## Asset intensity and goodwill

Ratios are derived from reported values. Goodwill is used only when separately reported, never inferred from combined intangible assets.

| Metric | Value | Sources |
| --- | ---: | ---: |
| Asset intensity (fixed assets ÷ revenue) | 40.0% | S100YHPR |
| Fixed assets ÷ total assets | 30.3% | S100YHPR |
| Goodwill ÷ parent equity | 0.2% | S100YHPR |

Goodwill over 4 years: 41 → 29 JPY; total investing cash flow: -5,169 JPY. This does not imply causation.

### Cash quality

Net cash = cash − interest-bearing debt. Net debt ratio = (interest-bearing debt − cash) ÷ positive operating cash flow. Omit when debt components are incomplete; other ratios are derived from reported figures.

| Metric | Value |
| --- | ---: |
| Cash ratio (cash ÷ total assets) | 16.4% |
| Cash ÷ revenue | 21.6% |
| Net cash (cash − interest-bearing debt) | ¥1.4B |
| Net debt ÷ operating cash flow | -1.01× |
| Cash conversion (operating CF ÷ operating income) | 77.3% |
| Cash vs. profit gap | -206 JPY mn (of net income -12.9%) |
| Shareholder returns / net income | — |
| Shareholder returns / FCF | — |
| Shareholder payments — dividends / net income | 18.9% |
| Shareholder payments — dividends / FCF | 54.7% |
| CapEx intensity (capex ÷ revenue) | 3.8% |
| Investing CF relative to operating CF | 54.7% |

## ROA and ROE

ROE is decomposed into net margin × asset turnover × financial leverage. Leverage can raise ROE, so the ratio alone does not assess a company's condition. Ending balances are used without a prior year; total equity approximates parent equity when unavailable.

| Period | Net margin | Asset turnover | ROA | Financial leverage | ROE | Sources |
| --- | ---: | ---: | ---: | ---: | ---: | ---: |
| 2022 | 5.7% | 0.97× | 5.6% | 1.38× | 7.7% | S100R56H |
| 2023 | 6.8% | 1.03× | 6.9% | 1.38× | 9.6% | S100TU6X |
