The Board of Productive Technologies Company Limited announced that since 1 April 2023, the Company has received purchase orders and evaluation agreements from diverse customers for 106 sets of equipment, an increase of 23 sets from the number disclosed in the announcement of the Company dated 17 January 2024, including cleaning equipment applied to semiconductor wafer manufacturing, wet processing equipment applied to solar cell manufacturing, and copper electroplating equipment applied to solar cell manufacturing (the ``Products''). The revenue from these purchase orders and evaluation agreements is partially recognized. To the best of the Directors' knowledge, information, and belief, having made all reasonable inquiries, the customers and their ultimate beneficial owners are third parties independent of the Company and its connected persons as of the date of this announcement.

The Products are (i) single-wafer cleaning equipment designed for applications in silicon wafer cleaning that removes any adhering particles and organic/inorganic impurities; (ii) solar cell wet processing equipment designed for applications in wafer surface texturing process that reduces reflection losses of the incident light; and (iii) solar cell copper electroplating equipment, which, based on the principle of electrolysis, adopts electrodeposition to coat one particular metal in a layer of metals or alloys, achieving electrode molding for solar cells. Single-wafer cleaning equipment is the core manufacturing equipment with flexible chamber configuration, providing high production efficiency and low cost of ownership. Solar cell wet processing equipment, which includes batch and inline equipment with high efficiency, stability and production capacity, plays a vital role in solar cell manufacturing.

Solar cell copper electroplating equipment is innovatively designed and developed and is compatible with different metal electroplating methods and diverse battery structure types, providing stable and reliable current supply and distribution during the transmission of electrical energy in a cell, creating an encapsulating process solution for equipment operation, material application, process design, and waste liquid recycling.
