4 Growth In Recycling Of Steel & Input Prices  For every 100 tons of steel manufactured currently,121 tons of steel are recycled –Caused by steady pricing of steel over past 4 years in comparison to Iron Ore  Amount of steel being recycled growing at a CAGR of 7.8%,  Project growth at a conservative decreasing rate*, yet still reflects an increase in use of Scrap Steel as input – This projects an increase in manufacturing using scrap steel of 3.4% YoY *Projections are reduced by multiplying implicit CAGR by.90 per year ( steel.org/~/media/Files/SRI/Releases/ %20- %202010%20Steel%20Recycling%20Rate%20Releases.ashx)

5 Cost Advantage: Electric Arc Furnace  To Produce 1 Ton of Liquid Steel –BOF: 1400kg iron ore, 770kg coal, 150kg limestone & 120kg recycled steel –EAF: 880kg recycled steel, 150kg coal, 43kg limestone 1  Currently EAF = $392.5 BOF = $ Production amounts calculated from World-Steel.org, Differences in production between the two as both include ferroalloys etc. 2 Price calculated from input costs from steelonthenet.com (10.7%) 2010 (12.3%) 2011 (9.6%) EAF production cost per ton decreases unit cost by roughly (9.6%) 3

6 Growth In Total Production Exclusively Through Electric Arc Furnaces  Production of Steel through EAF has increased from 47.4% to 61.3% in past decade (2.6% CAGR) –Drawn to EAF by 1) more stable scrap prices 2) decreased cost per unit 3) lower emissions  Applying a modest 1.5% growth rate this is transforming much of steel manufacturing into Electric Arc Furnaces.  This growth coupled with decreased production costs will increase gross margin by.32% YoY 1 1 Calculated by multiplying growth rate by discount on operating costs. The number may seem small but would be saving NUE $46,194,549 ($.014PS) per year on cost of production assuming switch.
