Net profit was Rs 106.93 crore in the same period of the previous year, the company said in a regulatory filing. Total income increased by 18.78 per cent to Rs 2,642.98 crore in July-September of 2017-18, from Rs 2,225 crore in the year-ago period.

Revenue from domestic sales rose by 30.10 per cent to Rs 1,850.96 crore in the period under the review, from Rs 1,422.70 crore a year earlier, while that of exports increased marginally by 5.41 per cent to Rs 771.36 crore, from Rs 731.91 crore previously.

Expenses remained slightly higher at Rs 2,425.15 crore in the second quarter as against Rs 2,072.34 crore in the year- ago period. Terming the rollout of the goods and services tax (GST) as a very major structural change, the company said it has resulted in a major "disruption" for unorganised players in all the sectors of the economy.
