[Asia Economy Reporter Hyungsoo Park] YesTY is showing strong performance. The expectation surrounding its collaboration with SK Group on the silicon carbide (SiC) power semiconductor business appears to be influencing its stock price.
As of 11:18 AM on the 3rd, YesTY is trading at 14,850 KRW, up 10.41% from the previous day.
On the same day, YesTY announced that it will additionally acquire 26,666 shares of YesPowerTechnics, a related company engaged in the design, development, and production of SiC power semiconductors, for approximately 3 billion KRW. After acquiring the shares, YesTY’s stake in YesPowerTechnics will increase to 34.2%. The scheduled date for the share acquisition is the 5th.
YesTY explained the purpose of the share acquisition as "expanding the stake in YesPowerTechnics and securing synergy for the unlimited growth potential of the SiC power semiconductor business."
Previously, SK invested 26.8 billion KRW in YesPowerTechnics to enter the SiC power semiconductor field, acquiring a 33.6% stake. It is known as the only domestic company that has established a production system for SiC power semiconductors, including a high-temperature process production line. The goal is to secure a leading position in the future automotive materials market by investing in silicon carbide power semiconductors, which are core components for electric vehicles and hydrogen vehicles.
SiC semiconductors are made from silicon carbide wafers. They have better heat resistance characteristics compared to conventional silicon semiconductors. They are used in fields requiring rapid data processing in a short time, with electric vehicles, hydrogen vehicles, and 5th generation mobile communications (5G) being representative examples. Power semiconductors are essential semiconductors that control the direction of current and manage power conversion.
YesPowerTechnics has been selected as a system semiconductor material, parts, and equipment (SoBuJang) item for electric vehicle inverters, one of the three major new industries (BIG3) fostered by the Ministry of Trade, Industry and Energy. Once development is completed, it is expected to mass-produce products and supply them to domestic automakers in line with the purpose of the domestic demand-supply company cooperation project.
According to market research firm IHS Markit, the SiC power semiconductor market size is expected to grow from about 700 million USD last year to 10 billion USD by 2030. Recently, as the global automotive industry has faced semiconductor supply shortages, the necessity for domestic production has been raised.
