Dealer Inventory: The Buffer Caterpillar Does Not OwnNarrow moat

Caterpillar (CAT) — moat facet

In the first half of 2026 dealers added $2.6 billion of Caterpillar inventory, which is why Construction Industries sales grew 35% while dealer sales to users grew 22%.

Caterpillar's reported sales are, for most machines, sales to its dealers, and the dealers decide how many machines to keep on the lot. That buffer can add or subtract billions from a year's revenue without any change in what contractors are buying.

Two years of machine destocking, then a restock.

The company says so plainly: "Dealers are independent, and the reasons for changes in their inventory levels vary"1. In 2024 total dealer inventory rose $400 million while machine dealer inventory fell $700 million; in 2025 total dealer inventory rose $900 million while machine inventory fell $500 million2. The machine figure matters most for Construction Industries.

In 2026 the buffer turned into a tailwind. Total dealer inventory rose $2.6 billion in the first half, with Construction Industries' dealer inventory up $1.9 billion against a $400 million decrease in the first half of 20253. Caterpillar expects a decrease of over $1.0 billion in Construction Industries' dealer inventory in the fourth quarter, but still a higher level at year-end 2026 than at year-end 20254.

That is why the company publishes retail statistics: sales to users are what dealers actually sold to customers. In the second quarter of 2026 Construction Industries' total sales rose 35%5, while its sales to users rose 22%6. The difference is the lot filling up.

The company knows the gap between its sales and dealers' sales matters, which is why it publishes the retail figures at all. The statistics are based on unaudited reports voluntarily provided by independent dealers and are not subject to Caterpillar's internal controls, and the company says they are intended only to convey an approximate indication of trends7.

The gap between shipments and sales to users is the thing to track. A few quarters of restocking after two years of destocking is normal; if dealers are still adding inventory when sales to users stop growing, the next year will begin with a destock that Caterpillar has to absorb.

Moat trajectory: Holding steady

Restock after two years of machine destocking; year-end 2026 CI inventory expected higher.

The number that tests this moat
Reported
Dealer inventory change, latest half year
+$2.6bn in H1 2026 (Construction Industries +$1.9bn)

The share of shipments that has not reached a user; a build that continues while sales to users slow means a destock ahead.
