I fail to understand your statement.
80% of Sales? So margins for PBT are < 20%?
June 2018, Sales = 138 Cr, PBT = 9. margin = 6.5%
June 2017, Sales = 111, PBT = 5. margin = 4.5%
Margins improve, no brainer, sales 35% Up and PAT 92% Up.
Expenses,
June 2018, Materials = 111 Cr
June 2017, Materials = 92 Cr
20% increase, whereas Topline grows by 35%.
Let them keep climbing, if they are indeed climbing, as long as margins/PAT climbs faster.
