Justem (417840.KQ), a leading semiconductor humidity control solutions provider, posted its best-ever first-quarter results.
The company's consolidated revenue and operating profit for the first quarter of 2026 rose 67% and 147% from a year earlier, respectively, Justem said Wednesday.
Revenue climbed 67% to 17.69 billion won. Operating profit surged 147% to 4.07 billion won, marking a quantum jump. Operating margin improved significantly to 23%, up from 15.5% in the same period a year earlier.
The earnings surprise was driven by the expansion of advanced semiconductor processes at integrated device manufacturers. The three major IDMs are focusing on yield improvement amid explosive demand for DRAM and high-bandwidth memory (HBM). Justem's humidity control solutions, recognized as a technology that contributes to yield improvement, are seeing growing adoption.
Justem projected that demand in the global semiconductor market will continue its upward trend. Semiconductor companies are currently expanding new production lines, which are expected to take at least two to three years to complete.
"These results once again confirm through numbers that Justem's solutions are a necessary and sufficient technology for yield enhancement across all advanced processes in both existing and new lines," Justem CEO Kim Yong-jin said. "We will strive to make 2026 a year of quantum jump, achieving the best results since our founding."
