Japan's trading house Sojitz has signed a memorandum of understanding to acquire a 5% stake in Vietnam's Masan High-Tech Materials, a key supplier of tungsten used in semiconductors and advanced technology. The deal, announced by Masan Group, would see Sojitz buy the stake from Masan's wholly owned unit Masan Horizon, with final agreements expected by the end of the year, subject to due diligence and regulatory approvals.
The pricing is the standout detail. Masan said the price would not be lower than the valuation set by a recent deal involving Elmet Group. In September, Masan High-Tech Materials agreed to sell a 4.99% stake to Elmet Group, a transaction that valued the business at roughly $2.5 billion. That implies about $125 million for the 5% slice Sojitz is eyeing, though the final price could be higher.
Masan Group will retain control of the tungsten unit after the deal, which is structured as a minority investment. The move is part of a broader strategy by Masan to bring in strategic partners who can help expand its customer base and strengthen its position in the global supply chain for critical minerals.
Why tungsten matters for chips and AI
Tungsten is a hard, dense metal with the highest melting point of any element, making it essential in a range of industrial applications. In the electronics world, it is used to create the tiny interconnects and contacts inside semiconductors, as well as in the manufacturing equipment that produces chips. As demand for artificial intelligence infrastructure surges, so does the need for advanced chips, and that in turn drives demand for tungsten.
Sojitz, one of Japan's major trading houses, is looking to secure a reliable supply of this critical material for its Japanese customers, which include chipmakers and companies building AI data centers. By taking a direct stake in the producer, Sojitz gains more than just a financial return; it gains a seat at the table when it comes to supply negotiations and long-term planning.
The deal also highlights the growing strategic importance of tungsten. The Pentagon's backing of Elmet Group, which is a U.S.-based company, underscores how governments view tungsten as a critical mineral for national security and technological leadership. That geopolitical dimension adds another layer of significance to the transaction.
What it means for investors
For everyday investors, this deal is a reminder that the supply chain for advanced technology is increasingly global and strategic. Companies like Sojitz are not just trading commodities; they are investing directly in producers to lock in access to materials that are vital for the digital economy.
The fact that Sojitz is willing to match the valuation set by Elmet suggests that the market for tungsten assets is heating up. It also signals confidence in the long-term demand outlook for chips and AI infrastructure, even as tech stocks have experienced volatility recently. For context, Japan's Nikkei index plunged 5% in a recent tech-led selloff, and AI favorites led the decline, but this deal indicates that industrial players are still making long-term bets on the sector.
For Masan, the deal provides a cash infusion and a strategic partner that can help open doors in the Japanese market. It also validates the value of its tungsten business, which is a key part of its portfolio alongside consumer goods and other materials.
Investors should watch for the final terms of the agreement, including the exact price per share and any conditions that might affect the closing. The deal is expected to close by the end of the year, but due diligence and regulatory approvals could cause delays. Also worth noting is that Masan will remain in control, so this is a minority stake that does not change the company's strategic direction.
For those interested in the broader theme of critical minerals and supply chain security, this deal is a clear example of how companies are positioning themselves. Similar moves have been seen in other sectors, such as Alphabet's investment in Qualcomm to support its AI data-center push, and Permira's acquisition of a majority stake in Flint Group in the home services space. These deals show that strategic investments are a common way for companies to secure resources and capabilities.
In the end, the Sojitz-Masan deal is a small but telling sign of how the global economy is adapting to the demands of the AI era. Tungsten may not be as flashy as a new chip design, but it is just as essential. And for investors, understanding these supply chain dynamics can offer valuable insight into where the technology sector is headed.
