SUSTAINABILITY REPORT 2021

SPECIAL REPORT The United Nations has hosted yearly climate conferences since 1995, bringing together representatives fromall around the world to address growing concerns over climate change. Six years ago in Paris, world leaders settled on a global pathway for climate action, committing to keep global warming to 1.5 °C above pre-industrial levels. In 2021, an important outcome at COP26 in Glasgowwas the Global Stocktake that is set to take place every five years. There was a significant step-up in ambitions and critically detailed action plans on emissions reductions from many countries, a display of strengthened solidarity towards safeguarding the planet for future generations. KEY COMMITMENTS FROM COP26 Rapidly scale technologies and policies to transition away from unabated coal power generationby 2030 for major economies and 2040 globally. More than 100 countries agreedto reducemethane, a greenhouse gas 80 times more potent than CO2, by 30% by 2030. 137 countries committed to halt and reverse forest loss and land degradation by 2030. Reaffirmed pledges by developed countries to deliver the US$100 billion yearly in climate financing. GLOBAL DECARBONIZATION AMBITIONS Thailand intends to reduce its Greenhouse Gas (GHG) emissions by 20% by 2030. Europe, through the EU’s ‘Fit for 55’ package, aims to cut emissions by 55% by 2030. The United States aims to cut its GHG emissions in half from 2005 levels by 2030. 1 2 3 4 2 INDORAMA VENTURES PCL.

RISKS IVL is mindful about potential increases in our OPEX to deal with a rise in future environmentbased taxes being introduced globally. Similarly, we predict a rise in CAPEX by investing in green technologies to meet potential changes in environmental legislation and regulations. HOWWE ARE MITIGATING RISKS • CARBON PRICING - We have adopted an internal carbon price that we factor into investment decisions and business plans. Five countries where we operate al ready have carbon pr icing regulations and we expect to see more coverage in the future. • CLEAN ENERGY AND GREEN PROJECTS - We are transitioning towards cleaner sources of energy and decarbonizing our production to reduce emissions from our sites. • DECARBONIZING VALUE CHAIN - Wearemakingprogress throughasustainable supply chainprogramthat prioritizes supplier climate maturity. • EARLY ADOPTION OF NEW DECARBONIZATION TECHNOLOGIES AND SOLUTIONS - Wehavemade inroads towards implementing CarbonCaptureUtilizationandStorage (CCUS) at our site in addition to advanced recycling to drive our circularity efforts. HOWWE ARE UTILIZING OPPORTUNITIES We securedUS$1.3billion in sustainable financing as of the end of 2021 through: - Thailand’s first green loan from Japan’s Mizuho Bank for both US$ 200 mi l l ion and EUR 200 million - A syndicated ESG loan for US$ 255 million arranged by Mizuho Bank. - A blue loan for US$ 300million arranged by the International Finance Corporation (IFC). - Thailand’s largest Sustainability-Linked Bond worth THB 10 billion (~US$ 300 million) These investments will be used to decarbonize our operations and produce low carbon intensive products while also being mindful of customer requirements. Through these proactivemeasures, wewill be able to retain our position and improve our competitiveness as a leading chemical OPPORTUNITIES Climate financing commitments made at COP26 allow us to leverage opportunities in securing financial capital tobetter fundourdecarbonization efforts globally and achieve our sustainability goals. IMPACTS ON IVL As theworldmoves towards these ambitious targets inmitigating climate change, there are areas of improvement that need to be addressed. Public-private partnerships are key in reaching these targets, which is why it is crucial for corporations to step up and declare their commitments to decarbonization. To play our part towards in mitigating climate impacts, we joined more than 90 CEOs of large multinational organizations in signing a recent open letter published by the CEOs Climate Alliance. All signatories are committed to reducing emissions by more than 1Gt annually by 2030 and believe that businesses can do more if world leaders reach an agreement at COP26 that put us on a 1.5 °C pathway. We recognize that undertaking collective efforts will accelerate the decarbonization process. We must continue to apply a carbon lens to everythingwe do, challenge ourselves and push this agenda forward, including at COP27. 3 SUSTAINABILITY REPORT 2021 Responsible Business and Effective Governance Driving Sustainable Value Creation and Growth Towards Net Zero Carbon Empowering Our People and Communities Global Performance Data GRI Standard Content Index

This report outlines IVL’s success in addressing the sustainability and climate issues that matter most to our customers, employees, shareholders, and communities in 2021. IVL is moving quickly on several fronts, and we are driving our actions in line with being responsible, one of our core values. In 2021, we created our purpose statement, ‘Reimagining chemistry together to create a better world,’ which defines our role and the positive impact that we have on our world. ACHIEVING NET ZERO CARBON Last year ’s COP26 in Glasgow ended with a global agreement to accelerate actions on climate change this decade. All countries agreed to strengthen their 2030 emissions targets, known as Nationally Determined Contributions (NDCs), in 2022 to limit global warming to 1.5 °C. So, there is much important work ahead. Our Chief Technology Of f i cers , as par t of the Decarbonizat ion Commi ttee, are heading IVL’s decarbonization strategy. The strategy consists of six prongs to reduce the company’s carbon footprint and support countries where we have operations. The committee provides technical guidance to each of our bus i ne s s s egmen t s and ensu r e s p l an t - l eve l decarbonization efforts to achieve Net Zero Carbon. We are on track to achieve our 2025 goals, and we have set more ambitious 2030 targets. The 2030 targets include a 30% reduction in Scope 1 and 2 combined greenhouse gas (GHG) intensity, 15%reduction in energy intensity, 25%useof renewable electricity, 20%reduction in water intensity, 90% diversion of waste from landfills, recycling 1.5 million tons in PET bale input annually and sustainability capital expenditures of US$ 7 billion. SUSTAINABILITY AT THE FOREFRONT In pursuit of business growth and profitability, we do things the right way – economically, socially, and environmentally. Health and safety are non-negotiable as we implement these three approaches in our global operations. Our vision statement, ‘To be a world-class sustainable chemical companymaking great products for society’, is backed by decarbonization and broader sustainability strategies as key di fferentiators going forward. This sharper focus will enable us to respond to any future uncertainties and improve our position in the post-pandemic era. 9 SUSTAINABILITY REPORT 2021 Responsible Business and Effective Governance Driving Sustainable Value Creation and Growth Towards Net Zero Carbon Empowering Our People and Communities Global Performance Data GRI Standard Content Index

FOCUS ON SUSTAINABLE AND GREEN FINANCE IVL drives leadership in sustainable finance through our Sustainability PerformanceTargets (SPTs), allowing us to issue innovative investment instruments that are linked to sustainability performance. The SPTs are part of our Sustainability-Linked Finance Framework which is independently assessed. IVL’s pioneering approach to green finance in Thailand is reflected in our first issuance of THB 10 billion in Sustainabi l ity Linked Bonds (SLBs) , which drew considerable interest from institutional investors. The SLB is linked to our environmental performance and serves as an important step in optimizing our capital structure, as well as incentivizing our company and stakeholders towards environmental goals. It marks an important development in the Thai capital market as investors focus more on environmental metrics, specifically relating to climate change. Additionally, in 2021, wewere the firstThailand-based company to invest in HSBC’s Green Deposit to support a wide range of environmental, social and governance projects. STRONGER PERFORMANCE, GREATER INNOVATION IVL is effectively integrating our operations, both downstream in packaging and upstream in feedstocks and Integrated Oxides and Derivatives (IOD), while diversifying our product range, notably in surfactants, through strategic acquisi t ions and operat ional enhancements. Our naphthaletes unit, which was established last year at our integrated production facility in the U.S., makes us the world’s largest PNDA producer, with the greatest level of purity to serve high-end polyester markets. Our strategic acquisition of Brazil-based Oxiteno is part of our strategy to make value-accreting investments. The acquisition adds a unique portfolio of high-value surfactants and significantly extends our existing IOD business. It will also strengthen our position in Mexico and Latin America, and in green chemical innovation. We are strengthening our position as a global recycling leader. In 2021, we completed our acquisition of PET recycling assets from CarbonLite Holdings and its subsidiaries inTexas.We alsoannouncedanewgreenfield recycling facility in Karawang, Indonesia which will recycle almost two billion plastic bottles annually in support of our commitment to clean oceans and closed-loop solutions. We acquired the state-of-the-art assets of Ngoc Nghia, amarket leader in PET, preforms and closures inVietnam. The deal will increase our presence in a high-growth market offering a full range of PET packaging solutions with enhanced operational excellence. At the end of last year, we inaugurated our Global Business Service Center in Kolkata, India, which plays an important role for our operating sites worldwide by consolidating large-scale processes and deploying cutting-edge technology to drive operating efficiencies and promote our sustainability and transformation journey. 10 INDORAMA VENTURES PCL.

ADDRESSING SAFETY INCIDENTS AND IMPROVING EMPLOYEE SAFETY Whi le we strive to achieve a strong operational per formance wi thin safe work env i ronment s , unfortunately incidents do occur. In 2021, we suffered two work-related fatalities in Texas in the U.S. and in Egypt (a contractor) while another employee was permanently disabled. Mitigation and enforcement actions were undertaken immediately at both facilities to improve employee safety together with additional training. Two of our facilities experienced fires, and proper reporting and response procedures were immediately followed in both instances. We carried out a detailed investigation of each incident and undertook mitigation actions, while lessons were shared across IVL. Regretfully, there were a total of 16 pandemic-related employee deaths last year, up from seven in 2020. CULTURE OF LEADERSHIP AND SUCCESS As a signatory of the UN Global Compact, we support its 10 principles and promote its core values to showcase our collective work as part of the international business community and to demonstrate our leadership in taking effective action. We are also playing a constructive role in achieving the U.N.’s Sustainable Development Goals (SDGs). Last year, we achieved sustainability recognitions from DJSI, CDP, MSCI, EcoVadis, Sustainalytics, Stock Exchange of Thailand and FTSE4Good, among others. A FUTURE OF NEW VALUE CREATION We are building sustainability across all our businesses while our colleagues work diligently towards making IVL a future-ready organization. The past year has demonstrated IVL’s efforts insustainabilityandpromoting a more circular economy by increasing our presence in recycling and working more closely with stakeholders to invest inour people and theplanet through innovation and product development. As we go forward, developing our people is a top priority. Succession planning is critical to long-term success, and wemust recruit, train, and promote outstanding leaders with the correct ‘growth mindset’. We will include more bio-based feedstock into our goods, with an aim of investing US$ 4.7 billion for bio-based feedstock consumption and a target to achieve our target of 16% bio-based feedstock consumption against the whole IVL feedstock target by 2030. We will also focus on our segment strategy to allow each of our three segments to reach their full potential. Finally, digitalization of our business is a vital component of change. We would l ike to acknowledge our employees, stakeholders, business partners and associates for their cont inued suppor t in mak ing 2021 a year of accomplishment. 11 SUSTAINABILITY REPORT 2021 DILIP KUMAR AGARWAL Chief Executive Officer and Chief Financial Officer Member of Sustainability and Risk Management Committee Responsible Business and Effective Governance Driving Sustainable Value Creation and Growth Towards Net Zero Carbon Empowering Our People and Communities Global Performance Data GRI Standard Content Index

The key to our success will be responding to consumer needs for sustainable products that prioritize health, safety and well-being, and promote economic growth. We are work ing wi th par tners to col lect more post-consumer PET bottles and improve awareness about recycling and PET’s value. For example, we teamed up with Coca-Cola (Thailand), private companies, and environmental start-up Trash Lucky to encourage consumers to separate their recyclables at home. Our recycling education program has expanded to Mexico, the Philippines and Indonesia, and we are working towards reaching one million consumers by 2030. BECOMING A MORE SUSTAINABLE COMPANY In the year ahead, we will continue to collaborate with partners to solve the issue of plastic waste. I am excited about our product innovations, the new technologies we are exploring, including CCUS, our ongoing focus on GHG reductions, and improving the conservation of natural resources and biodiversity. I am pleased to note that IVL was the first company in Thailand to publish a report linked to the UN SDGs. We are integrating the SDGs into our strategy to operate responsibly and with a sustainability mindset. Last year, we achieved sustainability recognitions from DJSI, CDP, MSCI, EcoVadis, Sustainalytics and FTSE4Good, among others.We ranked first in ChemScore among the world’s top 50 chemical producers assessed by ChemSec based on our environmental impact and management of hazardous chemicals. Moreover, we received the highest recognition level, a platinummedal, among the top1%of companies assessedby EcoVadis on sustainable supply chain management. My passion for sustainability continues as we expand and improve our position in recycling globally and find the right solutions to reduce our emissions. We are already leading the way in PET sustainability and will improve further by achieving Net Zero Carbon. In doing so, we will safeguard the trust of our stakeholders as a world-class sustainable chemical company. I appreciate the time and effort put in by the IVL team and all of our partners as we demonstrate our capacity for change and continue to pursue our ambitious goals to place sustainability at the core of all that we do.

22 INDORAMA VENTURES PCL. VISION - TO BE A WORLD-CLASS SUSTAINABLE CHEMICAL COMPANY MAKING GREAT PRODUCTS FOR SOCIETY. IVL delivered record results in 2021, with full year Core EBITDA of US$ 1,743million as well as record production volumes of 14.72 million tons. Growth was seen across all three business segments of Combined PET (CPET), Fibers, and Integrated Oxides and Derivatives (IOD) as well as across the three major regions of NorthAmerica, Europe and Asia. This year has further highlighted the competitive advantage of IVL’s regionally integrated model, serving demand inelastic end markets that provide safety and well-being for the consumer. The resiliency of our platform today sets a strong foundation for further growth in, around, and beyond our current businesses. The year has been marked by some unexpected and unforeseen crises starting with the Polar Vortex in the US Gul f Coast leading to supply disrupt ions of petrochemicals, the unprecedented escalation in container tariffs increasing costs and causing delays, and the energy surge especially in Europe and China further complicating supply chains and resulting in cost hikes that could impact profitability. IVL was able to leverage its leadership position to levy surcharges in Q4 in order to recuperate some of the increased energy costs. Management responded with agility, working closely with customers to fulfill their needs and growing our sales amidst these disruptions. Despite the challenges, there were a number of tailwinds supporting IVL in 2021 which contributed to the record performance achieved. IVL’s presence in premiumwesternmarkets led tomargin improvement coming fromhigher import parity pricing as a result of high freight rates. Our performance in the last quarter of 2021 specifically benefited from the introduction of China’s dual control policy that caused production disruptions, resulting in higher polyester value chain margins. IVL’s global footprint draws integrated premiums over Asian benchmarks and protection against geopolitical risks, while strong integration levels allow IVL to capture value from the entire chain. For the Integrated PET vertical, this unique model has resulted in IVL spreads consistently outperforming industry reference spreads, with premium Western markets making up 71% of EBITDA share of the total business in 2021. Supply chain disruptions and related uncertainties are driving trade preferences for locally sourced goods. IVL’s balanced footprint across Americas, Europe and Asia makes us a supplier of choice.
