HILLIARD, Ohio — Advanced Drainage Systems, Inc. (NYSE: WMS) (“ADS” or the “Company”), a leading provider of innovative water management solutions in the stormwater and onsite wastewater industries, announced it has been named to TIME’s 2026 list of the World’s Most Impactful Companies. This annual recognition highlights organizations that are making extraordinary contributions to addressing global challenges through innovation, sustainability and measurable impact.

ADS was recognized for its leadership in advancing sustainable infrastructure, expanding circular manufacturing practices and delivering solutions that protect and manage the world’s most critical resource: water.

“Customers today want partners who can help them solve complex water challenges in a sustainable way,” said Brian King, EVP, Marketing, Project Management and Sustainability at ADS. “Our recognition by TIME reflects how ADS delivers on that expectation through innovation, scale and an unwavering focus on long-term performance.”

ADS leads the industry in water management innovation. Central to this leadership is the Company’s 110,000 square-foot Engineering and Technology Center – the largest and most advanced stormwater research facility in the world. It features a 90,000 gallon, closed-loop recyclable water system that replicates real-world storm conditions, a hydraulics lab that supports water separation, traditional filtration and low-impact development filtration, a Materials Science Lab dedicated to structural performance analysis and recycled plastics testing, and an Advanced Technology Lab equipped with 3D printing, prototyping and small-scale sample pipe production. Together, these capabilities accelerate product development and validation, enabling ADS to deliver solutions that help customers meet evolving regulatory requirements, mitigate flooding risk, optimize land use, and improve water quality — creating measurable environmental and economic value.

A key driver of ADS’ impact is its commitment to circularity. As one of the largest plastic recyclers in North America, the Company diverts over half a billion pounds of plastic from landfills annually and transforms it into high-performance drainage products. This approach not only reduces environmental impact but also provides customers with durable, cost-effective solutions that meet evolving sustainability goals.
