Acquisitions

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 $28.2 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.

2023 Acquisitions

During the fourth quarter of 2023, the Company acquired additional Freedom Boat Club franchise operations and territories in the Southeast United States. These acquisitions should unlock operational efficiencies while providing members with additional boating destinations, as the Company plans for continued expansion across the Southeast Coastal region. These acquisitions are included as part of the Company's Boat segment.

The Company paid net cash consideration of $16.0 million for these acquisitions. The opening balance sheets, which are preliminary and subject to change in the measurement period as the Company finalizes the purchase price allocation and fair value estimates, include $12.9 million of goodwill and $3.3 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 were not material to the Company's consolidated results of operations.

On September 1, 2023, the Company acquired all of the issued and outstanding shares of Fliteboard Pty Ltd (Fliteboard) for $88.3 million net cash consideration. Fliteboard is a leader in eFoiling technology, which combines advanced hydrofoils and electric propulsion on the water. The acquisition of Fliteboard allows the Company to enter the emerging electric-foiling surfboard market and presents the opportunity for technological, manufacturing, commercial and consumer synergies with our existing portfolio. Fliteboard is included as part of the Company's Propulsion segment.

The opening balance sheet includes $38.0 million of goodwill, $20.7 million of trade names, $8.4 million of customer relationships, and $7.1 million of developed technology. The amounts assigned to customer relationships and developed technology will be amortized over the estimated useful lives of 15 years and 10 years, respectively. Transaction costs associated with the acquisition of $1.9 million were expensed as incurred within Selling, general and administrative expense in 2023. Purchase accounting is final as of September 28, 2024.

These 2023 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.
