-- Formosa Chemicals and Fibre (TPE:1326) booked net profit attributable to owners of NT$6.25 billion, or NT$1.07 per share, for the first quarter, according to a Friday Taiwan Exchange filing.
Shares jumped about 9% in Monday's afternoon trade.
Revenue for the quarter reached NT$81.75 billion, up 3.6% versus a year earlier, driven by higher sales volume and improved pricing.
The company said profitability was boosted by better aromatics margins, higher production and sales, and gains from equity-method investments, particularly from Formosa Petrochemical.
