This study aims to analyze the effect of sustainability reporting and operational efficiency on firm value in manufacturing companies within the consumer non-cyclicals sub-sector listed on the Indonesia Stock Exchange (IDX) during the 2020–2024 period. This study employs a quantitative approach using secondary data obtained from companies’ annual reports and sustainability reports. The research sample was selected using a purposive sampling method, resulting in a number of firms that met the research criteria. The analytical method used is panel data regression by incorporating control variables in the form of firm size and leverage to control the influence of other factors on firm value. Firm value is measured using Tobin’s Q, sustainability reporting is measured based on the GRI disclosure index, and operational efficiency is measured using net profit margin. The results indicate that sustainability reporting and operational efficiency have an effect on firm value. Simultaneously, both independent variables play a role in increasing firm value. The findings of this study are expected to contribute to companies in improving the quality of sustainability disclosure and the management of operational efficiency, as well as to serve as a consideration for investors in making investment decisions.
