Dear Business Partners, PolyMirae was founded in 2000 by our current shareholders, DL Chemical and LyondellBasell, who jointly began a new company to run the polypropylene business with a bold and macro perspective. Since then, PolyMirae has achieved multiple significant milestones and major achievements, and has realized our vision to become the most admired company in the related industries. PolyMirae has established itself as a model for operational excellence and of safety/environment/health, as well as widely recognized by the industry for its product portfolio, quality, customer service, and reliable supply. PolyMirae hopes to continue to succeed in the future to deliver outstanding value to our customers, employees, suppliers, service providers, communities and shareholders. In addition, we face a very challenging time due to intensifying competition in the petrochemical industry and the volatility in the global economy. The petrochemical industry, in particular, is expected to face a difficult time that we have not experienced during our phase of growth due. However, I am confident that our employees will be innovative and passionate about their work and we will overcome any difficulties that may arise. In doing so, we’ll differentiate ourselves from others in the polypropylene industry as an example for others to follow. I look forward to seeing a dynamic and successful future with you. Thank you. 2023.03.13 President and CEO Mitchell Ian Killeen POLYMIRAE

CEO问候语 亲爱的商业伙伴们， PolyMirae由我们目前的股东Daelim和LyondellBasell于2000年创立，他们联合成立了一家新公司，以大胆和宏观的视角经营聚丙烯业务。 此后，PolyMirae取得了多项重大里程碑和重大成就，实现了成为相关行业最受推崇公司的愿景。 Polymirae已成为卓越运营和安全/环境/健康的典范，并因其产品组合、质量、客户服务和可靠供应而广受业界认可。 此外，由于石化行业的竞争加剧和全球经济的波动，我们面临着一个非常具有挑战性的时刻。特别是石化行业，预计将面临一个困难时期，这是我们在增长阶段所没有经历的。 不过，我相信我们的员工会有创新精神，对自己的工作充满热情，我们会克服任何可能出现的困难。在这样做的时候，我们将把自己与聚丙烯行业的其他公司区别开来，作为其他公司效仿的榜样。 我致力于扮演领导者的角色，并根据我在聚米拉和聚丙烯行业的经验解决我们面临的问题。 我期待着和你一起看到一个充满活力和成功的未来。谢谢。 总裁兼首席执行官 Kim, Bang Hyun POLYMIRAE

In PolyMirae, we work based on a management philosophy that places safety as the top priority To improve the safety culture of the company and maintain a safe working environment for all the employees of PolyMirae and our partner companies, we actively execute and manage a set of activities including safety training for all personnel including visitors, a Global Safety Day event, Safety Inspection Day, Safety Campaigns and more. LyondellBasell Operational Excellence Audit To maintain its world-class safety management system, every four years PolyMirae invites LyondellBasell’s experts in each field to conduct an audit on process safety and risk management within the company, with self-audits such as PSM, ISO and RC. These invitational audits involve a management system inspection, on-site inspection and employee interview to identify risk factors and potential improvements, and the degree of improvement is tracked and managed through continued investment and actions. Safety Inspection Day At PolyMirae, employees with expertise in each field patrol together with employees of the plant every second Tuesday of the month to identify potential risks and improvements in all fields including safety, health, environment and process. Identified potential improvements are tracked and managed until completion. Contractor Cooperation Program To seek development in the safety and health management of establishments, PolyMirae organizes a Coexistence Cooperation Meeting with its partners, and holds monthly meetings to assess potential risks and actively engage in supportive activities to offset any identified risks. CCG CAMPAIGN CCG Campaign Clean Caution Green PolyMirae reports the progress and potential improvements of all inspections, including internal/external safety inspections and parent company inspections, to its executives on a monthly basis, and continuously tracks and manages the details.

Comprehensive Medical Check-up and Vaccination PolyMirae provides comprehensive medical testing and vaccinations for all employees and their spouses in order to detect employee illnesses in their early stages and assist in systematic employee health management, so that employees can perform their duties with a good health condition. PolyMirae is continuously investing in improving its process safety-related facilities to ensure public safety and protect the health of executives, employees and partners, as well as to prevent major industrial accidents.

Spatial Infrared Gas Detector PolyMirae has improved its gas leakage detectability and has introduced, the first between in the Korea industry, the first spatial infrared gas detector. In contrast to the generally used spot-type detector, which detects gas only when the gas enters the sensor inside the detector, five newly-introduced infrared detectors which are installed throughout the entire process detect gas when the leaked gas enters 100~200m of space which the infrared beam passes through. Control Building Clean Air Supply System To protect employees in the event of a toxic gas leakage from adjacent companies or a large-scale inflammable gas leak into the process area, PolyMirae has installed a facility which blocks polluted air from entering the Control Building, supplies clean air and maintains positive pressure. Process Area and Building Risk Assessment PolyMirae has conducted a quantitative assessment of risks such as leakage, fire or explosion on all facilities and buildings in the process to secure employee safety in the event of an emergency, based on which the company has invested in the installation of various facilities and established emergency countermeasures to minimize damage in the most severe accidents. Water Spray Curtain System for Prevention of Gas Diffusion PolyMirae has installed and is operating a water spray curtain system to prevent and suppress the diffusion of inflammable gas to offices adjacent to the process in the event of a large-scale leak. With a management philosophy that makes safety the top priority, PolyMirae is investing actively in strengthening a culture of safety, and applies a range of measures to improve and enhance the safety environment to prevent industrial accidents and achieve a completely accident-free business. PolyMirae regularly and continuously conducts practical emergency response training to minimize human and material damage in emergencies such as earthquake/typhoon/heavy rainfall/warfare/major industrial accidents. Company-wide Emergency Response Training – Once a year Joint Fire Drill – Once a year per plant (3 times in total) Disaster Response Team Training– Once every quarter per plant (12 times in total) Emergency Self-response Training – Once a month per shift (144 times in total) Companywide Emergency Response Training The CEO, the company management team and all employees including those in the headquarter participate in Company-wide Emergency Response Training every year to train communication and procedures, minimize damage and expedite normalization in cases of emergency. Disaster Response Team Training PolyMirae runs a Disaster Response Team Training every quarter to enable a swift and effective response and recovery from potential accidents involving fire and explosion. EMERGENCY Firefighting Response Training PolyMirae conducts joint fire drills with the fire station and adjacent companies, as well as surprise firefighting response drills that occur without notice.
