II. The Main Questions Raised by Investors at This Meeting and the Company’s Responses

At this briefing, the Company provided answers to the issues of concern to investors. The main questions and responses are summarized as follows:

Question 1: Mr. Ye, hello! Why did the company incur losses last year’s performance? How many orders does the company currently have in hand? How will the company achieve turnaround to profitability this year?

Response: Hello, and thank you for your attention! The net profit attributable to shareholders of the listed company decreased compared with the same period last year, mainly for the following reasons: First, the gross margin of products declined. Due to the year-on-year increase in procurement costs of upstream core raw materials and electromechanical components, together with intensified industry market competition, the product profit margins were subject to certain compression. The Company has actively taken measures to reduce costs and increase efficiency—such as process optimization, technological innovation, and refined cost management—to improve its overall profitability. Second, sales and R&D investment continued to increase. The Company aligns with industry development trends and continues to advance multi-channel market expansion and customer development in the data center field, increasing efforts in market promotion, brand building, and customer outreach; the cultivation of relevant markets has a certain cycle, and the current period’s investment has not fully converted into order revenue. At the same time, the Company increased its R&D layout in innovative areas such as high-efficiency thermal management technologies and energy-saving heat dissipation systems, resulting in a corresponding increase in R&D expenses. Third, the infrastructure projects are in a phased cultivation period. In the楷德悠云 data center project, certain assets have reached usable status and have been transferred to fixed assets; preliminary operating expenses have already occurred, leading to phased losses for the project. In the future, as customers gradually move in and the project is formally put into operation, the Company’s operating performance will improve effectively. As of December 31, 2025, the amount of orders the Company has on hand is 94,730.92 million yuan. The Company will do its utmost to improve performance and protect the interests of investors. Thank you!

Question 2: 1、Hello, leaders. The Jialituo Convertible Bond is due this July. Currently, there are only a little over 3 months left until maturity, which makes it a near-maturity instrument. What does the Company hope for with this amount of funds: to convert into shares to continue supporting the Company’s development, or to redeem the principal and pay interest and dividends at maturity? If the Company has a strong redemption intention, given that the conversion value is currently low, what plans does the Company have to facilitate conversion? 2、How does the Company view the current stock price performance? Where are the performance growth drivers in the first quarter and the semi-annual report this year? In the remaining only 3+ months, does the Company have confidence to have the stock price rise above the strong redemption line through performance release or capital operations, thereby protecting the interests of the vast number of convertible bond investors? 3、If conversion is not possible at maturity, is there any way to repay all principal and pay interest and dividends in full on time?

Response: Hello, and thank you for your attention! Based on the Company’s current stock price and the outstanding balance of the convertible bonds, the Jialituo Convertible Bond has not yet triggered the strong redemption clauses in the offering memorandum. In the future, if relevant clauses are triggered, the Company will strictly comply with the requirements of applicable laws and regulations, carry out decision-making procedures and fulfill information disclosure obligations, and serve all shareholders and convertible bond holders well. The stock price in the secondary market is influenced comprehensively by multiple factors, including the macroeconomic environment, industry cycles, and market liquidity. The Company’s production and operations are normal, and it has sufficient cash flow. If the Company’s convertible bonds trigger redemption clauses, the Company has strong repayment capability. The Company currently carries out cost reduction and efficiency improvement activities on a regular basis, continuously strengthens cost management and control, keeps enhancing market expansion efforts across its business segments, strengthens the Company’s operating management, continuously increases R&D investment, keeps promoting technological innovation, enhances the Company’s core competitiveness, and promotes sound and high-quality development, so as to give back to investors to the greatest extent possible. Thank you!

Question 3: Hello, leaders. 1、The Jialituo Convertible Bond will mature this July. Currently, there are only about 3 months left until maturity. What does the Company hope for with this amount of funds: to convert into shares to continue supporting the Company’s development, or to redeem the principal and pay interest and dividends at maturity? If the Company has a strong redemption intention, what plans does the Company still have at the last moment to facilitate conversion? 2、How does the Company view the current stock price performance? Where are the performance growth drivers in the first quarter and the semi-annual report this year? In the remaining only 3+ months, does the Company have confidence to have the stock price rise above the strong redemption line through performance release or capital operations, thereby protecting the interests of the vast number of convertible bond investors? 3、If it is only possible to repay money at maturity, can the Company repay the principal and pay interest and dividends on schedule?

Response: Hello, and thank you for your attention! Based on the Company’s current stock price and the outstanding balance of the convertible bonds, the Jialituo Convertible Bond has not yet triggered the strong redemption clauses in the offering memorandum. In the future, if relevant clauses are triggered, the Company will strictly comply with the requirements of applicable laws and regulations, carry out decision-making procedures and fulfill information disclosure obligations, and serve all shareholders and convertible bond holders well. The stock price in the secondary market is influenced comprehensively by multiple factors, including the macroeconomic environment, industry cycles, and market liquidity. The Company’s production and operations are normal, and it has sufficient cash flow. If the Company’s convertible bonds trigger redemption clauses, the Company has strong repayment capability. The Company currently carries out cost reduction and efficiency improvement activities on a regular basis, continuously strengthens cost management and control, keeps enhancing market expansion efforts across its business segments, strengthens the Company’s operating management, continuously increases R&D investment, keeps promoting technological innovation, enhances the Company’s core competitiveness, and promotes sound and high-quality development, so as to give back to investors to the greatest extent possible. Thank you!

Question 4: Hello, leaders! How is the Company’s latest liquid cooling product technology?

Response: Hello, and thank you for your attention! The Company has been exploring from air-flow and liquid-flow coordination to extreme-limiting cooling. Product matrices such as prefabricated liquid cooling solutions provide tailored temperature control solutions for high-heat-density scenarios. The new generation rCooling series in-row variable-frequency fluorine pump air conditioners, with single-unit cooling capacity exceeding 70kW, enable unrestricted single-unit rack power density; the containerized liquid cooling solution—“ready to use upon delivery”—enables efficient and convenient deployment of green computing power. Meanwhile, relying on its deep technical accumulation and large-scale production capabilities, the Company focuses deeply on the R&D and manufacturing of test equipment specifically for liquid cooling testing environments, providing the industry with an end-to-end testing infrastructure solution from core equipment to complete system solutions. The Company has achieved mature design and mass production capabilities for 2MW-class CDUs. The Company’s 2MW rack-mount CDU provided for a certain project is a high-difficulty, room-level product designed specifically domestically for performance testing of high-density liquid-cooling complete rack units supporting ultra-large-scale intelligent computing clusters; its heat exchange capacity reaches the 2MW class. Thank you!

Question 5: How is the progress of the funds raised in the Company’s initial public offering?

Response: Hello, and thank you for your attention! The Company’s raised capital investment projects, namely the “Research and Development Project for an Integrated Smart Building Environment Solution (RDS)” and the “Construction Project for an Annual Production of 3,900 Precision Air Conditioners and 150 Magnetic Suspension Chilled-Water Chiller Units,” are expansion and R&D projects in the Company’s main business of data hall environment control implemented on the same plot of land. Based on the Company’s production capacity needs and according to the principle of giving priority to what is more urgent over what is less urgent, the expansion project has progressed relatively quickly. Currently, the “Construction Project for an Annual Production of 3,900 Precision Air Conditioners and 150 Magnetic Suspension Chilled-Water Chiller Units” has basically completed the investment, and the construction investment for the “Research and Development Project for an Integrated Smart Building Environment Solution (RDS)” has also basically been completed; some investments related to R&D equipment, software, and R&D expenses remain to be paid. In light of the construction period of the Company’s raised capital investment projects, the Company plans to extend the implementation period for the “Research and Development Project for an Integrated Smart Building Environment Solution (RDS)” until June 30, 2026 to reach the scheduled usable status. Thank you!

Question 6: Leaders, do you have any countermeasures or plans for improving the gross margin?

Response: Hello, and thank you for your attention! Gross margin is affected by the year-on-year increase in procurement costs of upstream core raw materials and electromechanical components, and the added pressure from intensified industry market competition, which compresses product profitability to a certain extent. At present, the Company has actively taken measures to reduce costs and increase efficiency—such as process optimization, technological innovation, and refined cost management and control—to improve overall profitability. Thank you!

Question 7: Leaders, when will the data center projects Phase II and Phase III be completed approximately? Will they be delayed again afterwards?

Response: Hello, and thank you for your attention! The Company has established a sound system for the management of raised funds and uses raised funds prudently. Although the projects of this round of raised funds have undergone sufficient feasibility demonstration, during actual implementation they have been affected by various factors such as the market environment. For the楷德悠云 data center project (Phases II and III), the main structural construction has basically been completed. The work now involves installing building water and electricity, fire protection systems, outdoor roads, and landscape projects. After the above building works are completed, electromechanical equipment installation will be carried out. The楷德悠云 data center project is planned to be implemented in three phases. The rack units for Phase III will be ramped up onto the site progressively over three years. The Phase I project actually reached the scheduled usable status in December 2024, and the overall progress of the project has been delayed compared with expectations. To cope with market risks, the Company, adhering to the principle of steadily advancing project implementation, and in combination with market demand, appropriately controls the project investment pace. It mitigates market disposal risks by gradually ramping up the racks. After careful research, the Company decided to extend the implementation period of the楷德悠云 data center project (Phases II and III). The Company plans to extend the implementation period of the non-public offering stock raised funds investment project “Nanjing楷德悠云 data center project (Phases II and III)” that was intended to reach the scheduled usable status from March 31, 2025 to June 30, 2026. The Company will disclose specific progress in a timely manner in accordance with relevant laws and regulations. Thank you!
