Missed AI’s “Act 1”? Act 2 Could Be 14x Bigger. Most investors think they missed the AI boat because they didn’t buy Nvidia in 2005. But according to our analysts, we’re only at the end of “Act 1″\u2014the R&D phase. “Act 2” is the global rollout. Continue \u00bb<\/a> <\/p>\n How do I know this? Well, just look at the company’s most recent quarterly results. <\/p>\n In the second quarter, Caterpillar’s total revenue grew an impressive 24% over the same quarter in 2025. And earnings per share soared 73% from a year ago. <\/p>\n Power equipment sales are driving revenue growth <\/p>\n But you only need to dig a little deeper to uncover which segment is really exploding at the company: power generation. Total retail sales for the power and energy segment rose 33% in the quarter. And what drove that? Retail sales of power generation equipment, which climbed an incredible 72%. <\/p>\n In the earnings call after the Q2 results were released on Aug. 4, CEO Joseph Creed said the increase was due to “very strong demand for large gen[erator] sets and turbines used in data center applications.” <\/p>\n AI data centers have a nearly insatiable thirst for power, so sales of power-supplying equipment are going gangbusters. In 2025, data centers consumed about 4.9% of the U.S. electricity supply. In some states, that was more than 10%; in data center-heavy Virginia, it’s more than one-quarter. Electricity consumption by U.S. data centers is projected to more than double by 2030. And from there, who knows? <\/p>\n Better still, customers for Caterpillar’s power and energy equipment are now placing orders through 2030. As a result, the company’s backlog, now at a record $72 billion, has expanded 92% over the past year. <\/p>\n So, a large portion of Caterpillar’s revenue growth right now is driven by data center construction and power needs. And that looks to increase in the coming months and years. Caterpillar calls its power and energy its “Largest and Fastest Growing Segment.” <\/p>\n Caterpillar will report its third-quarter earnings on Oct. 29. Wall Street expects revenue growth of 17% over the same quarter last year and earnings of $7.03 per share, up 42% from a year ago. I wouldn’t be surprised if the company beats those estimates. <\/p>\n For investors who believe, as I do, that the AI spending juggernaut will continue for years to come, investing in Caterpillar is a good way to profit from it while diversifying a bit from the core AI stocks.<\/a> <\/p>\n Should you buy stock in Caterpillar right now? <\/p>\n Before you buy stock in Caterpillar, consider this: <\/p>\n The Motley Fool Stock Advisor analyst team just identified what they believe are the 10 best stocks<\/a> for investors to buy now\u2026 and Caterpillar wasn’t one of them.
