I. Comparison of Consolidated Revenue for June 2026 vs. May 2026: Nanya's consolidated revenue in June 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$280 million), representing a 5.9% decline. In June, the Middle East situation gradually eased, leading to a general decline in raw material prices. Customer procurement remained cautious in the first half of the month, 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 disruptions among Middle East peers affected EG supply. Furthermore, demand for summer-grade PET pellets, electronic films, and construction materials for commercial and office projects showed mild growth, causing order intake across product lines to stabilize progressively in late June, with performance bottoming out and recovering.

Meanwhile, electronic materials remained unaffected by geopolitical conflicts and raw material price fluctuations, maintaining strong performance. Market demand for PCBs, copper-clad laminates (CCL), and all related products remained robust, with supply unable to meet demand. Prices were raised month-on-month, further expanding margins, and both revenue and profitability continued to surge. Details are as follows:

(1) Electronic Materials Revenue Increased by NT$500 million (Price Difference +NT$500 million): The supply-demand gap for products such as ABF substrates, CCL, copper foil, and glass cloth widened further. The company actively advanced the certification and sales of high-end materials for the AI supply chain, with smooth progress. Consumer-grade materials also continuously upgraded, driving price increases and boosting revenue. Currently, the capacity utilization rate for products like CCL 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. By implementing high-value strategies across all product lines and leveraging optimal material combinations, the company fully exploits 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$230 million): a. EG: Decreased by NT$990 million (Volume Difference -NT$890 million, Price Difference -NT$100 million) Due to damage to peer facilities from the Middle East conflict, EG market supply decreased, causing selling prices to fall less than raw material prices, thus expanding margins. Nanya's two EG 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$440 million (Volume Difference -NT$370 million, Price Difference -NT$70 million) Plasticizer Series: Decreased by NT$250 million (Volume Difference -NT$190 million, Price Difference -NT$60 million) Falling oil and raw material prices led to customer caution and conservative ordering, reducing revenue.

(3) Plastic Processing Products Revenue Decreased by NT$270 million (Volume Difference -NT$230 million, Price Difference -NT$40 million): Fluctuating and declining raw material prices led to conservative customer procurement and reduced shipment volumes. However, downstream inventories are already low. In response to construction project starts and composite material demand driven by the electronics industry, orders began to recover gradually in late June.

(4) Polyester Products Revenue Decreased by NT$190 million (Volume Difference -NT$230 million, Price Difference +NT$40 million): The market观望 atmosphere has nearly ended, and performance declines have converged. Combined with order inflows from electronic and optical film materials and summer-grade PET pellets, overall performance has stabilized after a period of decline.

II. Comparison of Consolidated Revenue for June 2026 vs. June 2025: Compared to June 2025, Nanya's consolidated revenue in June 2026 increased by NT$6.54 billion (volume difference: +NT$1.34 billion, price difference: +NT$5.2 billion), representing 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 less low-price dumping compared to last year. Plastic processing product revenue rose as raw material prices remained higher than the same period last year, leading to higher product prices and revenue. Chemical product revenue declined due to customer观望 on expected price drops for 2EH and BPA. Details are as follows:

(1) Electronic Materials 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, leading to a rapid increase in capital expenditures. This not only drives a surge in demand for high-end supply chain materials but also causes basic materials for consumer and application ends to become supply-constrained and rapidly upgrade. The company's capacity utilization rates for IC substrates, CCL, copper foil, and glass cloth (yarn) have significantly increased compared to 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$840 million (Volume Difference -NT$220 million, Price Difference +NT$1.06 billion): Due to factors such as Middle East geopolitical conflicts, oil price and freight rate volatility, and U.S. tariff policies, U.S. companies' willingness to import raw materials from overseas has decreased, improving the situation of low-price dumping of Asian goods. This supports normal pricing in the U.S. market and increases revenue.

(3) Plastic Processing Products Revenue Increased by NT$220 million (Volume Difference -NT$130 million, Price Difference +NT$350 million): Although the U.S.-Iran conflict is gradually easing, oil and raw material prices remain higher than the same period last year, leading to relatively higher revenue.

(4) Chemical Products Revenue Decreased by NT$650 million (Volume Difference -NT$1.31 billion, Price Difference +NT$660 million): a. Plasticizer Series: Decreased by NT$260 million (Volume Difference -NT$500 million, Price Difference +NT$240 million) Mainly due to market expectations of price declines, 2EH customers观望, leading to reduced sales volume. b. BPA: Decreased by NT$240 million (Volume Difference -NT$340 million, Price Difference +NT$100 million) Customers postponed orders due to expected price declines, reducing revenue. c. EG: Decreased by NT$150 million (Volume Difference -NT$450 million, Price Difference +NT$300 million) Part of the June orders in Texas were shipped in May due to vessel scheduling, resulting in relatively lower delivery volumes.
