  1. Letter to Shareholders
    1. Foreword

      In 2025, the global economy demonstrated resilience driven by advances in AI technologies. According to the IMF, the global growth rate reached 3.2%, mainly due to the easing inflation of economies, and monetary policies' gradual shifting from tightening to loosening. Taiwan benefited from a strong New Taiwan Dollar and stabilized raw material prices, with the CPI annual growth rate dropping to 1.66%.

      Despite these efforts, the overall operating environment for the petrochemical industry remains highly challenging. Uncertainties stemming from the international geopolitical and economic landscape, continued capacity expansion in China, volatility in crude oil prices and exchange rates, as well as green transition policies in Europe and the United States, have all exerted downward pressure on demand for traditional petrochemical products and increased cost pressures across the industry. In addition, Taiwan's carbon pricing mechanism, which officially came into effect in 2025, has directly added to operating costs. Although Taiwan's economic growth has been supported by the development of the AI and semiconductor industries, the spillover benefits to the petrochemical sector remain relatively limited.

      In response to changes in the external environment, EO Materials continues to uphold a prudent operating strategy by further enhancing process optimization and cost management across its production sites in Taiwan and China. Leveraging ethylene oxide (EO) as its core technology platform, the Company is focusing on the development of specialty materials, electronic chemicals, and green materials related to new energy applications, while continuously optimizing its product portfolio and increasing the proportion of specialty chemicals. At the same time, the Company is actively advancing energy-saving, carbon-reduction, and self-initiated emission reduction measures to mitigate the impact of the carbon pricing regime.

      In 2025, OUCC's consolidated operating revenue reached NT$22.3 billion. Affected by the overall industry environment, an attributable net loss after tax of the Company totaled NT$887 million, of EPS NT$-1.01.

    2. Operating Performance Review
      1. Safety, Health, and Environment

        OUCC operates with a commitment to green sustainability, practicing circular-economy principles and placing strong emphasis on occupational safety, health, and environmental protection. In addition to balancing chemical-production development with environmental preservation, the Company continuously improves process design and invests in equipment upgrades to recycle homogeneous waste materials for reprocessing, thereby reducing environmental impact.

        OUCC has long invested in the development of carbon capture and utilization (CCU) technologies, successfully converting carbon dioxide emitted during production into value-added products. By capturing CO₂ generated within its processes, the Company not only reduces direct emissions but also refines CO₂ into ultra-high-purity carbon dioxide for sale to industrial, food, and electronics sectors. CO₂ can also be reacted with ethylene oxide (EO) to produce ethylene carbonate (EC), supplied for applications such as polycarbonates, composite materials, and lithium-battery electrolytes.

        To achieve eco-friendly and high-value product development, OUCC's R&D is guided by the themes of "green, low-carbon, and advanced materials." The Company continues to introduce environmentally friendly materials and application technologies. OUCC produces high-performance carbon-capture solvents such as ethanolamines and ethylenediamines co-products, supporting customers' carbon-capture efforts. In parallel, the Company actively develops CO₂-based chemicals, plastic-recycling technologies, and biodegradable materials to help address global CO₂-emission challenges. These materials not only reduce carbon footprints during production but also provide downstream benefits such as energy savings, waste reduction, recyclability, and lower environmental toxicity.

      2. EG Business

        In 2025, the ethylene glycol (EG) product line continued to be influenced by China's substantial

        new capacity, resulting in persistent supply-demand imbalance and downward pricing pressure.

        The Company's consolidated revenue for the EG business in 2025 amounted to NT$14,585,456 thousand (-3.5% YoY). Total EG production reached 540,000 MT (+6% YoY), while sales volume reached 550,000 MT (+4% YoY).

        For ethylene oxide (EO), combined production across Taiwan and China reached 330,000 MT, up 6% compared to 2024, with sales volume at 220,000 MT, a 10% increase.

      3. Gas Business

        In response to changing demand patterns in downstream gas-related industries, the Company continued to leverage its advantages in pipeline-supplied gases within industrial park aligned with liquified gases to strategically expand its diversified customer base. Sales volumes remained stable or decreased slightly depending on market conditions.

        Driven by decarbonization trends, liquified carbon dioxide (LCO₂) has become a priority material for industries seeking to reduce emissions. Recovery of CO₂ from production processes has become increasingly common, resulting in growing supply and gradually softening market prices.

        In 2025, the consolidated revenue of the Company's gases business reached NT$1,625,894 thousand (+2.4% YoY). Excluding oxygen used for self-consumption, total gas sales across Taiwan and China included:

        • 70,000 MT of oxygen, comparable to 2024

        • 320,000 MT of nitrogen, a 3% decrease

        • 170,000 MT of carbon dioxide, a 60% increase

          Notably, sales at Far Eastern Union Petrochemical (Yangzhou) Ltd. rose from 76,000 MT in 2024 to 135,000 MT in 2025.

      4. Specialty Chemicals Business

        In 2025, the Company's specialty-chemicals business was impacted by slowing global demand and regional trade barriers, resulting in an overall decline. Consolidated revenue reached NT$6,041,141 thousand (-14% YoY). Combined production across Taiwan and China totaled 190,000 MT, equal to 2024, while combined sales reaching 190,000 MT (+6% YoY).

        EOD (Ethylene Oxide Derivatives) Products

        EOD products supply downstream industries such as daily chemicals, electronic chemicals, resin synthesis, textile auxiliaries, and construction materials, all of which are highly correlated with macroeconomic conditions. With global economic slowdown and low-price dumping driven by China's excess capacity, overall demand volume and pricing both declined compared to 2024.

        Solvent Chemicals

        The solvent-chemicals product line includes ethanolamines (EAs), ethylene glycol butyl ethers (EBs), and ethylene carbonate (EC). China's significant new EA capacity sharply reduced its import dependence, while capacity for EBs and EC also increased. As lithium-battery electrolyte demand grows, EC demand has risen, intensifying supply-demand competition. OUCC mitigated risks through optimized sales-channel diversification, strengthened domestic sales, maintained R&D advantages, enhanced high-purity applications, and pursued product-differentiation strategies-achieving performance ahead of global peers.

        Amine Chemicals

        The amines portfolio includes ethylenediamines (EDAs) and polyether amines (PEAs), used in chelating agents, agriculture, papermaking, textiles, and electronic cleaning agents. While China's new EDA capacity affected market conditions in recent year, OUCC effectively reduced low-priced competition through flexible product combination of high- and low-amine grades and strategic market restructuring, acquiring broad adoption among domestic and overseas customers. For PEAs, the Company focuses on innovative application development and deepening engagement with terminal markets. Tailored sales strategies based on molecular-weight segments further strengthen OUCC's global competitive position.
