How it's calculated
- CAGR (compound annual growth rate):
CAGR = (Last / First)^(1 / years) - 1 - EPS (Earnings Per Share / 1株当たり利益):
EPS = Net profit attributable to owners / Shares outstanding
Short periods from a fiscal-year change are skipped. A starting value of zero or below gives no rate.
Profitability
Profit per yen of sales and of assets, and the three DuPont factors that multiply to ROE (ROE, ROA, DuPont analysis).

How it's calculated
- ROE (Return on Equity):
ROE = Net profit attributable to owners / Equity - ROA (Return on Assets):
ROA = Net profit attributable to owners / Total assets - DuPont analysis:
ROE = (Net profit / Revenue) x (Revenue / Total assets) x (Total assets / Equity)
The ROE line is the company's filed figure, computed on average equity. The DuPont factors use year-end figures, so their product can differ slightly.
Cash
Cash from operations, cash spent on investment, and what was left (free cash flow, cash conversion).

How it's calculated
- Free cash flow (FCF):
FCF = Operating cash flow + Investing cash flow - FCF margin:
FCF margin = Free cash flow / Revenue - Cash conversion:
Cash conversion = Operating cash flow / Net profit attributable to owners - Cash / total assets:
Cash and cash equivalents at year end / Total assets
Investing cash flow is negative when the company invests, so FCF is operating cash flow minus what was invested. Filings give no consistent debt line, so cash is shown against total assets instead of as net cash.
Dividends
The dividend per share over time, the share of profit it took, its size against book value, and how many times earnings covered it (DOE, dividend cover, payout ratio).
5 consecutive fiscal years without a dividend cut, including 5 years of increases in a row. The count runs back from the latest year with a dividend figure and stops at a gap or a fiscal-year change.

Piotroski checklist
Comparing the fiscal year to December 2025 with the year before: 4 of the 9 checks that could be evaluated (9 in total) answered yes.
- Net profit is positive (ROA above zero)Yes
- Operating cash flow is positiveYes
- ROA higher than the year beforeNo
- Operating cash flow larger than net profitYes
- Liabilities / total assets lower than the year beforeNo
- Current ratio higher than the year beforeNo
- No increase in shares issuedYes
- Gross margin higher than the year beforeNo
- Asset turnover higher than the year beforeNo
How it's calculated
- Equity ratio:
Equity ratio = Equity / Total assets - Altman Z'' score:
Z'' = 6.56 x (Working capital / Total assets) + 3.26 x (Retained earnings / Total assets) + 6.72 x (Operating income / Total assets) + 1.05 x (Equity / Total liabilities) - Piotroski F-score:
F-score = number of the nine checks passed (shown as 'passed of evaluated')
Z'' is Altman's 1995 form for non-manufacturers and non-US companies, using book equity rather than the share price. Piotroski's debt check uses liabilities divided by total assets, because filings carry no consistent debt line. A check whose input is missing counts neither way.
Owners & people
Who holds the shares by category, the company-reported total shareholder return, and the workforce (shareholder composition, TSR, average salary).
Shareholding by owner category
- Foreign corporations etc.26.34%862 shareholders
- Government and local authorities22.05%1 shareholders

- Foreign individuals0.03%1,007 shareholders
Note: treasury shares are not a separate category here: filings count them inside individuals and others (個人その他).
TSR rows share one starting point: the fiscal year end five years before the latest report. The first row covers one year and the last covers five. 100% means the holding, dividends included, was worth what it cost; the company reports the figure.
