In your response to comment 1, you cite certain synergies--such as dealer agreements, fulfilling customer sales orders, management personnel, marketing, and other shared administrative resources--as part of your conclusion that each region is the lowest level of independent cash flows. Please explain in greater detail each of these synergies, including: specifically how each synergy operates within a region; W. Brett McGill MarineMax, Inc. April 15, 2020 Page 2 why these synergies are of such significance that each location within a region is dependent on the other locations within that region; and why these synergies make the lower-level cash flows of the locations not largely independent of each other. 2. In your response to comment 1, you indicate that dealer agreements are aligned at the regional level and not at the retail location level. With a focus on your more significant dealer agreements (including, but not limited to, Brunswick Corporation and Azimut- Benetti Group), please elaborate further and tell us: the nature of these dealer agreements (e.g., what they entail, approximate number of agreements, their size and scope, etc.); whether each region has separate/freestanding dealer agreements or the agreements are negotiated centrally/nationally; and whether the dealer agreements align perfectly with your regions, whether certain dealer agreements encompass only portions of a region, or whether there is overlap encompassing several regions. You may contact James Giugliano at (202) 551-3319 or Rufus Decker at (202) 551- 3769 if you have any questions. FirstName LastNameW. Brett McGill Sincerely, Comapany NameMarineMax, Inc.
