The country's second largest software services exporter, Infosys, on Friday posted its October-December earnings which were lower than analysts\u2019 estimates as subdued growth in services and cautious spending by clients created pressure. Still, the company raised its revenue growth forecast for FY19 to 8.5-9% in constant currency, from 6-8% previously. Infosys also approved a buyback of shares worth Rs 8,260 crore at a price not exceeding Rs 800 per share, which is at a 17% premium to its current market price of Rs 683.50. It also announced a special dividend of Rs 4 per share that would be a payout of approximately Rs 2,107 crore.
