This study investigates whether supply chain sustainability risks, which manifest whenever a buying firm is held accountable for the irresponsible behaviour of its suppliers, subsequently affect the financial performance of the buyer. Utilizing event study methodology on a secondary dataset of 392 firms and 2,814 media announcements, we provide evidence that suppliers’ environmental, social, and governance misconducts cause negative stock price reactions for the buying firms. We find that negative abnormal stock returns are higher for SCSR announced by more powerful media outlets and SCSR associated with firms operating in countries and industries where sustainable behaviour is not expected.
