Mueller Water Products, Inc.

We primarily sell to national and regional waterworks distributors in the United States and Canada. Our distributor relationships are generally non-exclusive, but we attempt to align ourselves with key distributors in the principal markets we serve. We believe “Mueller” is the most recognized brand in the United States water infrastructure industry. Our extensive installed base, broad product range and well-known brands have led to many long-standing relationships with the key distributors in the principal markets we serve. Our distribution network covers all of the major locations for our principal products in the United States and Canada. Although we have long-standing relationships with most of our key distributors, we typically do not have long-term contracts with them, including our two largest distributors, which together accounted for approximately 37%, 38% and 35% of our gross sales in 2025, 2024 and 2023 fiscal years, respectively. See “Item 1A. RISK FACTORS - Our business depends on a small group of key customers for a significant portion of our sales.”
