The reasons the company gives
The company's own explanation, not something inferred from the numbers.Performance remained sluggish for the 3 years through the fiscal year ending March 2026, and the business scale contracted as the gemstone business failed to grow as planned. Meanwhile, diamond device development has become more active worldwide, and prospects have emerged for developing large single crystals into wafer products for device fabrication.
