Sustainable business has become highly sought after today by stakeholders, which explains the importance of CSR for companies. Companies are required to work sustainably in order to legitimize themselves both in the market and society. This can be done by fulfilling and satisfying the economic, environmental and sustainable, as well as the social frameworks that exist in business society. Despite CSR's central role in companies, researchers have differentiated meanings on whether CSR initiatives really improve corporate profitability in terms of financial performance, and whether it has a positive relationship with corporate value. Regarding this, the report examines CSR's relationship to CFP and company value, through the profitability measures ROA and ROE, as well as the valuation measures market value and P/E ratio. A quantitative method has been applied to examine the companies published on Dagens Industri's sustainability index for the year 2021. Dagens Industri's list includes the largest listed companies in the GICS categories on the Swedish stock market exchange. The study uses regression analysis as a choice of statistical analysis method to examine the variables relationships. From the regressions, a small part of the result showed a weak negative relationship between CSR and ROA. The regressions otherwise mainly showed a non-significant relationship between CSR and a company's profitability and value. The variables do not have a significant relationship with each other, and a neutral relationship between them can thus be demonstrated. The existing research gap is therefore still ambiguous, hence the room for further future studies in the field.
