4.4.5 Exemplifying corporate citizenship

Description Antin aims to exemplify corporate citizenship by supporting the communities in which it operates and promoting responsible investment (RI) practices in the financial industry. Risks and opportunities Community engagement and support have been part of Antin’s DNA as a responsible company since its inception. These values are even more relevant given Antin’s new status as a publicly traded company on the Euronext Paris stock exchange. Poor corporate citizenship could affect Antin’s reputation, its viability as both a Fund Manager and investor, its ability to fundraise and meet investor and Shareholder expectations, and its ability to attract and retain key talent.
