The estimated EPS of $0.79 sets a benchmark for Columbia Banking System's upcoming earnings report. Given the stock's decline over the past year and mixed reactions to past earnings, the short-term impact is uncertain. The market will likely focus on whether COLB beats the EPS estimate and provides positive guidance, which could influence the stock price. However, the historical data shows that even an earnings beat may not necessarily lead to a positive stock price movement, hence the neutral score.
