Section III Management Discussion and Analysis
I. Discussion and Analysis of Operating Conditions
In 2023, the Company continues to implement the corporate culture policy of “doing it right the first
time, doing it well every time”, consistently and wholeheartedly providing comprehensive services to every
client, and is committed to becoming a creator of high-quality spaces. Looking back on the past year,
“involution” has become the best summary cliche of the increasingly intense Chinese market competition,
while the foreign market is facing pressure due to the increase in labor cases, leading to a shortage of versatile
and professional talents. Facing the complex Chinese and international business environment, the Company
continuously optimizes internal processes, actively takes risk response measures, focuses on the quarterly
business goals conveyed by the lean meeting, and implements strategic measures with small steps and steady
progress. It diligently organizes various tasks, actively adjusts client and product structures, and lays a good
foundation for stability and improvement of competitiveness in terms of cost, quality, safety, progress, and
environmental protection.
The year of 2023 marks a year in which the Company’s research and development technology achievements are demonstrated. During the reporting period, the Company was honored as a “high-tech
enterprise”. As of the end of 2023, the Company held 61 patents, including 9 invention patents, 52 utility
model patents, and 3 software copyrights.
In 2023, the Company achieved steady growth in its business performance. The annual business goals were met as scheduled, with substantial increases in both revenue and net profit. During the reporting period, the Company achieved operating revenue of RMB 2,009 million, an increase of 23.41% year-on-year, and a net profit of RMB 140 million, an increase of 13.86% year-on-year. The Company’s performance growth was mainly due to increased demand from downstream application clients in the clean room industry, the fruitful results of the Company’s early layout in the Southeast Asia region, continuous development of new clients while maintaining stable relationships with existing high-quality clients, and strengthening service innovation capabilities and overall competitiveness through talent development, skills training, and industry- university-research cooperation. The Company’s management team led all employees in standing up to external pressures, overcoming internal difficulties, and making strenuous efforts to successfully fulfill the main objective tasks. II. Industry in which the Company operated during the reporting period (I) Basic Overview of the Industry The Company is primarily engaged in providing clean room system integration engineering solutions for the advanced manufacturing industry as a professional service provider. According to the classification standards of the “National Economic Industry Classification” and the “Industry Classification Guidelines for Listed Companies” issued by the CSRC, the Company’s clean room engineering service belongs to the sub- category “E49 – Building Installation” within the “E – Construction” industry. From the perspective of the industrial chain, the clean room industry can be divided into upstream supply, midstream construction, and downstream applications. Specifically: - Upstream involves suppliers of building materials, system equipment, and electromechanical equipment, which directly impact the progress and completion of projects. Their prices directly affect the industry’s costs and significantly influence the profits of industry enterprises. - Midstream encompasses the Company’s industry, mainly including engineering survey, engineering design, and engineering construction processes. - Downstream refers to industries that require clean rooms in their production or operation processes, mainly in the fields of integrated circuits (IC), photovoltaics, and display panels. The IC semiconductor industry in the electronics sector is currently the primary downstream industry for clean room engineering, and its development significantly influences the future development of industry enterprises. It drives the demand for clean room engineering services, which are fulfilled by industry enterprises. With the continuous advancement of industrial technology, downstream industries constantly raise their requirements for clean rooms, thereby pushing industry enterprises to continually research and develop new technologies, and apply new construction techniques to adapt to the changing market demand. The Company focuses on the integrated engineering of clean room systems in the advanced manufacturing industry, with the “Engineering, Procurement, Construction, and Operation (EPCO)”. It can provide clean workshop construction planning, design suggestions, equipment configuration, clean room environmental system integration engineering, and maintenance services, belonging to the midstream construction industry of the clean room industry chain.

(II) Development Overview of Clean Room Industry
The development of the clean room industry in China began in the 1960s, drawing on the early technology of the former Soviet Union, mainly used in national defense, aerospace, atomic energy, and
scientific research, and later gradually expanded to the control of environmental conditions in industries such
as precision machinery, non-ferrous metal purification in metallurgical systems, and pulling monocrystalline silicon. The clean room industry in China experienced vigorous development from the 1970s to the 1990s. In 1977, the first high-level biological clean room was established, and since the 1980s, the construction of biological clean rooms has gradually increased, extensively used in the daily chemical industry. Subsequently, clean rooms began to be applied in the pharmaceutical and food industries, especially after the announcement of China’s GMP certification in 1982, leading to a significant increase in the demand for clean room construction in the pharmaceutical industry. The construction of clean rooms for medical facilities such as aseptic operating rooms also rapidly expanded. After the reform and opening up, the introduction of foreign-funded enterprises led to the widespread application of higher-level air cleaning technologies in various fields. From the 1990s to the present, China’s technological level has been developing vigorously. The global transfer of production capacity in precision electronics such as semiconductors and new displays has accelerated towards China, greatly increasing the market demand and technological research and development level of the clean room industry as a result of advances in the research and development of pharmaceuticals and biotechnology. This has effectively driven the rapid development of China’s clean room industry. In order to achieve the strategic goal of “carbon neutrality,” China will reduce carbon emissions through energy substitution, energy conservation, and efficiency improvement. According to data from the National Energy Administration, it is expected that during the “14th Five-Year Plan” period, China’s average annual increase in newly installed photovoltaic capacity will be between 70-90GW. As an important part of the construction of solar cell production plants, the demand for the construction of clean rooms will continue to grow alongside the vigorous development of photovoltaic production lines.
