Union Pacific, one of the largest U.S. freight railroads, collected $91.1 million more in fuel surcharges than it actually spent on fuel during the second quarter, according to filings with the Surface Transportation Board (STB). The gap, first reported by Reuters, is drawing criticism from shippers and regulators as the company seeks approval for its proposed $85 billion acquisition of rival Norfolk Southern.
How fuel surcharges work
Fuel surcharges are an extra fee that railroads add to shipping rates to help offset changes in diesel prices. When fuel costs rise, the surcharge is supposed to climb so the railroad doesn't eat the higher expense. When fuel prices fall, the surcharge should drop too. The idea is to keep shipping rates stable and predictable for customers while protecting the railroad's profit margins.
U.S. freight railroads are unusual in that they must report both their fuel spending and their fuel surcharge revenue to the STB, the federal agency that oversees rail mergers and rates. That transparency lets regulators, customers, and competitors see exactly how much the surcharge is bringing in versus what the railroad is paying at the pump.
In Union Pacific's case, the second-quarter numbers show a clear surplus: the company took in $91.1 million more than it spent on fuel. That means the surcharge was generating more revenue than the actual fuel bill, a situation that critics argue is a windfall rather than a cost-recovery mechanism.
Why the Norfolk Southern deal matters
Union Pacific's $85 billion bid for Norfolk Southern would create a coast-to-coast rail network, but it needs approval from the STB. The board evaluates proposed mergers on whether they serve the public interest, including their impact on competition, service, and rates.
Critics of the deal, including shipper groups and some lawmakers, are using the fuel surcharge data to argue that Union Pacific already has too much pricing power. If the railroad can collect more in surcharges than it spends on fuel, they say, that's evidence it can push rates higher without competitive pressure. A merger with Norfolk Southern, they argue, would only make that problem worse by eliminating a major competitor in many corridors.
Union Pacific has defended its surcharge practices, saying they are designed to recover fuel costs and are applied consistently across its network. The company has also argued that the merger would create efficiencies and improve service for customers.
What it means for investors
For everyday investors, the fuel surcharge gap is a reminder that railroad profits can be boosted by factors beyond just moving goods. Fuel surcharges are a significant revenue stream for railroads, and when diesel prices are volatile, the timing of surcharge adjustments can create short-term swings in earnings.
The bigger picture is the merger itself. If the STB approves the deal, Union Pacific would become an even larger player in the freight rail industry, potentially giving it more pricing power. That could be good for shareholders in the form of higher profits, but it also carries regulatory risk. The STB has been more skeptical of rail mergers in recent years, and the fuel surcharge controversy could give the board another reason to scrutinize the deal.
Investors should also note that the $91.1 million surplus is a relatively small slice of Union Pacific's overall revenue, which runs into the billions each quarter. But the symbolic weight is larger: it feeds a narrative that railroads are overcharging customers, which could lead to tighter regulation or political pressure.
What to watch next
The STB's review of the Norfolk Southern deal is expected to take months, and the fuel surcharge issue is likely to come up in hearings and public comments. Investors will also be watching Union Pacific's next quarterly filings to see if the surplus persists or narrows as fuel prices move.
For now, the key takeaway is that fuel surcharges are not just a pass-through cost. They can be a source of profit, and that's a detail worth understanding when evaluating railroad stocks or the broader shipping industry.
