Caterpillar's Valuation Hinges on Margin Expansion and Earnings Growth

Caterpillar (CAT) has seen its stock price nearly double over the past year, currently trading around $820 per share. This represents a steep multiple of about 36 times its adjusted earnings over the last twelve months.

This valuation seems high for a company that makes construction equipment and engines, but it's worth noting that the S&P 500 returned about 19% over the same period, so Caterpillar has outperformed the market. However, the stock is now trading around 23% below its 52-week high.

Analysts expect earnings to grow significantly in the coming years, with estimates suggesting a growth rate of about 18.4% per year from 2026 to 2027. This would imply that earnings will be about 40% higher than current levels by 2027. Meanwhile, revenue is expected to grow at a slower pace of around 11.8% per year over the same period.

The market's assumption that margins will expand in order for this growth to occur is a key factor in the stock's valuation. However, Caterpillar's current operating margin of 17.5% is below its three-year average of 18.7%. Management has guided towards an increase in adjusted operating margin for full-year 2026, but it remains to be seen whether margins will expand as expected.
