We show that, up to strong cocycle conjugacy, every countable exact group admits a unique equivariantly O_2-absorbing, pointwise outer action on the Cuntz algebra O_2with the quasi-central approximation property (QAP). In particular, we establish the equivariant analogue of the Kirchberg O_2-absorption theorem for these groups. Based on my preprint arxiv:2004.09461.
