We expect Infosys Limited INFY to beat earnings expectations when it reports fourth-quarter and full-year 2015 results on Apr 14.Last quarter, the outsourcing company met earnings estimates after beating them for two successive quarters. Also, for the trailing four quarters, Infosys boasts an average positive surprise of 2.4%.We expect the company to post an earnings beat in the about-to-be-reported quarter.Why a Likely Positive Surprise?Our proven model shows that Infosys is likely to beat earnings because it has the right combination of two key ingredients.Zacks ESP: The Earnings ESP, which represents the difference between the Most Accurate estimate and the Zacks Consensus Estimate, stands at +8.70%. This is very meaningful and a major indicator of a likely earnings surprise.Zacks Rank: Infosys carries a Zacks Rank #2 (Buy). Note that stocks with a Zacks Rank #1 (Strong Buy), #2 or #3 (Hold) have a significantly higher chance of beating earnings estimates. Sell-rated stocks (#4 and #5) should never be considered going into an earnings announcement.The combination of Infosys’ Zacks Rank #2 and ESP of +8.70% makes us confident of an earnings beat in the upcoming report.Growth Factors This Past QuarterInfosys’ robust portfolio and ability to create differentiated services through innovation and flexibility are its major strengths as the company seeks to expand its client base.Rapid traction and solid performance of most of Infosys’ business platforms, spearheaded by Finacle, can prove to be a major growth driver. In the quarter under review, Al Ahli Bank in Kuwait, Bank Leumi (UK) PLC and Albaraka, one of Morocco’s leading microfinance institutions, chose to implement the Finacle banking solution for transforming and modernizing their operational technology.Apart from this, the company’s strategic collaborations with leading technology providers in the industry and complementary acquisition plans will likely add to its growth in the to-be-reported quarter. The quarter saw Infosys partnering with technology behemoth Microsoft Corp. to aid the digital transformation of health institutions through the deployment of smart analytics solutions. Also, Infosys partnered with Hershey Company to build predictive analytics capability using open source information platform on Amazon Web Services.The Indian software exporter also signed a 10-year BPO contract extension with M Financial Group during the fourth quarter. Such deals will help generate healthy profits for the company in the quarter under review.Moreover, Infosys’ “Renew New” strategy for driving operational excellence is proving to be highly beneficial. The recent introduction of the customer-centric AiKiDo program under this scheme, will likely supplement the company’s financial performance in the soon to be reported quarter.Infosys has also renewed its focus on digital technology, automation and artificial intelligence in the recent times. This strategy has translated into higher revenues and net profits across its segments, with the Banking & Financial and Retail & Life Sciences segments showing robust growth traction in the last reported quarter. We believe that the growth momentum will reflect positively in fourth-quarter results as well.However, on the negative side, demand for business process outsourcing, which is Infosys’ crucial business segment, has been facing strong competition from nimbler digital technologies such as analytics, mobile and cloud computing.This may prove to be a drag on its financials. Also, foreign currency volatility remains a major headwind for the company and is likely to continue to cast a shadow on the company’s top line through adverse translation effect.Stocks That Warrant a LookHere are some other companies that you may want to consider, as our model shows that these have the right combination of elements to post an earnings beat this quarter:BlackRock, Inc.
