Nitto Boseki, the Tokyo-listed maker of specialty glass fiber and materials, posted a sharp rise in first-quarter profit and used the results to raise its full-year earnings forecast, pointing to demand for glass materials used in AI servers and semiconductor packaging.
For the three months to June 30, 2026, consolidated net sales rose 20.6% to ¥34.0bn, operating profit climbed 84.8% to ¥7.9bn, and net profit attributable to parent-company shareholders rose 84.2% to ¥5.8bn. Comprehensive income, which captures currency and securities-valuation swings alongside operating results, jumped 809.2% to ¥7.5bn, rebounding from just ¥825mn a year earlier, when it had fallen 82.6%.
The gains centered on the company's Electronic Materials segment, where sales rose 29.5% to ¥14.6bn and operating profit rose 70.0% to ¥7.0bn. Nitto Boseki said the segment benefited from continued growth in demand for low-dielectric special glass and low-thermal-expansion special glass used in semiconductor package substrates for AI servers, together with the effect of price revisions.
On the strength of those results, the company raised its full-year guidance for the year ending March 2027, now expecting operating profit of ¥30.0bn and net sales of ¥141.0bn.
| Metric | Previous forecast | Revised forecast | Change |
|---|---|---|---|
| Net sales | ¥137.0bn | ¥141.0bn | +¥4.0bn (+2.9%) |
| Operating profit | ¥26.0bn | ¥30.0bn | +¥4.0bn (+15.4%) |
| Ordinary profit | ¥26.0bn | ¥30.0bn | +¥4.0bn (+15.4%) |
| Net profit attributable to parent | ¥17.0bn | ¥20.0bn | +¥3.0bn (+17.6%) |
The company also lifted its guidance for the six months to September 2026, raising expected operating profit to ¥15.3bn from ¥12.6bn and net sales to ¥69.3bn from ¥67.9bn.
Other segments contributed more modestly. Sales in the Materials and Chemicals segment rose 15.4% to ¥2.6bn and operating profit more than doubled to ¥222mn; the company cited higher sales of industrial-material glass fiber alongside price revisions that helped offset rising input costs. The Insulation Materials segment swung to an operating profit of ¥251mn from a ¥50mn loss a year earlier, on sales up 24.2% to ¥4.4bn, while the Medical segment grew profit 66.8% to ¥705mn on steady demand for immune-related and bone-metabolism diagnostic reagents.
Nitto Boseki also completed a five-for-one stock split effective July 1, 2026, reflected in its per-share dividend forecast of ¥28.00 for the year; before the split, the equivalent full-year dividend would have been ¥140.00. The company noted its guidance rests on information and assumptions available now and that actual results may differ.
