The study investigated the determinants of financial performance in Tropical Bank Limited, located along Kampala Road, Kampala, Uganda. The research sought to understand how capital adequacy, liquidity, credit risk, and operational efficiency influenced the bank's overall financial performance over a five-year period spanning 2018 to 2022. A quantitative research design was adopted, and data were collected from the bank's audited annual financial reports and statements. Multiple regression analysis was used to establish the nature and strength of the relationships between the independent variables and the dependent variable, which was measured using Return on Assets (ROA). The results revealed that capital adequacy and operational efficiency were the strongest and most statistically significant predictors of financial performance, with p-values of 0.003 and 0.008, respectively. Liquidity demonstrated a moderate positive relationship with financial performance (p = 0.041), while credit risk showed a negative but statistically significant association (p = 0.012). The study concluded that Tropical Bank Limited's financial performance was primarily driven by the strength of its capital base and the efficiency with which it managed its dayto-day operational costs. It was recommended that the bank's management prioritizes capital strengthening strategies, adopt more rigorous credit risk assessment frameworks, and invest in operational technologies capable of reducing overhead costs. Future researchers were encouraged to explore additional determinants such as macroeconomic variables and corporate governance structures.
