Lithia Motors is a retailer of new and used vehicles and related services. The company offers nearly 60 brands of vehicles at nearly 500 stores globally across the US, Canada, and UK. The company has expanded largely through the acquisition of dealerships in smaller regional markets but now seeks to grow in any part of the US and we expect more deals over time in the US and, at times, abroad. Annual revenue in 2025 was $37.6 billion and we see over $50 billion possible in a few years. The US was 78.5% of 2025 revenue and the UK second at 18.4%, due to the 2024 Pendragon acquisition. In 2025, new vehicle sales were about 50% of total revenue. Lithia was founded in 1946, went public in 1996, and is the largest US auto dealer. It is based in Medford, Oregon.
