Renesas Electronics (RNECY)

Embedded MCUs + analog/power (Renesas) — automotive + industrial embedded

AI exposure 10% — derived from reported segment revenue, not asserted.

Where it sits

Silicon Layer → Analog, Logic & Mixed-Signal ICs · figures rebased to Q2 2026, reported 2026-07-31

MCUs + analog + power for industrial, data-center/infrastructure (incl. Altium, server power) leads 2 businesses in this sub-tier that together are 52% of revenue and the largest business on the map, which is what Analog, Logic & Mixed-Signal ICs holds. The remaining 48% (Auto MCUs, SoCs, analog (ADAS, body, powertrain)) is deliberately off-map.

Reported segments

• Industrial / Infrastructure / IoT — 53.4% of revenue
• Automotive — 46.2% of revenue

Renesas (JPY 405.3B Q2 2026, +24.8% YoY and +8.8% sequential, at a 58.1% gross margin and 32.7% operating margin). The segments have swapped: Industrial/Infrastructure/IoT 53.4% (JPY 216.3B, +40.0% YoY on data-centre and AI demand, 31.9% operating margin) = primary B1 Analog, Logic & Mixed-Signal ICs, against Automotive 46.2% (JPY 187.1B, +15.9%) — a year ago automotive was the larger half. The AI-linked segment is now both bigger and growing nearly three times faster.

How the 10% is built

• Industrial / Infrastructure / IoT — 53.4% of revenue × 18% AI-driven (disclosed). Data-centre power management and timing devices are the named driver of 40% growth, inside a segment that also serves broad industrial and IoT markets
• Automotive — 46.2% of revenue × 0% AI-driven (disclosed). Vehicle microcontrollers and SoCs — no AI-infrastructure content

Investment read

Moat. Top-tier automotive MCU franchise inside a 5-6 player oligopoly — safety-critical designs qualified into a platform for a decade create real switching costs — plus analog/power breadth from Dialog/Intersil now feeding data-center and NPU power. Auto-cycle exposed, but the stickiness is structural, not cyclical.

Bottleneck / pricing power. Real pricing power, now disclosed rather than asserted: 58.1% non-GAAP gross margin and 32.7% operating margin in Q2 2026, 370bps above guide. The inventory correction referenced in the old read is over — three straight quarters of accelerating growth, Q3 guided to Y430B (+28.7% YoY).

Role in the AI stack. The automotive/industrial embedded MCU + power supplier.
