What it stands on, and what could break it

What the business leans on

1Production depends on copper, brass-making materials such as zinc and tin, aluminum, and energy; copper is obtained through short-term supply contracts and the open market.
2A substantial part of demand for plumbing, heating and refrigeration products depends on new housing, commercial construction, repairs and remodeling.
3Margins on some products depend on the difference between metal input costs and selling prices; Mueller generally passes material-cost changes through to customers, but timing and inventory accounting can affect margins.

What could go wrong

1Changes in the price or availability of copper, scrap, other metals and energy can affect production costs and margins, including when selling prices adjust at a different pace.
2Lower activity in housing and commercial construction can reduce demand for products used in plumbing, heating, air-conditioning and refrigeration systems.
3Imports, trade barriers and substitute products—including plastic plumbing products and aluminum systems in some cooling applications—can reduce demand for Mueller products or affect pricing.
