Dear Investors,

Thank you for your attention and support to Yeong Guan Energy. Yeong Guan-KY (1589) announced its consolidated revenue of NT$ 849 million for August 2022. This represents an increase of 8.00% MoM and an increase of 13.63% YoY.  In terms of the shipment, we delivered 17,849 tons in August, an increase of 11.17% MoM and an increase of 8.45% YoY. In August, YGG¡¯s business operations were unhindered and produced good results in revenue and shipments. Our production lines strived to overcome the impact of high temperature weather, power outages and power cuts in various regions of mainland China to ensure full production capacity and continuous deliveries. It is estimated that in September, without the interference of summer heat warnings and power cuts, the shipment performance is expected to continue to maintain a high level.
