Price Adjustment Notice — March 2026

PRICE ADJUSTMENT NOTICE

Dear Valued Customer,

Thank you for your continued trust and support in our company.

Recently, due to fluctuations in global commodity prices and the continuous rise in supply chain costs, the procurement prices of our major raw materials — including aluminum foil, glass fiber, and chemical products — have increased significantly, resulting in a substantial rise in production costs. To ensure product quality and service standards, and to maintain long-term stable cooperation between both parties, our company has carefully decided to implement a comprehensive price adjustment across all product lines effective March 9, 2026.

The specific adjusted prices will be based on the latest official quotations provided by our respective sales managers. For orders with signed contracts and locked-in pricing, we will strictly adhere to the contractual terms to ensure that your interests remain unaffected.

We remain committed to delivering high-quality products and excellent services to reciprocate your trust and support. Should you have any questions, please feel free to contact your designated sales manager at any time.

With best regards,

Ming Yang Glass Fiber Co., Ltd.
