The green manufacturing model builds a dual value system of environmental benefits and economic benefits through energy cost optimization and resource recycling, and promotes the evolution of the industry toward high efficiency, low carbon, and sustainability.

2. Rehabilitation medicine: protect the health of the whole people and provide inclusive rehabilitation services

(1) Industry introduction

According to the four-in-one medical model of "prevention-health-clinical-rehabilitation" proposed by the World Health Organization (WHO), modern medicine has formed a complete system covering the entire life cycle of health management. Rehabilitation medicine, as the core link of disease prevention and functional reconstruction, integrates multidisciplinary diagnosis and treatment technologies such as physical therapy, exercise therapy, occupational therapy, and speech and swallowing training to provide accurate assessment and systematic intervention of functional disorders for complex diseases such as neurological diseases, bone and joint injuries, cardiopulmonary dysfunction, and mental and psychological abnormalities.

As an important support for rehabilitation diagnosis and treatment services, rehabilitation medical devices cover the four core areas of rehabilitation assessment, training, physical therapy and assistive devices. The industry's cyclical characteristics are not obvious, and the products show the typical characteristics of "small batches and multiple varieties" to adapt to differentiated diagnosis and treatment needs.

(2) Development status

①The market is huge and enterprises are scattered

Currently, my country's rehabilitation medical industry is facing the challenge of imbalance between supply and demand. With the acceleration of population aging, the rising incidence of chronic diseases, and the in-depth implementation of the national health strategy, the demand for rehabilitation medical care continues to expand, covering diversified groups such as elderly patients, chronic disease patients, disabled people, postoperative rehabilitation patients, postpartum rehabilitation patients, and sports injury rehabilitation patients, forming a strong and sustained rigid growth momentum. Although a "tertiary medical rehabilitation system" has been built on the supply side, resource allocation is in an "inverted pyramid" structure, with rehabilitation medical resources excessively concentrated in tertiary general hospitals.

my country's rehabilitation medical device production field presents the characteristics of "small and scattered". As of the end of 2020, there were nearly 5,000 rehabilitation medical device manufacturers in China2. Due to the wide variety of rehabilitation medical equipment, the number of manufacturing companies is large but the scale is small, and the market is highly fragmented. Although some companies have certain independent research and development capabilities and sales networks and have formed a certain scale, the overall market concentration is still at a low level.

②Short-term pressures and long-term opportunities under deepening governance

As the country continues to strengthen its comprehensive management of the medical industry, the rehabilitation medical equipment industry is facing short-term adjustment pressure. In the short term, the demand side shows characteristics such as significantly prolonged procurement decision-making process and postponement of non-essential procurement projects. This, coupled with the adaptive adjustment of the sales model, will have a short-term impact on the industry. But in the long term, strict compliance requirements and market purification mechanisms will effectively promote the transformation of competition models and accelerate the industry's transformation from "relationship-driven" to "quality competition." Small and medium-sized manufacturers that rely on traditional channels to compete are facing pressure from order losses, while advantageous companies have increased their market share by strengthening compliance management systems and optimizing product quality to achieve the effect of "short-term standardization and long-term quality improvement."

Intelligent equipment effectively solves the pain points of high human dependence and low efficiency in traditional rehabilitation by providing accurate diagnosis and personalized treatment plans, and continuously optimizes treatment plans with the help of digital data accumulation, bringing patients a more scientific, efficient, convenient, intelligent and humane rehabilitation experience. Technology iteration and intelligence trends will become important driving forces for the future development of the rehabilitation medical equipment industry.

② Demographic structure changes and health management upgrades are two-wheel drive for industry growth

With the rapid acceleration of the pace of aging society, the elderly group's demand for functional restoration and optimization of life quality has become increasingly prominent. The significant intensification of the trend of younger people with chronic diseases has further broadened the scope of demand for rehabilitation services. At the same time, the significant improvement in residents' awareness of health management and the widespread popularization of the concept of "active health" have deepened the closed loop of full-cycle health management needs from prevention, treatment to rehabilitation. This change has formed a dual growth engine of demographic change and consumption upgrading, injecting strong impetus into the future development of the rehabilitation medical industry.

③ Release of market potential in primary care and family scenarios

The continuous deepening of the hierarchical diagnosis and treatment policy has promoted the sinking of rehabilitation equipment into primary medical institutions, and through the construction of a three-level rehabilitation network system, the space for increased demand for primary rehabilitation services has been released. At the same time, the awakening of residents’ awareness of “active health” and the escalation of health management needs have driven the rapid penetration of rehabilitation equipment in home scenarios. Portable and intelligent rehabilitation equipment has therefore become a new growth point in the market, further expanding the market coverage and development potential of the industry.

3. Brain-computer interface: explore health technology and open up new service areas

(1) Industry introduction

Brain-Computer Interface (BCI) is a technology that realizes the interaction between brain signals and machines by directly connecting the human brain and external devices. Its core lies in decoding neuron activity and converting bioelectrical signals such as brain electrical signals into control instructions or feedback information, thus breaking through the physical limitations of traditional human-computer interaction. Technical paths are mainly divided into two categories: intrusive and non-intrusive: the former has high signal accuracy but comes with higher risks, while the latter has strong security but relatively low signal quality. (2) Development status

In 1924, German psychiatrist Hans Berger first recorded human brain electrical activity ("brain waves") and proposed the idea of decoding it. The first general-purpose computer was born in 1946, laying the technical foundation for digital signal processing and artificial intelligence. In 1969, researcher Eberhard Fetz implemented the first brain-computer interface practice, proving that primates could control instruments based on the activity of a single neuron. Driven by multidisciplinary efforts, the concept of "brain-computer interface" was formally established in 1973, launching academic research. After decades of scientific exploration and technological evolution, brain-computer interfaces have moved from science fiction to reality, and have entered a critical stage of transformation from basic research to industry. 3

(2) Business content introduction

①Development overview

With the deepening of the construction of China's rehabilitation medical system, the company has accurately grasped the evolution of the industry and established a stepped coverage strategy of "tertiary hospitals → secondary hospitals/specialty hospitals → primary medical institutions → high-quality ecology". In the early stages of development, the company used tertiary hospitals as a strategic fulcrum to promote local substitution of rehabilitation medical equipment. With the advantages of product performance stability and clinical effects, it quickly gained recognition from tertiary hospitals. It not only established a technical benchmark in the industry, but also formed a brand recognition of "high-end quality". In response to the guidance of the national hierarchical diagnosis and treatment policy, the market strategy gradually extended to secondary hospitals, specialist hospitals and primary medical institutions, and finally achieved full coverage of the tertiary rehabilitation medical service system.

Currently, the company's business is showing a core development trend of "high-end leadership + grassroots penetration": First, the urban medical side is accelerating its transformation to high-quality services. Urban medical institutions such as tertiary and secondary hospitals and specialist hospitals are undergoing a profound transformation from the infrastructure construction stage of rehabilitation medicine to the high-quality service stage, driven by the dual drive of demand upgrades and technological iterations. The demand for precise and high-end products and services has increased significantly. Secondly, grassroots medical institutions have entered the golden period of infrastructure construction of rehabilitation medicine. Compared with urban medical institutions, the construction of grassroots rehabilitation departments started late, and there is still much room for improvement in market penetration. In the context of the accelerated aging of the population and the deepening of hierarchical diagnosis and treatment policies, primary medical institutions continue to demand for the popularization of rehabilitation equipment, standardization of service processes and standardization of clinical pathways, and the market expansion potential is significant.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

②The core of the "high-end leadership" strategy: focusing on "high quality + refinement" to build differentiated competitiveness

A. Four major technology platforms build the cornerstone of rehabilitation equipment innovation

The cornerstone of high-quality medical services lies in the quality of medical equipment, and the core of equipment quality comes from technological innovation. At present, the company has built a technology research and development platform covering four major fields: electrotherapy, pneumatics, electrics, and acousto-optical thermomagnetic.

The electrotherapy technology platform is based on low/medium/high frequency current stimulation acting on the human body to achieve goals such as analgesia, promoting blood circulation, preventing muscle atrophy and improving neurological function. It is widely used in neurological rehabilitation, pain rehabilitation, orthopedic rehabilitation and mental rehabilitation and other fields. The pneumatic technology platform takes pneumatic drive as the core and uses periodic pressure changes to implement limb circulation therapy and joint mobility training, significantly improving the rehabilitation efficiency and comfort of patients with limited movement after surgery. The electric technology platform relies on motor-driven precision mechanical structures to achieve precise and controllable rehabilitation training and therapeutic movements, and mainly serves sports therapy products in the field of sports medicine. The acousto-optical thermomagnetic technology platform focuses on the research and application of physical factors such as sound therapy, light therapy, heat therapy, and magnetic therapy. All types of technologies have unique value in the field of rehabilitation.

At present, the company has deep technical reserves and a complete product matrix in the fields of electrotherapy, pneumatics, and electrics. In the future, development will focus on two major directions: First, empower product upgrades with new technologies such as brain-computer interfaces and artificial intelligence. For example, the brain-computer interface function is used to transform the rehabilitation process from passive to active and build a "treatment-feedback" closed-loop model; at the same time, AI technology is used to improve the accuracy of rehabilitation assessment, training, and treatment, and to optimize the scientific nature of the patient's full-cycle treatment plan. Second, actively promote the collaborative application of multi-modal physical factors, double the efficacy through the synergy of different physical factors, and provide more efficient solutions for complex rehabilitation scenarios. For example, the company's new product launched in 2025 - the swallowing neuromuscular low-frequency electrical stimulator (LGC-2352D series), as the first tongue pressure assessment device in China, innovatively integrates intelligent tongue pressure collection technology and low-frequency electrical stimulation therapy to achieve a closed-loop management of "assessment-treatment-re-evaluation", effectively improving the diagnosis and treatment level of swallowing dysfunction, and successfully filling the gap in the field of oral swallowing function assessment technology in my country.

In terms of the acousto-optical thermomagnetic technology platform, the company is working hard to develop more new rehabilitation technologies, currently focusing on shock wave technology and magnetic stimulation technology. Shock wave technology utilizes the physical properties of mechanical waves for treatment. It has become an important direction in rehabilitation medicine due to its characteristics of "multi-effect mechanisms, non-invasive reach, and wide range of indications." Shock wave technology is mainly divided into two categories: divergent and focused. In the field of divergent shock wave technology, the company has established significant advantages: the independently developed pneumatic ballistic extracorporeal shock wave therapy device is the first of its kind in China. It is not only the first similar product in China to pass CE certification, but also the first in Asia to be certified by the International Conference on Shock Wave Therapy (ISMST).

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

certified products. In the future, the company will accelerate the development of focused technology on the basis of deepening the research on divergent shock wave technology; at the same time, relying on the integration trend of precision medicine and artificial intelligence, the company will promote the breakthrough of shock wave therapy in the direction of personalized plan customization, intelligent operation and multi-modal combined treatment. Magnetic stimulation technology is also a key investment direction of the company. It has launched transcranial magnetic stimulators, transcranial magnetic navigation robots, pelvic floor magnetic stimulators and other products, and will continue to improve the product system in this field in the future.

B. Build a refined, full-cycle intelligent rehabilitation service matrix

In terms of service content iteration, the company has completed the advancement from single product sales to professional solutions in segmented fields. Specialist solutions have formed a full-process service closed loop from precise assessment to precise rehabilitation training and physical therapy. Its core value lies in promoting the upgrade of the service model from traditional product supply to high value-added value services. Based on the actual needs of different groups of people and different disease scenarios, the company has built a professional solution system covering multiple fields, covering neurological rehabilitation, sports medicine rehabilitation, elderly chronic disease rehabilitation, postoperative rehabilitation, maternal and childbirth rehabilitation, mental rehabilitation and many other directions.

In the future, the development direction of specialist solutions will mainly include the following two points: First, full-cycle service layout. On the one hand, it extends to the front end, extending the timing of rehabilitation intervention to acute stages such as ICU, emergency room, and operating room, shortening the inpatient rehabilitation cycle and improving rehabilitation efficiency through early intervention; on the other hand, it extends to the back end, extending services to home rehabilitation scenarios, building a full-cycle rehabilitation service chain covering the "acute phase - recovery period - maintenance period" to achieve seamless connection inside and outside the hospital. Second, digitalization and intelligence. By promoting the intelligent upgrading of rehabilitation equipment, the transformation from "experience-oriented" to "data-driven" is achieved to facilitate precise rehabilitation; at the same time, relying on the Internet of Things and other technologies to achieve intelligent management of rehabilitation equipment lays the foundation for the construction of a medical alliance and a medical community.

③The core of the "grassroots penetration" strategy: Promote the popularization of professional rehabilitation and open up the "last mile" of rehabilitation

Under the strategic guidance of national policies to drive grassroots rehabilitation development, the company innovatively creates an integrated overall solution of "equipment + technical services" to accurately solve the three core pain points of grassroots institutions' lack of resources, lack of experience, and inefficient operations.

The plan works together through the five major professional systems of "site planning - equipment configuration - operation services - technical support - team building" to provide one-stop support from hardware construction to soft power cultivation for the grassroots: site planning clearly defines functional divisions and manpower allocation standards to build a solid service foundation; the equipment configuration link integrates full-cycle management from selection and procurement to clinical application training to ensure that the equipment is "useful and well-used"; operation services focus on management process optimization to improve institutional operation efficiency; technical support relies on practical

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

Real-time remote guidance and multi-point practice collaboration promote technology sinking; team building strengthens fixed positions and staffing and stepped teaching to build a sustainable talent echelon.

The full-cycle service chain deeply empowers the construction of rehabilitation capabilities at the grassroots level, and combines the intelligent cloud platform to realize the standardization of rehabilitation processes and the digitization of department management, systematically breaking through the bottlenecks of grassroots rehabilitation development, and helping the implementation of graded diagnosis and treatment to achieve results, so that grassroots patients can enjoy standardized and high-quality rehabilitation services at their doorsteps.

(3) Business development planning

Driven by the deepening of policy iterations and the acceleration of industry changes, the company took advantage of the trend and proactively promoted strategic adjustments to its business layout: on the basis of continuing to deepen the business within medical insurance, it accelerated the expansion of the market for rigid needs outside medical insurance, and vigorously promoted the "brand overseas" strategy to form a three-dimensional driven development pattern of "deep cultivation of business within insurance, development of rigid demand outside insurance, and breakthrough in international markets". On this basis, we will use the exploration of cutting-edge technologies such as home care robots as the technical fulcrum to build an innovative growth pole empowered by technology. ① Focus on clinical needs and intensively cultivate the on-guaranteed market

As the company's traditional advantage area, in-hospital business has always been the ballast of performance. Facing the profound changes in the medical industry, the company takes "clinical demand orientation" as its strategic fulcrum and continues to strengthen its in-hospital service moat through technological breakthroughs and model innovation.

At the product development level, we focus on core clinical needs, focus on promoting the research and development and clinical transformation of transcranial magnetic, transcranial electromagnetic, and brain-computer interface series products, create differentiated competition barriers with high value-added innovative products, and break through the homogeneous competition dilemma of traditional medical equipment.

In terms of service scenario expansion, the company continues to extend its focus on sub-specialty clinical integration: taking the rehabilitation department as the basis, under the framework of the DRG/DIP fee control policy, it improves patient treatment effects through early rehabilitation intervention, optimizes the hospitalization cycle, and builds a seamless clinical path of "treatment-rehabilitation"; at the same time, it actively explores new business scenarios in sub-specialties such as mental rehabilitation, and deepens the layout of sub-specialty fields.

② Focus on the rigid demand market and build a second growth curve

Driven by the deepening of medical insurance cost control policies and the upgrading of residents' health consumption, it has become an inevitable trend in the industry to develop the "hard-demand" market, and will form the core engine of the company's second growth curve.

The company actively develops new outpatient rehabilitation scenarios to meet diversified needs: on the one hand, it provides precise services to groups with non-surgical indications and relieves their dysfunction, pain, sports injuries and mental health problems such as insomnia, anxiety, and depression through rehabilitation and other non-drug therapies; on the other hand, it lays out the high-end rehabilitation incremental market and deeply connects with high-end

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

To meet the needs of net-worth people, we focus on expanding high-value channels such as international medical departments and high-end private hospitals, and comprehensively broaden the boundaries of business growth.

At the same time, the company focuses on home health management scenarios and vigorously promotes home rehabilitation business: it continues to iterate the product matrix adapted to home scenarios, builds full-chain online channels, builds a sales system on mainstream e-commerce platforms such as JD.com and Taobao, and relies on the advantages of in-hospital brand reputation to strongly guide out-of-hospital business.

③Promote brands to go overseas and expand global market territory

"Brand overseas" is the key strategy to promote the "Longzhijie" brand to go global. In recent years, the company's global market territory has continued to expand, and its business has gradually expanded from the core markets of Europe and the United States to North America (the United States, Canada, etc.), South America (Brazil, Chile, etc.), Europe (Russia, the United Kingdom, Spain, etc.), Asia (South Korea, Thailand, Turkey, etc.) and other regional markets. In the future, the company will continue to deepen its global layout, consolidate and expand its international influence.

3. Brain-computer interface: explore health technology and open up new service areas

(1) Introduction to business model

The company's brain-computer interface business is led by its holding subsidiary BrainLink Technology, with research and development as its core driving force. It focuses on the independent research and development and technological iteration of high-performance brain-computer interface core hardware and EEG signal decoding algorithms, and continues to improve its technical competitiveness in the entire chain from signal acquisition, processing to analysis.

At the same time, it continues to develop intelligent brain-computer interface products in non-medical fields and expands diverse application directions such as education, elderly care, and health.

In terms of technology and talent reserves, the company relies on its in-depth strategic cooperation with Tsinghua University to open up a full-chain transformation path from laboratory research to industrialization. At the same time, through the construction of an interdisciplinary talent echelon, it integrates superior resources in the fields of computer science, biomedical engineering, electronic science and technology, and forms a full-process, controllable independent research and development system.

(2) Product system introduction and business development planning

According to the arrangement of neural signal acquisition equipment in the human body, brain-computer interface technology paths can be divided into two categories: invasive and non-invasive. The company currently has layouts in both technology paths and has formed their own key directions for different application scenarios.

Non-invasive brain-computer interface technology is mainly realized by collecting scalp EEG signals. With the advantages of non-invasive, safe and low cost, it has become a key direction of the company's current layout. The company focuses on core technology research and development and commercialization, and has built a complete product system with core intellectual property rights. At the hardware level, the independently developed EEG collection equipment covers mainstream technology types such as gel electrodes, saline electrodes, and flexible dry electrodes. The EEG amplifiers launched simultaneously support multi-channel specifications and can be flexibly adapted to medical and consumer application scenarios. At the algorithm level, the company has built an independent technology system covering the entire process of EEG signal processing and decoding, forming core capabilities such as high-precision signal acquisition, real-time decoding optimization, and cross-scenario algorithm adaptation, providing technical guarantee for the stable operation of the system under multi-tasks and multi-environment conditions. At the application level, the company focuses on medical scenarios and actively explores application potential in non-medical fields. The medical field uses neurorehabilitation as a breakthrough to promote the upgrade of traditional musculoskeletal training to an active rehabilitation model of "brain-limb dual pathway activation", and continues to explore new scenarios such as mental illness diagnosis and treatment. In the non-medical field, the application of diversified scenarios such as education, sleep, and elderly care is steadily promoted.

Invasive brain-computer interface technology relies on intracranial EEG signal collection to obtain high-quality, high-resolution neural signals. The company focuses on building an animal experiment platform as a core verification platform for the safety, effectiveness and key technical solutions of self-developed products. It is also open to hospitals, universities and scientific research institutions to build a collaborative innovation platform and industry ecology.

It runs through the entire process of patient management, signal collection, data analysis, and treatment feedback, transforming neural signals from isolated data into long-term data assets that support continuous evaluation and clinical research.

In response to the internal control deficiencies disclosed in the audit report, the company attached great importance to it and established an internal control rectification leading group headed by the chairman of the board at the end of April 2026 to formulate a systematic rectification plan focusing on the three major directions of improving the internal control system, consolidating the financial foundation, and improving compliance management. In order to ensure the objectivity and authority of the rectification work, after review and decision-making by the Audit Committee, the company independently hired Zhongxinghua Accounting Firm as a third-party intermediary agency to assist in the verification and verification of self-examination and rectification. On this basis, the company held a meeting for all middle and senior managers in July to systematically publicize and implement the rectification plan, consolidate rectification responsibilities, and simultaneously carry out regular compliance training and case warning education. The above measures reflect the company's firm determination to face up to problems and resolve risks. The company will continue to make every effort to promote various rectification work and strive to eliminate relevant risk warning matters as soon as possible.

10. Risks faced by the company and countermeasures

(1) The company’s stocks are at risk of delisting

Because the company's 2025 financial statements were issued a "2025 Annual Audit Report" with no opinion expressed by ShineWing Certified Public Accountants (Special General Partnership), and the above triggered the financial mandatory delisting situation stipulated in Article 10.3.1, paragraph 1 (3) of the "Shenzhen Stock Exchange GEM Stock Listing Rules", the company's stocks will be subject to a delisting risk warning by the Shenzhen Stock Exchange.

Based on the situation where the company is issued a disclaimer of opinion audit report and encounters a delisting risk warning, the company will set up a special working group to comprehensively sort out the matters that cause the disclaimer of opinion, formulate rectification plans item by item, and strengthen communication with the annual audit accountant to strive to eliminate the impact of relevant matters as soon as possible. At the same time, the company will further improve internal controls, improve the quality of financial information, actively improve operating conditions, strive to meet the conditions for withdrawing risk warnings, and safeguard the interests of the company and all shareholders.

(2) Risks of intensified market competition

As the strength of the company's downstream industry customers continues to increase, the requirements for products have also increased accordingly, and there are more and more comprehensive demands. In the future, with the development of the domestic and foreign pharmaceutical and biological intelligent manufacturing industries and the rehabilitation medical equipment industry, industry market competition will intensify.

The company will give full play to its brand effect and financing advantages, and use capital market resources to actively respond to changes in the market environment by integrating and optimizing corporate advantages, improving the industrial chain layout, and expanding business sectors. At the same time, it will continue to strengthen independent research and development capabilities, increase product research and development efforts, expand the company's product chain horizontally, develop product performance vertically and in-depth, enhance customer stickiness, increase target customers' attention, trust and satisfaction with the company's products, and enhance the company's core competitive advantages.

(3) Risks of technology research and development and new product development

The company's intelligent manufacturing and rehabilitation medical equipment business are both technology-intensive industries. Product development has the characteristics of long R&D cycle, high technical difficulty, and large capital investment. Therefore, technological innovation and new product R&D play a leading role in whether companies in this industry can continue to achieve a leading position. During the R&D process of new products, the company may have deviations in R&D direction, failure to achieve industrialization of R&D, R&D cost overruns, R&D failures, etc., or competitors may have the same or superior products and technologies, especially some new products and technologies, which will cause the company to face certain risks. If the company fails to recover relevant investment in product development in the future, it may have an adverse impact on the company's financial condition and future development.

To this end, the company has established a research and development risk control system, conducts feasibility studies on research and development projects, and approves projects after management discussions. At the same time, it regularly tracks the project research and development process, provides timely feedback and improves the research and development direction, and reduces the above risks.

(4) Risk of talent shortage

As a technology-intensive industry, high-quality technical talents and management talents play a very important role in the development of enterprises. Especially as the company grows, the company's organizational structure and management system also tend to become more complicated, which puts forward higher requirements for the company's management and control capabilities. Whether it can attract, cultivate, and make good use of high-quality technical talents and management talents is a key factor affecting the company's future development.

In order to cope with risks, the company actively introduces talents, pays attention to talent training, continues to carry out mechanism innovation in talent training and incentives, implements various incentive measures such as employee stock ownership plans, and strives to attract and stabilize high-quality talents.

6. Accounting treatment methods for business combinations under the same control and those not under the same control

(1) Business merger under common control

For a long-term equity investment formed by a business merger under the same control, if the merging party pays cash, transfers non-cash assets or assumes debts as the merger consideration, the share of the book value of the owner's equity of the merged party in the final controlling party's consolidated financial statements on the merger date shall be regarded as the initial investment cost of the long-term equity investment. If the merging party issues equity instruments as the consideration for the merger, the total face value of the shares issued shall be deemed as share capital. The difference between the initial investment cost of a long-term equity investment and the book value of the merger consideration (or the total face value of the shares issued) shall be adjusted to the capital reserve; if the capital reserve is insufficient for offset, the retained earnings shall be adjusted.

(2) Business combination not under common control

For business combinations not under common control, the combination cost is the sum of the fair value of the assets paid by the purchaser, liabilities incurred or assumed, and equity securities issued by the purchaser to obtain control of the purchased party on the purchase date. The identifiable assets, liabilities and contingent liabilities of the acquiree that meet the recognition conditions and are acquired in a business combination not under common control are measured at fair value on the acquisition date. The difference between the purchaser's cost of merger and the fair value of the acquiree's identifiable net assets acquired in the merger is reflected in the value of goodwill. If the purchaser's merger cost is less than the fair value share of the acquiree's identifiable net assets obtained in the merger, and after review, the difference between the merger cost and the fair value share of the acquiree's identifiable net assets obtained in the merger shall be included in the non-operating income of the current period.

7. Judgment standards for control and preparation methods of consolidated financial statements

(1) Judgment criteria for control

The scope of consolidation of consolidated financial statements is determined based on control. An invested unit that possesses the following three elements is deemed to have control over it: having power over the invested unit, enjoying variable returns due to participation in relevant activities of the invested unit, and having the ability to use power over the invested unit to affect the amount of returns. (2) Preparation method of consolidated financial statements

1. Unify the accounting policies of the parent and subsidiary companies, unify the balance sheet dates and accounting periods of the parent and subsidiary companies

If the accounting policies or accounting periods adopted by a subsidiary and the Company are inconsistent, when preparing consolidated financial statements, necessary adjustments will be made to the financial statements of the subsidiary in accordance with the Company's accounting policies or accounting periods.

2. Offset matters in consolidated financial statements

The consolidated financial statements are based on the financial statements of the parent company and subsidiaries, and have eliminated internal transactions between the parent company and its subsidiaries, and between subsidiaries. The share of the subsidiary's owner's equity that does not belong to the company is regarded as minority shareholders' equity and is listed as "minority shareholders' equity" under the shareholders' equity item in the consolidated balance sheet.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

Items are listed. The long-term equity investment held by the subsidiary company in the parent company is regarded as the treasury stock of the parent company. As a reduction of shareholders' equity, it is listed as "less: treasury shares" under the shareholder equity item in the consolidated balance sheet.

3. Accounting treatment of subsidiaries acquired through merger

For subsidiaries acquired through business combinations under common control, the business combination will be deemed to have occurred when the ultimate controlling party began to exercise control, and its assets, liabilities, operating results and cash flows will be included in the consolidated financial statements from the beginning of the current period of merger; for subsidiaries acquired through business combinations not under common control, when preparing consolidated financial statements, their individual financial statements will be adjusted based on the fair value of the identifiable net assets on the acquisition date.

4. Accounting treatment for disposal of subsidiaries

If a long-term equity investment in a subsidiary is partially disposed of without losing control, in the consolidated financial statements, the difference between the disposal price and the share of the subsidiary's net assets continuously calculated from the date of purchase or merger will be adjusted to the capital reserve. If the capital reserve is insufficient for offset, the retained earnings will be adjusted. If control over the investee is lost due to disposal of part of the equity investment or other reasons, when preparing consolidated financial statements, the remaining equity shall be remeasured according to its fair value on the date of loss of control. The difference between the sum of the consideration obtained for disposing of the equity and the fair value of the remaining equity, minus the share of the original subsidiary's net assets calculated continuously from the date of purchase or merger based on the original shareholding ratio, shall be included in the investment income for the period when control is lost, and goodwill shall be offset at the same time. Other comprehensive income related to the equity investment in the original subsidiary will be converted into current investment income when control is lost.

8. Classification of joint arrangements and accounting treatment methods for joint operations

(1) Classification of joint arrangements

Joint arrangements are divided into joint operations and joint ventures. Joint arrangements that are not reached through separate entities are classified as joint operations. An independent entity refers to an entity with a separately identifiable financial structure, including independent legal entities and entities that do not have legal entity qualifications but are recognized by law. Joint arrangements entered into between separate entities are generally classified as joint ventures. If changes in relevant facts and circumstances lead to changes in the rights and obligations of a joint venture party in the joint venture arrangement, the joint venture party will reassess the classification of the joint venture arrangement.

(2) Accounting treatment of joint operations

As a joint operating participant, the company recognizes the following items related to the interest share in the joint operation, and performs accounting treatments in accordance with the relevant accounting standards for enterprises: recognizes assets or liabilities held individually, and recognizes jointly held assets or liabilities based on shares; recognizes income generated from the sale of the share of joint operation output; recognizes income generated by joint operations from the sale of output based on shares; recognizes expenses incurred individually, and recognizes expenses incurred in joint operations based on shares.

The Company is a participant that does not enjoy joint control over the joint operation. If it owns the assets related to the joint operation and assumes the liabilities related to the joint operation, the accounting treatment shall be carried out in accordance with the provisions of the joint operation participants; otherwise, the accounting treatment shall be carried out in accordance with the provisions of the relevant accounting standards for enterprises.

(3) Accounting treatment of joint ventures

The Company is a party to a joint venture and accounts for investments in joint ventures in accordance with the "Accounting Standards for Business Enterprises No. 2 - Long-term Equity Investment"; the Company is a non-joint party and accounts for investments based on the degree of influence on the joint venture.

9. Determination standards for cash and cash equivalents

The cash determined when the company prepares the cash flow statement refers to cash on hand and deposits that can be used for payment at any time. The cash equivalents determined when preparing the cash flow statement refer to investments held with short term, strong liquidity, easy to convert into known amounts of cash, and with little risk of value changes.

10. Foreign currency business and foreign currency statement conversion

(1) Foreign currency business conversion

The Company's foreign currency transactions are recorded in the functional currency using the spot exchange rate on the date of the transaction. Foreign currency monetary items on the balance sheet date are converted at the spot exchange rate on the balance sheet date. The exchange differences arising from the difference between the spot exchange rate on that day and the spot exchange rate on initial recognition or on the previous balance sheet date are included in the current profit and loss, except for the exchange differences on special foreign currency borrowings that meet the capitalization conditions, which are capitalized and included in the cost of related assets during the capitalization period. Foreign currency non-monetary items measured at historical cost are still converted using the spot exchange rate on the date of transaction, and their recording currency amount does not change. Foreign currency non-monetary items measured at fair value are converted using the spot exchange rate on the date when the fair value is determined. The difference between the converted accounting functional currency amount and the original accounting functional currency amount is treated as a change in fair value (including exchange rate changes), and is included in the current profit and loss or recognized as other comprehensive income.

(2) Conversion of foreign currency financial statements

If the Company's subsidiaries, joint ventures, associates, etc. use a different recording currency than the Company, their foreign currency financial statements must be converted before accounting and preparation of consolidated financial statements. The asset and liability items in the balance sheet are translated using the spot exchange rate on the balance sheet date. Owner's equity items, except for the "undistributed profits" items, are translated using the spot exchange rate at the time of occurrence. Income and expense items in the income statement are translated using the approximate exchange rate of the spot exchange rate on the date of transaction. The translation differences of foreign currency financial statements arising from the translation are listed under other comprehensive income in the owner's equity item in the balance sheet. Foreign currency cash flows are translated using an exchange rate determined in a systematic and reasonable manner that is similar to the spot exchange rate on the date when the cash flow occurs. The impact of exchange rate changes on cash is presented separately in the cash flow statement. When an overseas operation is disposed of, the translation difference of foreign currency statements related to the overseas operation shall be transferred to the current profit and loss of the disposal in full or in proportion to the disposal of the overseas operation.

11. Financial instruments

(1) Classification, recognition and measurement of financial instruments

1. Financial assets

Based on the business model of managing financial assets and the contractual cash flow characteristics of financial assets, the Company divides financial assets into the following three categories:

①Financial assets measured at amortized cost. The business model for managing such financial assets is aimed at collecting contractual cash flows, and the contractual cash flow characteristics of such financial assets are consistent with the basic lending arrangement, that is, the cash flows generated on a specific date are only payments of principal and interest based on the outstanding principal amount. Interest income from such financial assets is subsequently recognized in accordance with the effective interest rate method.

② Financial assets measured at fair value with changes included in other comprehensive income. The business model for managing such financial assets aims at both collecting contractual cash flows and selling the financial assets, and the contractual cash flow characteristics of such financial assets are consistent with the basic lending arrangements. This type of financial assets is subsequently measured at fair value, and its changes are included in other comprehensive income, but interest income, impairment losses or gains and exchange gains and losses calculated according to the effective interest rate method are included in the current profit and loss.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

③ Measured at fair value and its changes are included in the current profit and loss. Financial assets held that are not divided into those measured at amortized cost and those measured at fair value and whose changes are included in other comprehensive income are measured at fair value, and the gains or losses (including interest and dividend income) generated are included in the current profit and loss. At initial recognition, a financial asset can be irrevocably designated as a financial asset at fair value through profit or loss if the accounting mismatch can be eliminated or reduced. This designation, once made, cannot be revoked.

For investments in non-trading equity instruments, the Company may irrevocably designate them as financial assets at fair value through other comprehensive income upon initial recognition. This designation is made on an individual investment basis and the underlying investment meets the definition of an equity instrument from the issuer's perspective. This type of financial assets is subsequently measured at fair value. Except for the dividends received (except for the recovery part of investment costs), which are included in the current profit and loss, other related gains and losses are included in other comprehensive income and are not subsequently transferred to the current profit and loss.

2. Financial liabilities

Financial liabilities are classified as: upon initial recognition:

① Financial liabilities measured at fair value with changes included in current profits and losses. Such financial liabilities are subsequently measured at fair value, and the resulting gains or losses are included in the current profits and losses.

② Financial liabilities arising from the transfer of financial assets that do not meet the conditions for derecognition or continued involvement in the transferred financial assets.

③Financial liabilities measured at amortized cost. This type of financial liabilities is measured at amortized cost using the effective interest method.

(2) Recognition method of fair value of financial instruments

For financial instruments with an active market, their fair value is determined based on the quoted prices in the active market; if there is no active market, valuation techniques are used to determine their fair value. In limited circumstances, if there is insufficient recent information to determine fair value, or if there is a wide range of possible estimates of fair value, and the cost represents the best estimate of fair value within that range, the cost may represent an appropriate estimate of fair value within that range. The Company uses all information about the investee's performance and operations that becomes available after the initial recognition date to determine whether the cost represents fair value.

(3) Termination of recognition of financial instruments

If a financial asset meets one of the following conditions, it shall be derecognized: (1) The contractual right to receive cash flows from the financial asset terminates; (2) The financial asset has been transferred and meets the conditions for derecognition.

If the current obligation of a financial liability is discharged in whole or in part, the discharged portion shall be derecognised. If an existing liability is replaced by another financial liability with substantially different terms from the same creditor, or the terms of an existing liability are substantially modified, the existing financial liability will be derecognised and a new financial liability will be recognized at the same time. Buying and selling financial assets in a regular manner will be recognized and derecognized based on transaction date accounting.

12. Notes receivable

13. Accounts receivable

14. Accounts receivable financing

15. Other receivables

Determination method and accounting treatment method of expected credit losses of other receivables

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

16. Contract assets

The Company presents the right to receive consideration for goods or services that have been transferred to the customer (and that right is dependent on factors other than the passage of time) as a contract asset.

The provision for impairment of contract assets refers to the method for determining expected credit losses in the note.

17. Inventory

(1) Classification of inventory

Inventories refer to the finished products or commodities held by the company for sale in daily activities, products in progress during the production process, materials and supplies consumed in the production process or the provision of labor services, etc., mainly including raw materials, low-value consumables, products in progress, self-made semi-finished products, finished products (inventory goods), etc.

(2) Valuation method for issued inventory

When the inventory is shipped, the weighted average method is used to determine the actual cost of the shipment.

(3) Inventory inventory system

The inventory inventory system is a perpetual inventory system.

(4) Amortization method for low-value consumables and packaging materials

Low-value consumables and packaging are amortized using the one-time write-off method.

(5) Recognition standards and accrual methods for inventory depreciation provisions

On the balance sheet date, inventories are measured at the lower of cost and net realizable value, and inventory depreciation provisions are made based on individual inventory items. However, for inventories with large quantities and low unit prices, inventory depreciation provisions are made based on inventory categories. If the factors that previously caused the inventory value to be written down have disappeared, the inventory devaluation provision shall be reversed within the amount originally accrued.

When determining the net realizable value of inventories, it is based on the conclusive evidence obtained and the purpose of holding the inventories and the impact of events after the balance sheet date are also considered. For inventories that are directly used for sale, the net realizable value is determined by the estimated selling price of the inventory minus the estimated sales expenses and related taxes in the normal production and operation process; for inventories that need to be processed, the net realizable value is determined by the estimated selling price of the finished products less the estimated costs to be incurred upon completion, the estimated sales expenses and related taxes during the normal production and operation process.

18. Assets held for sale

19. Debt investment

20. Other debt investments

21. Long-term receivables

22. Long-term equity investment

(1) Determination of initial investment cost

For long-term equity investments obtained through a business merger, if it is a business merger under the same control, the share of the book value of the owner's equity of the merged party in the consolidated financial statements of the ultimate controlling party shall be used as the initial investment cost of the long-term equity investment on the merger date; for business mergers not under the same control, the initial investment cost shall be determined based on the purchase date.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

The merger cost is regarded as the initial investment cost of a long-term equity investment; for a long-term equity investment obtained by paying cash, the initial investment cost is the actual purchase price paid; for a long-term equity investment obtained by issuing equity securities, the initial investment cost is the fair value of the equity securities issued; for a long-term equity investment obtained through debt restructuring, its initial investment cost is determined in accordance with the relevant provisions of the Debt Reorganization Guidelines; for a long-term equity investment obtained by exchanging non-monetary assets, the initial investment cost is determined in accordance with the relevant provisions of the Non-monetary Asset Exchange Guidelines.

(2) Subsequent measurement and profit and loss recognition methods

The Company adopts the cost method to account for long-term equity investments that the Company can control over the invested entities, and adopts the equity method to account for long-term equity investments in associates and joint ventures. Equity investments in associates, part of which are held indirectly through venture capital institutions, mutual funds, trust companies or similar entities including investment-linked insurance funds, regardless of whether the above entities have a significant impact on this part of the investment, shall be handled in accordance with the relevant provisions of "Accounting Standards for Business Enterprises No. 22 - Recognition and Measurement of Financial Instruments", and the remaining part shall be accounted for using the equity method.

(3) Basis for determining joint control and significant influence on the invested unit

Having joint control over the investee means that activities that have a significant impact on the returns of an arrangement must be decided only with the unanimous consent of the participants sharing control rights, including the sale and purchase of goods or services, management of financial assets, purchase and disposal of assets, research and development activities, and financing activities; having a significant impact on the investee means having a significant impact when holding more than 20% to 50% of the voting capital of the investee. Or, although it is less than 20%, it has a significant influence when one of the following conditions is met: having representatives on the invested unit's board of directors or similar authority; participating in the policy-making process of the invested unit; sending management personnel to the invested unit; the invested unit relies on the technology or technical information of the investing company; and important transactions with the invested unit.

23. Investment real estate

Investment real estate measurement model: cost method measurement

Depreciation or amortization method:

The company's investment real estate categories include leased land use rights, leased buildings, and land use rights held and prepared to be transferred after appreciation. Investment real estate is initially measured based on cost, and the cost model is used for subsequent measurement.

The leased buildings in the Company's investment real estate use the straight-line method to calculate depreciation, and the specific accounting policy is the same as that for fixed assets. The land use rights leased in investment real estate and the land use rights held and prepared for transfer after appreciation are amortized using the straight-line method. The specific accounting policies are the same as those for intangible assets.

24. Fixed assets

(1) Confirmation conditions

Fixed assets refer to tangible assets held for the production of goods, provision of labor services, leasing or operation and management and with a useful life of more than one accounting year. It shall be recognized when the following conditions are met at the same time: the economic benefits related to the fixed asset are likely to flow into the enterprise; the cost of the fixed asset can be measured reliably.

(2) Depreciation method

Category Depreciation method Depreciation period Residual value rate Annual depreciation rate Houses and buildings Year-averaged method 20-40 2.38%-4.85% 2.38%-4.85%

Machinery and equipment Average age method 8-10 9.50%-12.13% 9.50%-12.13%

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-annual Report Transportation Equipment Average Age Method 5-10 9.50%-19.40% 9.50%-19.40% Other Equipment Average Age Method 3-8 11.88%-32.33% 11.88%-32.33%

25. Projects under construction

The Company's projects under construction are mainly self-operated and outsourced. The standard and time point for the transfer of projects under construction into fixed assets shall be based on the fact that the projects under construction have reached the intended usable state. The criteria for judging the intended usable state should meet one of the following conditions: the physical construction (including installation) of the fixed assets has been completed or substantially completed; trial production or trial operation has been carried out, and the results show that the asset can operate normally or can stably produce qualified products, or the trial operation results show that it can operate normally or do business; the amount of expenditure on the fixed assets constructed is very small or almost no longer occurs; the fixed assets purchased and constructed have met the design or contract requirements, or are basically consistent with the design or contract requirements.

26. Borrowing costs

(1) Recognition principles for capitalization of borrowing costs

If the borrowing costs incurred by the company can be directly attributed to the acquisition, construction or production of assets that meet the capitalization conditions, they will be capitalized and included in the cost of the relevant assets; other borrowing costs will be recognized as expenses based on the amount incurred when they are incurred and included in the current profits and losses. Assets that meet the conditions for capitalization refer to fixed assets, investment real estate, inventories and other assets that require a considerable period of acquisition, construction or production activities to reach the intended usable or salable state.

(2) Calculation method of capitalization amount

The capitalization period refers to the period from the point when capitalization of borrowing costs begins to the point when capitalization stops. The period during which capitalization of borrowing costs is suspended is not included. If an abnormal interruption occurs during the purchase, construction or production process and the interruption lasts for more than 3 months, the capitalization of borrowing costs shall be suspended.

Borrowing of special borrowings shall be determined based on the actual interest expense incurred on the special borrowings in the current period, minus the interest income obtained from depositing unused borrowed funds in the bank or the investment income obtained from temporary investments; the amount of general borrowings shall be determined based on the excess of accumulated asset expenditures over the special borrowings. The weighted average of asset expenditures is calculated and determined by multiplying the capitalization rate of the general borrowings occupied, and the capitalization rate is the weighted average interest rate of the general borrowings; if there is a discount or premium on the borrowing, the amount of discount or premium that should be amortized in each accounting period is determined according to the actual interest rate method, and the interest amount of each period is adjusted.

The effective interest rate method is a method of calculating the amortized discount or premium or interest expense based on the actual interest rate of the borrowed money. The actual interest rate is the future cash flow of the loan during the expected duration, and is the interest rate used to discount the current book value of the loan.

27. Biological assets

28. Oil and gas assets

29. Intangible assets

(1) Useful life and its determination basis, estimation, amortization method or review procedure

The company analyzes and determines the useful life of intangible assets when they acquire them. For intangible assets with limited service life, they are amortized within the period expected to bring economic benefits to the enterprise. At the end of the year, the service life and amortization method of the intangible assets are reviewed. If there are differences with the original estimates, corresponding adjustments are made. If it is not foreseeable that the asset will bring economic benefits to the enterprise, it will be determined as an intangible asset with an indefinite useful life and will not be amortized. However, at the end of the year, the useful life will be reviewed. When there is conclusive evidence that its useful life is limited, its useful life will be estimated. At the end of each year, intangible assets with indefinite service life are

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

The review of service life mainly adopts a bottom-up approach, with the relevant departments for the use of intangible assets conducting basic reviews to evaluate whether there are changes in the basis for determining the uncertainty of service life, etc.

(2) Scope of aggregation of R&D expenditures and related accounting treatment methods

The scope of the company's R&D expenditures is mainly determined based on the company's research and development projects, and mainly includes R&D personnel salary, direct investment costs, depreciation expenses and long-term prepaid expenses, design expenses, equipment commissioning expenses, intangible asset amortization expenses, entrusted external research and development expenses, other expenses, etc.

Expenditures in the research phase of internal research and development projects are included in the current profit and loss when incurred; expenditures in the development phase that meet the conditions for recognition as intangible assets are transferred to intangible assets accounting. Expenditures in the development stage are recognized as intangible assets if they meet the following conditions: (1) It is technically feasible to complete the intangible asset so that it can be used or sold; (2) There is the intention to complete the intangible asset and use or sell it; (3) The way in which the intangible asset generates economic benefits includes the ability to prove the use of the intangible asset to produce products. If the product exists in the market or the intangible asset itself has a market, and the intangible asset will be used internally, its usefulness can be proven; (4) It has sufficient technical, financial and other resource support to complete the development of the intangible asset, and has the ability to use or sell the intangible asset; (5) Expenditures attributable to the development stage of the intangible asset can be measured reliably.

Specific criteria for dividing the research phase and development phase of internal research and development projects: The planned investigation phase to obtain new technologies and knowledge should be determined as the research phase, which has the characteristics of planning and exploratory nature; before commercial production or use, the application of research results or other knowledge to a plan or design to produce new or substantially improved materials, devices, products, etc., should be determined as the development phase. This phase has the characteristics of being targeted and having a greater possibility of achieving results.

The company needs to comply with the disclosure requirements of "Medical Device Business" in the "Shenzhen Stock Exchange Self-Regulatory Guidelines for Listed Companies No. 4 - GEM Industry Information Disclosure"

30. Impairment of long-term assets

If there are signs of impairment on the balance sheet date for long-term equity investments, investment real estate, fixed assets, projects under construction, right-of-use assets measured using the cost model, productive biological assets measured using the cost model, oil and gas assets, intangible assets and other long-term assets on the balance sheet date, an impairment test is conducted. If the impairment test results show that the recoverable amount of the asset is lower than its book value, impairment provisions will be made based on the difference and included in the impairment loss.

The recoverable amount is the higher of the asset's fair value less disposal costs and the present value of the asset's expected future cash flows. Asset impairment provisions are calculated and recognized on the basis of individual assets. If it is difficult to estimate the recoverable amount of an individual asset, the recoverable amount of the asset group to which the asset belongs is determined. An asset group is the smallest combination of assets that can independently generate cash inflows.

Goodwill that is presented separately in the financial statements shall be tested for impairment at least annually, regardless of whether there is any indication of impairment. During impairment testing, the book value of goodwill is allocated to asset groups or combinations of asset groups that are expected to benefit from the synergies of a business combination. If the test results indicate that the recoverable amount of an asset group or combination of asset groups containing amortized goodwill is lower than its book value, the corresponding impairment loss will be recognized. The amount of impairment loss first deducts the book value of the goodwill allocated to the asset group or asset group combination, and then deducts the book value of other assets in proportion to the proportion of the book value of other assets in the asset group or asset group combination except goodwill.

Once the above-mentioned asset impairment losses are recognized, the portion whose value has been restored will not be reversed in subsequent periods.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

31. Long-term deferred expenses

The company's long-term deferred expenses refer to various expenses that have been incurred but have a benefit period of more than one year (excluding one year). Long-term deferred expenses are amortized in installments according to the benefit period of the expense item. If a long-term deferred expense item cannot benefit future accounting periods, all the amortized value of the item that has not yet been amortized will be transferred to the current profit and loss.

32. Contract liabilities

The Company lists the obligation to transfer goods or provide services to customers for consideration received or receivable from customers as contract liabilities, and contract assets and contract liabilities under the same contract are presented as a net amount.

33. Employee compensation

(1) Accounting treatment method for short-term compensation

During the accounting period when employees provide services to the company, actual short-term remuneration is recognized as a liability and included in the current profit and loss, except where the accounting standards for enterprises require or allow it to be included in the cost of assets. The employee welfare expenses incurred by the company are included in the current profit and loss or related asset costs according to the actual amount when they are actually incurred. If employee benefits are non-monetary benefits, they are measured at fair value. The company pays social insurance premiums such as medical insurance premiums, work-related injury insurance premiums, maternity insurance premiums, and housing provident funds for its employees, as well as labor union funds and employee education funds withdrawn in accordance with regulations. During the accounting period when employees provide services, the corresponding amount of employee compensation is calculated and determined based on the prescribed accrual basis and accrual ratio, and the corresponding liabilities are recognized and included in the current profit and loss or related asset costs.

(2) Accounting treatment of post-employment benefits

During the accounting period when employees provide services, the company recognizes the deposit amount payable based on the defined contribution plan as a liability and includes it in the current profit and loss or related asset costs. The welfare obligations generated by the defined benefit plan are attributed to the period in which employees provide services based on the formula determined by the expected cumulative welfare unit method, and are included in the current profit and loss or related asset costs.

(3) Accounting treatment method for dismissal benefits

When the company provides dismissal benefits to employees, the employee compensation liabilities arising from the dismissal benefits are recognized at the earliest of the following two times and included in the current profit and loss: when the company cannot unilaterally withdraw the dismissal benefits provided due to the termination of labor relations plan or layoff proposal; when the company recognizes the costs or expenses related to the restructuring involving the payment of dismissal benefits.

(4) Accounting treatment methods for other long-term employee benefits

Other long-term employee benefits provided by the company to employees that meet the conditions of the defined contribution plan shall be handled in accordance with the relevant provisions of the defined contribution plan; in addition, other long-term employee benefits net liabilities or net assets shall be recognized and measured in accordance with the relevant provisions of the defined benefit plan.

34. Estimated liabilities

When the obligation related to a contingency is a current obligation borne by the company, and the performance of the obligation is likely to result in an outflow of economic benefits, and the amount can be reliably measured, the obligation is recognized as a provisional liability. The company makes initial measurement based on the best estimate of the expenditures required to fulfill relevant current obligations. If the required expenditures exist in a continuous range, and the possibility of various outcomes within the range is the same, the best estimate is determined based on the middle value within the range; if multiple projects are involved, the best estimate is determined based on various possible outcomes and related probabilities.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

The book value of estimated liabilities should be reviewed on the balance sheet date. If there is conclusive evidence that the book value cannot truly reflect the current best estimate, the book value should be adjusted based on the current best estimate.

35. Share-based payment

The Company's share-based payment includes equity-settled share-based payment and cash-settled share-based payment. If equity-settled share-based payment is exchanged for services provided by employees, it shall be measured at the fair value of the equity instruments granted to employees. If there is an active market, it will be determined based on the quoted price in the active market; if there is no active market, it will be determined using valuation techniques, including referring to prices used in recent market transactions by parties who are familiar with the situation and voluntarily transacting, referring to the current fair value of other financial instruments that are substantially the same, discounted cash flow methods and option pricing models, etc.

On each balance sheet date, the number of stock options expected to be exercisable is revised based on the latest changes in the number of exercisable persons, the completion of performance indicators and other subsequent information, and the expenses to be allocated in each period are confirmed based on this basis. For option expenses that span multiple accounting periods, the expense can generally be amortized based on the proportion of the length of the waiting period of the option in a certain accounting period to the length of the entire waiting period.

36. Preferred shares, perpetual bonds and other financial instruments

37. Income

(1) Disclose the accounting policies adopted for revenue recognition and measurement according to business type

When the company fulfills its performance obligations in the contract, that is, when the customer obtains control of the relevant goods or services, revenue is recognized based on the transaction price allocated to the performance obligation. Obtaining control over relevant goods means being able to direct the use of the goods and obtain almost all economic benefits from them. Performance obligations refer to the company's commitment in the contract to transfer clearly distinguishable goods to the customer. The transaction price refers to the amount of consideration that the Company expects to be entitled to receive for transferring goods to customers, excluding amounts collected on behalf of third parties and amounts that the Company expects to return to customers.

Whether the performance obligation is performed within a certain period of time or at a certain point in time depends on the terms of the contract and relevant legal provisions. If the performance obligation is performed within a certain period of time, the Company recognizes revenue based on the performance progress. Otherwise, the Company recognizes revenue at a point when the customer obtains control of the relevant assets.

The company determines whether the company is the principal responsible person or agent when engaging in transactions based on whether it has control over the goods or services before transferring them to the customer. If the company is able to control the goods or services before transferring them to the customer, the company is the principal responsible person and recognizes revenue based on the total consideration received or receivable; otherwise, the company acts as the agent and recognizes revenue based on the amount of commissions or fees that it is expected to be entitled to receive. The amount is determined based on the net amount of the total consideration received or receivable after deducting the price payable to other related parties, or based on the established commission amount or ratio.

(2) Similar business uses different business models involving different revenue recognition methods and measurement methods

The company's operating income mainly includes control systems, product sales, and technical services. The specific policies and methods for revenue recognition are as follows:

The control system business between the Company and its customers usually includes multiple commitments such as delivery of goods, on-site installation, commissioning and acceptance. Since equipment delivery and installation and commissioning services cannot be distinguished separately, the Company determines equipment delivery and installation and commissioning services as a performance obligation, and recognizes the revenue from this single performance obligation when the customer's acceptance is completed.

Product sales between the Company and its customers generally involve the transfer of performance obligations only for the delivery of goods. The company transports the goods to the delivery location specified in the contract, and recognizes revenue after the customer signs for receipt.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

The technical service business between the company and its customers usually includes the provision of technical services and debugging and acceptance. The company recognizes technical service revenue when the customer's acceptance is completed.

(3) Contract changes

When the equipment sales contract between the company and the customer is changed:

1. If the contract change adds clearly distinguishable equipment sales, installation services and contract prices, and the new contract price reflects the separate selling price of the new equipment sales and installation services, the company will account for the contract change as a separate contract;

2. If the contract change does not fall into the first situation above, and the equipment sales and installation services that have been transferred can be clearly distinguished from the equipment sales and installation services that have not been transferred on the contract change date, the company will treat it as the termination of the original contract, and at the same time, the unperformed part of the original contract and the contract change part will be combined into a new contract for accounting treatment;

3. If the contract change does not fall into the first situation above, and the equipment sales and installation services that have been transferred and the construction services that have not been transferred cannot be clearly distinguished on the contract change date, the company will account for the contract change as an integral part of the original contract, and the resulting impact on the recognized revenue will be adjusted to the current revenue on the contract change date.

38. Contract costs

Contract costs include incremental costs incurred to obtain the contract and contract performance costs. The incremental costs incurred to obtain a contract ("contract acquisition costs") are costs that would not have been incurred had the contract not been obtained. If the cost is expected to be recovered, the company will recognize it as the contract acquisition cost and as an asset.

Costs incurred to fulfill the contract, which do not fall within the scope of inventory and other accounting standards for enterprises and meet the following conditions, are recognized as contract performance costs as an asset: the cost is directly related to a current or expected contract, including direct labor, direct materials, manufacturing expenses (or similar expenses), costs clearly borne by the user, and other costs incurred solely because of the contract; the cost increases the resources used to perform performance obligations in the future; the cost is expected to be recovered.

The company will recognize the contract performance costs as assets. If the amortization period does not exceed one year or one normal operating cycle at the time of initial recognition, it will be included in the "inventory" item in the balance sheet; if the amortization period is more than one year or one normal operating cycle at the time of initial recognition, it will be included in the "other non-current assets" item in the balance sheet. The company will recognize the contract acquisition costs as assets. If the amortization period does not exceed one year or one normal operating cycle at the time of initial recognition, it will be included in the "other current assets" item in the balance sheet; if the amortization period is more than one year or one normal operating cycle at the time of initial recognition, it will be included in the "other non-current assets" item in the balance sheet.

The Company amortizes the assets recognized as contract acquisition costs and contract performance costs on the same basis as the recognition of commodity revenue related to the assets, and includes them in the current profit and loss. If the amortization period of the assets formed by the incremental cost of acquiring the contract does not exceed one year, it shall be included in the current profit and loss when incurred.

When the book value of assets related to contract costs is higher than the difference between the following two items, the company will make provision for impairment and recognize the excess as asset impairment losses: the remaining consideration expected to be obtained from the transfer of the goods related to the asset; the estimated cost to be incurred for the transfer of the related goods.

If the factors of impairment in the previous period subsequently change, causing the difference between the two aforementioned items to be higher than the book value of the asset, the asset impairment provision that has been originally accrued should be reversed and included in the current profit and loss, but the book value of the asset after reversal shall not exceed the book value of the asset on the date of reversal if no impairment provision is made.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

39. Government subsidies

(1) Types and accounting treatment of government subsidies

Government subsidies refer to the monetary assets or non-monetary assets that the company obtains from the government for free (but does not include the capital invested by the government as the owner). If government subsidies are monetary assets, they shall be measured according to the amount received or receivable. If the government subsidy is a non-monetary asset, it shall be measured at fair value; if the fair value cannot be obtained reliably, it shall be measured at the nominal amount.

Government subsidies related to daily activities shall be included in other income according to the economic and business essence. Government subsidies unrelated to daily activities are included in non-operating income.

Government documents that clearly stipulate that government subsidies are used to purchase, construct or otherwise form long-term assets are recognized as asset-related government subsidies. If the government documents do not clearly stipulate the subsidy objects, and if they can form long-term assets, the part of the government subsidy corresponding to the asset value shall be regarded as the government subsidy related to the assets, and the remaining part shall be regarded as the government subsidy related to the income; if it is difficult to distinguish, the entire government subsidy shall be regarded as the government subsidy related to the income. Government subsidies related to assets are recognized as deferred income. The amount recognized as deferred income will be included in the current profit and loss in installments according to a reasonable and systematic method within the useful life of the relevant assets.

Government subsidies other than those related to assets are recognized as government subsidies related to income. If the income-related government subsidies are used to compensate the enterprise for relevant expenses or losses in the future period, they are recognized as deferred income, and are included in the current profit and loss during the period when the relevant expenses are recognized; if they are used to compensate the enterprise for the relevant expenses or losses that have already occurred, they are directly included in the current profits and losses.

The company obtains policy-based preferential loan interest discounts, and the finance department allocates interest-rate discount funds to the lending bank. If the lending bank provides loans to the company at policy-based preferential interest rates, the actual loan amount received is used as the entry value of the loan, and the relevant borrowing costs are calculated based on the loan principal and the policy-based preferential interest rate; if the finance department directly allocates interest discount funds to the company, the company will offset the corresponding interest rate discounts against related borrowing costs.

(2) Time point for confirmation of government subsidy

Government subsidies are recognized when the conditions attached to the government subsidies are met and can be received. Government subsidies measured according to the amount receivable shall be recognized at the end of the period when there is conclusive evidence that the relevant conditions stipulated in the financial support policy can be met and the financial support funds are expected to be received. Government subsidies other than those measured according to the amount receivable shall be recognized when the subsidy is actually received.

40. Deferred income tax assets/deferred income tax liabilities

(1) Recognition of deferred income tax

Based on the difference between the book value of assets and liabilities and their tax basis (if the tax basis of items not recognized as assets and liabilities can be determined in accordance with tax laws, the tax basis is determined as the difference), deferred income tax assets or deferred income tax liabilities are calculated and recognized according to the applicable tax rate during the period when the asset is expected to be recovered or the liability is settled.

(2) Measurement of deferred income tax

Deferred income tax assets are recognized to the extent that it is probable that taxable income will be available against which the deductible temporary differences can be utilised. On the balance sheet date, if there is conclusive evidence that sufficient taxable income is likely to be obtained in the future period to offset the deductible temporary differences, deferred income tax assets that have not been recognized in previous accounting periods will be recognized. If it is likely that sufficient taxable income will not be available in the future to offset the deferred income tax assets, the book value of the deferred income tax assets will be reduced.

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

Deferred income tax liabilities are recognized for taxable temporary differences related to investments in subsidiaries and associates, unless the company is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not be reversed in the foreseeable future. For deductible temporary differences related to investments in subsidiaries and associates, deferred income tax assets are recognized when the temporary differences are likely to be reversed in the foreseeable future and it is likely to be taxable income that can be used to offset the deductible temporary differences in the future.

(3) Basis for net offset of deferred income tax

When the following conditions are met at the same time, the company will present the deferred income tax assets and deferred income tax liabilities as the net amount after offsetting: it has the legal right to settle the current income tax assets and current income tax liabilities on a net basis; the deferred income tax assets and deferred income tax liabilities are for the same taxpayer with the same tax collection department. It is related to the income tax levied by the entity or to different taxable entities, but in the future during each period when important deferred income tax assets and deferred income tax liabilities are reversed, the taxable entity involved intends to settle the current income tax assets and current income tax liabilities with a net amount or to obtain assets and pay off debts at the same time.

41. Leasing

(1) Accounting treatment method for leasing as lessee

On the start date of the lease period, the Company recognizes right-of-use assets and lease liabilities for leases other than short-term leases and low-value asset leases, and recognizes depreciation expenses and interest expenses respectively during the lease period.

1. Right-of-use assets

On the commencement date of the lease term, the right-of-use asset is initially measured at cost. This cost includes the initial measurement amount of the lease liability, the amount of lease payments net of lease incentives paid on or before the lease commencement date, initial direct costs, etc.

If it is reasonably certain that the ownership of the leased asset will be obtained at the expiration of the lease term, depreciation will be accrued over the estimated remaining useful life of the leased asset; if it cannot be reasonably determined, depreciation will be accrued during the shorter of the lease term and the remaining useful life of the leased asset. When the recoverable amount is lower than the book value of the right-of-use asset, its book value is written down to the recoverable amount.

2. Lease liabilities

Lease liabilities are initially measured based on the present value of the unpaid lease payments at the beginning of the lease term. Lease payments include fixed payments and amounts payable when it is reasonably certain that the option to purchase or the option to terminate the lease will be exercised. Variable lease payments that are not included in the measurement of lease liabilities are included in the current profit and loss when actually incurred.

The company uses the interest rate implicit in the lease as the discount rate; if the interest rate implicit in the lease cannot be reasonably determined, the company's incremental borrowing rate is used as the discount rate. The interest expense of the lease liability in each period during the lease term is calculated based on a fixed periodic interest rate, that is, the discount rate adopted by the Company or the revised discount rate, and is included in financial expenses.

3. As a lessee, the judgment basis and accounting treatment method for simplified treatment of short-term leases and low-value asset leases

For short-term leases with a lease period of no more than 12 months, and leases with a low value when a single asset is new, the company chooses not to recognize right-of-use assets and lease liabilities, and the relevant rental expenses will be included in the current profit and loss or related asset costs on a straight-line basis in each period during the lease term.

(2) Accounting treatment method for leasing as lessor

Beijing Chengyitong Control Technology Group Co., Ltd. 2026 Semi-Annual Report

On the lease commencement date, the Company recognizes leases that substantially transfer almost all risks and rewards related to the ownership of the leased assets as finance leases, and other leases as operating leases.

1. Accounting treatment of operating leases

Rental income from operating leases is recognized on a straight-line basis over the lease term. The initial direct costs are capitalized and included in the current income in installments during the lease term on the same recognition basis as rental income. Variable rent that is not included in the lease receipts is included in rental income when it is actually incurred.

2. Accounting treatment of financial lease

On the start date of the lease, the difference between the sum of the finance lease receivable, the unguaranteed residual value and its present value is recognized as unrealized financing income, and is recognized as lease income in each period when rent is received in the future, and the financial lease assets are derecognized. Initial direct costs are included in the initial recording value of finance lease receivables.

12. Risks related to financial instruments

(1) Various risks arising from financial instruments

The company's goal in risk management is to strike a balance between risks and returns, minimize the negative impact of risks on the company's operating performance, and maximize the interests of shareholders and other equity investors. Based on this risk management objective, the company's basic risk management strategy is to confirm and analyze the various risks faced by the company, establish an appropriate risk tolerance bottom line and conduct risk management, and supervise various risks in a timely and reliable manner to control risks within a limited range.

The Company faces various risks related to financial instruments in its daily activities, mainly including credit risk, liquidity risk and market risk. Management has reviewed and approved policies for managing these risks, summarized below:

1. Credit risk

The Company's credit risk is mainly related to accounts receivable, other receivables and notes receivable. The company formulates relevant policies to control credit risks. At the same time, it evaluates the customer's credit qualifications and sets corresponding credit periods based on the customer's financial status, the possibility of obtaining guarantees from third parties, credit records and other factors such as current market conditions. It regularly conducts continuous monitoring of customer credit records and takes measures to strengthen the recovery management of accounts receivable. For customers with poor credit records, the company will use written reminders, shorten the credit period or cancel the credit period to ensure that the company's overall credit risk is within a controllable range.

2. Liquidity risk

In order to control liquidity risks, the Company comprehensively uses various financing methods such as bill settlement and bank borrowings to maintain a balance between financing continuity and flexibility. As of June 30, 2026, the company has sufficient liquidity and low liquidity risk. The Company's various financial liabilities are listed as follows based on maturity dates:

①Interest rate risk

The interest rate risk faced by the Company mainly comes from bank borrowings, etc. The company's current long-term and short-term borrowings are fixed-rate and floating-rate borrowings, and it manages interest rate risks by closely monitoring interest rate changes and regularly reviewing borrowings.

②Foreign exchange risk

The company's main operations are located in China. Except for its subsidiary CHIEFTAINAMERICAINC established in the United States, which uses US dollars as its accounting standard currency, other companies use RMB as its accounting standard currency. Most of the company's main and ongoing businesses are denominated and settled in RMB, and some of its current customers or suppliers use U.S. dollars and euros for settlement. The risk of exchange rate changes is mainly related to the company's foreign currency monetary assets and liabilities. The company's management is responsible for monitoring exchange rate risks. For foreign currency assets and liabilities, if there is a short-term imbalance, the company will buy and sell foreign currencies at market exchange rates when necessary to ensure that the net risk exposure is maintained at an acceptable level.
