At what point does a business need a different operating model? FedEx Freight CEO John Smith believes his company has reached that point.

The newly independent company, which spun off from FedEx earlier this month, generates roughly $9 billion in annual revenue and operates one of the largest less-than-truckload networks in North America. Until recently, however, it sat inside a parent company approaching $90 billion in annual revenue.

That difference in scale shaped everything from capital allocation to technology investments, Smith told me during a recent interview.

“Rightfully so, the majority of that will go into the mothership,” he said, referring to how investment decisions naturally flowed toward FedEx’s much larger parcel business.

One theme surfaced repeatedly throughout our conversation: control. Control over capital allocation, technology investments, the sales organization, and the company’s approach to growth opportunities in healthcare, food and beverage, and small-business customers.
