We derive from first principles the mechanical pressure $P$, defined as theforce per unit area on a bounding wall, in a system of spherical, overdamped,active Brownian particles at density $\rho$. Our exact result relates $P$, inclosed form, to bulk correlators and shows that (i) $P(\rho)$ is a statefunction, independent of the particle-wall interaction; (ii) interactionscontribute two terms to $P$, one encoding the slow-down that drivesmotility-induced phase separation, and the other a direct contribution wellknown for passive systems; (iii) $P(\rho)$ is equal in coexisting phases. Wediscuss the consequences of these results for the motility-induced phaseseparation of active Brownian particles, and show that the densities atcoexistence do not satisfy a Maxwell construction on $P$.
