presentation of OneWater Marine Inc. (“OneWater,” “ONEW,” the “Company,” “we,” or “us”), and any oral statements made in connection therewith, may contain “forward-looking statements” within the meaning of the Private Securities Litigation
Reform Act of 1995, including regarding our strategy, our expectations with respect to the acquisition, future operations, financial position, prospects, plans and objectives of management, growth rate and its expectations regarding future
revenue, operating income or loss or earnings or loss per share. In some cases, you can identify forward-looking statements because they contain words such as “may,” “will,” “will be,” “will likely result,” “should,” “expects,” “plans,”
“anticipates,” “could,” “would,” “foresees,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential,” “outlook” or “continue” or the negative of these words or other similar terms or expressions that
concern our expectations, strategy, plans or intentions. These forward-looking statements are not guarantees of future performance, but are based on management’s current expectations, assumptions and beliefs concerning future developments and
their potential effect on us, which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict. Our expectations expressed or implied in these forward-looking statements may not turn out to be
correct.Important factors, some of which are beyond our control, that could cause actual results to differ materially from our historical results or those expressed or implied by these forward-looking statements include the following: risks
related to the satisfaction of the conditions to closing the acquisition in the anticipated timeframe or at all, including the financing condition, risks related to the ability to realize the anticipated benefits of the acquisition, including
the possibility that the expected benefits from the proposed acquisition will not be realized or will not be realized within the expected time period, the risk that the businesses will not be integrated successfully, effects of industry wide
supply chain challenges and our ability to maintain adequate inventory, changes in demand for our products and services, the seasonality and volatility of the boat industry, our acquisition and business strategies, the inability to comply with
the financial and other covenants and metrics in our credit facilities, cash flow and access to capital, effects of the COVID-19 pandemic and related governmental actions or restrictions on the Company’s business, risks related to the ability
to realize the anticipated benefits of any proposed or recent acquisitions within the anticipated timeframe or at all, including the risk that proposed or recent acquisitions will not be integrated successfully, the timing of development
expenditures, and other risks. More information on these risks and other potential factors that could affect our financial results is included in our filings with the Securities and Exchange Commission, including in the “Risk Factors” and
“Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020 and in our subsequently filed Quarterly Reports on Form 10-Q, each
of which is on file with the SEC and available from OneWater Marine’s website at www.onewatermarine.com under the “Investors” tab, and in other documents OneWater Marine files with the SEC. Any forward-looking statement speaks only as of the
date as of which such statement is made, and, except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether because of new information, future events, or otherwise.Non-GAAP Financial
MeasuresThis presentation includes financial measures that are not presented in accordance with generally accepted accounting principles (“GAAP”), including Adjusted EBITDA. While management believes Adjusted EBITDA may be useful in performing
meaningful comparisons of past and present operating results, to understand the performance of its ongoing operations and how management views the business, it is not a measure of our financial performance under GAAP and should not be
considered in isolation or as an alternative to any measure of such performance derived in accordance with GAAP. Adjusted net income before interest expense – other, income tax expense, depreciation and amortization and other (income) expense,
further adjusted to eliminate the effects of items such as the change in fair value of warrant liability, loss on contingent consideration, loss on extinguishment of debt and transaction costs. Amounts excluded from these non-GAAP measures in
future periods could be significant and our current presentation of these non-GAAP measures should not be construed as an inference that our futureresults will be unaffected by unusual or non-recurring items. These non-GAAP measures have
limitations as analytical tools and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. Because our non-GAAP financial measures may be defined differently by other companies, our
definition of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing its utility. We have not reconciled non‐GAAP forward-looking measures, including Adjusted EBITDA
guidance, to their corresponding GAAP measures due to the high variability and difficulty in making accurate forecasts and projections, particularly with respect to acquisition contingent consideration and transaction costs. Acquisition
contingent consideration and transaction costs are affected by the acquisition, integration and post-acquisition performance of our acquirees which is difficult to predict and subject to change. Accordingly, reconciliations of forward-looking
Adjusted EBITDA is not available without unreasonable effort. IIndustry and Market DataThis presentation includes market data and other statistical information from third-party sources, including independent industry publications or other
