Exhibit 99.1

TO: GMS Customers

FROM: GMS on Behalf of Our Subsidiaries

SUBJECT: GMS Enters into Agreement with The Home Depot to Be Acquired by SRS Distribution

Dear Valued Customer,

I am reaching out with exciting news about the future of GMS. Today, we announced an agreement with The Home Depot® to be acquired by its specialty trade distribution subsidiary, SRS Distribution, as it continues to expand its offerings and capabilities to better serve professional contractors. You can read our press release here.

Joining forces with SRS and The Home Depot is an important step for GMS. Our team has earned the reputation of consistently executing with focus on our strategic pillars to expand our business and the products and solutions we provide to our customers. For both commercial and residential customers, we have grown our business by opening locations in existing and new areas across the U.S. and Canada – expanding our national reach to enhance our services while maintaining our local go-to-market focus. Throughout our evolution and expansion, we have never strayed from our commitment to be the best distributor in our end markets by consistently providing outstanding service and value for our customers by creating solutions that meet your needs.

The Home Depot is a company and brand that you likely know very well, and you may be aware that it acquired SRS last year. With the addition of GMS’ wallboard, ceilings, steel framing and complementary product categories, SRS will broaden its existing offerings for professional contractors. Both SRS and The Home Depot have great respect for the strong business we have built at GMS, and the new products and capabilities we can bring to their professional contractor customer offerings. Importantly, GMS, SRS and The Home Depot also share core values that include an entrepreneurial attitude, commitment to building strong relationships, delivering excellent service and believing you can never go wrong doing the right thing. We are confident that, together with SRS, we will be in an even stronger position to serve you for years to come.

I want to emphasize that today’s announcement is only the beginning, and nothing changes today at GMS or any of our subsidiary companies. Following close, JT, along with our senior leadership team, will continue to lead GMS as part of the SRS organization. We expect the transaction to close by the end of The Home Depot’s current fiscal year (January 31, 2026), subject to the receipt of required regulatory approvals and other customary closing conditions. Until that time, GMS will continue to operate separately and independently from SRS and The Home Depot. Put simply, it remains business as usual and there are no changes to how we work with you.

We look forward to continuing to do business with you and are confident that this transaction will allow us to better serve you well into the future.

We deeply value our relationship with you and appreciate your continued support.

Sincerely,

 

John C. Turner, Jr.

President & CEO

GMS Inc.
