Fidelity National Information Services, Inc FIS is set to release first-quarter 2016 earnings results on May 3. In the last quarter, the company reported in line earnings. However, it has a positive four-quarter average earnings surprise of 0.40%.Let’s see how things are shaping up for this announcement.Why a Likely Positive Surprise?Our proven model shows that Fidelity is likely to beat earnings because it has the right combination of two key ingredients. A stock needs to have both a positive Earnings ESP and a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold) for this to happen. The combination of Fidelity’s Zacks Rank #3 and earnings ESP of +2.70% makes us confident in looking for an earnings beat this quarter.Factors to ConsiderFidelity’s commanding position in the financial services market, increasing international exposure, recurring revenue model, diversified product portfolio, cost synergies from acquisitions and a loyal customer base are significant positives.Moreover, we believe that Fidelity is well positioned to benefit from increasing investment in mobile banking and innovative products such as PayNet. Mobile banking is developing into an essential extension of online banking as smartphone and tablet usage continue to accelerate globally.Also, accretive acquisitions have played an important role. The acquisitions of Metavante and Capco not only expanded its product and solutions portfolio but also provided significant synergies that drove top and bottom-line growth. In Nov 2015, the company acquired prominent financial software and technology services provider, SunGard for approximately $9.1 billion. The new company is expected to generate pro forma revenues of $9.3 billion in a year with employee strength of 55K.However, the company has also been seeing weakness in its Professional Services business and sluggish demand from its large and global financial institution clients, which can pose some challenges. In addition, increasing consolidation in the banking sector, a challenging environment for the Payments Solutions business, stiff competition and an uncertain regulatory environment are the headwinds.Stocks to ConsiderHere are a few stocks you may want to consider as our model shows that these have the right combination of elements to post an earnings beat this quarter:Quotient Technology Inc.
