16 Major end-markets summary Flat-Rolled Segment United States Steel Corporation Automotive 2015 auto sales set a new record at 17.47 million vehicles; up 3% versus 2014. Inventories finish year at same 61 days of vehicles; NAFTA built inventory slightly lower. 2016: N.A. production forecast up to 17.7 million; USA sales forecasted to exceed 2015 volume. Industrial Equipment Construction equipment demand steady, and expected to benefit from regional USA weather events. Mining equipment demand remains low due to lower international commodity prices and currency. 2016 railcar demand & backlogs remain steady, but no appreciable increase forecasted. Tin Plate AISI reports that apparent consumption of tin mill products through October is down 3.2%. However, domestic mill shipments are off -13.1% YTD. Imports up 14% in 2015 and now account for 40% of U.S. tin mill market. Appliance 2015 major unit shipments increased 6.3% y-o-y, with December registering 10.3% y-o-y growth, according to the Association of Home Appliance Manufacturers (AHAM); 2016 shipment outlook not yet available, but should follow positive trend expected for residential construction growth. Pipe and Tube Structural tubing demand steady supporting construction and distribution. Line pipe project activity decreased in 4Q15 and early 1Q16, due to budgeting and lower energy prices. No meaningful improvement expected for welded OCTG in 2016. Construction YTD USA construction square footage contract awards through Nov up 4% versus 2014 but uneven across the industry; Residential up 12% in 2015, yet Non-Residential down 10%. US Housing Starts up 10.5% in Nov to a SAAR of 1.17 million; 8 consecutive months > 1 million. YTD construction spend is up 10.7% versus 2014, but unexpectedly fell 0.4% in Nov. Service Center MSCI Carbon Flat Rolled shipments in 2015 fell over 7%; both Hot Rolled and Coated the big declines. Months supply of flat roll inventory still high at 3 months based on low shipping volumes; however, carbon flat rolled inventory was reduced by 12.5%, or 772,600 tons, during 2015. Total steel products trended similarly to carbon flat rolled, with lower y-o-y shipments, and a large inventory reduction during 2015.

18 Major end-markets summary United States Steel Corporation U. S. Steel Europe Segment Sources: Eurofer, USSK Marketing, IHS, BDS Automotive In 4Q, EU car production reached 4.4 million units, an increase of 5.4% y-o-y. Total EU 2015 car production is forecasted to end up 6.7% higher to 18 million units. In 1Q 2016, EU car production is expected to amount to 4.9 million units, an increase of 3.6% y-o-y. Total EU 2016 car production is forecasted to grow by 1.8% to roughly 18.3 million units. V4 car production is anticipated to increase by 12% y-o-y in 4Q and for the full year 2015 we expect 10% growth y-o-y to 3.3 million units. In 1Q 2016, we expect V4 car production to normalize and to amount to 0.9 million units, a decrease of 2.9% y-o-y. Total V4 2016 car production is forecasted to grow by 0.2% to roughly 3.31 million units. Appliance In 4Q, the EU appliance sector declined by 3% y-o-y. Overall 2015 EU domestic appliances market is projected to grow by 3% y-o-y. Key players pushing trend up were Germany, France and Italy with stable economic and residential property sectors. In 1Q 2016 we expect growth of 4% y-o-y; 2016 projection is 2% y-o-y growth. Central Europe will continue to achieve slightly higher performance compared to the EU average. Tin Plate Although 4Q consumption fell 9.5% q-o-q, the drop was much lower then in the previous couple of years. Hence the 2015 consumption of tinplate is expected to reach 3.9 million MT or 3.8% y-o-y growth. No major improvement in the EU tinplate market is expected for 2016 as the imports from Asia are becoming more aggressive; we may see some shift of purchased volumes from the EU producers to Asian importers, especially in middle-range can makers segment. Construction The economic recovery in the EU remained broadly on track in 2H 2015. Performance of the construction subsectors remained primarily driven by the residential market. Total EU construction activity is forecast to rise by 1.5% in 2015. The outlook for 2016 is for a further improvement of sector fundamentals. Lower oil prices and an improving labor market combined with expected easing in access to and cost of financing should also lead to improving non-residential demand. All in all, output in 2016 is expected to rise by 2.5% y-o-y after a forecasted 0.4% increase for 1Q 2016. Service Centers Data for 4Q signals that ex-stock sales of flat rolled products improved compared with the monthly average of 3Q. As inventories did not change significantly, there was a slight reduction of the inventory-sales ratio.
