October 8, 2019 Austin Singleton Chief Executive Officer OneWater Marine Inc. 6275 Lanier Islands Parkway Buford, GA 30518 Re: OneWater Marine Inc. Supplemental Response Submitted October 3, 2019 Registration Statement on Form S-1 File No. 333-232639 Dear Mr. Singleton: We have reviewed your correspondence and have the following comments. In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by amending your registration statement and providing the requested information. If you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing any amendment to your registration statement and the information you provide in response to these comments, we may have additional comments. Correspondence submitted October 3, 2019 in connection with Registration Statement on Form S-1 Dilution, page 56 1. Please tell us how you computed net tangible book value and net tangible book value per share as of June 30, 2019, after giving pro forma effect to the transactions described under "Corporate Reorganization." Reconcile the amounts used in your calculation to the pro forma balance sheet as of June 30, 2019 and explain why your calculation appropriately considers the Redeemable Preferred interest in subsidiary. 2. Reference is made to your response to comment 6 in our letter dated July 30, 2019 that you will reconcile the total consideration paid by legacy owners with the pro forma consolidated balance sheet in a future filing so that the figures are consistent. It appears Austin Singleton OneWater Marine Inc. October 8, 2019 Page 2 that the amounts still do not reconcile; therefore we reissue our comment. In that regard, reference is made to the second table on page 56. Please tell us how you determined total consideration paid by legacy owners. Please also explain how to reconcile total consideration to the unaudited pro forma consolidated balance sheet as of June 30, 2019 on page 60. Unaudited Pro Forma Consolidated Balance Sheet as of June 30, 2019, page 60 3. Please provide us with the journal entries for adjustments (2) - (7). Please also explain why adjustment (6) is impacting the offering adjustments column. Finally, revise to add footnote (2) to the equity account impacted. Unaudited Pro Forma Consolidated Statements of Operations For the Nine Months Ended June 30, 2019, page 62 4. Please tell us how you computed the income tax adjustments in the offering adjustment columns in the unaudited pro forma consolidated statements of operations for the nine months ended June 30, 2019 and year ended September 30, 2019. Explain why the adjustment is so large in comparison to the interest expense adjustment. 5. We note your disclosure in pro forma adjustment (2) that the effective tax rate is 24.7%. Based on the pro forma income tax expense as adjusted for the reorganization and the pro forma income tax expense as adjusted for the offering for the nine months ended June 30, 2019, the effective tax rate appears to be 21.3%. Please revise or advise. Further, we note that the 21.3% effective tax rate presented in the unaudited pro forma consolidated statements of operations for the nine months ended June 30, 2019 differs from the 24.7% effective tax rate used in pro forma adjustment (8) on page 65. Please revise or advise. Please note that this comment is also applicable to your unaudited pro forma consolidated statements of operations for the year ended September 30, 2018. 6. Please tell us why pro forma diluted net income per Class A common stock as disclosed on the face of the unaudited pro forma consolidated statements of operations differs from what is disclosed in Note (8). In regard to the amounts in Note (8), explain why pro forma basic and diluted net income per Class A common stock should be different. 7. Please tell us why the One Water LLC Historical column does not reflect Redeemable Preferred interest, dividend and accretion as well as One Water LLC preferred distributions in order to calculate net income attributable to common interest holders. We have the same question for the One Water Marine Holdings, LLC and Subsidiaries Condensed Consolidated Statements of Operations presented on page F-3 of Amendment No. 2 to Form S-1 filed on September 23, 2019.
