Lubin scoring methodology

Premium Water Holdings,Inc. (2588.T)'s score is calculated automatically from 10 objective financial criteria, with no human intervention or opinion. Each criterion is validated (YES / PARTIAL / NO) based on thresholds drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran). The final score is the sum of validations.

The thresholds come from the financial literature, not from our preferences: see the valuation work of Aswath Damodaran (NYU Stern) and the SEC investor education resources (investor.gov).

The 10 quantitative criteria analyzed

1. Profitable: net margin > 5%
2. Growing revenue: revenue growing > 10%/year over 5 years
3. Growing earnings per share: FCF per share adjusted for stock-based compensation, > 10%/year over 5 years
4. Share count under control: stable or declining (net buybacks = value creation for shareholders)
5. Growing revenue per employee: revenue and revenue per employee both grow ≥ 10%/year over 5 years; partial when only one growth driver reaches its tier (fallback: free cash flow margin > 10% when employee history is unavailable)
6. Expanding margins: operating margin widens over 5 years (operating leverage)
7. Return on invested capital: Cash ROCE > 15% per year
8. Debt under control: net debt repayable in less than 3 years of free cash flow
9. Earnings converted to cash: free cash flow exceeds accounting net income
10. Net collection period: short or negative cash conversion cycle
