The Caterpillar Q3 results were strong on almost every line, and the stock fell anyway. In its third-quarter release on Oct. 29, the equipment maker reported sales and revenues of $20.7 billion, up 17% from $17.6 billion a year earlier, and adjusted earnings of $7.20 a share, up 45%. A summary of the report by Pomegra says the shares closed near $661.54, down about 7%.
The numbers behind the Caterpillar Q3 results
Higher volume added $2.2 billion to sales and price realization contributed $663 million. The adjusted operating margin was 20.6%, up from 17.5% a year earlier. The order backlog reached a record $78.1 billion, roughly $38 billion higher than a year ago, and it was the fourth straight quarter of sequential growth across all three primary segments.
The standout was Power & Energy, where revenue rose 18% to $8.78 billion and segment profit rose 31% to $2.14 billion. Retail sales in that segment grew 36%. The summary ties part of that demand to power needs at AI data centers, which fits the capital spending on display this week at the biggest technology companies and in the GDP report’s jump in tech-equipment spending.
Why the stock fell
The reason is tariffs and expectations. Caterpillar’s tariff costs were about $600 million in the third quarter, not counting $128 million of recoveries tied to the IEEPA tariffs, and the company expects about $600 million more in the fourth quarter. That brings full-year 2026 tariff costs to roughly $2.2 billion before those recoveries.
The company kept its outlook unchanged: sales growth in the mid-to-high teens and an adjusted operating margin near the bottom of its target range. After a record backlog, investors had expected a raise, and the stock had already fallen about 10% in the prior month, per the summary. Shares dropped as much as 9% to 10% during the session.
What the backlog does and does not say
A backlog is orders not yet filled, so a record $78.1 billion means demand has run ahead of deliveries. That supports future sales, but it is not profit. The margin question is whether price increases keep outrunning tariff costs. The company’s own guidance, with margin near the bottom of its target range, suggests management is not yet willing to promise that.
The tariff backdrop is also shifting. The administration’s recent changes to tariffs on Canadian goods show how quickly input costs can move for manufacturers that cross the border.
What to watch next
The next tests are the fourth-quarter report and the 2027 outlook. The things to look for are whether tariff costs hold near $600 million a quarter, whether price increases keep offsetting them, and whether the backlog keeps growing once the data center build-out slows.
Editor’s take
Watch the margin guidance, not the backlog. A record backlog tells investors that customers want the machines. An unchanged margin forecast, set near the bottom of the target range, tells them that tariffs are absorbing much of the benefit. Until Caterpillar shows it can price through the $2.2 billion tariff bill, the market is likely to treat strong orders as necessary but not sufficient.
