SG's shares surged more than 22% in early trading after the company announced it would exclusively supply asphalt to the SK Hynix advanced semiconductor cluster construction site in Yongin. The news has attracted investor interest, particularly as it highlights SG's commitment to using eco-friendly asphalt at Samsung Electronics' Pyeongtaek Campus P5.


As of 9:16 a.m. on July 8, SG's stock was trading at 1,846 won, up 337 won (22.33%) from the previous trading day, according to the Korea Exchange.


SG confirmed that it would be the sole supplier of asphalt for the SK Hynix Yongin advanced semiconductor cluster project, which is a national strategic initiative involving an investment of approximately 122 trillion won. This project is expected to generate hundreds of trillions of won in production effects, making it the largest semiconductor production base in the country. As large-scale infrastructure construction begins, ensuring a stable supply of high-quality construction materials is seen as a key challenge.


The company stated that this supply deal allows it to participate in the core infrastructure construction from the early stages of SK Hynix's massive semiconductor production facility.


Additionally, SG is working to implement its eco-friendly product, 'Eco Steel Asphalt,' at Samsung Electronics' P5 semiconductor plant. From June 15 to 17, Samsung C&T conducted test paving with Eco Steel Asphalt at the P5 site, with oversight from the supervisory team and SG's technical and sales representatives.


SG plans to expand its supply of eco-friendly, high-value-added products for major domestic semiconductor and advanced industry infrastructure projects, leveraging its exclusive supply record for the SK Hynix Yongin cluster and its initiatives at Samsung Electronics' P5.


An SG representative stated, "The exclusive supply to the SK Hynix Yongin advanced semiconductor cluster is a significant reference that demonstrates SG's quality competitiveness and stable supply capabilities. With the confirmation of economic viability and quality competitiveness through the Samsung Electronics P5 test paving, we aim to enhance our market competitiveness by expanding our supply to major domestic semiconductor and advanced industry infrastructure projects."
