CAT · Q1 2026 Earnings

Q2 FY2025 tariff shock absorbed → Q3 FY2025 tariffs escalate, demand re-rates → Q4 FY2025 capacity becomes the binding constraint → Q1 FY2026 capacity expansion re-raised, FY guide moves to double digits

Three quarters ago the data center opportunity was framed as incremental; two quarters ago as supply-constrained; this quarter as the central driver of a re-underwritten 6–9% enterprise CAGR. From the call: "The target for power generation sales has increased to more than three times sales by 2030 from a 2024 baseline." Combined with the new "nearly three times 2024 levels" large reciprocating engine capacity commitment, management has now committed capital twice in twelve months to chase the same secular trend — and the 2030 enterprise CAGR target has moved from 5–7% to 6–9%. The signal is that the November 2025 investor day floor was set conservatively and management is comfortable raising again before that meeting's targets have had time to age.

Capacity expansion has shifted from "aligned with backlog visibility" to "stepped up to chase backlog growth that outran the prior plan." Management's own framing: "Since we first announced our initial capacity expansion plans in January of 2024, our large reciprocating engine backlog has grown by more than three and a half times." The original 2x capacity plan was sized for a backlog that has since grown 3.5x — so management is raising the capacity target by 50% (2x → ~3x) and now committing to incremental units as early as 2027 with heavy investment in 2027 and continued spend in 2028–2029. This is a multi-year capex commitment that, by the company's own admission, will create accelerated depreciation drag on near-term margins.

Tariff language has gone from "fluid and mitigable" through "structural baseline" to operational matter-of-factness — with a quiet reduction in the FY estimate. In Q2 FY2025 tariffs were "fluid"; in Q3 FY2025 the disclosure framework was being debated; in Q4 FY2025 it was reset to "absolute incremental"; this quarter management lowered the FY2026 tariff estimate to $2.2–2.4B from $2.6B, citing the Supreme Court IEEPA ruling and ramping mitigation actions in the back half. Q1 actual tariff cost came in at ~$600M (vs. ~$800M expected, due to a favorable adjustment to the computation of 2025 tariffs), with Q2 guided to ~$700M. Despite the FY tariff cut, the margin guide stays "near the bottom of range" — the unspoken admission is that accelerated depreciation from capacity additions and incremental investment spend are consuming the operating leverage that the lower tariff bill should otherwise have unlocked.

The dealer-inventory disclosure has been narrowed in a way that quietly insulates the bull case. Management announced this quarter: "We will now report changes in dealer inventories in total and for construction industries only, removing the total machines analysis." The rationale offered — that 70%+ of P&E and RI dealer inventory is backed by firm customer orders — is plausible. But the timing is conspicuous: the change comes after Q4 FY2025's RI print was flattered by dealer build while sales-to-users declined 7%. Removing the segment-level dealer inventory disclosure makes the same dynamic harder for investors to detect next time it occurs.

Confidence in geopolitical resilience has firmed without becoming dismissive. Last quarter management still hedged on macro; this quarter the language is more assertive: "We are closely monitoring the environment, and we are not forecasting material impact to our 2026 outlook at this time." The hedge remains — but it is now framed as monitoring, not contingency.
