[Form 4] NUCOR CORP Insider Trading Activity

Rhea-AI Filing Summary

Nucor Corporation reported insider share withholding for tax purposes by a senior officer. A company officer serving as Vice President and Corporate Controller reported several transactions in Nucor common stock dated 12/06/2025. In these transactions, 528, 1,054 and 881 shares of common stock were disposed of at a price of $160.955 per share, leaving 20,000.71 shares beneficially owned after the last reported transaction.

The footnotes explain that each disposal represents shares withheld by Nucor to cover tax liabilities triggered by the vesting of previously awarded restricted shares, originally reported on filings dated 2/22/23, 2/21/24 and 2/19/25. These are administrative tax-withholding events rather than open-market sales.
