5. Caterpillar Inc. (CAT)
The world’s largest construction equipment manufacturer generated $17.64 billion in Q3 revenue, marking 9.5% year-over-year growth driven by robust equipment sales. Operating margin compressed from 19.5% to 17.3% due to elevated manufacturing costs and tariff impacts.
With a market capitalization of $288.3 billion, Caterpillar commands a premium valuation at 27x forward earnings and 21.6x EV/EBITDA. The company maintains exceptional return on equity of 46.3% and generated $4.05 billion in adjusted EBITDA during the quarter.
