###### Climate Change Response
Hyosung Corporation has established the ESG Management Committee within the board of directors (BoD) to address climate change at the corporate level. The operating companies handle climate change issues through the ESG Management Promotion Committee and the R&D Committee, which are the highest decision-making bodies under the CEO. They report major agenda items to the BoD on a regular basis. [...] Our Board of Directors (BoD) and ESG Management Committee are responsible for deliberating on ESG-related policies, establishing related goals, managing risks, and developing investment and action plans. Our board includes outside directors from diverse backgrounds and with expertise in various fields, allowing for in-depth discussions and management of climate issues. For example, a former Minister of Environment served as a member of Hyosung Corporation's ESG Management Committee as a climate change and energy expert until March 2023. In April 2023 a former Minister of Trade Industry and Energy joined us as an outside director [...] The ESG Management Promotion Committee, under the supervision of the CEO, oversees not only the environmental, safety, and health aspects, but also the social and governance aspects of the company. It operates on a quarterly basis and selects major agenda items to be submitted or reported to the BoD. The R&D Committee is joined by the CEO and the management, and it operates on a semiannual basis to establish R&D strategies that reflect the opinions of climate change-related departments, such as sales, marketing, development, and research. [...] The dedicated organization consists of the ESG Management Department under the CEO and the Green Management Team under the Strategy Division, and is responsible for establishing climate change strategies, managing implementation, and disclosing performance. Onsite utility and production departments are charged with reducing energy usage and GHG emissions. [...] Hyosung has established dedicated organizations for ESG management and climate change in each operating company to address the global challenge of climate change. Hyosung TNC, Hyosung Heavy Industries, and Hyosung Chemical have formed the ESG Management Promotion Committee under the leadership of the CEO, and they submit or report major agenda items from the committees to the BoD. Hyosung Advanced Materials operates both the Sustainability Steering Committee and subcommittees for each sector to deliberate on climate change issues, and they present and report major agenda items to the BoD.
