Goldman Sachs analyst Katherine Fogertey left Wingstop's first-ever investor day positive on the company's long-term growth opportunity and goal to become a top 10 global restaurant brand. The analyst attributes the 4% share selloff yesterday to concerns that unit growth in the quarter was six shy of consensus estimates, and an announcement of accelerated investments to support International growth, in addition to a widening gap in company-owned vs franchised same-store-sales. Fogertey, however, is a buyer of Wingstop on the selloff. The unit "miss" was more a function of permit slippage and not a signal of a slowdown in the overall unit growth story, the analyst tells investors in a research note. Further, Wingstop's international investments should pay dividends longer term and the gap in same-store-sales is not very meaningful, says Fogertey. The analyst lowered her price target for Wingstop to $135 from $140 and keeps a Conviction Buy rating on the shares.
