LX Semicon (108320.KQ), Korea's largest fabless chip designer, is facing a "structural crisis" that goes beyond a mere industry downturn, analysts say. Demand for its core display driver ICs (DDI) has frozen, while its key customer bases at Apple and LG Display are being shaken by aggressive competition from Taiwan and China.
According to financial information provider FnGuide on the 27th, LX Semicon's first-quarter revenue and operating profit are projected at 436 billion won and 27 billion won, respectively, ahead of its preliminary earnings release on the 30th. If realized, these figures would represent a 10.9% drop in revenue and a 54.7% plunge in operating profit from a year earlier — a performance at the level of an earnings shock.
The surface-level reason for the weak performance is a chill in TV and smartphone demand. With high interest rates persisting and device prices rising due to chipflation (semiconductor price increases), consumer sentiment is rapidly cooling.
The bigger problem is a tectonic shift in the display supply chain ecosystem. The situation changed abruptly after LG Display, a key customer that had served as a pillar, sold its LCD plant in Guangzhou, China, to local player CSOT. A significant portion of the large-sized LCD DDI volume that LX Semicon had virtually monopolized is now at risk of being taken away. Chinese panel makers are following an internalization strategy that gives preference to domestic fabless components.
The onslaught from Taiwanese rivals is also fierce. Taiwan's Novatek, armed with aggressive price-cutting policies, has penetrated deeply into LX Semicon's major supply chains, including Apple and China's BOE. Major set and panel customers are breaking single-supplier systems and pursuing dual-sourcing (diversification) policies to cut costs and stabilize supply chains. LX Semicon's share in small DDI, which fell by half last year, is expected to decline further to around 45% this year.
As growth in its core business hits a wall, mergers and acquisitions (M&A) are emerging as an alternative. Fortunately, investment capacity is sufficient. As of the end of 2025, LX Semicon's available cash, combining cash and cash equivalents (178.1 billion won) and short-term financial instruments (270.4 billion won), totals 448.5 billion won. Its debt ratio is only 24.4%, indicating a sound financial position. Industry sources estimate that if external funding such as borrowings is mobilized, M&A funds available would approach at least 1 trillion won.
The key is the method and pace of investment. Based on its abundant liquidity, LX Semicon is intensively seeking non-display new growth engines, including automotive heat-dissipation substrates that recently entered mass production, microcontroller units (MCU), and next-generation power semiconductors. "LX Semicon will attempt to expand into the automotive electronics and vehicle semiconductor ecosystem to reduce its dependence on DDI, which has hit its limits," an investment banking (IB) industry official said.
