SITEONE LANDSCAPE SUPPLY ANNOUNCES THE RETIREMENT

ROSWELL, GA – MARCH 31, 2026 – SiteOne®

Landscape Supply, Inc. (the “Company”) (NYSE: SITE) announced today that Scott Salmon will retire from his role as Executive

Vice President of Strategy and Development on March 31, 2026. In connection with Mr. Salmon’s retirement, the Company has also announced

Executive Leadership Team, also effective March 31, 2026. Following the transition, Mr. Salmon will remain with the Company in a limited

capacity for a duration of time.

“Since joining SiteOne in 2019, Scott has played an important

role during a key period of our growth, leading our acquisition efforts and supporting the company’s strategy through disciplined

expansion, integration, and long-term value creation initiatives,” said Doug Black, Chairman and CEO of SiteOne. “During his

tenure, Scott helped add over 70 companies to SiteOne while significantly improving our integration and onboarding of these businesses.

We appreciate Scott’s many contributions to the company and I want to personally thank him for his years of service.”

Marcone Supply, and most recently Alloy Roofing. He has a degree in Finance and Accounting from the University of North Carolina at Charlotte

and an MBA from the Wake Forest University School of Business.

“Daniel has worked closely with Scott over several years and
