The question of the balance between corporate sustainability initiatives and profitability has been widely discussed. The problems facing today's managers were how to manage performance across sustainable dimensions so that the synergistic advantages of its execution approach may be derived. Hence, the study examines social and environmental impact on financial-performance twenty-four (24) listed manufacturing firms in Nigeria from 2010 to 2020. Secondary data and multiple-regression technique were adopted. The variables for the study are community relations, research and development and return-on-assets. Finding revealed that R&D cost has positive significant outcome on firm accomplishment as these items show-up in the fixed effects regression with statistically significant p-values. Likewise, Finding revealed that community cost has negative non-significant effect on firm accomplishment. The study concluded that investment in research and development should be deployed more to increase the financial performance of manufacturing firms while community relations cost should be embark upon but more funds should not be committed to it. It is therefore recommended that shareholders and regulatory authorities should ensure compliance with regulations in providing environmental-information as this will help firms to be conscious of the environment they belong.
