1.Date of occurrence: 2026/06/08 2.Company name: Nanya Plastics Corporation 3.Relationship with the company: The company itself 4.Mutual shareholding ratio: Not applicable 5.Reason for occurrence: Announcement of consolidated revenue for May 2026 6.Response measures: None 7.Other matters to be stated: I. Comparison of consolidated revenue for May 2026 with April 2026: The company's consolidated revenue for May was NT$28.83 billion, an increase of NT$1.15 billion compared to April 2026 (volume difference +NT$0.87 billion, price difference +NT$0.28 billion), a growth of 4.2%. Recently, raw material prices have fallen, but there are still many variables in the Middle East situation, and tariff fluctuations have not yet ended. Global market concerns about inflation and interest rate hikes have increased, leading to insufficient confidence in consumer-related industries, with cautious purchasing and inventory control. However, the AI industry continues to demonstrate resilience. Cloud service providers are accelerating capital expenditures unaffected by geopolitical conflicts and short-term economic changes, driving the expansion of the surrounding supply chain. Nanya has grasped industrial development trends and actively deployed high-value electronic materials, achieving good results and rising performance. Additionally, the Texas EG plant was not impacted by the Middle East situation, with both production lines fully operating and selling, leading to significant revenue growth, pushing Nanya's May consolidated revenue to a 47-month high. Details are as follows: (A) Chemical product revenue increased by NT$1.14 billion (volume difference +NT$1.20 billion, price difference -NT$0.06 billion): 1. EG increased by NT$1.59 billion (volume difference +NT$1.52 billion, price difference +NT$0.07 billion) Compared to the impact of the US-Iran war on Middle East peers' production capacity and raw material supply, Nanya's Texas EG plant's production, sales, and transportation were unaffected by the Middle East situation. Both units maintained full production, increasing sales volume and revenue. 2. Plasticizer series decreased by NT$0.24 billion (volume difference -NT$0.22 billion, price difference -NT$0.02 billion) Downstream processors reduced orders due to the May Day holiday. 3. BPA decreased by NT$0.17 billion (volume difference -NT$0.06 billion, price difference -NT$0.11 billion) Selling prices fell with raw material costs, revenue decreased. (B) Electronic materials product revenue increased by NT$0.39 billion (volume difference +NT$0.19 billion, price difference +NT$0.20 billion): Cloud service providers, optimistic about rapidly growing AI demand, are actively building related facilities and deploying future computing power. They have not slowed expansion due to war or inflation but have accelerated investment, driving capital expenditures to new highs and fueling the entire supply chain. Nanya's electronic materials layout is closely integrated with the long-term development of the AI industry and also boasts leading technology quality and production scale for the broad consumer product market. Recently, it has maintained high capacity utilization, with sales prices and volumes rising, leading to revenue growth. (C) Polyester product revenue decreased by NT$0.34 billion (volume difference -NT$0.54 billion, price difference +NT$0.20 billion): High prices affected consumer purchasing power, leading the industry to turn cautious, with conservative ordering and strict inventory control, resulting in lower product sales. (D) Plastic processing product revenue decreased by NT$0.12 billion (volume difference -NT$0.06 billion, price difference -NT$0.06 billion): The Middle East situation caused rising price indices, reigniting inflation concerns. Discussions on interest rate hikes have generally increased across countries, market consumer confidence is insufficient, and product revenue declined. II. Comparison of consolidated revenue for May 2026 with May 2025: Consolidated revenue for May 2026 increased by NT$6.88 billion compared to May 2025 (volume difference +NT$1.66 billion, price difference +NT$5.22 billion), a growth of 31.4%. Among them, electronic materials products saw significant revenue increases as the AI industry developed and the high-value process progressed smoothly. Other products also saw notable price increases driven by rising crude oil and raw material prices, leading to revenue growth. Details are as follows: (A) Electronic materials product revenue increased by NT$4.70 billion (volume difference +NT$2.04 billion, price difference +NT$2.66 billion): The company is committed to developing mid-to-high-end electronic materials, gradually showing good results in servers, network equipment, and high-performance computing, with significant performance growth. At the same time, due to resource crowding, the supply of mid-range and basic electronic materials has tightened. The company's ample and stable production capacity contributed to operations, increasing consumer product performance. Overall electronic materials revenue grew substantially year-on-year. (B) Polyester product revenue increased by NT$0.91 billion (volume difference -NT$0.08 billion, price difference +NT$0.99 billion): The Middle East war caused raw material prices to surge, and product selling prices rose accordingly, increasing revenue. (C) Chemical product revenue increased by NT$0.71 billion (volume difference -NT$0.48 billion, price difference +NT$1.19 billion): 1. EG increased by NT$0.65 billion (mainly price difference +NT$0.65 billion) Affected by the US-Iran war, Middle East peers' facilities were damaged, impacting supply. Additionally, raw material and product transportation was hindered, causing EG prices to rise and revenue to increase. 2. BPA increased by NT$0.02 billion (volume difference -NT$0.20 billion, price difference +NT$0.22 billion) Due to limited raw material supply and rising prices, product selling prices were adjusted, increasing revenue. (D) Plastic processing product revenue increased by NT$0.40 billion (volume difference +NT$0.01 billion, price difference +NT$0.39 billion): The prolonged war led to rising energy and raw material prices. To reflect costs, product selling prices were raised, increasing revenue.
