It is known that any 2-connected equimatchable graph is either bipartite, or factor-critical, and that these two classes are disjoint. This paper provides a description of k-connected equimatchable factor-critical graphs with respect to their k-cuts for $k\\ge 3$. As our main result we prove that if G is a k-connected equimatchable factor-critical graph with at least 2k+3 vertices and a k-cut S, then G-S has exactly two components and both these components are close to being complete or complete bipartite.
