Acquisitions and the cost of debt: Evidence from China

A large body of literature has examined the effect of mergers and acquisitions (M&As) on firm valuation, and generally find that M&As reduce acquirers' shareholder value. However, relatively little is known about the effect of M&As on the pricing of corporate debt by debtholders, especially for firms in less developed countries. Using a sample of Chinese listed firms with outstanding bonds from 2007 to 2020, we find that the cost of debt is lower for acquirers than for non-acquirers, and that the effect of acquisitions in reducing cost of debt is more pronounced for firms from provinces with less developed markets, for private firms, and for firms undertaking cross-province acquisitions. Our results are robust to a series of robustness checks that address various endogeneity concerns, including the use of a matched-sample approach, the use of the Heckman two-stage model and a change analysis, the control for acquirers' pre-acquisition bond yield spread, and the exclusion of acquisitions of publicly listed targets. Our analyses of provincial institutional factors show that the relationship between M&As and cost of debt is moderated by government relations to market, private economy development, and the development of market intermediaries and legal environment. We further document that acquirers have lower default risk during the post-acquisition period because of a coinsurance effect, and that acquirers attract more analyst following and investors after acquisitions. Overall, our results indicate that acquisitions can reduce cost of debt through reducing firms' default risk and information risk, and that institutional factors matter for the effect of M&As on the cost of debt.
