Deutsche Bank analyst Mike Baker sees "several reasons" for upside to the consensus comp forecast into AutoZone's Q4 results on September 18. The analyst is modeling comps to be up 3.1% compared to consensus of 2.4%. He sees favorable industry trends, some early signs that inflation should help comps, and help from cycling Hurricane Harvey at the end of the quarter. This, along with favorable gross margin trends, "well telegraphed" expense increases and a "below average" valuation leaves Baker positive on AutoZone shares into the print. He keeps a Buy rating on the name with an $805 price target.
