Chipotle Mexican Grill — Q3 comparable sales +2.1% with positive transaction growth for a third straight quarter; revenue beat estimates, digital mix rose to 38.8%, and new-menu/chipotlane momentum offset margin pressure.
Huntington Ingalls — Record Q3 revenue $3.5B, EPS $5.48 (vs ~$4.36 consensus), $32.4B in new awards and backlog to $86.2B; raised shipbuilding revenue guidance with strong free cash flow.
