Renesas Electronics (6723.T) — 2024Q1 FY2024 Earnings Call Analysis

Bottom Called, Margins Falling, Share Lost

Automotive share dropped 600bps and management admits the fix takes five years.

Thesis: Renesas is a legacy auto-chip vendor bleeding 600bps of share to Infineon due to architectural errors in 2018. Management admits the product fix lags revenue by five years (2027). They are masking current weakness with inventory accounting changes (combining channel and in-house) and segment reclassifications. The "AI" narrative is explicitly denied by management (single digits). This is a value trap.

Verdict: AVOID — Conviction: MEDIUM

Catalyst: Q3 guidance. If the "sluggish" Japanese Tier-1 inventory doesn't clear, the flat revenue guide collapses into a write-down.

Key Risk: China localization of power discretes. 25% of revenue is China-located, and local sourcing is accelerating in power products.

The Tell: The inventory chart change. Management decided to display in-house and channel inventory combined "for the sake of visual representation" after years of separating them. You only combine buckets when one is overflowing.

Detected Patterns

Friction Level: HIGH_FRICTION — Structural vs. Cyclical. Bull sees a cycle bottom with margin resilience. Bear sees a 5-year structural share loss to Infineon and accounting obfuscation.
