This study examines the relationships between corporate sustainability (CS) performance of the companies (proxied by inclusion in sustainability index) listed in Borsa Istanbul (BIST, Istanbul, Turkey) and market-specific company performance measures over the period of 2014–2017. The results show that there is no strong evidence of the effect of inclusion in or exclusion from the BIST Sustainability Index (BIST SI) on stock returns and systematic risk (betas) of companies. However, the results reveal that inclusion in the BIST SI reduces the total risk of the companies and protects them from stock declines in case of a severe crisis by improving their resilience compared to other companies not included in the BIST SI. Although no significant link is found concerning the impact of the companies’ inclusion on the level of foreign ownership, a positive association is noted between BIST SI inclusion and the level of institutional ownership.

The discourse of corporate sustainability performance (CSP) has created an increasing motivation for companies to improve their competitive advantage. This study examines the drivers leading to a high level of CSP within non-financial Turkish companies listed in the Borsa Istanbul Sustainability Index. Drawing on both stakeholder and agency theories, we formulate a set of hypotheses that link CSP with ownership structure, board diversity, and firm-specific characteristics. Based on logit and probit models, the empirical results tend to confirm the positive influence of foreign and institutional ownerships in shaping CSP and indicate that CSP is positively linked with board size and the proportion of independent board members. Further, the findings show that companies with a leading level of CSP have a lower return than companies with mediocre CSP based on a market-based measure, Tobin’s Q.
