BNSF Q3 Earnings Jump 19.3% to $1.73B as Volumes and Yields Climb

BNSF posted third-quarter net earnings of $1.73 billion, up 19.3% from $1.45 billion a year earlier, as higher freight volumes and operating efficiencies more than absorbed rising fuel costs. Parent Berkshire Hathaway (NYSE: BRK-B) reported the figure for the period ended Sept. 30.

The top line moved just as sharply. Railroad operating revenue climbed 14.7% to $6.87 billion, while car and unit volumes rose 3.9%. That gap — revenue growing nearly four times faster than shipments — tells the real story: pricing and fuel surcharges, not just traffic, drove the gain.

For shippers and forwarders, that spread matters. When a Class I railroad lifts revenue per unit faster than volume, it usually signals tight capacity, stronger yields on renewed contracts, or heavier fuel surcharge recovery. Any of the three raises the cost baseline for intermodal and carload customers heading into 2026 bids.

What did the operating ledger show?

Railroad operating earnings rose to $2.48 billion from $2.15 billion in the year-earlier quarter. Operating expenses climbed to $4.39 billion from $3.84 billion, but the expense increase stayed below the dollar gain in revenue — the efficiency story Berkshire highlighted.

Below the operating line, interest expense actually fell, to $273 million from $279 million. After interest and other net items, pretax earnings reached $2.27 billion against $1.91 billion a year ago.

Taxes worked in BNSF's favor too. The effective income tax rate declined to 23.7% from 24.2%, though income tax expense still rose to $537 million from $463 million because pretax profit grew.

How did coal perform?

Coal shipments fell 8.4% in the quarter, yet coal operating revenue edged up to roughly $800 million. Berkshire credited higher average revenue per car or unit — a mix of increased fuel surcharge revenue and improved yield — for more than offsetting the volume decline.

The nine-month pattern matched. Coal volumes dropped 6.3% through September, while coal operating revenue still crept higher to about $2.3 billion.

Is the full year tracking the same way?

Yes. Through September, BNSF's net earnings reached $4.66 billion, up 13% from $4.13 billion in the first nine months of 2025. Berkshire again attributed the improvement to higher freight volumes and operating efficiencies, partly offset by rising fuel expenses.

Nine-month railroad operating revenue rose 11.5% to $19.39 billion, against just 4.2% growth in car and unit volumes — the same revenue-outpacing-volume dynamic as the quarter. Railroad operating earnings for the period hit $6.80 billion, up from $5.98 billion.

Why does this matter for Berkshire?

Timing, mostly. Berkshire's total operating earnings declined to $12.71 billion from $13.49 billion a year earlier, yet BNSF's contribution grew from $1.45 billion to $1.73 billion. The railroad delivered a larger share of the conglomerate's earnings precisely when other units weakened, underscoring the franchise value Warren Buffett's railroad holds within the portfolio.

For the rail market, BNSF's quarter lands as evidence that Western rail demand and pricing power remain firm despite fuel cost headwinds. Expect yield discipline and fuel surcharge mechanics to stay central to BNSF's revenue trajectory as volume growth moderates through year-end.
