With the rapid development of AI technology, surging demand for computing power, and accelerated data center construction, the high-speed optical module and optical device market is experiencing explosive growth. As core passive chips in the optical communications field, the demand for silicon lenses and silicon capacitors is also rising accordingly. Suzhou Suna Optoelectronics Co., Ltd. (hereinafter referred to as "Suna Optoelectronics"), with its leading technical strength and global footprint, is spearheading new trends in the industry.

I. Global Footprint Upgrade: Thailand Factory to Begin Production in Q2 2025

SUNA' Thailand production base has completed construction and is scheduled to officially begin production in the second quarter of 2025. Located in Phra Nakhon Si Ayutthaya Province, Thailand, the facility represents a total investment of RMB 40 million, covers an area of 2,000 square meters, and includes 1,000 square meters of cleanroom space. With this addition, SUNA has formed a global network encompassing a China-based R&D center, a Thailand production base, a Singapore sales company, and service representative offices in Europe and the United States — delivering efficient and secure products and services to customers worldwide.

II. Cumulative Silicon Lens Shipments Exceed 250 Million Units, Capturing Over 60% Global Market Share

The company's silicon lens chips have been widely used in optical modules ranging from 100G to 1.6T and beyond, with cumulative shipments exceeding 250 million units. Holding over 60% of the global optical communications market share, SUNA solidifies its position as the industry's undisputed leader. In addition, the company has also expanded into diffractive optical products (such as gratings, DOEs, etc.), offering customers a more comprehensive optical solutions portfolio.

At the end of 2023, Suna Optoelectronics completed the construction of its 8-inch pilot line, with a cumulative investment of nearly RMB 300 million. As another core product line for the company, silicon capacitor chips deliver excellent performance in high-temperature, high-frequency, high-voltage, and high-reliability applications. They have successfully entered the optical module and consumer electronics markets, securing small-batch orders from leading customers. Looking ahead, silicon capacitors are poised to unlock even greater potential in AI, automotive, specialty applications, and beyond.

IV. Building a Robust "5T" Customer Value Proposition to Empower Customer Success

SUNA consistently adheres to the principle of "customer centricity" as its foremost mission, building a customer value proposition centered on the "5T" core philosophy:
1. fast: 2-day requirement assessment, 7-day standard delivery or 4-week custom delivery, 365/24/7 year-round service.
2. support: Localized teams providing one-stop solutions with no minimum order quantity (MOQ) restrictions.
3. Technology: Over 30% of revenue invested in R&D, holding more than 100 patents, with globally leading technology.
4. trust: Cumulative silicon lens shipments exceeding 250 million units, over 60% global market share, zero quality incidents, and a global footprint ensuring long-term partnership.
5. cosT (Low Cost): Providing the lowest total cost of ownership (TCO).
TCO = 4T (fast + support + Technology + trust) + NRE + BOM
With the first 4T, we create core value for our customers. In addition, we continuously drive cost efficiency and enhance value for customers across both NRE and BOM costs.
