Since launching the construction of its Penglai offshore engineering facility in 2010, the Company has steadily
advanced its “second growth curve” — the strategic layout and implementation of its overseas offshore wind
equipment business, which has achieved remarkable results in recent years with a continuous expansion
of European orders. In the reporting year, the Company continued to implement its “Offshore & Overseas
Strategy”, focusing on the high technical standards, stringent quality requirements and high value-added
characteristics of offshore wind markets in developed economies worldwide. We has continuously advanced
the iteration of its markets and products, and steadily enhanced our competitiveness and market share in the
offshore wind markets of major developed economies globally.
Meanwhile, the Company is actively fostering its future “third growth curve” by partnering with international
leading providers of floating foundation solutions, establishing a global floating business center, and
accelerating the R&D and engineering application of a new generation of floating foundation products.
Leveraging our new Panjin facility and the cluster of coastal high-end offshore engineering facilities, the
Company continues to strengthen its in-house vessel manufacturing capacity and specialized transportation
fleet, building a global logistics and delivery network covering major offshore wind markets. It has gradually
developed an integrated solution capability spanning “manufacturing, transportation and delivery”.
With the operation of overseas wind power mother ports, Dajin Heavy Industry has formally established a
full industrial chain closed-loop featuring “self-owned factories, self-owned cargoes, self-owned vessels
and self-owned ports”. This has laid a solid foundation for the Company to deepen its presence in the deep-
water offshore market, improve cross-regional project delivery efficiency and risk control capabilities, and
develop comprehensive EPCI service capabilities. It has also significantly enhanced the Company’s systematic
competitive advantages in the global high-end offshore wind market.
Since 2023, the Company has firmly implemented the "New Overseas & Offshore Strategy". With the
continuous expansion of its overseas business share, its leading position in the global industry has become
increasingly consolidated. Overseas offshore engineering products have become the core engine driving
the improvement of the Company’s profitability. Particularly in the European offshore wind market with high

Double Materiality Assessment
Dajin Heavy Industry regards materiality assessment as a key foundation for sustainability management. In 2025, the Company conducted its
first systematic assessment in accordance with the double materiality principle, with reference to the relevant requirements of the Shenzhen
Stock Exchange’s Self-Regulatory Guidelines for Listed Companies No. 17 – Sustainable Development Report (for Trial Implementation)
and Self-Regulatory Guidelines for Listed Companies No. 3 – Preparation of Sustainable Development Reports.
The Company identified a long list of topics through internal and external stakeholder surveys, conducted quantitative analysis from the two
dimensions of financial materiality and impact materiality, and finally formed a double materiality matrix, providing a decision-making basis
for annual actions and strategy integration.

Comprehensive planning of shipping industry
In the context of the global energy structure accelerating its transition towards
cleaner and lower-carbon forms, offshore wind power, as an important pillar of
renewable energy, is experiencing unprecedented development opportunities.
Since 2023, Dajin Heavy Industry has been proactively planning for the shipping
sector, focusing on overseas markets and concentrating on offshore wind power
products. The Company has launched the "New Off-shore & Overseas " strategy,
aiming to complete the strategic transformation from "equipment supplier" to
"system service provider". Meanwhile, Dajin Heavy Industry is well aware of the
pain points of the traditional FOB (Free on Board, i.e. "delivery on board the vessel
at the port of loading") model, such as high costs, uncontrollable transportation
capacity and difficulties in controlling carbon emissions. Therefore, the Company
has decisively implemented the cross-border shipbuilding strategy, and completed
the integration of Panjin Shipyard in 2023. As the shipping sector operation
becomes increasingly mature, the Company officially innovatively launched
the DAP (Delivered At Place) one-stop delivery model in 2024, incorporating
the entire chain of product manufacturing, loading at port of loading, ocean
transportation, unloading at port of discharge and etc. into the service system.
In 2025, the Company's representative deck barge M/V KING ONE successfully
launched, marking a milestone breakthrough. Thus, the dual-drive model of
"Ocean-going Specialized Transportation + Ship Design and Construction" has                                                                                                       The “New Off-shore & Overseas”

During the reporting period, the Sustainability Center organized two dedicated climate change training sessions for the Board of Directors, with the aim of continuously enhancing the Board’s professional capabilities on climate-
related matters. The training covered topics including the Net-Zero Industry Act issued by the European Union, the revised CBAM Regulation , and the draft IMO Net-Zero Framework issued by the International Maritime
Organization (IMO). Looking ahead, the Company has planned to provide the Board with ongoing climate-related professional knowledge through various means, including the introduction of external expert support and the
continued delivery of internal thematic training. These efforts are intended to ensure that the Board has access to the necessary professional support to effectively fulfill its responsibilities for the management and oversight of
climate-related matters.
Strategy
We attach great importance to the challenges and opportunities brought about by climate change, and
proactively integrate climate change response into the Company’s overall strategy. With reference to the
recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and international
disclosure frameworks such as IFRS S2 Climate-related Disclosures, the Company systematically identifies
climate-related risks and opportunities and continuously optimizes its responses to key climate risks, thereby
supporting its low-carbon emission transition.
 Scenario Analysis
     To comprehensively understand the potential impacts of climate change on the Company’s business,
     strategy, and financial performance, we adopted a climate scenario analysis approach to conduct
     forward-looking assessments of climate-related physical risks, taking into account the uncertainties in
     both the timing and magnitude of climate change impacts.
     ? Scope: The assessment covered 10 core production and operating sites and major investment
          projects located in Shandong, Hebei, Liaoning, Inner Mongolia, and other regions2. These include
          offshore wind equipment manufacturing facilities, shipbuilding facilities, onshore wind tower
          manufacturing facilities, and renewable energy generation projects.
     ? Time horizons: The assessment is aligned with the time horizons of Dajin Heavy Industry’s carbon
          target setting, namely the current term (2025), the short term (2030), and the long term (2050).
     ? Risk types: The Company identified and assessed seven acute physical risks—river flooding, pluvial
          flooding, storm surge, extreme precipitation, storms, wildfires, and heatwaves—as well as two
          chronic physical risks—drought and heat stress.
     ? Climate scenarios: Using the Shared Socioeconomic Pathways (SSPs) developed by the
          Intergovernmental Panel on Climate Change (IPCC), the Company selected two scenarios—a
          low-emissions scenario (SSP1-2.6) and a high-emissions scenario (SSP5-8.5)—and conducted

Energy Management
Dajin Heavy Industry regards energy management as an important lever for advancing its low-carbon strategy and improving operational
efficiency. By strengthening management systems, improving energy utilization efficiency, and optimizing the energy mix, the Company
systematically promotes the green transformation of energy use throughout its production and operations, and continuously reduces energy
consumption and carbon emissions intensity per unit of product.
 Energy Management System
The Company strictly complies with laws and regulations such as the Energy Law of the People’s Republic of China and the Energy
Conservation Law of the People’s Republic of China , while benchmarking against internationally advanced energy management standards
and continuously advancing the development of its energy management system. In accordance with the ISO 50001 Energy Management
System standard , the Company has established and continuously improved a management system covering energy planning, operational
control, monitoring and analysis, and continuous improvement. It has formulated and implemented institutional documents such as the
Energy Management Manual, Control Procedure for Monitoring and Measuring Equipment, Control Procedure for Energy Targets,
Indicators and Management Programs, and Energy Operation Control Procedure , thereby clarifying energy management responsibilities
and operating processes and promoting the standardized and institutionalized operation of energy management. During the reporting
period, the Company’s Penglai Facility officially obtained ISO 50001 Energy Management System certification, marking that the Company
has met international standard requirements in areas such as energy management system development, energy performance monitoring,
and continuous improvement mechanisms. Looking ahead, the Company will gradually expand the coverage of energy management system
certification, extend its systematic management experience to more production bases and business units, and continuously strengthen the
foundation of its energy management.
 Advancing Energy Efficiency Improvement
Following the establishment of its SBTi emissions reduction and net-zero targets in 2025, the Penglai Facility continued to strengthen full-
process energy use management and reinforce energy control measures across production and manufacturing, equipment operation, and
day-to-day office operations, thereby systematically promoting energy efficiency improvement. First, based on the energy management
policy, the Company formulated annual energy consumption control targets, decomposed these targets level by level, and established
clear energy consumption goals, forming an energy management target system with well-defined responsibilities. Second, it continuously
improved its energy metering and monitoring mechanisms, established a multi-dimensional energy monitoring and data statistics
system, and carried out real-time monitoring and data analysis of major energy consumption such as electricity and natural gas, thereby
continuously enhancing the accuracy of energy data statistics and analytical capability and providing data support for energy-saving
management decisions. At the same time, taking into account the characteristics of production and operations, the Company established
an energy performance assessment mechanism, under which quota management standards were set for electricity, natural gas, and other
energy use in production workshops and office areas. Special analyses and improvement measures were implemented for any usage
exceeding the quota, driving all units to continuously improve energy utilization efficiency. In terms of equipment management, the
Company formulated equipment energy efficiency management standards, requiring that newly procured equipment should, as a priority,
meet China’s Grade 1 energy efficiency standard, and developed phased phase-out and upgrade plans for old, high-energy-consuming
equipment. Through equipment renewal and technological upgrading, the Company continues to reduce overall energy consumption.
Systematic energy management and continuous technological improvement will be progressively deepened across the Company’s facilities,
and Dajin Heavy Industry will continue to enhance energy utilization efficiency at all facilities, providing solid support for the achievement of
its carbon reduction targets and green manufacturing transformation.

Green Steel Management
Green steel is a core strategic material for wind power equipment manufacturing, and its low-carbon emission attributes directly determine the carbon footprint of
wind power products across their full life cycle. Dajin Heavy Industry has proactively positioned itself in green steel supply chain management, actively responding to
international carbon barriers and promoting emissions reduction practices from the very beginning of the industrial chain, thereby leading the industry’s green upgrading
through pragmatic actions.
 Management Structure
Dajin Heavy Industry has established a Green Steel Special Committee and a Green Steel Task- Force to systematically advance the development of its green steel
business. The Committee is responsible for coordinating the strategic direction of green steel and the Company’s carbon competitiveness enhancement objectives. The
Task-Force is led by a Sponsor, with the leader responsible for overall coordination and organization. Core members come from departments including the Sustainable
Development Center, Supply Chain Management Center, and Overseas Business Division, forming a cross-functional working mechanism with clear responsibilities and
authorities. Based on this structure, the Company promotes internal research on the application of low-carbon steel technologies while externally coordinating customer
and supplier needs, thereby providing organizational support for the implementation of green steel products.

Circular Economy
We actively practice the core philosophy of "circular regeneration", and continuously improve the level of
comprehensive resource utilization. By building a closed-loop recycling system for internal production waste,
and working with suppliers to explore reuse pathways in the procurement process, the Company promotes
the conversion of various types of waste into resources, thereby systematically reducing resource waste and
environmental impact.
During the reporting period, each production facility actively explored practices for resource recycling. We not
only carry out remanufacturing and reuse of production surplus materials and waste, but also implement the
circular concept throughout the whole process of tooling management: we consider the subsequent reuse
potential at the design phase to ensure cross-project compatibility; at the application phase, we actively
explore models such as the shared use of storage and construction tooling, which effectively improves the

 Talent Recruitment and Retention
Dajin Heavy Industry closely aligns its talent acquisition strategy with business development needs by establishing a diversified recruitment system. This system is centered on proprietary recruitment channels, supplemented
by external sources, and reinforced by specialized pipelines for talent reserves. The Company utilizes a variety of channels, including public online recruitment platforms, internal talent mapping and headhunting, international
executive search firms, and employee referral programs. Over the reporting period, more than 1,000 new hires were onboarded, achieving precise segmentation and efficient replenishment across all talent levels. This robust
approach provides strong support for the ongoing optimization of the Company’s talent structure and the development of talent pipelines.

Labor Rights Management
Dajin Heavy Industry is committed to human rights protection and safeguarding employee rights, adhering to the Labor Law of the People’s Republic
of China and referencing the eight core conventions of the International Labour Organization (ILO). The Company has established a comprehensive
management system integrating policy development, internal audit optimization, and training empowerment. Policies and action guidelines are
formulated for each site, and implementation is driven through social responsibility management system procedures. Targeted training is conducted
to promote compliance awareness, supported by social responsibility evaluation metrics and assessment methods, with ongoing enhancements in
research and internal audit practices. By piloting at key bases and covering core business units and critical positions across the group, Dajin advances
the implementation of human rights policies, incorporating extensive industry best practices, cost analysis, and internal auditing. This approach
delivers dual benefits: strengthening employee rights protection and ensuring compliant corporate operations.

Employee Promotion and Training
 Job Grade System and Promotion Selection
Dajin Heavy Industry’s job grade system is built on the core principles of standardized management, streamlined career pathways, and value alignment, establishing a layered and categorized dynamic mechanism
that enables both upward and downward mobility, fully embodying the “people-oriented” philosophy. The system encompasses four major tracks: management, technical, professional, and operational, implementing
a dual career path for management and professional technical development to meet diverse talent growth needs. Job grades are divided into 15 levels, ranging from Grade 10 to Grade 24. The management track is
further segmented into senior, middle, and frontline management, with clear responsibilities and transparent promotion criteria.This system is deeply integrated with compensation, performance appraisal, training, and
leadership selection, ensuring equitable development opportunities for employees and stimulating organizational vitality. Following optimization in 2025, the system further enhances career diversity and inclusiveness,
providing employees with a clear career development roadmap and facilitating both personal value realization and the Company’s sustainable growth.
