Group 1 Automotive’s agreement to acquire Hennessy Automobile Companies marks the largest 10-store deal by dollar value in automotive retail history. The $1.3 billion transaction adds 10 luxury and import dealerships in metro Atlanta to Group 1’s portfolio and marks the city as the company’s second-largest market by revenue. Kerrigan Advisors brokered the deal on behalf of the Hennessy family, whose 60-year-old dealership group built its business on premium luxury brands in the Southeast.
On the latest Inside Automotive episode, we sat down with Ryan Kerrigan, Managing Director at Kerrigan Advisors, following the announcement of the record-setting deal. Kerrigan broke down what the transaction says about the state of the buy-sell market and why luxury dealerships are commanding record valuations.
