@TheMuffinMan28 SRS is a PE rollout, bit of a hodgepodge of assets. Concentration in landscaping, pool and roofing. No exclusive relationships (GMS is for $AWI, regional duopoly across most categories). End customers are small homebuilders (more competitive, less scale benefit for distributors).

$DKNG Basically just said at the Craig Hallum Conference they are going to miss Q4 guidance. CEO: "literally had the worst stretch of the year, the last few weeks...sometimes that happens where you issue your guidance...So we'll see."
