Garmin Ltd. GRMN is slated to report first quarter 2016 results on Apr 27. Last quarter, the company posted a 57.45% positive earnings surprise.Let’s see how things are shaping up for this announcement.Factors to ConsiderGarmin reported robust fourth-quarter results with both earnings and revenues surpassing the Zacks Consensus Estimate.The company’s expanding product line in each segment and strong underlying business trends are the positives. Its continued investments in R&D and advertising are expected to result in new revenue opportunities and long-term growth.However, the macroeconomic challenges faced in 2015 remain part of the current operating environment.For 2016, management expects revenues of $2.82 billion. The company expects gross margin of around 54.5%, operating margin of roughly 18%; pro-forma tax rate of nearly 20.5% and pro-forma earnings of $2.25 per share. The Zacks Consensus Estimate for earnings stands at $2.23.The company announced its plan to seek shareholders’ approval for a dividend of $2.04 per share payable in four installments of 51 cents per share each quarter, starting with the Jun 2016 calendar quarter.Earnings WhispersOur proven model does not conclusively show that Garmin is likely to beat earnings this quarter as it does not have 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. That is not the case here as you will see below.Zacks ESP: Both the Most Accurate estimate and the Zacks Consensus Estimate stand at 43 cents. Hence, the difference is 0.00%.Zacks Rank: Garmin currently carries a Zacks Rank #3. Though Zacks Rank #1, 2 or 3 increases the predictive power of ESP, the company’s ESP of 0.00% makes surprise prediction difficult.We caution against stocks with a Zacks Rank #4 or 5 (Sell-rated stocks) going into the earnings announcement, especially when the company is seeing negative estimate revisions.Stocks That Warrant a LookHere are some companies you may want to consider as our model shows these have the right combination of elements to post an earnings beat:Anixter International Inc.
