Caterpillar has become a major beneficiary of AI infrastructure buildout, with its Power Generation segment growing 41% in Q1 2026 on data center demand for turbines and engines. While the company's record backlog and strong earnings support near-term momentum, the stock's forward P/E of 41x and tariff exposure of $1.30 to $1.50 billion(約2400億円) have led analysts to rate it a hold despite 169% gains over the past year.

Caterpillar's Q1 2026 earnings beat consensus, with revenue of $17.41 billion(約2.8兆円) up 22.22% year over year and Power Generation revenue jumping 41% to $2.82 billion(約4500億円) on data center demand. The stock is now trading above $1,038 after climbing 74.34% year to date.
Why it matters
The company is benefiting from a record backlog and what analysts project could be roughly 25% annual growth in data center equipment for the next four to five years, driven by electrical infrastructure demand for large engines and turbines. However, the stock trades at a forward P/E of 41x, well above its historical range, and faces tariff headwinds of $1.30 to $1.50 billion(約2400億円) for the full year.
What to watch
Analysts see upside to $1,113.73 if the AI infrastructure cycle holds, but downside risk to $842.92 if Power Generation growth falls below 20% or if tariff costs persist. The Street's consensus target of $949.68 sits below the current price.
