Steadfast Aspiration, Everlasting Commitment

Looking back on the decade-long journey of Samcien Semiconductor, we originated as an incubated enterprise of the Chinese Academy of Sciences and have always focused on breakthroughs in core technologies for advanced electronic materials. We appreciate your company as we witnessed the large-scale commercial application of domestic temporary bonding materials in advanced packaging and power devices. Our products have supported the stable mass production of China's high-end server chips, high-computing chips, radio frequency chips, mobile phone processor chips and silicon-based IGBT chips.

Names change, yet our original aspiration remains unchanged:

✓ Our relentless pursuit of technological innovation

✓ Our unwavering commitment to putting customers first

✓ We keep the entrepreneurial passion alive with sincerity and dedication.

All existing cooperation agreements, service terms and rights shall remain fully valid, and business operations will continue seamlessly.

Strategy Elevated, New Journey Ahead

Leveraging our profound expertise in the foundational technology of temporary bonding materials, we keep expanding our business scope to better meet clients' diversified demands for high-end electronic materials. We now possess the capabilities for R&D and mass production of premium thin-film materials such as solder mask dry films for packaging substrates. We strive to deliver one-stop high-end material solutions covering chips to substrates, and serve clients across the global pan-semiconductor sectors including advanced packaging, packaging substrates, power devices and new displays. We aim to build Samcien New Materials into a world-class platform enterprise for advanced electronic materials.

The name "Samcien Semiconductor" can no longer represent our current development landscape. Thus, we embark on a new chapter under the brand "Samcien New Materials":

• 「**Yun** — derived from the idea of steady progress amid all endeavors, symbolizing a down-to-earth and diligent entrepreneurial spirit.

• 「Zhuo — embodying the aspiration for excellence, it demonstrates our ambition to reach the pinnacle of technology and set benchmarks for quality in the industry.

• Samcien is derived from **Semiconductor Advanced Material**. The suffix *cien* means "one hundred" in Spanish, symbolizing our dedication to crafting perfect advanced semiconductor materials with exquisite craftsmanship and a pursuit of excellence.
