Seokyung AT Announces Preliminary 2025 Results: Sales Up 27%, Operating Profit Up 92.7%

Seokyung AT , a nanomaterials specialist, announced its preliminary 2025 earnings. Consolidated sales reached KRW 17.5 billion and operating profit reached KRW 3.9 billion, representing year-on-year increases of 27% and 92.7%, respectively.

The performance improvement was driven by increased domestic and international sales of dental materials, including 3D printing materials, and toner additives. Profitability and cost structure stabilized, driven by a reduction in fixed costs due to increased sales and a reduction in certain one-time expenses, such as commissions. The annual operating profit margin reached 22.2%, up 7.5 percentage points year-on-year.

The second half of the year saw increases in depreciation and operating expenses due to the operation of the Gimje 3rd factory. A fire at the Yeongam 2nd factory in May resulted in temporary restoration costs, but customer supply remained stable thanks to an alternative production system at the headquarters plant. With restoration now complete, most related costs have been resolved.

In addition to the stable growth of dental materials and toner additives, Seokyung AT announced that new applications for its high-performance silica materials for semiconductor packaging are expanding, and active testing is underway with numerous customers in processes requiring low CTE and high functionality. In 2026, sales in high-value-added areas such as cosmetics materials, hollow silica, and semiconductor packaging materials are expected to gradually be reflected.
