Accordingly, these Unaudited Condensed Consolidated Financial Statements do not include all of the information and note disclosures required by accounting principles generally accepted in the United States for complete financial statements. All adjustments, consisting of only normal recurring adjustments considered necessary for fair presentation, have been reflected in these Unaudited Condensed Consolidated Financial Statements. The operating results for the nine months ended June 30, 2025, are not necessarily indicative of the results that may be expected in future periods.

Significant estimates made by us in the accompanying Unaudited Condensed Consolidated Financial Statements include valuation allowances, valuation of goodwill and intangible assets, valuation of long-lived assets and valuation of contingent consideration liabilities. Actual results could differ from those estimates. All references to the “Company,” “we,” “us,” and “our” mean, as a combined company, MarineMax, Inc. and its subsidiaries.
