Earnings Release Classification · 95% confidence The document is a 2025 annual performance forecast announcement by Hangzhou Medike Optoelectronics Technology Co., Ltd.

This type of document is typically classified as an Earnings Release (ER) because it announces key financial results or forecasts for a fiscal period but is not a comprehensive annual report (10-K) or interim report (IR). It is not a report publication announcement (RPA) because it contains substantive financial data and analysis, not just a notice of report availability. Therefore, the correct classification is Earnings Release (ER). FY 2025
