Amidst the growing emphasis on sustainable development, there is an emerging trend of companies actively pursuing the transition towards sustainability. This shift is driven by various factors, including heightened societal scrutiny and a greater focus on environmental, social, and governance (ESG) considerations. As a result, companies are increasingly acknowledging the significance of incorporating sustainable practices into their operations to align with the expectations of the capital market. This paper investigates the association between ESG disclosures and stock price crash moderated by corporate governance (board size, independence, and gender diversity) for Saudi firms. Using a fixed effects regression method, we find that the coefficient of ESG is significant and negative (−0.0043 for NCSKEW and − 0.0006 for DUVOL) indicating a positive influence of ESG in diminishing stock price crash. The results also show that corporate governance positively and significantly moderate the ESG‐stock price crash risk. As additional analyses, we find a significant negative relationship between each aspect of ESG including social responsibility, environmental activities and governance practices and stock price crash risk. Moreover, the pandemic COVID‐19 has a dampening effect on the ESG‐stock price crash association. To ensure the validity of these conclusions, dynamic GMM models were employed to tackle any potential endogeneity issues, making the results even more robust. Our findings highlight that improving corporate sustainability positively impacts the stability of companies' stock prices. This study provides valuable insights and perspectives from the context of Saudi Arabia and offers theoretical and managerial implications that are relevant for policymakers and investors.
