2024 Acquisition

On September 12, 2024, the Company acquired additional Freedom Boat Club franchise operations and territories in Southeast Florida. The acquisition enhances Freedom Boat Club's presence in Florida and provides an opportunity to leverage synergies across Brunswick's portfolio of brands. The acquisition is included as part of the Company's Boat segment.

The Company paid net cash consideration of $31.2 million for the acquisition. The opening balance sheet, which is preliminary and subject to change in the measurement period as the Company finalizes the purchase price allocation and fair value estimates, includes $26.7 million of goodwill and $5.2 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 the acquisition were not material to the Company's consolidated results of operations. The acquisition is 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 acquisition, and pro forma results for prior periods are not presented.
