Marathon Partners' manager Mario Cibelli explains why e.l.f.’s ‘fast beauty’ strategy can get its cosmetics into market faster than “legacy” rivals. While he foresees a bright future for the company, he has real concerns about executive compensation. Cibelli, 50, who succeeded in installing two dissidents onto the board of Shutterfly in 2015, also suggested that e.l.f. needs to bring on a designated lead independent director that isn’t affiliated with buyout shop TPG.
