Through this study, the authors aimed to make a synthesis of scientific works on the interdependence between financial performance and sustainable practices of companies. By applying the methods of synthesis, comparison, deduction, the authors concluded that there is no unanimity of opinion regarding the direct link between financial and sustainable performance. This fact is demonstrated by the synthesis of researches already carried out by other researchers, which are contradictory. At the same time, the authors conclude that an important factor which can influence financial performance is the disclosure of information on sustainable practices or sustainability principles underlying the company's business model. Accordingly, the authors recommend the implementation of an integrated reporting system, which, in addition to financial information, also contains non-financial information, including sustainable performance indicators.
