SoftBank Corp. (TSE:9434) is in initial talks with the promoters of 91streets Media Technologies Private Limited (PharmEasy) to acquire a stake in India's largest online pharmacy. The move is in line with SoftBank's growing interest in the country's healthcare sector. Sources aware of the discussions said the talks are at an early stage and no term-sheet has been signed, yet. The two sides have been in discussion. Bankers approached SoftBank some time ago, but talks haven't progressed to even a term-sheet stage. SoftBank is exploring it even as the valuation of PharmEasy has gone up," said a source. Another source said that multiple investors have shown interest in acquiring a stake in PharmEasy after it recently picked up 66.1% in Thyrocare Technologies for INR 45.46 billion. In May, PharmEasy had acquired Medlife for an undisclosed amount. While BusinessLine could not ascertain the possible deal size if SoftBank were to pick a stake in PharmEasy, a Bloomberg report said API Holdings Pvt, the owners of PharmEasy, is seeking a valuation of at least $5.6 billion in a new funding round and the Japanese firm could invest $150 million - $200 million into the online pharmacy company.
