Dogs
Petrochemicals (Crasus Chemical)
By end-2025 Resonac (formerly Showa Denko group) began spinning off petrochemical unit Crasus Chemical as a Dogs portfolio: olefins/derivatives with single-digit CAGR, EBITDA margins near 4–6% in 2024 and ROIC under 5%, hit by cyclical demand and >€40/tonne compliance costs.
Secondary Battery Packaging Materials
Secondary Battery Packaging Materials: despite global EV battery pack demand rising 28% year-on-year to 1.8 TWh in 2024, price pressure left Resonac with under 3% share in the segment and negative 2024 EBITDA margins (~-5%), so the unit is classed as a Dog.
After missing 2024 profitability targets, Resonac moved in 2025 to transfer or liquidate portions of the business, cutting related headcount by ~120 and recognizing a ¥6.2 billion impairment in Q1 2025.
Management calls it low-growth, low-share and prioritized exit to streamline structure; expected cash savings are ¥2.5–3.0 billion annually post-disposal, improving corporate ROIC in 2026.
Legacy Food Packaging Materials
Legacy Food Packaging Materials operates in a highly commoditized market with ~1% CAGR and low margin pressure; dented EBITDA margins were about 3–5% in FY2024, well below Showa Denko Group averages. Resonac (successor to Showa Denko’s separations) marked it non-core, citing ROIC near single digits versus group target ~12%. As part of the 2025 portfolio reform, these assets have been slated for divestiture or already transferred, freeing roughly JPY 15–30 bn in tied capital.
Standard Grade Graphite Electrodes
Standard Grade Graphite Electrodes suffer low market share and margins versus UHP cash cows; by 2024 Resonac (formerly Showa Denko K.K.) reported standard grades generating near-break-even EBITDA margins under 5% while UHP exceeded 20%.
Facing fierce competition from low-cost regional producers in China and Southeast Asia, Resonac cut standard-grade volumes ~40% from 2019–2023 to stop resource drain and refocus on high-performance lines.
- Low margins: EBITDA <5% (standards)

- Volume cut ~40% (2019–2023)
- Strategy: exit/limit standards to protect cash
Non-Core Inorganic Materials
Certain legacy inorganic chemical lines at Showa Denko K.K. have moved into the Dog quadrant due to stagnant demand and competition from specialized rivals; sales for these non-core products fell about 18% from 2021–2024, representing roughly JPY 24 billion of revenue in FY2024.
Resonac (formerly Showa Denko) is phasing out these items to lift ROIC and simplify the portfolio; management targets a 250–300 bps ROIC improvement by 2026 via divestment or shutdown of low-margin lines.
- Sales decline: −18% (2021–2024), ≈ JPY 24bn in FY2024
- Impact: Non-core share < 6% of total revenue
- ROIC goal: +250–300 bps by 2026
- Action: systematic phase-out, divestment, line shutdowns
Resonac to cut losses: spin-offs, exits to free JPY15–30bn and lift ROIC 250–300bps
By end-2025 Resonac (ex-Showa Denko) classed several low-growth, low-share units as Dogs: petrochemicals (EBITDA 4–6% 2024, ROIC <5%, €40+/t compliance), battery-pack materials (share <3%, EBITDA −5% 2024), standard graphite (EBITDA <5%, volumes −40% 2019–23), legacy inorganics (sales −18% 2021–24, JPY24bn); planned exits target JPY15–30bn capital release and +250–300bps ROIC by 2026.
| Unit | 2024 EBITDA | 2024 sales/size | Key action |
|---|---|---|---|
| Petrochemicals | 4–6% | — | Spin-off/divest |
| Battery pack mats | −5% | Share <3% | Exit/transfer |
| Std graphite | <5% | Volumes −40% | Limit/exit |
| Inorganics | Low | JPY24bn | Phase-out |
Question Marks
Power Semiconductor Materials (Gallium Nitride)
GaN (gallium nitride) power-materials for Showa Denko’s Resonac are a Question Mark: global GaN power-device revenue hit about $420m in 2024 (6% CAGR since 2020), but Resonac’s market share remains single-digit versus SiC leaders; adoption is early in fast-charging and 5G/RF telecoms.
GaN can become a Star if Resonac scales: expect >30% demand CAGR in fast chargers and base stations to 2028, but reaching competitive cost/performance needs multi-year R&D and capex—estimated ¥10–30bn investment—to match incumbents.
Carbon Recycling Technologies
Resonac (Showa Denko spin-off) invests in mineralization and CO2-to-chemicals tech to make raw materials from captured CO2; pilot CAPEX exceeded ¥8.5bn in 2024 and R&D spend rose 42% YoY to ¥3.1bn.
These are growing markets—global CCU (carbon capture and utilization) demand forecast ~40 Mt CO2/yr by 2030—but Resonac holds near-zero market share and faces high unit costs today.
