A tax writeback of Rs 372 crore, however, helped the company report net profit growth of 59 per cent year-on-year. However, adjusted for one-offs, profits were down 16.6 per cent year-on-year, according to analysts. Per tonne profitability declined by about a third year-on-year to Rs 495. This was lower than Rs 513 reported by ACC. UltraTech and Shree Cement, on the other hand, reported much higher per tonne profitability of Rs 772 and Rs 1,067, respectively. Meanwhile, Ambuja is accelerating efforts on alternative fuels, optimised fuel mix, plant efficiency improvements and new coal block commissioning. This will help optimise the fuel mix further. The company's new 4.6 MT of cement greenfield capacity in Rajasthan is being set up. However, analysts remain cautious for the near term. For one, the benefits of capacity expansions are expected to accrue only by the end of CY20 and analysts at Edelweiss Securities expect volume growth to stay muted.
