Partly disclosed — a gap remains · New Medium-Term Management Plan · Vision 2030 and Cash Allocation
The question this leaves open
Investor question: What utilization and margins underpin the ¥27bn semiconductor-equipment target? IR preparation: bridge backlog, capacity, spend, margins and ROIC.
Our analysis, not a company statement
Balance sheet and capital-policy indicators
A source-backed first-pass capital-efficiency, balance-sheet and governance reading, separate from the accountability score.
Cash use and returns
Okamoto prioritizes semiconductor grinders and polishers and previously framed six-year investment of ¥18bn; the new plan targets ¥27bn of semiconductor-equipment sales by FY2028.
Capital structure
Management raises the payout target to 45%, but the selected plan provides limited liquidity and leverage guardrails.
Governance of capital decisions
The company accelerated its Vision 2030 operating targets to FY2028, yet project-level ROIC and hurdle rates remain undisclosed.
Preliminary and not scored: a selected-source reading, reviewed 30 September 2026. Surplus cash, leases, maturities, project ROIC, cost of capital, committed spend and peer comparability are not fully assessed; none enters the accountability score. Figures are the company’s own reported numbers; a large cash balance is not called excess without a defensible operating reserve and investment plan. Every company with a balance-sheet reading →
