Caterpillar's stock opened 11.1% higher on Tuesday, touched a 12.7% gain in the first minutes of trading, fell to up 4.4% by mid-morning, and sat 6.4% higher at midday. The session was not finished at the time of writing, so treat every one of those figures as a timestamp rather than an outcome.
What happened in between is the useful part. The company reported record quarterly sales and revenues of $20.543 billion, up 24%, adjusted profit of $8.17 a share against a consensus clustered near $6.20, and a record backlog of $72.1 billion. Traders spent the first hour taking that apart. The reasons sit inside the release, and they are mostly about what the surprise was made of.
The beat has more tariff in it than the headline shows
Caterpillar's adjusted measures exclude one thing: restructuring. They do not exclude tariffs. The release states that second-quarter operating profit included $392 million of expected recoveries under the International Emergency Economic Powers Act. That amount is inside both the $7.77 GAAP figure and the $8.17 adjusted figure.
On the call, management put second-quarter tariff costs at roughly $400 million, against the $700 million it had projected in April. So the tariff line moved about $692 million in Caterpillar's favor relative to its own spring framework, counting the recovery and the lower cost together. At the company's stated 23% annual effective rate on 462.5 million diluted shares, that is worth roughly $1.15 a share. The consensus beat was $1.92 to $2.00, depending on whose tally you use. The arithmetic is ours, and the tax assumption is ours, because the release discloses no tax effect specific to the recovery.
Two more items belong in the same column. Other income rose to $398 million from $84 million, which the company attributes to currency, total return swaps, and investment and interest income. Equity in the profit of unconsolidated affiliates rose to $90 million from $7 million. Together those add about $0.66 a share. None of the three is excluded from adjusted results.
There is an asymmetry worth naming, because it is easy to get backwards. Per the call, the tariff cost landed in the segments, at 340 basis points of margin in Construction Industries, 260 in Resource Industries and 90 in Power and Energy. The release says the majority of the recovery landed in corporate items. Segment margins therefore carry the cost without the offset, and the consolidated 20.9% operating margin carries the offset without the full cost. Any sentence that pairs segment margin expansion with the consolidated figure needs that caveat attached.
Construction Industries outgrew the data-center segment
The dominant framing on Tuesday was data centers. The segment table does not support the weighting. Power and Energy, which houses the data-center business, grew 17% and added $1.201 billion of sales. Construction Industries grew 35% and added $2.156 billion, nearly twice as much. Power and Energy was the slowest-growing of the three primary segments.
The data-center driver is real inside the segment. Power Generation sales rose 29% to $3.098 billion, and the release credits large reciprocating engines and turbines used primarily in data-center applications. Management said it is restarting 10-megawatt gas engine production, with 1.5 gigawatts of capacity expected online by the fourth quarter. But Power Generation is 38% of Power and Energy sales. Oil and Gas grew 9%. Industrial grew 9%. Power and Energy sales in Latin America fell 16%.
Construction Industries also overtook Power and Energy as the largest segment by sales, at $8.346 billion against $8.238 billion, having been $847 million smaller a year earlier. That reordering happened in four quarters.
One qualification on the construction number. North American Construction Industries sales rose 50%. The release says the volume increase came from higher sales to end users and from changes in dealer inventories, without splitting the two. The call supplied the missing figure: Construction Industries sales to users grew 22%, a sixth consecutive quarter of growth. Reported segment sales grew 35%. The gap between those two rates is price realization plus a dealer restock. End-user demand grew, and it grew more slowly than the shipments.
The record backlog is also a slow one
The $72.1 billion backlog is a real forward signal, and it is corroborated inside the balance sheet. Customer advances rose 44% in six months, to $4.777 billion. Chief Executive Joe Creed told the call that no customers have backed off and that the backlog is getting more extended. Neither the backlog figure nor the guidance appears in the press release, so both are call-sourced rather than issuer-published.
The extension cuts in two directions. Asked about conversion, management said Power and Energy is "much more extended" on the share delivered in the next twelve months. A record book weighted toward the slowest-converting segment supports the multi-year case more than the next-four-quarters case.
The guidance arithmetic points the same way. Caterpillar raised full-year revenue growth to a mid-to-high-teens rate from low-double-digit. Against 2025 revenue of $67.589 billion and first-half 2026 revenue of $37.958 billion, a 16% to 19% full-year outcome implies second-half growth of roughly 10% to 15.5%. First-half growth was 23.2%. Management said it is bullish on the back half. The range it guided to embeds a slowdown from what it just delivered.
The operating leverage is real, and it is the bull case
None of the above makes the quarter hollow, and the strongest counterargument is a single line. Cost of goods sold rose 18.3% while sales and revenues rose 24.0%. That gap is not a tariff timing item, an other-income swing or a restock. It is volume running through a fixed cost base, and it is the cleanest number in the release.
Volume contributed $3.113 billion of the $3.974 billion revenue increase, price $595 million and currency $199 million. So roughly 78% of the growth is volume and 15% is price, which undercuts both the all-price and the all-volume readings. Construction Industries segment profit rose 57% and its margin reached 23.3% from 20.1%. It did that while absorbing 340 basis points of tariff cost. The effective tax rate was flat at 23.1%, so no rate tailwind sits in the comparison. Cat Financial's past dues improved to 1.31% from 1.62%. Credit is not deteriorating underneath the machine sales.
Resource Industries is the exception. Its margin moved 0.4 points, to 14.9%, held back by $158 million of unfavorable manufacturing costs. Margin expansion was not broad-based.
What the second half has to prove
Caterpillar returned $7.921 billion to shareholders in the first half, against first-half profit of $6.142 billion. That is about 129% of earnings, and shareholders' equity fell 9% in six months as a result. Inventories rose 13.7% and trade receivables 20.8% over the same period. The release comments on none of it. State the figures and watch them.
Three things would strengthen the case that this is a step-change in earnings power. Construction Industries sales to users converging back toward reported segment sales. Growth outside North America, which supplied about 82% of the consolidated revenue increase. Asia Pacific rose 4%, and management conceded the region came in below its own expectations. And segment margins holding once the tariff recovery stops flattering corporate items.
Three things would validate the skeptics. A second-half revenue path at the low end of the implied 10% range. Any reversal in the tariff line, which management called fluid and which the release names as a risk factor. A backlog that grows in dollars while the share converting within twelve months keeps stretching.
The shares say the debate is live. Even after Tuesday's gain, Caterpillar traded about 18% below its 52-week high and about 4% below its 50-day average. It has roughly doubled from its 52-week low, and it trades near 38 times trailing twelve-month GAAP earnings. The power-equipment complex moved with it. Vertiv was up 4.4% and Quanta Services 3.5% at the same snapshot.
Before the print, Caterpillar had to prove the AI buildout was reaching its order book. The backlog says it has. What it has to prove next is that the earnings arrive without the tariff line doing a share of the work.
