Rigaku Holdings surges on publication of group research in leading journal

Tue Jun 9, 2026 10:45 am JST Catalyst

Rigaku Holdings <268A> shares surged on Tuesday. The firm announced Tuesday that research results from a joint study involving its subsidiary Rigaku, Shionogi & Co.,Ltd. <4507>, JEOL Ltd. <6951>, and Meiji Pharmaceutical University were published in Crystal Growth & Design, a prominent international crystallography journal. The news fueled the rally.

The study identified a new polymorphic form of indomethacin, a widely used analgesic and anti-inflammatory drug, completing its structural analysis and property evaluation. While indomethacin has been studied for decades, discovering a new polymorphic form is extremely rare, and Rigaku Holdings noted that the achievement holds significant weight for both crystallography and pharmaceutical research.
