The upcoming earnings release is a significant event for AZZ Inc. and its investors. The company's past performance shows a mixed trend of beating and missing EPS estimates, which has led to varying stock price changes. However, the company's shares have been performing well over the past year, which could indicate investor confidence in the company's performance. The actual impact on the stock price will depend on whether the company meets, exceeds, or falls short of the EPS estimate and the guidance it provides for future quarters.
