As per Mgmt. in the concall:
Lasa sales in FY17 = Rs.200 Crs. (FY16 Rs.136 Crs.)
Lasa Margins = 22% [(Mgmt says this should be normalised margins in future (to be taken with a pinch of salt)]
Lasa Debt = Rs.58 Crs. (Rs13 Crs. transferred from Omkar + Rs.48 Crs on its on books)
One can do his own calculations with assumptions on interest, depreciation, tax and what multiples to assign.
Even if it is able to do Rs.20 Crs. of Net Profit then at 15 times this works out to Rs.300 crs of market cap for Lasa whereas Omkar today trades at Rs.375 Crs.
Discl.: Added today and may add more.
