Resonac Holdings (4004.T) — 2025Q4 FY2025 Earnings Call Analysis

Segment Margin Hits Target, Group EPS Sits at 32% of Goal

They just introduced an adjusted EPS metric because the real one printed ¥160 against a ¥500 target.

Thesis: The semi segment is genuinely executing: 14% revenue growth, record ¥108.4B core profit, EBITDA margin clearing 30% on reported numbers not adjusted ones. But the group has zero pricing power (-¥30.7B price line), ROIC at 6.2% versus 10% target, and four of five segments guided down for FY2026. The AI back-end materials CAGR claim (20-50%) has no order book, no backlog, no book-to-bill behind it. The semi story is real but you are buying a conglomerate where the other 60% is shrinking while management sells assets to paper over ¥62.5B in recurring 'one-time' impairments.

Verdict: HOLD — Conviction: MEDIUM

Catalyst: Krasus Chemical partial spinoff closing in 2026 and further non-core exits, which management says will 'put an end to large impairments' and let the market revalue the semi segment on standalone numbers. Could compress the conglomerate discount if semi margins hold at 30%+.

Key Risk: FY2026 semi segment guidance could come in below plan if AI back-end demand decelerates. The 20-50% CAGR claim has zero order data backing it, and a guidance cut in the one segment holding the thesis would crush the story.

The Tell: CFO Somemiya: '非経常項目を除くベースの調整後EPSも併せて開示' with the stated purpose of making core earnings 'easier to understand' against the ¥500 target. They created a new metric because ¥160 versus ¥500 was indefensible. When management introduces an adjusted number unprompted, the raw number is the problem.

Detected Patterns

AI Label Without Substance: The 20-50% CAGR for AI back-end materials is described as '期待され' (expected). No backlog, no book-to-bill, no customer concentration. The number is a market projection the CEO repeated without attaching order book evidence.
Say/Do Gap: EPS target ¥500, actual ¥160. ROIC target 10%, actual 6.2%. Three straight years of large impairments labeled non-recurring. CFO introduces adjusted EPS to bridge the gap between target and reality.
Zero Pricing Power Despite Constraints: Group price line shows -¥30.7B drag from graphite electrode pricing and naphtha declines. Even the semi segment's volume-driven +¥18.3B profit was partially offset by cost inflation. Materials suppliers to fabs and OSATs cannot raise ASP.
Margin Expansion Engine: Semi segment EBITDA margin expanded from 25.9% to 30.2%, hitting the 30% target on reported numbers. Core operating profit of ¥108.4B is a record. This is the one genuinely clean data point in the call.
Capital Conviction: CEO committed more than half of operating cash flow to growth investment, concentrated in semi materials. ¥203.4B EBITDA against ¥46.7B IFRS operating profit gives balance sheet capacity to fund the transition.
Mix Shift Spin: EBITDA margin of 15.1% reported versus 18.4% excluding Krasus. Management presents the ex-Krasus figure as the real number while guiding Krasus for a spinoff that hasn't closed. The margin improvement comes from excluding what they are about to sell.

Friction Level: MODERATE_FRICTION — Both sides agree semi segment margin expansion (25.9% to 30.2%) is real execution. Bull sees a re-rating catalyst as the conglomerate discount unwinds. Bear sees zero pricing power (-¥30.7B price line), a Say/Do Gap on EPS, and an AI CAGR claim with no order book behind it. Disagreement is whether segment-level strength can carry a group where four of five segments decline in FY2026.
