Item 1.01 Entry into a Material Definitive Agreement.

Purchase Agreement

On July 30, 2026, Group 1 Automotive, Inc., a Delaware corporation (the “Company”), entered into a Purchase and Sale Agreement (the “Purchase Agreement”) with Hennessy Automobile Companies, Inc., a Georgia corporation, Telalee Partners, Inc., a Georgia corporation, Woodhaven Partners, LLC, a Georgia limited liability company, Woodhaven Partners II, Inc., a Georgia corporation, Hennessy Cadillac, Inc., a Georgia corporation, Tuxedo Partners, Inc., a Georgia corporation, Valley Partners, Inc., a Georgia corporation, and Berwyn Partners, Inc., a Georgia corporation (each, a “Seller” and collectively, the “Sellers”), and the affiliated real estate holding entities identified therein (collectively with the Sellers, the “Seller Parties” and, together with their respective subsidiaries, the “Selling Entities”), and, solely for certain limited purposes, Peter R. Hennessy, Mark W. Hennessy and Stephen R. Hennessy (collectively, the “Principals”). The Selling Entities, collectively, are engaged in (i) the operation of ten automobile dealerships and one collision center located in the greater Atlanta, Georgia market, (ii) owning and leasing real estate to related to automobile dealerships and (iii) selling and providing products and services related to the operation of automobile dealerships and a collision center (collectively, the “Business”).

Pursuant to the Purchase Agreement, the Company will acquire substantially all of the assets of the Selling Entities that relate to the Business (collectively, the “Transaction”). The Company expects to pay an aggregate purchase price of approximately $1.3 billion, plus an additional amount for the remaining inventory assets, to be determined based on a physical inventory conducted at or near closing, in each case subject to customary adjustments described in the Purchase Agreement (the “Purchase Price”). The Company is required to deposit $10.0 million into escrow within five business days of entering into the Purchase Agreement, subject to extension under certain circumstances, which will be credited toward the Purchase Price payable at the closing of the Transaction. At the closing of the Transaction, $80.0 million of the Purchase Price will be deposited into escrow as a contingent reserve to be used, if necessary, to compensate the Company for any post-closing indemnifiable losses pursuant to the terms of the Purchase Agreement, with 25% to be released to the Sellers three months after the closing of the Transaction, an additional 25% to be released nine months after the closing of the Transaction, and the remainder to be released 18 months after the closing of the Transaction, in each case subject to pending claims, if any.

The Purchase Agreement contains customary representations and warranties made by each of the parties, and the Company and the Seller Parties have agreed to indemnify one another against certain damages, subject to certain exceptions and limitations. The closing of the Transaction is subject to various closing conditions, including the receipt of required consents from the applicable vehicle manufacturers and receipt of approval or expiration of the waiting period required by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The Purchase Agreement also contains certain termination rights of the Company and the Sellers.

The Transaction is expected to close no later than the 160th day after the date of the Purchase Agreement (subject to extension to the 190th day after the date of the Purchase Agreement under certain circumstances relating to manufacturer consents), provided that the closing conditions are satisfied or waived. In connection with the Transaction, the Sellers and the Principals have agreed to customary non-competition and non-solicitation covenants for a period of three years following the closing of the Transaction, and the parties will enter into a trademark license agreement granting the Company a royalty-free license to use certain “Hennessy” trademarks and related intellectual property in connection with the Dealerships for a limited transition period.

In connection with, and concurrently with its entry into, the Purchase Agreement, the Company entered into a commitment letter, dated July 30, 2026 (the “Commitment Letter”), with JPMorgan Chase Bank, N.A. (“JPMorgan”), pursuant to which JPMorgan has committed, subject to the satisfaction of the conditions set forth therein, to provide the Company with a 364-day senior unsecured bridge facility (the “Bridge Facility”) in an aggregate principal amount of $1.25 billion. The Company expects to fund the Purchase Price through $1.25 billion of new debt, backstopped by a bridge commitment.

Forward-Looking Statements

This Current Report on Form 8-K 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.

Group 1 Automotive Reports Second Quarter 2026 Financial Results

•Current quarter diluted earnings per common share from continuing operations of $8.62 and current quarter adjusted diluted earnings per common share from continuing operations (a non-GAAP measure) of $9.61

•U.S. current quarter SG&A as a % of gross profit of 67.5%; U.S. current quarter adjusted SG&A as a % of gross profit (a non-GAAP measure) improved sequentially 400+ basis points to 66.4%

•Separately announces agreement to acquire 10 dealerships from Hennessy Automobile Companies and recently completed the purchase of two additional dealerships in the fast-growing Atlanta market, further strengthening our proven cluster strategy

HOUSTON, TX, July 30, 2026 — Group 1 Automotive, Inc. (NYSE: GPI) (“Group 1” or the “Company”), a Fortune 250 automotive retailer with 251 dealerships located in the U.S. and U.K., today reported financial results for the second quarter of 2026 (“current quarter”).

“While our second quarter results softened due to consumer affordability issues, we continued to execute against the strategic initiatives that will strengthen Group 1 over the long term,” said Daryl Kenningham, Group 1's President and Chief Executive Officer. “During the quarter in the U.S., we successfully completed our previously announced $50 million annualized expense reduction initiative, exceeding our targets. We also continued to invest in our future through strategic dealership acquisitions and dispositions, advanced our corporate rebranding to more than 60% completion, and expanded our virtual F&I platform to more than 40% of our stores. We remain focused on disciplined execution that will continue to drive sustainable value for our shareholders.”

“To that end, earlier today we announced our intent to acquire Hennessy Automobile Companies which, along with two additional dealership acquisitions, will boost our presence to 15 dealerships in Atlanta. The purchase of these high-volume dealerships in a tremendous growth market is the ideal execution of our cluster strategy and bolsters Group 1’s position for the long term.”

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

•Current quarter total revenues were $5.4 billion, compared to $5.7 billion for the second quarter of 2025 (“prior-year quarter”).

•Current quarter net income from continuing operations was $103.0 million, compared to $139.8 million for the prior-year quarter.

•Current quarter adjusted net income from continuing operations (a non-GAAP measure) was $114.9 million, compared to $149.6 million for the prior-year quarter.

Corporate Development

Today, in a separate press release, the Company announced that it has signed a definitive agreement to acquire the 10 dealerships of the Hennessy Automobile Companies, located in the Atlanta market. The Company expects the transaction to close by year-end 2026, subject to regulatory and OEM approvals, as well as other customary closing conditions, and generate approximately $1.7 billion in annual revenues. For additional information, see the Company’s separate press release and Current Report on Form 8-K filed in connection with this transaction.

During the current quarter, the Company acquired four dealerships in the U.S., two of which were acquired as part of a back-to-back transaction with the intention of reselling them concurrently with or shortly after acquisition. These two dealerships were classified as assets held for sale as of the end of the current quarter. The Company completed the disposition of these dealerships in July 2026. The two retained dealerships, Stone Mountain Toyota and Stone Mountain Honda, also located in the Atlanta market, are expected to generate approximately $205 million in annual revenues.

Year to date, the Company has acquired and successfully integrated dealership operations with total expected annual revenues of approximately $340 million. The Company remains focused on efficiently and effectively integrating acquisitions into existing operations to create value for shareholders.

During the current quarter, the Company disposed of four Jaguar/Land Rover dealerships in the U.K. These dealerships generated approximately $330 million in annual revenues, bringing year-to-date total annualized revenues associated with dealership dispositions for the Company to $900 million.

As previously announced, the Company entered into an agreement with Chinese automaker Geely to expand its U.K. network through three new locations. The first Geely franchise opened in June 2026, with the remaining two locations expected to open later in the year.

Share Repurchases

The Company did not repurchase any shares of its common stock during the current quarter. During the current year, the Company repurchased 205,190 shares of common stock, representing approximately 1.7% of shares outstanding as of January 1, 2026, at an average price of $353.08 per share, for a total cost of $72.4 million, excluding excise taxes of $0.5 million.

As of June 30, 2026, the Company had 11,925,913 shares of common stock and unvested restricted stock awards outstanding in the aggregate, and $306.3 million remaining under its Board authorized share repurchase program.

Future repurchases may be made from time to time, based on market conditions, legal requirements and other corporate considerations in the open market, pursuant to Rule 10b5-1 trading plans or in privately negotiated transactions, and subject to Board approval and covenant restrictions.

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 financial and other benefits of anticipated or recently completed acquisitions or dispositions, including the pending acquisition of Hennessy Automobile Companies (the “Hennessy Acquisition”), the timing and financing thereof and our ability to achieve the intended operational, financial and strategic benefits therefrom. 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, including reduced affordability of automobiles for consumers, (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.) and the passage of the "One Big Beautiful Bill," including the associated impact on tax deductions in the domestic car industry and the elimination of certain clean energy tax credits, which could impact incentives for electric vehicle production and sales, (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, including the pending Hennessy Acquisition, on a timely basis, if at all and the risks associated therewith, (j) our ability to successfully integrate recent and future acquisitions, including the Hennessy Acquisition, 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. 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, adjusted operating margin, adjusted pretax margin 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.

Exhibit 99.2

FOR IMMEDIATE RELEASE

Group 1 Agrees to Acquire Hennessy Automobile Dealerships in the Atlanta Market to Advance Proven Cluster Strategy

Expected to Add Approximately $1.7 Billion in Annualized Revenues and Be Immediately Accretive to EPS Upon Closing

HOUSTON, TX July 30, 2026 – Group 1 Automotive, Inc. (NYSE: GPI) (“Group 1” or the “Company”), a Fortune 250 automotive retailer with 251 dealerships located in the U.S. and U.K., today announced it has signed a definitive agreement to acquire the dealership assets and real estate of Hennessy Automobile Companies (“Hennessy”), significantly expanding the Company’s presence in the Atlanta metropolitan market.

“Our cluster strategy has long focused on premium brands in attractive growth markets with high-revenue rooftops where we can leverage scale and expand margins,” said Daryl Kenningham, President and Chief Executive Officer of Group 1 Automotive. “Building on a strategy we have executed successfully across our largest markets, including Houston and Boston, this acquisition significantly expands our presence in the growing Atlanta market and creates new opportunities to enhance operational efficiency and deliver attractive, long-term returns. The Hennessy family has a tremendous reputation in Atlanta. We feel privileged to purchase this world class business. We thank the Hennessy family for trusting Group 1 with the transaction.”

The transaction includes 10 dealerships, a brand portfolio that contains key luxury and import brands, including Lexus, Jaguar/Land Rover and Porsche, and facilities containing 500 service bays staffed by approximately 280 technicians. It is expected to generate approximately $1.7 billion in annualized revenue and be immediately accretive to the Company’s earnings per share upon closing.

This transaction, together with the recent acquisitions of Stone Mountain Honda and Stone Mountain Toyota, will expand Group 1’s Atlanta presence from three to 15 dealerships, making the city the Company’s second largest market based on revenue and its ninth market in the U.S. with five or more stores.

Atlanta is a robust automotive market with strong fundamentals. The city is the sixth largest MSA1 and seventh largest DMA2 in the U.S., as well as the fastest-growing MSA and largest luxury vehicle market in the Southeast, with 21% luxury vehicle market share3. The city’s real GDP growth outpaced the national average growth rate by over 50% from 2014 to 20234 and the average household income within Hennessy’s markets specifically is approximately $150,000 per year5.

“For 62 years, our family company has been a cornerstone of the Atlanta automotive community, excelling in vehicle sales, servicing and leasing,” said Peter Hennessy. “Under Group 1’s stewardship, I know this strong legacy and deep commitment to Atlanta will continue. Group 1 shares our customer-focused philosophy, which will remain the foundation as they move our dealerships into the future.”

The Hennessy acquisition is valued at approximately $1.3 billion inclusive of blue sky, real estate and operating assets. Group 1 plans to finance the transaction with new debt, backstopped by a bridge commitment.

The transaction is expected to close by year-end 2026, subject to regulatory approvals, OEM approvals and customary closing conditions.

J.P. Morgan Securities LLC is acting as exclusive financial advisor, and Hill Ward Henderson and Vinson & Elkins LLP are serving as legal advisors, to Group 1. Kerrigan Advisors is acting as transaction advisor, and Holland and Knight is acting as legal advisor, to Hennessy Automobile Companies.
