CSX (CSX) Q3 2026 earnings review
CSX profit climbs on cost cuts, but train delays persist
CSX, the eastern US freight railroad, grew profit rapidly by cutting overhead costs while moving more freight, even as train delays persisted. Third-quarter revenue rose 12% to $4.02 billion on 5% higher shipment volume, though by our math higher fuel surcharges supplied slightly more than half of the dollar sales gain. Chief executive Steve Angel kept total expenses down 2% despite a 67% jump in locomotive fuel prices, lifting the operating margin to 39.1%.
| Revenue excluding fuel surcharges | +5.9% from a year ago by our math (total revenue +12%) |
|---|---|
| Operating margin | 39.1% +4.2 percentage points vs Q3 2025 excluding one-offs |
| Profit per share | $0.57 +30% vs Q3 2025 excluding one-offs (+54% reported) |
| Nine-month free cash flow | $2,648M $1,066M a year ago |
⚖️ Verdict: 🟢 Bullish
The story got better because operational cost cuts in labor and outside services expanded margins without relying on last quarter's large real estate gains, and tighter trucking pushed container volume up 7%. One caution: customer delivery schedules missed management's goal of a broad third-quarter rebound, as container on-time performance fell to 83% and railcar yard waits stayed 12% longer than a year ago.
The question now is whether running 5% more freight with 6% fewer employees is straining the rail network or simply reflecting temporary summer congestion. If the network is short on crews, CSX will have to hire workers and give back part of its cost savings; if the delays are temporary, train speeds and on-time arrivals will recover without extra spending. Fourth-quarter trip plan compliance and labor expenses will settle it.
🐂 Bull Case
Cost Cuts Expanded the Operating Margin
CSX runs a freight railroad across the eastern United States, and chief executive Steve Angel is cutting overhead to lift profit margins. Operating margin reached 39.1%, up 8.8 percentage points from a year ago, or 4.2 percentage points by our math when excluding last year's $164 million accounting write-down at its trucking unit.
The company drove that improvement by reducing outside contractor spending and operating with 1,320 fewer employees than a year ago. Purchased services and other expenses — outside contractors, repairs and overhead — dropped 4.0 percentage points of revenue by our math, driven by $42 million in "cost reductions across operating and support functions". Labor and fringe benefits fell 2.0 percentage points of revenue by our math because lower headcount saved $50 million, which offset $53 million in higher bonus accruals and $38 million in wage inflation.
This matters because the savings came from everyday operations rather than one-off asset sales. Real estate gains contributed only $11 million this quarter against $44 million in the first quarter, and equipment depreciation savings narrowed to $11 million.
What to watch: fourth-quarter operating margin against the 33.0% level implied by the prior full-year floor. Holding above 36% during slower winter shipping would show that the lower headcount can sustain margins through union wage increases.
Tighter Trucking Lifted Rail Volumes and Export Coal
CSX needs freight moving off highways and onto its tracks to grow volume. Total shipments rose 5% from a year ago to 1.69 million units, as intermodal — shipping containers that move between trains and trucks — grew 7% to 820,000 units on "wins with key customers, new service offerings and a tightening truck environment".
- Intermodal revenue: $634 million, up 20% from a year ago on 7% higher volume
- Metals and equipment volume: up 12%, lifting segment revenue 19% to $267 million
- Forest products volume: up 6% on "benefits from a tighter trucking environment"
- Export coal volume: up 7% to 10.6 million tons following mine reopenings
The volume gains matter because freight rates also held up. Even though lower-priced container shipments grew faster than industrial carloads, average revenue per unit excluding fuel surcharges rose 1.2% from a year ago by our math, reversing a 1% drop last quarter.
What to watch: domestic intermodal volume in the fourth quarter and the 2027 shipping contract renewals. Continued volume growth above 5% would prove that new double-stack routes are winning permanent freight from highway trucks.
🐻 Bear Case
Fuel Surcharges Drove Half the Revenue Gain
CSX charges customers a fuel fee tied to highway diesel prices, which inflates revenue when energy prices climb. Total revenue jumped 12% from a year ago to $4.02 billion, adding $430 million, because locomotive fuel prices jumped 67% to $4.24 per gallon.
The company collected $466 million in fuel surcharges, up $232 million from a year ago. By our math, fuel surcharges supplied 54% of the quarter's total dollar revenue growth, while revenue excluding fuel surcharges grew 5.9%. Fuel expense also climbed $170 million to $451 million, adding 3.4 percentage points of revenue to operating costs by our math, even with a $36 million timing lag on surcharge collections.
This matters because fuel surcharges pass through diesel swings rather than reflecting underlying shipping demand. If diesel prices retreat toward last year's $2.54 per gallon, reported revenue growth will drop by half even if freight volumes hold steady.
What to watch: fourth-quarter fuel surcharge revenue against last year's $243 million base. A smaller surcharge gain will test whether underlying freight volume and pricing can carry top-line growth above 5% on their own.
Train Delays Worsened After Headcount Cuts
"CSX delivered strong earnings growth in the third quarter as disciplined execution helped us move more freight, for more customers, while maintaining our high standards for safety and service," chief executive Steve Angel said. Last quarter, executives promised that train schedules and yard delays would improve from the second quarter into the third.
Safety rates did improve, as personal injuries per 200,000 work hours fell 17% from a year ago, but customer service metrics remained well below last year's levels. Average train speed slipped 2% from a year ago to 18.6 miles per hour, and yard dwell — the time a railcar sits waiting in a terminal — worsened 12% to 10.6 hours. On-time carload deliveries dropped to 73% from 83% a year ago, and intermodal on-time performance fell to 83% from 93%.
This matters because the eastern railroad is handling 75,000 more freight units and 6% more active railcars on its tracks with 1,226 fewer rail workers. Slower cycle times already pushed equipment rent costs up 7%, and persistent delivery delays make it harder to raise prices when customer contracts renew.
What to watch: carload trip plan compliance in the fourth quarter. A recovery above 80% without a jump in labor costs would show the network can handle higher volume at current staffing levels.
Auto Outages and Utility Closures Slowed Select Freight
While chemical and metal shipments grew, three industrial markets lost volume this quarter. CSX warned last quarter that auto plant shutdowns and power plant closures would weigh on second-half carloads.
Those headwinds showed up in the third-quarter volume tables. Automotive shipments fell 2% from a year ago to 97,000 units because of a temporary re-tooling outage at a customer assembly plant. Fertilizer volume dropped 13% to 42,000 units as higher input costs curbed buyer demand, reducing fertilizer revenue by 6%. Domestic coal shipments also fell 3% to 10.7 million tons on lower utility plant deliveries.
What to watch: chemical and automotive carloads in the fourth quarter. A drop in chemical shipments would confirm that customers pulled orders forward into the first nine months of the year.
Risks this quarter didn't answer
Four standing items from prior quarters received no new figures in the third-quarter financial report.
- Industry consolidation costs: the expense breakdown did not state whether CSX continued paying merger advisory fees, which the conference call or quarterly filing may clarify.
- Core pricing gains: the report cited higher pricing across freight segments but gave no renewal price percentage or ex-fuel intermodal rate.
- Industrial development pipeline: the release gave no update on the roughly 100 customer facility projects scheduled to enter service this year.
- 2027 margin comparisons: Angel looked forward to "making continued progress toward best-in-class performance in 2027", but the release included no 2027 targets to measure how CSX will lap this year's cost cuts.
👓 Other Themes
Share Buybacks Nearly Doubled From Last Quarter
After slowing share repurchases in the first half of the year, CSX stepped up its buying in the third quarter. The railroad spent $543 million to buy back 11 million shares at an average price of $48.75, nearly double the $284 million spent on 6 million shares in the second quarter, bringing nine-month repurchases to $1.05 billion.
💲 Other KPIs
Free cash flow — operating cash after capital spending and property sales, before dividends — rose 66% from a year ago in the third quarter by our math, bringing the nine-month total to $2.65 billion. Nine-month capital spending fell to $1.71 billion from $2.23 billion as last year's $440 million Hurricane Helene track rebuild did not repeat.
Total debt minus cash and short-term investments fell by $999 million over the first nine months of the year by our math. The railroad held gross debt nearly unchanged at $18.80 billion while building its cash and short-term investments balance to $1.61 billion from $675 million at year-end.
Average diluted shares fell 0.8% from 1,867 million a year ago and dropped by 6 million shares from the second quarter. The lower share count added about 1 percentage point to per-share profit growth in the quarter.
❓ Key Questions
Did CSX raise its 2026 outlook after Q3?
The earnings release did not include a full-year outlook table. With nine-month revenue up 8% and free cash flow already at $2.65 billion, the prior full-year targets of 5–9% revenue growth and 80% cash flow growth imply a sharp fourth-quarter slowdown unless raised on the call.
Why did intermodal on-time arrivals fall to 83%?
Management expected service metrics to improve in the third quarter, and carload trip compliance ticked up 2 points from Q2 to 73%, but intermodal compliance dropped 5 points to 83% while yard dwell remained 12% worse than a year ago.
How much did renewal prices rise excluding fuel?
Average revenue per unit excluding fuel surcharges turned positive at +1.2% by our math despite higher intermodal mix, but management did not disclose the underlying contract price increase.
Did merger advisory spending continue in the third quarter?
Second-quarter outside service expenses included advisory fees for potential industry consolidation, and the third-quarter release did not state whether those costs continued or stopped.
