Doosan's acquisition of SK Siltron is rapidly approaching its final stages, with expectations of completion in the first half of 2026.
This deal is more than just a simple acquisition; it's a strategic move to create a powerful, vertically integrated value chain in the semiconductor industry. Imagine a seamless flow: Doosan Electronics produces the core material, CCL (Copper Clad Laminate), SK Siltron manufactures the essential wafers, and Doosan Tesna handles the final testing. This integration gives Doosan significant control over its supply chain, enhancing both efficiency and bargaining power, especially as the demand for AI semiconductors continues to surge.
So, what events have led us to this point? The journey has been methodical. First, Doosan secured its position as the preferred bidder in late 2025 and proactively raised capital, partly by selling shares in Doosan Robotics. This demonstrated a clear and strong commitment to financing the deal. Second, the company and its affiliates announced major investments, including a new CCL plant in Thailand and significant equipment upgrades at Doosan Tesna. These actions weren't just about spending money; they were tangible steps to prepare for the synergies the acquisition would bring. Finally, this all happened against a backdrop of a booming market, with industry forecasts predicting double-digit growth in demand for 300mm wafers, driven by AI and HBM technologies.
However, a few key hurdles remain before the deal is officially closed. A recent impairment loss in SK Siltron's SiC wafer business has introduced a new variable into the price negotiations, potentially lowering the final price or adding protective clauses. Furthermore, the acquisition requires approval from the Korea Fair Trade Commission (KFTC), a process that has a standard timeline but can be extended. Lastly, concerns from the labor union about employment and working conditions could also influence the final terms of the agreement.
Despite these challenges, the strategic logic behind the acquisition remains compelling. The market has already reacted positively, with Doosan's stock price showing significant gains. This reflects a strong belief that the creation of this semiconductor value chain will unlock substantial growth and position Doosan as a key player in the global AI hardware race.
- CCL (Copper Clad Laminate): An essential base material used to manufacture printed circuit boards (PCBs), which are foundational components in most electronic devices.
- Wafer: A thin, circular slice of semiconductor material, typically silicon, that serves as the substrate for fabricating microelectronic circuits, or chips.
- Vertical Integration: A business strategy where a company acquires other companies operating before or after it in the supply chain. In this case, Doosan is integrating a material supplier (CCL), a component manufacturer (SK Siltron), and a service provider (Tesna).
