A surgical stapling apparatus includes a cartridge assembly, a firing assembly, and a lockout assembly. The cartridge assembly is configured to house a plurality of sets of surgical fasteners. The firing assembly is configured for repeated actuation wherein, upon each actuation, the firing assembly is moved from a first position to a second position to at least partially eject a set of surgical fasteners. The firing assembly further configured to translate from the second position back to the first position to reset the firing assembly for subsequent actuation. The lockout assembly is configured to permit a predetermined number of actuations and is configured to transition from a first condition, wherein subsequent actuation is permitted, to a second condition, wherein subsequent actuation is inhibited, when a number of previous actuations of the firing assembly is equal to the predetermined number of actuations.
