"In the current year we are looking at around Rs 150-200 crore of capex which may get spilled over to FY2018 also," Unichem Laboratories VP Finance and CFO Rakesh Parikh said in an analyst call.
The API unit is coming up and it has a major capital expenditure, he said, adding that "the work out there is going on in full swing".
Commenting on the expansion of its Goa plant, Parikh said the facility will be commissioned in the current quarter.
"Significant amount of capital expenditure was incurred last year (on the Goa plant) and the same is the case with our biosciences pilot plant," he added.
The other expenditure is more or less maintenance and de-bottlenecking work at the existing plants, Parikh said.
Unichem Laboratories stock closed at Rs 261.90, down 0.72 per cent, on BSE.
