UltraTech Cement on Thursday reported a 13.59% drop in consolidated profit at Rs 394 crore for December quarter. The company had reported Rs 456 crore net profit in the year-ago period. Net sales rose 19% to Rs 9,258 crore from Rs 7,779 crore last year. Domestic sales volume grew 15% year-on-year. Net profit was adversely impacted by 11% rise in costs driven by higher fuel expenses and a deteriorating rupee. Interest cost too jumped on account of higher loans raised for the acquisition of UNCL (formerly Binani Cement), the company said in a regulatory filing.
