We examine the impact of corporate social responsibility (CSR) on mergers and acquisitions (M&A) target choices. We offer evidence that CSR performance of firms matter for M&A acquirers. Indeed, our results based on 608 deals between 2003 and 2014 reveal that target firms have on average higher CSR scores than similar non-target firms. We also show directly that a firm's CSR is positively associated with its propensity to become a M&A target. These results hold for all CSR dimensions (environment, social, and governance). Overall, our results suggest that CSR matters in M&A decisions.
