Ambuja Cements reported a 90 percent year-on-year decline in consolidated net profit to Rs 236 crore for the September quarter, as higher fuel and logistics costs weighed on profitability despite an improvement in its trade and premium product mix. The profit decline also needs to be seen against a high base. The year-ago quarter’s profit after tax included a reversal of income tax provisions worth Rs 1,697 crore, the company said.
