IMS was bought by TPG Capital, the Canada Pension Plan Investment Board and Leonard Green & Partners in a $5.2bn take-private deal including debt.
It chose JPMorgan as lead underwriter for the exit process after interviewing investment banks late last week according to Reuters, which cited people familiar with the matter.
The report said Morgan Stanley and Goldman Sachs would also lead the offering, which is planned for some time in 2014.
IMS Health has picked up 11 add-on companies since its 2010 buyout, five in the last year alone.
The company currently has more than 5,000 clients across 100 countries according to its website.
