Disclosure of strategic collaborative agreements and the cost of equity capital

How corporate strategic disclosure affects investor evaluations is a crucial and widely discussed question. Although prior literature has spent efforts analyzing the information effect of strategic alliances on investor reactions, whether this effect can extend to the cost of equity capital still needs to be explored. Using data from China's A-share listed firms from 2007 to 2021, we examine the impact of disclosing strategic collaborative agreements on equity capital costs. We find that disclosing strategic collaborative agreements relates to lower equity capital costs. These results hold after several robustness checks. The mechanism test reveals that announcing strategic collaborative agreements alleviates equity capital costs mainly through the information effect. Moreover, this effect is more salient in firms with lower agency costs, lower media coverage, positive media sentiment, and higher media quality. These findings suggest that strategic collaborative agreements provide investors with valuable information.
