Core & Main, Inc.
A specialty distributor that supplies pipes, valves, fittings, storm drainage, water meters, and fire protection gear to municipalities, contractors, and private water companies across the U.S. and Canada, stocking hundreds of thousands of products in more than 370 branches. It was born in 2017 when private equity firm Clayton, Dubilier & Rice carved the waterworks arm out of HD Supply, which itself grew from Home Depot's brief push into wholesale. Its name nods to the "core" essentials of infrastructure and the water "mains" at the heart of what it sells.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 6 months: -3.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
