ACQUISITIONS AND INVESTMENTS	ACQUISITIONS AND INVESTMENTS Cyco On April 28, 2022, the Company’s Hawthorne segment completed the acquisition of substantially all of the assets of S.J. Enterprises PTY LTD, d.b.a. Cyco, an Australia-based provider of premium nutrients, additives and growing media products for indoor growing, for an estimated purchase price of $37.4. The purchase price includes contingent consideration, a non-cash investing activity, with an initial fair value of $3.1 and a maximum payout of $10.0, which will be paid by the Company based on the achievement of certain performance metrics through December 31, 2024. Prior to the transaction, the Company served as the exclusive distributor of Cyco’s products in the United States. The valuation of the acquired assets included (i) $1.3 of inventory, (ii) $10.5 of finite-lived identifiable intangible assets and (iii) $25.6 of tax-deductible goodwill. Identifiable intangible assets included trade names, customer relationships and non-compete agreements with useful lives ranging between 5 and 25 years. The estimated fair values of the identifiable intangible assets were determined using an income-based approach, which includes market participant expectations of cash flows that an asset will generate over the remaining useful life discounted to present value using an appropriate discount rate. Luxx Lighting On December 30, 2021, the Company’s Hawthorne segment completed the acquisition of substantially all of the assets of Luxx Lighting, Inc., a leading provider of lighting products for indoor growing. The purchase price was $213.2, a portion of which was paid by the issuance of 0.1 million of the common shares, $0.01 par value per share, of Scotts Miracle-Gro (“Common Shares”), a non-cash investing and financing activity, with a fair value of $21.0 based on the share price at the time of payment. During the second quarter of fiscal 2022, the Company identified quality issues with certain Luxx products sold prior to the closing of the acquisition. As of July 2, 2022, the accrual for product return refund liabilities and warranty claims associated with these quality issues was $8.9, which was recognized as a measurement-period adjustment. During the third quarter of fiscal 2022, the preliminary valuation of the acquired assets was revised to reflect updated acquisition-date assumptions including the longer duration and increased significance of lower sales volumes and cost increases. The Company recognized the resulting impact as a measurement-period adjustment. The revised valuation resulted in a decrease in the value of finite-lived identifiable intangible assets of $59.5 and a corresponding increase in goodwill. The revised valuation of the acquired assets included (i) $32.8 of inventory and accounts receivable, (ii) $5.7 of current assets, (iii) $24.2 of current liabilities, (iv) $47.3 of finite-lived identifiable intangible assets and (v) $151.6 of tax-deductible goodwill. Identifiable intangible assets included trade names, customer relationships and non-compete agreements with useful lives ranging between 5 and 25 years. The estimated fair values of the identifiable intangible assets were determined using an income-based approach, which includes market participant expectations of cash flows that an asset will generate over the remaining useful life discounted to present value using an appropriate discount rate. True Liberty Bags On December 23, 2021, the Company’s Hawthorne segment completed the acquisition of substantially all of the assets of True Liberty Bags, a leading provider of liners and storage solutions to dry and cure plant products, for $10.1. The valuation of the acquired assets included (i) $1.1 of inventory, (ii) $5.8 of finite-lived identifiable intangible assets and (iii) $3.2 of tax-deductible goodwill. Identifiable intangible assets included trade names and customer relationships with useful lives of 15 years. The estimated fair values of the identifiable intangible assets were determined using an income-based approach, which includes market participant expectations of cash flows that an asset will generate over the remaining useful life discounted to present value using an appropriate discount rate. Hydro-Logic On August 27, 2021, the Company’s Hawthorne segment completed the acquisition of substantially all of the assets of Hydro-Logic Purification Systems, Inc., a leading provider of products, accessories and systems for water filtration and purification, for $65.3. The valuation of the acquired assets included (i) $4.5 of inventory and accounts receivable, (ii) $1.6 of noncurrent assets, (iii) $2.6 of other liabilities, (iv) $23.1 of finite-lived identifiable intangible assets and (v) $38.7 of tax-deductible goodwill. Identifiable intangible assets included trade names, customer relationships and non-compete agreements with useful lives ranging between 5 and 15 years. The estimated fair values of the identifiable intangible assets were determined using an income-based approach, which includes market participant expectations of cash flows that an asset will generate over the remaining useful life discounted to present value using an appropriate discount rate. The Hawthorne Collective On August 24, 2021, the Company’s wholly-owned subsidiary, The Hawthorne Collective, Inc. (“THC”), made its initial investment under the Company’s strategic minority non-equity investment initiative in the form of a $150.0 six-year convertible note issued to the Company by Toronto-based RIV Capital Inc. (“RIV Capital”) (CSE: RIV) (OTC: CNPOF), a cannabis investment and acquisition firm listed on the Canadian Securities Exchange. The note accrues interest at 2 percent annually for the first two years and provides additional follow-on investment rights. Accrued interest will be payable to THC at maturity or will be included in the conversion value of the note at the time of conversion. The conversion feature is based upon the RIV Capital closing stock price on August 9, 2021. In connection with the Company’s investment, RIV Capital increased the size of its board of directors from four to seven members and added three nominees of the Company to the board of directors of RIV Capital. On April 22, 2022, pursuant to its follow-on investment rights, the Company made an additional investment in RIV Capital in the form of a $25.0 convertible note. The note accrues interest at 2 percent annually for the first two years and matures on August 24, 2027. Accrued interest will be payable to THC at maturity or will be included in the conversion value of the note at the time of conversion. The conversion feature is based upon the RIV Capital closing stock price on March 29, 2022. Additionally, RIV Capital is expected to increase the size of its board of directors to nine members, which is expected to include four nominees of the Company. The initial and follow-on investments would provide the Company with approximately 42 percent ownership of RIV Capital if it exercises the conversion features of both investments. The Company will not have control of or an active day-to-day role in RIV Capital or any of the companies in which RIV Capital invests. RIV Capital has agreed to use the funds it receives from the Company for general corporate and other lawful purposes, which could include acquisitions, and has agreed that the funds will not be used in connection with or for any cannabis or cannabis-related operations in the U.S. unless and until such operations comply with all applicable U.S. federal laws. During the fourth quarter of fiscal 2021, THC made minority non-equity investments of $43.1 in other entities focused on branded cannabis and high quality genetics. These additional investments also include conversion features that would provide the Company with minority ownership interests if it exercises the conversion features, as well as restrictions that the funds will not be used in connection with or for any cannabis or cannabis-related operations in the U.S. unless and until such operations comply with all applicable U.S. federal laws.

The valuation of the acquired assets included (i) $0.6 of inventory, (ii) $10.9 of finite-lived identifiable intangible assets and (iii) $22.2 of tax-deductible goodwill. Identifiable intangible assets included trade names, customer relationships and non-compete agreements with useful lives ranging between 5 and 25 years. The estimated fair values of the identifiable intangible assets were determined using an income-based approach, which includes market participant expectations of cash flows that an asset will generate over the remaining useful life discounted to present value using an appropriate discount rate.
