JUNJIN Construction Robot's stock price has plummeted, marking its largest drop since the company went public in August last year.

JUNJIN Construction Robot shares were traded at 41,100 won on the KOSPI market at 2:16 p.m. on the 31st. The stock price dropped by 11.61% (5,400 won) compared to the previous trading day. The largest drop prior to this occurred on Nov. 29 last year, when the stock price fell by 10.61% (3,150 won). If the current stock price level continues until the close, it will record the largest drop.

JUNJIN Construction Robot is the largest concrete pump truck (CPC) manufacturer in South Korea. Over 60% of its revenue comes from the U.S. and European markets, which is why it has been recognized as a beneficiary of rebuilding efforts in Ukraine and post-wildfire recovery projects in Los Angeles, California.

However, it seems investors are selling JUNJIN Construction Robot shares due to concerns that investments in U.S. regional infrastructure may lag. This concern has arisen following the introduction of a cost-effective model by the Chinese artificial intelligence startup DeepSeek, which has led to worries that data center investments may decrease more than expected.

The mandatory holding registration amount of the largest shareholder of JUNJIN Construction Robot (MOTREX JUNJIN No. 1 Stock Company) will also be released on the 19th of next month. The proportion of released shares compared to the total number of issued stocks is 21.57% (3,147,675 shares).
