Caterpillar (CAT) Stock Drops As Q3 Earnings Meet Backlog Doubts

Simply Wall St · 2d ago

Caterpillar just dropped its Q3 2026 scorecard and the stock did not like it. Shares fell 3.8% today to US$622.75, adding to a weak 30 day stretch, even as the company posted US$20.7b in sales and adjusted EPS of US$7.20. The emotional driver was not the headline growth. It was the market trying to reconcile a selloff with a quarter built on a record US$78b backlog and a 20.6% adjusted operating margin, highlighting a classic sentiment clash between short term worry and hard construction and machinery cash flow.

Love Caterpillar’s fat 20.6% operating margin but uneasy about a stock that sells off even with a US$78b backlog on the books? Check out the 30 resilient stocks with low risk scores to compare CAT against businesses screened for resilience and steadier risk profiles.

Q3 2026 Earnings Summary

  • Revenue (Q3 2026 vs. Q3 2025): US$20.68b vs. US$17.64b (up about 17%)

Caterpillar’s backlog nearly doubled and now stretches out to 2030. Ask Charlie what makes Caterpillar’s record $78B backlog actually durable.

Caterpillar’s Bull Story Meets Real Backlog Milestones

Bullish commentary argues Caterpillar can shift from one off mega projects to a steadier, services heavy earnings base. That view hinges on execution.

"Long duration framework agreements with large data center operators and orders that already extend into 2029 and 2030 create room for Caterpillar to layer service contracts, software and monitoring on top of installed reciprocating engines and turbines."

Q3 shows that scaffolding in place. Power & Energy is now the biggest segment, driven by AI data center sets, and total backlog has reached US$78b, almost double a year earlier, with orders on some engines and turbines stretching into 2029 to 2030.

Caterpillar Bear Case: Costs Bite, Orders Still Clear

The bear view argues Caterpillar’s expansion will leave it with bloated overhead and squeezed profitability if data center projects slow or hit regulatory walls.

"Investments in autonomy, AI partnerships and a US$100 million workforce training commitment increase SG&A and R&D. If adoption of these technologies in mining, construction and power does not keep pace with spending, the drag on operating margin and earnings could persist longer than current expectations assume."

Fresh numbers cut against that timing. Adjusted operating margin of 20.6% and MP&E free cash flow of US$3.8b show the extra spend is still being absorbed. Milestones missed sit more in sentiment. Q3 revenue landed below expectations and Q4 guidance for only moderate growth, plus the share price drop and muted margin outlook, keep that cost risk alive in investors’ minds.

Hunt For Quiet Dislocations

Caterpillar recently showed that strong backlogs and healthy margins can still mean a volatile share price. The real opportunity sits in spotting stocks that could be undervalued before sentiment catches up.

  • Company 1 - 30% below our estimate - sell AI-focused networking hardware and cloud infrastructure on recurring, consumption-based terms.
  • Company 2 - 38% below our estimate - build out manufacturing and supply capacity for higher margin protective films and installation services.
  • Company 3 - 48% below our estimate - convert long-duration, technology-heavy building projects into design, installation and remote monitoring revenue streams.
