Description of Business | Description of Business We are a leading global provider of high-end consulting and engineering services that focuses on water, environment, sustainable infrastructure, renewable energy and international development. We are a global company that is Leading with Science® to provide innovative solutions for our public and private clients. We typically begin at the earliest stage of a project by identifying technical solutions and developing execution plans tailored to our clients’ needs and resources. Our solutions may span the entire life cycle of high-end consulting and engineering projects and include applied science, data analysis, research, engineering, design, project management and operations and maintenance. We manage our business under two reportable segments. Our Government Services Group (“GSG”) reportable segment primarily includes activities with U.S. government clients (federal, state and local) and all activities with development agencies worldwide. Our Commercial/International Services Group (“CIG”) reportable segment primarily includes activities with U.S. commercial clients and international clients other than development agencies. Beginning in fiscal 2022, we aligned our operations to better serve our clients and markets, and created a new High Performance Buildings ("HPB") division in our CIG reportable segment. As a result, we transferred some related operations in our GSG reportable segment to our CIG reportable segment. Prior year amounts for reportable segments have been reclassified to conform to the current year presentation.
