2022 Acquisitions

During the second quarter of 2022, the Company acquired certain Freedom Boat Club franchise operations and territory rights as well as certain marine assets in the Southeast United States. These acquisitions enable opportunities across a wide spectrum, building upon the growth Brunswick has cultivated throughout the Company's shared access portfolio and new digital platforms. These acquisitions are included as part of the Company's Boat segment.

The Company paid net cash consideration of $93.9 million for these acquisitions. The opening balance sheets include $71.4 million of goodwill and $11.9 million of customer relationships. The amount assigned to customer relationships will be amortized over the estimated useful life of 10 years. Transaction costs associated with these acquisitions of $1.4 million were expensed as incurred within Selling, general and administrative expense in 2022. The acquisitions are not material to the Company's net sales, results of operations, or total assets during any period presented. Accordingly, the Company's consolidated results of operations do not differ materially from historical performance as a result of the acquisitions, and pro forma results for prior periods are not presented. Purchase accounting for these acquisitions is final as of July 1, 2023.
