Ebara Corporation
Makes CMP polishing and plating equipment for semiconductor fabs.
On the record
Checkpoint: Ebara FY2026 Q2 earnings briefing, watch for order commentary on advanced-packaging CMP versus AMAT's Opta
The call
Ebara's fab-tool lock-in is intact and AI capex is filling its order book, while AMAT's new Opta platform is the one live challenge worth watching in HBM packaging.
Ebara builds machines that polish and coat computer chips inside semiconductor factories. It is hard to replace because factories spend 12 to 24 months testing new equipment before switching, Ebara is the only vendor offering a complete set of tools for an entire factory, and customers pay recurring fees for maintenance on machines already installed. Applied Materials is its main rival, and the real threat is not competition but a slowdown: if chip makers stop buying as many new tools before 2028, the record orders Ebara is getting right now from AI and advanced memory chip factories could dry up suddenly.
Why
01
AI pressure: None apparent. AI chip demand is the customer here: HBM and logic capex is filling Ebara's order book, not replacing its tools. Could AI do the core job? Unlikely.
02
Bigger players: Applied Materials (AMAT). AMAT shipped its Opta CMP platform for hybrid bonding and HBM in June 2026, aimed at the fastest-growing niche Ebara also serves. Could a giant copy it? Probably.
03
What protects it. Fabs requalify CMP tools on 12 to 24 month cycles, and Ebara is one of only two vendors covering the full CMP, plating, and vacuum stack.
What would change this call
Ebara's next 2-3 earnings calls show CMP/advanced-packaging order growth versus prior quarters. Slowing growth would suggest AMAT's Opta platform is capturing HBM/packaging share.
Ebara announces a competing advanced-packaging CMP platform within 2-4 quarters of AMAT's June 2026 Opta launch. A timely response would show Ebara defending its niche rather than ceding it to AMAT.
Memory/HBM customer order commentary in Ebara's FY2026-2027 briefings shows sustained versus reversing order levels. A sharp reversal would indicate AI capex plateau risk materializing earlier than 2028.

Key numbers
- FY2025 revenue: Y958.2B, fifth straight record year
- Q4 FY2025 CMP orders jumped to Y68.5B from Y33.1B in Q3
- Q1 FY2026 orders: Y324.9B, cited AI-driven logic/memory demand
Named risks
- AI/HBM-driven memory capex could plateau around 2028, reversing current record CMP order cycle.
- Applied Materials' Opta platform (launched 2026-06-25) could take share in fast-growing advanced-packaging CMP niche.
- Unresolved litigation after Supreme Court remanded Ebara Environmental Plant damages case, 2026-07-07.
- FY2026 guidance revised downward in May 2026 due to logistics and geopolitical tensions.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Applied Materials | contesting | AMAT launched Opta CMP platform for HBM/hybrid bonding, 2026-06-25, targeting Ebara's growth niche |
| Applied Materials | losing to | AMAT held ~73.8% CMP polisher share vs Ebara's ~20.6% per 2005-06-15 third-party data |
| Applied Materials | gaining on | Analyst Robert Castellano argued 2026-04-11 that current CMP share data favors Ebara over AMAT's own claims |
Questions people ask
- Is Ebara Corporation profitable in 2026?
- Yes. Ebara posted FY2025 (ended Dec 31, 2025) operating profit of ¥113.8 billion and net profit attributable to owners of ¥76.6 billion on revenue of ¥958.2 billion, marking its fifth consecutive record year. Q1 FY2026 orders rose to ¥324.9 billion, extending the growth trend.
- Could AI replace Ebara Corporation's products?
- No. Ebara makes physical CMP polishers, plating tools and vacuum pumps used inside chip fabs, which software cannot substitute. Instead AI is fueling demand: Q4 FY2025 CMP orders jumped to ¥68.5 billion from ¥33.1 billion in Q3, driven by AI logic and HBM memory capex, per its 2026-02-13 earnings script.
- Who is Ebara Corporation's biggest competitor?
- Applied Materials (AMAT) is Ebara's main rival in semiconductor CMP, forming a long-standing duopoly. AMAT launched a new 'Opta' CMP platform for hybrid bonding and HBM/3D stacking on June 25, 2026, directly targeting Ebara's fastest-growing advanced-packaging niche.
- Who owns Ebara Corporation?
- Ebara is an independent publicly traded company, not owned by a parent, listed on the Tokyo Stock Exchange Prime Market under ticker 6361 and included in the Nikkei 225. Its market capitalization was approximately ¥2.62 trillion as of July 24, 2026.
- Is Ebara Corporation facing layoffs or cost cuts?
- No layoff signals appear in current disclosures. Group headcount grew from 20,510 to 21,148 between December 2024 and December 2025 (+3.1%), and Ebara instead divested non-core Swing Corporation for ¥91.2 billion in April 2026 to sharpen its portfolio.
- How exposed is Ebara Corporation to a semiconductor downturn?
- Management itself flagged risk that AI/HBM-driven memory capex could plateau around 2028, and Q3 FY2025 CMP order softness was tied to memory customer order delays, per Ebara's 2025-11-13 Q&A, meaning current record orders partly reflect inventory build-ahead.
