Doosan Electronics Sales Hit 802 Billion Won on AI Demand

Doosan Corp.'s electronics business posted quarterly sales of 802 billion won in the third quarter, an all-time high, as global artificial intelligence infrastructure investment expanded and the company closed in on its acquisition of wafer maker SK Siltron.

Doosan announced on the 9th that third-quarter consolidated sales reached 5.43 trillion won and operating profit 459.4 billion won. Sales rose 22.2 percent and operating profit 98.4 percent from a year earlier. The gains came from improved earnings at its own businesses and major affiliates.

Analysts read the results as early progress in building a value chain across semiconductor upstream and downstream industries. The SK Siltron acquisition, a deal for the wafer manufacturer, closes at the end of January. That timing matters. The record quarter is not yet proof the chain works end to end.

What drove the record quarter?

Doosan's own businesses, distinct from affiliates, posted sales of 892.2 billion won and operating profit of 237.9 billion won. Both figures set a high bar: sales up 70.2 percent and operating profit up 119.6 percent from a year earlier.

The Electronics Business Group carried the quarter. Key products — components for AI accelerators, memory and optical modules (devices converting electrical signals to light for data transmission) — all sold more on expanding AI infrastructure spending.

For scale: electronics now accounts for roughly 90 percent of the sales of Doosan's own businesses, a concentration that cuts both ways if AI capex slows.

Can the fourth quarter top it?

Doosan expects another quarterly record of 814.6 billion won in electronics sales for the fourth quarter. On that basis, annual sales from the Electronics Business Group alone would exceed 2.9 trillion won.

"Growth will continue in the fourth quarter, led by the Electronics Business Group, and annual sales from our own businesses will exceed about 3.2 trillion won," the company said.

Note the gap. The company's own forecast implies the rest of its businesses contribute under 300 billion won of the annual total. The growth story is, in practice, a single-division story.

What about the copper clad laminate investment?

Doosan said it will invest about 970 billion won at home and abroad through 2028 to meet rising demand for copper clad laminate (CCL), the insulating base material used to build printed circuit boards. The plan targets production capacity at 2.7 times current levels by 2029.

The company maintained its outlook for AI data center expansion even after the Democratic Party's sweeping win in the U.S. midterm elections. That is a position, not a guarantee. U.S. policy shifts remain the unpriced variable in every AI-capex projection issued this quarter, and Doosan's statement does not address tariff or subsidy risk.

How did the affiliates perform?

Doosan Enerbility (034020) posted third-quarter consolidated sales of 4.45 trillion won and operating profit of 261.2 billion won, up 14.7 percent and 90.6 percent respectively. Cumulative orders through the third quarter reached 9.999 trillion won — a figure one won short of 10 trillion, a rounding artifact worth noting.

Its key projects include:

• Construction of the Misfah gas combined-cycle power plant in Oman
• A contract to manufacture core components for TerraPower's small modular reactor (SMR), a compact nuclear design
• Construction of the Hadong combined-cycle power plant
• Construction of the O Mon 3 gas combined-cycle power plant in Vietnam

Doosan Bobcat (241560) posted third-quarter sales of 2.46 trillion won and operating profit of 167.4 billion won. Sales rose 16.5 percent and operating profit 25.3 percent from a year earlier on broad-based growth across all regions and product lines.

By product, compact equipment sales rose 15 percent, industrial vehicles 8 percent and portable power 5 percent. By region, North America grew 15 percent, Asia, Latin America and Oceania (ALAO) 14 percent, and Europe, the Middle East and Africa (EMEA) 3 percent.

What is not in the announcement?

Doosan did not disclose segment operating profit for the Electronics Business Group, so margins remain unverifiable from this release. The 970 billion won CCL investment lacks a capacity breakdown by site, and the SK Siltron integration costs are absent from the projection.

The numbers are strong. The company has backed them with a capacity plan and a closing date for its wafer acquisition. What it has not yet shown is whether electronics demand holds once AI infrastructure spending normalizes — and no quarterly record answers that question.
