Strategic Impact Analysis of POSCO's $582 Million US Plant Investment

According to the latest data, Hyundai Steel announced an investment of $5.8 billion to build an integrated electric arc furnace (EAF) steel plant in Louisiana with an annual capacity of 2.7 million tons, scheduled to start production in 2029 [2]. POSCO will participate in this investment; although the specific investment amount has not been publicly disclosed, it is reported to be approximately $582 million.

: POSCO clearly stated that through this investment, it will “secure a bridgehead to enter the North American steel market, which has been restricted by protectionist trade barriers over the past decade” [1]. The U.S. will impose a 25% tariff on all imported steel starting March 12, 2025 [1], making localized production a key strategy.

: POSCO currently operates steel processing centers in North America (U.S./Mexico), including an automotive steel mill (POSCO-Mexico). This investment will enable it to establish a flexible global production and sales system, ensuring smooth material supply to the U.S. and Mexico regions [2].

: The plant uses advanced electric arc furnace technology, which is more environmentally friendly than traditional blast furnace processes, significantly reducing the carbon footprint of automotive steel sheet production. This aligns with the global carbon neutrality trend, especially valuable under the U.S. IRA Act subsidy policy.

: The annual capacity of 2.7 million tons will bring significant cost advantages while providing stable localized supply to other vehicle manufacturers.

: Hyundai Motor Group plans to invest $21 billion in the U.S. between 2025 and 2029 to expand automobile production, among which the construction of an EAF steel plant by its steel subsidiary Hyundai Steel is an important component [1]. POSCO’s participation further strengthens this vertical integration strategy.

: The two parties also signed a memorandum of understanding for “mutual cooperation in steel and secondary battery fields”. POSCO will leverage its competitiveness in secondary battery materials business to establish a stable supply chain and develop next-generation materials [1].

: POSCO’s entry into the U.S. market will provide EV manufacturers with more localized steel supply options, reducing reliance on imports. Manufacturers like Tesla face requirements under the U.S. IRA Act and need more localized supply chains to qualify for subsidies.

: POSCO is collaborating with U.S.-based ReElement Technologies to establish rare earth and magnet production, specifically for EV powertrains and electronic components [4]. As a top supplier, POSCO’s drive motors and transformers have obtained certifications from customers in the U.S., South Korea, Europe, and Japan [5], laying the foundation for deep collaboration with manufacturers like Tesla.

: POSCO is collaborating with U.S. Energy Fuels to create a “China-excluded” rare earth magnet supply chain [5], which aligns perfectly with the strategic needs of U.S. EV manufacturers like Tesla to diversify their supply chains.

According to the latest data, POSCO Holdings Inc. (005490.KS) has a market capitalization of 23.29 trillion KRW and a current stock price of 308,000 KRW [0]. Its stock price has performed strongly this year, rising 23.20% year-to-date, reflecting market recognition of its strategic transformation.

Analysts maintain a buy rating on the stock, with 37.5% of analysts giving a buy recommendation [0]. Amid a low valuation environment (P/B ratio of only 0.46x), the company is laying the foundation for long-term growth through U.S. market expansion and EV industry chain layout.

: This investment marks an important step for traditional steel giants to transform into new energy materials and new material suppliers, no longer limited to traditional automotive steel supply.

: This investment also reflects the trend of strengthened industrial cooperation between South Korea and the U.S. in key material fields, especially against the backdrop of the U.S. promoting supply chain reshoring and intensifying Sino-U.S. tech competition.

POSCO’s this investment is not only supporting Hyundai Motor Group but also a key step in its globalization strategy and new energy material layout. By establishing a steel production base in the U.S. and deepening collaboration with EV manufacturers, POSCO is expected to:

1. Significantly enhance competitiveness and market share in the North American market
2. Strengthen its strategic position in the EV supply chain
3. Achieve transformation from a traditional steel enterprise to a new material solution provider
4. Occupy a favorable position in the low-carbon transformation of the global steel industry

This investment will profoundly impact the global steel industry pattern and EV supply chain layout, creating new growth opportunities for POSCO in its supply chain relationships with EV manufacturers like Tesla.
