Shares of SU Group Holdings rose approximately 19% during trading on September 15, 2026, after the company announced exclusive rights to distribute HDX’s TRACELINE PX3 Portable X-Ray System in Hong Kong and Macau and agreed to acquire KM Safety Solution Company Limited for HK$5.62 million in cash. The HDX arrangement is SU Group’s second global distribution deal in 2026, following its June partnership with Germany’s GEZE. The proposed KM Safety purchase remains subject to satisfactory due diligence and regulatory clearances and must close by October 31, 2026. TRACELINE PX3 is designed for explosive ordnance disposal, fire investigations, technical surveillance countermeasures and industrial non-destructive testing, using pulsed X-ray technology that reportedly cuts radiation exposure by more than 70% compared with continuous-source systems.
