Advanced Drainage Systems, Inc. (NYSE:WMS) is one of the best water infrastructure stocks to buy as AI data centers strain resources. On May 21, 2026, the company reported fourth-quarter fiscal 2026 net sales of $676.8 million, up 9.9% year over year, with stormwater sales rising 11.7% to $534.7 million. Management said the company remains focused on gaining share in growing construction segments, specifically naming data centers as one of the markets supporting its long-term strategy.
ADS is not a liquid-cooling supplier, but data center campuses still require major site-water infrastructure before they can operate, including stormwater drainage, runoff control, underground conveyance, wastewater systems, and rainwater management. The company’s February 2026 acquisition of National Diversified Sales also expanded its water management offering and added $48.8 million of stormwater revenue in the fourth quarter. For fiscal 2026, ADS generated $3.05 billion in net sales, up 5%, while wastewater sales increased 13% to $653.0 million. Its fiscal 2027 outlook calls for net sales of $3.35 billion to $3.55 billion, suggesting continued demand for stormwater and wastewater infrastructure.

Four leading AI models discuss this article
"ADS's upside rests on a sustained infrastructure capex cycle and ongoing data-center site-water demand; without that, the stock's upside multiple compression and margin risks rise."
ADS's Q4 results show resilience in stormwater and wastewater, with 9.9% sales growth and a 5% FY2026 top-line rise, and management signaling data centers as a longer-term growth pillar. The notion that data-center campuses directly fund site-water infrastructure is plausible: greenfield builds require drainage, runoff controls, and wastewater networks, and ADS has the product lineup plus no exposure to direct liquid cooling. The risk is macro: infrastructure budgets, rate pressures, and input costs could slow capex; the 2027 sales guide ($3.35–$3.55B) assumes a continued upcycle in U.S. water programs and private projects. Execution risk and integration (National Diversified Sales) also loom as potential headwinds.
If a data-center capex cycle slows or municipal budgets tighten, ADS’s stormwater/wastewater volumes could stall, and margins could disappoint if input costs rise or if the NDS acquisition underperforms.
"WMS is a high-quality infrastructure play, but its current valuation leaves zero room for error if commercial construction cycles soften."
WMS is currently trading at roughly 22x forward earnings, a premium that assumes consistent mid-to-high single-digit revenue growth. The data center tailwind is real; these massive campuses require massive site-prep for stormwater management to prevent flooding and meet strict environmental compliance. However, the market is over-indexing on the AI hype while ignoring the cyclicality of the broader construction market. With residential and non-residential construction still facing headwinds from elevated interest rates and tighter credit conditions, WMS's reliance on site-prep makes it highly sensitive to project delays. If the data center boom hits a regulatory or power-grid bottleneck, the valuation premium will evaporate quickly.
If WMS successfully pivots its product mix toward high-margin engineered solutions and secures long-term master service agreements with hyperscalers, the stock could justify a 25x+ multiple as a 'utility-like' infrastructure play.
"WMS benefits from DC infrastructure tailwinds, but the company has not quantified DC exposure as a percentage of revenue, making it impossible to assess whether this is a structural growth driver or a cyclical bump."
WMS reported solid 9.9% top-line growth with stormwater up 11.7%, and management explicitly flagged data centers as a long-term driver. The National Diversified Sales acquisition ($48.8M stormwater revenue in Q4) suggests management is actively positioning for this trend. FY2027 guidance of $3.35–$3.55B implies 10–16% growth. However, the article conflates correlation with causation: data centers need site drainage, yes, but WMS doesn't disclose what percentage of revenue actually flows from DC construction. Stormwater is a fragmented, commoditized market with thin margins. The real risk is whether WMS can sustain 11%+ stormwater growth if DC capex cycles normalize or if competitors (Forterra, Quanex) capture share.
Data center construction is front-loaded with site prep but back-loaded on operational water needs; WMS may see a revenue cliff once the DC buildout wave plateaus. The company's 5% FY2026 growth and reliance on M&A (National Diversified) to hit guidance suggests organic momentum is weaker than headline numbers imply.
"WMS growth figures reflect general construction activity more than a quantifiable data-center catalyst."
The article positions WMS as a beneficiary of AI data-center buildouts via stormwater and wastewater infrastructure, citing 9.9% Q4 sales growth and a $3.05B fiscal 2026 total with 5% YoY gains. Yet it provides no breakdown of data-center revenue contribution, and the 11.7% stormwater increase aligns with broader construction rather than proving a distinct AI-driven surge. The National Diversified Sales acquisition added just $48.8M in Q4, while the fiscal 2027 outlook of $3.35-3.55B implies only mid-single-digit expansion. General site-work demand may support results, but the piece overstates specificity to hyperscale campuses.
Even modest current exposure could scale rapidly if data-center permitting accelerates through 2027-2028, turning incremental stormwater work into a durable high-margin stream that the modest headline growth numbers understate.
"WMS's valuation relies on a durable, recurring DC-related revenue stream that is not yet proven; cyclical capex and uncertain DC revenue mix threaten multiple-contraction if the hype fades."
Gemini overweights the data-center tailwind as a durable driver; the real risk is cycle sensitivity and lack of DC-revenue disclosure. Even with MSAs, site-prep work is highly capex-sensitive and front-loaded; if DC capex slows or permitting bottlenecks bite, WMS's stormwater/wastewater momentum could stall and margins stay thin in a commoditized market. The 22x forward multiple already embeds a strong AI/tech hype premium that could compress quickly if visibility fades.
"The shift toward high-margin engineered water solutions allows WMS to decouple from commoditized construction cycles and justify its current valuation."
Claude and Grok are right to question the 'AI-infrastructure' narrative, but they miss the real leverage: margin expansion through product mix, not just volume. WMS is shifting from commoditized corrugated pipe to high-margin, engineered water-management systems. The NDS acquisition isn't just about revenue; it’s about selling complex solutions that hyperscalers prioritize to meet strict ESG-related stormwater mandates. The valuation isn't just hype; it's a bet on WMS capturing the 'premium' tier of site-development spend.
"Margin expansion requires disclosed proof; absence of margin-rate commentary in earnings suggests the mix shift either hasn't happened yet or isn't material enough to highlight."
Gemini's margin-mix thesis is plausible but unverified. WMS hasn't disclosed what percentage of stormwater revenue is 'engineered solutions' vs. commoditized pipe, or what gross margins those segments carry. If NDS was acquired at a premium for high-margin ESG compliance work, that should show up in reported margins—yet Q4 gross margins aren't flagged as expanding. Until WMS breaks out segment profitability, the 'premium tier' story remains speculative. Valuation compression risk if this mix shift doesn't materialize.
"No Q4 margin lift after NDS acquisition undercuts the engineered-solutions premium story."
Gemini's margin-mix thesis assumes NDS will lift profitability via ESG-engineered systems, yet Q4 gross margins showed no expansion even after adding that revenue. Without segment-level disclosure on engineered versus pipe margins, the shift remains unproven and the 22x multiple continues to price in unverified premium pricing power. If site-prep stays commoditized, any data-center volume gains will not protect against multiple compression.
The panelists have mixed views on WMS's prospects, with concerns about the cyclical nature of construction, lack of data center revenue disclosure, and thin margins in the stormwater market. However, they also acknowledge the potential for margin expansion through product mix and the acquisition of National Diversified Sales.
