Want to see what sits behind that valuation gap? According to yiannisz, the narrative refers to steady revenue expansion, firming profit margins and a premium future earnings multiple. You can compare those assumptions with your own expectations for SiteOne Landscape Supply.

Result: Fair Value of $131.30 (UNDERVALUED)
