So recently that had done a Private equity placement with the 360 One Funds, @Rs.235/share for 475Cr. (Link)
Since the IPO is a Fresh Issue for Rs.3500Cr, and assuming same valuation of Rs.235, this will be for 14.89Cr shares. But I suspect this might be at a higher valuation. Current equity is 98.88Cr, this will be a ~15% equity dilution. This also pushes Aegis equity stake below 50%.
