One-line summary: Power Systems segment (large diesel/natural-gas gensets) is now data-center-led, with record ~29.5% EBITDA margin, backlog into 2028, and a $450M / ~20 GW capacity expansion — the second genset beneficiary of the AI data-center power bottleneck.
What it is
Cummins's Power Systems segment makes large reciprocating-engine gensets (diesel + natural gas) for backup and prime power. For ai-power-gap-to-genset-bridge-power, CMI is the second genset leg beneficiary alongside caterpillar — on-site bridge/backup power for AI data centers.
Why it matters to stock-market
Power Systems has become Cummins's margin and growth engine on data-center demand, with multi-year backlog visibility — a capacity-constrained beneficiary of the same AI power bottleneck. A liquid US tradeable on the genset leg the wiki's power cascade hadn't connected.
Key facts
- Power Systems Q1 2026 revenue +19% YoY to ~$2B, with a record ~29.5% EBITDA margin (≈39% of total-company EBITDA), driven by data-center backup + prime power. FY2025 Power Systems ~$1.9B (+11%), already data-center-led. From 2026-06-01-autoresearch-cat-cmi-datacenter-genset-bridge-power.
- Order backlog extends into 2028 (multi-year visibility). From 2026-06-01-autoresearch-cat-cmi-datacenter-genset-bridge-power.
- Raised 2026 revenue guidance to 8–11%; announced a $450M investment to add ~20 GW of capacity; long-term target $45–50B revenue by 2030, EBITDA margin >20%. From 2026-06-01-autoresearch-cat-cmi-datacenter-genset-bridge-power.
- Demand math: a typical 100 MW data center needs 120–200 MW of backup generation. From 2026-06-01-autoresearch-cat-cmi-datacenter-genset-bridge-power.
Strengths (from a thesis-input perspective)
- Record Power Systems margins + backlog into 2028 = earnings visibility.
- Data-center power is ~39% of company EBITDA — a material exposure, less diluted than the diversified-industrial caveat assumed.
- Capacity expansion ($450M / 20 GW) sized to a structural, not one-quarter, demand read.
Weaknesses (from a thesis-input perspective)
- Partly priced — trades ~22× forward vs. a ~14× 5-year average; much of the AI-power re-rate may be in the stock.
- Bridge-vs-structural: backup-power regulation could make genset demand durable, or grid/nuclear catch-up could fade it.
- Cyclical industrial (trucking/engine end-markets) outside Power Systems.
