RAW MATERIALS STRATEGY DRI Plant - Louisiana Game changer for Nucor’s cost of high quality iron units required to produce higher value-added sheet, SBQ, & plate Production of DRI began on December 24, 2013 Output quality matching the best-in-class levels routinely achieved at our DRI plant in Trinidad. Together with Trinidad plant, Nucor has total annual DRI capacity of 4.5 million metric tons. Natural Gas Working Interest Investment Long-term & low cost supply of energy source required to produce DRI Provides hedge against any future increases in natural gas prices – critical risk factor in DRI production Approximately 20 year supply of natural gas to cover usage of 2 DRI plants + current steel mill consumption Cost structure of drilled wells such that they delivered modest positive return in 2013’s low natural gas pricing environment DRI = Direct Reduced Iron

NUCOR’S FOCUS = GENERATE ATTRACTIVE RETURNS

BUILDING EARNINGS POWER FOR THE NEXT CYCLICAL PEAK & BEYOND (Millions of dollars) 2008 RECORD EPS $5.98 HIGHER HIGHS = 2008 NET INCOME OF $1.831 BILLION WAS SIX TIMES GREATER THAN 2000 NET INCOME OF $311 MILLION HIGHER LOWS = 2009-2011 NET INCOME TOTALING $619 MILLION WAS 80% GREATER THAN 2001-2003 NET INCOME TOTALING $338 MILLION Our focus remains on achieving “HIGHER HIGHS” through the cycle – setting a new earnings record at the next cyclical peak. We have made significant investments in recent years that our shareholders have not yet been “paid for” due to where we have been in the economic/steel cycle – those returns are ahead of us in the next cyclical upturn!!!
