This research paper investigates the dynamic interplay between financial leverage and the performance enhancement in Omani companies, specifically those listed on the Muscat Stock Exchange. Employing a panel data analysis approach, the study utilizes secondary data extracted from the financial statements of selected listed companies covering the period from 2018 to 2022. The research specifically integrates three pivotal ratios—Solvency Ratio, Debt-to-Equity Ratio, and Proprietary Ratio—to systematically analyze their respective impacts on Return on Assets (ROA) and Return on Equity (ROE). Grounded in a thorough analysis of company data, this study not only offers insightful analyses of historical financial information but also integrates growth performance predictions by the researcher. These predictions aim to identify positive or negative correlations between financial leverage and overall corporate performance. The study's findings hold significant implications for strategic decision-making, capital structure optimization, and advancing the understanding of financial dynamics in the Omani business landscape.
