FOR IMMEDIATE RELEASE

Group 1 Automotive Announces Third Quarter 2019 Financial Results

U.S. Revenue Jumps 10% Driven by 15% Used Vehicle Growth

HOUSTON, October 24, 2019 - Group 1 Automotive, Inc. (NYSE: GPI), (“Group 1” or the “Company”),an international, Fortune 500 automotive retailer, today reported 2019 third quarter net income of $38.0 million, diluted earnings per common share of $2.04, adjusted net income (a non-GAAP measure) of $56.4 million, and adjusted diluted earnings per common share (a non-GAAP measure) of $3.02. The Company’s 2019 third quarter total revenue was an all-time quarterly record of $3.1 billion.

Third quarter 2019 adjusted net income and diluted earnings per share exclude approximately $18.4 million of net after-tax adjustments, or $0.98 per common share, for non-core items. These adjustments consist of catastrophic event costs of approximately $9.0 million after-tax, or $0.48 per common share, non-cash asset impairments of $8.3 million, or $0.44 per common share, and a net loss on real estate and dealership transactions of $1.1 million, or $0.06 per common share. Reconciliations of non-GAAP financial measures are included in the attached financial tables.

“Our achievement of new quarterly records for total revenue and adjusted EPS in a flat U.S. new vehicle sales market, as well as a U.K. market in political turmoil, is a testimony to the strong operating execution of our entire team - especially in the U.S.,” said Earl J. Hesterberg, Group 1’s president and chief executive officer. “Same Store U.S. gross profit growth of 16.6% in total used vehicles and 9.9% in parts and service are both remarkable performances, which drove one of the best quarters in our Company’s history.”

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 goals, plans, projections and guidance regarding our financial position, results of operations, market position, pending and potential future acquisitions and business strategy, and 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 level of manufacturer incentives, (c) the future regulatory environment, (d) our ability to obtain an inventory of desirable new and used vehicles, (e) our relationship with our automobile manufacturers and the willingness of manufacturers to approve future acquisitions, (f) our cost of financing and the availability of credit for consumers, (g) our ability to complete acquisitions and dispositions and the risks associated therewith, (h) foreign exchange controls and currency fluctuations, (i) our ability to retain key personnel, and (j) uncertainty of the outcome and potential impact of Brexit. 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 SEC, 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, legal matters, gains and losses on dealership franchise or real estate transactions, and catastrophic events, such as hailstorms, hurricanes, and snow storms. 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 income 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 disclosures are reported as zero balances or may not compute due to rounding.
