Caterpillar Q3 2026: sales up 17% to $20.7B, but EPS +46% leans on a tariff refund and a tax lap

In Caterpillar's third quarter of 2026 (the three months to 30 September), sales and revenues rose 17% to $20.682 billion from $17.638 billion. Almost three-quarters of the $3.044 billion increase came from selling more machines and engines ($2.207 billion of volume), with $663 million from higher prices and $58 million from currency. Profit rose 43% to $3.287 billion and diluted earnings per share (profit divided by every share, including those stock awards could create) rose 46% to $7.13. The business really did improve, but part of that 46% came from things that won't repeat. A $128 million tariff refund lifted operating profit, and last year's quarter had carried $95 million of one-off tax charges. Without both, EPS growth was about 36%.

Key figures

Operating margin is the share of sales left after paying to build, sell and develop the products, before interest and tax. Caterpillar's "adjusted" figures remove restructuring costs only ($41 million this quarter, $37 million a year ago). They do not remove the tariff refund. Q3 operating cash flow is our calculation: the nine-month figure of $10.593 billion less the first half's $6.241 billion from the Q2 10-Q.

Over nine months, sales and revenues are up 21% to $58.640 billion and diluted EPS is up 49% to $20.36 from $13.69.

By segment

Segment margin is segment profit as a share of segment sales. Caterpillar now reports Rail inside Resource Industries, and the year-ago figures above are restated on that basis.

Power & Energy (engines, turbines and generators) made $2.143 billion of segment profit, up 31%. Power Generation sales rose 30% to $3.421 billion. The release says the growth came "mainly in turbines and turbine-related services and in large reciprocating engines, primarily in data center applications". Oil and Gas rose 13% to $2.236 billion on gas-compression engines and aftermarket parts. Industrial rose 4%. The segment kept about 39 cents of profit from each extra dollar of sales ($510 million on $1.321 billion).

Construction Industries (excavators, loaders and other building equipment) made $1.831 billion, up 33%. North American sales rose 23%, which the release attributes to selling more machines to end users plus higher prices. Price added $349 million, the most of any segment. It was partly offset by $252 million of higher manufacturing costs, including freight. The segment kept about 37 cents of each extra sales dollar.

Resource Industries (mining trucks, large quarry equipment and now locomotives) is the weak spot. Sales rose 15%, but profit rose only 14% to $622 million and the margin slipped to 13.5%. The segment kept just under 13 cents of each extra sales dollar ($78 million on $616 million), because manufacturing costs rose $208 million. The release says these "primarily reflected higher material costs, including tariffs." Rail sales fell 5% to $832 million on fewer international locomotive deliveries.

Financial Products (Cat Financial, the in-house lender to dealers and customers) made $264 million, up 10%. Loan quality is steady: past-due accounts were 1.31% of the portfolio against 1.47% a year earlier, and net write-offs were $28 million against $40 million. The allowance for credit losses (money set aside for loans that may not be repaid) rose to $332 million, or 0.91% of finance receivables, from 0.84% three months earlier. That is a small step up in caution, not a sign of losses.

What the headline numbers hide

A tariff refund, again. In Q2, Caterpillar booked $392 million of refunds of 2025 tariffs that the US Supreme Court ruled unauthorized (the IEEPA tariffs). Its outlook then assumed no further refunds. Q3 operating profit nonetheless includes another $128 million of IEEPA tariff recoveries. Without it, operating profit was about $4.09 billion, up 34% rather than 38%, on a margin of about 19.8% (our calculation). After tax at the 23% underlying rate, the refund is worth roughly $0.21 a share.

The prior-year tax charge flatters the comparison. The effective tax rate fell to 22.9% from 26.7%. That is not mainly a lower tax rate this year. Q3 2025 carried a $54 million catch-up charge for a higher full-year rate and a $41 million charge for prior-year estimates. Together that is about $0.20 a share that didn't recur. The underlying rate, excluding those one-off items, was 23.0% against 24.0%.

Putting it together. Pretax profit rose 35% to $4.220 billion. If you remove the refund and apply each year's underlying tax rate, EPS was about $6.91 against $5.07, a gain of roughly 36% (our calculation). Buybacks did a little of the work as well. Diluted shares were 2.1% lower, worth about 2 points of EPS growth. Caterpillar's adjusted EPS of $7.20 only removes restructuring, so it keeps both the refund and the tax comparison.

Two market-driven items pull in opposite directions. Corporate costs fell $131 million, which the release attributes to "a favorable change in fair value adjustments related to deferred compensation plans". Meanwhile other income fell $73 million to $135 million, mainly because of "unfavorable impacts from total return swap contracts". Together they net to about $58 million of help. Both move with financial markets, not machine demand, so neither says much about the underlying business.

Some sales went to dealer shelves, not to customers. Caterpillar sells mostly to independent dealers, so a sale is recorded when a dealer buys, not when an end customer does. The company's own dealer-reported retail statistics (Exhibit 99.2, three-month figures) show where demand is running ahead of or behind shipments:

In Construction, sell-in matched end demand. In mining, Caterpillar shipped much more than dealers resold, and the release confirms dealer inventory changes drove that increase. Power & Energy runs the other way: end-user sales grew twice as fast as Caterpillar's segment sales. Dealer inventory changes also drove volume in Construction's Latin America and Asia/Pacific sales. The dollar amount of dealer stocking isn't in the release. It will be in the 10-Q, which hasn't been filed yet.

Cash flow is strong, but customer deposits carry part of it. Q3 operating cash flow was about $4.35 billion, 1.3 times profit. Of that, $1.43 billion came from higher customer advances (deposits paid before delivery). Without them, cash flow was about 0.9 times profit. Over nine months, receivables used $3.761 billion of cash and inventories $4.118 billion. Inventory on the balance sheet is up 22% since December to $22.214 billion and trade receivables are up 23% to $13.440 billion, slightly ahead of 21% sales growth. That fits a company building to a backlog, not one struggling to sell.

Shareholder payouts exceed free cash flow. Q3 buybacks were $1.223 billion and dividends $749 million (nine-month figures less first-half figures). Over nine months Caterpillar paid out $9.893 billion ($7.745 billion of buybacks and $2.148 billion of dividends). Operating cash flow less both capital-spending lines was $7.367 billion over the same period. Cash fell $2.051 billion to $7.929 billion, and net long-term debt issued was $2.995 billion. That consolidated figure includes Cat Financial's borrowing, which funds its customer loans.

On balance the quarter is flattered. Reported EPS rose 46%, but about 36% once the $128 million tariff refund and last year's $95 million tax charges are set aside. Even that underlying rate is a very strong quarter.

Did last time's read hold up?

Our Q2 report named two tests for whether margins would hold. The first was whether Construction Industries could stay near a 23% segment margin. It did, at 22.9% against 23.3% in Q2. The second was whether Resource Industries could keep more than about 17 cents of each extra sales dollar. It didn't: it kept under 13 cents, as material and tariff costs rose $208 million. Management had also promised "strong sales and revenues growth" for Q3 (+17% delivered) and assumed no further tariff refunds ($128 million arrived anyway). The Q2 10-Q said Construction dealers would add only "slightly" to inventory in Q3. That can't be checked until the 10-Q gives the figure.

Takeaway: Caterpillar's demand is real and still broadening. Sales rose 17% and operating margin rose about 2.5 points even without the tariff refund. But the 46% EPS jump overstates it: about 10 points came from the refund and a soft prior-year tax comparison. Resource Industries is turning sales into profit poorly, and its mining growth rests partly on dealer stocking.

Outlook

The earnings release gives no updated outlook. The CEO cites "strong order rates and a record backlog" but doesn't give the backlog figure. The latest guidance is the Q2 10-Q's: full-year sales growth "in the mid-to-high teens", tariff costs of about $2.2 billion before refunds, a 23.0% underlying tax rate, and a Construction dealer-inventory reduction of more than $1.0 billion in Q4. After nine months at +21%, that guide covers a wide range for Q4. On 2025 sales of $67.6 billion, mid-to-high teens implies Q4 sales of roughly $19–22 billion, from about flat to about +14% on Q4 2025 (our arithmetic). The low end would be a sharp slowdown from Q3.

Our read: Power & Energy is the strongest part of the story. End-user sales up 36%, and up 75% in power generation, are not dealer restocking. Construction is executing well, but Q4 is when the promised dealer destocking hits its reported sales. The number to watch in Q4 is Resource Industries' margin. If it stays near 13.5% while sales grow in the teens, tariffs and material costs are absorbing the price increases. If mining retail stays near +8% while sell-in runs above 20%, the segment's growth will slow when dealers stop stocking. The 10-Q, due in the coming days, will give the backlog and dealer-inventory figures this release leaves out.
