CHICAGO--(BUSINESS WIRE)-- PSP Capital, a global private investment firm founded by its Chairman, Penny Pritzker, announced that it has entered into a definitive agreement to sell StormTrap, a leading provider of stormwater management systems and water quality solutions, to Advanced Drainage Systems, Inc. (NYSE: WMS) ("ADS"), a global leader in innovative water management solutions.

The transaction, which was announced by ADS, is expected to close in the coming months, subject to customary regulatory approvals. The transaction values StormTrap at approximately $530 million.

PSP Capital invested in StormTrap in March 2022, partnering with the company's management team to accelerate growth, expand its product portfolio, strengthen its research and development capabilities, and further solidify its successful position in the rapidly growing stormwater infrastructure market.

During PSP Capital's ownership, StormTrap significantly expanded its operations and market reach. The company added more than 60 employees, constructed a state-of-the-art research and testing facility, launched multiple innovative water quality products, completed a strategic tuck-in acquisition, and more than doubled revenue and earnings. Today, StormTrap is recognized as a leading provider of highly engineered stormwater detention, infiltration, treatment, and water harvesting solutions serving municipalities, developers, engineers, and contractors across North America.

StormTrap's growth was supported by powerful long-term trends, including increased development density, aging infrastructure, stricter stormwater regulations, rising land values, and the growing need for resilient infrastructure in the face of more frequent extreme weather events.

"We are so fortunate to have partnered with CEO Nate Olds and the outstanding StormTrap leadership team,” said Don Traubert, Managing Director with PSP Capital. “They have a deep passion for stormwater management that resonated from our first meeting. Over the past 5 years, StormTrap executed a thoughtful strategic growth plan that has reinforced its position as an industry leader and innovator. We are excited to see the business continue its strong trajectory under ADS' ownership."

Nate Olds, CEO of StormTrap, said, "From our first interaction, the PSP Capital team demonstrated an understanding of our business and embraced our long-term vision for growth. Together we invested in our people and organization, driving innovation and bolstering our leading market position. Our partnership with PSP Capital was highly collaborative and impactful, and we are well-positioned for this next chapter.”

The transaction represents a successful outcome for StormTrap, its employees, customers, and stakeholders and reinforces PSP Capital's commitment to partnering with exceptional management teams to build market-leading businesses through long-term investment and strategic support.
