Caterpillar posted its first $20bn quarter with sales up 24% to $20.543bn and diluted EPS of $7.77, but a one-off $392m tariff refund and $1.9bn of first-half dealer stocking flatter a margin management expects to face headwinds in the second half.

The first $20 billion quarter — and the first one where tariffs paid Caterpillar back
Caterpillar's second quarter of 2026 (the three months to 30 June 2026) was the largest in the company's history by sales: $20.543 billion, up $3.974 billion or 24% on the $16.569 billion it booked a year earlier. Profit rose faster still, to $3.593 billion from $2.179 billion, and diluted earnings per share — the share of profit attributable to each share outstanding — reached $7.77 against $4.62.
Two things are worth separating before reading anything else into those numbers. The first is that the growth is genuinely volume-led: of the $3.974 billion sales increase, $3.1 billion came from selling more machines and engines, $595 million from charging more for them (what Caterpillar calls "price realization"), and $199 million from currency translation — the accounting effect of converting sales made in euros, Australian dollars and Brazilian reais back into US dollars at more favourable rates than last year. That is a healthy mix; currency did roughly 5% of the work.
The second is a one-off. Operating profit of $4.295 billion includes $392 million of expected tariff refunds that have nothing to do with how many excavators Caterpillar sold.

Operating profit margin is the share of sales left after the cost of building and selling the product, before interest and tax. "Adjusted" figures are Caterpillar's own, and strip out restructuring costs only.
The tariff refund is real money, but it is not operating performance
On 20 February 2026 the US Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) were unauthorised. Caterpillar states it had paid roughly $1.0 billion in IEEPA tariffs across 2025 and into 2026 before US Customs and Border Protection stopped collecting them. During Q2, CBP opened a claims system (CAPE), and Caterpillar booked $392 million of recoveries it judged probable — recorded as a credit inside cost of goods sold, which is why it lands in operating profit rather than in a separate line.
That placement matters for anyone comparing quarters:
Strip the $392 million out and operating profit was about $3.90 billion, up 36% rather than 50%, on a margin of roughly 19.0% rather than 20.9% — still a large improvement on last year's 17.3%, but a different-looking one.
The recovery flows through to the bottom line too. At the quarter's 23.1% effective tax rate it is worth roughly $0.65 a share (our arithmetic from the disclosed figures, not a company-stated number) — so adjusted EPS of $8.17 would have been closer to $7.50 without it. Caterpillar's "adjusted" definition excludes restructuring but not the tariff recovery, so the adjusted number is flattered here.
Management explicitly does not expect more of this: the outlook "does not include any additional IEEPA tariff recoveries in the second half of 2026," and the company is still assessing whether it can claim the remaining amounts it paid.
Meanwhile the tariffs Caterpillar still pays have not gone away. The company guides to roughly $2.2 billion of tariff costs for full-year 2026 excluding the recoveries, with about $600 million in Q3 alone — half of it landing in Construction Industries, and a quarter each in Power & Energy and Resource Industries.
Takeaway: The 24% sales growth is real and volume-driven, but two items flatter the profit line that will not repeat: a $392 million tariff refund that management says will not recur in the second half, and $1.9 billion of first-half stocking into dealer lots that Caterpillar itself expects to reverse — it guides to Construction Industries' dealer inventory falling by over $1.0 billion in Q4. Underlying operating margin was closer to 19.0% than the reported 20.9%, and the second half faces a dealer-inventory headwind the first half enjoyed as a tailwind.

Construction Industries was the swing factor: sales up $2.156 billion on "higher sales volume of $1.8 billion and favorable price realization of $309 million," with segment profit up 57% to $1.947 billion and margin up 3.2 points. Note what the filing says drove North American volume — "higher sales of equipment to end users and by the impact from changes in dealer inventories." Both. That second half of the sentence is the caveat developed below.
Power & Energy remains the structural story. Power Generation sales rose 29% to $3.098 billion, and the filing attributes it to "large reciprocating engines and in turbines and turbine-related services, primarily in data center applications" — the AI and cloud build-out translating into orders for the generators and turbines that keep data centres supplied. Oil and Gas grew a more modest 9% to $2.044 billion, with gains in gas-compression engines and aftermarket parts partly offset by weaker well-servicing engine sales. Segment margin improved to 24.6% as $457 million of volume profit and $212 million of pricing outran $149 million of unfavourable manufacturing costs.
Resource Industries (mining, heavy construction, quarry and aggregates, plus rail) grew sales 20% but converted least of it: profit up only 23%, and margin up just 0.4 points to 14.9%, because $269 million of volume profit was substantially eaten by $158 million of unfavourable manufacturing costs. Rail sales rose 15% on "higher international locomotive deliveries." This segment also absorbed the $733 million acquisition of RPMGlobal, an Australian mining-software company closed on 17 February 2026, of which $546 million was goodwill — an intangible accounting entry representing what was paid above the value of identifiable assets.
Financial Products, Caterpillar's in-house lender, earned $328 million of segment profit, up 32%, with credit quality improving: past-due accounts at Cat Financial were 1.31% of the portfolio versus 1.62% a year earlier, and the allowance for credit losses sat at 0.84% of finance receivables. Nothing in the customer base is showing stress.
The dealer inventory question
Caterpillar sells most machines to independent dealers, who then sell to end users. When dealers add to their own stock, Caterpillar books a sale that no end customer has yet bought — growth borrowed from a later quarter.
Total dealer inventory rose $600 million in Q2 2026, against a $100 million rise in Q2 2025.
Within that, Construction Industries' dealer inventory rose $400 million, versus a $300 million decrease a year ago — a $700 million year-over-year swing in a segment whose sales rose $2.156 billion.
Across the first half the gap is wider still: dealer inventory up $2.6 billion in H1 2026 versus up $200 million in H1 2025, with Construction Industries accounting for a $1.9 billion build against a $400 million drawdown last year.
Management is not hiding this. The outlook states it expects "a more typical decrease in Construction Industries' dealer inventory of over $1.0 billion in the fourth quarter of 2026" and, as a result, "an unfavorable impact from changes in dealer inventories for Construction Industries' sales volume in the second half of 2026 as compared to the second half of 2025." For Q3 specifically it expects only "a slight increase in dealer inventory... modestly lower than the increase in the third quarter of 2025."
Backlog nearly doubled
The single most striking number in the filing is not on the income statement. Firm order backlog reached $72.1 billion at 30 June 2026, up $9.4 billion in three months and up from $37.5 billion a year earlier — a 92% increase. The largest sequential increase was in Power & Energy, and about $29.2 billion of the total is not expected to be filled within twelve months (against $10.3 billion of the year-earlier backlog).
That long tail is the point: a backlog stretching well beyond a year, concentrated in power generation, is a different asset from a construction order book that turns in a quarter. It also explains the capacity spending — Caterpillar is "progressing on our capacity expansion plans," expects to "increase our throughput in the second half of 2026," and guides to roughly $3.5 billion of capital expenditure this year.
Below the operating line, and cash
Not all of the profit jump was operational. Other income rose to $398 million from $84 million, a $314 million swing the filing attributes to "favorable impacts from foreign currency, total return swap contracts and investment and interest income." That is roughly 18% of the $1.74 billion increase in pre-tax profit, and it is the kind of item that can reverse. The effective tax rate was essentially flat at 23.1% versus 23.0%.
Buybacks contributed too: diluted share count fell 1.9% year over year, which is why EPS grew 68% while profit grew 65%. Caterpillar generated $4.4 billion of enterprise operating cash flow in the quarter, ended it with $6.7 billion of enterprise cash, and returned $2.2 billion to shareholders — $1.5 billion in repurchases and $0.7 billion in dividends. Restructuring costs of $202 million pre-tax ($0.40 a share) included $139 million from divesting certain non-US entities, against a full-year restructuring guide of $300–350 million.
Outlook
For the third quarter, management expects "strong sales and revenues growth" with higher volume and favourable pricing in all three primary segments, partly offset by unfavourable manufacturing costs and higher selling, general, administrative and R&D spending. It flags that Resource Industries' pricing benefit will be smaller than in Q2, and that Construction Industries' volume gain will be partly offset by the dealer-inventory effect.
For the full year, Caterpillar now guides to sales and revenues growth in the mid-to-high teens — a raise in tone from a company that entered 2026 facing an unresolved tariff regime. Services revenues are expected to grow, capital expenditure is about $3.5 billion, and the estimated annual effective tax rate is 23.0% excluding discrete items.
Our read on trajectory. The demand signal is strong and, in Power & Energy, structurally durable — a backlog that nearly doubled with the largest increase in the segment selling into data centres is hard to explain away as a restocking artefact. But the reported second-quarter margin is the high-water mark on current disclosure: the $392 million tariff credit will not repeat, roughly $2.2 billion of tariff cost remains in the 2026 plan, manufacturing costs are running unfavourable in two of three segments as capacity ramps, and $1.9 billion of first-half dealer stocking in Construction Industries is scheduled to unwind. The most useful question for the next two quarters is whether Construction Industries can hold a 23%-plus segment margin while its dealers destock — and whether Resource Industries, which converted the least of its growth into profit, can stop giving back volume gains to manufacturing costs.
