Future Outlook

Parataxis Korea anticipates becoming cash-flow positive in fiscal year 2026, driven by its vertically-integrated BTC yield platform, which is expected to generate approximately 60% EBITDA margins.

Korea continues to be one of the most compelling markets globally for Bitcoin adoption, and we're just getting started."

Industry Context
