TAICHUNG, Taiwan: ASE Technology Holding Co., Ltd. (ASE Holdings. NYSE:ASX, TAIEX: 3711), today hosted its annual Supplier Day, recognizing the contribution of all its valued partners and to present awards to the outstanding suppliers of 2025. The event welcomed representatives from over 100 suppliers supporting ASE Holdings’ subsidiaries – ASE, SPIL, and USI. Centered on the theme 'Innovation of Synergy,' the ceremony highlighted the role of technology innovation and knowledge sharing in strengthening the competitiveness of industry partners. It also emphasized ASE’s commitment to building a more resilient, collaborative, and future-ready supply chain ecosystem.

“Driven by surging demand for AI and High-Performance Computing (HPC), the global semiconductor industry is projected to exceed US$1 trillion by 2026, reflecting strong structural growth,” said Dr. Tien Wu, Chief Operating Officer of ASE Holdings. “As technology advances and system complexity increases, hardware has evolved into a defining factor in enabling innovation at scale. Looking ahead, applications will extend beyond cloud data centers to the edge, with emerging areas such as drones and robotics expected to drive the next wave of growth. With its comprehensive semiconductor ecosystem, Taiwan is well-positioned to sustain its global leadership while continuing to deepen international collaboration, strengthen supply chain resilience, secure critical technologies, and accelerate system-level optimization."

ASE Holdings is committed to proactively empowering its suppliers to enhance their capabilities and drive long-term sustainable growth. Since 2022, ASE has provided guidance and resources to advance a green, low-carbon supply chain, successfully helping 37 suppliers to establish greenhouse gas inventory systems in line with ISO 14064 and product carbon footprint capabilities aligned with ISO 14067, all verified by independent third parties. To recognize these achievements, ASE presented certificates of appreciation during the ceremony, underscoring its commitment to collaboration and encouraging more partners to embed carbon management into their core business operations.

At this year’s event, three suppliers were honored with the 2025 Supplier Sustainability Award for their innovative collaboration initiatives. Aligned with ASE’s core sustainability priorities – including low-carbon and circular goals – these award-winning projects will receive sponsorship from the ASE Environmental Sustainability Foundation.

"Through this supply chain collaboration program, we aim to guide and support more suppliers in taking proactive sustainability actions, thereby amplifying the industry’s positive impact and creating a shared path toward green growth,” said Dtuang Wang, CAO and CSO of ASE Holdings.

Adding weight to the event’s proceedings was the invited guest of honor; Eliza Li, Chairman of PwC Sustainability Services Company who remarked, “Uncertainty has become the new normal in today's business environment. Structural changes, driven by technological disruption, geopolitics, climate change, and regulatory/resource constraints, are constantly testing corporate adaptability. Collaborating with partners on sustainability and innovation is the only way to enhance resilience and capture new opportunities in both technology and sustainable development.”

“The semiconductor supply chain is entering a new phase marked by increasing consolidation and rising technical standards driven by industry leaders. We are seeing heightened supply-demand volatility, extended lead times, and an accelerated pace of technology advancement,” said Andrew Tang, Chief Procurement Officer, ASE Holdings. “These shifts represent the ongoing reallocation of capital, capacity, and resources across the supply chain to meet strong market demand and rapid technology breakthroughs. While this environment presents significant opportunities for the semiconductor industry, it also introduces new risks and complexities. Looking ahead, ASE believes that supply chains with scale, agility, and deep ecosystem synergy will be best positioned to manage risk and capture growth.”

As an industry leader, ASE will continue to collaborate closely with its partners to streamline processes, enhance visibility and transparency, and build deeper mutual trust. The company looks forward to working with its suppliers to strengthen its position in this dynamic market, achieving shared prosperity and mutual success.
