Mueller Industries, Inc. Reports Third Quarter 2026 Earnings

COLLIERVILLE, Tenn., October 20, 2026 -- Mueller Industries, Inc. (NYSE: MLI) announces results for the third quarter of 2026. Comparisons are to the third quarter of 2025.

•Net Sales increased to $1.42 billion versus $1.08 billion.

•Net Income increased to $221.2 million versus $208.1 million.

•Operating Income increased to $281.6 million versus $276.1 million.

•Diluted EPS* increased to $1.00 versus $0.94.

•Dividends per share* increased to $.175 versus $.125.

* Diluted EPS and dividends per share have been adjusted to reflect the two-for-one stock split that took effect on 6/30/2026.

Third Quarter Financial and Operating Highlights:

•COMEX copper averaged $6.48 per pound during the quarter, a 34.2 percent increase over the prior year period.

•Unit volume growth across most of our businesses, combined with price adjustments related to the rise in material costs, contributed to the increase in net sales.

•The results include $9.4 million in charges related to purchase accounting for recent acquisitions.

•Net cash generated from operations was $337.0 million, raising our cash and short-term investments at quarter end to $1.48 billion.

•During the quarter, we purchased 3.2 million shares of our common stock for a total of $201.9 million. Year-to-date, we have purchased 4.5 million shares.

• Our current ratio remains strong at 4.4 to 1.

Regarding the results, Greg Christopher, Mueller’s CEO said, “For the ninth consecutive quarter, we delivered year over year earnings growth driven by stronger performance across all three of our business segments. Throughout the quarter, demand remained healthy and backlogs grew in each segment, largely propelled by U.S. data center expansions and other commercial building activities. These results are particularly noteworthy given the protracted decline in the residential construction market. Our team has done an excellent job adjusting to shifts in demand and mix, as well as managing price relative to cost escalation.”

Regarding the outlook, he added “As we approach the finish line for 2026 and look ahead, we remain optimistic as we execute on our key strategic priorities. These include investments in our North American manufacturing operations to reduce costs and reshore production to support shifting demand, along with initiatives to increase our product offerings and expand distribution capabilities across multiple business

segments. These actions will keep us well-positioned to capitalize on opportunities when residential building construction recovers in the U.S. and global economic conditions improve.”

Mueller Industries, Inc. (NYSE: MLI) is an industrial corporation whose holdings manufacture vital goods for important markets such as air, water, oil and gas distribution; climate comfort; food preservation; electrical transmission; medical; aerospace; and automotive. It includes a network of companies and brands throughout North America, Europe, Asia, and the Middle East.
