Baron Discovery Fund Randy Gwirtzman | “During the quarter, we reinitiated a position in Advanced Drainage Systems, Inc. (ADS), the leading U.S. manufacturer of stormwater and onsite wastewater management products. The company offers a comprehensive suite of pipes, drainage structures, storage chambers, and water treatment systems designed to manage stormwater from the moment it hits the ground until it is returned cleanly to the environment. We view ADS as a high quality, competitively differentiated business. It is the only national player of scale in an otherwise fragmented market and is roughly 10 to 15 times larger than its next closest competitors. Its manufacturing and logistics footprint is unmatched, spanning more than 60 plants and a company-owned fleet of roughly 600 trucks and 1,100 trailers that enables delivery of bulky products directly to jobsites. Its vertically integrated recycling operations, which supply roughly half of its raw materials at a discount to virgin resin, make it the lowest cost producer in the space. ADS operates in an industry that is currently benefitting from both secular and cyclical tailwinds. The company estimates the combined stormwater and onsite wastewater market at roughly $16 billion today, of which it holds only a high teens share, leaving ample room to grow. Several secular tailwinds are working in its favor, most notably the rising frequency and intensity of storms and the aging, undersized infrastructure across much of the country, both of which are driving greater investment into stormwater management systems. On the wastewater side, only about 25% of U.S. homes currently have an onsite septic system versus roughly a third of new homes being built, so adoption should rise naturally over time. Underpinning all of this is the steady, multi-decade conversion from legacy concrete pipe and tanks to plastic, which is cheaper, lighter, and both faster and less labor-intensive to install. From a cyclical standpoint, both residential and non-residential new construction markets are potentially at cyclical lows following several years of muted activity. We see a compelling, multi-year growth opportunity ahead for ADS. Management outlined a credible path to grow revenue organically at a rate greater than 8% through 2030, and at greater than 10% including acquisitions, drawing on a strong track record of using M&A as a growth lever. We also expect margins to expand over time, supported by operating leverage as residential and non-residential new construction markets eventually recover, along with ongoing new product introductions and favorable price/cost realization. Finally, we believe the valuation is attractive today, with shares trading at a below-average multiple of roughly 12 times fiscal 2027 EBITDA on what should prove to be near-bottom-of-the-cycle earnings.” | NEUTRAL | Q2 2026 Aug 5, 2026 | View Pitch |
