Comparison of the Third Quarter Ended March 31, 2019 to the Third Quarter Ended March 31, 2018

Net sales for the three months ended March 31, 2019 increased $59.5 million, or 42.4%, to $199.9 million as compared to the three months ended March 31, 2018. Unit volume for the three months ended March 31, 2019, increased 308 units, or 17.2%, to 2,094 units as compared to the three months ended March 31, 2018.

Net sales attributable to our Malibu U.S. segment increased $15.9 million, or 18.6%, to $101.6 million for the three months ended March 31, 2019, compared to the three months ended March 31, 2018. Unit volumes attributable to our Malibu U.S. segment increased 124 units for the three months ended March 31, 2019, compared to the three months ended March 31, 2018. The increase in net sales and unit volume for Malibu U.S. was driven primarily by strong demand for new models and optional features, which led to a higher net sales per unit for Malibu and Axis models. Net sales was also impacted by year-over-year price increases on all of our Malibu and Axis models.

Net sales from our Cobalt segment increased $6.1 million, or 12.3%, to $56.0 million for the three months ended March 31, 2019, compared to the three months ended March 31, 2018. Unit volumes attributable to Cobalt increased 30 units for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. The increase in Cobalt net sales and unit volume was driven primarily by strong demand for our R series models. Net sales was also impacted by year-over-year price increases on all of our Cobalt models.

Since our acquisition of Pursuit on October 15, 2018, net sales and unit volume contributed by Pursuit were $36.5 million and 143 units, respectively, for the three months ended March 31, 2019.

Net sales from our Malibu Australia segment increased $1.0 million, or 20.6%, to $5.8 million for the three months ended March 31, 2019, compared to the three months ended March 31, 2018.

Exhibit 99.1

Overall consolidated net sales per unit increased 21.4% to $95,472 for the three months ended March 31, 2019, compared to the three months ended March 31, 2018. Net sales per unit for our Malibu U.S. segment increased 6.7% to $82,401 for the three months ended March 31, 2019, compared to the three months ended March 31, 2018, driven by strong demand for new models and optional features and year-over-year price increases. Net sales per unit for our Cobalt segment increased 7.0% to $86,885 for the three months ended March 31, 2019, compared to the three months ended March 31, 2018, driven by a favorable mix of R series models which have a higher average selling price as well as year-over-year price increases. Net sales per unit for Pursuit for the three months ended March 31, 2019 was $254,951.

Cost of sales for the three months ended March 31, 2019 increased $46.1 million, or 44.3%, to $150.2 million as compared to the three months ended March 31, 2018. The increase in cost of sales was driven primarily by incremental costs contributed by Pursuit since its acquisition in October 2018 and an increase in unit volumes at our Malibu U.S. and Cobalt businesses.

Gross profit for the three months ended March 31, 2019 increased $13.4 million, or 36.7%, to $49.7 million compared to the three months ended March 31, 2018. The increase in gross profit was due mainly to higher unit volumes. Gross margin for the three months ended March 31, 2019 decreased 100 basis points from 25.9% to 24.9% over the same period in the prior fiscal year primarily due to the integration of Pursuit. Our gross margins increased year-over-year for our comparable businesses primarily as a result of our operational efficiency initiatives.

Selling and marketing expenses for the three month period ended March 31, 2019, increased $2.0 million or 61.6% compared to the three months ended March 31, 2018 due primarily to the incremental expenses incurred as a result of the acquisition of Pursuit. As a percentage of sales, selling and marketing expenses increased 30 basis points compared to the same period in the prior fiscal year. General and administrative expenses for the three months ended March 31, 2019, increased $4.5 million, or 56.8%, to $12.3 million as compared to the three months ended March 31, 2018, largely due to incremental general and administrative expenses attributable to Pursuit, integration related expenses for our acquisition of Pursuit and higher legal expenses related to intellectual property litigation. As a percentage of sales, general and administrative expenses increased 60 basis points to 6.2% for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. Amortization expense for the three month period ended March 31, 2019, increased $0.3 million, or 21.1% to $1.6 million compared to the three months ended March 31, 2018 due to additional amortization expense related to intangibles acquired as part of the Pursuit acquisition.

Operating income for the third quarter of fiscal year 2019 increased to $30.6 million from $23.9 million in the third quarter of fiscal year 2018. Net income for the third quarter of fiscal year 2019 increased 32.2% to net income of $22.2 million from $16.8 million and net income margin decreased to 11.1% from 12.0% in the third quarter of fiscal year 2018. Adjusted EBITDA in the third quarter of fiscal year 2019 increased 32.4% to $37.8 million from $28.5 million, while Adjusted EBITDA margin decreased to 18.9% from 20.3% in the third quarter of fiscal year 2018.

Forward Looking Statements

This press release includes forward-looking statements (as such term is defined in the Private Securities Litigation Reform Act of 1995). Forward-looking statements can be identified by such words and phrases as “believes,” “anticipates,” “expects,” “intends,” “estimates,” “may,” “will,” “should,” “continue” and similar expressions, comparable terminology or the negative thereof, and includes the statements in this press release regarding our confidence in the current and summer selling seasons, our expectation to bring our Malibu Monsoon engines to 100% of our Malibu and Axis boats by fiscal year 2020, our optimism about the U.S. marine market and our belief that we are well-positioned to drive strong sales growth, expand profitability and deliver increased value to our shareholders.

Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the forward-looking statements, including, but not limited to: the impact of our recent acquisition of the assets of Pursuit; our ability to grow our business through acquisitions or strategic alliances and new partnerships; general industry, economic and business conditions; demand for our products; changes in consumer preferences; competition within our industry; our reliance on our network of independent dealers; our ability to manage our manufacturing levels and our large fixed cost base; the successful introduction of our new products; the success of our engines integration strategy; and other factors affecting us detailed from time to time in our filings with the Securities and Exchange Commission. Many of these risks and uncertainties are outside our control, and there may be other risks and uncertainties which we do not currently anticipate because they relate to events and depend on circumstances that may or may not occur in the future. Although we believe that the expectations reflected in any forward-looking statements are based on reasonable assumptions at the time made, we can give no assurance that our expectations will be achieved. Undue reliance should not be placed on these forward-looking statements, which speak only as of the date hereof. We undertake no obligation (and we expressly disclaim any obligation) to update or supplement any forward-looking statements that may become untrue because of subsequent events, whether because of new information, future events, changes in assumptions or otherwise. Comparison of results for current and prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

Use and Definition of Non-GAAP Financial Measures

This release includes the following financial measures defined as non-GAAP financial measures by the SEC: Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Fully Distributed Net Income and Adjusted Fully Distributed Net Income per Share. These measures have limitations as analytical tools and should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of our liquidity. Our presentation of these non-GAAP financial measures should also not be construed as an inference that our results will be unaffected by unusual or non-recurring items. Our computations of these non-GAAP financial measures may not be comparable to other similarly titled measures of other companies.

We define Adjusted EBITDA as net income before interest expense, income taxes, depreciation, amortization and non-cash, non-recurring or non-operating expenses, including certain professional fees, acquisition and integration related expenses, non-cash compensation expense, expenses related to our engine development initiative and adjustments to our tax receivable agreement liability. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by net sales. Adjusted EBITDA and Adjusted EBITDA Margin are not measures of net income as determined by GAAP. Management believes Adjusted EBITDA and Adjusted EBITDA Margin allow investors to evaluate our operating performance and compare our results of operations from period to period on a consistent basis by excluding items that management does not believe are indicative of core operating performance. Management uses Adjusted EBITDA to assist in highlighting trends in our operating results without regard to our financing methods, capital structures, and non-recurring or non-operating expenses. We exclude the items listed above from net income in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital

Exhibit 99.1

structures, the methods by which assets were acquired and other factors.

Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historical costs of depreciable assets.

We define Adjusted Fully Distributed Net Income as net income attributable to Malibu Boats, Inc. (i) excluding income tax expense, (ii) excluding the effect of non-recurring or non-cash items, (iii) assuming the exchange of all LLC units into shares of Class A Common Stock, which results in the elimination of non-controlling interest in Malibu Boats Holdings, LLC (the "LLC"), and (iv) reflecting an adjustment for income tax expense on fully distributed net income before income taxes at our estimated effective income tax rate. Adjusted Fully Distributed Net Income is a non-GAAP financial measure because it represents net income attributable to Malibu Boats, Inc., before non-recurring or non-cash items and the effects of non-controlling interests in the LLC. We use Adjusted Fully Distributed Net Income to facilitate a comparison of our operating performance on a consistent basis from period to period that, when viewed in combination with our results prepared in accordance with GAAP, provides a more complete understanding of factors and trends affecting our business than GAAP measures alone. We believe Adjusted Fully Distributed Net Income assists our board of directors, management and investors in comparing our net income on a consistent basis from period to period because it removes non-cash or non-recurring items, and eliminates the variability of non-controlling interest as a result of member owner exchanges of LLC units into shares of Class A Common Stock. In addition, because Adjusted Fully Distributed Net Income is susceptible to varying calculations, the Adjusted Fully Distributed Net Income measures, as presented in this release, may differ from and may, therefore, not be comparable to similarly titled measures used by other companies.

A reconciliation of our net income as determined in accordance with GAAP to Adjusted EBITDA and Adjusted EBITDA Margin, and of our net income attributable to Malibu Boats, Inc. to Adjusted Fully Distributed Net Income is provided under "Reconciliation of Non-GAAP Financial Measures".

(2)	For the three and nine months ended March 31, 2019, represents legal and advisory fees related to our litigation with Skier's Choice, Inc. For the nine months ended March 31, 2018, represents legal and advisory fees related to our litigation with MasterCraft Boat Company, LLC ("MasterCraft") which was settled in May 2017.

For the nine months ended March 31, 2018, we recognized other income as a result of a decrease in our estimated tax receivable agreement liability. The reduction in our tax receivable agreement liability resulted from the adoption of the Tax Act, which decreased the estimated tax rate used in computing our future tax obligations and, in turn, decreased the future tax benefit we expect to pay under our tax receivable agreement with pre-IPO owners.

Exhibit 99.1



(1)	Provision for income taxes for the nine months ended March 31, 2018 reflects an increase to income tax expense of $47.2 million for the remeasurement of deferred taxes on the enactment date of the Tax Act adopted in December 2017 and deferred tax impact related to the reduction in the tax receivable agreement liability.

For the three and nine months ended March 31, 2018 represents integration costs and legal and advisory fees incurred in connection with our acquisition of Cobalt on July 6, 2017. Integration related expenses for the nine months ended March 31, 2019 include post-acquisition adjustments to cost of goods sold of $0.9 million for the fair value step up of inventory acquired, most of which was sold during the second quarter of fiscal 2019. In addition, for the three and nine months ended March 31, 2019, integration related expenses includes $0.4 million and $0.8 million, respectively, in depreciation and amortization associated with our fair value step up of property, plant and equipment and intangibles acquired in connection with the acquisition of Pursuit.

(5)	Represents equity-based incentives awarded to certain of our employees under the Malibu Boats, Inc. Long-Term Incentive Plan and profit interests issued under the previously existing limited liability company agreement of the LLC.
(6)	Represents costs incurred in connection with our vertical integration of engines including product development costs and supplier transition performance incentives.
(7)	For the three and nine months ended March 31, 2019 we recognized other income from an adjustment in our tax receivable agreement liability as a result of a decrease in the estimated tax rate used in computing our future tax obligations and in turn, a decrease in the future tax benefit we expect to pay under our tax receivable agreement with pre-IPO owners. For the nine months ended March 31, 2018, we recognized other income as a result of a decrease in our estimated tax receivable agreement liability. The reduction in our tax receivable agreement liability resulted from the adoption of the Tax Act, which decreased the estimated tax rate used in computing our future tax obligations and, in turn, decreased the future tax benefit we expect to pay under our tax receivable agreement with pre-IPO owners.
(8)	Reflects the elimination of the non-controlling interest in the LLC as if all LLC members had fully exchanged their LLC Units for shares of Class A Common Stock.
(9)	Reflects income tax expense at an estimated normalized annual effective income tax rate of 24.1% for the three and nine months ended March 31, 2019, 23.2% for the three months ended March 31, 2018, and 28.7% for the nine months ended March 31, 2018, in each case, assuming the conversion of all LLC Units into shares of Class A Common Stock. The estimated normalized annual effective income tax rate for the three and nine months ended March 31, 2019 is based on the federal statutory rate plus a blended state rate adjusted for the research and development tax credit and foreign income taxes attributable to our Australian based subsidiary. The estimated normalized effective tax rate for the three months ended March 31, 2018 is based on the federal statutory rate plus a blended state rate adjusted for deductions under Section 199 of the Internal Revenue Code , state taxes attributable to the LLC, and foreign income taxes attributable to our Australian based subsidiary.

The increase in the normalized annual effective income tax rate to 24.1% for the three months ended March 31, 2019 compared to 23.2% for the three months ended March 31, 2018 is primarily the result of estimated effective state taxes as a result of our anticipated state filings following our acquisitions. The decrease in the rate for the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018 is primarily the result of the Tax Act which was effective for periods after January 1, 2018, lowering the corporate tax rate to 21%, as well as an updated blended state rate, which considers the impacts of the Cobalt acquisition and a recent law change in Tennessee.
(10)	The difference in weighted average shares outstanding for the three and nine months ended March 31, 2018 relates to the difference in the weighting of shares outstanding of Class A common stock during this period for the calculation of basic net income per share for our financial statements and basic net income per share for adjusted fully distributed net income.
(11)	Represents the weighted average shares outstanding of LLC Units held by non-controlling interests assuming they were exchanged into Class A Common Stock on a one-for-one basis.
(12)	Represents the weighted average unvested restricted stock awards included in outstanding shares during the applicable period that were convertible into Class A Common Stock and granted to members of management.
