**Semilux International Ltd. Secures Taiwan Coast Guard UAV Pilot Program**

On December 31, 2025, the Taiwan subsidiary of SemiLux International Ltd. (the "Company"), Taiwan Color Optics, Inc. ("TCO"), was awarded the Coastal and Maritime Surveillance UAV Pilot Program by the Taiwan Coast Guard Administration, under the Ocean Affairs Council of Taiwan. The contract value of the pilot program is approximately $7 million.

This pilot program represents a milestone in Taiwan's deployment of long-endurance, long-range unmanned aerial systems for maritime surveillance and law-enforcement missions.

According to the official award announcement dated December 30, 2025, the procurement attracted four qualified bidders. TCO was ranked first in the evaluation and selected as the best-value bidder, based on systems integration capability, operational readiness, and lifecycle support planning.

The award reflects the Taiwan government's recognition of the Company's strengths in advanced optical sensing, UAV system integration, and localized production and sustainment. The core system of the pilot program is based on cooperation between the Company and Edge Autonomy, a U.S. manufacturer of unmanned systems. In this program, TCO will be responsible for overall systems integration, localized manufacturing activities, and ongoing technical support in Taiwan.

**Outlook**

Following the current pilot program, Taiwan's Coast Guard Administration and Ministry of National Defense of Taiwan have publicly outlined follow-on UAV requirements as part of a coordinated national approach to maritime security and defense resilience, with the Taiwan Coast Guard pursuing a medium-range UAV expansion program and the Ministry of National Defense pursuing a large-scale fixed-wing VTOL UAV program. Building on the experience gained from the current Coast Guard pilot program, the Company believes that it is well positioned to support coast-guard and defense-scale UAV programs through proven long-endurance platforms, advanced optical and AI-enabled sensing integration, localized manufacturing and training capacity, and Blue UAS–aligned system architecture. Leveraging the Company as the international holding and capital platform, and TCO as the core execution and manufacturing arm, the Company aims to contribute to resilient and trusted defense and security supply chains across the Asia-Pacific region.
