Castem Co., Ltd. and Castem Global Group's Castem Vietnam held a completion ceremony for the newly established Vietnam factory in Quang Ninh Province, Northern Vietnam, in January 2026. This is the first time our group has expanded into Vietnam, and this factory will be our seventh overseas production base. After the planned second phase of construction, it is expected to become the largest production base in the group in the future. The factory will manufacture lost-wax precision casting parts used in semiconductors, precision machinery, and construction machinery. We chose Vietnam, where economic growth is anticipated, as a new production base for our main business of lost-wax precision casting. Currently, we are advancing prototype production and plan to start mass production by the end of May 2026. Once the second phase of construction is completed by the end of 2028, we will ultimately be able to produce one million units per month (with a product shipment weight of approximately 120 tons per month). On the day of the ceremony, about 100 participants, including business operators and local stakeholders, attended and toured the various processes such as mold making, casting, and processing. Although we are starting with a compact system in terms of equipment and personnel, we will continue to take on challenges and advance our business to a new dimension.
