To answer your Q,
Their term debt is only 100cr, debt/EBITDA is 0.6. They have ample space on their balance to take on further capex
Most of their debt is working capital debt . As their revenue increases this will increase in line with their revenue. They have capped interest cost at 3.3% of their gross sales which I think is reasonable and over time they have guided to a reduction.
Even if they were to knock off their short term borrowings it would not help or make sense , if they buy steel from a steel company they have to give a LC , if they purchase a machine worth say for 15cr they have to give LC, for everything they do LC will be required so knocking off short term borrowings does not really help
I can’t figure out why debt repayment is bothering you, term debt is only 100 cr , they are deploying more than 100 cr is capex each year , they generate high cash profit each year which is re deployed to generate a higher eps.
Company is in a stage where they are deploying all cash profit to build more capacities plus to fund this capacity they borrow working capital
A time will come when there capex plans are complete and they will not deploy cash for capacities, when that time comes can you IMAGINE the kind of FCF they would generate???
