Gasoline and petroleum wholesaling

2013 revenue: $388.57 billion

2018 revenue: $439.53 billion

The gasoline and petroleum wholesaling industry's revenue faces risks from global crude oil prices. Geopolitics in the Middle East pose a risk, and a "legislative push for fuel efficiency, including higher miles per gallon required for cars and light trucks, will weaken domestic demand."

While the risk level for this industry is 'high,' their significance in the petroleum product supply chain should help revenue rise at an average annual rate of 2.5% over the next five years.
