Not scored. 1 action has been reviewed; a score out of 100 is published once 3 or more are. The ratings:

Semiconductor power-supply outlook and forecast revisionspecific promise 4/5 · steps traceable 3/5 · economics explained 2/5 · report-back not yet due

Each action is read against the company’s own filings on four checks: was the promise specific, can the steps be traced, were the economics explained, and did it report back against the target. This records the status of selected actions, not an assessment of the company as a whole. How this is scored →

The question this leaves open

Investor question: What working capital and incremental investment support the recovery? IR preparation: reconcile original and revised forecasts, final actuals, inventory, orders and investment returns.

Our analysis, not a company statement

Was the promise specific?4/5Annual forecasts are quantified and dated, but investment and return commitments are limited.
Can the steps be traced?3/5Original and revised forecasts and interim actuals can be traced; final outcome is unverified.
Were the economics explained?2/5Demand and product rationale is described; quantified project capital and return thresholds are not verified in these sources.
Did it report back against the target?not yet dueAugust 2026 year-end has passed; final annual result remains unverified, so this check is pending.

Balance sheet and capital-policy indicatorsreviewed 1 October 2026

A source-backed first-pass capital-efficiency, balance-sheet and governance reading, separate from the accountability score.

¥13.6bnFY2026/8 sales forecastRevised forecast, not final actual.10 July 2026 · FY2026/8 third-quarter results
¥2.5bnFY2026/8 operating-profit forecastRevised forecast.10 July 2026 · FY2026/8 third-quarter results

Cash use and returns

The July update increases the annual sales, profit and dividend outlook as semiconductor equipment orders improve. Selected results do not establish project-level return on incremental development or capacity.

Capital structure

May 2026 cash and deposits were ¥8.767bn and equity ratio 52.1%; these are reported balances, not evidence of excess cash or a target leverage policy.

Governance of capital decisions

The October original and July revised forecasts make changes observable; quantified investment hurdles and allocation decision gates are not verified in these selected results.

Preliminary and not scored: a selected-source reading, reviewed 1 October 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 →
