We assign a P/E multiple of 33x to core earnings and add net cash to arrive at a TP of Rs 425 (47% upside from CMP). At 24/21x FY19/20E earnings, value is imminent and merits a BUY. Central Depository Services Ltd (CDSL) is one of two depositories in India and the only one to be listed. Given the high risk of data pilferage, we believe there is limited scope for any other depository to be set up. CDSL is a gem of a business that any investor constructive on India in the long term must own. It has a robust business model, with (1) One-third of revenues being annuity (issuer charges), (2) Embedded non-linearity playing out (1,502 bps margin expansion over FY13-17), (3) Low capex requirement (~3% of revenue), (4) Excellent cash generation (OCF ~63% of EBITDA) and (5) Huge option value from new areas like digitisation of academic records and insurance policies, e-warehouse receipts and GST Suvidha centres.
