Cross-shareholding Ratio: Not applicable 5. Reason for Occurrence: Announcement of the Company's consolidated revenue for June 2026 6. Response Measures: None 7. Other Matters to be Disclosed (If the subject of the event or resolution is a publicly issued company or above, this major information also complies with Article 7, Paragraph 9 of the Enforcement Rules of the Securities and Exchange Act, regarding matters significantly affecting shareholders' rights or securities prices):

I. Comparison of June 2026 Consolidated Revenue with May 2026: The company's consolidated revenue for June 2026 was NT$27.13 billion, a decrease of NT$1.7 billion compared to May 2026 (volume difference: -NT$1.98 billion, price difference: +NT$0.28 billion), representing a 5.9% decline. In early June, the Middle East situation gradually eased, leading to a general decline in raw material prices. Customers remained cautious in procurement, resulting in reduced sales volume and revenue for chemical, plastic processing, and polyester products. However, as raw material prices gradually returned to pre-war levels, downstream观望 attitudes began to subside, and inventory restocking commenced. Additionally, production capacity damage among Middle East peers affected EG supply. Furthermore, demand for summer-grade bottle resin, electronic films, and construction materials for office and commercial buildings showed mild growth, causing order stability to gradually improve in late June, leading to a bottoming out and recovery in performance.

Meanwhile, electronic materials were unaffected by geopolitical conflicts or raw material price fluctuations, maintaining strong performance. Products such as PCBs and copper-clad laminates experienced strong market demand and supply shortages, with prices increasing monthly, further expanding margins, and driving continuous growth in revenue and profitability. Details are as follows:

(1) Electronic Materials Product Revenue increased by NT$0.5 billion (price difference: +NT$0.5 billion): The supply-demand gap for ABF substrates, copper-clad laminates, copper foil, and glass cloth further widened. The company actively promoted certification and sales of high-end materials for AI supply chains, with smooth progress. Consumer-grade materials continued to upgrade and increase prices, driving revenue growth. Currently, the production capacity utilization rate for copper-clad laminates and other products remains above 90%. The company has successfully expanded into advanced resins, high-end glass cloth (yarn), and copper foil, serving both internal use and external sales, implementing high-value strategies across all product lines. Through optimal material combinations, the company fully leverages its vertical integration advantages to continuously enhance competitiveness.

(2) Chemical Products Revenue decreased by NT$1.73 billion (volume difference: -NT$1.5 billion, price difference: -NT$0.23 billion): a. EG decreased by NT$0.99 billion (volume difference: -NT$0.89 billion, price difference: -NT$0.1 billion): Middle East war impacts damaged peer facilities, reducing EG market supply and causing selling prices to decline less than raw material prices, thus expanding margins. Two EG production lines in Texas operated at full capacity in response to market conditions. However, 33,000 tons of June orders were shipped in May to align with vessel schedules, resulting in relatively lower delivery volumes and revenue. b. BPA decreased by NT$0.44 billion (volume difference: -NT$0.37 billion, price difference: -NT$0.07 billion) Plasticizer series decreased by NT$0.25 billion (volume difference: -NT$0.19 billion, price difference: -NT$0.06 billion) Falling oil and raw material prices led to customer caution and conservative ordering, reducing revenue.

(3) Plastic Processing Products Revenue decreased by NT$0.27 billion (volume difference: -NT$0.23 billion, price difference: -NT$0.04 billion): Fluctuating and declining raw material prices led to conservative customer procurement and reduced pickup volumes. However, downstream inventories are low, and orders gradually warmed up in late June due to construction project starts and composite material demand driven by the electronics industry.

(4) Polyester Products Revenue decreased by NT$0.19 billion (volume difference: -NT$0.23 billion, price difference: +NT$0.04 billion): The market's观望 atmosphere is nearing its end, with performance declines converging. Combined with order injections from electronic and optical film materials and summer-grade bottle resin, overall performance stabilized after a decline.

II. Comparison of June 2026 Consolidated Revenue with June 2025: Compared to June 2025, June 2026 consolidated revenue increased by NT$6.54 billion (volume difference: +NT$1.34 billion, price difference: +NT$5.2 billion), a 31.8% growth. Electronic materials products continued to advance product certification and sales in line with the AI wave, achieving significant performance growth. Polyester product revenue increased due to improved market conditions with reduced low-price dumping compared to last year. Plastic processing product revenue rose as raw material prices were higher than the same period last year, leading to increased product prices and revenue. Chemical product revenue decreased as customers for 2EH and BPA adopted观望 attitudes due to expected price declines. Details are as follows:

(1) Electronic Materials Product Revenue increased by NT$5.93 billion (volume difference: +NT$2.79 billion, price difference: +NT$3.14 billion): AI-related companies are actively building data centers, rapidly increasing capital expenditures. This not only drove a surge in demand for high-end supply chain materials but also caused basic materials for consumer and application ends to become supply-constrained and rapidly upgrade. The company's IC substrate, copper-clad laminate, copper foil, and glass cloth (yarn) production capacity utilization rates were significantly higher than the same period last year, with substantial growth in sales volume and prices, bringing considerable revenue and profit.

(2) Polyester Products Revenue increased by NT$0.84 billion (volume difference: -NT$0.22 billion, price difference: +NT$1.06 billion): Affected by Middle East geopolitical conflicts, oil prices and shipping costs volatility, and U.S. tariff policies, U.S. companies' willingness to import raw materials from overseas decreased, improving the situation of low-price dumping of Asian goods, benefiting normal pricing in the U.S. market and increasing revenue.

(3) Plastic Processing Products Revenue increased by NT$0.22 billion (volume difference: -NT$0.13 billion, price difference: +NT$0.35 billion): Although U.S.-Iran tensions are gradually easing, oil and raw material prices remain higher than the same period last year, leading to relatively increased revenue.

(4) Chemical Products Revenue decreased by NT$0.65 billion (volume difference: -NT$1.31 billion, price difference: +NT$0.66 billion): a. Plasticizer series decreased by NT$0.26 billion (volume difference: -NT$0.5 billion, price difference: +NT$0.24 billion): Mainly due to market expectations of price declines, 2EH customers adopted观望 attitudes, reducing sales volume. b. BPA decreased by NT$0.24 billion (volume difference: -NT$0.34 billion, price difference: +NT$0.1 billion): Customers postponed orders due to expected price declines, reducing revenue. c. EG decreased by NT$0.15 billion (volume difference: -NT$0.45 billion, price difference: +NT$0.3 billion): Part of Texas's June orders were shipped in May due to vessel schedule adjustments, resulting in relatively lower delivery volumes.
