Advanced Drainage Systems, Inc. provides an in-depth look at its business in its latest annual report, highlighting its role as a leading manufacturer of stormwater and onsite wastewater management solutions. The company now operates through two reportable segments, Stormwater and Wastewater, following a realignment that reflects its broader product mix and the impact of acquisitions.

Key risks discussed include resin price and supply volatility, construction and agriculture cyclicality, customer concentration, climate and regulatory developments, cybersecurity, manufacturing disruptions and labor availability.
