SMIC to add wafer capacity to meet strong chip demand, warns of margin hit

Semiconductor Manufacturing International Corp (SMIC), China’s largest contract chipmaker, announced during its quarterly earnings briefing on February 7, 2024, that it will aggressively expand its wafer production capacity to meet surging domestic demand. Despite the high interest in local silicon, the Shanghai-based firm warned investors that this capital-intensive expansion, coupled with fierce global competition, will likely result in significantly narrowed profit margins throughout the coming year. The company is positioning itself as a critical pillar for China’s technological self-sufficiency amid ongoing trade tensions and international export controls. The strategic pivot comes as the semiconductor industry faces a bifurcated recovery; while high-end AI chips are in short supply, the market for mature-node chips—where SMIC primarily operates—is witnessing a glut that exerts downward pressure on pricing. To counter this, SMIC plans to increase its capital expenditure to bolster its 12-inch wafer production lines. Management emphasized that maintaining a dominant market share in mainland China is a priority that currently outweighs short-term profitability, as the nation seeks to insulate its supply chain from external geopolitical shocks. Industry analysts note that SMIC's warning reflects a broader trend among Chinese foundries that are prioritizing infrastructure growth over financial efficiency. By adding capacity now, the company aims to capture the long-term domestic transition toward home-grown hardware in the automotive and consumer electronics sectors. However, the immediate financial outlook remains cautious, with the company forecasting a low-to-mid single-digit drop in gross margins as depreciation costs from new equipment begin to hit the balance sheet. This aggressive expansion strategy underscores the complex balancing act between achieving national strategic goals and maintaining corporate financial health in a volatile global market.
