This presentation contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, which are statements related to future, not past, events and are based on our current expectations and assumptions regarding our business, the economy and other future conditions. In this context, the forward-looking statements often include statements regarding our strategic investments, goals, plans, projections and guidance regarding our financial position, results of operations and business strategy, including the annualized revenues of recently completed acquisitions or dispositions and other benefits of such currently anticipated or recently completed acquisitions or dispositions.

While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting us will be those that we anticipate. Any such forward-looking statements are not assurances of future performance and involve risks and uncertainties that may cause actual results to differ materially from those set forth in the statements. These risks and uncertainties include, among other things, (a) general economic and business conditions, (b) the impacts of sustained levels of inflation, (c) developments in U.S. and global trade policy, including the imposition by the U.S. of significant tariffs on the import of automobiles and certain materials used in our parts and services business and the resulting consequences (including, but not limited to, retaliatory tariffs by non-U.S. nations, supply chain disruptions, vehicle and part cost increases and demand decreases and potential recessions in the U.S. and U.K.), (d) the level of manufacturer incentives, (e) our ability to comply with extensive laws, regulations and policies applicable to our operations, including BEV mandates in the U.K. and their impact on new vehicle demand, (f) our ability to obtain an inventory of desirable new and used vehicles (including as a result of changes in the international trade environment), (g) our relationship with our automobile manufacturers and the willingness of manufacturers to approve future acquisitions, (h) our cost of financing and the availability of credit for consumers, (i) our ability to complete acquisitions and dispositions, on a timely basis, if at all and the risks associated therewith, §) our ability to successfully integrate recent and future acquisitions and realize the expected benefits from consummated acquisitions, (k) foreign exchange controls and currency fluctuations, (I) the armed conflicts in Ukraine and the Middle East, (m) our ability to maintain sufficient liquidity to operate, and (n) a material failure in or breach of our vendors' information technology systems and other cybersecurity incidents.

For additional information regarding known material factors that could cause our actual results to differ from our projected results, please see our filings with the Securities and Exchange Commission, including our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise.

Performance to Achieve

Operational Excellence Lowers

Our strategy generates

in-market efficiencies (used vehicle purchasing / transfers / reconditioning, marketing spend and impact, loyalty program, customer experience center)

Standardization across rooftops structurally lowers costs company-wide (warranty operating model, technician acquisition and retention, procurement, used vehicle purchasing and service-to-sales integration)

Increased scale through M&A leverages this impact

GPI is currently in its strongest position of the decade in collective Customer Satisfaction, Service Loyalty and Sales Expectancy performance
