Examining the Causality between Integrated Reporting and Stock Market Capitalization. The Case of the European Renewable Energy Equipment and Services Industry

The International Accounting Standards Board (IASB) and the International Sustainability Standards Board (ISSB) of the IFRS Foundation support the integrated reporting of companies’ financial and sustainability performance to stakeholders. This paper aims to investigate whether financial and environmental, social, and corporate governance (ESG) practices have a real impact on the success of the companies in the European renewable energy equipment and services industry. Using the Granger test, the causality between the market capitalization and financial indicators was established, whereas no causality was identified between the market capitalization and ESG performance. The research led to the conclusion that the investment decision is mainly based on the information provided by the financial statements of the companies, the early stages of sustainability reporting regulation, and the need for increasing the quality and availability of corporate social responsibility information for investors.
