3 External stakeholders Internal stakeholders Antin’s stakeholder engagement approach Antin has integrated sustainability principles into its relationships with actors across al l operations. Education, dialogue, awareness-raising, and collaboration on these issues are of key importance in building and maintaining strong stakeholder relationships, and these concepts go hand-in-hand with Antin's belief that sustainability is vital to good business practice and creates long-term value for investors. Stakeholder engagement occurs continuously, through both formalised reporting and ad hoc communication. 3 For employees, each permanent team member has a performance review with their manager twice a year. More informally, Antin regularly hosts offsites as well as ad hoc events such as company drinks or dinners.
