Company Background and Basis of Presentation	1. COMPANY BACKGROUND AND BASIS OF PRESENTATION: We believe we are the world’s largest recreational boat and yacht retailer, marina operator and superyacht services company. As of September 30, 2025, we have over 120 locations worldwide, including over 70 retail dealership locations, some of which include marinas. Collectively, with the IGY acquisition, as of September 30, 2025, we own or operate over 65 marina and storage locations worldwide. Through Fraser Yachts and Northrop & Johnson, we believe we are the largest superyacht services provider, operating locations across the globe. Cruisers Yachts, Aviara luxury dayboats, and Intrepid Powerboats all manufacture boats and yachts and recognize sales through our select retail dealership locations and through independent dealers. MarineMax provides finance and insurance services through wholly owned subsidiaries and operates MarineMax Vacations in Tortola, British Virgin Islands. The Company, through a wholly owned subsidiary, New Wave Innovations, also owns Boatyard, an industry-leading customer experience digital product company, and Boatzon, a boat and marine digital retail platform. Through Newcoast Financial Services, we provide third-party financing and insurance products for boats and yachts primarily for transactions not associated with our dealership locations. We are the largest retailer of Sea Ray and Boston Whaler recreational boats which are manufactured by Brunswick Corporation (“Brunswick”). Sales of new Brunswick boats accounted for approximately 18% of our revenue in fiscal 2025. Sales of new Sea Ray and Boston Whaler boats, both divisions of Brunswick, accounted for approximately 8% and 9%, respectively, of our revenue in fiscal 2025. Brunswick is a world leading manufacturer of marine products and marine engines. We have dealership agreements with Sea Ray, Boston Whaler, Harris, and Mercury Marine, all subsidiaries or divisions of Brunswick. We also have dealer agreements with Italy-based Azimut-Benetti Group’s product line for Azimut and Benetti yachts and mega yachts. These agreements allow us to purchase, stock, sell, and service these manufacturers’ boats and products. These agreements also allow us to use these manufacturers’ names, trade symbols, and intellectual properties in our operations. The agreements for Sea Ray and Boston Whaler products, respectively, appoint us as the exclusive dealer of Sea Ray and Boston Whaler boats, respectively, in our geographic markets. In addition, we are the exclusive dealer for Azimut Yachts for the entire United States. Sales of new Azimut yachts accounted for approximately 6% of our revenue in fiscal 2025. We believe non-Brunswick brands offer a migration for our existing customer base or fill a void in our product offerings, and accordingly, do not compete with the business generated from our other prominent brands. As is typical in the industry, we deal with most of our manufacturers, other than Sea Ray, Boston Whaler, and Azimut Yachts, under renewable annual dealer agreements, each of which gives us the right to sell various makes and models of boats within a given geographic region. Any change or termination of these agreements, or the agreements discussed above, for any reason, or changes in competitive, regulatory or marketing practices, including rebate or incentive programs, could adversely affect our results of operations. Although there are a limited number of manufacturers of the type of boats and products that we sell, we believe that adequate alternative sources would be available to replace any manufacturer other than Sea Ray, Boston Whaler, and Azimut as a product source. These alternative sources may not be available at the time of any interruption, and alternative products may not be available at comparable terms, which could affect operating results adversely. General economic conditions and consumer spending patterns can negatively impact our operating results. Unfavorable local, regional, national, or global economic developments or uncertainties regarding future economic prospects could reduce consumer spending in the markets we serve and adversely affect our business. Economic conditions in areas in which we operate dealerships, particularly Florida in which we generated approximately 54%, 53% and 53% of our dealership revenue during fiscal 2025, 2024, and 2023, respectively, can have a major impact on our operations. Local influences, such as corporate downsizing, military base closings, inclement weather such as Hurricanes Harvey and Irma in 2017, Hurricane Ian in 2022, and Hurricanes Milton and Helene in 2024, environmental conditions, and specific events, such as the BP oil spill in the Gulf of Mexico in 2010, also could adversely affect, and in certain instances have adversely affected, our operations in certain markets. In an economic downturn, consumer discretionary spending levels generally decline, at times resulting in disproportionately large reductions in the sale of luxury goods. Consumer spending on luxury goods also may decline as a result of lower consumer confidence levels, even if prevailing economic conditions are favorable. Additionally, although the Federal Reserve has recently cut interest rates, its prior increases of its benchmark interest rate resulted in significantly higher long-term interest rates, which have negatively impacted, and may continue to negatively impact, our customers’ willingness or desire to purchase our products. As a result, an economic downturn or inflation could impact us more than certain of our competitors due to our strategic focus on the higher end of our market. Additionally, the current U.S. administration has imposed and may continue to impose, significant tariff actions on imports from a broad set of countries, including countries that produce certain of our products. In response to these tariffs, U.S. trading partners have imposed, or are likely to impose, their own tariffs. Further, U.S. and international tariff policies remain uncertain and difficult to predict. Due to the uncertainty in the retail environment caused by the tariffs, we have experienced decreased revenues and profits. Additional effects of these tariffs and reciprocal tariffs are uncertain, but the tariffs are likely to increase production and supply
