The complete published Chinese 2023 Annual Report may be obtained at http://www.cninfo.com.cn. 1 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. Section I Important Notes, Contents and Definitions The Board of Directors, Board of Supervisors, Directors, Supervisors and Senior Management hereby guarantee that the information presented in this report are true, accurate, and complete without any false records, misleading statements or material omissions, and they will bear joint and several liability for such information. Fu Liquan, the Company's legal representative, Xu Qiaofen, chief accountant, and Zhu Zhuling, person in charge of accounting institution (Accounting Officer) hereby declare and warrant that the financial statements in the annual report are authentic, accurate, and complete. All directors attended the meeting of the Board of Directors for deliberation of this annual report. During the reporting period, there was no significant change in the risks faced by the Company. The Company has been trying to identify all kinds of risks and actively take counter-measures to avoid and reduce the risks. (1) Risk of technology upgrading: The smart IoT industry is a typical technology-intensive industry, featuring extremely fast upgrading. If the Company is unable to keep up with development trends of industrial technologies, to pay full attention to customers' diversified needs, and to devote sufficient R&D investments, it may still face the risk of losing market competitiveness due to discontinuous innovation. By increasing R&D investment, the Company continues to strengthen research on such core technologies as multidimensional awareness, AI large model, video cloud, big data, network communication, cyber security, machine vision, and reserves product, technology, management talent resources for a broader market in the future, so as to achieve sustainable and steady business development. 2 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (2) Risk of business model change: With the development of IoT, artificial intelligence, big data, cloud computing, network communications, among other technologies, as well as the upgrades of smart device applications, the business model in the IoT era may have an impact on the traditional industry development. If an enterprise fails to grasp opportunities brought about by the business model transformation in a timely manner, it may face the risk that the original market pattern becomes broken. The Company continues to focus on and study the major changes in global economy, industry and technology, analyze the industry development logic, and predict the evolution of smart IoT industry, the continuous integration of video, information communication and digital technologies, and the diversification and uncertainty of customer demands. While consolidating its current advantageous market, the Company is also actively exploring and piloting new businesses and new commercial modes, with business and technical layout. (3) Risk of declined local fiscal payment capacity: At present, local fiscal debt is relatively high. If the local fiscal payment capacity declines, it may slow down the growth of industry demand, prolong the construction period of projects, extend the collection of capital, and delay customers' payments. The Company continues to improve the internal control system and optimize the project review methods, select local projects carefully and assess project risks systematically with prudent assessment of the market logic and cash flow balance logic, and reasonable control of risks. In addition, it formulates plans to deal with potential risks such as cash flow shortage, project delay, and payment delay. (4) Exchange rate risk: The Company's export transactions have been mostly settled in U.S. dollars. As our overseas business is in continuous growth, the 3 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. fluctuation of exchange rate may affect our profitability. The Company hedges and avoids exchange rate risks by centralized management of foreign exchange funds and hedging of purchase payments in line with its main use of U.S. dollars as the settlement currency. (5) Risk of product safety: The Company attaches great importance to and continuously strengthens resource investment to ensure safe and reliable system operations so as to respond to product security risks on the Internet. However, hackers attacks, computer viruses, physical security vulnerabilities, natural disasters, accidents, power interruptions, telecommunications failures, terrorism, and warfare events may still occur from time to time, resulting in security vulnerabilities, system failures, or service interruptions. The Company has founded a cyber security committee, and set up a professional security team to develop company-level product safety plans, ensuring product safety in the whole process from demands, design, to coding and testing. At the same time, the Company actively carries out technical exchanges and cooperation with mainstream safety enterprises, safety evaluation agencies and corresponding industry associations to provide customers with safe products and solutions. (6) Intellectual property risk: The promotion of the Company's globalization strategy and its own brand strategy may expose the Company to intellectual property rights risks and patent infringement, as well as such risks as business relations, fluctuations in the public opinion environment, increased legal proceedings and rising costs. With a high priority on technological innovation, the Company has established a mechanism for the protection and management of intangible assets such as innovation achievements, own brands and trade secrets, so as to continuously gather 4 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. advantageous intellectual property assets; with the establishment of an intellectual property compliance and risk control system, the Company continuously strengthens its ability to understand and master intellectual property laws and regulations as well as the administrative and judicial environment in the regions where it operates. (7) Risks of international operations: The Company's products and solutions are available in over 100 countries and regions worldwide. As a result, the Company's international operations may face risks such as trade protectionism, local political conflicts, increasingly complex legal compliance requirements, and a sustained slowdown in global economic growth. The Company actively guards against and responds to risks of international operations by establishing an overseas compliance risk control system. It continuously strengthens the understanding and adaptability of the laws and regulations as well as the political and economic environment of the regions where its business is involved, and formulates differentiated business strategies in accordance with the changes in politics and economy of different regions to reduce operational risks. (8) Supply chain security risks: The Company pays attention to the operating risks of suppliers. By establishing an operating risk data management platform, it monitors the operating conditions of suppliers in real time to avoid potential risks; it promotes diversified supply sources to ensure supply delivery. The profit distribution proposal approved by the board of directors is: Based on the share capital of 3,274,649,389 shares after deducting the Company's repurchased shares (19,819,601 shares) as of December 31, 2023, RMB 3.82 (tax included) of cash dividend and 0 bonus share (tax included) for every 10 shares will be distributed to all shareholders, instead of common reserve capitalizing. 5 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd.

Section III Management Discussion and Analysis I. Industry Overview during the Reporting Period In 2023, China's economy and society embarked on a path of comprehensive recovery and normalization. Under the guidance of enhanced macroeconomic regulation, the economy demonstrated positive momentum, with a growing number of bright spots emerging. Overall, the economic trend was one of steady upward growth.

These developments posed new challenges for the Company.

The world is witnessing an accelerated phase of technological revolution and industrial transformation, while China's economy is undergoing a critical period of transition towards high- quality development, economic structure optimization, and growth driver transformation. Against this backdrop, China is vigorously promoting the digital economy, actively advancing digital industrialization and industrial digitalization, fostering the deep integration of digital technologies with the real economy, and deepening research and application in big data, artificial intelligence, and other fields.

Digitalization and intelligent transformation has always been required in industry development. AI technology is continuously being integrated into industry business, empowering all walks of life to improve quality and efficiency, and driving rapid growth of the AI industry. The emergence of new technologies such as foundation models and multimodal processing is driving innovation in AI applications, accelerating the commercialization and value creation of new AI technologies, and propelling AI to new heights. In the field of artificial intelligence, the Company insists to make high- intensity investment in R&D to promote the large-scale implementation of the artificial intelligence industry and continue to maintain its leading position in the industry. (1) Rapid advancements in technologies like Transformer have led to significant improvements in algorithm performance. 41 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. Traditional small language model approaches rely heavily on supervised learning, which is limited by the size of the training data, the structure of the network, and other factors. As a result, these models have poor generalization ability and adaptability to new scenarios, and their accuracy faces challenges in complex situations. Foundation models can learn rich cross-field knowledge from vast amounts of diverse data due to their larger network parameters. This enables them to develop general-purpose capabilities that are applicable across a wide range of scenarios and tasks. Current mainstream foundation models are based on the Transformer architecture, which excels at understanding and processing long sequences of text, videos, and other continuous information. In the field of visual parsing, Transformers outperform traditional convolutional neural networks in their ability to capture subtle nuances in data. This results in enhanced accuracy and generalization performance for visual parsing tasks. In the field of image generation, diffusion models solve the instability problem of GAN training and gradually become the mainstream image generation model. Compared with other image generation models, the diffusion model can generate better images. (2) The learning ability of foundation models has greatly improved, greatly improving productivity and production efficiency. Traditional small language model approaches are trained and optimized based on individual business scenarios. Due to the significant variations between different business scenarios, the same model exhibits poor adaptability when applied across scenarios. This often necessitates the development of new models tailored to specific scenarios, resulting in a substantial workload. Foundation models have stronger scenario generalization capabilities because they are trained on a massive amount of prior knowledge. Moreover, prompts in various modalities, such as images, voice, and text, can stimulate the emergent intelligence of large models, enabling rapid definition of new functionalities to cater to user needs in a personalized and differentiated manner, thereby enhancing productivity. Fine-tuning large foundation models on small datasets for specific business fields enables rapid capability transfer to new scenarios, effectively addressing diverse and fragmented market demands, and enhancing development efficiency. 42 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (3) Foundation model technology accelerates the diversification of AI applications. The rapid advancement of foundation model technology like Gemini and Sora has propelled AI to new heights, achieving groundbreaking results in areas such as text generation, image generation, and video generation. This is accelerating the diversification of AI applications. Gemini, a multimodal foundation model, showcases exceptional capabilities in understanding images, audio, videos, and text. It is poised to revolutionize natural language processing and multimodal technologies, paving the way for groundbreaking advancements in text generation, search engines, intelligent question answering, and more. Sora, a text-to-video model, possesses remarkable comprehension and generation capabilities. It not only understands what users request in prompts, but also understands how these things exist in the physical world, providing users with a highly realistic and detailed visual experience. From sensing to cognition to generation, foundation models will continuously break through capability boundaries, understand and communicate in more modalities, and have stronger parsing and generation capabilities. They will achieve more complex behavior recognition, image and text data retrieval, intelligent decision-making, and human-computer intelligent interaction functions. This will accelerate the transformation of various industries towards intellgentization and automation, bringing higher efficiency, better services, and more innovative products. Finally, they will work together with industry chain partners to collaborate on innovation and embark on the new journey of AGI. 3.4.1.2 Building A "1+2" AI Capability System AI has emerged as a crucial productivity tool, and the adoption of visual AI is rapidly gaining momentum across diverse industries. We remain committed to our core focus on visual technology, continuously building comprehensive and leading AI research and engineering capabilities. We are centered on industry-specific needs, aiming to make AI accessible to all. Driven by advanced AI technologies, we are constantly solidifying our AI industrialization capabilities. Through years of continuous accumulation, we have established a "1+2" AI capability system, which consists of an architectural framework and two supporting aspects: research capabilities and engineering capabilities. Based on this AI capability system, we have enhanced our algorithm delivery capabilities to address the vast array of fragmented demands, enabling more customers to reap the benefits of AI and enjoy a superior user experience. This "1+2" AI capability system, based on a four-layer technical architecture, establishes a framework for AI research and engineering capabilities. At the scientific research level, we are establishing a comprehensive technical framework across various algorithm domains, continuously solidifying our foundational technologies, and actively exploring novel algorithms. At the engineering level, we have established a research and development system centered on algorithm components, enabling flexible customization of pipeline production and supporting efficient deployment of algorithms to the cloud, edge, and end user. The "1+2" AI capability system has been upgraded from version 1.0, which supports small language models, to version 2.0, which supports foundation models. 43 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (1) Continue to improve the four-layer architecture system to efficiently meet scenario- based AI needs. At the same time, a four-layered technical architecture system composed of the Jinn platform, operator components, general algorithm solutions, and industry algorithm solutions decouples from the technical side, providing end-to-end efficient scenario-based customization and development capabilities, and accelerating the implementation of industry intelligence. ① Continue to upgrade the Jinn Platform and improve the algorithm solution production line. To realize large-scale industrialization of AI, efficient end-to-end solution development and delivery capabilities are needed. The Company continues to focus on building the Jinn Platform, a one-stop AI development platform. Jinn Platform is a one-stop AI development platform for developers, covering the entire AI development workflow from data processing, model training, optimization and porting, algorithm management, and solution development to algorithm verification and testing. In 2017, the Company established a high-performance computing center. In 2019, we launched a full-stack algorithm development platform, enabling closed-loop management of the entire chain from data management to solution delivery. In 2021, we upgraded and released a compositional solution development platform. In 2023, we developed a workflow system for scenario-based algorithm development, which can automatically orchestrate development workflows such as data processing, training, model conversion, and testing. This enables online 44 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. and automated development of scenario-based algorithms, protocol-based operators, and a unified algorithm library, providing model-as-a-service capabilities and enabling multimodal fusion analysis and large model language service deployment. ② Standardize algorithm components to enhance algorithm replicability and adaptability to diverse scenarios. Based on our expertise in scenario-based capabilities, we have streamlined algorithm solutions for different application scenarios and standardized the solutions and their associated algorithm components. By shifting the algorithm development model from "solution-centric" to "algorithm component-centric," we have enhanced algorithm reusability. Additionally, we have upgraded the "algorithm release equals solution release" approach to "model release equals solution release," further shortening the development cycle for intelligent solutions in scenario- based applications and reducing algorithm development costs. ③ Continuously improve algorithm solutions and enhance scenario-based AI capabilities In 2023, we upgraded our scenario-based AI capabilities by delving into customers' production management processes. We provided a rich array of scenario-based AI applications to help customers enhance quality, improve efficiency, and achieve win-win outcomes. We have enhanced the functionality of our industry-specific algorithm solutions to address industry applications and needs. With the multimodal visual analysis capabilities of our Galaxy foundation model, we have upgraded our visual cognition capabilities, continuously improved visual analysis accuracy, enhanced the ability to meet long-tail demand, and developed industry-specific intelligent solutions based on multimodal visual large models. This has further enhanced the level of intelligence in industry-specific businesses. (2) Research capabilities in underlying AI technologies Dahua continues to strengthen its research on underlying AI technologies to ensure the sustained advancement of its algorithms in the industry. By digging deep into the demand and industry pain points, and combining the development trend of AI technologies, especially the foundation model technology, we focus on such fields as single-model multi-tasking, small-sample learning, deep genetic coding technology and trustworthy AI, to build the competitiveness of intelligent products and solutions, and to accelerate the process of commercializing AI. ① Single-model multi-tasking, to maximize the utilization of computing power In the field of vision, the technical path of unified inference through single-model multi-tasking remains powerful in the face of high computing power costs. During the reporting period, the Company continued to delve into single-model multi-tasking technologies. For example, the original algorithm scheme consisting of 5 models for detection, key point, pose, attribute analysis and 45 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. recognition can now be completed by 1 model, with substantially lower complexity of arithmetic scheduling and task scheduling, and 30% increase in the utilization rate of computing power. ② Small sample learning, to increase the efficiency of algorithm development The size of training samples directly affects the performance of deep learning algorithms. Dahua proposed the RWSC-Fusion technology in 2023, which synthesizes massive samples close to real scenes through a small number of samples to train algorithms, thus reducing the dependence of partial algorithms on data. This technology has been applied to scenarios such as security checks and transmission lines, with 10% improvement in the algorithmic recall rate and 30% reduction in the development cost. Related technologies were published in CVPR 2023, one of the top conferences on computational vision. ③ Deep genetic coding, to enable end-to-end cloud feature synergy Due to the non-interpretability of deep learning, heterogeneous feature embeddings generated by the encoders of different models are incompatible and unmeasurable, leading to problems such as incomplete synergy between end-edge clouds in the deployment of small and large model products, and high cost of upgrading product models. To address these issues, Dahua has developed deep genetic coding techniques to allow the feature representation capability of foundation models to be inherited to sub-family models, and in the process of genetic learning, the sub-family models can be customized for different application scenarios and different computing power, and feature embeddings generated by models of the same lineage can be metricated among themselves, thus realizing feature synergy in end-edge clouds, and lowering the cost of product upgrading and O&M. ④ Trustworthy AI, to ensure system security and stability Confronted with risky challenges to AI security, Dahua accelerates the research and implementation of trustworthy AI technologies, such as anti-attack and defense and deep forgery detection, to achieve AI security and trustworthiness. During the reporting period, Dahua continued to research on anti-attack and defense technologies based on diffusion models, moving from the digital domain to the physical domain to enhance the effectiveness of physical attacks. We also developed robust defense methods to significantly improve system security and stability through technologies such as forgery detection and perturbation purification. Relevant technologies have been applied in scenarios such as entrance/exit license plate anti-counterfeiting and door access control anti-counterfeiting detection. (3) AI engineering capabilities In terms of AI engineering capabilities, Dahua has continuously deepened its efforts in areas such as model compression and scenario-based algorithm engineering implementation, to enhance product performance and competitiveness, and expedite AI implementation. 46 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. ① Deeply tap into model compression technologies to enhance product performance and competitiveness. Currently, there are many chips with wide differences in capabilities; employing different model compilers individually causes tremendous engineering investment in algorithm development. Against this background, Dahua has developed its own adaptive model compression and tuning tool. The self-developed hardware-aware adaptive quantization engine technology optimizes the quantization method on the basis of hardware resources and network characteristics, assists in achieving precision tuning with small samples, and optimizes the scale of quantization parameters with less human involvement. Through hardware-aware adaptive model compilation, it is compatible with different training frameworks and various chips, thus addressing the problems of multiple platforms, multiple frameworks, and high threshold of performance tuning. Meanwhile, the QAT quantization technology is employed to overcome the problem of traditional offline quantization accuracy degradation, thus guaranteeing the accuracy of the model on low-bit hardware to achieve training-as-you-get, i.e., consistent accuracy of the model deployed from training to inference. Moreover, the enabled low-bit quantization compression significantly improves the computing power utilization while guaranteeing the accuracy of the commercialized application. ② Enhance the efficiency of scenario-based algorithm implementation by relying on standardized algorithm application paradigms and technical upgrades. Continuously improve the delivery capability of three algorithmic application paradigms, namely "rapid customization by the Company", "convenient development by users" and "general algorithmic paradigm". In order to improve scenario-based AI response capability, we have extracted over 10 general algorithm paradigms from fragmented demand development to improve reproducibility and delivery efficiency. For example, based on such paradigms as "Workwear Compliance", "Changing Event Detection", and "Action Customization", we have undertaken more than 200 algorithm customization requirements, and realized training-free delivery of algorithms, with the delivery efficiency increased by more than 80%. Facing the problem of unstable algorithmic effect in complex scenes due to low accuracy of traditional algorithms for extreme targets (extremely small targets, severely occluded targets, high similarity targets, etc.) encountered in the process of intelligent industry transformation, we investigate the visual cognition ability based on the Galaxy Foundation Model to enhance the perception in complex scenarios, and deepen the level of intelligent industry transformation. 47 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. 3.4.1.3 Constructing a 1+1+N Algorithm Training System Construct a 1+1+N algorithm training system, i.e., algorithm model training + algorithm incremental training + algorithm orchestration. The 1+1+N algorithm training system enriches the algorithm application scenarios, comes closer to clients' business processes, and greatly shortens the algorithm delivery cycle. By providing clients with professional, timely and personalized training, we can quickly build up algorithm capabilities for them, support a wide range of government business needs, assist in corporate intelligent upgrading, renovation and transformation, and establish good customer relations and trust. Two core platforms, i.e. the offline training all-in-one machine and the AI training online platform, have been launched to support such capabilities as on-demand application of training resources, dynamic allocation, multi-person collaboration, task assignment, online verification, online deployment and upgrade, and provide round-the-clock expert technical support. With the training platform, customers can conveniently obtain new algorithms and enjoy professional technical support and services, powering a number of industries such as energy and water conservancy. 3.4.1.4 Boosting Corporate AI Capabilities with the Galaxy Foundation Model Dahua released Galaxy Foundation Model in 2023, a vision-based foundation model that incorporates multimodal capabilities. Foundation models currently released in the industry are mainly generative models, whereby a common model is extended for different industries to handle various downstream tasks. In contrast, the Galaxy Foundation Model is oriented to visual parsing tasks; by building several typical industry visual models, a set of computational framework is extracted, on the basis of which more industry visual models can be built. 48 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (1) Advantages of the Galaxy Foundation Model ① Achieve accuracy and generalizability leap, enhance business competitiveness, and accelerate intelligent market scale expansion. The Galaxy Foundation Model is pre-trained with tons of unlabeled data and fine-tuned on the labeled data, so that the trained model is stable and reliable under extreme targets and extreme scenes. For example, in various situations such as extremely small targets, multi-morphic targets, targets with inconspicuous features, multi-angle targets, blurred images, strong backlight, complex backgrounds, and multi-source images, the results are still stable and reliable, substantially better than those of small models. ② Define new functions through graphic prompts to directly satisfy fragmented functions and efficiently cover new long-tail markets. The Galaxy Foundation Model realizes the upgrading from generalization of algorithm components to that of algorithm solutions. Originally, for small models, the development of an algorithm requires four steps: data annotation, data training, algorithm deployment, and product delivery. Now, the Foundation Model turns the four steps into just one step, with no customization required. Simply with image and text prompts, it can quickly realize new functions, thus greatly shortening the development cycle, and efficiently satisfying the fragmented needs of the long-tailed market. For example, foreign objects such as bird's nests, kites, or plastic bags may cause great potential danger to electric power safety in the power sector. Previously, customized training was required based on specific scenarios and foreign objects, incurring extremely high development costs. Nowadays, such development can be easily achieved by simply giving the foundation model corresponding graphic and textual hints. ③ Break through visual cognition capabilities to understand the entire process of an 49 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. event and open up new space in the intelligent market. Due to technical limitations, small models are unable to realize complex behaviors with many objectives and multiple steps that are difficult to dismantle step by step, such as sweeping waste into sewers, violently throwing objects, and regulating hand-washing. In contrast, the Galaxy Foundation Model can not only extract image features, but fuse the features of different moments so that it can better understand the whole process of an event and recognize complex behaviors. It enables visual intelligence tasks to expand from the previous perceptual parsing and simple cognitive needs to complex cognitive needs, which opens up a new space in the intelligence market. ④ Analyze all scenes autonomously, and streamline intelligent configurations for improved intelligence and usability. Small models are not capable of understanding the whole scene, so rules need to be configured for event analysis, which requires professional support and leads to time-consuming and laborious deployment of algorithms. The Galaxy Foundation Model is capable of understanding the whole scene, and can realize event analysis without rule configuration. Take the power sector as an example, for climbing operation compliance business, the Galaxy Foundation Model automatically understands the climbing scenario, without the need of configuration, which makes it more convenient to use. The foundation model makes intelligent configuration no longer cumbersome and improves the ease of use of intelligence. (2) Coordinated small and foundation models to build affordable scenario-based foundation models In the field of vision, foundation models have made great progress in effectiveness, but with relatively high computing power costs. The input to the visual parsing tasks is visual images, which involve a large amount of data and need to be analyzed 24/7, resulting in high cost for each exclusive path. The cost of using models with ultra-large-scale parameters is high, so significantly cutting the cost of visual parsing foundation model applications is a prerequisite for successful commercialization. Dahua focuses on the large model downsizing techniques and the synergy between small and foundation models to build affordable scenario-based foundation models. The large model downsizing techniques are the basis for building affordable scenario-based large models, which can reduce the basic deployment cost of visual parsing foundation models. The technical steps are as follows: First, control the number of parameters of the basic foundation model, and select the appropriate parameter size based on the task needs, to keep it at the scale of 10 billion through structural design, training and verification, and iterative optimization of a 100 billion foundation model. Second, with the model downsizing technology, the 10 billion parameters are reduced to the scale of one billion through domain distillation and domain quantization, so that the computing 50 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. power demand is reduced to about 10% of that of a mainstream foundation model. Last, due to the stronger comprehension and generalization ability of foundation models, one foundation model is able to substitute dozens of original models, making the overall computing power of the foundation model business controllable. Co-deployment of small and foundation models is the key to building an affordable foundation model system, which ensures controllable computing power costs and accelerates commercialization. The system consists primarily of end-side cloud computing power for computing network fusion and co-deployment of small and large models, whose architecture mainly encompasses the following: the bottom layer of the system consists of a large number of end-side computing power devices with different computing power sizes on the end-side, mostly for small model inference applications, which can be optimized by combining the hardware characteristics to improve the utilization rate of the computing power. The middle layer is the cloud-side computing power pool, mainly for the unified pooling management of heterogeneous computing power, which supports the integration of training and promotion, the fine-tuning of foundation models, and the collaborative optimization of small and foundation models. The top layer is the computing network integrated management and scheduling platform, which carries out unified modeling of small and foundation computing power, constructs system-level computing power network, manages small and foundation model warehouses, and distributes models according to the computing power capacity to complete system-level optimization and scheduling. (3) Foundation model application With visual parsing as the core, we follow up the development of cutting-edge technologies, and make rapid iteration and optimization centering on real-world requirements, to realize value realization from multiple perspectives. We actively promote localized deployment, and realize the 51 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. application of foundation model-related technologies in industrial foundation models, development efficiency, and small model technology upgrading. ① Pilot of industry foundation models Foundation models for urban governance Foundation models for urban governance help upgrade the AI capabilities of urban governance by making the data more accurate and richer. Compared with small models, foundation models for urban governance are more than 10% more accurate on average, with a 50% increase in the number of functions, enabling the realization of a variety of complex cognitive functions in the industry. With powerful comprehension capability, foundation models can simplify the deployment and significantly reduce the deployment cost. A foundation model can replace dozens of small models. With high accuracy of parsed data, such a foundation model is able to reproduce the real twin of a city, which can be reconstructed in a real way, from the full view of the whole city to the condition of each road and every passing vehicle at each intersection. Moreover, the foundation model enable simulation and evaluation of urban road status, simulation and evaluation of urban environment, simulation and deduction of event process, automatic generation of data report and analysis report, among others, so as to realize efficient decision-making and analysis of urban governance. In addition to these advantages, it also demonstrates its strengths in point management. Daily urban management is often faced with the need to regulate numerous decentralized points, which vary widely and thus require different functions to be configured. To address this issue, the foundation model incorporates advanced point governance algorithms. Based on merely one picture, it can automatically analyze and output detailed scene information, and meanwhile intelligently recommends the appropriate function configuration for each point. The launch of this foundation model product not only greatly enhances the functional performance, but also greatly improves the convenience of user interaction. Foundation models for power Foundation models for the power sector can likewise make the data more accurate and richer, thus boosting the upgrading of AI capabilities in the power sector. Compared with small models, the average accuracy of foundation models for the power sector increases by more than 20%, with a 40% increase in the number of functions, which ensures the implementation of a variety of complex cognitive functions in the power sector. Meanwhile, a foundation model not only realizes more than 80 functions of the whole industry, but enables the real twin reproduction of the power scene, from the overall view of the entire substation scene to the operational status of transformers and other instrumentation equipment. The foundation model can also realize functions such as the construction operation drill training, and independent analysis and decision-making of O&M data, so as to realize the efficient decision-making and analysis in the power sector. Moreover, it supports all kinds of foreign object detection functions, such as birds' nests, plastic bags, and balloons. Rather than having to do repetitive tasks such as collecting materials and re-training the model, the corresponding foreign object recognition function can be realized simply through the corresponding 52 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. graphic prompts. Foundation models for more industries In addition to foundation models for urban governance and power, Dahua is also actively deploying algorithms in more industries, such as transportation, and advancing their scenario- based deployments and applications. ② Automated annotation for higher development efficiency The use of foundation models to achieve intelligent pre-annotation, intelligent auxiliary annotation, and annotation process optimization accelerates annotation speed and saves manual input. Currently, intelligent annotation covers various types of materials such as pictures, videos, and audios, and supports a variety of annotation tasks such as target, attribute, segmentation, and tracking. It has achieved satisfactory results on hundreds of annotation categories including motorized vehicles, non-motorized vehicles, various types of animals and objects, with significantly improved annotation efficiency. Meanwhile, intelligent annotation can also substantially improve the annotation quality of difficult cases. Going forward, the foundation model intelligent annotation technology will be applied to the Genius AI open platform to upgrade the level of data processing intelligence, making data processing more efficient and accurate, which will greatly facilitate the extraction and utilization of information and accelerate the intelligent transformation of business processes. ③ Technical upgrading using Transformer-related technologies While developing foundation models for industries, Dahua is actively applying Transformer's multimodal technologies to improve the effectiveness of its algorithms with comparable computing power. The scene adaptability is dramatically improved for such tasks as scene classification, behavioral analysis, and generic defect detection. In the scene classification task, the multimodal model is capable of processing and understanding images and their related descriptions, providing excellent classification results in a variety of complex settings. This technological breakthrough enhances the accuracy of image retrieval systems. For behavioral analysis, the joint analysis of video frames and audio signals enables more accurate recognition of human and vehicle behaviors. In terms of generic defect detection, the Transformer technology shows greater advantages in fault identification by extracting data such as voice, text and images, significantly improving production quality and efficiency. Dahua will continue to innovate based on Transformer technologies and explore more business value from them. ④ Deployment with domestic manufacturing Dahua actively explores technologies related to the deployment of foundation models in domestically manufactured chips. We have introduced chips from major domestic chip companies, migrated and verified visual and multimodal foundation models, and optimized their performance. On this basis, we have successfully accomplished the localization of foundation models for urban 53 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. governance and power. ⑤ Human-computer interaction While actively promoting the R&D of foundation models for industries with vision as the core, Dahua is also actively exploring the application of these models in human-computer interaction and big data retrieval. Currently, large language models are not only equipped with generative capabilities, but also with semantic understanding and reasoning capabilities, which enable them to act as the hub of an intelligent body, and realize task planning, external tool calling, and relevant memory querying based on external knowledge by understanding voice or text prompting information. Based on these capabilities, foundation models can automatically understand and execute a variety of functions in products, such as knowledge quiz, task scheduling, database retrieval, map relationship retrieval, report generation, and tool calling, thus lowering the threshold of user use and interaction costs, and transforming the product interaction paradigm. 3.4.2 Data Intelligence Focusing on video IoT scenarios, Dahua is oriented to the digital intelligent transformation of cities and enterprises, and looks into platform technologies and algorithmic capabilities that enhance governance efficiency, mine data content, and enable data value. Relying on such technologies as cloud native, big data framework, heterogeneous fusion computing, and data center, Dahua provides a one-stop data intelligence base for vision and information fusion, integration, governance, development, and services. Based on technologies such as artificial intelligence, figure-digital fusion, data mining, and knowledge mapping, it digs deeply into the connotation of view data, and builds figure-digital fusion high-value data warehouses, to unleash the value of data, facilitate the digital transformation and development of cities and enterprises, and jointly pioneer the new development of the digital society and economy. In 2023, Dahua continued to dig deep into the value of view data. By integrating production and business data, it comprehensively stimulated view application innovation. Taking data value calculation as an impetus, it consolidated the basic capability of big data platforms, and built up industry-specific capabilities such as AI+big data fusion calculation frameworks and heterogeneous calculation of diverse data, thus empowering data application innovation and boosting the digital 54 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. and intellectual transformation of government and enterprises.

The key audit matters that we identified in the audit are as follows: Key Audit Matters How the matter was addressed in the audit A.

See Notes III (26) for details. B. Recoverability of accounts receivable At the end of 2023, Dahua’s net value of receivables was We evaluated the recoverability of accounts receivable by the following RMB 16,276,804,000 yuan. The management needs to procedure: ① Understand the management's internal controls of key financial make significant judgments about the identification of reporting related to credit control, account recovery and assessment of accounts receivable impairment accounts, the likelihood of impairment provision for receivables, and evaluate the effectiveness of the design inward cash flows of future customers.

IV. Other Information The management of Dahua (hereinafter referred to as the Management) is responsible for the other information. The other information includes the information covered in Dahua's annual report in 2023, but excludes the financial statements and our audit report. Our opinion on the financial statements does not cover the other information and we do not and will not express any form of assurance conclusion thereon. In combination with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard. V. Responsibilities of Management and Those Charged with Governance for the Financial Statements The Management is responsible for preparing the financial statements in accordance with the requirements of Accounting Standards for Business Enterprises to achieve a fair presentation, and design, implement and maintain necessary internal control to ensure that the financial statements are free from material misstatements, whether due to frauds or errors. In preparing the financial statements, the Management is responsible for assessing Dahua's ability to continue operating, disclosing matters related to continuous operation (if applicable) and using the hypothesis of continuous operation unless there is a plan to liquidate, terminate operations or no other realistic options. The management is responsible for supervising the financial reporting process of Dahua. VI. CPA's Responsibilities for the Audit of the Financial Statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an audit report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the audit standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users made on the basis of these financial statements. 214 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. As part of an audit in accordance with the audit standards, we exercise professional judgment and maintain professional skepticism throughout the audit. We also: (I) Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures to address those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. (II) Understand the internal control related to the audit in order to design appropriate audit procedure. (III) Evaluate the appropriateness of accounting policies used, and the reasonableness of accounting estimates and related disclosures made, by the Management. (IV) Conclude on the appropriateness of using the going concern assumption by the Management. At the same time, draw a conclusion, based on the audit evidence obtained, on whether there is significant uncertainty in matters or situations that may cause major doubts about Dahua's ability in continuous operation. If we conclude that a material uncertainty exists, we are required to draw attention in our audit report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the information available up to the date of our audit report. However, future events or conditions may result in Dahua's inability to continue operating. (V) Evaluate the overall presentation (including the disclosures), structure and content of the financial statements, and whether the financial statements fairly reflect the relevant transactions and events. (VI) Obtain sufficient and appropriate audit evidence regarding the financial information of the entities or business activities within Dahua to express an opinion on the consolidated financial statements. We are responsible for guiding, supervising, and implementing the group audit, and remain solely responsible for our audit opinion. We have communicated with those charged with governance on such matters as the scope of audit as planned, the schedule and material audit findings, including the defects in the internal control that are worth paying attention to found in this audit. We have also provided those charged with governance with a statement on observing the professional ethics related to independence, and communicated with those charged with governance on all the relationships and other matters that might be reasonably deemed to affect our independence, and relevant preventative measures. From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our audit report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The accounting treatment of business combinations involving entities under common control and business combinations involving entities not under common control Business combination involving entities under common control: The assets and liabilities acquired by the merging party in business combination (including goodwill incurred in the acquisition of the merged party by ultimate controlling party) shall be measured at the book value of the assets and liabilities of the merged party in the consolidated financial statements of the ultimate controlling party on the date of combination. The difference between the book value of the net assets obtained and the book value of the consideration paid for the combination (or total nominal value of the issued shares) is adjusted to capital premium in capital reserve. Adjustments shall be made to retained earnings in the event that the share premiums in the capital reserves are not sufficient for write-down. Business combination involving entities not under common control: The cost of combination is the fair value of the assets paid, the liabilities incurred or assumed, and the equity securities issued by the acquirer to acquire the control of the acquiree on the date of acquisition. Where the cost of combination is higher than the fair value of the identifiable net assets acquired from the merging party in business combination, such difference shall be recognized as goodwill; where the cost of combination is less than the fair value of the identifiable net assets acquired from the merging party in business combination, such difference shall be charged to the profit or loss for the period. The identifiable assets, liabilities and contingent liabilities of the acquiree obtained in the combination that satisfy the recognition criteria shall be measured by the fair value on the date of acquisition. The fees which are directly related to the business combination shall be recognized as the profit or loss in the period when the costs are incurred; the transaction expenses of issuing equity securities or debt securities for business merger shall be initially capitalized for equity securities or debt securities. 7. Criterion for judgment of control and preparation method of consolidated financial statements (1) Criterion for judgment of control The scope of consolidation of the consolidated financial statements is based on controlling interests and includes the Company and all the subsidiaries. Control means that the Company has the power with respect to the investee to obtain variable returns by engaging in relevant activities of the investee, and has the ability to influence the amount of its returns by applying its power with respect to the investee. (2) Preparation method of consolidated financial statements 247 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. The Company treats the enterprise group as a single accounting entity and prepares the consolidated financial statements in accordance with the unified accounting policy to reflect the Group's overall financial position, operating results, and cash flow. The influence from the internal transactions between the Company and the subsidiaries or between different subsidiaries shall be eliminated. Internal transactions show that impairment loss of relevant assets shall be recognized as such loss in full. In preparing the consolidated financial statements, where the accounting policies and the accounting periods are inconsistent between the Company and subsidiaries, the financial statements of subsidiaries are adjusted in accordance with the accounting policies and accounting period of the Company. The shares belonging to minority shareholders in owner's equity, the net profit or loss and the comprehensive income of the subsidiary of the current period are presented separately under the owners' equity in the consolidated balance sheet, the net profits, and the total comprehensive income in the consolidated income statement respectively. Where losses attributable to the minority shareholders of a subsidiary of the current period exceed the minority shareholders' interest entitled in the shareholders' equity of the subsidiary at the beginning of the period, the excess shall be offset against the equity of minority shareholders. ① Acquisition of Subsidiaries or Business For acquisition of subsidiaries or business due to business combination involving entities under common control during the reporting period, the operating results and cash flow of such subsidiaries or business from the beginning to the end of the reporting period when the merger occurs are included in the consolidated income statement; and the opening balance and comparative figures of the consolidated financial statements should be adjusted simultaneously as if the consolidated reporting entity has been in existence since the beginning of the control by the ultimate controlling party. In connection with imposing control over the investee under common control due to additional investment and other reasons, the equity investment held before gaining the control of the combined party is recognized as relevant profit or loss, other comprehensive income and changes in other net assets at the later of the date of acquisition of the original equity and the date when the combining and the merged parties are under common control, and shall be written down to the opening balance retained earnings or current profit or loss in the comparative reporting period. Additional subsidiaries or business due to business combination involving entities not under common control during the reporting period will be included in the consolidated financial statements as of the date of acquisition on the basis of the fair value of the identifiable assets, liabilities or contingent liabilities determined on the date of acquisition. In connection with imposing control over the investee not under common control due to additional investment and other reasons, the equity of acquiree held before acquisition date shall be remeasured at the fair value of such equity on the acquisition date and the difference between fair value and book value shall be recognized as investment income in current period. Other comprehensive income that may later be reclassified into profit or loss and changes in other owner's equity accounted by equity method contained in the acquiree's equity held before the acquisition date shall be transferred to current investment gains on the date of acquisition. ② Disposal of Subsidiaries or Business a. General Treatment When losing control of the investee due to partial disposal of the equity investment, or any other reasons, the remaining equity investment is remeasured at fair value at the date in which control is lost. The sum of consideration 248 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. received from disposal of equity investment and the fair value of the remaining equity investment, net of the difference between the sum of the Company's previous share of the subsidiary's net assets recorded from the acquisition date or combination date and the sum of goodwill, is recognized in investment income in the period in which control is lost. Other comprehensive income that may later be reclassified into profit or loss and changes in other owner's equity accounted by equity method in connection with the equity investment of the original subsidiaries shall be transferred to the current investment gains when the control is lost. b. Disposal of Subsidiary Achieved by Stages When the equity investment of subsidiaries is disposed of through multiple transactions until the control is lost, such multiple transactions are generally treated as a package deal if the terms, conditions, and economic impact of the transactions to dispose of the subsidiary's equity investment satisfy one or more of the following conditions: These transactions are achieved at the same time or the mutual effects on each other are considered; A complete set of commercial results can be achieved with reference to the series of transactions as a whole; Achieving a transaction depends on achieving of at least one of the other transaction; One transaction recognized separately is not economical, but it is economical when considered together with other transactions. If multiple transactions are recognized as a package deal, these transactions shall be subject to accounting treatment as a transaction to dispose of the subsidiaries and lose control. The differences between the price on each disposal and disposal of investment on the subsidiary's net assets shall be recognized in other comprehensive income in the consolidated financial statements, and included in profit or loss for the period when the control is lost. If the transactions are not a package deal, accounting treatment for partial disposal of equity investments of the subsidiary without losing control shall be applied before control is lost. When the control is lost, general accounting treatment for disposal of a subsidiary shall be used. ③ Acquisition of Minority Interest of Subsidiaries The Company shall adjust the share premium in the capital reserve of the consolidated balance sheet with respect to any difference between the long-term equity investment arising from the purchase of minority interest and the net assets attributing to the parent company continuously calculated on the basis of the newly increased share proportion as of the acquisition date or date of combination or, adjust the retained earnings if the share premium in the capital reserve is insufficient for write-down. ④ Partial Disposal of Equity Investment in Subsidiaries without Losing Control The difference between the disposal consideration and the share of net assets in the subsidiaries calculated from disposal of long-term equity investment as of the date of acquisition or combination date shall be adjusted to share premium in the capital reserve in the consolidated balance sheet. Adjustments shall be made to retained earnings in the event that the share premiums in the capital reserves are not sufficient for write-down. 249 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. 8. Classification of joint venture arrangement and accounting treatment methods for joint operation Joint venture arrangement is classified into joint operation and joint venture. Joint operation means the joint venture arrangement in which the joint venture parties have the assets and assume the liabilities related to such arrangement. The Company recognizes the following items related to the share of interests in the joint operation: (1) The assets separately held by the Company and assets jointly held as recognized by the share of the Company; (2) The liabilities separately assumed by the Company and liabilities jointly assumed as recognized by the share of the Company; (3) Income from selling the share of the Company in the output of the joint operation; (4) Income from joint operation of the sold output as recognized by the share of the Company; (5) The expenses separately incurred and expenses jointly incurred as recognized by the share of the Company; The Company adopts the equity method for the investment of the joint venture. For details, refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 20. Long-term equity investment. 9. Recognition criteria of cash and cash equivalents Cash means the cash on hand and deposits that are available for payment at any time of the Company. Cash equivalents mean the investments held by the Company which are short-term, highly liquid, easy to be converted into known amounts of cash and have little risk of value change. 10. Conversion of transactions and financial statements denominated in foreign currencies (1) Foreign currency transactions Foreign currency transactions shall be translated into functional currency at the spot exchange rate on the day when the transactions occurred. The Balance of foreign currency monetary items shall be translated at the spot exchange rate on the balance sheet date. The resulting exchange differences are recognized in profit or loss for the current period, except for those differences related to the principal and interest on a specific-purpose borrowing denominated in foreign currency for acquisitions, construction, or production of the qualified assets, which should be incuded in current profit and loss. (2) Translation of foreign currency financial statements All assets and liabilities in balance sheet are translated based on spot exchange rate on the balance sheet date; owners' equity items other than "undistributed profit" are translated at a spot exchange rate when accrued. Revenue and expense items in the income statement are translated at a spot exchange rate at the transaction occurrence date. For disposal of overseas operation, the translation difference as stated in the foreign currency financial statements relating to overseas operation, is accounted for in the profit and loss account in the current period from owners' equity items. 250 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. 11. Financial instruments A financial asset, financial liability or equity instrument is recognized when the Company becomes a party to the financial instrument contract. (1) Classification of the financial instruments According to the Company's business model for management of the financial assets and the contractual cash flow features of the financial assets, the financial assets, when initially recognized, are classified as: financial assets at amortized cost, financial assets at fair value through other comprehensive income (debt instruments) and financial assets at fair value through profit or loss. The financial assets which satisfy the following conditions, and are not designated as financial assets at fair value through profit or loss will be classified by the Company as financial assets at amortized cost: ① The business model is designed to collect the contractual cash flow; ② The contractual cash flow is only used to pay the principal and the interests based on the outstanding principal amount. The financial assets which satisfy the following conditions, and are not designated as financial assets at fair value through profit or loss will be classified by the Company as the financial assets (equity instruments) at fair value through other comprehensive income: ① The business model is designed to both collect the contractual cash flow and sell the financial assets; ② The contractual cash flow is only used to pay the principal and the interests based on the outstanding principal amount. For non-trading investments in equity instruments, the Company may, at the time of initial recognition, irrevocably designate them as financial assets (equity instruments) at fair value through other comprehensive income. Such designation is based on the individual investments, and relevant investments fall within the definition of the equity instrument from the perspective of the issuer. Except for the financial assets at amortized cost, and financial assets at fair value through other comprehensive income, all the remaining financial assets are classified as the financial assets at fair value through profit or loss. At the time of initial recognition, the financial assets which should have been classified as financial assets at amortized cost or financial assets at fair value through other comprehensive income can be irrevocably designated by the Company as financial assets at fair value through profit or loss if the accounting mismatch can be eliminated or significantly reduced. The financial liabilities, when initially recognized, are classified as: financial liabilities at fair value through profit or loss and financial liabilities at amortized cost. Financial liabilities which meet one of the following conditions will be, when initially measured, designated as financial liabilities at fair value through profit or loss: ① Such designation may be able to eliminate or significantly reduce the accounting mismatch; ② The portfolio of financial liabilities or the portfolio of financial assets and financial liabilities shall be subject to management and performance evaluation on the basis of fair value according to the enterprise risk management or investment strategy contained in the formal documentations, and a report shall be made to the key management personnel within the enterprise on this basis; ③ Such financial liabilities shall contain embedded derivatives to be split separately. (2) Recognition and measurement of financial instruments ① Financial assets at amortized cost Financial assets at amortized cost include notes receivable, accounts receivable, other receivables, long-term receivables and creditors investment, which shall be initially measured at fair value, and the relevant transaction expenses should be initially capitalized; The accounts receivable that do not contain material financing compositions 251 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. and those for which the Company decides to not take into account the financing compositions of no more than one year shall be initially measured at the contract transaction price. The interest calculated by effective interest method during the holding period is recorded into the current profit and loss. At the time of recovery or disposal, the difference between the price obtained and the book value shall be included in the current profit or loss. ② Financial assets measured at fair value and whose changes are included in other comprehensive income (debt instruments) Financial assets measured at fair value and its changes are included in other comprehensive income (debt instruments) include receivables financing and investments in other creditor's rights. They are initially measured at fair value, and the relevant transaction expenses should be initially capitalized. These financial assets are subsequently measured at fair value, and the change in fair value, other than the interest, the impairment loss or profit and the profit or loss on foreign exchange, shall be included in other comprehensive income. Upon derecognition, the cumulative profits or losses previously included in other comprehensive income shall be removed from other comprehensive income and included in the profit or loss for the period. ③ Financial assets measured at fair value and whose changes are included in other comprehensive income (equity instruments) Financial assets at fair value through other comprehensive income (equity instruments) include investment in other equity instruments. They are initially measured at fair value, and the transaction expenses shall be initially capitalized. These financial assets are subsequently measured at fair value, and the change in fair value shall be included in other comprehensive income. The dividends obtained shall be included in the profit or loss for the period. Upon derecognition, the cumulative profits or losses previously included in other comprehensive income shall be removed from other comprehensive income and included in the carry-forward retained earnings. ④ Financial assets measured at fair value and whose changes are included in the current profit or loss Financial assets at fair value through profit or loss include trading financial assets, derivative financial assets, and other non-current financial assets. They are initially measured at fair value, and the transaction expenses related to them are included in the current profit or loss. These financial assets are subsequently measured at fair value, and the change in fair value shall be included in the profit or loss for the period. ⑤ Financial liabilities at fair value through profit or loss in this period Financial liabilities at fair value through profit or loss include trading financial liabilities and derivative financial liabilities. They are initially measured at fair value, and the transaction expenses related to them are included in the profit or loss for the period. These financial liabilities are subsequently measured at fair value, and the change in fair value shall be included in the profit or loss for the period. Upon derecognition, the difference between their book value and the consideration paid is included in the profit or loss for the period. ⑥ Financial liabilities at amortized cost Financial liabilities at amortized cost include short-term loans, notes payable, accounts payable, other payables, long- term loans, bonds payable, and long-term payables. They are initially measured at fair value, and the transaction expenses shall be initially capitalized. The interest calculated by effective interest method during the holding period is recorded into the current profit and loss. Upon derecognition, the difference between the consideration paid and the book value of these financial liabilities is included in the current profit or loss. (3) Derecognition and transfer of financial assets 252 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. When one of the following conditions is met, financial assets are derecognized by the Company: ① The contractual right to receive cash flows from financial assets is terminated; ② The financial assets have been transferred and nearly all the risks and rewards related to the ownership of the financial assets have been transferred to the transferee; ③ The financial assets have been transferred and although the Company neither transfers or retains all the risks and rewards related to the ownership of the financial assets, the Company retains no control of the financial assets; If the Company and the counterpary modify or re-negotiate the contract, which constitute material modifications, the original financial assets will be derecognized and a new financial asset will be recognized according to the modified terms. The financial assets when transferred will not be derecognized if the Company has retained nearly all the risks and rewards related to the ownership of the financial assets. The substance-over-form principle shall be adopted while making judgment on whether the transfer of financial assets satisfies the above conditions for termination of recognition. The transfer of financial assets can be classified into entire transfer and partial transfer. If the transfer of an entire financial asset satisfies the conditions for termination of recognition, the difference between the two amounts below shall be recorded into profit or loss for the period: ① The book value of the financial asset transferred; ② The consideration received as a result of the transfer, plus the accumulative amount of the change in fair value previously recorded into the owners' equity (in cases where the transferred financial assets are financial assets measured at fair value and whose changes are included in other comprehensive income (debt instruments)). If the partial transfer of financial assets satisfies the conditions for termination of recognition, the overall book value of the transferred financial asset shall be apportioned according to their respective relative fair value between the recognition terminated part and the remaining part, and the difference between the two amounts below shall be recorded into profit or loss for the current period: ① The book value of the derecognized portion; ② The sum of consideration of the derecognized portion and the corresponding portion of accumulated change in fair value previously recorded into owners' equity (in cases where the transferred financial assets are financial assets measured at fair value and whose changes are included in other comprehensive income (debt instruments)). Financial assets will still be recognized if they fail to satisfy the conditions for termination of recognition, with the consideration received recognized as a financial liability. (4) Derecognition of financial liabilities When the current obligation under a financial liability is completely or partially discharged, the recognition of the whole or relevant portion of the liability is terminated; an agreement is entered between the Company and a creditor to replace the original financial liabilities with new financial liabilities with substantially different terms, terminate the recognition of the original financial liabilities as well as recognize the new financial liabilities. If all or part of the contract terms of the original financial liabilities are substantially amended, the recognition of the original financial liabilities will be terminated in full or in part, and the financial liabilities whose terms have been amended shall be recognized as a new financial liability. When recognition of financial liabilities is terminated in full or in part, the difference between the book value of the financial liabilities terminated and the consideration paid (including transferred non-cash assets or new financial liability) is recognized in profit or loss for the current period. Where the Company repurchases part of its financial liabilities, the book value of such financial liabilities will be allocated according to the relative fair value between the continued recognized part and terminated part on the 253 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. repurchase date. The difference between the book value of the financial liabilities terminated and the consideration paid (including transferred non-cash assets or new financial liability) is recognized in profit or loss for the current period. (5) Method of determining the fair values of financial assets and liabilities The fair value of a financial instrument that is traded in an active market is determined at the quoted price in the active market. The fair value of a financial instrument that is not traded in an active market is determined by using a valuation technique. The Company uses the valuation technique when it is applicable under current conditions and there are enough available data and other information to support and the technique should maximize the use of relevant observable. It chooses the inputs which are consistent with the asset or liability's characteristics considered by market participants in the transaction of the relevant asset or liability and makes the maximum use of relevant observable inputs. Unobservable inputs are used under the circumstance that the relevant observable inputs cannot be obtained or not feasible. (6) Test method and accounting treatment for impairment of financial assets The Company bases its impairment accounting treatment on the expected credit loss on the financial assets at amortized cost, the financial assets at fair value through other comprehensive income (debt instruments), and the financial guarantee contracts. Taking into the reasonable and well-grounded information including past matters, current situation and prediction of future economic conditions, the Company calculates the possibly weighted amount of the present value of the difference between the cash flows receivable under the contract and the cash flows expected to be received, taking the risk of default as the weight, and recognizes the expected credit loss. The Company will always measure the loss provision for the accounts receivable and contract assets arising from the transactions regulated by "Accounting Standard for Business Enterprises No.14 - Revenue", whether they contain material financing compositions or not, by the amount of the expected credit loss throughout the duration. For the lease receivables arising from the transactions regulated by "Accounting Standard for Business Enterprises No. 21 - Lease", the Company will always measure the loss provision for the accounts receivable, by the amount of the expected credit loss throughout the duration. For other financial instruments, the Company assesses at each balance sheet date the changes in the credit risk of relevant financial instruments since initial recognition. By comparing the risk of default of financial instruments on the balance sheet date with the risk of default on the initial recognition date, the Company determines the relative change in the risk of default over the expected life of financial instruments to assess whether the credit risk of financial instruments has increased significantly since initial recognition. If the financial instrument becomes overdue for more than 30 days, the Company believes that the credit risk of this financial instrument has been significantly increased, unless there are concrete evidences that the credit risk of this financial instrument has not been significantly increased upon initial recognition. If the financial instrument carries low credit risk at the balance sheet date, the Company believes that the credit risk of this financial instrument is not significantly increased upon initial recognition. If the credit risk of this financial instrument has been significantly increased upon initial recognition, the Company measures its loss provision in accordance with the amount equivalent to the expected credit loss of the financial instrument throughout the duration; if the credit risk of this financial instrument is not significantly increased upon initial recognition, the Company will measure the loss provision of this financial instrument by the amount of its expected credit loss in the 12 months to come. The increased or reversed amount of the loss provision resulting therefrom is included in the current profit or loss as the impairment loss or profit. For the financial assets measured at fair value and whose changes are included in other comprehensive income (debt instruments), their loss reserve is recognized in other comprehensive income and the impairment loss or gain is included in the current profit or loss without reducing the book value of such financial assets listed in the balance sheet. 254 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. If there are objective evidences showing that a certain account receivable has been subject to credit impairment, the Company will accrue impairment provision for this account receivable on the individual item basis. The Company divides the financial instruments other than the above accounts receivable with the bad debt provision accrued based on single item into several combinations based on the credit risk characteristics, and determines the expected credit loss on a combined basis. The combination categories of the Company for which the expected credit loss is accrued, including notes receivable, accounts receivable, receivables financing, other receivables, contract assets (including contract assets presented in other non-current assets) and long-term receivables (including long- term receivables due within 1 year presented in non-current assets due within 1 year) and the basis for determination thereof are shown as follows: Item Combination Basis of Determination Category Notes receivable With reference to the historical credit loss experience, combined with the current situation and the prediction Bill type of future economic conditions, the expected credit Receivables Financing loss is calculated through the exposure at default and the expected credit loss rate throughout the duration. With reference to the historical credit loss experience, combined with the current situation and the prediction Aging Accounts receivable, other receivables of future economic conditions, the expected credit mechanics loss is calculated through the exposure at default and the expected credit loss rate throughout the duration. Related parties With reference to the historical credit loss experience, that are combined with the current situation and the prediction included in the of future economic conditions, the expected credit Accounts receivable, other receivables scope of loss is calculated through the exposure at default and consolidated the expected credit loss rate throughout the duration. financial statements With reference to the historical credit loss experience, Contract assets (including contract combined with the current situation and the prediction Nature of the assets presented in other non-current of future economic conditions, the expected credit funds assets) loss is calculated through the exposure at default and the expected credit loss rate throughout the duration.

Significant Accounting Polices and Accounting Estimates - 11. Financial instruments 16. Contract assets (1) Recognition method and criteria of contract assets The Company lists contract assets or contract liabilities in the balance sheet according to the relationship between performance obligations and customer payments. Considerations that the Company has the right to collect for commodities transferred or services provided to customers (and such right depends on other factors than passing of time) are presented as contract assets. The contract assets and contract liabilities under the same contract are presented in net amount. The Company separately presents the right possessed to collect consideration from customers unconditionally (only depending on the passing of time) as accounts receivable. (2) Determination method and accounting treatment method for the expected credit loss of contract assets For details, refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments 17. Inventories (1) Category of inventory Inventories are classified as raw materials, commodity stocks, products in progress and materials commissioned for processing. The inventories are initially measured at cost, which comprises the cost of purchase, cost of conversion and other expenditure incurred in bringing the inventories to their present location and condition. (2) Determination of cost Cost of inventories is determined using the weighted average method. (3) Basis for the determination of net realizable value and different type of inventories At the balance sheet date, inventories are measured at the lower of cost and net realizable value. When the cost of inventories is higher than their net realizable value, reserve for stock depreciation shall be accrued. The net realizable value means the amount after deducting the estimated cost of completion, estimated selling expenses and relevant taxes from the estimated selling price of inventories in the daily activities. Net realizable value of held-for-sale commodity stocks, such as finished goods, goods-in-stock, and held-for-sale raw materials, during the normal course of production and operation, shall be determined by their estimated sales less the related selling expenses and taxes; the net realizable value of material inventories, which need to be processed, during the normal course of production and operation, shall be determined by the amount after deducting the estimated cost of completion, estimated selling expenses and relevant taxes from the estimated selling price of finished goods; the net realizable value of inventories held for execution of sales contracts or labor contracts shall be calculated on the ground of the contracted price. If an enterprise holds more inventories than the quantity stipulated in 256 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. the sales contract, the net realizable value of the exceeding part shall be calculated on the ground of general selling price. If the Company accrues the reserve for stock depreciation based on the combination, the combination category and the basis for determination thereof as well as the basis for determination of the net realizable value of different types of inventories are shown as follows: Combination category of Basis for determination of the Basis for determination of the net inventories combination realizable value Raw materials Inventory category Estimated selling price of inventories - Work-in-progress Inventory category estimated cost of completion - estimated selling expenses - relevant Finished goods Inventory category taxes Contract performance costs Inventory category If the factors influencing the write-down of the inventory value have disappeared, resulting in higher net realizable value of inventories than their book value after the reserve for stock depreciation is accrued, a reversal shall apply in the amount of reserve for stock depreciation previously accrued, and the reserved amount shall be included in the current profit or loss. (4) Inventory system The perpetual inventory system is adopted. (5) Amortization of low-value consumables and packaging materials ① Low-value consumables are amortized using the immediate write-off method; ② Packaging materials are amortized using the immediate write-off method. 18. Holding assets for sale (1) Recognition criteria and accounting treatment method An asset of which the book value is recovered mainly through sale (including exchange of non-monetary asset of a commercial nature), rather than continuous use of a non-current asset or a disposal group, is classified as a holding asset for sale. A non-current asset or disposed group is classified by the Company as holding for sale if it meets the following criteria at the same time: ① Immediate sale could be made under the current circumstances in accordance with the convention of selling such kind of assets or disposal groups in similar transactions; ② Selling is highly likely to occur, i.e., the Company has made a resolution on a sales plan and obtained confirmed purchase commitments, and the sales is predicted to be completed within 1 year. If required by relevant provisions that selling shall only be made after approved by the relevant competent authority or supervision department of the Company, such approval should have been obtained. If the book value of the non-current assets (excluding financial assets, deferred income tax assets, and assets to constitute payroll payable) or disposal groups classified as holding for-sale assets is higher than the net amount after deducting the selling expenses from the book value, the book value will be written down to the net amount after deducting the selling expenses from the fair value, and the amount written down will be recognized as the impairment loss of assets and included in the current profit or loss. At the same time, the impairment provision for holding for-sale assets will be accrued. 257 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (2) Identification criteria and presentation method for termination of business Termination of business is a separately distinguishable constituent part that satisfies one of the following conditions and that has been disposed of or classified by the Company as held for sale: ② This constituent part represents an independent primary business or a separate principal operating area; ② This constituent part is part of an associated plan to dispose of an independent primary business or a separate principal operating area; ③ This constituent part is a subsidiary acquired for resale. The profit or loss from going concern and the profit or loss from discontinued operation will be separately presented in the income statement. The operating profit or loss and the profit or loss from disposal, including impairment loss and reversed amount from discontinued operation, will be presented as the profit or loss from discontinued operation. For the discontinued operation presented in the current period, the Company will present the information previously presented as the profit or loss from going concern as the profit or loss from discontinued operation during the comparable accounting period. 19. Long-term receivables Refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments 20. Long-term equity investment (1) Criterion of joint control and significant influence Joint control is the contractually agreed sharing of control of an arrangement, and exists only when requiring the unanimous consent of the parties sharing control before making decisions about the relevant activities of the arrangement. The Company together with the other joint venture parties can jointly control over the investee and are entitled to the right of the net assets of the investee, as the investee is joint venture of the Company. Significant influence refers to the power to participate in making decisions on the financial and operating policies of an enterprise, but not the power to control, or jointly control, the formulation of such policies with other parties. Where the Company can exercise significant influence over the investee, the investee is an associate of the Company. (2) Determination of initial investment cost ① Long-term equity investments formed through business combination For the long-term equity investment in the subsidiaries arising from business combination involving entities under common control, the initial investment cost of the long-term equity investment is the share with reference to the book value of the shareholders' equity of the combined party in the consolidated financial statements of the ultimate controlling party on the date of combination. The share premium in the capital reserve shall be adjusted according to the difference between the initial investment cost of the long-term equity investment and the carrying amount of the 258 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. consideration paid; if the share premium in the capital reserve is insufficient to offset, the retained earnings shall be adjusted. In connection with imposing control over the investee under common control as a result of additional investment and other reasons, the share premium shall be adjusted according to the difference between the initial investment cost of the long-term equity investment as recognized by the above principle and the carrying value of the long-term equity investment before combination and the sum of carrying value of newly paid consideration for additional shares acquired on the date of combination. If the share premium is insufficient for write-down, the retained earnings shall be offset. For the long-term equity investment in the subsidiaries arising from business combinations involving entities not under common control, the cost of the combination ascertained on the date of acquisition shall be taken as the initial investment cost of the long-term equity investment. In connection with imposing control over the investee not under common control as a result of additional investment and other reasons, the initial investment cost shall be the sum of the book value of the equity investment originally held and the newly increased initial investment cost. ② Long-term equity investments acquired by the means other than business combination The initial cost of a long-term equity investment obtained by cash payment shall be the purchase costs actually paid. The initial cost of investment of a long-term equity investment obtained by means of issuance of equity securities shall be the fair value of the equity securities issued. (3) Subsequent measurement and recognition of profit or loss ① Long-term equity investment calculated by cost method Long-term equity investment in subsidiaries of the Company is calculated by cost method, unless the investment meets the conditions for holding for sale. except for the actual consideration paid for the acquisition of investment or the declared but not yet distributed cash dividends or profits which are included in the consideration, investment gains are recognized as the Company' shares of the cash dividends or profits declared by the investee. ② Long-term equity investment accounted for by equity method Long-term equity investments of associates and joint ventures are calculated using equity method. Where the initial investment cost of the long-term equity investment exceeds the investor's interest in the fair value of the investee's identifiable net assets at the acquisition date, no adjustment shall be made to the initial investment cost; where the initial investment cost is less than the investor's interest in the fair value of the investee's identifiable net assets at the acquisition date, the difference shall be charged to the profit or loss for the current period. At the same time, the cost of the long-term equity investment shall be adjusted. The Company recognizes the investment income and other comprehensive income according to the shares of net profit or loss and other comprehensive income realized by the investee which it shall be entitled or shared respectively, and simultaneously makes adjustment to the book value of long-term equity investment; The book value of long-term equity investment shall be reduced by attributable share of the profit or cash dividends for distribution declared by the investee. In relation to other changes in the owner's equity except for net profits and losses, other comprehensive income and profit distributions of the investee (hereinafter referred to as “Changes in Other Owner's Equity”), the book value of the long-term equity investment shall be adjusted and included in owner's equity. 259 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. When determining the amount of proportion of net profit or loss, other comprehensive income and other changes in the owner's equity in the investee which it entitles, the fair value of each identifiable net assets of the investee at the time when the investment is obtained shall be used as basis, and according to the accounting policies and accounting period of the Company, adjustment shall be made to the net profit and other comprehensive income of the investee. The unrealized profit or loss resulting from transactions between the Company and its associates or joint venture shall be eliminated in proportion to the investor's equity interest of investee, based on which investment income or loss shall be recognized, except for those assets invested or sold constituting a business. Any losses resulting from transactions, which are attributable to impairment of assets, shall be fully recognized. The net loss incurred by the Company to the joint ventures or affiliates is capped when the carrying amount of long- term equity investment and the long-term equity that substantially constitutes the net investment in the joint ventures or affiliates have been wrote down to zero, except to the extent that the Company has an additional loss obligation. If the joint ventures or affiliates later realize net profit, the Company will resume recognition of the income share after the income share makes up the unrecognized loss share. ③ Disposal of long-term equity investments For disposal of long-term equity investment, the difference between the book value and the consideration actually received shall be included in the current profit or loss. If the remaining equity is still subject to the equity method in partial disposal of the long-term equity investment under the equity method, other comprehensive income recognized in the original equity investment shall be carried forward at the appropriate proportion on the same basis used by the investee for direct disposal of relevant assets or liabilities, and other changes in the owner's equity shall be carried forward into the current profit or loss at the appropriate proportion. When losing the control or material influence over the investee due to disposal of the equity investment and other reasons, other comprehensive income recognized in the original equity investment due to adoption of the equity method shall be subject to accounting treatment on the same basis used by the investee for direct disposal of relevant assets or liabilities when ceasing to use the equity method, and other changes in the owner's equity shall be carried forward into the current profit or loss in full when ceasing to use the equity method. If the control over the investee is lost due to partial disposal of the equity investment and other reasons, and if the remaining equities can exercise common control or material influence over the investee in preparing the individual financial statements, the remaining equities shall be accounted by the equity method and shall be adjusted as if such remaining equities have been accounted for under the equity method since they are obtained. Other comprehensive income recognized before the control over the investee is obtained shall be carried forward pro rata on the same basis used by the investee for direct disposal of relevant assets or liabilities, and other changes in the owner's equity recognized under the equity method shall be carried forward into the current profit or loss pro rata. The remaining equities which cannot exercise common control or material influence over the investee shall be recognized as financial assets, and the difference between their fair value and book value on the date when the control is lost shall be included in the current profit or loss. Other comprehensive income recognized and other changes in the owner's equity recognized before the control over the investee is obtained shall be carried forward in full. If the disposal of the equity investment in the subsidiaries through multiple transactions until loss of the control is a package deal, each transaction shall be subject to accounting treatment as a transaction to dispose of the equity 260 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. investment in the subsidiaries and to lose the control; the difference between the price for each disposal before loss of the control and the book value of the long-term equity investment of the equity disposed of shall be first recognized as other comprehensive income in the individual financial statements and shall then be carried forward to the profit or loss for the very period when the control is lost. If it is not a package deal, each transaction shall be subject to accounting treatment. 21. Investment properties Investment property refers to the real estate held to generate rental income or capital appreciation, or both, including leased land use rights, land use rights held for transfer after appreciation, and leased buildings (including buildings that are leased after completion of self-construction or development activities and buildings in construction or development that are used for rental in the future). The Company adopts the cost mode to measure the existing investment property. The subsequent expenditure related to the investment property will be included in the cost of the investment property when relevant economic benefits are likely to flow in and costs can be measured reliably, or otherwise be included in the current profit or loss when occurred. Investment property measured at cost - buildings held for leasing shall adopt the same depreciation policy for fixed assets of the company, land use rights held for leasing shall adopt the same amortization policy for the intangible assets. 22. Fixed assets (1) Conditions for recognition of fixed assets Fixed assets are tangible assets that are held for use in the production or supply of goods or services, for rental to others, or for administrative purposes; and have a service life of more than one fiscal year. Fixed asset is recognized when it meets the following conditions at the same time: ① It is probable that the economic benefits associated with the fixed asset will flow to the enterprise; ② Its cost can be reliably measured. The fixed assets are initially measured at cost (with the impact of predicted discard expense taken into account). The subsequent expenditure related to the fixed assets will be included in the cost of the fixed assets when the economic benefits in connection therewith are likely to flow in and costs can be measured reliably; the book value of the replaced part will be derecognized; all other subsequent expenditure will be included in the current profit or loss when occurred. (2) Methods for depreciation Useful lives of Annual depreciation Category Depreciation method Residual Ratio depreciation rate Housing and building Straight-line method 20 5% 4.75% Machinery and Straight-line method 5-10 5% 19.00%-9.50% equipment Means of transport Straight-line method 4-8 5% 23.75%-11.88% Electronic and other Straight-line method 3-5 5% 31.67%-19.00% equipment 261 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. Fixed assets are depreciated by categories using the straight-line method, and the annual depreciation rates are determined by categories based upon their estimated useful lives and their estimated residual values. Where the parts of a fixed asset have different useful lives or cause economic benefits for the enterprise in different ways, different depreciation rates or depreciation methods shall apply, and each part is depreciated separately. (3) Disposal of fixed assets When fixed assets are disposed of or when no economic benefits can be expected through use or disposal thereof, such fixed assets will be derecognized. The income from disposal of the fixed assets through sale, transfer, scrapping or damage with the book value thereof and relevant taxes deducted is included in the current profit or loss. 23. Projects under construction The projects under construction are measured at the actual cost. The actual cost comprises the building cost, installation cost, borrowing cost qualified for capitalization and other necessary expenditures incurred to bring the projects under construction to the conditions before they are made ready for the intended use. The projects under construction will be converted into fixed assets when they are ready for intended use and will be depreciated from the next month on. The criterion and time point for the projects under construction of the Company to be carried forward into fixed assets are shown as follows: Category Criterion and time point for carrying forward into fixed assets Housing and building When the housing and buildings meet the criteria for living by people after the completion acceptance and fire acceptance are completed and the water and power are available Machinery and equipment When the equipment is installed, commissioned and available for normal use Electronic and other equipment When the equipment is installed, commissioned and available for normal use 24. Borrowing costs (1) Criteria for recognition of capitalized borrowing costs For borrowing costs incurred by the Company that are directly attributable to the acquisition, construction or production of assets qualified for capitalization, the costs will be capitalized and included in the costs of the related assets. Other borrowing costs shall be recognized as expense in the period in which they are incurred and included in the profit or loss for the current period. Assets qualified for capitalization are assets (fixed assets, investment property, inventories, etc.) that necessarily take a substantial period of time for acquisition, construction or production to get ready for their intended use or sale. (2) Capitalization period of borrowing costs The capitalization period shall refer to the period between the commencement and the cessation of capitalization of borrowing costs, excluding the period in which capitalization of borrowing costs is suspended. Capitalization of borrowing costs begins when the following three conditions are fully satisfied: 262 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. ① Asset expenditures (including cash paid, transferred non-currency assets or expenditure for holding debt liability for the acquisition, construction or production of assets qualified for capitalization) have been incurred; ② Borrowing costs have been incurred; ③ The acquisition, construction or production necessary to enable the asset reach its intended state of serviceability or marketability have commenced. Capitalization of borrowing costs shall be suspended during periods in which the qualifying asset under acquisition and construction or production ready for the intended use or sale. (3) Suspension of capitalization period Capitalization of borrowing costs shall be suspended during periods in which the acquisition, construction or production of a qualifying asset is interrupted abnormally, when the interruption is for a continuous period of more than 3 months; if the interruption is a necessary step for making the qualifying asset under acquisition and construction or production ready for the intended use or sale, the capitalization of the borrowing costs shall continue. The borrowing costs incurred during such period shall be recognized as profits and losses of the current period. When the acquisition and construction or production of the asset resumes, the capitalization of borrowing costs commences. (4) Calculation of capitalization rate and amount of borrowing costs Specific borrowings for the acquisition, construction or production of assets qualified for capitalization, borrowing costs of the specific borrowings actually incurred in the current period minus the interest income earned on the unused borrowing loans as a deposit in the bank or as investment income earned from temporary investment will be used to determine the amount of borrowing costs for capitalization. General borrowings for the acquisition, construction or production of assets qualified for capitalization, the to-be- capitalized amount of interests on the general borrowing shall be calculated and determined by multiplying the weighted average asset disbursement of the part of the accumulative asset disbursements minus the specifically borrowed loans by the capitalization rate of the general borrowing used. The capitalization rate shall be calculated and determined according to the weighted average interest rate of the general borrowing. During the capitalization, the difference between the principal and interest of special borrowings in foreign currency shall be capitalized and included in the cost of assets qualified for capitalization. The difference between the principal and interest of the borrowings in foreign currency other than the special borrowings in foreign currency shall be included in the current profit or loss. 25. Intangible assets (1) Service life and its basis of determination, estimation, amortization method or review procedure ① Valuation method of intangible assets a. Intangible assets are initially measured at cost upon acquisition; The costs of an externally purchased intangible asset include the purchase price, relevant taxes and expenses paid, and other expenditures directly attributable to putting the asset into condition for its intended use. b. Subsequent measurement 263 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. The service life of intangible assets shall be analyzed and judged upon acquisition. As for intangible assets with a finite service life, they are amortized using the straight-line method over the term in which economic benefits are brought to the firm; If the term in which economic benefits are brought to the firm by an intangible asset cannot be estimated, the intangible asset shall be taken as an intangible asset with indefinite service life, and shall not be amortized. ② Estimation of service life of the intangible assets with limited service life Item Estimated useful lives Basis Land use rights 40 or 50 years Land use certificate Non-patented technology 5-10 years Expected benefited period Software 2-5 years Expected benefited period Trademark rights 6 years Expected benefited period Software copyright 10 years Expected benefited period For an intangible asset with a finite service life, review on its service life and amortization method is performed at the end of each end. Upon review, service life and amortization method for the intangible assets are the same with the previous estimate at the end of this period. ③ The basis for the judgment of intangible assets with uncertain service life and the procedure for reviewing their service life As at the balance sheet date, the Company has no intangible assets with uncertain service life. (2) Scope of accumulation and relevant accounting treatment method for R&D expenditures ① Scope of accumulation for R&D expenditures The expenditures incurred by the Company during the research and development include employee compensations of the personnel who are engaged in the R&D activities, costs of materials consumed, costs of depreciation and amortization and other relevant expenditures. ② Specific criteria for the division of research phase and development phase The expenses for internal research and development projects of the Company are divided into expenses in the research phase and expenses in the development phase. Research phase: Scheduled innovative investigations and research activities to obtain and understand scientific or technological knowledge. Development phase: Apply the research outcomes or other knowledge to a plan or design prior to a commercial production or use in order to produce new or essentially-improved materials, devices, products, etc. ③ Specific condition for capitalizing expenditure during the development phase Expenses in the research phase are recorded into the profits and losses for the current period when they occur. The expenses in the development phase are recognized as intangible assets if the following conditions are fulfilled, and are included in the current profit or loss if following conditions are not fulfilled: a. It is technically feasible to complete such intangible asset so that it will be available for use or for sale; b. There is intention to complete the intangible asset for use or sale; c. The ways in which intangible asset generates economic benefits, including there is evidence that the products produced using the intangible asset has a market or the intangible asset itself has a market; if the intangible asset is for internal use, there is evidence that there exists usage for the intangible asset; d. There is sufficient support in terms of technology, financial resources and other resources in order to complete the development of the intangible asset, and there is capability to use or sell the intangible asset; e. The expenses attributable to the development stage of the intangible asset can be measured reliably. 264 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. If the expenses in the research phase and expenses in the development phase cannot be distinguished, all the expenses incurred for R&D are included in the current profit or loss. 26. Impairment of long-term assets Long-term assets, such as long-term equity investment, investment properties that are measured at cost, fixed assets, construction in progress, intangible assets with limited service life and oil and gas assets are tested for impairment if there is any indication that an asset may be impaired at the balance sheet date. If the result of the impairment test indicates that the recoverable amount of the asset is less than its book value, a provision for impairment and an impairment loss are recognized for the amount by which the asset's book value exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less costs to sell and the present value of the future cash flows expected to be derived from the asset. Provision for asset impairment is determined and recognized on the individual asset basis. If it is not possible to estimate the recoverable amount of an individual asset, the recoverable amount of a group of assets to which the asset belongs to is determined. A group of assets is the smallest group of assets that is able to generate cash inflows independently. For the goodwill arising from business combination, intangible assets with uncertain service life, and intangible assets which are not ready for intended use, impairment test shall be conducted at least at the end of each year, regardless of whether there are signs of impairment or not. When the Company carry out impairment test to goodwill, the Company shall, as of the purchasing day, allocate on a reasonable basis the book value of the goodwill formed by merger of enterprises to the relevant asset groups, or if there is a difficulty in allocation, to allocate it to the sets of asset groups. Relevant asset groups or the sets of asset groups mean those can benefit from the synergy of business combination. For the purpose of impairment test on the relevant asset groups or the sets of asset groups containing goodwill, if any evidence shows that the impairment of asset groups or sets of asset groups related to goodwill is possible, an impairment test will be made first on the asset groups or sets of asset groups not containing goodwill, thus calculating the recoverable amount and comparing it with the relevant book value so as to recognize the corresponding impairment loss. An impairment test will be made on the asset groups or sets of asset groups containing goodwill to compare the book value of these asset groups or sets of asset groups with the recoverable amount. Where the recoverable amount is lower than the book value, the amount of impairment loss shall set off and be apportioned to the book value of the goodwill in the asset groups or sets of asset groups, and then set off the book value of other assets pro rata according to the proportion of the book value of other assets other than the goodwill in the asset groups or sets of asset groups. Once the above asset impairment loss is recognized, it will not be reversed in the subsequent accounting periods. 27. Long-term deferred expenses Long-term deferred expenses are expenses which have occurred but will benefit over 1 year and shall be amortized over the current period and subsequent periods. The amortization period and amortization method of various expenses are: Item Amortization Amortization period method Improvement expenditure of fixed assets leased by operating Straight-line By period of benefit lease method Renovation Cost Straight-line By period of benefit method 265 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. 28. Contract liabilities The Company lists contract assets or contract liabilities in the balance sheet according to the relationship between performance obligations and customer payments. The Company lists the obligation to transfer commodities or offer services to customers for the consideration received or receivable from customers as contract liabilities. The contract assets and contract liabilities under the same contract are presented in net amount. 29. Employee compensation (1) Accountant treatment of short-term remuneration During the accounting period when the staff provides service, the Company will recognize the short-term remuneration actually incurred as liabilities, and the liabilities would be charged into current profits and loss or costs of assets. The Company will pay social insurance and housing funds, and will make provision of trade union funds and staff education costs in accordance with the requirements. During the accounting period when the staff provides service, the Company will determine the relevant amount of employee benefits in accordance with the required provision basis and provision ratios. Employee compensation actually incurred by the Company will be included in the current profit or loss or relevant asset costs when actually incurred, in which non-monetary benefits will be measured at the fair value. (2) Accountant treatment of retirement benefit plan ① Defined contribution scheme The Company will pay basic pension insurance and unemployment insurance in accordance with the relevant provisions of the local government for the staff. During the accounting period when the staff provides service, the Company will calculate the amount payable in accordance with the local stipulated basis and proportions which will be recognized as liabilities, and the liabilities would be charged into current profits and loss or costs of assets. ② Defined benefit scheme The welfare responsibilities generated from defined benefit scheme based on the formula determined by projected unit credit method would be vested to the service period of the staff and charged into current profits and loss or costs of assets. (3) Accountant treatment of termination benefits If the dismissal welfare is provided by the Company to employees, the employee compensation liabilities arising from the dismissal welfare shall be determined at the earliest of the following two, and included in the current profits and losses: When the company cannot unilaterally withdraw the dismissal welfare provided due to the termination of labor relations plan or layoff proposal; When the company determines the costs or expenses associated with the restructuring involving the payment of dismissal welfare. 266 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. 30. Estimated liabilities The Company shall recognize the obligations related to contingencies as estimated liabilities, when all of the following conditions are satisfied: (1) The obligation is a present obligation of the Company; (2) It is probable that an outflow of economic benefits will be required to settle the obligation; (3) The amount of the obligation can be measured reliably. Estimated liabilities shall be initially measured at the best estimate of the expenditure required to settle the related present obligation. Factors pertaining to a contingency such as risk, uncertainties, and time value of money shall be taken into account as a whole in reaching the best estimate. Where the effect of the time value of money is material, the best estimate shall be determined by discounting the related future cash outflow. The expenses required have a successive range, in which the possibilities of occurrence of each result are the same, and the best estimate should be determined as the middle value for the range; in other circumstances, the best estimate will be handled as follows, respectively: (1) For the contingencies involving a single item, it will be determined according to the amount most likely to occur. (2) For the contingencies involving several items, it will be determined according to the possible results and the relevant possibilities. Where some or all of the expenditure required to settle an estimated liability is expected to be reimbursed by a third party, the reimbursement is separately recognized as an asset when it is virtually certain that the reimbursement will be received. The amount recognized for the reimbursement is limited to the book value of the estimated liability. The Company will review the book value of the estimated liabilities on the balance sheet date, and if there are concrete evidences that such book value cannot reflect the current best estimate, the book value will be adjusted according to the current best estimate. 31. Share-based payment The Company's share-based payment refers to a transaction in which an enterprise determines the liabilities on the basis of equity instruments granting or bearing for the acquisition of service from its employees or other parties. The Company's share-based payment is equity-settled. As to an equity-settled share-based payment in return for services of employees, calculation will be based on the fair value of the equity instrument granted to the employees. The share-based payment transactions vested immediately after the date of grant will be included in the relevant cost or expense based on the fair value of the equity instrument on the date of grant, and the capital reserve will be increased accordingly. For the services within the waiting period or the share-based payment transactions that may only be vested when the specified performance conditions are met after the date of grant, the Company will include the services obtained in the current period in relevant cost or expense and increase the capital reserve at the fair value on the date of grant according to the best estimate of the number of the exercisable equity instruments on each balance sheet date in the waiting period. If the terms of the equity-settled share-based payment are amended, the Company shall recognize the services received at least based on the situation before the amendment was made. In addition, any amendment resulting in the increase of the fair value of the equity instrument granted or changes that are beneficial to the staff on the amendment date, will be recognized as an increase in the service received. If the equity instruments vested are canceled during the waiting period, the Company will take the vested equity instruments canceled as accelerated exercise, and immediately include the amount to recognized during the waiting period in the current profit or loss. At the same time, the capital reserve will be recognized. However, if new equity 267 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. instruments are vested and they are verified at the vesting date of new equity instrument as alternatives vested to canceled equity instruments, the treatment on the new equity instrument is in conformity with the modified treatment on disposal of equity instrument. 32. Revenue (1) Accounting policies for revenue recognition and measurement If the Company performed the obligations in the contract, revenue shall be recognized when the customer acquires the right of control over relevant commodities or services. Acquisition of control over relevant commodities or services means gaining the ability to direct the use of such commodities or services and obtain nearly all the economic benefits therefrom. If the contract contains two or more performance obligations, the Company shall apportion the transaction price to each individual performance obligation on the contract commencement date according to the relative proportion of the individual selling price of the commodities or services promised by each individual performance obligation. The Company measures the revenue according to the transaction price apportioned to each individual performance obligation. The transaction price refers to the amount of consideration that the Company is expected to be entitled to collect due to the transfer of commodities or services to customers, excluding the payments collected on behalf of third parties and the payments expected to be returned to customers. The Company will determine the transaction price according to the contract provisions and its past practices, and may take into account the impact from the variable consideration, the major financing components in the contract, the non-cash consideration, the payable customer consideration and other factors when determining the transaction price. The Company shall determine the transaction price containing the variable consideration according to the amount not exceeding the amount by which the accumulative recognized revenue is much more unlikely to be significantly reversed when relevant uncertainties are eliminated. If there are major financing components in the contract, the Company shall determine the transaction price according to the amount due assumed to be paid in cash when the customer acquires the control over the commodities or services, and shall amortize the difference between such transaction price and the contract consideration using the effective interest rate method during the contract period. When one of the following conditions is met, it belongs to the performance obligation within a certain period of time, or otherwise it belongs to the performance obligation at a certain point of time: ① The customer acquires and consumes the economic benefits arising from the Company's performance while the company performs the contract; ② The customer can control the commodities in progress during the Company's performance; ③ The commodities produced by the Company during the performance possess irreplaceable usage, and the Company has the right to collect payment for the performance part accumulated so far during the whole contract period. For the performance obligations performed within a certain period of time, the Company shall recognize the revenue according to the performance progress within that period of time, except that the performance progress cannot be reasonably determined. The Company will determine the performance progress through the output or input method by taking into account the nature of commodities or services. If the performance progress cannot be reasonably recognized and the costs incurred are expected to be compensated, the Company will recognize the revenue according to the amount of costs incurred until the performance progress can be reasonably recognized. For the performance obligations performed at a certain point of time, the Company will recognize the revenue when the customer acquires the right of control over relevant commodities or services. While determining whether the customer has acquired the control over the commodities or services, the Company shall take the following into 268 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. consideration: ① The Company has the current collection right for the such commodities or services, that is, the customer has the current payment obligation for such commodities or services; ② The Company has transferred the legal title of such commodities to the customer, that is, the customer already has the legal title of such commodities; ③ The Company has transferred the physical commodities to the customer, that is, the customer has possessed the physical commodities; ④ The Company has transferred the major risks and rewards of the commodity title to the customer, that is, the customer has acquired the major risks and rewards of the commodity title; ⑤ The customer has accepted such commodities or services. The Company will judge whether it is a principal or agent at the time of transaction based on the fact as to whether the Company has the right of control over the commodities or services before such commodities or services are transferred to the clients. If the Company has control over the commodities or services before such commodities or services are transferred to the clients, the Company is a principal and the income is recognized by the total consideration received or receivable; or otherwise, the Company is an agent, and the income is recognized by the amount of commission or service charge that the Company is expected to be entitled to collect. (2) Recognition and measurement of the specific income disclosed per business type ① Principle for recognizing revenue from the domestic sales of standard products: The Company's security standard products are sold, through both direct sale and distribution, to the project clients, dealers and other customers. The Company and customers sign sales contracts and send the goods to customers according to the contractual terms of delivery, or the customers pick up goods. The revenue is recognized after the customer receives and accepts the goods and the Company obtains the evidence proving the client's receipt of goods; ② Principle for recognizing revenue from the overseas sales of standard products: If the domestic company makes direct export, the FOB and CIF terms are generally adopted and the Company recognizes the sale income after the product is declared and exported. If a foreign subsidiary sells the goods abroad, the goods will be sent to the customer or the customer will collect the goods according to the delivery method agreed with the customer, and the income will be recognized when the customer receives and accepts the goods; ③ Principle for recognizing system-integrated sales revenue: The sales of the system-integrated products of the Company include providing the supporting services such as plan design, supporting products, installation, debugging and system trial operation. The sales income will be recognized upon acceptance; ④ Principle for recognizing the income from labor services: The income is recognized when the labor service is provided. 33. Contract costs The contract costs comprise the contract performance cost and the cost to obtain a contract. The costs incurred by the Company for contract performance which fall outside the scope of the enterprise accounting standards such as inventories, fixed assets or intangible assets will be identified as an asset of the contract performance costs upon satisfying all of the following conditions: (1) The costs are directly related to one existing contract or one contract that is expected to be obtained; (2) The costs enrich the Company's resources for future contract performance; 269 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (3) The costs are estimated to be recovered. The incremental costs which are incurred by the Company to obtain the contract and are expected to be recovered will be identified as an asset of the costs to obtain a contract. The assets related to the contract costs will be amortized on the same basis for recognition of the income from commodities or services related to the assets; but if the amortization period of the costs to obtain the contract is no more than 1 year, the Company will include such costs in the current profit or loss once occurred. In case that the book value of assets related to contract costs is higher than the difference between the two items below, the Company will accrue the impairment provision for the extra part, and recognize that part as impairment loss: (1) Estimated residual consideration to be obtained from transfer of commodities or services related to the assets; (2) Estimated costs incurred from transfer of relevant commodities or services. If the factors for impairment in the previous periods are subsequently changed, making the aforesaid difference higher than the book value of the assets, the Company will reverse the accrued impairment provision and include it in the current profit or loss, provided that the book value of the reversed assets does not exceed the book value of the assets without impairment provision accrued on such date of reversal. 34. Government subsidies (1) Type Government grants are monetary assets and non-monetary assets acquired by the Company from the government free of charge. Government grants are classified into government grants related to assets and government grants related to revenue. Government grants related to assets refer to government grants acquired by the Company for the purpose of purchasing or constructing or otherwise forming long-term assets. Government grants related to revenue refer to the government grants other than those related to assets. (2) Confirmation of time point Government grants related to assets will be measured at the actual amount of money received at the time of receipt. The assets (bank deposits) and deferred income shall be period by period included in the profits and losses of the current period in a reasonable and systematic manner from the time the assets are available for use (those related to the Company's daily activities shall be included in other income; those unrelated to the Company's daily activities shall be recognized as non-operating revenue). When the relevant assets are disposed of (sold, transferred, scrapped, etc.) at or before the end of their service life, the balance of the deferred income that has not yet been apportioned will be transferred to the current-period income from the disposal of the assets on an one-time manner, and will not be deferred. For government grants related to revenue, they will be recognized as profit and loss of the current period according to the amount receivable for government grants obtained under fixed quota standards, otherwise, they will be recognized as profit and loss of the current period when it is actually received. (3) Accounting treatment Government grants related to assets shall write off the book value of relevant assets or be recognized as deferred income. When recognized as deferred income, the government grant related to assets will be period by period credited 270 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. to the profits and losses of the current period in a reasonable and systematic manner within the service life of relevant assets (those related to the Company's daily activities shall be recognized as other income; those unrelated to the Company's daily activities shall be recognized as non-operating revenue). The revenue-related government grants shall be recognized as deferred income if they are used to compensate relevant expenses or losses in subsequent periods, and they shall be included in profit and loss of the current period (those related to Company's routine activities shall be included in other income; those unrelated to the Company's routine activities shall be included in non-operating revenue) or used to offset relevant expenses or losses during the recognition of related expenses or losses; the grants used to compensate related expenses or losses incurred shall be included in profit and loss of the current period (those related to Company's routine activities shall be included in other income; those unrelated to the Company's routine activities shall be included in non-operating revenue) or used to offset relevant expenses or losses. The policy-oriented concessional loan discount interests obtained by the Company will be subject to accounting treatment in the following two circumstances: ① Where the finance allocates the discount interest funds to the lending bank, and the lending bank provides loans to the Company at the policy preferential interest rate, the Company will take the actually received loan amount as the entry value of the loan, and the relevant borrowing costs shall be calculated according to the loan principal and the policy preferential interest rate; ② If the finance directly allocates the discount interest funds to the Company, the Company shall set off the corresponding discount interest against the relevant borrowing costs. 35. Deferred income tax assets / deferred income tax liabilities Income tax comprises current income tax and deferred income tax. Except for the income taxes arising from the business combination and the transactions or matters that are directly included in the owner's equity (including other comprehensive income), the Company will include the current income tax and deferred income tax into the current profit or loss. Deferred income tax assets and deferred income tax liabilities will be calculated and recognized according to the difference (temporary difference) between the tax basis and the book value of assets and liabilities. Deferred income tax assets are recognized to the extent that it is probable that future taxable income will be available against which deductible temporary differences can be utilized. For deductible losses and tax credits that can be reversed in the future period, deferred income tax assets shall be recognized to the extent that it is probable that taxable income will be available in the future to offset the deductible losses and tax credits. Save as the exceptions, deferred income tax liabilities shall be recognized for the taxable temporary difference. The exceptions where deferred income tax assets and liabilities are not recognized include: (1) Initial recognition of the goodwill; (2) Transactions or events that are neither business combinations nor affect profit and taxable income (or deductible loss) when occurring. Taxable temporary difference related to investment in the subsidiaries, affiliates and joint ventures will be recognized as deferred income tax liabilities, unless the Company can control the time to reverse such temporary difference and such temporary difference is much more unlikely to be reversed in the predictable future. Deductible temporary difference related to investment in the subsidiaries, affiliates and joint ventures will be recognized as deferred income tax assets when such temporary difference is much more likely to be reversed in the predictable future and is much more likely to be obtained to deduct the taxable income of the deductible temporary difference. 271 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. On the balance sheet date, the deferred income tax assets and the deferred income tax liabilities will be measured at the tax rate applicable during the recovery of relevant assets or payment of relevant liabilities as expected according to the provisions of the tax law. On the balance sheet date, the Company will review the book value of the deferred income tax assets. If no sufficient taxable income is likely to be obtained to offset the benefits of deferred income tax assets in the future, the book value of deferred income tax assets shall be written down. The amount written down shall be reversed when it is likely to obtain sufficient taxable income. After granted the legal rights of net settlement and with the intention to use net settlement or obtain assets and repay debt at the same time, the net amount after offsetting its current income tax assets and current income tax liabilities shall be recorded. On the balance sheet date, the deferred income tax assets and the deferred income tax liabilities will be presented by the net amount after offsetting when the following conditions are fulfilled: (1) The taxpayer is granted the legal rights to settle current income tax assets and current income tax liabilities on a net basis; (2) Deferred income tax assets and deferred income tax liabilities are related to income tax to be paid by the same entity liable for paying tax to the same tax collection and management authority or related to different entities liable for paying tax, but the relevant entity liable for paying tax is intended to apply net settlement of current income tax assets and liabilities or, at the same time, obtain assets, repay debt whenever every deferred income tax assets and liabilities with importance would be reversed in the future. 36. Lease Lease means the contract by which the lessor transfers the right to use the assets to the lessee for a given period to obtain the consideration. On the commencement of the contract, the Company will assess whether the contract is a lease or contains the lease. If a party to the contract conveys the right to control the use of one or more identified assets for a given period to obtain a consideration, this contract is a lease or contains the lease. If a contract contains several individual leases, the Company will split the contract and conduct accounting treatment of each individual lease separately. If a contact contains both lease and non-lease, the lessee and the lessor will split the lease and non-lease parts. If all the following conditions are met, the Company will simplify all the lease options without assessing whether the lease is changed or reassessing the lease classification: (1) The lease consideration after reduction is less or remains substantially the same compared with the lease consideration before reduction, and the lease consideration may either be undiscounted or discounted by the discount rate before reduction; (2) Other terms and conditions of lease are identified without significant change after taking the qualitative and quantitative factors into full account. (1) The Company as a lessee ① Right-of-use assets The Company recognizes the right-to-use assets for the lease other than short-term lease and low-value asset lease on the commencement of the lease term. The right-to-use assets are initially measured at cost which includes: a. Initial measurement amount of lease liabilities; b. For the lease payment paid on or before the commencement of the lease term, if there are lease incentives, the relevant amount of lease incentives enjoyed shall be deducted; 272 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. c. Initial direct cost incurred by the Company; d. The estimated costs incurred by the Company for dismantling and removing the leased asset, restoring the site where the leased asset is located or restoring the leased asset to the state agreed in the lease terms, but excluding the cost incurred to produce the inventory. The Company will depreciate the right-to-use assets through the straight-line method. If it can be reasonably recognized that the title of the leased asset is acquired at the expiration of the lease term, the Company shall accrue depreciation within the remaining service life of the leased asset; or otherwise, the leased asset shall be depreciated within the shorter of the lease term and the remaining service life of the leased asset. The Company will determine whether the right-of-use assets are impaired and conduct accounting treatment over the identified impairment loss according to the principles set out in this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 26. Impairment of long-term assets. ② Lease liabilities The Company recognizes the lease liabilities for the lease other than short-term lease and low-value asset lease on the commencement of the lease term. Lease liabilities shall be initially measured at the present value of the unpaid lease payments. Lease payments include: a. Fixed payment (including actual fixed payment), deducting lease incentives (if any); b. Variable lease payment depending on the index or ratio; c. Predicted payment on the basis of the guaranteed residual value provided by the Company; d. Exercise price of the call option, provided that the Company will exercise such option, as reasonably determined; e. Payment for exercise of the lease termination option, provided that the lease term reflects the Company’s future exercise of the lease termination option. The interest rate implicit in lease is applied by the Company as the discount rate. If the interest rate implicit in lease cannot be reasonably determined, the Company's interest rate on incremental borrowings is applied as the discount rate. The Company shall calculate the interest expense of the lease liabilities during each period of the lease term at a fixed periodic interest rate and include it in the current profit or loss or relevant asset cost. The variable lease payment which is not included in the measurement of lease liabilities shall be included in the current profit or loss or relevant asset cost when actually incurred. If any of the following circumstances happens on commencement of the lease term, the Company will remeasure the lease liabilities and adjust the corresponding right-of-use assets, and if the book value of the right-of-use assets has been reduced to zero, but the lease liabilities still need to be further reduced, the difference shall be included in the current profit or loss: a. When the assessment result of the call option, renewal option or termination option is changed or the actual exercise of the aforesaid option is inconsistent with the original assessment result, and the Company remeasures the lease liabilities at the present value worked out according to the changed lease payment and the revised discount rate; b. When there are changes in the actual fixed payment, the estimated payable amount of guaranteed residual value, or the index or ratio applied to determine the amount of lease payments, the Company remeasures the lease liabilities at the present value worked out according to the changed lease payment and the original discount rate. If the change in the lease payment originates from the change in the floating interest rate, the present value will be calculated using the revised discount rate. ③ Short-term lease and low-value asset lease The Company chooses not to recognize the right-of-use assets and lease liabilities for the short-term lease and low- value asset lease, and records relevant lease payment into the current profit or loss or relevant asset cost according to the straight-line method in each period of the lease term. Short-term lease means the lease of no more than 12 273 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. months and excluding the call option on the commencement of the lease term. Low-value asset lease means a lease of lower value when the single leased asset is brand-new. If the Company sublets or is expected to sublet the leased assets, the original lease is not a low-value asset lease. ④ Lease change If the lease is changed and meets all of the following conditions, the Company will conduct accounting treatment with respect to such lease change as a single lease: a. Such lease change has expanded the scope of lease by adding the right to use one or more leased assets; b. The increased consideration is equivalent to the amount of the separate consideration for the expanded part of the scope of lease adjusted according to this contract. If the lease change is not taken as a separate lease for accounting treatment, on the effective date of the lease change, the Company will re-apportion the consideration of the changed contract, re-determine the lease term, and remeasure the lease liabilities at the present value worked out according to the changed lease payment and the revised discount rate. If the lease change results in narrower scope of lease or shorter lease term, the Company will reduce the book value of the right-of-use assets accordingly, and will include relevant gain or loss from partial or full termination of the lease in the current profit or loss. If other lease changes result in re-measurement of the lease liabilities, the Company will adjust the book value of the right-to-use assets accordingly. (2) The Company as a lessor On commencement of the lease term, the Company will divide the lease into financial lease and operating lease. Financial lease means the lease that has substantially transferred almost all the risks and rewards related to the title of the leased assets, whether or not the title will be finally transferred. Operating lease means any lease other than financial lease. When the Company serves as a lessor of the sublease, the sublease will be classified on the basis of the right-to-use assets resulting from the original lease. ① Accounting treatment of operating lease The lease receipts for the operating lease will be recognized as the rental income according to the straight-line method during each period of the lease term. The initial direct fee related to the operating lease to be incurred by the Company will be capitalized and will be apportioned and included in the current profit or loss on the same basis as that for recognition of the rental income in the lease term. The variable lease payments that are not included in the lease receipts shall be included in the current profit or loss when they actually occur. In case of a change to the operating lease, the Company will conduct accounting treatment with respect to the changed operating lease as a new lease as of the effective date of the change, and the lease payments received in advance or receivable with respect to the lease before the change will be taken as the lease receipts for the new lease. ② Accounting treatment of financial lease On the commencement of the lease term, the Company will recognize the financial lease receivables for the financial lease, and derecognize the financial lease assets. The Company will take the net lease investment as the entry value of the financial lease receivables when initially measuring the financial lease receivables. The net lease investment is the sum of the unguaranteed residual value and the present value of the unreceived lease receipts discounted according to the interest rate implicit in lease on the commencement of the lease term. The Company will calculate and recognize the interest income during each period of the lease term at a fixed periodic interest rate. The derecognition and impairment of the financial lease receivables will be subject to accounting treatment according to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments. 274 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. The variable lease payments that are not included in the measurement of the net lease investment shall be included in the current profit or loss when they actually occur. If the financial lease is changed and meets all of the following conditions, the Company will conduct accounting treatment with respect to such change as a single lease: a. Such change has expanded the scope of lease by adding the right to use one or more leased assets; b. The increased consideration is equivalent to the amount of the separate consideration for the expanded part of the scope of lease adjusted according to this contract. If the change in the financial lease is not subject to accounting treatment as a single lease, the Company will treat the changed lease in the following circumstances: a. If the change takes effect on commencement of the lease term and the lease is classified as operating lease, the Company will conduct accounting treatment with respect to such lease as a new lease as of the effective date of the lease change, and will take the net lease investment before the effective date of the lease change as the book value of the leased asset; b. If the change takes effect on the commencement date of the lease, and such lease is classified as the financial lease, the Company will conduct accounting treatment according to the policy regarding modification or re-negotiation of the contract in this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments. (3) Sale and leaseback transaction The Company evaluates and determines whether the asset transfer in the sale and leaseback transaction belongs to a sale in accordance with the provisions of this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 32. Income. ① Acting as a lessee If the asset transfer in the sale and leaseback transaction is a sale, the Company as the lessee shall measure the right-of-use asset arising from the sale and leaseback according to the part related to the right of use acquired from the leaseback in the original book value of the asset, and only recognize relevant gain or loss on the rights transferred to the lessor; if the asset transfer in the sale and leaseback transaction is not a sale, the Company as the lessee shall continue to recognize the transferred asset, and recognize a financial liability equal to the transfer income. For accounting treatment of the financial liabilities, refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments. ② Acting as a lessor If the asset transfer in the sale and leaseback transaction is a sale, the Company as the lessee shall conduct accounting treatment with respect to the asset purchase and conduct accounting treatment with respect to the asset lease according to the policy in the foregoing "(2) The Company as a lessor"; if the asset transfer in the sale and leaseback transaction is not a sale, the Company as the lessor shall derecognize the transferred asset, but recognize a financial asset equal to the transfer income. For accounting treatment of the financial assets, refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments. 275 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. 37. Other significant accounting policies and accounting estimates (1) Repurchase of the Company's shares The Company's shares repurchased by the Company for reducing the registered capital or rewarding employees shall be treated as the treasury shares based on the actual amount paid, and shall be checked and registered at the same time. If the repurchased shares are canceled, the difference between the actual amount paid for the repurchase and the total par value of shares calculated based on the par value of the canceled shares and the number of canceled shares will be set off against the capital reserve. If the capital reserve is insufficient, the retained earnings will be written off; if the repurchased shares are awarded to the employees of the Company, it shall be categorized as equity- settled share-based payment. When the Company receives the payment made by employees who exercise their rights to purchase such shares, the amount shall be used to write off the cost of treasury shares delivered to employees and the capital reserve in the waiting period and meanwhile, the capital reserve (stock premium) shall be adjusted according to the difference. (2) Debt restructuring ① The Company as a creditor The Company will derecoginize the creditor's rights when its contractual right to collect the cash flow for the creditor's rights is terminated. If the debts are restructured by repaying the debts with assets or converting the debts into equity interments, the Company will recognize relevant assets within the meaning of their definitions and recognition conditions. If the debts are restructured by repaying the debts with assets, when initially recognized by the Company for acceptance, the non-financial assets will be measured at cost. The costs of inventories include the fair value of the creditor's rights abandoned and the taxes, transportation costs, handling charges, insurance premiums and other costs directly attributable to such assets, which are incurred to realize the current position and state of such assets. The costs of investments in the associates or joint ventures include the fair value of the creditor's rights abandoned and the taxes and other costs directly attributable to such assets. The costs of investment properties include the fair value of the creditor's rights abandoned and the taxes and other costs directly attributable to such assets.

The costs of biological assets include the fair value of the creditor's rights abandoned and the taxes, transportation costs, insurance premiums and other costs directly attributable to such assets. The costs of intangible assets include the fair value of the creditor's rights abandoned and the taxes and other costs directly attributable to such assets, which are incurred for such assets to become ready for their intended use. If the creditor converts its creditor’s rights into equity investments in the associates or joint ventures arising from the debt restructuring by converting the debts into equity instruments, the Company will measure its initial investment cost according to the fair value of the creditor's rights abandoned and the taxes and other costs directly attributable to such assets. The difference between the fair value and the book value of the creditor’s rights abandoned shall be included in the current profit or loss. 276 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. If the debts are restructured by modifying other terms, the Company will recognize and measure creditor’s rights restructured according to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments. If the debts are restructured by repaying the debts with several assets or through combination, the Company will first recognize and measure the financial assets accepted and creditor’s rights restructured according to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 11. Financial instruments, then distribute the net amount derived from deducting the recognized amount of the financial assets accepted and creditor’s rights restructured from the fair value of the creditor’s rights abandoned according to the proportion of the fair value of the assets other than the financial assets accepted, and on this basis, determine the costs of various assets respectively by the aforesaid means. The difference between the fair value and the book value of the creditor’s rights abandoned shall be included in the current profit or loss. ② The Company as a debtor The Company will derecognize the debts when the current obligation under the debts is discharged. If the debts are restructured by repaying the debts with assets, the Company will derecognize relevant assets and the debts repaid within the meaning of their derecognition conditions, and the difference between the book value of the debts repaid and the book value of the assets transferred shall be included in the current profit or loss. If the debts are restructured by converting the debts into equity interments, the Company will derecognize the debts repaid within the meaning of their derecognition conditions. When initially recognized by the Company, the equity instruments will be measured at its fair value, and if the fair value of the equity instruments cannot be reliably measured, at the fair value of the debts repaid. The difference between the book value of the debts repaid and the recognized amount of the equity instruments shall be included in the current profit or loss. If the debts are restructured by modifying other terms, the Company will recognize and measure the debts restructured according to this section Financial Report - V.

After the change, the Company directly holds 78% equity in Hangzhou Xiaohua Technology Co., Ltd. and exercises the voting rights according to its equity ratio. 341 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (2) Based on the industrial and commercial registration data, the CDB Development Fund holds equity in the Company. According to the cooperation agreement between the Company and CDB Development Fund, CDB Development Fund shall not appoint senior management personnel, such as directors and supervisors, to Dahua Zhilian; regarding its investment, the Company shall pay an annual investment profit of 1.2% to CDB Development Fund through dividends, repurchase premiums, etc. In addition, the Company shall redeem the CDB Development Fund's equity in Dahua Zhilian period by period from 2022 to 2024, using its amount of investment as other non-current liabilities, and reclassifying those due within one year to "non-current liabilities due within one year".

After the dilution of equity, the Company is still the largest shareholder of HuaRay Technology. The remaining shareholders have a low and dispersed shareholding ratio, and HuaRay Technology is still a holding subsidiary of the Company, and is included the scope of consolidation of the Company. (5) In August 2023, the Company acquired 15.00% equity in Huafei Intelligent held by Hangzhou Hua’ao Enterprise Management Partnership (Limited Partnership) with a consideration of RMB 13,347,000. After the acquisition of equity, the Company’s original 45.50% equity in Huafei Intelligent was increased to 60.50%, and after the change, the Company exercises the voting rights according to its equity ratio. (6) The Company directly holds 45% equity in Zhejiang Huajian Technology Co., Ltd., and as agreed upon, Ningbo Hualing Venture Capital Investment Partnership (Limited Partnership) grants its voting rights of 35% to the Company.

Risks Relating to Financial Instruments 1. Risks arising from the financial instruments In the business operation, the Company is facing with various financial risks: credit risk, liquidity risk and market risk (including exchange rate risk, interest rate risk and other price risks). The overall objective of the Company's risk management is to formulate risk management policies that can minimize risks without affecting the Company's competitiveness and adaptability to changes too much. (I) Credit risk The credit risk refers to the risk of financial loss to the Company as a result of a counterparty's failure to fulfill its contractual obligations. The Company is mainly facing with the customer credit risk arising from sales on account. Before signing a new contract, the Company will assess the new customer's credit risk, including external credit rating and the credibility letter from a bank under some circumstances (if such information is available). The Company has set a credit limit for sales on account for each customer. Such limit shall be the maximum amount with no additional approval needed. The Company ensures that the overall credit risk is within the controllable range through quarterly monitoring of credit ratings of existing customers, and monthly review of aging analysis on accounts receivable. When monitoring customers' credit risk, the Company groups them according to their credit characteristics. Customers rated as "high risk" will be placed on the restricted customer list. The Company can provide them with O/A in the future period only when additional approval is obtained. Otherwise they must make relevant payment in advance. 345 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. For overseas customers, the Company mainly uses wire transfer as a payment method. According to the credit evaluation of each customer, the Company gives different credit lines and credit account periods, and agrees on the payment method and account period in the commodity procurement contract between the two parties. After the sales of products, the Company has a dedicated person responsible for tracking, reconciliation, and payment reminding. In addition, the Company introduced export credit insurance to ensure that the return risk from overseas customers is within controllable range. (II) Liquidity risk Liquidity risk refers to the risk of a shortage of funds when an enterprise fulfills its obligation of settlement by cash or other financial assets. The Company's policy is to ensure that there is sufficient cash to repay the liabilities due. The liquidity risk is under the concentrated control of the Company's Financial Department. Through monitoring the balance of cash and securities cashable at any time and rolling forecasting the cash flow in the next 12 months, the Financial Department ensures that the Company has sufficient funds to repay its debts under all reasonable predictions. The financial liabilities of the Company are listed as follows based on the undiscounted contractual cash flow: Unit: RMB December 31, 2023 Item Within 1 year 1 years or above Total Short-term 961,559,707.96 961,559,707.96 loan Notes 3,296,294,946.26 3,296,294,946.26 Payable Accounts 5,815,123,195.55 5,815,123,195.55 Payable Other 812,424,146.52 812,424,146.52 Payables Non-current Liabilities Due 924,321,195.99 924,321,195.99 within 1 Year Long-term loan Lease 187,049,189.60 187,049,189.60 Liabilities 11,809,723,192.28 187,049,189.60 11,996,772,381.88 Total December 31, 2022 Item Within 1 year 1 years or above Total Short-term loan 260,776,817.68 260,776,817.68 Notes Payable 4,364,097,761.17 4,364,097,761.17 Accounts Payable 7,340,277,388.29 7,340,277,388.29 Other Payables 1,004,056,999.91 1,004,056,999.91 Non-current Liabilities 2,612,356,720.16 2,612,356,720.16 Due within 1 Year Long-term loan 12,189,009.07 460,171,666.67 472,360,675.74 Lease Liabilities 209,266,176.61 209,266,176.61 Total 15,593,754,696.28 669,437,843.28 16,263,192,539.56 346 2023 Annual Report of Zhejiang Dahua Technology Co., Ltd. (III) Market Risk The market risk of financial instruments refers to the risk of fluctuation at fair value of financial instruments or future cash flows with the change of market prices, including exchange rate risks, interest rate risks and other price risks. 1. Interest rate risk The interest rate risk refers to the risk in which the fair value or future cash flow of financial instruments changes due to the change of market interest rate. The interest rate risk faced with by the Company is mainly from bank loans. The Company's assets and liabilities relating to interest rate are respectively bank deposits and short-term loans, whose interest rate risk is low. 2. Exchange rate risk The exchange rate risk refers to the risk in which the fair value or future cash flow of financial instruments changes due to the change of foreign exchange rate. The Company will try its best to match the revenues with the expenses in foreign currency, to lower the exchange rate risk. In addition, the Company may also sign forward foreign exchange contracts or currency swap contracts to avoid exchange rate risks. The exchange rate risk faced with by the Company is mainly from financial assets and liabilities in USD.
