After the close Zoe's Kitchen (ZOES) reported that Q1 results easily beat estimates on the backs of solid 8.1% comp sales growth. The comps slightly topped the 7.7% generated in Q4 last year. Remember, that most retailers struggled during Q1 so Zoe's Kitchen produced exceptional results. The exceptional numbers though is only producing a roughly 5% gain in after hours to around $39 as the company mostly maintains previous guidance. The comp sales guidance was modestly increased from 4.5% to 6.0%, up from previous guidance of 4.0% to 5.5%. The company tends to be conservative, but the numbers suggest deceleration during the year and the market hates those scenarios. With a market cap over $750 million, the stock probably struggles to gain much momentum trading at roughly 2.7x sales estimates of $280 million. The concept remains a stock to own, especially on any dips with only 174 company-owned restaurants open at the end of Q1. Disclosure: Long ZOES
