After these transactions, the reporting person directly beneficially owned 35,847 shares of Class A common stock.

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.
Post-trade holdings: direct Class A stake drops to 13,958 shares (from 37,920 pre-sale). Indirectly, the director still controls 29,747 Paired Interests through Core & Main Management Feeder, LLC. The transactions appear to be personal portfolio rebalancing and do not alter CNM’s capital structure or provide new financial guidance.
Core & Main, Inc. (CNM) – CEO Form 4 filed 21-Jul-25
On 17-Jul-25, Chief Executive Officer & Director Mark R. Witkowskiconverted 100,000 “Paired Interests” (Class B common stock + LP units) into an equal number of Class A shares at $0 cost under the 2021 Exchange Agreement. The shares were then sold the same day, pursuant to an April-25 Rule 10b5-1 plan, in two open-market blocks: 72,331 shares at a weighted-average $61.1239 and 27,669 shares at $61.6298, raising roughly $6.1 million.
Following the sales, Witkowski’s direct Class A stake fell from 135,847 to 35,847 shares. He retains indirect exposure to 716,250 Class A-equivalent units through Core & Main Management Feeder, LLC and another 100,000 exchangeable Class B/LP units held directly, so the officer continues to hold a sizeable economic interest despite the disposition.
No new derivatives were granted; activity reflects routine conversion and liquidity management. Nevertheless, the disposition of the full 100 k converted shares (≈74% of direct holdings) represents a meaningful reduction in the CEO’s freely-tradable stock and may be viewed by investors as a modestly bearish signal, partially offset by pre-planned execution and remaining indirect ownership.
