Caterpillar profit surges on AI data-center demand, but shares sink on spending fears

Caterpillar reported a sharp jump in third-quarter profit before markets opened on Thursday, with revenue climbing 17 percent and operating margins reaching their highest level in years, powered in part by surging sales of generators and turbines used to run artificial-intelligence data centers. The construction and mining equipment maker beat Wall Street's profit and revenue estimates for the fourth straight quarter. Its stock fell anyway, dropping more than 8 percent in early trading as investors, rattled by a broader wave of worry over the sustainability of debt-funded AI spending, sold off machinery and industrial stocks tied to the data-center buildout.

The results, disclosed in a filing with the Securities and Exchange Commission, mark one of the strongest quarters in Caterpillar's recent history and underline how deeply the AI infrastructure boom has reached into heavy manufacturing, an industry once defined almost entirely by excavators, bulldozers and mining trucks.

A record quarter by several measures

Sales and revenues totaled $20.7 billion for the three months ended September 30, up from $17.6 billion a year earlier, according to the earnings release Caterpillar attached to a Form 8-K filed with regulators. Profit per share came to $7.13, compared with $4.88 in the third quarter of 2025; on an adjusted basis, which excludes about $41 million in pretax restructuring costs, profit per share was $7.20, up from $4.95 a year earlier.

Operating profit rose 38 percent, to $4.214 billion, pushing the operating margin to 20.4 percent from 17.3 percent a year ago. The results topped Wall Street's consensus estimate of roughly $7.03 a share and edged past revenue forecasts of about $20.6 billion, according to an Investing.com summary of the results.

All four of Caterpillar's segments grew from a year earlier:

• Power & Energy, the company's largest segment, posted sales of $8.784 billion, up 18 percent, with a segment profit margin of 24.4 percent.
• Construction Industries sales rose 18 percent, to $7.983 billion, though the segment absorbed $252 million in unfavorable manufacturing costs, including higher freight expenses.
• Resource Industries, which sells mining equipment, grew 15 percent, to $4.615 billion, while absorbing $208 million of unfavorable costs that the company said "primarily reflected higher material costs, including tariffs."
• Financial Products, Caterpillar's lending arm, grew 13 percent, to $1.028 billion.

Within Power & Energy, sales tied to power generation equipment rose 30 percent, to $3.421 billion, a jump the company attributed mainly to turbines, turbine-related services and large reciprocating engines sold "primarily in data center applications." Hyperscale computing operators have been racing to secure backup and primary power sources for AI server farms, and Caterpillar has positioned itself as one of the industrial beneficiaries of that scramble.

The company generated $4.4 billion in enterprise operating cash flow during the quarter and ended it with $7.9 billion of enterprise cash on hand. It returned about $2 billion to shareholders, including roughly $1.2 billion in share repurchases and $0.7 billion in dividends.

Tariffs still a drag, but easing

Tariffs tied to the administration's use of emergency economic powers have weighed on Caterpillar's manufacturing costs for more than a year. The company's most recent quarterly filing, covering the second quarter, said its cumulative tariff costs under that authority had reached roughly $1.0 billion since they took effect, before a $392 million recovery booked in the second quarter. The third-quarter release shows a further $128 million of tariff recoveries flowing into operating profit, a sign the financial drag has begun to ease even as elevated material and freight costs continue to show up in the Construction Industries and Resource Industries segments.

Going into the report, analysts had penciled in roughly $600 million of tariff-related costs for the third quarter alone and about $2.2 billion for all of 2026, according to a preview published ahead of the earnings report. The same preview noted that Caterpillar's order backlog had swelled to a record $72 billion at the end of the second quarter, up $9 billion in three months, with 59 percent of it expected to ship within a year — a pipeline that Chief Executive Joe Creed cited again on Thursday as evidence the company's end markets remain unusually durable. That same preview put Wall Street's consensus for full-year 2026 at roughly $79.6 billion in revenue and about $27.33 a share in adjusted earnings, which would mark growth of nearly 18 percent and more than 43 percent, respectively, from 2025.

Caterpillar, which moved its global headquarters from Deerfield, Illinois, to Irving, Texas, in 2022, has now topped profit estimates in each of the last several quarters even as tariffs tied to the International Emergency Economic Powers Act have repeatedly cut into its manufacturing margins. Thursday's filing shows that drag beginning to narrow as recoveries flow back through the income statement, even as raw-material and freight costs tied to tariffs continue to show up line by line in the construction and mining segments.

"Our third-quarter results reflect the durability of our end markets, with strong order rates and a record backlog," said Joe Creed, Caterpillar's chairman and chief executive.

A beat that the market punished anyway

Despite the across-the-board beat, Caterpillar shares sank more than 10 percent in premarket trading and remained down roughly 8 percent by mid-morning, trading near $656, according to a report on the stock's reaction. The decline was not, by most accounts, a verdict on Caterpillar's own numbers. Instead, the report said, AI-exposed stocks broadly sold off ahead of Thursday's open after results from a slew of megacap technology companies "revived worries over the sustainability of increasingly debt-driven spending on data centers and chips." Caterpillar, as a major supplier of the heavy equipment and power generation gear used to build that infrastructure, was swept into the retreat alongside semiconductor, networking and power-equipment stocks.

The reaction fits a pattern analysts have flagged for months: Caterpillar has beaten per-share earnings estimates in each of its last several quarters, and those beats have not reliably translated into stock gains, as investors increasingly treat the company as a proxy for the broader AI-capital-spending trade rather than judge it purely on its own industrial fundamentals. Shares had already pulled back roughly 15 percent over the month leading into Thursday's report, even as they remained up sharply for the year.

Who is affected

The quarter's results carry implications well beyond Caterpillar's own shareholders. Construction firms, mining operators and data-center developers that depend on Caterpillar equipment benefit from a company investing aggressively to keep pace with demand, while the record backlog suggests delivery times for some machines and generators could remain extended into next year. Suppliers and factory workers across Caterpillar's manufacturing network, which spans Illinois, Texas and other states, stand to benefit from sustained production volumes tied to that backlog. Because Caterpillar is a component of the Dow Jones Industrial Average, Thursday's double-digit decline also weighed directly on index funds and other portfolios tracking that benchmark, independent of the company's own underlying performance. More broadly, investors in industrial and power-equipment stocks were reminded that their holdings are now closely correlated with sentiment about Big Tech's AI capital spending, even when the underlying industrial business is performing well.

What comes next

Caterpillar did not publish numerical guidance for the fourth quarter or full year in Thursday's release, saying only that it would discuss adjusted profit expectations, excluding pension remeasurement gains or losses, on its earnings call. Investors will be watching for whether tariff recoveries continue to offset cost pressure, whether the backlog keeps growing as new orders come in, and whether demand for turbines and generators tied to data centers holds up if hyperscale operators show any sign of slowing capital spending. The next test of that question will come from the technology companies themselves in their coming earnings reports and capital-spending disclosures, which investors are likely to parse at least as closely as Caterpillar's own numbers for clues about how long the current equipment-buying cycle can last.
