This study aims to investigate the effect of analyst coverage on the relationship between IR activity and earnings quality. The main findings of the analysis are as follows. First, firms that hold IR events tend to engage in earnings management through discretionary accruals, and the stock price informativeness of future earnings is lower. This indicates relatively lower earnings quality. Second, firms covered by analysts tend to engage more in earnings management. This supports prior research suggesting that analyst coverage may serve as a source of performance pressure. However, the incremental current and future earnings response coefficients of firms covered by analysts are both significantly positive. This implies that despite higher earnings management, the stock price informativeness of both current and future earnings is greater for firms covered by analysts. Third, the combined effect of IR activity and analyst coverage on earnings management and earnings response coefficients, including ERC and FERC, is limited or statistically insignificant. This suggests that analyst coverage has only a limited moderating role in the relationship between IR activity and earnings quality. Instead, it implies that analyst coverage may serve as a main factor in assessing earnings quality, more so than the mere presence of IR activities.
