What Mueller Industries does

Mueller Industries, Inc. (NYSE: MLI) is a U.S.-headquartered industrial manufacturer founded in 1917 and based in Collierville, Tennessee. The company specializes in copper and copper alloy manufacturing and also produces goods from aluminum, steel, and plastics, operating through three reportable segments: Piping Systems (copper tube, fittings, valves, line sets for potable water, HVACR, medical gas, and data center cooling), Climate Products (heat exchangers, sight-glasses, flexible duct, complex manifolds, pressure vessels, refrigeration components), and Industrial Metals (copper and brass rod, forgings, extrusions, precision-machined components, and large-diameter conductors for OEM manufacturers in appliance, automotive, defense, aerospace, medical, energy, and telecommunications).

Mueller is the only vertically integrated manufacturer of copper tube and fittings, and brass rod and forgings in North America, running a decentralized portfolio of more than 20 subsidiaries and joint-venture interests — including Mueller Brass, MG Machining, Conex Cable, Westermeyer Industries, Precision Tube, Mueller Impacts, Mueller Forgings, Turbotec, Linesets, ATCO Flexible Duct, Mueller Streamline, Kessler Sales and Distribution, Elkhart Products, BK Products, Bison Metals Technologies (acquired March 2026), Mueller Europe (UK), Mueller Middle East (Bahrain JV with Mumtalakat and Cayan Ventures), and a joint interest in Tecumseh Products (with Atlas Holdings). Manufacturing and distribution operations span the United States, Canada, Mexico, the United Kingdom, South Korea, China, and Bahrain, with end markets reached across more than a dozen countries.

The business model is fundamentally B2B hardware sales. Revenue is generated through three streams — Piping Systems Products, Industrial Metals Products, and Climate Products — sold via a hybrid go-to-market that combines wholesale and retail distributor networks (notably Kessler Sales and Howell Metal), company-owned sales and distribution support locations (Collierville TN, West Palm Beach FL, Covington TN, University Park IL, Ennis TX, Fulton MS, Jacksonville FL, Ontario CA, Sanger CA), direct OEM sales for precision components and conductors, and regional manufacturing-for-local-markets in Europe and the Middle East. Pricing is negotiated directly with distributors, OEMs, and end customers and is not publicly disclosed. FY2025 revenue reached $4.2 billion (up 10.5% YoY) with a record $765.2 million in net income and $958.5 million in operating income; Q1 2026 revenue rose 19% to $1.19 billion with record EPS of $2.16, supported by a $1.38 billion cash balance, no long-term debt, 25%+ ROE, and 23 consecutive years of dividend payments.

Direct peers

• Wieland Group: European-headquartered manufacturer of copper and copper alloy semi-finished products including tubes, strips, rods, and wires. Wieland is the closest global comparable to Mueller's copper tube and fittings business, serving plumbing, HVACR, automotive, and electronics end markets with similar product breadth.
• Materion Corporation: U.S. specialty metals manufacturer producing precision-engineered materials including beryllium, copper, and copper alloy products serving industrial, aerospace, defense, and electronics markets. Materion's specialty copper products directly overlap with Mueller's Industrial Metals segment.
• KME Group: European copper products manufacturer producing copper and copper alloy tubes, bars, and rods for plumbing, HVAC, and industrial applications. KME directly competes with Mueller Industries in copper tube markets across Europe and select global regions.
• Encore Wire Corporation: U.S. manufacturer of copper and aluminum wire and cable products for residential, commercial, and industrial applications. Encore Wire overlaps with Mueller's Nehring Electrical Works and Conex Cable subsidiaries in copper and aluminum conductors serving utility and electrical markets.
• Modine Manufacturing: U.S. manufacturer of heat transfer and thermal management products for HVAC, refrigeration, data center cooling, and automotive applications. Modine's data center cooling and HVACR heat exchanger business directly overlaps with Mueller's Turbotec, Westermeyer, and ATCO Flexible Duct subsidiaries.
• Howden Group (Chart Industries): Global manufacturer of heat transfer and cooling products including heat exchangers, cold boxes, and cryogenic equipment serving HVAC, refrigeration, and industrial gas markets. Chart Industries overlaps with Mueller's Climate Products segment and pressure vessel manufacturing at Westermeyer Industries.

Others

• Radius Recycling (formerly Schnitzer Steel): North American recycler and producer of recycled metal products including copper. While not a direct product peer, Radius is an upstream copper supplier and adjacent comparator in the copper value chain relevant to Mueller's vertically integrated copper sourcing.

Broad incumbents

• Commercial Metals Company: U.S. manufacturer of steel and metal products including rebar, structural steel, and related fabricated metal products. CMC provides broad incumbent comparability to Mueller through its fabricated metal products portfolio, though CMC is primarily steel-focused rather than copper-centric.
• Aurubis AG: European integrated copper producer covering smelting, refining, and recycling through to semi-finished copper products. Aurubis overlaps with Mueller in rod and copper products but operates a much broader upstream value chain, making it a broad incumbent comparator.
• Olin Corporation: Diversified manufacturer with a significant brass and copper alloy products (Olin Brass) segment producing copper sheet, strip, and fabricated components. Olin's brass products overlap with Mueller's Industrial Metals segment while its broader chemicals and ammunition businesses make it a broader incumbent.
