Caterpillar stock in focus as AI data center theme meets upcoming earnings

Caterpillar (CAT) is back on investors’ radar after recent analyst commentary highlighted its role in AI data center construction, with this AI driven demand story now intersecting with the company’s upcoming earnings report.

Caterpillar’s share price has been under pressure ahead of earnings, with a 30 day share price return that is down 17.81% and a 90 day share price return that is down 8.41%. However, the year to date share price return is 36.16% and the 1 year total shareholder return is 91.78%, indicating strong longer term momentum behind the recent pullback.

If the AI infrastructure build out theme interests you, this could be a useful moment to broaden your watchlist with a focused set of 55 AI infrastructure stocks.

The recent pullback has reset expectations just as the AI data center story gains attention for Caterpillar. The key question is whether that combination still leaves enough upside, after this run, to justify the valuation investors are paying today.

Most Popular Narrative: 16% Undervalued

Caterpillar’s last close at $814.81 sits below a narrative fair value of $970.37, which frames the current pullback against a higher long term earnings story.

Record backlog growth across all three primary segments, driven by strong global infrastructure demand (particularly in North America, Africa, and the Middle East), positions Caterpillar for above-trend sales growth in late 2025 and into 2026, supporting top-line revenue expansion.

Want to see what sits behind that backlog story? Analysts are incorporating expectations for firm revenue expansion, rising margins, and a richer earnings base. It may be helpful to explore which specific forecasts would need to materialize for this valuation to make sense.

Result: Fair Value of $970.37 (UNDERVALUED)

However, this Caterpillar narrative also depends on smooth execution in the face of potential tariff costs and possible pressure on pricing power that could weigh on margins.

Another View on Caterpillar’s Valuation

The earlier fair value narrative presents Caterpillar as 16% undervalued, but the market multiples tell a different story. At a P/E of 39.8x, Caterpillar trades richer than both its peer average of 31.7x and the US Machinery industry on 26.8x.

The fair ratio sits even higher at 52.1x. That indicates the market could either move closer to this higher ratio or pull the stock back toward peers if expectations cool. For you, the practical question is whether this valuation gap points to more room for optimism or a thinner margin of safety.
