Earnings are arguably the most important single number on a company's quarterly financial report. Wall Street clearly dives into all of the other metrics and management's input, but the EPS figure helps cut through all the noise.

The earnings figure itself is key, of course, but a beat or miss on the bottom line can sometimes be just as, if not more, important. Therefore, investors should consider paying close attention to these earnings surprises, as a big beat can help a stock climb and vice versa.

Hunting for 'earnings whispers' or companies poised to beat their quarterly earnings estimates is a somewhat common practice. But that doesn't make it easy. One way that has been proven to work is by using the Zacks Earnings ESP tool.

The Zacks Earnings ESP, Explained

The Zacks Earnings ESP, or Expected Surprise Prediction, aims to find earnings surprises by focusing on the most recent analyst revisions. The basic premise is that if an analyst reevaluates their earnings estimate ahead of an earnings release, it means they likely have new information that could possibly be more accurate.

Now that we understand the basic idea, let's look at how the Expected Surprise Prediction works. The ESP is calculated by comparing the Most Accurate Estimate to the Zacks Consensus Estimate, with the percentage difference between the two giving us the Zacks ESP figure.

Bringing together a positive earnings ESP alongside a Zacks Rank #3 (Hold) or better has helped stocks report a positive earnings surprise 70% of the time. Furthermore, by using these parameters, investors have seen 28.3% annual returns on average, according to our 10 year backtest.

Most stocks, about 60%, fall into the #3 (Hold) category, and they are expected to perform in-line with the broader market. Stocks with a #2 (Buy) and #1 (Strong Buy) rating, or the top 15% and top 5% of stocks, respectively, should outperform the market, with Strong Buy stocks outperforming more than any other rank.

Should You Consider Western Union?

The final step today is to look at a stock that meets our ESP qualifications. Western Union (WU Quick QuoteWU - Free Report) earns a #3 (Hold) 12 days from its next quarterly earnings release on February 3, 2026, and its Most Accurate Estimate comes in at $0.44 a share.

By taking the percentage difference between the $0.44 Most Accurate Estimate and the $0.43 Zacks Consensus Estimate, Western Union has an Earnings ESP of +1.51%. Investors should also know that WU is one of a large group of stocks with positive ESPs. Make sure to utilize our Earnings ESP Filter to uncover the best stocks to buy or sell before they've reported.

WU is one of just a large database of Business Services stocks with positive ESPs. Another solid-looking stock is Booz Allen Hamilton (BAH Quick QuoteBAH - Free Report) .

Slated to report earnings on January 23, 2026, Booz Allen Hamilton holds a #2 (Buy) ranking on the Zacks Rank, and its Most Accurate Estimate is $1.31 a share one day from its next quarterly update.

The Zacks Consensus Estimate for Booz Allen Hamilton is $1.26, and when you take the percentage difference between that number and its Most Accurate Estimate, you get the Earnings ESP figure of +4.18%.

Because both stocks hold a positive Earnings ESP, WU and BAH could potentially post earnings beats in their next reports.
