The purpose of this study is to examine the relationship between sustainability performance (SP) and financial performance (FP), based on performance disclosures (reporting) of the Jordanian financial sector for the period of 2017–2020. The study employs green innovation (GI) indicators as moderating and mediating variables; by using hierarchical regression; as means of unlocking and examining the relationship between SP and FP; through the lens of the stakeholder theory. The hierarchical regression findings suggest that GI indicators partially mediate the relationship between SP and FP, but do not demonstrate a moderating effect. As a main result, it is indicated that Jordanian financial institutions may use SP transparency indicators as an incentive variable, which could influence their overall FP. The research also contributes to the existing literature by adding insight into the use of GI indicators in a developing country and the potential impact on financial institutions markets. These findings lend empirical credence to the generally held belief that increase disclosure benefits for both internal and external users.
