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.
Form 4 filing for Core & Main, Inc. (CNM) dated 07/03/2025 documents transactions executed by Chief Financial Officer Robyn L. Bradbury on 07/01/2025.
The filing shows a series of unit redemptions, share conversions and open-market sales that collectively alter the officer’s ownership position:
- Conversion/Redemption: 24,957 Class B shares and corresponding partnership interests were exchanged for an equal number of Class A shares (Code C), and 43 management-feeder units were redeemed for 43 Class A shares (Code J). Both transactions were executed at $0 and increase the freely tradable Class A float.
- Open-market sales: A total of 25,000 Class A shares were sold in three tranches under a pre-arranged Rule 10b5-1 plan (Code S) at weighted-average prices of $59.97, $61.08 and $61.58, generating roughly US$1.5 million in gross proceeds.
- Post-transaction holdings: Direct ownership falls to 8,555 Class A shares, while 22 Class A shares and 162,447 derivative units remain indirectly held via Management Feeder LLC.
Although the sales were executed under a 10b5-1 plan, the CFO’s net reduction in directly held shares may signal decreased personal exposure to CNM equity. Conversely, the one-for-one conversions simplify the capital structure and modestly expand the public float. Investors typically view sizable insider sales by senior executives as a potential negative sentiment indicator, but the impact is tempered by the orderly, pre-planned nature of the transactions.
