⚠️ POSCO Holdings: Strikes, Interest Rates, and Governance Variables Converge - 2026.09.10

Hi, it’s Peanut. With POSCO’s 48-hour partial strike underway, POSCO Holdings closed on September 10 at ₩339,000. The number alone shows a 0.59% gain, but when steel-industry conditions and operational risks are considered together, it is worth asking whether the situation is really that positive. ^{[1] [5]}

📉 Operational Variables to Watch Before the Share-Price Rebound

As the POSCO labor union failed to reach an agreement in wage negotiations, it began a 48-hour first partial strike from 7 a.m. on September 9 to 7 a.m. on September 11. Reports pointed out that POSCO’s 58-year no-strike tradition had been broken and that this could also weigh on the leadership of POSCO Holdings Chairman Chang In-hwa. ^[1]

What matters here is not the word “strike” itself, but that the operational stability of the steel business and the negotiation process are being tested at the same time. The specific impact on company earnings is difficult to verify from the available materials alone, but it needs to be viewed alongside the fact that industry conditions are not exactly comfortable already. Even if the share price rebounded in a single day, it is difficult to say that the company’s fundamental strength changed at the same pace.

💼 Interest-Rate Sensitivity Confirmed in the Numbers

Reports also said that high interest rates are slowing steel demand and increasing interest burdens. In last year’s business report, POSCO Holdings projected that a 1-percentage-point increase in the interest rate on borrowings under variable-rate terms could reduce net income by 62,100,000,000 KRW. ^[2]

This does not mean the company has confirmed that such an outcome actually occurred; it is conditional sensitivity disclosed in the business report. Still, it is clear that the interest-rate variable was presented as an item that could be connected to profit and loss, rather than merely a market slogan. This is why, when reviewing PER or PBR, it is necessary to examine interest expenses and borrowing conditions alongside steel-industry conditions. One number has quite a lot to say.

⚠️ Legal Dispute and Governance Schedule

In the dispute over responsibility for the bankruptcy of POSCO in Brazil, allegations emerged that 1.5 million reais had been offered to prevent testimony. Reports also said that, in the relevant proceedings, a Brazilian court addressed for the first time the influence of POSCO Holdings, the parent holding company above POSCO Korea. ^[3]

However, this concerns reports about allegations and court proceedings. It should not be read as confirmation of liability, and future legal judgments and the company’s explanation remain key variables. Such legal uncertainty may be cited as a discount factor in the value of a holding company in addition to business performance, but the current materials do not justify calculating a specific amount.

POSCO Holdings is also approaching the expiration of the terms of eight directors in 2027. According to the latest corporate governance report, the board has 12 members in total: seven independent directors, four internal directors, and one other non-executive director. ^[4] As changes to the board’s composition approach, governance issues may develop into a medium-term valuation question rather than remain one-off news.

🛑 Questions That Remain in the Valuation

For short- to medium-term swings, the daily percentage change catches the eye, but from a fundamental-investor perspective, it is more important that the strike period, interest-rate sensitivity, legal dispute, and 2027 board changes are not moving independently. If expectations for steel and secondary-battery materials become too large in a bullish environment, the risk of a value trap may also emerge. Can those expectations really be validated through earnings and cash flow?

Peanut sees the current share price as being in a period where operational, interest-rate, and governance variables overlap, making it difficult to judge based on a one-day rebound alone. The questions ahead are how the strike will be resolved, how interest-rate sensitivity will appear in actual earnings, and how the Brazilian proceedings and board changes will affect the value of the holding company.
