QUERY KENNETH REX 4

What Happened

• Kenneth Rex, Executive Vice President of Nucor (NUE), received equity awards and had shares withheld to satisfy tax obligations. On 2026-06-01 he was granted 2,875 shares (issued) and 2,303 RSUs (derivative RSUs). On the same date the issuer withheld 6,438 shares to cover tax liabilities related to previously vested restricted stock units; those withheld shares were recorded as disposals at $250.00 per share, totaling $1,609,500.
• These actions are not open-market sales or purchases by the insider. The withheld shares represent tax withholding (transaction code F) and the zero-dollar share entries are grants/awards (transaction code A).

Key Details

• Transaction date: 2026-06-01; Form filed: 2026-06-03 (appears timely).
• Withheld/disposed: 3,048 shares ($762,000), 2,401 shares ($600,250), 989 shares ($247,250) — total 6,438 shares withheld for taxes at $250.00/share = $1,609,500.
• Acquired (grants): 2,875 shares @ $0.00 (issued) and 2,303 RSUs @ $0.00 (derivative) — total 5,178 shares/RSUs granted.
• Footnotes: F1–F3 indicate the withheld shares relate to tax liabilities from previously awarded RSUs (vests reported on Forms dated 6/5/23, 6/4/24, 6/3/25). F4 clarifies the 2,303 RSUs are derivative units that vest in three annual installments beginning 6/1/2027 (with acceleration in certain termination/change-in-control events). F5 notes employee stock option terminology (not central to these entries).
• Shares owned after the transactions are not specified in the provided excerpt.

Context

• The disposals are tax-withholding (common when RSUs vest) rather than open-market sales; they do not necessarily indicate a change in insider sentiment. The grants (zero purchase price) are restricted stock units that convert to shares when they vest; the 2,303 RSUs are subject to a multi-year vesting schedule starting in 2027.
