Dear Valued Clients and Partners,

As the Year of the Horse approaches, we would like to take this opportunity to thank you for your continued trust in RJ-BOT Industrial Group's intelligent pipeline and industrial cleaning solutions.

Please be informed that our company will be observing the traditional Chinese Spring Festival holiday to allow our team to celebrate with their families.

Our holiday schedule is as follows:

• Holiday Period: February 12th, 2026 (Thursday) to February 25th, 2026 (Wednesday).

• Resumption of Operations: We will return to normal business hours on February 26th, 2026 (Thursday).

During this holiday period, inquiries regarding our products—from our S6 Tank Cleaning Robots and Grease Duct solutions to our Sewer Inspection systems—may experience delayed responses. Manufacturing and shipping will also be temporarily paused.

Just as our robots need recharging after a tough job, our dedicated team is taking this time to recharge for the year ahead. We appreciate your understanding and patience. We look forward to gearing up and continuing to provide you with cutting-edge cleaning automation when we return.

Wishing you a prosperous, happy, and healthy Chinese New Year!

Sincerely,

The RJ-BOT Industrial Group Team
