[Form 4] Core & Main, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Core & Main, Inc. (CNM) filed a Form 4 reporting insider activity by director Orvin T. Kimbrough on 18 Jul 2025. The filing shows multiple equity-for-unit exchanges and one sizeable open-market sale.

Key actions: (1) Redemption of 5 vested management units into 5 Class A shares; (2) exchange of 23,957 Class B shares & limited-partnership interests ("Paired Interests") for 23,957 Class A shares at $0; (3) open-market sale of 23,962 Class A shares at a weighted-average $61.7684 under a Rule 10b5-1 plan, generating roughly $1.48 million; (4) 1,038 derivative units withheld for distribution adjustments.

Negative

• Director sold 23,962 Class A shares (~$1.48 million), reducing direct stake to 13,958 shares.

Insights

Securities Analyst

TL;DR: Planned insider sale of ~24k CNM shares; net holding reduced but activity largely neutral to fundamentals.

The largest economic move is the sale of 23,962 Class A shares for c.$1.48 mm. While insider selling can signal reduced conviction, the sale was executed under a pre-arranged Rule 10b5-1 plan, lessening the informational value. The bulk of reported line items are technical exchanges from Class B/LP units into freely tradable Class A shares—non-cash, non-dilutive events. Post-sale, the director still owns nearly 14k shares outright and retains substantial indirect exposure via 29,747 Paired Interests. Absent earnings data or company actions, the filing is not materially impactful for valuation or near-term trading.
