Caterpillar Stock Is Waiting On One Answer

For questions about this article or underlying research, email help@trefis.com.

Caterpillar (CAT) has a record backlog, the orders customers have placed that it has not yet filled. Management says how fast it can add factory capacity is the main limit on growth in Power and Energy, the business that builds its large engines and turbines. Caterpillar’s orders now run ahead of that capacity, and how far ahead is the open issue.

Caterpillar Is Taking Engine Orders Into 2029

Customers face the longest wait for the biggest products. On its October 29, 2026 call, management said Caterpillar is taking some large engine orders as far out as 2029 and turbine orders into 2030, while smaller engines have much shorter lead times. A backlog turns into revenue only when the product ships: an engine ordered today for delivery in 2029, for example, sits in the backlog for years before it adds anything to sales.

On that third-quarter 2026 call, analysts asked how many of the new orders were for those later years, and whether 2027 sales growth could run above Caterpillar’s 6% to 9% yearly revenue growth target, with the backlog where it is. On the first, management said the answer depends on the product.

Caterpillar’s Backlog Equals A Year Of Sales

The backlog reached a record $78 billion at the end of the third quarter, close to the $77.8 billion of revenue Caterpillar reported for the twelve months to September 30, 2026. That backlog was 96% larger than a year earlier.

The capacity limit sits in Power and Energy, which is also Caterpillar’s largest segment. It had $32.2 billion of revenue in fiscal 2025, a figure that can include sales to other Caterpillar segments. That was 11.6% more than in fiscal 2024, a faster pace than Construction Industries or Resource Industries managed. Construction Industries revenue fell 1.6%, and Resource Industries revenue rose 0.7%.

What Caterpillar Has Said About Building Faster

Management has said it plans to raise its capacity for large engines to nearly three times the 2024 level by 2030. As one step, the company will use part of its Winston-Salem, North Carolina plant, which currently makes locomotive engines, as a second assembly and test site for its 3600 series large engine. Management also said capacity arrives step by step rather than all at once, with more product shipped each quarter, and that the ramp has brought operational challenges and inefficiencies it expects to work through.

For now, management’s sales outlook covers 2026: it expects moderate growth in the fourth quarter from a year earlier, against a strong fourth quarter of 2025. Management said it will say a lot more about 2027 at its next report. The figure to watch in that report is the share of the backlog Caterpillar expects to sell within the next twelve months, which management put at 58% on the October call.
