Investors are always looking for stocks that are poised to beat at earnings season and Heartland BancCorp HLAN may be one such company. The firm has earnings coming up pretty soon, and events are shaping up quite nicely for their report.That is because Heartland is seeing favorable earnings estimate revision activity as of late, which is generally a precursor to an earnings beat. After all, analysts raising estimates right before earnings — with the most up-to-date information possible — is a pretty good indicator of some favorable trends underneath the surface for HLAN in this report.In fact, the Most Accurate Estimate for the current quarter is currently at $2.22 per share for HLAN, compared to a broader Zacks Consensus Estimate of $2.03 per share. This suggests that analysts have very recently bumped up their estimates for HLAN, giving the stock a Zacks Earnings ESP of +9.63% heading into earnings season.Heartland BancCorp.
