Bandung, West Java – The Effect of ESG Disclosure, Capital Structure, and Company Size on Company Value with Company Age as a Moderation Variable (Study on IDX ESG Leaders in 2020–2024). This research was conducted by Ridha Annas Fat-h Sabila and Desmiza from Jenderal Achmad Yani University in a scientific article published in the East Asian Journal of Multidisciplinary Research (EAJMR) in 2026.

Research conducted by Ridha Annas Fat-h Sabila and Desmiza revealed that the disclosure of Environmental, Social, and Governance (ESG) and the high use of debt do not necessarily increase the company's value in the eyes of investors. In fact, in a number of cases, the two are negatively correlated with the company's value as measured using Tobin's Q ratio.

ESG Is Popular, But Markets Haven't Fully Appreciated

In recent years, ESG-based investments have grown rapidly as the number of investors in the Indonesian capital market has increased. IDX ESG Leaders even recorded a relatively superior performance of the index compared to other ESG indices.

However, research data shows that there is a mismatch between ESG performance and market valuation. Although ESG disclosure is increasing, company value does not automatically increase.

This study analyzed 12 companies that were consistently listed in the IDX ESG Leaders during 2020–2024. Data was obtained from the company's financial statements and sustainability reports, then analyzed using panel data regression and Moderated Regression Analysis (MRA).

Three Key Research Findings

Based on the results of the analysis, there are several important findings:

  1. ESG disclosure has a negative effect on company value (Tobin's Q).
    Investors are considered not to fully see ESG as a factor that directly increases market valuation.
  2. The debt-to-equity ratio (DER) capital structure also has a negative impact.
    The average DER of companies in the sample reached 260.1 percent, indicating a high dependence on debt and increasing the perception of financial risk.
  3. The size of the company has a positive effect on the value of the company.
    Companies with total large assets—an average of IDR 506.64 trillion—are seen as more stable and trusted by investors.

The age of the company is not decisive

The study also examined whether the age of a company strengthens the relationship between ESG, capital structure, and company size to company value. The results show that the age of the company actually weakens the influence of these three variables.

This means that investors in the Indonesian capital market are more focused on actual performance and long-term prospects than the length of time the company has been established. Companies that are decades old do not automatically get a higher rating if their financial performance and risk management are not optimal.

Why is ESG Rated Negatively?

According to researchers, this condition can occur because ESG disclosure has not been carried out comprehensively and has not been able to clearly show long-term economic benefits to investors.

The cost of ESG implementation is considered a burden if it is not offset by improved performance or effective communication to the market. Investors are still prioritizing financial stability, operational efficiency, and risk management. In other words, ESG has not yet fully become the main factor in the formation of corporate value in Indonesia, especially in the 2020–2024 research period.

Implications for the Business World and Investors

The results of this study provide several strategic messages:

  1.  Companies need to improve the quality and transparency of ESG disclosures so that their long-term benefits can be understood by investors.
  2. The management of the capital structure must be maintained so that it is not too aggressive in the use of debt.
  3. Asset size and operational stability remain key factors in building market confidence.
  4. Investors should not only look at ESG labels, but also evaluate debt risk and asset management efficiency.

This research reinforces the view that the value of companies in the Indonesian capital market is still heavily influenced by traditional fundamental factors rather than formal sustainability indicators.
