Should Caterpillar’s Tariff Bill Worry You More Than Its Backlog

Caterpillar (CAT) delivered the biggest quarter in its history, with a $72 billion order book behind it-59% of which it expects to ship over the next twelve months. The stock has gained 82.8% on a price basis over the past twelve months against 15.6% for the S&P 500, and still sits about 25% below its 52-week high. Neither the record nor the backlog is the number to watch. That would be the roughly $2.2 billion of tariff costs, before the second-quarter recoveries, that Caterpillar expects to carry in 2026.

Caterpillar's Best Quarter Ever Came With An Expected Tariff Recovery

Sales rose 24% year over year in the second quarter of 2026, and adjusted operating profit margin came in at 21.9%. Management named the reason it beat plan: $392 million of expected federal emergency tariff recoveries, plus tariff costs that ran lower than forecast. Those recoveries sat against roughly $400 million of tariff cost in the same quarter. The expected recovery is part of what that margin is.

And Caterpillar Is Not Counting On A Second Recovery

Caterpillar's outlook does not include any further emergency tariff recoveries in the second half of 2026. Excluding the second-quarter recoveries, Caterpillar now expects around $2.2 billion of tariff costs for 2026, the low end of the range it previously gave. That cost is close to 3% of the $74.7 billion of revenue Caterpillar booked over the past twelve months, and about $600 million of that bill lands in the third quarter of 2026.

Management expects the year-over-year drag to fade in the second half of 2026 as it laps the earlier increases. That is a comparison getting easier, not a cost going away.

Construction Industries Carries Half The Third-Quarter Bill

About half of that third-quarter cost falls on Construction Industries, with a quarter each in Power & Energy and Resource Industries. In the second quarter of 2026, before the expected recoveries, tariffs cost Construction Industries 340 basis points of margin, even as the segment's margin still rose 320 basis points from a year earlier. Construction Industries is also where the sales comparison gets harder. Construction Industries dealer inventory rose in the second quarter of 2026, and Caterpillar expects a reduction of more than $1 billion in the fourth quarter of 2026.

Without The Expected Recoveries, Margin Would Land Near The Bottom Of The Range

Take the recoveries out and management expects full-year 2026 adjusted operating margin near the bottom of its target range, even on the sales outlook it raised in August. That captures the central tension in one line: record sales, a record backlog, and, on that same basis, profitability toward the low end of Caterpillar's target range. Underlying business fundamentals remain solid. The demand behind the backlog is real, with power generation growth driven by large gensets and turbines used in data center applications.

What to watch is narrow. If Construction Industries absorbs its portion of the third-quarter tariff expense and offsets it through price realization while dealers reduce inventory, the margin impact remains manageable. If the segment cannot, the tariff headwind becomes a primary drag on operating leverage. The options market is not pricing an outsized move either way, with implied volatility in the 46th percentile of its trailing one-year range.

So Is The Backlog Enough To Hold You?

Perhaps, but only if you are buying the order book rather than the profit on it. To settle that you would have to judge how long the tariff cost stays and whether Construction Industries can price through it. That is a lot to carry for one industrial name. If you would rather not judge one company's cost line at all, the Trefis High Quality Portfolio is built for that. That portfolio has a track record of outpacing the three major indices.
