Caterpillar Inc. (CAT) | The Buildout — AI Infrastructure

The Verdict

Caterpillar makes construction and mining equipment, off-highway diesel and natural gas engines, industrial gas turbines, and diesel-electric locomotives. In the AI infrastructure buildout, its Power & Energy segment supplies the large gas reciprocating gensets and turbines that deliver prime and backup power to data centers; those installations then produce decades of aftermarket service revenue.

Earnings Beat

Q2 2026 sales and revenues were $20.5 billion, up 24% y/y and above $20 billion for the first time in company history. Adjusted operating profit margin was 21.9%, up 430 bps y/y, helped by $392 million of expected IEEPA tariff recoveries. Adjusted profit per share was $8.17, up 73% y/y, while GAAP EPS was $7.77 versus $4.62 a year earlier.

Management tone: Management's tone sharpened from Q1 to Q2. Q1 was framed as resilient markets and solid execution; Q2 was described with phrases like “broad-based strength” and “no one is slowing down at the moment.” Management was mostly direct on capacity drivers, lead times, and pricing, and candid that the Q2 margin beat was helped by IEEPA recoveries.

Management Guidance

For FY2026, management guides sales and revenues growth to mid-to-high teens, adjusted operating margin higher than the April expectation but near the bottom of the target range excluding IEEPA recoveries, tariff costs of ~$2.2 billion with no additional IEEPA recoveries in H2, MP&E free cash flow in the top half of the $6–15 billion range, capex of ~$3.5 billion, restructuring costs of ~$300–350 million, and an effective tax rate of ~23% excluding discrete items. Q3 tariff costs are guided to ~$600 million.

Trajectory

Revenue is accelerating: quarterly sales rose from $16,569M in Q2 2025 to $17,638M in Q3, $19,133M in Q4, then $17,415M in Q1 2026, and jumped to $20.5B in Q2 2026, up 24% y/y. Gross margin expanded 210 bps on a trailing basis, while operating and EBITDA margins were stable; the Q2 adjusted operating margin of 21.9% included $392M of IEEPA tariff recoveries. Power generation demand, record backlog, and supply constraints are driving the top line, while Resource Industries margin lags the rest.

The Model

The model projects FY+1 revenue of $76,000 million and EBITDA of $16,492 million (21.7% margin), rising to FY+2 revenue of $85,500 million and EBITDA of $19,922 million (23.3% margin). Near-term projections are anchored by record backlog and planned H2 throughput; FY+2 assumes continued power generation order conversion, capacity expansion, and modest margin expansion.

Projections are the median of 5 independent model runs. The model’s revenue sits 0.4% above analyst consensus.

For FY2026, management guides sales and revenues growth to mid-to-high teens, adjusted operating margin higher than the April expectation but near the bottom of the target range excluding IEEPA recoveries, tariff costs of ~$2.2 billion with no additional IEEPA recoveries in H2, MP&E free cash flow in the top half of the $6–15 billion range, capex of ~$3.5 billion, restructuring costs of ~$300–350 million, and an effective tax rate of ~23% excluding discrete items. Q3 tariff costs are guided to ~$600 million.

What Could Go Right — and Wrong

Looking Ahead

Over the next 12 months, the main watchpoints are Q3 and Q4 2026 results: Q3 tariff costs and strong sales growth across all segments, H2 capacity conversion with first 10-MW engine shipments in Q4 2026, Major Projects fleet loading in Q3, and a Q4 CI dealer inventory drawdown over $1B. Full-year 2026 targets include mid-to-high teens sales growth and free cash flow in the top half of the $6–15 billion range.

The Company

Caterpillar is the world’s leading manufacturer of construction and mining equipment, off-highway diesel and natural gas engines, industrial gas turbines, and diesel-electric locomotives. Its Power & Energy segment is the direct AI-infrastructure link: large gas reciprocating gensets, Solar Turbines industrial turbines including the PGM130, and diesel standby gensets supply prime and backup power to data centers. Management frames the company as providing the invisible layer of the tech stack: critical minerals, reliable power, and physical infrastructure.

The company operates a global manufacturing footprint across North America, South America, Europe, and Asia, including Arkansas, Brazil, China, Illinois, France, North Carolina, India, Italy, and the United Kingdom. In 2026 it repurposed a 250,000-square-foot facility in Wamego, Kansas in under 12 months to package and ship the PGM130 turbine, restarted a 10-MW medium-speed gas reciprocating engine platform, and is expanding large reciprocating engine capacity toward nearly 3x 2024 levels. It also acquired RPMGlobal and Skycatch to add mining software and AI spatial-data capabilities.

Business Segments

Competitive Landscape

The 10-K names a broad competitor set by segment: Cummins, Deutz, Rolls-Royce Power Systems, Siemens Energy, GE Vernova, Generac, and Baker Hughes in Power & Energy; CASE/CNH, Deere, Komatsu, Volvo CE and others in Construction; and Deere, Epiroc, Hitachi, Komatsu, Sandvik, Volvo CE in Resource Industries. Supply-chain intelligence flags capacity additions at GE Vernova, Cummins, Generac, and Baker Hughes. Caterpillar is currently hard to replace in large gas recips, but the competitive field is mobilizing.

Supply Chain

Caterpillar sits at the power-generation bottleneck of the AI buildout: suppliers feed its engine and turbine manufacturing, and power developers, hyperscalers, compression services, and construction dealers buy its equipment. At least one neighbor read names Caterpillar explicitly: Vertiv lists CAT in its bring-your-own-power partnership.
