Notice of Termination of Monthly KPI Flash Report Disclosure for Contracted Processing Services Business

Change in IR Policy and Background

CellSource has decided to terminate the disclosure of monthly KPI flash reports for the contracted processing services business. To enhance transparency and reliability for investors, the company determined that quarterly-based disclosures are more appropriate for monitoring the progress of its business strategy. The monthly KPI flash report will end with the October 2026 monthly report, and no reports will be disclosed thereafter. Going forward, the company will provide information useful for investment decisions through quarterly financial presentation materials and financial summaries.
