Koh Young Technology posted first-quarter revenue of 72.7 billion won and operating profit of 9.9 billion won. Revenue rose 42 percent and operating profit jumped 209 percent from a year earlier.

The company said in a regulatory filing on April 23 it achieved record first-quarter sales, helped by expanding demand for 3D inspection equipment and smart factory software led by global AI customers. Net profit came to 15.7 billion won, up 389 percent from a year earlier. It was record first-quarter revenue.

Growth was also clear from the previous quarter. Compared with the previous quarter’s revenue of 69.1 billion won and operating profit of 6.9 billion won, revenue rose 5.2 percent and operating profit increased 41.9 percent.

The improvement was driven by expanded investment in AI infrastructure. As demand for AI servers increased, production of high-performance semiconductors and high-speed optical interconnects rose, boosting demand for 3D precision inspection technology to secure yields.

Koh Young expanded supplies of 3D semiconductor packaging inspection equipment to a global No. 1 AI data centre optical communications module customer. The company said that increased inspection equipment sales to AI customers was the direct reason for the rise.

AI smart factory software also drove growth. As new investment expanded among AI server customers, demand increased for manufacturing process automation, and supplies of Koh Young’s process monitoring, diagnosis, analysis and optimisation solutions also rose.

A key feature of the results was that demand expanded at the same time for two pillars: 3D inspection equipment and AI smart factory software. The company said the improvement in profitability far outpaced the rate of revenue growth, and that this was not unrelated.

A Koh Young official said, "As adoption of 3D inspection equipment and AI smart factory solutions is increasing at the same time among global AI customers, we expect the growth trend to continue."
