Earnings per share for the nine months ended September 30, 2025, was adversely impacted by non-cash goodwill and franchise rights impairments. See Notes 8 and 14 of the Notes to Unaudited Condensed Consolidated Financial Statements for more information.

In June 2024, our business was impacted by an outage of our dealer management system provided by CDK Global, which is used to support our dealership operations, including our sales, service, inventory, customer relationship management, and accounting functions. Access to core functions of this system was restored by the end of June 2024, and certain ancillary systems and integrations were restored by the end of July 2024, with residual impacts resolved by the end of the third quarter of 2024. As a result, our results of operations and earnings per share were negatively impacted by one-time compensation costs paid to commission-based associates to ensure business continuity in the second quarter of 2024 and by lost income from the disruption to our operations in the second and third quarters of 2024.
