Winston Score History

The full picture

Mueller Industries makes copper and brass products used in buildings, appliances, and industrial equipment. Its main products include copper tubes, fittings, and valves — the kind found inside walls carrying water or refrigerant in homes and commercial buildings. The company is one of the largest manufacturers of copper fittings in North America.

Mueller earns money by selling these metal components to wholesalers, contractors, and manufacturers across the United States, Canada, and Europe. It operates dozens of manufacturing facilities and generates roughly $3–4 billion in annual revenue. Its competitive edge comes from its scale, low-cost manufacturing, and long-standing customer relationships in a market where switching suppliers is uncommon. The main risk the company faces is the price of copper, its key raw material, which can swing sharply and pressure profit margins even when demand stays steady.

Revenue accelerating

Mueller Industries grew revenue 25% year-over-year and the growth rate is speeding up. That's the kind of momentum growth investors look for — the question is whether margins can follow.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
