<![CDATA[Abstract: This study aims to analyze the simultaneous and partial effects of Return on Assets (ROA), Gross Profit Margin (GPM), and Net Profit Margin (NPM) on Stock Prices in Mining Companies Listed on the Indonesia Stock Exchange (IDX). The data used are secondary data. The sample consisted of 25 companies during the 2023–2025 period, resulting in 75 observations. The research employed a quantitative method using multiple linear regression analysis. The results of the F-test showed that ROA, GPM, and NPM simultaneously have a significant effect on Stock Prices with an Fcount value of 3.821 > Ftable 2.73. The results of the t-test showed that ROA has a positive and significant effect on Stock Prices with a tcount value of 2.979 > ttable 1.99346. GPM does not have a significant effect on Stock Prices with a -tcount value of -1.643 > -ttable -1.99346. Meanwhile, NPM has a positive and significant effect on Stock Prices with a tcount value of 2.227 > ttable 1.99346. The Adjusted R Square value is 0.103, which means that 10.3% of the variation in Stock Prices can be explained by ROA, GPM, and NPM, while the remaining 89.7% is influenced by other variables outside the research model.
