Under Armour, Inc. UA, the developer, marketer and distributor of branded performance apparel, footwear, and accessories, is slated to report first-quarter 2016 results on Apr 21. The big question facing investors is, whether the company will be able to deliver a positive earnings surprise in the quarter to be reported. In the trailing four quarters, the company outperformed the Zacks Consensus Estimate by an average of 9.4%. Let’s see how things are shaping up for this announcement.Zacks Model Shows Unlikely Earnings BeatOur proven model does not conclusively show that Under Armour is likely to beat earnings estimates this quarter. This is because a stock needs to have both a positive Earnings ESP and a Zacks Rank #1, 2 or 3 for this to happen. Under Armour has an Earnings ESP of 0.00% as the Most Accurate estimate and the Zacks Consensus Estimate both stand at 2 cents. The company carries a Zacks Rank #3 (Hold), which increases the predictive power of ESP. However, the company’s ESP of 0.00% makes surprise prediction difficult.Factors Influencing this QuarterUnder Armour’s sustained focus on brand development, expansion of its DTC business, product innovation and foray into the technology-based fitness business bode well. Management had earlier projected first-quarter 2016 net revenue growth in the high 20% range. However, it had also hinted that gross margin may contract 150 basis points during the quarter on account of higher inventory liquidation and currency headwinds.Stocks Poised to Beat Earnings EstimatesHere are some companies you may want to consider as our model shows that these have the right combination of elements to post an earnings beat:McDonald's Corp. MCD has an Earnings ESP of +1.74% and a Zacks Rank #2 (Buy).Lithia Motors Inc. LAD has an Earnings ESP of +0.65% and a Zacks Rank #2.Cabela's Incorporated CAB has an Earnings ESP of +10.81% and a Zacks Rank #3.Want the latest recommendations from Zacks Investment Research?
