ADS acquired Infiltrator Water Technologies via a reverse-triangular merger in which its subsidiary Ocean Sub, Inc. merged into Infiltrator, which became a wholly-owned ADS subsidiary. Signing and closing occurred simultaneously on July 31, 2019. Infiltrator is a leading national provider of plastic leach-field chambers and systems, septic tanks and accessories used primarily in residential onsite wastewater (septic) systems in the U.S. and Canada, and had been an ADS supplier and customer for over 15 years. ADS obtained a representation-and-warranty insurance policy as recourse for breaches of Infiltrator's reps and warranties. approximately $1.08 billion in cash (subject to post-closing adjustments).
ADS partly funded the purchase with a new credit agreement that replaced its prior facilities and in September 2019 raised roughly $293 million in a follow-on common-stock offering used mainly to repay borrowings.
ADS completed the acquisition of Jet Polymer Recycling, Inc., The Traylor Group, Inc. and certain assets of EAT Properties, L.L.C. (together, "Jet"), a privately owned recycling company in the southeastern United States. Prior to the deal, Jet was the largest supplier of recycled polypropylene for Infiltrator. The acquisition expands ADS's plastic-recycling capabilities to support future growth. $49.5 million (fair value of consideration transferred).
ADS completed its acquisition of Cultec, Inc., a family-owned technology leader in the stormwater and onsite septic wastewater industries. Cultec's injection-molded and thermoformed chambers are used for stormwater retention, detention and "first flush" underground storage, complementing ADS's existing StormTech chamber line. The deal added about 31 employees. $48.0 million (fair value of consideration transferred, after a working-capital adjustment).
The purchase price was later increased by $0.5 million to $48.0 million to reflect a measurement-period adjustment; goodwill of $11.1 million was recorded.
ADS's wholly-owned subsidiary Infiltrator Water Technologies, LLC completed the acquisition of Orenco Systems, Inc., a leading manufacturer of decentralized wastewater-management products for residential and non-residential end markets. Orenco's advanced treatment systems (including the AdvanTex AX line), effluent-treatment technologies and related accessories are used in onsite and decentralized commercial wastewater systems. ADS recorded a customer-relationships intangible of about $99 million and developed-technology intangible of about $42 million. $256.0 million gross (approximately $237.3 million net of $18.7 million cash acquired).
ADS recorded preliminary goodwill of $103.7 million attributable to expected operating efficiencies.
ADS completed the acquisition of the assets of River Valley Pipe, LLC, a privately owned pipe-manufacturing company located in the Midwest region of the United States. ADS recorded approximately $3.0 million of identifiable intangible assets (customer relationships and tradename). River Valley Pipe is reported within the Stormwater segment. approximately $18.8 million (preliminary fair value of consideration transferred).
ADS agreed to acquire the outstanding capital stock of certain indirect subsidiaries of Germany-based NORMA Group SE that comprise substantially all of its water-management business, known as National Diversified Sales (NDS), under a Master Share Purchase Agreement dated September 23, 2025; the all-cash deal closed February 2, 2026. NDS adds residential water-management, access-box and irrigation solutions and generated about $313 million of trailing-twelve-month revenue (roughly 90% in the U.S.). Certain NDS international entities were classified as held for sale on acquisition. ADS obtained a warranty-and-indemnity insurance policy as recourse. approximately $1.0 billion (purchase price of $984.9 million; ~$972.5 million net of cash acquired; ~$875 million adjusted for present value of expected tax benefits).
The acquisition of NDS marks another important milestone in ADS' journey as it accelerates our strategy to diversify and increase the mix of highly profitable Allied and Infiltrator products that enhance resiliency, supports profitable growth, and allows ADS to pursue water management projects across a broader set of applications.Scott Barbour — Chief Executive Officer and President, Advanced Drainage Systems
