MANAGEMENT/CHAIRMAN'S MESSAGE

Over the past year, as the "Dual Carbon" goals have advanced, the global green transition has continued to deepen. The energy and chemical industry has concurrently faced both challenges and opportunities arising from cyclical fluctuations and structural transformation. Adhering to its mission of "Better Technology, Better Future", Wilson Engineering has been driven by the dual engines of "Technology Leadership and Globalisation". While consolidating its strengths in traditional core business, the Company is accelerating its expansion into green, low-carbon, and high-value-added sectors, thereby creating sustainable, long-term value for its clients and society at large.

During the Year, leveraging the opportunities from our strong push for "International Transformation" and the execution of overseas projects with high health, safety, and environment ("QHSE") standards, we have continuously strengthened our quality, QHSE management. With our engineering services directed towards green carbon reduction and new energy development, we strive to provide customers with higher-quality products and services, while ensuring the safety and occupational health of all personnel and implementing measures for green environmental protection, energy conservation, and carbon reduction.

COMPREHENSIVE QHSE ENHANCEMENT AND CONSOLIDATION OF HIGH-QUALITY DELIVERY

In 2025, the Company achieved a cumulative total of 22.82 million safe man-hours across all domestic and international projects. There were zero Lost Time Injuries (LTI) or more severe incidents, no environmental pollution incidents, and no occupational health events. All key quality management indicators not only met but exceeded the targets set at the beginning of the year. Multiple projects achieved successful start-up on the first feed, earning high recognition from clients and receiving industry accolades. Guangxi Huayi MTO project department was awarded the "Outstanding Monthly Work Safety Team" by the client 8 times during the Year. These accomplishments fully highlighted the Company's QHSE management capabilities and maturity throughout the project execution process.

TECHNOLOGICAL INNOVATION AND GREEN TRANSITION

In addition to maintaining our focus on core businesses and competitive strengths while advancing our international transformation to consolidate our market leadership, we are comprehensively accelerating our green transition. We are scaling up investments in new energy technologies and have achieved continuous progress in emerging sectors such as degradable plastics (PGA), methyl methacrylate (MMA), carbon emission reduction, and green methanol and ammonia. These efforts actively drive the upgrading of our international development and new energy transformation.

MANAGEMENT/CHAIRMAN'S MESSAGE

We remained committed to technological expansion and industry collaboration within the new energy sector. In partnership with our collaborators, we launched MegaFlex, a comprehensive, one-stop solution for large-scale green hydrogen production. Embracing the "Plant-as-a-Product" philosophy, we promoted the standardization, modularization, and rapid deployment of hydrogen production stations. Furthermore, we have established demonstration and industrial synergy effects in key areas including carbon capture, utilisation and storage (CCUS), green ammonia, and green methanol. During the Reporting Period, the Green Chemical Demonstration Project for Methanol Production via $\mathrm{CO}_{2}$ Capture at Shanghai Waigaoqiao No. 3 Power Plant successfully passed performance tests, meeting leading benchmarks. This project was also honoured as a "Landmark (Typical) Project of the 40th Anniversary of Shanghai's Exploration & Design Industry."

COMPLIANCE AND GOVERNANCE

At the governance level, the Board of Directors directly oversees ESG governance, approving ESG and climate strategies. The Social Responsibility Executive Committee is responsible for identifying ESG and climate-related material issues and risks, as well as coordinating ESG and climate management and disclosure. This three-tier governance structure ensures the implementation of ESG and climate strategies and drives continuous improvement. During the Year, we further optimised our supplier access system by establishing green bidding and procurement indicators. We incorporated additional requirements for HSE, low-carbon standards, and green certifications, enabling a comprehensive assessment of supplier green performance.

GREEN, LOW-CARBON, AND CLIMATE ACTIONS

We have completed our greenhouse gas verification, and incorporated Scope 3 into our inventory boundary, continuously optimising our emission reduction pathways and operational decisions in a data-driven manner. Following the achievement of China's first ISO 14064-1:2018 Greenhouse Gas Verification Statement Certificate covering the entire value chain in the petrochemical engineering industry during the first half of the year, we were also awarded the "Energy Enterprise Sustainable Development (ESG) Evaluation Certificate" at the 2nd International Forum on Energy and Sustainable Development (ESG). These accomplishments fully underscored Wison Engineering's commitment to green development as an industry leader. At our ongoing project sites, we continued to implement "Green Construction" with a focus on the "Four Savings" (materials, land, water, and electricity). By leveraging the OA system for online ESG data reporting, we standardized data management and ensured the implementation of ESG requirements at the project sites. Furthermore, through organizing "Low-Carbon Environmental Protection and Green Travel" campaigns for World Environment Day, we continued to enhance employee awareness regarding low-carbon environmental protection.

Development Context

Wison Engineering was incorporated in Shanghai in 1997 and its development has gone through four phases. In the first phase (1997–2004), we gradually established our core competence in ethylene cracker technology and project management, and secured our first ethylene cracker revamp contract. In the second phase (2005–2008), we obtained multiple relevant qualifications in the petrochemical field and developed our EPC general contracting capability for complete plants. In the third phase (2008–2017), we established a leading position in the coal chemical market, expanded into overseas markets, and were successfully listed in Hong Kong in 2012. The Group is now in the fourth phase (since 2018), accelerating our global presence, expanding into the Southeast Asian market, and focusing on the flagship market of the Middle East, establishing close cooperation with national oil giants in countries such as Saudi Arabia, the UAE, and Qatar.

As of 31 December 2025, the Group’s business has expanded to regions including Southeast Asia, the Middle East, Africa, North America, and South America. The business scope covers the storage and utilisation of basic energy resources such as coal, oil and natural gas, including onshore energy engineering services, and the development of downstream chemical new materials, and keeps moving towards becoming a world-class energy and chemical engineering company.

1.2 GOVERNANCE STRUCTURE

Wison Engineering deeply recognizes that a sound system and governance structure is the core of the Company's steady development. To this end, we strictly adhere to the requirements of relevant laws and regulations such as the Laws of the People's Republic of China and the Corporate Governance Code in Appendix C1 to the Listing Rules, continuously strengthening our internal governance mechanisms to ensure our operations are standardised, transparent, and compliant.

Wison Engineering Services Co. Ltd.
Environmental, Social and Governance Report 2025

In terms of governance structure, our Group has established a management system with the Board of Directors at its core, under which a Nomination Committee, an Audit Committee, and a Remuneration Committee are set up, with their respective functions and authorities clearly defined. Each committee undertakes key responsibilities such as risk management, internal control supervision, compliance review, and remuneration management, working together with the Board of Directors to promote the efficient operation of corporate governance. These governance arrangements have significantly improved the transparency and enforceability of corporate management, providing a solid institutional guarantee for the Group's long-term value creation.

Risk Management

The Group deeply understands that a sound risk management system is the key to achieving long-term sustainable development. In accordance with the Enterprise Risk Management — Integrating with Strategy and Performance issued by the Committee of Sponsoring Organisations of the Treadway Commission (COSO), we have formulated internal systems such as the Risk Management Manual, the Provisions on Risk Management in the Preliminary Stage of Engineering Projects, and the Risk Management Procedures for Engineering Project Implementation. Based on long-term practical experience, we have gradually established a risk management database, forming a systematic risk management framework that covers the Group's entire business fields and runs through the whole process of risk identification, assessment, control, and monitoring, thereby evaluating risk levels and safeguarding the rights and interests of all parties. As internal systems become increasingly sound, we are also able to apply risk control mechanisms to various daily operations more efficiently.

At the governance structure level, the Group has formed a Risk Management Working Group composed of three Independent Non-executive Directors, who are specifically responsible for supervising the implementation of risk management and internal control systems, and regularly providing professional advice to the Board of Directors. Meanwhile, management and various business departments cooperate with the Board to advance risk management, continuously improving the overall risk management effectiveness of the Group through regular and ad hoc risk identification, assessment, response, and follow-up.

In addition, upon completion of risk treatment, we also conduct a review and evaluation of the entire process, report the assessment conclusions to the Board of Directors, and implement corresponding preventive or remedial measures accordingly, so as to reduce potential losses at the source, ensure the steady operation of the Company, and escort the development of the enterprise.

Risk Management Checklist

Operation with Integrity

Wison Engineering attaches great importance to maintaining integrity in business activities and strictly implements relevant policies such as anti-bribery, anti-extortion, anti-fraud and anti-money laundering. We adopt a “zero-tolerance” attitude towards relevant violations, which is consistent with the values we have always upheld. We have formulated and implemented a series of internal rules and regulations in accordance with the Prevention of Bribery Ordinance of the Hong Kong Special Administrative Region, the Company Law of the People’s Republic of China, the Anti-Unfair Competition Law of the People’s Republic of China, the Interim Provisions on Prohibition of Commercial Bribery, and other national laws and regulations in the places where the Company operates, including the Management Policy for Anti-corruption, Anti-bribery, and Anti-money Laundering, the Interim Provisions on Business Entertainment and Gift-giving Management, the Souvenirs Management Rules and the Employee Conduct and Reward and Punishment Management Rules, so as to plug the loopholes of violations institutionally. In order to strengthen employees’ awareness of integrity, promote the steady and compliant development of the Company’s business and maintain a fair and transparent environment both internally and externally, we continue to improve Party conduct and integrity and combat corruption and require third-party business partners to sign the Letter of Commitment to Integrity so as to promote the integrity and sustainable development of our business value chain with the Group’s influence and we adhere to treating all our clients and business partners with integrity.

The Group has always regarded integrity as a fundamental principle of business operations. We fully implemented management requirements for anti-bribery, anti-extortion, anti-fraud, and anti-money laundering in all commercial activities, and maintained a “zero-tolerance” stance on any disciplinary or legal violations, reflecting our long-held value of integrity.

To ensure legal and compliant operations, we strictly complied with the Prevention of Bribery Ordinance of the Hong Kong Special Administrative Region, as well as relevant laws and regulations such as the Company Law of the People’s Republic of China, the Anti-Unfair Competition Law of the People’s Republic of China, and the Interim Provisions on the Prohibition of Commercial Bribery. We also formulated and implemented internal systems based on our business characteristics, including the Anti-Corruption, Anti-Bribery, and Anti-Money Laundering Management System, the Interim Provisions on Business Hospitality and Gift-Giving Management, the Souvenirs Management Rules, and the Employee Conduct and Reward/Punishment Management Provisions, thereby effectively preventing integrity risks at the institutional and mechanistic level.

Wilson Engineering Services Co. Ltd.

Meanwhile, we continued to advance the building of an integrity culture, creating an open and transparent business environment by strengthening employee education, improving the supervision system, and promoting Party conduct and clean government initiatives. We also required third-party business partners to sign the Letter of Commitment to Integrity, extending the principle of integrity to the entire value chain, jointly building an honest, stable, and sustainable business ecosystem, and serving every client and partner with integrity and professionalism.

Acts Prohibited by the Code of Business Conduct

To effectively mitigate the risk of corruption and foster a corporate culture of integrity, all employees, including directors, are required to complete a mandatory online training programme, covering topics such as our Group's Compliance Manual, basic knowledge of anti-corruption laws, the harms of fraud, and reporting channels. In addition, we have also compiled compliance and integrity training materials such as the Policy for Managing Recusal due to Conflict of Interest and the Compliance Management Policy to help directors and employees access and understand the Company's relevant rules and regulations at any time, safeguard the red line of integrity and compliance, and maintain vigilance in their daily work.

The Company has established a confidential whistleblowing channel (applicable to all internal and external stakeholders) to receive complaints against fraud, unethical conducts or actual/potential violations of laws and regulations and/or its policies. It ensures that whistleblowers do not have to fear persecution, discrimination or disadvantage as a result. During the Reporting Period, the Company received a total of 12 whistleblower cases, of which 4 did not meet the definition of "whistleblowing". We have completed investigations into 7 cases, of which 1 was substantiated and 6 could not be substantiated. As of 31 December 2025, one case was still under investigation. For the substantiated whistleblower cases, the management has taken appropriate follow-up actions.

To prevent future cases, it is crucial to implement robust remedial and preventive measures, including establishing an effective reporting mechanism, conducting thorough internal investigations, implementing a more robust compliance framework, providing protection for whistleblowers, and ensuring that appropriate disciplinary actions are taken for misconducts. These measures help enhance transparency, accountability, and trust within the Company, and reduce the likelihood of similar incidents in the future.

Through years of practical experience, we have gradually developed a sustainability strategy supported by five core pillars, which are “Innovation-Driven Green Future,” “Enhancing the QHSE System,” “Deepening Synergy and Win-Win Cooperation,” “Nurturing Employee Development,” and “Building a Better Society,” guiding the Group to continuously achieve breakthroughs in the field of sustainable development:

Board's Statement

The Group has a profound understanding that sustainable development is the critical foundation for the Company's sustained and stable operation. To this end, we continuously strengthen our governance structure and management processes, establishing an integrated governance system led and overseen by the Board of Directors, which incorporates ESG governance, risk management, and internal control. This system is comprehensively responsible for advancing the Group's sustainable development, including important tasks such as overseeing the identification and assessment of ESG and climate-related risks and opportunities, and ensuring the Group's ESG disclosures comply with the relevant requirements of the Environmental, Social and Governance Reporting Code in the Listing Rules. The Board of Directors has a Social Responsibility Executive Committee, which is responsible for following up on the implementation of ESG management, reporting the latest progress to the Board of Directors on a regular basis, and undertaking the responsibility of identifying and defining material ESG issues and significant risks for submission to the Board of Directors for deliberation.

The Group actively responds to the national "Dual Carbon" goals, has formulated guiding objectives in the environmental field in conjunction with our business layout and development stage, and continuously monitors the effectiveness of their implementation. Under the leadership of the Board, we integrate the concept of sustainability into our management policies, strategic planning, business models, and daily operations, formulating various emission reduction measures tailored to local conditions to proactively address the challenges posed by climate change. By continuously enhancing the level of environmental management and climate governance, the Group actively responds to the expectations of various stakeholders regarding our sustainable development performance, steadily advancing the implementation of our established sustainable development goals.

ESG Governance Structure

To better fulfil its corporate social responsibilities and integrate ESG principles and the concept of sustainable development into its daily operations, Wison Engineering has established a three-tier ESG management system spanning from the top to the grassroots, which is directly led by the Board of Directors, responsible for determining major issues and formulating strategies. The Social Responsibility Executive Committee serves as the governance core, responsible for identifying material ESG issues, coordinating targets, and liaising with various stakeholders, working in conjunction with the Board to promote the implementation of ESG-related work. ESG coordinators are designated within key departments such as the Finance Center, Human Resources Department, Project Management Department, Risk Control Department, Quality and Safety Department, Marketing Department, and Procurement Center. Acting as crucial support at the execution level, these coordinators collaborate closely to assist the Board and the Committee in completing various ESG tasks.

To address potential risks, such as those affecting the supply chain, fixed assets, and health and safety, posed by climate change, we have integrated sustainability factors into our existing risk management system. This enables us to promptly identify and assess ESG risks encountered during operations, prioritise these issues, and implement corresponding preventive and responsive measures. The Board of Directors is fully responsible for evaluating and determining material ESG risks, taking timely action to mitigate possible risks or minimise the losses caused by such risks to the greatest extent possible.

These documents clarify various work safety management requirements and implementation measures, ensuring that every work activity complies with safety standards, systematically reducing the risk of work safety incidents, and elevating the overall standard of work safety management.

Work Safety License

Guided by the management philosophy of "Safety First, Prevention is Key, Health Supreme, and Better Life," we established a comprehensive safety management system and health management procedures to safeguard the safety and health of all employees. The project safety management system comprises: the Provisions on the Project HSE Plan, the Provisions on HSE Training, the Safety Management Regulations for Various Construction Tasks, the Procedure for Emergency Response and Fire Safety, and others. The Project Health Management Procedures have established specific regulations covering common occupational health hazards (including exposure to toxic and hazardous chemicals) at worksites, occupational health management in office environments, and employee psychological health management.

To mitigate occupational health and safety hazards and promote comprehensive, standardised HSE management, in addition to developing the relevant documentation and guidelines, we have established a supporting monitoring system and inspection mechanism, thereby constructing a robust occupational health management system. By establishing employee health records and organising regular health check-ups, we systematically track and manage the health status of our employees, effectively reducing occupational health risks. In addition to general social security, we provide additional commercial insurance for employees who engage in jobs with high occupational disease risks to protect their personal safety during work.

To continuously improve our safety management level, we have introduced internationally advanced safety management methods, including Hazard and Operability Analysis (HAZOP), Safety Integrity Level (SIL) certification, and Job Hazard Analysis (JHA), to scientifically identify potential hazards and risks and take effective preventive and control measures. By creating a safe work environment, strengthening employee safety training, and advocating for compliance with safety operating procedures, we continuously enhance the safety awareness of all employees, significantly reducing the likelihood of accidents.

Furthermore, the Group has equipped itself with modern safety equipment and protective gear, providing employees with the necessary tools and safety guarantees, thereby effectively enhancing on-site risk identification and prevention capabilities. Over the past three years, we have not experienced any work-related fatalities. During the Reporting Period, the Group did not receive any complaints or litigation regarding violations of health and safety-related laws. Our investment in HSE reached RMB37.56 million. The lost time injury frequency rate (LTIFR) per 200,000 man-hours was zero, and the total recordable incident rate (TRIR) was 0.026, fully demonstrating our solid achievements and firm commitment in safety management.

Sudden Risk Prevention and Control

The Group has formulated a series of emergency plans with reference to relevant laws and regulations such as the Work Safety Law of the People's Republic of China and the Emergency Response Law, including Wilson Engineering Comprehensive Emergency Plan, Wilson Engineering Headquarters (Wison Centre) Emergency Plan, and Emergency Plans for Branches and Project Departments, forming a three-tier safety emergency mechanism covering the entire organisation.

The aforementioned series of plans defines the emergency organisational structure, division of responsibilities, and response procedures, ensuring that employees can take swift and orderly measures in emergency situations to minimise losses and ensure personnel safety. To maintain the applicability and effectiveness of the plans, we regularly organise assessments, training, and drills to continuously improve employees' emergency response capabilities.

The published Procedures for Identification and Evaluation of Hazard Sources and Environmental Factors sets out how hazard source identification and risk assessment are carried out across various stages of its operations, including project design, procurement, construction, as well as office and business travel management, along with the corresponding risk control measures. Upholding the work safety policy of "People-oriented, Safety First", we conduct regular on-site inspections, monitor hazards and environmental factors, and ensure construction safety is under control, thereby effectively identifying and eliminating potential risks during operations.

Prevention through Practice, Safety First — 2025 Annual Emergency Drill

To enhance fire safety management standards and employees' emergency response capabilities, the Group organised and conducted the 2025 Annual Fire Emergency Drill on 24 October 2025. The drill simulated a fire caused by a short circuit, covering stages such as alarm response, personnel evacuation, emergency rescue, and practical operation of fire-fighting equipment, comprehensively testing the coordination and effectiveness of the fire protection system. Prior to the drill, the Wison Centre completed system linkage tests and specialised training, clarifying responsibilities and evacuation procedures. Upon the alarm activation, all employees evacuated orderly along designated routes under guidance, safely assembling at the designated point within 10 minutes. Firefighters simultaneously conducted fire extinguishing and equipment demonstrations. The drill proceeded in an orderly and effective manner, further strengthening employees' safety awareness and the site's emergency response capabilities.

In 2025, the Group's domestic and overseas project departments organised a total of over 20 emergency drills covering various scenarios, including heatstroke prevention, falling object protection, camp fire safety, and attack prevention. These drills tested the effectiveness of the emergency response plans, enhanced the emergency response capabilities of the project departments, and raised the emergency awareness of all personnel.

Safety Culture Training

Wison Engineering places great emphasis on cultivating and disseminating a safety culture. Through multi-level safety awareness and training activities, we ensure that key safety information is effectively communicated to every employee. New employees receive safety training upon onboarding, ensuring they are familiar with relevant safety procedures from the outset. We also provide specialised training at each project site on crane safety planning, emergency management, and hazardous materials management, helping employees acquire essential safety knowledge and practical skills. We continuously evaluate the effectiveness of our training and optimise its content, helping employees continuously improve their occupational health and safety and management capabilities.

3.3 PROJECT QUALITY SUPERVISION

High-Quality Project Delivery

In terms of project quality supervision, Wilson Engineering strictly adheres to the ISO9001 Quality Management System standard to ensure the high-quality delivery of all projects. We have developed and implemented detailed quality management procedures, covering 27 key management documents, spanning the entire process from project initiation to final acceptance. These documents not only standardise the construction process but also clarify the specific requirements for quality inspection and control. By rigorously implementing these procedures and continuously optimising each business link, we can systematically monitor project quality, promptly identify and correct potential problems, thereby effectively preventing quality incidents and achieving a dual improvement in work efficiency and overall project quality. Through in-depth analysis and the development of effective quality improvement measures, we successfully implemented model projects management and special processes management, continuously optimised our quality management system, and achieved a systematic improvement in our quality management standards.

Furthermore, we regularly conduct internal audits and management reviews to promote the continuous improvement and optimisation of our quality management system, constantly enhancing project supervision and providing our clients with higher quality and more reliable project deliverables. During the Year, Wilson Engineering's various departments collaborated and leveraged their professional capabilities to successfully complete several major engineering projects. These projects not only fully met the high-standard requirements of our clients but also earned their high recognition for delivery quality. The Group has always upheld its own advantages, striving to meet and exceed client expectations. With a solid track record and a good market reputation, it has laid a firm foundation for its sustainable development.

Quality Awareness Enhancement

During the 2025 Quality Month, the Group launched a series of quality activities under the theme "Driving Quality-led Transformation, Shaping a Green Energy Future". These activities included: organising cross-departmental quality seminars to enhance employees' professional competence and process quality control capabilities; displaying "Quality Month" themed posters at the headquarters lobby to promote quality awareness across the organisation; selecting typical quality cases from the design, procurement and construction phases, and collecting process optimisation proposals and quality improvement initiatives; and hosting a "Quality Day" themed funfair to integrate quality knowledge promotion into engaging activities, thereby further enhancing quality awareness among all employees. Various project departments actively responded to the "Quality Month" initiatives, embedding quality control concepts deeply into frontline construction processes. In particular, the Saudi DPCU project achieved dual improvements in both welding quality and operational efficiency through measures such as full-process QC intervention in welding operations, strict lifecycle control of welding electrodes, and optimisation of the welding environment. Guangxi Huayi's MTO project strictly implemented a joint inspection and sign-off system for quality inspection and acceptance, and established a welder incentive

and dynamic exit mechanism, effectively strengthening the quality responsibility awareness of all personnel. Through mechanisms such as welder skills competitions and first-sample benchmarking, the department of Guangxi Huayi's MTO project enhanced the quality awareness and technical capabilities of construction workers. It also organised the "Every Weld is a Commitment" campaign, in which over 200 welders involved in the project made a pledge through a "six-month quality improvement" ceremonial signing, providing strong assurance for fundamentally ensuring construction quality.

All projects implemented quality measures at various levels, effectively preventing the recurrence of quality issues and significantly reducing common quality deficiencies across different processes, thereby providing solid support for efficient project execution and high-quality delivery.

Areas to be covered by subsequent processes (such as steel reinforcement fixing, waterproofing layers) must be signed off by a site engineer for confirmation before the next construction step can proceed.
For key materials such as steel reinforcement, cement, and concrete delivered to the site, on-site sampling must be conducted under the witness of Quality Control (QC) personnel and sent to a third-party testing institution, with usage strictly prohibited prior to inspection.
During critical processes such as concrete pouring and backfill compaction for foundations, the construction engineers and QC personnel must be present for full-process supervision.

Syngas Retrofitting Project of Yangmei Group Zibo Qilu First Fertilizer

Through the effective operation and continuous improvement of the quality management system, full-process and comprehensive control was implemented over the management of engineering project design, procurement, and construction quality.
The project department issued quality management documents, requiring the construction contractor to organise training and conduct proper technical, safety, and quality pre-construction briefings.
Welder entry training and examinations were organised. Upon passing, welders were issued identification badges, thereby improving welding quality and the qualification rate.
During the construction process, inspection and testing, as well as inspection requests, were strictly carried out according to the approved ITP control points. After passing the self-inspection by the construction contractor, specialist inspection by the general contractor's engineer, and mutual inspection between preceding and subsequent work steps, a joint inspection was requested from the supervisor and the client upon passing the internal checks. A joint inspection form was signed upon completion, ensuring process quality to remain under control.

3.4 ENVIRONMENTAL PROTECTION AND LOW-CARBON OPERATION

Implementation of Environmental Protection Measures

We strictly comply with the Environmental Protection Law of the People's Republic of China, the Regulations on Environmental Protection Management of Construction Projects, and other relevant laws and regulations. We also implemented internal systems such as the Environmental Management Procedures, the Hazardous Materials Management Regulations, the Site Civilised Construction Management Regulations, and Waste Management Regulations. We clearly define management requirements for emissions, waste, and energy and water resources, and have been promoting various measures, including energy conservation and consumption reduction, strengthening the application of renewable energy, and systematically reducing greenhouse gas emissions. These measures effectively minimise negative environmental impacts and contributed to building an environmentally friendly society.

To ensure the effective implementation of environmental management, Wison Engineering has established a professional environmental management team responsible for environmental supervision of all project departments. Dedicated environmental management personnel were assigned to both the project site and construction subcontractors to ensure the implementation of environmental management guidelines, environmental protection facilities, and pollution prevention measures, thereby improving resource utilisation efficiency and reducing environmental pollution risks. Furthermore, we have established a dedicated Energy Conservation and Emission Reduction Team to oversee energy consumption management in the office area. Through measures such as holding energy conservation and emission reduction mobilisation meetings and optimising daily operational processes, we systematically promoted the construction of a low-carbon working environment. During the Reporting Period, the Group did not receive any reports of violations of environmental protection laws and regulations.

The Group has established environmental targets for emissions, waste, energy use efficiency, and water use efficiency, and confirmed that these targets remain applicable for the Year. We actively implemented the Group's systems in areas such as greenhouse gas emission reduction, energy conservation, water conservation, and waste reduction, comprehensively rolling out various measures. In the future, while maintaining a similar operational scale, we will maintain or gradually reduce the intensity of our greenhouse gas emissions (Scope 1 and Scope 2), waste generation, and electricity and water consumption. We have reviewed the progress of our targets. During the Year, progress across all targets remained satisfactory. Greenhouse gas emission intensity (Scope 1 and Scope 2), waste generation intensity, electricity consumption intensity and water consumption intensity all decreased compared with last year. These results demonstrate our efforts in environmental management and low-carbon operations.

Addressing Climate Change

Against the backdrop of the Chinese government's active promotion of phasing out outdated production capacity and accelerating the development of new energy sources such as hydrogen, wind, and photovoltaic power, the engineering services market is witnessing new development opportunities. We actively responded to China's strategic goals of "Carbon Peak and Carbon Neutrality", continuously deepened the concept of green and low-carbon development, and focused on technological R&D and innovation in key areas such as the entire hydrogen industry chain, industrial off-gas capture, and $\mathrm{CO}_{2}$ chemical carbon fixation, thereby promoting the application of clean energy and low-carbon transition, with the concepts of sustainable development and environmental protection fully integrated into the entire project implementation process.

We proactively addressed global warming, systematically identifying and analysing the physical risks, transition risks, related development opportunities, and potential financial impacts brought by climate change. We have formulated response measures, comprehensively incorporated climate adaptation factors into business decisions and strategic priorities, continuously enhancing climate resilience in our operations, and contributing to overall societal carbon emission reduction.

Governance

The Group has established a three-tier social responsibility governance structure comprising the "Board of Directors (decision-making level) — Social Responsibility Executive Committee (coordination level) — Departmental ESG Coordinators (execution level)", systematically integrating climate-related topics into the entire process of corporate decision-making, management, and oversight. The Board of Directors assumes overall leadership and supervisory responsibility for ESG governance. It reviews and approves the Group's ESG and climate strategies, and regularly receives reports from management on the identification of climate risks and opportunities, the implementation of response measures, and overall progress. During the Year, both the Board of Directors and management participated in two hours of climate-related training, achieving $100\%$ coverage.

The Social Responsibility Executive Committee is responsible for coordinating and driving the concrete implementation of various ESG and climate-related tasks, ensuring the effective execution of strategies. The execution level undertakes the supporting roles of cross-departmental communication and the implementation of ESG information and policy management, to ensure the smooth implementation of climate actions across all business segments.

Strategy

To address the challenges posed by climate change, the Group continuously monitors the dynamic changes in the climate environment and policy direction, and has systematically compiled a list of climate-related physical and transition risks relevant to its business operations. We categorise and assess these risks based on their severity levels, and formulate and implement corresponding response measures in line with our business characteristics, to minimise the potential impacts of climate change to the greatest extent possible.

We carried out preliminary scenario analysis. As the Group is principally engaged in the consultation, engineering, procurement, construction, and project management of large-scale projects related to petrochemical, oil and gas processing, and new energy, with business scenarios involving the construction of large plants, modular delivery, logistics for equipment and material procurement, as well as project sites in some coastal, offshore, or high-temperature regions, it mainly used scenario analysis to examine the potential financial impacts of factors, such as extreme weather, supply chain and logistics disruptions, policies, technologies, and market transitions, on project delivery, health, safety and environment management, cost investment, and payment collection arrangements. We made reference to HKEX's Guidance on Climate Disclosures, and the overview of scenarios published by the United Nations Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA), as well as the relevant content of China's Fourth National Communication on Climate Change. With regard to climate-related physical risks, the Group assessed physical risks under different warming scenarios with reference to the low-emissions (RCP 2.6 and SSP1-2.6) and high-emissions warming pathways (RCP8.5 and SSP5-8.5). In the light of transition risks, the Group assessed the potential impacts of policy, technology, market, and reputation on its business development prospects with reference to the Stated Policies Scenario (STEPS) and the Net Zero Emissions (NZE) scenario.

• Domestic and international oil and gas processing, petrochemical and coal chemical markets; new energy project opportunity markets in Europe, the United States, Canada and Southeast Asia

Growing concern of stakeholders on sustainability, with client investment and project demand shifting towards low-carbon, high-efficiency, and green products and services | • Under the STEPS scenario, customer and market demand for low-carbon services will gradually increase, and traditional and green businesses may develop in parallel for a period, with a relatively gradual adjustment in the revenue structure
• Under the NZE scenario, the pace of low-carbon transition will accelerate, and traditional high-carbon projects may face pressure in some market segments, but the demand for new energy and carbon reduction projects that the Group has already developed is expected to increase, and the proportion of green revenue is expected to rise. Additionally, investments in market development and capacity building may also increase in the short-to-medium term | • Respond to national policies and international trends by focusing on new energy business and energy saving & emission reduction measures
• Get informed of the latest policy requirements by communicating with clients, industry associations, and government organs and enhance staff training on these requirements
• Proactively implement energy conservation and consumption reduction and cleaner production to decrease carbon emissions
• Take climate-related factors into account in business operation and consider the feasibility for using new and alternative energy sources |

Major relevant premises/business scenarios:
• Shanghai R&D and design platform, domestic carbon reduction demonstration projects, and new energy and low-carbon project development in Europe, the United States, Canada and Southeast Asia

Increase relevant R&D costs and investments in technology innovation for the transition to a low-carbon economy | • Under the STEPS scenario, the requirements for upgrades of low-carbon technology and customer technology will gradually increase, and the Group may need to continuously increase investment in technology R&D, but the overall pace of investment will be relatively stable
• Under the NZE scenario, the iteration and application process of low-carbon technology will accelerate. If the Group is weak in technology reserves, R&D conversion, or engineering application capabilities, it may affect market competitiveness. Meanwhile, the Group may also increase its R&D and capital investment in fields, such as hydrogen energy, carbon capture, and low-carbon processes, but medium- to long-term technological advantages are expected to be established and business growth is achieved | • Develop new and clean energy sectors such as solar power, wind power, hydrogen energy, and CO_{2} integrated use
• Follow the development and application of new technologies in the industry, e.g. developing carbon capture and equipment to reduce carbon emissions during production
• Study on the feasibility and benefits for applying the latest low-carbon and energy-saving technologies to operations |
| | Policy and legal risk | Low to moderate | Applicable scenarios:
• Policy continuation pathway STEPS (projected warming to over 2°C)

Major relevant premises/business scenarios:
• Regulatory environments in Chinese mainland and Hong Kong; Oil, gas, and industrial emission reduction policies in the countries where Middle East projects are located; Compliance and carbon border-related requirements in the regions where overseas projects are located

China is resolutely implementing the "dual carbon" policy, promoting advanced technology and factory transformation and upgrading, and encouraging the use of new energy sources and the development of new materials | • Under the STEPS scenario, as current and announced policies have been gradually implemented, the Group will face continuously increasing investments in compliance, disclosure, supply chain management, and technology upgrades, but the overall impact will be relatively gradual
• Under the NZE scenario, carbon constraints, green standards, and climate disclosure requirements may be satisfied faster and become more stringent, potentially further increasing the Group's short- to medium-term compliance costs, R&D spending, and capital investment. However, if the Group continuously advances its low-carbon technology and operates green business, it is expected to benefit from policy support and increased opportunities for related projects | • Keep abreast of the latest climate change related laws and regulations and integrate them into business management strategies
• Accelerate the pace of penetration into new energy business, and give full play to the advantages in independent R&D and engineering technologies
• Incorporate the "3060 Dual Carbon Goal" into the staff training program
• Increase investment in the development of technologies and projects in low-carbon and emission reduction |

Major relevant premises/business scenarios:
• Hong Kong capital market, domestic and foreign clients and partners, overseas project owners (such as large oil and gas clients in the Middle East), and international supply chain partners

As higher standards on climate actions are requested by the stakeholders, failure to respond effectively could jeopardize the reputation of the business | • Under the STEPS scenario, investors, clients, and other stakeholders will continuously pay more attention on climate governance, information disclosure, and emission reduction commitments. Inadequate disclosure or response may affect the corporate image and financing communication
• Under the NZE scenario, the capital market and clients will put forward more stringent requirements for corporate climate performance, emission reduction targets, and transition paths. If the Group fails to effectively demonstrate its climate governance capabilities, emission reduction progress, and low-carbon strategy, it may have a more significant impact on its brand image, financing availability, and business cooperation. Conversely, continuous improvement in disclosure and action will help enhance market recognition and long-term value | • Proactively respond to the national call for “dual carbon” by actively communicating with stakeholders, formulating and disclosing emission reduction targets
• Pay more attention on climate change, including strengthening the identification, management and planning of climate change risks
• Publicly disclose the Company’s GHG emissions data and its efforts on low-carbon operations, etc. in ESG reports, to effectively maintain its corporate image
• Establish all-round communication channels with stakeholders, to regularly communicate with stakeholders and provide timely feedback on the measures and actions taken by the Company on climate issues |

The Group identified potential financial impacts of climate-related risks at the operational level, mainly including operational disruptions, maintenance and resilience investment costs, and compliance expenses. Due to the current lack of unified financial mapping and quantitative methods, the specific range of financial impacts was not disclosed in this Report. In the future, the Group will focus on establishing a quantitative ledger and internal control processes for climate-related financial impacts (such as the duration of work stoppages caused by extreme weather, emergency expenditures, and changes in energy consumption), and will gradually achieve quantitative disclosure once the data is complete to enhance the comparability and practicality of information.

Currently, the climate-related risks identified by the Group are considered potential anticipated impacts and have not yet resulted in any material adverse effect on asset values. and information related to the identified climate-related opportunities is not suitable for public disclosure.

Looking ahead, we will continue to fulfil the Company's responsibilities in climate governance. Leveraging our existing professional capabilities, comprehensive strengths, and resource allocation, we will continuously deepen and refine our climate scenario analysis work. Simultaneously, we will closely monitor climate risks and potential opportunities relevant to our business operations. We will reassess climate-related risks and opportunities systematically, when necessary, continuously optimise our response strategies, and enhance our environmental management standards and the overall resilience of the enterprise in the context of climate change.

Risk Management

To effectively address the potential impacts of climate change on business operations, the Group has established a systematic climate risk management mechanism. Building upon our existing risk management framework, we have comprehensively incorporated climate-related considerations. By integrating historical disaster data from operational locations, regional physical risk characteristics, and policy and market trends, we systematically identify various climate risks and continuously refine management processes to effectively mitigate the negative impacts of climate change.

We systematically identify and assess climate-related risks through the following steps:

Risk Identification: Based on historical data, scientific research, and industry analysis, we identify climate change factors that may affect the Company's operations, including physical risks such as extreme weather, and transition risks such as changes in policies and regulations.
Risk Assessment: We conduct qualitative assessments of the identified risks, comprehensively analysing their potential business impact and probability of occurrence.
Risk Prioritisation: Based on the nature and potential impact of the risks, we classify them into three levels: high, moderate, and low, providing a basis for developing differentiated response strategies.

The Group fully integrates the climate risk management process into the overall enterprise risk management framework, promoting cross-departmental collaboration in addressing climate challenges. We have implemented several concrete measures, including the development of emergency response plans for extreme weather, conducting climate adaptation and emergency response training for employees, and enhancing overall risk awareness and response capabilities across the workforce. Simultaneously, in line with TCFD recommendations, we regularly disclose climate-related risk information, covering the entire process of risk identification, assessment, and control, thereby continuously enhancing management transparency and stakeholder trust.

Looking ahead, we will further integrate climate risk assessment into the overall risk management framework. Through regular reviews, continuous adjustments, and mechanism optimisation, we will consistently strengthen climate-related response measures, enhancing the Group's management effectiveness and operational resilience in the context of climate change.

Metrics and Targets

The Group regularly collects statistics on and publicly discloses its total greenhouse gas emissions and emission intensity. Through continuous monitoring of key metrics and the implementation of systematic emission reduction measures, we ensure the achievement of established reduction targets while maintaining business growth. During the Year, SGS, an internationally recognised testing, inspection, and certification organisation, formally issued an ISO 14064-1:2018 greenhouse gas verification statement to Wison Engineering. The verification confirmed that Wison Engineering's identification of greenhouse gas emission sources is comprehensive and complete. Its greenhouse gas inventory meets international standard requirements across multiple dimensions, including completeness, consistency, accuracy, and transparency. As a benchmark enterprise in the energy engineering sector, Wison Engineering passed the greenhouse gas verification to a high standard, obtaining the first ISO 14064-1:2018 certificate in China's petrochemical engineering construction field to fully disclose Scope 3 emissions. Based on the 2024 carbon inventory data, Wison Engineering has comprehensively established its carbon emission baseline, laying the groundwork for systematically planning its decarbonisation pathway. Subsequently, Wison Engineering will establish a tiered decarbonisation pathway combining short-term and long-term goals, continuously driving green development.

Our Scope 3 greenhouse gas emission calculations cover: Category 1 Purchased Goods and Services; Category 2 Capital Goods; Category 3 Fuel- and Energy-Related Activities; Category 4 Upstream Transportation and Distribution; Category 5 Waste Generated in Operations; Category 6 Business Travel; Category 7 Employee Commuting; Category 8 Upstream Leased Assets; and Category 13 Downstream Leased Assets. By enhancing the accounting for Scope 3 emissions, we have gained a clearer identification of the main sources of our carbon emissions, providing data support for formulating precise and effective emission reduction strategies.

During the Year, our greenhouse gas emission intensity (Scope 1 and Scope 2) and total greenhouse gas emission intensity (Scopes 1, 2 and 3) both decreased compared to the last year, as detailed below:

Climate-related Targets

We strictly follow emission reduction systems and measures. In the future, assuming a similar level of operations, we will maintain or gradually reduce the intensity of GHG emissions (Scope 1 and Scope 2). The Group has implemented various low-carbon operational measures to reduce greenhouse gas emissions. For more information on the initiatives we have taken to achieve our environmental targets, please refer to Section 5.1, "Continued Advancement of Green and Low-Carbon Operations".

The Group conducts its climate-related disclosures in accordance with the requirements of Appendix C2, Part D of the ESG Reporting Code, adhering to the "comply or explain" principle. As some projects are currently in the capacity-building phase, with the underlying data infrastructure still under development, and in accordance with the "reasonable information relief" principle, we have prioritised establishing the governance framework and data foundation for the Year, disclosing qualitative descriptions. We have defined a clear roadmap for improvement and will continuously refine our data foundation and measurement methodologies. Our overall disclosure standards will progressively improve year-on-year as data coverage and methodological maturity increase, ensuring that the information is traceable, comparable, and subject to continuous enhancement.

Air Pollutant Management

The Group's Provisions on Solid Waste, Waste Gas (Air), and Wastewater Management specify our management of air pollutant emissions during operations. The Group implements a zoning control principle for waste gas management, covering construction sites as well as office and living areas, ensuring full-process compliance with environmental regulations and the implementation of green construction principles.

I. Waste Gas Management at Construction Sites

Project departments and construction contractors share joint responsibility for on-site waste gas control. Non-hazardous waste gases must be discharged in compliance with applicable standards, and noise emissions must be strictly controlled to ensure compliance with relevant standards. For hazardous waste gases, the construction contractor is responsible for their compliant disposal and discharge. If the contractor lacks the requisite treatment capacity, it must engage a licensed facility for professional treatment. The HSE management team of the project department oversees the entire process to ensure standardised operations and controlled emissions.

II. Waste Gas Management in Office and Living Areas

Waste gases generated in these areas are discharged either via a dedicated piping system into the client's designated drainage network, or after undergoing harmless treatment to ensure compliant emissions. Routine management is executed by the administrative group, with the HSE management team performing supervisory and inspection duties to ensure all discharges are lawful and compliant.

We continuously promote the implementation of green construction methods, actively adopt various green processes and technical solutions to reduce air pollutant emissions at source, and are committed to achieving safe, standardised, and green waste gas management.

During the Reporting Period, the Group's air pollutant emissions related to vehicle exhaust⁴ are as follows:

Emissions	Unit	2024 Emissions	2025 Emissions⁵
Nitrogen oxides (NOₓ)	kg	9,652.51	15,252.40
Sulphur oxides (SOₓ)	kg	7.03	14.42
Particles	kg	955.10	1,426.52

Simultaneously, the Group continuously increases investment in R&D and design, striving to reduce and manage air pollutant emissions. We actively develop and introduce green, environmentally friendly, and efficient new processes and technologies, aiming to alleviate environmental pressure at source and promote green transition and sustainable development.

⁴ We calculated the Group’s vehicle air pollutant emissions with reference to the Stock Exchange’s How to Prepare on Environmental, Social and Governance Report — Appendix 2: Reporting Guidance on Environmental KPIs.

⁵ Air pollutants related to vehicle emissions increased year on year, largely due to the fact that overseas projects entered the peak construction period, leading to a significant increase in vehicle usage.

Emissions and Waste Management

The Group strictly adheres to the pollutant emission laws and regulations of the countries and regions in which it operates, actively promoting pollution reduction and comprehensive management measures. Through the formulation of internal systems such as the Provisions on Waste Management, the Hazardous Materials Management Regulations, the Energy and Resource Consumption Management Regulations and the Procedure for Environmental Management, we have systematically standardised environmental protection efforts in our business activities. This includes the classification, treatment, and disposal processes for solid waste, waste gases, and wastewater generated in engineering projects, and is aimed at continuously reducing pollutant emissions from our operations and comprehensively managing our environmental footprint.

Our Procedure for Environmental Management clearly defines the environmental management responsibilities of relevant departments, including the Quality and Safety Department, the President's Office, and project departments, forming a collaborative and integrated accountability system. Through systematic identification and assessment of environmental factors, we ensure that all pollutant emissions consistently comply with national standards. In accordance with the Provisions on Waste Management, we implement classification management based on the nature, source, and form of the waste. By optimising raw material usage and inventory control, we strive to reduce waste generation at source, actively promote resource recycling, continuously improve waste management standards, thereby achieving waste reduction and the ongoing enhancement of environmental performance.

The waste we generate is categorised into two primary types based on its nature: hazardous waste and non-hazardous waste. It is further sub-divided into categories such as chemical waste, biological waste, industrial waste, and general waste. For each waste category, we have established strict procedures for collection, storage, and transportation, including the use of compliant containers with clear labelling. All waste must be transferred to licensed facilities possessing the appropriate qualifications for proper disposal. Department heads are responsible for ensuring that employees fully understand and master the waste handling processes and standards, and for reinforcing execution capabilities through regular training. If external contractors perform waste handling operations on the Company's premises, they must strictly adhere to the Group's relevant regulations, while designated Company personnel supervise the operations on-site to ensure compliance with environmental requirements and the effective control of environmental risks.

Our waste management consistently adheres to the following five key principles. We meticulously follow specific handling measures and standards to achieve fully traceable management throughout the entire lifecycle from generation, storage, and transfer to final disposal:

Classification Management	Source Reduction	Reuse	Recycling	Off-site Disposal
Overall classification, collection, and management of waste in accordance with the laws, regulations, and standards of the project location	Adopting effective measures to reduce waste generation at source, such as raw material control, inventory control and management, and material substitution	Reintroducing materials or products into the production process in their original form for reuse	Recovering waste as a resource or by-product to reduce overall waste generation	Transporting waste to designated off-site locations for disposal or engaging qualified waste disposal contractors/service providers for treatment
Specific Measures and Regulations for Waste Disposal
---	---	---	---	---
All waste-generating facilities must place containers such as waste bins in areas such as the worksite, offices, and living quarters for the temporary storage of waste. The colour and markings of the bins must comply with regulatory and standard requirements;	If a client has specific regulations for waste disposal within the project construction scope approved by the administrative department, these must be followed; Otherwise, the specific method and location for disposal must be agreed upon with the client through consultation. Unauthorised disposal, discharge, or on-site landfilling is strictly prohibited;	A waste disposal ledger must be established. Accurate records must be kept for all waste, including the quantity generated, classification, treatment method, final disposal site, and the waste disposal contractor; These records must be uniformly filed and retained. For hazardous waste, a detailed disposal ledger must be maintained to achieve fully traceable management throughout the entire lifecycle from generation, storage, and transfer to final disposal;	Regular inspections and audits of all waste management stages must be conducted to ensure full compliance with internal regulations and external regulatory requirements;	Any incidents of non-compliant handling must be reported immediately, and effective corrective measures must be taken promptly to continuously enhance the standardisation and safety of waste management.

7 The waste emission intensity decreased during the Year compared with last year, demonstrating the effectiveness of our waste management efforts.

Energy Management

To systematically advance the standardisation and efficiency of energy management, the Group strictly implements the Provisions on Energy and Resource Consumption Management. By clarifying the management scope and the responsibilities of each department, a clear energy usage accountability system has been established, enabling effective control over energy consumption.

We continuously optimise resource allocation, integrating energy-saving concepts into the design phase and prioritising the procurement of energy-efficient equipment, thereby reducing unnecessary energy consumption at the source. Specifically, the design centre must incorporate energy-saving measures in engineering design, while the procurement department is responsible for ensuring purchased equipment meets energy efficiency standards. The Quality and Safety Department assists in reviewing suppliers' low-carbon reports, screening carbon footprint reports that meet the carbon verification requirements, and deepening carbon reduction efforts across the supply chain.

Furthermore, by establishing a green procurement channel, project departments and construction contractors are empowered to continuously monitor and dynamically optimise energy use during project implementation, thereby ensuring the effective execution of energy management policies.

The Group implements a zoning control principle for energy management, covering construction sites and office/living areas:

Green Construction

Throughout the entire lifecycle of project construction, we consistently adhere to the core principles of "People-oriented, Adapting to Local Conditions, Prioritising Environmental Protection, and Efficient Resource Utilisation". We strictly comply with relevant national laws and regulations, always placing environmental protection and resource conservation at the forefront. Guided by our internally implemented the Provisions for Civilised On-site Construction Management, we ensure that all project sites fully meet green and civilised construction standards, achieving our green construction objectives.

We attach great importance to the impact of project construction on soil, water bodies, and air quality. By implementing targeted protection and management measures, we strive to achieve harmony between engineering construction and the surrounding natural environment. We prioritise the adoption of environmentally friendly new technologies, equipment, materials, and processes to reduce waste generation, optimise resource utilisation, lower energy consumption, and enhance construction efficiency. By continuously promoting the innovation and application of green construction technologies, we effectively mitigate the negative environmental impact of project construction and reduce pressure on energy and resource consumption. These systematic practices not only demonstrate our firm commitment to environmental protection but also provide valuable examples for the sustainable development of the industry.

Prior to construction, we systematically conduct environmental impact assessments and develop specialised green construction plans, exploring hybrid power supply solutions for project camps that combine photovoltaic and diesel power generation, thereby optimising the energy mix and material selection from the outset. During the construction process, we rigorously implement energy-saving, consumption-reduction, and pollution prevention and control measures, adopting meticulous management and technological innovations such as the addition of online data entry for greenhouse gas inventory reporting in the Company's engineering BI application, to minimise environmental impact to the greatest extent possible. During the Year, we implemented representative green construction practices in several key projects, which have formed replicable and promotable model cases. These cases not only reflect our ongoing investment in environmental protection and energy conservation but also provide valuable references for the industry's green transition.

Prior to Construction

Relevant departments conduct an initial site environmental survey to understand the existing environmental conditions;
The environmental management team then formulates project risk response measures based on the relevant assessment findings, including the development of a construction plan that outlines green construction management and technical requirements, clearly specifying resource conservation measures;
The environmental management team is responsible for developing specialised green construction plans. For example, it formulates a dedicated energy conservation and utilisation plan to ensure energy consumption is minimised during construction;
It also develops a dedicated solid waste (including construction debris) management plan to ensure proper waste handling and reduce negative environmental impacts.

During Construction

We assist construction contractors in adopting construction techniques and technologies that conserve resources and protect the environment, while simultaneously restricting the use of or phasing out outdated construction methods and processes that are energy-intensive or detrimental to environmental protection;
When formulating construction plans and specialised green construction schemes, we coordinate operations to establish effective control measures covering soil protection, waste management, dust and fume control, and noise mitigation; Dust suppression is rigorously implemented through the installation of vehicle wheel washers and mist cannons on site, along with the use of dust-proof nets to cover exposed soil;
We ensure compliance with environmental management standards on construction sites and implement energy and material conservation management. This includes optimising energy usage, reducing unnecessary wastage of resources, and adopting corresponding energy-saving measures.

Regular conduct of organisational surveys and qualification audits of suppliers, alongside ongoing site visits to key material suppliers, to monitor and assess supplier performance in areas such as production processes, corporate operations, and system capabilities

Systematic organisation of the existing supplier list, with classification and grading based on dimensions such as quality, delivery, brand, and commercial reputation. Inactive suppliers are phased out, while new suppliers are incorporated

Within the overall framework of strengthening quality control and integrity compliance, we have established a categorised supplier performance management mechanism. We employ mid-year and annual evaluations to identify significant quality and schedule deviations during contract execution, as well as suppliers that violate integrity and compliance requirements. Suppliers confirmed as problematic through departmental approval are placed on a disqualified list and subjected to qualification restrictions, strictly prohibiting their participation in subsequent bidding and cooperation. To ensure that product and service quality meets requirements, we conduct site visits to suppliers as necessary. During contract execution, we perform progress monitoring and quality inspection at supplier factories, tracking key milestones and quality control points to ensure the quality of supplied products. To enhance supplier monitoring capabilities, we conduct regular assessments of cooperative suppliers in accordance with the Provisions on Engineering Material Supplier Management, and develop supplier on-site visit plans. We maintain timely communication with key suppliers, ensuring high standards for procurement compliance, quality stability, and delivery reliability. During the Reporting Period, to strengthen proactive quality management of suppliers, the Group selected 15 key suppliers to undergo second-party quality management system audits. Access opinions were provided based on the actual findings of these quality system audits.

Environmental and Social Requirements for Suppliers

Wilson Engineering places great importance on corporate social responsibility codes of conduct, with a key focus on labour standards, health and safety, and environmental protection. We are committed to establishing long-term, stable, and mutually trusting cooperative relationships with suppliers that prioritise social responsibility. To ensure comprehensive compliance, we strictly adhere to the relevant laws and regulations of the People's Republic of China, including the Anti-Unfair Competition Law, the Civil Code, and the Tendering and Bidding Law. Furthermore, we have developed internal management systems, such as the Anti-Corruption, Anti-Bribery, and Anti-Money Laundering Management System and the Contract Negotiation Management Measures, to strengthen the foundation of compliance and ethical operations.

When collaborating with suppliers, we require them to fully understand, sign, and comply with the Wilson Engineering Project HSE Management Requirements and the Equipment Packaging, Marking, and Transportation Requirements. To enhance the quality management level of our supply chain, we require suppliers to obtain ISO 9001 Quality Management System certification. All else being equal, we give preference to suppliers that have also obtained certifications such as ISO 14001 Environmental Management System, OHSAS 18001/ISO 45001 Occupational Health and Safety Management System, and ISO 27001 Information Security Management System.

During the Reporting Period, to strengthen the identification and management of environmental risks within the supply chain, we optimised our supplier qualification system, developed green procurement indicators for tendering, collected carbon footprint verification reports from key suppliers, and conducted a comprehensive assessment of suppliers' green performance. We have established a green supply chain management system. The Provisions on Engineering Material Supplier Management have been updated to incorporate content related to green and low-carbon indicators. Requirements for ISO 14064 greenhouse gas verification certification, ISO 14067 product carbon footprint certification, sustainable material certification, and HSE have been added to the supplier qualification and evaluation processes. We encourage suppliers to value and strengthen their green and low-carbon initiatives, environmental protection efforts, and occupational health management activities, continuously enhancing the overall quality and social responsibility level of the supply chain. Through these measures, we are committed to building a high-quality and responsible supply chain system, contributing value to the harmonious development of society and the environment.

Wison Engineering is firmly committed to upholding the integrity and transparency of business activities. We strictly require all suppliers to sign the Integrity Commitment Letter prior to cooperation, ensuring that both parties comply with laws and regulations in commercial dealings and eliminate any form of non-compliant operations or improper benefit exchange. We believe this measure not only helps to maintain the Group's good reputation but also fosters a fair competitive business environment, ensuring that commercial interactions with suppliers adhere to ethical and legal standards. The Group has achieved a 88% signatory coverage rate for the Integrity Commitment Letter, further securing the integrity and honesty foundation of our cooperative relationships. We aim to build a fair and transparent business ecosystem through these measures, laying a solid foundation for long-term, mutually trusting partnerships.

Green Procurement Policy

As a responsible enterprise, Wilson Engineering pays high attention to the potential environmental impacts of its supply chain and is committed to continuously enhancing its environmental management standards. In the procurement of raw materials and products, we adhere to prioritising environmentally friendly materials or products that save energy, water, and materials, such as high-efficiency motors, to minimise negative environmental impacts to the greatest extent possible. We value the green and low-carbon performance of our suppliers. During the Year, in the supplier evaluation stage, we awarded bonus points to suppliers holding green carbon emission certificates. Regarding project environmental compliance, we rigorously select equipment suppliers for desulfurisation, denitrification, wastewater treatment, and similar areas, and actively promote the adoption of recyclable, environmentally friendly packaging materials. Within contract technical agreements, we clearly require suppliers to provide products that are energy-efficient, environmentally friendly, and safe. Simultaneously, in packaging standards and marking clauses, we strictly stipulate that packaging materials must comply with national environmental regulations, prohibiting the use of any materials that may pollute the environment. Furthermore, we prioritise establishing long-term cooperative relationships with suppliers that emphasise social responsibility, jointly promoting the development of a green supply chain, and clearly stipulating environmental and social responsibility requirements in standard contract templates. In the transportation phase, by optimising logistics solutions, such as adopting efficient models like centralised procurement, we reduce transportation costs and energy consumption, thereby implementing the concept of green supply chain management. We are dedicated to building an environmentally friendly and efficient supply chain system in support of the harmonious development of the environment and society.

Communication and Cooperation with Suppliers

Wilson Engineering places high importance on communication and collaboration with suppliers, and is committed to ensuring precise alignment of needs and expectations between both parties and building stable cooperative relationships. To achieve this objective, we support suppliers in enhancing their production and operational capabilities through targeted training and guidance, strengthening their supply stability and efficiency. Simultaneously, strengthening communication mechanisms enables us to more effectively identify and prevent potential supply chain risks on the supplier side, further enhancing the overall management level of the supply chain. We aim to establish mutually trusting and beneficial partnerships with suppliers, thereby jointly promoting efficient and stable supply chain operations.

We firmly believe that systematic human resource management is key to unlocking talent potential and value.

We strictly comply with relevant labour and employment laws and regulations, such as the Labour Law of the People's Republic of China, the Labour Contract Law of the People's Republic of China, and the Social Insurance Law of the People's Republic of China, and have established a fair, equitable, and open talent selection system. The Group, through the Provisions on Employee Recruitment Management, optimises its human resource allocation, standardising processes such as recruitment requisition application and posting, interview and hiring criteria, onboarding, and probationary period confirmation, ensuring the fairness and efficiency of recruitment activities. We have formulated the Employee Handbook, clearly stipulating internal policies and operational procedures to ensure employee adherence to human resource-related policies and codes of conduct. We are convinced that building a regulated and fair workplace environment provides solid protection for the mutual growth of employees and the enterprise.

5. NURTURING EMPLOYEE DEVELOPMENT

During the recruitment process, Wilson Engineering rigorously verifies the identity documents, relevant certifications, and work experience of applicants. We require employees to sign an Offer Acceptance and Commitment Letter, prohibiting false statements, submission of fraudulent materials, concealment of facts, and other such acts. Any discovered violations will result in the revocation of the employment offer. The Group resolutely prohibits the hiring of child labour. For any identified loopholes, we promptly initiate investigations and implement corrective measures to prevent the recurrence of similar incidents. We have established clear working hours and rest period systems, firmly opposing any form of forced labour. When signing labour contracts, we adhere to the principles of legality, fairness, mutual consultation, consensus, and good faith, clearly stipulating working hours and schedules. When overtime work outside the stipulated schedule is required for job duties, employees must complete an overtime application form in advance, stating the reason and duration, and obtain approval from the relevant supervisor before it is considered authorised. Authorised overtime is compensated in accordance with relevant legal provisions. The Group continuously refines its management systems, formulating reasonable compensation based on employees' qualifications, positions, and pay scales, ensuring that employees' salary, benefits, and leave entitlements are effectively safeguarded through regulated management. Through these measures, we are dedicated to fostering a fair and transparent workplace environment, providing employees with reliable support and protection.

Freshmen Gathering, Sailing Ahead — Wison Engineering 2025 Graduates Training Camp

In August 2025, Wison Engineering conducted a 4-day induction camp at its Shanghai headquarters for 40 newly recruited university graduates from Shanghai, Beijing, and Zhengzhou. The camp, featuring lectures from senior executives and a core "instructor team", systematically covered the entire project management and design lifecycle, core HSE concepts, corporate culture, and business etiquette. Activities such as the "Nazca Giant Painting" and team presentations strengthened collaboration and creativity. The new graduates also participated in field study trips to the Nantong base and an FLNG project site, deepening their understanding of core business operations and safety compliance. An incentive points system and a closing ceremony with awards enhanced their sense of belonging and achievement. This induction programme consolidates human capital, strengthens safety governance, and provides talent assurance for sustainable development.

Wilson Engineering not only focuses on training new recruits but also places high importance on its existing frontline, middle, and senior management. Consequently, Wilson Engineering has established the following training systems and programmes for management at each level:

Frontline Management
The Group conducts the Project Manager and Designated Project Manager Training Programme (biannually), as well as the Design Manager Training Programme. The talent pools for project managers and design managers are continuously expanding, serving as centralised hubs for the job rotation and cultivation of the Company’s various outstanding cadres. These programmes aim to enhance the professional competencies and leadership capabilities of project and design management.
Middle and Senior Management
During the Reporting Period, we provided leadership training for middle and senior management. The content focused on cultivating management capabilities and core competencies for this level, aiming to comprehensively refine and bolster their leadership and professional skills.
Senior Management
We promote the Company’s Master-level technical training. In collaboration with technical departments, we have established annual, regular knowledge-sharing and training sessions for Company-level Associate Chief Engineers and Professional-level Associate Chief Engineers on the Wilson Academy platform. These sessions are designed to elevate the professional capabilities and knowledge levels of technical personnel.

Through these measures, we are committed to enhancing employees’ professional skills and providing a robust platform for career development. Furthermore, the systematic talent cultivation mechanism and active promotion of corporate culture further strengthen our competitiveness.

Career Progression Paths

We provide employees with three primary career progression channels to facilitate their professional development. These channels are the technical, management, and project management paths. Firstly, on the technical track, employees can progress from Assistant Engineer to Fellow Engineer. The Company encourages employees to obtain relevant professional certifications annually, providing learning opportunities and incentive policies. Secondly, the management track allows employees to advance from entry-level positions into managerial roles. Finally, the project management track encourages employees to develop from an engineering role into positions such as Reviewer, Design Manager, or Project Manager. These channels offer employees diverse growth opportunities.

Wison Engineering is committed to achieving the organic integration of position, performance, and remuneration by building a comprehensive incentive system based on job role, competency, and performance. We govern compensation management based on market positioning, job value evaluations, and assessments of employee capability and performance, ensuring fair and equitable salary distribution. Employees' performance and role adjustments directly influence changes to their job grade. The job grade promotion mechanism incentivises employees to continually enhance their professional capabilities, with outstanding performers receiving corresponding compensation rewards. Concurrently, job grade and corresponding salary scales are adjusted in line with role changes and modifications to job responsibilities. We conduct annual evaluations of employees' job grades and salaries. Through clear incentive mechanisms and reasonable assessment criteria, we ensure that the efforts and contributions of every employee are fully recognised, thereby strengthening team cohesion and overall performance.

To support the achievement of the enterprise's strategic objectives, the Group has established a career development system, offering two parallel career development paths: the "Professional Technical" path and the "General Management" path. The Professional Technical path is designed for all technical professionals, covering multiple fields such as design, procurement, and construction management, with a focus on deepening and accumulating specialised skills. The General Management path targets personnel in management roles, focusing on project management and administration, aiming to achieve business objectives through motivation and resource allocation. Employees can alternate between the two paths, enabling comprehensive planning of their individual careers. We believe that providing employees with clear growth paths can effectively support the alignment of their professional success with corporate goals.

5.3 CARING FOR EMPLOYEE BENEFITS

We have always regarded our employees as the core driving force of the enterprise's development, highly valuing their contributions and committed to providing full recognition. We continuously focus on the physical and mental well-being of our employees and their diverse professional and personal needs, striving to create a healthy and safe working environment to safeguard their welfare. Simultaneously, we emphasise the importance of communication. By establishing open communication channels, we actively listen to employees' opinions and needs and provide timely feedback. The Group values employees' opinions and contributions, and actively implements measures to improve the working environment. Through the establishment of smooth communication mechanisms, we proactively listen to employees' views and requirements. The Group aims to build a platform that supports employee growth and well-being, creating favourable conditions for the mutual success of the enterprise and its employees.

Communication and Engagement

We consistently respect employees' voices and proactively listen to their suggestions. Through multi-channel communication mechanisms, we actively listen to employees' recommendations and opinions, building an effective bridge between management and staff. We advocate for open and transparent communication to promote teamwork, enhance work efficiency, and increase employee job satisfaction, fostering a harmonious and trusting workplace atmosphere. The Group is committed to reducing misunderstandings in information transmission to ensure communication accuracy. Simultaneously, by establishing communication channels based on mutual respect and support, we ensure that the perspectives and talents of every employee are fully expressed and showcased, thereby driving the effective implementation of solutions. We strive to create an open and inclusive workplace environment, supporting the mutual growth of employees and the enterprise.

Top-Down Communication	Bottom-Up Communication	Two-Way Communication
To ensure employees efficiently grasp the enterprise's development philosophy and strategic decisions, we adhere to a practice where all departments receive directives from senior management and subsequently disseminate and reinforce these messages through departmental meetings. Simultaneously, the Wilson official WeChat account and corporate website periodically interpret management decisions to strengthen corporate information communication capabilities.	To enable senior management to gain a more authentic and detailed understanding of frontline employees' needs and perspectives, we launched the "Issues Concerning Wilson People" initiative on the Wilson platform. This campaign collects topics of concern and requests raised by frontline employees. Through forums such as the New Year Symposium and All-Staff Meetings, we facilitate face-to-face dialogue between both parties, enhancing employees' sense of belonging and effectively addressing their questions and challenges.	Minutes from management's weekly meetings are also uploaded to the website, ensuring every employee is promptly informed of the Company's strategy and various project progress, and can also provide personal feedback to their superiors.

The following outlines Wilson Engineering's employee communication channels:

Online Channels	Offline Channels
Internal publications, official WeChat account, online employee surveys, distribution of meeting minutes	Performance reviews, all-staff meetings, graduate and all-employee symposiums, team-building activities, departmental regular meetings

We rigorously enforce national, provincial, and municipal labour protection policies, improving various social insurance schemes for employees. This includes the timely and full payment of pension insurance, medical insurance, unemployment insurance, work injury insurance, maternity insurance, and the housing provident fund for active staff. We also implement multiple assistance measures, such as enterprise annuity and employer's liability insurance, for eligible employees. For employees engaged in work with high occupational disease risks, in addition to social security, we provide additional commercial insurance to protect their personal safety during work. Concurrently, we have established an annuity plan for all employees, specifically tailored to the actual cost and budget situation, allowing for more flexible approval in the face of special circumstances compared to previous years. We consistently extend New Year greetings to employees working away from home during the holiday season and their families, expressing our gratitude and care for them.

Employee Care

We prioritise employees' physical and mental health. In addition to arranging annual health check-ups, we have also established an employee psychological counselling service platform to provide considerate support for mental well-being. We organise health-themed lectures for employees, imparting knowledge on health maintenance and tips for preventing common illnesses. We are committed to supporting employees in achieving a harmonious balance between their professional and personal lives through diversified initiatives. We actively organise various employee activities, such as sports meets, knowledge competitions, and family days, to help employees relieve work-related stress and cultivate a healthy, positive mindset. These activities not only enhance team vitality and cohesion but also promote communication and collaboration among employees, thereby fostering the enterprise's health and sustainable development. We believe that by actively organising relevant employee activities, we can foster a vibrant and supportive workplace atmosphere, providing strong support for the comprehensive development of employees and the harmonious progress of the enterprise.

During the event, the project team also held environmental lectures at the construction site, reinforcing employees' understanding of practical operational standards such as water conservation and dust control, and recognised staff members for their outstanding environmental contributions. Through this series of practical initiatives, the project team translated the concept of green development into tangible action, demonstrating the environmental commitment and social responsibility of a Chinese enterprise.

6. CO-CREATING FOR A BETTER SOCIETY

Practising Public Welfare and Charity, Warming Hearts at Shanghai Baby Home

On 19 March 2025, a team of Wison Engineering volunteers visited the "Shanghai Baby Home" to conduct the "Walking with Wison, Loving Our Children" public welfare activity. Through the donation of supplies and interactive companionship, they integrated ESG principles into tangible action, providing warm care to support children in need, extending the corporate mission of "Better Technology, Better Future" into the realm of public service.

Prior to the event, employees actively responded to the donation drive, contributing books, puzzles, picture books, and toys to add knowledge and joy for the children. We also prepared daily necessities such as shoes, hats, health products, milk, and hand cream based on actual needs, offering practical support for the children's everyday lives. The "Sunflower Volunteers" team, composed of cultural ambassadors, trade union committee members, and employee representatives, acted on the original intention of "Guarding Life, Growing Towards the Sun", conveying hope through concrete actions.

On the day of the event, volunteers organised a "Miniature Landscapes, Grand Visions" eco-friendly bottles workshop, accompanying the children in creating ecological micro-landscape handicrafts, fostering their environmental awareness and hands-on skills through the creative process. Finally, adults and children danced together, filling the air with laughter and the warmth of shared joy. This charitable initiative not only brought happiness to the children but also allowed the volunteers to gain a sense of fulfilment and personal growth through their contributions.

Walk with Wison for Good: The EGG Walkathon Concludes Successfully

On 10 May 2025, as a steadfast practitioner on the path of public welfare, Wison Engineering actively responded to the call of philanthropy by participating in the large-scale charity walk "The EGG Walkathon". Through fundraising by walking, the event provides comprehensive support in health, education, and psychological well-being for children aged 0-18, helping them grow up healthy and achieve equal development.

Prior to the event, a wave of philanthropic enthusiasm had already swept through Wilson Engineering. Employees proactively formed two energetic teams with a total of 12 members. Holding firm to the belief of "Walking with Wison, Setting Off for Good", they measured love with their steps and conveyed warmth through action, jointly contributing to a brighter future for the children. Employees unable to attend in person also generously donated, supporting the cause with tangible actions. In the end, the two Wilson Engineering teams collectively walked 65 kilometres, taking 540,000 steps. Combined personal donations from employees and the corporate donation totalled RMB 60,000, paving a hopeful path for the children's growth.

Wison Engineering Brings Warmth to Sunqiao Nursing Home

On 9 July 2025, Wison Engineering launched an ESG public welfare activity — “A Visit to Sunqiao Nursing Home”. A volunteer team composed of employee representatives and cultural ambassadors from Wison Engineering entered Sunqiao Nursing Home with warmth and care to conduct the charitable donation and visitation activity. Prior to the event, the volunteer team visited the nursing home to understand their needs on the ground. Learning that some air conditioning units were ageing and ineffective, the Group swiftly responded by purchasing and donating units, alleviating the elderly residents’ concerns about the summer heat.

During the event, the volunteers transformed into “Time Catchers”, taking playful photographs of the seniors. With each click of the shutter, beaming smiles were instantly captured, becoming precious memories. The volunteers patiently kept the residents company, helping them select coloured paper and piece together patterns. One by one, artworks full of childlike fun took shape, becoming warm gifts in the hands of the seniors. The entire visit provided the seniors with an unforgettable afternoon. Even graduate trainees unable to attend in person wrote messages of blessing on cards, conveying their well-wishes. This public welfare initiative was not merely a material donation and act of compassionate companionship; it served as a dynamic demonstration of the Company’s commitment to its ESG philosophy, fostering a sense of social responsibility among employees, and conveying the genuine warmth of the enterprise.

Wilson Engineering Honoured as Outstanding Blood Donor Collective; Our Dedication Passes on the Gift of Life

On 2 September 2025, at the Shanghai Pudong New Area Recognition Ceremony for Voluntary Blood Donation and Community Blood Donation Work Summary Meeting, Wilson Engineering was honoured with the title of “Outstanding Collective in the 2024 Shanghai Community and Enterprise Blood Donation Work Assessment”. This honour was a high recognition of Wilson Engineering’s proactive fulfilment of social responsibility and promotion of the volunteer spirit. It was also a vivid testament to the dedication and compassion of every caring Wilson employee who participated in blood donation.

In 2024, a total of 55 Wilson employees enthusiastically participated in voluntary blood donation, contributing a total of 10,000ml of life-saving blood. Among them were both first-time donors, the new forces who rolled up their sleeves, and long-term “model donors” who have persisted for years. All shared the same spirit of dedication, offering strength to life and sustaining hope. This honour belongs to every Wilson Engineering employee who extended an arm to deliver warmth.

Organising voluntary blood donation is one of our key initiatives in practising our ESG philosophy and fulfilling our social responsibility. Moving forward, Wilson Engineering will continue to encourage and support employees’ participation in public welfare causes such as voluntary blood donation. We will persistently explore richer and more diverse paths for corporate responsibility practice, delivering care through concrete actions and creating a brighter future for all.
