Hershey is a leading US confectionery manufacturer (around a $55 billion market, according to Euromonitor), controlling 35% of the domestic chocolate aisle. Beyond its namesake label, the firm's portfolio has expanded over the last 85 years and now comprises 100 brands, including Reese's, Kit Kat, Kisses, and Ice Breakers.

The firm has sought inorganic opportunities to extend its reach beyond its core confectionery business, adding Amplify Snack Brands and its Skinny Pop ready-to-eat popcorn to its portfolio, as well as Pirate Brands, Dot's Pretzels, and LesserEvil over the past few years.
