This study investigates the influence of Environmental, Social, and Governance (ESG) factors on the financial performance of publicly traded U.S. companies between 2013 and 2023. Using a balanced panel dataset of 386 S&P 500 firms and 4246 firm-year observations, the analysis applies panel data regression models with fixed effects to evaluate the association between ESG scores and two financial indicators: Return on Assets (ROA) and Tobin’s Q. The results reveal a modest association with ROA, but a significantly stronger link with Tobin’s Q, suggesting that while ESG practices may not substantially boost short-term profitability, they are positively perceived by investors and contribute to long-term market value. These findings are consistent with stakeholder and signalling theories, indicating that strong ESG performance reflects effective management and lower investment risk. The limited impact on ROA may stem from the initial costs of implementing ESG initiatives. This study highlights practical implications for corporate leaders and policy-makers, advocating for ESG integration as a long-term value driver. Future research should explore alternative ESG rating systems and consider sectoral dynamics and broader market influences.
