CSX Q3 2026 Earnings: Record $4.02B Revenue as Diesel Hits $4.24

CSX reported record quarterly revenue of $4.02 billion on October 21, 2026, up 12%, with diluted earnings per share of $0.57, up 54%. It did that while paying $4.24 a gallon for locomotive diesel, up 67% — and while running fewer trains on time than a year ago. Pricing power across every freight market, a fuel surcharge that doubled to $466 million, and the absence of last year's $164 million goodwill write-down carried the quarter, and the operating margin expanded 880 basis points to 39.1%.

The Headline Numbers​

CSX's fiscal year is the calendar year, so the third quarter of 2026 is the three months ended September 30, 2026. Every figure below comes from the Form 10-Q and the earnings release with its Quarterly Financial Report, all filed on October 21.

Revenue rose $430 million while operating expense fell $53 million, so operating income grew $483 million — more than the entire revenue gain. That is what a clean comparison does: last year's quarter carried a $164 million non-cash goodwill impairment on the Quality Carriers trucking subsidiary, and this year's carries none. Strip the impairment from the base and the growth is still emphatic — operating income +25%, net income +29%, EPS +30% — but the mechanism changes. It is not cost cutting. Fuel expense alone rose $170 million on 67% higher diesel prices; labor rose $19 million on incentive compensation and wage inflation. What covered it was price: fuel surcharge revenue nearly doubled to $466 million, and revenue per unit rose in every merchandise line, in intermodal (+13%), and in coal (+7%).

Below the line, interest expense was essentially flat at $207 million, other income held at $21 million, and the tax provision rose $128 million as the effective rate climbed to 24.0% from 22.7%. Average diluted shares fell 0.7% to 1,853 million on buybacks, adding a touch to the 54% EPS gain.

Revenue Deep Dive​

Total volume was 1.69 million units, up 5%, and the mix tells the pricing story — every market grew revenue faster than volume, which means rate, not just carloads.

Merchandise (61% of revenue) grew 11% on 3% more units. The release attributes the quarter to "higher volume and pricing across merchandise, intermodal, and coal" — the closest thing to a pricing-momentum signal in the filing, and the ledger backs it: revenue per unit rose 6–10% in all seven merchandise lines, including the three that shipped fewer units. Metals and equipment led at +19% on steel, equipment and aluminum shipments; chemicals added 7% volume on petcoke, waste, plastics and crude oil. Fertilizers shrank 13% in volume as higher input costs cut demand, yet still priced +7%.

Intermodal was the standout at +20% revenue on +7% volume. Domestic shipments grew on "wins with key customers, new service offerings and a tightening truck environment," while international slipped slightly. That tightening-truck line matters: when trucking capacity tightens, freight spills onto rails, and CSX names it twice — here and in forest products, where lumber benefited from "a tighter trucking environment." It is a demand tailwind the company did not create and cannot control.

Coal (+10% revenue, +2% volume) ran on exports: metallurgical and thermal shipments rose, helped by re-opened mines, while domestic utility coal fell 3% to 10.7 million tons. Export tonnage of 10.6 million tons now essentially equals domestic — the coal book is a met-coal export franchise with a shrinking utility appendage.

Trucking revenue rose 10% to $227 million "primarily due to higher fuel surcharge" — the surcharge passing through Quality Carriers' rates. With the subsidiary's goodwill fully written off last year, trucking is now a zero-goodwill business priced off diesel.

Two numbers tie the thesis together: fuel surcharge revenue of $466 million covered the $451 million fuel bill 1.03x, versus 0.83x a year ago — and the $232 million surcharge increase alone funded more than half the revenue gain. This is the company: a pricing and pass-through machine layered over 5% volume growth.

The Margin Story​

Railroads report no gross margin — the margin is the operating margin, and CSX's ran a remarkable arc:

Mechanically, the 880-basis-point expansion decomposes into three pieces. First, $164 million of last year's expense — 4.6 margin points — was the goodwill impairment, which did not repeat. Second, purchased services fell $73 million on efficiency savings and the absence of prior-year network-disruption and contract-restructuring costs. Third, and most durable, revenue per unit outran cost per unit: labor cost per unit actually fell as headcount dropped 1,226 rail employees (−6%) while volume grew 5%, and the fuel surcharge more than covered diesel.

The bear-reading check is the fuel lag: CSX estimates the two-month lag between highway diesel prices and its surcharge formula cost it $(36) million this quarter versus $(11) million last year. Diesel spiked faster than the surcharge could follow, so the true pricing gain is slightly larger than reported — but it also means a diesel decline would flatter future quarters the same way it punished this one.

The One Big Question: record revenue on a deteriorating railroad?​

Here is the tension the income statement hides: CSX moved 5% more freight, for record revenue, while running a worse railroad than a year ago.

Velocity fell, dwell rose 12%, and trip-plan performance dropped double digits in both carload and intermodal — while cars online grew 6% to 128,828. The network absorbed more cars, moved them slower, and delivered fewer on plan. CEO Steve Angel said "disciplined execution helped us move more freight, for more customers, while maintaining our high standards for safety and service" — and the safety half is verifiably true, with the personal injury index improving 17% and the train accident rate 5%. The service half is not yet in the numbers.

The bull case is that this is transient congestion from volume the railroad is still digesting: dwell and trip-plan performance lag headcount and crew positioning, and 6% fewer rail employees moving 5% more units is exactly the setup where service dips before productivity catches up. The bear case is that CSX is sweating the asset — record margins today funded by service quality that shows up in tomorrow's volume, as shippers with a choice (and intermodal shippers always have a trucking choice) defect. Angel's promise of "continued progress toward best-in-class performance in 2027" sets the test: velocity and trip-plan performance must inflect within two quarters, or the pricing power funding this margin starts to look extracted rather than earned.

The peer contrast sharpens it. Union Pacific, the western Class I, printed its own record quarter a day later:

Same diesel shock, same volume tailwind — and both fuel machines covered the spike itself about 1.4x over: CSX's $232 million surcharge gain against a $170 million fuel-cost gain matches UP's $598 million against $424 million. The difference is the starting point. UP entered the spike with its surcharge already covering fuel (0.98x) and exited at ~1.15x; CSX entered under-covered at 0.83x and clawed to 1.03x. UP's margin sits nearly two points higher on the same dynamic. CSX's quarter is the stronger growth story (record revenue, +52% net income off a depressed base); UP's is the stronger franchise story. CSX bulls should want the surcharge mechanism and the service metrics, in that order.

Tracking a $4B quarter in plain text​

A railroad income statement is deceptively simple — six expense lines — which is exactly why modeling it in Beancount clarifies it: double-entry forces every dollar of the $4.02 billion to reconcile, and the things management would rather you skim (last year's impairment, the reclassified gains line, the goodwill split) have to sit on labeled lines. We follow how we model every company.

Income posts negative (credit) and expenses positive (debit), so the transaction sums to zero with net income flowing to equity. Note what is absent: no goodwill impairment line this quarter, versus $164 million in Q3 2025 — the single line that explains nearly a third of the reported growth.

The balance-sheet number that tells the narrative is not the track — it is the debt wall. Current maturities of long-term debt jumped to $1,702 million from $708 million at year-end, a $1 billion wall now due within twelve months, while long-term debt fell $1,063 million. CSX rebuilt cash to $1,223 million and generated $2,648 million of nine-month free cash flow, so the wall is fundable — but 2027 is a refinancing year wearing a record quarter's clothes:

The Multi-Year Arc​

The ledger opens at FY2024 — the two audited annuals plus the current quarter, the standard bootstrap for a new company — with FY2023 comparatives from the 10-K for context:

The arc is a two-year squeeze followed by a snap-back. Revenue slid 4% across FY2024–FY2025 on export coal benchmark rates, soft merchandise volume and Hurricane Helene's Blue Ridge rebuild (~$470 million of 2025 property additions), while the trucking recession forced $272 million of cumulative Quality Carriers goodwill impairments and the operating margin sagged five points. Q3 2026 reverses all three at once: coal exports recovering on re-opened mines, pricing power restored in every market, and a zero-impairment comparison.

The compounding story underneath is capital return, not growth. CSX bought back $7.1 billion of stock across FY2023–FY2025 and raised its dividend for the 21st straight year, cutting diluted shares from 2,013 million to 1,873 million. Properties grew $2.1 billion over the same span — the railroad reinvests roughly $2.3–2.9 billion a year in track and equipment, then returns what is left. Nine-month 2026 free cash flow of $2,648 million, up 148%, says the machine is throwing off more cash than it has uses for at current capex.

The Verdict: Bull vs. Bear​

Bull Case

• Pricing power is real and broad: revenue per unit rose in all seven merchandise lines plus intermodal (+13%) and coal (+7%), including markets that shipped fewer units — rate, not mix.
• The impairment overhang is gone: Quality Carriers goodwill is fully written off, so the $272 million cumulative drag of FY2024–FY2025 cannot repeat; every future comparison is clean.
• Fuel is a pass-through, proven at $4.24: the surcharge covered the fuel bill 1.03x at 67%-higher diesel; any diesel retreat drops straight to margin.
• Cash generation inflected: nine-month free cash flow of $2,648 million (+148%) covers the $1.7 billion debt wall, the dividend ($0.14/share quarterly) and buybacks with room to spare.
• Volume is accelerating into 2027: 5% unit growth with intermodal +7% on customer wins and a tightening truck market — the mix (domestic intermodal, chemicals, metals) favors 2027 pricing.

Bear Case

• Service is deteriorating, not "maintained": carload trip-plan performance fell 12 points to 73% and on-time arrivals to 56% — shippers experiencing this quarter will remember it in next year's contract talks.
• The margin is flattered by comparison: 4.6 of the 8.8 margin points of expansion are last year's impairment not repeating; the clean run-rate gain is closer to 4 points.
• $1.7 billion of debt comes due within a year: current maturities more than doubled to $1,702 million, and refinancing in a higher-rate environment raises the $844 million annual interest run-rate.
• Diesel cuts both ways: the same surcharge mechanism that covered $4.24 diesel unwinds if prices fall — and the $(36) million fuel lag shows how fast spikes punish the gap quarters.
• Management guided to nothing: the release contains no volume, margin or capex outlook — "progress toward best-in-class performance in 2027" is a slogan, not a forecast, and no signal in the filing says demand exceeds supply.

Our Take: Buy the pricing, watch the railroad. The 39.1% margin is more real than it looks — rate gains across every market, headcount down 6% on 5% more volume, and a fuel mechanism that held at historic diesel prices — but a railroad that delivers 56% of trains on time is borrowing from its future. If velocity and trip-plan performance inflect by Q1 2027, this quarter marks CSX's emergence from its two-year squeeze as the better operator; if they do not, Union Pacific's merger-built western network will set the industry's service standard and CSX will compete on price it just spent. The service metrics, not the margin, are the number to watch next quarter.
