(Reuters) -Credit reporting agency TransUnion said on Tuesday it will sell its unit TransUnion Healthcare to private equity firm Clearlake Capital Group-backed nThrive Inc in a $1.74 billion all-cash deal. The deal, which is expected to close in the fourth quarter this year, will let TransUnion focus on its core businesses of credit, marketing and fraud mitigation solutions, the company said. Chicago-based TransUnion said the deal is expected to bring in $1.4 billion in after-tax proceeds, which will be used to fund future acquisitions. “The transaction will also allow TransUnion Healthcare to benefit from ownership whose priorities and expertise are solely focused on healthcare revenue cycle management,” TransUnion Chief Executive Officer Chris Cartwright said. The announcement comes more than a month after TransUnion said it would buy information services company Neustar here for $3.1 billion, to expand into digital marketing and fraud prevention. Clearlake said it will combine the newly acquired unit with nThrive, its healthcare-focused software company. Reporting by Niket Nishant in Bengaluru; Editing by Shounak Dasgupta
