Group 1 Automotive Closes $1,250.0 Million Offering of Senior Notes

HOUSTON, TX, September 22, 2026 - Group 1 Automotive, Inc. (NYSE: GPI) ("Group 1" or the "Company"), a Fortune 250 automotive retailer with 249 dealerships located in the U.S. and U.K., today announced the closing of its previously announced private placement of $625.0 million in aggregate principal amount of its 6.250% senior unsecured notes due 2032 (the "2032 Notes") and $625.0 million in aggregate principal amount of its 6.625% senior unsecured notes due 2035 (the "2035 Notes" and, together with the 2032 Notes, the "Notes").

The Company intends to use the net proceeds of the offering, together with cash on hand, to fund the purchase price for its previously announced acquisition of certain dealership assets and related real estate from Hennessy Automobile Companies, Inc. and certain of its affiliates (the "Hennessy Acquisition") and to pay related fees and expenses. Pending the closing of the Hennessy Acquisition, the Company intends to use the net proceeds to repay a portion of the outstanding borrowings under the acquisition line under its revolving credit facility, which the Company expects to reborrow at the closing of the Hennessy Acquisition to fund a portion of the purchase price.

"We are pleased to have closed this offering, which provides us with long-dated capital to fund the Hennessy Acquisition on attractive terms," said Daniel McHenry, the Company's Chief Financial Officer and CEO of UK Operations. "I want to thank the investors who participated for their confidence in Group 1, as well as our financing partners and the teams across our organization whose work made this transaction possible."

If the Hennessy Acquisition is not consummated on or prior to the later of (x) January 6, 2027 (the "Outside Date") and (y) such date to which the Outside Date under the purchase agreement relating to the Hennessy Acquisition may be extended in accordance with the terms thereof (such later date, the "Special Mandatory Redemption Outside Date"), or upon the occurrence of certain other events, including the termination of the purchase agreement related to the Hennessy Acquisition prior to the Special Mandatory Redemption Outside Date, the Company will be required to redeem all of the 2032 Notes then outstanding at a redemption price equal to 100% of the initial issue price thereof, plus accrued and unpaid interest, if any, from the issue date to, but excluding, the redemption date (the "Special Mandatory Redemption"). In that case, the Company intends to use the net proceeds of the offering that are not used to fund the Special Mandatory Redemption to repay borrowings under the Company's revolving credit facility and for general corporate purposes.

The Notes have not been, and will not be, registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws, and thus, the Notes may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The Notes were offered and sold to persons reasonably believed to be qualified institutional buyers in an offering exempt from registration pursuant to Rule 144A under the Securities Act and to non-U.S. persons outside of the United States in compliance with Regulation S under the Securities Act. This announcement shall not constitute an offer to sell or a solicitation of an offer to buy any of these Notes or any security, and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offering, solicitation or sale would be unlawful.
