Dadongnan: Overall installation and commissioning milestone for two production lines

Securities Star News: On April 2, Da Dongnan (002263) replied to questions of concern to investors on the investor relations platform.

**Investor: **Hello, Secretary of the Board. Based on your reply that “of the two imported magnetron coating production lines in Ningbo Vientiane, one has already been delivered to the company, and the other is expected to arrive at the plant in May; the installation, commissioning, and completion of both production lines are planned to be fully finished by June this year.” It can be inferred that for each set of new equipment, from installation and commissioning to reaching production, can be completed within 1 month. Since one set of new equipment has already arrived at the plant, this equipment could be completed for installation and commissioning and reach production in mid-to-late April; that is, the two production lines will be installed and commissioned in sequence and then reach production one after the other. Please respond! [Your company’s work efficiency really leaves many shareholders speechless and definitely needs to be improved.]

**Da Dongnan Secretary of the Board: **Hello. Regarding the installation, commissioning, and production reach timeline for the two imported magnetron coating production lines in Ningbo Vientiane, what is referred to here is the target milestone for the overall installation and commissioning work for the two production lines, not that it only takes 1 month for a single production line from arrival at the plant to reaching production. Installation and commissioning of a production line is a systematic project involving multiple steps, including equipment positioning, connection, software debugging, optimization of process parameters, trial operation, and more. In addition, the installation and commissioning work for the two production lines will be advanced in an orderly manner and proceed in parallel or in an overlapping way according to the actual situation, to ensure the overall schedule and the quality of final production launch. Therefore, the specific production-reaching time for a single production line needs to be comprehensively judged based on the actual installation and commissioning progress. Thank you for your attention!

**Investor: **Dear Secretary of the Board: Hello! Could you please let me know the number of shareholders of the company as of March 31? Thank you!

**Da Dongnan Secretary of the Board: **Hello. According to the data provided by China Securities Depository and Clearing Co., Ltd., as of March 31, 2026, the number of shareholders of the company is 146001 households. Thank you for your attention!
