Crew oversaw $8.6 billion of Reynolds American’s net sales of $10.7 billion last year—a number that’s expected to surge in 2016. That’s when the company will report a full year of post-merger numbers after the conclusion of its June 2015 deal with Lorillard. Crew also added another title, COO, to her already impressive résumé in October, gaining oversight of manufacturing and R&D. And with CEO Susan Cameron rumored to be stepping down later this year, many industry watchers say Crew is the clear heir apparent at Reynolds.
