An exemplary turbomachine exhaust flow diverting assembly includes an outer flow diverter distributed about a rotational axis of a turbomachine. The outer flow diverter moveable between a first position and a second position. The outer flow diverter in the first position permits more flow through a main bypass flow passage and less flow through a third stream bypass flow passage. The outer flow diverter in the second position permits more flow through the third stream bypass flow passage and less flow through the main bypass flow passage.
