This research paper conducts a comprehensive profitability analysis of Reliance Industries Ltd. over a five-year period (2019-2024). Key financial metrics, including Gross Profit Margin (GPM), Net Profit Margin (NPM), Operating Profit Margin (OPM), Return on Assets (ROA), Return on Equity (ROE), Return on Capital Employed (ROCE), and Earnings Per Share (EPS), are examined to evaluate the company’s financial performance and efficiency. The findings reveal robust profitability, with an average GPM of 66.94% and steady growth in EPS, which peaked at Rs. 12.45 in 2023-24. However, fluctuations in NPM, OPM, ROE, and ROCE indicate challenges in maintaining peak efficiency and profitability. Notably, the ROA demonstrated stability, reflecting effective resource management. The study highlights the importance of consistent cost control, strategic capital utilization, and operational improvements in sustaining profitability and shareholder value. Despite periodic declines in some metrics, Reliance Industries Ltd. showcases strong overall financial performance, underscoring its resilience and market leadership. This analysis provides actionable insights for stakeholders to enhance decision-making and ensures sustained financial growth in a dynamic business environment.
