FOR IMMEDIATE RELEASE

Group 1 Automotive Reports Record Revenues and Gross Profit in the Second Quarter of 2025

•Current quarter diluted earnings per common share from continuing operations of $10.77 and current quarter adjusted diluted earnings per common share from continuing operations (a non-GAAP measure) of $11.52, increases of 6.1% and 17.5%, respectively, over the comparable prior year quarter

•Total revenues and gross profit of $5.7 billion and $935.8 million, both quarterly records, increased 21.4% and 22.1%, respectively, over the comparable prior year quarter

•Parts and service gross profit of $402.8 million (as reported) and $355.1 million (on a same store basis), increased 27.1% and 14.0%, respectively, over the comparable prior year quarter, with strong customer pay same store revenue growth exceeding 13.6% in the U.S. and U.K.

HOUSTON, TX, July 24, 2025 — Group 1 Automotive, Inc. (NYSE: GPI) (“Group 1” or the “Company”), a Fortune 250 automotive retailer with 258 dealerships located in the U.S. and U.K., today reported financial results for the second quarter of 2025 (“current quarter”).

“We were pleased with our growth in the second quarter. Same store revenues increased 7.1%. Parts and service was a bright spot in both markets, driven by double digit same store growth in customer pay and a tailwind from warranty. F&I was also a good story, especially in the U.K. where same store gross profit per unit rose over 26%, and we closed on three outstanding dealerships in the U.S.,” said Daryl Kenningham, Group 1’s President and Chief Executive Officer.

“The U.K. market continues to be challenging in terms of industry volumes and with BEV mandate-related margin pressures. Integration efforts are largely complete, and most U.K. brands are performing to expectations, with positive momentum anticipated in the second half of the year. SG&A leverage improvement remains a focus in the U.K., with room for further gains.

We’ll continue to pursue balanced growth while executing opportunistic share repurchases. Additionally, we’re actively reviewing underperforming stores and developing appropriate plans.”

Reconciliations for financial results, non-GAAP metrics and diluted earnings per common share between continuing and discontinued operations are included in the accompanying financial tables.

Current Quarter Results Overview

•Total revenues for the current quarter were $5.7 billion, a 21.4% increase compared to $4.7 billion for the second quarter of 2024 (“prior year quarter”).

•Net income from continuing operations for the current quarter was $139.8 million, a 1.4% increase compared to $137.9 million for the prior year quarter.

•Current quarter adjusted net income from continuing operations (a non-GAAP measure) was $149.6 million, a 12.4% increase compared to $133.1 million for the prior year quarter.

•Current quarter diluted earnings per common share from continuing operations was $10.77, a 6.1% increase compared to $10.15 for the prior year quarter. Current quarter adjusted diluted earnings per common share from continuing operations (a non-GAAP measure) was $11.52, a 17.5% increase compared to $9.80 for the prior year quarter.

FORWARD-LOOKING STATEMENTS

This press release 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. These forward-looking statements often contain words such as "expects," "anticipates," "intends," "plans," "believes," "seeks," "should," "foresee," "may" or "will" and similar expressions. 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. (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, (j) our ability to successfully integrate recent and future acquisitions and realize the expected benefits from consummated acquisitions, (k) foreign exchange controls and currency fluctuations, (l) 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.

NON-GAAP FINANCIAL MEASURES, SAME STORE DATA, AND OTHER DATA

In addition to evaluating the financial condition and results of our operations in accordance with U.S. GAAP, from time to time our management evaluates and analyzes results and any impact on the Company of strategic decisions and actions relating to, among other things, cost reduction, growth, profitability improvement initiatives, and other events outside of normal, or "core," business and operations, by considering alternative financial measures not prepared in accordance with U.S. GAAP. In our evaluation of results from time to time, we exclude items that do not arise directly from core operations, such as non-cash asset impairment charges, out-of-period adjustments, legal matters, gains and losses on dealership franchise or real estate transactions, and catastrophic events, such as hailstorms, hurricanes and snow storms, and employment compensation costs associated with the cybersecurity incident experienced by third-party software provider, CDK Global LLC in June 2024. Because these non-core charges and gains materially affect the Company's financial condition or results in the specific period in which they are recognized, management also evaluates, and makes resource allocation and performance evaluation decisions based on, the related non-GAAP measures excluding such items. This includes evaluating measures such as adjusted selling, general and administrative expenses, adjusted net income, adjusted diluted earnings per share, and constant currency. These adjusted measures are not measures of financial performance under U.S. GAAP, but are instead considered non-GAAP financial performance measures. Non-GAAP measures do not have definitions under U.S. GAAP and may be defined differently by, and not be comparable to similarly titled measures used by, other companies. As a result, any non-GAAP financial measures considered and evaluated by management are reviewed in conjunction with a review of the most directly comparable measures calculated in accordance with U.S. GAAP. We caution investors not to place undue reliance on such non-GAAP measures, but also to consider them with the most directly comparable U.S. GAAP measures.

In addition to using such non-GAAP measures to evaluate results in a specific period, management believes that such measures may provide more complete and consistent comparisons of operational performance on a period-over-period historical basis and a better indication of expected future trends. Our management also uses these adjusted measures in conjunction with U.S. GAAP financial measures to assess our business, including communication with our Board of Directors, investors, and industry analysts concerning financial performance. We disclose these non-GAAP measures, and the related reconciliations, because we believe investors use these metrics in evaluating longer-term period-over-period performance, and to allow investors to better understand and evaluate the information used by management to assess operating performance. The exclusion of certain expenses in the calculation of non-GAAP financial measures should not be construed as an inference that these costs are unusual or infrequent. We anticipate excluding these expenses in the future presentation of our non-GAAP financial measures.

In addition, we evaluate our results of operations on both an as reported and a constant currency basis. The constant currency presentation, which is a non-GAAP measure, excludes the impact of fluctuations in foreign currency exchange rates. We believe providing constant currency information provides valuable supplemental information regarding our underlying business and results of operations, consistent with how we evaluate our performance. We calculate constant currency percentages by converting our current period reported results for entities reporting in currencies other than U.S. dollars using comparative period exchange rates rather than the actual exchange rates in effect during the respective periods. The constant currency performance measures should not be considered a substitute for, or superior to, the measures of financial performance prepared in accordance with U.S. GAAP. The Same Store amounts presented include the results of dealerships for the identical months in each period presented in comparison, commencing with the first full month in which the dealership was owned by us and, in the case of dispositions, ending with the last full month it was owned by us. Same Store results also include the activities of our corporate headquarters.

Certain amounts in the financial statements may not compute due to rounding. All computations have been calculated using unrounded amounts for all periods presented.
