CDSL has a diversified revenue stream, ~35% of the revenue is annuity in nature and ~42% is market linked (Transaction, IPO/corporate action and KYC). The opportunity related to demat of ~60K unlisted public companies is unfolding and hike in Annual issuer charges is also due in FY21E. Transactions charges/KYC revenue will revive with retail participation and improved market sentiments. New revenue streams like NAD and e-warehouse receipts are future growth drivers. We expect revenue/EBIT/PAT to grow at a CAGR of 13/10/10% over FY19-22E. Net cash stands at Rs 6.50bn (~23% of Mcap) and the company trades at a P/E of 22/19x FY21/22E earnings. Risks include regulatory changes, market slowdown and increase in competition. We maintain BUY on CDSL based on inline revenue and better margin performance in 3QFY20. Growth in Annual issuer charges and revival of transaction revenue is driving growth. Regulatory tailwinds like hike in Issuer charges and compulsory demat of unlisted companies and Insurance policies will provide further boost to growth. We value CDSL on SoTP basis by assigning 30x to Dec-21 core profit and adding net cash to arrive at a TP of Rs 325.
