Nucor Corporation filed an Amendment No. 1 to its Current Report on Form 8-K to include the Executive Employment Agreement for John L. 'Jack' Sullivan. Mr. Sullivan's promotion to Chief Financial Officer, Treasurer, and Executive Vice President became effective March 1, 2026. His annual base salary increased to $680,000, effective March 1, 2026. The agreement details 'General Non-Compete Benefits' payable upon termination (excluding death), contingent on signing a release, equal to the greater of six months of base salary or one month of base salary per year of service, with a minimum for executives under age 55. In the event of an involuntary termination or resignation for 'Good Reason' within 24 months of a change in control, Mr. Sullivan is entitled to 'Change in Control Non-Compete Benefits' as a lump sum payment. Change in Control benefits include 2.5 times the sum of his base salary and the greater of 150% of base salary or his average annual incentive plan performance award for the prior three fiscal years, plus the value of equity awards he would have received that year if terminated before the grant date. Medical, dental, and prescription drug coverage would continue for 30 months following a change in control termination. The agreement includes robust restrictive covenants covering confidentiality, non-competition, non-solicitation, and anti-piracy, with a 'Restrictive Period' ranging from 24 to 42 months post-termination, depending on age. Breach of these covenants can result in cancellation of stock options, cessation of benefits, repayment of benefits, and forfeiture of vested stock.
