Abstract
This study examined the impact of corporate governance on the financial performance of publicly traded Deposit Money Banks (DMBs) in Nigeria. The objective was to determine whether board size, female board membership, and board independence affect the financial performance of these banks. The study covered five DMBs from 2013 to 2023.Findings revealed that board independence significantly impacts financial performance but has a negative relationship with it. Board size also has a negative relationship with financial performance, though it remains significant. Female board membership shows a positive relationship with financial performance, but this effect is not statistically significant. The study recommends that mechanisms related to board independence, board size, and female board membership are critical components of corporate governance for achieving organizational objectives.
