Founded in Australia in 1978, Computershare has grown via acquisitions to become the world's leading provider of issuer services. Employee share plans and communications services are commonly sold together with issuer services to corporations. The company also has a business services offering and a corporate trust business, alongside a small mortgage administration business that's due to be divested. Over the medium term, around half of group EBITDA is expected to be generated from interest income on client cash balances, or margin income, which is exposed to interest-rate movements.
