Lululemon Athletica Inc. shares LULU, -3.68% slid 7% in premarket trade Monday, after the maker of yoga gear said fourth-quarter sales and profit will come in at the low end of its guidance ranges, after the omicron variant of the coronavirus hurt staffing levels in certain locations. The company is now expecting per-share earnings to come in at the low end of a $3.24 to $3.31 range, and for adjusted per-share earnings to come in at the low end of its $3.25 to $3.32 range.
