Shake Shack (NYSE: SHAK) shares were trading around 10% lower after-hours on worse-than-expected guidance, while Q4 results came better than the Street estimates. Q4 EPS was ($0.11), better than the consensus estimate of ($0.18). Revenue grew 29% to $203.3 million, slightly above the consensus estimate of $202.54 million.

According to Randy Garutti, the CEO of Shake Shack, the company achieved a strong sales comeback in Q4, with record full 2021-year system-wide sales results ($1.1 billion) and same-Shack sales up 2.2% versus Q4/19 (and up 20.8% vs. Q4/20). However, the company’s sales were impacted by the sharp increase in Omicron cases in fiscal January, causing a decline in traffic, lost hours and Shack closures.

The company expects Q1/22 revenue to range from $196 million to $201.4 million, missing the consensus estimate of $210.87 million.
