Formosa Petrochemical (TPE:6505) reported consolidated operating revenue of NT$57.8 billion in May, up 27% from NT$45.5 billion a year earlier, according to a Monday filing with the Taiwan Stock Exchange.
The rise is attributable to higher sales prices, the company said.
On a month-over-month basis, revenue fell 6.1% from NT$61.5 billion in April, driven by lower sales prices, partially offset by higher volumes.
