1. What Happened?

On July 28, 2025, Gwangmyeong Electric responded to the Korea Exchange’s inquiry regarding its recent stock volatility. The key takeaway is the potential change in the largest shareholder’s stake and the review of multiple disclosures. The company confirmed the sale of shares by its largest shareholder, MH Construction Co., Ltd., which is believed to be the primary driver of the recent stock plunge. Adding to the uncertainty are the company’s poor Q1 performance and the postponement of its tangible asset acquisition plan.

2. Why Did This Happen?

Gwangmyeong Electric reported dismal Q1 results, with revenue down 53% year-over-year and an operating loss of 3.9 billion KRW. The underperformance of the switchgear division, rising raw material costs, and intensifying global competition are cited as key factors. The situation is further exacerbated by external headwinds such as a rising KRW/USD exchange rate, sustained high interest rates, and a global economic slowdown.

3. What’s Next?

The upcoming Q2 earnings report, scheduled for release on August 14th, and further disclosures regarding the largest shareholder’s stake will be critical in determining the stock’s trajectory. The purpose and scale of the stake sale could significantly impact stock volatility. If the sale is related to a change in management or financial difficulties, further declines are likely.

4. What Should Investors Do?

Investors should proceed with caution. Carefully analyze the company’s fundamentals and future outlook following the Q2 earnings release before making any investment decisions. Closely monitor further disclosures and market developments, and prioritize risk management. Pay particular attention to risks associated with the company’s PF projects and any shifts in its management strategy.
