Mingteng International Corporation Inc. (Nasdaq: MTEN) saw its stock price skyrocket 81.3% on Monday, closing at $1.94, after the company announced it had terminated its at-the-market (ATM) share sale program. The move came as a surprise to many investors, given the company's small market capitalization and recent financial performance.
The China-based automotive mold supplier said in a regulatory filing that it ended the ATM agreement with AC Sunshine Securities on June 8, after selling approximately 222.6 million Class A ordinary shares under the program. This figure does not account for the 1-for-200 reverse stock split completed in January. The company reported net proceeds of around $18.0 million from the sales, with gross proceeds totaling about $20.6 million.
Mingteng's shares traded in a wide range during the session, between $1.05 and $5.34, with volume surging to 24.2 million shares. This trading activity dwarfed the company's market value of roughly $12 million, highlighting the extreme volatility typical of microcap stocks. The sharp price movement outpaced gains in other U.S.-listed Chinese auto and tech stocks, such as China Automotive Systems (up 1.1%), Kandi Technologies (up 4.8%), and Hesai Group (up 3.5%).
The broader market also saw gains on Monday, with the Nasdaq Composite rising 0.86% and the S&P 500 adding 0.30%, driven by a rebound in technology and chip stocks. However, Mingteng's rally was far more dramatic, reflecting the company's low liquidity and small float.
Mingteng specializes in manufacturing molds for automotive components, including casting molds for turbochargers, braking, steering, and differential systems, as well as products for new-energy electric vehicle systems. Its production facilities are located in Wuxi, China. The company has been restructuring its share capital this year, implementing a 1-for-200 reverse stock split in January to boost its share price, a common tactic for low-priced stocks to maintain listing requirements on the Nasdaq Capital Market.
In January, Mingteng also announced the completion of a move to a new production site, with plans to increase mold output capacity by 50%. Chairman and CEO Yingkai Xu described this as a "key milestone" for the company's medium- and long-term growth plans. However, the company's financial performance remains mixed. For the full year 2025, Mingteng reported revenue of $11.7 million, up 15.3% from the prior year, driven by mold production and machining. Despite the revenue growth, the company posted a net loss of $1.8 million, and its gross margin contracted to 22.5% from 30.3% due to rising material, labor, and manufacturing costs.
The stock's surge appears to be driven more by the cessation of the ATM program rather than any fundamental improvement in the business. The company's latest filing referenced past share sales, not new orders or earnings growth. Mingteng also faces customer concentration risk, with two buyers accounting for approximately 22.1% and 18.4% of 2025 revenue, respectively, according to its annual report. Investors should be cautious, as the stock's price action may be disconnected from the underlying business reality.
