Effect of Sustainability Reporting on Financial Performance of Quoted Pharmaceutical Companies in Nigeria

The thrust of this study was to ascertain the effect of sustainability reporting on financial performance of quoted pharmaceutical companies in Nigeria for a period of ten (10) years spanning from 2012 to 2021. Ex-post facto and longitudinal research design was adopted. Sustainability disclosure which is the independent variable was captured using employee health and safety disclosure, social disclosure, environmental disclosure, and governance disclosure while financial performance which served as the dependent variable was measured using return on investment (ROI). Panel data were obtained from annual reports and accounts of the sampled health care companies and subjected to preliminary data tests such as descriptive analysis, correlation analysis, variance inflation factor analysis and hausman effects tests for the study period. Multiple panels least regression analysis was employed via E-Views 12. The results of the tested hypotheses revealed that employee health and safety disclosure, and social disclosure have positive and significant effect on financial performance of health care companies in Nigeria which was statistically significant at 95% confidence level respectively while a negative but insignificant effect was documented against environmental disclosure, governance disclosure and financial performance of health care companies in Nigeria. In conclusion, the findings shed light on the substitute and complementary relationship between performance and the increase in sustainability disclosure quality.
