Caterpillar’s Record Backlog Still Leaves an AI Power Concentration Risk
Caterpillar’s second-quarter sales, cash flow and power-generation growth were exceptional, supported by data-center demand. The same strength creates concentration risk if customer capital budgets slow or competitors capture more distributed-power spending.
Caterpillar’s data-center opportunity is no longer a side story. Second-quarter sales and revenue reached $20.5 billion, up 24% from a year earlier, while adjusted earnings per share were $8.17 and operating cash flow was $4.4 billion.
Power generation was the standout. Retail sales in the category increased 72%, and Power & Energy operating profit reached $2.027 billion, up 30%. Caterpillar also described backlog as strong, giving the company visibility that extends beyond one quarter.
The numbers explain why investors have attached a premium to the power business. Data centers need reliable electricity, and Caterpillar can sell engines, generator sets and related services into projects that cannot wait for grid expansion. Demand can continue even when traditional construction markets slow.
That strength also creates a new form of concentration. If a large share of incremental growth comes from data-center power, Caterpillar becomes more exposed to the capital budgets and project schedules of a relatively small group of infrastructure buyers. Broadcom’s CEO has separately warned that customer capital could become the constraint on AI expansion, a risk that can travel through the supply chain.
Competition matters as well. Fuel cells, turbines, linear generators and grid solutions can address parts of the same problem. Caterpillar does not need to win every project, but high expectations leave less room for slower order growth or pricing pressure.
The company enters this period with record operating evidence rather than a speculative promise. Strong cash generation, backlog and power growth provide a substantial cushion. The risk is that investors extrapolate a 72% category growth rate too far into the future.
The next proof points are order conversion, backlog quality, margins and customer diversity within Power & Energy. Caterpillar can remain an important supplier to AI infrastructure even if growth normalizes. What would challenge the stock is a simultaneous slowdown in data-center capital spending and compression of the premium investors assign to that growth.
