“Launching The Sao Vang CPP”

MESSAGE CHAIRMAN FROM THE

““By identifying, continuously assessing risks, and managing fluctuations, PTSC has actively innovated and seized business opportunities in the energy transition trend. This has led to the development of new products, expanded participation in tenders, and increased involvement in offshore renewable energy projects, helping to offset the declining traditional business volume experienced over the past period”

Dear Shareholders,

From the second half of 2022 through the end of 2023, domestic businesses continued to face numerous difficulties in production and operation. The number of businesses exiting the market was significantly higher compared to the same period last year. The decline in credit absorption capacity led to slower credit growth. The decrease in investment demand and resilience clearly demonstrated the extent of difficulties faced by the businesses in 2023. The global oil and gas industry was also facing significant fluctuations and challenges, including supply chain disruptions, the impact of global conflicts, and the ongoing energy transition from fossil fuels to cleaner, greener alternatives, driven by global and regional commitments. Amid the challenging domestic and international landscape, the development of new exploration projects to boost domestic reserves faced significant hurdles, resulting in delays and setbacks. The intense competition from private companies for the dwindling traditional business volume has further compounded the challenges. Moreover, the sharp fluctuations in fuel prices, raw materials, transportation costs, and input goods and services have had a profound impact on the production and business operations of PTSC and its subsidiaries. By identifying, continuously assessing risks, and managing fluctuations, PTSC has actively innovated and seized business opportunities in the energy transition trend. This has led to the development of new products, expanded participation in tenders, and increased involvement in offshore renewable energy projects, helping to offset the declining traditional business volume experienced over the past period. PTSC has successfully exceeded its 2023 business plan targets, achieving consolidated revenue of 21,742 billion VND and consolidated profit before tax of 1,277 billion VND, representing 165% and 164% of the annual plan, respectively. Notably, the company’s overseas service revenue accounted for over 55% of total revenue in 2023, a significant increase compared to previous year, highlighting efforts of PTSC’s employees, their determination and adaptability to sustain growth. The positive results of 2023 have solidified PTSC’s position, stature, and brand in the energy market. This achievement is a testament to PTSC’s spirit of enthusiasm, aspiration, and its ability to adapt to challenges and transform in a dynamic environment. Through proactive measures such as actively seeking new opportunities, implementing comprehensive solutions, and driving business development, PTSC has successfully navigated through difficult times and strengthened its overall capabilities. The company’s active participation in the energy transition and renewable energy sector, coupled with its commitment to resolving challenges, has led to improved business performance and ensured the protection of the interests of the State, Shareholders, and Employees, thereby

contributing to PTSC’s sustained growth and stability.

In 2024, the oil and gas industry is expected to have promising outlook, driven by positive oil prices and the accelerated FID approval process in June 2024 for major upstream projects (Block B O Mon, Su Tu Trang - phase 2B, Lac Da Vang) as well as the ongoing LNG electrification transition. With a strong culture of legal compliance, prioritizing collective interests and project success, and fostering unity, collaboration, and growth, along with the guidance and support of higher authorities and PVN, coupled with the company’s accumulated experience and development, PTSC’s leadership, executives, and employees are unwavering in their commitment to successfully completing the 2024 business plan assigned by the GMS and higher authorities. They are determined to ensure the full and harmonious protection of the legitimate rights and interests of the State, shareholders, and employees.

On behalf of the Board of Directors, I would like to express my deepest gratitude to the Board of Management, executives and employees of PTSC for their contributions, dedication, efforts, and hard work. I would also like to express my most sincere thanks to the government agencies, Shareholders, Corporation, Investors, Clients and Partners who have always accompanied, trusted, cooperated and supported us and I wish you good health, happiness and new successes in 2024 and beyond.

CHAIRMAN

Dear Shareholders,

As usual, with each Annual General Meeting, PTSC’s Annual Report is sent to you. For us, this report is more than just a document or a financial statement for our esteemed shareholders. It is a significant publication that summarizes and provides comprehensive information about PTSC’s operations, business activities, and performance over the past year. This publication also serves as a platform for PTSC to showcase its corporate image and culture, while reaffirming our commitment to transparency and accountability to our shareholders, partners, and customers. These elements have contributed to building and strengthening the trust of investors over the years.

With the release of the 2023 Annual Report, a detailed picture of PTSC’s operations throughout the year was revealed. Celebrating its 30th Anniversary, a significant milestone, PTSC took the opportunity to reflect on and celebrate its remarkable journey. 2023 was not only a year to celebrate PTSC’s achievements, foundation, culture, and values over 30 years of development but also a year to further solidify the corporate position and brand reputation. It was a year of complete success and one that opened up many new opportunities for PTSC.

Ladies and gentlemen,

Following a period of struggle, PTSC has successfully rebounded, with its 2023 revenue propelling the Corporation back into the “20 trillion VND arena”. The Corporation has successfully exceeded all production and business targets. In the traditional oil and gas services sector, the PTSC brand continued to be strengthened and affirmed.

PTSC also made a significant mark in the offshore renewable energy sector. From the early signs a few years ago, PTSC quickly transformed new opportunities into action, making significant strides in new sectors. This led to the signing and implementation of numerous service contracts. PTSC made a remarkable leap with a total of $1.5 billion in orders for offshore renewable energy projects. PTSC’s manufactured products were exported to many markets worldwide. We saw a surge in customers actively reaching out to us. Having navigated the challenges of the post-crisis period and difficult times of work scarcity, PTSC achieved a significant milestone by securing contracts that provide job security until 2027.

PTSC’s position and stature in the new arena has made fresh progress, with the PTSC brand growing stronger each day.

This is also the collective achievement of PTSC’s united, dynamic, and creative workforce.

Ladies and gentlemen,

In order to successfully implement the plans of 2024 and beyond, PTSC would need to pursue new objectives, including in traditional oil and gas services and offshore renewable energy. This would require a flexible approach, restructuring, and a strong focus on improving productivity, capacity, and resource efficiency through lean manufacturing, lean management, and lean thinking.

With passion, enthusiasm, belief, and drive, fueled by the energy and experience of our 20 years, we are committed to standing shoulder to shoulder, striving to achieve greater heights and ensuring sustainable and stable success. The PTSC team remains united in our mission to sustain and expand our business operations, implement a variety of service solutions to ensure revenue, profitability, and a sustainable dividend stream, thereby maintaining the trust of investors and shareholders and realizing PTSC’s future vision, mission, and strategic goals.

For our valued shareholders and investors, PTSC remains committed to the highest standards of professionalism, transparency, efficiency, and commitment. We strive to be recognized as one of the best listed companies and to earn your continued trust.

We wish you good health, happiness, luck and success.

Sincerely!

PRESIDENT & CEO

BUSINESS PERFORMANCE REPORTS IN 2023

1.

“Completed the offshore installation of Hai Thach PQC Central Processing Platform – Bien Dong Project.”

2023 PERFORMANCE OVERVIEW

Background

In 2023, the global macroeconomic environment and international markets continued to face numerous challenges, complex fluctuations, and unpredictable uncertainties due to the prolonged Russia-Ukraine military conflict and more recently, the emergence of the Israel-Hamas conflict in the Middle East. These events negatively impacted cross-border supply chains of goods and services, increasing pressure on global trade and investment. Domestically, amid “dual” challenges both internally and externally, investment in new exploration and production projects and domestic reserve enhancement faced many difficulties and delays. Only by the end of 2023 were there positive signals regarding the implementation of the Block B - O Mon Gas-Power project chain. Sharp fluctuations in fuel prices, raw materials, and transportation costs significantly impacted many of PTSC’s business sectors.

“Hai Long windfarm substation was successfully loaded out and began its cruise to the Taiwan Strait (China).”

2023 PERFORMANCE OVERVIEW

Assessment of production and business performance

Amid numerous challenges and obstacles, PTSC proactively adopted innovations, seized business opportunities in the energy transition trend, and made significant strides into the offshore renewable energy sector including developing new products, expanding the provision of offshore renewable energy services into overseas markets such as the Middle East, India, Taiwan, Malaysia, Brunei, Indonesia, and Thailand, helping to offset the continuous decline in traditional business volumes and achieving a remarkable milestone of $1.5 billion order value in the offshore renewable energy sector. PTSC’s fabrication products have been exported to numerous markets.

After weathering the post-crisis storm and overcoming challenges of work shortage, PTSC has secured long-term contracts, extending until 2027. PTSC’s fabrication products have been exported to numerous markets, and the Corporation witnessed a surge in demand from new clients. This significantly enhanced PTSC’s market position and the PTSC brand is growing stronger day by day.

ASSESSMENT OF BUSINESS PERFORMANCE

A. Consolidated targets

B. Targets for parent company

The recent period has been marked by significant challenges and uncertainties in the global political, macroeconomic, and market environment. These complexities disrupted cross-border supply chains and placed immense strain on global trade and investment. The volume of work and projects related to PTSC’s domestic operations continued to be scarce. The combination of low service prices, intense competition, delays in new exploration and production projects, and the slow progress of the Block B O Mon Gas-Power Project until the end of 2023 significantly impacted PTSC’s business operations.

Faced with these challenges, PTSC’s leadership and employees have implemented decisive management measures and undertaken strong restructuring to boost business development, improve operational efficiency, and taken strict cost-control measures. These efforts enabled PTSC to effectively respond to market fluctuations and maintain safe, efficient, and stable operations. Notably, PTSC has made vigorous efforts to innovate and find new directions and opportunities amid the global green energy transition, particularly as traditional services face growing challenge. PTSC actively engaged with numerous potential partners and clients in the offshore renewable energy sector, leading to the signing of multiple Memoranda of Understanding (MOUs) and Cooperation Agreements to facilitate investment, development and seeking financial solutions for offshore renewable energy projects. To date, PTSC has completed the necessary legal framework and become the only entity within Vietnam National Oil and Gas Group authorized to invest in the offshore renewable energy sector. PTSC is currently working with foreign partners to vigorously develop offshore renewable energy projects serving both domestic and export markets.

The 2023 performance results reflected PTSC’s successful adaptation to industry trends and its ability to capitalize on new opportunities. The consolidated revenue in 2023 reached VND 21,742 billion, up 27% year-on-year and up 47% from 2021. Consolidated profit before tax in 2023 reached VND 1,277 billion, the same as in 2022 and up 32% from 2021.

In particular, PTSC was in charge of all O&M work on some projects. Vessel’s uptime rate reached nearly 100%, higher than required by contracts. Maintaining the provision, management and operation of the floating refrigerated LPG storage vessel Viet Dragon 68 met the client’s requirements. In April 2023, after providing O&M services for the FPSO Lewek Emas, PTSC was awarded a $300,000 bonus by POVO/HE in recognition of its exceeding O&M KPIs. This demonstrated the client’s high level of trust and appreciation for PTSC’s floating storage and offloading operations.

ASSESSMENT OF FINANCIAL PERFORMANCE PTSC

PTSC has achieved higher profitability and improved short-term liquidity, ensuring compliance with PTSC’s financial regulations and industry best practices in financial governance. The low debt ratios, both debt-to-equity and debt-toassets, reflected PTSC’s healthy financial condition. The Corporation’s operations were largely financed by equity, resulting in minimal financial pressure and efficient business operations.

BOD’S ACTION PLAN 2024

2024 is expected to be a breakthrough year in the implementation of the 5-year plan (2021-2025) for both the Vietnamese economy and the Corporation. Domestic oil and gas industry is expected to have a bright outlook due to sustained high oil prices, upstream projects, and the LNG-to-power transition. The international situation continues to experience rapid, complicated and unpredictable developments. The Board of Directors concludes that the Company needs to address the ongoing challenges posed by the intense competition in the oil and gas technical services, projects, and both domestic and international operations. Climate change and global energy consumption have triggered a global shift. Traditional energy projects continued to lose market share and production and development projects slowed. The oil and gas services sector faced intense competition from private companies which possessed a variety of unique competitive advantages including ownership structure, favorable legal environment, and flexibility in investment decisions. In addition, the development of offshore services was difficult due to the low volume of work and the stricter protection of domestic companies by local governments...

MARKET RISK

Identification of risks

Amid integration, Vietnam remains vulnerable to risks due to its transitioning economy, small size, and limited resilience to external shocks. However, since 2020, Vietnam has shown “moderate-to-good” resilience and has been one of the few economies to sustain positive economic growth.

The year 2023 was marked by significant global economic challenges, characterized by persistent geopolitical tensions, rising protectionism, tense competition among great powers, and tightening of monetary policies by central banks worldwide to curb inflation, resulting in adverse effects on economic and social activities... In light of the aforementioned impacts, the oil and gas market has undergone following significant fluctuations:

Demand for oil and gas surged in nearly almost all regions to meet global economic growth.

However, this rising demand was hampered by a global supply shortage caused by sanctions and production cuts from major producing countries. In April 2023, OPEC+ members announced voluntary production cuts of 1.16 million barrels per day until the end of 2023, while the UAE also declared a 144,000 barrels per day cut for the mid-2023 period. Additionally, the oil embargo on Russia has significantly reduced global oil supply, destabilizing the global energy market in general and the oil and gas market in particular.

In the domestic market, crude oil production has steadily declined in recent years due to the absence of major upstream projects. The gas supply also experienced a sharp decline in output, particularly from low-cost sources. Instead, natural gas production was primarily sourced from higher-cost fields such as Thien Ung, Dai Hung, Sao Vang – Dai Nguyet, PM3 – Ca Mau sourced from Malaysia.... However, the oil and gas market experienced growth in 2023 due to investments in new oil and gas projects.

MARKET RISK

Management measures

Synchronize the implementation of formulated solutions, focus on optimizing resources, promote services along the value chain based on advantages of scale and multi-service business, and emphasize core services.

Continuously innovate and improve to increase capabilities and competitiveness, as well as consider and develop new services and clients; conduct research and investment and execute onshore projects to complement business activities in addition to ongoing offshore projects;

Maintain the corporate culture throughout PTSC; Improve corporate governance by applying advanced management principles and practices from around the world;

Innovate recruitment, training and employment processes and align employee interests with PTSC’s growth.

A notable change in the investment and bidding legal framework in 2023 was the introduction of a new Bidding Law. Accordingly, second-tier enterprises affiliated with state-owned economic groups, were significantly impacted, both as investors and contractors.

In addition to creating a fair and equitable bidding environment for both domestic and foreign entities, the new Bidding Law has also tightened the regulations on bidding procedures, conditions, and competitive elements. In an increasingly challenging market for traditional oil and gas services, domestic companies would be forced to compete fiercely with their foreign “players” when bidding for contracts.

For investors, the reduced scope and application of the Bidding Law will promote greater adaptability and competitiveness in the market, enabling them to seize more business opportunities. On the other hand, it also means that the Investors would bear greater responsibility for investment activities, procurement, and contractor selection. Once they are no longer subject to the application, companies would be more proactive and flexible. Management at all levels within the company would face increased responsibilities and greater pressure. Therefore, PTSC must develop its own regulations for investment, procurement, and contractor selection to meet the specific requirements of its business operations while ensuring efficiency and compliance with general regulations.

The upstream segment of the oil and gas industry has seen a significant progress in terms of production growth and new field development. Block B-O Mon Gas-Power Project has officially entered the implementation phase. In 2023, the Government issued the Decree No.45/2023/ND-CP detailing the Petroleum Law and other enacted guiding documents. The oil and gas industry continued to advocate for policies that create a favorable legal framework for oil and gas exploration and production, field development, propose the approval of solutions to remove difficulties and challenges in ongoing domestic projects.

Despite this, the legal framework for offshore investment in the oil and gas sector remains inadequate. Additionally, Vietnam currently does not have specific and clear regulations that can create technical barriers to safeguard domestic production and increase the competitiveness of domestic service providers. Foreign contractors are at an advantage to participate in the

provision of oil and gas services in Vietnam, leading to increased competition for domestic counterparts.

In line with the energy transition trend and the commitment to Net-Zero carbon emissions by 2050, the government is gradually implementing its strategy to develop offshore renewable energy, particularly, offshore wind power as a new marine economy. Vietnam Oil and Gas Group is also developing a comprehensive sustainable development strategy until 2045 with a focus on technological innovation and energy transition. After the initial phase, PTSC has deeply involved in the offshore renewable energy market with the aim of becoming a project developer and investor, and has already secured contracts totaling US$1.5 billion in offshore renewable energy. To date, PTSC has been able to successfully implement all the phases of offshore renewable energy development. In 2023, PTSC was granted approval by the Ministry of Natural Resources and Environment to conduct monitoring, survey, and assessment activities of marine resources to serve the projects to export offshore wind power to Singapore. Notably, PTSC has received strong support from the government and relevant ministries for its investment project to export electricity to Singapore in cooperation with Sembcorp Utilities Ltd. The project has been approved by the Energy Market Authority of Singapore (EMA).

Last year, the government promulgated the National Power Development Plan for the period 2021-2030, with a vision to 2050. The government has also outlined a strategy to amend a number of legal sectors and, concurrently, while initiating research, development, and issuance of regulations on renewable energy. The development of mechanisms and policies to encourage domestic enterprises to participate in the development of renewable energy, renewable energy industry, new energy for consumption at home and abroad, development of electrical equipment manufacturing industry, and acceleration of onshore and offshore wind power, including pilot application of power purchase agreements, have been put on the table for discussion. However, at the macro level, the offshore renewable energy development policies have not yet been translated into specific legal documents, or codified into law. Mechanisms for offshore renewable energy development remain incomplete and lack a comprehensive legal framework. Incentive policies to encourage domestic investment in project development have not received adequate attention.

POLICY RISK

Management measures

In its production and business activities, PTSC has always ensured compliance with general laws. PTSC has also made necessary adjustments to ensure compliance with new regulations, industry development trends, PTSC’s specific areas of operation and governance requirements.

In addition, PTSC has strengthened controls, established a decentralized management mechanism for investment and procurement, and increased individual and collective accountability. PTSC has also developed and reinforced its internal mechanisms for decentralization, authorization, assignment of tasks, reporting, monitoring, auditing, internal evaluation, and internal control... The internal regulatory system has been developed in a comprehensive, consistent, and rigorous manner, resulting in high efficiency.

Furthermore, PTSC maintains its adherence to all the regulations applicable to public companies, ensuring transparency, accountability and under the scrutiny of shareholders, the board of control and and competent levels (GMS, BOD).

Given the diverse range of services provided in a closed-loop chain across multiple sectors, continuous and diversified investments, procurement of materials and equipment, PTSC has promptly reviewed and revised its procurement and investment regulations and procedures in compliance with the Bidding Law while ensuring competitiveness, transparency, timeliness, and efficiency.

PTSC also continues to focus on reviewing, updating and improving the system of internal management documents to ensure compliance with legal regulations, and to provide a solid legal basis for management and administration: Regulations on risk management, legal and regulatory compliance procedures, payment and prepayment, postproject material management...

In addition, PTSC continues to educate, disseminate in legal regulations, provide training in legal aspects, participate in the formulation of legal policies, actively provide opinions on relevant legal documents, including those related to the draft Decree guiding the Petroleum Law and the draft Bidding Law, the Decree guiding the Bidding Law, the Circulars on the provision and publication of information on the bidding and selection of contractors on the national bidding network and the formulation of laws on renewable energy...

In 2024, PTSC will keep improving the system of internal regulations, restructuring its functional divisions, completing the mechanisms for decentralization, authorization, and assignment. In addition, PTSC will continue to educate and disseminate legal regulations in various ways, participate in the formulation of legal policies, actively contribute opinions on legal documents, and propose policies to facilitate PTSC’s business growth at home and abroad and in non-oil sectors, submitting proposals to competent authorities regarding special mechanisms for oil and gas services.

For the offshore renewable energy sector, PTSC will propose to the Government, relevant authorities in promptly issuing detailed plans as well as amending and supplementing certain applicable legal documents in order to create a favorable legal corridor and environment for companies like PTSC to develop projects, export services, construction works and products in the offshore renewable energy sector in line with the guidelines and policies of the State. Accordingly, the relevant legal documents must be fully developed, not only Law on Renewable Energy, Law of the Sea, but also related legal sectors (Electricity, Oil and Gas, Investment...), technical standards, specialized and professional guidance documents, investment procedures, evaluation, and selection of investors.

In the meantime, PTSC also recommends that while a comprehensive policy framework for offshore renewable energy is still being developed, the Government should introduce temporary measures to enable qualified companies to pilot projects under special arrangements.

FINANCIAL RISK

Identification of risks

Credit risk: arises when a client or partner fail to perform their contractual or debt payment obligations, resulting in financial loss to PTSC.

Interest rate risk: PTSC has mobilized capital from domestic and international credit institutions to meet its investment and business operation needs, therefore, there is an interest rate risk.

Exchange rate risk: PTSC’s customers and suppliers come from different geographical areas and most of them involve foreign elements, so the revenue in foreign currency accounts for a significant proportion and, as a result, there is always an exchange rate risk.

Liquidity risk: PTSC operates in a diverse range of businesses involving significant investments in assets such as floating vessels, service vessels, port facilities, lifting equipment, as well as requiring substantial working capital for services like mechanical manufacturing, thereby creating an inherent liquidity risk.

FINANCIAL RISK

Risk management

PTSC has consistently identified financial risks and put forward appropriate mitigation measures, and made continuous improvements year-on-year, specifically:

Regarding credit risk, before participating in a bidding package or implementing any contract, PTSC evaluates the financial position and operation of its customers and partners to ensure the feasibility of contract performance and develop an appropriate credit policy. Periodically, PTSC performs debt reconciliation, assessment of credit history and send letters of confirmation and notices to remind the customers and partners of debt payment. For those with high credit risk, PTSC will require payment guarantee from a reputable credit institution or the parent company.

Regarding interest rate risk, PTSC has mobilized capital from domestic and international capital markets in both domestic and foreign currencies to diversify its capital sources and avoid sudden impacts from one market. In addition, to minimize risks from interest rate fluctuations, PTSC has raised capital, performed derivative transactions to fix interest rates and maintain a reasonable level of fixed and floating interest rate loans.

Regarding exchange rate risk, PTSC has adopted a balanced foreign exchange revenue and expenditure policy as a mitigation measure by matching the contracts signed with customers with the amount payable to suppliers. In addition, PTSC has employed derivative instruments such as currency swaps and forward contracts... to manage foreign currency flows and increase financial returns.

Regarding liquidity risk, PTSC has implemented specific regulations and procedures to maintain tight control over cash flow for each project, work, and contract. Receivables are always collected before payables are due. Long-term assets are financed with long-term capital.

HEALTH, SAFETY, QUALITY AND ENVIRONMENT RISKS

Identification of risks

In a world of disruption, globalization and technological breakthroughs, risk management has become more complex and critical than ever. Technology offers new opportunities, but it also creates risks that cannot be overlooked.

PTSC has come to understand that risk management cannot simply be a reactive measure, but must be closely aligned with business strategy. If PTSC limits itself to simply reacting to risks, it may not be able to respond effectively to real-time challenges and could end up incurring unnecessary compliance costs without delivering real effectiveness.

Management measures HEALTH, SAFETY, OCCUPATION,

To mitigate risks related to occupational health, safety, environment, and quality, PTSC has developed a comprehensive risk management system (RMS) based on the principle of protecting and enhancing the values aligned with PTSC’s objectives, action plans, and business operations, ensuring balance between costs, benefits and objectives.

AND QUALITY RISKS

In 2023, PTSC issued its Risk Management Policy on February 01, 2023, and Risk Management Regulations on May 16, 2023. PTSC is currently working to further develop a unified Risk Management System across PTSC to achieve its strategic objectives.

In parallel with the development of the Risk Management System, PTSC is implementing a range of solutions, including investments in infrastructure, equipment, human resources, management systems, technological innovation, digitalization, and digital transformation, to enhance its competitiveness in core business areas in compliance with current regulations. PTSC is also pursuing and committed to enhancing its capabilities in the design, fabrication, construction, installation, operation, and maintenance of offshore renewable energy projects.

In the coming period, PTSC is dedicated to pursuing comprehensive risk management to ensure agility and adaptability to unforeseen changes and maintain an appropriate risk level to capitalize on investment opportunities and growth. Risk management measures are regularly monitored and evaluated to ensure their effectiveness, efficiency, and compliance with legal requirements, while achieving business objectives and meeting the expectations of shareholders and stakeholders.

SUSTAINABLE DEVELOPMENT REPORT

1.

“Cảng PTSC Thanh Hóa”

OVERVIEW OF SUSTAINABLE DEVELOPMENT

The energy transition is progressing vigorously worldwide, with a shift towards renewable energy sources to ensure each country’s energy security and collectively address pressing issues such as climate crisis, aiming at net-zero carbon emissions by 2050, as committed by the Government of Vietnam at COP26.

Based on the similarities in the service chains of oil and gas projects and offshore renewable energy (ORE) projects, PTSC has many advantages that enable it to deeply participate in the supply chain for ORE projects regionally and globally. Since 2022, PTSC has made several strategic changes in its production approach, gradually shifting and expanding its production model from single/oneoff production to mass and lean production—high-volume, highefficiency manufacturing. This represents a completely different closed-loop production process compared to traditional oil and gas projects. In addition, PTSC has strengthened its investment to upgrade equipment and facilities, reorganize and reallocate space, and expand the fabrication yard area at the Vung Tau Downstream Port (currently the largest fabrication yard in the region); organize numerous specialized training programs for the workforce across all member units and subsidiaries; promote and expande strategic

partnership collaborations domestically and internationally; and especially, continue to contribute in coordination with the authorities of Ba Ria – Vung Tau Province to promoting collaboration and investment opportunities towards developing Ba Ria – Vung Tau into a ORE center in Vietnam and the region.

Regarding the operational orientation for 2024 and the coming years, PTSC will focus all its resources on successfully implementing the signed contracts for the Block B Gas Project and ORE projects. This includes conducting surveys for the ORE project to export clean electricity to Singapore with the goal of starting power generation by 2033, contributing to the orientation of the Vietnam Oil and Gas Group and other enterprises in building a “Green Energy Economy” for Vietnam and the region. In collaboration with local authorities, PTSC will strengthen regional linkages to promote the development of the Southern Key Economic Zone. The Corporation continues to accelerate the development of the ORE supply chain, rapidly establish a renewable energy hub in the south in line with the Power Development Master Plan VIII issued by the Government. This effort supports the Government’s goal of achieving net-zero emissions by 2050, as committed by Vietnam at the COP26 Conference.

SUSTAINABLE DEVELOPMENT GOALS

PVS STOCK REVIEW

The market records a dramatic rebound in 2023

After a turbulent 2022, the VN-Index witnessed a spectacular recovery in 2023, thanks to the government’s proactive measures to support the economy and the stock market. The VN-Index started at 1,007,09 points in the beginning of 2023 and gradually recovered throughout the year, reaching a peak of 1,243.14 points in early September 2023. Despite a market decline in October, the VN-Index rebounded to 1,129.93 points on December 29, marking a 12.2% increase from the beginning of the year.

On average, global oil prices declined by 17% in 2023 compared to 2022, after reaching an all-time high in March 2022. However, oil prices showed positive signs in the second half of 2023, driven by OPEC+’s efforts to cut production to balance supply and demand, and geopolitical tensions in the Red Sea region also impacted the prices. Since then, the oil prices have gradually recovered with the average price in the second half of 2023 increasing by 6% compared to the first half. The increase in oil prices in the second half of 2023 provided a modest boost to the performance and share prices in the oil and gas sector. In 2023, PVS experienced a 78% increase in share price compared to the beginning of the year.

Oil and gas industry in 2024: Global demand is expected to grow, with many key domestic projects anticipated to accelerate in implementation

The global oil and gas industry outlook for 2024 continues to be strong and stable, supported by high oil prices and growing demand. According to the International Energy Agency (IEA), the U.S. Energy Information Administration (EIA), and OPEC, oil demand growth in 2024 is expected to continue at a rate of 1.4 million barrels per day from the already high base in 2023 (exceeding pre-COVID-19 consumption level). These organizations also gave a forecast that the average price of Brent crude will reach USD 82 per barrel in 2024, maintaining stability compared to 2023, thanks to rising demand and OPEC+’s production cuts. Along with this price level, the countries worldwide will continue to explore and develop new oil and gas projects, driving economic growth. This will create positive prospects for oil and gas technical service providers like PVS.

In Vietnam, following the successful approval of the Lac Da Vang oil field project in 2023, a framework agreement for the Nam Du - U Minh gas field was signed in early 2024. It is highly likely that Vietnam Oil and Gas Group and its international partners will make a final investment decision on several key oil and gas projects, such as the Block B O Mon gas field and the Su Tu Trang - Phase 2B projects, boosting domestic oil and gas production and creating opportunities for upstream oil and gas companies such as PVS, PVD, GAS...

In addition, in line with the trend of green energy transition, offshore renewable energy projects have become increasingly attractive and rapidly developed worldwide. PVS has become a pioneer by participating in offshore wind power projects in Taiwan. Despite some challenges, the global offshore wind industry is still forecast to experience a strong double-digit growth. Therefore, PVS is perfecting its value chain to become a critical link in the global offshore wind industry and aims for a multi-billion-dollar backlog. As an investor in the Offshore Renewable Energy project, PVS secured the Conditional Approval from the Singaporean government in October 2023. In particular, PVS will act as a joint investor and developer in the clean energy export project to Singapore, starting in 2030. PTSC and its partner Sembcorp have outlined a detailed roadmap, from surveying, investment planning, and developing offshore wind farms in Vietnam, to producing and exporting approximately 1.2GW of clean energy from Vietnam to Singapore via a high-voltage submarine cable. As an EPC contractor for Offshore Renewable Energy (ORE) projects, PVS has been actively investing in facilities and infrastructure to leverage its strengths and develop into a new supply chain in Vietnam for large-scale ORE projects in the Asia-Pacific region. PVS has won tenders, executed mechanical works, and provided services for a wide range of offshore wind projects, including those from global ORE giants like Orsted, CIP, Equinor, Elektrownia Wiatrowa Baltica, Swancor Holding Company, Enterprise Energy..., and continued to actively participate in the bidding processs of their projects.

STATEMENT BY THE BOARD OF MANAGEMENT

Responsibility of the Board of Management in respect of the Consolidated Financial Statements

The Board of Management of PetroVietnam Technical Services Corporation (“the parent Company”) is responsible for preparing the consolidated financial statements of the parent Company and its subsidiaries (together, “the Corporation”) which give a true and fair view of the consolidated financial position of the Corporation as at 31 December 2023 and the consolidated results of its operations and its consolidated cash flows for the year then ended. In preparing these consolidated financial statements, the Board of Management is required to:

• Select suitable accounting policies and then apply them consistently;

• Make judgments and estimates that are reasonable and prudent; and

• Prepare the consolidated financial statements on a going concern basis unless it is inappropriate to presume that the Corporation will continue in business..

The Board of Management of the Corporation is responsible for ensuring that proper accounting records are kept which disclose, with reasonable accuracy at any time, the consolidated financial position of the Corporation and which enable consolidated financial statements to be prepared which comply with the basis of accounting set out in Note 2 to the consolidated financial statements. The Board of Management of the Corporation is also responsible for safeguarding the assets of the Corporation and hence for taking reasonable steps for the prevention and detection of frauds or errors.

Approval of the Consolidated Financial Statements

We hereby approve the accompanying consolidated financial statements as set out on pages 5 to 91 which give a true and fair view of the consolidated financial position of the Corporation as at 31 December 2023 and the consolidated results of its operations and its consolidated cash flows for the year then ended in accordance with Vietnamese Accounting Standards, the Vietnamese Corporate Accounting System and applicable regulations on preparation and presentation of consolidated financial statements.

On behalf of the Board of Management

Ho Chi Minh City, SR Vietnam 12 March 2024

INDEPENDENT AUDITOR’S REPORT

TO THE SHAREHOLDERS OF PETROVIETNAM TECHNICAL SERVICES CORPORATION

We have audited the accompanying consolidated financial statements of PetroVietnam Technical Services Corporation (“the parent Company”) and its subsidiaries (together, “the Corporation”) which were prepared on 31 December 2023 and approved by the Board of Management on 12 March 2024. These consolidated financial statements comprise the consolidated balance sheet as at 31 December 2022, the consolidated income statement and the consolidated cash flow statement for the year then ended, and explanatory notes to the consolidated financial statements, as set out on pages 5 to 91.

The Board of Management’s Responsibility

The Board of Management is responsible for the preparation and the true and fair presentation of these consolidated financial statements in accordance with Vietnamese Accounting Standards, the Vietnamese Corporate Accounting System and applicable regulations on preparation and presentation of consolidated financial statements and for such internal control which the Board of Management determines as necessary to enable the preparation and fair presentation of the consolidated financial statements that are free from material misstatements, whether due to fraud or errors.

Auditor’s Responsibility

Our responsibility is to express an opinion on the consolidated financial statements based on our audit. We conducted our audit in accordance with Vietnamese Standards on Auditing. Those standards require that we comply with ethical standards and requirements and plan and perform the audit in order to obtain reasonable assurance as to whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, including an assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal controls relevant to the Corporation’s preparation and true and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Corporation’s internal controls. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by the Board of Management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Auditor’s Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Corporation as at 31 December 2023, its consolidated financial performance and consolidated cash flows for the year then ended in accordance with Vietnamese Accounting Standards, the Vietnamese Corporate Accounting System and applicable regulations on preparation and presentation of consolidated financial statements.

Other Matters

The report on review of consolidated financial information is prepared in Vietnamese and English. Should there be any conflict between the Vietnamese and English versions, the Vietnamese version shall take precedence.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.1 Basis of preparation of consolidated financial statements

The consolidated financial statements have been prepared in accordance with Vietnamese Accounting Standards, the Vietnamese Corporate Accounting System and applicable regulations on preparation and presentation of consolidated financial statements. The consolidated financial statements have been prepared under the historical cost convention and on a going concern basis except for investments in associates and joint ventures and business combinations as presented in Note 2.5, and the basis of accounting for PTSC Labuan Company Limited’s and PTSC CGGV’s financial statements on liquidation basis as presented in Note 1.

The accompanying consolidated financial statements are not intended to present the consolidated financial position and consolidated results of operations and consolidated cash flows in accordance with accounting principles and practices generally accepted in countries and jurisdictions other than Vietnam’s. The accounting principles and practices utilised in Vietnam may differ from those generally accepted in countries and jurisdictions other than Vietnam.

The consolidated financial statements in the Vietnamese language are the official statutory consolidated financial statements of the Corporation. The consolidated financial statements in the English language have been translated from the Vietnamese version.

2.2 Fiscal year

The Corporation’s fiscal year is from 1 January to 31 December. The consolidated financial statements are prepared for the fiscal year from 1 January to 31 December.

2.3 Currency

The consolidated financial statements are measured and presented in Vietnamese Dong (“VND”).

The Corporation determines their accounting currencies based on the currencies which are mainly used in sales of goods and rendering of services, which have a significant impact on selling prices of goods and services, which are normally used to list selling prices and receive payments; which are mainly used in purchases of goods or services, which have a significant impact on cost of labour, materials, merchandise, and other production or operating costs and normally used as payments for those costs.

Additionally, the Corporation also uses these currencies to raise financial resources and/or regularly collects these currencies from business operation and savings.

On consolidating, if the currencies used in the components’ financial statements are different from that of the parent Company, the Corporation is required to translate those financial statements into the currency used in the Corporation’s consolidated financial statements under the following principles

• Assets and liabilities are translated at actual exchange rate at the end of the reporting year;

• Owners’ capital is translated at the exchange rate of contribution date;

• Net assets of those acquired companies are translated at the exchange rate of acquisition date;

• Undistributed earnings or accumulated losses incurred after acquisition date are translated based on the translation of income and expenses in the income statement;

• Profits and dividends already paid are translated at the actual exchange rate at the date of payment;

• Items of the income statement and the cash flow statement are translated at the average exchange rate of the accounting period if it approximates the actual rate at the time of the transaction;

• The accumulative amount of exchange differences arising from translation is presented in a separate component of owners’ equity of the consolidated balance sheet. For subsidiaries, accumulated exchange differences attributable to the parent Company are presented in “Foreign exchange differences” and those attributable to non-controlling interests are allocated to “Non-controlling interests”; and

• Upon disposal, the accumulated exchange difference relating to translation of these companies’ financial statements presented in owners’ equity of the consolidated balance sheet is recognised as financial income or financial expense in the same reporting year.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.4 Exchange rates

Transactions arising in foreign currencies are translated at exchange rates ruling at the transaction dates. Foreign exchange differences arising from these transactions are recognised in the consolidated income statement.

Monetary assets and liabilities denominated in foreign currencies at the consolidated balance sheet date are respectively translated at the buying and selling exchange rates at the consolidated balance sheet date of the commercial bank(s) where the Corporation regularly trades. Foreign currencies deposited in commercial bank(s) at the consolidated balance sheet date are translated at the buying exchange rate of the commercial bank(s) where the Corporation opens its foreign currency accounts. Foreign exchange differences arising from these translations are recognised in the consolidated income statement.

2.5

Basis of consolidation

Subsidiaries

Subsidiaries are all entities over which the Corporation has the power to govern the financial and operating policies in order to gain future benefits from their activities generally accompanying a shareholding of more than one half of the voting rights. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Corporation controls another entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Corporation. They are de-consolidated from the date that control ceases.

The purchase method of accounting is used to account for the acquisition of subsidiaries by the Corporation. The cost of an acquisition is measured as the fair value of the assets given, equity instruments issued and liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date, irrespective of the extent of any non-controlling interest. The excess of the cost of acquisition over the fair value of the Corporation’s share of the identifiable net assets acquired is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognised directly in the consolidated income statement.

In a multi-phase acquisition, when determining goodwill or bargain purchase, the consideration is the sum of the total consideration on the date of acquiring control and previous considerations remeasured to fair value on the date of control acquisition.

Inter-company transactions, balances and unrealised gains and losses on transactions between group companies are eliminated.

Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Corporation.

The financial statements of the Corporation’s subsidiaries are prepared for the same accounting period. If there are differences in end dates, the gap must not exceed 3 months. Adjustments are made to reflect impacts of significant transactions and events occurring between the end dates of the subsidiaries’ fiscal year and that of the Corporation’s. The length of the reporting year and differences in reporting date must be consistent between years.

Non-controlling transactions and interests

The Corporation applies a policy for transactions with non-controlling interests as transactions with external parties to the Corporation.

Non-controlling interests (“NCI”) are measured at their proportionate share of the acquiree’s identifiable net assets at date of acquisition.

Transactions leading to the change in the Group’s ownership interest in a subsidiary that does not result in a loss of control is accounted for as a transaction with owners. The difference between the change in the Corporation’s share of net assets of the subsidiary and any consideration paid or received from divestment of Corporation’s interest in the subsidiary is recorded directly in the undistributed earnings or accumulated losses under equity.

Transactions leading to the change in the Group’s ownership interest in a subsidiary that results in a loss of control, the difference between the Corporation’s share in the net assets of the subsidiary and the net proceeds from divestment is recognised in the consolidated income statement. The retained interest in the entity will be accounted for as either an investment in other entity or investment to be equity accounted for since the divestment date.

Joint ventures and associates

A joint venture is a contractual agreement by two or more parties to jointly conduct an economic activity, which is jointly controlled by the joint venture capital partners. Associates are investments that the Group has significant influence but not control over and the Group would generally have from 20% to less than 50% of the voting rights of the investee. Investments in joint ventures and associates are accounted for using the equity method of accounting and are initially recognised at cost. The Group’s investment in joint ventures and associates includes goodwill identified on acquisition, net of any accumulated impairment loss.

The Group’s share of the post-acquisition profits or losses of its joint ventures and those of its associates is recognised in the consolidated income statement. The cumulative post-acquisition movements are adjusted against the carrying amount of the investment. When the Group’s share of losses in a joint venture or associate equals or exceeds its interest in the joint venture or associate, the Group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the joint venture or associate.

Accounting policies of joint ventures and associates have been changed where necessary to ensure consistency with the policies adopted by the Corporation.

Unrealised gains and losses on transactions between the Group and its joint ventures and associates are eliminated to the extent of the Group’s interest in the joint ventures and associates.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(Continued)

Cash and cash equivalents comprise cash on hand, cash in banks, demand deposits, cash in transit, and other short-term investments with an original maturity of three months or less, which are highly liquid and readily convertible to known amounts of cash and subject to an insignificant risk of changes in value at the date of the consolidated financial statements.

2.7 Receivables

Receivables represent trade receivables arising from sales of goods and rendering of services or non-trade receivables and are stated at cost. Provision for doubtful debts is made for each outstanding amount based on overdue days in payment according to the initial payment commitment (exclusive of the payment rescheduling between parties), or made for each outstanding amount that is not overdue but doubtful and so the Corporation may be unable to collect the debts. Bad debts are written off when identified according to current prevailing accounting regulations and the Corporation’s finance management policies.

Receivables are classified into long-term and short-term receivables on the consolidated balance sheet based on the remaining period from the consolidated balance sheet date to the collection date.

2.8 Inventories

Inventories are stated at the lower of cost and net realisable value. Cost is determined by the weighted average method and includes direct materials, direct labor costs, overhead expenses, purchase cost, and other costs incurred in bringing the inventories to their present location and condition. Net realisable value is the estimated selling price in the normal course of business, less the estimated costs of completion and selling expenses such as publicity, selling and distribution expenses.

The Corporation applies the perpetual system for inventories.

Provision is made for obsolete, slow-moving and defective inventory items. The difference between the provision of this year and the provision of the previous year are recognised as an increase or decrease of cost of goods sold in the year.

Inventories are classified as short-term and long-term on the consolidated balance sheet based on the plan for use in production and business activities of the Corporation at the date of the consolidated balance sheet.

2.9 Investments

(a) Investments held to maturity

Investments held to maturity are investments which the Corporation has positive intention and ability to hold until maturity.

Investments held to maturity include bank term deposits and other held-to-maturity investments. Those investments are initially accounted for at cost and measured at acquisition price plus directly attributable transaction costs. Post-acquisition interest income from investments held to maturity is recognised in the consolidated income statement on accrual basis. Pre-acquisition interest is deducted from the cost of such investments at the acquisition date.

Provision for diminution in value of investments held to maturity is made when there is evidence that the investment is uncollectible in whole or in part. Changes in the provision balance during the fiscal year are recorded as an increase or decrease in financial expenses. A reversal, if any, is made only to the extent the investment is restored to its original cost.

Investments held to maturity are classified into short-term and long-term investments held-to-maturity on the consolidated balance sheet based on remaining period from the consolidated balance sheet date to the maturity date.

(b) Investments in other entities

Investments in other entities are investments in equity instruments of other entities without controlling rights or co-controlling rights, or without significant influence over the investee. These investments are accounted for initially at cost. Subsequently, the Board of Management reviews all outstanding investments to determine the amount of provision to recognise at the year end.

Provision for diminution in value of investments in other entities is made in accordance with current prevailing accounting regulations and current accounting policies when there is a diminution in value of the investments at the period/year end. Regarding investments in listed shares or those whose fair value can be determined reliably that the Corporation plans to invest in long-term, the provision for diminution in value is made when cost is higher than its expected recoverable amount. For other investments, provision for diminution in value is made when the investees make losses. Changes in the provision balance during the accounting period/fiscal year are recorded as an increase or decrease in financial expenses. A reversal, if any, is made only to the extent the investment is restored to its original cost.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.10 Construction contracts

A construction contract is a contract specifically negotiated for the construction of an asset or a combination of assets that are closely interrelated or interdependent in terms of their design, technology and functions or their ultimate purpose of use.

When the outcome of a contract can be estimated reliably, and the contractor is paid in accordance with the planned schedule, contract revenue and contract costs are recognised over the period of the contract as revenue and expenses, respectively by reference to the stage of completion of the contract activity at the end of the reporting period, regardless of progress billings and how much it is billed. The Corporation uses the percentage of completion method to determine the appropriate amount of revenue and costs to be recognised in the fiscal year. The percentage of completion is measured by reference to the proportion of actual contract costs incurred to date to the estimated total costs of each contract, except where this would not be representative of the stage of completion. Variations in contract work, claims and incentive payments are included to the extent that they have been agreed with the customer. Where it is probable that total contract costs will exceed total contract revenue, the expected loss is recognised as an expense immediately.

When the outcome of a construction contract cannot be reliably estimated, contract revenue is recognised to the extent of contract costs incurred where it is probable those costs will be recoverable. Contract costs are only recognised when incurred during the year.

The aggregate of the costs incurred and the profit or loss recognised on each contract is compared against the progress billings up to the year end. Where costs incurred and profits recognised (less recognised losses) exceed progress billings, the balance is presented as receivables for construction contracts-in-progress. Where progress billings exceed costs incurred plus recognised profits (less recognised losses), the balance is presented as payables for construction contracts-in-progress.

When the outcome of a contract can be estimated reliably and the contractor is paid for the works performed and certified by the customer, contract revenue and contract costs are recognised in the period for the works performed and certified by customer in the year and reflected in the billed invoices

2.11 Fixed assets

Tangible and intangible fixed assets

Fixed assets are stated at historical cost less accumulated depreciation or amortisation. Historical cost includes expenditure that is directly attributable to the acquisition of the fixed assets bringing them to their suitable conditions for their intended use, in which the historical costs of purchased fixed assets comprise their purchase prices and any directly attributable costs of bringing the assets to their suitable conditions for their intended use. In regard fixed assets formed from construction investment by contractual mode or self-construction or self-generating process, the historical costs are the settled costs of the invested construction projects in accordance with the prevailing State’s regulations on investment and construction management, directly-related expenses and registration fee (if any). In the event the construction project has been completed and put into use but the settled costs thereof have not been approved, the historical cost is recognized at the estimated cost based on the actual cost incurred. The estimated cost will be adjusted according to the settled costs approved by competent authorities. Expenditure incurred subsequently which has resulted in an increase in the future economic benefits expected to be obtained from the use of fixed assets, can be capitalised as an additional historical cost. Otherwise, such expenditure is charged to the consolidated income statement when incurred.

Depreciation and amortisation

Fixed assets are depreciated and amortised using the straight-line method so as to write off the historical cost of the fixed assets over their estimated useful lives. The estimated useful lives of each asset class are as follows:

Buildings and structures

Machinery and equipment

Transport and transmission vehicles

Office equipment

Other tangible fixed assets

Software

Land use right

Other intangible fixed assets

Land use rights are comprised of land use rights with a definite useful life are recorded in accordance with the terms indicated in the land use rights certificate issued by Department of Planning and Investment of Ho Chi Minh City on 29 December 2006 and amortised using the straight-line method over 50 years in accordance with such land use rights certificate.

Definite land use rights are stated at costs less accumulated amortisation. Costs of land use rights consists of its purchased prices and any directly attributable costs in obtaining the land use rights. Land use rights are amortised using the straight-line basis over the terms of the land use right certificates.

Indefinite land use rights are states at costs and not amortised.

Disposals

Gains or losses on disposals are determined by comparing net disposal proceeds with the carrying amount of the fixed assets and are recognised as income or expense in the consolidated income statement.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.11 Fixed assets (continued)

Construction in progress

Construction in progress represents the cost of assets in the course of construction for production, rental or administrative purposes, or for purposes not yet determined, including construction costs, costs of tools and equipment, construction consulting expenditures, and capitalised borrowing costs for qualifying assets in accordance with the Corporation’s accounting policies. In the event of the construction project has been completed and put into use, these expenses will be capitalized to the historical cost of fixed assets at the estimated cost based on the actual cost incurred (in case the settled costs have not been approved). According to the State’s regulations on investment and construction management, the settled costs of completed construction projects are subject to approval by appropriate level of competent authorities. The final costs of these completed construction projects may vary depending on the final approval by competent authorities.

Depreciation of these assets, on the same basis as other fixed assets, commences when they are ready for their intended use.

2.12 Operating leases

Leases where a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the consolidated income statement on a straight-line basis over the term of the lease.

2.13 Investment properties

The historical cost of an investment property represents the amount of cash or cash equivalents paid or the fair value of other consideration given to acquire the investment property at the time of its acquisition or completion of construction. Expenditure incurred subsequently which has resulted in an increase in the expected future economic benefits from the use of investment properties can be capitalised as an additional historical cost. Otherwise, such expenditure is charged to the consolidated income statement when incurred.

Depreciation

Investment properties are depreciated under the straight-line method to write off the historical cost of the assets over their estimated useful lives. The estimated useful lives of investment properties are as follows:

Infrastructure 48 - 49 years

Disposals

Gains or losses on disposals are determined by comparing net disposal proceeds with the carrying amount of investment properties and are recognised as income or expense in the consolidated income statement.

Prepaid expenses include short-term and long-term prepayments on the consolidated balance sheet. Short-term prepaid expenses represent prepayments for services; or tools that do not meet the recognition criteria for fixed assets for a period not exceeding 12 months or a business cycle from the date of prepayment. Long-term prepaid expenses represent prepayments for services; or tools, which do not meet the recognition criteria for fixed assets for a period exceeding 12 months or more than one business cycle from the date of prepayment. Prepaid expenses are recorded at historical cost and allocated on a straight-line basis over their estimated useful lives.

Prepayments for land rental contracts which are effective after the effective date of the land law 2003 (ie. 1 July 2004) or which land use right certificates are not granted are recorded as prepaid expenses and allocated using the straight-line basic over the terms of such land use right certificates.

Classifications of payables are based on their nature as follows:

• Trade accounts payable are trade payables arising from purchase of goods and services; and

• Other payables are non-trade payables and not relating to purchases of goods and services.

Payables are classified into long-term and short-term payables on the consolidated balance sheet based on remaining period from the consolidated balance sheet date to the maturity date.

2.16 Borrowing

Borrowings include borrowings from banks, related parties and third parties.

Borrowings are classified into long-term and short-term borrowings on the consolidated balance sheet based on their remaining period from the consolidated balance sheet date to the maturity date.

Borrowing costs that are directly attributable to the construction or production of any qualifying assets are capitalised during the period of time that is required to complete and prepare the asset for its intended use. In respect of general-purpose borrowings, a portion of which is used for the purpose of construction or production of any qualifying assets, the Company determines the amount of borrowing costs eligible for capitalisation by applying a capitalisation rate to the weighted average expenditure on the assets. The capitalisation rate is the weighted average of the interest rates applicable to the Company’s borrowings that are outstanding during the period, other than borrowings made specifically for the purpose of obtaining a qualifying asset. Other borrowing costs are recognised in the consolidated income statement when incurred.

2.17 Accrued expenses

Accrued expenses include liabilities for goods and services received in the year but not yet paid due to pending invoice or insufficient records and documents. Accrued expenses are recorded as expenses in the reporting year. The recognition of accrued expenses is determined based on the present obligation, which is determined reliably at the time of payment.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(Continued)

2.18 Provisions for liabilities

Provisions are recognised when the Corporation has a present legal or constructive obligation as a result of past events that the Corporation is obliged to settle this obligation, it is probable that an outflow of resources will be required to settle the obligation, and the amount has been reliably estimated. Provision is not recognised for future operating losses.

Provisions are estimated on the amount of money which may be required to settle the obligation. If the time value of money is material, provision will be measured at the present value using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognised as a financial expense. Changes in the provision balance during the fiscal year are recorded as an increase or decrease in operating expenses.

2.19 Unearned revenue

Unearned revenue mainly comprises the amounts that customers paid in advance for one or many accounting periods for leasing assets and related services accompanied the assets. The Corporation records unearned revenue for the future obligations that the Corporation has to fulfill. Once recognition criteria have been satisfied, unearned revenue will be recognised as revenue in the consolidated income statement to the extent that it has met the recognition criteria.

Unearned revenue is classified into short-term and long-term on the consolidated balance sheet according to the portion of obligations that are satisfied for revenue recognition as at the consolidated balance sheet.

• The percentage of completion of the transaction at the consolidated balance sheet date can be measured reliably; and

2.24 Financial expenses

Current and deferred income tax

Income taxes include all income taxes which are based on taxable profits including profits generated from production and trading activities in other countries with which the Socialist Republic of Vietnam has not signed any double taxation agreement. Income tax expense comprises current income tax expense and deferred income tax expense.

Current income tax is the amount of income taxes payable or recoverable in respect of the current year taxable profits at the current year tax rates. Current and deferred tax should be recognised as an income or an expense and included in the profit or loss of the year, except to the extent that the tax arises from a transaction or event which is recognised, in the same or a different year, directly in equity.

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. Deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of occurrence affects neither the accounting nor the taxable profit or loss. Deferred income tax is determined at the tax rates that are expected to apply to the financial year when the asset is realised or the liability is settled, based on tax rates that have been enacted or substantively enacted by the consolidated balance sheet date.

Deferred income tax assets are recognised to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilised.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same tax authority and the Corporation intends to settle its current tax assets and liabilities on a net basis.

The determination of the tax currently payable is based on the current interpretation of tax regulations. However, these regulations are subject to periodic variation and their ultimate determination depends on the results of the tax authorities’ examinations.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(Continued)

2.28 Related parties

Enterprises and individuals that directly, or indirectly through one or more intermediaries, control, or are controlled by, or are under common control with the Corporation, including holding companies, subsidiaries and fellow subsidiaries are related parties of the Corporation. Associates and individuals owning, directly or indirectly, an interest in the voting power of the Corporation that gives them significant influence over the Corporation, key management personnel, including Board of Management, Board of Directors of the Corporation and close members of the family of these individuals and companies associated with these individuals also constitute related parties.

In considering the related party relationship with each related party, the Corporation considers the substance of the relationship not merely the legal form.

2.29 Segment reporting

A segment is a component which can be separated by the Corporation engaged in sales of goods or rendering of services (“business activity segment”), or sales of goods or rendering of services within a particular economic environment (“geographical segment”). Each segment is subject to risks and returns that are different from those of other segments. A reportable segment is the Corporation’s business segment.

Segment reporting is prepared and presented in accordance with accounting policies applied to the preparation and presentation of the Corporation’s consolidated financial statements in order to help users of consolidated financial statements understand and evaluate the Corporation’s operations in a comprehensive way.

2.30 Critical accounting estimates

The preparation of consolidated financial statements in conformity with Vietnamese Accounting Standards, the Vietnamese Corporate Accounting System and applicable regulations on preparation and presentation of consolidated financial statements requires the Board of Management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements; and the reported amounts of revenues and expenses during the financial year.

The areas involving significant estimates and assumptions are:

• revenue and cost of sales relating to construction contracts-in-progress (Note 2.10, 2.22, 2.23); and

• receivable and payable relating to construction contracts-in-progress (Note 2.10).

Such estimates and assumptions are continually evaluated. They are based on historical experience and other factors, including expectations of future events that may have a financial impact on the Corporation and that are believed to be reasonable under the circumstances by the Board of Management.
