EcoVadis anually evaluates more than 150,000 companies across 150 countries measuring performance in four key areas:
HMS had a Gold Rating as a medium-sized company before, but this is the first time the company is rated Gold as large-sized company.

"This result validates that HMS has successfully embedded sustainability into its business processes despite significant growth and acquisitions. Sustainability is not a standalone initiative at HMS, it is integrated into how we operate across divisions, functions, and teams. Our goal is to maintain our Gold rating through 2030. But sustainability is a continuous process, and we still have things to improve. We aim even higher"
