Item 1.01 Entry into a Material Definitive Agreement.

On June 29, 2026, MarineMax, Inc. (the “Company”) and its subsidiaries refinanced its existing Credit Agreement with Manufacturers and Traders Trust Company, as Administrative Agent, Wells Fargo Commercial Distribution Finance, LLC , as Floor Plan Agent, Swingline Lender and Issuing Bank, and the lenders party thereto, dated August 8, 2022, as amended from time to time, evidencing a $950 million floor plan facility (the “Existing Credit Facility”). The Company refinanced the Existing Credit Facility with a new facility (the “New Credit Facility”) pursuant to an Amended and Restated Credit Agreement with Manufacturers and Traders Trust Company as Administrative Agent, Swingline Lender, and Issuing Bank, Wells Fargo Commercial Distribution Finance, LLC, as Floor Plan Agent, and the lenders party thereto (the “New Credit Agreement”). The New Credit Agreement, among other things, maintains the size of the floor plan facility at $950 million and establishes a revolving credit facility in the maximum amount of $150 million (including a $20 million swingline facility and a $20 million letter of credit sublimit), a $302.5 million term loan facility and an $85 million delayed draw mortgage loan facility. The maturity of each of the facilities is June 2031. The interest rate is (a) for amounts outstanding under the floor plan facility, 3.25% above the one month secured term rate as administered by the CME Group Benchmark Administration Limited (CBA) (“SOFR”), (b) for amounts outstanding under the revolving credit facility or the term loan facility, a range of 1.50% to 2.0%, depending on the total net leverage ratio, above the one month, three month, or six month term SOFR rate, and (c) for amounts outstanding under the mortgage loan facility, 2.20% above the one month, three month, or six month term SOFR rate. The alternate base rate with a margin is available for amounts outstanding under the revolving credit, term, and mortgage loan facilities and the Euro Interbank Offered Rate plus a margin is available for borrowings in Euro or other currencies other than dollars under the revolving credit facility.

The New Credit Facility is secured by the Company’s personal property assets, including inventory and related accounts receivable. The mortgage loans will also be secured by the real estate pledged as collateral for such loans. Substantially all of the lenders under the New Credit Facility (or their affiliates) have various other relationships with the Company and its subsidiaries involving the provision of financial services, including cash management, loans, letters of credit and bank guarantee facilities, investment banking and trust services, and some may serve as a source of retail financing for the Company’s customers. In addition, some of the lenders under the New Credit Facility (or their affiliates) were also lenders under the Existing Credit Facility

This description of the New Credit Facility is qualified in its entirety by reference to the complete terms and conditions of the New Credit Facility which is expected to be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for its fiscal quarter ended June 30, 2026.
