Printing Money With Plastic Pipes
Advanced Drainage Systems proves that physical distribution networks and manufacturing scale create long-term advantages that can be as solid viral growth loops or network effects. ADS generates tech-company margins through old-school competitive barriers that took decades to build and can't be copied overnight.

Today, I'm looking at Advanced Drainage Systems (WMS). They are no stranger to the many farmers on this email list.
Quick context before we dive in:
Manufactures those green-striped plastic pipes you see at every construction site along with a lot of drain tile used in agriculture
Processes 540 million pounds of recycled plastic annually
Generates 32% EBITDA margins in what would appear to be a commodity product
Stock up 15x since 2014 IPO (vs 3x for S&P 500)
Why this matters for entrepreneurs
While AI has everyone captivated, ADS quietly built an empire through two decidedly old school advantages: scale and distribution.
Here's what's fascinating:
Scale still wins: Operating 60+ manufacturing plants gives them 1-2% cost advantage competitors can't match
Distribution dominates: 35 distribution centers create customer reach that no startup can replicate overnight
Infrastructure is surprisingly recurring: Every building, road, and parking lot needs their products
The uncomfortable truth for tech founders (myself included)
We live in a world obsessed with network effects, viral loops, and AI automation. But ADS proves that old-school competitive advantages still drive profitability:
Their "moat" isn't an algorithm - it's literally concrete plants you can't move
Customer acquisition often happens through relationships built over decades, not growth hacking
Switching costs can come from engineering specs just as easily as app stickiness
Being the largest player in their industry unlocks hard-to-replicate purchasing power
I was unable to pull what percentage of their revenue comes from agriculture but here's a fun tailwind for them: Most farmers in corn and soybean growing areas will tell you that drain tile is their highest ROI investment. I'm guessing that fact plays a contributing factor to their surprisingly high profit margins. And that's a lesson in itself!
With that, I'll see you tomorrow.

TL;DR
Advanced Drainage Systems (WMS) is America's largest plastic drainage pipe manufacturer, processing 540M pounds of recycled plastic annually
Revenue declined from $3.1B peak (2023) to $2.9B (2024) but maintained fortress-level 32% EBITDA margins
Dominates a $15B+ market through scale economies and distribution advantages across 64 plants and 35 distribution centers
Stock trades at $10.4B market cap despite recent earnings misses
Key takeaway: Scale and distribution are still powerful profit drivers even if the world his head-over-heels with tech and AI
The 30,000-Foot View
ADS manufactures the ubiquitous green-striped plastic pipes seen at construction sites nationwide. Their business model centers on four revenue streams: Pipe products (54%), Allied Products like fittings (23%), Infiltrator septic systems (16%), and International operations (7%).
Key stats:
$11.4B market cap
$2.9B trailing revenue
35%+ gross margins
$510M net income (FY2024)
5,000+ employees.
They're classified as construction materials but operate in water management.

The N.O.O.B. Nine — Competitive Powers
The Nerd Out on Business Nine is made up of Hamliton Helmer's famous "7 Powers" of competitive advantage (Scale Economies, Network Economies, Counter-Positioning, Switching Costs, Branding, Cornered Resource, and Process Power) combined with two of my own (Data Flywheel and Distribution Advantage).
Power | Score | Rationale |
---|---|---|
Branding | 4/5 | "America's Most Responsible Company" three years running creates B2B trust. Contractors know the green stripe means quality. |
Data Flywheel | 2/5 | Limited data advantages in pipe manufacturing. Some product performance tracking but not core to business model. |
Process Power | 4/5 | Proprietary N-12 pipe technology and integrated recycling processes create real barriers. New $65M R&D center deepens technical moat. |
Scale Economies | 5/5 | Operating 60+ plants with 540M pounds of recycled plastic gives ADS 1-2% margin advantage over competitors. Largest HDPE pipe manufacturer in North America by far. |
Switching Costs | 3/5 | Engineering specs lock in projects, but individual purchases have low switching friction. Contractor relationships provide moderate stickiness. |
Cornered Resource | 3/5 | Controls massive recycling operations but raw materials aren't exclusive. Strategic plant locations provide regional advantages. |
Network Economies | 2/5 | Pipes don't get more valuable with more users. Some distributor network benefits but not true network effects. |
Counter-Positioning | 4/5 | Positioned as climate-resilient water solutions provider while competitors sell commodity pipes. Sustainability angle disrupts traditional concrete/metal suppliers. |
Distribution Advantage | 5/5 | 40 distribution centers with thousands of relationships nationwide. Competitors can't match the reach or delivery speed. |
Average Score: 3.6/5 - ADS dominates through old-school competitive advantages (scale and distribution) rather than sexy tech moats
Memorable Marketing
ADS markets through data-driven infrastructure fear, positioning themselves as the solution. Key campaigns include:
Harris Poll Water Surveys (2023-2024): Commissioned national polls showing 60% of Americans worry about stormwater infrastructure. Strategy created third-party validation for infrastructure investment needs, generating significant media coverage positioning ADS as thought leader.
Columbus Blue Jackets Partnership (2024-2027): NHL sustainability partnership reinforces environmental credentials while building local brand awareness in headquarters market.
Engineering Center Launch (2024): $65M facility opening as marketing event provided tangible proof of innovation investment, creating premium positioning through "innovation theater."
Tactical takeaways:
Commission third-party research to validate market problems you solve
B2B companies need community presence for talent and credibility
Physical investments can serve as powerful marketing assets
AI Uses & Opportunities
Current AI adoption remains limited despite $10B scale. Manufacturing automation exists through FANUC robotics for safety and efficiency, but major AI initiatives are nascent.
Future opportunities:
Predictive maintenance across 60+ plants could save millions annually
Computer vision quality control to catch defects before shipping
IoT-enabled pipes creating recurring monitoring revenue streams
AI-optimized recycling to hit 1 billion pound target by 2032
Smart routing algorithms for distribution network optimization
Predictive infrastructure failure models for municipal sales
The company that develops "smart pipes" first captures the next decade of growth.
Bumps in the Road
Current challenges:
Overtime lawsuit alleging systematic wage violations through meal break interruptions
Q4 2025 earnings miss ($1.03 vs $1.08 expected EPS) triggered 6.35% stock drop
Revenue declined 6.4% in FY2024 as construction markets cooled
Raw material price volatility creates margin pressure
Industry risks:
Polybutylene pipe disasters of 1980s-90s haunt plastic pipe reputation
Climate change drives demand but extreme weather disrupts operations
International competition intensifying from Chinese manufacturers
Sustainability paradox of making plastic products, even recycled ones
Your Swipe File
Five lessons for entrepreneurs:
Turn costs into moats: ADS became North America's largest plastic recycler not for environmental kudos but because controlling recycled material supply creates 1-2% margin advantage. Vertically integrate where competitors can't or won't match.
Boring markets hide great businesses: Nobody dreams of making drainage pipes, which explains 32% EBITDA margins. Unsexy industries have less MBA competition and more pricing power from customer indifference.
Acquire capabilities, not just revenue: The $1.08B Infiltrator acquisition brought septic expertise generating 44% of revenue with less cyclicality. Buy businesses that strengthen your core offering.
Distribution beats disruption: In physical products, controlling the last mile matters more than revolutionary technology. ADS's 35 distribution centers create a nearly uncrossable moat regardless of pipe innovation.
Labor compliance isn't optional: ADS's overtime lawsuit shows operational excellence can't come at worker expense. One class-action suit erases years of efficiency gains and destroys cultural credibility.
