Management Comments

• Scott Barbour, CEO and President of ADS, stated: 'ADS continues to evolve from a pipe manufacturing company to an enterprise providing a wide range of stormwater and onsite wastewater solutions, with leading manufacturing, logistics and design services.'
• Mr. Barbour highlighted: '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.'
• Mr. Barbour also noted: 'Our disciplined capital allocation framework and strong balance sheet provide us the flexibility to act when opportunities like this arise, while continuing to invest in our business and return capital to shareholders.'
• He expressed confidence: 'Through our investment in NDS and applying ADS proven operating model and integration expertise, we expect to drive enhanced profitability and realize significant synergies as a combined entity.'
• Mr. Barbour concluded: 'The combination of NDS well-regarded brand and product portfolio in residential stormwater and irrigation with ADS complementary capabilities, operating discipline, and customer reach, will enhance the solutions we deliver to our customers.'

Industry Context

This acquisition positions Advanced Drainage Systems to further capitalize on the growing demand for comprehensive water management solutions, driven by increasing urbanization, climate change impacts (e.g., stormwater runoff), and the need for efficient irrigation. By integrating NDS's residential stormwater, landscape irrigation, and flow management expertise, ADS diversifies its product portfolio beyond traditional pipe manufacturing, aligning with a broader industry trend towards integrated, full-scale solutions. The move into the $1.5 billion landscape irrigation segment and increased exposure to the Residential Repair & Remodel market provides ADS with access to resilient, high-growth areas, potentially mitigating some of the cyclicality associated with new construction.

Comparison to Industry Standards

• ADS's proforma net debt of 1.6x at close is within its target range of 1.0-2.0x, indicating a disciplined approach to leverage compared to industry peers who might take on higher debt for growth.
• The transaction value, net of estimated tax benefits, represents a multiple of ~10x NDS Adjusted EBITDA (TTM June 2025), inclusive of expected run-rate cost synergies. This multiple suggests a reasonable valuation for a market leader with strong growth potential and synergy opportunities, comparable to valuations seen in strategic acquisitions within the specialized industrial and water infrastructure sectors.
• ADS highlights its 'proven integration capabilities and operational discipline,' referencing the successful acquisition of Infiltrator Water Technologies in 2019, which doubled Infiltrator's revenue under ADS ownership and yielded approximately $60 million in synergies. This track record sets a high internal benchmark for successful integration and value creation compared to industry averages for M&A success rates.
