The struggles at B-Dubs continues. Buffalo Wild Wings (BWLD) posted earnings of $0.87 a share on revenue of $494.2 million on Tuesday. Analysts were looking for $1.27 a share on sales of $514.3 million. Shares fell about 5% to $142.50 in after-hours trading.

The stunning earnings whiff and pressured same-store sales will likely strengthen the hand of activist firm Marcato Capital. Recently, Marcato -- which has a 5.2% stake in Buffalo Wings -- nominated four members to the wing chain's board, citing a lack of management execution and board experience.
