President Lee Formalizes 'Honam Semiconductor Mega Investment': Securing 1M Tons of Water and Beneficiary Stocks Outlook

President Lee Jae-myung has officially hinted at a mega investment to build a large-scale semiconductor complex in the Honam region, confirming that the supply of '1 million tons of industrial water'—the biggest hurdle—will not be an issue. This is a bold move to simultaneously achieve balanced national development and RE100 (100% Renewable Energy), providing new momentum for semiconductor materials, parts, and equipment (SME) and infrastructure stocks in the highly volatile KOSPI market.

Background of Honam Semiconductor Mega Investment & Market Impact

With the urgent need for domestic large semiconductor companies to expand their production capacity due to the recent explosion in AI semiconductor demand, the establishment of the 'Honam Semiconductor Cluster' is imminent. President Lee Jae-myung showed a strong will to actively support the mega investment for new semiconductor lines in the Honam region, emphasizing that the core infrastructure of the semiconductor plant, a daily supply of 1 million tons of ultrapure water (UPW) and industrial water, can be perfectly established through the integration and adjustment of dams in the Yeongsan and Seomjin River basins.

The Honam region is evaluated as the most advantageous location for achieving RE100, which global companies demand, due to its abundant sunlight and offshore wind resources. Market experts analyze that as investments, previously concentrated in the Yongin cluster, diversify to Honam, regional construction and civil engineering companies, as well as smart water grid and power equipment companies, will be the primary beneficiaries. Amidst the KOSPI's large tech stocks experiencing heightened volatility due to global fundamental concerns, this domestic infrastructure and mega investment news is emerging as a strong theme supporting the downside of the stock market.

FAQ: 3 Key Questions About the Honam Semiconductor Cluster

Q1. Why is the Honam investment necessary when there is already a cluster in the metropolitan area (Yongin)?

The metropolitan area is facing limitations in power grid saturation and land acquisition. In contrast, the Honam region has vast industrial sites secured and, most importantly, abundant renewable energy infrastructure such as solar and offshore wind power, making it the most suitable environment to meet the RE100 standards set by global big tech companies like Apple and Google.

Q2. How will the '1 million tons of industrial water' essential for semiconductor production be resolved?

The government plans to improve existing agricultural weirs and retention facilities and build an integrated management network for 7 dams in the Yeongsan and Seomjin River systems. In addition, by maximizing the ratio of reused sewage water, it has presented a detailed blueprint to stably supply more than 1 million tons of water per day without drought risks caused by climate change.

Q3. Which stock market sectors will benefit from this mega investment announcement?

In the short term, stocks related to construction, cables, power equipment, and water resource infrastructure (steel pipes, water treatment facilities) that build factory sites, water, and power grids are expected to benefit. In the mid-to-long term, a valuation rerating is expected for semiconductor equipment and material partners that will establish new bases in the Honam region.
