Stifel analyst Chris O'Cull said "it is no secret" that Luckin Coffee has made meaningful inroads in China's coffee market, noting that it has been widely reported that Luckin is projected to have 4,500 units by the end of this year, which is more than Starbucks' expected 4,200 units. He estimates Luckin's menu prices are generally 20%-30% below Starbucks, which has led many investors and some competitors to question the sustainability of these lower prices. However, O'Cull said his analysis suggests Luckin's retail model operates with lower costs and he contends its low-cost retail model is sustainable. Luckin may be positioned to gain disproportionate share in China, making it more challenging for Starbucks to grow sales there, concludes O'Cull, who keeps a Hold rating on Starbucks with a $65 price target.
