The Board of Directors of the Company and all members of the Board warrant that there are no false representations, misleading statements or material omissions contained in this announcement and accept full responsibility for the authenticity, accuracy and completeness of the information contained herein.

In order to thoroughly implement the spirit of the 20th National Congress of the Communist Party of China, the Third Plenary Session of the 20th CPC Central Committee and the Central Financial Work Conference, diligently implement the requirements of the Several Opinions of the State Council on Strengthening Regulation, Forestalling Risks and Promoting the High-Quality Development of the Capital Market and actively respond to the Shanghai Stock Exchange's (the “SSE”) Initiative on Launching the Special Action of "Improving Quality and Efficiency and Focusing on Return" for SSE Listed Companies , Acter Technology Integration Group Co., Ltd. (the “Company”) has formulated the 2025 Action Plan for “Improving Quality and Efficiency and Focusing on Return” to deeply practice the “investor-oriented” philosophy, further promote the Company to achieve high-quality development, continuously enhance its core competitiveness and enterprise value, increase investor returns, and protect the legitimate interests of investors, especially small and middle-sized investors. Details of the Plan are as follows:

I. Enhancing Operational Quality

(I) Focusing on the Company's Core Business and Continuously Enhancing Core Competitiveness

Against the backdrop of accelerating global artificial intelligence technology iterations, international semiconductor giants and cloud service providers continue to increase capital expenditure, strategically advancing the research and development of advanced processes, driving the accelerated iteration of AI chips, HBM memory chips, and COWOS advanced packaging technologies. This wave of technological innovation is driving the coordinated development of the entire semiconductor industry chain—from upstream large-sized silicon wafers and specialized semiconductor material preparation, to breakthroughs in core process equipment and advanced packaging and testing technologies, and even downstream SMT precision assembly links, with growing demand trends in various segments. With continuous technological advancements, the upgrading of existing industries has driven the upgrading and expansion of manufacturing facilities to meet production demands, providing strong opportunities for the Company to expand its business order scale.

In line with industry development trends, national policy initiatives, business development planning, and continuous improvements in corporate governance, in 2025, the Company will continue to focus on its core business and continuously optimize its engineering technical capabilities. The Company will implement a development strategy of "multiple customers, multiple industries, multiple work types, and multiple regions," establish a comprehensive marketing service system, provide customers with more efficient energy-saving and environmentally friendly solutions, and assist them in achieving green transformation and sustainable development.

(II) Standardizing the Use of Proceeds and Continuously Advancing the Implementation of Proceeds-funded Projects

In 2025, the Company will continue to strictly manage proceeds in accordance with the regulations of the China Securities Regulatory Commission, the SSE regarding the use of proceeds, and the Company's Measures for the Management of Proceeds , and will disclose the deposit and actual use of proceeds in a timely, truthful, and accurate manner.

The Company will continuously advance the construction and implementation of

proceeds-funded projects, strictly comply with the Measures for the Management of Proceeds , strengthen supervision over the use of proceeds, ensure the legal and effective use of proceeds, promote the development of the Company's main business through the implementation of proceeds-funded projects, achieve the expected returns of proceeds-funded projects, and enhance the Company's overall profitability.

II. Accelerating the Development of New Quality Productive Forces

Under the dual drivers of industrial upgrading and green construction, professional cleanroom system integration engineering enterprises are achieving rapid deployment of clean environments and energy efficiency optimization through full-chain technology integration capabilities, deeply integrating prefabricated construction technologies with modular engineering systems, with standardized design, industrial prefabrication, and intelligent operation and maintenance as the core. This provides high-performance, low-energy-consumption, and iterative sustainable solutions for high-tech fields such as semiconductors and biopharmaceuticals.

Based on current industry development trends, in 2025, the Company will further strengthen the application of BIM technology for prefabricated "modular" design, manufacturing, and installation integration methods. By changing traditional work sequences and effectively allocating and combining various specialties and processes, modules prefabricated in processing plants will be transported to project sites for assembly, enabling more effective clean control, rapid completion of cleanroom system integration, improved operational efficiency, and shortened construction periods, thereby promoting the Company's high-quality development and leading industrial transformation and upgrading.

Talent is the core competitiveness of the Company's development. In 2025, the Company will continue to optimize its talent incentive mechanism and maintain the stability of its R&D team. The Company will further establish industry-university-research cooperation relationships with universities and research institutions to jointly carry out scientific research projects, internships, and talent cultivation programs, reserve high-quality professional talents for the Company, enhance the Company's technological innovation capabilities and R&D level, and lay a solid foundation for the Company's long-term development.

III. Improving Corporate Governance

A sound corporate governance structure and profound corporate culture are the cornerstones of stable enterprise development. We will further improve the corporate governance mechanism, optimize the organizational structure, strengthen internal management, while continuously deepening corporate culture construction, promoting core values, and creating a positive working atmosphere, making the Company a team with strong cohesion and centripetal force to achieve sustainable development. The Company has formulated more than 30 systems including public opinion management, accountant selection, and market value management, and has set up an internal audit department to audit the implementation of various systems to ensure the orderly execution of each link of internal control.

In 2025, the Company will promptly track the latest developments in laws and regulations, continuously revise and improve relevant internal systems in combination with the Company's actual situation and development needs, vigorously promote the implementation of various systems, and continuously optimize the Company's internal governance system, so as to ensure that the operations of the Shareholders' General Meeting, the Board of Directors, and the Board of Supervisors are strictly executed according to relevant specified procedures, to guarantee the performance of independent directors through providing convenient conditions for them, and to establish a good internal control environment.

IV. Strengthening the Responsibility of "Key Minority"

In 2025, the Company will continue to strengthen the training of "key minority personnel" such as directors, supervisors, and senior management. By leveraging regulatory platform resources including the China Securities Regulatory Commission, the SSE, the Shanghai Stock Exchange Academy, the China Association for Public Companies, and the China Capital Market Institute, the Company will urge its directors, supervisors, and senior management to actively participate in training and learn about duty performance courses, policy essentials, and new regulations. This will ensure that the management team can learn and master the latest legal and regulatory knowledge, understand regulatory dynamics, continuously strengthen compliance awareness, and lead the enterprise toward sustained and stable development. Simultaneously, the Company

will further optimize the incentive and constraint mechanisms for the management team, reasonably linking senior executive compensation with the operating performance of the listed company, with compensation changes generally matching the Company's operating results, promoting the deep integration of interests between the management team and shareholders.

V. Enhancing Investor Returns

The Company has always firmly established the awareness of returning value to shareholders, closely monitoring market evaluations of the Company's value, and actively enhancing its ability and level of investor returns. The Company implements the Several Opinions of the State Council on Strengthening Regulation, Forestalling Risks and Promoting the High-Quality Development of the Capital Market , further enhancing the stability, continuity, and predictability of cash dividends, increasing the frequency of cash dividends, and strengthening investor satisfaction. The Company's Board of Directors requests the Shareholders’ General Meeting to authorize the Board to decide on interim dividend matters for 2025. The Company will, upon comprehensive consideration of the Company's profitability, cash flow situation, and future development plans, seek the optimal balance between operational development, performance growth, and shareholder returns, and provide shareholders with competitive dividend returns.

The Company will strengthen daily public opinion monitoring and analysis, closely monitor various media reports, and promptly respond through clarification announcements and other means when detecting market rumors that may significantly impact investor decisions or the Company's stock trading, fully protecting the interests of all shareholders.

VI. Strengthening Investor Communication

（1） In 2025, the Company plans to hold at least 3 performance briefings (annual report, semi-annual report, third quarter report), combining various formats such as live broadcasts, recorded broadcasts, and text interactions. Through video and text live broadcasts, graphic demonstrations, bilingual periodic reports and ESG reports, the Company will visualize complex financial data and operational conditions, building an equal platform for domestic and foreign investors to understand the Company.

（2） The Company has designated personnel to monitor the SSE e-interaction platform, email, and investor hotline in real-time, providing timely and targeted answers to questions of concern to investors. The Company will compile research records from various investor communications and disclose them after the market closes on the last trading day of each month to ensure the right to know for the broad investor base. For questions on the SSE E-interaction platform, the Company ensures responses within 2 trading days to the extent permitted by applicable information disclosure regulations.

（3） In 2025, while continuing to disclose periodic reports and temporary announcements in a truthful, accurate, and complete manner, the Company will increasingly attempt to use graphics and charts to illustrate points, highlight key information, and reduce the reading burden on investors. By adding an "IR Interaction" (“投关互动”) section to the existing Company's WeChat public account, synchronizing information from Investor Info column of the Company's official website to the WeChat public account, and releasing information such as the Company's daily operations from time to time, the Company will deliver information to investors through more dimensions and provide faster, more convenient, and diversified communication channels.

（4） The Secretary of the Board of Directors' Office is specifically responsible for investor relations management. Team members should fully understand the Company's corporate culture, strategic planning, operational status, business conditions, etc., and possess professional knowledge backgrounds in finance, accounting, law, etc., to respond to investor inquiries promptly and efficiently. The Company will also organize internal training from time to time to enhance team members' understanding and mastery of the Company's business, industry dynamics, and capital market regulations and policies.
