Investors are always looking for stocks that are poised to beat at earnings season and Proterra Inc. 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 Proterra 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 PTRA in this report.

In fact, the Most Accurate Estimate for the current quarter is currently at a loss of 15 cents per share for PTRA, narrower than the broader Zacks Consensus Estimate of a loss of 17 cents per share. This suggests that analysts have very recently bumped up their estimates for PTRA, giving the stock a Zacks Earnings ESP of +9.09% heading into earnings season.

Why is this Important?

A positive reading for the Zacks Earnings ESP has proven to be very powerful in producing both positive surprises, and outperforming the market. Our recent 10-year backtest shows that stocks that have a positive Earnings ESP and a Zacks Rank #3 (Hold) or better show a positive surprise nearly 70% of the time, and have returned over 28% on average in annual returns (see more Top Earnings ESP stocks here).

Given that PTRA has a Zacks Rank #3 and an ESP in positive territory, investors might want to consider this stock ahead of earnings. You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

Clearly, recent earnings estimate revisions suggest that good things are ahead for Proterra, and that a beat might be in the cards for the upcoming report.
