Keller Michael D 4

What Happened

• Michael D. Keller, Vice President and Corporate Controller of Nucor Corporation (NUE), was issued a grant of 717 restricted stock units (RSUs) (reporting code A) and had a total of 827 shares withheld (reporting code F) to satisfy tax liabilities related to prior RSU vestings.
• The withheld shares were reported as dispositions: 312 shares @ $250.00 each ($78,000), 268 shares @ $250.00 each ($67,000), and 247 shares @ $250.00 each ($61,750), totaling 827 shares and $206,750. The 717 RSUs were reported as acquired at $0 (they are units, not immediately issued cash).

Key Details

• Transaction date(s): June 1, 2026; Form 4 filed June 3, 2026 (appears timely).
• Prices and amounts: 312 @ $250.00 = $78,000; 268 @ $250.00 = $67,000; 247 @ $250.00 = $61,750; grant of 717 RSUs @ $0.
• Shares owned after the transactions: not specified in the excerpted filing.
• Footnotes: Withheld shares (codes F1–F3) represent shares surrendered to pay tax liabilities from RSU vestings reported on prior Form 4s (6/5/23, 6/4/24, 6/3/25). The newly reported 717 RSUs (F4) convert to one common share each when vested; they vest in three annual installments beginning June 1, 2027, subject to acceleration on death, disability, retirement, or change in control.
• Transaction codes: A = Award/Grant; F = Payment of exercise price or tax liability (here, tax withholding), not an open-market sale.

Context

• This filing reflects routine tax-withholding on previously vested RSUs and a new RSU grant. Withholding (code F) is not the same as an open-market sale and does not necessarily indicate a change in the insider’s view of the company.
• The 717 RSUs are restricted and will vest over time (starting in 2027); they are not immediately tradable shares.
