Harte-Hanks missed its Q3 earnings estimates significantly, reporting an EPS of $0.08 versus an estimate of $0.18. This is a negative signal for investors and could lead to a decrease in the company's share price. Additionally, the company's revenue was down $6.77 million from the same period last year, which could further negatively impact the stock. The company's past performance shows a pattern of missing earnings estimates, which was followed by a drop in share price.
