Recurring revenue,
across Japan.
We narrowed 3,826 Japanese stocks to 389 profitable, high-margin companies with sound finances. AI read their filing excerpts and judged 151 as supported. Here are 12 examples checked against the source text.
01 / Input
The companies we wanted to find.
“Japanese companies with an operating recurring-revenue mechanism in a principal business, such as subscriptions or renewable maintenance contracts, that are profitable, highly profitable in their operations, and financially sound.”
For this example, a separate AI prepared the conditions; Katana ran the financial screen and filing judgments.
02 / Conditions
The conditions we applied across Japan.
Qualitative
AI reads each annual report and judges support and counterevidence.
- Does a principal business currently earn recurring revenue from existing contracts or its customer base through subscriptions, renewable maintenance or management contracts, or ongoing usage fees?
Repeat product purchases or future plans alone do not qualify. This condition does not require recurring revenue to exceed half of total company sales.
