Union Pacific Corporation (NYSE:UNP) reported $91.1 million more in fuel-surcharge revenue than in fuel cost during the second quarter, according to its Surface Transportation Board filing. Management separately attributed $0.14 of EPS, approximately $83.2 million using diluted weighted-average shares, to the net difference between fuel expense and surcharge revenue.
That represented about 4% of quarterly net income, but the comparison was striking. Norfolk Southern reported a $3.6 million surplus, and CSX reported $8.4 million. Union Pacific Corporation (NYSE:UNP) was also the only major U.S. railroad whose fuel surcharges exceeded fuel costs over the first half.
The contribution is too small to reshape the long-term financial case. The regulatory narrative may be different because Union Pacific Corporation (NYSE:UNP) is seeking approval for its proposed $85 billion acquisition of Norfolk Southern.
BULL CASE: THE SURPLUS REFLECTS CONTRACT MECHANICS
The surcharges use benchmark-linked formulas incorporated into published pricing programs or negotiated customer arrangements. They can lag fuel movements by two months.
That timing cut both ways. Union Pacific Corporation (NYSE:UNP) recovered $34.8 million less than its fuel expense during the first quarter. The first-half surplus was $56.4 million, while 2025 ended with surcharge revenue $48 million below fuel expense. A single quarter does not establish a permanent earnings source.
Union Pacific Corporation (NYSE:UNP) also produced operating gains. Second-quarter revenue rose 12% to $6.9 billion, while freight revenue excluding fuel surcharges increased 4%. Volume, core pricing and productivity contributed, and fuel consumption per thousand gross ton-miles improved 1%.
Higher fuel prices still hurt the operating ratio by 120 basis points even as the surcharge timing lifted EPS. For Union Pacific Corporation (NYSE:UNP), the $0.14 benefit looks more like a timing-related earnings-quality issue than evidence that fuel became a lasting profit center.
The railroads say a coast-to-coast network would reduce interchange delays, save shippers an estimated $3.5 billion annually, and shift an estimated 2.1 million annual truckloads from road to rail.
BEAR CASE: THE COMPARISON GIVES OPPONENTS A TALKING POINT
The problem for Union Pacific Corporation (NYSE:UNP) is not simply whether its formulas comply with existing rules. Benchmark-based fuel-surcharge programs remain permissible, although the STB has prohibited certain calculation practices. Its surplus still dwarfed those of eastern rivals during a politically sensitive merger review.
Opponents already argue that the combined railroad could raise shipping costs. BNSF has told regulators that the merged company would have the opportunity to apply Union Pacific’s high-price strategies nationally. The $91.1 million gap gives that argument a concrete figure.
The STB is examining enhanced competition, market-share projections, and downstream merger effects. The surcharge data will not decide the case, but it could make Union Pacific Corporation (NYSE:UNP) spend more time proving that its transcontinental network would benefit customers rather than strengthen its pricing power.
INSIDER MONKEY’S HEDGE FUND DATA ANALYSIS
The filings available so far reflect positions before the August fuel-surcharge report. According to Insider Monkey’s latest quarterly data, 96 hedge funds held Union Pacific at the end of the first quarter of 2026, down from 106 three months earlier.
COULD THE SURCHARGE SURPLUS HURT THE DEAL?
The $83.2 million EPS contribution is not material to the long-term earnings power of Union Pacific Corporation (NYSE:UNP). It is potentially more important as merger optics than as an earnings item.
The bull case is that benchmark-linked formulas temporarily over-recovered fuel costs after under-recovering them earlier. The bear case is that opponents could portray the size of the surplus as evidence of the pricing leverage they fear.
The disclosure is unlikely to stop the acquisition on its own. It could still raise the regulatory cost of proving that greater network efficiency, not more aggressive customer pricing, will define the combined railroad.
