2024 FleetOwner 500: Private, the largest corporate fleets in the U.S.

More companies continue to invest in their transportation systems, growing their private fleets. The annual FleetOwner 500: Top Private Fleets list allows businesses to benchmark their transportation operations against their corporate peers.

Twenty-four new companies debut on the 2024 FleetOwner 500: Private list, our annual compilation of the most extensive commercial transportation operations run by companies to support their primary businesses. Those main businesses include wholesale and retail, food products, public utility, manufacturing, construction, sanitation, petroleum and gases, agriculture, non-trucking transportation, and more.

While there wasn’t much movement atop the list, infrastructure construction giant MasTec (whose subsidiaries include Energy Erectors, Sefnco Communications, Henkles & McCoy, and others) moved up five spots to No. 10—the only new Top 10 private fleet.

With nearly 28,000 commercial vehicles, national utility provider AT&T ranks No. 1 on the FO500: Private for the second straight year. Those vehicle numbers do not include the thousands of light-duty vehicles AT&T uses across the U.S.

PepsiCo, which includes subsidiary fleets such as Frito-Lay, ranks No. 2 for the third consecutive year. A classic mixed fleet, PepsiCo is the only company that ranks in the Top 10 of both most tractors (No. 2) and most straight trucks (No. 5). Later this month, we’ll have a feature on mixed fleet challenges, where Mari Roberts, Frito-Lay North America VP of transportation, shares some insights into how the company trains drivers and operates its mixed fleet.

These rankings are based on power units reported to the Federal Motor Carrier Safety Administration’s Safety and Fitness Electronic Records (SAFER) System. The FO500: Private only includes vehicle classes required to register with the U.S. Department of Transportation, leaving out some lighter-class fleets and units.

We also have more than a dozen Top 10 lists that break down private fleets by their company’s main business types and also by tractor, truck, and trailer population. No. 7 overall fleet Walmart ranks No. 1 on the tractor and trailer Top 10 lists. These Top 10 lists will be published on FleetOwner.com throughout the spring.

Other Top 10 lists focus on various business sectors and our Future 500 shows fleets that are just outside the 500 largest private carriers in the U.S.

Methodology

This is the second FleetOwner 500: Private list since revising how we gather the data that makes up our lists (the FO500: For-Hire version was published in February). In 2023, we partnered with the brilliant analysts at ProsperFleet, which rebuilt the FO500 from scratch and led to more than 120 new companies joining the list a year ago. So, this is the first year we can compare our revised methodology.

ProsperFleet primarily relies on the most recent information companies filed on form MCS-150 with the Federal Motor Carrier Safety Administration to count power units, trailers, and drivers. This ensures a consistent “basis” (a level playing field) to compile information. Analysts at ProsperFleet also use the companies’ websites, press releases, and hierarchy from their business databases to roll up USDOT operating entities to a single parent company. ProsperFleet then cleanses, validates, standardizes, and enhances company and contact information to create a complete fleet view.

For companies with subsidiaries and divisions that possess USDOT numbers, the vehicle counts of the subsidiaries are incorporated into the parent company’s total. Due to this consolidation, fleets that were previously on the list but were acquired in late 2022 or 2023 do not appear on the 2024 list. Instead, their power unit counts are reflected in the totals of their respective parent companies.

Below is an interactive display of the 2024 FleetOwner 500: Private list. You can re-sort the list by each column. This year, we’ve included a column denoting how each fleet’s 2024 ranking compares with the 2023 ranking. Read more about some of the changes that we instituted when the FO500: For-Hire list debuted earlier this year in Lane Shift Ahead.
