Corporate social responsibility disclosure (CSRD) has gained prominence due to growing stakeholders’ expectations for transparency and accountability in companies. This study, therefore, investigates the effect of corporate social responsibility disclosure on economic value added of financial services firms listed in Nigeria. A longitudinal research design was used on data obtained from companies with a population of forty-nine (49) firms publicly listed in financial services in Nigeria as at 31st December 2025, whose audited financial statements were available from 2013 to 2015. The total population was also purposely selected as the sample. The results revealed that the education initiative (EIND) and community responsibility disclosure (CMRD) have a negative effect on ECVA; EIND was not statistically significant, whereas CMRD was. However, there is an affirmative and statistically insignificant effect of health and safety disclosure (HSFD) on the economic value added of sample firms. In consonance with the results, this study recommends that corporate managers and directors align corporate responsibility with the host community's expectations to meet needs and enhance their reputation, thereby improving economic value.
