Mec Company Ltd (TSE: 4971), a Hyogo-based maker of chemical additives for circuit boards, told Japan's securities regulator that consolidated sales for the six months to June 2026 rose 34.2% to ¥12.59bn, from ¥9.39bn a year earlier. Operating profit climbed 69.4% to ¥4.14bn, pushing the operating margin to 32.8%, up from 26.0% in the same period last year. Net profit attributable to shareholders rose 60.5% to ¥3.04bn.
The gains track demand for Mec's chemical treatments used to prepare semiconductor packaging substrates for the dense wiring that generative-AI processors and memory chips require. Chemical sales, the company's largest business line, rose 37.4% to ¥12.4bn and reached a quarterly sales record within the half, driven mainly by the company's CZ-series ultra-roughening adhesion promoters, used on advanced packaging and memory-related substrates. Two smaller product lines, the V-Bond adhesion promoter for multilayer boards and the EXE fine-wiring product, also grew on display and fine-wiring demand; the SF-series line declined as demand softened for the end products it serves.
| Region | Sales | Sales Change | Segment Profit | Profit Change |
|---|---|---|---|---|
| Japan | ¥4.56bn | +36.2% | ¥3.35bn | +120.6% |
| Taiwan | ¥2.33bn | +28.3% | ¥275.8mn | +30.4% |
| Zhuhai (China) | ¥1.81bn | +44.7% | ¥259.3mn | +83.1% |
| Suzhou (China) | ¥2.32bn | +34.3% | ¥324.2mn | +71.1% |
| Thailand | ¥804.6mn | +74.9% | ¥112.3mn | +66.0% |
| Europe | ¥768.6mn | -1.8% | ¥158.9mn | +86.3% |
Every region except Europe posted higher sales. Japan sales rose 36.2% to ¥4.56bn and segment profit more than doubled, up 120.6% to ¥3.35bn, helped by both direct generative-AI-linked packaging demand and Korea-bound sales routed through domestic agents for memory packaging substrates. Thailand grew fastest in percentage terms, up 74.9% to ¥804.6mn, as electronics makers expand and start up plants in Southeast Asia. Europe was the outlier, down 1.8% to ¥768.6mn, as a one-off materials order that had boosted the prior year's comparison did not repeat.
Overseas sales made up 66.0% of the total, down slightly from 66.4% a year earlier; including overseas customers served through Japanese trading agents, the overseas share rose to 82.0% from 80.8%.
Total assets grew by ¥7.78bn from the end of last year to ¥44.21bn, reflecting gains in the value of investment securities held and rising construction-in-progress spending tied to a new plant in Kitakyushu. The equity ratio eased to 81.7% from 83.7% at the last fiscal year-end. Mec's board declared an interim dividend of ¥55 a share, payable September 1 to shareholders on record as of June 30, after paying a year-end dividend of ¥71 a share in March. The filing covers the company's 58th interim accounting period, submitted to the Kinki Local Finance Bureau on August 12.
