BofA/Merrill analyst Curtis Nagle said Select Comfort reported a strong Q1 beat but he continues to see earnings risk for the year. The analyst sees execution risk to the new 360 bed line rollout in mid Q2 given a past track record of inconsistent performance, pricing is likely to be flat which will limit ticket growth, and said the company has a greater reliance on driving comp traffic, which has been volatile. Curtis said Select Comfort has limited broad market appeal due to its highly niche product and reiterated his Underperform rating, but raised his price target to $21.50 from $18 on shares.
