Powell Industries (POWL)

Electrical switchgear / power-distribution equipment — long-lead data-center/industrial gear

AI exposure 30% — derived from reported segment revenue, not asserted.

Where it sits

Physical Infrastructure → Power & Electrical Equipment · figures rebased to FQ3 FY2026, reported 2026-08-03

Custom switchgear, bus duct, control systems for oil&gas/petrochemical (largest) leads 2 businesses in this sub-tier that together are 100% of revenue, so Power & Electrical Equipment is effectively the whole company rather than one leg of it.

Reported segments

• Electrical power equipment (by end-market) — 100% of revenue

Powell Industries ($311.7M FQ3 FY2026, +9% YoY) — custom electrical power equipment (switchgear, bus duct, control). Historically oil&gas/petrochemical (~55%) but rapidly diversifying to utility/DATA CENTER/industrial (~45%, fastest-growing). Primary B2 Power & Electrical Equipment. Data-center power equipment is the new AI growth vector. Competes ETN/SIEGY in switchgear; supplies data centers/utilities.

How the 30% is built

• Electrical power equipment (by end-market) — 100% of revenue × 30% AI-driven (estimate). Powell now quantifies data centers in bookings (>$400M of the record $934M fiscal Q3 2026 orders, alongside ~$75M petrochemical and ~$60M LNG awards) but does not disclose a data-center share of REVENUE; with a $2.4B backlog covering ~7.7 quarters, the recognized-revenue mix still lags the order mix, so 30% is held…

Investment read

Moat. A custom engineer-to-order switchgear specialist with qualified-vendor standing across utility, petrochemical and now data-center work — a real but narrow capability advantage against far larger rivals (Eaton, Siemens, Schneider, ABB). The record $2.4B backlog (+69% YoY, ~7.7 quarters of sales) is a position, not the moat.

Bottleneck / pricing power. Pricing power is bookings-side and holding rather than expanding: gross margin was flat at 30.6% in fiscal Q3 2026 while orders hit a record $934M at 3.0x book-to-bill. The binding constraint has flipped from demand to Powell's own delivery capacity — hence the new ~300,000 sq ft leased facility on top of the Jacintoport expansion.

Role in the AI stack. The switchgear/power-distribution bottleneck supplier.
