We examine the causal effect of managerial litigation risk on managers’ disclosure of earnings warnings in the face of large earnings shortfalls. Exploring the staggered adoption of universal demand (UD) laws as an exogenous decrease in litigation risk, we find that the adoption leads to a decrease in managers’ issuance of earnings warnings, especially among firms facing a higher litigation risk prior to the adoption. In contrast, we find no change in managers’ tendency to alert investors of impending large positive earnings surprises. Collectively, our results provide causal evidence that higher litigation risk incentivizes managers to issue more earnings warnings. Our results differ from Bourveau et al.’s finding of an increase in the frequency of management earnings forecasts after the adoption of UD laws. We reconcile our findings with theirs by demonstrating that the effect of adopting UD laws on management earnings forecasts depends critically on forecast horizon: The adoption increases long‐horizon forecasts, but decreases short‐horizon forecasts.

This study examines the association between customer base concentration and corporate public disclosure policy. When the customer base is more concentrated, large customers face lower costs of accessing the supplier firm's private information, reducing customers' overall demand for the supplier's public information, suggesting a negative association between customer concentration and the amount of public disclosure. Alternatively, large customers have greater bargaining power and may demand that the supplier firm provide more public disclosures. Consistent with customer concentration facilitating private information flow from the supplier to customers, we find that the frequencies of management earnings and sales forecasts are negatively associated with customer concentration among firms with major corporate customers. These associations are stronger when the supplier and customers are engaged in more relationship‐specific investments, when customers' private information acquisition costs are lower, and when it is less costly for customers to find another supplier.
