The transaction values Arinna at an enterprise value of Rs 200 crore on a cash and debt free basis. After accounting for necessary adjustments to the enterprise value of Arinna, the purchase consideration has been determined to be approximately Rs 175.92 crore for secondary acquisition of 85% equity shareholding in Arinna on a fully diluted basis at a price of approximately Rs 158.53 per share. The final consideration remains subject to adjustments on the closing date.
