Mueller earnings grow more slowly than revenue
Mueller’s third-quarter earnings announcement showed diluted earnings per share of $1.00, compared with $0.94 a year earlier. Both periods reflect the two-for-one stock split that took effect on June 30, 2026.
Revenue increased to $1,418.6 million from $1,077.8 million. Mueller said unit volumes grew across most businesses, while price adjustments tied to higher material costs also contributed. COMEX copper averaged $6.48 per pound during the quarter, up 34.2% from the prior-year period.
Operating income rose more modestly, to $281.6 million from $276.1 million. That left the operating margin at approximately 19.8%, down from 25.6%, calculated from the reported figures. The results included $9.4 million in purchase-accounting charges related to recent acquisitions.

Commercial demand offsets residential weakness
Chief Executive Officer Greg Christopher said demand remained healthy and backlogs increased in each of Mueller’s three segments, largely propelled by U.S. data-center expansions and other commercial building activity. He described the quarter as the ninth consecutive period of year-over-year earnings growth.
That strength contrasted with a prolonged decline in residential construction. Christopher credited the company’s response to changing demand and product mix, as well as its management of pricing relative to cost increases.
Piping Systems remained Mueller’s largest segment by sales and operating income. All three segments reported higher sales and operating income than in the third quarter of 2025.
Cash generation supports buybacks and manufacturing investment
Quarterly operating cash flow of $337 million brought cash and short-term investments to $1.48 billion at quarter-end. Mueller reported a current ratio of 4.4 to 1, measuring current assets against current liabilities.
The company bought back 3.2 million shares for $201.9 million during the quarter, bringing year-to-date repurchases to 4.5 million shares. Dividends per share increased to $0.175 from $0.125 on a split-adjusted basis.
Looking toward the end of 2026 and beyond, Christopher outlined continued investment in North American manufacturing to reduce costs and reshore production. Management also plans to broaden product offerings and distribution capabilities. He said these initiatives would position Mueller for an eventual residential-construction recovery, without specifying when that recovery would occur.
Conclusion
Mueller’s quarter combined higher earnings and strong cash generation with a narrower operating margin. The next operational focus is execution of its announced manufacturing and distribution initiatives, while residential construction remains a weak market rather than a confirmed source of recovery.
