OCI Ramp-Up of Methanol Capacity

Iowa Fertilizer Company | Continues to Push Maximum Capacity Higher IFCO Reaches Record Utilization Rates ■ IFCO reaches record utilization levels following 4-week debottlenecking in Q3 2019, and at better gas efficiency: Consistent performance during 2019 YTD ◉ Record of 117% of nameplate capacity reached in September 2019 despite warm weather (which generally limits production) IFCO is expected to continue to benefit from increasing MPC in 2020 DEF volumes also continue to ramp up: IFCO Reaches Record Utilization Rates Ammonia (Production kst) 300 250 81% 200 77% 150 100 50 110% 120% 109% 107% 104% 103% 98% 97% 100% 80% 60% 40% 0 20% Q2'17 Q3'17 Q4'17 Q1'18 Q2'18 Q3'18 Q4'18 Q1'19 Q2'19 Production (KST) Capacity Efficiency % OCI Higher margin product with less seasonality than fertilizers; market growth in the US >15% IFCO on target to double DEF sales volumes in 2019 (from c.260kt in 2018), further strong growth expected in 2020 towards 1 mtpa capacity Diesel Exhaust Fluid Volumes Set to Double (Production kst) 180 160 140 120 100 80 60 40 20 0 Q2'17 Q3'17 Q4'17 Q1'18 Q2'18 Q3'18 Q4'18 Q1'19 Q2'19 Production (KST) Capacity Efficiency % 80% 60% 40% 20% 0% 9800 9
