Water Infrastructure Meets Data Centers: Mueller’s New Growth Vector, Tariff Refunds Bolster Margins, but Weak Housing Clouds Guidance
A record third quarter and a third consecutive EBITDA guide raise arrive as the stock sags, with investors weighing the novelty of data-center water opportunities against near-term residential and tariff headwinds.

Record Quarter, Subdued Market
Mueller Water Products delivered one of its strongest quarters yet: net sales grew 4.1% to $395.9 million, adjusted EBITDA jumped 24.3% to a record $107.4 million, and adjusted diluted EPS climbed 47.1%. Management again raised full-year adjusted EBITDA guidance, now $367–$372 million, the third consecutive raise.Yet the market has not rewarded the stock. Over the 90 trading days through August 21, MWA fell roughly 16% from its April high of $30.37, as investors have priced in the softer fourth-quarter tone: sales guidance was narrowed to 2.8%–3.5% growth, and the company explicitly called out weaker residential construction and lapping tariff-related pricing from last year. The strong quarter was real, but the forward-looking signals remain mixed.We achieved quarterly records for net sales, adjusted EBITDA and adjusted net income per diluted share.
Tariff Refund Tailwind Is a One-Time Boost
The quarter’s margin expansion was significantly aided by IEEPA tariff refunds. CFO Melissa Rasmussen noted in her prepared remarks, “the International Emergency Economic Powers Act tariff refunds received during the quarter helped offset a portion of those impacts.” — Melissa Rasmussen, CFO · 2026-08-06In Q&A, she quantified a 150-basis-point adjusted gross margin benefit from the refunds, split roughly evenly between the two segments. That is a welcome cash infusion, but it is not recurring—management explicitly stated they expect no further refunds. Furthermore, higher Section 232 tariffs are now pressuring the Krausz product line. Tariff refunds dominated the company’s own keyword trajectory this quarter, and the global market mirrored the theme with IEEPA refund among the top momentum keywords. The tension is that the prior quarter’s margin tailwind is now a difficult comparison, even as the company’s pricing power and cost discipline keep adjusted EBITDA guidance rising.Data Centers: A Genuine New Frontier
The most notable new theme this quarter is the data-center water infrastructure opportunity. In response to a question about specialty valves, CEO Paul McAndrew said,This is a clear strategic pivot—previous calls were almost entirely focused on municipal repair and replacement, with Residential construction as the dominant cyclical variable. The data centers angle dovetails with the broader AI infrastructure buildout, and industrial water is a natural extension for a company whose products sit in the ground. Still, management was careful to size the opportunity: “It's relatively small in the overall size of the business for us,” Paul later added. It is early but has the hallmarks of a durable growth driver.Industrial water, although a small category for us, has been one of our fastest-growing categories as we kind of not just think about the potable water or the infrastructure water around data centers, we're also seeing a step increase then of our ability to get specialty valves into industrial water for data centers as well.
