Justem said on Tuesday it posted first-quarter 2026 consolidated revenue of 17.69 billion won and operating profit of 4.07 billion won. Revenue rose 67 percent from a year earlier and operating profit climbed 147 percent. It achieved an operating margin of 23 percent.

Revenue came to 17.69 billion won, up 67 percent from 10.62 billion won a year earlier. Operating profit was 4.07 billion won, up 147 percent from 1.65 billion won.

Net profit totalled 4.61 billion won. It jumped about 200 percent from 1.54 billion won a year earlier. The operating margin rose to 23 percent from 15.5 percent.

The company said the rapid growth was driven by expanded investment in yield-improvement processes by 3 integrated device manufacturers. As demand for DRAM and high-bandwidth memory surged, IDM companies are focusing on maximising yields at existing lines, and Justem's humidity-control solution directly absorbed that demand, it added.

Semiconductor segment revenue was 16.63 billion won, accounting for 94 percent of total revenue and leading the growth. The remaining 6 percent came from other segments such as display and solar power, totalling 1.06 billion won.

Justem sees it taking at least 2 to 3 years for IDMs to complete new line expansion capital expenditure. With maximising yields a practical way to increase supply during that gap, the company judges demand for humidity-control solutions will continue.

Raising yields is the top priority for improving productivity at new lines currently under construction. The company said it expects supplies of its products to continue for both existing and new lines.

Chief Executive Kim Yong-jin (김용진) said the first-quarter results once again confirmed in numbers that Justem's solutions are necessary and sufficient technology for improving yields across all advanced processes at existing and new lines. He said the company would work to make 2026 a year of a quantum jump to achieve its best results since its founding.
