Equity Method Investments and Joint Ventures [Abstract]
INVESTMENT IN UNCONSOLIDATED AFFILIATES	INVESTMENT IN UNCONSOLIDATED AFFILIATES Bonnie Plants The Company holds a 50% equity interest in Bonnie Plants, LLC, a joint venture with AFC focused on planting, growing, developing, distributing, marketing and selling live plants. During the three months ended December 31, 2022, the Company and AFC amended the joint venture agreement to allow AFC to make an additional equity contribution to Bonnie Plants, LLC, and, as a result of this contribution by AFC, the Company’s equity interest in Bonnie Plants, LLC was reduced to 45%. On November 7, 2023, the Company purchased an additional 5% equity interest in Bonnie Plants, LLC from AFC for $21.4, which restored its total equity interest back to 50%. The Company’s interest is accounted for using the equity method of accounting, with the Company’s proportionate share of Bonnie Plants, LLC earnings reflected in the Consolidated Statements of Operations. During fiscal 2025, fiscal 2024 and fiscal 2023, the Company recorded equity in (income) loss of unconsolidated affiliates associated with Bonnie Plants, LLC of $(5.4), $68.1 and $101.1, respectively. The Company recorded pre-tax impairment charges of $61.9 and $94.7 during fiscal 2024 and fiscal 2023, respectively, associated with its investment in Bonnie Plants, LLC in the “Equity in loss of unconsolidated affiliates” line in the Consolidated Statements of Operations. The impairment charges were driven by revisions to the Company’s internal forecasts for Bonnie Plants, LLC. The estimated fair value of Bonnie Plants, LLC for purposes of the impairment assessment was based upon an equal weighting of the income-based and market-based approaches, utilizing estimated cash flows and a terminal value, discounted at a rate of return that reflects the relative risk of the cash flows, as well as valuation multiples derived from comparable publicly traded companies that are applied to the operating performance of the investment. The fair value estimates utilize significant unobservable inputs and thus represent Level 3 fair value measurements. As a result of the impairment charges recorded by the Company during fiscal 2024 and fiscal 2023, the carrying value of the Company’s equity method investment is lower than its interest in Bonnie Plants, LLC’s underlying net assets as of September 30, 2025. Of this basis difference, the majority relates to goodwill and indefinite-lived intangible assets recorded by Bonnie Plants, LLC, which are not amortized. The remaining amount relates to long-lived assets, including finite-lived intangible assets, and will be amortized over the remaining useful life of the long-lived assets. FLUENT On December 19, 2024, FLUENT acquired all of the issued and outstanding common shares of RIV Capital in exchange for FLUENT shares (the “Transaction”). In connection with the Transaction, FLUENT and THC entered into an exchange and protection agreement on December 18, 2024, pursuant to which THC exchanged its existing convertible debt investment in RIV Capital for 153.1 million non-voting exchangeable shares of FLUENT. On July, 18, 2025, THC, which was acquired by BDH in March 2025, converted its non-voting exchangeable shares into 153.1 million common shares of FLUENT, which represents approximately 25% of FLUENT’s total outstanding common shares as of September 30, 2025. THC and FLUENT are also parties to an investor rights agreement which allows THC to nominate up to two members to the FLUENT board of directors, and provides THC with certain participation rights in order to maintain its pro rata investment position in FLUENT in connection with any offering of FLUENT shares. THC’s convertible debt investment in RIV Capital, which was previously recorded in the “Other assets” line in the Consolidated Balance Sheets, had a carrying value of $17.7 on December 18, 2024. The exchange of the RIV Capital convertible debt investment for non-voting exchangeable shares of FLUENT, a non-cash investing and financing activity, resulted in a loss of $7.0 that was recorded in the “Impairment, restructuring and other” line in the Consolidated Statements of Operations during fiscal 2025. THC’s interest in FLUENT had an initial fair value of $10.7 and is recorded in the “Investment in unconsolidated affiliates” line in the Consolidated Balance Sheets. The estimated fair value of the non-voting exchangeable shares of FLUENT was determined based upon the quoted market price of FLUENT common shares as of the date of the exchange and represents a Level 2 nonrecurring fair value measurement. This investment is accounted for using the equity method of accounting, with THC’s proportionate share of FLUENT earnings subsequent to December 18, 2024 reflected in the Consolidated Statements of Operations on a one quarter lag. During fiscal 2025, the Company recorded equity in loss of unconsolidated affiliates associated with FLUENT of $8.2. Refer to “NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES” for further details related to the Company’s sale of THC to BDH on March 14, 2025. BDH is a variable interest entity that is consolidated by the Company.
