Volume contributed +NT$4.56 billion, while price decreased by -NT$960 million. (b) Sales volume analysis: 1. FCFC: +NT$3.04 billion Due to fluctuating market conditions caused by geopolitical factors, the company strengthened sales efforts and inventory clearance. PX, SM, PS, ABS, and PP sales increased by NT$2.76 billion; downstream demand recovery for PTA and PIA boosted sales by NT$210 million. 2. FCFC Ningbo: +NT$1.56 billion Mainly due to PTA-6 resuming operations after scheduled maintenance and PTA-5 production ramp-up, resulting in NT$1.38 billion increase in output and sales. PS and ABS inventory reduction added NT$230 million. Downstream PIA demand increased sales by NT$120 million. However, raffinate oil sales adjustment reduced external sales by NT$210 million. 3. Other subsidiaries: Vietnam FIC’s power units reduced operating hours per national grid dispatch, decreasing sales by NT$380 million. Taiwan Acetic Acid enhanced sales in response to market demand, increasing revenue by NT$210 million. (c) Pricing aspect: Ongoing U.S.-Iran tensions, including ceasefire breakdowns, caused volatile market conditions. Customers remained cautious, and some competitors engaged in price-cutting, leading to lower average prices for petrochemical and plastic products compared to the previous month. II. Comparison of consolidated revenue in July 2026 versus July 2025: (a) July 2026 consolidated revenue of NT$31.267 billion increased by NT$7.96 billion (34.2%) from NT$23.303 billion in July 2025. Volume difference contributed +NT$820 million, while price difference accounted for +NT$7.14 billion. (b) Sales volume analysis: 1. FCFC: +NT$840 million Increased external sales of PX (reduced self-use) and resale of raffinate oil to Formosa Plastics totaled +NT$1.86 billion. However, SM, phenol, OX, PS, ABS, and PP saw combined declines of NT$1.09 billion due to weak downstream demand and volatile crude oil and raw material prices, causing customers to place orders cautiously. 2. FCFC Ningbo: +NT$120 million PTA-6 restart after maintenance and PTA-5 capacity expansion increased PTA output and sales by NT$930 million. However, ABS faced chaotic market conditions due to volatility and competitor price wars, leading to just-in-time purchasing and a NT$470 million decline. Raffinate oil sales adjustment reduced revenue by NT$210 million. Phenol customers cut production, reducing pickup demand by NT$100 million. 3. Other subsidiaries: Taiwan Acetic Acid had accumulated inventory pre-maintenance last year, reducing sales then; this year’s normal operations led to a NT$160 million increase. Far Eastern Century Textile experienced seasonal shift in apparel orders, reducing sales by NT$270 million. (c) Pricing aspect: Geopolitical conflicts between the U.S. and Iran drove up crude oil and petrochemical feedstock prices, elevating product market levels. Additionally, optimized product mix with higher proportions of differentiated products lifted average selling prices.
