Caterpillar (CAT) Q3 2026 earnings review
Data centers lift Caterpillar profit, but tariffs squeeze mining
Caterpillar, the world's largest maker of construction and mining equipment, is selling engines for data centers faster than its factories can build them. Third-quarter revenue rose 17% from a year ago to $20.7 billion, while profit per share excluding one-offs climbed 45% to $7.20 on higher volumes and prices. Chief executive Joe Creed pointed to "strong order rates and a record backlog", and customer deposits on the balance sheet jumped 57%.
| Revenue | $20.7B +17.3% from a year ago |
|---|---|
| Operating margin, excluding one-offs | 20.6% 20.0% excluding tariff refunds, vs 17.5% a year ago |
| Power Generation retail sales to users | +75% from a year ago, up from +72% last quarter |
| Full-year tax rate outlook | Unchanged 23.0% excluding one-offs; revenue outlook not in release |
⚖️ Verdict: 🟢 Bullish
The story got better because end-user buying accelerated in power generation and held up in North American construction, while operating margin reached 20% by our math even without $128 million of tariff refunds. One caution: the mining division grew mainly because dealers stocked up while its profit margin slipped on tariff costs, and the prior full-year plan points to growth slowing to about 7% in the fourth quarter by our math.
The question now is whether factory capacity and end-user demand can overcome a planned fourth-quarter drop in dealer inventories and tougher comparisons from last year. If new engine capacity ships on time, Caterpillar will beat the 7% fourth-quarter growth rate implied by its prior plan; if bottlenecks hold and dealers cut orders, revenue growth will drop sharply. The fourth-quarter results and the quarterly filing's backlog figure will tell.
🐂 Bull Case
Data-Center Demand Pushes Power Generation Sales Up
Caterpillar's Power & Energy division makes large diesel and natural gas engines and industrial gas turbines. Sales in its Power Generation unit rose 30% from a year ago to $3.42 billion, "mainly in turbines and turbine-related services and in large reciprocating engines, primarily in data center applications", the company said. Retail sales of power generation equipment by dealers to end users grew 75%.
That 75% retail jump improved on a 72% gain in the second quarter and 48% in the first. Because end-user buying is growing more than twice as fast as factory shipments, unfulfilled orders keep flowing into the company's order backlog. The shift toward higher-margin power equipment also lifted the division's profit margin by 2.5 percentage points to 24.4%.
What to watch: first shipments of the restarted 10-megawatt gas engine line in the fourth quarter. On-time deliveries would show that new factory capacity is starting to narrow the gap between customer buying and Caterpillar's shipments.
Volume and Prices Lift Operating Margin
Caterpillar's operating margin, excluding one-offs, rose 3.1 percentage points from a year ago to 20.6%. That figure includes $128 million of tariff refunds under the International Emergency Economic Power Act (IEEPA), a US trade law. By our math, removing those refunds leaves a clean operating margin of 20.0%, still up 2.5 percentage points from last year's 17.5%.
- Cost of goods sold (cost of making products): 64.5% of revenue, down 1.7 percentage points by our math
- Selling, general and administrative expenses (overhead): 8.7% of revenue, down 1.6 percentage points by our math
- Price realization (net price increases): $663 million benefit across the machinery and power divisions
Higher equipment volume of $2.21 billion and price increases outweighed higher freight and material costs. Because clean margins sits well above the bottom of the company's long-term target range, the core business is absorbing ongoing tariff and factory expansion expenses.
What to watch: fourth-quarter operating margin excluding tariff refunds and pension adjustments. Holding near 20% during a seasonal fourth-quarter drop in dealer inventories would show that pricing power is covering tariff costs.
End-User Buying Carries North American Construction
Construction Industries sells excavators, loaders and pavers for building and infrastructure work. Revenue rose 18% from a year ago to $7.98 billion, and segment profit grew 33% to $1.83 billion. Volume added $874 million and higher prices added $349 million, which overcame $252 million of higher manufacturing and freight costs.
In the first half of the year, dealer restocking drove a large part of the division's growth. This quarter, Caterpillar said the volume gain was "primarily driven by higher sales of equipment to end users", with dealer retail sales up 27% in North America and 20% worldwide. End-user buying means machines are going onto job sites rather than sitting on dealer lots.
What to watch: the fourth-quarter change in Construction Industries dealer inventory in the full-year report. A reduction of more than $1 billion, as previously planned, would confirm that dealers are clearing stock into healthy customer demand.
🐻 Bear Case
Restocking and Tariffs Hold Back Mining Margins
"Our third-quarter results reflect the durability of our end markets, with strong order rates and a record backlog," chief executive Joe Creed said. Resource Industries, which sells mining trucks and locomotives, tells a weaker story. Revenue rose 15% from a year ago to $4.62 billion, but segment profit margin slipped 0.1 percentage points to 13.5%.
Unlike in construction, mining sales grew "primarily due to the impact from changes in dealer inventories", the company said. Combined retail sales to end users in the division rose only 4%, as mining and heavy construction retail sales grew 8% while rail retail sales fell 70%. Meanwhile, $208 million of unfavorable manufacturing costs "primarily reflected higher material costs, including tariffs", erasing most of the $277 million profit gain from volume and pricing.
What to watch: Resource Industries retail sales to users and segment profit margin next quarter. If dealer restocking pauses while retail sales stay near 4%, factory shipments and margins in the mining division will fall.
Factory Bottlenecks Cap Power Shipments
Caterpillar uses a shared manufacturing base to build large engines for data centers, oilfields and industrial machines. While Power Generation retail sales to users rose 75% from a year ago, retail sales in Oil and Gas grew only 5%, down from 36% in the fourth quarter of 2025, and Industrial retail sales fell 3%.
Even with slower demand in those two units freeing up factory space, total Power & Energy revenue rose 18% to $8.78 billion, half the 36% pace of the division's total retail sales. Factory capacity is still gating how fast the company can turn its order book into revenue, and the main expansion for large engines does not arrive until 2027.
What to watch: Power & Energy external revenue growth in the fourth quarter. A pickup above 18% would show that recent factory conversions in Kansas are lifting output before the 2027 engine plants open.
Risks this quarter didn't answer
The earnings release omitted full-year outlook numbers and several figures needed to test standing risks, which normally wait for the conference call or the quarterly filing.
- Order backlog size and duration: Creed noted "a record backlog", so it topped last quarter's $72.1 billion, but the exact figure, the share due beyond 12 months, and data-center customer concentration require the quarterly filing.
- Second-half dealer inventory reversal: the release gave no dollar figure for third-quarter dealer inventory changes or the planned fourth-quarter reduction.
- Gross tariff expense: the release reported $128 million of tariff refunds, down from $392 million last quarter, but did not state the gross tariff cost against the prior $600 million plan.
- Long-term order pricing: no update on how well inflation escalators on multi-year engine orders cover rising material costs.
💲 Other KPIs
Customer advances — upfront cash deposits paid by buyers for equipment ordered but not yet delivered — rose 57.2% from a year ago and $552 million from last quarter, by our math. Over the first nine months of 2026, these deposits generated $4.00 billion of operating cash flow, more than double the $1.65 billion inflow a year ago.
Stock on Caterpillar's own balance sheet rose 17.2% from a year ago, matching the 17.3% rise in revenue. Since the end of 2025, inventories have grown by $4.08 billion as the industrial group builds machines and engines for its expanding order book, absorbing $4.12 billion of operating cash flow over the first nine months.
The diluted share count fell 2.1% from a year ago, by our math, lifting profit per share growth about 2.5 percentage points above net profit growth. The heavy-equipment maker spent $1.2 billion on share buybacks in the third quarter, down from $1.5 billion in the second quarter and $5.0 billion in the first.
🔮 Guidance
Unchanged. The heavy-equipment maker kept its estimated full-year tax rate, excluding one-off items, at 23.0% in the release's tax reconciliation, down from 24.0% at this point in 2025. The lower rate has held steady across all three quarters of 2026.
❓ Key Questions
Did Caterpillar raise its full-year revenue and cash flow targets?
The earnings release contains no forward outlook table. Last quarter's plan called for 15% to 19% full-year sales growth, which by our math leaves only about 7% growth for the fourth quarter after a 21% rise in the first nine months.
How large is the new record backlog, and what is inside?
Chief executive Joe Creed mentioned a record order backlog, topping last quarter's $72.1 billion, without giving a number. Investors need the total dollar figure, the share scheduled beyond 12 months, and the split between data-center power and construction.
How much did dealer inventories change in the third quarter?
Caterpillar cited dealer inventory changes as the main driver of mining sales growth and a contributor in Latin American and Asian construction. Without the exact dollar build, readers cannot tell how much fourth-quarter destocking remains.
What were gross tariff costs before the $128 million refund?
Management previously forecast about $600 million of third-quarter tariff expenses and $2.2 billion for the year. Because Resource Industries margins fell on tariff and material costs, the gross tariff bill shows whether trade headwinds are worsening.
Are the restarted 10-megawatt gas engines shipping in Q4?
Last quarter, Creed committed to bringing 1.5 gigawatts of medium-speed gas engine capacity back online with first shipments in the fourth quarter. With Power Generation retail sales up 75% against 30% revenue growth, adding factory output is critical.
