ESS Tech, Inc. (GWH) is expected to deliver a year-over-year increase in earnings on higher revenues when it reports results for the quarter ended June 2024. This widely-known consensus outlook gives a good sense of the company's earnings picture, but how the actual results compare to these estimates is a powerful factor that could impact its near-term stock price.

The earnings report, which is expected to be released on August 14, 2024, might help the stock move higher if these key numbers are better than expectations. On the other hand, if they miss, the stock may move lower.

While management's discussion of business conditions on the earnings call will mostly determine the sustainability of the immediate price change and future earnings expectations, it's worth having a handicapping insight into the odds of a positive EPS surprise.

Zacks Consensus Estimate

This company is expected to post quarterly loss of $0.11 per share in its upcoming report, which represents a year-over-year change of +26.7%.

Revenues are expected to be $3.24 million, up 14.5% from the year-ago quarter.

Estimate Revisions Trend

The consensus EPS estimate for the quarter has been revised 5.35% lower over the last 30 days to the current level. This is essentially a reflection of how the covering analysts have collectively reassessed their initial estimates over this period.

Investors should keep in mind that an aggregate change may not always reflect the direction of estimate revisions by each of the covering analysts.

Earnings Whisper

Estimate revisions ahead of a company's earnings release offer clues to the business conditions for the period whose results are coming out. This insight is at the core of our proprietary surprise prediction model -- the Zacks Earnings ESP (Expected Surprise Prediction).

The Zacks Earnings ESP compares the Most Accurate Estimate to the Zacks Consensus Estimate for the quarter; the Most Accurate Estimate is a more recent version of the Zacks Consensus EPS estimate. The idea here is that analysts revising their estimates right before an earnings release have the latest information, which could potentially be more accurate than what they and others contributing to the consensus had predicted earlier.

Thus, a positive or negative Earnings ESP reading theoretically indicates the likely deviation of the actual earnings from the consensus estimate. However, the model's predictive power is significant for positive ESP readings only.

A positive Earnings ESP is a strong predictor of an earnings beat, particularly when combined with a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold). Our research shows that stocks with this combination produce a positive surprise nearly 70% of the time, and a solid Zacks Rank actually increases the predictive power of Earnings ESP.
