Insights

Equity compensation analyst

These entries show routine tax withholding on vested RSUs, not open-market selling.

The transactions involve Form 4 code F, which the data describes as payment of tax liabilities by delivering securities. A total of 475 shares of Core & Main Class A common stock were withheld when restricted stock units vested for CFO Robyn L. Bradbury.

Because the issuer withholds shares instead of the executive selling stock in the market, these disposals usually carry limited informational value about the insider’s view of the company. Bradbury’s filings also show 8,080 directly held shares and 22 indirectly held via an LLC, indicating a continuing equity stake after the tax events.
