HONG KONG, May 20, 2026 /PRNewswire/ -- SU Group Holdings Limited (Nasdaq: SUGP) ("SU Group" or the "Company"), an integrated security-related engineering services company in Hong Kong, today announced the Company won a new government contract for the Hong Kong Civil Aviation Department (CAD), as the government mandates market focus on using artificial intelligence (AI) and Internet of Things (IoT) technologies to improve workplace safety and operational efficiency.

The Hong Kong Government continues to accelerate the adoption of AI- and IoT-enabled Smart Site Safety Systems ("4S") to strengthen safety management and improve performance across public works projects. Since July 1, 2024, 4S has been mandatory for Hong Kong public works contracts, creating a clear compliance-driven market opportunity. The mandate reflects a simple but urgent need: many recent construction accidents, particularly serious incidents, may have been preventable if workers and site personnel had received timely safety alerts.

4S systems are designed to leverage a network of IoT sensors placed throughout work sites to continuously monitor a variety of important areas including structural stability, environmental conditions, and worker movements. This can help improve the site safety performance through early identification of potentially dangerous incidents or dangers and taking immediate follow-up mitigation actions. By combining real-time sensor data with AI-driven analysis, 4S can identify hazards earlier, alert site personnel faster, and support immediate mitigation actions before risks escalate into accidents.

SU Group's Chairman and CEO, Dave Chan, commented, "We applaud the Hong Kong Government for taking a leadership role in advancing AI- and IoT-enabled safety solutions through the implementation of 4S. The opportunity is significant, as virtually every work site faces safety risks, and too many accidents and fatalities remain preventable. Under our latest win, we installed the 4S system for 4 Hong Kong Civil Aviation Department's construction sites of their Navigation Stations, which are used for air traffic control and related engineering services to ensure smooth and reliable operation.  Our continued development of 4S opportunities builds directly on our long track record of providing industry-leading security solutions, positioning us to help customers create safer, more efficient work environments while expanding our addressable revenue base."

SU Group's 4S system integrates AI and IoT to provide:

• Safety Monitoring System using AI to detect any non-compliance through sensors and AI-based cameras;
• Centralized Management using a real-time dashboard showing the safety related index and live videos;
• Digitized Tracking System tracking site plants, power tools and more on a real-time basis through a mobile network;
• Digitalized Permit-to-Work System for High Risk Activities combining security checks, site and weather condition display, labor records and more;
• Hazardous Areas Access Control by Electronic Lock and Key System alerting all customer parties whenever non-compliance detected;
• Tailored Real-Time Alerts for unsafe acts or dangerous situations for mobile plant operation danger zones, with vehicle anti-collision alerts using RFID;
• Non-Compliance Alerts when unsafe acts or dangerous situations are detected in specified zones;
• Smart Monitoring Devices for workers and frontline site personnel to provide real time monitoring;
• Confined Spaces Monitoring System providing real time monitoring of O₂, CO, CO₂, H₂S, CH₄, temperature, PM2.5 levels and more;
• Enhanced Safety Training both onsite and remote using virtual reality headsets.
