Core & Main (CNM) primarily sells to other companies and organizations, making it a business-to-business (B2B) operation.

As a leading distributor of water, wastewater, storm drainage, and fire protection products, Core & Main serves a highly diversified customer base across the United States. Due to the nature of their distribution business, no single customer or group of related customers accounts for a significant portion (typically 10% or more) of their consolidated net sales. Therefore, no specific "major customer companies" are individually identified in their public filings.

Instead, Core & Main's customer base can be broadly categorized into the following types of entities:

• Municipalities: Local and state government entities responsible for the development, maintenance, and repair of public water, sewer, and storm drain infrastructure. These are not public companies with stock symbols.
• Private Water Companies: Privately owned utility companies that provide water and wastewater services to communities. While Core & Main likely supplies products to these companies or their contractors, no specific private water company is disclosed as a major customer. Examples of large publicly traded water utility companies in the U.S. include American Water Works (AWK) and Essential Utilities (WTRG), but these are not confirmed major customers of CNM.
• Professional Contractors: Companies specializing in the construction, repair, and upgrade of water, wastewater, storm drainage, and fire protection systems for both public and private sector projects. These contractors often work on behalf of municipalities and private water companies. Many of these contractors are privately held, and none individually represent a major customer for Core & Main.
