Infosys Technologies announced its fourth quarter results for fiscal year 2010 on April 13th, reporting a 1.14% increase in quarterly profits. Revenues increased 3.54% for the quarter. However, operating margins declined slightly. The company also provided guidance for fiscal year 2011, expecting earnings per share growth of 4.3-8.6% but lowered revenue guidance in rupee terms to 9-11% due to rupee appreciation. Challenges for the company include a potential interest rate hike by the RBI, currency fluctuations, and increased competition.
