Outsourcing firm Teleperformance said it agreed to buy Intelenet Global Services Pte. Ltd. from private equity firm Blackstone Group LP in a deal valued at $1 billion.

The target is a business process solutions firm that primarily serves the banking, financial services and insurance sectors. The company generated $449 million in revenue and EBITDA of $83 million in the fiscal year that ended March 31, according to the buyer. Teleperformance said it expects the deal to increase its EPS before amortization of goodwill by about 10% this year.

Teleperformance also said the deal will be financed through debt from BNP Paribas, J.P. Morgan and Natixis.

The deal is expected to close by Sept. 30, subject to regulatory approvals and other customary conditions.
