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.”

•Adjusting for the $36.3 million insurance gain ($28.1 million net of tax) recognized in the second quarter of 2025, we delivered a 15.7 percent increase in operating income.

•Unit volume growth in each of our three reporting segments, combined with price increases related to the rise in material costs, contributed to the overall increase in net sales.

Regarding the results and outlook for the business, Greg Christopher, Mueller’s CEO said, “We delivered consistent year over year earnings growth and executed at a high level. Business demand continues to strengthen in our commercial, industrial and electrical markets. Backlogs are strong, and we are carrying out our 2030 strategic plan initiatives with a high sense of urgency. During the quarter, we completed two acquisitions in our core metals businesses — Bison Metals Technologies on March 30, 2026, and Chicago Extruded Metals on June 12, 2026. With Bison already having delivered a record second quarter, we expect both to meaningfully contribute in the near term.

We are optimistic that the U.S. residential construction markets will eventually improve, and look forward to a resolution of the conflict in Iran, leading to lower energy costs and reduced inflationary pressures. As such, we are anticipating continued strength in our business.”
