surface of the hull bottom and (2) a bow to stern warranty of three years (excluding hull and deck structural components). For each boat brand, there are certain materials, components or parts of the boat that are not covered by the Company’s warranty and certain components or parts that are separately warranted by the manufacturer or supplier (such as the engine). Engines that the Company manufactures for Malibu and Axis models have a limited warranty of up to five years or five-hundred hours. The Company’s standard warranties require it or its dealers to repair or replace defective products during the warranty period at no cost to the consumer. The Company estimates warranty costs it expects to incur and records a liability for such costs at the time the product revenue is recognized. The Company utilizes historical claims trends and analytical tools to develop the estimate of its warranty obligation on a per boat basis, by brand and warranty year. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rates of warranty claims and cost per claim. The Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Beginning in model year 2016, the Company increased the term of its limited warranty for Malibu brand boats from three years to five years and for Axis brand boats from two years to five years. Beginning in model year 2018, the Company increased the term of its bow-to-stern warranty for Cobalt brand boats from three years to five years. As a result of these changes, all of the Company’s Malibu, Axis and Cobalt brand boats with historical claims experience that are no longer covered under warranty had warranty terms shorter than the current warranty term of five years. Accordingly, the Company has little to no historical claims experience for warranty years four and five, and as such, these estimates give rise to a higher level of estimation uncertainty. Future warranty claims may differ from the Company’s estimate of the warranty liability, which could lead to changes in the Company’s warranty liability in future periods. Changes in the Company’s product warranty liability, which is included in accrued expenses on the unaudited interim condensed consolidated balance sheets, were as follows: Three Months Ended March 31, Nine Months Ended March 31, 2021 2020 2021 2020 Beginning balance $ 31,046 $ 26,710 $ 27,500 $ 23,820 Add: Warranty expense 4,700 3,665 14,346 12,767 Additions for acquisitions — — 883 — Less: Warranty claims paid (3,475) (2,977) (10,458) (9,189) Ending balance $ 32,271 $ 27,398 $ 32,271 $ 27,398

As of March 31, 2021, the Company had $65,000 outstanding under its revolving credit facility and $1,234 in outstanding letters of credit, with $103,766 available for borrowing. The revolving credit facility matures on July 1, 2024, the incremental term loan made on December 30, 2020 in a principal amount of $25,000 (the “Incremental Term Loan”) matures on July 1, 2024 and the remaining $75,000 of outstanding term loans (the “Existing Term Loans,” and together with the Incremental Term Loans, the “Term Loans”) mature on July 1, 2022. On December 30, 2020, Boats LLC entered into the Third Amendment to its Credit Agreement. The Third Amendment added a $25,000 Incremental Term Loan facility with a maturity date of July 1, 2024 and increased the borrowing capacity of the revolving credit facility by $50,000 from $120,000 to $170,000. The Incremental Term Loan is subject to quarterly amortization at a rate of 5.0% per annum through December 31, 2022 and at a rate of 7.5% per annum through June 30, 2024 and accrues interest at the same interest rate applicable to other loans under the Credit Agreement as described below. The obligations of Boats LLC under the Credit Agreement are guaranteed by the LLC, and, subject to certain exceptions, the present and future domestic subsidiaries of Boats LLC, and all such obligations are secured by substantially all of the assets of the LLC, Boats LLC and such subsidiary guarantors. Malibu Boats, Inc. is not a party to the Credit Agreement. Borrowings under the Credit Agreement bear interest at a rate equal to either, at the Company's option, (i) the highest of the prime rate, the Federal Funds Rate plus 0.5%, or one-month London Inter-bank Offered Rate ("LIBOR") plus 1% (the “Base Rate”) or (ii) LIBOR, in each case plus an applicable margin ranging from 1.25% to 2.25% with respect to LIBOR borrowings and 0.25% to 1.25% with respect to Base Rate borrowings. The applicable margin will be based upon the consolidated leverage ratio of the LLC and its subsidiaries calculated on a consolidated basis. As of March 31, 2021, the interest rate on the Company’s term loans and revolving credit facility was 1.36%. The Company is required to pay a commitment fee for any unused portion of the revolving credit facility which will range from 0.20% to 0.40% per annum, depending on the LLC’s and its subsidiaries’ consolidated leverage ratio. The Credit Agreement permits prepayment of the Term Loans without any penalties. The Existing Term Loans require an amortization payment of approximately $3,000 on March 31, 2022, reflected as current maturities of long-term obligations, and the balance of the Existing Term Loans is due on the scheduled maturity date of July 1, 2022. The Incremental Term Loan of $25,000 is subject to quarterly amortization at a rate of 5.0% per year through December 31, 2022, resulting in $1,250 being reflected as current maturities of long-term obligations, 7.5% per year through June 30, 2024 and the balance of the Incremental Term Loan is due on the scheduled maturity date of July 1, 2024. The Credit Agreement also requires prepayments from the net cash proceeds received by Boats LLC or any guarantors from certain asset sales and recovery events, subject to certain reinvestment rights, and from excess cash flow, subject to the terms and conditions of the Credit Agreement. The Credit Agreement contains certain customary representations and warranties, and notice requirements for the occurrence of specific events such as the occurrence of any event of default, or pending or threatened litigation. The Credit Agreement also requires compliance with certain customary financial covenants, including a minimum ratio of EBITDA to fixed charges and a maximum ratio of total debt to EBITDA. The Credit Agreement contains certain restrictive covenants, which, among other things, place limits on certain activities of the loan parties under the Credit Agreement, such as the incurrence of additional indebtedness and additional liens on property and limit the future payment of dividends or distributions. For example, the Credit Agreement generally prohibits the LLC, Boats LLC and the subsidiary guarantors from paying dividends or making distributions, including to the Company. The credit facility permits, however, (i) distributions based on a member’s allocated taxable income, (ii) distributions to fund payments that are required under the LLC’s tax receivable agreement, (iii) purchase of stock or stock options of the LLC from former officers, directors or employees of loan parties or payments pursuant to stock option and other benefit plans up to $3,000 in any fiscal year, and (iv) share repurchase payments up to $35,000 in any fiscal year subject to one year carry forward and compliance with other financial covenants. In addition, the LLC may make dividends and distributions of up to $10,000 in any fiscal year, subject to compliance with other financial covenants. In connection with entering into the Credit Agreement, the Company capitalized $2,074 in deferred financing costs during fiscal 2017. In connection with Third Amendment the Company capitalized $638 in deferred financing costs during the nine months ended March 31, 2021. These costs, in addition to the unamortized balance related to costs associated with the Company's previous credit facility of $671, are being amortized over the term of the Credit Agreement into interest expense using the effective interest method and presented as a direct offset to the total debt outstanding on the consolidated balance sheets. The Company used proceeds from an offering on August 24, 2017 to repay $50,000 on its Existing Term Loans under the Credit Agreement and exercised its option to apply the prepayment to principal installments through December 31, 2021, and a portion of principal installments due on March 31, 2022. The $50,000 repayment resulted in a write off of deferred financing costs of $829 in fiscal year 2018, which was included in amortization expense on the consolidated statement of operations and comprehensive income. Covenant Compliance As of March 31, 2021, the Company was in compliance with the financial covenants contained in the Credit Agreement. Interest Rate Swap On July 1, 2015, the Company entered into a five year floating to fixed interest rate swap with an effective start date of July 1, 2015. The swap was based on a one-month LIBOR rate versus a 1.52% fixed rate on a notional value of $39,250, which under terms of the previously existing credit agreement, was equal to 50% of the outstanding balance of the term loan at the time of the swap arrangement. Under ASC Topic 815, Derivatives and Hedging, all derivative instruments are recorded on the unaudited interim condensed consolidated balance sheets at fair value as either short term or long term assets or liabilities based on their anticipated settlement date. The Company has elected not to designate its interest rate swap as a hedge for accounting purposes; therefore, changes in the fair value of the derivative instrument were being recognized in earnings in the Company's unaudited interim condensed consolidated statements of operations and comprehensive income. The swap matured on March 31, 2020. For the three and nine months ended March 31, 2020, the Company recorded a loss of $10 and $68, respectively, for the change in fair value of the interest rate swap, which was included in interest expense in the unaudited interim condensed consolidated statements of operations and comprehensive income.

Leases [Abstract]
Leases	LeasesThe Company leases certain manufacturing facilities, warehouses, office space, land, and equipment. The Company determines if a contract is a lease or contains an embedded lease at the inception of the agreement. The Company recorded right-of-use assets, included in other assets on the consolidated balance sheet, totaling $16,142 as of July 1, 2019. Leases with an initial term of 12 months or less are not recorded on the unaudited interim condensed consolidated balance sheet. The Company does not separate non-lease components from the lease components to which they relate, and instead accounts for each separate lease and non-lease component associated with that lease component as a single lease component for all underlying asset classes. The Company's lease liabilities do not include future lease payments related to options to extend or terminate lease agreements as it is not reasonably certain those options will be exercised. Other information concerning the Company's operating leases accounted for under ASC Topic 842, Leases is as follows: Classification As of March 31, 2021 As of June 30, 2020 Assets Right-of-use assets Other assets $ 13,111 $ 14,315 Liabilities Current operating lease liabilities Accrued expenses $ 2,034 $ 2,006 Long-term operating lease liabilities Other liabilities 12,720 14,013 Total lease liabilities $ 14,754 $ 16,019 Classification Three Months Ended March 31, 2021 Three Months Ended March 31, 2020 Nine Months Ended March 31, 2021 Nine Months Ended March 31, 2020 Operating lease costs (1) Cost of sales $ 561 $ 491 $ 1,573 $ 1,441 Selling and marketing, and general and administrative 217 211 639 654 Sublease income Other income, net 10 10 29 29 Cash paid for amounts included in the measurement of operating lease liabilities Cash flows from operating activities 661 653 1,970 1,955 (1) Includes short-term leases, which are insignificant, and are not included in the lease liability. The lease liability for operating leases that contain variable escalating rental payments with scheduled increases that are based on the lesser of a stated percentage increase or the cumulative increase in an index, are determined using the stated percentage increase. The weighted average remaining lease term for the three months ended March 31, 2021 and 2020 was 6.66 years and 7.52 years, respectively. As of March 31, 2021 and 2020, the weighted average discount rate determined based on the Company's incremental borrowing rate is 3.63% and 3.65%, respectively. Future annual minimum lease payments for the following fiscal years as of March 31, 2021 are as follows: Amount Remainder of 2021 $ 645 2022 2,508 2023 2,519 2024 2,603 2025 2,313 2026 and thereafter 6,014 Total 16,602 Less imputed interest (1,848) Present value of lease liabilities $ 14,754

Tax Receivable Agreement Liabil

Tax Receivable Agreement Liability	9 Months Ended

Tax Receivable Agreement [Abstract]
Tax Receivable Agreement Liability	Tax Receivable Agreement LiabilityThe Company has a tax receivable agreement with the pre-IPO owners of the LLC that provides for payment by the Company to the pre-IPO owners (or their permitted assignees) of 85% of the amount of the benefits, if any, that the Company is deemed to realize as a result of (i) increases in tax basis and (ii) certain other tax benefits related to the Company entering into the tax receivable agreement, including those attributable to payments under the tax receivable agreement. These contractual payment obligations are obligations of the Company and not of the LLC. The Company's tax receivable agreement liability was determined on an undiscounted basis in accordance with ASC Topic 450, Contingencies , since the contractual payment obligations were deemed to be probable and reasonably estimable. The tax receivable agreement further provides that, upon certain mergers, asset sales or other forms of business combinations or other changes of control, the Company (or its successor) would owe to the pre-IPO owners of the LLC a lump-sum payment equal to the present value of all forecasted future payments that would have otherwise been made under the tax receivable agreement that would be based on certain assumptions, including a deemed exchange of LLC Units and that the Company would have sufficient taxable income to fully utilize the deductions arising from the increased tax basis and other tax benefits related to entering into the tax receivable agreement. The Company also is entitled to terminate the tax receivable agreement, which, if terminated, would obligate the Company to make early termination payments to the pre-IPO owners of the LLC. In addition, a pre-IPO owner may elect to unilaterally terminate the tax receivable agreement with respect to such pre-IPO owner, which would obligate the Company to pay to such existing owner certain payments for tax benefits received through the taxable year of the election. For purposes of the tax receivable agreement, the benefit deemed realized by the Company will be computed by comparing the actual income tax liability of the Company (calculated with certain assumptions) to the amount of such taxes that the Company would have been required to pay had there been no increase to the tax basis of the assets of the LLC as a result of the purchases or exchanges, and had the Company not entered into the tax receivable agreement. The following table reflects the changes to the Company's tax receivable agreement liability: As of March 31, 2021 As of June 30, 2020 Payable pursuant to tax receivable agreement $ 49,665 $ 53,754 Additions (reductions) to tax receivable agreement: Exchange of LLC Units for Class A Common Stock 2,074 1,041 Adjustment for change in estimated tax rate — (1,672) Payments under tax receivable agreement — (3,458) 51,739 49,665 Less current portion under tax receivable agreement (3,589) (3,589) Payable pursuant to tax receivable agreement, less current portion $ 48,150 $ 46,076 When estimating the expected tax rate to use in order to determine the tax benefit expected to be recognized from the Company’s increased tax basis as a result of exchanges of LLC Units by the pre-IPO owners of the LLC, the Company continuously monitors changes in its overall tax posture, including changes resulting from new legislation and changes as a result of new jurisdictions in which the Company is subject to tax.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Malibu Boats, Inc. is taxed as a C corporation for U.S. income tax purposes and is therefore subject to both federal and state taxation at a corporate level. The LLC continues to operate in the United States as a partnership for U.S. federal income tax purposes. Income taxes are computed in accordance with ASC Topic 740, Income Taxes , and reflect the net tax effects of temporary differences between the financial reporting carrying amounts of assets and liabilities and the corresponding income tax amounts. The Company has deferred tax assets and liabilities and maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. To the extent the Company determines that it will not realize the benefit of some or all of its deferred tax assets, such deferred tax assets will be adjusted through the Company’s provision for income taxes in the period in which this determination is made. As of March 31, 2021 and June 30, 2020, the Company maintained a total valuation allowance of $15,006 and $14,582, respectively, against deferred tax assets related to state net operating losses and future amortization deductions (with respect to the Section 754 election) that are reported in the Tennessee corporate tax return without offsetting income, which is taxable at the LLC. This also includes a valuation allowance in the amount of $580 related to foreign tax credit carryforward that is not expected to be utilized in the future. The Company’s consolidated interim effective tax rate is based upon expected annual income from operations, statutory tax rates and tax laws in the various jurisdictions in which the Company operates. Significant or unusual items, including those related to the change in U.S. tax law as well as other adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event occurs. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was signed into law. The CARES Act contains significant business tax provisions, including modifications to the rules limiting the deductibility of net operating losses (NOLs), expensing of qualified improvement property (QIP) and business interest in Internal Revenue Code Sections 172(a) and 163(j), respectively. The effects of the new legislation are recognized upon enactment. The Company did not recognize any significant impact to income tax expense for the nine months ended March 31, 2021 relating to the CARES Act. For the three months ended March 31, 2021 and 2020, the Company's effective tax rate was 23.7% and 22.6%, respectively. For the nine months ended March 31, 2021 and 2020, the Company's effective tax rate was 23.0% and 22.5%, respectively. For the three and nine months ended March 31, 2021 and 2020, the Company's effective tax rate exceeded the statutory federal income tax rate of 21% primarily due to the impact of U.S. state taxes. This increase in tax rate in both periods was partially offset by a windfall benefit generated by certain stock based compensation, and benefits from the foreign derived intangible income deduction, the research and development tax credit, and the impact of non-controlling interests in the LLC.

Stock-Based Compensation

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company adopted a long term incentive plan which became effective on January 1, 2014, and reserves for issuance up to 1,700,000 shares of Malibu Boats, Inc. Class A Common Stock for the Company’s employees, consultants, members of its board of directors and other independent contractors at the discretion of the compensation committee. Incentive stock awards authorized under the Incentive Plan include unrestricted shares of Class A Common Stock, stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent awards and performance awards. As of March 31, 2021, 596,372 shares remain available for future issuance under the long term incentive plan. On November 3, 2020, under the Incentive Plan, the Company granted approximately 33,000 restricted service based stock units and 25,000 restricted service based stock awards to key employees under the Incentive Plan. The grant date fair value of these awards was $3,145 based on a stock price of $54.47 per share on the date of grant. Approximately 58% of the awards vest ratably over three years and approximately 42% of the awards vest ratably over four years. Stock-based compensation expense attributable to the service based units and awards is amortized on a straight-line basis over the requisite service period. On November 3, 2020, under the Incentive Plan, the Company granted to key employees a target amount of approximately 18,000 restricted stock awards with a performance condition. The number of shares that will ultimately be issued, if any, is based on the attainment of a specified amount of earnings during the fiscal year ending June 30, 2023. The maximum number of shares that can be issued if an elevated earnings target is met is approximately 28,000. The grant date fair value of the awards were estimated to be $1,002, based on a stock price of $54.47. Compensation costs associated with the performance awards are recognized over the requisite service period based on probability of achievement in accordance with ASC Topic 718 , Compensation—Stock Compensation. On November 3, 2020, under the Incentive Plan, the Company granted to key employees a target amount of approximately 18,000 stock awards with a market condition. The number of shares that will ultimately be issued, if any, is based on a total shareholder return ("TSR") computation that involves comparing the movement in the Company's stock price to movement in a market index from the grant date through November 6, 2023. The maximum number of shares that can be issued if an elevated TSR target is met is approximately 37,000. The grant date fair value of the awards were estimated to be $1,293, which is estimated using a Monte Carlo simulation. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair market value for the stock award. Compensation costs are recognized over the requisite service period based on probability of achievement in accordance with ASC Topic 718 , Compensation—Stock Compensation. The following is a summary of the changes in the Company's stock options for the nine months ended March 31, 2021: Shares Weighted Average Exercise Price/Share Total outstanding options as of June 30, 2020 173,348 $ 32.61 Options granted — — Options exercised (11,625) 32.24 Outstanding options as of March 31, 2021 161,723 32.64 Exercisable as of March 31, 2021 85,737 $ 31.67 The following is a summary of the changes in non-vested restricted stock units and restricted stock awards for the nine months ended March 31, 2021: Number of Restricted Stock Units and Restricted Stock Awards Outstanding Weighted Average Grant Date Fair Value Total Non-vested Restricted Stock Units and Restricted Stock Awards as of June 30, 2020 277,696 $ 35.43 Granted 140,916 54.83 Vested (92,766) 32.51 Forfeited (4,237) 41.51 Total Non-vested Restricted Stock Units and Restricted Stock Awards as of March 31, 2021 321,609 $ 44.69

Net Earnings Per Share

Net Earnings Per Share	9 Months Ended

Earnings Per Share [Abstract]
Net Earnings Per Share	Net Earnings Per Share Basic net income per share of Class A Common Stock is computed by dividing net income attributable to the Company's earnings by the weighted average number of shares of Class A Common Stock outstanding during the period. The weighted average number of shares of Class A Common Stock outstanding used in computing basic net income per share includes fully vested restricted stock units awarded to directors that are entitled to participate in distributions to common shareholders through receipt of additional units of equivalent value to the dividends paid to Class A Common Stock holders. Diluted net income per share of Class A Common Stock is computed similarly to basic net income per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents using the treasury method, if dilutive. The LLC Units and non-qualified stock options are considered common stock equivalents for this purpose. The number of additional shares of Class A Common Stock related to these common stock equivalents and stock options are calculated using the treasury stock method. Stock awards with a performance condition that are based on the attainment of a specified amount of earnings are only included in the computation of diluted earnings per share to the extent that the performance condition would be achieved based on the current amount of earnings, and only if the effect would be dilutive. Stock awards with a market condition that are based on the performance of the Company's stock price in relation to a market index over a specified time period are only included in the computation of diluted earnings per share to the extent that the shares would be issued based on the current market price of the Company's stock in relation to the market index, and only if the effect would be dilutive. Basic and diluted net income per share of Class A Common Stock has been computed as follows (in thousands, except share and per share amounts): Three Months Ended March 31, Nine Months Ended March 31, 2021 2020 2021 2020 Basic: Net income attributable to Malibu Boats, Inc. $ 33,796 $ 22,778 $ 76,114 $ 55,359 Shares used in computing basic net income per share: Weighted-average Class A Common Stock 20,571,601 20,417,829 20,499,949 20,479,874 Weighted-average participating restricted stock units convertible into Class A Common Stock 227,804 212,912 222,390 204,160 Basic weighted-average shares outstanding 20,799,405 20,630,741 20,722,339 20,684,034 Basic net income per share $ 1.62 $ 1.11 $ 3.67 $ 2.68 Diluted: Net income attributable to Malibu Boats, Inc. $ 33,796 $ 22,778 $ 76,114 $ 55,359 Shares used in computing diluted net income per share: Basic weighted-average shares outstanding 20,799,405 20,630,741 20,722,339 20,684,034 Restricted stock units granted to employees 97,376 105,096 90,592 109,225 Stock options granted to employees 69,613 13,535 61,030 8,963 Market performance awards granted to employees 65,966 25,736 65,966 25,736 Diluted weighted-average shares outstanding 1 21,032,360 20,775,108 20,939,927 20,827,958 Diluted net income per share $ 1.61 $ 1.09 $ 3.63 $ 2.66 1 The Company excluded (i) 603,919 and 889,500 potentially dilutive shares from the calculation of diluted net income per share for the three months ended March 31, 2021 and 2020, respectively, and (ii) 622,306 and 890,750 potentially dilutive shares from the calculation of diluted net income per share for the nine months ended March 31, 2021 and 2020, respectively, as these units would have been antidilutive. The shares of Class B Common Stock do not share in the earnings or losses of Malibu Boats, Inc. and, therefore, are not included in the calculation. Accordingly, basic and diluted net earnings per share of Class B Common Stock has not been presented.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Repurchase Commitments In connection with its dealers’ wholesale floor plan financing of boats, the Company has entered into repurchase agreements with various lending institutions. The reserve methodology used to record an estimated expense and loss reserve in each accounting period is based upon an analysis of likely repurchases based on current field inventory and likelihood of repurchase. Subsequent to the inception of the repurchase commitment, the Company evaluates the likelihood of repurchase and adjusts the estimated loss reserve accordingly. When a potential loss reserve is recorded it is presented in accrued liabilities in the accompanying unaudited interim condensed consolidated balance sheet. If the Company were obligated to repurchase a significant number of units under any repurchase agreement, its business, operating results and financial condition could be adversely affected. The total amount financed under the floor financing programs with repurchase obligations was $201,137 and $161,356 as of March 31, 2021 and June 30, 2020, respectively. Repurchases and subsequent sales are recorded as a revenue transaction. The net difference between the repurchase price and the resale price is recorded against the loss reserve and presented in cost of sales in the accompanying unaudited interim condensed consolidated statements of operations and comprehensive income. During the three and nine months ended March 31, 2021, there were no repurchases and as of March 31, 2021, the Company has not been notified about any probable repossessions. Therefore, the Company did not carry a reserve for repurchases as of March 31, 2021 consistent with June 30, 2020. The Company has collateralized receivables financing arrangements with a third-party floor plan financing provider for European dealers. Under terms of these arrangements, the Company transfers the right to collect a trade receivable to the financing provider in exchange for cash but agrees to repurchase the receivable if the dealer defaults. Since the transfer of the receivable to the financing provider does not meet the conditions for a sale under ASC Topic 860 , Transfers and Servicing , the Company continues to report the transferred trade receivable in other current assets with an offsetting balance recorded as a secured obligation in accrued expenses in the Company's unaudited condensed consolidated balance sheets. As of March 31, 2021 and June 30, 2020, the Company had financing receivables of $73 and $375, respectively, recorded in other current assets and accrued expenses related to these arrangements. Contingencies Product Liability The Company is engaged in a business that exposes it to claims for product liability and warranty claims in the event the Company’s products actually or allegedly fail to perform as expected or the use of the Company’s products results, or is alleged to result, in property damage, personal injury or death. Although the Company maintains product and general liability insurance of the types and in the amounts that the Company believes are customary for the industry, the Company is not fully insured against all such potential claims. The Company may have the ability to refer claims to its suppliers and their insurers to pay the costs associated with any claims arising from the suppliers’ products. The Company’s insurance covers such claims that are not adequately covered by a supplier’s insurance and provides for excess secondary coverage above the limits provided by the Company’s suppliers. The Company may experience legal claims in excess of its insurance coverage or claims that are not covered by insurance, either of which could adversely affect its business, financial condition and results of operations. Adverse determination of material product liability and warranty claims made against the Company could have a material adverse effect on its financial condition and harm its reputation. In addition, if any of the Company's products are, or are alleged to be, defective, the Company may be required to participate in a recall of that product if the defect or alleged defect relates to safety. These and other claims that the Company faces could be costly to the Company and require substantial management attention. Refer to Note 9 for discussion of warranty claims. The Company insures against product liability claims and believes there are no material product liability claims as of March 31, 2021 that would not be covered by our insurance. Legal Proceedings On January 12, 2018, the Company filed suit against Skier’s Choice, Inc., or "Skier’s Choice," in the U.S. District Court for the Eastern District of Tennessee, seeking monetary and injunctive relief. The Company's complaint alleges Skier’s Choice’s infringement of three utility patents - U.S. Patent Nos. 9,260,161, 8,578,873, and 9,199,695 - related to wake surfing technology. Skier’s Choice denied liability arising from the causes of action alleged in the Company's complaint and filed counterclaims alleging invalidity of the asserted patents. On June 19, 2019, the Company filed a second action against Skier’s Choice in the U.S. District Court for the Eastern District of Tennessee, seeking monetary and injunctive relief. The Company’s complaint alleges Skier’s Choice’s surf systems on its Moomba and Supra lines of boats infringe U.S. Patent No. 10,322,777, a patent related to wake surfing technology. Skier’s Choice denied liability arising from the causes of action alleged in the Company's complaint and filed counterclaims alleging invalidity of the asserted patents. On June 27, 2019, Skier’s Choice filed a motion to consolidate these two actions, and to continue deadlines in the earlier case for nine months, which the Company opposed. On August 22, 2019, the motion for consolidation was referred by Judge Thomas Varlan to Magistrate Judge Bruce Guyton, and the two cases were stayed pending resolution of that motion. On November 27, 2019, Judge Guyton ordered the two cases to be consolidated. On January 7, 2020, the consolidated cases were reassigned to Judge Jon McCalla. On January 23, 2020, Judge McCalla issued a Scheduling Order, scheduling trial on the consolidated cases to begin on September 29, 2020. On July 23, 2020, the Company moved to dismiss its allegations of infringement of U.S. Patent No. 9,199,695, which Skier’s Choice opposed. On August 25, 2020, Judge McCalla issued a claim construction order and set a scheduling conference for August 27, 2020, for purposes of resetting the pretrial calendar and trial dates. On September 11, 2020, the Court issued a

Segment Information	Segment Information Effective December 31, 2020, the Company revised its segment reporting to account for its acquisition of Maverick Boat Group and conform to changes in its internal management reporting based on the Company’s boat manufacturing operations. The Company previously had three reportable segments, Malibu, Cobalt and Pursuit. The Company now aggregates Pursuit and Maverick Boat Group into one reportable segment as they have similar economic characteristics and qualitative factors. As a result, the Company continues to have three reportable segments, Malibu, Cobalt and Saltwater Fishing. The Malibu segment participates in the manufacturing, distribution, marketing and sale of Malibu and Axis performance sports boats throughout the world. The Cobalt segment participates in the manufacturing, distribution, marketing and sale of Cobalt boats throughout the world. The Saltwater Fishing segment participates in the manufacturing, distribution, marketing and sale throughout the world of Pursuit boats and the Maverick Boat Group brand boats (Maverick, Cobia, Pathfinder and Hewes). There is no country outside of the United States from which we (a) derived net sales equal to 10% of total net sales, or (b) attributed assets equal to 10% of total assets.

ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 will replace today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. ASU 2018-19 will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope of this amendment that have the contractual right to receive cash. On July 1, 2020, the Company adopted this standard and the adoption did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's consolidated financial statements and related disclosures.
