Caterpillar Stock Growth Drives Premium Valuation Among Peers

Caterpillar (CAT) stock is trading at 36.0 times its earnings, making it more expensive than most of its machinery and heavy equipment rivals. Despite this, it is not the priciest in its peer group, having returned 74.4% over the past year, the highest among six comparable companies. The premium price reflects Caterpillar's strong growth, with sales rising 18.4% over the last twelve months, outpacing Deere's (DE) 8.0% growth. Both companies boast similar operating margins, but Deere trades at a slightly higher P/E of 37.8.

The three cheaper stocks in the group, PACCAR, Cummins, and Oshkosh, showed weaker sales growth and lower operating margins. Terex, though growing faster at 29.2%, reported an operating loss in Q1 2026, skewing its P/E to 43.4.

Caterpillar's growth is driven by all three of its main business segments. In Q2 2026, sales hit $20.5 billion, up 24% year-over-year, with Construction Industries leading at a 35% increase. The company's backlog reached $72 billion, up 92%, indicating strong future demand. Management forecasts mid to high teens sales growth for full-year 2026, though risks include maintaining margins and sustaining growth.

Caterpillar's stock price suggests expectations of continued growth without margin erosion. The company's full-year 2026 results will be crucial in determining if it can turn growth into profit, ideally restoring its operating margin to above 18.2%.
