Restricted Stock Awards

A summary of Nucor’s restricted stock activity under the Nucor Corporation Senior Officers Annual Incentive Plan (a supplement to the Nucor Corporation 2014 Omnibus Incentive Compensation Plan, the “AIP”) and the Nucor Corporation Senior Officers Long-Term Incentive Plan (a supplement to the Nucor Corporation 2014 Omnibus Incentive Compensation Plan, the “LTIP”) for the first nine months of 2023 is as follows (shares in thousands):

				Grant Date
