Mitsubishi Electric (MIELY)

Industrial automation + power conglomerate (Mitsubishi Electric) — factory automation + power

AI exposure 5% — derived from reported segment revenue, not asserted.

Where it sits

Physical Infrastructure → Industrial & Factory Automation · figures rebased to Q1 FY3/27, reported 2026-07-31

Factory automation is Mitsubishi Electric's largest single AI-relevant business at 16% of revenue, driven by AI-semiconductor capex, and its three core rivalries — Rockwell, Emerson and Siemens — are all contested there. It had been placed in Power & Electrical Equipment on the combined 17% of Energy Systems and Public Utility, but those are two separate businesses inside the Infrastructure segment and rule 2 follows the largest single business. The company's own segment note already flagged this for revisit. Power and UPS for overseas data centres stays a secondary tag.

Also tagged: secondary in Physical Infrastructure → Power & Electrical Equipment; emerging in Software Stack → Data & Infrastructure Software; emerging in Silicon Layer → Analog, Logic & Mixed-Signal ICs; emerging in Frontier & Emerging Bets → Defense & Government AI.

Reported segments

• Industry & Mobility — 28% of revenue
• Life — 25% of revenue

Mitsubishi Electric (¥5,521B/~$37B FY2025). Six segments. Industry & Mobility ~28% (Factory Automation = PRIMARY B2 Industrial & Factory Automation, driven by AI-semiconductor capex; automotive off-map). Life ~25% (HVAC/elevators off-map). Infrastructure ~22% (power T&D + UPS for data centers = B2 Power; Defense & Space = B7). Business Platform ~10% (IT services = B5). Semiconductor & Device ~8% (power modules + optical devices = B1). Current primary B2 Power. Consider B2 Industrial Automation primary (FA is largest AI-relevant). FLAG.

How the 5% is built

• Industry & Mobility — 28% of revenue × 3% AI-driven (estimate). Management attributes the FY2027 guidance raise to 'growing demand related to AI and semiconductors' in factory automation — but that is an attribution of incremental growth, not a revenue figure, and the segment also carries a large off-map automotive equipment business; left unchanged rather than moved on a…
• Life — 25% of revenue × 0% AI-driven (estimate). Home appliances and building systems have no AI/data-center linkage
• Infrastructure — 22% of revenue × 10% AI-driven (estimate). Unchanged estimate — power transmission/distribution equipment and data-center UPS; the only quantification remains the ~2-years-of-annual-UPS-sales backlog disclosed back in Q3 FY2026, which Q1 FY2027 did not update
• Business Platform — 10% of revenue × 12% AI-driven (estimate). Unchanged estimate — IT and communication systems include some AI/data-solutions work, still a small business
• Semiconductor & Device — 8% of revenue × 15% AI-driven (estimate). Unchanged estimate — power modules and optical devices serve server power delivery as one of several end markets alongside automotive and industrial
• Others — 7% of revenue × 0% AI-driven (estimate). No direct AI linkage

Investment read

Moat. Diversified industrial (factory automation, power devices, building systems) at scale; FA + power exposure to the buildout, conglomerate-diluted.

Bottleneck / pricing power. Moderate pricing power (FA installed base + power breadth); a conglomerate where the AI-relevant pieces (FA, power semis) are minority slices.

Role in the AI stack. The factory-automation + power conglomerate — diluted AI exposure.
