9 February 2019 INR6.2b) in 3QFY19 owing to lower volumes/realizations and higher cost of production (CoP). The miss versus our estimate can primarily be ascribed to higher Production increased 12% QoQ to 532kt, but sales were down 10% QoQ to 293kt. Production was down 8% QoQ to 105kt, while sales were down USD2,241/t, even as LME was lower, due to higher product premiums. CoP increased USD172 QoQ to USD2,109/t, accentuated by reduced volumes leading to lower absorption of fixed cost. NACLs performance was impacted by alumina prices coming off their recent highs and fixed cost absorption being lower due to reduced volumes. We expect volumes to improve, which should drive down CoP, but the alumina benchmark prices have fallen further as Chinese supply is rising. We cut our alumina price estimate from USD400/t to USD350/t for FY20-21. We have also marginally cut aluminum product premiums and increased CoP.
