Despite the growing literature on corporate social responsibility (CSR), little is known about how the board of directors' competence can affect the CSR‐financial performance relationship during severe uncertainties such as the COVID‐19 outbreak. This paper focuses on exploring the mediating role of CSR in the connection between board competence and corporate financial performance amidst global uncertainties. The sample consists of Jordanian companies listed on the Amman Stock Exchange. Data were analyzed using the partial least square structural equation modeling. The findings show that boards' CSR competence has a direct and indirect positive impact on financial performance. Therefore, boards of directors' CSR competence can be seen as enablers for CSR activities. In this regard, companies could invest more in qualifying board directors to be socially responsible and enhance their role in improving corporate financial performance. This study identifies and provides empirical evidence on a critical enabler of CSR activities (i.e., boards of directors' CSR competence) from a developing country perspective. This, in turn, could widen the management and other stakeholders' understanding of CSR‐enhancing factors and therefore increase its efficiency. We provide theoretical and practical implications to guide regulators and businesses to ensure sustainable development.
