The 2020-2023 cycle was different in character but identical in management response. The US Infrastructure Investment and Jobs Act, combined with similar programmes in Europe and across Asia, unleashed the largest wave of public construction spending in decades. Caterpillar's Construction Industries segment, which accounts for roughly 40% of group revenue, was the primary beneficiary.
Revenue surged from $51 billion in 2021 to $67.1 billion in 2023, a 32% increase over two years. The remarkable part was the margin trajectory. Operating income grew from $6.9 billion to $12.7 billion over the same period, implying operating margins expanded from 13.5% to nearly 19%. That margin expansion, on revenue growth of 32%, tells you that essentially all the incremental revenue dropped through at substantially higher margins than the base business.
How? Pricing power and operating leverage on a fixed cost base. Caterpillar raised equipment prices by 15-20% cumulatively over 2022-2023, citing supply chain costs and materials inflation. Dealers accepted the increases because equipment availability was constrained and project timelines were fixed. When costs subsequently moderated, the pricing stuck. The pattern is identical to what we see at Coca-Cola and Deere: industrial companies with dominant market positions convert cost inflation cycles into permanent margin expansion.
The 2011-2014 cycle, by contrast, saw Caterpillar add roughly $3 billion in manufacturing capacity that became severely underutilised when Chinese infrastructure demand collapsed. Management's refusal to repeat that mistake during the 2020-2023 boom is the single most important factor in the current valuation.
