  We study superconductivity in a Weyl semimetal with broken time-reversal
symmetry and stabilized by a point-group symmetry. The resulting
superconducting phase is characterized by topologically protected bulk nodes
and surface states with Fermi arcs. The topological invariant governing the
system is calculated using changes in eigenvalues of the point-group operator
along high-symmetry momentum lines. We show that this invariant is determined
by the Fermi surface topology of the Weyl semimetal. We discuss the effect of
surface orientation and $C_4$-breaking strain as possible experimental
consequences.
