Cautionary Statement Concerning Forward-Looking Statements Information in this 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, 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: changes in demand for our products and services, the seasonality and volatility of the boat industry, effects of industry wide supply chain challenges including a heightened inflationary environment and our ability to maintain adequate inventory, fluctuation in interest rates, adverse weather events, 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 a global health concern on the Company’s business, geopolitical risks, including the imposition of or changes in tariffs, duties, or other taxes affecting international trade, risks related to the ability to realize the anticipated benefits of any proposed acquisitions, including the risk that proposed 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 most recently filed Annual Report on Form 10-K, or subsequently filed Quarterly Reports on Form 10-Q, and other filings we make 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 Measures This presentation includes financial measures that are not presented in accordance with generally accepted accounting principles (“GAAP”), including Adjusted EBITDA, Adjusted Net Income Attributable to OneWater and Adjusted Diluted Earnings Per Share. While management believes Adjusted EBITDA, Adjusted Net Income Attributable to OneWater and Adjusted Diluted Earnings Per Share may be useful in performing meaningful comparisons of past and present operating results and in understanding the performance of ongoing operations and how management views the business, none are a measure of our financial performance under GAAP and none should be considered in isolation or as an alternative to any measure of such performance derived in accordance with GAAP. Adjusted EBITDA is calculated as net income (loss) before interest expense – other, income tax (benefit) expense, depreciation and amortization and other (income) expense, further adjusted to eliminate the effects of items such as the change in fair value contingent consideration, restructuring and impairment, gain (loss) on extinguishment of debt, transaction costs, and stock-based compensation. Adjusted Net Income Attributable to OneWater is calculated as net income (loss) attributable to OneWater before transaction costs, intangible amortization, change in fair value of contingent consideration, restructuring and impairment and other expense (income), all of which are then adjusted for an allocation to the non-controlling interest of OneWater Marine Holdings, LLC. Each of these adjustments are subsequently adjusted for income tax at an estimated effective tax rate. Management also reports Adjusted Diluted Earnings Per Share which presents all of the adjustments to net income attributable to OneWater noted above on a per share basis. 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 future results 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 to their corresponding GAAP measures because certain items that impact these measures are unavailable or cannot be reasonably predicted without unreasonable efforts. See the Appendix for a reconciliation to directly comparable GAAP financial measures.
