Abstract: This study aims to examine the effect of sustainability reports and financial performance on firm value, with dividend policy as a mediating variable. The population in this study consists of companies listed on the LQ45 index, with samples selected using purposive sampling techniques, resulting in 21 companies during the five-year observation period . Data analysis was conducted using path analysis. The results of the study indicate that sustainability reports do not influence dividend policy and have a negative effect on firm value. Additionally, dividend policy does not mediate the relationship between sustainability reports and firm value. Conversely, financial performance has a positive effect on dividend policy and firm value. Dividend policy is also found to mediate the influence of financial performance on firm value. Keywords: Firm Value. Sustainability Report Disclosure. Financial Performance. Dividend Policy. INTRODUCTION Companies have several objectives, including generating profits, increasing shareholder wealth, and enhancing firm value (Widiastuti et al. , 2. Investors and company management must be able to work together to increase the value of the firm (Fajri & Munandar, 2. Firm value is an important indicator for investors when considering investment decisions. Increasing firm value aims to attract investors to invest (Hermawaty & Sudana 2. Prospective investors will view the firm as healthy and of high value, reflecting the firm's good performance (Ompusunggu & Wijaya, 2. A high firm value generally means that the firm is competitive, has good profitability, and promising growth prospects (Tambunan, 2. Sustainability reporting is the practice of measuring, disclosing and ensuring accountability for an organisation's performance in achieving sustainable development goals to both internal and external stakeholders (Yulia et al. , 2. The standard commonly used in preparing sustainability reports is the GRI Standard (Silvana & Khomsyiah, 2. 4139 | P a g e https://dinastipub. org/DIJEFA Vol. No. 5, 2025 Sustainability reporting using GRI Standards guidelines aims to ensure transparency regarding how organisations contribute to sustainable development. GRI Standards are used to evaluate the quality of sustainability reports, assessing how comprehensive they are. The more information a company discloses, the better its sustainability report (Suharyani et al. , 2. Financial performance is a description of the financial condition of an entity analysed using financial analysis tools, so that the financial condition of the entity can be seen, showing its performance during a certain period (Marthadevi & Mimba, 2. Financial performance reflects the success of a firm in its operations and resource management. ROA shows how efficiently a firm uses its assets to generate profits (Sumarna, 2. A high ROA value sends a positive signal to investors that the company is capable of generating profits efficiently. This attracts investors to buy the company's shares, which ultimately drives up the share price and increases the value of the company (Merllizcha & Triyonowati, 2. Dividend policy is a decision on whether the profits earned by a company will be distributed to shareholders in the form of dividends or retained to increase capital for future investment financing (Narayanti & Gayatri 2. An indicator of dividend policy is the Dividend Payout Ratio (DPR). A high DPR indicates that the company is more focused on profit distribution, while a low DPR indicates a greater allocation of profits for growth (Sherly & Edastami 2. Signal theory explains that high-quality companies will send signals to the market through transparent financial disclosures. This information can serve as a signal for investors and other parties in making economic decisions (Rahayu 2. Companies can trigger positive reactions from the market and investors. If the information has a negative impact, the information in the annual report can influence investor decisions (Najiyah & Lahaya, 2. The stakeholder theory explains that companies, in conducting their operational activities, should not only act in the interests of shareholders, but should also involve several parties that are directly or indirectly affected by the firm's operational results (Sari & Budiasih. The firm must have a positive impact on stakeholders. This is done to provide a positive impact on stakeholders, so that the firm can gain support and insight from stakeholders that can increase the value of the firm (Putri & Mutumanikam, 2. There are differences of opinion found by previous researchers. Research by Chen et al. and Matos et al. , . explains that sustainability reports have a positive influence on dividend policy, while research by Supriyadi et al. explains that sustainability reports have no influence on dividend policy. Research by Meirawati et al. Prasetyoningrum et al. and Zakaria . explains that dividend policy has an impact on dividend policy. Meanwhile, research by Erawati et al. explains that financial performance does not have an impact on dividend policy. Research by Sevnia & Mulyani . shows that sustainability report disclosure sends a positive signal to investors, while research by Afifah & Irawan . Amin et al. and Susianto & Wirakusuma . states that Indonesian investors remain more focused on financial gains. Febriana et al. ,Mukhita et al. , and Novianti et . found that financial performance measured by ROA has a significant effect on company value, while research by Aditia et al. and Saragih et al. explains that financial performance measured by ROA does not affect company value. Research by Kusumawati et al. Seth & Mahenthiran . and Setiawati . explains that dividend policy affects company value, while research by Tiari & Adiputra . Rahma & Arifin . , and Safitri et al. explain that dividend policy does not affect company The disclosure of sustainability reports provides ESG information that can enhance a company's reputation and risk management. This encourages companies to implement sustainable dividend policies as a form of responsibility to stakeholders. Based on stakeholder 4140 | P a g e https://dinastipub. org/DIJEFA Vol. No. 5, 2025 theory, companies adjust their dividend policies to meet social and environmental expectations. This is supported by research from Barros et al. Chen et al. Matos et al. H1: The disclosure of sustainability reports has a positive effect on dividend policy. Good financial performance indicates efficient use of assets and high profitability. Companies that are able to generate profits tend to pay dividends as a positive signal to Signal theory explains that dividends serve as an indicator of confidence in a company's financial prospects. This is supported by research conducted by Meirawati et al. Prasetyoningrum et al. , and Zakaria . H2: Financial performance has a positive effect on dividend policy. Sustainability reports reflect transparency and accountability for a company's social and environmental impact. These reports increase public trust and strengthen relationships with Stakeholder theory asserts that this can enhance a company's reputation and This research is supported by Annisa et al. Karya & Mimba . , and Sevnia et al. H3: Sustainability reports have a positive impact on firm value. Good financial performance sends a positive signal about the company's prospects and ROA as a performance indicator shows effectiveness in generating profits. According to signal theory, this information increases investor confidence and has an impact on company This research is supported by Febriana et al. and Novianti et al. H4: Financial performance has a positive effect on firm value. Dividend policy is a tool for companies to communicate with investors about their financial prospects. Stable dividends indicate management's confidence in good financial This strengthens the firm's value by increasing positive perceptions in the market. This research is supported by Kusumawati et al. and Seth & Mahenthiran . H5: Dividend policy has a positive effect on firm value Sustainability reports enhance a company's reputation and accountability, while dividend policies reinforce positive signals to investors. These two factors complement each other in building market confidence. Signal theory and stakeholder theory suggest that dividends serve as a mediating mechanism for increasing firm value. This research is supported by Akhmadi & Januarsi . Gharbi & Jarboui . , and Morieta et al. H6: dividend policy mediates sustainability report on firm value Financial performance reflects a company's ability to generate profits, while dividend policy shows how those profits are distributed. This combination sends a positive signal about the company's prospects to investors. Dividends are an important intermediary in strengthening the influence of ROA on firm value. This research is supported by studies conducted by Idrus & Anwar . and Lestari, . H7: dividend policy mediates financial performance on firm value METHOD This study focuses on companies listed on the LQ45 Index from 2019 to 2023 by accessing financial reports, annual reports, and sustainability reports on the official website of the Indonesia Stock Exchange (IDX) or the official websites of each company. The object of this study is firm value, which is measured through sustainability report disclosure, financial performance, and dividend policy. This study uses a quantitative approach with secondary data 4141 | P a g e https://dinastipub. org/DIJEFA Vol. No. 5, 2025 in the form of financial statements, annual reports, and sustainability reports. The research population consists of 45 companies listed on the LQ45 Index, and purposive sampling was used to determine the sample, resulting in 21 companies with a total of 105 observations. Firm value is a market ratio used to measure the performance of a stock's market price relative to its book value (Firmansyah et al. , 2. The Price to Book Value (PBV) ratio is used to compare a company's stock price with its book value (Anggreni et al. PBV can provide an indication of how much the market values a company's book value. If PBV is high, it means that market confidence in the company's prospects is also high (Saddam et al. , 2. ycycycuycayco ycyycycnycayce Price to Book Value (PBV) = . ycaycuycuyco ycycaycoycyce ycyyceyc ycEaycaycyce Sustainability Report is a measurable report published by a company regarding the economic, social, and environmental impacts of its activities, with the aim of fostering economic prosperity without harming the environment (Madani & Gayatri, 2. The calculation method for sustainability report disclosure can be measured using the Sustainability Report Disclosure Index (SRDI) (Dewi & Putri, 2. The SRDI measurement assigns a value of 1 if an item is disclosed and a value of 0 if it is not disclosed, based on the SRDI calculation. From this, the authors obtained the total score for each item from each company (Amin et al. SRDI = ycuycycoycayceyc ycuyce yccycnycycaycoycuycycycyceyc ycuycycoycayceyc ycuyce yccycnycycaycoycuycycycyceyc yceycuycyyceycaycyceycc y 100 % . Financial performance is an analysis conducted to measure the extent to which a company has successfully managed its finances in accordance with applicable regulations (Agustyawati et al. , 2. The higher the ROA, the greater the level of profit achieved by the The higher the profit that can be achieved by the company, the better the company's position in terms of asset utilisation (Lestari et al. , 2.

One indicator of dividend policy is the Dividend Payout Ratio (DPR). The DPR is the ratio between a company's profits and the amount of dividends distributed by the company to investors (Anindya & Muzakir, 2.

The regression model in this study examines the effect of sustainability report disclosure (SRDI) and financial performance (ROA) on firm value (PBV) with dividend policy (DPR) as a mediating variable.

CONCLUSION The test results show that sustainability reports do not have a significant effect on dividend policy, with a coefficient of 0. 153 and significance of 0. 653 (> 0. , so H1 is rejected. This indicates that investors prioritise financial performance over non-financial sustainability information. According to stakeholder theory, sustainability reports are a form of corporate responsibility to stakeholders and should increase trust and encourage dividend distribution. However, these results show that 4147 | P a g e https://dinastipub. org/DIJEFA Vol. No. 5, 2025 sustainability aspects are not yet a primary consideration in dividend policy. These findings are in line with the research of Tjandra & Yopie, . and Supriyadi et al, . The test results show that projected financial performance measured by ROA has a significant positive effect on dividend policy, with a coefficient of 0. 348 and significance of 0. 000 (< 0. The higher the ROA, the greater the company's ability to pay dividends, as high profits are the primary indicator of dividend payments. According to signalling theory, dividend payments reflect good performance and serve as a positive signal to investors. This finding supports the research of Meirawati et al. Prasetyoningrum et al. , and Zakaria . that financial performance has a positive effect on dividend policy. The test results show that sustainability reports have a significant negative effect on firm value, with a coefficient of -2. 286 and significance of 0. 000 (< 0. This indicates that the more sustainability disclosures there are, the more firm value may decrease due to improper management. According to stakeholder theory, poor-quality or merely symbolic disclosures can lead to negative perceptions and distrust among stakeholders. Excessive transparency without corresponding implementation can expose the company's weaknesses. These findings align with the research of Susianto & Wirakusuma, . , and Seth & Mahenthiran . The test results show that financial performance, proxied by ROA, has a significant positive effect on firm value, with a coefficient of 0. 422 and significance of 0. 000 (< 0. This indicates that financial performance is the primary factor investors consider when evaluating a company's prospects. According to signalling theory, good financial information sends a positive signal to investors about the efficiency and sustainability of a company's profits. High financial performance increases a company's attractiveness to investors. These findings are in line with the research of Febriana et al. Lestari, . , and Novianti et al. The test results show that the dividend policy proxied by the Dividend Payout Ratio (DPR) has a significant positive effect on firm value, with a coefficient of 0. 268 and significance of 0. 019 (< 0. This means that the higher the dividends distributed, the greater the firm value. According to signalling theory, dividends reflect financial stability and good prospects, as well as reducing information asymmetry between management and investors. Investors respond positively to companies that consistently pay dividends because they are considered to indicate healthy financial performance. This finding is consistent with the research of Fatmawati et al. Chasiotin et al. , and Seth & Mahenthiran . The Sobel test results indicate that dividend policy does not mediate the effect of sustainability reports on firm value (Z = 0. 4422 < 1. , thus rejecting H6. This suggests that sustainability aspects have not yet become a basis for dividend determination. Dividends do not function as a channel for sustainability communication, indicating that sustainability reports are still symbolic and not yet This finding supports the research of Danyswara & Hartono . The Sobel test results show that dividend policy partially mediates the effect of financial performance on firm value (Z = 2. 196 > 1. , so H7 is accepted. This means that ROA not only has a direct effect on company value, but also an indirect effect through dividend policy. In line with signalling theory, dividends serve as a tool for management to send positive signals to investors, reduce information asymmetry, and enhance market perception. These findings support the research of Idrus & Anwar . and Lestari . REFERENCES
