Ann-Marie Campbell

Since being promoted to run all of Home Depot’s U.S. stores in 2016, Campbell has hit nearly $100 billion in sales. She’s giving stores a refresh, which has helped grow transactions as well as the amount customers spend. The future is more uncertain: In August, the 40-year-old DIY retailer lowered its sales forecast for the year, citing concerns about lumber prices and the impact of tariffs on consumers.
