Warburg Pincus, a global private equity firm, completed the acquisition of a 90% stake in Vistaar Finance, an Indian small-business lender, for $250m. ''We believe micro-enterprises in semi-urban and rural India are underserved by formal sources of credit and we believe Vistaar has the potential to fulfil that need gap and be a driver for broad-based growth in those regions and communities. Warburg Pincus has a deep history in partnering with exceptional teams, particularly within financial services and looks forward to a similarly exciting future at Vistaar,'' Narendra Ostawal, Warburg Pincus Managing Director.
