Boyd Group Services Inc. Announces Closing of

C$525 Million Senior Unsecured Note Offering

Not for distribution to U.S. newswire services or for dissemination in the United States

Winnipeg, Manitoba – November 6, 2025 – Boyd Group Services Inc. (TSX: BYD) (NYSE: BGSI) (“BGSI” or the “Company”) today announced that it has successfully closed its previously announced private placement offering (the “Offering”) of C$525 million principal amount of senior unsecured notes due 2030 of the Company (the “Notes”). As previously stated, the Company intends to use the net proceeds of the Offering, together with proceeds from the Company’s previously announced equity offering, to partially fund the purchase price for the acquisition of Joe Hudson’s Collision Center, a provider of automotive collision repair services (the “Acquisition”), as previously announced on October 29, 2025, pursuant to a definitive equity purchase agreement dated October 29, 2025 (the “Purchase Agreement”). In connection with the closing of the Offering and the closing of the Company’s US$897 million common share offering (the “Equity Offering”), which closed on November 4, 2025, the bridge facility commitments obtained by the Company as a source of interim financing for the Acquisition will be fully cancelled and replaced with the aggregate net proceeds of the Equity Offering and the Offering. The closing of the Acquisition is expected to occur in the fourth quarter of 2025, subject to customary closing conditions and regulatory requirements.

If the closing of the Acquisition has not occurred on or prior to 5:00 p.m. (Toronto time) on April 29, 2026 (or such later date as permitted in accordance with the Purchase Agreement), or if, prior to such time, the Purchase Agreement is terminated in accordance with its terms or BGSI issues a press release announcing, or notifies the trustee for the Notes, that it does not intend to proceed with the Acquisition, as further described in the terms of the Notes, the Notes will be subject to a special mandatory redemption at a price equal to 100 percent of the principal amount of the Notes, plus accrued and unpaid interest, if any, to the date of such special mandatory redemption.

The offering was underwritten by a syndicate of underwriters led by National Bank Capital Markets, TD Securities and RBC Capital Markets, as joint active bookrunners, and by CIBC Capital Markets, as joint passive bookrunner.

The Notes were offered for sale in Canada on a private placement basis and to qualified institutional buyers pursuant to Rule 144A under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”) in the United States. The Notes have not been and will not be registered under the U.S. Securities Act, and may not be offered, sold or delivered, directly or indirectly, in the United States absent registration or an applicable exemption from the registration requirements of the U.S. Securities Act. This news release shall not constitute an offer to sell or the solicitation

of an offer to buy the Notes in the United States, nor shall there be an offer, solicitation or sale of the Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful.
