Lululemon is currently hunting for a new CEO after the abrupt departure of its last leader. Meanwhile, the executive team's long-term plan targets reaching $4 billion of annual revenue by 2020. Thanks to the strong first quarter, the retailer is now on track to cross $3 billion in the current fiscal year. If profit margins keep expanding, powered by a string of popular product launches, then Lululemon is likely to generate much-faster earnings growth during that period.
