Price and EPS Surprise | Denbury Resources Inc. QuoteLet’s see how things are shaping up for this announcement.Which Way are Estimates Treading?Let’s take a look at estimate revisions to get a clear picture of what analysts are thinking about the company before the earnings release.The Zacks Consensus Estimate of 8 cents for first-quarter earnings has seen one upward and three downward revisions by firms in the past 30 days. This figure indicates a year-over-year decline of 33.3%.The Zacks Consensus Estimate for revenues is pegged at $307.5 million for the to-be-reported quarter, indicating a fall of 13% from the year-ago reported figure.Factors at PlayDenbury Resources has a relatively low-risk business model as it produces oil by applying tertiary recovery techniques in mature fields. In this regard, its Cedar Creek Anticline and Tinsley Field Cotton Valley properties are expected to have created promising exploiting opportunities, which will be reflected in the to-be-reported quarter.The company has an oil-heavy portfolio (comprising 97.3% of the total volume in the last reported quarter). Hence, changes in crude price will affect its bottom line. Notably, West Texas Intermediate (WTI) crude price in first-quarter 2019 was lower than the year-ago period. In January, February and March, WTI averaged $51.38, $54.95 and $58.15 per barrel, respectively, per the U.S. Energy Information Administration. In comparison, WTI averaged $63.70, $62.23 and $62.73 per barrel, respectively, in the first three months of 2018. Lower oil price realization will likely hurt the company’s first-quarter 2019 results. In such a situation, quarterly earnings are likely to fall 33.3% on a year-over-year basis.What Our Model UnveilsOur proven model does not conclusively show that Denbury Resources is likely to beat the Zacks Consensus Estimate in the quarter to be reported.
