Atlanta's dealership landscape is headed for a major corporate reshuffle: Houston-based Group 1 Automotive has agreed to acquire Hennessy Automobile Companies' dealership assets and real estate in a transaction valued at approximately $1.3 billion. If it closes, 10 Hennessy stores will move under Group 1's ownership, giving the publicly traded retailer a much bigger foothold across metro Atlanta.
Group 1 announced the agreement Thursday as part of its push to build dealership clusters in high-growth markets. The company expects the acquisition to add roughly $1.7 billion in annualized revenue and says it should immediately boost earnings per share once completed.
The transaction includes Hennessy's Lexus, Jaguar/Land Rover and Porsche operations, plus facilities with 500 service bays and about 280 technicians, according to PR Newswire. That makes this far more than a name change on a roadside sign: it is a large sales-and-service network being folded into Group 1's existing infrastructure.
Atlanta Becomes Group 1's Second-Biggest Market
Group 1 says its Atlanta footprint will grow from three dealerships to 15 when the Hennessy deal is combined with its recent Stone Mountain Honda and Toyota acquisitions. The expansion would make Atlanta the company's second-largest U.S. market by revenue and its ninth U.S. market with at least five stores.
For Hennessy, the deal marks a major turn for a family business that says it has served metro Atlanta since 1964. The company's own history describes a network built around vehicle sales, service and leasing, with locations spread across Atlanta and surrounding suburbs, according to Hennessy Auto.
Group 1 has already been adding Atlanta luxury inventory: the company acquired Mercedes-Benz of Buckhead in August 2025, a move it said would generate about $210 million in annual revenue, according to a filing posted by the U.S. Securities and Exchange Commission. The Hennessy purchase would dwarf that earlier expansion in both store count and projected revenue.
The transaction is expected to close by year-end 2026, but the handoff still depends on regulatory approvals, automaker approvals and other customary closing conditions. Group 1 plans to finance the purchase with new debt backed by a bridge commitment, per the company's transaction announcement. Peter Hennessy said the family believes Group 1 will continue the company's Atlanta legacy and customer-focused approach.
