This paper examines the impact of corporate governance practices on the profitability of manufacturing firms in Nigeria to evaluate the impact of board composition and ownership structure on the financial performance of Yale Foods PLC. The Expo facto research design was used. The study Population was Yale Foods staff. The findings shows that established institutional ownership has a significant effect on firm profitability level from time to time, as large investors demand accountability and discourage mismanagement. Based on the findings, manufacturing firms in Nigeria should strengthen their board structures by ensuring an optimal mix of executive and non-executive directors and promoting gender and professional diversity for effective decision-making. Second, companies should encourage greater institutional ownership because institutional investors enhance monitoring and reduce the risk of managerial opportunism.1
