Dear Investors,

Thank you for your attention and support to Yeong Guan Energy. Yeong Guan-KY (1589) announced its consolidated revenue of NT$ 528 million for January 2023. This represents a decrease of -44.6% MoM and a decrease of -21.5% YoY.  In terms of the shipment, we delivered 9,753 tons in January, a decrease of -49.3% MoM and a decrease of -32.1% YoY. In January, it coincides with the New Year's Day holiday and the Lunar New Year holiday, and the number of working days in the whole month is less than half a month, so the output and shipments are low. Looking forward to February, YGG will put forth their full effort to meet the set goals and strive for brilliant results.
